I use the VIM editor.  Alot.  That means that I get beeped at.  Alot.  As a note to those who haven’t used VIM, it beeps through the system speaker, not your normal speakers.  The system beeper is an especially annoying relic, leftover from two decades ago when a system beep was actually useful. I’d finally had enough, so I figured out how to turn it off.  It turns out that (like everything else) it’s extremely easy in Ubuntu.

System -> Preferences -> Sound -> System Beep -> Enable System Beep

I unchecked that puppy, and now my computer my computer doesn’t make a sound (except of course, the hum of 8 fans pushing 1,000cfm of air across my OC’d mobo).
