Ask HN: How do I choose the right resource to learn CS fundamentals?
For Algorithms, I know the amount of materials available online can be overwhelming, so here's an alternative: get a copy of "Algorithms, 4th Edition" [1] from Sedgewick and Wayne, and work through it cover to cover, ignoring any other resources.<p>This book has very little in the way of prerequisites, and it covers a lot of fundamental algorithms and a little bit of Math, but it is a lot more accessible and didactic than, say, the Cormen book. I don't think you need any other resource for studying the book (videos, forums, etc.) other than maybe the website for convenient access to the source code (and maybe some other Java reference, although you don't need deep Java knowledge to understand the code).<p>Note: I'm plenty biased for this resource... I don't know why, but I find the implementations so elegant an easy to follow, even though the source code is Java, a language I admit sometimes can look anything but elegant (in its production form with all those imports and redundant type signatures :-). Many algorithms are implemented using data structures introduced in previous chapters, so it makes sense to read it cover to cover.<p>For Computer Architecture, Nand2Tetris [2] is another resource that comes up often and for good reason. I only worked through half of this book but I really like it too and have it on my back burner to complete the second half of it: first part is about implementing a computer from the ground up (nand gates being the "atoms"); second part is about implementing a parser/compiler for a higher level language targeting the same computer.<p>1: <a href="https://algs4.cs.princeton.edu/" rel="nofollow">https://algs4.cs.princeton.edu/</a><p>2: <a href="https://www.nand2tetris.org/" rel="nofollow">https://www.nand2tetris.org/</a>
