  • This isn’t really the same kind of bug. Those bugs made instructions emit the wrong answer, which is obviously really bad, and they’re really rare. The bugs in the article make instructions take different amounts of time depending on what else the CPU has done recently, which isn’t something anyone would notice except that by asking the kernel to do something and measuring the time to execute affected instructions, an attacker that only had usermode access could learn secrets that should only be available to the kernel.

    AGPL is a full-on FOSS licence with strong copyleft requirements, not a measly open-source licence like Apache, which could be pivoted to proprietary at a moment’s notice. We’re communicating through an AGPL-licensed system right now as it’s what Lemmy’s licensed as. If they were going for a corporate-friendly licence, AGPL is the last thing they’d choose as it forces you to share source code with even more people than the regular GPL does.

    Variations of this meme get posted every week, but I’ve never experienced it, despite having had tens of grub updates murder-suicide the Windows boot loader and grub itself across five or six different machines. Thankfully, it’s pretty easy to rebuild a Windows boot partition, but the frequency that I’m hit with this problem is one of the major reasons I avoid using Linux. Eventually I’m going to have to switch, but that’s driven mainly by Windows getting worse rather than any of the pain points I’ve had when trying to switch full time in the past having been fixed.


  • You don’t necessarily want to just ask for volunteers as that’s a great way to summon exactly the kind of people you don’t want to put in charge of online communities. The best way is usually to notice people who are already part of the community and consistently make positive contributions, then ask for their help. If none of those people want to, though, you’re stuck.





  • Even accounting for disasters, coal power puts more radionuclides into the environment into the environment than nuclear for the same amount of energy. If you dig lots of stuff up and spew it all into the air, the small amount of radioactive material that’s in coal and the rocks around it is much bigger than the tiny amounts of nuclear fuel a nuclear power plant gets through. If the only concern is radiation that persists on geological timescales, then swapping all coal for nuclear is an improvement. Other things that release surprising amounts of radiation include making things out of granite (it’s usually got uranium in) and importing bananas and Brazil nuts.

    If it’s changes on a geological timescale in general, then as fossil fuels form on a geological timescale (the clue’s in the name), digging them up is going to take unfathomable amounts of time to undo. It won’t even be as quick as the first time around, as most coal formed before ligninase evolved, so trees fell over and didn’t rot and usually became coal, buy they’re biodegradable now so need specific fossilisation-friendly conditions to become coal.


  • That problem isn’t unique to nuclear. It wouldn’t be newsworthy if a worn-out wind turbine blade was incinerated unsafely, and that’s something that happens routinely and is much more damaging than dumping this quantity (about a beer crate full) of depleted uranium. The reason we’re hearing about this incident is that the nuclear industry is held to a much higher standard than anything else in the energy sector. There are good reasons for that - the worst case scenario for a single fuckup is much worse - but a lot of it is just fear-mongering by fossil fuel companies who needed to lie to make something seem more dangerous than what they do, even before climate change was recognised.

    Nuclear is so much better than fossil fuels that even if we cut every corner and accepted a Chernobyl-scale indicent would happen a couple of times a year, it’d still be preferable over the gradual phase out of fossil fuels and resulting climate crisis we’re on track for.


  • Solar’s a little bit less killy than nuclear (people die when mining raw materials and from falling off rooftops when installing panels) and wind turbines are a little more dangerous than nuclear (mining raw materials, falls during installation/maintenance and people burning to death during maintenance), but hydroelectric power is much more dangerous than nuclear (mainly from drownings after dams burst). Until very recently, nuclear was the safest means of power generation by a wide margin, so if safety is the main concern, there should be a lot more of it.

    A big reason for this is that a single nuclear power plant can power a city despite having the same footprint as a small village worth of wind turbines or solar panels and running for decades off a wheelbarrow of fuel, so there’s much less for construction workers and miners to do and fewer opportunities for them to die. It only kills when there’s an accident bad enough to make international news and remain in the public consciousness for decades, and accidents that bad have only happened a handful of times.


  • The Olympics have allowed trans women to compete against cis women since the 90s, and yet there’s never been a trans medalist. If there was a genuine advantage to being trans in sport, at least one country in the past three decades would have loaded their team with trans women and cleaned house. However, taking enough hormones to make a masculine body into a feminine one after it’s already grown means you’ve got way less testosterone than a cis woman, so that counters out any initial advantage. Claiming otherwise is misinformation. Spreading misinformation to the detriment of trans people is transphobic.


  • As someone else said, installing things outside of Program Files is generally only necessary if they were made for XP or older, and the developers didn’t test on Vista or newer or read the bit of the Windows documentation that said not to write to an application’s installation directory because it might not work on future versions that was there since the early nineties. Regular Oblivion works fine in Program Files (although it makes it more of a pain to mod) and the Remaster was obviously made post-Vista.

    All that said, none of this is relevant because you’ve got the Windows App version, which uses a completely different system and works in a partial sandbox so doesn’t interact with the rest of the computer like a traditional program would.

    The scanner’s part of security, which is potentially shared between multiple airlines with multiple cabin bag weight limits, so it wouldn’t make sense as the place to weigh things. It only works if it’s done somewhere airline-specific, like check-in or boarding.
