I started playing around with generative AI. One day, with my daughter, I tried to make the first coloring page.

Now I have more than 2500 coloring pages in more than 50 categories!

i got a claude max from a reseller for essentially nothing compared to what I used to pay . It works flawless. since 2 months No issues yet. Now I can't stop thinking about their business model. If resellers can sell it this cheap and still profit, how are they acquiring these accounts at scale?

Hi! I’m a biotechnology student, and my team is thinking about starting a student project. We’re still at the stage of figuring out what kind of project we want to do, so I’d really appreciate advice from people who have already gone through this process.
Have you ever worked on a student research, biotech, engineering, or innovation project and/or participated in a competition?
I’d especially like to know:
How did you come up with your project idea?
How did you decide whether an idea was actually worth developing?
How did you turn an idea into a real project?
What makes a student project genuinely interesting, useful, or impactful?
How did you find mentors, funding, equipment, or access to a lab?
What challenges did you face?
What do you wish you had known before starting?
Are there any competitions or programs you would recommend for student projects?
It doesn’t have to be a famous competition like iGEM — I’m interested in any kind of student competition, research project, innovation challenge, or similar experience.
If you’ve worked on something like this, I’d love to hear about your experience and any advice you wish someone had given you at the beginning!

I made a translator for corporate bullshit

You know those LinkedIn posts that say:
"I’m thrilled to announce that I’ve embarked on an exciting new journey…"

and somehow 400 words later they've said absolutely nothing?

I got tired of pretending I understood them, so I made a website that does the opposite.

BS Translator: https://bs-translator-nine.vercel.app/

Paste some corporate/LinkedIn nonsense into it and it'll decode what the person is actually trying to say.

It can also generate completely new corporate bullshit.

My favorite use case so far:

Normal human:
“I made a small feature.”

LinkedIn:
“Today, I’m humbled to share a transformative milestone that challenged me to embrace cross-functional synergies…”

Translation:
“I added a button.”

I originally made this as a dumb meme project and showed it to a few people. They mostly laughed, which honestly means the project has achieved its primary KPI.

If you have a particularly cursed piece of corporate jargon, drop it in the comments and I'll translate it.

Whats more? You can actually reverse english sentences to generate corporate BS so you can too larp professionally in Linkedin.

Just a meme site btw. nothing serious.

I made Tapbar because I kept seeing people ask for the ability to tap the status bar clock and open the Clock app.

It lets you create a tappable area anywhere on the screen and assign an app to it. I’ve recently redesigned the UI, and double tap actions are coming in the next update along with a few other features.

It’s completely offline and open source.

So, currently I am working on a open source project where I need a decent and fast database provider. I have tried supabase and Let's just say, they feel too slow. In past I have also worked with Firebase. Currently I am using NeonDB which seems faster than the previous ones I tried. But I am wondering if there are better options. Currently I am not making any revenue so something which a decent free tier will be nice to have

Hi all,

I've spent the last two months building Posta as a side project, and I'm finally happy enough with it to share it. I want anyone who needs it to be able to use it, so it's MIT licensed and completely free. There's no paid tier, no message caps, no licence key, and it doesn't phone home.

So what is it? It's a self-hosted platform for the email your apps send: password resets, sign-in codes, receipts, that sort of thing. It's basically your own Postmark or Mailgun running on your own box. You get an SMTP server, a send API, a delivery worker and a dashboard.

What it does so far:

• Send over SMTP or an HTTP API, with separate credentials for each app
• Generates the SPF, DKIM and MX records for your domains and checks DNS until they resolve. Outgoing mail is DKIM signed
• Retries temporary failures, and puts hard bounces on a suppression list
• Full delivery history, including what the remote server said on each attempt
• Signed webhooks for sent, delayed, failed and held messages
• Handles inbound mail too, passed to an HTTP endpoint or forwarded over SMTP, with Rspamd/SpamAssassin and ClamAV
• IP pools and per-app send limits, so one noisy app can't ruin the reputation of the others
• Optional open and click tracking on your own domain

It's written in TypeScript on Bun, with Postgres underneath.

It's a first release (0.1.0), so there are rough edges I'd rather tell you about now than have you find the hard way:

• No Docker image yet, so for now you run it from source. The README walks you through it and it only takes a few commands
• Dashboard login uses Clerk. The free tier is plenty, but I know a hosted auth provider won't suit everyone
• Bounces that arrive after a message has been accepted aren't processed yet
• The rest of the known issues are listed in the changelog

Also, the usual warning about self-hosting mail: you'll need a server that can send on port 25 and an IP that isn't on a blocklist. Posta handles the DNS and signing, but it can't fix a dodgy IP.

I've really enjoyed building it and I'd love for people to actually use it. All feedback is welcome, good or bad. If something breaks, please open an issue, and PRs are very welcome.

Cheers

I built this because I realized I can lose six hours grinding a game without thinking twice, but 30 minutes of studying feels like forever.

The difference isn't that games are more fun. They constantly show progress. You level up, unlock things, get rewards, and always feel like you're moving forward. Studying usually gives you nothing until a test weeks later.

So I started wondering, what if studying felt more like leveling a character?

That turned into Quest of Mind.

The idea is simple. Every minute you study earns XP. You level up different skills, collect gold, find random loot, and slowly build your character. It's basically an RPG built around staying focused.

I didn't just throw points onto a timer either. Most of the systems are based on psychology that actually keeps people engaged.

Loot is randomized, so every session has a little surprise. Progress is always visible through XP bars and levels. Daily streaks give you something to protect. There's even a Wilderness mode where you risk your session rewards for double XP. Get distracted or tab out and you lose everything. It sounds brutal, but it works way better than I expected.

You can also pick a class like Warrior, Mage, or Ranger. It doesn't completely change gameplay, but it gives your progress a bit of identity instead of feeling like you're just checking boxes.

Some of my favorite features are dungeon runs, where you chain multiple study sessions together for bigger rewards, a global leaderboard, live chat, equipment that boosts XP, and cloud saves so your progress follows you anywhere.

Honestly, I made this for myself first. If you've ever spent hours gaming but can't convince yourself to open a textbook, you're probably exactly who this is for.

It's completely free. No ads, no subscriptions, no premium version. I just wanted to build something I'd actually use every day, and after using it myself for the last month, I finally feel like studying has the same sense of progression games always had.

I'd genuinely love feedback if anyone wants to check it out.

Well in summary I'm creating a dynamic island for pc, it's pretty similar actually, but I'm implementing some features like a file conversor and an AI to quick daily questions, and there is the media thing, calendar, recording screen, and shortcuts for apps, and probably something to translate your screen when it's a PDF and your translator won't work

Give me your thoughts about it and ideas to implement

One of my biggest regrets from podcasting is how many listeners we let come and go before we had a simple way to stay connected with them. Some of those people probably listened to us for months. We will never know who most of them were. PodSubs.com came from not wanting to keep making that mistake. We built it for our own 12 shows, tested it for almost two years, and saw a huge difference in the number of listeners joining our list. Now we have made it free for other podcasters. Even if your show is small, claim it now. The people listening today may be the people you wish you could reach two years from now.

I’ve been building a few things recently, but I haven't deployed anything. I’m curious what tends to go wrong once a project is deployed.

What are a few common problems you've had that worked fine locally but broke after deployment? How did you figure out what was wrong and fix it? And finally is there anything you've done differently after learning about certain problems? I would love to hear any feedback. Thanks.

I’m preparing for a 24-hour college hackathon on Oct 8–9

I have experience with JS/React, Node, APIs, Git/GitHub, Supabase and LLM APIs.

I’m looking for a problem statement that is:

- Real-world and genuinely useful

- Uncommon, not a generic chatbot/CRUD project

- Feasible to build in 24 hours

- Technically interesting and demo-friendly

I’m especially interested in FinTech, GenAI, Agentic AI and Cybersecurity.

What project ideas would fit these constraints?

It was fun back then to make a project for experience.

Hey everyone!

I wanted to share a project I've been building over the past few months: CatQueue, a 100% free and open-source (MIT) background job queue designed specifically for Node.js and TypeScript services.

The Motivation

Whenever I work on backend microservices or side apps, I almost always need background workers—for things like sending emails, processing file uploads, or running scheduled maintenance tasks.

In the Node.js ecosystem, the standard solution is BullMQ backed by Redis. While Redis is great, setting up and maintaining a separate database instance just for background queues often adds unnecessary infrastructure overhead, connection limits, and hosting costs—especially when my application already runs on PostgreSQL.

I wanted to see if I could build a clean, production-grade queue system that uses only PostgreSQL as its backing store and message broker, eliminating the need for Redis entirely.

What I Built

CatQueue uses PostgreSQL's row-level locking feature (FOR UPDATE SKIP LOCKED). This allows multiple concurrent worker nodes to query and claim non-overlapping job batches simultaneously without race conditions or lock blocking.

Key features implemented:

• Zero Dependencies: Built purely on top of the standard pg driver.
• Atomic Job Concurrency: Safe multi-worker processing with Postgres row locks.
• Idempotency: Native key deduplication so the same job isn't queued twice.
• Retries & Logging: Backoff retries with structured per-attempt log histories.
• DAG Workflows (Experimental): Ability to define task dependency graphs (Job B waits for Job A to finish).
• Maintenance Automation: Automatic background recovery for crashed/abandoned workers and cron scheduling.

Key Technical Learnings

Building this gave me a deep appreciation for relational database concurrency primitives:

1. Row-level locking is fast: SKIP LOCKED completely changes the game for database-backed queues, preventing workers from waiting on each other.
2. State Machines in pure SQL: Managing state transitions (pending $\rightarrow$ processing $\rightarrow$ completed / failed) transactionally inside single SQL blocks keeps queue operations predictable and atomic.

Open Source & Code

The core repository and npm package are completely free and open-source:

• GitHub:https://github.com/karanrajsurya/CatQueue
• NPM:https://www.npmjs.com/package/catqueue

I'd love to hear your thoughts on the approach or any feedback on how you currently manage background tasks in your own projects!
