Most of us are familiar (or must be familiar) with the law of Demeter (LoD) as documented here. Basically, the LoD stipulates the principle of least knowledge about the internal structure of your dependencies. Or as in the case of this toilet sign, “no looking at what is happening inside”. Let us say we have [...]

  Launching the Value Object Wizard I have launched a project called Value Object Wizard in sourceforge. Please take a quick look and send me your comments. The details are in the home page.  

A few years ago, one of my numerous job sojourns took me to an interesting project at a telecom company.  I was a developer then – as I would like to think of myself today as well – and had to maintain code that connected to numerous databases and published various services. In one of [...]

So I had yet another meeting with an enterprise architect today. We were selling a solution to their company which is one of the top few companies in the world in their professed field of expertise. Let us call this guy John to give him an identity despite the fact that, to me, he looked [...]

I remember perusing through an article on web services some time ago where the author  quips about the similarity between web services and teen sexuality. He said that in both cases, they talk more about it rather than do it and even if they do it they do it pretty bad. A similar comparison can [...]

But browsers, unlike blonds, learn from experience and keep these learnings for sometime. Which means that if [...]

This article delves more into the performance analysis exercise that I alluded to in a previous article. We begin our analysis with the web layer which serves as the entry and egress to our core application. Does your web layer buckle under load as the spider’s web here seems to have ?  Tweaking the web [...]

Application performance testing is just about the last thing that we may have to do before we could certify an application as production ready. Or it may be just about the last thing we do before we decide to discard the app in the dumpster. This may be a loud roar or a death knell [...]
