Top Trump officials rush to purchase nuclear war-proof bunkers after Iran attack: report Since President Donald Trump’s unprecedented attack on Iran last week, at least two top Trump administration officials have raced to purchase their own survival shelters designed to withstand an apoca...

A dude in Texas who makes bomb shelters for nuclear war has seen his business skyrocket this week.

Recent clients include 2 Trump admin members, and the rest were almost all “Christian, conservative CEOs,” which included “several of the wealthiest men on the planet."

‘The Most Dangerous Man in the World’ Mojtaba Khamenei, a candidate to succeed his father as Iran’s supreme leader, is no reformer.

"One acquaintance of Mojtaba Khamenei, the 56-year-old son of Ali Khamenei, told me that he was the most dangerous man in the world and considerably more violent and ideological than his father. One thing Mojtaba is not is a religious scholar."

Let's talk about what happens when oil prices go through the roof and stay there - because it really isn't pretty, it's going to hit our economy incredibly hard, and it's only peripherally about how much it costs to fill the tank.

A short 🧵

I agree, homework can be useful if various conditions hold.

If I understand this correctly, in other words if you knock on 2000 doors, and 1000 people answer, and the number who were going to go out and vote was 400, you just increased that to somewhere between 412 and 420.

That's a long hard slog for those extra 12-20 votes.

THREAD: I got laid off from NYMag/Vulture after 14 years. The family lost 75% of income + medical. Now mzs.press bookstore, once a side project. is do-or-die for Judith & I. I feel weird telling you this because others are doing much worse. But if you could like or share this, we'd be so grateful!

Less homework is not the cause and more homework is not the solution to any problem we have in education at present.

I have a 50 year old tape and I’m afraid as soon as I play it, it’ll get eaten by the machine. Any advice?

Hello Bluesky.

If you like Improvised Music/ Free Jazz, you can hear and buy it on my records here:

I haven't released a new record for a while - I'm benched as a trombone player while I recover from hand and arm surgery, but my music lives on!

Reasons a cis women might have Y chromosomes:

- Twin brother
- Gestating a child with a Y chromosome
- Bone marrow transfusion from someone with a Y chromosome
- Being intersex (we know of XY women who have naturally conceived and given birth)

#Woodensday Both myself and @portaspeciosa.bsky.social taking a closer look at these handsome lion lectern feet in Wells cathedral.

To the left, a very smart little podium, cosying up to its companion eagle lectern! @notpodium.bsky.social

I can't believe you've risked enraging both sides of the lectern podium debate!

OTOH you clearly know your stuff so have nothing to fear.

I think he deleted one reply. But I would guess HTML is what he's thinking of as a better choice. It was mentioned in the first post and does play better with screen readers than PDF.

Totally fair.

I think state of the art PDFs are one thing, but it will be a long time, if ever, that run of the mill ones will be accessible.

And none of that even addresses reformatting/reflowing which by definition is kind of the opposite of how people think of PDFs.

I don't think of it like unchangeable, but rather "this is what I'm going to print". So using it for worksheets, exams, handouts, etc., where I need to see how stuff fits on the page.

Meet Tatu and Loulis—the last of the 'talking' chimpanzees In the 1960s and '70s, a group of chimpanzees astonished the world by learning sign language. Only two remain, and one question still lingers: Was it worth it?

Books by and about Women in Mathematics Checkout out this list on Bookshop

International Womens Day is this Sunday, so I thought I'd compile a list of books by and about Women in Mathematics.

The most important question I have for you is: What's missing?

"misinformation spread by those who have fancy letters and affiliations affixed to their names is demoralizing"

is a fucking hilariously desperate framing

"accredited experts disagreeing with me by citing studies and knowledge within their field of expertise makes me sad"
