I went a little crazy and setup my own wireguard VPN network, all the remote hosts connect to the VPN and the primary server connects to each of them and pushes backups. Because I use btrfs and lots of snapshots I use btrbk, annoying to setup but now my hourly snapshots get pushed everywhere, minimal bandwidth and it flawlessly has worked for years.
I do this except the offline copies are raspberry pis, they grab an update then turn their network card off and go black for about a month. Randomly they turn on the network card, pull a fresh copy and go black again. Safe from randomware and automatic.
I have a trailer (workshop) with solar power, batteries, a raspberry pi controlling everything and a cellular hot spot. It pumps all the solar, battery information and light controls over MQTT and home assistant over cellular. So yes its possible, what do you want to do?
My 16 year old Samsung TV would like to argue otherwise! It's a beast and 1080p is plenty good for me! But my Samsung kitchen? Holy crap it's all so terrible...
I host it on the host that runs the script and proxy it. I have one mission critial pi that is my uptime bot, pi hole and backup VPN if my elaborate server falls on its face. But you could easily use docker volumes too, and have the script push to that folder.
Similar, but more fancy, I have a bash script that runs every 15 minutes and ingests a config file. The config file has a super simple CSV format of every service I have. It checks that all the services are operational and generates an HTML file from it. If any services are down the HTML will show its down, otherwise its just a helpful link.
Older speakers like that use always on transformers, constantly wasting energy to keep the core energized. You're correct those cannot be made any more, they must use efficient switch mode supplies.
Not directly answering your question, but I'm an avid Gardner with 15 years of hobby experience and I stopped growing spinach because it attracted so many pests and I don't spray. I found varieties of kale with delicate leaves better because they grow faster, were much more bug tolerant and tasted as good or better.
If you have some outdoor space and interest, growing some greens for yourself is very easy if you get the right varsities.
I know way too much about the propagation of plasma in fluorescent lighting. When you first hit a fluorescent tube with high voltage you need some cosmic radiation to rip off the first barium ion off the cathode which causes a tiny little lightning strike of plasma that skitters across the inner surface of the tube. Once it makes its way across the length of the tube to the anode you now have a conductive path. This path then grows tremendously until it envelopes the whole cross section starting from the anode and works it's way back to the cathode until the whole tube is filled with wonderful plasma that makes light when it excites the phosphor coating.
+1 on this idea, going to toss in my recommendation for an AMD 5600g second hand. Its basically a laptop CPU with built in GPU that handles my jellyfin transcoding without issue and has a super low idle power rating if you pair it with a quality, small PSU.
I didn't down vote you but honestly interested in an adult conversation regarding your stance. If all I use is MS365 and I can use it in a web app with full 2FA how am I a security risk? I can access all the same things on my personal laptop, nothing is blocked, so how is Linux different?
