Research in the sun – developer evening in Barcelona

Last week the Yahoo! Developer Network went to Barcelona, Spain to host our first local developer evening. Around 40 developers showed up to hear about what Yahoo! offers for developers and to get expert answers to their questions.


Yahoo!'s presence in Barcelona is twofold: there's a sales and marketing office that's a sight to behold. The research office is a tad more cramped -- it shares space with university students and staff, but has an amazing aura of creativity.

Yahoo! Research Barcelona has produced some very cool prototypes -- they can be found in the Yahoo! Sandbox. We spent a great day chatting with the team about their current projects and how YDN could help take some of these solutions to the next level.

In the evening, developers from the community arrived and listened raptly to the presentation (which surprised me considering the gorgeous weather and other distractions). You can download the slides as a PDF (11mb) from S3 or watch them on Slideshare:

For detailed notes of the talk with code examples, please refer to this blog post.

I created two demos exclusively for this event. The first is a website about Barcelona. None of the content is maintained on the website - instead it is pulled from Wikipedia, Upcoming, Flickr, and Yahoo! Weather, with a few lines of PHP and quite a bit of YQL magic.

The other demo I showed uses YQL to do four different web searches in a single HTTP request, thus the page rendering does not slow down. This can be done both in PHP or in plain JavaScript and HTML.

We had a wonderful time in Barcelona. The movies about the city don't do it justice - even when they add Scarlett Johansson and Penélope Cruz. If you get a chance, come and see Barcelona - maybe when we're back for another event. ( Until then, you can check out our photos as proof.).
