libdmtx is a software library that enables programs to read and write Data Matrix (or "DataMatrix") 2D barcodes. It runs on several platforms, and can be accessed by multiple languages. The package provides fully featured command line utilities.
Converter of various scalable font formats (most notably TTF) and of the bitmapped BDF format into PostScript Type 1 fonts and metrics (.pfa, .pfb, .afm).
Earth orbits and coverage display in 3D on your laptop.
SaVi - simulate Iridium, Globalstar, O3b, Sirius Radio, GPS, Galileo and other satellite constellations, modify them, or design your own. Uses Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.
Modify the variable/object/function/method names within a compiled swf to make it almost impossible to read. flmObf DOES NOT STOP DECOMILATION, it merely makes the decompiled code harder to understand!
A set of shell scripts and helper programs (written in C) for creating a html index of your photo collections. Handles resizing, jpg->png conversion, styles and maps for your trips. Highly customizable. To be run in unix-like enviroments.
To provide users with a customized rendering pipeline, right down to how the bounding code bounds. TRRT is about providing the rendering pipeline you want and need, whether you render at a professional or hobbyist level. Will be RenderMan compliant.
In short, this utility takes screenshots and uploads them to a remote server. This utility is advanced: it provides the user with a very comfortable text-based interface. There are two modes available: interactive and automatic. Will be developed.
similar - a program for detecting duplicate images, simv - an extensible image file mover, and snntpbatch - a batch oriented newsgroups client. They are mainly intended for Linux but should be quite portable.
