| 13 from IBM: TPTP, PS3 SPEs, NFS, IOC, XML, PHP, Perl, QEDWiki... |
Feb. 09, 2007
IBM has published the following new technical articles, tutorials, and downloads on its DeveloperWorks and AlphaWorks websites. They cover a range of interesting (though not necessarily embedded) technical topics, primarily related to Linux and open source system development. Some require free registration.
- ARM Performance Monitoring Made Easy with Eclipse -- This tutorial describes the newly released Eclipse Test & Performance Tools Platform (TPTP) project and explains how Application Response Measurement (ARM) V4.0 has been implemented with TPTP. Also learn the trade-offs and challenges involved in getting to this point and moving forward.
- Utility Computing 2.0 with Linux Server Farm -- You've heard of Web 2.0, right? Well, here's "utility computing 2.0," a combination of network booting, SSL, VNC, and other familiar concepts and technologies -- all on Linux -- that can yield dramatic returns on investment. See how the University of California set up a server farm environment to provide secure remote desktop application services for students.
- In depth SPE Programming of the Sony PS3 on linux -- Take even greater advantage of the synergistic processing elements (SPEs) of the Sony PLAYSTATION 3 (PS3) in this installment of Programming high-performance applications on the Cell BE processor. Part 1 showed how to install Linux on the PS3 and explored a short example program. Part 2 looks in depth at the Cell Broadband Engine processor's SPEs and how they work at the lowest level.
- Five Ways to Create Uniform Namespace with Autofs -- Trouble accessing data exported from multiple file servers? Try using open source implementations of autofs and Lightweight Directory Access Protocol (LDAP), with NFS Version 3, to access data under the same global mount point. In this article, study and compare five different methods to create a uniform namespace using autofs.
- Use Inversion of Control in method signatures -- This article describes how to use the pattern on method signatures to decrease the coupling between components and improve performance. IoC isn't just for components.
- Speaking UNIX: Command-line locution -- UNIX has a dialect all its own, and its vocabulary of commands is quite large. But you don't have to learn everything all at once. Here, discover more command-line combinations and expand your mastery of the UNIX language.
- XML::Simple for Perl developers -- XML has become pervasive in the computing world and is buried more and more deeply into modern applications and operating systems. It's imperative for the Perl programmer to develop a good understanding of how to use it. In a surprisingly large number of cases, you only need one tool to integrate XML into a Perl application, XML::Simple. This article tells you where to get it, how to use it, and where to go next.
- Advanced XML parsing techniques using Perl -- This article shows you how to convert an XML document using Perl into a tree of objects in memory. Most Perl programmers find this approach more natural, and it is indeed more convenient. It then introduces you to SAX and event-based parsing, an entirely different style of programming, one that turns out to be very rich, using the SAX pipeline.
- Memory-efficient XML parsing in PHP with XMLReader -- PHP 5 introduced XMLReader, a new class for reading Extensible Markup Language (XML). Unlike SimpleXML or the Document Object Model (DOM), XMLReader operates in streaming mode, which enables PHP pages to process XML documents in an efficient streaming mode. That is, it reads the document from start to finish. This makes it very fast, and very efficient.
- XForms as an RSS Reader/Editor -- RSS, Atom, and other syndication strategies involve making XML data available for download. This article explains how to create an XML reader and editor using XForms. XForms, which is designed to view and edit XML, is the perfect environment for an XML editor and reader.
- Essential Top 19 best practices for Java EE -- Over nearly the entire last decade, much has been written about Java EE best practices. There are now dozens of books and hundreds of articles that provide insight into how Java EE applications should be written. In fact, there are so many resources -- often with contradictory recommendations -- that merely navigating this maze has itself become an obstacle to adopting Java EE. This article provides some simple guidance for developers entering this world. It's a compiled best-of-the-best list of what are the most important and significant best practices for Java EE.
- Spring MVC: Using Web view technologies -- This tutorial, the final installment in a six-part series, shows you how to use JavaServer Pages (JSP), Velocity, Tiles, and PDF export using the Spring Framework. You'll experiment with the V in Model-View-Controller (MVC) -- the various Web views built into the Spring MVC.
- QEDWiki -- Take advantage of QEDWiki, an emerging mash-up maker technology that provides Web users and developers with a single Web application framework for hosting and developing Web 2.0 applications. Business users can quickly and easily create their own Web applications without depending on software engineers.
