Because i hope the underlying discussion about programming languages will push Haskell in the direction I’m advocating for.

I haven't been using bluesky much these days but I realized this platform would probably enjoy roasting us for this the most, so re-posting here: avi.press/posts/2026-0...

scarf-js is now at 4M weekly downloads on npm and growing quickly. This is your periodic reminder that telemetry in OSS when done properly is Good, actually.

If you're at OpenSearchCon today, I'm giving a talk at 11:25, uncovering lessons from billions (and now, trillions) of open source downloads. Hope to see you there, it will be fun!

Claude 3.7 for most things. I do see a lot of people saying grok 3 is very good for coding but I haven’t tried it myself. Also unsure how that integrates with all the tools

Hashicorp did a controversial relicense of some of its OSS. Redhat never did anything like that. Both had great sales to IBM.

I did a double-take on this Haskell Foundation update. Looks like there is another one besides @haskell.org ! This HF also looks like it is doing Good work.

This is a remarkable milestone for us. 10 billion events across OSS documentation views, downloads and telemetry. *0* records of PII are stored, preserving user-privacy even from Scarf itself. Better usage visibility for OSS maintainers -> more sustainable OSS for everyone!
