Once a month, web developers from across the Mozilla Project get together to trade and battle Pokémon. While we discover the power of friendship, we also find time to talk about our side projects and drink, an occurrence we like to call “Beer and Tell”.
Michael Kelly: gamegirl
Our first presenter, Osmose (that’s me!), shared a Gameboy emulator, written in Python, called gamegirl. The emulator itself is still very early in development and only has a few hundred CPU instructions implemented. It also includes a console-based debugger for inspecting the Gameboy state while executing instructions, powered by urwid.
Luke Crouch: Automatic Deployment to Heroku using TravisCI and Github
Next, groovecoder shared some wisdom about his new favorite continuous deployment setup. The setup involves hosting your code on Github, running continuous integration using Travis CI, and hosting the site on Heroku. Travis supports deploying your app to Heroku after a successful build, and groovecoder uses this to deploy his master branch to a staging server.
Once the code is ready to go to production, you can make a pull request to a production branch on the repo. Travis can be configured to deploy to a different app for each branch, so once that pull request is merged, the site is deployed to production. In addition, the pull request view gives a good overview of what’s being deployed. Neat!
Peter Bengtsson: django-screencapper
Friend of the blog peterbe showed off django-screencapper, a microservice that generates screencaps from video files using ffmpeg. Developed as a test to see if generating AirMozilla icons via an external service was viable, it queues incoming requests using Alligator and POSTs the screencaps to a callback URL once they’ve been generated.
A live example of the app is available at http://screencapper.peterbe.com/receiver/.
tofumatt: i-dont-like-open-source AKA GitHub Contribution Hider
Motorcycle enthusiast tofumatt hates the Github contributor streak graph. To be specific, he hates the one on his own profile; it’s distracting and leads to bad behavior and imposter syndrome. To save himself and others from this terror, he created a Firefox add-on called the GitHub Contribution Hider that hides only the contribution graph on your own profile. You can install the addon by visiting it’s addons.mozilla.org page. Versions of the add-on for other browsers are in the works.
Fun fact: The power of friendship cannot, in fact, overcome type weaknesses.

See you next month!
