O2OO reads sensor data from a car into a sqlite database and generates graphs of the data so you can analyze the behavior of the car. It can also retrieve the location from a GPS module and store it in the same database, then can create a Google Maps KML-file, coloring the route line with a color depending on a sensor reading.
se is a screen-oriented version of the classic UNIX text editor ed. The editor implements many of the commands of ed, but instead of being line-oriented, se is screen-oriented. The command syntax is very familiar to users who already know ed. If you get stuck, there is a built-in help system that describes many of the available commands. Many configurable options can be loaded from a .serc file. se can be run interactively or in a script via the included scriptse utility. The editor is portable across many platforms, supporting major Linux and BSD distributions as well as other systems like GNU, Minix, Haiku, OpenSolaris, and Cygwin.
Speedpad is a small and portable ncurses-powered tool to test, train, and increase typing speed on arbitrary text input. It is designed for intermediate-to-advanced level typists and assumes that you have already learned how to touch type. It does not use lessons, single words, or other synthetic stuff. It supports tab expansion, auto indentation, and syntax to train on code. It features a reference speed robot and supports CPS, CPM, WPM, PPM, and CPH/KPH metrics. It shows detailed statistics about speed and helps find and eliminate frequent typos. Stats are dumped to standard output in a machine-readable format after completion, and can be piped into gnuplot.
