  • You are not joking. Comparing a $2000 Purism Liberty with eg. a $200 HMD Fusion. The Fusion has somewhat better screen and battery; much better processor and camera. More RAM, the option of more storage, has NFC. It’s also designed to be easy-to-maintain, but is somewhat thinner and lighter despite having a larger screen area. Are ‘made in USA’ and ‘open-source drivers’ worth paying 10x as much for a noticeably worse phone? (It’s not really ‘made in USA’ either - it’s a mix of US, Chinese and Indian parts assembled in the USA.)

    I think that the people who believe a US-made iPhone will also cost $2k are kidding themselves - economy of scale and all that, but it must be substantially more.



  • You’ve got that a bit backwards. Integrated memory on a desktop computer is more “partitioned” than shared - there’s a chunk for the CPU and a chunk for the GPU, and it’s usually quite slow memory by the standards of graphics cards. The integrated memory on a console is completely shared, and very fast. The GPU works at its full speed, and the CPU is able to do a couple of things that are impossible to do with good performance on a desktop computer:

    • load and manipulate models which are then directly accessible by the GPU. When loading models, there’s no need to read them from disk into the CPU memory and then copy them onto the GPU - they’re just loaded and accessible.
    • manipulate the frame buffer using the CPU. Often used for tone mapping and things like that, and a nightmare for emulator writers. Something like RPCS3 emulating Dark Souls has to turn this off; a real PS3 can just read and adjust the output using the CPU with no frame hit, but a desktop would need to copy the frame from the GPU to main memory, adjust it, and copy it back, which would kill performance.


  • Money is an emotional thing. Do I believe that this coin / bit of paper / number on a website is something that I can exchange for goods and services? If not enough people believe that, that currency will collapse.

    Mind you, not using money is inefficient at scale. Sending the bag of potatoes that I’ve grown in my garden this month to my internet provider for continued shitposting privileges only goes so far.


  • It’s one of those materials that has an almost complete list of superb properties, with one overwhelming downside. It’s cheap, abundantly available, completely fireproof and can be woven into fireproof cloth, adds enormous structural strength to concrete in small quantities, very resistant to a wide range of chemical attacks. It’s just that the dust causes horrific cancers. See also CFCs, leaded petrol, etc, which have the same ‘very cheap, superb in their intended use, but the negative outweighs all positives’.

    One of the ‘niche industrial applications’ was the production of pump gaskets in high-temperature scenarios, especially when pumping corrosive liquids. We’ve a range of superalloys that are ‘suitable’ for these applications - something like inconel is an absolute bastard to form into shapes, but once you’ve done so it lasts a long time. But you still need something with similar properties when screwing the bits together. For a long time, there was no suitable synthetic replacement for asbestos in that kind of usage.

    If you know that the asbestos is there, have suitable PPE and procedures, then IMHO it’s far from the worst industrial material to work with. It’s pretty inert, doesn’t catch fire or explode, and isn’t one of the many exciting chemicals where a single droplet on your skin would be sufficient to kill you. What is inappropriate is using it as a general-purpose building material, which is how it was used for so long, and where it was able to cause so much suffering for so many people.


  • If I believed that they were sincerely interested in trying to improve their product, then that would make sense. You can only improve yourself if you understand how your failings affect others.

    I suspect however that Saltman will use it to come up with some superficial bullshit about how their new 6.x model now has a 90% reduction in addiction rates; you can’t measure anything, it’s more about the feel, and that’s why it costs twice as much as any other model.


  • AI does give itself away over “longer” posts, and if the tool makes about an equal number of false positives to false negatives then it should even itself out in the long run. (I’d have liked more than 9K “tests” for it to average out, but even so.) If they had the edit history for the post, which they didn’t, then it’s more obvious. AI will either copy-paste the whole thing in in one go, or will generate a word at a time at a fairly constant rate. Humans will stop and think, go back and edit things, all of that.

    I was asked to do some job interviews recently; the tech test had such an “animated playback”, and the difference between a human doing it legitimately and someone using AI to copy-paste the answer was surprisingly obvious. The tech test questions were nothing to do with the job role at hand and were causing us to select for the wrong candidates completely, but that’s more a problem with our HR being blindly in love with AI and “technical solutions to human problems”.

    “Absolute certainty” is impossible, but balance of probabilities will do if you’re just wanting an estimate like they have here.
