You may be thinking of the Conservative Party rules for a leadership election, which does start with a number of MPs writing to the chairman of the 1922 committee to say they have lost confidence in the leader. Labour rules are very different.

An _awful_ lot of Labour MPs would have to vote in favour of such a motion, and quite a lot will lose their seat in a General Election.

They did indeed update it. It was originally about the anti-Streeting briefings, and now it says Mandleson. It felt like a piece from weeks ago that was written in case he did resign.

Ahem. "rising to Β£7B" of course.

First estimate of the cost for a Scottish parliament building: Β£40M (1997). Final cost: Β£414M (2007). That's about Β£700M in today's prices. So an initial estimate of Β£700M rising to Β£1B?

@davidallengreen.bsky.social You are not a mediocre writer. (I have no idea how many followers you had on Twitter.)

Errr, not necessarily. Halley Research Station (one of the BAS bases) is on the Brunt Ice Shelf. The ice flows off the continent, and floats on the ocean for hundreds of miles.

Send them Andrew Mountbatten-Windsor instead?

He will not be booed; that would be unforgivably rude. The closest he will come to being booed is someone saying "that is an _interesting_ point of view". (Translation from parliamentary language: "you are fucking batshit insane.")

I'm not convinced oil being priced in dollars is quite so beneficial to the US as the thread suggests. If the US treasury prints too many $s, the value of the $ drops, and the price of oil (in $s) rises.

Maduro is not a nice person, and is not the legitimately elected president of Venezuela, but after the raging success of regime change in Iraq and Libya I'm not sure what Trump goes to achieve. Distraction from Epstein files, and terrible polls perhaps?

Damn! I replied to the wrong message in the thread, didn't I. Sorry.

It wasn't technically moon _crossing_ but at closest approach it would be 80Mm from moon and 300Mm from earth. My Nuffield Physics estimate gives earth's mass 80Γ— greater, but moon about 4Γ— closer, rΒ² means 16Γ—. So moon's gravity is about 20% of earth's. That's plenty to disrupt the orbit.

... and Germany. "Jonathan's legacy" is a dead link, but that's either deliberate (you ain't dead yet), or a different problem

Given how awful the British Empire was, it never cases to amaze me how popular we at these days.

"Cryptography is the study of how to turn a given problem into a key management problem" (I can't remember where I read that: from you is a very likely answer).

There's an awful lot of hand- waving above, but it should give you some sense of what is going on.

A quantum computer can reduce the effective length of a ppk key to something like the logarithm of its length. So a 4096 bit RSA key ends up with effectively 20 bit length. That's about a million guesses to get the right answer, which isn't many.

It turns out that quantum computers can be used to efficiently search for values with a given property (e.g. a number which is a factor of this number). That makes current ppk algorithms (RSA, EC) vulnerable.

12.11.2025 19:07 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

Ppk algorithms all depend on an operation that is easy to do one way (e.g. multiply two large primes) and hard to do the other way (e.g. given the product, find the two original primes). Symmetric algorithms don't have this sort of structure.

I'm sorry. I don't see a problem here? (I don't count the need to pour some in to a glass before you enjoy it as a _problem_.)

I always wear socks with shorts, (and of I'm wearing shorts, I am wearing sandals or walking boots too). I am very disappointed to hear that at least half of this is fashionable.

I know many Greens find the following heresy, but I found Natalie more inspiring than Caroline Lucas when she came (as leader) and talked to Cambridge Greens
