These slides are from my caching talk at the Fog City Ruby meetup on Tuesday, June 13th, 2017
"Site's down. Out of memory errors. Identified the problem, fixed it, wrote a juicy post mortem. Come learn how to NOT implement caching in your Rails app. I'll talk about the various types of caches, forming the proper cache keys, and increasing site performance. Who doesn't love a classic 10x speedup?"
