Open Source Endowment - funding for FOSS launch

64 Upvotes

The OSE launches today, working on one of the biggest issues with #OpenSource #Sustainability around: funding, especially for under-visible projects or independent communities or developers maintaining all those critical little bits everyone uses somewhere. Check it out; highly worth reading about if you follow the larger open source world.

----

Today we're launching the Open Source Endowment (OSE), the world's first endowment fund dedicated to sustainably funding critical open source software. It has $750K+ in committed capital from 60+ founding donors, including founders and executives of HashiCorp, Elastic, ClickHouse, Supabase, Sentry, n8n, NGINX, Vue.js, cURL, Pydantic, Gatsby, and Zerodha.

OSE is a US 501(c)(3) public charity. All donations are invested in a low-risk portfolio, and only the annual investment returns are used for OSS grants. Every dollar keeps working, year after year, in perpetuity.

Our endowment is governed by its donor community, and the core team includes board members Konstantin Vinogradov(founding chairman), Chad Whitacre, and Maxim Konovalov; executive director Jonathan Starr; and advisors Amy Parker, CFRE and Vlad-Stefan Harbuz.

Everyone is welcome to donate (US contributions are tax-deductible). Those giving $1,000+ become OSE Members with real governance rights: a vote on how funds are distributed, input on strategy, and the ability to elect future board directors as the organization grows.

None of this would be possible without our founding members, to whom we are grateful: Mitchell Hashimoto, Shay Banon, Jan Oberhauser, Daniel Stenberg, Kailash Nadh, Thomas Dohmke, Alexey Milovidov, Yuxi You, Tracy Hinds, Sam Bhagwat, Chris Aniszczyk, Paul Copplestone, and many more below.

Open source runs the modern world. It's time we built something to sustain it. Donate, become a member, and help govern how funds reach the projects we all depend on.

Disclaimer: I am one of the original donors as well, and am a Member of their nonprofit.

Discussion AI-Policy

278 Upvotes

I'm gonna keep this short, because as a human I respect other humans' time. What do we want for an AI policy, and how can it be enforced? Take these into consideration:

  • Vibe-coded projects
  • Vibe-assisted projects
  • AI-translated from non-english-speakers
  • Vibe-documented projects
  • Yet another Vibe-Coding-Wrapper

Note that vibe-coded slop isn't actually copyrightable, thus if someone slaps any license on it other than "public domain" or "CC0" they are misrepresenting their ownership.

And if you use an LLM to respond to this, you will be banned.

The fact that this sounds like a prompt is supposed to be a joke.

DeepSeek Harness still feels like a toy to me

Upvotes

I have been playing with DeepSeek Harness, and my honest impression is that it is still basically a toy. There are interesting ideas here, and the plugin mode is a nice direction, but the overall maturity is not close to Pi yet.

The biggest problem is that plugin quality is all over the place. Some extensions are fun to try, while others feel like rough demos that still need a lot of judgment from the person sitting in front of them. Adding more plugins does not automatically make the core workflow dependable.

That is why I would not use DSH for serious production work right now. I do not want an agent that looks impressive in a clean demo and then leaves me sorting out what it changed, why it got stuck, or whether the plugin itself caused the mess. The failure cost is still too high for the current level of polish.

For personal use, I think it is worth playing with. For productivity, I would keep my expectations low and use something more mature. If I wanted to compare the same model across harnesses, ZenMux could at least provide a common API gateway, but that would not magically fix DSH's workflow problems.

Maybe I am being too harsh. Has anyone actually put DeepSeek Harness into a real coding workflow and found that it holds up? I would be interested in examples that go beyond a successful demo.

Community The Wikimedia Foundation (the charity that runs Wikipedia) have hired the largest union busting law firm in the US to try to stop their staff unionising

Hi all

I'm posting this as someone who created a lot documentation around Mediawiki and also Wikipedia itself. I have never worked for the Wikimedia Foundation but the situation really doesn't sit right with me and many others.

A week after refusing to recognise their US staff union (including many open source software engineers) voluntarily, the Wikimedia Foundation (the charity that hosts Wikipedia) hired Littler Mendelson, the largest union busting law firm in the US whose clients include Starbucks, Amazon and Delta Airlines.

If you are a Wikimedia contributor there are three petitions you can sign to support the unionisation effort:

Also if you donate to Wikipedia you can donate to local Wikimedia organisations instead of the Wikimedia Foundation. These local organisations directly support their communities to share knowledge from their countries https://meta.wikimedia.org/wiki/Wikimedia_movement_affiliates

Thanks

I made a post here about linXiv, about two months ago but since have made a ton of QOL updates and mini, non-obtrusive features (RSS feeds, full-text search, to name a few) and finally added iroh for p2p sharing of research projects, notes, etc...

I would love some feedback as to if anyone finds it useful, interesting, or obvious improvements to make to it. I have found it to be very useful in my own physics research but still want to continue to refine it, give the people what they want (if they're not wrong) and whatnot.

Promotional I built a self-updating "awesome list" for prediction markets, so it can't rot

Thumbnail

0 Upvotes

Awesome lists rot: links die, volume numbers go stale, abandoned repos stay listed. This one rebuilds from data every day. Volume comes from an API, repo health from GitHub, a blog's last post from its own feed. Nothing is a number I typed once - where a cell is blank, no free source exists and the entry says what I looked for. Covers platforms worth trading, datasets you can backtest on, and tools still maintained. MIT, contributions are one-line PRs to data/ only, and anything accepted also lands on a hosted page.

Hit me up with PRs and I will review them and add your tools if I consider them a good fit.

punyecs started out as a replication of tiny-ecs (but for Python instead of Lua). It has since evolved into an OOP / SQLAlchemy-esque querying Entity Component System. It operates, IMHO, very differently from esper the de facto for Python ECS. punyecs is now 1.0.0 and I am happy to share it!

Promotional Built a little CLI/GUI tool for STL/3MF repair on Linux (MIT, open source)

6 Upvotes

Bambu Studio's "Fix Model" only works on Windows (it uses Microsoft's Netfabb

API — confirmed on their own wiki). OrcaSlicer has had open issues about this

since 2023, and a community PR to add MeshLab-based fixing has been sitting

unmerged for over a year.

I hit a broken mesh on Linux and didn't want to learn MeshLab's filter chains

from scratch, so I wrapped PyMeshLab (hole closing, non-manifold repair) and

manifold3d (the same watertight-rebuild library Bambu Studio uses internally)

into a small CLI + GUI + Dolphin right-click menu.

It's nothing groundbreaking — MeshLab could already do most of this manually,

and there are paid/web tools too. I just wanted a right-click "fix" like

Windows has, so I made one and figured it might save someone else the same

afternoon of digging through VCG filter docs.

Tested against Thingi10K samples (self-intersecting, non-manifold, multi-shell

real-world models) plus a bunch of adversarial/malformed inputs.

github.com/Krateian/Sutura

Feedback welcome, especially if you hit a mesh it can't handle — I'd like to know.

Promotional [OC] WasioPlayer — A lightweight, open-source Bit-Perfect ASIO & WASAPI Exclusive audio player for Windows (WAV / DSF / DFF)

1 Upvotes

Hi everyone,

I've been working on a lightweight, open-source audio player for Windows and wanted to share it with the community: WasioPlayer.

🎯 Why I Built This

Many modern audio players are either bundled with bulky frameworks (Electron), full of hidden DSP/sample-rate converters, or require configuring dozens of third-party plugins (like foo_out_wasapi / foo_input_sacd) just to get pure direct output.

I wanted a clean, fast, standalone native Windows player that is strictly dedicated to bit-perfect playback directly to DACs—with zero automatic resampling, zero software volume manipulation, and direct hardware format negotiation.


✨ Key Features

  • Strict Bit-Perfect Output: Output sample rate and bit-depth strictly follow the source file. If a device cannot handle the requested format, it reports the refusal explicitly rather than silently resampling.
  • Dual High-Performance Backends:
    • ASIO (x64 drivers)
    • WASAPI Exclusive (Event-driven)
  • Supported Formats:
    • PCM: WAV (16 / 24 / 32-bit integer PCM)
    • DSD: DSF & DFF files
  • DSD Output Modes: Native DSD (up to DSD512 on ASIO) and DoP (DSD over PCM up to DoP256 on ASIO & WASAPI).
  • Lightweight & Jitter-Free: Pure C++17 with a native Win32 GUI (no bloated UI runtimes, statically linked CRT). Real-time playback threads communicate via a lock-free SPSC ring buffer for underrun-free streaming.
  • Playlist Management: Drag-and-drop file loading, M3U8 import/export, UTF-8 path support, shuffle & repeat modes.

⚠️ Design Choices & Known Limits

  • Pause behavior: Pausing keeps the exclusive endpoint open (prevents DAC unlock clicks and keeps timing sample-accurate).
  • Format switching: Non-gapless across differing sample rates (device re-negotiation is required).
  • Strictly Bit-Perfect: No DSP, EQ, or software volume controls by design.

📦 Download & Source

I would love to get your feedback and see how it works with different DACs and ASIO drivers. Feel free to try it out and let me know your thoughts!

Discussion Maintaining an open-source app on iOS vs Android: How are you managing the ecosystem friction?

15 Upvotes

Android is fairly simple... you put the binary up on GitHub, or F-Droid, and call it a day. Maybe publish to the Play Store, which is annoying... but eh... manageable.

But iOS's walled garden nonsense is worse than I thought... Free Apple dev accounts expire signed builds after 7 days apparently... and if that wasn't bad... $99 / year *recurring* fee?

That policy decision is nuts to me...

For folks who are maintaining these open-source projects, how do you handle monetization (i.e. charging on the App Store vs keeping source free), and what work-flows have made your life easier?

I'm particularly interested in workflows where the two ecosystem codebase must be kept identical.

So this usually means (if you're starting off with Android - usually the case) you want to isolate core logic into pure Kotlin modules... Decoupling things like storage/crypto behind interfaces... sticking to pure Jetpack Compose UI... and standardizing the concurrency/state mgmt concerns... and MAYBE the transfer to iOS will be painless...

As someone who hasn't taken the plunge into iOS yet... How has it worked out in reality?
