When talking about Object Oriented Programming, there are several principles that are normally associated with the paradigm: polymorphism, inheritance, encapsulation, etc. I feel that people tend to forget the first, most important principle of OOP: object lifetime. One of the first things that struck me when I was learning OOP in the C++ programming language… Read More »
I had an interesting thought during an email conversation with a friend yesterday. One problem many people have when using XML for data is a misunderstanding of what the XML is. (If you don’t believe in the data in XML approach, feel free to ignore me.<grin/>) It’s easy to make the mistake of treating the… Read More »

At the time, I was moving from dabbling in SVG to beginning a contract which required the use of SVG. This book provides a good working overview of SVG. I have seen… Read More »
Earlier in this weblog, I listed some of my basic troubleshooting rules. I thought it was probably time to come back and spend a little more time on this topic. I plan to expand on the points I made earlier and add a few more thoughts along the way.
