My Futro S740 with an J4105 CPU consumes up to 14 Watts according to this article. It is faster than a rpi 4b plus i bought it refurbished for 40€. I think a system with an I5 6500t will need even more power under load.
Since your other question is already answered:
think leaving it as it is (unencrypted, no domain name, only accessible through IP) will be problematic.
Yes, that’s no biggy since it is on your local network only. But be aware that everyone that has access to your network could potentionally capture all the files you’re transfering and your nextcloud credentials as well. Other than that, your communication with nc will be encrypted on the wifi layer.
I’m using mailcow which comes with sogo groupware which works nice with davx⁵ on android, calendar, mail (with fair email app), tasks (with tasks.org app) and contacs.
I would argue that rsync is better suited to clone your file system when using linux. Just prepare the partitions (plus point: you can alter partition sizes and reorganise like having a new partition (or even device) for your /home or whatever) and mount them, then
sudo rsync -ahPHAXx --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found} / /mnt
Then fix your fstab and reinstall your boot loader. Way faster than dd and can be done on a running system.
Repos you might want to (git) checkout:
I’m using a SSH tunnel to connect a port on my vps to a port on my home server. I have rhevssl certificates both on the vps and the home server (I trust the vps provider), but I’m pretty sure (correct me if I’m wrong!) that this would work with the certificates only on the home server. Could the vps provider do a mitm then? I’m not sure, the packets go in one port and are directly forwarded to my home server.
Can the vps provider get their own certificates? That’s a good question. I guess you could check the certificate when connecting to prevent tampering. Datetime of issue alone should be enough since vps providers can’t fake that. Unless you don’t trust CAs either :)
Quantum computing is mostly a hoax. At least how it is presented to investors and the public. Quantum Computers will maybe be capable of solving a very small set of problems much more efficiently than regular computers, most of these problems aren’t of any parctical importance. It is a massive (financial) bubble that is going to burst soon.
You can basically connect any local port to any remote port normal or reversed. Reversed is -R, normal with -L. In this setting, correct me if im worng, you want to connect the open port on the airplane to one already prepared on a vps which allows you to do what you want e.g. proxy websites.
