Playing with some vegetarian Wellington ideas. I like Kenji's but it's a big pile of work. This one uses a lazy arrangement of puff pastry filled with beyond steak + seitan, braised leeks and carrots, topped with mushroom duxelles.
Not quite the Wellington look but tasted good.

a lot of people don't realize that Christmas carols and traditions are actually folk memories of suppressed pre-Christian events, namely the end of the Third Age and the Fall of Sauron.

I wanted to do something different this year and my friends suggested fondue. I loved the idea, so here we go!

Macedo and Lee misrepresent what actually happened during the pandemic and are unable to confront Covid's actual toll, presumably because it undermines their premise. A longer take here w/my colleague Greg Gibson:

And even relative laggard PJM (hi guys) is following the trend - 2025 was a good leap for us. Our total is still low compared to most other parts of the country but our trend looks really good.

This is interesting and thought-provoking and god, Magda, I'm sorry you're the one having to deal with having this asshole in your department even though I don't know which way I feel about the legal decision without a lot more thought. 🤓

Interesting and important 9th Circuit decision about the free speech rights of professors at public schools, just won by FIRE, likely to be subject of culture war disputes.

Interesting! We got our first #pittsburgh parking ticket by mail today (no physical ticket on the car). Makes sense, though it lengthens the feedback loop between violation-response, but I bet it's faster & safer for the meter readers.
Now if only they could just deduct the ticket automatically...

Doh. This will have little effect on people outside of the time community (unless folks set a boulder nist NTP server as their only choice, which would be unwise). but it's going to be a lot of un-fun extra work for nist folks. Wonder if it temporarily breaks NIST's calibration service TMAS, though.

Copy-pasting of citations is already bad enough -- it creates a game of telephone that can end up misrepresenting the original work. Don't trust ai on citations. You should be reading (skimming at least) the cited work anyway to be certain it says what you're referencing it for.
I’m sorry, but it is disgraceful to be an academic who uses this technology to conduct research. It should be prohibited in all of our scholarly institutions, including universities and journals.

Only saw two stuck city buses getting the kids home from school, so I guess it could be worse. 🤓

I think I'd prefer a Waymo to a human-driven cab*, but you'd have to pay -me- to get in a tesla robotaxi.
* (I do not have enough information to have a strong personal opinion about whether Waymos are actually safer than humans _under identical circumstances_, but it's plausible.)

"data suggests Tesla Robotaxis are crashing once every 40,000 miles, whereas the average human driver in the US crashes about once every 500,000 miles"
that's just really really bad sherwood.news/tech/teslas-...

Tesla’s 29 Austin Robotaxis have crashed 8 times since June, as data suggests they perform much worse than human drivers
That’s a lot of crashes for such a small fleet....

For unavoidable reasons we ended up driving to the North hills, back through the city to Edgewood - on a steep hill that we saw another car fail to climb - and back home. In 3-4" snow. I learned:
