I know some people have gotten Nvidia stuff working, but from what I can tell, it’s still iffy. Maybe you were lucky.

I believe the Nvidia driver situation still sucks and maybe always will due to Nvidia incalcitrance. You could try pulling out that 3060 board. Next, what motherboard are you using? That might also have compatibility issues. Other than that, dual booting has sometimes been a pain, but if the system is coming up you’ve gotten past that. Your system is pretty powerful and should work well.

Structure and interpretation of computer programs (SICP) is a classic. It’s readable online or you can get a printed copy.

Get a SIP account with a VoIP provider and run a SIP client on your laptop. I’ve been using Linphone on Android and it works but isn’t great. It does say it has desktop versions. I haven’t looked into alternatives.

Phone OS’s usually won’t let you get at the voice stream, to prevent malware apps from tapping your conversations.

You could alternatively use some Bluetooth hack as someone said. It would help if you were more specific about what you wanted.

I use Debian on an old Thinkpad and (mostly) don’t have such issues. Installs and upgrades in particular work fine. I had probs with the wifi driver on my x220 but it works fine on the similar t520. Framework might be trying to do too much.

Doggone US carriers for shutting down the 3g network. I’d love to see the TSA goons try to install their crap in my old Maemo phone.

Can you keep the paper journal in a locked drawer? Will your homies seriously try to break in or pick the lock? Could you use a non-networked computer (old laptop) to encrypt the files, and lock that in a drawer?

You could but it’s no longer in vogue. Try Elixir instead.

Wikibooks might be ok for that.

For howto guides there is wikihow, though its license is noncommercial only iirc.

Wikibooks might also be suitable, as someone said. The other editors there are less insane about rule enforcement than wikipedia’s, anyway.

If you can say what your topic is, that could help.
