TIL: git (the command line tool) now contains LLM generated code (I'm still unsure, we're calling this generative AI, right?). Landed in Jan 2026.

My guess is that people who work on small codebases with low-turnover teams (say, Redis or games like The Witness) would say “obviously you have to understand it completely, otherwise you can’t do good work”. I’d also guess that people who work on large codebases with high-turnover teams (say, the Google web search backend or GitHub) would say “obviously you can’t understand it completely, you just have to do the best you can in your local area”.

These are two largely different ways of programming with different methods, practices and cultures. However, the first group is over-represented in online discussion about software engineering. I want to defend the second group against the first.

ColorSym is a free, open-source color-identification system that pairs every color with a unique, memorable symbol. When color alone isn't enough to tell things apart, the symbol does the job, so the roughly 1 in 12 men and 1 in 200 women with color vision deficiency can read your components, charts, or UI with confidence.
