Less than a week until ‹Programming› 2026 in Munich (March 16–20)!
What’s ahead:
- 4 days of deep-dive sessions.
- Workshops including MoreVMs, PX/26, SCLIT, VIMPL, and Substrates.
- Networking in the heart of Bavaria.
We can’t wait to see you there!

20 years ago we got "git means you can work offline". now you have to be online all the time to use your LLM and meanwhile github can't stay up for 24 hours at a time
Just need to create a random UUID for each project. The typical UUID rendering will probably be too “wordy” though. A Zalgo- and ULID-inspired encoding would probably be best. Maybe with git- and jj-style “trim to locally unique prefix”? Pronunciation decisions left to the reader.

The deadline of the ICOOOLPS workshop is soon!
Want to talk about language implementation challenges, experiences, and/or research?
It will be in sunny Brussels end of June!

That sounds like a “yes”! 😀
Sharing a 5-part series on content-defined chunking (CDC) algorithms as background research for my master's thesis on source code deduplication. It's a tour of the algorithms, a deep dive into FastCDC, and explores costs for building deduplication pipelines at scale.

I went a little overboard with this and a little bit insane. moultano.wordpress.com/2026/02/22/t...
Very few people know that the Go standard library has an internal DSL used to make sure that no new intra-stdlib dependencies are added when a change happens:

over a year ago, i gave a talk at the xoxo conference about a mural, a mcdonald’s, and a man. (but it was also secretly about life, and legacy, and meaning.)
finally, i’m blogging the full story, with behind-the-scenes details, and a video of the talk.
enjoy. cabel.com/wes-cook-and...
This weekend I was thinking about programming languages. Programming languages for agents. Will we see them? I believe people will (and should!) try to build some. lucumr.pocoo.org/2026/2/9/a-l...
Programming Language Implementation: In Theory, We Understand. In Practice, We Wish We Would.
In about a month, on March 9th, I'll give my inaugural lecture.
I'll probably complain about the complexity of modern programming language implementations...

#POPL is coming up fast... I'll be there if anyone wants to catch up or talk about the latest in Python typing (and type checkers)!
happy chase-lev patent expiry day to all those who celebrate!!!!!!!!! please enjoy a straightforward implementation in C https://github.com/wingo/whippet/blob/main/src/shared-worklist.h
I can't quite believe that we're now announcing the eighth Programming Language Implementation Summer School (PLISS), but we are --- in May next year, if you want to learn more about programming language implementations, this is the place to come!
finally found a non-empty crate that doesn't change the layout of non-empty collections this is so peam
so pumped for the ty beta to finally be here, we did so much great work it rules! astral.sh/blog/ty

Finally tried uv. It’s not just fast: it’s laughably fast.
Like, “this is what should run every kind of package management on a whole computer” kind of fast.
** Speaker announcement ** Our next speaker is Andrew "BurntSushi" Gallant!
Andrew is a member of the Rust project and maintains many important crates.
Info & tickets: 2026.rustweek.org
