I run Gentoo as my main distro, and have for a couple years now. It's a pretty stable rolling release (IMO more stable than Arch), and since you're already an advanced user, the experience should be pretty rewarding!
The wiki is great, and the installation handbook is top notch.
You get to control exactly what features each package is compiled with, so no bloat at all.
KDE 6 just landed too!
Shit, that's where my sex drive went. Can I have it back please?
Bah, real power users only need a magnet and a pin.
You don't need reproducible builds. You can get by if you trust whoever compiled it, like your distro's maintainers or the pidgin developers.
The risk of mis-ordering your layers is a security issue.
There are two ways to layer a VPN and tor:
In the first option, you gain little. Tor already encrypts your traffic, so your ISP can't see inside them. Technically, Tor over a VPN hides the fact that you're using Tor from your ISP, but Tor's snowflake does something similar if you need that.
In the second option, you're revealing your VPN account information, which could theoretically be associated back to you. Tor adds nothing over just a VPN in this case.
Don't mix tor plus VPN.
If you're using tor browser without tor for some reason, carry on.
Copyleft means: "if you modify the program and share it, you also have to include the source code for your modifications."
The owner of the copyright (usually the developers or their employer) can still change the license later.

FreeCAD is an option, but it's a bit of a mess. Does the job though!
