Python-digest #15. News, interesting projects, articles and interviews [18 Feb 2013 — 23 Feb 2014]
News for today was not very much, but they are quite interesting. There will be games and developing for mobile devices, and audio processing and a good overview of ORM, as well as news goodness from Pewee. In addition, we are fast approaching the conference Kazan (it will take place on March 1). I take this opportunity to congratulate defenders of Fatherland on the last day of February 23 and all-all-all with the overall win in the Olympics.
Thank you owlman75 for the illustration and kind words, thanks to which I decided to do the show, despite the fact that overwhelmed the promised time and was faced with personal problems.
Please help — maybe someone could share or develop a UserScript to auto-fill images on habrastorage? He I greatly speed up the process of publication.
