MapReduce Design patterns

Last and this week I have been preparing an introduction about the Map/Reduce algorithm I have found a lot of new excellent references (see my previous post) and I have read some books that I did not know. As a result I have made a compilation (it is just a summary that I will continue updating) that can serve as roadmap about what MapReduce is and what you can do with this programming model. As soon as I review my presentation and the examples I will upload them,
