What?

In the Chernobyl TV series, they think they see a high but (short term) tolerable amount of radiation. It was actually just the upper limit of the measurement hardware and the real value was much higher.

How does a pilot switch between the three modes? Just switches on the dash?

ahartmetz · 9 hours ago

As I understand it, there are no switches because pilots aren't supposed to switch modes, but if necessary, pulling certain circuit breakers will disable subsystems whose failure triggers alternate law. And AFAIU it is documented which breakers are "least unsafe" to use that way.

As the source article describes, it has nothing to do with the First Amendment. The Secretary of Defense is conducting a political purge of the Pentagon. The administration has stated repeatedly and at length that they expect personal loyalty to Donald Trump from the entire federal government, and that they have the right to remove anyone who doesn't show that loyalty or won't do what he wants.

Fucking hell. You know how you turn democracy into fascism? Slowly, then suddenly. It has happened many times before.

Maybe they gave a political donation?

It may also help to push things one way to prevent them from going the other way.

I don’t remember what was used in printed materials. Probably Fraktur as you suggest. In high school we used Latin letters with arrows.

At university in the 1990s, they gave us a photocopied sheet with handwritten Sütterlin and Greek letters in the first lecture. The professor wrote the lecture notes onto a blackboard and we copied them by hand. It was definitely Sütterlin. But I believe nowadays people use Latin letters.

I see, Sütterlin makes sense in handwriting. I don't think I've ever seen that used except maybe as an aside in the intro course where we learned the old conventions (among other things).

I noticed exactly the same thing with Sabine. Her spiral into crankery has been disappointing.

It's very pleasant to see someone else saying it, too. Thank you.

My Hossenfelder experience was: "Oh nice, somebody is getting kind of famous for calling out string theory for being probably hogwash" followed (years later) by "Why is YouTube recommending this dumb clickbait by... Sabine Hossenfelder?! to me?"

Maybe they didn't have to write down as many randomly generated passwords yet and so context always acted as a checksum? Like if I write "its a blue sky" you still know what I mean from context, same as with typos/writos

Whose sky? (jk of course)

Sütterlin was used to denote vectors and matrices in my linear algebra class at university in Germany in the 1990. We got a cheat sheet with all letters in the first lecture (also included all Greek letters).

I still have the sheet. And it’s so weird to see vectors and matrices denoted with Latin letters. I still use Sütterlin.

ahartmetz · 6 days ago

Wasn't it Fraktur in printed materials? I studied physics in the early 2000s and we still learned the convention, but rarely read anything that used it. To me, the incongruity of using an archaic font in a fast-moving science like physics was fun. Probably convenient at the time (early 1900s) because printers routinely had Latin and Fraktur fonts available. Germany was the country of physics around 1900, even the journals were in German! Some of them still have German names to this day (even more so in chemistry), but the contents are all in English.

I can kind of read Fraktur - my motivation was that we had an old (1930s or so) crafts book at home that I wanted to read. I cannot read Kurrent or Sütterlin. Not only do I not know the letters, they all look so damn similar! I would've noticed if these vectors or matrices had been printed in Sütterlin, because I'd have had much more trouble reading them.

They should put AI into a blockchain and have a proper ICO.

Smart contracts sometimes fail because they are executed too literally. Fixing that needs something like judges, but automated - so AI! It will be perfect. /s

Imho, if they're well managed, any private enterprise that is capitalized and has a long term outlook can run circles around public company management that can barely keep a year of marketing strategy consistent, let alone deep technical development.

ahartmetz · 7 days ago

Though, AFAICT, US public companies are the worst regarding financial short-term thinking. It's not as bad in other countries.

It is also possible to make the same mistakes for different reasons: lack of imagination, conservatism, entrenched interests...
