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?

WinRun4j is a java launcher for windows. It is an alternative to javaw.exe and provides the following benefits:

• Uses an INI file for specifying classpath, main class, vm args, program args.

• Custom executable name that appears in task manager.

• Additional JVM args for more flexible memory use.

• Built-in icon replacer for custom icon.

• Pre-JVM splash screen with auto-hide.

• DDE implementation for file assocations.

• Windows NT Service wrapper.

• Windows EventLog API

• Console version

• JNI library for INI access, splash screen, logger, registry, shell.

• Support for 64-bit JVM.

• Supports embedding (inside the executable) the INI file. See Embedded Resources section below.

• Supports embedding a splash image.

• Supports embedding JAR files. These will be included in the classpath (without extraction). This is currently BETA quality.

• NEW: There is now an Eclipse Plugin for WinRun4J.

WinRun4J is licensed under the Common Public License (CPL).

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!!]

ack is a tool like grep, aimed at programmers with large trees of heterogeneous source code.

ack is written purely in Perl, and takes advantage of the power of Perl’s regular expressions.

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).

Working for a very big customer, I found a very nasty interaction between Sun HttpClient (JDK 1.4) and Http  Load Balancers.

In a complex network environment, sometimes you can experience low level TCP/IP comunication errors, because sometimes HttpClient get confused and hangs.

The bad behavior of Sun HttpClient is well known: some guys suggested me to use the Axis Web Client. Anyway you can solve the issue adding these three parameters to the JVM launch line

Sometimes Eclipse Ganymede will not run if it is unable to find a jdk 1.5 or greater.

Sometimes Eclipse Ganymede  hangs abruptly if you delete the jdk  it was using and if you have set only a JDK 1.4 on your path (Eclipse needs a jdk 1.5 or greater…).
