Hey HN! Made this as a student, and finally got around to open sourcing it. I've used it a lot, even after finishing the course for which I wrote it.

Please open an issue if you see anything incorrect!

I took, struggled with, and loved 213 at CMU when I took it. This is incredibly well done, thanks for sharing!

Thanks for the kind words!

I learned more from the labs in that class than from many other classes combined. It was undoubtedly some of the hardest work I did during undergrad, but also some of the most fun and rewarding.

For me, 213 was the class after which I truly felt like a real programmer. By the end, so many layers of abstraction had been peeled back that it felt like there was no error or bug that I couldn't get to the bottom of if I dug deep enough.
