Sessions at Los Angeles Ruby Conference 2012 with slides

Saturday 4th February 2012

• Metrics-Driven 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:

  • Find CPU-intensive hotspots
  • Measure memory and object allocation
  • Monitor query count and duration
  • Isolate data-store bottlenecks

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

• Quit Your Job. Srsly.

  by Shane Becker

  "The best minds of my generation are thinking about how to make people click ads." - Jeff Hammerbacher http://buswk.co/eCdfFp

  We can rewrite Jeff's quote like this: "The best programmers of my generation are working on solutions to problems that do not matter."

  The crux of it is you are better than your job. You have a greater potential than your job is realizing. You can do more than you think. You are worth more than your job is paying you. You can make the world a better place.

  You don't have to be limited to building mobile/geo-based/social/ad-driven/gamification-influence/fully-buzzword-compliant bullshit to get people to buy things they don't need while giving up more privacy to corporations and becoming less happy in the process.

  You're better than that. Quit your job. Build your dreams. Change the world. Srsly.

• Designing Hypermedia APIs

  by Steve Klabnik

  Rails did a lot to bring REST to developers, but its conception leaves the REST devotee feeling a bit empty. "Where's the hypermedia?" she says. "REST isn't RPC," he may cry. "WTF??!?!" you may think. "I have it right there! resources :posts ! What more is there? RPC? Huh?"

  In this talk, Steve will explain how to design your APIs so that they truly embrace the web and HTTP. Just as there's an impedance mismatch between our databases, our ORMs, and our models, there's an equal mismatch between our applications, our APIs, and our clients. Pros and cons of this approach will be discussed, as well as why we aren't building things this way yet.
