Open Source Pixels

Trouble started when I wanted to send some files to my phone from laptop via the bluetooth. (You see I happen to be among the unfortunate set of people who have the same button for enabling wireless and bluetooth.) I tried enabling the laptop’s bluetooth when the whole system came to a standstill

The PyPy
1.5 release is out. PyPy is an alternative Python interpreter with a
focus on speed. “This release updates PyPy with the features of
CPython 2.7.1, including the standard library. Thus all the features of
CPython 2.6 and CPython 2.7 are now supported. It also contains additional
performance improvements.“

gEcrit is a source code editor oriented toward Python. It tries to keep the interface as clean as possible and keep the menus simple. It features all the common features a Python programmer might need, including an interactive Python interpreter and operating system shell. It supports a plugin system for expandability.

Changes: This version adds session support for the editor. It can save all the open tabs, window layout, and selected document and restore them at startup. A plugin was added that allows you to have an unlimited number of terminals for any shells. All it needs is a path to the shell interpreter. The spell checker was moved to a plugin and now it is possible to spell check a text selection. A document clone plugin was added. The default text function was moved to a plugin called StampIt.

Psensor is a graphical hardware temperature monitor for Linux. It can monitor temperatures of the different hardware sensors (motherboard and CPU using lm-sensors), hard disk drives (hddtemp), and Nvidia GPUs. The fan can also be monitored (lm-sensors). Psensor is designed to be simple and easy to use.

Changes: This release fixes a UI freeze when selecting preferences by using the application indicator of Ubuntu Natty. It adds partial support of the Turkish language and a full support of the French language.

Chips is a Python library for designing hardware devices that provides a high-level device modelling language. Native simulations integrate with Python so you can use Python extension modules such as Scipy, Numpy, Matplotlib, and PIL to provide a rich verification environment. Device models can be automatically translated into synthesizable VHDL, and highly optimized soft-processors are generated for an efficient implementation. A plugin mechanism is provided so that additional code generators can be added. C++ and Graphviz plugins are provided. Existing VHDL IP can be imported, and seamless co-simulation of C++ and VHDL outputs is is supported.

Changes: This is the first release.

Mathomatic is a portable, general-purpose computer algebra system (CAS) that can solve, differentiate, simplify, combine, and compare algebraic equations, perform standard, complex number, and polynomial arithmetic, etc. It does some calculus and is very easy to compile, learn, and use. The symbolic math application with a simple command-line interface is designed to be a colorful algebra calculator that is reliable, responsive, convenient, and comfortable to use. The symbolic math library is lightweight and easy to include in other software, due to being written entirely in C with no additional dependencies.

Changes: The polynomial factoring and polynomial division C code was finished and cleaned up, so polynomial operations give better results and are 30 times faster in some cases. The "simplify quick" option gives much better results now, sometimes better than any other simplify option. The coloring scheme was improved: all prompt and normal text is now the terminal emulator’s default color for text (usually uncolored); expressions remain colored if color mode is enabled. m4 Mathomatic can now easily be made to work under BSD Unix.
