After working with unix for years, we noticed it is difficult to get a very uniform approach to unix management.

One day, we have the need to create a fast cluster of linux machine, specialized and easy to segragate in different networks (for better security). We need web servers, integration servers (running java hudson), huge developer machines (running for instance eclispe) and so on.
It was not easy to find a good environment. This research lead us also to consider a very huge set of different and complex management software. In this series of article, we will show what we discovered.
Or final goal is to have a way to define a set of linux virutal machines, connect them and manage all using open source software. We also want tools easy to understand. We do not want super-optimized stuff, we have the “just it works well” approach.
We thinked about these types of virtual machine: super light LAMP servers, medim sized java tomcat servers (or udson servers), big database machines and super big development machines.

After reading an interesting article on Erlang and Java interoperability, I have decided to dedicate my spare time to Erlang.
O’Reilly has just published a wonderful book on Erlang, so I decided to dive into it.

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.
[UPDATED! Google Squared is out of there!!]
