Python-digest # 13. News, interesting projects, articles and interviews [January 31, 2014 - February 9, 2014]

Oh, how he knew that the damn dozen is not a good number. This time the release of fresh news about python and nearby technologies was late. The reason for this dam at work. In fact, preparing a digest even with already prepared news takes quite a long time. We'll have to postpone issues on Saturday, so that I do them calmly and there were no breakdowns like this time.


I want to say the traditional thanks to owlman75 for the illustration to the release. It is still readonly, but it is possible that it will publish an interesting article suitable for our digest and will receive an invitation from someone. They say it often does a UFO.

There are not very many articles this week. Everyone who receives PythonWeekly and PythonCoders will not be allowed to lie - there was nothing particularly interesting there either. I want to say that we create the informational background of the python community ourselves - therefore, support your favorite language program: write articles, advertise your interesting projects, experiment with innovations.
