GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. Octave 3.2.4 version has been released and is now available for ftp. This version fixes/improvements/adds new features, e.g.:

Xenomai is a real-time development framework cooperating with the Linux kernel, in order to provide a pervasive, interface-agnostic, hard real-time support to user-space applications, seamlessly integrated into the GNU/Linux environment. Xenomai 2.5.1. Here is some of optimizations, cleanups and bug fixes:

• I-pipe patch fixes and new versions, asm wrappers upgrades to cope with new patches;
• Drivers update; RTCAN, including new support for powerpc platforms analogy, including a new s526 driver.

Fritzing is an open-source initiative that allows you to virtually design electronic circuits on a breadboard (although you could design circuits that aren't on a breadboard). This could save a lot of hours working on a breadboard if you have this amazing software at hand. In this new version of Fritzing some individual code changes are:

MCU 8051 IDE is fully featured integrated development enviroment for MCS-51 based microcontrollers (e.g. AT89S8253) written in Tcl/Tk for POSIX systems only (like GNU/Linux). It consists of compiler, advanced text editor (highlighting, validation, completion), simulator, scientific calculator, hexeditor and many other things. In this new version of MCU 8051 IDE;
