Updating the Sphinx theme was on my todo for ages and I finally managed to get it done today. I went the popular Furo theme, as I like it's clean looks.

With agentic programming tooling (e.g. #ClaudeCode) #Emacs package maintainers have one less excuse not to adopt Buttercup github.com/jorgenschaef... for their test suites. Claude can convert ERT to Buttercup pretty well in almost no time. (and works surprisingly well with Elisp in general)

How many enterprise companies have meaningfully reduced, or eliminated, their software engineering backlogs. Are we at the point where GenAI is paying off in production?
Are salaries increasing to match this new level of productivity?

Often working on tasks with #ClaudeCode feels like playing a game. That certainly adds a bit of "fun" to programming, which is not a bad thing in my book.

I have to give it to Anthropic, though - their ads making fun of OpenAI were pretty good!

OCaml is already a sweet spot between Go and Rust, but is rapidly gaining the same performance capabilities of Rust without the same cognitive overhead needed for your entire application.
Got my website running live on my zero-allocation (ish) OxCaml webserver! First of a series of posts on building out our planetary computing system infrastructure using the performance extensions in the Jane Street fork of OCaml. https://anil.recoil.org/notes/oxcaml-httpz

What a day for #tennis! I was sure that Sinner was going to fly past Djokovic in straight sets, but Nole just pushed the semi-final to a 5th set! I still think it's super unlikely he'll win, but his spirit and his performance today have been unreal for a player of his age (almost 39). Legend!

Carlos Alcaraz continued to write #tennis history today by winning one of the greatest semi-finals of the AO I've seen. And he did this by overcoming severe cramps that really affected his performance in the 3rd and 4th sets, and trailing by a break in the 5th. A true fighter!!! VAAAAMOOS, Carlos!!!
