BallroomDJ is a ballroom music player. It is designed to let the computer choose the music and to be able to play music the entire evening without intervention. The choice of music is based on the choice and weighting of different dances by the user and the use of various rules to choose which dance to play next. The rules are: avoid repetition of the dance, avoid sequences of dances of similar types, avoid sequences of dances of similar speeds, and avoid sequences of dances from the same family of dance.
KAlarm lets you schedule personal messages to display, audio files to play, commands to execute, or emails to send. Among its options, it allows you to choose the message font and color, recurrence schedule, whether to display an advance reminder, whether to speak the message or play a sound when it is displayed, and whether to cancel the alarm if it can't be triggered on time (e.g. if you are logged out at the time). As well as using the graphical interface to configure alarms, you can use the command line, and there is a D-Bus/DCOP interface for other applications.
Atmail is a fully-featured email server and Webmail client, allowing users to send and receive email via a Web browser or mobile device. It has full support for IMAP mailboxes, and an optional email-server mode that uses EXIM as the MTA. Features include a scheduler, MySQL backend support, spell-check, address book, calendar user preferences, multiple accounts, SpamAssassin support, migration scripts from other mail servers, a customizable interface, an attractive AJAX interface, an optional group sharing Calendar/Addressbook, and an Outlook plugin to sync Contacts/Tasks/Calendar data between a Desktop, Mobile, and Webmail client or other email users.
The "fmconv" script modifies the /etc/fstab file and the /boot/grub/menu.lst file to use either UUID strings or device filenames depending upon the parameter settings (-u or -d). This easy conversion to device filenames for maintenance purposes (UUID strings are hard to maintain, and just annoying), and the conversion back to UUID strings allows grub to work in an environment where the boot disk sequence is poorly defined by the BIOS. The original files are never overwritten.
