I think all groups engage in in group preference. If you look at businesses run by Indians in the US, they clearly favor hiring Indians, you see the same with other groups. Same with various East Asians, Jewish people etc.

It isn't just the dominate group, it is everyone.

So simplifying, if you have only 2 groups, one being 30% and the other 70% of the population, it would at first appear the 70% group has an advantage for finding jobs, but in reality they do not, as while they are favored at 70% of jobs, they are also competing against an equivalently larger group of people.

Anyway the implementation of racial preferences in college applications, and DEI has led to a system that systematical favors certain groups, and gaslighting that somehow this isn't the case.

I don't support Trump but liberals denying this reality, along with various other incredibly stupid woke positions, has led to the current situation, where we have a complete and utter imbecile running the country, because hey, at least he doesn't deny reality in regards DIE/social issues.

Trump is wrecking the US at the behest of Putin, directly or indirectly doesn't really matter.

Hence he didn't put tariffs on Russia.

It means like king/queen/emperor, you wouldn't use it for an elected official, so here it is more sarcastic because Trump is acting like he is an emperor.

Yes I found CPP AMP really interesting, but since it only ran on Windows..never used it for anything.

  1. who says it hasn't?
  2. most of the vul code is C, which is obviously much harder to harden, and the Rust Evangelism Strike Force loves to pretend that C++ is the same as C, so no matter the improvements to C++, they will just point at C.
  3. I think many simply didn't know about these hardening modes, MSVC has had this for 10-15 years, but I still encounter people who don't know about it..somehow.

Interesting, for all the winging about C or C++ this shows most of these apply to all languages, and the ones that relate to C or C++ are actually pretty easy to prevent in C++(less so in C) by enabling hardening modes and using smart pointers.

Oh that explains why the tariffs are focused on China.. Oh wait, that is what Biden did.

Trump? Yeah, no, he is just a moron, and prefers to tariff our allies, which means eventually we don't have allies, which makes your war against China abit more challenging, eh?

You don't really need to use sfinae anymore, concepts are cleaner and easier to follow, also this library appears to use concepts

What is the point of making JS go faster? It is already fast enough even on older computers for the stuff it is designed for, making crappy UI.

It is using c++ 26 features, so of course it looks slightly alien, nobody uses it yet.

Those thin soled shoes are hell for hiking, I did 1700 miles in a pair on the PCT, by 25-30 miles in a day my feed were screaming in pain. Had insanely thick callouses on my feet(it split on my heel and I could see at least 1/2 inch of nothing but skin).

Switched to sandals with much thicker sole at the 1700 mile mark, and after that I could do 45 miles per day with no pain.

If you judge them in person, I think redwood easily wins, and CA has two giant versions(coastal redwood and sequoia).

Also Douglass fir is nearly as large & long lived as redwood, tho less impressive in person.

I had hoped the GPU API would go away, and the entire thing would become fully programmable, but so far we just keep using these shitty APIs and horrible shader languages.

Personally I would like to use the same language I write the application in to write the rendering code(C++). Preferably with shared memory, not some separate memory system that takes forever to transfer anything too. Somelike along the lines of the new AMD 360 Max chips, but graphics written in explicit C++.

A few years ago I compared them, it was not a microbenchmark, but a real application. There were a few million(almost entirely uncontended) exclusive locks being taken on startup, SRWLock was consistently faster, though the difference was not large.

In some rare cases you can get an exclusive lock when you asked for a shared lock, most code won't care and will still work correctly, but sometimes people do weird shit that they probably should have used a different construct for, and run into this.

There is no reflection in this example, this is easily replicated in C++

SRWLock perf is slightly better than Window WaitOnAddress stuff, and works on older versions of windows.

That example looks easy enough to replicate in C++ with consteval + template, basically the same except a few minor syntax changes.

It just looks like C++ templates with a slightly different syntax ..
