Castle Game Engine is a cross-platform 3D game engine written in Object Pascal. It includes a flexible system of 3D objects, with out-of-the-box levels, items, intelligent creatures, and more. Rendering and processing of 3D models in X3D, VRML, Collada, and other formats is implemented. Many graphic effects are available, including shadows, bump mapping, shaders, mirrors, and screen effects.
cduino is a microcontroller programming system that is like arduino but simpler. It allows experienced programmers to get a quick start programming and talking to a microcontroller. You should be up and talking to your arduino over the serial line in a matter of minutes. This is achieved using a very easy Makefile-based driver for the command line Atmel AVR programming tools, a library of C routines, and a series of lessons that introduce a variety of AVR subsystems.
Opdis is a wrapper for the libopcodes disassembler library distributed as part of GNU binutils. It extends the libopcodes library by offering linear and control-flow disassembly algorithms, instruction and operand objects that are suitable for analysis, and a command-line utility to perform disassembly on arbitrary locations in a file. The Opdis project consists of the libopdis library and the opdis command-line utility. There is a Ruby gem providing access to libopdis, and a supporting gem providing access to libbfd.
