Some days, I decide what to cook. Other days, the garden decides what I shall cook. Today was one of those days. Happy fall!
(Thanks, garden, you did well this year, we'll miss you.)

Quite enjoyed Quantum Theater's production of "Enron" last night. It's interesting how much things echo.

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!

Reminder, polls in PA are open until 8, and if you're in line by then you're still good to vote. Exercise that power.
Hey Pennsylvania! It’s go time! Vote yes to retain the justices and protect your rights, fair maps, healthcare access, and more because #PACourtsMatter! Go to bluevoterguide.org and see what other races are on your ballot. Polls are open from 7:00 am to 8:00 pm.

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.

if there was a rich person with the will, you could build the most incredible news organization that has ever existed just from the wreckage of this year alone.
I was laid off from Teen Vogue today along with multiple other staffers, and today is my last day.
certainly more to come from me when the dust has settled more, but to my knowledge, after today, there will be no politics staffers at Teen Vogue.

Zohran picked 「卓蘭」("excellent orchid") for his first name and「夸梅」("brilliant plum") for his middle name.
The orchid and the plum are among "The Four Noble Ones" in traditional Chinese art, the former symbolizing an indifference to fame and fortune, the latter an indomitable, incorruptible spirit.

I continue to wish that the bsky UI provided clear notification when a blocklist adds someone you follow / you subscribe to a blocklist that blocks someone you follow. Or, more vaguely - when a blocklist "changes" in some substantial way, which I realize is very vague and hard, but maybe worth a try
I'll add a little nuance to this, though I do understand this point: people don't often understand what they're doing when they subscribe to a blocklist. The mental model of how blocklists work is often fundamentally incorrect, and grants far more power to maintainers than they intend.
the anti blocklist discourse always devolves into people either yelling or passive aggressively hrmphing YOU SHOULD LET ME INTO YOUR HOUSE and
no?
i dont have to.
i dont have to explain why.
if i fuck up and miss something i would have liked to know that's on me! im an adult!
good talk!

I'll be showing up on Tuesday to vote YES to retain our judges in Pennsylvania! These PA judges have been protecting our rights, and it's important to return them for another term.
No need to remember names -- every statewide judge on the ballot is good! All are recommended by the Bar Assoc.

My alter ego is having fun watching the Susquehanna unit 2 plant recover from its unexpected scram the other day. nRC's status pages remain a little glitchy
It's a little hard to see in these graphs but nuclear generation at susquehanna has returned to about normal. If we zoom in on total nuclear generation, you can see it (note that the Y axis does not start at zero so we can see the detail).
The NRC status page didn't update today though. :(
