thoughts on teachyourselfcs.com
I think any programmer who sees their craft as something more than just simply a paycheck should have a solid foundation of cs. Here are some reasons if you need. Out of all the free resources out there, I belive teachyourselfcs.com to be the best one. Feel free to read more on the website's FAQ on how it compares to Open Source Society or freeCodeCamp curricula.
Although there are some great ones, I believe there could be some modifications, as well as project-based learning ideas. Here they are.
Algorithms and Data Structures
Algorithm Design Manual is a great read. In addition, I highly suggest checking out all the references listed out on one of my personal open source projects. I should probably link them here, but I'm too lazy. But seriously, go check them out. They are amazing resources.Project
Hands down, implement all data structures. Simply studying their APIs,
in my opinion, doesn't give you true intution. Feel free to checkout my
iruka if you need any
Also, leetcode. Always, leetcode.
The guide recommends Operating Systems: Three Easy Pieces (OSTEP). I also suggest reading the dinosaur book, Operating System Concepts tenth edition. The guide links to the ninth edition and says the book has attracted criticism for lack of clarity and general student unfriendliness. I disagree with the criticism, at least for the tenth edition. It was very useful in filling practical gaps that I didn't get from the theory-heavy OSTEP.Project
I also suggest you build a toy kernel to really have an understanding for what a kernel is. Simply another piece of software with no stdlib that manages messy hardware stuff for applications. I followed this amazing guide in Rust written by Phillip Oppermann. If Rust is not your thing, try to find a similar guide that walks you through it like Phillip does. Can't recommend this resource enough. The guide is in progress though and currently stops after cooperative multitasking implemented with async await. It's missing preemptive multitasking implemented with threads, and the fs abstraction. I didn't care enough to finish my kernel, as I already learnt what I was looking to learn.
The textbook the guide recommends is great. Computer Networking, A Top-Down Approach. I also suggest watching the University of Washinton's Networking lectures.. David Wetherall does a great job explaining networks bottom up. Also check out Beej's Guide (Handbook) To Network Programming.Project
For your project, go through The UChicago X-Projects. Create toy implementations of IP, TCP, and the IRC protocols. Stanford's CS 144 Labs are also great. You implement the entire network stack from the ground up.
The primary resource suggested, Berkely's CS 186 is great. In addition, check out Use the index, Luke! for a great guide on database indexes. As application programmers, I think the most important takeaway from a databases course is indexes, and not hardcore database implementation.Project (Haven't done)
For the project, I suggest doing the chidb project from The UChicago-X projects. You'll be implementing a SQLite clone!
Nothing much to say here. Designing Data Intensive Applications is a great read. You can find great summary notes on timilearning.Project
Follow the guide's course sugestion, which is MIT's 6.824. It's a lab-based course, in which you'll implement map reduce, raft, KV raft, and a sharded KV store. Just make sure to use the 2020 offering. The GOAT and legend himself, Robbert Morris (Morris worm), is the lecturer. Also definitely read all the papers, and try to find a few friends to create a dicussion group. timilearning also has great summary notes on the course too.
Language and Compilers
In addition to Crafting Interpreters is a great book that runs through a tree-walk interpreter and a bytecode-VM-based compiler. Also, if you need motivation on why you should about compilers, check out Steve Yegge's classic Rich Programmer Food.
The guide has no mention of any Programming Language (PL) theory resources, which arguably is more important than knowing how to write an interpreter/compiler. Some resources that people seem to recommend are Essentials of Programming Languages, Theory of Computation and Dan Grossman's PL course on coursera.Project
Implement a toy compiler with two languages you want to learn better! For example, I love Rust and Typescript, and so plan on writing a Typescript compiler in Rust.
