###The ROSSConf project, or: helping Open Source help Open Source

Last April Saturday ROSSConf Vienna took place. Sixty registered participants, some loose canons, 5 projects, 6 maintainers, 8-ish team members, 1 baby all in one coworking space. Here's what happened.

####In the beginning October last year, at arrrrcamp, I came up with the concept for ROSSConf. Having attended 1001 tech conferences (I haven't kept count) I concluded that I'm always missing something. I found myself listening to a talk and wishing I could contribute to the project discussed but the internet connection wasn't sufficient for cloning the repo, nor was there time to hack on the project as the next talk was about to start. And, I figured, I'd need some time to get into the project and the contributing etiquette before being able to contribute.

Zero downtime deploys with gunicorn

Below are the actual files we use in one of our latest applications at Agora Games to achieve zero downtime deploys with gunicorn. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Salient points for each file:

• gunicorn.py: The pre_fork function looks for gunicorn's old PID file in the proper file and sends the proper QUIT signal to the old process once the new process is running.
• sv-gunicorn-run.jinja: This is the runit template we use in our Salt-managed infrastructure for handling the application process management. You could just as easily convert this to a non-templatized version.
