From Nand to Tetris: Building a Modern Computer from First Principles

• nand2tetris

  9 0 2.4 Assembly

  An implementation of the nand2tetris project. A full-stack computer: ISA, Assembler, Virtual Machine, Interpreter, Compiler, Operating System, and a Graphical Sudoku game. All from scratch. (by porridgewithraisins)

• src

  745 3,041 10.0 C

  Read-only git conversion of OpenBSD's official CVS src repository. Pull requests not accepted - send diffs to the tech@ mailing list.

Here is the source code of the OpenBSD implementation of cat:

> https://github.com/openbsd/src/blob/master/bin/cat/cat.c

and here of the GNU coreutils implementation:

> https://github.com/coreutils/coreutils/blob/master/src/cat.c

Thus: I don't think building a cat from scratch or creating a tutorial about that topic is particularly hard (even though the HN audience would likely be interested in it). :-)

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• coreutils

  112 4,024 9.3 C

  upstream mirror (by coreutils)

I think you right, and implementing core utils is a nice exercise in system programming.

• nand2minesweeper

  6 2 10.0

  Minesweeper game written in Jack for the nand2tetris course

This was an amazing course and is one of the most rewarding computer science courses I've taken! I loved that there was nothing left to "magic" and it was the first time I felt like I understood the "full stack" of the Java-like code I was writing right down to the silicon atoms.

Self-plug for a full-blown minesweeper game I made for the final project: https://github.com/billmei/nand2minesweeper It's a complete game with a tutorial, custom RNG, and unit tests, using their hardware simulator.
