Zero to SGLang: Build Your Own AI Engine

This free course lets you build a working AI server from absolute scratch before you ever touch the real code. It’s a complete roadmap where you hand-code a mini engine, adding features like memory optimization and request handling step by step. This is rare because most tutorials just show you a library without explaining how the inside works. By building it yourself, you actually learn what is happening under the hood, not just how to call a function. It is the perfect way to stop being a black-box user and start understanding the real logic behind modern AI speed.

TScert Proves Your Code Safe

TScert stops you from shipping TypeScript code that crashes at runtime by demanding mathematical proof before it accepts your function. Standard type checkers often miss bugs like reading undefined data, but this independent tool refuses to verify a function unless it can formally prove every step is safe using Lean. It doesn't just check types; it validates a logical certificate to guarantee your code behaves exactly as expected for every valid input. This means if TScert accepts your function, you can trust it won't break under the conditions you defined.

📦 giveen/decomp.anything

Turn Any Binary Into Readable Code

Reverse engineer any software by letting an AI agent write C code that compiles to the exact same bytes as the original program. The tool splits a binary into small pieces, then has the agent guess the source code for each part. It uses the original compiler to build the guess and compares the output byte by byte until they match perfectly. If they do not match, the agent sees the difference and tries again. This works for old games, Windows apps, and Linux tools. It runs entirely on your own computer, so your files never leave your machine. No account needed, no cloud, no privacy trade-offs.
