Using LLMs for (minor) presentation improvements is one thing, but, increasingly, the problem and solution seem to be mainly framed through LLMs, often in rather shallow and recurring ways.

They were failing for a long time due to changes in database systems, dependencies, and software versions. All thanks to Claude! In the process, Claude also mostly independently analyzed, reduced, and reported various regression bugs.28 Apr 2026 01:56 +0000at://did:plc:athbifpjarvdwfkh422queht/app.bsky.feed.post/3mkji7cebds2phttps://bsky.app/profile/mrigger.bsky.social/post/3mjrswcfsss2zOur proposal for a Shonan Seminar on "The Next 50 Years of SQL" has been accepted! Excited to co-host with Viktor Leis and Jeff Shute in September 2027. We'll bring together researchers and practitioners in database systems, programming languages, and beyond.18 Apr 2026 16:04 +0000at://did:plc:athbifpjarvdwfkh422queht/app.bsky.feed.post/3mjrswcfsss2zhttps://bsky.app/profile/mrigger.bsky.social/post/3midj5ejf2s25Have you ever seen monkeys riding and grooming deer? I have recently contributed the first documented behavior of such a grooming interaction between long-tailed macaques and sambar deer (observed in Singapore)!

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.27 Oct 2025 06:42 +0000at://did:plc:athbifpjarvdwfkh422queht/app.bsky.feed.post/3m45sucnxuc2vhttps://bsky.app/profile/mrigger.bsky.social/post/3m3kia43mc22rWe 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).19 Oct 2025 14:11 +0000at://did:plc:athbifpjarvdwfkh422queht/app.bsky.feed.post/3m3kia43mc22rhttps://bsky.app/profile/mrigger.bsky.social/post/3m3khyx62d22jSuper 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!

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 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.25 Aug 2025 06:57 +0000at://did:plc:athbifpjarvdwfkh422queht/app.bsky.feed.post/3lx7gcqrwks2n
