  • With a super lightweight laptop, 5w is achievable during light usage. I have one that draws that. It’s usable for Google Docs sort of stuff indefinitely on a 5w charger. It can also go down to ~2.2w with low screen brightness and very low load. It is absolutely terrible though, celeron 3855u. I got Minecraft Java to run at 60 fps though… But it was probably using 7-12w then.

    With a modern arm chip, you could get pretty great performance at that power draw. My phone (snapdragon 8 gen 3) in power saving mode can be like 5-10x faster at about 6 watts it seems like.



  • Makes sense, for naive, completely diffuse lighting (not reflective) the result is just the sum of base color * light visiblity * cos(angle between surface and light) for every light

    And then for light bounces just repeat that many times, but considering every surface as a light

    In the general case, for a more complicated material, the resulting brightness on a surface can be pretty much any arbitrary function of wavelength, the angle the light comes in, and the angle of the observer (called a BRDF). As long as it’s not putting out more light than it’s getting in, it’s probably possible. These functions can get especially complicated when there’s multiple thin layers, imagine a brushed metal surface with a layer of oxidization, a clear coating, some dirt, and some dust. Even for a single position on the surface, each of those reacts so differently to different input and output angles that no simple functions will represent the surface well. For CGI in films, they usually will layer many simpler BRDFs together, but that’s slow for games, which usually try to approximate surfaces in a single one.


  • Yes, it’s a common brand.

    In the United States, pudding means a sweet, milk-based dessert similar in consistency to egg-based custards, instant custards or a mousse, often commercially set using cornstarch, gelatin or similar coagulating agent. These puddings are known in some Commonwealth countries as custards (or curds) if they are egg-thickened, as blancmange if starch-thickened, and as jelly if gelatin-based. Pudding in America may also refer to other dishes such as bread pudding and rice pudding, although typically these names derive from their origin as British dishes.

  • Originally, the president did have basically no power. The whole federal government wasn’t supposed to do that much, and the executive branch by itself was supposed to do almost nothing compared to today. They didn’t even think there would be a standing army. States not being willing to put in strong reforms by themselves led to more executive agencies and executive branch influence over the country. (Which is all controlled by the President, since that made sense for the things that they thought in the 1790s the executive branch would be doing.)

    The whole system was made around an idea of who would do what, which has turned out to be completely different after 250 years. It’s not really surprising that it isn’t working very well.

    I don’t really know where I’m going with this. To even get a sane and effective Congress, we need voters to be aware of the real world, which seems like the largest hurdle right now. In the past, large and effective reforms have mostly been lead and advertised by the President, although it’s possible that with better voting systems and less presidential power parties would be able to cohere behind consistent and strong visions. Conservative think tanks seem to be able to do that currently, but they’re very quiet about it and I don’t know of a progressive equivalent.
