  • At this point, they no longer obey the laws of classical physics, and the resulting quantum phenomena — known as relativistic effects…

    This is…not how I would word things. Atomic physics is usually not in a classical (Newtonian) regime, and a quantum treatment is standard.

    Adding relativistic effects to the quantum treatment is also standard, but many aspects of e.g. the hydrogen atom are reasonably well described without relativistic effects, though of course relativistic effects do matter.

    Nitpicking aside, neat stuff!







  • I’ve been pleased with it. Family is very relaxed about projects like this, but yeah it’s low power draw. I don’t think I have anything special set up but the right thing to do for power would be to spin down drive when not in use, as power is dominated by the spinning rust.

    Uptime is great. Only hiccups are that it can choke when compiling the ZFS kernel modules, triggered on kernel updates. It’s an rpi 3/1GB RAM (I keep failing at forcing dkms to use only 1 thread, which would probably fix these hiccups 🤷).

    That said, it is managed by me, so sometimes errors go unnoticed. I had recent issues where I missed a week of rsync because I switched from pihole to technitium on my home server and forgot to point the remote rpi there. This would all have been fixed with proper cron email setup…I’m clearly not a professional :)
