What a shit take. The article itself is perhaps a nice light overview of 101-ish level concepts, although knowing how and when to apply them in a real engineering context is not something I would consider 101 level. And certainly, building something that is actually at the scale of GitHub Search is nowhere near 101 level. This is what a 101-level inverted index implementation looks like: https://github.com/BurntSushi/imdb-rename https://github.com/BurntSushi/imdb-rename In other words, absolutely nothing like what GitHub built. Nowhere close.
