gds2000tools is a collection of command line tools for using the GW Instek oscilloscopes on GNU/Linux. A new version of gds2000tools has been released. This release contains:

• gds-template-get added, for reading go/no-go templates from GDS-8x0 series oscilloscopes;
• More checks if intermediate commands fail;
• gds-esr: output formating fixed;
• Format option 'go-nogo' added for reading and decoding GDS-8x0 series oscilloscope go/no-go template data;
• Support for Rigol DG5000 series.

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 4.5.1 has been released. In this version a total of 37 new functions were added since version 4.4.4 then the total number of functions is now at 25764 (overall weighted coverage score: 82.7%). Some changes in this release are:

• Error in quotient ring loaded from a file;
• Multi-dimensional polynomial fit;
• Add an spkg-check file for Python;
• Recognition of split graphs (5 lines);
• Upgrade biopython package to 1.54.

Sage 4.5.1 closed 92 tickets (since 4.4.4 version), all of which are available here (version 4.4.4 -> 4.5) and here (version 4.5 -> 4.5.1) for your reading pleasure.

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 a high-level summary of changes are:

• GNU/Linux x86-32: crashing at 70% file load (with jumper items) fixed;
• Crash bug on some of the sparkfun footprints converted from Eagle/KiCAD;
• Experimental KiCAD schematic (lib) file import;
• A few bug fixes.

Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail. Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters. The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics. In this new version of Baudline:

FSMDesigner4 is a C++ based implementation for a Finite State Machine (FSM) design tool with integrated Hardware Description Language (HDL) generation. FSMDesigner4 uses the Simple-Moore FSM model guaranteeing efficient fast complex control circuits. In this new version of FSMDesigner4:

• Many new features implemented;
• A new GUI.

Heyu provides a command line interface to communicate with the CM11A hardware module from X10. Heyu can be run from cron to automate lights, sprinklers, etc., or can store macros and timers in the CM11A memory for standalone operation. Auxiliary input is supported from MR26A, W800RF32A, and RFXCOM X10 RF receivers for X10, X10 Security, RFXSensor, RFXMeter, Oregon, and DigiMax RF signals (subject to the capabilities of the receiver). Version 2.9.0 of Heyu adds new features, enhancements and fixes various bug, e.g.:

• Added command 'heyu masklist' to display the current list of mask environment variables for ready reference;
• Added module type BMB-SD18 for the BMB model SD18 Smoke Detector;
• Added module type DS18-1 for the ElekHomica DS18 Security Door/Window sensor;
• Added the capability for one signal to launch more than one SCRIPT.
