    There are many well documented cases of rapid evolution: a population of African elephants became 50% tuskless at birth in a single generation, urban fox anatomy diverged from rura…

    I'd have no idea how to find him. But I think it'd be a fruitless task anyway. I'm sure they'd have no memory of what, to them, was a moment as mundane as any other that day. I've …

    I think I have an observation that defies the info on that page. That page was written around the time that STEVE (an aurora related phenomenon) was first named. https://en.wikiped…

    For a few years I worked in the team that wrote software for an embedded audio DSP. The power draw to do something was normally more important than the speed. Eg when decoding MP3 …

    Those aren't the only resources. I could imagine XOR takes less energy because using it might activate less circuitry than SUB.

    > Code is formal, and going from C to assembly is deterministic. OK, this is the main thing. Going from C to assembly is not deterministic in a sense because different compilers ca…

    I wasn't comparing the two studies. I was just asking what the first sentence of the abstract of study 1 meant when it appears to be a false statement given study 2's result. Usual…

    The abstract begins, "Growing evidence supports early eating to control appetite and energy balance". What does that mean? My unskilled reading of it is that there is recent eviden…

    In the UK the wholesale price was about £80/MWh in 2025. The retail price was about £270/MWh + a standing charge. If you factor in the standing charge, an average user paid about £…

    We're seeing this galaxy as it was 280 million years after the Big Bang. But the universe didn't become transparent to photons until 100 million years after that ( https://en.wikip…

    Yep, I think it is. The point is there's almost no history of oral peptides, other than stomachs destroying them. FTA: "So to summarize the state of the art in oral peptide deliver…

    The British government continued to negotiate with Hitler after Kristallnacht (November 1938). They only stopped once he invaded Prague in March 1939.

    Seems like it is no longer considered to be anything to do with a meteorite impact. It's hard to find a good source. This is the best I found: https://en.wikipedia.org/wiki/List_of…

    That wouldn't make me happy. If the sharpie on the tape said it was bad, I'd still look at it, sniff it and probably eat it. Certain foods scare me though. eg there's a common clai…

    Edit: I think that was too strong. I don't have any real knowledge of this subject. The explanation in the article seemed reasonable to me. That is all.

    Fair point. It doesn't do the optimization if you ask to optimize for size '/Os' either.
