K4DirStat (KDE Directory Statistics) is a small utility program that sums up disk usage for directory trees, very much like the Unix 'du' command. It displays the disk space used up by a directory tree, both numerically and graphically. It is network transparent (i.e., you can use it to sum up FTP servers), and comes with predefined and user configurable cleanup actions. You can directly open a directory branch in Konqueror or the shell of your choice, compress it to a .tar.bz2 archive, or define your own cleanup actions.

Konqueror is the KDE web browser and advanced file manager.

System-config-lvm provides a graphical interface to the LVM tools (and related utilities, including fsck and resize2fs) which is good for non-emergency storage administration. It enables you to manage your logical volume and filesystem configuration with a few mouse clicks, and it prevents potentially- disasterous command-line mistakes such as reducing a logical volume size before reducing the filesystem contained within that volume.

The object of the game is basically the same as in Tetris; use the pieces that fall down from the top of the game area to construct fully filled lines, which will then disappear to make room for more pieces. The twist is that the pieces are composed of hexagonal blocks, so your visualization skills will get an extra workout.

IDLE is an Integrated Development Environment for Python (v2.7). IDLE is written using Tkinter and therefore quite platform-independent.

Task Coach is a friendly open source todo manager to manage personal tasks and todo lists. It supports composite tasks, i.e. tasks within tasks. In addition, Task Coach allows you to categorize your tasks, track effort against a budget per task, and much more. Task Coach is available for Windows, Mac OS X, BSD, Linux, iPhone and iPad.
