Yes, you can still dual boot. I would recommend using two drives since it will make things easier. You can even use secure boot and bitlocker if you want to.

It’s a WebDAV server, so it’s more like FTP than Syncthing.

For email, you just pay for a host that will let you use your own domain. It’s usually a lot cheaper than getting a static IP and you can easily switch hosts while keeping your email address.

It’s not really even worth attempting to self host your own outbound email these days. It’s a lot of work getting the big email providers to accept your email and if someone has ever sent spam from your IP address, you are pretty much screwed.

I’ve been using KeePassXC. I use Syncthing to keep the database synchronized between computers.

All of my PCs are malware free.

You can enable file versioning so deleted files will be kept for a set amount of time.

It’s a switch, there shouldn’t be anything to go obsolete.

I’ve had a couple of computers with Nvidia cards and all I ever had to do was install the driver from the package manager and reboot. I always had screen tearing issues with them, but that was with cards from 2011 & 2013. I would hope that they’ve fixed that by now.

The only thing they are good at doing is producing loads of RFI and pissing off every ham radio operator in the area.

It only requires an outbound connection, which is needed if you’re stuck on CGNAT. It also provides DDoS protection and hides your IP address. It comes with the huge downside of using Cloudflare though.

Be sure to keep everything up to date too. Even openssh has had multiple vulnerabilities just this year.

There is OpenRazer for configuring Razer mice and keyboards.

SponsorBlock gets rid of most of the ads that the uploaders put in their videos.

I’ve got one of the older Reolink IP cameras and the video freezes for about 10 seconds every time it switches between color and nightvision. They never even released a firmware update for it. I wouldn’t trust them for anything important.

Did du give any permission errors? It can’t count the size of directories that it doesn’t have permission to access.

It will probably keep working fine for years. Eventually some dependency will become incompatible and it will no longer build though.

All a kensington lock does is cause a bit of damage so a potential buyer can tell that the equipment was stolen.

A thief will likely want to steal or destroy the DVR, so make sure it’s well hidden or locked inside a proper safe.

Look for a Dahua or Hikvision DVR and cameras. Put the DVR (and cameras if they are IP) on its own isolated subnet that doesn’t have any internet access. Use a VPN to access it remotely.

Don’t buy them from amazon, buy from one of their authorized distributors. I learned that the hard way when I ended up with a grey market camera with no warranty or firmware updates.

WiFi cameras are much easier to jam if someone wants to break in without being recorded. Don’t use them if you can run a cable.

Any printer that supports Mopria or AirPrint will work on Linux without installing any drivers.

I prefer using older Brother laser printers that don’t have any chips in the toner cartridges. I have an HL-4150CDN and a DCP-7065DN.

I’ve had torrents run for months. Usually with just one seeder that only connects periodically.
