    It’s also running on a microcontroller with a few hundred kb of memory so even win16 or macOS classic would be a bit heavy.

    Unnecessary though productivity outpacing demand as far as I've understood it. In Marxism what they call "full communism" is envisioned to be the "final state of humanity" where pr…

    Economic systems of the 1800s doesn't really make sense in a space based, post scarcity society - economics is after all, the allocation of scarce resources. But I would argue that…

    Tesla is free to not sign a CBA, and union members are free to not serve Tesla. Swedish labor market is very free (as in unencumbered by laws and government intervention).

    Of course not. Having the ability to add or modify root CAs in browsers doesn’t imply a requirement to sign every webpage yourself either.

    That’s fine, assuming we pass laws mandating that signing keys can be controlled by end users. Otherwise we end up where no-one really owns their devices any more, every device wou…

    As someone who's two new arrivals recently turned two; it's by far the hardest thing I've done. I envy those who have one at a time. Having a startup fail around me was a piece of …

    Walking/Biking also allows me to instantly change my plans, even more so than driving does (try turning around instantly in a car). What do you mean "low large countries work"? The…

    Having spent quite a bit of time in the US, I've noticed that getting somewhere there takes about the same amount time as home (which happens to be Sweden, hence me clicking the li…

    True, many are indeed using ARM (in house designs are also more popular than you might think in deeply embedded SoCs), but a lot of companies would love to be able to throw out ARM…

    There's gazillions of embedded processor cores in every device you own. Your SSD, network card, phone, motherboard, router, TV, modem, car, fridge, you name it all have multiple pr…

    For reference, gas contains about 33kWh of energy per gallon, and if we assume you pump 20 gallons in 5 minutes when you fill up your car you have an effective energy transfer rate…

    A while ago, I spent a fair amount of time evaluating JIT frameworks including DynASM. The one I ended up using is something called Xbyak ( https://github.com/herumi/xbyak ) which …

    If you think the cost of the instructions to express copying is the main problem I'd call your mental model flawed. That is not the thing to worry about, when moving data the issue…

    German industry may indeed be in better shape, but that is inspite of German energy policies, not because of them. What you're really arguing for here is a poorer, less prosperous,…

    No, the correct answer is zero. The impact of Fukushima on someone living on the west cost of the US is negligible; as near to zero as makes no difference. There are many, many, ma…

    The number of non-acute deaths from Chernobyl is highly uncertain and difficult to estimate, even 30 years later. The range of estimate seem to more reflect the author's opinion on…

    The problem is that Germany, with its focus on wind and solar, is paying twice as much as for electricity compared to France - also a country with higher density in the middle of E…

    I'm not quite sure what you mean your first question, but I think heat pumps using air, ground or water as heat reservoirs would qualify. They are in common household use at least …

    Heating can be more than 100% efficient. Before you go "what, lol, no" - let me clarify. Obviously it can't be even 100% thermodynamically efficient, but a heat pump for example ca…

    Hah, I was just about to post more or less exactly the same code. :) It's funny, had the author tweaked the problem just slightly to try make C++ look good by saying that the progr…

    As an intermediate step, before starting with the SSE intrinsics I rewrote the code in a form that should have been reasonably suitable for an autovectorizer (an inner loop over a …
