While I kinda sorta need my 3d printer more than my 2d printer, it's an absolute nightmare in a way that my 2d printer isn't, and it's caused entirely by the dogshit proprietary software I have to use in order to print things.

We need on disk encryption, and we need to be able boot from an encrypted disk. So we need encryption for that.

We need network filesystems, and we need the traffic over the network to be encrypted. So we need encryption.

IPsec, for better or for worse, is authenticated and partially encrypted at the transport layer, so if we want a linux machine to speak IPsec, we need encryption.

Fixing/changing this would require a huge restructuring of the kernel; it would basically require switching to a microkernel. Given the fact that nobody's ever written a microkernel that doesn't completely suck ass, I don't know that it would be worth the effort.

Now everyone is a troll/bot by default unless proven otherwise.

The jury was me, (white) nine other white people, and two brown people. Me and the brown people thought the cop was obviously lying, and was therefore not guilty. The nine other people thought he was guilty.

Like the cop was obviously fucking lying.

After three days of deliberation we declared a hung jury.

I was speaking with the prosecutor afterwards and he mentioned they were going for the felony version of the crime instead of the misdemeanor (he was obviously guilty of the misdemeanor, the felony depended on the element the cop was lying about) because the dude was a bad dude and they needed to get him.

I looked him up when I got home. (I didn't look him up during the trial, they expressly forbid you from doing that) He had done something bad and went to prison for four years. He did his time and got out. They were still trying to throw the book at him for bullshit.

I looked him up recently. He was never convicted of anything ever again, but died in jail two years after we declared a hung jury. Prosecutor got what he wanted in the end, I suppose.

Obviously you can't have oxygen in welding gas; it would oxidize the shit out of everything.

A little bit of oxygen in party balloon gas is beneficial. Some kid will breathe it, and when they do, you didn't want them to asphyxiate themselves.

Doing the same work sticking strictly to vectors and matrices tends to either not work at all or be bulletproof.

The other thing is that trig tends to build complexity very quickly. It's fine if you're doing a single rotation and a single translation, but once you start composing nested transformations it all goes to shit.

Or maybe you're substantially better at trig than I am. I've only been doing trig for 30 years, so I still have a lot to learn before I stop making the same sophomore mistakes.

Which is another reason the Bible should be banned from being accessed by minors. If a child needs an abortion, they should consult a medical professional. They should not read about how to perform an abortion in an app on their phone and attempt to perform the procedure themselves.

They are not a covered application store, but they are an operating system provider, so the law does apply to them.

I have memories from like 20 years ago that even when I had plenty of RAM, and plenty of it was free, I would get random OOM killer events relatively regularly. Adding just a tiny bit of swap made that stop happening.

I'm like 90% sure at this point it's just a stupid superstition I carry. But I'm not gonna stop doing it even though it is stupid.

AVX512 has 2048 bytes of named registers; AVX2 has 512 bytes. AVX512 uses out of band registers for masking, AVX2 uses in band mask registers. AVX512 has better options for swizzling values around. All (almost all?) AVX512 instructions have masked variants, allowing you to combine an operation and a subsequent mask operation into a single operation.

Often times I'll write the AVX512 version first, and go to write the AVX2 version, and a lot of the special sauce that made the AVX512 version good doesn't work in AVX2 and it's real awkward to get the same thing done.

"A $30 million mess-up" can look like (at least) two things. It can be $30 million was spent on a project that earned $0 revenue and was ultimately canceled, or it can look like $x was spent on a project to win a $30 million contract but a competitor won the contract instead.

It's my understanding that this is the case. I could be wrong; I hope to be.

Functionally, they're no different than bus lanes or a wide shoulder. Humans drive on them all the time, because there's no traffic on them and they can get to where they're going faster. They shouldn't, it's illegal, and they can get ticketed for it, but they do it anyway. If you load up google street view in Phoenix/Tempe/Gilbert you can see a few people driving on them.
