  • 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 :)







  • Or, malicious compliance by someone with a moral compass. Best is to somehow leak documents wholesale. But if that’s not possible, I think the next best way to all but guarantee that the information gets out is to do a lousy job censoring, and let “The Internet” do the rest. It also makes the administration look even more stupid, especially in the eyes of technically minded folks.

    But yeah, not the best and brightest, that’s certainly a possibility.




  • +1 for ThirdReality. They’re a little pricey but I’ve generally had good luck with them.

    I’ve also had pretty good luck with cheap Matter-over-wifi bulbs. Pairing them can be a little finicky and needs to go through an Android or iOS process, but after pairing you can block Internet access for them and they work great local-only.

    There’s a bug in some wifi matter bulbs where they crash, especially when going from off to a desired brightness/color state (as in, “light on” works but “light to 50%, 3000K” will crash the bulb).




  • Lots of local-only options out there for security cameras. Doorbell cameras may be a little harder to find, but it looks like they exist.

    I have a few Amcrest PoE bullet cameras, and they work great local-only. They’re on a separate VLAN, only my server can talk to them, and I have had zero problems with them. They even support NTP, which my router provides, so the clocks stay synced with no intervention. I’m running them with Frigate.



  • VNC? You have your choice of servers, and clients are ubiquitous.

    A big gotcha is that you need to be careful with encryption/security, as in classic UNIX style VNC does one thing (remote desktops). It’s easy to forward over ssh though.

    You can also use VNC to share, which is not what you want; this depends on the type of server/settings. But you can definitely create a new virtual X11 session and access it remotely.
