# Distributed Systems
- The Systems Design Primer (opens new window) is a great big repo full of goodness that covers everything from "what is a load balancer?" to "what kind of database should I use?" It links to lots of real-world examples (mostly on company blogs) and also provides a set of Anki flashcards (in case you're studying for an exam 😅).
# Operating Systems
- Operating Systems: Three Easy Pieces (opens new window) is a free online textbook that introduces basic operating system concepts like processes, virtual memory, and file systems in an accessible, highly-readable way.
# Programming Languages
- Crafting Interpreters (opens new window) is a (sadly unfinished) book-length tutorial on building your own interpreter, from the ground up (including every single line of code!). The Durian (opens new window) team made a lot of use of it!
# Machine Learning
- Neural Networks and Machine Learning (opens new window) is an overview of (deep) neural networks, one of the most popular techniques for machine learning. It's written by Michael Nielsen, also known for one of the standard quantum computing textbooks.
