Walking around the compiler bernsteinbear.com/blog/walking...

There is no thriving #Haskell community without its members of the LGBT community, and on that there cannot be any compromise.

Finally an accurate, non-cutesy headline from the NYT about Trump crushing free speech: Trump says broadcasters should lose their licenses for criticizing him.

I did so much programming on a 10.1" netbook that weighed no more than a frisbee (and I did sometimes frisbee it across the room). It couldn't compile large projects fast so there was a lot of coding between compiles. When I miss those days I don't use my external monitor but it's not the same.

Always be walking around the compiler

Great post. And it's been great having Stan on the team!

This summer I started working on Ruby's new JIT compiler—ZJIT, with zero JIT background After two months of learning, I wrote about the questions that puzzled me most: - Where does JIT code live? - How does Ruby execute it? - And more! railsatscale.com/2025-09-08-h...

There are many gems on @b0rk.jvns.ca's blog but one of my favourites is "Some tactics for writing in public": jvns.ca/blog/2023/08...

Newark has every single person go through a mandatory automated face scan before going to security. I asked how to get through without it and an employee told me "cover the camera with your hand I guess?" Horrifying.

Super excited to release the latest version of "A Data-Centric Introduction to Computing" (DCIC). See release notes for 2025-08-27 for what's changed and new (a LOT!): dcic-world.org/2025-08-27/R.... dcic-world.org

Yo dawg I heard you like intervals, so I put an interval in your interval so you can allocate... uh, better bernsteinbear.com/blog/linear-...

What you're referring to as Bluesky is in fact, ATProto/Bluesky, or as I've recently taken to calling it, ATProto + Bluesky. Bluesky is not a social media platform unto itself, but rather another free component of a fully functioning ATProto system made useful by the relay, appview, PDS—

My ahead-of-time JS engine Porffor eliminates JS cold starts on AWS Lambda. 12x faster and 2x cheaper than managed Node. Still very early but these results should speak for themselves :) goose.icu/lambda/

Sure, why not. Here's another post today. Liveness analysis in Datalog! bernsteinbear.com/blog/livenes...

having spiced beans for lunch. have i mentioned how much i love beans? this is sensational

I got a new t-shirt :)

Oops, I accidentally became a benchmark in Kagi's RSS feed parser library

ON BUDGET AND ON SCHEDULE

Nearly five years since the last one, I added a new post to the Compiling a Lisp series. In this post, we tackle lambda lifting and closure conversion! bernsteinbear.com/blog/compili...

"Will I ever use this in the real world?" blog.waleedkhan.name/will-i-ever-...

Well, it happened. I wrote more blog posts this year so far than I did all of last year. And there are a couple more on the way...

apparently trump and his cronies are trying to quietly remove bits of the constitution from public awareness, among others the section that says "habeas corpus shall not be suspended" slrpnk.net/post/25696399

So there's SECD and CEK and CESK and I see one passing mention of CS machines but no more. Why not use CS machines? (Please note I'm very unfamiliar with all of this)

Of the many popular music stars of the 80s, I feel the one most likely to be found—and happiest—playing a country song in a small room with 20 people and just a guitar is Mark Knopfler. (Why yes, some early years' Dire Straits showed up on my recommended playlist this morning.)

New Bismuth VM blog post, detailing the life cycle of a hello world program for Bismuth from high level Bronze code to text-based IR, transpiled C, binary IR, and finally bytecode: enikofox.com/posts/hello-... #BismuthVM #PLDev

corporations have more rights than trans people, so I incorporated as a delaware c corp (this is real, I just got approved)

Roses are red, "Sing" is a verb,

Congrats to the Chrome team for getting me to switch to Firefox. I care more about uBlock than I do about Chrome. Doing the lord's work for the open web :)

Doing a live stream today at 11am Pacific (17:00 UTC) with @bernsteinbear.com! We're going to hack on ZJIT. Join us if you've got time! youtube.com/live/Rm5_aMh...

I know it's been a while, but I'm going to do a live stream this Friday with @bernsteinbear.com! We're going to hack on ZJIT. Please join if you have time! (Also please notice I put a "stream" in the thumbnail for my stream) youtube.com/live/Rm5_aMh...

Great blogpost about partial evaluation / futamura projections applied to WASM: cfallin.org/blog/2024/08...

It has gotten to the point where I wince if I accidentally click a link because it opens up all of my 1699 Firefox tabs across, uh, many windows, and I have to watch them all pop up I should do some house cleaning

this kind of dense, walkable control flow graph is illegal to build in most american compilers

Little known fact: the SpiderMonkey JavaScript engine gets its name from the scene in Twilight (2008) where Edward (Robert Pattinson) says to Bella (Kristen Stewart) "hold on tight, spider monkey"

I feel like if I'm not careful I might get into XSLT

Next in the Datalog series: writing an optimizer. I used e-graphs to get a feel for how they work, and .. debugging e-graph rules is a lot different from debugging Rust. I really like the idea of forcing myself to use it, and teaching it what rules I think I know. github.com/frankmcsherr...

In this ongoing work, we provide a bandwidth efficient solution to State-based CRDT reconciliation with no need for external metadata. We leverage recent developments in set reconciliation after decomposition of CRDT states into sets. Findings also improve general set synch. arxiv.org/abs/2505.01144

Ever wanted to use Ohm from another language? Go, Python, Rust? See the brand new, experimental support for compiling Ohm grammars to Wasm: github.com/ohmjs/ohm/d... It wasn't the main goal, but it also appears to be a perf win — parsing is about 10x faster on real-world grammars (e.g. ES5).

Had a great time with @corona10.bsky.social today!

Are you in Boston and want to hang with #Python people? Boston Python's project & collaboration night is June 24th. It's an informal gathering to talk together, work together, learn from each other, network, whatever. Tell your friends :) www.meetup.com/bostonpython...

The Python Steering Council is pleased to announce that the Free-Threading project is no longer considered experimental! discuss.python.org/t/pep-779-cr...

And here's a blog post, announcing the release! blog.janestreet.com/introducing-...
