hey spatial folks: if anyone has a great "parquet versus zarr" write-up, let me know. I'm never going to write a serializer but I'm really interested in the performance impacts of format for cloud downloads 👀

Hey @universalhub.com does this qualify as storrowing?
Holy shit this big truck just got stuck under an overpass on Mass Ave in DC. I've never witnessed this before but thought about it a lot as a kid (lol).
You can't see it but there's a police car behind the truck under the bridge, diverting traffic to one lane.

Saying he can more positively impact the city by dropping out is the first time I've agreed with Kraft
JUST IN: Josh Kraft is dropping out of the mayoral election in Boston.
This means that Mayor Michelle Wu, the progressive incumbent, is certain to win a second term.

Ant queens of one species produce males of another species, so she can then mate with them and produce hybrid workers!

PhDs are job training programs. Understand what job you want when you get out, and how spending somewhere between 5%-10% of your total life making almost no money will help get you there.
You owe it to yourself to be brutally honest here: what are the odds? What do you need to do to improve them?
