Practise the exact skills the projects need

26 short exercises in C and Python. You write code, press Run, and see what it does — in this page, with nothing to install and nobody to sign up to. Each one prepares you for a specific project in one of the tracks, and you can stop after one.

The code runs in teaching runtimes built for this site — a 32-bit model machine for C, and a Python subset. They stop on the mistakes a real toolchain lets through and explain them in words: reading memory you never wrote to, running off the end of an array, citing a policy that was superseded a month before the claim. They are not the compiler or the interpreter your project will use, and they do not pretend to be.

Build the real thing

Exercises are rehearsal. The project is the work: a brief, a repository you build in, commits reviewed as you go, and something you can show someone afterwards. Signing in with GitHub is what sets it up.
