Screen-scraping with XQuery (IBM developerWorks) Brian Goetz scrapes screens with XQuery on IBM developerWorks. "XQuery is a W3C standard for extracting information from XML documents, currently spanning 14 working drafts. While the majority of interest in XQuery is centered around querying large bases of semi-structured document data, XQuery can be surprisingly effective for some much more mundane uses as well. In this month's Java theory and practice, columnist Brian Goetz shows you how XQuery can be used effectively as an HTML screen-scraping engine."
Lisp ParenScript 0.1.0 announced Initial release 0.1.0 of ParenScript, a Lisp to JavaScript translator, is out.

Perl Symbol Table Manipulation (O'Reilly) Phil Crow works with symbol tables under Perl on O'Reilly. "My purpose here is not really to introduce you to this beautiful module. Instead, I'll explain how to build façades like this. To do so, I'll work through another, simpler CPAN module called Class::Colon. It turns colon-delimited files into classes and their lines into objects. Here's an example from a checkbook application. This program computes the balance of an account on a user-supplied date or the end of time if the user doesn't supply one."
Python Python 2.4.1, release candidate 2 Release candidate 2 of Python 2.4.1 is available. "Python 2.4.1 is a bug-fix release."

UML Unified Modeling Language version 2.0 (IBM developerWorks) Bran Selic discusses UML 2.0 on IBM developerWorks. "So-called "model-driven" development (MDD) methods, which are based on higher levels of abstraction and greater use of automation compared to traditional methods, have already demonstrated their potential for radical improvements in the quality of software and the productivity of development. Since the role of modeling languages is crucial to the success of MDD, a major revision of the industry-standard Unified Modeling Language (UML) was recently completed. While several important new modeling capabilities were added -- such as the ability to more accurately capture software architectures -- the dominant characteristic of this revision is the heightened precision of the language definition that enables greater levels of automation. This article explains how this was achieved and also describes other highlights of UML 2.0."
XML Tracking Packages with RSS (O'Reilly) Yakov Shafranovich uses RSS to track package shipments on O'Reilly. "With the increasing popularity of RSS and Atom, syndication is beginning to be used for many more innovative purposes than simply distributing website updates. In this article I want to show how to simplify such mundane tasks as tracking packages by converting tracking data into an RSS 2.0 feed."
Writing and Reading XML with XIST (O'Reilly) Uche Ogbuji works with XIST on O'Reilly. "XIST is a very interesting project I've been meaning to dig into for some time. If you've been following the news section at the end of each of these columns, you'll have noticed the steady work that Walter Dörwald, the project leader, has put into this toolkit. It started out as a framework for generating HTML and incidentally XML, but the XML facilities have steadily grown and matured, until it is now a sophisticated system for not only generating, but also processing, XML."
Profilers OProfile 0.8.2 has been released Version 0.8.2 of OProfile, a system-wide profiler for Linux, is available. Changes include support for PPC64 and MIPS performance counters, removal of unused features, and bug fixes.
Version Control An open source BitKeeper client BitMover has announced the availability of an open source BitKeeper client. The functionality is minimal - it can pull down the current copy of a public BitKeeper tree, and not much else. It will be useful, however, for those wanting to get at BitKeeper-hosted code without using proprietary software. It's available under the "no whining" license which, while not being OSI-certified, is likely to be free enough.
