TkKasse is a cash desk (POS) software designed especially for use in restaurants. It runs on ordinary PCs that use cheap standard components, aside from a POS printer. It supports multiple simultaneous waiters, bills, and screens. This software has been tested and optimized on real waiters at a restaurant in Harz Mountains, Germany.
SLOCCount is a suite of programs for counting physical source lines of code (SLOC) in possibly large software systems. It can count physical SLOC for a wide number of languages. It can take a large set of files and automatically categorize their types using a number of different heuristics, and also comes with analysis tools.
jMax is a visual programming environment for building interactive real-time musical and multimedia applications by allowing the user to interactively design dataflow circuits. The basic data types that can go through are integers, symbols, lists, etc. It is an event-driven system and has been used for MIDI processing. A second part of the system (DSP) allows a continuous signal to flow through a circuit, which is most useful for PCM sound (ie. microphone, sound files, etc.). The system is extensible by using shared libraries, you may add data processor types, data types, GUI elements, device types, and more. Data processors may also be designed as circuits and reused.
TkSQL allows you to edit the tables of PostgreSQL and MySQL databases. You can use it from the shell prompt, specifying the name of a table, or an SQL satement, or just the name of a database. It has filter capabilities which are very easy to use. Two views are possible (tables and form) and both views can coexist. TkSQL can edit a join of two tables (limited to the first of such tables). Totals and subtotals can be done quickly, and displayed inline with the data or in a separate window. Queries can be created in no time and all working conditions can be saved at once (comprising subtotals, relative time constraints, layout, etc.). It also provides basic tools for creating tables.
The Freehand Formula Entry System is a research prototype for recognizing online handwritten mathematical notation, developed jointly by researchers in New Zealand, the United States and Canada. A user draws expressions with a mouse or data tablet, and LaTeX, a bitmap, and an operator tree are produced as output. Symbol recognition and expression interpretation are performed as the user draws.
The BRU Backup and Restore Utility features data-verified backups, scalability, configurability, and ease of use for Linux and Unix. Versions are available for Linux, FreeBSD, and most UNIX variants. It works via an X11 interface, command line interactive, or through a scripted, scheduled (CRON) mechanism.
