Last week, I was in Stockholm, Sweden, for the JFokus conference. Mattias Karlsson had invited me to speak about how to benefit from Groovy, how / when / why developers, projects, companies are using and adopting Groovy in their everyday life. So I crafted a brand new presentation illustrating those usage patterns, how they are applied, also giving some examples of existing projects or companies benefiting from Groovy in that way.

Last week, I was in London for the JAX London 2013 conference. I gave a presentation on what makes the Groovy programming language… groovy! It’s essentially an introduction to Groovy, its language constructs, its ecosystem, etc. It’s not focusing particularly on new features or on metaprogramming, but tries to bring the audience to the boilerplate killer that is Groovy. I’ve posted the slides on SpeakerDeck and I embed them below: Read more...

I’ve had the pleasure of being invited at the Scala.IO conference to speak about the functional aspects of Groovy, as the conference was also open to other functional language. The Groovy programming language, since its inception, has always been pretty functional, in particular with the cornerstone that our Closures represent to serve as first-class citizen functions in the language. Inspired by other nice talks from Andrés, Paul, Arturo, I’ve created my own deck that I’ve posted on SpeakerDeck and that I embed below. Read more...

GR8Conf Europe 2013 was such a blast! With close to well over 160 attendees, the conference was a real success, and went flawlessly thanks to the great organization of Søren and his crew. Big congrats to his team! And for the 5th anniversary of the conference, the Groovy cakes were so delicious! It was a pleasure to be back in Copenhagen to meet all my friends from the Groovy community. Read more...

Last week, I had the pleasure to attend and keynote at the 5th edition of the Groovy / Grails eXchange conference, in London. I presented a talk around the new features of Groovy 2.0 and the upcoming 2.1 release, as well as a few words about what’s coming up next. You can watch the video online, as SkillsMatter, the organizer of the conference, have put all the presentations online in record time! Read more...

Last week, I was in Washington DC for the SpringOne2GX conference. I’ve had the pleasure of presenting twice: first time on an update on Groovy 2.0 (and a recap on key features of Groovy 1.8), and a second time with my friends and colleagues Paul King (Groovy core committer) and Andrew Eisenberg (Groovy/Grails Eclipse tooling lead) about Domain-Specific Languages in Groovy. Please see the slides published below:

During the Cloud Foundry Open Tour conference in Moscow, I presented a new presentation of Domain-Specific Languages in Groovy. I’ve already shared the link here and there (twitter, Google+, mailing-list), but not yet on my blog. So consder this fixed now. This new presentation is inspired from the beta DSL chapter from the second edition of Groovy in Action, where you’ll learn how to create a DSL for a little Mars robot. Read more...

Last week saw the first edition of Devoxx France. And what a success it was! The conference was sold out at 1200 persons. There was a great wealth of interesting topics and many passionate attendees to talk to. Overall, I come back home impressed that the first edition worked out so well, flawlessly, and was such a joy to attend. So a big thank you and congrats to all those involved in making Devoxx France such a great event! Read more...

Here are the slides of the Groovy 2.0 presentation I’ve given at the 33rd Degree conference in Krakow.

Warning: Sorry, this time, I’ll blog in French to share my slides of the presentation in French that I made yesterday at the Paris JUG about the PrettyTime library and the GPars concurrency / parallelism toolkit. Hier soir, j’ai eu le plaisir de retrouver les passionnés du Paris JUG pour parler sur le thème des “petites librairies” utiles que l’on peut utiliser sur nos projets. J’avais proposé de parler de PrettyTime, qui permet d’écrire des dates relatives du genre “il y a 3 minutes” ou “dans 4 jours”. Read more...
