this was a crazy find for foodcoop.news. turns out somebody else has also been taking snapshots of the produce prices… since 2013!

and it was @johnresig.com!?

god bless vidalia onions for leading me onto this trail. incorporating this into the site very shortly

Some progress from @recursecenter.bsky.social: we have a lovely study group doing Stanford's CS336

The material (from just three lectures) has been so great in building intuition for all the different model matmuls

After 2 weeks, I implemented the transformer architecture in ~250 LOC 🤯

I made a mirror of the @foodcoop.bsky.social shift calendar to a shared Google calendar. It gets synced every five minutes.

You can now search open shifts against your personal calendar! Hoping this is a more convenient way to plan your coop labor 😇
