Had a nice day co-hosting the first hike of #icfpsplash25 Outdoor Activities track with Yibo🙌

Walking in the forest 🌳
Seeking special animals (monkeys🐒, lizards🦎, colugos🦇, and even a snake🐍!)
Enjoying the networking🥳

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.

An opening theme from the Outlaw Star series has just randomly started playing in my head, and now I am fighting the urge to rewatch it.

It's official: RTFM, the faculty mentoring workshop, is happening again, this time at POPL 2026 in Rennes. The one we had at PLDI 2024 in Copenhagen was well received, so I'm looking forward to the next edition. Stay tuned!

"Pat, why do you carry that ridiculous 600mm lens on long hikes?"

Buddy, I can see mountains reflected in the eyes of a trailside pika.
A pika sits on a mossy rock. Tighter crop of the same pika, focusing on its head. An even tighter crop, focusing more on the pika's eye. An extremely tight crop of the pika's eye, emphasizing their reflection of an early morning mountain scene.
