Just get in the habit of checking for your keys before you go through any door. It takes no mental effort once it’s a habit. If they aren’t in your pocket (or in my case a lanyard) then they are in that room or vehicle, so you should recover them before going out. This method worked for me 100% for decades. It only failed after I got married and my wife started stealing them. But it’s usually not too hard to find her.

No toca los PopOS!

My neighbor at the trailer park was a janitor at the university. I built my computer from parts he salvaged from the recycle bin, and put Redhat 5 on it.

Presets for EasyEffects and PulseEffects.

On Debian, there is a package that displays system documentation including, if I remember correctly, man pages. I think I had to set up a local web server first.

On Archlinux at least, the glibc package includes info pages for C functions. Just type info libc at the command line, or use info inside emacs. There are hyperlinks in info pages, it’s a nicer interface than man pages.

PulseEffects can moderate the high-volumed sounds too. It has a complex set of controls and filters, and I’m not a sound engineer, so I just followed someone else’s recipe.

I don’t have any need to edit markdown, but I sometimes use Marker: “Simple yet robust Markdown editor made with GTK” as a viewer.

It might be possible to boot into a bootable image from grub so you don’t need to set up another bootable partition.

Or you could disable your display manager in systemd. This will start in console, then if you want X just run startx.

Or you could change your display manager to Lemur, which supports X, Wayland, and TTY sessions.

Or you could just press control-alt-F2 at the login screen to switch to a console.
