RealTime Application Interface (RTAI) lets you write applications with strict timing constraints for GNU/Linux operating system. Version 3.8.1 has been released. Main differences between 3.8 and 3.8.1 are in the substantial updates to RTAI-Lab and various fixes 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. In this new version of Xenomai (2.5.3), here is some of optimizations, cleanups, improvements and bug fixes:

For detailed commit logs, see git shortlog.

• Extensive temperature derivative fixes;
• Hardcoded tunneling constants (3.7622e-7, -3.1051e10) for Igb1 replaced with agb1, bgb1 and hardcoded tunneling constants (4.9758e-7, -2.357e10) for Igb2 replaced with agb2, bgb2;
• Following variables are added double eggdep, agbc2n, agbc2p, bgbc2n, bgbc2p;
• ...and so on!

XtreemOS project aims at building a GNU/Linux-based operating system to support virtual organizations for next generation grids. The overall objective of the XtreemOS project is the design, implementation, evaluation, and distribution of a grid operating system (called XtreemOS) with native support for virtual organizations (VO). XtreemOS is capable of running on a wide range of underlying platforms, from clusters to mobiles. It is based on Mandriva Linux, with support to come for other distributions later. It is characterised by properties such as transparency, hiding the complexity of in the underlying distributed infrastructure; scalability, supporting hundreds of thousands of nodes and millions of users; and dependability, providing reliability, highly availability and security. Team XtreemOS announce the sixth release candidate of the second public version of the XtreemOS Grid Operating System. This update release includes:

GTKWave is a fully featured GTK+ based wave viewer for Unix and GNU/Linux which reads LXT, LXT2, VZT, and GHW files as well as standard Verilog VCD/EVCD files and allows their viewing. The new release fixes some problems/bugs and adds new functions, i.e.;

• Added RealToBits menu options for displaying real numbers as binary values;
• Added preliminary transaction filter support;
• Updated time warp handling;
• Incorporated FST writer optimizations;
• Incorporated some fixes suggested by cppcheck;
• Added transaction parser in examples/ directory.

Piklab is an integrated development environment (IDE) for applications based on Microchip PIC and dsPIC microcontrollers. It integrates with several compiler and assembler toolchains (like gputils, sdcc, c18) and with the GPSim simulator. It supports the most common programmers (serial, parallel, ICD2, Pickit2, PicStart+), the ICD2 debugger, and several bootloaders (Tiny, Pickit2, and Picdem). In this new version of Piklab;
