Von Neuman architecture sucks. From our educated and elevated point of view I think we can all agree on that. At least if we transcribe to "programming in machine language sucks". Perhaps one day we may elevate to agreement on "OO architecture sucks". OO is a successful technology measured by what has been accomplished with it. The von Neuman architecture is even more successful. The one and only architecture behind all general purpose computers. But no sane programmer would touch machine code directly. I have always thought that OO was wrong, in some sense at least. But I have to touch it. There is no higher and better level. There are alternatives but on the same level. So they suck in their own ways. I remember when I started forming my mental pictures of what programming in the large was all about. How to think about it. How to structure it in my mind. I read Object-Oriented Modeling and Design by Rumbaugh et.al. Even if the authors didn't succeed in explaining it fully, I got the vivid impression, that they wanted me to believe, that a computer model should be structured along three dimensions: data, functionality and events. A space with a recording axis, data, an activity axis, functions, and a time axis, events. Though a somewhat fuzzy picture, I "saw" these three dimensions as orthogonal and of equal importance in structuring and building the complex structures called programs. I find OO to intermingle the data-function-plane but leaving timing in the cold. A skewed space. I'm looking forward to the tools and technology, that will support my clean and "right" design model in a non-skewed concrete "code" space. Well, if they ever arrive, I might then have an even better mental model and find my self stuck with the new and better but sucking tools.
