In this month's EGRAPHS Community Meeting, Leo de Moura will present on the internals of the `grind` tactic in Lean 4.

Join us on Zoom 9am PT this Thursday (9/18). Or catch the recording after!

I had a great time at Kris's workshop in May! Lots of inspiring talks and discussions. He has posted a mega-video of all the recorded talks, I highly recommend checking some of them out if you're into Datalog, logic programming, or incrementalization. There is even some e-graph stuff in there!
May 25-27, 2025, I hosted an event, the "Minnowbrook Logic Programming Seminar," in Blue Mountain Lake, NY. I recorded 11 talks on Datalog-related interests, totaling over 9+ hours of video, which I have just now published on YouTube youtu.be/3ec9VfMUVa8

I'm at PLDI 2025 right now! Come say hi if you are too :)

Lots of cool e-graph stuff happening this week: the egglog tutorial, the EGRAPHS workshop, and some excited papers. I'm trying to collect it all here: www.mwillsey.com/blog/pldi-2025

It's that time of year! The submission site for the EGRAPHS Workshop is open!

We welcome talk proposals on published work, in-progress work, real-world applications, and anything in between. Get your 2-6 page abstract in by **April 17 AoE**!

The EGRAPHS seminar series resumes Thursday 9am PT on Zoom! See you all there.

Cole Kurashige will be presenting on C.C. Lemma, a prover featuring induction and lemma discovery in e-graphs.

HYTRADBOI was the best bang-for-my-buck (both in time and money) event that I attended last year. This year looks equally great! If you are interested in PL or DB, it's worth it; if you like both it's a must see!

Sidenote: I think it's a great example of how to run an efficient remote conference!
The program is up and tickets are live at www.hytradboi.com/2025/#program.

I'll keep updating this thread as the last 10 talks hit camera-ready.

☕️ We’re running LATTE again: our ASPLOS workshop about languages/compilers/tools/whatever for hardware design.

Submissions are just little 2-pagers, due on January 31. Plenty of time to throw something together! capra.cs.cornell.edu/latte25/

It's 2025, which means PLISS is this year... May to be specific! If you're interested in studying programming language implementations, please make sure to express your interest in time pliss.org/2025/

Just wrapped up grading for grad compilers! It was a ton of fun, and I hope to keep iterating and improving the course! hat tip to @samps.phd for the Bril infrastructure!

Some students have opted to make their final projects public on the course site, so check them out!
