In the first installment of this post, I discussed the move that all of the major computer hardware vendors have made toward multi-core CPUs, and the resulting Multi-core Dilemma . I then summarized their strategies in two categories: homogenous and heterogenous. In Part 2, I’ll talk about pros and cons of each approach and some things to think about as you plan your parallel strategy

Avik Sengupta from Lab49 wrote an interesting Guest View in the latest SDTimes about recent additions to Java to improve support for programming to multi-core hardware. When I started talking about the Multi-core Dilemma a few years ago the conventional wisdom in the Java community still held that we wouldn’t have to do anything different – that Java would take care of it for us. I even touched off a nice little flame war with a posting on The Server Side… As Avik points out, Java does provide a powerful threading model that helps with multi-core, “ but in practice it may not be so easy. “ With the addition of the concurrency package and the new fork/join, the tools for parallelism in Java are greatly improved

History For almost 20 years, Rogue Wave Software has been one of the world’s leading providers of C++ libraries and components. From an early time in our evolution, we have provided the most widely portable C++ standard library available – the “Rogue Wave C++ Standard Library”. Rogue Wave SourcePro C++ (and its predecessor .h++ products) have supported building with the Rogue Wave C++ Standard Library and the “native” standard libraries (those that ship with each compiler) for years.

well as having a widely-read weblog he speaks frequently at industry events on technology trends and futures. At various times he has programmed mainframes, Windows and on the Web. Phipps was previously involved in OSI standards in the 80s, in the earliest commercial collaborative conferencing software in the early 90s, in introducing Java and XML to IBM and most recently with Sun’s blogging site, blogs.sun.com.

Just had a problem in resolving a DTD, stored at a remote URI, while loading an XML file into a XmlDocument. Usually a XmlUrlResolver is used to resolve remote XSD or DTD defined in an XML document, however the XmlUrlResolver doesn't perform Proxy authentication meaning that as soon as you try to load the document a WebException is raised saying “The remote server returned an error: (407) Proxy Authentication Required.”.
