  • Maybe not a service in the typical sense, but setting up your router+server to route your home network traffic through a VPN is a fun project.

    My router (MikroTik) supports WireGuard, so I can use it with Mullvad for the whole house—but wg is demanding and it’s a slow router, so while it can NAT at ~1Gbps, it can’t do WireGuard at more than ~90Mbps. So, I set up WireGuard/Mullvad on a little SBC with a fast processor, and have my router use that instead. Using policy based routing and/or mangling, I can have different VLANs/subnets/individual hosts selectively routed through the VPN.

    It’s a fun exercise, not sure I implemented it in a smart way, but it works :)









  • I do something similar — I have a raspberry pi and a HD, with daily rsync and snapshots (monthly retained indefinitely, weekly retained for a month, daily retained for a week). It’s at family’s house, connected to my home via WireGuard via a VPS. Tailscale (or anything really) would also work here.

    It’s a great setup! Just have some watchdog reboot if it can’t talk to home (a simple cronjob with ping -c1 home.lan || reboot or similar).

    Even our “slow” 35Mbps upload speed is way more than enough for incremental rsyncs of my Immich library. The initial sync was done in person, though.

    Linux distros can still do…questionable things. In grad school I tried Arch for a bit, and I once was late to a video call because I had updated my kernel but did not reboot. Arch decided that because there was a new kernel installed, I didn’t need the modules for the old — but currently running! — kernel, so it removed them. So when I plugged in a webcam, the webcam module was nowhere to be found.

    But yeah…somehow, still not as bad as Windows updates.


  • Our Internet went out for a few hours today, so naturally my smart switches, lights, cameras, motion sensors, door sensors, and power monitoring… continued to work as of nothing was wrong.

    Home Assistant is great, and using local-only devices is awesome. If my smart home stops working it’s my own fault, not some 3rd party.



  • Aluminum foil is very common in physics labs. And a main use for it is “baking”! To get ultra high vacuum (UHV)* you generally need to “bake out” your chamber while you pump down. Foil is used same as with baking food — keep the heat in and evenly distributed on the chamber.

    Sadly, it’s usually not food grade aluminum foil, as that can contain oils, and oils and vacuum are generally a big no-no.

    *Just how good is UHV? Roughly: I live in San Francisco, which is ~7 miles by ~7 miles (~11km). Imagine you raise that by another 7 miles to make a cube. Now, evacuate every last molecule of gas out of it. Now take a family sedan’s trunk, fill it with 1 atmosphere of gas, and release that into the 7 mile cube. That’s roughly UHV pressure.
