Python-digest # 24. News, interesting projects, articles and interviews [April 20, 2014 - April 27, 2014]

And again, a selection of articles, releases and interesting projects about python and nearby technologies. Today there will be Haskell, ninjas, clicks, cocaine - in general, everything you need for a good show.

I do not cease to thank owlman75 for the illustration. Even his vacation is not a hindrance. And thank you very much for the news you send - they really help me to believe that the project is needed not only by me.

I ask you not to forget to put a plus sign - if the post collects more than 50 of them (and I believe that such a thing ever happens), then the well-servant will give me a coin.
