OK, and Russia caused the pogroms and a genocidal famine in Ukraine. It's not a good idea to learn your country's history in an overly rosy way. In fact, being kind to nationalists may have caused the present war. Russians should

There were 8 years of diplomacy. There was maybe 1 year of intense diplomacy before the invasion on the 24th of February? Don't listen to Russian disinformation, it'll make you stupider.

Regarding religion, I've heard that the Talmud is a popular book in South Korea. I'm surprised by this. Is it appreciated for being analytical? For its tradition and lore? I'm Jewish, so I'm really curious about this. [e

If "programs ought to do one thing and do it well", then why aren't they just library functions in a scripting language? Scripting languages can probably do the same things (if given minor syntax improvements, see Xonsh) in o

That doesn't work. It's complex symmetric, but not real symmetric or Hermitian, so you can't use the spectral theorem. This statement here: It acts on R^N by independently scaling the coordinates of an orthogonal basis

Apologies, but you're going to have to provide evidence for these accusations. The alternative is that anybody can come out of nowhere and call another person awful. I understand this might be difficult.

As inflammatory as it is, my experience with Ubuntu (non-LTS) was the biannual death march. An upgrade broke my system. I never had any such experience with Win or Mac, so it was a Linux-specific problem. I suppose I could've used the

And when the mining stops, all its value vanishes. Value stored on jelly. Bitcoin has a runaway implosion mechanism built in, and no floor on its price except 0.

Never used them, but don't they have memory usage in proportion to the string being parsed? Regexes, LL and LR don't have this shortcoming. This should surely constrain their applications.

Is this in answer to my last question? Because I know how RPython works. The question is: Given that meta-tracing is about extending a JIT from a host language to a guest language, could you not then extend the JIT from the guest language t
