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?

Hi World. I didn’t lost a bit of  grip on edge news, altrought now I am married!

In the first days of May we read about a new serach engine, called WolframAlpha.

The idea behind WolframAlpha are interesting, so we will take a close look to it.

Slashdot is following the engine very tightly (“Wolfram Alpha Launches Tonight, On Camera”, published  on May 16) ans so will do Gioorgi.com.

Col voto di martedì i cittadini della West Coast hanno respinto ad ampia maggioranza gli interventi fiscali (un’addizionale dell’1% sull’imposta di consumo, un aumento della tassa di circolazione e un incremento dello 0,25% dell’Irpef californiana) coi quali il governatore e il Parlamento dello Stato avevano deciso di colmare un deficit di bilancio di ben 21 miliardi di dollari. L'unica «proposition» approvata è quella che vieta ogni aumento retributivo per parlamentari e pubblici amministratori quando il bilancio è in passivo (ieri sono stati ridotti del 18% gli stipendi dei funzionari dello Stato con cariche elettive).
