decloak is a utility that endeavors to find hidden processes via PID exhaustion. It exploits the linear manner in which PIDs are assigned to new processes to reveal unseen processes. When a process is found, the script checks a few functions such as getpriority, getsid, getpgid, and the contents of /proc/(pid)/cmdline and reports them.
OpenHTMM is an implementation specifically designed to facilitate research into Hidden Topic Markov Models methods. Hidden Topic Markov Models (HTMM) is a method of analyzing a docyment by imposing a temporal Markov structure on the document. In this way, it is able to account for shifting topics within a document. In so doing, it provides a topic segmentation within the document and also seems to effectively distinguish among multiple senses that the same word may have in different contexts within the same document.
Kolorizer is a KDE application which makes it easy to adjust colors in certain files. It supports all text files that specify colors with six-digit hexidecimal numbers. Examples of these files are CSS (Cascading Style Sheets) and gtkrc (GTK theme files). It lists buttons with the colors it found. By clicking on a button one can change the color. Its most remarkable feature is a slider that lets you adjust all colors at once by rotating the hue.
DeadlyCobra is a game similar in gameplay to the classic Nibbles or snake game. Basically the point of the game is to eat as many pebbles (in this case "Men") as possible without eating yourself or hitting a wall. Features include both single and multiplayer modes, cool 2-D graphics and energizing music for each level.
Kandau is a library that offers an easy way to store and retrieve C++ objects (and their relations with other objects) into various backends. SQL, XML, and .desktop backends are currently implemented. It may be as interesting for storing configuration information as it is for storing information in a relational database. Furthermore, you can switch the backend without any change to source code, and it is thus transparent to the application developer.
