QtiPlot is a program for two- and three-dimensional graphical presentation of data sets and for data analysis. The plots can be produced from data sets stored in tables or from analytical functions. It can be successfully used for teaching as well as for complex data analysis and visualisation and is being used in companies, high schools, universities and reseach institutes all over the world. QtiPlot in this new release adds new features, improvement and bug fixes, e.g.;

• Printing of 3D plots was improved;
• Localization was added to muparser scripts;
• Functions were added to the column values dialog, allowing you to calculate the sum or the mean of a range of cells in a table column;
• The possibility to define a default spacing between ticks and labels in 2D plots was added;
• A scientific label format with the German multiplication sign was added;
• Auto binning in histograms was improved;
• Detection of user defined constants in the 2D function dialog was implemented;
• The possibility to maximize the print preview dialog was added.

Here the complete list of changes.

Sage is an open source mathematics computing environment (MCE) which covers many aspects of mathematics, e.g. algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, group theory and so on. Sage 4.3.2 has been released. In this version a total of 197 new functions were added since version 4.3.1 increaseing doctest coverage by 0.2%, then the total number of functions is now at 24594 (overall weighted coverage score: 81.5%). Some changes in this release are:

• Fix ref manual issues in linear_code.py;
• Corrected some bugs in evaluation of spherical bessel function;
• Fix issue with multi_polynomial.pyx in sage-4.3.2.alpha0;
• Improvements to complex AGM.

Sage 4.3.2 closed 125 tickets, all of which are available here for your reading pleasure.

A PC instrumentation board, be it PCI, PCI-X, PCI Express, PXI or CompactPCI, transforms a standard PC to a universal powerful instrument. Compared to a stand-alone solution there are several advantages like best flexibility, data is rapidly available for calculation, a wide range of available software solutions, software programmable hardware settings for ease of use and highest performance, easy combination of different hardware possible and so on! Setting up a mixed mode system or stimulus-response test benches is no problem combining the wide range of multi channel A/D, D/A and Digital I/O cards with the internal card synchronisation. In contrast to stand-alone instruments which only have one fixed function, the modular instruments can turn into any kind of virtual instrument using the latest PC processing technology. Spectrum is a manufacturer for fast PCI, PXI, CompactPCI instruments. Used as ADC, DAC, transient recorder, data acquisition, signal generator, ARB, digital I/O, pattern generator, DAQ, oscilloscope. A new version of driver for GNU/Linux has been released. In this new version:

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.

PCAN-Light for LINUX is the easy to use software interface for CAN hardware by PEAK-System. There's a single API (Application Programming Interface) for all CAN interfaces. This simplifies the software development. The drivers are designed to work with CAN hardware by PEAK-System and 100 percent compatible hardware by OEM vendors. Take care when using third-party hardware, since the drivers use special functions. In this new version (6.15) of GNU/Linux driver;

• Fix a problem with PCAN-USB driver (Baudrate fix);
• New manual.
