@davidhewitt.bsky.social@davidhewitt.bsky.social → @davidhewitt.devMy Python 3.15 what's new post is out for the just-released 3.15 beta 1! iscinumpy.dev/post/python-...
Show PostUgh, you're telling me that "great landing" and "good landing" are not `Ord`. In retrospect this makes sense. This plane is clearly a float.
Show PostMy last job was truly the most stressful job I’ve ever had. It was ruining my life. I’m just really, really grateful to be starting 2026 off working with very cool people on a very cool problem, and have time and space for my open source work.
Show PostBluesky custom feeds in Python are now ~x2 faster! ~25-35% faster DAG-CBOR decoding, and ~17% faster CID decoding! I do have more ideas on what to try to speed it up even further! For example, applying BOLT on top of the existing PGO. Huge kudos to @vmx.cx for making this happen!
Show Post🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉
