  • Becoming a Ruby Gemcutter

    by Nick Quaranto

    Welcome to the world of Ruby: where the gems are deep, rough, and rarely documented! No need to fear though, in this presentation you'll learn what a RubyGem is, how they're used in Rails and Ruby applications, and of course, how to make your own. You'll see just how easy it is to share your code with others in the Ruby universe, and why creating packages is a joy instead of a burden thanks to the tools and ecosystem of RubyGems.

    At 11:00am to 12:00pm, Thursday 12th January

    In Cypress, Kalahari Waterpark Resort Convention Center

  • Metrics-Powered Ruby/Rails Performance

    by Jeff Casimir

    Ruby can't scale. Tell that to LivingSocial, GroupOn, Gowalla, Sony, and the rest of our community pushing millions of requests per day. Scaling an application isn't about piling up hardware and dropping in the newest database fad, it's the combination of design and refinement.

    In this session, we'll look at refining Ruby code using tools to:

    • Measure memory and object allocation
    • Find CPU-intensive hotspots
    • Isolate data-store bottlenecks
    • Evaluate code complexity

    This is not about info-porn. It's about finding the 1% of your code that, through optimization, can dramatically improve performance.

    At 3:35pm to 4:35pm, Thursday 12th January
