mailq_applet is a GNOME 1 panel applet that shows the status of your outgoing mail queue. It's intended for dialup users who may connect, wait for the queue to drain, then disconnect. Having this on your panel is much more convenient than running mailq over and over again from a terminal. It works with Exim and Sendmail. If you use a different MTA, you may need to make some changes, but the code is so trivial that that shouldn't be difficult. This code is no longer used or maintained by its author.
md5mon is a shell script that verifies files by computing their checksums. The script is suitable for use as a basic security checking tool from cron. It features configurable monitoring levels, local copies of find/md5sum, and integrity checks to prevent tampering with itself. It can also use a more secure shasum instead of md5sum.
MotionView is a Java application that allows you to view, scan, fast-forward, and reverse through the images captured by the Motion motion-detection and video capture software for Video4Linux.

mp3album.pl is a tool to automatically create album lists from a batch of mp3 files including ID3v1, ID3v2.2 or ID3v2.3 information. It includes logic to split up all files in one directory into separate albums and generates a report file for each album. The reports are customizable through templates and can contain any information found in the ID3 tags. mp3album.pl lends itself very handy when creating an index of a directory containing several albums of music. As Perl currently lacks 'good' Unicode support, the Unicode strings in ID3v2.3 are not yet supported.
MyPhotoAlbum is a simple, small, easy to use web photo album. It allows the user to create albums/categories and upload pictures with titles and comments, and keep the albums in several languages simultaneously. The title and comments are stored in plain text files. No database server is needed. MyPhotoAlbum uses CSS for its web formatting to have maximum control over its look and feel. It has a main screen that shows the photo albums. On each album screen, thumbnails with titles and comments are displayed. Clicking on the thumbnail will display a pop-up with the picture full-size.
