Open source security at Astral Insights and guidance from our engineering team on how Astral secures its tools.

the last two weeks have been ~exciting~ in terms of open source security! I've put together a post on Astral's blog about how we think about open source security:

Arch Linux (Arm) Update for MNT Reform All required packages to run Arch Linux Arm (ALARM) are now available on the Arch User Repository: Linux & Linux Headers Reform Tools Reform LPC Module i.MX 8M Plus Wifi Module & Firmware Reform tools & modules build from source. Linux & headers are bin-only for now. You can view the whole kernel and headers build process used for these packages. You can also pick up an SD Card image there if you want to try it out. If you like what’s happening here please feel free to vote for these AUR p...

Don’t worry it’s just the Childrens Hospital crossover event

I have written a blog post about how my blog (and most of the rest of my online presence) is all stuck in a small box that lives under a TV: codon.org.uk/~mjg59/blog/...

from earlier this week: "uses for nested promises", where I look at why you might ever *not* want implicit promise flattening, and how promises concatenate things in time the way arrays do so in space blog.jcoglan.com/2026/03/23/u...

Making your conference talk slides? Make the font bigger. Do it again. I know the default font looks ok when you’re looking at it on your laptop but I promise no one can read that from the back

If you can’t fit all the words you want on one slide, you have too many words. Make another slide!

if your specific niche is also "bizarre intertwingled anecdotes about 1950s-1990s computer scientists" i have built your holy grail:

just took a thousand oral histories from the @computerhistory.bsky.social museum and made them fully searchable and deeply interconnected

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”! 😀

From Problem to Taxonomy An introduction to content-defined chunking: why fixed-size splitting fails, how content-aware boundaries solve the deduplication problem, and a taxonomy of three CDC algorithm families.

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.

Wes Cook and the Centralia McDonald's Mural A personal story about discovering a mural in a McDonald's, an unknown artist named Wes Cook, saving the mural, and a conference talk about the whole thing.

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...

A Language For Agents What programming languages would agents want to program in?
