Codeset
Learn anything you want. A full course on the subject, taught one-on-one by an AI tutor and aimed at the work you actually came to do. Every lesson ends in something of your own. Free while it's early.

What it does
Training and evaluating agentic models with large-scale datasets of reproducible, sandboxed environments.
Learn C by writing a shell, or Rust by building a key-value store. Every course comes with a full syllabus, and the tutor teaches all of it inside the thing you're building, one concept at a time. Before lesson one: what do you want to end up with? Anything you'd actually use. Set up pixel-dodger : a game loop, two sprites and an empty scores.py . Same Python syllabus as everyone else — 41 lessons — taught in here. Three screens, in this order, and then you're in lesson one. Search the catalog and read the whole syllabus before you make an account. You get every module and every lesson in the order they come, so nothing behind the sign-in wall is a surprise. The thing you want to end up…from codeset.ai

My Attempt to Organize the World of AI Dev Tools2025 · aicode.danvoronov.com · ▲101I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community. I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me. And I'm personally maintaining this, so your feedback is wellcome.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
