  • In addition to “format shifting,” which is a well-recognized use case, and game preservation, which is a huge and under-recognized public interest in emulator development, emulators are also used for the development of homebrew software. E.g., there’s a port of Moonlight for the Switch, which lets you play Steam games streamed from a PC using your Switch, letting it serve many of the purposes of a Steam Deck. That’s huge! It would be way less practical to develop this kind of software if you could only test on real hardware. Testing on real hardware is also essential, of course, but testing on an emulator is vastly faster for rapid iteration.






  • You know that the other two words also exist though, right? Like, you can effect change in an organization, and there can be something strange in the affect of a psychopath. So there’s a verb “to effect” and a noun “affect” (although here the pronunciation is different–the accent is on the first syllable). It’s true that the most common usages follow the rules you’re laying out, but it genuinely is an oversimplification.




  • Gluten kicks ass. It’s easily the best fake meat base. I remember in college cooking a meal for my roommates and them saying afterwards “wait, aren’t you vegetarian? did you cook this just for us and not eat any?” and having to explain that no, that wasn’t beef, it was wheat gluten and mushrooms and miso. They were dubious, saying, “well, to me this is just really tender beef.”

    So yeah. I’m also disappointed that gluten has gotten such a bad rap. I’m waiting for this knowledge to trickle back into the convenience foods sector so I can buy this stuff and not have to make it by hand every time, and it seems like I’ll be waiting a long time.



  • Attention is a kind of surplus mental capacity that we have, which isn’t specialized, but can instead be directed to tasks as needed. Ironically, we also use the term for the dedicated mental system which directs this extra capacity, which makes talking about it a bit more complicated.

    Most of the stuff we do, our brains just kinda handle for us. Walking is usually like that; it’s an incredibly complex feat of dynamic balance, movement planning, and adaptation to changes in the environment, but it rarely takes any conscious effort on our part. Conscious effort is directed attention.






  • It sounds to me like it’s pretty similar to how home oxygen concentrators work, but with an MOF instead of a zeolite, and driving out the adsorbed material via increased temperature rather than decreased pressure. MOFs are pretty comparable to zeolite in cost, and both can be used as molecular sieves, as in this case. Maybe you can find a video on oxygen concentrators that would help you understand it?

    One difference here is that in the oxygen concentrator, the output product is the air, but with the nitrogen sequestered out; here, the output product is the water sequestered from the air. But this leads me to think that maybe this tech could also actually be used for air dehumidification, which could drive down the energy use of air conditioners. That could be another big win, since air conditioning is a major use of fossil fuel energy and contributes significantly to climate change, which is part of what’s driving the drinking water shortages in the first place.
