Bits and Pieces: zlib compliant DEFLATE from scratch

zlib underlies most zip file decompressors, and DEFLATE is one the binary formats used to store compressed data in a bitstream. The goal of this article is to walk through how my Python DEFLATE compressor implementation works. There are many guides on the internet that describe how to implement each step of DEFLATE, but very few end up producing a bitstream that can actually be parsed by a library like zlib. This article assumes that you roughly know how each step of the DEFLATE algorithm is implemented, but are having trouble with some of the finer points that are often glossed over.

The code can be found in "deflate.py".

CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d
