I think I'd appreciate a compilation of such surprising facts, if anyone has a list.

I feel like the "falsehoods programmers believe about [thing]" is a little similar, but about correctness and never about performance.

Tech divers are also probably gonna be having a Bad Time. Helium mixes are already pretty expensive, I assume this will make it far worse.

This generates a really annoying features with some browsers. Suppose I want to select "United Kingdom". I open the drop-down and there are all the countries in alphabetical order, plus "United States" at the top of the list. I hit the 'U' key. It does not take me to the alphabetically listed countries beginning with 'U', it takes me to the "United States" entry at the top of the list. I might be able to type 'U-N-I-T-E-D-K' and get to the "United Kingdom" entry, but there are browsers where that does not work. (Nor does repeatedly hitting 'U' bring me to the later 'U' entries.)

This is extremely disappointing. The insurer in question has a very good reputation within the dive community for acting in good faith and for providing medical information free of charge to non-members.

This sounds like a cultural mismatch with their lawyers. Which is ironic, since the lawyers in question probably thought of themselves as being risk-averse and doing everything possible to protect the organisation's reputation.

Well how confident would you be that this part isn't exposed to temperatures above that glass transition temperature? It is installed near the engine.

Well they'll end up with higher prices at night. I wonder if we'll see a shift to energy-intensive processes being run during the daytime.

And before that with gears! (With limited success.)

This article is quite frustrating, since all that it really tells me is that their system "generates thrust without using any propellant and without expelling reaction mass, by directly converting electrical energy into thrust through controlled electromagnetic impulses".

That's rather non-specific. My first thought was that they're using photon momentum, but thinking about that a little harder rules it out. The ratio of energy to momentum doesn't change with any properties of the photon (they're both proportional to frequency) so there's nothing to really develop there: so long as you waste very little power as heat, you might as well be shining a well-collimated flashlight.

Options 3 and 4 from [this paper](https://arxiv.org/pdf/2510.21743), _magnetic sails_ and _solar sails_, seem more promising. Is that what Genergo are doing? I have no idea. The article doesn't tell me.

> But if you offer paid servies, collect money from UK citizens, you must have a business representation in the UK

I don't think that's true at all. You be taking payment by credit card, which doesn't require you to have any local presence.

I think your bigger risk is that you get a judgement made against you by a UK court, which a court that has jurisdiction over you is willing to enforce. I'm not sure under what circumstances that is the case, but I believe that it being the case with libel judgements has been an issue for a while (since plaintiffs can 'forum shop').

How, if at all, would you fund the federal government?

Are you suggesting you don't think the current way taxpayers interact with the IRS is very functional, or you'd like to actually get rid of having any agency responsible for federal tax collection?

Mazdas do lock the screen when in motion.

Actions can be accomplished using a 'big knob' button that can be turned or pressed. The driver can still distract themselves, but I believe it's to a lesser extent that the touch screen.
