Montréal-Python 45: Cacophonic Dumpling

Montreal Python - Mon, 05/26/2014 - 15:00

Good news, everybody! All the Python people will shortly converge to town. We will seize the opportunity to invite a broad audience --all of you Pythonistas in town-- to our good old monthly meeting.

We are pleased to join forces with DevOps Montréal to offer a great event.

We will meet at Radialpoint on Bleury street, just a few steps away from Palais des Congrès.

As usual, the meeting extends into an evening at our favourite place, celebrated brewpub Bénélux!

Main presentations:

Joseph Hall from SaltStack: Configuration management - finding the tool to fit your needs

In ye olde days of web, a company might manage a handful of servers, each manually and frequently tuned and re-tuned to the company's needs. Those days are gone. Server farms now dominate, and it is no longer reasonable to manage individual servers by hand. Various configuration management tools have stepped in to help the modern engineer, but which to choose? It is not an easy question, and canned pitches from sales people are unlikely to take into account all of your variables. This talk will attempt to discuss The Big Four objectively, and from what angles they approach the task at hand.

Yannick Gingras from Facebook: Scaling the Facebook Cache Infrastructure with Python

Facebook leverages in-memory data stores extensively. Even though caching is a conceptually simple service, several problems inherent to our scales make the deployment of our in-memory data store particularly interesting and challenging.

Facebook's real time in-memory data store includes two major services: Memcache, a look aside key-value store, and TAO, a read-through and write-through graph aware cache that supports structured queries. Both daemons run on thousands of dedicated servers.

In this talk, I will give an overview of the problems that we face deploying cache services that answer over a billion queries per second while maintaining sub-millisecond response time. I will describe the strategies that we use to mitigate them and since Python is a critical piece of the puzzle, I will highlight some of the areas where we use it. I won't spare you from our war stories and the sense of scale could feel crushing at times but I will do by best to keep it entertaining.

Alex Gaynor from Rackspace: Code Review for Open Source

Code review is fun. This talk will explore the benefits of code review, and a number of different workflows to enable it in both open source and commercial software development.

Special presentation:

Panel: Python 3 adoption and barriers

Python 3.4.0 was just released! Many Python developers are enthusiastic about the cleanups in the language and standard library, but many others suffer from missing features in the Python 2 line. What’s the status of the migration? How are the core developers in tune with the larger community? Invited representatives, including CPython core developer Nick Coghlan and CPython and PyPy core developer Alex Gaynor will share their experience and answer questions from the audience.

Call for Speakers, Montréal-Python 47: Grandiose Heuristics

Montreal Python - Sun, 05/25/2014 - 23:00

Summer is here, and we all want to walk around in sandals, relax in the sun and drink a nice cold beer on a terrasse. But before, we should all give her.

We especially love to hear from new speakers. If you haven't given a talk at Montréal-Python before, a 5 or 10 minute lightning talk would be a great start, but we also have slots for 10 to 40 minutes talks!

Some topic suggestions:

  • Give a beginner's introduction to a Python library you've been using!
  • Talk about a project you're working on!
  • Show us unit testing, continuous integration or Python documentation tools!
  • Tell us about a Python performance problem you've run into and how you solved it!
  • The standard Python library is full of amazing things. Have you learned how multiprocessing or threading or GUI programming works recently? Tell us about it!
  • Explain how to get started with Django in 5 minutes!

We're always looking out for 10 to 40 minutes talks, or a quick 5 minutes flash presentation.

If you discovered or learned something that you find interesting, we'd love to help you let others learn about it!

Command-Line Cloud: rss2email

Linux Journal - Thu, 05/22/2014 - 12:05

In my last article, I started a series called Command-Line Cloud. The intent of the series is to discuss how to use the cloud services we are faced with these days without resorting to a Web browser. I spend most of my time on the command line, so that's where I'd most like to interface with cloud services. more>>

Siege Your Servers!

Linux Journal - Mon, 05/12/2014 - 16:59

Setting up Web servers is fairly simple. In fact, it's so simple that once the server is set up, we often don't think about it anymore. It wasn't until I had a very large Web site rollout fail miserably that I started to research a method for load-testing servers before releasing a Web site to production. more>>

Android Candy: Waze

Linux Journal - Thu, 05/08/2014 - 16:08

I have a love/hate relationship with Waze. The idea of peer collaboration regarding traffic, combined with the technology to accomplish it on an enormous scale is truly amazing. Yet, every time I've used Waze myself, it's been an exercise in frustration. It has insisted I turn left off a bridge, and then it refused to reroute me when I didn't. more>>

Montréal-Python 46: Electronic Frontier

Montreal Python - Mon, 05/05/2014 - 23:00

It is with great pleasure that we invite you to the 46th edition of Montreal Python's meetup.

We have the great privilege to host 2 talks on operating systems. Frédéric Harper will present Firefox OS for mobile and Jacob Cook will present ArkOS for the Raspberry Pi.

Following the panel discussion on Python 2 - 3, Rory Geoghegan from Ecometrica will present a lighting talk in unicode. Followed by Davin Baragiotta from Savoir-Faire Linux will talk about How to deploy an application on Heroku based on the Heroku 101 workshop presented at PyCon. Finally George Peristerakis will talk about career advice to new software developer graduates.

Please register on Eventbrite, before Sunday noon, in order to help us better organize the event.

Flash Presentations:
  • Davin Baragiotta : Déployer une application web sur Heroku
  • George Peristerakis: A guide through the modern developer career landscape.
  • Hadrien David: Key versioning caching.
Main presentations:
  • Frédéric Harper - Firefox OS: HTML5 to the next level If you are like me, your spectrum of interest is large when it comes to technology. You may be a Python developer, but that does not mean you have not any interest in HTML, and it’s a good coincidence as it’s the foundation of my presentation. In this talk, Frédéric Harper will show you how you can use HTML5 with the power of JavaScript to build amazing mobile applications as to brush up what you previously published. Learn about the open web technologies, including WebAPIs, and tools designed to get you started developing HTML apps for Firefox OS, and the web.

  • Jacob Cook - ArkOS arkOS is an operating system and front-end software stack dedicated to setting up easy self-hosted servers on inexpensive hardware like the Raspberry Pi. arkOS' flagship tool Genesis manages all aspects of a system and its software, and is based entirely in Python. Lead programmer Jacob Cook will walk through the software and its frameworks, how they work, and why self-hosting in principle is becoming more and more important.

  • Rory Geoghegan: Unicode is ∂© in python 2, but way better in python 3 This talk will try to explain the decisions about encoding and unicode in python 2 and the splitting of strings in python 3 into bytes and unicode strings.

Python Workshop : Basic Introduction for Psychology Researchers

Montreal Python - Wed, 04/30/2014 - 15:00

Sooner or later, psychology researchers have do deal with data. They collect, transform or analyse data as other scientists do. Then, why not embrace Python strength as more and more researchers do with the help of the Scientific Python's stack? Montréal-Python is here to help start this journey from the beginning, helping to put hands on the Python language.

Montréal-Python is proud to announced its first workshop organized in collaboration with INPSYCH Workshops, Department of Psychology, Concordia University.

Unfortunately, for logistic reasons, this workshop is not open to all. Registration has been communicated by INPSYCH Workshops. This workshop is designed for psychology students at all levels. No programming experience necessary.

At the end of this workshop, students will have learn to:

  • explore by themselves Python's potential through experimentation and introspection in the interpretor
  • master the basic notions : types, fonctions, conditionnals, iterations...
  • write a script
  • import Python's power

For those who will attend : Here's the complete content of the workshop.

The workshop will be:

  • Tuesday, the 18th of March 2014
  • from 6:00 PM to 9:00 PM
  • room SP-157 of Concordia University

Bring your laptop or pair up with someone else.

You'll need Python running on your computer. It's also recommended to have IPython installed.

Generally speaking, if you want to have fun with the code in Montréal-Python workshops without loosing your time with configuring your machine and if you want a guaranteed support by the assistants, do yourself a favor and get a developer workstation on Ubuntu by following these simple steps.

If you need help to setup your development environment, we'll be there to help before the workshop, starting at 5:30 PM.

See you soon!

BirdCam, Round Two

Linux Journal - Tue, 04/29/2014 - 11:26

In the October 2013 issue, I described the hardware and software I used to create my "BirdTopia Monitoring Station", more commonly called BirdCam. If you've been visiting BirdCam recently, which a surprising number of folks have been doing, you'll notice quite a few changes (Figure 1). In this article, I describe the upgrades, the changes and some of the challenges along the way. more>>
