I’ve been around software for 20 years now. Looking back, I have mixed feelings about the progress we’ve made. The end results have been amazing but the process of building software hasn’t fundamentally changed since the 80s. In fact, I see us make some of the same mistakes over and over again. One of the common anti-patterns is over-relying on tools and frameworks instead of inventing new programming models. Layers of abstraction are fundamental to software. Some layers are defined through programming models, e.g., machine language, assembly language, 3GLs, JSP. Others are defined through a combination of tools and frameworks, e.g., MFC and Visual Studio on top of C++. There is a limit to how high we can raise a level of abstraction through tools and frameworks alone. At some point, a new programming model is the best way forward. Here are some examples: CASE tools ... (more)

E-Commerce 2.0

With all the noise the Web 2.0 revolutionaries are making, it's easy to ignore another-this time velvet-revolution. E-commerce 2.0 is coming into maturity and getting ready to relieve its now 10+ year old predecessor. It's about time. What makes an e-commerce 2.0 site? Well, as Supreme Court Justice Stewart's famous saying (about pornography) goes: "I know it when I see it." This may not be a satisfactory answer but it's an honest one. It's too early to tell. E-commerce 2.0 sites look better, they are easier to use but, most importantly, they drive better economics. Let's look a... (more)

XML in Transit: Encoding Data

I just came back from the first face-to-face meeting of the W3C working group on XML Protocol (is it just me, or is the name somewhat odd-sounding?), and I'm wondering what topics to exclude from this column. Yes, that's right - exclude. Encoding data in XML is a difficult topic for many reasons. First, it's one of those technical subjects in which you need to look at lots of XML instance/schema/DTD snippets. Second, the devil is very much in the details and there are lots of them. Last but not least, there are as many ways to encode data in XML as there are data encoding needs. ... (more)

Web Services Directions

It's been a long time since the last XML in Transit column. Did you miss my musing on Web services? I doubt it. More likely, you were busy keeping up with all the new initiatives in the Web services space. Those of you with corporate responsibilities were probably wondering how to get some real ROI out of Web services. The more entrepreneurial of you were thinking how to make money in this new world. I too have been trying to organize my thoughts. This is going be the first in a series of articles that go beyond the basic SOAP/WSDL/UDDI Web services stack to cover the innovation ... (more)

How Can Metcalfe's Law Be Updated for Web 2.0?

"Metcalfe's Law is Wrong," contended Bob Briscoe, Andrew Odlyzko, and Benjamin Tilly recently in a much-discussed IEEE Spectrum article, in which they wrote: "Of all the popular ideas of the Internet boom, one of the most dangerously influential was Metcalfe's Law." Sim Simeonov disagrees. The industry is at it again – trying to figure out what to make of Metcalfe’s Law. This time it’s IEEE Spectrum with a controversially titled “Metcalfe’s Law is Wrong”. The main thrust of the argument is that the value of a network grows O(nlogn) as opposed t... (more)
