We walked that back, sorry. http://eel.is/c++draft/diff.cpp20.lex#1

  Change: Previously valid identifiers containing characters not present in UAX #44 properties XID_Start or XID_Continue, or not in Normalization Form C, are now rejected.
  Rationale: Prevent confusing characters in identifiers. Requiring normalization of names ensures consistent linker behavior.
  Effect on original feature: Some identifiers are no longer well-formed.

> I don't know how recent those versions are

gcc 14 has not yet been released; going by past years, 14.1 should come out around the start of May (2024). clang 17 was released September (2023); note that you need to use libc++ (stlib=libc++), not libstdc++. VS 2022 17.7 has been out since August.

A radially symmetric object does not produce gravitational waves, whether it is spinning or not, since it has zero quadropole moment.

The Remington No. 1 - which introduced the QWERTY layout - omitted number keys for 0 and 1; the O and I letter keys were considered sufficient. The No. 2 added a shift key, and a full number row.

    ceil(0.000001) = 1
    ceil(0) =... 0? Wtf?

But that's a perfectly well defined function. Not every function has to be continuous.

Is there outrage when a clothes store puts the items they haven't been able to shift onto the sales rack? Is there outrage when a grocery store puts discount stickers on the food that's approaching its sell by date? Dynamic pricing is a fact of life in very many sectors.

Sticking gold in a vault is only a means to saving if you have a reasonable expectation that when you take it out you can use it to obtain goods and services. It is thus a disguised claim on future production, and so relies on debt to exactly the same degree as bank money.

I'd be happy if they have an easier and safer commute because everyone else is staying home.

No, they couldn't. One person's savings is another person's debt. If everyone tries to save then no one can; this is the paradox of thrift.

The Russian rouble was not free floating prior to the crisis. They tried to defy the iron triangle and paid for it. This is not a problem for the USA, since other currencies are denominated in terms of the dollar.

The reason it would be impossible for the US to default is that the US is not significantly in debt. Most of the federal debt is held domestically, meaning by the US. You can't be in debt to yourself.

It exhibits two distinct constructions both of which demonstrate that n^2 + 2 unit equilateral triangles are sufficient to cover an equilateral triangle of side n + ε. The obvious area argument shows that at least n^2 + 1 are required.

A small modification of the second figure can show that for any non-equilateral triangle, n^2 + 1 such triangles will cover a similar triangle of length ration 1 : n + ε; it remains (as of 2010, at least; see [1]) an open problem whether a construction of n^2 + 1 triangles exists in the equilateral case.
