@onthemedia.bsky.social In re: the episode on whether moderates win. First of all, love the show, and I enjoyed and learned a lot from this one. But it had this line, which I hear a lot, and wish I'd hear more interrogation of: "So what really is the prescription for Harris to moderate?"

I'm sorry but the idea that Bari Weiss of all people needs eight bodyguards and a caravan of SUVs to keep her safe from the Woke Mob is going to be a source of hilarious joy for days, possibly weeks

“The end of the liberal world order” is a phrase that gets thrown around a lot in conference rooms and lecture halls. But in war-ravaged Sudan, it’s a reality. @anneapplebaum.bsky.social traveled there and spoke with those who are living in this post-American world: https://theatln.tc/y99eBkQu

The Trumpist Revolution is far closer to the “Il Duce ha sempre ragione” of Italian fascism: “The Leader is always right.”

Turns out taking a shitload of test and HGH provided by a "men's anti-aging clinic" run out of a trailer can't make these guys put the actual work in to hit a minimal fitness standard
SCOOP: more than a third of new recruits at the ICE training academy have failed the personal fitness test -- so many that the agency has had to start pre-screening new hires to weed out what one official called "athletically allergic candidates" www.theatlantic.com/politics/arc...
A Third of ICE-Academy Recruits Are Failing Out
Push-ups, sit-ups, and a brisk jog pose a threat to Trump’s deportation campaign.

Our No Kings protest was absolutely massive, given how small our town is--OVER 5000 people! We made the local news!

We would have been happy with just 1000!

Posted the news story to Nextdoor and pissed off a bunch of Trumpists in the area. Secondary benefits.

Ashley Parker: Donald Trump “is always trying to get through the minute, the hour, the day, the week. And he is trying to win over whoever is directly in front of him … And it will make him say things that don’t make sense, that are in contrast with each other.” #TAF25

My best friend's dad is Argentinian. He fled the country because most of his close friends were disappeared, and he still has terrible PTSD and survivor's guilt today. Ask someone who grew up during the Years of Lead whether that was fun. That's where civil conflict gets you.

The big reason I'm trying to hammer "civil conflict/political violence" here is because I've spent a substantial chunk of the last five years looking at mass graves. I want a society where people aren't plotting to kill their neighbors and throw them into one. That's where all this can lead.

Finding insights into the Josephus problem by employing base-2 expansions. This leads to a case-study in using the repertoire method, for proving a hypothesized solution of a recurrence relation.
