For me, the best approach was take advantage of Java Concurrency API, but I've still had some questions, so at <a href='http://fisl.softwarelivre.org'>FISL</a> (International Forum of Free Software) me and my friend Mir0 from IBM, we had a chance to ask directly to Sun's executives (Ray Gans, Rich Sands from OpenJDK project) what they think about Java for Multicore. The result was post by Mir0 into YouTube. <a href='http://www.youtube.com/watch'v=WeFOs4BmY18'>http://www.youtube.com/watch'v=WeFOs4BmY18</a> <object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/WeFOs4BmY18&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/WeFOs4BmY18&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object> <b>Links:</b> <a href='http://weblogs.java.net/blog/ray_gans/'>Ray Gans Blog</a> <a href='http://blogs.sun.com/rsands/'>Rich Sands Blog</a> <a href='http://mirolima.wordpress.com/'>Mir0 Blog</a> <a href='http://www.javaworld.com/javaworld/jw-09-2007/jw-09-multicoreprocessing.html'>Multicore processing for client-side Java applications</a> <a href='http://dev2dev.bea.com/blog/hstahl/archive/2006/12/multicore_is_go.html'>Henrik Stahl's Blog: Multi-core may be good for Java!</a> <a href='http://www.theserverside.com/blogs/thread.tss'thread_id=43541'>Is Multi-core really that bad for Java</a> <a href='http://forum.java.sun.com/thread.jspa'threadID=5153516&messageID=9578995'>Concurrency - Java and Multicore</a> <a href='http://www.artima.com/forums/flat.jsp'forum=276&thread=170444'>Java Community News - The Impact of Multi-Core CPUs on Developers</a> Damico 2008-04-24 http://dcon.com.br/dbjmin http://dcon.com.br/dbjmin http://dcon.com.br/dbjmin#comments As promised, the improvements live-coded at <a href='http://fisl.softwarelivre.org'>FISL</a> were tested and distributed today as a new release 0.1.8.

(Could not connect to: / Cannot locate host: / java.net.UnknownHostException:). Just add -Djava.net.preferIPv4Stack=true to eclipse.ini and will work. :) Damico 2008-04-24 #comments Oi pessoal, nesta quinta-feira 13/setembro/2007 às 20h terei o prazer de ministrar a palestra sobre o tema "O papel dos padrões XML em SOA" em Ourinhos SP, na FIO (Faculdades Integradas de Ourinhos) no endereço 'Rodovia BR153 Km339 + 400m - Bairro Água do Cateto - Ourinhos/SP'. <img src='img/fotoo_01.jpg'><br> <br> <img src='http://dcon.com.br/jd.comment/img/unesp_bauru_semana_engenharia.png'><br> Damico 2008-04-24 http://dcon.com.br/XQueryREST/ http://dcon.com.br/XQueryREST/ http://dcon.com.br/XQueryREST/#comments Hi, two weeks ago I was trying to use XQuery with Saxon, but I've just found few examples on Internet, so I made an open-source example of it using a web interface.
