Web Development in Heavy Traffic (O'Reilly)

Pier Fumagalli writes about tuning JVM for optimal performance on high-bandwidth web sites. "It happens from time to time: you spend a few years working on one peculiar aspect of a problem, you believe you become "experienced" in that problem, and, once your environment changes, you notice how you were looking at it with the eyes of a blind man."

Getting Started With Cocoon 2 (O'Reilly)

Steve Punte gives an overview of the Cocoon 2 XML publishing framework on O'Reilly. "Cocoon 2, part of the Apache XML Project, is a highly flexible web publishing framework built from reusable components. Although reusability is an oft-touted quality of software frameworks, Cocoon stands out because of the simplicity of the interface between the components. Cocoon 2 uses XML documents, via SAX, as its intercomponent API. As long as a component accepts and emits XML, it works."

Clustering with JBoss 3.0 (O'Reilly)

Bill Burke and Sacha Labourey introduce JBoss 3.0 on O'Reilly. "Whenever an organization thinks about building and deploying a J2EE application, they think scalability and reliability. How can my Web site stay up 24/7? Will my infrastructure be able to handle the traffic? How can I ensure that I don't lose any transactions or data? How do I manage large server farms?"

"To answer these questions, many Java architects look to their application server's clustering features. This article looks at the kinds of features needed to develop robust J2EE applications and how JBoss 3.0, an open source J2EE application server, can be the solution of choice."

Bringing KDE Closer to Joe User's Desktop (OSNews)

OSNews has posted a review of KDE 3. "It lacks two things: integration with the underlying system and UI polishing. Today, I will mostly talk about the polishing part, as a lot has been already said elsewhere about the seemingly unsolvable integration issue (because of the modularity and completely independant/remote software projects.) Update: And as I was just publishing this article, KDE 3.1-Alpha was released. I hope that some of my recommendations will make it to the final version of KDE 3.1."

Games

Humongous Python (O'Reilly)

Stephen Figgins writes about the use of Python by Humongous Entertainment. "While several game companies are now using Python in their games, Dawson says they are one of the few companies using Python as the base language of their game. "In most games, the game itself is written in C++ and they call out to the scripting language for a few triggers or AI events or something. With our games, and the Disney game Toontown, the executable is Python.exe. You boot up with a python script that starts the game, and it calls out the C++ modules to do the heavy lifting, like the graphics and sound. The game logic is written in Python, with the C++ off in the leaf nodes, instead of the reverse, which is much more common.""

Is your Java code secure -- or exposed? (IBM developerWorks)

IBM's developerWorks has an article about dealing with static security vulnerabilities in Java web applications. "Applications can be vulnerable to two kinds of security threats: static and dynamic. While dynamic threats are not fully under a developer's control, there are precautions you can take to counteract static threats while developing an application. This article outlines and explains 13 types of static exposures -- flaws in a system that leave it open to an attacker who wants to usurp privileges on that system. You'll learn how to deal with these exposures and discover the impact they can have if they are not addressed."

Fluent Perl (SAGE)

SAGE has published A Perl Tutorial that explains how to improve your Perl coding style. "Writing good Perl is not just about writing code that solves the task at hand correctly when run. If that were the only yardstick by which code were measured, winners of the Obfuscated Perl Contests would be lauded for their compact efficiency and emulated whenever possible. In this series of articles, I'll explore how you can write Perl fluently, so that your code is more readable, maintainable, and efficient."

A Test::MockObject Illustrated Example

O'Reilly's perl.com features an article that shows how to perform unit testing on object-orient code with Test::MockObject. "People like to find excuses to avoid writing tests for their code. One of the most common goes something like, "It's not feasible to test this, because it relies on external objects" - CGI code, code using the Apache request object, TCP/IP servers, and so on. The Test::MockObject module makes it much easier to isolate code that uses such objects."

Generator-based state machines (IBM developerWorks)

David Mertz writes about Python simple generators on IBM's developerWorks. "It takes a while to completely "get" Python 2.2's new generators. Even after writing an introduction to simple generators in an earlier "Charming Python" installment, I could not say that I fully understood the "gestalt" of generators. This article presents some additional patterns for the use of generators, and hopefully brings both myself and readers further into the mindset of "resumable functions.""

XSH, An XML Editing Shell

Kip Hampton introduces XML::XSH on O'Reilly. "A few months ago we briefly examined some of the command line utilities available to users of Perl and XML. This month we will continue in that vein by looking at the 300-pound gorilla of Perl/XML command line tools, Petr Pajas' intriguing XML::XSH. XML::XSH and the xsh executable provide a rich shell environment which makes performing common XML-related tasks as terse and straightforward as using a UNIX shells like bash or csh. Yes, that's right -- an XML editing shell. As we will see, it's not as crazy as it seems."

Keeping pace with James Clark

Uche Ogbuji writes about the accomplishments James Clark, a leading authority on markup languages. An interview is also included in the article. "James Clark is arguably the most accomplished developer in the world of markup languages. In his distinguished career of contributing to both SGML and XML, he has served on standards bodies, provided important practical perspectives on where markup meets traditional code, and most importantly, written many of the programs that have moved XML (and SGML before it) from the world of abstract speculation into hard practicality. In this article, Uche Ogbuji interviews James Clark, concentrating on a discussion of practical developments, current and future, in the world of XML."
