To increase the activity of the site (one of the main concerns related to making Codidact grow), I suggested merging Linux Systems with Power Users on Meta. Do you agree or disagree with merging?
I am currently ripping a bunch of DVDs. Some are encrypted, and some are not. My method for ripping a DVD depends on whether or not it is encrypted, so I am looking for a command-line method to det...

For a particular use case, I need to be able to set up a Linux host (specifically Debian) to use a VPN tunnel for routing outgoing connections, but still allow incoming connections outside of that ...
Since asking this question I've updated to 12.2 (Monterey), but it's the same problem on either. I was nervous about blowing away my existing brew installation, even if I first captured a list of ...
While there doesn't seem to be a general command like notify-send to hide all notifications, we can use features of our specific notification daemon, like mako in this case, to hide all notificatio...

You can find a list of options in man xkeyboard-config. Under the section "key to choose the 3rd level" is the one you are after: lv3:ralt_switch_multikey Right Alt; Shift+Right Alt as Compo...
As we have set up communities here on the Codidact network we've been appointing temporary moderators. Ultimately, of course, we want each community to choose its own moderators; we've been doing ...
