MongoDB (is) For Rubyists

here's a link to a related talk given by Daniel Lucraft during the Ruby Manor 2009 on how #SongKick denormalised their rails application to make it more responsive using MongoDB. Interesting stuff.

Nice presentation!<p>Sorry that this is little off topic, but: MongoDB is released under the AGPL. As a MongoDB user, I have been fine with this because I always use mongodb as-is as a service, and will probably never want to modify it. Question though: why is it a big deal that MySQL be available with commercial licenses as long as it is used as a service, and there are non-GPL client libraries available? I asked this question before, but did not receive very many replies. The bruhaha over the Oracle Sun acquisition made me think more about this.

Looks like a good intro presentation to MongoDB, but I must say the slides themselves are absolutely beautiful and well done.
