kugel is a perl/tk based game that is played by moving objects on the board and putting them into rows, columns, diagonals. Each time you create a line of the same objects, the score will increment with the number of objects you accomplished to line up. In the same time, the lined up "kugels" will disappear, so you can continue the game with more maneuver space on the board. Any time you fail to create a line of "kugels", new ones will appear on the board. Once the board is full, the game is over.
KWC (Key Width Calculator) calculates the bit count required to represent a specified number of combinations. It additionally calculates key width in platform bytes (C char type), actual number of combinations covered by that many bits, and the difference and ratio of requested and actual coverage.
krunseti starts SETI@home and displays its status. It can display the progress in the current work unit, the amount of completed work units, and the CPU time for the current and for all work units. The dock window displays the progress, too, and it can change its color to show what the SETI@home process is doing (running, aborted, or paused).
KSnuffle is a network packet sniffer for KDE. It supports multiple concurrent sniffers, packet filtering (aka tcpdump), event triggers and commands, text and binary logging (and replay), remote sniffing (via a demon process), and dynamically loadable plugins. Network traffic is displayed graphically and in detail; supplied plugins summarise traffic by direction (incoming, outgoing), source, and destination.
