Andrea Crotti\n#+TITLE: Iwoca at Europython\n#+OPTIONS: toc:nil num:nil ^:nil\n\nThis year I had the opportunity to represent iwoca at europython 2016.\n\nIt was a great conference with a great bunch of people, really well organised by the local team.\n\nAll the videos will be loaded on this channel when ready (but you can already find the raw footage from the live streaming):\nhttps://www.youtube.com/user/PythonItalia/videos\n\n* Bilbao\n\nEuropython was organised for the second year in Bilbao, in the Basque country in north of Spain.\n\nBilbao has been an industrial and quite polluted city for a long time,\nhowever in more recent years however the decline of the heavy\nindustries (which reduced pollution) and some famous architects gave it\ngreat push.\n\nIt's surrounded by green hills and close to the seaside, with some\ngreat food and very pleasant to work around, the perfect place for a\ntech conference.\n\nhttps://en.wikipedia.org/wiki/Guggenheim_Museum_Bilbao\n\n[[./images/bilbao_night.jpg]]\n[[./images/funicolar_view.jpg]]\n\n* Conference venue\n\nThe venue was in a great modern building next to the river.\nKudos to the organisers for the great work in decorating it so well, with lots of big tables and common areas which made it really easy to meet people and work together.\n\nVery nice also the idea of two foosball tables and two retro game machines powered by a raspberry PI, another great way to socialise.\n\n[[./images/venue_first.jpg]]\n\n[[./images/foosball.jpg]]\n\n[[./images/venue_river.jpg]]\n\n* Interesting talks\n\nThere were lots of interesting talks and too many to mention in a single blog post, but here are some honourable mentions:\n\n** Larry Hasting and the *gilectomy*\n\n\nhttps://wiki.python.org/moin/GlobalInterpreterLock\nhttps://www.youtube.com/watch?v=ph374fJqFPE\n\nThe infamous GIL has been a reason of debate for a very long time now, and many have asked for its removal.\nRemoving the GIL however is not going to happen if it breaks all existing code and current CPython semantic.\n\nLarry Hastings (one of Python core developers) gave a very good talk about a project he's been working on for the last few months.\nApparently removing the GIL is not that hard and Larry already did it in an experimental branch, however the performances are currently terrible.\n\nThe reasons are mainly related with data locality, how CPU caches work and the reference counting garbage collector currently used by Python.\nHe then discussed some possible solutions that can be used to mitigate these issues, and dived more deeply into the problems associated with them.\n\n** Pytest nodev\n\nAnother very interesting talk was about pytest-nodev (https://github.com/nodev-io/pytest-nodev).\n\nThis little project allows you to find code that solves your problem in your environment, specifying just the behaviour you need.\nIt works by simply trying to call everything all the callable objects in your environment, checking if anything has the desired behaviour.\n\nAnd it does that not just calling functions but instantiating classes, looking up in methods/properties and attributes.\nBecause this tool just calls arbitrary code it's very important to not run it on your local environment, and the author was demoing it running it in a docker container without root access.\n\nThe great thing about this project is that it has the potential to help detecting logic duplication across many projects, and there are actually plans for an online index that allows to search.\n\n** Coala\n\nCoala (https://github.com/coala-analyzer/coala) is a very interesting framework that aims to make code analysis easier for all languages.\nTwo things in particular I find interesting about this project:\n\n- it tries to re-use all existing technology, using /bears/ to interface with existing tools\n- it doesn't just report on style violations but can also act on them fixing the code itself\n\nThis project is quickly growing and could be a very useful tool to help keeping the code nice and clean.\n\n** Jupyter\n\nJupyter is the project that was known as IPython notebook, and it doesn't stop impressing me for how great it is.\n\nVisualisation of complex data has always fascinated me, and maybe the best thing I've seen about that at europython was a talk that combined jupyter, bokeh and networkx.\n\nIn just a few lines of code the speaker managed to create an interactive network using data from twitter users that tweeted about europython.\nThis graph was interactive as you could explore, zoom in and even remove nodes, getting a new graph.\n\nhttp://jupyter.org/\nhttp://bokeh.pydata.org/en/latest/\nhttps://networkx.github.io/\n\n** Pypy Reverse debugger\n\nArmin Rigo (one of Pypy authors) gave a great little demo about reverse debugging in Python.\nhttps://morepypy.blogspot.ie/2016/07/reverse-debugging-for-python.html\n\nIt was quite impressive to see how you can go back in time and set complex watch expressions.\n\nIt's somehow similar to the ELM travelling debugger: http://debug.elm-lang.org/ but it's even more impressive done in Python, since it's a lot easier to do that in language based on immutable data structures.\n\nSadly not many projects works straight out of the box with Pypy, but for the ones that do it's certainly something to try out.\n\n** LIGO and the gravitational waves discovery\n\nIn February there was a great Physics discovery done by one of the physics institute, you can read more here: https://www.ligo.caltech.edu/news/ligo20160211\n\nI'm not brave enough to try to explain the Physics behind all this, but the discovery was apparently groundbreaking and the coronation of a dream for many.\nThe impressive thing about this project is that almost everything in the chain of tools needed during this project has been written in Python and released as open source straight away.\n\nA great and inspiring way to do science and a very interesting project, that might have some important consequences.\n\n** Python at Disney studios\n\nDisney also had one of the keynotes, and similarly to the LIGO keynote, they also have an impressive use of Python in their technology stack.\nThey also use Python all over the pipeline, resorting on C++ when some extra speed is necessary.\n\n# TODO: a bit too vague maybe in this case?\nOne nice thing about the talk was the idea that even though Disney uses technology very heavily and pushing it sometimes to the extremes, none of that should be visible in the final result.\n\n** Prompt toolkit\n\nThis is a great little project that does makes it very simple to write smart command line applications, with syntax highlighting, auto completion and so on and so forth.\n\nThe list of related projects using it it's quite long and growing, and interestingly also IPython 5 is based on it, making the IPython experience a lot nicer.\nAnother great project based on the prompt tolkit is http://xon.sh/, a multi platform shell written entirely in Python.\n\n# TODO: add a link to that talk\nThere was a very lightning talk about it where the presenter told the evolution of his shell choice, exiting another shell at every step of the story, a bit like the movie Inception.\n\n* Social events\n\nEuropython organisers did a great job keeping everyone busy day and night, organising various events.\n\nThe europython mobile app was also a great way to communicate with all the attendees, and they even created a channel on Telegram (a Whatsapp alternative).\n\nThe second day I was one of the 50 lucky attendees who managed to get a ticket for the kayaking event.\nSince the venue is just along the river there was a rental place for kayaks just 5 minutes away.\n\nIt was one of the hottest day of the year (history apparently) for Bilbao but thankfully we left around 20, so at least noone got burnt.\n# add something more about this event\n\n[[./images/ice_age.jpg]]\n\n[[./images/kayak1.JPG]]\n\n[[./images/kayak2.JPG]]\n\n[[./images/kayak3.JPG]]\n\n\nI also attended the social event organised the third night of the event, in a very nice venue that looked like a theatre.\n\nThe Italian community (with some of the past and probably future europython organisers) this year was quite strong in Bilbao, one night we managed to get 30 Italians in the same restaurant.\n\n[[./images/italian.jpg]]\n\n\n* Python present and future\n\nThere is an ever growing interest in big data and data science, with topics like machine learning and neural networks creating more and more interest.\n\nIt was also nice to see that the scientific community overall not only embraced Python as their language of choice,\nbut also is the /avant guarde/ for Python3 adoption, as this official statement about it claims:\n\nhttps://python3statement.github.io/\n\nAnother big thing (as the schedule can argument) is asyncio and all the ecosystem around it.\n# TODO: this is already written also above, try to merge\nAsyncio is not a framework but more of a toolkit for asynchronous code, and even projects like Twisted can potentially use that as foundation on top of that.\n\n* Conclusion\n\nOverall the conference was a great success from my point of view, and I would encourage everyone to attend in the upcoming .\n\nThe only \"complaint\" might be that not all talks were well prepared or well presented, which is a shame since sometimes the topics would have been really interesting.\n\nI sadly could not stay over the weekend for the sprints but there were some very interesting projects to work on, and I was told it went quite well.\n\n* References\n\n** TODO add all the links to talks etc and just reference them from the actual content\n\nhttps://ep2016.europython.eu/en/\n\n(you can see the schedule here
