    Having an objective score is quite difficult. Maybe it would be better to do a pairwise comparison and calculate ELO?

    I don’t think this is as simple as it seems. For example, we have our own CA and issue several mTLS certificates, with hundreds of them currently in use across our machines. We nee…

    The batteries in MWh range cost around 160 EUR/kWh all in. Including grid connection and BOP.

    I like the Rust being there. It is a reality check to keep the numbers in perspective. (C, C++ or something like that would work too)

    My guess would be they are running some dummy app like quote of the day or something and it records the screen at 1fps or so.

    OP should consider changing their alias.

    Yes. It is common on leetcode.

    I used to write actively on LinkedIn. Nothing big but still something. I couldn’t align with myself with the original post but I couldn’t tell why. This is aligned with my understa…

    I love your setup. The ingenuity of such solution is outstanding. I have so many questions but I'm afraid to ask.

    What surprises me the most is that there is no benchmarks table right at the top. Maybe the improvements are not to call home about?

    Yes. I’d rather read the prompt than this.

    They are almost the same batteries. Different form factor but same thing. They are rolled from the same lines.

    Python 3.13 has finally introduced free threading, which is a big deal. I initially thought we wouldn't be able to use this in production for ages since packages would need time to…

    I don’t know where the 800W is coming from. It is quite common to have 16A breakers on a circuit. That is 3,8kW. My regular apartment has 3x20A breakers and for example my inductio…

    I'm no electrical engineer but would that really be so much cheaper? A buck converted is essentially the same thing where the transformer is replaced by an inductor. You get rid of…

    I wouldn’t want to relay on random caffee’s router to do this for me. I would still end up running firewall more carefully on my end devices. Which for my iPhone I’m not even sure …

    This assumes that we reverse the reaction. That does not need to be the case. We can put it back into the ground. It can either stay where natgas or crude used to be or we can basi…

    In my, arguably limited experience compared to some other folks, completely agree. It feels lite the correct solution here is to treat it as another kind of backend. I always keep …

    I don’t think that is the case. Surface roughness and directional changes are big losses. For example a single valve on a high pressure line can have a bigger pressure drop than 2 …

    I add my +1 to this. I often come across this blog posts while working as a OR professional.
