• From Rails Rumble to 50,000,000 results

  by Mikel Lindsaar

  StillAlive.com was born from the 48 hour intense 2010 Rails Rumble and has grown! Having recently passed our 50,000,000th site result, this talk discusses the real world challenges and optimisations required to take a code base born from the fires of YAGNI to a production system.

  This talk isn't about how you can scale from 0 requests to 500 billion requests per microsecond, but give a practical view to some of the performance problems we faced as the application steadily grew from a hack job into a functioning system.

  The journey will go through the mistakes we made, challenges faced and real world optimisations discovered, including some tricks we learnt along the way from concurrent index creation to using the ZeroMQ messaging framework with Rails

• Chanko - How Cookpad safely releases multiple feature prototypes for test segments of their 15 million engaged users

  by Kenta Murata

  Chanko provides a simple framework for rapidly and safely prototyping new features in your production Rails app, and exposing these prototypes to specified segments of your user base.

  With Chanko, you can release many concurrent features and independently manage which users see them. If there are errors with any chanko, it will be automatially removed, without impacting your site.

  Chanko was extracted from Cookpad.com where the team uses it daily to test new features live, in production, on the largest Rails site in Japan which serves 500 million page views a month to a user based of over 15 million highly engaged uses.
