What are they going to learn? That’s it’s by far the best fixed-size approximation to real number arithmetic we have, sufficient for essentially all of our scientific and engineering needs?

There is no such thing as “supply and demand” in a market dominated by collusion.

There’s also engineers’ belief that they have learned the language despite only half-knowing it at best.

> Yes: OSX on ARM64 has alignof(max_align_t)==8 and alignof(__int128)==16. And malloc only provides 8-byte alignment, so if you're using types that require 16-byte alignment, you have to call aligned_alloc. Also, the stack is only 8

It's actually worse than that; from what I can piece together of the history: 1. the people at Intel who originally implemented `_BitInt()` made `_BitInt(128)` eight-byte aligned 2. the x86_64 psABI document was updated to agree

_BitInt(128) is a C(23) type and has all of the same problems plus a few others.

The rolling method is really exactly the same thing, but some people find it easier to think about reaching in for the corners after rolling, and you don't need to be tall enough to let it fall down into place (wife is 5'4" a

The standard joke here is that the researcher objects to the need for a trial, saying “that would be condemning half my patients to death!” and a medical student asks “which half?”

The readme doesn't explain much, but the introduction to the paper itself is quite approachable. As for whether it's groundbreaking or not ... it's a neat readily-accessible constant-factor improvement for area-constrained fi

It doesn't matter how far down it is. It has some constant index independent of the problem size, so for "large enough" problems, it's just a constant factor on the time required.

The handwavy explanation is you can enumerate a list of all the turing machines. You run the first one for one step, then you run the first two for two steps, then the first three for three steps, etc, until one of them halts. If P=NP, this

Yup. College towns are especially great for this, because college kids walk all over the place, so there's a critical mass of pedestrians and drivers expect them. We live in Hanover NH, and packs of six-year-olds run all over our neigh

If njuffa and edp have weighed in on a floating-point question, it is canonically answered (if you're really lucky you might sometimes get one of the French to join in, but any combination of 2 suffices).

Yes and no. We had a smallish (8lb) cat who brought us a dead rat every day for years. We had a graveyard with thousands of rat skulls. These were “normal” sized rats though (~0.5 lb), not enormous subway rats. Our current (20lb) cat only h

Swift ran into similar difficulties with noalias. Happily the bad cases I was tracking that inhibited optimizations were resolved in the last year or so. There’s probably still some lurking corner cases, but the overall situation is pretty
