About z2

"The surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself." -- Carl Sagan

    Given the angle of a panel should match its latitude and average sun angle, the panels might generate noticeably more by being pitched steeper at over 30 degrees. Eyeballing this, …

    Yeah, we're talking hundreds to thousands of mosquitoes per 1/10 of an acre, many or most of which are actually not actively flying, right? I can only see this working for dragonfl…

    Putting one's money where their mouth is in expressing that a company's stock appears overvalued is very low on my list of "things that exploit the proletariat."

    I don’t know how Apple divides computation between the GPU and the Neural Engine, but one major benefit, especially for real-time transcription on laptops, is the improved power an…

    So will the new ChatGPT (Codex) refuse to respond at all after the 5-hour quota or weekly quota is used up? It always felt that 5.5 on the website was a lot more generous than the …

    I don't think this makes any sense, what you argue would imply that the external historians would say that Japanese history starts in 1947 or that French history starts in 1958, bu…

    Same here, reserved a 48GB M5 Pro shortly after seeing the news, and now I see the same retailer raised the price by over $1000. If they honor the sale, then this will be the most …

    Will the coming wave of AI-assisted amateur traders make markets more efficient especially as they are more motivated to seek value in less liquid places, or will it be like sendin…

    Both have pretty enjoyable design language. The US signs follow colors, red for prohibition, white for rules, yellow for hazards, green for directional and blue for service. For Eu…

    In particular, I got a bunch of guesses correct because there's a pattern that several options are often related to each other, and either only one is different, (e.g., "Do good", …

    I'm confused on the choice of Ford as a champion. Yes SUVs and trucks dominate in the US and that's Ford's focus, but I'm not sure what they learned from the commercial failures th…

    I see parallels with the failed metric system transition: a voluntary shift with inconsistent policy, the impression that it's all just an elitist/foreign conspiracy, cultural/poli…

    I put Microsoft in the camp of operating system maker, as they are only able to run others' models. The "Give them three tries" meme can play out well for them yet!

    This all feels like a race where the model companies try to solve doing work locally in a way that doesn't suck, before the major operating systems companies figure out AI integrat…

    Sorry for the late reply, I regret the dramatic comparison to obvious physical harm. The argument is we tend to recognize industry-scale externalities after the fact, and that AI i…

    This is a late reply, but the point isn't aggregate demand. RAM price inflation directly harms people who have no stake in AI and made no choice to participate in this buildout. Th…

    This is textbook negative externalities, of the AI buildout on everyone who isn't using RAM/GPUs for AI, of the use of electricity and water on anyone who isn't using it for AI. Th…

    I remember both, the former is positive but suffers from short-term memory loss. the latter is always afraid of things, and also seems to never learn.
