The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.
wsdebug is a debugger for the more or less famous WhiteSpace programming language, coming along with a rather fast interpreter, entirely coded in ISO-C. WhiteSpace is another geeky language to code in, just like Brainfuck and others.
Free MSP430 Debugger is developed in two steps : a library to provide access to the debugger hardware, and a "gdbproxy" to allow users to debug their software. This project is currently working with OLIMEX MSP430 JTAG ISO & msp430-gdbproxy.
