Building a scalable API with Grails Tanausú cerdeña Greach 2013, 26/Jan/2013, Madrid, Spain http://greach.es/sessions-2013/tanausu-cerdena-building-a-scalable-api-with-grails Geosophic is a platform of online services for mobile games. It offers both user engagement features (such as leaderboards and achievements) and analytics. In this talk I would like to share with you our experience building this platform with Grails with the goal to support a big load. I'll focus on the system architecture, the problems we have found and how we are solving them. Specifically: -- API: Design and implementation, authentication, tracking requests. -- Availability: Monitoring and minimizing downtime while updating. -- Data storage: Connection to data stores, caching. I would like to finish with my conclussions about the question "Is Grails a good match for a large scale API?" and listen to what the audience think in this regard. Tanausú Cerdeña Software developer with a heavy background in systems administration. I've worked for small companies developing in Java and discovered Grails a couple of years ago and fall in love with it. Currently I'm CTO and co-founder at Geosophic, a company that offers online location services and analytics for mobile gaming studios, where I enjoy designing systems, building APIs and digging into every piece of data I get.

Groovy AST Demystified Andrés Almiray Greach 2013 - 25/Jan/2013, Madrid, Spain http://greach.es/sessions-2013/andres-almiray-groovy-ast-demystified Compilers are powerful tools, they pretty much translate your thoughts into machine code. Extensible compilers are even more powerful. It turns out that the Groovy compiler can be extended by means of AST transformations. Come learn why and how popular Groovy projects like Grails, Griffon and Spock, have reached out to AST transformations and AST manipulation to boost their success. In this talk we'll dive deep into compiler specifics, by all means bring your laptop if you'd like to hack along.

Building a Groovy DSL with user interaction Corinne Krych and Sébastien Blanc Greach 2013 - 26/Jan/2013, Madrid, Spain http://greach.es/sessions-2013/corinne-krych-and-sebastien-blanc-building-a-groovy-dsl-with-user-interaction Do you want to follow a step by step guide on how to build a DSL in Groovy? Using techniques like BaseScript, AST, bindings and command chaining, we will explain how to implement a DSL that produce an user interface and that manage User Interaction. Corinne Krych. With over XX years of experience in development (when you like it you don't count), Corinne is addicted to code and can't go very far from it. Freelance since 1999, she traveled from C++ to Java, J2EE, Spring, Struts, JSP, Web 2.0 and naturally made her path to Groovy. Being an Agile coach and practitioner, she thinks code is craft and collaboration is key to success. Chatting about the latest tech trends at coffee break: a female geek -- what do you expect -- she's always curious to discover (or rediscover) languages and frameworks. She is co-founder of RivieraGUG (Grails and Groovy User Group) and an active member of JS Sophia: because there is no better way to achieve continuous learning than sharing ideas. Sébastien Blanc is JEE engineer with 8 years of experience. After spending 7 years in the Netherlands as Software Engineer, he decided to back to the his roots in the South of France. He recently joined the AeroGear team with Red Hat to work on open source libraries for Mobile in the enterprise. Besides his "heavy" JEE profile (middleware, banking and insurance products) Sébastien spends a lot of time in Groovy and Grails. He is the author of several Grails plugins such as Spring Mobile, Jquery Mobile Scaffolding or Geolocation. He believes that Mobile Web Apps are the future and tries to evangelize this through different conferences (Gr8Conf, Devoxx, RivieraDev, Grails Exchange).

Testing Gaelyk applications Marcin Erdmann Greach 2013 - 25/Jan/2013, Madrid, Spain http://greach.es/sessions-2013/marcin-erdmann-testing-gaelyk-applications In this talk I would like to present different ways to test Gaelyk applications. I will start with showing how to unit test Gaelyk groovlets using gaelyk-spock library. The second part will focus on the latest facilitations of writing functional tests for Gaelyk applications using Geb framework. I will show how to modify the state of the application under test using Gaelyk Remote and explain which common test tasks can be performed using Gaelyk Functional Test Tools. The talk will be example driven and I will try to come up with examples that are as close to real life as possible. Marcin Erdmann Grails Developer at BSkyB I've become interested in Groovy while working in Berlin in spring 2010. I liked it so much that I decided to shift my career towards web development with Grails. I'm really happy to have made that decision back then as Groovy ecosystem is not only full of good projects but it's also full of friendly and outstanding developers. That's why I like going to conferences focused on Groovy and sometimes even become a speaker at them. I believe in Open Source Software and have a strong need to give back to the community whenever possible especially as I make a living using Grails which is an open source project. That's why I'm proud to be one of the core commiters of Geb. I've also managed to get few pull requests accepted into many Groovy ecosystem projects like Grails, Gaelyk and Codenarc to name a few. I've worked in four different countries (Poland, Germany, The Netherlands, United Kingdom) with different technologies and languages (from Java through Javascript, Python and Ruby to Groovy) and developed my skills over the years. I believe that software should not only work, but also has to be 'beautiful under the hood', maintainable, well-tested and the source code should be clean and consistent. And I can't imagine coding without doing TDD anymore...

http://greach.es/sessions-2013/alberto-vilches-y-roberto-martin-como-crear-una-plataforma-de-libros-electronicos Cómo crear una plataforma de libros electrónicos y no morir en el intento Alberto Vilches y Roberto Martín Greach 2013 - 25/Jan/2013, Madrid, Spain Llevamos más de un año construyendo una plataforma con el que miles de personas en España pueden comprar y descargarse libros. Controlamos desde el diseño y venta de los Ereaders, hasta los contratos con las editoriales y venta y descarga de libros. ¿Cómo lo hemos conseguido? En esta charla trataremos de explicar el desarrollo en Grails de la parte servidor que se encarga de almacenar y servir los libros a todos los dispositivos y aplicaciones, proporcionar los contenidos de las tiendas, y que soporta al día más de un millón de peticiones. Hablaremos sobre negocio, arquitectura de sistemas, MySql, ElasticSearch, optimización de base de datos y consultas y, como no, Grails! Alberto Vilches I started to develop in 1998 and I've been working with Java the last 10 years. But now I'm a Groovy and Grails fan, so I created Greach to spread the Groovy word in Spain. I worked for many clients and company as developer, project leader, instructor and consultant. Now I work for MundoReader creating the server side of his new ebook platform to defeat Amazon Kindle in Spain. I use to go to the GR8 or Grails Exchange events as attendee, and you can find me in the Madrid Groovy User Group every month. My twitter is @albertovilches and my Grails blog http://albertovilches.com. Roberto Martín Desarrollador de software, interesado en metodologías ágiles y Atlassian fan. Inicié mi carrera profesional en Salenda en el año 2009, donde comencé a trabajar con Groovy/Grails. Desde entonces me dedico al desarrollo de aplicaciones web principalmente en este lenguaje. En la actualidad formo parte del equipo de plataforma en Mundo Reader (@bqreaders). Practico el continuous-learning investigando y aprendiendo de mis mentores. Tengo la suerte de disfrutar en mi trabajo. Puedes encontrarme en Twitter @roberto_mf.

Aunque PHP es, con mucha diferencia, el lenguaje más popular para programar sitios web, no es el único. ¿Qué podemos aprender de Java, Python y Ruby? ¿Qué herramientas y buenas prácticas de esos lenguajes podemos tomar prestadas y adaptar? El software libre y compartir son las claves para abrir tu mente y aprovechar el trabajo de otras comunidades.

Algún día me tenía que pasar. Después de ver tanto backend Java en cursos de todos los colores y de coleccionar certificaciones Java, después de desarrollar para iOS y webOS, alguna vez me tenía que poner en serio con Android. De hecho, siempre me han preguntado que por qué no era esta mi plataforma de […] - por Diego Freniche
