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.
ObexTool is a graphical frontend for ObexFTP, which is able to communicate with mobiles and other devices using the Obex Protocol.

File Juicer is a tool that extracts images, video, audio, or text from files which you can not open in any other way. It extracts JPEG, PNG, GIF, PDF, BMP, WMF, EMF, PICT, TIFF, Flash, Zip, HTML, WAV, AVI, MOV, MP4, MPG, MP3, AIFF, AU, WMV, or text from files containing data in those formats. It is useful if you have old files that cannot be opened with current applications, for emails with attachments you cannot open, for corrupt files or databases, for damaged or accidentally erased digital camera flash cards, and self extracting .exe files designed for Windows. It also extracts ZIP, SWF, RAR, and CAB files from some EXE files.
BleachBit deletes junk to recover disk space and maintain privacy. It rids your system of old junk including cache, Internet history, temporary files, unused locale files (better than localepurge), logs, and cookies. Designed for Linux systems, it wipes clean 50 applications including Adobe Reader, Bash, Firefox, Flash, OpenOffice.org, Opera, Real Player, Skype, and more. It shreds files so that they cannot be recovered, and it wipes free disk space to hide insecurely deleted files. It offers both a simple PyGTK GUI and a command line interface for automation.
