Python-digest # 6. News, interesting projects, articles and interviews [December 6, 2013 - December 13, 2013]

We continue to search for interesting information about your favorite programming language and nearby technologies. This time, Python Weekly announced fewer events than usual, but we found a lot of interesting things for you without them. So much so that we were banned from Juick for repost. So the only resource from which you can quickly take the news was only our rss.

I offer 500 Yandex money for translating the article “Why I hate pip and virtualenv” on Habré - it seems decent.
Translated by lightman

Many thanks to owlman for the illustration and axce1 for supporting the digest tool. Soon there it will be possible to post news feeds anonymously.
