Alejandro Guirao Rodríguez - Extending and embedding Ansible with Python [EuroPython 2015] [23 July 2015] [Bilbao, Euskadi, Spain] [Slides here][1] :-) [Ansible ][2] is the _new cool kid in town_ in the configuration management world. It is easy to learn, fast to setup and works great! In the first part of the talk, I will do a super-fast introduction to Ansible for the newcomers. If you are a Pythonista, you can hack and leverage Ansible in many ways. In the second part of the talk, I will describe some options to extend and embed Ansible with Python: - Embedding Ansible with the Python API - Extending Ansible: creating modules, dynamic inventory scripts and plugins Previous experience with Ansible is advised in order to get the most of this talk, but beginners to the tool will also get an overview of the capabilities of this kind of integration.

Romain Guillebert - PyPy and the future of the Python ecosystem [EuroPython 2015] [24 July 2015] [Bilbao, Euskadi, Spain] Python has a great versatile ecosystem but the competition is getting better, this talk is about how Python can keep up with these new languages and where PyPy fits into this. Recently we've seen the rise of new technologies like Go, Node.js and Julia, those have the ability to build an ecosystem on a clean slate and thus be better than Python in some aspects. What would it take to be as good as those technologies on those aspects without loosing all the things we love about Python ? This talk will describe my perfect future where Python keeps getting better, gets to keep it's great set of libraries and where PyPy fits in that future.

Wojciech Lichota - Continuous Deployment for webapps based on Django [EuroPython 2015] [24 July 2015] [Bilbao, Euskadi, Spain] When you see users starting to use your feature, you feel very proud and fulfilled. So why feel this only once every few weeks, why not feel it every day? In this talk I will show how we changed our workflow to automate deployment of code changes to production every time a feature is ready - sometimes even few times per day. I will present how to successfully combine open-source tools like Git, Jenkins, Buildout, Fabric, uWSGI, and South, in order to simplify the process and make it more reliable. I will discuss challenges that we faced implementing this workflow in a real project based on Django and how we resolved them. During this talk you will gain the knowledge required to implement Continuous Deployment in your own project.

Piotr Dyba - with modern_peripherals: Python and Flask [EuroPython 2015] [20 July 2015] [Bilbao, Euskadi, Spain] with modern_peripherals: Python and Flask Auto-scrolling sites, glance-following ads, and gesture friendly web pages are coming! Over the last few years three products emerged that enable interaction with computer in a new way: Myo Armband, Leap Motion Controller and EyeTribe. The Myo Armband is a device that uses the electrical activity in your muscles to wirelessly control your computer, phone, and tablet, which is especially useful when your hands are "tied" or dirty. This device will be used to navigate through the presentation. The Leap Motion Controller tracks both hands in front of the screen. From a web developer’s perspective, both devices allows us to use gestures, previously restricted to touch devices, on desktops. EyeTribe is an affordable eye-tracking device. The talk will briefly cover setting up SDKs and python wrappers, and then focus on possible uses in daily life, business and, of course, web app development. Code examples will be included. In addition, the trade-offs between processing this new type of input data in the client versus processing input on the server will be discussed.

Philipp Mack - Python in the world of retail and mail order [EuroPython 2015] [24 July 2015] [Bilbao, Euskadi, Spain] At Blue Yonder a lot of different python packages, provided by the community, as well as our own self-written packages, are used in order to provide flexible solutions to our problems. In this talk I'll present a walkthrough of a generic python application example for demand and purchase order quantity calculations, putting together those packages in an orderly way. The example will feature real world problems derived from hands-on experience with our retail and mail order customers. Additionally the talk addresses the subjects of testing, configuring, parallelising and deploying the code. Packages used in this talk are : - pytest http://pytest.org/latest/ - voluptuous https://github.com/alecthomas/voluptuous - redis https://pypi.python.org/pypi/redis/ - SciPy http://www.scipy.org/ - scikit-learn http://scikit-learn.org/stable/ - pandas http://pandas.pydata.org/

Marco Buttu - Lessons learned about testing and TDD [EuroPython 2015] [21 July 2015] [Bilbao, Euskadi, Spain] One day our software will go in production, and so shortly we will pay dearly for our youthful mistakes. Without regression tests, we will be in deep trouble. If we have regression tests, but we did not have performed TDD, we should probably increase the effort in bug fixing and maintenance, since we do not have enough code coverage and our tests come out complex. By retracing the author youthful mistakes, we will see a complete development workflow, from the user story to the low-level tests, in order to highlight the differences between functional, integration and unit tests, the best practices, and the lessons learned by the author during the development of the [Sardinia Radio Telescope][1] control software.

Alexander Sibiryakov - Frontera: open source large-scale web crawling framework [EuroPython 2015] [20 July 2015] [Bilbao, Euskadi, Spain] In this talk I'm going to introduce Scrapinghub's new open source framework [Frontera][1]. Frontera allows to build real-time distributed web crawlers and website focused ones. Offering: - customizable URL metadata storage (RDBMS or Key-Value based), - crawling strategies management, - transport layer abstraction. - fetcher abstraction. Along with framework description I'll demonstrate how to build a distributed crawler using [Scrapy][2], Kafka and HBase, and hopefully present some statistics of Spanish internet collected with newly built crawler. Happy EuroPythoning! [1]: https://github.com/scrapinghub/frontera [2]: http://scrapy.org/

Benoît Calvez - Python and elasticsearch 101 [EuroPython 2015] [20 July 2015] [Bilbao, Euskadi, Spain] Before its first major version, Elasticsearch was only used as a "secondary" database, and search engine. The releases added a snapshort/restore feature, making it a great full featured database This talk will focus on how we integrate Elasticsearch into our stack, and the multiple usage we make of it: from storing business events to IOT devices metrics.

Sebastian Neubauer - A Pythonic Approach to Continuous Delivery [EuroPython 2015] [22 July 2015] [Bilbao, Euskadi, Spain] Software development is all about writing code that delivers additional value to a customer. Following the agile and lean approach this value created by code changes should be continuously delivered as fast, as early and as often as possible without any compromise on the quality. Remarkably, there is a huge gap between the development of the application code and the reliable and scalable operation of the application. As an example, most of the tutorials about web development with Flask or Django end by starting a local “dummy” server, missing out all the steps needed for production ready operation of the web service. Furthermore, as there is no “rocket science” in-between, many proposals to bridge that gap from both sides, operations and developers start with sentences like: “you just have to...”, a clear indication that it will cause problems later on and also a symptom of a cultural gap between developers and operations staff. In this talk I will go through the complete delivery pipeline from application development to the industrial grade operation, clearly biased towards the “DevOps” mindset. Instead of presenting a sophisticated enterprise solution, I will outline the necessary building blocks for continuous delivery and fill them up with simple but working poor man's solutions, so that it is equally useful for professional and non-professional developers and operations engineers. After the talk you will know how to build such a continuous delivery pipeline with open-source tools like “Ansible”, “Devpi” and “Jenkins” and I will share some of my day-to-day experiences with automation in general. Although many of the concepts are language agnostic I will focus on the ins and outs in a python universe and outline the pythonic way of “get this thing running”.
