There's hardly any greater satisfaction in life than being able to do a binary identical round-trip of ISO-8211 encoded file -> XML -> ISO-8211 including fields whose data struct code is concatenated

Sad reality of open source in 2026: when a new contributor asks if they can contribute and their github profile looks fancy, actively discourage them to avoid loosing your time afterwards

I love when a NVIDIA employee protests against chardet full AI-driven rewrite causing "unacceptable legal risks" to chardet's users. Aren't they the ones that sell that hardware that make the whole thing possible: https://github.com/chardet/chardet/issues/331 ? A bit like a rifle maker protesting against mass shooting...

I just realized that one of the recent PROJ contributor was actually using LLM. Is it rational that I feel disappointed that it is not his code but coming from a bot (I was so amazed to see someone else than me hacking into the CRS-to-CRS pipeline generator). Maybe it is not rationale, but who said that humans act rationally ? (speaking about rationality, just discovered yesterday https://en.wikipedia.org/wiki/Newcomb%27s_problem which is quite funny)

I'm officially an old timer. I'd say more than half of contributions to GDAL and PROJ those past weeks have been largely LLM driven.
