Products that do what Free C course called "C Systems Lab" does

C Systems Lab is a free interactive web course that walks through 10 modules of systems programming in C: compilation, pointers, dynamic memory, structs, the preprocessor, file I/O, processes and signals, sockets, concurrency, and a tour below C. The free course itself is the link. Get the free sample of the PDF by adding "/demo" to the link. Since I don't necessarily like the paywall aspect of it, you may ask me for the complete edition by reaching out via email. Happy to answer questions about the content or the curriculum design.

   Learn C and its lower levels interactively, in the browser▲356

   I made a simple virtual machine that runs C in the browser.This project is made as an experiment to see if C can be learned easier if the lower level is covered in paralel.

   Your Free CS Education▲15

   Cut to the chase: https://www.youtube.com/watch?v=4nyzl3pVXp4 I really am a big supporter of quality education being available for everyone, and because of that I've opted to open source my CS education on YouTube. I'm starting with Rails, and I will eventually work around to more core CS topics like circuits -> logic gates -> binary -> assembly -> c -> Data Structures -> Algorithms etc. If you like it subscribe and I'm looking for all the feedback I can get on how to make it better :)

    Self Hosting C Compiler▲5

    This is my hobby C compiler project. Decided to publish the code today, as it finally compiled itself. The readme on the linked GitHub page has a bit of information on how it works. I wrote the thing for fun, but if anyone gets a better understanding of the dark corners of C because of it, I am happy.
