Someone just removed many lifetimes of CO2 emissions with a couple of lines of code.
Shame that usage will just expand to fill the gap. Thanks late stage capitalism. Degrowth.
- Wasn't expecting this under a random unrelated post. A very welcome comment nonetheless.
  Never forget that the exponential boom of renewable energy tech the last 20 years has entirely served as additional energy, not as replacement of fossil fuels.
  
  Unexpected but entirely welcome.
  People do forget this all too often.
  Cheaper stuff, use more , value less.
  
  Source?
  In the EU at least this is demonstrably false. LNG has slightly risen since 2000 but other fossil fuels (namely coal) have gone way down. Total consumption has been steadily declining in the past few years and is down to 2004 levels. So overall our electricity is a whole shitload cleaner.
  The story is even starker for domestic heating. Gas and coal are vanishing since the mid-2000s.

  Edit: the other comment below mentioning this did not load initially..
  
  20 years ago there were 2000000000 fewer people in the world.
- Exactly, this is known as the Jevons paradox
  
  Thanks, got a new term today.
- I misread you as saying "Thanks late stage filesystem." 🤣

LKML and patch: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0fc810ae3ae110f9e2fcccce80fc8c8d62f97907
He cites his work as being a variant of a patch submitted by another developer, Josh Poimboeuf. It's a team effort folks :)
- Yeah, one man did hours of profiling and the other made the patch more elegant lol
  
  Kind of like the butcher who got his hands dirty cutting a steak and then a Michelin star chef cooking it for you.
  One got his hands bloody. The other made it delectable for you to eat.
  Which is more important to the process?

Damn, those are not rookie numbers!

ITT: people upset claiming Torvalds is political getting all political on a post about kernel improvements.
- I'm OOTL. Why are people upset with Torvalds?
  
  He followed legal advice from lawyers and removed some russians from being kernel maintainers to comply with sanctions.
  
  He took the authorization for a bunch of Russians from being able to keep working on the Linux stuff. I'm def not remembering everything and I'd suggest you searching any news about it, it's an interesting read

- Sometimes it is pleasant to defederate from an instance, especially if nothing of value is lost.
- It sucks that it overshadows the actual news.
  On the plus side, this post serves as a wonderful tool to clean up some garbage users/servers.
- Ingl, the amount of dislikes made me grunt a little
- More like a shitton of people with no knowledge about who actually worked on this patch erecting a personality cult around their new NATO hero.

The discussion on LKML was so civilised compared to this one.
I wonder what the phoronix one is like...

Great, now we're not going to catch the next zero day compression vulnerability. :)

What's the catch? Only on a specific price of hardware? Or is this an improvement on any hardware?

- I was expecting down votes, but the comment removed? It was a joke. Lol (see? A joke)
- The Mossad backdoor optimization finally got through.
  
  LMAO

Still not saying it's any good after he became geopolitical.
- Literally required to do it by law of sanctions
  
  He would only escape if he was a presidential candidate or a multi billionaire.
  Since he is neither and he works on US soil, then the law came after him. You would cave in, if in similar circumstances.
  
  I already explained my point about it. A lot of companies rebased themselves when political issues occured. The Linux Foundation could easily do that. It's just racism.
- Huh?
  
  Had a stroll through his profile and he's clearly only here to troll.
- You think open source project maintainers should move to different countries because of temporary sanctions? What if they have a wife with a job and kids in school? Or delicate Lego collections that are impossible to pack? Or a side-piece?
  Take issue with the sanctions if you want but don’t take issue with people who don’t want to move their family, LEGO collections, and side-pieces.
  
  There are hundreds of Linux developers, including companies like Red Hat, Intel, IBM, Google, and more. You want all these people to up and move to... where? Somewhere. Russia, or a Russian ally presumably but hell if i know. Anyway you want them all to move so a handful of people working for Russian weapons manufacturing companies can keep maintaining pieces of the Linux kernel?
  This is obviously a non-serious suggestion.
  
  Move physically? Of course not. If it's required to register the foundation, they could ask a maintainer from the country to register it. It's not the cleanest of schemes but it should work. Though if Linus lives in the US now, it can still cause issues because US law system has been proven to not work and they could easily arrest him illegally if they wanted to. However in this case it's the same as living in Russia. Both countries are terroristic.
- cool
- He is a finn, what do you expect from him? I fully support his position
  
  Really sticking it to those... friendly Russian kernel maintainers. Really doing your part for your individual Two Minutes Hate.
  So presumably, as a consistent person that is outrages by invasions and death, you call for the expulsion of all Americans and Usraelis, right?
  
  He is a finn, what do you expect from him?
  Continued use of the swastika in his military and a stubborn refusal to acknowledge how many Soviets the Finns starved to death in Leningrad while working with the Third Reich, presumably.
  
  Ok western chauvinist. Why doesn’t he ban the genocidal Israelis? It’s because he is full of shit and a racist
  
  His position is that he's an asshole who won't stand up to the US lol
  
  not to be a bigoted piece of shit? i guess we can't expect that from either of you worthless hounds.
  if he wasn't a complete hypocrite he'd ban people from the u.s. and israel as well.
  
  come on now, not all Finns are fascist dipshits, the Punakaarti were great
  
  Would you support him banning AmeriKKKan and Isn'treali developers too, given that their countries' war crimes are far grander in scale, horror, and devastation than Russia's?
  
  So you're a russophobe as well?
  
  Well, when you put it like that, I expect him to join the Israeli death squads "out of pragmatism"
- alright, chill
- This has to be a record for the most downvoted comment on Lemmy, holy moly. This is a huge absolute margin even for reddit.
  
  Well I am the most controversial Lemmy user. That was expected after getting a lot of upvotes.
