The machines have hijacked humanity to make more machines. The number goes up by making more machines, so we make more machines, which further influence us to make more machines.

If the WiFi holds up today at Data AI summit I’m going to try doing a code review stream with Devin Petersohn where we walk through the new transpilation PR at 1pm pacific. If your around in person feel free to come say hi! I’ll be wearing my dragon dress with my sports coat

So excited for this zine from @pycon.us

Hey Friends! Snowflake is hiring forward deployed engineers for Snowpark with Spark experience in Menlo Park (Bay Area) and Bellevue (Seattle area). If slaying OOMs, while teaching customers how to run Spark on Snowflake, the posting is at jobs.ashbyhq.com/snowflake/97...

If the Python core team started a weekly/monthly newsletter, what would y'all want out of it? What would make you excited to see the notification in your inbox? @emmatyping.dev and I were brainstorming a bit on this the other day, inspired a bit by @thisweekinrust.bsky.social.

Don’t love how the Waymo’s drive at you while your still in the crosswalk predicting your exit time, like I know it’s what a lot of people do buut it feels like we should do better.

Less than 36 hours before his wife was scheduled to undergo major surgery, NYT personal finance columnist @ronlieber.bsky.social got a letter from his family’s insurance plan denying coverage for the procedure. Listen to his ideas about how we can better handle these denials 🎧 ⤵️

Love to see Moonshine’s edge voice models winning and going to play with the colab next week :)

if you'd like to use the library in python, here is Pete's Collab notebook that helps folks get started: colab.research.google.com/github/moons...

Love to see small models winning, less power greener, faster, and capable of running outside of the hyperscalers :)

Great to see the team directly address transcription accuracy and latency challenges..."attaining accuracy on-par with models 6x their size while running significantly faster." Link to the new Moonshine AI paper: arxiv.org/abs/2602.12241
