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!
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
Idk about tiple dot access. You can count in a few ugly ways: lukaswirth.dev/tlborm/decl-....
Tuple unpacking is a little neater.
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**!

This month's EGRAPHS seminar is on Slotted E-Graphs! The authors will be presenting on new ways to add support for binders to e-graphs.

A screenshot of YJIT latency over time, showing that p99 latency stays lower than MRI even during deployments.
The first few HYTRADBOI 2025 talks are ready! I'm so excited to be finally able to tell people about them!
Talk #1: A YJIT interview with Maxime Chevalier-Boisvert
The EGRAPHS workshop brings together researchers and practitioners that use e-graphs and related techniques. The paper submission deadline is on April 17. More info can be found here: pldi25.sigplan.org/home/egraphs... and egraphs.org
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!
☕️ 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!
