Roy Tomeij is co-founder of Ruby consultancy 80beans in Amsterdam, where he takes care of front-end architecture using an agile approach. He loves front-end meta languages like Haml, Sass & CoffeeScript because they are DRY, produce quick results & lead to better maintainable code. Roy has seven years of professional front-end experience in Rails projects.

    Modular & reusable front-end code with HTML5, Sass and CoffeeScript

    A lot of Ruby developers use Rails for their everyday projects. Often they toy around with front-end themselves or outsource it, ending up tangled in a web of css-all-over-the-place.

    Keeping your front-end code clean is hard. Before you know it you're suffering from CSS specificity issues and not-really-generic partials. Find out how to keep things tidy using the HTML5 document outline and modular Sass & CoffeeScript, for truly reusable code.

    Yann is a member of the french Ruby community. He recently moved to London to join Yammer as Rails engineer.

    Dealing with Scale at Yammer: Caching and Services In this talk, I’ll describe Yammer architecture and how it has grown from a simple Rails application to a powerhouse serving over 6 million users this year. Our scaling strategy relies on 3 points: caching, sharding and specialised services. I'll give an overview of our choices on sharding and services then go deeper on the way we do data caching.

    Katrina ran away from the circus and found her true home in the land of computers and code. She enjoys optimizing and automating, taking busywork away from smart people and putting it into code where it belongs. She is the problem solver you want on your side. She is driven by an inexplicable urge to refactor, and has for the past 6 years volunteered as a nitpicker at the Cattle Drive, where she attempts to brainwash others to write clean code. She appreciates a good steak, and admits to enjoying a nice stick fight.

    Therapeutic Refactoring Enter deadline center stage, exit best practices, quietly, rear stage left. The results are rarely pretty. Refactoring can pry panic’s fingers away from your poor, overburdened adrenal glands and restore your sanity. Not that it went missing, of course. Never that! This talk will cover the two reasons why refactoring works as well as (or better than) whiskey, sky diving, and massages as therapy, explore a handful of effective strategies to ensure that the rubber meets the road, and contains gory before shots and slick after shots of ruby code that has served therapeutic purpose.

    Ryan’s a Ruby fanatic with a love of languages, programming and otherwise. He’s well travelled and has worked on projects of varying complexity for companies you’ve probably heard of. He’s also a little bit nuts when it comes to communication and has a burning passion for getting groups of people together to solve their problems. He also really hates describing himself in the third person and has only recently gotten over his aversion to tofu.

    Cultured localisation, or 'how not to offend 1 billion people'
    This talk isn’t really about localisation or internationalisation (add a ‘z’ if you prefer!) – it’s about culture and understanding. It’s about how we should all be approaching localisation challenges as people problems and to give good examples of how to get it right and where you can go so very wrong.

    Your framework and tool of choice is the easy part – understanding the people you’re wanting to each out to is oh-so-very hard and too often seen as only just a translation problem – a simple matter of swapping one string for another.

    I’ll talk about how people communicate across cultures, even when they are so different. Drawing on my experience as a teacher of english as a foreign language and my own travels and struggles to absorb another people’s language and culture, I hope I’ll change how you think about solving these problems in future.

    Hell, I’ll even make you laugh. I hope. The most important thing though, I’ll provoke a discussion, given the diverse multilingual background of the attendees here; it could be a very good one.
