XDA ☛ How to change password on Ubuntu Linux
Ubuntu Linux isn't the most popular desktop operating system out there, but there are a lot of valid reasons as to why a large crowd of people prefers it over macOS or Windows. It's free and open source, offers plenty of distributions with different features and interfaces, and it's getting quite good for gaming as well. With that said, there's definitely a learning curve when you're switching over from a Mac or Windows PC. Even trivial things such as changing your password can get a bit complicated.
However, it's much easier than it sounds. Like with most things on Linux, you can use a couple of quick terminal commands to get the job done. You can even use it to recover your forgotten password, even if you can't log into the OS! We'll be showing you how to do so, and if you're not comfortable with the terminal, we have a method that works without it too.

University of Toronto ☛ Setting up an IPv6 gateway on an Ubuntu 22.04 server with WireGuard
Recently we enabled IPv6 on one of our networks here (for initial testing purposes), but not the network that my office workstation is on. Naturally I decided that I wanted my office workstation to have IPv6 anyway, by using WireGuard to tunnel IPv6 to it from an IPv6 enabled Ubuntu 22.04 server on that network. For my sins, I also decided to do this the more or less proper way, which is to say through systemd-networkd, instead of through hand-rolled scripts.
