scatters··on Ravenchord – A Radical Redesign of the Piano
4ms is 1.4 meters (4'6") of sound in air. That's less than half the length of a concert grand, so at most it would double the latency as experienced by the pianist's ears.
scatters··on The Status Quo Coalition
There are no impartial sources. Oryx estimates a ratio of nearly 3:1, but do you class that as impartial?
scatters··on The Status Quo Coalition
Yes. Given the regrettable failure of Wandel durch Handel, Russia would have attacked sooner or later. As it is, expending mostly obsolete European materiel in a trade for Russian materiel at an extremely favorable ratio, in the course of a war fought off NATO soil with a reduced risk of nuclear escalation, is about the best possible scenario.
scatters··on The Dome: A simple violation of determinism in Newtonian mechanics (2005)
It's the reverse of a point mass sliding up a hemispherical dome. It takes infinite time to reach the top.

A ball rolls through the bottom of the bowl and out the other side. It doesn't come to rest.
scatters··on Just normal web things
Sometimes you can duplicate the tab then open the detail view in the duplicate. I agree, it's ridiculous.
scatters··on Unicode is harder than you think
It depends on the level and domain of your language. A low-level language can get by with just byte arrays. A mid-level language should probably handle at least some encodings, and provide codepoint access. A high-level language should handle locale-sensitive casing and collating, and grapheme-cluster access (note that this depends on the font!).
scatters··on How to Convert Bytes to Grams
You do it at the Planck temperature (1.4e32 K), obviously, giving one Planck mass (22 micrograms) per nat, or 15 ug/b. This probably has some physical relevance, but I'm not sure what.
scatters··on Show HN: Using C++23 <stacktrace> to get proper crash logs in C++ programs
iostream is replaced by format.
scatters··on Underage Enlistment in the United States and the Confederacy
No. You go to the mainland, or, colloquially, the continent.
scatters··on How's the Stack Overflow strike going?
Welcoming and newbie-friendly are not the same thing.
scatters··on Redditor creates working anime QR codes using Stable Diffusion
If you zoom out they are very recognizably QR codes. A commenter made the point that what you're seeing in that case is the low frequency component of the image. Kind of like the Marilyn Monroe / Albert Einstein illusion.
scatters··on A not-so-quick introduction to the C++ allocator model
It's O(1), for high values of 1.
scatters··on C++17’s useful features for embedded systems
> Maybe the language should work the other way around and everything should be constexpr by default and functions should opt out of constexpr-ness, but that's 40 years too late for C++.

That's how lambdas behave in C++, so it's definitely feasible. gcc has a flag, -fimplicit-constexpr I think, that does this for regular functions, and it doesn't appear to cause any significant issues. I think there has been some talk around making this the language behavior at some point in the future.

scatters··on Is this octopus having a nightmare?
It's what's left when you remove any sensory experience. Things happen, and when I wake I have the short term memory that they happened. You could describe it as narrative, but that would imply that there's language involved, and it's more abstract than that.
scatters··on Is this octopus having a nightmare?
Complete aphantasic here. I dream, but not in images or any kind of sensory experience.
scatters··on Ignore Microsoft’s whines about the Activision takeover. The CMA did its job
The UK elects a parliament, and parliament appoints a government. So there's an extra layer.
scatters··on New York to ban natural gas, including stoves, in new buildings
Sure. A heat pump only needs to be 170% efficient to make back the generation losses. As for infrastructure losses, natural gas distribution has leaks as well.

Also, if the power plant is integrated into a CHP system to heat nearby households then generation gets back some percent.

scatters··on Street Votes: A proposed response to Ireland's housing crisis
If you don't want an apartment block on your lot, you don't have to build one! But if your neighbor wants to build one, what moral right do you have to stop them?
scatters··on Australia is quitting coal in record time thanks to Tesla
That's assuming you'd just eat less, instead of eating the same and burning it off at the gym. Or getting fat.
scatters··on New Orleans teenagers found a new proof of the Pythagorean Theorem
Because the first dropped vertical is too long. The left hand angle is beta plus alpha, so it should be ninety degrees, but instead it's an obtuse angle.
scatters··on The City That Fell Off a Cliff
> Before the adoption of "North Sea", the names used in English were "German Sea" or "German Ocean", referred to as the Latin names "Mare Germanicum" and "Oceanus Germanicus", and these persisted in use until the First World War.

scatters··on People had to be convinced of the usefulness of electricity
That was urban-rural migration.
scatters··on People had to be convinced of the usefulness of electricity
When? I can't think of any examples of forced rural-urban migration other than the Highland Clearances in the UK, which isn't really comparable.
scatters··on People had to be convinced of the usefulness of electricity
Neither of those had anything to do with moving people from the countryside into the cities, as far as I'm aware. The Chinese Communist Party is still trying to suppress rural-urban migration (e.g., via hukou).

Or perhaps they deserve to be treated like adults and decide for themselves what infrastructure they want to pay for.
scatters··on Georgia’s big new nuclear reactors could be the last built in the US
The majority of head injuries cycling are to the side, from falling at low speed. Certainly if someone is going at 30mph or above they should be wearing a helmet. But only a minority of cyclists will ever get anywhere near that speed.

> I find it extremely strange that some bicyclists would choose simply not to ride at all just because a helmet is required.

It comes down to convenience. Driving has to contend with congestion and parking, public transport with schedules and stops, cycling with bad drivers and maybe weather. Adding one more inconvenience can swing the balance towards another transport mode.

It's just as well that you aren't making policy, then. People's perceptions make a huge difference to behavior, whether they're well founded or not.
scatters··on Joint statement by the Department of the Treasury, Federal Reserve, and FDIC
What loans? SVB's problem was that its customers didn't need loans, since they had VC money and just needed somewhere to put it.

The rest of the industry is paying. "Any losses to the Deposit Insurance Fund to support uninsured depositors will be recovered by a special assessment on banks, as required by law.". RIP the $250k FDIC limit, I guess.
