Overview: Join speakers from Yelp & GitHub at Yelp HQ for two shorter style talks this time around. Jonah Berquist will give a talk about GitHub's triggerless online schema change tool, gh-ost, and Jenni Snyder her talk previously named "WE'RE NOT YELLING AT YOU", about using automation and tooling to prevent resentment between DBAs & Developers. Bio: Jonah is the Engineering Manager of the Database Infrastructure team at GitHub. His previous job was as a Senior DBA at Twitter and he had humble beginnings working as a remote DBA for a variety of customers at Blue Gecko. He enjoys looking at graphs and writing scripts to do his job for him. Jenni has been a MySQL DBA for over ten years, and spending the last six here at Yelp. She loves how easy it is to start with MySQL, the performance and tuning options, and the Community around it that welcomes new members. Her favorite aspects of MySQL DBA work are finding & eliminating bottlenecks, InnoDB tuning, optimizing slow queries, eliminating deadlocks, and helping developers. 6:30 - 7:00 -- Doors open/general socializing & food 7:00 - 7:15 -- Intro/announcements 7:15 - 8:00(ish) -- Main presentation 8:00 - 8:30 -- General discussion/Q&A/networking/etc. 8:30ish -- post-event socializing... aka beers someplace nearby Sponsors: Yelp (http://yelp.com/) has been changing the nature of how people share local knowledge and find out about what's going on in their city and beyond since 2005. We're one part community, one part local city guide, with an opinion on everything from mechanics and martini bars to dentists and dining, and everything in between. Doesn't that sound like something you'd want to be involved in?
