I wrote this stuff for me, but if you find it useful, enjoy.
A program called Mailleds inspired this program. The idea was to
blink an led on the keyboard when new mail is waiting (actually,
Mailleds has many other features, but this was the feature I
wanted). It didn't work for me, so I wrote my own. It is released
under GNU Public license.

I have always been suspicious that password generating programs
were not as random as they should be. So I wrote my own with that
principle in mind. Unlike most programs, it asks for the amount of
entropy that should be in the password rather than the length. It then
generates a password long enough to have the approximate required entropy.

Piano Partner is a simple tone generator written in Perl. I wrote it for Linux to assist me tuning pianos to equal temperament, although technically I suppose it would work with other operating systems without much trouble. It depends on mpg123 for playing sound samples, and libgtk2-gladexml-perl for the interface.
The program is minimal and simple to use. Pick a note and press Play to play that frequency for 40 seconds. The hard part of course is getting your piano to sound the way it should.

To emphasize to a class that JavaScript is a complete
programming language I decided to implement something useful in it
(i.e. not flashing buttons). The results are these Javascript
implementations of Base64 MIME encoding, and the Tiny Encryption
Algorithm TEA. They
are compatible with the
MIME::Base64,
Crypt::CBC,
Crypt::TEA Perl
modules (note: for full TEA compatibility, use passwords no more than 16
chars long).

Xkeyspy is a small utility that connects to your X session and
displays your keystrokes. Compiled fine for me on Linux, AIX, and
Solaris.

I have two Perl scripts for controlling X10 lighting. The first is linc which is a command-line tool that can send commands through a PowerLinc serial controller. My script is not quite as elaborate as others you may find on the net, but it should be pretty easy to understand and customize. And it works for me.
The second script is x10.pl which requires two other files, x10.glade and x10icon.png. It builds on linc and features a gui that resembles the X10 Palm Pad remote. Like linc, it should be easy for any Perl programmer to customize.
