    Also, I forgot to explain what the word Tatami means!
    It's a mat used for judo and other martial arts:

      Also Julien Dubois @Ippon is one of the people behind http://jhipster.githu...­ It's an amazing AngularJS / Spring starter kit. And I'm thinking about moving tatami to that model.

    Here is my plan for the talk. Feel free to ask questions.
    1 - I will show you how we use Tatami at Ippon. The tool has drastically improved collaboration between consultants on different client sites. It is a way to share knowledge and to just have fun, in a secure environment. I will encourage you to test-drive Tatami in your workplace or for a community.

    2 - We will explore the technical stack and look at the code. The source code is hosted on github. Tatami uses BackboneJS, Spring MVC for REST, ElasticSearch and Cassandra (NoSQL). And many other cool things like Atmosphere for real-time browser info updates. I believe Tatami is a great playground to learn very marketable recent technologies. 3 - I will finish with a call for contributors. Ippon USA inherited Tatami recently. I am the product manager for it. I would love to get a few committers from the JUG. This could be a project that strengthens the JUG community too.
