@simontatham Reminds me of my bashism for a new maildir:
$ mkdir ~/Mail/name/{,cur,new,tmp}

@daniel_bohrer It's "brace expansion" in the bash man page, and it can also do ranges: {1..9}, {a..z} etc. I'd been using bash for at least 15 years before I found out about it by chance.

@Lana But where can I get a shopping trolley with a 90° twist in it like that?

@eldadoinquieto @nyrath @kaia Tamper-evident is a lot easier than tamper-proof, and still useful. "OK, don't use this codebook."

@futurebird A favourite book of mine is The Bermuda Triangle Mystery—Solved! by Larry Kusche. It's dressed up in all the standard woo presentation, but it's simply a list of incidents and surrounding data. Here is "the ship that vanished in calm seas", and next to it the island newspaper saying "biggest storm ever last night". Here is the vanished Navy flight, and next to it the comment that it was a navigation training flight, the sort of error that was common, and evidence to show that probably they were where that error would put them. And so on. It's completely deadpan and completely remorseless, and it should cure Bermuda Triangle belief forever.

@mjg59 I have certainly known people who recused themselves from working on free implementations of stuff they'd written commercially, to reduce the chances of lawsuits later.

@kaia "What is behind me is not important."—Juan Fangio. But he was a racing driver.

@goatsarah Also so is "AI", often involving the same people. I mean, Elon Musk has got involved, that alone should tell you it's all hype.

@thomasfuchs PSA for UK peeps: please don't forget, your government wants you to get sick and die.
