XSLT Variable Arrays

I recently answered a question on a popular programmers forum about how to store and access an array of user-defined variables in a stylesheet and then loop though those variables.  I realized that many developers are not familar with the available techniques for doing this and decided to add an entry in my blog about this topic. User-defined variable arrays within stylesheets are not part of the XSLT specification.  The usual way to handle this problem in XSLT 1.0 stylesheets is to define a user-defined top-level element which belongs to a non-null namespace which is different from the XSLT namspace.  These user-defined

Google Page Translator

Today, I added a gadget to my blog so that readers can easily translate my posts into any one of thirty five languages using the Google Translate webpage language translation engine.  You will find it low on the left hand side of this webpage.  From the drop down list, just pick the language you want to convert the current post to and after a short delay a new webpage will appear with the post displayed in the selected language.  Note – you need to have scripts enabled in your browser for the Google gadget to display on this webpage. Adding this functionality was

More on PowerShell

Microsoft’s PowerShell is radically different than shells on UNIX or GNU Linux systems in that Powershell can deal in objects rather than just plain text. A concrete example may help you more quickly understand the difference.  Suppose you want to get and save information about all the files in a certain subdirectory.   We want to get not only the names of the files but as much metadata as possible relating to each file such as date of creation, date of modification, etc.  This information also needs to be stored in a single XML document.  To keep the size of this post manageable,

Grady Booch Podcasts

To anybody who has received formal software enginnering training, the name Grady Booch is instantly recognizable for his work and influence on software architecture, software engineering, and modeling. He was an early advocate of formal software engineering, object orientated design and what we know today as software patterns.  The Booch Method, which he detailed in his book Object Oriented Analysis and Design is an object modeling language and software development methodology that was widely used in object-oriented analysis.  Along with with Ivar Jacobson and James Rumbaugh, he co-developed version 1.0 of the Unified Modeling Language. Unless you are a member of the

PowerShell Grows Up

I am excited about the emminent release of Microsoft Windows Powershell Version 2 CTP3 (Community Technology Preview Version 3) which is due “real soon now.”   The first CTP for Powershell 2.0 was in November 2007 and there has been a lot of progress on the product since then.  See the permanant link at the side of my blog to access the Powershell developers blog. Why am I, a UNIX/Linux developer, excited by Powershell V2?  After all it does not run on any UNIX or GNU Linux platform and microsoft has no plans to port itMto these platforms.  The main reason is that Powershell
