Is open source microcode something that even Richard M. Stallman  would care about?As I see it, it like his microwave: if it’s not immediately obvious if the device has firmware at all, then it doesn’t matter if the answer is “yes, and the source code is proprietary”. http://www.linux-mag.com/id/255/ posted:I’m not so much concerned with what goes on in some sort of appliance where you can’t load software. If you can’t copy any software onto the thing, then in some sense it doesn’t matter whether you’re allowed to copy this particular program.

LeftistMuslimObama posted:Remember that server farms exist, people often own multiple personal computing devices, and businesses frequently have more computers than employees, and due to usage business computers often need new parts more often than personal devices. Windows XP sold a billion copies. There are a few factors working for ASUS here—ASUS sold motherboards for longer than Microsoft sold XP, Windows licenses are transferable in some cases, not all computers run Windows, it is not possible to pirate a physical product—but there’s no way they did five hundred times as much business. They’re not even the world’s only manufacturer of motherboards. Someone put too many zeroes in the number. e: They celebrated 500 million sales in 2015.. They Didn’t sell 69.93 motherboards for every man, woman, and child on the planet in two years. Someone copied that figure but forgot how numbers work.

It’s a reasonable tradeoff on the whole, but it’s a little (but only a little) like the FDIV bug: Sure, it probably won’t affect you, but you never know when you’ll run some code where it does matter. It’s tempting to pay the Intel tax and guarantee that can’t happen. No one has ever been fired for choosing Intel.

It’s no big deal when hundreds of millions of dollars of research equipment are doing the work of half of hundreds of millions of dollars of research equipment. No one is choosing between half‐speed AVX or erroneous FDIV. They can both be bad things.

Gwaihir posted:Is there a good reason for me to give a poo poo about having ECC ram on the box storing my linux ISOs? What is it protecting me against? If the result of a flipped bit in ram getting stored to disk is a flicker of a corrupted frame in a video file, it's not exactly something I think I'd worry about paying extra for, but I don't really know. Here’s an article where someone actually successfully tracks down a single bit error in some code. Yes, chances are good that the effected data is will never be written to disk and that if it is, it’s something that isn’t critical like a video file. But if bit flips in executable code, you’re in for a headache.

Truga posted:It's this. This isn't even a time constraint on certifying things. A random gamma ray (and there are a lot in space) hitting the big 386 chip doesn't really have much chances of displacing something important. A high energy neutron hitting something in your modern <30nm arch is going to wreck it hard. 386 and 486 are perfect for that use, just due to the sheer size of each element. That works for now, but for the future, will we keep the 486 foundries running, stockpile all the rad‐hard chips we could every possibly need, or rad‐harden newer tech? Like, instead of having one processor where a gamma ray won’t do much, have a handful running in lock‐step with a bunch more as hot spares. When one of them disagrees with the consensus, restore it to a known good state. If it continues to err, remove it from the pool and bring a hot spare online.

I mean, why would they not go with Intel’s convention? This is a foreseeable outcome of the failure to do so. I don’t care if AMD engineers think that this ordering scheme is more logical. When in Rome, do as the Romans do.

Beating x264 on “veryfast” is better than I expected for hardware encoding.quote:From this computer-generated rating with mainly the mse as criteria, you may come to the conclusion that NVENC is on par with x264 preset=veryfast (the default in OBS), or even a bit better, but unfortunately it isn't.

Watermelon Daiquiri posted:how would a qualitative measure of how close a compressed file compares to the lossless original not imply how good it is? I mean, i'm sure you could cheat it if theres like a repeating pixel pattern or something as the only difference, but for the most part it'd be accurate especially if you keep file size into account. It turns out that people are not computers. I mean, psychoacoustic/psychovisual weirdness is the basis of modern audio/video impression. If the human brain primarily cared about strict numerical deviation, we wouldn’t be using the H.264 codec at all.

Paul MaudDib posted:So yes, a computer actually can tell you whether it sounds good or not. At least, if your psychoacoustic model is a good one. No, they aren't perfect, yes, they usually are better than subjective reviewers. Ever read head-fi or some of the other "audiophile" forums to see what happens when you let subjective reviewers jerk themselves off? A numerical comparison will never be better than a good, blind comparison made by actual human beings because you’re attempting to discern is human opinion. As good as a computer model of a building might be, it will never more accurate than constructing the building and testing the real thing. More convenient, definitely, but not more accurate.

I would like to suggest that it is not actually that hard to label some clips “A”/“B” and ask some people which looks better. Computational testing is useful when you are developing an encoder, but when you are comparing a handful of existing options, that’s not an insurmountable volume to test on real live people.

The Iron Rose posted:While the marginal production cost might be pretty low, you still have to compensate for the billions and billions of dollars spent in research, so it's not as simple as Intel earning a few hundred dollars of profit for every CPU sold. Yes but the question was whether the marginal cost savings of a smaller die is worth the retooling. For that question, marginal cost and the cost of retooling are important. The development cost of the architecture is not.
