I write code, delete email and forget to go to meetings at Meta, mainly on glean.software. Spare time: bikes and mountains.

Blog post: Indexing Hackage: Glean vs. hiedb simonmar.github.io/posts/2025-0...

submitted 3 days ago • 0 comments

I'm thinking about a second edition of Parallel and Concurrent Programming in Haskell. Any thoughts on what should be added (or removed)? What's missing, what updates are needed to reflect common usage? The obvious new things are async and Haxl. Should the chapter on distributed-process be kept?

Yesterday I left Meta after 12 years. Freedom feels good!

If you have a bytecode interpreter and you want to make it faster, do you (a) JIT it using LLVM or (b) use Wasm or (c) something else? Given that LLVM is already a dependency (and dependencies matter), but you would like sandboxing/safety too.

I sometimes get compliments on my laptop stickers in meetings. Especially the one in the middle, which I tracked down after seeing it on my daughter's laptop (and who now insists on getting credit for it, ergo)
