trojuhelnik is a general solver for triangles. It computes all possible solutions for a triangle that is specified by an arbitrary triple of the following elements: sides, angles, altitudes, medians, angle bisectors, area, radius of circumscribed and inscribed circle, sum a+b, perimeter and difference of the angles. All other elements, triangle visualization, and graphs of elements dependencies are also available.
Trowser is a browser for large line-oriented text files (such as debug traces). It's meant as an alternative to "less". Compared to less, trowser adds color highlighting, a persistent search history, graphical bookmarking, separate search result windows, and flexible skipping of input from pipes to STDIN. Trowser has a graphical interface, but is designed to allow browsing via the keyboard at least to the same extent as less. Key bindings and the cursor positioning concept are derived from vim.
tvpvrd is a PVR daemon for Linux that offers the ability to schedule and manage TV recordings using one or multiple installed analogue TV capture cards, e.g. Hauppauge. The daemon is interfaced either through its full command language via a provided command line shell or through a basic (built-in) Web interface provided by the built in micro Web server. The goal is to provide an advanced recording and transcoding (using ffmpeg) server without the need to configure databases or a complex GUI. The server is completely self-contained and uses an XML DB in plain text format to store future recordings.
