Managing multiple SSH identities
Here at Imaginary we maintain our own git repositories internally with the help of the invaluable utility, Gitolite. This works well for us. However, in some cases, our clients have their own repositories that we must interact with. The problem arises when the client repositories reside on a third-party service ... -
Integration of Backbone.js with Tastypie
I recently started learning more about backbone.js as a way to create richer app-like experiences on the web without the kludge that results from creating DOM elements in jQuery. I bought all three PeepCodes on the topic and have watched them all now a few times (they are densely packed with good material). PeepCode Screencasts: backbone.js basics backbone.js interactivity backbone.js persistence We have been doing more and more of not only these richer app-like user interfaces on the web, but also API-backed iOS apps that extend the reach and functionality of the web application. Therefore, something like backbone.js just makes sense as we can share the API for both the web application as well as the iOS app. When I first got started, it became obvious to me pretty quickly that backbone.js shipped with a lot of default assumptions about how the REST API worked (predicted url paths, data structures, and so on). I am a big fan of Tastypie, in fact, all of us at Eldarion are. It's dead simple to extend and customize, enabling us to quickly and easily add APIs to sites. There were a couple of small things that didn't work out of the box with … -

Whiskers and buildout.sendpickedversions
Last year I participated in a deployment knowledge sharing session and I started implementing changes at my company pretty soon after. The result is that we are using Puppet for some parts of our server configuration. We also added Munin to our monitoring toolset (and I used Puppet to deploy Munin and manage its configuration). But an important piece that was still missing in our setup was an overview of which packages we use in the buildouts of our clients and more specifically which version each client uses. Apparently I was not the only one that wanted to have such an overview: Jukka Ojaniemi created Whiskers (PyPI, GitHub) and released version 0.1 in December 2011. Whiskers is a Pyramid application and it is intended to be used in combination with the buildout extension buildout.sendpickedversions (PyPI, GitHub). Setting up Whiskers is very simple (see the Whiskers README for details) and since the data is stored in an SQLite database there is little infrastructure needed. The buildout side is even less work, since you only have to add the following: [buildout] ... extensions += buildout.sendpickedversions buildoutname = <buildout-name> whiskers-url = <whisker-server-url>/buildouts/add And the result after modifying several buildout configurations is a nice … -
Asynchronous email delivery with Django, Amazon SES, Celery and Supervisord
A few weeks ago, I released a simple Django app to manage models for simple newsletters. The package itself is blatantly useless if we do not use it on a project that integrates with other parts, so I created a fully-equipped system that can create propaganda, assign it to subscribers and queue it ready to be sent whenever I need to. The architecture First, I have been using Amazon SES for a while to send newsletters to customers, both in-house and for clients and third-parties. It removes the hassle of maintaining SMTPs, email server management, network configuration, and meeting rigorous Internet Service Provider (ISP) standards for email content. So we will take profit of all those advantages, and make our life more simple and enjoyable. Second, we want a smooth and efficient delivery through concurrent background tasks, seamless for the user and detached from the front-end business logic. Whenever we press the "send" button we expect the system to return a confirmation response immediately — regardless of what's happening in the background — instead of getting the request frozen, waiting too much time for the email queue to be emptied and ending up with a web server timeout response. Celery … -
Gerbi CMS
Gerbi CMS (nee django-page-cms) is a multilingual content management system written in Python and based on the Django web framework. It's currently my favourite CMS software and use it for a number of web sites I administer. I'll be giving a talk about Gerbi CMS at the next OCLUG and OPAG meetings resembling this article. -

Mozilla Webdev’s Beer and Tell: April 16, 2012
In case you missed last month’s blog post, a Beer and Tell is a monthly Mozilla Webdev gettogether involving cool hacks and malted beverages. We try to structure it like a series of lightning talks and — because all work and no play makes web developers go crazy — some of us have a beer during. Some of the East Coast folks drink scotch instead, but it’s OK because it’s after 5pm in Toronto by then. We didn’t record this Beer and Tell (my bad!), but I thought I’d share what was presented. It was pretty gaming-focused and quite cool. Django Stats Admin Created by Michael Kelly, this nifty little app allows you to visualize any of your Django models with datetime fields in the Django Admin. It uses the flot JS library to create pretty charts and lets you specify date ranges. Michael’s currently working on abstracting the app out into a library that can be used with any Django app. Lisp -> DCPU-16 Compiler James Long, our resident Lisp champion, started off by telling us about 0x10c and the DCPU-16 assembly language in the game. It’s pretty cool stuff for gamers who are language geeks too. Of course, … -
Yet another tutorial for building a blog using Python and Django - part 5
In this instalment I’ll be showing you how we can make our blogging engine a little nicer to look at by adding some CSS and images, as well as expanding on Django’s templating system. First of all, let’s add some CSS to our blog. When developing a web app with Django, you should place static files such as stylesheets and images in a folder inside your app (not project) folder called static. My project is called DjangoBlog, and my app is called blogengine, so all my static content should go in DjangoBlog/blogengine/static/. Here’s the stylesheet, which I’ve saved as style.css: body { background-color: #f0f0f0; font-family: Arial, Helvetica, sans-serif; } #main { width: 800px; height: 100%; margin: 50px auto; } ul#pageList { margin: 0px; padding: 10px 0px 10px 0px; } ul#pageList li { display: inline; margin-right: 10px; font-size: 18px; } .post, .page { width: 600px; padding: 20px; margin-bottom: 20px; background-color: #ffffff; } In the same folder, I have a PNG icon for an RSS feed, and if you had some JavaScript files you wanted to use (such as a copy of jQuery), you would put them here too. Note that there’s nothing to stop you creating subfolders within /static, and in … -
Ginger Tech Stack

Ginger Tech Stack
Click here to see this post in it's natural habitat and to watch and leave comments. For our latest product, Ginger, we wanted to marry the real-time functionality we needed with the traditional Django stack we know and love. After some false starts and falling on our faces in the beginning, we ended with a stack we’re happy with and think will serve us well moving forward. Back-end This is our bread-and-butter. It’s Django and PostgreSQL running with Gunicorn behind Nginx. The biggest difference between this and your typical Django site is that it mainly serves as a REST API consumed by the front-end. We are using traditional Django views in a few places like login, logout, and user profiles, but the rest of the views are handled by the front-end. Using Django, we were able to quickly build the nuts-and-bolts parts of our site that didn’t require any special real-time functionality. A few of the important libraries we’re using: tastypie for building the REST API haystack backed by solr for search celery backed by Redis for task queueing misaka and pygments for text formatting easy-thumbnails and PIL for image thumbnailing Front-end Our front-end uses Backbone.js to handle most of … -
Django 1.4 admin image issues with S3 backed static files
This is going to be kind of obscure, but hopefully it helps someone. My current default setup for using S3 backed static files for Django broke when I upgraded to 1.4. The affect was that the admin media paths had been URL encoded so "/" was replaced with "%2F". https://s3.amazonaws.com/bucket_name/admin%2Fcss%2Fbase.css This caused images referenced in the css to fail because relative paths were interpreted (in Chrome at least) as being relative to the last unescaped slash instead of to /css. This also caused horizontal filters to fail as well. The Source The problem was exposed by a change in Django 1.4. Since Django no longer uses ADMIN_MEDIA_PREFIX, the storage system gets involved in creating the urls for the admin site media. I had been using a combination of the S3 Python library and django-storages. Django storages is basically doing the right thing, though it does have an opportunity to unescape the paths it gets from S3. The escaping itself is contained S3 library for Python, but I elected to take a different route to work around it. Solution My solution was to bypass the problem and switch S3Boto backend for django-storages. I have been using Boto for SES based email … -
Python Deployment Anti-Patterns
Deploying web applications is hard. No shiny continuous deployment talk and no DevOps coolness can change that. Or to use DevOp Borat’s words: “Is all fun and game until you are need of put it in production.“ There are some mistakes I see people doing again and again so I’d like to address them here. This article is also laying ground for the second part where I’ll describe the way we deploy Python applications. My background Before I start preaching, let me tell you a bit about me and what I do in order to give you some perspective from which I’m writing. I work for a German web hoster and domain registrar. And I’m deploying Python based applications all the time. Most parts of our infrastructure are built using Python. And those that aren’t, will be eventually. The sizes range from tiny glue to mission-critical APIs. We have legacy Pylons, new Pyramid, some Django and a lot of Twisted apps. And everything is seasoned with a hint of Celery. So if I say “application”, I don’t mean just some Django CRUD front end. Python lives in all layers here. And all layers have to be deployed somehow. Deploying so … -

First presentation of Skeltrack
I spent the first half of this week in the beautiful city of Évora, where I was born. The occasion was the Semana da Ciência e Técnologia (Science and Technology Week) of the University of Évora to which I was invited. I also ended up giving the organization a hand by asking Thomas Perl (the restless mind behind gPodder) and Lucas Rocha (well known GNOME developer now using his powers in Mozilla) who kindly accepted. Having participated in the organization of events during the University, I’m always happy to see these initiatives taking place. It was also great to spend a couple of days with the folks at my University and meet with old friends. About the talks, Thomas gave an overview of gPodder and the infrastructure used to manage the project. Lucas gave a really nice talk about what Mozilla is, what it does and why you should care; because of it, I ended up installing Firefox Mobile nightly build for Android and it has improved a LOT. My friend Luís Rodrigues (no blog because he’s a badass) talked about CERN, where he works. What an amazing place! He talked about how much CERN uses Python and Django to …
