A quick look at a topographic map of California suggests HSR through the Central Coast would be significantly more expensive, especially the southern half. Moreover, the Central Valley has more than 3x the population and significantly more

My first thought is that what's different here isn't async, per se, but parallelism. io_uring uses a kernel thread pool to service I/O requests, so you actually end up with multiple threads running in parallel handling bookke

It's difficult to know specifically what ordinary folks believed, let alone the literati. But as you said, even today people mix religion and politics even when they at least superficially understand them as distinct and separable. I t

Well, modern science wasn't a thing, per se; would have been part of natural philosophy and not well delineated. But philosophy, religion, and magic were broadly speaking understood as distinct, similar to today, at least from the pers

AFAIU, in Ancient Greek culture Magi were often considered like Plato's Philosopher Kings. Greeks didn't have an accurate understanding of Zoroastrianism or the structure of Persian government, but for some reason they saw Persian

Except primers have lead, dusting your hands and face with lead, which I wouldn't be surprised if worse than ingesting some lead shot. And it's far more difficult to find ammunition with lead-free primer than lead free bullets.

Yeah. I always disable overcommit (notwithstanding that Linux cannot provide perfectly accurate strict memory accounting), and I'd prefer not to use swap, but Linux VM maintainers have consistently stated that they've designed and

I'm not even sure the 20th century was an aberration. Yes, the 19th and 20th centuries saw outside influences (Opium Wars, WWII, Communism) triggering massive domestic changes, but those influences happened at the edges, geographically

That seems a little too cynical. It matters how a customer might use a chip, such as the type of cooling that would be expected in a typical system using that model, and that's informed by the advertised specifications. Base clocks a

In the case of io_uring, one user thread per core is not a bad rule of thumb given that the kernel side is using a pool of worker threads.
