Last week I started hopping across conferences in Europe where I gave a couple of talks about Messaging with RabbitMQ. The first one was in Berlin for the Berlin Buzzwords conference. It was the second edition of this conference which this year focused on topics like “Big Data” –Hadoop, Riak and the likes– and Streaming Data where technologies that enable messaging like RabbitMQ come into place.After two days of conference I packed my bags and took the plane to London were I attended the Erlang Factory. Boy, I still can't believe how amazing that conference was. Seeing how many companies are leveraging Erlang to implement their applications effectively was really interesting. I found quite interesting that the conference had a complete track about testing Erlang applications. There were delegates from Heroku, AOL, Mochimedia and Basho to name a few. The use case of AOL was quite impressive. The speaker presented a “ Framework for Real-time Computational Advertising” written in Erlang. Somebody in the audience asked him how many developers implemented the framework. The answer was “It was myself, alone”. If that doesn't speak about Erlang power as a language, then what does.Even better was that the Keynote for the second day of the conference was about a new testing framework called PropEr. I think that speaks well about how quality oriented the language is.What I think was the highlight of the conference was that the guys from “ Erlang the Movie” where at the conference. Mike Williams –one of the Erlang creators– held the keynote the first day where at some point they re-enacted the movie famous lines of “-Helo Joe. –Hello Mike”.Besides from the conferences I had the chance to go to the “Pub-Sub” meetup in London, where I could meet with RabbitMQ's core developers among others. There I delivered to them a Chinese Rabbit that has been traveling for a while with me. It departed from Shanghai last March, went to Paris, Zurich, Berlin and finally made it to the RabbitMQ mecca –don't worry, it's not a real Rabbit–.All in all great fun at both conferences and I really hope I can be there next year.Finally the slides from my talk can be found here.
