  Scaling: Rails Security

  Even though Ruby on Rails introduces a lot of best practices to the developer, it is still quite easy for an imprudent programmer to forget that every web application is a potential target. Web application attacks like Cross Site Scripting or Cross Site Request Forgery are very popular these days and every Rails developer should have an idea about the different possibilities that his application presents to an attacker.

  This talk will cover most of the common web application vulnerabilities like Cross Site Scripting and Cross Site Request
  Forgery, SQL and Code injection, and deployment security and how they apply to Rails. Further Ruby on Rails specific issues like Rails plugin security, JavaScript/Ajax security, and Rails deployment security will be examined and best practices introduced.

  Bart ten Brinke & Willem van Bergen

  Tuning your rails application - to measure is to know

  http://www.nedap.com/

  Bart ten Brinke and Willem van Bergen have more than 10 years of rails experience between them.
  Willem van Bergen is known for his work at Floorplanner.com, while Bart ten Brinke is one of the founders of Moves from Nedap healthcare.
  Together they wrote the request-log-analyzer gem to cater their own performance information needs.
  Today they are working together as Railsdoctors.com, providing Rails performance and security consultancy.

  In their talk, Bart and Willem will discuss an often neglected part in BDD: performance.
  Because performance doesn’t matter, until it does.

  We will explain how to prepare for the time when the shit does hit the fan, so you won’t be caught with your pants down.
  How to drill down to the core of the problem, and then how to solve it.
  In performance there is no such thing as a silver bullet, but after this talk you will know which tools should be in your toolbox.
  And more important: how they should be used.
