Data Push Apps with HTML5 SSE

Disclaimer: The book was given as part of the blogger review scheme from O'Reilly.

I have read the book today and frankly was disappointed. Main chapters talking about json, javascript and html, how to use apache and back and forth.
Was hoping to see fireworks and i read bubble gums. It's ok but is for beginners, nothing fancy nor complex. Using php for serving the pages and node.js as back-end.
Example are shown trough the stock market, live update from values and symbols. 

Nicest part, the notes for improvements. 
Didn't learn a lot, just basics. Probably the interest chapter are the last 2, authentication and fall back ways from SSE to normal polling with ajax. Nothing that I've didn't heard of.

I won't recommend it.

Programming Elastic MapReduce book

Address the trending topic of the cloud computing, showing how in particular to deploy your application on amazon cloud.
Well written, have it in your library as a guide or just to know more about the world of virtualization.

Not only that, but it is also explaining the MapReduce paradigm using the Amazon infrastructure.

Everybody knows Hadoop, right? Well, EMR is the Amazon PaaS to deploy your mapreduce app.

I recommend it for people who want to understand the modern application and the MapReduce real examples.
