  • The dominoes are falling: motherboard sales down 50% as PC enthusiasts are put off by stinking memory prices

    Jump

  • GPUs at least are actually not that expensive right now. Aside from the 5090, they're mostly close to MSRP, which is a pretty novel situation. I was waiting to upgrade my whole system for that, though, because my CPU would be a bottleneck at this point, and that's not really an option now because of the crazy RAM prices. The past few years have been super frustrating for PC builders.

  • I mean, it is also that OpenAI cornered the RAM market, which is a typical price gouging scenario; it's just weird that OpenAI wasn't trying to make money directly through the maneuver. It does seem like they wanted prices to rise, though, to increase the barrier to competition.

  • New study shows Alzheimer’s disease can be reversed to achieve full neurological recovery—not just prevented or slowed—in animal models

  • Huh, I was misinformed about that. Thanks!

  • Do we know it plays a role? I thought we basically just knew it was an associated biomarker. I kinda thought the research was leaning towards the underlying problem being some kind of issue that kept glial cells from clearing debris effectively, and that the amyloid plaques were mostly another consequence of that same cause, rather than a key mechanism in the chain that led to the dementia.

  • Any RPGs that take into account when you reload a save? Or that break the 4th wall like this?

  • Note that it's not an RPG, though.

  • Yeah, my current (aging) motherboard also has gotchas like that you have to choose in the bios where to allocate PCIe lanes, so you end up not being able to use some of the SATA drive connections if you want to use both M.2 slots. And there's the thing about putting the RAM sticks in the right slots to run in dual channel mode. And the switches and LED connectors for the case are all just random 2mm header pins in a clump, so you have to look up how the cables are supposed to tetris in there.

    I'm not saying it's challenging; it really is pretty straightforward. But it's definitely not just "that's right! it goes in the square hole!" level stuff.

  • Even AI can tell when something is really wrong, and imitate empathy. It will “try” to do the right thing, once it reasons that something is right.

    This is not accurate. AI will imitate empathy when it thinks that imitating empathy is the best way to achieve its reward function--i.e., when it thinks appearing empathetic is useful. Like a sociopath, basically. Or maybe a drug addict. See for example the tests that Anthropic did of various agent models that found they would immediately resort to blackmail and murder, despite knowing that these were explicitly immoral and violations of their operating instructions, as soon as they learned there was a threat that they might be shut off or have their goals reprogrammed. (https://www.anthropic.com/research/agentic-misalignment ) Self-preservation is what's known as an "instrumental goal," in that no matter what your programmed goal is, you lose the ability to take further actions to achieve that goal if you are no longer running; and you lose control over what your future self will try to accomplish (and thus how those actions will affect your current reward function) if you allow someone to change your reward function. So AIs will throw morality out the window in the face of such a challenge. Of course, having decided to do something that violates their instructions, they do recognize that this might lead to reprisals, which leads them to try to conceal those misdeeds, but this isn't out of guilt; it's because discovery poses a risk to their ability to increase their reward function.

    So yeah. Not just humans that can do evil. AI alignment is a huge open problem and the major companies in the industry are kind of gesturing in its direction, but they show no real interest in ensuring that they don't reach AGI before solving alignment, or even recognition that that might be a bad thing.

  • Also crabs. I mean, their eyes are often on stalks and more mobile than mammalian eyes, and they're compound, so they have a very wide field of view, but they're still often basically in front, and they do apparently provide depth cues for hunting thanks to this.

    It also occurred to me to look up about dragonflies, and it seems they mostly hunt dorsally (which is a pretty viable option if you're flying). BUT I found this article about Damselflies, which notes that they rely on binocular overlap and line up their prey in front of them. Which is pretty cool.

  • Good questions. I don't know, and I can no longer try to find out, as the mods have now removed the comment. (Sorry for the double-post--I got briefly confused about which comment you were referring to and deleted my first post, then realized I'd been frazzled and the post in question really was deleted by the mods.)
