A reminder that “cashback” credit cards are paid for by big fees on transactions which the store pays, forcing them to raise prices. It’s literally anticompetitive

Do you think a device with regulation circuits is more likely to be overloaded and start fires…?

The infinitely easier solution is to let the car charger know how much power is available to draw.

You could do something clever with UV light possibly, but still. There’s going to be plenty of traces of crap on them even if all bacteria is dead

I remember this lol
Tldr neural network models are incredibly weird. My best guess is that the combination of common recurring structure with variations based on common rules (joke threads and all) helps the model derive some intuition about how to handle variations of things.
Also reminds me of an even earlier neutral network which got better at playing specific games after being trained on large amounts of text completely unrelated to the game, like encyclopedias or whatever.
- Comment on An alien who sees in the radio part of the light spectrum would probably be blinded by all our wireless communications 2 weeks ago:
Massive singular radio telescopes are used to pick up individual signals from one direction, and can’t do imaging alone.
Sure you can pick up long wave radio with smaller antennas, but not without trade-offs. They often need long coils, and to make up the remaining difference you need to very precisely control electric resonance, and you lose efficiency (you pick up less energy from the radio waves). You definitely can’t do imaging with just one.
Just look at how big NFC and Qi coils are, they can’t practically be made smaller at those wavelengths, or else you lose too much energy!
Massive radio telescope arrays spanning the globe uses the massive distance to create a tiny amount of angular resolution, just enough that with months of processing you can image a black hole a few light years away with some thousands of pixels. Compare to how your phone can run deblur algorithms on a fraction of the power over far more pixels, because the angular resolution makes such a huge difference (blur radius is infinitely smaller)

- Comment on New fuel cell could enable electric aviation 3 weeks ago:
Not sure it’s enough.
Airplane engines are about 35% efficient. Maybe you can push it upwards 50% with state of the art designs.
Fuel cells hits about 60-70%, state of the art can maybe hit 85% (and the electric engines can be efficient enough to be part of the error margin in this equation). Best case you’re halving wasted energy. That means you need AT LEAST half the energy density, or else you’re carrying more fuel mass for the same flight. Might be tolerable if it is at least cheaper, but you’re also adding stress and wear as you do.

They’re probably building off Windows RT (the locked down variant designed for ARM tablets).
If they were smart they’d imitate some of how SteamOS runs games in a modified WinRT environment - TLDR do NOT start up the entire Win32 runtime and desktop environment by default, don’t run stuff like printer services and whatnot, just run a simplified sandbox and window manager with just the APIs needed to run the games similar to Proton. Then let the user switch to desktop mode as needed, but don’t run it when gaming.
