FOSK (Free and Open Source Knowledge) is a collection of tech-related books and webpages that are free to read. This project was born out of my necessity to find good study material for my self-taught journey. I hope this helps you on yours.

Topics are listed in alphabetical order. Topics' content is listed in the order which they were added.

• Algorithms Design (in C)

• Beej's Guide to C Programming
• Beej's Guide to C Programming (Library Reference)
• Beej's Guide to Network Programming
• Modern C

• Brave Clojure

• Dive Into Systems

• Beej's Guide to Networking Concepts

• Open Data Structures (in C++)
• Open Data Structures (in Java)
