I am not the most experienced by any means, but wouldn't it be better to run it with a ";" in the spot off all of the "&" so that way if one of the commands fail it doesn't stop mid script?
The two most important things that most people don't think about enough is making sure you get the right width of boot, and get a pair of quality insoles(they are just as if not more important than the boot they go in). I hated all the boots I wore until I got some superfeet insoles. As far as boot brands go I can back thorogoods as my goto.
I prefer mullvad because it has the option to pay with monero. It also seems more trustworthy than proton because they don't sell out users (that we know of), or make false claims
If all machine operators vanished anything mass produced would stop getting made.
They are a little pricey, I'll give you that. Just out of curiosity why shouldn't domains be private?
I use them for email aliases via adyy, and self hosting things like jellyfin and nextcloud. I don't really "need" the privacy, but I still like to have it if I can.
Njal.la is where I have all of my domains. You don't have to give any info, you can access it through tor through a .onion domain, and you can pay with monero.
Polymaker pla pro is a great pla. I have printed plenty of functional things with it and they all hold up really well. If you really need something more durable nylon 6 would be a good option to look at.
