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

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

I do not stop thanking owlman75 for the illustration. Even a vacation is not a hindrance to him. And thank you very much for the news that you send - they help me a lot to believe that the project is not for me alone.

I ask you not to forget to put pluses - if the post picks them up more than 50 (and I believe that this will happen at least someday), then good-natured will give me money.
