Throwing nice round pizzas is definitely not my forte, but it's still fun as heck. (Had leftover biga for making bread yesterday so decided to turn it into pizza dough today.)
Mixed greens, mozzarella, and beyond meat hot Italian 'sausage'.

Having fun w/13yo, who expressed interest in baking bread.
(The biga-based rustic bread recipe from Peter Reinhart's "Crust and Crumb").
We didn't have bread flour on hand, so the crumb is a little small, but have some for next weekend.

Farewell to the garden part 3: fried green tomatoes. (They taste better than they look. 🤓)

7yo Semi-Seriously said he wanted to learn algebra, because his big sister is in algebra 2 and he wants to do everything they do. So I've decided it would be amusing to try -- we'll just have to dynamically learn all the math leading up to it as we go. 🤣

Trying out real lifting shoes for the first time instead of either flat no-sole vibrams or just really stuff heeled shoes. Haven't lifted in them yet, but they feel super weird - it's like the toes are glued to the floor. Very intrigued to do squats on Friday. 🤓

For #pittsburgh power stuff: Duquesne Light has released the updated rate schedule starting Dec 1. Overall about a 6.6% increase in prices (more if you just look at supply charge). The percent potential savings from using time-of-use billing stay the same but the absolute amount increases.

Fortunately, the garden has good taste.

This is the best Watson obituary I've read.
A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

Mmm. Just had the best arepas and tostones I've ever had (this isn't a high bar, though). Arepittas in downtown #pittsburgh. Little hole in the wall. Freaking tasty. And the kids menu is perfect.

Advantage of being a kid in the 80s: Associating the theme song from Peter Gunn with the video game Spy Hunter, not the original TV series.

Science Bluesky, I need a question answered that is not yielding to Google!
Can you carbon-14 date an alien?
Because I know it requires nitrogen-14 in the upper atmosphere and if the alien homeworld doesn’t have the same nitrogen content…?

The solution to the male loneliness epidemic is attending a local Democratic Party canvassing event.
WOW. 81% of women 18-29 voted for Mamdani, 80% for Sherril, and 78% for Spanberger.
Gen Z women aren't playing around.

why is this mayoral election different than all other mayoral elections?
in all other mayoral elections, we get to see andrew cuomo lose but once. but in this mayoral elections, we get to see him lose *twice*.

This is the local election I was most intrigued by. Embrescia isn't a bad guy, but Rose running as an independent and winning feels like a bit of a finger in the air.
(The republican mayoral candidate, in contrast, never stood a chance, and, um, rightfully so.)

So, because the Allegheny County, PA (Pittsburgh) Council mandates seats for minority parties, the Democrats were never able to unseat at-large Republican Councilman Mike Embrescia.
So, they ran a left-wing Independent and he's winning easily!

I'm trying not to repost too much of these because we're already flooded with them, but: what's happening in Chicago - and elsewhere - should make us all feel sick. The minimum possible is getting our asses out the door to vote tomorrow. Exercise power or lose it.

In Chicago, a woman was driving to get coffee when a DHS vehicle fleeing an angry crowd crashed into her car. Armed agents jumped out of the vehicle, yanked her door open, pulled her by the legs out of her car at gunpoint, held her incommunicado for hours, then released her with no charges.
