The CPU beep is a really irritating thing in Linux distros and sometimes the graphical sound manager does not work when shutting it up.
Fortunately there is a simple way to do it in terminal. In Ubuntu (and distros based upon it) type:
gksudo gedit /etc/modprobe.d/blacklist
In Debian type:
Phoronix: "Back in January, we published the first benchmarks of Debian GNU/kFreeBSD: the spin of Debian that replaces the Linux kernel with the FreeBSD kernel while retaining most of the same GNU user-land and it uses the GNU C library. With those original tests comparing Debian GNU/Linux to Debian GNU/kFreeBSD, the Linux version ended up winning in 18 of the 27 tests."
In 2005, the Debian project voted to declassify messages on the debian-private mailing list after a period of three years. That is easier said than done, apparently. The General Resolution (GR) calls for volunteers to do the work of declassification, and few Debian Developers seem eager to do the work required to make it happen.
Linux Journal: "My new thing in these situations is to deploy the latest Debian in a slimmed down form. The advantage is that you end up with a completely up to date Linux distribution and it's still standard Debian underneath it all."
