effie commented on Linux Pipes Are Slow   qsantos.fr/2024/08/25/lin... · Posted by u/qsantos

The very thing that makes pipes useful is what also makes them slow. I don't think there is much we can do to fix that without breaking POSIX compatibility entirely.

Personally I think there's much worse ugliness in POSIX than pipes. For example, I've just spent the last couple of days debugging a number of bugs in a shell's job control code (`fg`, `bg`, `jobs`, etc).

But despite its warts, I'm still grateful we have something like POSIX to build against.

What possible bugs can there be in those? They are quite simple to use and work as expected.

That is way too hostile for a first contact. It would be much better, at first, to politely ask them to comply with the license. If they ignore you, or refuse, then think about escalating.

What is the difference between legitimately taking advantage of open-sourceness and plagiarism? Attribution? If so, try to contact them and ask them to put your name/link to each file derived from yours.

Because the EU is not a national government. It issues no passports. It has no citizens. It levies no taxes. It has no army. It's an organisation that coordinates sovereign states. Often it doesn't even set the law directly but establishes a framework that allows it to specify some requirements that national legislative bodies then have to turn into actual legislation. Frameworks for how to talk about things is very apropos for what the EU is and for how it came about.

I am not defending this state of affairs. Simply pointing out that it's a category error to compare it to national governments. I think it would be good if we had more of an EU state. It seemed to be heading there 25ish years ago. But the nation states do have little appetite to cede authority to the central institutions, so that's probably not on the table. And it's also undeniable that as a coordination mechanism the EU has been spectacularly successful. The fact that people treat it as a national government is proof of that.

I get you like the EU, but "spectacularly sucessful" isn't something many people would use. See covid response, and Ukraine war response. I would describe EU's mechanisms as moderately successful, i.e. somewhat better if states did everything on their own and bilaterally.

> The fact that people treat it as a national government is proof of that.

People with triste knowledge of how EU works do that. I do not think having most people in dark about how EU works is "spectacularly successful".

There have been a lot of comments on many Internet forums, during the last months, based on various benchmarks of engineering samples, that the gaming performance of these new models will be only marginally better than of the existing Zen 4 models and some times even lower than of those with 3D cache.

Only when the models of Zen 5 with big 3D cache will be launched it is expected that they will be noticeably faster for gaming.

When a 5.5 GHz 9700X matches or exceeds in single thread performance a 6.0 GHz 14900K, that is an almost 10% over the older competition and it certainly is 13%-18% over the corresponding model of the same clock frequency from AMD's previous generation.

There are many professional applications where the AVX-512 performance is decisive. There would have been much more, had Intel not prevented this by their market segmentation policies, which force most software developers to support only the weakest and most obsolete CPUs. I am myself interested in certain CAD/EDA engineering applications, where I expect a good speed-up from a 9950X, at a much lower price than for any previous solutions. This is a nice change at a time when most computing solutions increase in price, instead of decreasing, like in the old days.

Still, the non-improvement in default setting surprised people, e.g. see the embarrasing confession by PCWorld, they did not believe the performance increase is so minuscule and asked AMD if that is for real.

> it certainly is 13%-18% over the corresponding model of the same clock frequency from AMD's previous generation.

More like 10%. And you have to overclock for that. Overclocking has become a fool's errand, you can expect it to cause problems, crashes, etc. Granted, if crashes are rare, gamers may go for it.

> It's a flop for people who expect that after 20months, they'll get 13%-18% more.

If you have unrealistic expectations, everything, everywhere is always going to be a flop.

You're not getting 18% more IPC at 30% energy savings in a single generation. That kind of uplift hasn't been seen probably since Pentium 3 vs Pentium 4 era, or maybe Nehalem vs Core Duo.

Regardless, if you run the Zen 5 CPUs at the same TDPs as the 7000 series, you can still easily get 15-20% uplift. It's just that AMD has chosen conservative defaults for energy efficiency.

And purely for gaming, you should be waiting for X3D versions.

effie · 2 years ago
Gamer/enthusiast segment expects performance increase, not energy savings. CPU consumption is not even the greatest power hog in gaming PC.

Zen 3 brought 20% more performance at much better power consumption than Zen 2, and this set expectations. Zen 4 was a weaker improvement, and some people hoped that was one time thing, and maybe Zen 5 will get back to Zen 3 level improvements or better. But the improvement is even worse this time.

That's why in this consumer segment, 9700X is like Intel 11gen, a token increase in performance (and sometimes, decrease) as compared to previous gen, and thus a meh product. In other segments, like in desktops for work, or laptops, focus is different, and the same performance at lower consumption is a great new feature. So it's not all bad - it's just meh for gamers and enthusiasts.

Yes, you can overclock, and expect to either win the lottery, or maybe get problems like Intel has. If AMD did not clock these higher by default, there is a good reason for that, and it is not because of green political reasons. AMD has every incentive to clock as high as possible, to look and sell better. Most probably, the current batches of 4nm chips out of TSMC aren't rock-solid at higher clocks.

Re X3D, yes those should be better. But this is marketed as 9700X, not as 9700, so it's a flop. PCWorld was so surprised by the non-improvement that they postponed their review and checked with AMD if their poor bench results really are what AMD intended them to see.

Please explain how Russians are still able to do it? They even blew up their own pipeline to stop EU from buying their gas but somehow those Europeans find the way to still work arou d the embargo’s…

HIMARS it. Unbelievable the EU is still buying Russian gas.
effie · 2 years ago
Why? It's cheap, and it's beneficial to some European states/business, and Russians only get some small money for it from Europe. This trade does not seem to harm Ukraine efforts that much, the support given to Ukraine should overcompensate strongly. Ukrainians do not like Europe paying Russia, but they understand that just stopping gas/oil going from Russia to Europe won't help them much, and may antagonize parts of Europe.

Oh ok. So bells theorem is wrong and I have to cite scientific sources to convince some random person on the internet.

Look: i have a degree in physics, and I also don’t have time to argue with you. You don’t want to learn? Your loss.

You’re one of those people for whom “winning” is more important than the truth, I think.

You know what? You win. You’ve outlasted me. You’ve successfully learned nothing, and nobody will ever care about your statements about bells inequality because they’re laughably wrong and nobody will read this anyway. Victory is yours!

I didn't say that, and I think that statement is wrong.

> i have a degree in physics

Oh my. You lose credibility in an argument about physics when you fall back on authority, and even more, when that authority is supposed to be you.

> I also don’t have time to argue with you. You don’t want to learn? Your loss.

But if you don't have time to argue your point, why did you post it and defended it, and only pull this lack of time now? I would like to learn something from your posts, but so far, you regurgigated the usual incorrect/misleading claims about quantum theory and what the Bell theorem and related experiments imply. So then I thought it is you who may learn something new - please check the article I gave you above. If you do not want to take it from me, take it from people in academia who are better experts on this topic.

> You win. You’ve outlasted me. You’ve successfully learned nothing, and nobody will ever care about your statements about bells inequality because they’re laughably wrong and nobody will read this anyway. Victory is yours!

I disagree, because my aim was to learn or make you learn something I know, and so far I think I didn't succeed in any of those. So, please check the article in the link, if you have genuine interest in this topic.

Google is doing the same thing with youtube. Youtube was a place to get away from traditional media, cable tv, etc. That was the point of the "You" in youtube after all. But now, no matter what I search, it's mostly corporate/traditional media in the list. Youtube was a major part of the 'cut the cord' movement. Now youtube is rebranding itself as 'cable tv re-imagined'.

It's amazing how google and youtube did a complete 180 in just a few years. Google search and youtube are nothing like what it was 10 or 15 years ago.

effie · 2 years ago
I observe this as well, however, because Google wants to catch your attention and keep you for as long as possible, it is quite possible that this is also because of the past view history or terms you search. That is, if in the past, you let play lots of videos from traditional media, or search things traditional media like to talk about, then this may reinforce their appering in the search results.

If you watch videos on space flights and search related terms all the time, I expect you'll get related recommendations and links on less mainstream channels.
