What makes a platform?

Friday, February 23rd, 2007

Some time ago I was contemplating the concept of a platform. It is a term that is bandied around quite a bit, but I’m not sure if a formal definition exists (other than something flat on which you can build or place something).

Why I like ABAP

Wednesday, February 21st, 2007

This month marks two anniversaries for me. One is the engagement to my wife 6 years ago. The other is that I have been working for 10 years. I started out in ABAP and I’ve been doing ABAP ever since (with long excursions into Java along the way). I have come to greatly respect ABAP, with which I have chiefly been earning my bread and butter.

One of the things I got hung up on was how I could redirect to a particular page depending on the logic of the currently executing page (by doing a redirect on the server). An example would be if you access a particular page for which you need to be logged in. At this point, you would want to redirect the user to a logon page. I searched all over and found people asking the same question, even someone asking how to redirect in PHP the way one does in Struts, which I realize now is not a very sensible question, as Struts is a framework, and PHP is a language.
