Yahoo has been a vociferous Apache Hadoop user and supporter for several years now, and uses it extensively within its Search technologies. Hadoop has been gaining popularity in the Cloud Computing space, with companies like the NYTimes converting 4TB and 11 million articles to PDFs in under 24 hours using Hadoop and EC2 in late 2007. Hadoop has been made available in Amazon's cloud and Yahoo has now released its own Hadoop version.

As processors become faster and multiprocessor systems become cheaper, the need to take advantage of multithreading in order to achieve full hardware resource utilization only increases the importance of being able to incorporate concurrency in a wide variety of application categories.
In this article we are evaluting a new approach to the concurrency. In the last five years computers are becoming even more parallel. Intel is pushing multi-core achiteture also on commodity personal computers. Neverless the computing power is ofter not well used: one again, hardware is a step head of our day-by-day software development. Remember when the 80286 came into light. The 286 was able to provide a multi-programming architecture but without memory management protection. We had to wait 386 hardware to see software working on preemptive multi-tasking, because software cannot cope with unprotected memory. In one word, it costs too much to develop a operating system without the new features the 80386 bring to us. What about concurrent programming? Can we look similarities in the concurrency field?

The Network Computer was a bad idea born in the middle of the ‘90, and ended up to be completly wrong. Anyway, the current software tecnologhy (like AJAX, Google Gears, the psedo-new-ms-windows os called midori) can be helpuful to sketch a new idea of operating system.
The network computer fails because it pretends to store all information (program, user data) on the server. Worst, it pretends a fee for application usage. But users preferred a buy-one model, because they didn’t like the renting model
In the NC world the Software company will also hold all you private documents, a very security concerns.
And the software company must guarantee also nobody will look your important market strategy stored on a corel draw excel. This things costs too much.
Even Apple is trying to remove DRM from Apple Store, selling some titles without it. The reason is simple: apple needs to upgrade its copy protection scheme, for avoiding some hacker will be able to crak it. But this costs too much!
Let’s see what we can think now, after 10 years, a bunch of iPhone/EEPC out of there and Open Source full of life…
