    tired.

    inspired.

    also that contrast between the stark white window border and the gentle "solarized" terminal is pretty shocking, even on my 350 nits-rated laptop display set to 50% brightness

    @AnachronistJohn I assume that compilation indeed costs money for the extra electricity compared to just letting the computer idle, at least if it's a computer that knows how to enter some power-saving state when idle... The question is just: How much?

    If I owned a device that measures electricity consumption, maybe I could measure it, but unfortunately I don't.

    @vaporeon_ I like to know how long my machines will run on battery, plus colocation generally has power limits, so I’ve done lots of power measurements.

    A 12 core Ryzen 7900 with 128 gigs, an m.2 SSDs and a spinning rust hard drive takes about 48 watts idle. At 100% CPU utilization with active disk activity, it takes around 136 watts. Let’s just call the difference in power usage between idle and full use 90 watts for simplicity.

    Firefox 151.0.2 on this machine takes 1015.53 real to compile. This is Firefox itself, assuming all other dependencies are already installed.

    Chromium 149.0.7827.53 takes 10434.30 real, which is literally ten times longer to compile than Firefox. Again, all dependencies are already installed.

    Assuming 15¢ (United States) per kilowatthour, that’d be .282 hours at .09 kilowatts, or a little less than .4¢ to compile Firefox.

    For Chromium, that’d be almost 4¢.

    That’s not taking in to account storage, bandwidth, and time waiting for stuff to download - just the power used compared with the machine otherwise being idle.

    @vaporeon_ On the same machine, how long does it take to compile an entire OS? As long as Firefox? As long as Chromium? Somewhere in between?

    1581.34 real, to compile the whole toolchain that’s used to compile NetBSD 11, then the whole OS, including the kernel.

    Browsers really are big.
