Google needs to do better with their weather accent graphics. Dangerously high temperatures should not be shown as “fun in the sun.”
Clip from Google weather page for Phoenix, AZ, showing hourly temperatures of 107-111°F and an “Excessive Heat” warning, with a cartoon below of a lizard hanging out under a beach umbrella next to a desert lake.

Who at Microsoft decided that the default cross reference should be a hyperlink with a complete copy of the caption? Has anyone ever wanted that?! And why, in the 29 years since they introduced this feature, has no one at @microsoft.com realized that normal people just want to insert "see Table 1"?

Reference type: Table
Insert reference to: Entire caption
[checked box] Insert as hyperlink

(3) We took reliability seriously: we started the capacity planning model with 20 "economic" days spanning typical weather conditions, then tested the plan on 7 years of historical weather and added difficult "reliability" days back to the planning model, until it produced a fully reliable plan.

But I saw it here first in a post mentioning the Gary Larson comic.

It made it to the NY Times too.
Screen capture of NY Times article with heading and subheading “Do Cows Use Tools? This One Does.
A pet cow named Veronika can scratch her own back with a broom — the first scientifically documented case of tool use in cows, researchers say.”

Spooky to see Github Copilot jump in with some fairly specific economic concepts as I write comments in my code. I was calculating willingness to pay for a bundle of power across several hours, and as soon as I wrote "relative wtp" it filled in a mostly correct description from scratch.

Interesting. This slide from an Aurora webinar just now shows an ERCOT solar developer covering about 30% of capital cost from post-contract power and REC revenues. That's a bigger bet than I would have expected.
