Security is Broken: Understanding Common Vulnerabilities
The Internet is built on technology that was never meant to work together. Basic features in seemingly simple and innocuous technologies, such as XML, resulted in these technologies being insecure. In this session we’ll talk about how attackers exploit well known vulnerabilities like XSS, XXE, and CSRF and how to make more secure software by avoiding similar decisions that resulted in these exploits.

How to Performance
Understanding performance output can feel like reading tea leaves. It makes sense to a few people, but many of us are left in the dark; overwhelmed and frustrated by the data. On top of that there are a ton of performance tools to choose from; StackProf, RubyProf, AllocationTracer. Where do you even start?
While working on speeding up integration tests in Rails source, I learned that the key to improving the performance of Ruby code is having a baseline, not relying on one profiler and understanding the advantages and limitations of your tools. By utilizing these methods, integration tests are now 3 times faster than they were in Rails 4.2.0, with more improvements being made every day.
In this talk we will not only look at how to read performance output, but when and how to use the right profilers for the job. We’ll discuss a variety of methods and techniques for benchmarking and profiling so you can get the most out of any performance tool.

Breaking Down the Barrier: Demystifying Contributing to Rails
Contributing to Rails for the first time can be terrifying. In this lab I’ll make contributing to Rails more approachable by going over the contributing guidelines and technical details you need to know. We’ll walk through traversing the source code with tools such as CTags, source_location and TracePoint. Additionally, we’ll create reproduction scripts for reporting issues and learn advanced git commands like bisect and squash. At the end of this session you’ll have the confidence to fix bugs and add features to Ruby on Rails.
CRUD! Dear Active Record, It’s Not You, It’s Me
The magic of ActiveRecord database interactions is easy to rely on and allows us assume it knows best. Without a solid understanding of how ActiveRecord translates into MySQL, however, significant issues can arise. This is particularly true with large data sets and complex model relationships. My talk explores an example for each CRUD function and shows how these queries can result in MySQL timeouts, memory issues or stack level too deep errors. The examples will examine the consequences of chaining large datasets, uses for Arel, and how to avoid encountering major problems and most importantly, how these queries can be rewritten to run more efficiently.
