DuckDB was added to the wall of fame of CWI, next to Dijkstra’s shortest path algorithm, the Atlantic Crossing of the Internet & the creation of Python On the occasion of our 80th (really!) bday Congrats to @hannes.muehleisen.org & @markraasveldt.bsky.social @duckdb.org @cwi-amsterdam.bsky.social

New post on "Proofs and Intuitions": Verifying Distributed Protocols in Veil. We take a tour of Veil, a Lean-based verification framework that combines TLA+-style model checking with formal proofs and enables AI-powered invariant inference. proofsandintuitions.net/2026/02/09/d...

We are organizing the third edition of the "Fuzzing and Software Security Summer School 2026", at NUS on 26th–29th May 2026. We have a stellar set of speakers and will also have a Hackathon. Please share, and/or consider joining! fuzzingsummerschool.github.io/index.html

Thanks a lot to @umathur.bsky.social and Djordje Zikelic (as well as to @93mschwarz.bsky.social) for organizing the second edition of the Singapore Programming Languages Summit! It's great to see the growing community of PL researchers in Singapore. sg-pl-summit.github.io

We are hiring! Suzanne Embury and I are looking for a talented Ph.D. student 👩‍🎓👨‍🎓 to join an exciting, high-impact project on automated testing and bug fixing of Formal Methods tools. www.findaphd.com/phds/project...

Gaetano's paper on Scaling Security Testing by Adressing the Reachability Gap has been accepted at #ICSE26! 📝 gpsapia.github.io/files/ICSE_2... 🧑‍💻 github.com/GPSapia/Reac... How to scale automatic security testing to arbitrary systems?

Had a blast at my first Google Summer of Code (GSoC) Mentor Summit. My personal highlight was speaking with the developers of many important open-source projects and learning about the various challenges they face. Hopefully, we can help address some of those with our research.

We finished the second @icfp-conference.bsky.social/SPLASH hike! We spotted multiple crocodiles, lizards, macaques, mudskippers, various fishes (e.g., archerfish and halfbeaks), birds (hornbills, kingfishers, herons, and egrets), bats, and snakes (oriental whip snake and some a king cobra).

Super excited by the SPLASH ACM Student Research Competition (SRC) results! @junwenan.bsky.social won the gold medal in the graduate category, while Emily Ong won in the undergraduate category! By the way, Junwen is looking for summer internship positions.

A reminder that we will have another @icfp-conference.bsky.social/SPLASH nature walk planned for tomorrow. Consider joining if you are (still) in Singapore! 2025.splashcon.org/attending/ou...

It seems the first hike as part of @icfp-conference.bsky.social/SPLASH went well! A shoutout to @ningkeli.bsky.social and Yibo DONG (as well as my wife, Ting), who guided the participants on this walk. I could unfortunately not participate, as I had to travel abroad due to an urgent issue.

I am thrilled to announce Velvet: a new foundational multi-modal verifier for imperative programs in Lean. Velvet unifies execution, testing, automated and interactive proofs; and is itself proven sound. 💻 github.com/verse-lab/loom 📄 verse-lab.github.io/papers/loom-...

One week until ICFP/SPLASH’25! conf.researchr.org/home/icfp-sp...

First Day: A New Chapter at the JKU It's Wednesday. Is this important? It's my first day in a new position. So, perhaps the real question is: what's going to be important to me from now on? stefan-marr.de/2025/10/firs...

Excited to announce that the Fray paper has been accepted to OOPSLA'25! Work led by @aoli.al with a full pastalab.org collaboration. 📄: rohan.padhye.org/files/fray-o... 💻: github.com/cmu-pasta/fray 🎥: www.youtube.com/watch?v=AX6P...

I will be organizing two nature walks for ICFP/SPLASH (‪@icfp-conference.bsky.social‬)! I did one of them this weekend and was very lucky to see 11 saltwater crocodiles (including a tiny baby one), countless monitor lizards, otters, macaques, fruit bats, various kinds of birds, and fish.

Already registered for SPLASH or @icfp-conference.bsky.social? If not, check out our list of accepted papers: conf.researchr.org/home/icfp-sp... It's language implementation techniques, from debugging and JIT compiling on microcontrollers to visualizing execution patterns between CPU and GPU!

25 years of delta debugging! On this day in 2000, I presented “Simplifying Failure-Inducing Inputs” at ISSTA - now one of the most influential works in the 50-year history of Transactions on Software Engineering. Read all about its genesis and impact at doi.ieeecomputersociety.org/10.1109/TSE....

Do it for science!

Can we statistically estimate how likely an LLM-generated program is correct w/o knowing what is a correct program for that task? Sounds impossible-but it's actually really simple. In fact, our measure of "correctness" called incoherence can be estimated (PAC guarantees). arxiv.org/abs/2507.00057

Looking forward to attending my first database conference, SIGMOD 2025 (‪@sigmod2025.bsky.social‬), in Berlin starting this weekend. We will present four works, all of which tackle the challenge of making data-centric systems reliable, and together have found more than 100 bugs in important systems!

.‪@abhikrc.bsky.social is kicking off the Fuzzing and Software Security Summer School 2025! Looking forward to a week full of exciting talks and tutorials as well as interactions.

🚀 I'll be launching the Formal Methods Engineering Lab (manchester-fme.github.io) – and I am hiring! If you’re interested, feel free to reach out.

Our USING KEY variant of recursive CTEs has landed in DuckDB 1.3 Formerly an off-the-beaten-path researchy idea, now available in a real off-the-shelf DBMS. Hooray! 🎉 duckdb.org/2025/05/23/u...

This is something we've been working on for a while, and now are thrilled to share. Veil: the first foundational framework that combines SMT-based and interactive proofs about distributed protocols, seamlessly, in Lean! Tool: github.com/verse-lab/veil Paper: verse-lab.github.io/papers/veil-...

Our department in lovely Freiburg has an opening for a Full Professorship (W3) on Software Engineering (succession of Andreas Podelski) with a more technical and formal focus uni-freiburg.de/en/job/00004...

How to detect backdoors efficiently? ▶️ Backdoors were found in firmware & open-source code ▶️ Detection requires much manual reverse-engineering ▶️ Fuzzers cannot see backdoors Our @icseconf.bsky.social preprint on finding backdoors with fuzzing is at binsec.github.io/nutshells/ic...

The upcoming ICFP/SPLASH’25 will feature 23 (!!) co-located workshops, in addition to the main conferences, doctoral symposium, Onward!, and SAS, and we can’t wait to see everyone in Singapore in October. Here’s a sneak peek of the hallway track location.

Followed the call of an Oriental Pied Hornbill that lead me to a pair of Buffy Fish Owls. Only my second time to see wild owls in Singapore!

An exciting talk by Armando Solar-Lezama on applying PL ideas for ML, with applications in robotics and computational biology. You can’t do cooler than that. Also, a second SIGPLAN Milner Award recipient giving a talk at NUS in the last two weeks.

One week today is the deadline for expressing your interest to attend Programming Language Implementation Summer School (PLISS) -- we have a great program, if I do say so myself! pliss.org/2025/

Just got back from NUS Research Week. I had a wonderful time. Thanks to @ilyasergey.bsky.social for being an amazing host. Everyone should get working on ICFP/SPLASH submissions... it's going to be a great conference!

The deadline to submit a workshop proposal for ICFP/SPLASH 2025 is **Thursday, January 16** less than a week away! conf.researchr.org/track/icfp-s...

It was a a delight to hang out with these fine friends during the Computer Science Research Week at NUS. My first trip to Singapore - what a city! I'm delighted that #OOPSLA / #SPLASH and #ICFP will take place there in October.
