fun part of this release was me wondering why tf I had marked l as an illegal character only to eventually look down at my keyboard and realize what’d happened

Sorry forgot to include the copilot

Crenshaw's district in Houston is literally gerrymandered in such a way to avoid including Greenspoint, a neighborhood locally nicknamed Gunpoint.

My timeline is basically Metro releases and excitement when Zohran won the mayoral primary (which I guess you missed?)

I haven’t posted much on social media like this for years now. I absolutely think what the Israeli govt is doing is genocide, you just decided to assume the worst rather than ask 🤷‍♂️

I'm very quickly coming around to the feeling that claude code (or other AI tools/agents) generated tests are at least 50% useless. It seems incredibly reluctant to write meaningful tests, often just stubbing things like this.

Spent some time putting together a benchmark project generator for Metro + collecting some real world results shared with me. In short, the results are fantastic 🥹.

Created a dedicated page with details on the doc site here: zacsweers.github.io/metro/perfor...

Big Friday over here
- Foster pup Helga got adopted!
- Raced another mile and lowered my (adult life) best to 4:46 in a big breakthrough
- Finished a huge rewrite of Metro's internal binding graph, runs in O(V+E) complexity now + fixed a few bugs along the way

Endlessly impressed with the work @hossain.dev has done in the Slack Android repo to improve our docsite and make contributing easy. Even down to setting up an auto-approving bot for any PR that _only_ updates docs.

So those Octopus tablets in the back of Ubers are sneakily taking pics of you to see if you’re watching the ads.

Rolled back the years a bit on Sunday and did something I never thought I’d do again: chased a PR. 1:24:24 chip time, 1:23:28 watch split. Sights set on the track this summer now 🌞
