I absolutely love the "What's In A GIF" series. It's what inspired me to write my own GIF decoder while learning Erlang at the same time: https://github.com/avik-das/giferly https://github.com/avik-das/giferly The first time around, I struggled a lot with decoding errors. Many years later, after being a more experienced developer, I wrote the LZW decompression with unit tests. Doing so forced me to think about each edge case, and fix issues without breaking existing functionality. Very quickly, I was able to open pretty much any GIF file I threw at it!
