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.
