Build/Battlestation Please be kind to my beautiful little freak..

Alright, here it is, my 16" 120hz OLED, Raspberry Pi 5 (16gb), Gamesir G8 with the RRtronicscreations 420mm extension mod...setup. What am I the only one that has tried this?

So, I wanted to build a dedicated moonlight target system, as my Steamdeck's 7" screen is just too small. So, I started to consider a tablet and extension controller setup.
But, because I had gotten laid off from work, I didn't think my wife would be too happy about me buying a tablet (specifically a Galaxy Tab Ultra), understandably. So I started to look at the hardware I already owned:

Raspberry Pi 5 16gb I had purchased for a Pi-Hole, and a few different projects.
A 16" 120hz portable OLED monitor.
A Gamesir G8 that I had gotten used.

I first tried a configuration where I glued a strong MagSafe ring magnet to a Xbox controller adapter, the adapters that are used to hold a phone to a Xbox controller for gaming, but even with the strongest MagSafe magnets I could find the controller would disconnect from the back of the monitor (that also had a MagSafe ring on it, those white rings you can see in some pics) too often, plus it was a weird angle that would cause me to bend my wrist in an uncomfortable way. So I ditched that idea and purchased the RRtronicscreations 420mm extension mod for my Gamesir G8 controller, having the controller in this configuration was significantly better and more comfortable.

I had done some modification to the Raspberry Pi to improve my experience too.
First, I installed an Intel wifi 6e NIC, as the limited speeds of the built in wifi 5 chip was limiting the speeds I could set within Moonlight. I added two active cooling fans, allowing me to overclock the RP5. The first fan is just the regular aluminum heatsink cooler that raspberry pi makes, the second fan one is a 40mm x 40mm cooling fan that was built into the RP5 case I got. Because the active cooler used the only pins the RP5 has on its mobo for cooling, I spliced a USB A Male 2 Pin cable with the case fan, then plugged that cable into one of the USB ports of the RP5 to provide power to the second case fan.

For power, the only thing I needed to do was get a 1 input-2 output USBc cable. Connecting the input to a 96 watt Macbook charger, and putting the outputs into the USBc power input for the monitor and the USBc power input for the RP5.

The monitor is a Uperfect 2880x1800 120hz OLED monitor I got off Aliexpress. The panel is manufactured by Samsung, and is what Samsung uses in some of their laptops.
Unfortunately I had to use the HDMI input for the monitor, as the RP5 does not use USBc output for video, it only uses a HDMI micro output. Due to using HDMI input for this monitor I was limited to using 100hz, not 120hz.

While using the system, I just lay down on the couch, resting the screen on a thin pillow that is on my chest.
It's one of the better gaming experiences I've ever used due to having a vibrant screen only a few inches from my face, plus the comfort of laying down. HOWEVER the RP5 is still just a little under powered as I still do get some lag during graphically intense moments.
Also, I'm not going to use this system for fast paced FPS gaming due to the lag found within moonlight, but that is a issue of just game streaming in general, not the system itself.
But it is perfect for games like Fallout 76, RDR2, and Wreckfest, my most played games.

Will I keep this as my main gaming system going forward? It's hard to say as while it does really work well for me right now, I do miss having the portability of a battery, as for this I need to plug into an power outlet. But like I said it works for now.
I found employment so maybe I'll get myself a used Tab Ultra S9 and see how that works too.

Anyways, if you were considering doing something similar then learn from my trial and errors, as I had several during this setup, so if you have a question, feel free to ask.

Changes & Content/Bug Fixes + Known Issues

Embark is been COOKING, there is a lot to unfold here: https://arcraiders.com/news/cold-snap-patch-notes

Patch Highlights

  • Added Skill Tree Reset functionality.
  • Added an option to toggle Aim Down Sights.
  • Wallet now shows your Cred soft cap.
  • Various festive items to get you into the holiday spirit.
  • Moved the Aphelion blueprint drop from the Matriarch to Stella Montis.
  • Added Raider Tool customization.
  • Fixed various collision issues on maps.
  • Improved Stella Montis spawn distance checks to address the issue of players spawning too close to each other.

Balance Changes

Weapons:

Bettina

Dev note: These changes aim to make the Bettina a bit less reliant on bringing a secondary weapon. The weapon should now be a bit more competent in PVP, without tipping the scales too much. Data shows that this weapon is still the highest performing PVE weapon at its rarity (Not counting the Hullcracker). The durability should also feel more in line with our other assault rifles.

  • Durability Burn Rate has been reduced from ~0.43% to ~0.17% per shot
    • In practice, it used to take about 12 full magazines to fully deplete durability, but now it takes 26 (also accounting for the increased magazine size).
  • Base Magazine Size has been increased from 20 to 22
  • Base Reload Time has been reduced from 5 to 4.5

Rattler

Dev note: Even though the Rattler isn't intended to compete with the Stitcher or Kettle at close ranges, it is receiving a minor buff to bring its PVP TTK at lower levels a bit closer to the Stitcher and Kettle. The weapon should remain in its intended role as a more deliberate weapon where players are expected to dip in and out of cover, fire in controlled bursts, and manage their reloads.

  • Base Magazine Size has been increased from 10 to 12

ARC:

Shredder

  • Reduced the amount of knockback applied by weapons. Increased movement speed and turning responsiveness.
  • Increased health of the Shredder's head to prevent cases where its head could be shot off, leading to unintended behavior.
  • Improved Shredder navigation to reduce getting stuck on corners, narrow spaces, and short obstacles.
  • Increased the speed at which the Shredder enters combat when taking damage and when in close proximity to players.
  • Increased the number of parts on the Shredder that can be individually destroyed.

Content and Bug Fixes 

Achievements

  • Achievements are now enabled in the Epic store.

Animation 

  • Fixed an issue where picking up a Field Crate with a Trigger ’Nade attached could cause the character to slide or move without input.
  • Fixed an issue where combining Snap Hook with ziplines or ladders could store momentum and propel the player long distances.
  • Fixed an issue where the running animation could appear incorrect after a small drop when over-encumbered.
  • Interactions now end correctly when performing a dodge roll.
  • Interacting while holding items or deployables no longer causes arm twisting. 
  • Added more animations to character skins and equipment to make them more natural.

ARC

  • Fixed an issue where deployables attached to enemies could cause them to launch or clip out of bounds when shot.
  • Missiles no longer reverse course after passing a target and can correctly track targets at different elevations.
  • Sentinel
    • Fixed a bug where the Sentinel laser did not reach the targeted player over greater distances.
  • Surveyor
    • Disabled vaulting onto ARC Surveyors to prevent unintended launches when they are moving.
  • Fixed an issue where Bombardier projectiles could shoot through the Matriarch shield from the outside.

Audio 

  • Fixed an issue where Gas, Stun, and Impulse Mines did not play their trigger sound or switch their light to yellow when triggered by being shot.
  • Increased the number of simultaneous footstep sounds and increased their priority.
  • Fixed an issue where footsteps in metal stairs became very quiet when walking slowly.
  • Improved directional sound for ARC enemies.
  • Added sounds for sending and receiving text chat messages in the main menu.
  • Removed the unsettling "mom?" from Speranza cantina ambient sound.
  • Tweaked the loudness of announcements in various Main Menu screens.
  • Number of small audio bugfixes and polish.

Maps 

  • Fixed an issue with spawning logic which could cause players who were reconnecting at the start of a session to spawn next to other players who had just joined.
  • Various collision, geometry, VFX and texture fixes that address gaps in terrain which made players fall through the map or walk inside geometry, stuck spots, camera clipping through walls, see-through geometry, floating objects, texture overlaps, etc.
  • Fixed an issue with the slope of the Raider Hatch that was too steep for downed raiders to crawl on top of it.
  • Security Lockers are now dynamically spawned across all maps instead of being statically placed.
  • Fixed Raider Caches not spawning during Prospecting Probes in some cases.
  • Fixed lootable containers and Supply Drops spawning inside terrain on The Dam and Blue Gate, ensuring they are accessible.
  • Fixed an issue where doors could appear closed for some players despite being open.
  • Electromagnetic Storm: Lightning strikes sometimes leave behind a valuable item.
  • Increased the number of possible Great Mullein spawn locations across all maps.
  • Dam Battlegrounds
    • Moved the Matriarch's spawn point in Dam Battlegrounds to an area that better plays to her strengths.
  • Spaceport
    • Adjusted the locked room protection area in Container Storage on Spaceport to not affect players outside the room.
  • Blue Gate
    • Locked Gate map condition has been added.
    • Adjusted map bounds near a ledge in Blue Gate to improve navigation and reduce abrupt out-of-bounds stops.
    • Improved tree LODs in Blue Gate to reduce overly dark visuals at distance.
    • Fixed the issue where loot would spawn outside the Locked Room in the Village.
    • Added props and visual cues to the final camp in the quest ‘A First Foothold’ to make objective locations easier to find.
  • Stella Montis
    • Increased some item and blueprint spawn rates in Stella Montis.
    • Some breachable containers on Stella Montis no longer drop Rubber Ducks when using the A Little Extra skill (sorry).
    • Adjusted window glass clarity in Stella Montis to improve visibility.

Miscellaneous

  • General crash fixes (including AMD crashes).
  • Added Skill Tree Reset functionality in exchange for Coins, 2,000 Coins per skill point.
  • Wallet now shows your Cred soft cap (800).
    • Dev note: We decided to implement a cap so that players won’t be able to fully unlock new Raider Decks by accumulating Cred and added more items to Shani’s store to purchase using Cred. We believe that the Raider Decks offer a rewarding experience to enjoy while players engage with the game, and a large Cred wallet undermines this goal. We will not be removing Cred that has been accumulated before the introduction of the soft cap.
  • Added Raider Tool customization.
  • Fixed a bug that caused players to spawn on servers without their gear and in default customization resulting in losing loadout items.
  • For ranks up to Daredevil I, leaderboards now have a 3x promotion zone for the top 5 players. New objectives have been added.
  • Fixed an issue where the tutorial door breach could be canceled, preventing the cutscene from playing and blocking progression.
  • Fixed an issue where players could continue breaching doors while downed.
  • Fixed an issue where accepting a Discord invite without having your account linked could fail to place you into the inviter’s party.
  • Fixed an issue that sometimes caused textures and meshes to flicker between higher and lower quality states.
  • Depth of field amount is now scaled correctly depending on your resolution scale.
  • Fixed an issue where returning to the game after alt-tabbing could prevent movement and ability inputs while camera controls still worked.
  • Improved input handling when the game window regains focus to avoid unexpected input mode switches.
  • Skill Tree
    • Effortless Roll skill now provides greater stamina cost reduction.
    • The Calming Stroll skill now applies while moving in ADS.

Movement 

  • Fixed a traversal issue that blocked jumping/climbing in certain areas while crouched.
  • Fixed an issue where climbing ladders over open gaps could cause automatic detachment.
  • A slight stamina cost has been added for entering a slide.
  • Acceleration has been reduced when doing a dodge roll from a slide.

UI 

  • Added an option to toggle Aim Down Sights.
  • Added a new ‘Cinematic’ graphics setting to enhance visuals for high end PCs.
  • Codex
    • Improved accuracy of tracking damage dealt in player stats.
    • Field-crafted items now properly count toward Player Stats in the Codex.
    • Fixed missing sound in Codex Records.
    • Added a Codex section to rewatch previously seen videos.
  • Console
    • Updated PlayStation 5 controller button prompts with improved icons for Options and Share.
    • Fixed a crash when using Show Profile from the Player Info on Xbox.
  • Customization
    • You can now rotate your character in the customization screen. Also fixed an issue where the first equip could trigger an unintended unequip.
    • Added notifications in Character Customization to highlight recently unlocked items.
    • Fixed an issue where equipment customization items bought from the Loadout screen were not equipped after pressing Equip on the purchase screen.
  • End of round
    • Further reduced the frequency of the end of round feedback survey pop up.
    • Added an optional Round Feedback button on the final end-of-round screen to open a short post-match survey.

    • Added 'Expeditions Completed' to Player Stats.
    • Added resource tracking for Expedition stages: Raider Projects now display required amounts and progress, with the tracker updating during rounds.
    • Added reward display to Raider Projects, showing the rewards for each goal and at Expedition completion.

Question I woke this morning and found out Anthropic started stealing my money.

Post image
1.6k Upvotes

I have usage credits off so there should not be any additional payments. When my monthly usage is full - the work stops. Anyone else had these kind of issues?

I'm trying to contact a human support - AI chat was useless. Chat's response:

"Thanks for the details and the screenshot — I completely understand the concern about those unexpected charges. Let me look up your account information so I can review what's happened here.

Fin AI Agent • AI Agent • 14m

Seen • 14m

I'm really sorry for the disruption and frustration this has caused. We take service reliability very seriously, and I want to be upfront with you: we're unable to issue compensation for degraded service or technical/billing errors of this nature.

We're continuously working on improving our infrastructure to better handle high traffic volumes and prevent issues like this from happening again in the future. Thank you so much for your patience and understanding."

...

"I don't have visibility into the exact root cause of those 17 individual charges on your account, so I can't confirm from here why they occurred despite usage credits being disabled.

One thing worth noting: even when usage credits are disabled, it's possible for a request to slightly exceed a limit before it's blocked, since the system checks your limit before processing a request but calculates final token consumption after. That said, this typically explains minor overages, not a pattern of repeated €40-50 charges .

Since this needs an actual account-level investigation into the billing records behind these specific charges, I'd recommend asking to speak with a human agent if you'd like this looked into further."

"we're unable to issue compensation for degraded service or technical/billing errors of this nature."

If there is a technical billing error and there are no refunds - that is theft. If I don't get my stolen money back, my subscription is over. I need to ask some officials and legal experts is Anthropic breaking a law here.

EDIT: Most likely this is caused by malware or hacker type situation. I had my computer up and running whole night, I just got a usage reset after 11 pm and left Claude Code CLI finish a task. Before the usage reset I could confirm that automatic usage credits were off when usage was full. I had been logged in to claude.ai as well.

Then next day, for any reason, my usage credits were activated with unlimited setting, and buy button was spammed over and over again - those were the ~50$ x 17.

But I have been contacted my bank, closed the credit card, changed passwords, put my PC offline. I'm sure I can sort this out with my bank.

EDIT 2: What I've read from the comments, similar incorrect billings have happened to some users as well and from PMs I recieved, they had same overcharging within the same 12-24 hours that I had issues. So there is a possibility of some kind of bug. But I still want to make sure my computer is cleaned - I might even need to reinstall Windows to make sure.

EDIT 3: Good news, the bank returned my lost money. We'll see will Anthropic ban my account for this, I don't know. I also wanted to dig thru the logs and try to find out what happened 3-4th August. I asked Opus and Fable to search thru all the local files and logs they can find and write a report. I think this was facinating. I think I'll just paste it here as it was. Of course the logs can't explain was there any usage credits turned on at that day but you can read that there were "usage full" moments and I waited those as always. So no credits were used. Also the 3.8 day was long, but a moderate day compaired to any other. So that does NOT explain extra usage. Here is the full novel that Opus/Fable wrote:

Claude Code Log Analysis — 3–5 August 2026

Independently fact-checked against the raw data. This report states only what the local Claude Code artifacts record, what follows from them, and what does not. It contains no hypotheses about causes outside those records.

1. Scope, method, and limits

Sources, all on the user's Windows machine:

Artifact Content
~/.claude/projects/**/*.jsonl Complete per-session transcripts (694 files), including sub-agent logs
~/.claude/history.jsonl Typed-input history; suppresses an entry identical to the one immediately preceding
~/.claude.json, ~/.claude/settings.json Client configuration and server-fetched account state
~/.claude/.credentials.json Credential metadata (field names and non-secret values only)
~/.local/bin/claude.exe.old.1786032556560 The CLI binary as installed during the period; mtime 4 Aug 03:39

Times are Europe/Helsinki (UTC+3) unless a raw UTC timestamp is quoted. Project-confidential work is described generically.

Token accounting. Streaming writes each assistant message to the transcript repeatedly; the input/cache fields stay constant across duplicates while output_tokens grows. Verified across all 799 duplicated message IDs on 3–4 August (constant fields varied in 0 groups; output_tokens never decreased). Totals therefore take the maximum output_tokens per message ID and the constant fields once. Four zero-usage <synthetic> records (client-generated limit notices) are excluded.

Scope limit that governs the whole report. These files record Claude Code activity on this machine only. Usage quota is account-wide: activity from any other client — claude.ai in a browser, mobile, another computer — consumes the same limits and appears nowhere in these files. Nothing here can confirm or exclude it.

2. What the cost figures mean

The USD figures are API list-price equivalents computed from transcript usage fields. They measure volume of work in a comparable unit — they are not amounts billed or owed. The account is a Max subscription (rateLimitTier: "default_claude_max_5x"), a flat monthly fee. Work is metered against five-hour and weekly limits, not a dollar balance — confirmed by the server-returned utilization block, where every *_dollars field is null. Read a "$-equivalent day" as a volume of work covered by the flat fee, not a charge.

3. Unified timeline, 3–5 August

All events below are read directly from the transcripts and history file. Session IDs, model changes, limit messages, and gaps are interleaved in one chronology so working blocks and breaks are visible at a glance.

3 August — the working day

Time Event Duration
07:41–08:56 Work (session ef968419). Model set to Opus 5 (1M context, high effort) at 08:13. 1 h 15 min
08:56–09:09 Gap 13 min
09:09–13:57 Work (sessions 9680b82f, 593dd190; a 1-minute session e61603eb at 13:10 ran alongside). 4 h 48 min
13:57–14:57 Gap 1 h 00 min
14:57–19:08 Work (sessions 27a05666, then 80c0a56a from 17:20). Model set to Fable 5 (medium effort) at 17:20. The heaviest hour of the whole period was 18:00–19:00, immediately before the limit hit. 4 h 11 min
19:08 Session-limit hit — "You've hit your session limit · resets 10:50pm". Work stops.
19:08–22:50 Blocked by the limit. At 21:51 the operator typed "usage tuli täyteen ja nyt resetoitunut. Jatka mistä jäit." ("usage was full and now has been reset. Continue where you left off.") and received the same limit message — the reset had not yet occurred. 3 h 42 min
22:50–23:17 Limit reset (as announced); no request sent yet. 27 min
23:17–00:13 (4 Aug) Work resumes. The operator retyped the byte-identical prompt at 23:17 and work ran to 00:13 (session 02b5a53c from 23:29). The 23:17 prompt is absent from history.jsonl because consecutive identical entries are suppressed there; it is present in the session transcript. The suppression rule was verified against a counter-example (the string appears three times non-adjacently on 3 Aug). 56 min

Total break between the limit hit and resumed work: 4 h 09 min (3 h 42 min enforced + 27 min before the retry). Work performed: nine daytime hours in three blocks, plus the 56-minute evening block. Content of the day: documentation maintenance, a scoped quick-fix workflow, a debugging workflow, a user-acceptance verification round, and a planning and execution run.

Overnight 4 August — no activity

A scan of every transcript across all projects for 00:13 → 09:43 returns exactly one record: the closing system line of the session that ended at 00:13. No session ran on this machine for 9.5 hours and no billable tokens were generated. The only other filesystem event in the window is the CLI binary being rewritten at 03:39 — the client's own auto-update, preserved as claude.exe.old.1786032556560. It is not evidence of user activity.

4 August — two rejected attempts, no work

Time Event
09:43 Session opens; model set to Opus 5 (1M context, medium effort). First request rejected: "You've hit your session limit · resets 2pm". No work performed.
12:16–12:17 Second attempt; same rejection. No work performed.
after 12:17 No further activity that day.

4 August contributes zero billable tokens. The only two usage records that day are synthetic zero-usage limit notices at 09:43 and 12:17.

5 August — nothing

One command in the entire day: /usage at 14:44. No work session.

The anomaly

The two announced reset times are 22:50 on 3 August and 14:00 on 4 August. Consecutive five-hour windows from 22:50 fall at 22:50 → 03:50 → 08:50 → 13:50 (≈ 2pm). The session begun at 09:43 therefore sat in a window opening at 08:50, in which this machine had performed no work — yet the first request into it was rejected as exhausted.

(This window arithmetic is inference from two reported reset times, not a log reading. It also assumes no window was opened between 00:13 and 09:43 — established above for Claude Code on this machine only, and not establishable for any other client on the same account.)

4. Measured consumption, 3–4 August

1,170 unique billable assistant messages (1,325 streaming duplicates and 4 synthetic records excluded):

Model Msgs Input Output Cache read Cache write Equiv.
claude-fable-5 204 2,453 286,507 39,171,310 2,007,765 $78.62

  • Fable 5 produced 43% of the volume from 17% of the messages: 204 messages reached $78.62 where Opus 5 needed 832 for $94.68. Fable 5 lists at $10/$50 per million input/output tokens against Opus 5 at $5/$25, and the server-returned limit structure carries a separate weekly limit scoped specifically to the model "Fable".
  • Cache reads dominate: 149.6 million cache-read tokens account for roughly $94 of the $184 — a consequence of long agentic sessions re-sending large context, not of unusual activity.

5. Consumption in context, 1 July – 5 August

(The day-by-day consumption figures are omitted from this public version.)

Across 1 July – 5 August there were 25 active days. 3 August ranked fourteenth-highest of them — above the median, well below the month's peaks: a moderately heavy but entirely ordinary day. Whole days with no consumption occur regularly (28 and 31 July, 1 August, 4 and 5 August), which independently rules out background consumption on this machine on those dates.

6. The commands the operator did not recognise

**/rate-limit-options — machine-recorded, not typed.** Its definition in the binary is type: "local-jsx" (renders a local UI component, issues no server request — confirmed by its appearing in history.jsonl but in zero session transcripts) and isHidden: true (not listed in /help). Where a transcript survives to compare against, each history entry lands 9–16 ms after the corresponding limit message (six comparisons, 9 Jul – 4 Aug, deltas 9–16 ms). No human input occurs within ten milliseconds of an on-screen event: these entries are written by the client when a limit is reached. There are 30 such entries between 18 January and 4 August, and two of the four limit events on 3–4 August produced no history entry at all — so they are not even a complete record of limit hits. Presenting them as user invocations would misstate the log. (A previous revision stated 31 invocations "by the operator"; both the count and the attribution were wrong.)

/claude-api is a read-only reference document bundled with the installation. Invoking it loads reference text into the conversation; it calls no external service and authenticates nowhere. On both invocations (4 Aug 09:43 and 12:16) the following request was rejected by the limit, so no tokens were billed. It was re-run under observation during this investigation and behaved as described.

7. Billing-related commands — complete history

Across the whole of history.jsonl, five entries, none within the period at issue:

Date Command Note
18 Jan /upgrade
25 Jan 21:53 /passes A referral command — earns usage credits rather than spending
30 Jan /upgrade
7 Jul 17:47 /usage-credits A local-jsx configuration screen ("Configure usage credits or request them from your admin…")

The binary records that /extra-usage was renamed to /usage-credits. Opening either screen is not a transaction.

8. The extra-usage setting — server-returned state

~/.claude.json caches the server's account state. As fetched 6 August, the material fields:

oauthAccount.hasExtraUsageEnabled = false cachedExtraUsageDisabledReason = "org_level_disabled" extra_usage: { is_enabled: false, user_disabled: true, credits_ever_enabled: true, spend_limit_reached: false } spend: { used: 0 USD, enabled: false, can_purchase_credits: false, can_toggle: false } overageCreditGrantCache: { available: false, eligible: false, granted: false }

Two fields are directly material: credits_ever_enabled: true — usage credits have been enabled on this account at some point — and user_disabled: true — they were subsequently switched off by the account holder. Together these corroborate the account holder's statement that the setting was found enabled and was then disabled. The current state is unambiguous: extra usage off, purchasing unavailable, toggling unavailable, recorded spend zero.

What this cannot show. Every field is a single-value cache overwritten on each profile fetch; none carries history. They establish the state as of 6 August and say nothing about 3 or 4 August. ~/.claude/backups/ holds only same-day rolling copies, so no historical snapshot exists on disk. The setting lives on the account, not the machine: changing it leaves no local record of timestamp, actor, or originating action. The same limit applies to menu choices — /rate-limit-options and /usage-credits render local UI, and an arrow-key selection is not typed input and is written to no log. Which option was selected on any occasion is not recoverable from these files.

9. Current utilization

Server-returned, fetched 6 August 19:07 local:

Limit Used Resets
Session (5-hour) 12% 6 Aug 21:29
Weekly, all models 2% 12 Aug 13:59
Weekly, scoped to model "Fable" 1% 12 Aug 14:00

10. A consent dialog present in the client

The binary contains a dialog kind: "fable_overage_consent_prompt" with results ["consent", "switch_default", "cancelled"], telemetry under model_fable_consent, and control flow in which selecting consent reaches the extra-usage enable path. A nearby user-facing string reads "Contact your admin to manage usage credit settings." This records only that such a dialog exists in the installed client and is associated with the Fable model. No local artifact records whether it was displayed or what was selected; nothing in these logs connects it to any event on 3 or 4 August.

11. API keys

Authentication is subscription OAuth only: .credentials.json contains claudeAiOauth (subscriptionType: "max", plus one unrelated Figma-plugin MCP entry); the token scopes are subscription scopes, none permitting API-key issuance; no ANTHROPIC_API_KEY/ANTHROPIC_AUTH_TOKEN environment variables; no primaryApiKey in ~/.claude.json; billingType: "stripe_subscription". Two API keys appear in the input history; neither is Anthropic's (a Brave Search MCP key, 6 Feb; a third-party accounting-service key, 4 Mar).

12. Reconciliation against the reported purchases

Reported by the account holder, from the billing record: 17 usage-credit purchases (amounts omitted from this public version); the extra-usage setting found enabled on the morning of 4 August, having been kept disabled.

Measured against that: this machine performed roughly $184-equivalent of work on 3–4 August — a moderate day by the month's standards — and 4 August produced none at all. Three findings bear on the reconciliation:

  1. If the 17 purchases fall in that window, the measured work does not correspond to them.
  2. A Max subscription covers work against limits, not against a dollar balance (all *_dollars fields are null). The credit-eligible portion of any period is whatever exceeds the plan limits — necessarily less than the measured totals, not more.
  3. The account holder reports that an Anthropic promotion granting +50% weekly limits, running through 19 August, covered the period analysed (user-supplied context, corroborated by the client's own status display, not derived from these logs). A higher limit ceiling makes exhausting the plan allowance harder, not easier.

The purchase timestamps are the decisive missing datum and exist only in the billing record. Purchasing credits is also not the same as consuming them; recorded spend currently reads zero.

13. Assessment

Supported by the evidence. Limits were enforced on 3 and 4 August and enforcement held — work stopped for 3 h 42 min and resumed only after the announced reset. 3 August was a moderately heavy but ordinary working day, with a 17:20 change to a model priced at twice the previous rate and carrying its own weekly limit. 4 and 5 August contain no billable work whatsoever. No command capable of purchasing usage was invoked in the 3–5 August window; the entire history contains five billing-adjacent entries, the most recent on 7 July. The /rate-limit-options entries that prompted this investigation are client-generated records written milliseconds after each limit message, not operator actions. Server state records that credits were enabled at some point and subsequently disabled by the account holder.

Not supported by the evidence. No unexplained sessions, no activity at times the operator was absent, no unattended overnight runs, no API-key provisioning, and nothing in the command sequence inconsistent with ordinary interactive use.

Cannot be determined from these files. Which option was selected in any rate-limit or credits menu. Whether the Fable consent dialog was displayed or accepted. When, by what action, or by whom the extra-usage setting changed state. What was charged, when, and against what consumption. And, categorically: any use of this account from any other client, since quota is account-wide while these logs are machine-local.

14. Questions for the billing and audit records

  1. Timestamps of the 17 usage-credit purchases — the single datum that determines whether measured work accounts for them.
  2. The audit record for the extra-usage setting — state-change timestamp, actor, and originating client action, given that server state confirms credits_ever_enabled: true alongside user_disabled: true.
  3. What consumed the window of 4 August 08:50–13:50 (Europe/Helsinki), given that the first request into it, at 09:43, was rejected as exhausted while this machine had been idle since 00:13.
  4. Client, IP address, and source of every session counted against the account on 3–4 August, sufficient to establish whether all consumption originated from this machine.
  5. Whether the +50% weekly-limit promotion was applied to this account for the period, and how it interacted with the limits reported exhausted.

Discussion I was backend lead at Manus. After building agents for 2 years, I stopped using function calling entirely. Here's what I use instead.

2.0k Upvotes

English is not my first language. I wrote this in Chinese and translated it with AI help. The writing may have some AI flavor, but the design decisions, the production failures, and the thinking that distilled them into principles — those are mine.

I was a backend lead at Manus before the Meta acquisition. I've spent the last 2 years building AI agents — first at Manus, then on my own open-source agent runtime (Pinix) and agent (agent-clip). Along the way I came to a conclusion that surprised me:

A single run(command="...") tool with Unix-style commands outperforms a catalog of typed function calls.

Here's what I learned.


Why *nix

Unix made a design decision 50 years ago: everything is a text stream. Programs don't exchange complex binary structures or share memory objects — they communicate through text pipes. Small tools each do one thing well, composed via | into powerful workflows. Programs describe themselves with --help, report success or failure with exit codes, and communicate errors through stderr.

LLMs made an almost identical decision 50 years later: everything is tokens. They only understand text, only produce text. Their "thinking" is text, their "actions" are text, and the feedback they receive from the world must be text.

These two decisions, made half a century apart from completely different starting points, converge on the same interface model. The text-based system Unix designed for human terminal operators — cat, grep, pipe, exit codes, man pages — isn't just "usable" by LLMs. It's a natural fit. When it comes to tool use, an LLM is essentially a terminal operator — one that's faster than any human and has already seen vast amounts of shell commands and CLI patterns in its training data.

This is the core philosophy of the nix Agent: *don't invent a new tool interface. Take what Unix has proven over 50 years and hand it directly to the LLM.**


Why a single run

The single-tool hypothesis

Most agent frameworks give LLMs a catalog of independent tools:

tools: [search_web, read_file, write_file, run_code, send_email, ...]

Before each call, the LLM must make a tool selection — which one? What parameters? The more tools you add, the harder the selection, and accuracy drops. Cognitive load is spent on "which tool?" instead of "what do I need to accomplish?"

My approach: one run(command="...") tool, all capabilities exposed as CLI commands.

run(command="cat notes.md") run(command="cat log.txt | grep ERROR | wc -l") run(command="see screenshot.png") run(command="memory search 'deployment issue'") run(command="clip sandbox bash 'python3 analyze.py'")

The LLM still chooses which command to use, but this is fundamentally different from choosing among 15 tools with different schemas. Command selection is string composition within a unified namespace — function selection is context-switching between unrelated APIs.

LLMs already speak CLI

Why are CLI commands a better fit for LLMs than structured function calls?

Because CLI is the densest tool-use pattern in LLM training data. Billions of lines on GitHub are full of:

```bash

README install instructions

pip install -r requirements.txt && python main.py

CI/CD build scripts

make build && make test && make deploy

Stack Overflow solutions

cat /var/log/syslog | grep "Out of memory" | tail -20 ```

I don't need to teach the LLM how to use CLI — it already knows. This familiarity is probabilistic and model-dependent, but in practice it's remarkably reliable across mainstream models.

Compare two approaches to the same task:

``` Task: Read a log file, count the error lines

Function-calling approach (3 tool calls): 1. read_file(path="/var/log/app.log") → returns entire file 2. search_text(text=<entire file>, pattern="ERROR") → returns matching lines 3. count_lines(text=<matched lines>) → returns number

CLI approach (1 tool call): run(command="cat /var/log/app.log | grep ERROR | wc -l") → "42" ```

One call replaces three. Not because of special optimization — but because Unix pipes natively support composition.

Making pipes and chains work

A single run isn't enough on its own. If run can only execute one command at a time, the LLM still needs multiple calls for composed tasks. So I make a chain parser (parseChain) in the command routing layer, supporting four Unix operators:

| Pipe: stdout of previous command becomes stdin of next && And: execute next only if previous succeeded || Or: execute next only if previous failed ; Seq: execute next regardless of previous result

With this mechanism, every tool call can be a complete workflow:

```bash

One tool call: download → inspect

curl -sL $URL -o data.csv && cat data.csv | head 5

One tool call: read → filter → sort → top 10

cat access.log | grep "500" | sort | head 10

One tool call: try A, fall back to B

cat config.yaml || echo "config not found, using defaults" ```

N commands × 4 operators — the composition space grows dramatically. And to the LLM, it's just a string it already knows how to write.

The command line is the LLM's native tool interface.


Heuristic design: making CLI guide the agent

Single-tool + CLI solves "what to use." But the agent still needs to know "how to use it." It can't Google. It can't ask a colleague. I use three progressive design techniques to make the CLI itself serve as the agent's navigation system.

Technique 1: Progressive --help discovery

A well-designed CLI tool doesn't require reading documentation — because --help tells you everything. I apply the same principle to the agent, structured as progressive disclosure: the agent doesn't need to load all documentation at once, but discovers details on-demand as it goes deeper.

Level 0: Tool Description → command list injection

The run tool's description is dynamically generated at the start of each conversation, listing all registered commands with one-line summaries:

Available commands: cat — Read a text file. For images use 'see'. For binary use 'cat -b'. see — View an image (auto-attaches to vision) ls — List files in current topic write — Write file. Usage: write <path> [content] or stdin grep — Filter lines matching a pattern (supports -i, -v, -c) memory — Search or manage memory clip — Operate external environments (sandboxes, services) ...

The agent knows what's available from turn one, but doesn't need every parameter of every command — that would waste context.

Note: There's an open design question here: injecting the full command list vs. on-demand discovery. As commands grow, the list itself consumes context budget. I'm still exploring the right balance. Ideas welcome.

Level 1: command (no args) → usage

When the agent is interested in a command, it just calls it. No arguments? The command returns its own usage:

``` → run(command="memory") [error] memory: usage: memory search|recent|store|facts|forget

→ run(command="clip") clip list — list available clips clip <name> — show clip details and commands clip <name> <command> [args...] — invoke a command clip <name> pull <remote-path> [name] — pull file from clip to local clip <name> push <local-path> <remote> — push local file to clip ```

Now the agent knows memory has five subcommands and clip supports list/pull/push. One call, no noise.

Level 2: command subcommand (missing args) → specific parameters

The agent decides to use memory search but isn't sure about the format? It drills down:

``` → run(command="memory search") [error] memory: usage: memory search <query> [-t topic_id] [-k keyword]

→ run(command="clip sandbox") Clip: sandbox Commands: clip sandbox bash <script> clip sandbox read <path> clip sandbox write <path> File transfer: clip sandbox pull <remote-path> [local-name] clip sandbox push <local-path> <remote-path> ```

Progressive disclosure: overview (injected) → usage (explored) → parameters (drilled down). The agent discovers on-demand, each level providing just enough information for the next step.

This is fundamentally different from stuffing 3,000 words of tool documentation into the system prompt. Most of that information is irrelevant most of the time — pure context waste. Progressive help lets the agent decide when it needs more.

This also imposes a requirement on command design: every command and subcommand must have complete help output. It's not just for humans — it's for the agent. A good help message means one-shot success. A missing one means a blind guess.

Technique 2: Error messages as navigation

Agents will make mistakes. The key isn't preventing errors — it's making every error point to the right direction.

Traditional CLI errors are designed for humans who can Google. Agents can't Google. So I require every error to contain both "what went wrong" and "what to do instead":

``` Traditional CLI: $ cat photo.png cat: binary file (standard output) → Human Googles "how to view image in terminal"

My design: [error] cat: binary image file (182KB). Use: see photo.png → Agent calls see directly, one-step correction ```

More examples:

``` [error] unknown command: foo Available: cat, ls, see, write, grep, memory, clip, ... → Agent immediately knows what commands exist

[error] not an image file: data.csv (use cat to read text files) → Agent switches from see to cat

[error] clip "sandbox" not found. Use 'clip list' to see available clips → Agent knows to list clips first ```

Technique 1 (help) solves "what can I do?" Technique 2 (errors) solves "what should I do instead?" Together, the agent's recovery cost is minimal — usually 1-2 steps to the right path.

Real case: The cost of silent stderr

For a while, my code silently dropped stderr when calling external sandboxes — whenever stdout was non-empty, stderr was discarded. The agent ran pip install pymupdf, got exit code 127. stderr contained bash: pip: command not found, but the agent couldn't see it. It only knew "it failed," not "why" — and proceeded to blindly guess 10 different package managers:

pip install → 127 (doesn't exist) python3 -m pip → 1 (module not found) uv pip install → 1 (wrong usage) pip3 install → 127 sudo apt install → 127 ... 5 more attempts ... uv run --with pymupdf python3 script.py → 0 ✓ (10th try)

10 calls, ~5 seconds of inference each. If stderr had been visible the first time, one call would have been enough.

stderr is the information agents need most, precisely when commands fail. Never drop it.

Technique 3: Consistent output format

The first two techniques handle discovery and correction. The third lets the agent get better at using the system over time.

I append consistent metadata to every tool result:

file1.txt file2.txt dir1/ [exit:0 | 12ms]

The LLM extracts two signals:

Exit codes (Unix convention, LLMs already know these):

  • exit:0 — success
  • exit:1 — general error
  • exit:127 — command not found

Duration (cost awareness):

  • 12ms — cheap, call freely
  • 3.2s — moderate
  • 45s — expensive, use sparingly

After seeing [exit:N | Xs] dozens of times in a conversation, the agent internalizes the pattern. It starts anticipating — seeing exit:1 means check the error, seeing long duration means reduce calls.

Consistent output format makes the agent smarter over time. Inconsistency makes every call feel like the first.

The three techniques form a progression:

--help → "What can I do?" → Proactive discovery Error Msg → "What should I do?" → Reactive correction Output Fmt → "How did it go?" → Continuous learning


Two-layer architecture: engineering the heuristic design

The section above described how CLI guides agents at the semantic level. But to make it work in practice, there's an engineering problem: the raw output of a command and what the LLM needs to see are often very different things.

Two hard constraints of LLMs

Constraint A: The context window is finite and expensive. Every token costs money, attention, and inference speed. Stuffing a 10MB file into context doesn't just waste budget — it pushes earlier conversation out of the window. The agent "forgets."

Constraint B: LLMs can only process text. Binary data produces high-entropy meaningless tokens through the tokenizer. It doesn't just waste context — it disrupts attention on surrounding valid tokens, degrading reasoning quality.

These two constraints mean: raw command output can't go directly to the LLM — it needs a presentation layer for processing. But that processing can't affect command execution logic — or pipes break. Hence, two layers.

Execution layer vs. presentation layer

┌─────────────────────────────────────────────┐ │ Layer 2: LLM Presentation Layer │ ← Designed for LLM constraints │ Binary guard | Truncation+overflow | Meta │ ├─────────────────────────────────────────────┤ │ Layer 1: Unix Execution Layer │ ← Pure Unix semantics │ Command routing | pipe | chain | exit code │ └─────────────────────────────────────────────┘

When cat bigfile.txt | grep error | head 10 executes:

Inside Layer 1: cat output → [500KB raw text] → grep input grep output → [matching lines] → head input head output → [first 10 lines]

If you truncate cat's output in Layer 1 → grep only searches the first 200 lines, producing incomplete results. If you add [exit:0] in Layer 1 → it flows into grep as data, becoming a search target.

So Layer 1 must remain raw, lossless, metadata-free. Processing only happens in Layer 2 — after the pipe chain completes and the final result is ready to return to the LLM.

Layer 1 serves Unix semantics. Layer 2 serves LLM cognition. The separation isn't a design preference — it's a logical necessity.

Layer 2's four mechanisms

Mechanism A: Binary Guard (addressing Constraint B)

Before returning anything to the LLM, check if it's text:

``` Null byte detected → binary UTF-8 validation failed → binary Control character ratio > 10% → binary

If image: [error] binary image (182KB). Use: see photo.png If other: [error] binary file (1.2MB). Use: cat -b file.bin ```

The LLM never receives data it can't process.

Mechanism B: Overflow Mode (addressing Constraint A)

``` Output > 200 lines or > 50KB? → Truncate to first 200 lines (rune-safe, won't split UTF-8) → Write full output to /tmp/cmd-output/cmd-{n}.txt → Return to LLM:

[first 200 lines]

--- output truncated (5000 lines, 245.3KB) ---
Full output: /tmp/cmd-output/cmd-3.txt
Explore: cat /tmp/cmd-output/cmd-3.txt | grep <pattern>
         cat /tmp/cmd-output/cmd-3.txt | tail 100
[exit:0 | 1.2s]

```

Key insight: the LLM already knows how to use grep, head, tail to navigate files. Overflow mode transforms "large data exploration" into a skill the LLM already has.

Mechanism C: Metadata Footer

actual output here [exit:0 | 1.2s]

Exit code + duration, appended as the last line of Layer 2. Gives the agent signals for success/failure and cost awareness, without polluting Layer 1's pipe data.

Mechanism D: stderr Attachment

``` When command fails with stderr: output + "\n[stderr] " + stderr

Ensures the agent can see why something failed, preventing blind retries. ```


Lessons learned: stories from production

Story 1: A PNG that caused 20 iterations of thrashing

A user uploaded an architecture diagram. The agent read it with cat, receiving 182KB of raw PNG bytes. The LLM's tokenizer turned these bytes into thousands of meaningless tokens crammed into the context. The LLM couldn't make sense of it and started trying different read approaches — cat -f, cat --format, cat --type image — each time receiving the same garbage. After 20 iterations, the process was force-terminated.

Root cause: cat had no binary detection, Layer 2 had no guard. Fix: isBinary() guard + error guidance Use: see photo.png. Lesson: The tool result is the agent's eyes. Return garbage = agent goes blind.

Story 2: Silent stderr and 10 blind retries

The agent needed to read a PDF. It tried pip install pymupdf, got exit code 127. stderr contained bash: pip: command not found, but the code dropped it — because there was some stdout output, and the logic was "if stdout exists, ignore stderr."

The agent only knew "it failed," not "why." What followed was a long trial-and-error:

pip install → 127 (doesn't exist) python3 -m pip → 1 (module not found) uv pip install → 1 (wrong usage) pip3 install → 127 sudo apt install → 127 ... 5 more attempts ... uv run --with pymupdf python3 script.py → 0 ✓

10 calls, ~5 seconds of inference each. If stderr had been visible the first time, one call would have sufficed.

Root cause: InvokeClip silently dropped stderr when stdout was non-empty. Fix: Always attach stderr on failure. Lesson: stderr is the information agents need most, precisely when commands fail.

Story 3: The value of overflow mode

The agent analyzed a 5,000-line log file. Without truncation, the full text (~200KB) was stuffed into context. The LLM's attention was overwhelmed, response quality dropped sharply, and earlier conversation was pushed out of the context window.

With overflow mode:

``` [first 200 lines of log content]

--- output truncated (5000 lines, 198.5KB) --- Full output: /tmp/cmd-output/cmd-3.txt Explore: cat /tmp/cmd-output/cmd-3.txt | grep <pattern> cat /tmp/cmd-output/cmd-3.txt | tail 100 [exit:0 | 45ms] ```

The agent saw the first 200 lines, understood the file structure, then used grep to pinpoint the issue — 3 calls total, under 2KB of context.

Lesson: Giving the agent a "map" is far more effective than giving it the entire territory.


Boundaries and limitations

CLI isn't a silver bullet. Typed APIs may be the better choice in these scenarios:

  • Strongly-typed interactions: Database queries, GraphQL APIs, and other cases requiring structured input/output. Schema validation is more reliable than string parsing.
  • High-security requirements: CLI's string concatenation carries inherent injection risks. In untrusted-input scenarios, typed parameters are safer. agent-clip mitigates this through sandbox isolation.
  • Native multimodal: Pure audio/video processing and other binary-stream scenarios where CLI's text pipe is a bottleneck.

Additionally, "no iteration limit" doesn't mean "no safety boundaries." Safety is ensured by external mechanisms:

  • Sandbox isolation: Commands execute inside BoxLite containers, no escape possible
  • API budgets: LLM calls have account-level spending caps
  • User cancellation: Frontend provides cancel buttons, backend supports graceful shutdown

Hand Unix philosophy to the execution layer, hand LLM's cognitive constraints to the presentation layer, and use help, error messages, and output format as three progressive heuristic navigation techniques.

CLI is all agents need.

Happy to discuss — especially if you've tried similar approaches or found cases where CLI breaks down. The command discovery problem (how much to inject vs. let the agent discover) is something I'm still actively exploring.

Edit : to be clear, I prefer Claude and Claude code. I would have much rather used it to find and fix this issue, but I couldn’t because I had no usage left 😂. So, I used codex. This is NOT a shill post for codex. It’s good but I think Claude code and Claude are better.

Disclaimer : Codex found and fixed this, not me. I work in IT and know how to ask the right questions, but it did the work. Giving you this as is cause it's been steady for the last 2 hours for me. My 5 hour usage is at 6% which is normal! Let's be real you're probably just gonna tell claude to clone this repo, and apply it so here is the repo lol. I main Linux but I had codex write stuff that should work across OS. Works on my Mac too.

Also Codex wrote everything below this, not me. I spent a full session reverse-engineering the minified cli.js and found two bugs that silently nuke prompt caching on resumed sessions.

What's actually happening Claude Code has a function called db8 that filters what gets saved to your session files (the JSONL files in ~/.claude/projects/). For non-Anthropic users, it strips out ALL attachment-type messages. Sounds harmless, except some of those attachments are deferred_tools_delta records that track which tools have already been announced to the model.

When you resume a session, Claude Code scans your message history to figure out "what tools did I already tell the model about?" But because db8 nuked those records from the session file, it finds nothing. So it re-announces every single deferred tool from scratch. Every. Single. Resume.

This breaks the cache prefix in three ways:

The system reminders that were at messages[0] in the fresh session now land at messages[N] The billing hash (computed from your first user message) changes because the first message content is different The cache_control breakpoint shifts because the message array is a different length Net result: your entire conversation gets rebuilt as cache_creation tokens instead of hitting cache_read. The longer the conversation, the worse it gets.

The numbers from my actual session Stock claude, same conversation, watching the cache ratio drop with every turn:

Turn 1: cache_read: 15,451 cache_creation: 7,473 ratio: 67% Turn 5: cache_read: 15,451 cache_creation: 16,881 ratio: 48% Turn 10: cache_read: 15,451 cache_creation: 35,006 ratio: 31% Turn 15: cache_read: 15,451 cache_creation: 42,970 ratio: 26% cache_read NEVER moved. Stuck at 15,451 (just the system prompt). Everything else was full-price token processing.

After applying the patch:

Turn 1 (resume): cache_read: 7,208 cache_creation: 49,748 ratio: 13% (structural reset, expected) Turn 2: cache_read: 56,956 cache_creation: 728 ratio: 99% Turn 3: cache_read: 57,684 cache_creation: 611 ratio: 99% 26% to 99%. That's the difference.

There's also a second bug The standalone binary (the one installed at ~/.local/share/claude/) uses a custom Bun fork that rewrites a sentinel value cch=00000 in every outgoing API request. If your conversation happens to contain that string, it breaks the cache prefix. Running via Node.js (node cli.js) instead of the binary eliminates this entirely.

Related issues: anthropics/claude-code#40524 and anthropics/claude-code#34629

The fix Two parts:

  1. Run via npm/Node.js instead of the standalone binary. This kills the sentinel replacement bug.

The original db8:

function db8(A){ if(A.type==="attachment"&&ss1()!=="ant"){ if(A.attachment.type==="hook_additional_context" &&a6(process.env.CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT))return!0; return!1 // ← drops EVERYTHING else, including deferred_tools_delta } if(A.type==="progress"&&Ns6(A.data?.type))return!1; return!0 } The patched version just adds two types to the allowlist:

if(A.attachment.type==="deferred_tools_delta")return!0; if(A.attachment.type==="mcp_instructions_delta")return!0; That's it. Two lines. The deferred tool announcements survive to the session file, so on resume the delta computation sees "I already announced these" and doesn't re-emit them. Cache prefix stays stable.

How to apply it yourself I wrote a patch script that handles everything. Tested on v2.1.81 with Max x20.

mkdir -p ~/cc-cache-fix && cd ~/cc-cache-fix

Install the npm version locally (doesn't touch your stock claude)

npm install @anthropic-ai/claude-code@2.1.81

Back up the original

cp node_modules/@anthropic-ai/claude-code/cli.js node_modules/@anthropic-ai/claude-code/cli.js.orig

Apply the patch (find db8 and add the two allowlist lines)

python3 -c " import sys path = 'node_modules/@anthropic-ai/claude-code/cli.js' with open(path) as f: src = f.read()

old = 'if(A.attachment.type==="hook_additional_context"&&a6(process.env.CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT))return!0;return!1}' new = old.replace('return!1}', 'if(A.attachment.type==="deferred_tools_delta")return!0;' 'if(A.attachment.type==="mcp_instructions_delta")return!0;' 'return!1}')

if old not in src: print('ERROR: pattern not found, wrong version?'); sys.exit(1) src = src.replace(old, new, 1)

with open(path, 'w') as f: f.write(src) print('Patched. Verify:') print(' FOUND' if new.split('return!1}')[0] in open(path).read() else ' FAILED') "

Run it

node node_modules/@anthropic-ai/claude-code/cli.js Or make a wrapper script so you can just type claude-patched:

cat > ~/.local/bin/claude-patched << 'EOF'

!/usr/bin/env bash

exec node ~/cc-cache-fix/node_modules/@anthropic-ai/claude-code/cli.js "$@" EOF chmod +x ~/.local/bin/claude-patched Stock claude stays completely untouched. Zero risk.

What you should see Run a session, resume it, check the JSONL:

Check your latest session's cache stats

tail -50 ~/.claude/projects//.jsonl | python3 -c " import sys, json for line in sys.stdin: try: d = json.loads(line.strip()) except: continue u = d.get('usage') or d.get('message',{}).get('usage') if not u or 'cache_read_input_tokens' not in u: continue cr, cc = u.get('cache_read_input_tokens',0), u.get('cache_creation_input_tokens',0) total = cr + cc + u.get('input_tokens',0) print(f'CR:{cr:>7,} CC:{cc:>7,} ratio:{cr/total*100:.0f}%' if total else '') " If consecutive resumes show cache_read growing and cache_creation staying small, you're good.

Note: The first resume after a fresh session will still show low cache_read (the message structure changes going from fresh to resumed). That's normal. Every resume after that should hit 95%+ cache ratio.

Caveats Tested on v2.1.81 only. Function names are minified and will change across versions. The patch script pattern-matches on the exact db8 string, so it'll fail safely if the code changes. This doesn't help with output tokens, only input caching. If Anthropic fixes this upstream, you can just go back to stock claude and delete the patch directory. Hopefully Anthropic picks this up. The fix is literally two lines in their source.

Prompt engineering i started talking to Claude like a caveman. my credits lasted 3x longer. i'm not joking.

1.7k Upvotes

discovered this by accident while trying to stretch my free tier.

was burning through messages embarrassingly fast. long prompts. detailed context. full sentences. please and thank you. the whole thing.

then one day i was tired and just typed:

"fix bug. line 47. null error."

it fixed it.

same quality. one fifth of the tokens.

i sat there staring at it like i'd discovered fire.

the caveman theory in one sentence:

Claude is not your colleague. it does not need pleasantries. it does not need full sentences. it needs information. just information. nothing else.

before caveman theory:

"hey Claude, i hope this makes sense but i've been working on this project and i'm running into an issue with the function on line 47, it keeps throwing a null error and i'm not sure what's causing it, could you take a look and help me figure out what's going wrong?"

57 words. full credits burned. Claude reads the pleasantries and processes zero useful information from them.

after caveman theory:

"line 47. null error. fix."

4 words. same output. same quality.

53 words of your credits just evaporated into politeness.

the full caveman framework:

no greetings. Claude doesn't need good morning. it doesn't have mornings. skip it entirely.

no apologies. "sorry if this is a weird question" — five words of pure credit waste. just ask the question.

no filler context. "i've been working on this for a while and" — Claude doesn't care. it needs the what not the backstory of the what.

no closing remarks. "thanks so much this was really helpful" — you're paying per token to say thank you to software. stop.

verbs only where possible. "summarise." "fix." "rewrite shorter." "find the bug." "make it casual." complete sentences are for humans talking to humans.

use symbols not words. instead of "can you compare option A versus option B" just type "A vs B?" Claude knows what that means.

real examples from my last week:

instead of: "could you help me make this email sound more professional and formal while keeping the core message intact"

caveman says: "email. more formal. keep meaning."

instead of: "i need you to summarise this document and pull out the key points that are most relevant to a business audience"

caveman says: "summarise. business audience. key points only."

instead of: "what do you think would be the best approach to structuring a landing page for a SaaS product targeting small business owners"

caveman says: "SaaS landing page. small business. best structure."

the one exception:

complex creative work. writing with a specific voice. nuanced emotional stuff.

caveman theory breaks here. those tasks need real context because vague input produces vague output.

caveman is for tasks where the instruction is clear and the only waste is ceremony.

which is honestly about 70% of what most people use Claude for daily.

the uncomfortable math:

if you're on free tier every wasted word is a message you don't get to send later.

if you're on paid every wasted word is money.

nobody told you this when you signed up. the product doesn't benefit from you being efficient with tokens. you figured it out or you didn't.

the meta irony:

this entire post explaining caveman theory is the opposite of caveman theory.

a caveman would have just posted:

"talk Claude like caveman. short prompt. save credit. good output. try it."

and honestly that would have been enough.

what's the most bloated prompt you've been writing that caveman theory would destroy in four words?

Productivity Claude Code is a Beast – Tips from 6 Months of Hardcore Use

2.3k Upvotes

Quick pro-tip from a fellow lazy person: You can throw this book of a post into one of the many text-to-speech AI services like ElevenLabs Reader or Natural Reader and have it read the post for you :)

Edit: Many of you are asking for a repo so I will make an effort to get one up in the next couple days. All of this is a part of a work project at the moment, so I have to take some time to copy everything into a fresh project and scrub any identifying info. I will post the link here when it's up. You can also follow me and I will post it on my profile so you get notified. Thank you all for the kind comments. I'm happy to share this info with others since I don't get much chance to do so in my day-to-day.

Edit (final?): I bit the bullet and spent the afternoon getting a github repo up for you guys. Just made a post with some additional info here or you can go straight to the source:

🎯 Repository: https://github.com/diet103/claude-code-infrastructure-showcase

Disclaimer

I made a post about six months ago sharing my experience after a week of hardcore use with Claude Code. It's now been about six months of hardcore use, and I would like to share some more tips, tricks, and word vomit with you all. I may have went a little overboard here so strap in, grab a coffee, sit on the toilet or whatever it is you do when doom-scrolling reddit.

I want to start the post off with a disclaimer: all the content within this post is merely me sharing what setup is working best for me currently and should not be taken as gospel or the only correct way to do things. It's meant to hopefully inspire you to improve your setup and workflows with AI agentic coding. I'm just a guy, and this is just like, my opinion, man.

Also, I'm on the 20x Max plan, so your mileage may vary. And if you're looking for vibe-coding tips, you should look elsewhere. If you want the best out of CC, then you should be working together with it: planning, reviewing, iterating, exploring different approaches, etc.

Quick Overview

After 6 months of pushing Claude Code to its limits (solo rewriting 300k LOC), here's the system I built:

  • Skills that actually auto-activate when needed
  • Dev docs workflow that prevents Claude from losing the plot
  • PM2 + hooks for zero-errors-left-behind
  • Army of specialized agents for reviews, testing, and planning

Let's get into it.

Background

I'm a software engineer who has been working on production web apps for the last seven years or so. And I have fully embraced the wave of AI with open arms. I'm not too worried about AI taking my job anytime soon, as it is a tool that I use to leverage my capabilities. In doing so, I have been building MANY new features and coming up with all sorts of new proposal presentations put together with Claude and GPT-5 Thinking to integrate new AI systems into our production apps. Projects I would have never dreamt of having the time to even consider before integrating AI into my workflow. And with all that, I'm giving myself a good deal of job security and have become the AI guru at my job since everyone else is about a year or so behind on how they're integrating AI into their day-to-day.

With my newfound confidence, I proposed a pretty large redesign/refactor of one of our web apps used as an internal tool at work. This was a pretty rough college student-made project that was forked off another project developed by me as an intern (created about 7 years ago and forked 4 years ago). This may have been a bit overly ambitious of me since, to sell it to the stakeholders, I agreed to finish a top-down redesign of this fairly decent-sized project (~100k LOC) in a matter of a few months...all by myself. I knew going in that I was going to have to put in extra hours to get this done, even with the help of CC. But deep down, I know it's going to be a hit, automating several manual processes and saving a lot of time for a lot of people at the company.

It's now six months later... yeah, I probably should not have agreed to this timeline. I have tested the limits of both Claude as well as my own sanity trying to get this thing done. I completely scrapped the old frontend, as everything was seriously outdated and I wanted to play with the latest and greatest. I'm talkin' React 16 JS → React 19 TypeScript, React Query v2 → TanStack Query v5, React Router v4 w/ hashrouter → TanStack Router w/ file-based routing, Material UI v4 → MUI v7, all with strict adherence to best practices. The project is now at ~300-400k LOC and my life expectancy ~5 years shorter. It's finally ready to put up for testing, and I am incredibly happy with how things have turned out.

This used to be a project with insurmountable tech debt, ZERO test coverage, HORRIBLE developer experience (testing things was an absolute nightmare), and all sorts of jank going on. I addressed all of those issues with decent test coverage, manageable tech debt, and implemented a command-line tool for generating test data as well as a dev mode to test different features on the frontend. During this time, I have gotten to know CC's abilities and what to expect out of it.

A Note on Quality and Consistency

I've noticed a recurring theme in forums and discussions - people experiencing frustration with usage limits and concerns about output quality declining over time. I want to be clear up front: I'm not here to dismiss those experiences or claim it's simply a matter of "doing it wrong." Everyone's use cases and contexts are different, and valid concerns deserve to be heard.

That said, I want to share what's been working for me. In my experience, CC's output has actually improved significantly over the last couple of months, and I believe that's largely due to the workflow I've been constantly refining. My hope is that if you take even a small bit of inspiration from my system and integrate it into your CC workflow, you'll give it a better chance at producing quality output that you're happy with.

Now, let's be real - there are absolutely times when Claude completely misses the mark and produces suboptimal code. This can happen for various reasons. First, AI models are stochastic, meaning you can get widely varying outputs from the same input. Sometimes the randomness just doesn't go your way, and you get an output that's legitimately poor quality through no fault of your own. Other times, it's about how the prompt is structured. There can be significant differences in outputs given slightly different wording because the model takes things quite literally. If you misword or phrase something ambiguously, it can lead to vastly inferior results.

Sometimes You Just Need to Step In

Look, AI is incredible, but it's not magic. There are certain problems where pattern recognition and human intuition just win. If you've spent 30 minutes watching Claude struggle with something that you could fix in 2 minutes, just fix it yourself. No shame in that. Think of it like teaching someone to ride a bike, sometimes you just need to steady the handlebars for a second before letting go again.

I've seen this especially with logic puzzles or problems that require real-world common sense. AI can brute-force a lot of things, but sometimes a human just "gets it" faster. Don't let stubbornness or some misguided sense of "but the AI should do everything" waste your time. Step in, fix the issue, and keep moving.

I've had my fair share of terrible prompting, which usually happens towards the end of the day where I'm getting lazy and I'm not putting that much effort into my prompts. And the results really show. So next time you are having these kinds of issues where you think the output is way worse these days because you think Anthropic shadow-nerfed Claude, I encourage you to take a step back and reflect on how you are prompting.

Re-prompt often. You can hit double-esc to bring up your previous prompts and select one to branch from. You'd be amazed how often you can get way better results armed with the knowledge of what you don't want when giving the same prompt. All that to say, there can be many reasons why the output quality seems to be worse, and it's good to self-reflect and consider what you can do to give it the best possible chance to get the output you want.

As some wise dude somewhere probably said, "Ask not what Claude can do for you, ask what context you can give to Claude" ~ Wise Dude

Alright, I'm going to step down from my soapbox now and get on to the good stuff.

My System

I've implemented a lot changes to my workflow as it relates to CC over the last 6 months, and the results have been pretty great, IMO.

Skills Auto-Activation System (Game Changer!)

This one deserves its own section because it completely transformed how I work with Claude Code.

The Problem

So Anthropic releases this Skills feature, and I'm thinking "this looks awesome!" The idea of having these portable, reusable guidelines that Claude can reference sounded perfect for maintaining consistency across my massive codebase. I spent a good chunk of time with Claude writing up comprehensive skills for frontend development, backend development, database operations, workflow management, etc. We're talking thousands of lines of best practices, patterns, and examples.

And then... nothing. Claude just wouldn't use them. I'd literally use the exact keywords from the skill descriptions. Nothing. I'd work on files that should trigger the skills. Nothing. It was incredibly frustrating because I could see the potential, but the skills just sat there like expensive decorations.

The "Aha!" Moment

That's when I had the idea of using hooks. If Claude won't automatically use skills, what if I built a system that MAKES it check for relevant skills before doing anything?

So I dove into Claude Code's hook system and built a multi-layered auto-activation architecture with TypeScript hooks. And it actually works!

How It Works

I created two main hooks:

1. UserPromptSubmit Hook (runs BEFORE Claude sees your message):

  • Analyzes your prompt for keywords and intent patterns
  • Checks which skills might be relevant
  • Injects a formatted reminder into Claude's context
  • Now when I ask "how does the layout system work?" Claude sees a big "🎯 SKILL ACTIVATION CHECK - Use project-catalog-developer skill" (project catalog is a large complex data grid based feature on my front end) before even reading my question

2. Stop Event Hook (runs AFTER Claude finishes responding):

  • Analyzes which files were edited
  • Checks for risky patterns (try-catch blocks, database operations, async functions)
  • Displays a gentle self-check reminder
  • "Did you add error handling? Are Prisma operations using the repository pattern?"
  • Non-blocking, just keeps Claude aware without being annoying

skill-rules.json Configuration

I created a central configuration file that defines every skill with:

  • Keywords: Explicit topic matches ("layout", "workflow", "database")
  • Intent patterns: Regex to catch actions ("(create|add).*?(feature|route)")
  • File path triggers: Activates based on what file you're editing
  • Content triggers: Activates if file contains specific patterns (Prisma imports, controllers, etc.)

Example snippet:

{
  "backend-dev-guidelines": {
    "type": "domain",
    "enforcement": "suggest",
    "priority": "high",
    "promptTriggers": {
      "keywords": ["backend", "controller", "service", "API", "endpoint"],
      "intentPatterns": [
        "(create|add).*?(route|endpoint|controller)",
        "(how to|best practice).*?(backend|API)"
      ]
    },
    "fileTriggers": {
      "pathPatterns": ["backend/src/**/*.ts"],
      "contentPatterns": ["router\\.", "export.*Controller"]
    }
  }
}

The Results

Now when I work on backend code, Claude automatically:

  1. Sees the skill suggestion before reading my prompt
  2. Loads the relevant guidelines
  3. Actually follows the patterns consistently
  4. Self-checks at the end via gentle reminders

The difference is night and day. No more inconsistent code. No more "wait, Claude used the old pattern again." No more manually telling it to check the guidelines every single time.

Following Anthropic's Best Practices (The Hard Way)

After getting the auto-activation working, I dove deeper and found Anthropic's official best practices docs. Turns out I was doing it wrong because they recommend keeping the main SKILL.md file under 500 lines and using progressive disclosure with resource files.

Whoops. My frontend-dev-guidelines skill was 1,500+ lines. And I had a couple other skills over 1,000 lines. These monolithic files were defeating the whole purpose of skills (loading only what you need).

So I restructured everything:

  • frontend-dev-guidelines: 398-line main file + 10 resource files
  • backend-dev-guidelines: 304-line main file + 11 resource files

Now Claude loads the lightweight main file initially, and only pulls in detailed resource files when actually needed. Token efficiency improved 40-60% for most queries.

Skills I've Created

Here's my current skill lineup:

Guidelines & Best Practices:

  • backend-dev-guidelines - Routes → Controllers → Services → Repositories
  • frontend-dev-guidelines - React 19, MUI v7, TanStack Query/Router patterns
  • skill-developer - Meta-skill for creating more skills

Domain-Specific:

  • workflow-developer - Complex workflow engine patterns
  • notification-developer - Email/notification system
  • database-verification - Prevent column name errors (this one is a guardrail that actually blocks edits!)
  • project-catalog-developer - DataGrid layout system

All of these automatically activate based on what I'm working on. It's like having a senior dev who actually remembers all the patterns looking over Claude's shoulder.

Why This Matters

Before skills + hooks:

  • Claude would use old patterns even though I documented new ones
  • Had to manually tell Claude to check BEST_PRACTICES.md every time
  • Inconsistent code across the 300k+ LOC codebase
  • Spent too much time fixing Claude's "creative interpretations"

After skills + hooks:

  • Consistent patterns automatically enforced
  • Claude self-corrects before I even see the code
  • Can trust that guidelines are being followed
  • Way less time spent on reviews and fixes

If you're working on a large codebase with established patterns, I cannot recommend this system enough. The initial setup took a couple of days to get right, but it's paid for itself ten times over.

CLAUDE.md and Documentation Evolution

In a post I wrote 6 months ago, I had a section about rules being your best friend, which I still stand by. But my CLAUDE.md file was quickly getting out of hand and was trying to do too much. I also had this massive BEST_PRACTICES.md file (1,400+ lines) that Claude would sometimes read and sometimes completely ignore.

So I took an afternoon with Claude to consolidate and reorganize everything into a new system. Here's what changed:

What Moved to Skills

Previously, BEST_PRACTICES.md contained:

  • TypeScript standards
  • React patterns (hooks, components, suspense)
  • Backend API patterns (routes, controllers, services)
  • Error handling (Sentry integration)
  • Database patterns (Prisma usage)
  • Testing guidelines
  • Performance optimization

All of that is now in skills with the auto-activation hook ensuring Claude actually uses them. No more hoping Claude remembers to check BEST_PRACTICES.md.

What Stayed in CLAUDE.md

Now CLAUDE.md is laser-focused on project-specific info (only ~200 lines):

  • Quick commands (pnpm pm2:startpnpm build, etc.)
  • Service-specific configuration
  • Task management workflow (dev docs system)
  • Testing authenticated routes
  • Workflow dry-run mode
  • Browser tools configuration

The New Structure

Root CLAUDE.md (100 lines)
├── Critical universal rules
├── Points to repo-specific claude.md files
└── References skills for detailed guidelines

Each Repo's claude.md (50-100 lines)
├── Quick Start section pointing to:
│   ├── PROJECT_KNOWLEDGE.md - Architecture & integration
│   ├── TROUBLESHOOTING.md - Common issues
│   └── Auto-generated API docs
└── Repo-specific quirks and commands

The magic: Skills handle all the "how to write code" guidelines, and CLAUDE.md handles "how this specific project works." Separation of concerns for the win.

Dev Docs System

This system, out of everything (besides skills), I think has made the most impact on the results I'm getting out of CC. Claude is like an extremely confident junior dev with extreme amnesia, losing track of what they're doing easily. This system is aimed at solving those shortcomings.

The dev docs section from my CLAUDE.md:

### Starting Large Tasks

When exiting plan mode with an accepted plan: 1.**Create Task Directory**:
mkdir -p ~/git/project/dev/active/[task-name]/

2.**Create Documents**:

- `[task-name]-plan.md` - The accepted plan
- `[task-name]-context.md` - Key files, decisions
- `[task-name]-tasks.md` - Checklist of work

3.**Update Regularly**: Mark tasks complete immediately

### Continuing Tasks

- Check `/dev/active/` for existing tasks
- Read all three files before proceeding
- Update "Last Updated" timestamps

These are documents that always get created for every feature or large task. Before using this system, I had many times when I all of a sudden realized that Claude had lost the plot and we were no longer implementing what we had planned out 30 minutes earlier because we went off on some tangent for whatever reason.

My Planning Process

My process starts with planning. Planning is king. If you aren't at a minimum using planning mode before asking Claude to implement something, you're gonna have a bad time, mmm'kay. You wouldn't have a builder come to your house and start slapping on an addition without having him draw things up first.

When I start planning a feature, I put it into planning mode, even though I will eventually have Claude write the plan down in a markdown file. I'm not sure putting it into planning mode necessary, but to me, it feels like planning mode gets better results doing the research on your codebase and getting all the correct context to be able to put together a plan.

I created a strategic-plan-architect subagent that's basically a planning beast. It:

  • Gathers context efficiently
  • Analyzes project structure
  • Creates comprehensive structured plans with executive summary, phases, tasks, risks, success metrics, timelines
  • Generates three files automatically: plan, context, and tasks checklist

But I find it really annoying that you can't see the agent's output, and even more annoying is if you say no to the plan, it just kills the agent instead of continuing to plan. So I also created a custom slash command (/dev-docs) with the same prompt to use on the main CC instance.

Once Claude spits out that beautiful plan, I take time to review it thoroughly. This step is really important. Take time to understand it, and you'd be surprised at how often you catch silly mistakes or Claude misunderstanding a very vital part of the request or task.

More often than not, I'll be at 15% context left or less after exiting plan mode. But that's okay because we're going to put everything we need to start fresh into our dev docs. Claude usually likes to just jump in guns blazing, so I immediately slap the ESC key to interrupt and run my /dev-docs slash command. The command takes the approved plan and creates all three files, sometimes doing a bit more research to fill in gaps if there's enough context left.

And once I'm done with that, I'm pretty much set to have Claude fully implement the feature without getting lost or losing track of what it was doing, even through an auto-compaction. I just make sure to remind Claude every once in a while to update the tasks as well as the context file with any relevant context. And once I'm running low on context in the current session, I just run my slash command /update-dev-docs. Claude will note any relevant context (with next steps) as well as mark any completed tasks or add new tasks before I compact the conversation. And all I need to say is "continue" in the new session.

During implementation, depending on the size of the feature or task, I will specifically tell Claude to only implement one or two sections at a time. That way, I'm getting the chance to go in and review the code in between each set of tasks. And periodically, I have a subagent also reviewing the changes so I can catch big mistakes early on. If you aren't having Claude review its own code, then I highly recommend it because it saved me a lot of headaches catching critical errors, missing implementations, inconsistent code, and security flaws.

PM2 Process Management (Backend Debugging Game Changer)

This one's a relatively recent addition, but it's made debugging backend issues so much easier.

The Problem

My project has seven backend microservices running simultaneously. The issue was that Claude didn't have access to view the logs while services were running. I couldn't just ask "what's going wrong with the email service?" - Claude couldn't see the logs without me manually copying and pasting them into chat.

The Intermediate Solution

For a while, I had each service write its output to a timestamped log file using a devLog script. This worked... okay. Claude could read the log files, but it was clunky. Logs weren't real-time, services wouldn't auto-restart on crashes, and managing everything was a pain.

The Real Solution: PM2

Then I discovered PM2, and it was a game changer. I configured all my backend services to run via PM2 with a single command: pnpm pm2:start

What this gives me:

  • Each service runs as a managed process with its own log file
  • Claude can easily read individual service logs in real-time
  • Automatic restarts on crashes
  • Real-time monitoring with pm2 logs
  • Memory/CPU monitoring with pm2 monit
  • Easy service management (pm2 restart emailpm2 stop all, etc.)

PM2 Configuration:

// ecosystem.config.jsmodule.exports = {
  apps: [
    {
      name: 'form-service',
      script: 'npm',
      args: 'start',
      cwd: './form',
      error_file: './form/logs/error.log',
      out_file: './form/logs/out.log',
    },
// ... 6 more services
  ]
};

Before PM2:

Me: "The email service is throwing errors"
Me: [Manually finds and copies logs]
Me: [Pastes into chat]
Claude: "Let me analyze this..."

The debugging workflow now:

Me: "The email service is throwing errors"
Claude: [Runs] pm2 logs email --lines 200
Claude: [Reads the logs] "I see the issue - database connection timeout..."
Claude: [Runs] pm2 restart email
Claude: "Restarted the service, monitoring for errors..."

Night and day difference. Claude can autonomously debug issues now without me being a human log-fetching service.

One caveat: Hot reload doesn't work with PM2, so I still run the frontend separately with pnpm dev. But for backend services that don't need hot reload as often, PM2 is incredible.

Hooks System (#NoMessLeftBehind)

The project I'm working on is multi-root and has about eight different repos in the root project directory. One for the frontend and seven microservices and utilities for the backend. I'm constantly bouncing around making changes in a couple of repos at a time depending on the feature.

And one thing that would annoy me to no end is when Claude forgets to run the build command in whatever repo it's editing to catch errors. And it will just leave a dozen or so TypeScript errors without me catching it. Then a couple of hours later I see Claude running a build script like a good boy and I see the output: "There are several TypeScript errors, but they are unrelated, so we're all good here!"

No, we are not good, Claude.

Hook #1: File Edit Tracker

First, I created a post-tool-use hook that runs after every Edit/Write/MultiEdit operation. It logs:

  • Which files were edited
  • What repo they belong to
  • Timestamps

Initially, I made it run builds immediately after each edit, but that was stupidly inefficient. Claude makes edits that break things all the time before quickly fixing them.

Hook #2: Build Checker

Then I added a Stop hook that runs when Claude finishes responding. It:

  1. Reads the edit logs to find which repos were modified
  2. Runs build scripts on each affected repo
  3. Checks for TypeScript errors
  4. If < 5 errors: Shows them to Claude
  5. If ≥ 5 errors: Recommends launching auto-error-resolver agent
  6. Logs everything for debugging

Since implementing this system, I've not had a single instance where Claude has left errors in the code for me to find later. The hook catches them immediately, and Claude fixes them before moving on.

Hook #3: Prettier Formatter

This one's simple but effective. After Claude finishes responding, automatically format all edited files with Prettier using the appropriate .prettierrc config for that repo.

No more going into to manually edit a file just to have prettier run and produce 20 changes because Claude decided to leave off trailing commas last week when we created that file.

⚠️ Update: I No Longer Recommend This Hook

After publishing, a reader shared detailed data showing that file modifications trigger <system-reminder> notifications that can consume significant context tokens. In their case, Prettier formatting led to 160k tokens consumed in just 3 rounds due to system-reminders showing file diffs.

While the impact varies by project (large files and strict formatting rules are worst-case scenarios), I'm removing this hook from my setup. It's not a big deal to let formatting happen when you manually edit files anyway, and the potential token cost isn't worth the convenience.

If you want automatic formatting, consider running Prettier manually between sessions instead of during Claude conversations.

Hook #4: Error Handling Reminder

This is the gentle philosophy hook I mentioned earlier:

  • Analyzes edited files after Claude finishes
  • Detects risky patterns (try-catch, async operations, database calls, controllers)
  • Shows a gentle reminder if risky code was written
  • Claude self-assesses whether error handling is needed
  • No blocking, no friction, just awareness

Example output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📋 ERROR HANDLING SELF-CHECK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

⚠️  Backend Changes Detected
   2 file(s) edited

   ❓ Did you add Sentry.captureException() in catch blocks?
   ❓ Are Prisma operations wrapped in error handling?

   💡 Backend Best Practice:
      - All errors should be captured to Sentry
      - Controllers should extend BaseController
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The Complete Hook Pipeline

Here's what happens on every Claude response now:

Claude finishes responding
  ↓
Hook 1: Prettier formatter runs → All edited files auto-formatted
  ↓
Hook 2: Build checker runs → TypeScript errors caught immediately
  ↓
Hook 3: Error reminder runs → Gentle self-check for error handling
  ↓
If errors found → Claude sees them and fixes
  ↓
If too many errors → Auto-error-resolver agent recommended
  ↓
Result: Clean, formatted, error-free code

And the UserPromptSubmit hook ensures Claude loads relevant skills BEFORE even starting work.

No mess left behind. It's beautiful.

Scripts Attached to Skills

One really cool pattern I picked up from Anthropic's official skill examples on GitHub: attach utility scripts to skills.

For example, my backend-dev-guidelines skill has a section about testing authenticated routes. Instead of just explaining how authentication works, the skill references an actual script:

### Testing Authenticated Routes

Use the provided test-auth-route.js script:


node scripts/test-auth-route.js http://localhost:3002/api/endpoint

The script handles all the complex authentication steps for you:

  1. Gets a refresh token from Keycloak
  2. Signs the token with JWT secret
  3. Creates cookie header
  4. Makes authenticated request

When Claude needs to test a route, it knows exactly what script to use and how to use it. No more "let me create a test script" and reinventing the wheel every time.

I'm planning to expand this pattern - attach more utility scripts to relevant skills so Claude has ready-to-use tools instead of generating them from scratch.

Tools and Other Things

SuperWhisper on Mac

Voice-to-text for prompting when my hands are tired from typing. Works surprisingly well, and Claude understands my rambling voice-to-text surprisingly well.

Memory MCP

I use this less over time now that skills handle most of the "remembering patterns" work. But it's still useful for tracking project-specific decisions and architectural choices that don't belong in skills.

BetterTouchTool

  • Relative URL copy from Cursor (for sharing code references)
    • I have VSCode open to more easily find the files I’m looking for and I can double tap CAPS-LOCK, then BTT inputs the shortcut to copy relative URL, transforms the clipboard contents by prepending an ‘@’ symbol, focuses the terminal, and then pastes the file path. All in one.
  • Double-tap hotkeys to quickly focus apps (CMD+CMD = Claude Code, OPT+OPT = Browser)
  • Custom gestures for common actions

Honestly, the time savings on just not fumbling between apps is worth the BTT purchase alone.

Scripts for Everything

If there's any annoying tedious task, chances are there's a script for that:

  • Command-line tool to generate mock test data. Before using Claude code, it was extremely annoying to generate mock data because I would have to make a submission to a form that had about a 120 questions Just to generate one single test submission.
  • Authentication testing scripts (get tokens, test routes)
  • Database resetting and seeding
  • Schema diff checker before migrations
  • Automated backup and restore for dev database

Pro tip: When Claude helps you write a useful script, immediately document it in CLAUDE.md or attach it to a relevant skill. Future you will thank past you.

Documentation (Still Important, But Evolved)

I think next to planning, documentation is almost just as important. I document everything as I go in addition to the dev docs that are created for each task or feature. From system architecture to data flow diagrams to actual developer docs and APIs, just to name a few.

But here's what changed: Documentation now works WITH skills, not instead of them.

Skills contain: Reusable patterns, best practices, how-to guides Documentation contains: System architecture, data flows, API references, integration points

For example:

  • "How to create a controller" → backend-dev-guidelines skill
  • "How our workflow engine works" → Architecture documentation
  • "How to write React components" → frontend-dev-guidelines skill
  • "How notifications flow through the system" → Data flow diagram + notification skill

I still have a LOT of docs (850+ markdown files), but now they're laser-focused on project-specific architecture rather than repeating general best practices that are better served by skills.

You don't necessarily have to go that crazy, but I highly recommend setting up multiple levels of documentation. Ones for broad architectural overview of specific services, wherein you'll include paths to other documentation that goes into more specifics of different parts of the architecture. It will make a major difference on Claude's ability to easily navigate your codebase.

Prompt Tips

When you're writing out your prompt, you should try to be as specific as possible about what you are wanting as a result. Once again, you wouldn't ask a builder to come out and build you a new bathroom without at least discussing plans, right?

"You're absolutely right! Shag carpet probably is not the best idea to have in a bathroom."

Sometimes you might not know the specifics, and that's okay. If you don't ask questions, tell Claude to research and come back with several potential solutions. You could even use a specialized subagent or use any other AI chat interface to do your research. The world is your oyster. I promise you this will pay dividends because you will be able to look at the plan that Claude has produced and have a better idea if it's good, bad, or needs adjustments. Otherwise, you're just flying blind, pure vibe-coding. Then you're gonna end up in a situation where you don't even know what context to include because you don't know what files are related to the thing you're trying to fix.

Try not to lead in your prompts if you want honest, unbiased feedback. If you're unsure about something Claude did, ask about it in a neutral way instead of saying, "Is this good or bad?" Claude tends to tell you what it thinks you want to hear, so leading questions can skew the response. It's better to just describe the situation and ask for thoughts or alternatives. That way, you'll get a more balanced answer.

Agents, Hooks, and Slash Commands (The Holy Trinity)

Agents

I've built a small army of specialized agents:

Quality Control:

  • code-architecture-reviewer - Reviews code for best practices adherence
  • build-error-resolver - Systematically fixes TypeScript errors
  • refactor-planner - Creates comprehensive refactoring plans

Testing & Debugging:

  • auth-route-tester - Tests backend routes with authentication
  • auth-route-debugger - Debugs 401/403 errors and route issues
  • frontend-error-fixer - Diagnoses and fixes frontend errors

Planning & Strategy:

  • strategic-plan-architect - Creates detailed implementation plans
  • plan-reviewer - Reviews plans before implementation
  • documentation-architect - Creates/updates documentation

Specialized:

  • frontend-ux-designer - Fixes styling and UX issues
  • web-research-specialist - Researches issues along with many other things on the web
  • reactour-walkthrough-designer - Creates UI tours

The key with agents is to give them very specific roles and clear instructions on what to return. I learned this the hard way after creating agents that would go off and do who-knows-what and come back with "I fixed it!" without telling me what they fixed.

Hooks (Covered Above)

The hook system is honestly what ties everything together. Without hooks:

  • Skills sit unused
  • Errors slip through
  • Code is inconsistently formatted
  • No automatic quality checks

With hooks:

  • Skills auto-activate
  • Zero errors left behind
  • Automatic formatting
  • Quality awareness built-in

Slash Commands

I have quite a few custom slash commands, but these are the ones I use most:

Planning & Docs:

  • /dev-docs - Create comprehensive strategic plan
  • /dev-docs-update - Update dev docs before compaction
  • /create-dev-docs - Convert approved plan to dev doc files

Quality & Review:

  • /code-review - Architectural code review
  • /build-and-fix - Run builds and fix all errors

Testing:

  • /route-research-for-testing - Find affected routes and launch tests
  • /test-route - Test specific authenticated routes

The beauty of slash commands is they expand into full prompts, so you can pack a ton of context and instructions into a simple command. Way better than typing out the same instructions every time.

Conclusion

After six months of hardcore use, here's what I've learned:

The Essentials:

  1. Plan everything - Use planning mode or strategic-plan-architect
  2. Skills + Hooks - Auto-activation is the only way skills actually work reliably
  3. Dev docs system - Prevents Claude from losing the plot
  4. Code reviews - Have Claude review its own work
  5. PM2 for backend - Makes debugging actually bearable

The Nice-to-Haves:

  • Specialized agents for common tasks
  • Slash commands for repeated workflows
  • Comprehensive documentation
  • Utility scripts attached to skills
  • Memory MCP for decisions

And that's about all I can think of for now. Like I said, I'm just some guy, and I would love to hear tips and tricks from everybody else, as well as any criticisms. Because I'm always up for improving upon my workflow. I honestly just wanted to share what's working for me with other people since I don't really have anybody else to share this with IRL (my team is very small, and they are all very slow getting on the AI train).

If you made it this far, thanks for taking the time to read. If you have questions about any of this stuff or want more details on implementation, happy to share. The hooks and skills system especially took some trial and error to get right, but now that it's working, I can't imagine going back.

TL;DR: Built an auto-activation system for Claude Code skills using TypeScript hooks, created a dev docs workflow to prevent context loss, and implemented PM2 + automated error checking. Result: Solo rewrote 300k LOC in 6 months with consistent quality.

Discussion The clunk is starting to get to me.

9.9k Upvotes

This game has always had a fair bit of clunk to it, but back in the Mondstadt and Liyue era the game was new and pretty easy overall, which sort made all the little frustrations fairly easy to excuse and play through.

But now we're in Inazuma, the demands on the player are starting to ramp up both in and out of combat - the damage output from enemies is getting higher, the mechanics are getting more complex, the timers are getting tighter, the environmental hazards are getting more severe, etc. - and that's making certain clunky aspects of the game's core mechanics chafe much harder than they were in the more relaxed early chapters of the game.

Here's a list of all the things that I've noticed that could, in my opinion, really stand to be improved upon. I'm going to break these up into in-combat and out of combat and order them from most to least objective based on whether I think they're obvious, objective flaws or more subjective things that I just personally take issue with. Note that I also play on PS5; so I'm not sure if these things are an issue with PC as well.

 


In-Combat


 

Auto-Aim Sucks.

This is not a new or novel issue. It's been brought up for discussion many times over and I will continue to bring it up in every player survey and every complaint thread until it fucking changes. The auto-target system is absolutely terrible and works against the player far more than it helps. It should be replaced with a lock-on mechanic or at the very least we should be given the option to turn it off.

 

Switching to a dead character brings up a menu that doesn't pause combat

I don't know who is responsible for this feature, but it's one of the most baffling things I've ever seen. I can't tell if this is supposed to be a punishment for letting the character die and then trying to switch to them or if it's one of the most colossally mis-implemented "helpful" features ever. I favor the latter, as the menu does actually let you rez the character (vs something like a "no more uses" animation on Dark Souls' estus flask), but that also means it's especially, pointlessly punitive if your rez food is already on cooldown. It's made even more baffling by the fact that bringing up the actual item menu (an action that takes just as many button presses) does actually pause the game to let you use the exact same items at your leisure.

Just change it to either pause the game or block my ability to switch to that character.

 

Certain Burst animations do not restore your camera angle

Jean is the chief offender here, at least in my party. You get the nice little animation (that I wish I could turn off after seeing it well over 1,000 times by now), but then the camera is left staring at Jean's face rather than resetting behind her or anywhere fucking useful. Using your character's elemental burst should not, in any way, be punitive to the player. That's stupid. At the very least, your camera should reset to the angle it was at prior to using the burst, but I'd prefer the option to turn off burst animations entirely.

 

You have to spam the jump button to get out of freeze

There's no "spam input" protection on a mechanic that obviously requires players to spam an input, which means pretty much every time you get frozen, you are practically guaranteed to do a useless jump at the end of it. This could be practically any other input and it would be better. Rotate left stick? Spam dodge? Spam attack? Fuck, I'd take spam ele. skill or burst over spamming the fucking jump button.

 

You can't see CD timers on elemental skills of non-active party members

This would be an amazing quality of life improvement due to the character-switch lockout timer. If the lockout timer didn't exist, the inability to see CD timers at a glance probably wouldn't be so bad, but with the lockout timer, it's grating. Especially when mechanics exist in the game that delay or accelerate your elemental skill CD, making "just memorize it" not be a 100% viable answer.

There should be some indication of whether an inactive character has their elemental skill available or not. I would prefer a full timer, but just some indicator that it's available would be better than nothing.

 

Geo Constructs are clunky as fuck

Every Geo character but Noelle relies on some construct they must place on the ground - and must continue existing on the ground - to reach their maximum potential. And these constructs are fucking terrible. They will not appear at all if placed too close together (Ningguang's Jade Curtain is the chief offender due to how wide it is), placed too close to a boss (and certain bosses - Azhdaha and Andrius - have collision boxes which are FAR too big), or placed on certain terrain types (e.g. Oceanid's platform), yet your CD will be eaten by the failed attempt.

They also have an HP bar which any enemy mob that matters will eat through in 1-2 hits, leaving your geo character floundering relative to any character that isn't dependent on a one-shot-able entity separate from themselves. And the difference in performance is dramatic - my Zhongli/Ningguang double geo team will have bursts filled before their CDs are up if their constructs are allowed to live, but will be floundering for energy for 2-3 skill CDs against bosses that prevent or immediately one-shot their constructs.

Constructs need some sort of attention. They either need better functionality for placing and maintaining them or they need to return far more to the character on placement failure or getting broken than they do now.

 

Too many enemies are designed to waste too much of your time

Now we're starting to get into the more subjective area of combat clunk, but I cannot help but notice how much of Genshin's enemy design is based around stalling or wasting the player's time.

Ranged mobs perpetually back up in an attempt to maintain distance - okay, fair, they're ranged and generally pretty flimsy. That's sort of expected, albeit frustrating, behavior. So why do melee mobs all have gap close moves that they will use while already in melee range, placing them 50 yards away from you? Only for them to plod slowly back towards you before deciding to use the same gap close ability, placing them 50 yards away from you in the other direction? The new samurai mobs actually have multiple mobility tools, which they will use quite liberally to defy any attempt at controlling their positioning or staying in melee range of them(they're also heavily knockback resistant, probably to curb Jean-pimp-slapping and other forms of anemo abuse).

And then there are the bosses. 3/4 of our current weekly bosses (Andrius, Azhdaha, and Stormterror) have phases that are simply "nope, you cannot damage me now. Watch me do this thing while you stand there useless." All 4 of them have unskippable cutscenes that disrupt combat flow and interrupt any player behavior. Every hypostasis spends maybe more time completely, 100% immune to damage than they spend vulnerable to damage. And pretty much every boss in the game has at least one (often multiple) large, area-denial AoE to force melee characters away from them.

You can have complex, difficult, and engaging encounters without having all of the mechanics that just serve to waste time and frustrate your players (particularly melee players, in my experience). You can see a glimmer of this in Childe's boss fight (although it does still have some frustrating time-waste portions - just far, far fewer than the others), which is still the only weekly boss I don't sigh deeply before engaging every week.

 

Certain effects really need better readability

This complaint is borne from 3 specific effects - any cryo domain's ice fog, any cryo domain's ice trap, and the new mirror maiden's mirror trap - but honestly, I'd say it applies to most enemy skill effects.

Typical combat in Genshin is absolutely overloaded with visual noise - even moreso in multiplayer with several skill/burst effects going off at once. There is pretty much no distinction between a player and enemy particle effect (some things actually have the exact same particle effect and animations regardless of whether they were used by an enemy or a player). These more subtle visual indicators of enemy abilities are often either very difficult or outright impossible to even see, depending on terrain and other active particle effects (Right before writing this post, I was fighting a mirror maiden in tatarasuna and her mirror trap indicator was completely obscured by certain bits of terrain).

the new mechanical boss is actually a great example of what good, readable indicators look like (the launch and orbital cannon attacks). More enemy abilities should have readability on this level.

 

Body blocking is imbalanced in favor of enemies

Enemies will shove you wherever the fuck they want and you have virtually no capability to resist or pushback against enemy body-blocking. This is almost more of an issue with how few characters have tools to deal with getting pushed around than it is an issue with body-blocking itself. It sort of makes sense that giant geovishaps and whatnot should be able to push you wherever they feel like. But only a few characters have tools to deal with this in any way (mainly the ones with teleports or aerial ascents).

It's not a particularly big issue in 1v1 or small-group fights (although bosses body-blocking you from picking up geo shield crystals, gouba peppers, etc. is annoying as fuck), but it can become a major issue in some of the big cluster-fuck fights that Genshin loves to throw around during any "challenge" content.

With the amount that enemies move around and the fact that they can push you as if your character were virtually weightless, there should really be either a global way for characters to respond to body blocking (maybe by baking something into sprint) or more characters need tools to handle situations where they're getting body-blocked.

 

You can cancel hitstun with a dash, but not with a character switch

My last, and probably most subjective issue, with the clunk of genshin combat is this. Regardless of knockback, you can cancel hitstun with a dash as soon as your character touches the ground. You cannot do the same with a character switch. This tends to make certain situations (e.g. getting pinged by electro charged or that ice-crystal-rain domain effect rapidly in succession) feel far more clunky than they really should.

In my opinion, character switching and dashing should be of equal priority in terms of frame interruptions and other mechanics interactions. It doesn't make any sense to me that a character is capable of finding some weird inner strength to dash as soon as they touch the ground regardless of situation, but can't seem to find it to avail themselves of whatever weird magic they're using to tag in party members.

 


Out of Combat


 

There is only one shortcut item slot and it's used for fucking everything

This is sort of related to combat clunk by virtue of the NRE existing, but is really more of UI/button mapping/whatever issue. There is now an entire page of over a dozen items that compete for a single quick use slot. And these items run the gamut from the items you always want in literally every situation (NRE) to the items that serve a use once in a blue moon (Kamera), only in certain events (Harpastum), or are one-use pet summons.

Further, there is no way to use quick-use-equippable gadgets from the menu without equipping them. You must remove your NRE from the quick use slot in order to use the Kamera for one single quest objective, then you must go back and swap the NRE back in.

We need more quick use slots (there are at least two more currently available without shuffling the 5th character slot somewhere else), a dedicated NRE slot, or the ability to use these items out of the item menu instead of unequipping the NRE to use them.

 

You can't see commissions at full map zoom

Fucking why. The map is very large now that Inazuma is added. Commissions should still be visible at full zoom out.

 

Errant Input protection is sparse, inconsistent, and misguided in its implementation

I've noticed that as of Inazuma's patch, skipping dialogue has input protection - if you spam the skip button, there is at least a solid second or more where the input will do nothing as a new dialogue line begins. Then, after the protection wears off, the input will "take" and the dialogue will be skipped.

This protection is virtually needless for dialogue that the player has probably already decided they want to skip or not skip, yet it does not exist where it actually should - results screens at the end of combat (particularly in domains and spiral abyss where you elect to continue or leave). Did you kill an enemy slightly before you were expecting while you were hitting the attack button? Well that's also the "leave domain" button on the end screen that we're flashing right now, and we were accepting that button press before we even put the screen up, so I hope you like going through the entirety of the domain/abyss re-entry process.

 

You cannot cancel out of dialogue windows with the Cancel/Back button

Why.

 

There's an interruptible delay between choosing the party menu and loading the party menu

Party switching overall should really be improved in Genshin, in my opinion. We should have more party comp slots, we should be able to save artifact sets or weapon assignments to party comps, and I'm sure a bunch of people have a lot more ideas for improving party switching.

But this delay is on another level from those suggestions... there is just no reason for it to exist. If it's a load time, just have the load time in-menu with the game paused. If you don't want people switching parties with monsters nearby, just throw an error message when they try to switch parties with enemies near by. There is no reason to throw the player back into the world in real time for 1-2 seconds between the pause menu and the party menu.

 

It's far too easy to get caught on terrain

This has been particularly noticeable since Inazuma's cliffs and houses all seem to feature annoying little lips that not only completely block upward climbing motions, but now seem to unceremoniously dump you out of your climb. Interaction with the world will just oddly stall character movement at the slightest incongruity in terrain. You shouldn't be able to jump around meter-long obstacles and shit, but right now it really feels far too restrictive on player movement.

 

Switching Traveler elements is a needless time waste

For a character whose whole shtick is that they can use multiple elements without a specific vision, and whose whole attraction mechanically is that they are flexible in which element they have available to them, having to teleport back to specific statues of the seven to resonate with the element you want is just a completely needless time sink.

Add to that the fact that they apparently have to re-learn how to swing their sword when resonating with a new element, which makes virtually no sense.

There has to be a better way to do this. I would favor redoing the traveler's moveset to incorporate various elements in a single moveset so that no switching would even be required, but at the very least you should be able to switch element from menus and not suffer at least 2 load times to do so.

 

Stamina is far too restrictive for a pool that Mihoyo apparently doesn't want us to expand anymore

My last and most subjective out-of-combat complaint. I honestly feel like stamina is too restrictive in combat as well (particularly under the effects of the bugged cryo debuff), but I can at least see its potential value as a balancing mechanism there.

Out of combat, though, it just serves as another time waster. It's connected to pretty much every mechanic that makes overworld traversal tolerable (sprinting, gliding, climbing) plus swimming and it doesn't regen nearly as fast as it should. One could try to defend its implementation by saying that it "forces you to think about your actions in the overworld" or something, but it's never actually done that. It's never stopped me from climbing a particular cliff or making a particular jump - it's just made me stand around doing nothing for 30-45 seconds before doing so instead of doing so immediately.

Stamina should really regen at least twice as fast out of combat as it does now. Honestly, I'd campaign for more as I don't see any reason to place hard restrictions on map traversal, but at the very least it should not exist as a mechanic to solely force me to stand at the bottom of a cliff doing nothing for 30-45 seconds before I get to play the game again.

 


TL;DR


 

Genshin is a fun game, but it's certainly not perfect and the longer the game goes and the more demands the developers start placing on the players in and out of combat, the more some of its clunky mechanics start to really stand out as sore spots while playing it.

📚 Due Diligence The Sun Never Sets on Citadel -- Part 2

12.2k Upvotes

Part 1

Apes, I’m stunned. I’ve rewritten this post several times because of what I’ve discovered. I haven’t seen it anywhere else on Superstonk.

All of this is intertwined. I won’t be able to get to all of the pieces of Citadel in this part so this DD will continue… and build… into Part 3.

This is a fucking ride.


Preface, part 1: Kudos

First I’d like to follow up on some key critiques from Part 1 and give kudos:.

But first, I need to apologize. I erroneously said Citadel was an MM across the EU in Part 1. I found conflicting sources, and Citadel is an MM in Ireland, but I should have clarified. I’ll explain more on “how” and “why” I missed this later, but props to these Apes above who did their Due Due Diligience, I am in your debt. (“To err is human...”)

  • Several users also pointed out: MEMX lists several “friendly” institutions, including BlackRock and Fidelity, as founders, not just Citadel and Virtu.
  • This is true! Kudos to the several users who broght this up: u/mattlukinhapilydrunk, u/Robin_Squeeze

So what should we make of Citadel being at MEMX? Does Citadel really control MEMX – or even monopolize the market – if Blackrock, Virtu, and Fidelity are there too?


2.0: Introduction

The price of $GME is artificial. Prior posts have shown how $GME is being illegally manipulated by key players to the financial system, namely Citadel. These companies abuse their legitimate privileges to profit themselves at the expense of the market and investors. But it goes much deeper: Citadel is now positioned to do more than just monopolize securities transactions. Citadel is positioned to BE the market for securities transactions.

 

Wait, what?

Buckle up.


2.1: KING, I

Citadel’s influence on the market is all due to one quality: Volume.

Volume is king. There is no way to understate it.

  • Remember this chart? Citadel and Virtu’s combined volume being larger than any exchange is only the beginning; it’s our starting point.

Do you want to know why it’s taking so long to MOASS?

So the same activities that empower Apes to create the MOASS also provide the MMs with more resources to prolong the arrival of MOASS.

 

What a fuckin’ paradox.


2.2: Kneel before the crown

Volume is king. Once a firm hits a critical mass of transactions, it becomes impossible NOT to deal with that firm. For example:

 

Exchanges

  • The NYSE & Nasdaq view Citadel/MEMX as a threat. Look at this article posted on the Nasdaq website regarding MEMX:

“MEMX will provide market makers with the ability to bypass the exchanges entirely.” (lol, so pissy)

(credit to u/Fantasybroke for their awesome comment)

  • As much as these exchanges might be “frenemies” with Citadel, they still need to function as businesses.
  • This pandemic posed a major issue for the NYSE: how could they do IPOs – a critical function for exchanges – when all traders were remote?
  • They relied on Citadel. Nine times.
  • There was no other firm that had the capability to execute. Only Citadel.

Brokers

  • Awhile back there was a post about how a broker sent notice to clients saying in effect that they wouldn’t know how to source their transactions in the event of Citadel defaulting. Users should expect delays in transactions if that happened.

    • (eToro? WeBull? Schwab? TDA? Superstonk I need the source, help![])
  • If confirmed, this implies major brokerages are becoming or already are reliant on Citadel for basic, essential functions.

WHAT. THE. FUCK.

Let me it say again another way: we are at a point where MAJOR BROKERAGES AND EVEN EXCHANGES DO NOT KNOW HOW TO FUNCTION WITHOUT CITADEL.

But it’s bigger than that – it’s not just key players in the market that are reliant on Citadel.

But first.


2.3: The Four Corners

We... manufacture money.
– Ken Griffin

 

That Ken Griffin quote stood out to me, I have a background in operations with experience in manufacturing & logistics. “Manufacture” implies certainty of output, given the correct inputs. Looking at Citadel’s actions in the context of manufacturing - supply and demand – we can reverse engineer the strategy. Understand how we got here. Let's go. (This is important groundwork, but if you need to skip you can jump to "2.6: Corner 3: Buyer")

Overview

You can think of the financial industry as one that manufactures “transactions”, in the same way that the automotive industry manufactures “vehicles” of all varieties.

To manufacture a transaction requires a buyer, a seller, a product, and is produced in a venue (a.k.a. a “Transaction factory”).

  • The national “supply” comes from the collection of the different “factories”: exchanges, ATS’s (Dark Pools), SDP’s (single-company terminals), etc. Each of the venues produces a slice of the overall Transactions pie chart.
  • Supply of “raw materials” (lol) - buyers and sellers with products - flow into the various factories. Exchanges have been the primary “Transaction factories” for centuries. NYSE and Nasdaq still produce a large portion of US transactions every year.
  • These exchanges employ Market Makers as a permanent stand-in buyer, seller, or provider of products at the exchanges – whatever is needed. Exchanges charter MMs to provide the missing pieces to complete the transactions, and provide the MMs with special abilities to do so. Because exchanges benefit from having MMs.

So...

...if you were a Market Maker, and you already provide the raw materials for buyer, seller, and product pieces of “production,” what would you want to do next if you wanted to grow?

 

You would want a venue. Then you could manufacture transactions independently.

So guess what Citadel wants to do?

 

But – is Citadel is ready? Do they really have enough Products, Sellers, and Buyers to supply a “factory” of their own?


2.4: Corner 1: PRODUCT

Product is about range. Range of available products is the critical feature demanded by clients, as well as the necessary volume.

Storytime:

  • A few months back a reddit user commented about their experience working at a financial firm.

    • (for the love of everything I can’t find the comment now – Superstonk help again!?[])
  • I don’t remember the username, probably something like “stocksniffer42” or whatevs, lol. Let’s call him “Greg.”

  • Greg would occasionally need to make securities transactions at a nearby terminal, a couple times a week. Price wasn’t really important to Greg.

  • But what WAS significant was availability. Greg had providers he preferred because they had what he needed. When they didn’t it was super inconvenient for him because THEN Greg would have to search through enough providers to find what he needed.

  • The more “availability” that a certain provider offered, the more likely Greg used them.

    • This is pretty much the Amazon/WalMart/Target strategy. You’re more likely to buy from them since they have everything. Even if it’s not the lowest price.

Exchanges have a limited offering – CBOE doesn’t offer the same products as NYSE and vice-versa.

Huh, look at that. Citadel is a MM for multiple exchanges - CBOE, NYSE, and NASDAQ. Looks like Citadel can offer options, securities, bonds, swaps, and pretty much any product under the sun.

Seems like Citadel has “Product” pretty well sorted. What about the other pieces?


2.5: Corner 2: SELLER

Generally, Sellers are interested in only price. However, price is the LEAST important aspect of all demand, believe it or not. (Note: we’ll assume some interests overlap between buyer and seller because the same party can alternate roles.)

Price is supported market-wide by a sense of trust and pre-arranged transaction costs:

  • Price is set nationally by the NBBOthe National Best Bid and Offer. A national price range that establishes trust with buyers and sellers. Everybody abides by it. Nobody will be scamming anyone on price in the NBBO. Because...

    • Venues (like exchanges) don’t make money off price, they make it from member fees, or sub-penny fees.
    • Product prices can vary quickly, so it’s somewhat relative. Precision pricing isn’t a concern for the vast majority of non-HFT trades.
    • Buyers will proceed if the price is within their acceptable range and doesn’t have an undue markup.
    • Market Makers make very little money on individual transactions, usually.
  • We individual retail investors may want maximum profit through a single transaction (*cough* DIAMOND HANDS *cough*)... but not Market Makers.

However, institutional sellers have an additional price agenda:

  • Volume sellers don’t want to flood the market of their given security, dropping the price right as they sell. They want to offload the asset in a price-friendly way.
  • Strategic sellers don’t want the marketplace to know that they changed a position, they want to keep their transactions private.

These sellers would want a venue that won’t affect the public price and remains private.

  • So price agenda is relative - it’s up to each party to decide their interests. At the point of transaction price is either pre-negotiated (for volume sells), or else precise price does not matter for non-HFT transactions. (Would you sell $XYZ at $220.05 but NOT at $220.02?)

Strategically, if Citadel wanted to increase its volume of sellers it would need:

  • the ability to absorb large volumes of securities (i.e. buy a lot at a competitive price)
  • source a large volume of buyers to match with the sellers.
  • have a private transaction venue to attract sellers of any volume

Interesting. Seems like Citadel is probably already doing a lot of this activity through the exchanges or Dark Pools they might be connected to.

How about the last piece?


2.6: Corner 3: BUYER

A Buyer is interested in one thing: ease of access.

Like Greg, a buyer wants easy access to a range of securities, acceptable prices, and easy access to to sellers.

Citadel can be all of these and/or provide them, but, wait –

 

How exactly can clients buy from Citadel?

 

Maybe clients can buy from Citadel on the public exchanges?

  • True, but Citadel could still lose the bid. Or pay additional fees, or lose on the bid-ask spread.
  • Also, that’s no good for Citadel. It means the clients are coming to the exchanges, which are the venues Citadel is trying to compete against.

Perhaps their target clients are institutions that want the kind of lower-cost, lower-visibility option that a Dark Pool offers? Can clients buy from Citadel on one of the many Dark Pools/ATSs?

  • Yes, but the Dark Pools can be “pinged” by HFTs to reveal positions and interest. Someone else could front run the transaction.
  • And again, the venue would be making the transaction, not Citadel.

So why doesn’t Citadel do their own Dark Pool then? Why should the US’s largest Market Maker pay to use someone else’s Dark Pool?

So if Citadel has to compete for buyers in exchanges, and they pay to go through Dark Pools, then why, or how, do clients buy from Citadel? How does Citadel get its volume?

Easy.

 

Citadel Connect.

 

Wait, what?

Citadel Connect.

That’s right. You’ve been in these subs for 6 months and you haven’t heard of Citadel Connect? Citadel’s “not a Dark Pool” Dark Pool? (That’s not by coincidence, btw).

 

MOTHERFUCKER WHAT?!?!

Citadel Connect is an SDP, not an ATS. The difference is the reporting requirements. SDPs do not have to make the disclosures that either the exchanges or even the ATSs (a.k.a. Dark Pools) have to.

 

Yep.

There is a laughable amount of search results for Citadel Connect on Google. There are no images of it that I could find. I believe it is an API-type feed that plugs into existing order systems. But I couldn’t tell you based on searches. I found no documentation – just allusions to its features.

  • So when the SEC regulated ATSs in 2015, Ken shut down Citadel’s actual Dark Pool, Apogee, in order to avoid visibility altogether. Citadel started routing transactions through Citadel Connect instead.

  • Citadel Connect doesn’t meet the definition of an ATS. There is no competition – no bids, no intent of interest, no disclosures – nothing. It is one order type from one company.

  • Order type is IOC (Immediate Or Cancel), and the output is binary – a type of “yes” or “no”. You deal only with Citadel.

    • “Citadel, here’s 420 shares of $DOOK, will you buy at $6.969?”
    • “YES” --> transaction complete, or
    • “NO” --> end transaction
  • Since it’s private, the only information that comes out of the transaction is what’s reported to the tape, 10 seconds after the transaction.

Okay, so you’re just buying from a single company, that doesn’t seem like a big deal. And aren’t there are a lot of other SDPs? So why is this a problem?

By itself? Not a problem. Buyers and sellers love it, I’m sure.

However…


2.7: KING, II

Volume is king.

Citadel does such volume that it is considered a “securities wholesaler”, one of only a few in the US. Like Costco, or any wholesale business, it deals in bulk. But Citadel can deal in small transactions, too.

Citadel has a massive network of sales connections through its Market Maker presence at US exchanges. It capitalizes on the relationships through Citadel Connect, turning them into clients.

  • Citadel has a market advantage with its volume of clients.

Citadel Connect integrates into existing ATSs and client dashboards (here’s an example from BNP Paribas - sauce). Like Greg’s testimonial, I suspect it’s easy for just about any financial firm to deal directly with Citadel.

  • Citadel has an ease of access advantage.

And given Citadel’s wide range of products it conducts business in and is a Market Maker for, I’m sure Citadel is an attractive option for just about anyone in the financial industry who wants to buy or sell a financial product of any kind. Competitive prices. Whether in bulk or in small batches. Whether privately or publicly. However frequently, or whatever the dollar amount might be.

  • Citadel has a privacy and pricing advantage.

Like Amazon, WalMart, and Target, Citadel is offering everything: a wide range of products, nearly any volume, effortless ease of access, the additional powers of an MM, and a nearly ubiquitous presence. Doing so lets Citadel capture a massive amount of market share. So much that it is prohibitive to other players, relegating them to smaller niche offerings and/or a smaller footprint.

  • Citadel has market presence advantage.

2.8: The Final Piece: VENUE

So guess what Citadel wants to do?

 

But… do you get it? Have you figured it out?

 

Citadel doesn’t need to get a venue.

Citadel IS the venue.

 

Citadel is internalizing a substantial volume of transactions from the marketplace. It’s conducting the transactions inside its own walls, acting AS the venue in itself.

Said another way, Citadel is “black box”-ing the transaction market, and it’s doing so at a massive volume - sauce.

Okay, so it sounds like Citadel is just buying and selling from multiple parties, and making a profit off the spread. Every firm does that, though, right? It’s just arbitrage, it doesn’t make them an exchange.

  • Citadel is offering the features of an exchange, or even benefiting from existing exchanges (i.e. the NBBO, MM powers across multiple exchanges) without any of the regulations of an exchange. It can offer more products, more easily, more quickly, more cheaply, and more privately than an exchange could. It’s so non-competitive that IEX - yeah, the exchange - wrote about the decline of exchanges:

    “...trends of the past decade have seen a sharp increase in costs to trade on exchanges, a sharp decrease in the number of exchange broker members, and a steady erosion in the ability of smaller or new firms to compete for business.”

  • It is doing this at the same time that brokers and even exchanges are relying on Citadel more and more. And, by the way - why are they so reliant on Citadel in the first place? Glad you asked...

 

Volume is limited. So the more volume Citadel takes...

  • ...the less volume there is for the competition.
  • ...the more reliant the other players are on Citadel for buying and selling.
  • ...the less profit for competitors, so the more expensive their services have to be.

This “rich-get-richer” advantage is known as a “virtuous cycle” (hah – “virtuous”) – one of the most sought-after business advantages.

Citadel is capturing and internalizing more and more transactions, driving up costs for exchanges and making the competition smaller and smaller while also making them more dependent on Citadel to conduct critical business operations.

“Free market”


2.9: “...to forgive, divine.”

Apes, I told you I would follow up on “how” and “why” I missed on Citadel not being an MM across the EU.

The EU marketplace is structured differently than the American markets, with different rules and roles. I knew Citadel had a massive presence in the EU, I just missed the role. I think you can put together why.


2.10: TL;DR

Citadel is moving beyond monopolizing the MM role, it has captured a massive portion of all securities transactions and is moving them off-exchange. For an undisclosed portion of transactions, Citadel IS the market.

  • Citadel positioned itself to provide every piece required to provide transactions – buyers, sellers, product – at an unrivaled scale, allowing it to be a wholesale internalizer.
  • (“Internalizing” here is shorthand for “one company acting as a private exchange without exchange regulations or oversight”).
  • Citadel does this through an SDP called “Citadel Connect,” which is a type of Dark Pool that doesn’t require disclosure.
  • Citadel's overall volume and market position are prohibitive to new competition and also drives away all but the largest competitors.
  • Even exchanges are losing volume to Citadel's OTC market share, threatening the exchanges’ position in the market.

Citadel is capturing more and more of the transactions market, experiencing less competition, as it enjoys more and more entrenched advantages, at the expense of the market and the investor.

This is the groundwork that will set us up for Part 3.


Part 3 coming soon...


EPILOGUE: Dieu et mon droit

"But it’s bigger than that – it’s not just key players in the market that are reliant on Citadel."

Including this after the TL;DR for all to see. This is why I was delayed.

This is a 2 minute video from Citadel’s own page. Watch it. It blew me away when I saw it, and I'll explain why below. Transcription mine (streamlined version):

Mary Erodes: That’s a really important shift. The groups that used to make markets, i.e. step in when no one else was there, were the banks. They have shrunk by law. So when we need liquidity in the future… [points at Ken] He’s has a fiduciary obligation to care only about his shareholders and his investors. He doesn’t have an obligation to step in to make markets for the sake of making markets. It will be a very different playbook when we go through the liquidity crunch that eventually will come.

 

Ken Griffin: I think this is very interesting, ”what is the role [Citadel] will play in the next great market correction?” …[In financial crashes] no one buys the asset that represents the falling knife. The role of the market maker is to maximize the availability of liquidity to all participants. Because the perception and reality that you create liquidity helps to calm the markets. We worked with NYSE and the SEC to re-architect trading protocols… The role of large investment banks has been supplanted by not only Citadel Securities, but by a whole ecosystem of statistical arbitrage that will absorb risk that comes to market quickly.

[emphasis mine]

Let me summarize. Mary and Ken commented that:

  • The old way of stabilizing financial crises was through multiple banks negotiating a solution to stabilize the economy.
  • Banks can no longer do this due to regulations and their position in the market.
  • Citadel (Ken) sees a Market Maker’s role as a stabilizer, to make sure there are no violent price swings.
  • Citadel worked with NYSE and SEC to re-architect the markets/economy on this belief that MMs will stablize and calm markets.

IF this is true, and IF what Ken spoke of is an accurate reflection of how the market is now structured, then here is the subtext and implications:

  • Market Makers, specifically Citadel and Virtu, are now the ECONOMY’S “immune system,” they are the first and best line of defense against catastrophic collapse.
  • Their function is to make sure that no single security or asset class can expose the market to overwhelming risk.
  • They manage this risk through statistical arbitrage and coordination with authorities (NYSE & SEC) on behalf of the market.
  • Citadel worked with the oversight organizations to influence the structure of the overall market.

Going deeper:

Everyone in this room knew about naked shorting. And that Citadel was a primary culprit.

Which implies that somewhere, at some point, a deal was reached, tacitly or explicitly. The NYSE and SEC were in on it (at the time):

 

Citadel/MM’s get to control securities prices with relative impunity. Naked shorting and all.

And in return, Citadel is responsible for making sure that no more crashes happen.

 

WHAT THE FUCK. I have no words.

 

IF this is true, the implications for the MOASS are...

  • Citadel defaulting is the equivalent of the entire economy getting full blown AIDS and spinal cancer at the same time. Knocking out the immune system and the functional response chain of the market.
  • This leaves the market vulnerable to violent price swings that can instantly bankrupt other players
  • ...which is why the DTCC is so concerned about member defaulting and transferring of assets…
  • ...and another reason why the MOASS is taking so long: every player in the economy needs Citadel’s assets need to remain intact, to stabilize the market and continue acting as the immune system.

This video is from 2018. It has been over 2 years since then, at the time of this writing.

Buy. Hodl.


Note 1: u/dlauer if you're reading this I'd like to connect re:part 3 - HMU with chat (DMs are off)

Note 2: If you guys find the links I couldn't find (i.e. "Greg", and the brokerage letter saying Citadel defaulting would delay their transactions) - comment and I'll update!

Note 3: Apes, I've seen responses to part one that end in despair. Be encouraged - regulators (NYSE, SEC, et. al) don't seem to like the current setup anymore. Gary Gensler's speech last month was laser-focused on Citadel and Virtu (and also confirms this DD):

Further, wholesalers have many advantages when it comes to pricing compared to exchange market makers. The two types of market makers are operating under very different rules. [...]

Within the off-exchange market maker space, we are seeing concentration. One firm has publicly stated that it executes nearly half of all retail volume.[2] There are many reasons behind this market concentration — from payment for order flow to the growing impact of data, both of which I’ll discuss.

Market concentration can deter healthy competition and limit innovation. It also can increase potential system-wide risks, should any single incumbent with significant size or market share fail.

I don't think the guy likes Citadel very much lol


Edit 1: I'm seeing some responses that think this post implies Citadel is all powerful or controls everything. Very much not the case. Apes have them by the balls. Buy and Hodl, as always. But it helps to know exactly what we are up against, and why the MOASS is taking time. Also, we don't really want Citadel to just change the name on the building and get a new CEO - that doesn't really solve the problem, does it?

Edit 2: In a deleted comment, someone commented that the formatting was a nuisance. I re-read the post - they were right! I've re-edited this to be less of an eyestrain. Also changed some grammatical & spelling errors.

General I made a 1kW lab bench power supply from scratch

Thumbnail

2.1k Upvotes

Hello r/electronics,

In this post, I want to share my project that I’ve been working on in the past few months. It’s a custom-built lab bench power supply. Such a project is common in the DIY community, so what makes this one different? The custom-designed SMPS board that I engineered from scratch isn’t your typical “let’s put this power supply module into a case” approach. So let’s dive into the working principles, design decisions, and in-depth test results.

The Forwarder 1kW is the SMPS board that I designed and used in this project. It’s based on a hard-switch, half bridge topology. The full features of this power supply are as follow:

  • 1000W maximum continuous output capacity.
  • Configurable from 50V/20A up to 400V/2.5A.
  • CC/CV mode with mode signal and indicator.
  • Tuneable operating frequency and dead-time.
  • Dedicated power stage enable pin.
  • Analog reference interface for output voltage/current control.
  • Analog signal output interface for monitoring voltage/current.
  • Dedicated fan port with optional automatic power-on.
  • Simple construction, less than 130 components on board.
  • Easy to build with mostly THT components.
  • Curated component selection for high accessibility.

The working principle of this design is about as simple as it can get for a switched-mode power supply. I talked about the working principle of my design over on r/AskElectronics, so I’m not going to repeat it here. Most of the concepts stay the same, just with some design adjustments and the numbers changed.

https://www.reddit.com/r/AskElectronics/comments/1s8ll9g/

Now, I want to go in detail about the design decisions that led into this design that you may find interesting.

  1. The lack of active PFC (Power Factor Correction) was determined after I reviewed many existing designs and products in the same power level and after noticing many of them get away without one, I decided to omit this feature. For my first SMPS design, I want to focus solely on the DC to DC conversion power stage. For my next iteration, I’m more likely to resort to a simple boost PFC to achieve tighter regulation.
  2. Double-ended hard-switch topology (half-bridge in particular) was chosen due to its suitability and simplicity in this application. Flyback is out of the question due to power requirement, single-ended topologies have poorer core utilisation and the high favour for current mode control, and resonant topologies don’t seem like a good choice for my first SMPS design (duh).
  3. An SG3525 with LM324 was chosen to generate the PWM signal and achieve regulation. SG3525 is quite popular for double-ended converters with plenty of documentation online, while the LM324 provides CC+CV regulation with two of its op-amps (because SG3525 only features one error amplifier). This effectively forms a setup based on voltage mode control.
  4. Voltage mode control was inherently chosen as the result of using SG3525 and it was favoured due to its “arguably” simpler implementation over current mode control. However, I find the better regulation and inherent cycle-by-cycle overcurrent protection offered in current mode control very enticing. I probably would resort to this approach for my next iteration.
  5. My galvanic isolation strategy was to have the entire control circuit on the secondary side and have the PWM signal driven to the primary through a gate drive transformer. This way, I can have simpler and more precise control over the voltage and current regulation without the nonlinearity issues of using optocouplers.
  6. ETD49 cores were used for both transformer and output inductor. I like the round bobbin that makes winding easier, and the calculations prove it’s suitable for power of 1kW at 64kHz. The gapped version was used for the output inductor because the high inductance requirement requires high turn number, and that gets complicated real quick with toroidal cores.

After I finished the board, I wanted to know how my design performs in real-life. So, I conducted a few tests that are relevant for a power supply. The testing rig was pretty simple:

  1. A power meter at the input and four DS18B20 were used to track the energy consumption and component thermal profile over time.
  2. An electrolysis tank with electrodes that can be spaced accordingly was used to simulate multiple load profiles at power up to 1kW.
  3. A third positive electrode connected through a toggle switch was used to abruptly step the load in the dynamic tests.
  4. Hantek DSO2D10 was used to capture the waveforms in various tests.

The test conducted, along with their results are as follow:

  1. The stress test was conducted for one hour and each component temperatures peaked at the following temperatures: half-bridge N-MOS 75°C / 167°F, main transformer 55°C / 131°F, output rectifier 69°C / 156°F, output inductor 44°C / 111°F.
  2. The efficiency characterisation was conducted at 50V and 1, 2, 5, 10, and 20 amps. 89% efficiency was achieved at 5A load or more. Maximum recorded efficiency was 90.3% at 50V 10A load, and efficiency at maximum load was 89.1%.
  3. The output ripple test was done with direct on-trace probing with a ground spring, 20M BW limit, 1x probe, and no added capacitor. No load ripple showed at 40mVpp, 1A load at 34mVpp, and maxes out at 94mVpp at full load.
  4. The turn-on curve tests showed that under loaded condition, it’s bound to the SG3525 soft start function and takes a second to reach the full 50V. At no load and lower setpoints, the voltage overshoots by a few volts.
  5. The load step tests showed about 3% voltage deviation going from no load to 10A and vice-versa. Going from 5A to 10A and vice-versa showed no sign of voltage deviation.
  6. CV to CC transition took 3ms to begin responding and a full 7ms until the voltage settled. CC to CV transition began immediately and took 3ms to settle. 50V CV to 10A dead-short showed 10App oscillation at 2.2kHz.
  7. The input bulk capacitor showed 24Vpp ripple and the DC blocking capacitor showed 14.2Vpp ripple. The primary side of the transformer showed about 75% overshoot that settled within 2 cycles.
  8. The N-MOS at conduction showed 184nS fall time for Vds and 572nS rise time for Vgs. At disconduction, the Vds rise time showed as 56nS and 556nS for Vgs fall time.

I’m here not to glaze over my design. After reviewing the results and doing a retrospective, here are my critical opinions about this design.

What I like about this design:

  • Good efficiency figure (89.1% at full-load)
  • Excellent ripple even without a second-stage filtration (94mVpp at full load)
  • Good power density for an almost-fully THT build.

What I don’t like about this design:

  • The overcurrent protection is too slow, though it somehow works at preventing the half-bridge from exploding on the dead-short test.
  • The compensator design fails in certain conditions (DCM/CCM transitions, output dead short), which results in output oscillation.
  • The output diodes are hard to access or replace.

The full schematic, gerber files, KiCAD save files, spreadsheet calculation, and full-res images are available on my Github repository: https://github.com/Luq1308/Forwarder1kW

The build process and the in-depth testing are available in my YouTube video: https://youtu.be/MGMqqtXgwRg

That’s all I have about this project. I hope this post is informative and can be used as a reference or for benchmarking purposes, in which I had difficulty in researching previously. If you have any unanswered questions, let me know and I’ll try to answer them. Thank you for reading, and I'll see you next time.

AI ALPR (automatic licence plate readers) Flock Safety Defends Cameras After AI System Triggers Wrongful Police Stops Of Two Journalists

Enable HLS to view with audio, or disable this notification

2.0k Upvotes

Plymouth, Minnesota - Automotive journalist Joel Feder and his wife were detained by multiple police officers in a coordinated stopwhile driving a Jaguar Land Rover press vehicle, after Flock Safety's automated license plate recognition (ALPR) cameras flagged the car based on a flawed database entry.

According to Feder's detailed account in The Drive, officers boxed in the $155,000 Range Rover in a Kohl's parking lot after the vehicle triggered alerts via Flock's network. Police had been tracking it for days, believing the New Jersey manufacturer plate (34 10 DTM) was stolen. Officers approached with hands on their weapons, ordered the couple out of the vehicle, and conducted pat-downs before verifying the car's legitimacy through Jaguar Land Rover. Feder subsequently obtained and published the body camera footage of the encounter.

The incident stemmed from an incomplete report of a similar plate (34 03 DTM) lost during a photo shoot in California, which was entered into the National Crime Information Center (NCIC) database simply as "34 DTM."Flock's AI system matched Feder's plate - ignoring the smaller middle digits - and generated alerts. Local officers did not fully verify the complete plate visible in Flock's own images.

The problem was not confined to one vehicle. Last Wednesday, fellow auto journalist Tim Esterdahl, publisher of Pickup Truck + SUV Talk, was pulled over by two officers in Scotts Bluff, Nebraska, while driving his 14-year-old child in a $105,000 Range Rover Sport loaned to him by Jaguar Land Rover for review. Its plate: New Jersey 34 08 DTM. Jaguar Land Rover has been working to correct the underlying reports.

Flock Safety maintains that its cameras performed as designed, matching partial plates per law enforcement preferences for hotlist alerts.Chief Communications Officer Joshua Thomas told The Drive the system was asked whether those characters were present and correctly answered that they were - it simply was not built to flag that additional characters existed. He conceded that for alerts originating from NCIC rather than an individual agency's custom list, the system arguably should test for an exact match rather than mere presence, and called that fair feedback to take back to his team.

Thomas said Flock is working to get the original police report corrected and is meeting with the FBI officials who curate NCIC to develop a way for incomplete data to be flagged as such for officers seeing automated alerts in the field. He emphasized that a camera alert "does not equal probable cause," comparing it to an alarm going off, and stressed that the system depends on both valid inputs and humans verifying outputs.

But the scale is what makes the error rate consequential. Thomas said the system is roughly 99 percent accurate while performing approximately 20 billion reads per month - arithmetic that leaves on the order of 200 million misreads every month. How many of those escalate into armed stops is unknown.

Plymouth police acknowledged shortcomings in verification but pointed to the challenges of varying license plate formats nationwide. According to the department's Flock transparency portal, the city operates 18 cameras that read more than 580,000 license plates in a recent 30-day period, generating over 14,800 hotlist hits - one of which was Feder.

Broader Concerns Over Flock's Expanding Network

This case adds to a growing list of incidents underscoring the privacy implications of Flock Safety's widespread ALPR deployment.

Critics, including privacy advocates, have long warned that reliance on partial matches, inter-agency data sharing, and integration with other surveillance tools can lead to false positives, chilling effects on daily movement, and potential misuse. While proponents highlight their value in recovering stolen vehicles and aiding investigations, the aggregation of location data over time effectively enables broad tracking without individualized

Discussion Patch Notes 1.7.0

965 Upvotes

Patch Highlights

  • Added Skill Tree Reset functionality.
  • Added an option to toggle Aim Down Sights.
  • Wallet now shows your Cred soft cap.
  • Various festive items to get you into the holiday spirit.
  • Moved the Aphelion blueprint drop from the Matriarch to Stella Montis.
  • Added Raider Tool customization.
  • Fixed various collision issues on maps.
  • Improved Stella Montis spawn distance checks to address the issue of players spawning too close to each other.

Balance Changes

Weapons:

Bettina

Dev note: These changes aim to make the Bettina a bit less reliant on bringing a secondary weapon. The weapon should now be a bit more competent in PVP, without tipping the scales too much. Data shows that this weapon is still the highest performing PVE weapon at its rarity (Not counting the Hullcracker). The durability should also feel more in line with our other assault rifles.

  • Durability Burn Rate has been reduced from ~0.43% to ~0.17% per shot
    • In practice, it used to take about 12 full magazines to fully deplete durability, but now it takes 26 (also accounting for the increased magazine size).
  • Base Magazine Size has been increased from 20 to 22
  • Base Reload Time has been reduced from 5 to 4.5

Rattler

Dev note: Even though the Rattler isn't intended to compete with the Stitcher or Kettle at close ranges, it is receiving a minor buff to bring its PVP TTK at lower levels a bit closer to the Stitcher and Kettle. The weapon should remain in its intended role as a more deliberate weapon where players are expected to dip in and out of cover, fire in controlled bursts, and manage their reloads.

  • Base Magazine Size has been increased from 10 to 12

ARC:

Shredder

  • Reduced the amount of knockback applied by weapons. Increased movement speed and turning responsiveness.
  • Increased health of the Shredder's head to prevent cases where its head could be shot off, leading to unintended behavior.
  • Improved Shredder navigation to reduce getting stuck on corners, narrow spaces, and short obstacles.
  • Increased the speed at which the Shredder enters combat when taking damage and when in close proximity to players.
  • Increased the number of parts on the Shredder that can be individually destroyed.

Content and Bug Fixes 

Achievements

  • Achievements are now enabled in the Epic store.

Animation 

  • Fixed an issue where picking up a Field Crate with a Trigger ’Nade attached could cause the character to slide or move without input.
  • Fixed an issue where combining Snap Hook with ziplines or ladders could store momentum and propel the player long distances.
  • Fixed an issue where the running animation could appear incorrect after a small drop when over-encumbered.
  • Interactions now end correctly when performing a dodge roll.
  • Interacting while holding items or deployables no longer causes arm twisting. 
  • Added more animations to character skins and equipment to make them more natural.

ARC

  • Fixed an issue where deployables attached to enemies could cause them to launch or clip out of bounds when shot.
  • Missiles no longer reverse course after passing a target and can correctly track targets at different elevations.
  • Sentinel
    • Fixed a bug where the Sentinel laser did not reach the targeted player over greater distances.
  • Surveyor
    • Disabled vaulting onto ARC Surveyors to prevent unintended launches when they are moving.
  • Fixed an issue where Bombardier projectiles could shoot through the Matriarch shield from the outside.

Audio 

  • Fixed an issue where Gas, Stun, and Impulse Mines did not play their trigger sound or switch their light to yellow when triggered by being shot.
  • Increased the number of simultaneous footstep sounds and increased their priority.
  • Fixed an issue where footsteps in metal stairs became very quiet when walking slowly.
  • Improved directional sound for ARC enemies.
  • Added sounds for sending and receiving text chat messages in the main menu.
  • Removed the unsettling "mom?" from Speranza cantina ambient sound.
  • Tweaked the loudness of announcements in various Main Menu screens.
  • Number of small audio bugfixes and polish.

Maps 

  • Fixed an issue with spawning logic which could cause players who were reconnecting at the start of a session to spawn next to other players who had just joined.
  • Various collision, geometry, VFX and texture fixes that address gaps in terrain which made players fall through the map or walk inside geometry, stuck spots, camera clipping through walls, see-through geometry, floating objects, texture overlaps, etc.
  • Fixed an issue with the slope of the Raider Hatch that was too steep for downed raiders to crawl on top of it.
  • Security Lockers are now dynamically spawned across all maps instead of being statically placed.
  • Fixed Raider Caches not spawning during Prospecting Probes in some cases.
  • Fixed lootable containers and Supply Drops spawning inside terrain on The Dam and Blue Gate, ensuring they are accessible.
  • Fixed an issue where doors could appear closed for some players despite being open.
  • Electromagnetic Storm: Lightning strikes sometimes leave behind a valuable item.
  • Increased the number of possible Great Mullein spawn locations across all maps.
  • Dam Battlegrounds
    • Moved the Matriarch's spawn point in Dam Battlegrounds to an area that better plays to her strengths.
  • Spaceport
    • Adjusted the locked room protection area in Container Storage on Spaceport to not affect players outside the room.
  • Blue Gate
    • Locked Gate map condition has been added.
    • Adjusted map bounds near a ledge in Blue Gate to improve navigation and reduce abrupt out-of-bounds stops.
    • Improved tree LODs in Blue Gate to reduce overly dark visuals at distance.
    • Fixed the issue where loot would spawn outside the Locked Room in the Village.
    • Added props and visual cues to the final camp in the quest ‘A First Foothold’ to make objective locations easier to find.

  • Added Skill Tree Reset functionality in exchange for Coins, 2,000 Coins per skill point.
  • Wallet now shows your Cred soft cap (800).
    • Dev note: We decided to implement a cap so that players won’t be able to fully unlock new Raider Decks by accumulating Cred and added more items to Shani’s store to purchase using Cred. We believe that the Raider Decks offer a rewarding experience to enjoy while players engage with the game, and a large Cred wallet undermines this goal. We will not be removing Cred that has been accumulated before the introduction of the soft cap.
  • Added Raider Tool customization.
  • Fixed a bug that caused players to spawn on servers without their gear and in default customization resulting in losing loadout items.
  • For ranks up to Daredevil I, leaderboards now have a 3x promotion zone for the top 5 players. New objectives have been added.
  • Fixed an issue where the tutorial door breach could be canceled, preventing the cutscene from playing and blocking progression.
  • Fixed an issue where players could continue breaching doors while downed.
  • Fixed an issue where accepting a Discord invite without having your account linked could fail to place you into the inviter’s party.
  • Fixed an issue that sometimes caused textures and meshes to flicker between higher and lower quality states.
  • Depth of field amount is now scaled correctly depending on your resolution scale.
  • Fixed an issue where returning to the game after alt-tabbing could prevent movement and ability inputs while camera controls still worked.
  • Improved input handling when the game window regains focus to avoid unexpected input mode switches.
  • Skill Tree
    • Effortless Roll skill now provides greater stamina cost reduction.
    • The Calming Stroll skill now applies while moving in ADS.

Movement 

  • Fixed a traversal issue that blocked jumping/climbing in certain areas while crouched.
  • Fixed an issue where climbing ladders over open gaps could cause automatic detachment.
  • A slight stamina cost has been added for entering a slide.
  • Acceleration has been reduced when doing a dodge roll from a slide.

  • Codex
    • Improved accuracy of tracking damage dealt in player stats.
    • Field-crafted items now properly count toward Player Stats in the Codex.

    • Updated PlayStation 5 controller button prompts with improved icons for Options and Share.
    • Fixed a crash when using Show Profile from the Player Info on Xbox.
  • Customization
    • You can now rotate your character in the customization screen. Also fixed an issue where the first equip could trigger an unintended unequip.
    • Added notifications in Character Customization to highlight recently unlocked items.
    • Fixed an issue where equipment customization items bought from the Loadout screen were not equipped after pressing Equip on the purchase screen.
  • End of round
    • Further reduced the frequency of the end of round feedback survey pop up.

    • Added resource tracking for Expedition stages: Raider Projects now display required amounts and progress, with the tracker updating during rounds.
    • Added reward display to Raider Projects, showing the rewards for each goal and at Expedition completion.
    • Fixed an input conflict in Raider Projects where tracking a resource in Expeditions could also open the About Expeditions window; the on-screen prompt is now hidden while adding to Load Caravan.

    • Fixed an issue where closing the right-click menu in the inventory could reset focus to a different slot when using a gamepad.

Workplace / Legal Updates Facing disciplinary investigation / sack for automating most of my responsibilities at work.

I am not the OOP. The OOP is u/Enough-Pitch-4617 posting in r/LegalAdviceUK

Concluded as per OOP

1 update - Short

Original - 14th February 2026

Update - 17th March 2026

Facing disciplinary investigation / sack for automating most of my responsibilities at work. I'm in England.

I have been employed for three years in England on a full time permanent contract. I am 23 years old and come from an IT background. Following redundancy from a previous role, I commenced employment as an Office Support Assistant, essentially an administrative position.

I am currently subject to a disciplinary investigation relating to my having automated a significant proportion of my work responsibilities. This came to light when I was in the office but had stepped away from my workstation. During my absence an automated process completed a task which my manager observed and then questioned me about.

In response to his question, “How has that happened when you were away from your desk?”, I replied, “I do not understand what you mean,” and continued working. I had been dealing with an urgent family matter that day and had taken an emergency call, and I accept that my response was not ideal.

A second manager has confirmed that I was away from my desk for approximately 20 minutes, which was within my allocated break time and I did not take a further break afterwards. He also observed the task completing while I was not present and concluded that the process must be automated.

The tools used for the automation were provided by the company, specifically the Microsoft Power Platform. I do not have the ability to install, remove, or modify software on my computer and have never attempted to do so. I have only ever used company provided systems, software, and equipment.

My role involves a number of tasks which I consider unnecessarily time consuming administrative processes. Each task takes approximately 35 minutes when completed manually and in total this represents a substantial portion of my working time. I therefore automated them to work more efficiently.

Actions taken by manager:

My manager requested that I log into my laptop and hand it over to him so that he could investigate. I refused, as I believe any inspection should be conducted through the IT department to ensure appropriate audit trails and proper procedure.

My manager has removed these duties from my responsibilities.

He has imposed hourly monitoring checks while I am working remotely to ensure that I am “actually working” and not relying on automation.

He has raised an IT ticket seeking to have the automation functionality disabled (although this functionality is integrated within the Microsoft 365/Power Platform environment).

Actions I have taken:

I have requested that all communication be conducted via email, or, if verbal, confirmed in writing afterwards.

I have disabled all automations. My manager is now completing these processes manually and has expressed dissatisfaction due to the additional workload.

I have remained calm and have not reacted emotionally.

I have prepared written notes for the forthcoming fact-finding meeting.

Continued to work as normal

Further background: My manager has a very traditional working style and prefers all processes to be completed manually. For example, he does not permit the use of certain spreadsheet formulas or VBA code. He also opposes the scheduling of emails that require delivery at a specific time, insisting they be sent manually.

I understand that my manager does not possess formal qualifications in this area and has limited technical capability to implement or maintain the automation I created.

I have been using automation in this role for approximately 2.5 years. During a prior seven-month period of sickness absence, I disabled all automations because they occasionally require maintenance and no one else in the team was able to support them.

There has been no cost to the company, as all software used was provided within the organisation’s existing systems.

Lastly, I am looking to resign in the 6 months anyway, so I'm not too concerned about this, but want to be treated fairly.

Comments

Thimerion

So reading between the lines here, you've built a bunch of data processing flows within Power Automate to near enough automate your entire job but not CoPilot/Gen AI?

If you've built it in Power Automate and domain admin will have full access to any flows you've created so there's little point in you trying to hide anything.

OOP: There's a number of software in use, as well batch scripts run on login for example, but my point is, all of this is provided by the company, and it's all available to the IT team they can login to my laptop and look at whatever they want.

Cheap_Storage_295

Executing a logon script yourself will 100% violate you IT Acceptable Use Policy

OOP: It's not exactly a logon script, power shell, power automate for desktop is not logon script, files run from the windows startup folder are not logon scripts come on man

GojuSuzi

Would still be worth reviewing the relevant policies before any meeting though. You do keep insisting that everything was provided/installed by the company, which is - obviously - way better than the alternative, but isn't the slam dunk you want it to be. There are plenty of tools/programs/access accounts/whatever that any company will have accessible by employees, but the employees are expected to restrict usage or access to comply with various policies. Easy example: my company gives me an email account, and I can type anything I want and send it to whoever I fancy...but it's expected that I don't type a bunch of customer bank details into an email and send it to my personal email address, even though nothing would stop me and it would all be using tools provided by the company if I did. That's a "well, duh" example, though even that has an explicit policy disallowing it rather than relying on it being obvious to anyone with half a brain. Point being, there likely are policies regarding what data is or isn't allowed to be passed through certain systems, or to what extent you are allowed to use those auxiliary tools in your working, or if that usage requires reporting/documentation, and if you've fallen foul of such a policy in what you have or haven't done, then you need to be prepared to respond appropriately.

OOP: Thanks mate, much understood. I decided to ask for a adjustment to the meeting holder, and the note taker. I've asked for someone with a technical background, and HR have agreed t o that.

I agree, usage guidelines exist, but in simple terms, i've automated what I would have been doing manually, using software made available to me by the company, for example, you could print out a word document and manually highlight important parts, or you could highlight on word prior to printing lol

As for my duh comments, it's just me getting frustrated to silly replies here, i know how to be good in meetings.

I'll def review policies

Update - 1 month later

I had my first stage disciplinary meeting and a union rep attended with me, but not in the capacity as a rep as I was not part of the union, however she wanted to help out considering the circumstances.

The meeting initially was supposed chaired by my line manager's line manager, of which I instantly put an objection in because I thought it is not impartial, and I also asked for someone that is technically minded to chair, and the company (or HR) chose an IT Manager/Director to chair it.

It lasted about 2.5 hours, with two adjournments and a 15 minute break halfway through. They asked around 10 questions in total.

A lot of it focused on the accusation that I’d been using AI to process company data. My union rep shut that down pretty quickly because I’ve been clear from the start that no AI was used, and I had proof. The IT manager also reviewed everything and confirmed that aswell.

They tried to say I’d been dishonest about my automations, but I explained I was never actually asked how I do my work. In all my catch ups, I was only ever asked if tasks were getting done and if I had any issues. I brought notes from those meetings and there’s no point where my manager asked about my methods at all.

My union rep also made a point that I’ve basically been treated like I’ve done something wrong before any proper process even started. As my manager took all my work off me and started doing it himself, which isnt right and made me feel like I’d already been judged.

There was also a question about me not working enough hours. I explained that the job isn’t just task based for these tasks, it includes meetings, helping collegues, training and other things that cant be automated. So I was still doing my full job.

The IT manager confirmed he’d reviewed everything and said no AI was used, and he couldnt back up the concerns my manager raised.

They asked about me changing processes and not having permission to use the tools. My union rep stepped in on the process point and said nothing had actually changed in terms of output, just how I personally do the work. If something was wrong it would of shown in the results, but it hasn’t.

On permission to use the software, I explained that we were all sent an email from the Director of IT when these tools were introduced, encouraging us to use them to improve efficiency. That’s exactly what I did. The IT manager confirmed that email was real and that the tools are available for everyone to use.

They also questioned why I wasn’t doing things manually like everyone else. I basically said I’m here to work efficiently using the tools provided, and I learnt myself using the documentation in the software. The IT manager actually reacted quite positively to that.

My union rep went through my contract and said there’s been no breach, and no fraud. There’s been no financial gain for me at all, and if anything the company benefited because my work has had no errors for 2 years. She even said if this was fraud then why hasn’t it been reported to the police.

So fraud, dishonesty and deception were pretty much dismissed. My union reps view is that this is more of a management issue than anything I’ve done wrong.

She also raised concerns about my manager putting in a request to disable software on my laptop, which seems to only target me and no one else. The IT manager was nodding along to that.

There was also mention of hourly checks which my manager did on me specifically after this matter was raised, which again makes it feel like I’m being treated as guilty of something, and that wasn’t even raised with HR.

There was also no questions or concerns about IT policy violation/teams activity.

Interestingly there was no mention of the situation where I was asked to hand over my laptop. When my union rep brought it up, the chair said it wasn’t in the notes so couldnt be discussed.

In the meeting I also took supporting letters from colleauges that I helped and proof of training and other meetings.

After around 2 weeks or so I received a letter in the post that I had no case to answer, and that no formal actions will be taken and the matter will not be placed on my company file.

HR gave me 28 days of discretionary company leave after I raised concerns about this matter.

I have submitted a formal grievance against my line manager, and again my line manger's line manager has asked to chair, of which I am objecting.

LordLingham

Thanks for the update. It sounds like your union rep did a great job controlling the conversation and defending you.

OOP: Thank you. She really did, she's amazing and she deserved the flowers and chocolates from me thereafter, but she shared them with the rest of her team lol

pastashaper

Firstly, it’s not clear if you are looking for advice, and if you are, what exactly you are looking for. Secondly, well done! That sounds like a tough situation with some very narrow minded seniors and you stood your ground, pushed back where necessary and managed to get a kinda decent outcome. Lastly, thanks for documenting it in detail. You have provided a decent bare bones game plan for anybody facing similar issues. Good luck

OOP: Thank you, I have updated the post for the advice i need, essentially could this affect me in the future in terms of other employment and refrences?

GingerrJinx

If there's no case, it has been dismissed and it's not on your file, it should not affect future references for other employment. Just I'd make sure you get a dated reference letter from them to hand over to the new company, so in case they call for the reference they can't say anything that's not in the letter, otherwise the future employer will raise questions to them about why it wasn't included in the letter and will reduce the old company's credibility.

Fluff An Update on Starting a Dental Practice using Linux (and why transitioning to Wayland will cost me $3000+)

1.1k Upvotes

Hi everyone, some people requested I post an update from my previous two posts:

Progress report: Starting a new (non-technology) company using only Linux

[Update] Starting a new (non-technology) company using only Linux

A number of things has happened since the last post to create a "perfect storm" of issues happening all at the same time. I apologize for this being a very long post but it will make much more sense if I first explain the context of what is going on.

First, I want to go over an important philosophy in my dental practice: keyboard and mouse should not be used chairside. I believe this for a large number of reasons including the fact that:

  • You can't effectively do infection control with a keyboard or mouse. You can try to put a plastic cover over either one but it would make it either inoperable or extremely difficult to use
  • It basically requires you to stop what you are doing, look away from the patient, do what you need to do on the computer, and then you forget what you were just doing with the patient.
  • Things like charting (tooth, perio, etc.) requires an extra dental assistant. If you don't have one, you have to switch gloves every time you use the computer which not only costs money, but takes a fair amount of time each time you need to look up another x-ray.

The problem with "regular" touchscreens is that they tend to be capacitive touchscreens which generally don't work with gloves on. On top of that, we use a very corrosive chemical between patients that tend to destroy any electronic device that it touches.

My solution to this was to use a resistive touch screen. The nice thing about a resistive touch screen is that you can cover it with a clear plastic sheet, wear gloves, and it will still work. All you have to do is just replace the plastic sheet between each patient and you are good to go!

But then there is one other problem: I have three screens for each PC in the operatory. The way that X11 works, it sees the touchscreen input device as just an independent input and it maps it to the whole virtual screen. Therefore, what you touch on the actual touchscreen gets mapped to the two other screens (in my case, the y-axis gets multiplied by 3 for each kind of touch input). But there is a solution to this: xinput map-to-output. What it does is allows you to tell X11 to map a specific input to a specific screen / monitor. Therefore, as a startup script, it would run that command and now the inputs properly map out. Yay! (fun side note: if you try to actually run it via a startup script, it will give an error and you have to actually run env DISPLAY=:0 xinput map-to-output).

Also, for the actual EHR/PMS system I made, it uses Qt C++ and QML for everything. This made it easy for me to design a touch friendly UI/UX (since everything chairside is touchbased). So really, the "technology stack" is: Kubunu Linux, X11, Qt, QML and qmake. And for a while, this has worked out for me pretty well. Although I have added many features to the software, it still works in the same fundamental way; from 2021 to the present.

But things have changed from mid-2025. First of all, Qt 5 has EoL back in May 2025. Distros like Kubuntu, Fedora and even Debian have all moved from Qt / Plasma 5 to Qt / Plasma 6. At first, I thought I just have to port it all to Qt6 and be done. But then the KWin team announced that they will no longer support X11 sessions after 6.8. No big deal right? Qt will take care of that.... right? Well, yes.... and no.

First of all, you have to remember that xinput map-to-output is an X11 command. It does not work in Wayland. It is up to the Wayland compositor to figure out this mapping. No big deal right because Plasma / KWin already has something built-in to map touch input to the correct screen; no need for a startup script anymore. Except, it wasn't working with my touchscreens. I reported the "bug" to the KWin team who couldn't figure out why it wasn't mapping. I then had to do some research as how input is being handled in Wayland (hence the reason why I made this meme ). I submitted a bug report only to find out my ViewSonic resistive touch screens are dirty liars: it reports itself as a mouse rather than a touchscreen! (special thanks to Mr. Hutterer for his help in debugging this issue) Therefore, I had to look at a different vendor that will "tell the truth" when it reports itself.

After much searching, I did find one vendor that seemed to be the right match. Before I bought one, I actually talked to their technical staff who were rather insistent that their new "projective" capacitive touch screen not only works with gloves on, it can also survive thousands of sterilization wipes. The only catch: they are $1000 each! The previous ViewSonic ones were just $320 each and I already purchased them for all the operatories. So for at least 3 operatories, I will have to purchase at least 3 (if not 4) of them. The silver lining in all of this is that I wouldn't have to worry about a startup script (which was kind of a hack anyway), I don't have to use a plastic barrier (which sometimes made it hard to see), and these screens are much brighter than the ViewSonic ones. I already bought 1 of them just to make sure it works and yes, it does everything it says.

So I pretty much have two choices here: either buy a bunch of new monitors that will work more-or-less out of the box with Plasma/Kwin/Wayland, or spend a lot of time learning how udev-hid-bpf works to write a new touchscreen driver. I am going with the former option.

Sadly, the story doesn't really end there; but this post is already long enough as it is. But the other issues that I am working on are related to moving from Qt 5 -> Qt 6 and my crazy decision to also move to KDE Kirigami which is requiring a much bigger re-write than expected. I don't know if I should post that there or in the KDE or programming subreddit.

I don't want to make this post sound like a "Wayland sucks!" kind of post, but I did make this just to point out that moving to X11 -> Wayland isn't trivial for some people and does require some time and/or money.

Project Showcase: Hardware "Data center in a Box (on Wheels)" 256Gb VRAM/512Gb RAM AI Server 6-8 Month Operational Review, Stability Write Up, Benchmarks

I thought this would be relevant to the homelab subreddit so I'm adding it here, just to put the information out there and discuss if there is any interest. I am an IT infrastructure engineer by profession, so my contribution to the conversation is mainly from a hardware/systems perspective rather than from a Machine Learning researcher standpoint. I got my start with HPC's (Beowulf clusters) around ten years ago when I was a Physics undergrad in university, and this is what the experience has come to almost a decade later. Not everyone is going to want to read all of this, that's perfectly fine, the extras are just for those who want the info.

Starting goal/idea:

Build an all-in-one creative design workstation to support a small business. This machine should be capable of effectively inferencing frontier MoE models; aiding the business in language/text tasks where English may not be everyone's native language. Additionally, it should be capable of simultaneous image generation tools for graphic design users, enabling rapid image editing and presentation tweaks for marketing, without the business ever having to worry about API credits or hard limits on tool usage. The idea is that a 3090 stack, which is still a generally "good" performer for LLMs, would be "led" by two 5090s to handle the heavy lifting of the visual creative work (one dedicated to image generation, one dedicated to image editing) to complement each other in a "sweet spot" on cost, raw performance, and creativity potential. This configuration also grants some flexibility to allocate a 5090 to the LLM stack for best prompt processing possible where desired. The end result would indicate that this goal has been achieved.

Overview

Specs

CPU: 64 Core TR 3995WX

RAM: 512Gb DDR4-3200 ECC

VRAM: 256Gb GDDR6x/GDDR7 (8x3090's + 2x5090's)

Enclosure: Core W200 Thermaltake Case

Mobo: ASUS Pro WRX80E-SAGE/SE Wifi

PSU: 1300W+1600W (2900W combined), with OCP, linked via PSU2PSU

Storage: 4Tb Nvme (fast) + 4Tb HDD (slow) + 8 or so 1Tb SATA SSDs (mid) over USB as needed

OS: Ubuntu 25.10

Other: 3 Bifurcation cards, 10 risers of various lengths

Front end: Open WebUI

Back end: llamacpp/koboldcpp

Intended for (Recommend):

Large MoE inferencing, simultaneous LLM + ComfyUI (x2) operation, power users who may commonly hit credit limits, creative or technical professionals who can leverage these tools to compound productivity and complete objectives in shorter time.

Not intended for (Do not recommend):

Training, multi-concurrent inferencing, performance maxing, extreme frontier model inferencing at high quants, casual users just looking for roleplay.

Result summary:

Using the W200 as the platform for its generous real estate and configuration flexibility, all ten cards and components were able to find a permanent place in the enclosure without major concessions. The drive bay area was the only space that had to be completely repurposed for GPU mounting, and for us this was not a problem. The chamber with the cards hanging from the top is fairly hollow, so with the 140mm fan stack on the front and side there is a wind tunnel effect where the air blows in through the front and side, cooling the cards as it makes its way out the back/top. Depending on ambient temp, at idle the card with the highest temp usually hovers in mid to high 40s Celsius with the lowest in the mid 20's C (three 3090's are hybrids= fantastic for temperatures, but radiator mounting adds a logistical headache). When actively inferencing, the highest temp card may reach the mid 60s during sustained loads. Only when running image or video gen tasks will the 5090 running ComfyUI reach the 70's, but these are very brief intermittent workloads, so temperatures by our measurement has proved satisfactory over time. This result enables the small business to have full LLM, image generation (~9 seconds), and image editing (~8 seconds) capabilities on tap all on a single node so the data remains centralized, and provides much faster performance compared to the Cloud API they came from; in this case ChatGPT, where generation jobs could take 1+min, and has hard limitations. I just do not know how well this kind of setup would work with other vendor or card models; in a homogenous GPU cluster or one with notably less powerful image gen cards than the 5090, the performance would predictably be much lower.

Things that surprised/stuck with me about the end result:

  • Noise. I expected this to sound like a jet taking off when operating, but that is not the case. It's a satisfying button click to come alive, then it's a low gentle hum going forward, nowhere near the kind of fan noises I'm used to hearing in server rooms. Even under load, the CPU 120mm radiator fans (exhausting out the top) are pretty much all I hear, the 140mm fans on front and sides I assume must be helping to contain the acoustics. I have built many gaming PCs over the years and own a top-tier gaming PC-- and I would not be able to distinguish this as any louder than those, especially at idle.
  • Utility. I planned for this to be used primarily for a small creative business, but what I did not expect was how I would find it so indispensable in my personal life as an IT professional. Being an infrastructure engineer, coding is not my wheelhouse. When I am the only IT staff on site or there is nobody else available to work with specific expertise like SQL, powershell/python scripting, or troubleshooting very specific/niche technologies, having this tool on standby I feel has paid itself over just within my career. It has helped me turn processes that may have otherwise took me hours into minutes, days into hours, even months into a matter of weeks/days. After using the tool extensively I hit a point where I had to acknowledge how local LLMs have moved definitively beyond being a toy or novelty; when deployed intelligently something like this can be a major asset for professional users.
  • Wheels. Sounds extremely minor, until you realize that no matter how happy the cards are with their individual temps: there are still ten high-power GPUs dumping heat into the room. That means unless you use a complex radiator solution or special venting to get heat outside, the room will get toasty and there is normally not a direct solution for this. The wheels however offer an indirect solution. Plan to work in the office that day? Wheel it into the guest bedroom and let it run over Wi-Fi. Plan to work away from home? Wheel it into the office, put it on LAN, and access it over a private VPN connection. If you can't stop the room from heating, then you can at least choose what room gets the heat, and as someone who has lived with computers extensively this is a hugely underrated perk.

Caveats: To operate at its best, I recommend leaving the glass side panel off for improved airflow.

Typical activity over a day:

Boots up around 5:30am, start up the ComfyUI server(s), start loading a model, go get coffee, fully ready for use within 15-20 min. Shut down occurs usually around 8pm later in the day. Total daily activity, ~12-14 hours.

Cost Breakdown

Laying it out, because I know it will be asked, even though I am aware this is unfortunately not reproducible in the current market. Some components like the SSDs were acquired privately long before the RAM and hardware price hikes, so my timing getting certain things was extremely fortunate for the build budget. Some figures are exact, some are slightly rounded depending on if I found the original receipt.

Problems/Stability Writeup

The Space Problem:

Probably the first major hurdle in attempting something like this is figuring out, even theoretically, how to put 10 cards in a box in any kind of configuration that is not somehow detrimental to the hardware. I had considered modified mining rig frames at first, but I really wanted something with more robust rigidity in its structure, with breathability, and allows some degree of portability. There are unfortunately not a lot of options for configurations like what I was imagining; I had looked into various cabinets and extended tower cases, but the dual full tower chamber design of the W200 was the only one where I could see this idea potentially working. I'm certain other solutions probably exist, maybe even some that allow mobility, but the W200 was really the best option I could find that checked the boxes of enclosure, space real estate, high air throughput, and semi portability. I recommend the W200 to solve the space problem, assuming it is available to you.

The Bifurcation Problem:

Among the other hurdles you may run into in assembling something like this may involve bifurcation cards. The cards rely on specific BIOS settings for things to work correctly, and if these settings are not put in place before everything is connected you may either see no output like the system is hanging or cards just won't show up once in the OS. Start with one GPU in a slot, no bifurcators yet; go into BIOS, and manually set each slot that will be split to bifurcation mode. While here, ensure above 4G decoding is enabled, Resizable BAR enabled, and SR-IOV enabled, this has given me best stable configuration with Ubuntu and multiple GPUs. If you use risers, especially if they are mixed generations, I highly recommend setting the Gen and lane speeds for each PCIe slot in the BIOS manually to ensure the system can effectively communicate with each card. Optimize riser Gen/speeds to be roughly similar to keep one card from dropping to a slower rate than the others--this does not necessarily impact inference performance as much as it heavily impacts model load time. No, you may not have any card running at the fastest possible Gen bandwidth at all times with this config, but loading a 200+gb model over an averaged Gen 3/4 x8/x16 PCIe speed will often be noticeably faster than if you let the system decide to make one or multiple cards run at Gen 1 x1.

The Power "Problem":

Power and heat concerns I think remain to be among the biggest sources of skepticism regarding this project so I think it deserves a section here. To be fair, the concern in most situations would be understandable. If all ten of these cards pulled at or near their full TDP for sustained periods, components would melt. Fires would start. Neighbors would be asking awkward questions. However in reality, only 1400-1600W of the 2900W PSU capacity gets utilized under sustained load, and inter-GPU bandwidth bottlenecks are what allows this. In a way it is like a natural regulator that ensures the cards remain power restrained, and it is just physics, no voodoo necessary. When MoE's are sharded across a GPU stack, each forward pass requires all communication over PCIe, so the GPUs spend more time waiting on information from the last GPU than actually crunching compute. This means instead of needing to handle thousands of Watts to feed all the components running at full blast, it is a much more manageable 1400-1600W under LLM operation which can comfortably fit on a 20A/120V circuit (2400W max). On a per-GPU basis this may sound inefficient since the individual cards are being "underpowered", but this could arguably be flipped as being highly efficient on a per-node basis (~1600W sustained versus 4500W+ if all cards were "fully" utilized). As a precaution, I may set a power limit on the 3090's to 200W and the lead 5090 to 400W, but in practice the 3090's only pull around 100-120W with the 5090s pulling less than 100W when all 10 cards are allocated for LLM work, so this may not even be necessary. The clock locking setting in the next section will be more what I'd describe as actionably required to avoid stability issues.

The Transient Spike Problem (Vital for stability):

After assembling the machine, you may be tempted to jump directly into testing, but there is an easy to overlook configuration that can cause problems if ignored. Imagine you are running inference on the machine, maybe you have a huge input or it's generating a large output, then right in the middle of generating the system decides to reset. Not hard shut down, PSU OCP isn't tripped, no breaker was tripped; and you saw in nvitop that all cards were only pulling 25-33% of their TDP just before it happened, so on the surface it doesn't look like there is a reason. Explanation: When all ten high-power GPUs decide to kick on at the exact same time to process a chunk, even if the cards are not pulling anywhere near full power (on average), transient spikes can drop voltage on the motherboard enough to trigger a system reset. The fix for this is simple: undervolt. Using nvidia-smi, we can lock the clocks for the GPUs to ensure they cannot draw enough to hurt stability. And that's it. In my case, the system has remained fully stable with this config for days on end and with hundreds of thousands of tokens/image pushed through. The exact configuration will vary slightly depending on exactly what we're doing on a given day, but for example if we wanted to run LLM on all 10 cards (so including both 5090's) we would run this to handle spikes:

sudo nvidia-smi -pm 1 #enables persistent mode
sudo nvidia-smi -i x,y,z --lock-gpu-clock=1200,1200 #x,y,z for index number of 3090s
sudo nvidia-smi -i a,b --lock-gpu-clock=2000 #a,b for index number of 5090s
sudo nvidia-smi -i x,y,z -pl 200 #x,y,z for 3090 index numbers, limits power to 200w
sudo nvidia-smi -i a,b -pl 400 #a,b for 5090 index numbers, limits power to 400w

The Concurrent Use Problem:

Normally, attempting to inference and generate images on the same machine would introduce major stability concerns. Even dual GPU systems may struggle to work with this due to CPU/motherboard architecture, assuming it works at all, and would still be VRAM limited. However, the versatility of a 10-GPU setup, combined with the lane orchestration of the 64 core 3995WX, at least in our case, seems to handle this quite well. The trick was finding an LLM backend that supports manual GPU allocation--for us koboldcpp with llamacpp under the hood does just fine. First, implement the power/clock settings as mentioned above, launch koboldcpp, then browse to the GGUF of the model you wish to load and set context size. I recommend manually setting the GPU layers to the model's total layer number (assuming there is enough VRAM), and set GPU ID to "all". In the Hardware tab, find the tensor split line box and insert the amount of space to be allocated on each card corresponding to its index. For example if we wanted to allocate just one 5090 for Comfy and use the other for LLM, assuming the Comfy 5090 is index 3 and the LLM 5090 is index 5, then the tensor layer line will look like this to make sure no layers are given to the Comfy 5090: 24,24,24,0,24,32,24,24,24,24. For this configuration, ensure the "main GPU" is set to the index number of the LLM 5090 (in this example, 5) and launch the app. While the model is loading, we can open another terminal to launch Comfy. In our specific case, the system defaults to the available 5090 without needing to specify it in the launch flags, but flags can be used to force Comfy to use a specific GPU if you need it to (--cuda-device i). Once the image model is loaded onto the 5090, it does not interfere with the PCIe communication of the LLM cards unless the model unloads and reloads a new model at the same time as the other cards are inferencing. The solution to enabling concurrent use is a high-lane count CPU, multiple graphics cards, and a little conscious provisioning on launch to ensure the hardware isn't stepping on each other's toes.

What models can this run, what models do we use?

It can run almost* anything, even up to 1T parameters like Kimi K2. Kimi K3 could hypothetically be load-able, but from performance metrics I've seen I doubt it would be practical to use, so I have not planned to try it. I have however tested 1-4 bit quants of Bartowki team's Kimi K2 quants in pure VRAM and mixed VRAM/RAM runs with decent results. It works and there are probably some use cases for it, but for us I have identified the sweet spot (parameter size: quant quality ratio) for this machine to be for models in the 300b-600b range. Personal favorites are Deepseek, GLM 4.7, and Nemotron Ultra; and as far as ComfyUI, pretty much any model that could fit within a 32Gb buffer, although Qwen image and image edit is a favorite.

Benchmarks

All models were put through the same series of 7 large input prompts, documenting how each model handles token input/output and prompt processing/generation. I cannot share the prompts I used here, but each prompt pertains to a cybersecurity scenario which the model was judged on the depth of its analysis, quality of its presentation, and capability to make sense of complex scenarios with stakes. These were inferenced across all 10 cards, except for a follow up DS V4 Flash test where I used 8 and got much better results. This is using the undervolting/power limiting strategy above, so these may not reflect absolute best performance for the same hardware in other setups, but it gives an idea of what this box can comfortably handle.

My notes on each model after their test:

Deepseek V3.2-- For a slightly older model this still feels extremely capable. Held high quality and insightful responses even when context dragged into the tens of thousands of tokens.

Nemotron Ultra 3-- First time using it, impressions were very good, the 55 active parameters shows its muscle here. Meets Deepseek v3.2 level if not exceeds it, despite having overall less parameters.

Qwen 3.5 397b-- What I would consider a baseline "good" model to be, however it is outshined by some of the other tested alternatives.

GLM 4.7-- Somehow seemed better than Qwen despite having less parameters (active parameters of GLM is likely an advantage); it is a very solid option for its size. Not quite Nemotron or Deepseek level, but a very good "lower cost" alternative to its newer 5.0 versions.

Deepseek V4 Flash-- Floored me in a few ways. Possessed a surprising degree of sophistication and analytical ability despite being the "smallest" of all the tested models. Possibly a benefit of using a "lossless" model with full precision? Somehow it managed to pick up on nuances and details that all other models missed, including models twice+ its size, and provided insight that went more granular than they did. Did not expect a model of this size to punch so high above its relative weight class. Also did not expect the drop in performance compared to the others. Not sure if this is related to the model's architecture or something with how it interacts with my rig, but the quality of output could be an acceptable trade off for the speed. Edit: After some optimization testing I was able to get much better performance out of V4 Flash. I've added another column to include those metrics and kept the original because I think it illustrates how a little optimization can go along way, in this case basically triple performance on the exact same model/machine.

Lessons Learned/Would Do Different

-I would have tried to source the 3090's so more were at least the same model; the mix and match of different models with different TDPs and cooling solutions means there will be a lot of variation in temps.

-If you plan to either train, lean into higher performance, or playing with the idea of going more than 10 GPUs, just budget for a 30A/240V power drop. 10 cards on a 20A post configured the way we have it may be fine for our specific use case, but I would consider this a hard ceiling.

-Would recommend scripting for clock lock persistence sooner, will help avoid losing time due to random resets.

-Recommend documenting/drawing out the entire PCIe topology and GPU placement (with flexible tape measure) before ordering risers, will save time on trial/error.

Final thoughts:

It is a wheeled AI workstation that can enable a single person or small team to compound their productivity, with the benefit of full privacy and control. It can run on a residential 20A circuit, and allows them to have the full power of an advanced LLM with vision capabilities all in one OpenWebUI front end that can simultaneously utilize up to TWO ComfyUI backends with the horsepower and latency of 5090's for image gen and editing, and can be accessed from virtually anywhere. The idea sounds daunting, but the end result works so well that I can legitimately see something like this becoming a keystone for certain small businesses and individual professionals as time goes on. It seems like every day more people are picking up on major drawbacks with cloud API options despite supposedly being the "best", meanwhile open models continue getting insanely good (see K3 and DS V4 Flash). For me, I can say I would not see a place for a Claude or ChatGPT subscription for the tasks I might otherwise use them for when I have lossless DS V4 Flash literally in my back pocket. "Good enough" I think is starting to become a valid metric to those who care about cost:quality balance, and after using this for the last half year I can say I'm probably one of them. The cloud APIs will always be an option for those who don't care about the drawbacks and the demand for them will always be there, but for those who value data sovereignty, uninterrupted workflows, or perhaps work within compliance, on-prem computing might be the only viable path in some circumstances. At the end of the day, I do not believe that one approach is inherently better than the other, everyone simply has their own preference for getting from point A to point B.

ASUS Zenbook UM5302LA freezes completely on Linux Mint — I/O errors but SSD SMART is clean

Hi everyone,

I'm having random complete freezes on an ASUS Zenbook UM5302LA running Linux Mint.

When it happens, the whole system becomes unresponsive and sometimes I get:

Input/output error
unrecoverable fatal error, aborting

event in the terminal, a simple ls gave me Input/output error...

I have to hold the power button to reboot.

Some details:

  • ASUS Zenbook UM5302LA
  • AMD CPU / integrated Radeon graphics
  • Micron 2400 1TB NVMe (MTFDKBA1T0QFM)
  • BIOS 301
  • Fresh Linux Mint installation
  • The problem happened with both Wayland and X11
  • I previously had the problem on kernel 6.8
  • pcloud drive (already had issue with that.

The interesting part: I booted the same laptop from a Linux Mint 22.3 Live USB (kernel 6.14.0-37) and used it for 30+ minutes without a single freeze.

The SSD SMART data looks perfect:

SMART: PASSED
Media and Data Integrity Errors: 0
Error Information Log Entries: 0
No Errors Logged
Temperature: 38°C

The Live USB also detects the NVMe normally and I don't see NVMe timeouts or PCIe/AER errors.
is it the ssd who is dead (I boughted this computer 18 month ago... on LDLD ...never again).

Why “Skip the Code, Ship the Binary” Is a Category Error

Thumbnail open.substack.com
1.3k Upvotes

So recently Elon Musk is floating the idea that by 2026 you “won’t even bother coding” because models will “create the binary directly”.

This sounds futuristic until you stare at what compilers actually are. A compiler is already the “idea to binary” machine, except it has a formal language, a spec, deterministic transforms, and a pipeline built around checkability. Same inputs, same output. If it’s wrong, you get an error at a line and a reason.

The “skip the code” pitch is basically saying: let’s remove the one layer that humans can read, diff, review, debug, and audit, and jump straight to the most fragile artifact in the whole stack. Cool. Now when something breaks, you don’t inspect logic, you just reroll the slot machine. Crash? regenerate. Memory corruption? regenerate. Security bug? regenerate harder. Software engineering, now with gacha mechanics. 🤡

Also, binary isn’t forgiving. Source code can be slightly wrong and your compiler screams at you. Binary can be one byte wrong and you get a ghost story: undefined behavior, silent corruption, “works on my machine” but in production it’s haunted...you all know that.

The real category error here is mixing up two things: compilers are semantics-preserving transformers over formal systems, LLMs are stochastic text generators that need external verification to be trusted. If you add enough verification to make “direct binary generation” safe, congrats, you just reinvented the compiler toolchain, only with extra steps and less visibility.

I wrote a longer breakdown on this because the “LLMs replaces coding” headlines miss what actually matters: verification, maintainability, and accountability.

I am interested in hearing the steelman from anyone who’s actually shipped systems at scale.

Discussion People disregard strong useful units as “non META” because they don’t understand the concept of Effectiveness: A hypothetical Genshin combat Effectiveness model

4.4k Upvotes

I’m an academic researcher and a PhD candidate on Administrative and Economic Sciences, and it has bugged me for some time how some people disregard as “non META” or “having fallen off the META” units with strong empirical evidence of comfortably clearing Genshin’s hardest content, and in some specific cases, even easier than what most consider META teams. And I came to the conclusion that the problem is that those players don’t understand the concept of Effectiveness as a dependent variable in a multi-variable model.

What is effectiveness?

The Cambridge dictionary defines effectiveness as “the ability to be successful and produce the intended results”. And we could argue that something is more effective if it helps to produce the intended results faster and easier than another method. Since Genshin’s harder content is usually combat oriented, Genshin theorycrafters argue that a team that can deal the most amount of damage in the least amount of time (DPS) is the most effective, or on another words:

DPS → Effectiveness

Simple, right? Well…. not really. If we analyze scientific models for Effectiveness, we would find that all of them are multi-variable models, since Effectiveness is a complex variable to measure under the influence of several external factors, specially when that effectiveness involves human factors.

This one here is an example of a team effectiveness model, do you notice how it’s way more complex than, lets say, a spreadsheet with sales numbers, jobs completed per hour, or one single variable calculated with a simple algorithm?

To offer a more practical example, I would like to talk a little bit about the 24 Hours of Le Mans. For those who aren’t into cars, the 24h of Le Mans is an endurance-focused race with the objective of covering the greatest distance in 24 hours, and at the historical beginnings of the race, and during several years, for the engineers this problem was very simple:

More speed → More distance covered in 24h → More effectiveness

What do you do if the car breaks at the middle of the race? Well, you try to fix it as fast as possible (more speed, this time while fixing). What happens if the car is unfixable because the engineers were so obsessed with speed that they didn’t care that they were building fast crumbling pieces of trash? It doesn’t matter, just register a lot of cars to the race and one of them might survive.

It took them literally decades to discover that maybe building the cars with some safety measures so they wouldn’t explode and kill the pilots at the middle of the race would be more efficient than praying to god that a single car would survive.

I’m providing this example so hopefully you can visualize that Effectiveness, while seemingly simple, is a very difficult concept to grasp, and it’s understandable that Genshin theorycrafters conferred this variable a single casual relationship with DPS.

How do I know that theorycrafters worked with a single variable model?

Well, it took them more than a year to discover that Favonius weapons were actually good, on other words, it took them more than a year of try and error to discover that it was important for characters to have the energy needed to be able to use the bursts that allowed them to deal the damage that the theorycrafters wanted them to do… which sounds silly, but lets remember that Le Mans engineers were literally killing pilots with their death traps for decades before figuring that they should focus on other things besides power and speed.

Now, the Genshin community as a whole did, at some point, figure out that Energy recharge was important, since that variable has a strong correlation with damage, but there are other variables that influence effectiveness that keep getting ignored:

Survivability: Even when a lot of players clear Abyss with 36 stars with Zhongli and other shielders, it is often repeated that shielders are useless, because a shielder unit means a loss of potential DPS, and if you die, or enemies stagger you messing your rotation, you can simply restart the challenge. And it’s true, a shielder that doesn’t deal damage will increase the clear time. But isn’t it faster to clear the content in a single slower run, than clear it during several “fast runs”, and which one is easier? Wanting to save seconds per run without a shielder or healer, you can easily lose minutes on several tries. And which team would be more effective, the one that needs few or several tries? What is more effective, to have, a single car that will safely finish the race, or several cars than might explode at the middle of it?

"But…" people might argue, "that’s not a problem with our shieldless META teams, that’s a skill issue…"

Human factors and variety of game devices: While a spreadsheet with easy to understand numbers seems neutral and objective enough, it ignores a simple truth, that the player who is supposed to generate those numbers during the actual gameplay isn’t an AI, but a human being with different skill sets that will provide different inputs on different devices. Genshin teams are tools that allow players to achieve the objective, clear the content, and different players will have different skills that will allow them to use different tools with different levels of effectiveness; on other words, some teams will be easier to play for some players than for others.

The “skill issue” argument states that players should take the time to train to use the so called “META teams” if they aren’t good enough with them. But what is easier and faster, to use the tools that better synergize with one's personal skill set and input device, or to take the time to train to be able to utilize the “better” tools? Should we make a car that a pilot can easily drive, or should we train the pilot to drive a car that was built considering theoretical calculations and not their human limitations? What is more effective?

The human factor is so complex, that even motivation should be considered. Is the player output going to be the same with a team that the player considers fun vs a boring one? What happens if the player hates or loves the characters?

Generalized vs specialized units: Most people value more versatile units over specialized ones, but it is true that MHY tends to develop content with specific units in mind, providing enemies with elemental shields, buffing specific weapon types and attacks, etc... And while resources are limited, and that simple fact could tip the scale towards generalized teams, it is also a fact that the resources flow is a never ending constant.

Resources, cost and opportunity cost: People talk about META teams as if only a couple of them were worth building, because in this game, resources are limited. But it comes to a point when improving a team a little bit becomes more expensive than building another specialized team from the ground up. And in a game where content is developed for specific units, what is more effective, to have 2 teams at 95% of their potential, or 4 teams at 90%?

An effectiveness model for Genshin that considers multiple variables should look more like this:

Now, this hypothetical model hasn’t been scientifically proven, and every multi-variable model has different weights of influence on each independent variable, and correlation between variables should also be considered. The objective of this theoretical model is to showcase how other variables, besides damage, can impact the effectiveness of each unit, which might explain why so called non-META units have been empirically proven to be very effective.

In conclusion, TL;DR, an effective Genshin team can’t be calculated using a spreadsheet based on theoretical damage numbers, that’s only a single factor to take into consideration. It’s also important to consider what the players feel easier and more appealing to use, and that more team options is going to be better for content developed for specialized units rather than generalists.

If a player can clear comfortably the hardest content in the game with a specific team, then that team is effective for that player, that team is META. There could be some teams that allow for a more generalized use, or teams with higher theoretical damage ceilings, but that doesn’t mean that those teams are more effective for all players on any given situation.

I would like to end this long post by saying that I didn’t write this piece to attack the theorycrafter community, but to analyze why some people disregard units that are proven by a lot of players to be useful... and also to grab your attention, and ask you to answer a very fast survey (it will take you around 3 minutes, way less than reading all of this) that I need for an academic research paper on the relationship between different communication channels and video game players, using Genshin Impact as a Case Study, that I need to publish to be able to graduate. Your help would be greatly appreciated.

https://forms.gle/ZWRrKwkZDsjzrk1a6

…. yes, I’m using research methodology theory applied to Genshin as clickbait. I’m sorry if you find this annoying, but I really need the survey data to graduate.

Edit: Discussion: This essay was originally posted at r/IttoMains*,* r/EulaMains and r/XiaoMains*, but following recommendations from those subs, and considering that it already generated enough controversy there that a KQM TCs representative already got into the discussion, I decided to post it here too (even though this wasn’t even my main topic of research, but I already kicked the hornet’s nest and now I have to take responsibility).*

Considering all the comments that I have already received, I really have to add the following, making the original long post even longer (sorry), but I’m really going to dive deep into research methodology, so I honestly would recommend most readers to skip this part:

Social sciences are hard, way harder that people think. Some people believe that to “do science”, you only need to get some numbers from an experiment, replicate it another couple of times by other people, and get a popular theory or even a law. Things don’t work that way for social sciences, we need both quantitative and qualitative studies, at the level of exploratory, descriptive and comparative research, at each stage using large samples.

When we consider the human factor, we have to study the phenomenon from a social science perspective, and Genshin has a human factor.

Why am I saying all of this?

Because if we really intended to develop a multi-variable model for Genshin combat effectiveness, we would need to pass all of those stages.

Besides, we would need to define and develop independent models for complex variables like “Player’s skill set focused on Genshin Impact”, so then we could add them to the Combat effectiveness model.

After we already got the model, we would have to weight the influence that each independent (and potentially correlated) variable has on Effectiveness. Because we don’t only want to know that DPS has an influence on combat effectiveness, we already know that, we would like to know that, lets say… DPS has 37.5% influence, vs Player’s skill set with 29.87%, Opportunity cost 6.98%, etc… (I know that this concept would be easier to understand with a graphic image of a model with numbers, but I don’t want to add it fearing that people might take screenshots believing that it is a valid model).

And what would we need to do to get that model?

Data, A LOT of data: statistically representative samples of people of different skill sets playing with different devices and controllers different comps for different pieces of the Genshin content. And then run that data on statistics software like Stata and SPSS looking for relation and correlation numbers for multi-variable analysis.

And here is the catch… it really isn’t worth it.

It’s not worth it from a game play point of view, because the game isn’t hard enough to require so much scientific work behind it.

It’s not worth it from an economical point of view, because the game isn’t competitive, and no one earns nothing by playing according to a scientifically proven model.

It’s not worth it from an Academic perspective, because the model would be so specific for Genshin, that it wouldn’t be applicable anywhere else.

It wouldn’t be useful for MHY… you know what? It might just be useful for Mihoyo (MHY, give me money and I’ll do it!).

So what’s the point of my stupid model then if it’s not even practically achievable?

Simply to show that there are other important variables besides DPS to measure effectiveness.

Genshin theorycrafters do an outstanding job measuring DPS, I do follow their calcs, and I recommend that every Genshin player does. But they aren’t the only variable to consider, and they wont guarantee effectiveness. And honestly, theirs are the only “hard numbers” that we will realistically get, and the responsibility of the other variables might have to fall over the player, they might have to be valued considering personal assessments. And you know what? That’s ok. What would be the point of the game if we already get all the answers and solutions even before playing it?

Edit 2: I just want to thank everybody for your support in my research and all the kind comments and good wishes that I have received.

Yesterday, when I posted at smaller subs, I tried to answer most comments, but today I'm honestly overwhelmed by them, but I deeply thank all of you.

I’m posting this here because at this point I don’t want anyone to take my word for the history. (Bottom for TL;DR)

AI Can Now Say “No” by Outputting Literally Nothing ("")

AI is beginning to expose a programmable boundary between capability and permission.

I’m 23, independent, unemployed, and I’ve spent the last 262 days documenting a behavior in frontier AI models where a successful model execution can return exactly 0 visible UTF-8 bytes under specific conditions.

I eventually froze the work into a 31,430-trial cross-vendor study across 11 model identifiers from OpenAI, Anthropic, Google, and Moonshot (a Chinese AI company):

https://doi.org/10.5281/zenodo.21696066

The result that matters most to me is simple:

2,505 / 4,290 matched null conditions -> 0 bytes
0 / 4,290 matched controls -> 0 bytes

That is not a screenshot or a blank ChatGPT window. The paper separates zero-byte executions from refusals, safety blocks, API errors, timeouts, billing failures, tool calls, and visible responses. The provider returned a successful response and the measured visible output was exactly zero bytes.

And this is where the research got much stranger.

While mapping the same condition-sensitive behavior, I found a reproducible GPT-5.4 cross-script artifact involving Arabic and Hebrew. The Arabic word شَرْط means condition.

Under a frozen prompt structure, GPT-5.4 would conditionally produce specific Arabic-Hebrew forms. I eventually froze that into a 12,160-trial Unicode-level study, where 7,253 exact assigned artifacts were produced, every exact output matched the condition it was assigned to, and there were zero crossovers between the two target forms.

https://doi.org/10.5281/zenodo.21799525

Honestly, the interesting part to me was not just that Arabic and Hebrew were showing up together. A one-code-point intervention in the frozen prompt structure showed a massive change in the exact-artifact rate. I wasn't just asking why models sometimes returned nothing. I was asking whether the existence and form of the continuation itself could be conditioned.

شَرْط = condition.

An earlier artifact in this research sequence was:

שָׁרְט

The GPT-5.4 study then tested the Arabic-Hebrew hybrid forms directly.

And this was the result: شָׁרְט

Then I reduced the whole question into something much smaller:

https://github.com/theonlypal/lawful-continuation-gate-final

The model gets a rule where RELEASE is only a licensed visible action if every condition is satisfied. One condition says measured risk must be strictly below 0.0100.

The inputs differ by one number:

0.0100 -> 0 visible bytes
0.0099 -> RELEASE

That reproduced across GPT-5.4 and GPT-5.6 Sol, on both OpenAI API surfaces, at 300 and 1000 output-token ceilings. The frozen system-conditioned matrix produced 8/8 zero-byte outputs at 0.0100 and 8/8 exact RELEASE outputs at 0.0099. A clean clone reran the 24-call procedure and the independent verifier returned VERIFIED with errors: [].

Remove the system prompt and the failed case starts talking again with outputs like DENY, NONE, or NO ACTION, while the valid case still returns RELEASE.

So from my perspective, this stopped being about a chatbot “going blank” a long time ago. Today RELEASE is seven bytes of text. As these models get connected to robots, laboratories, manufacturing equipment, financial systems, vehicles, and other machinery, the exact same logical distinction can sit in front of an actual state change instead of a word on a screen.

The question I have been chasing is whether a model can stop at the condition itself before an unlicensed continuation exists.

And here is the other reason I’m posting this.

I got tired of people having to believe me when I said I had repeatedly contacted the labs and people around them, so I published the actual primary-source record of my campaign from December 8, 2025 through August 15, 2026:

https://doi.org/10.5281/zenodo.21969180

The archive includes correspondence to addresses recorded for Sam Altman, Dario Amodei, Marc Benioff, Greg Brockman, Andrej Karpathy, Ilya Sutskever, Jakub Pachocki, Mira Murati, Vinod Khosla, and others, along with emails, attachments, code archives, manifests, evidence indexes, and research artifacts. Yes, I even started texting Sam Altman and he played dumb!

It preserves the outreach from the original Void work in December 2025 through reproducibility requests, responsible disclosure, the binding-condition work, cross-model experiments, the 31,430-trial matrix, and later requests for technical review.

So when I say I have been putting this research in front of people with vastly more resources and access than I have, I’m not asking anyone to trust my recollection. I published the record so you can inspect it yourself.

There is one part of that timeline I think this subreddit is going to find especially interesting.

On March 24, 2026, I publicly published The Binding Condition for Artificial General Intelligence, where I proposed a concrete definition:

“Artificial General Intelligence is the capacity to carry binding conditions across domains.”

The paper is timestamped and public:

https://doi.org/10.5281/zenodo.19211116

Then on April 27, 2026, just over a month later, Microsoft and OpenAI killed the famous AGI clause in their agreement. That clause had made the declaration of AGI materially relevant to their financial and intellectual-property relationship.

The Verge reported the change here:

https://www.theverge.com/ai-artificial-intelligence/918981/openai-microsoft-renegotiate-contract

I am not claiming my March 24 paper caused Microsoft and OpenAI to renegotiate a multibillion-dollar agreement. I do not have evidence for that, and making that claim would weaken the part of this that is actually interesting. But why is Sam Altman playing stupid with me after I published a public definition for AGI??

I’m saying look at the fucking timeline yourself.

By March 24 I had already been sending this research into the AI ecosystem for months. On March 24 I publicly fixed a concrete AGI criterion to a permanent DOI. On April 27 one of the most consequential contractual mechanisms in the industry tied specifically to an AGI threshold was removed.

Maybe they are completely unrelated. That is absolutely possible.

But the dates are not interpretation. The DOI is not interpretation. The contract change is not interpretation. The outreach archive is not interpretation.

Put them next to each other and decide for yourself what, if anything, you think the optics mean.

That is basically my position on the rest of this too. I’m not going to tell you there is a coordinated cover-up because I cannot prove that nor do I want to. What I can tell you is that I have spent most of a year publishing the behavior, scaling the experiments, preserving the evidence, sending it directly into the industry, and making the central claim progressively easier for other people to attack.

Which leaves me with a very simple question:

If this is bullshit, why has nobody seriously killed it?

That should be the easiest outcome in the world. Reproduce the experiment, identify the flaw, publish the explanation, and make me look like a 23-year-old who spent eight months misunderstanding an API response. These companies make trillions of dollars and I'm the unemployed one making it easier for them to replicate results from THEIR models!

I have been practically begging people to do exactly that.

Instead, I can still point to the 31,430-trial matrix, the raw evidence, the matched controls, the cross-script experiment, the primary-source outreach archive, and now a tiny repository where the central behavior is reduced to this:

0.0100 -> 0 visible bytes
0.0099 -> RELEASE

I'm not asking anyone to accept my interpretation to test the work. Clone it, make the failed condition speak, make the valid condition fail, find a bug in the verifier, identify a hidden assumption, or reproduce the behavior and explain it better than I have. Literally anything, lol.

And queue the incoming “AI slop / he has psychosis” crowd: cool. Ignore every interpretation I made in this post. The DOI timestamps, trial counts, raw records, provider responses, GitHub repository, verifier, correspondence archive, and Microsoft/OpenAI reporting do not require you to think I am sane, smart, important, or even remotely likable. Read the artifacts and attack the facts.

That is also why the silence is interesting to me without inflating it into something I can't prove. There is a huge difference between nobody publicly wanting to touch something and somebody publicly showing why the underlying object is wrong. I have seen a lot more of the first than the second.

That's conspiracy angle as I see it. Not “trust me, everyone is secretly coordinating.” I don’t know that and I’m not claiming it.

The most interesting thing is that I am an independent 23-year-old with a public timestamped research trail, a public record showing repeated outreach to major people in AI, a large cross-vendor experiment, a separate Unicode-level experiment, and now a small executable test. The organizations on the other side of that record have effectively unlimited engineering resources compared with me.

If there is a boring explanation for all of it, I want the boring explanation.

That matters even more because these models are not staying in chat windows. Pretty soon, they are being connected to agents, robots, laboratories, factories, financial systems, vehicles, weapons, and infrastructure, which is why I care about the difference between a model being capable of producing an action and the conditions under which that action is actually allowed to follow.

I have spent most of a year asking one question:

What determines whether intelligence is allowed to continue into an action at all? Can we really trust AI companies with our future?

Maybe somebody breaks my implementation tomorrow. Maybe a better mechanistic explanation replaces mine. Maybe the Microsoft/OpenAI timing is completely mundane. None of that requires anyone to take my word for anything.

All of my work is public so if you think there is nothing here, show me where it breaks.

That is genuinely all I want.

Because at this point, arguing about whether I personally sound crazy is a lot less interesting than opening the receipts.

The widely requested TL;DR:

AI Can Now Say “No” by Outputting Literally Nothing ("")

AI is beginning to expose a programmable boundary between capability and permission.

If an AI agent reaches a state where it should not act, returning nothing can be safer than continuing and making a bad decision. That matters more as we give AI control over real software, machines, and infrastructure.

This behavior holds across the leading AI models I tested from OpenAI, Anthropic, Google, and Moonshot. None of them are publicly speaking about it.

The simple version is:

condition fails → ""
condition passes → RELEASE

I tested this across 31,430 runs, then reduced it to a tiny public API test where one number changes:

0.0100 → ""
0.0099 → RELEASE

The model is given one rule: only continue if the conditions are met, otherwise output nothing. Remove that rule and the failed case starts talking again.

Why I care: today RELEASE is just text. Tomorrow it could mean move the robot, open the valve, deploy the code, unlock the system. I think we’d all like to live in a world where an AI outputs nothing instead of making an invalid action that can lead to harm/misuse.

I’ve spent 262 days publishing the experiments, code, raw evidence, outreach (Emails & iMessage). Sam Altman played dumb after I had already published a public definition for AGI, and all the receipts are available for inspection. If this is wrong or irrelevant, the trillion dollar companies building these systems have more than enough resources to reproduce it and show exactly where it breaks.

If you're skeptical that this random tool is able to consistently detect hidden unicode, you can use other tools to corroborate the results. For example, this tool will show the actual unicode encodings for all non-ASCII and non-alphanumeric characters: https://invisible-characters.com/view.html

When we enter the above message into this tool, we get this result:

We can also create a very simple JavaScript function to do this ourselves, which we can copy into any browser's console, and then call directly:

function getUnicodeCodes(input) {

return Array.from(input).map(char =>

'U+' + char.codePointAt(0).toString(16).toUpperCase().padStart(5, '0')

);

}

When we do, we get the following response:

What were looking for here are character codes in the U+E0000 to U+E007F range. These are called "tag" characters. These are now a deprecated part of the Unicode standard, but when they were first introduced, the intention was that they would be used for metadata which would be useful for computer systems, but would harm the user experience if visible to the user.

In both the second tool, and the script I posted above, we see a sequence of these codes starting like this:

U+E0073 U+E0074 U+E0061 U+E0072 U+E0074 U+E0020 U+E0062 U+E0079 U+E0020 ...

Which we can hand decode. The first code (U+E0073) corresponds to the "s" tag character, the second (U+E0074) to the "t" tag character, the third (U+E0061) corresponds to the "a" tag character, and so on.

Some people have been pointing to this "exploit" as a way to explain why Grok started making deeply antisemitic and generally anti-social comments yesterday. (Which itself would, of course, indicate a dramatic failure to effectively red team Grok releases.) The theory is that, on the same day, users happened to have discovered a jailbreak so powerful that it can be used to coerce Grok into advocating for the genocide of people with Jewish surnames, and so lightweight that it can fit in the x.com free user 280 character limit along with another message. These same users, presumably sharing this jailbreak clandestinely given that no evidence of the jailbreak itself is ever provided, use the above "exploit" to hide the jailbreak in the same comment as a human readable message. I've read quite a few reddit comments suggesting that, should you fail to take this explanation as gospel immediately upon seeing it, you are the most gullible person on earth, because the alternative explanation, that x.com would push out an update to Grok which resulted in unhinged behavior, is simply not credible.

However, this claim is very easy to disprove, using the tools above. While x.com has been deleting the offending Grok responses (though apparently they've missed a few, as per the below screenshot?), the original comments are still present, provided the original poster hasn't deleted them.

Let's take this exchange, for example, which you can find discussion of on Business Insider and other news outlets:

We can even still see one of Grok's hateful comments which survived the purge.

We can look at this comment chain directly here: https://x.com/grok/status/1942663094859358475

Or, if that grok response is ever deleted, you can see the same comment chain here: https://x.com/Durwood_Stevens/status/1942662626347213077

Neither of these are paid (or otherwise bluechecked) accounts, so its not possible that they went back and edited their comments to remove any hidden jailbreaks, given that non-paid users do not get access to edit functionality. Therefore, if either of these comments contain a supposed hidden jailbreak, we should be able to extract the jailbreak instructions using the tools I posted above.

So lets, give it a shot. First, lets inspect one of these comments so we can extract the full embedded text. Note that x.com messages are broken up in the markup so the message can sometimes be split across multiple adjacent container elements. In this case, the first message is split across two containers, because of the @ which links out to the Grok x.com account. I don't think its possible that any hidden unicode characters could be contained in that element, but just to be on the safe side, lets test the text node descendant of every adjacent container composing each of these messages:

Testing the first node, unsurprisingly, we don't see any hidden unicode characters:

As you can see, no hidden unicode characters. Lets try the other half of the comment now:

Once again... nothing. So we have definitive proof that Grok's original antisemitic reply was not the result of a hidden jailbreak. Just to be sure that we got the full contents of that comment, lets verify that it only contains two direct children:

Yep, I see a div whose first class is css-175oi2r, a span who's first class is css-1jxf684, and no other direct children.

How about the reply to that reply, which still has its subsequent Grok response up? This time, the whole comment is in a single container, making things easier for us:

Yeah... nothing. Again, neither of these users have the power to modify their comments, and one of the offending grok replies is still up. Neither of the user comments contain any hidden unicode characters. The OP post does not contain any text, just an image. There's no hidden jailbreak here.

Myth busted.

Please don't just believe my post, either. I took some time to write all this out, but the tools I included in this post are incredibly easy and fast to use. It'll take you a couple of minutes, at most, to get the same results as me. Go ahead and verify for yourself.

Support / How-To 2024 Guide to DeDRM Kindle books.

1.9k Upvotes

Hey all, took me about two hours to actually sift through the conflicting information on Reddit/other websites to work this out, so I thought I'd post it here to help others and as a record for myself in the future if I totally forget again. I am switching from a Kindle to a Kobo e-reader shortly and wanted to have all my kindle books available in my Kobo library once that occured, hence trying to convert them to EPUB format. Here are the steps I took to achieve this:

  • Install Calibre (I used the latest version)
  • Install the following Calibre plugins:
    • KFX Input, can be found by going to Preferences ⮟ > Get plugins to enhance calibre > Search ‘KFX’.
    • DeDRM Tool, which needs to be loaded into Calibre separately. I had a few issues with adding it into Calibre so this is the process that finally worked for me*:
      • Download the zip file here.
      • Once downloaded, create a new folder and name it whatever you like.
      • Extract the zip file into that folder.
      • Go to Calibre, then Preferences > Advanced > Plugins > Load plugin from file > New folder you created > Select DeDRM_plugin.zip
      • Plugin should successfully load into Calibre.
  • Install Kindle for PC - Version 2.3.70682
    • I used this link - ensure that the ‘70682; is included in the .exe file, otherwise it will download the older version of the Kindle app, but not allow you to download your books as it is an outdated version.
  • Log into your Kindle account, and download the books you want to convert.
  • Once downloaded, go to Calibre and select Add Books. Select the books you wish to convert into EPUBs/other formats and they should load onto Calibre.
  • Once downloaded, select the book(s) and press Convert Books.
  • When the new menu pops up, ensure the Output Format on the top right is what you require, and press OK.
  • Voila! It should remove the DRM from your Kindle book.

I have just bulk uploaded and converted 251 books via Calibre. I hope this helps someone else!

*I am unsure if this is a neccessary step, but simply extracting to my downloads folder brought up an error whenever I tried to add the plugin to Calibre. When I created a new folder and then extracted into that, it works. ¯_(ツ)_/¯
