NetworkX in Orange
NetworkX – a popular open-source python library for network analysis has finally found its way into Orange. It is now used as a base class for network representation in all Orange modules and widgets. By that, we offered to the widespread network community a fruitful and fun way to visualize and explore networks, using their existing NetworkX scripts. It has never been easier to combine network analysis and visualization with existing machine learning and data discovery methods.

Orange GSoC: Multi-label Classification Implementation
Multi-label classification is one of the three projects of Google Summer Code 2011 for Orange. The main goal is to extend the Orange to support multi-label, including dataset support, two basic multi-label classifications-problem-transformation methods & algorithm adaptation methods, evaluation measures, GUI support, documentation, testing, and so on. My name is Wencan Luo, from China. I’m very happy to work with my mentor Matija. Until now, we have finished a framework for multi-label support for Orange.

Fink packages now also 64-bit
Fink packages (we are using for system-wide Orange installations on Mac OS X) were updated to 64-bit. So if you were using 64-bit Fink installation you will be now able also to use Orange (and our binary Fink repository of already compiled packages). Just use this this installation script to configure your local Fink installation to use our binary Fink repository and add information about Orange packages (they are not available among official Fink packages).

Orange GSoC: Visualizations with Qt
Hello, my name is Miha Čančula and this summer I’m working on Orange as part of Google’s Summer of Code program, mentored by Miha Štajdohar. My task is to replace the current visualization framework based on Qwt with a custom library, depending only on Qt. This library will better support Orange’s very specific visualizations and will replace the unmaintained PyQwt. I have a lot of experience with Qt and its graphics classes, both in C++ and Python, but I’m relatively now to Orange.

Debian packages for Squeeze
We have updated our daily Debian packages to Squeeze (current Debian stable). You just have to reconfigure our package repository in your /etc/apt/sources.list to: deb http://orange.biolab.si/debian squeeze main deb-src http://orange.biolab.si/debian squeeze main Those packages are compiled for Python 2.6. You can read more about Debian packages in our old blog post.

Orange GSoC: MF Techniques for Data Mining
I am one of three students who are working on GSoC projects for Orange this year. The objective of the project Matrix Factorization Techniques for Data Mining is to provide the Orange community with a unified and efficient interface to matrix factorization algorithms and methods. For that purpose I have been developing a library which will include a number of published factorization algorithms and initialization methods and will facilitate combinations of these to produce new strategies.

Orange 2.5 progress
We decided that we should reorganize Orange to provide more intuitive interface to the scripting interface. The next release, Orange 2.5 is getting better every day. But fear not, dear reader, we are working hard to ensure that your scripts will still work. In the last morning of the camp in Bohinj we decided to use undercase_separated names instead of CamelCase. We have been steadily converting them and the deprecation utilities by Aleš help a lot.
