Maxima is a fairly complete computer algebra system written in Common Lisp with an emphasis on symbolic computation. It is based on DOE-MACSYMA and licensed under the GPL. Its abilities include symbolic integration, 3D plotting, and an ODE (Ordinary Differential Equations) solver.
It is full featured, doing symbolic manipulation of polynomials, matrices, rational functions, integration, Todd-coxeter, graphing, bigfloats and so on. It has, also, a symbolic debugger source level debugger for maxima code.
A new version (5.32.0) of Maxima has been released. Some changes are:
- Better implementation of max-exponent;
- Update of the Plotting section of the manual;
- New options added to save output in SVG, PNG or PDF formats;
- Fixes a bug in plot2d-discrete and implements a feature requested;
- Adds several new options for the plotting programs (e.g.: grid2d, label, samexy, samexyz, xyscale, yxratio etc);
- Fixes many bugs, e.g.: Bigfloat Gamma Inaccurate for Small Inputs, Correction for $matrix evaluation, elliptic_kc(3.0) not accurate, Numeric evaluation of inverse Jacobi elliptic functions is wrong for some inputs, Erroneous limit result, fix "limit(-(3*n^2 + 1)*(-1)^n/sqrt(n^5 + 8*n^3 + 8),n,inf)" etc.
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.
Fritzing can be seen as an Electronic Design Automation (EDA) tool. The input metaphor is inspired by the environment of designers (the breadboard-based prototype), so that it is easy to transfer a hardware sketch to the software by using a drag-and-drop-based GUI to copy your sketch.
In this new version of Fritzing a high-level summary of changes are:
- An handful of styling changes;
- ICSP and ICSP-less Arduino;
- Fixed an infinite loop at startup for some languages;
- Welcome View print crash fixed;
- Fixed Arduino swap crash.

LabPlot is a KDE Application for plotting and analysis of 2d and 3d functions and data.
LabPlot allows you to work with multiple plots which each can have multiple graphs. The graphs can be produced from data or from functions. All settings of a complete set of plots can be saved in a project files.
LabPlot also provides a component for easily viewing the project files in Konqueror.
Since the last beta release two month ago some changes are done:
- Couple of bugs were fixed;
- Some polishment and cleanup in the code was done.
KLayout is a Qt-based viewer and editor for GDS2 and OASIS integrated circuit layouts for the chip design engineer.
The main objective is to focus on the basic functionality but adding some useful features that many, even commercial viewers don't have, e.g., shows the design as it is and to animate ayers to make them blink or scroll the fill pattern.
A new version of KLayout has been released. In this new mantainance release:
- Bugfix: RBA SimplePolygon#inside? and Polygon#inside? now work as expected;
- Bugfix: DRC output to marker browser now works as expected;
- Bugfix: HTTP URL's now are written as such into the MRU list;
- Bugfix: A net tracer crash was fixed;
- Bugfix: Net tracer connectivity setup: the move buttons now work as expected;
- Bugfix: a DRC issue was fixed when assigning the output of modifying operations;
- Bugfix: some memory and static code analysis issues have been fixed after analysis with valgrind, clang and Coverity;
- Enhancement: compatibility with clang 3.3 was established as well as compatibility with Ruby 2.0
