A Snapshot of How I'm Using AI in January 2026

My usage of AI has changed dramatically over the past month, so it was fun to document a snapshot of my current setup.

Haskell community! We need everyone to take the state of Haskell survey.

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.

What's @avi.press of the State of Open Con Advisory Board by Openuk saying about it? Save the dates, 3/4 February 2026, to join the UK's open technology conference, stateofopencon.com

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!

I recently talked about how Haskell is still missing good Parquet support. Excited to see how github.com/mchav/datafr... from @mschav.bsky.social develops, looks promising!

The @haskell.org bluesky account is on fire, hit that follow button.

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!

GitHub - seanhess/hyperbole: Haskell interactive serverside web framework inspired by HTMX, Elm, and Phoenix LiveView Haskell interactive serverside web framework inspired by HTMX, Elm, and Phoenix LiveView - seanhess/hyperbole

Neat!

Phoenix LiveView is really powerful, cool to see those concepts ported to Haskell.

If you or someone you know wants to join me on the @haskell.org committee, nominations are open!

Help us make Haskell the very best language and community it can be.

Nix fails to download build artifacts due to SSL connect error on MacOS Β· Issue #9140 Β· NixOS/nix Describe the bug Certain build artifacts that nix downloads with curl cause an SSL error.

After digging through github.com/NixOS/nix/is..., adding the cert env variable to the daemon's plist seems to have worked!

Hmm now I'm stuck. Seem to be in the same place as: github.com/NixOS/nix/is....

I've tried tweaking NIX_SSL_CERT_FILE, unlinking brew openSSL, reordering my PATH...

We've fixed the permissions but now we have cert issues downloading anything. setting SSL_CERT variables doesn't seem to work. Have removed homebrew openssl links, no dice.

Ok, I didn't have a profile for my user in /nix/var/nix/profiles/per-user. Created them manually

Indeed, things are still messed up. Trying to install something, eg devenv doesn't work yet.

Iterm2. probably not the fastest alternative but I definitely prefer native desktop apps where possible.

Ok I'm just wiping everything, profiles, /nix, and all. Can't fully delete my /nix/.Trashes folder because SIP is on, but hopefully that won't cause issues
