Hey: You know that thing that every time I think about it, I get mad? What if I sat and thought about it for kind of a long time

Really smart piece on how to think about democracy amidst the failure of shared knowledge.

It is 5:26pm and the sun is setting and I pretty much just want to stare at the ceiling and dewrinkle my brain for the next four hours

The thing that will absolutely drive me to madness is when a new element on a page loads while you are clicking on something, and therefore everything shifts just enough to make you click on something different to what you were trying to click on. Google Drive is a prominent offender.

So on Epstein, the Democratic position should be "Trump should resign." If you are a Democratic elected, practice saying "We demand the president's resignation" in front of a mirror as many times as it takes until the dry-heaving that comes from having a phobia about actually doing politics passes.

remember, remember, the 12th of November, the dynamite carcass and plot
It’s 12 November, so it’s time to mark the 55th anniversary of the exploding whale of Oregon, an attempt to clear a cetacean carcass from a beach which prompted one reporter to say “The blast blasted blubber beyond all believable bounds”

BREAKING: The Dallas Mavericks are expected to fire Nico Harrison, sources tell The Athletic.

The former Nike executive drove the decision to trade Luka Dončić to the Los Angeles Lakers eight months after Dončić led Dallas to an NBA Finals appearance.

I have to hand it to them, it's an incredible bit to publicly lose a game of chicken, admit that's what happened, and then spend the next day lecturing everyone about courage and tenacity

This is where I think hockey can take something from soccer: specific names for the *ways* different people play what is nominally the same position. See, e.g., trequartista / enganche, destroyer, pivot, anchor, shuttler.
The more important "cultural" aspect, though, is that we need a broader and more varied set of "types" to be able to talk sensibly about the players we've actually got in the league. Naming things is hard, though - "transition defender"? "blueline machine"? "ice tilter"? Something like that.

Teaching friends, advice please? I have this calculus student who fancies himself a hotshot. During group work at whiteboards he often takes charge, assumes a teacher role, and lectures other students. Other students have told me that they find this condescending and don't want to work with him. 1/

How about we shut down the government for this very popular and specific goal and then, hear me out, we hold out for like a month and a half and then, ok this part is important, after a watershed election where we ran the table, ONLY THEN, fold and don't get the one thing we said we wanted.

Retire bitch
Democrats have been fighting for months to address America's healthcare crisis

For the millions who will lose coverage
For people with cancer who won't get the care they need
For working families who can't afford to pay $25K more a year for healthcare

We will keep fighting
