My soul has grown over the years, and some of my views have changed. As long as I am alive, I will continue to try to understand more because the work of the heart is never done. All through my life I have been tested. My will has been tested, my courage has been tested, my strength has been tested. Now my patience and endurance are being tested. Every step of the way I believe that God has been with me. And, more than ever, I know that he is with me now. I have learned to live my life one step, one breath, and one moment at a time, but it was a long road. I set out on a journey of love, seeking truth, peace and understanding. l am still learning.

"It's not the position of this program, or me, or [wife/program producer] Kathy [Bay], or anybody associated with this program to try to educate anybody about anything. You take from this program what you want; if you think I'm a wacko left-wing communist nutcase - fine! Run with it...jerk! If you think it's a fun program, go with that. If you get something - a link - go with that.

Intelligence has two parts, which we shall call the epistemological and the heuristic. The epistemological part is the representation of the world in such a form that the solution of problems follows from the facts expressed in the representation. The heuristic part is the mechanism that on the basis of the information solves the problem and decides what to do.
[...]
The right way to think about the general problems of metaphysics and epistemology is not to attempt to clear one's own mind of all knowledge and start with 'Cogito ergo sum' and build up from there. Instead, we propose to use all of our knowledge to construct a computer program that knows. The correctness of our philosophical system will be tested by numerous comparisons between the beliefs of the program and our own observations and knowledge.

Often, the program ends up amazing. You'll say, "This is beautifully architected." Well, where did that architecture come from?
In this case, architecture means the systematic way we deal with diverse requirements. Architecture allows us, when we go to do work we need to do on the program, to find where things go. It is a system that was worked into the program by all the little decisions we made — little decisions that were right, and little decisions that were wrong and corrected. In a sense we get the architecture without really trying. All the decisions in the context of the other decisions simply gel into an architecture.

 

Ward Cunningham

 

People could no longer learn hacking the way I did, by starting to work on a real operating system, making real improvements. In fact, in the 1980s I often came across newly graduated computer science majors who had never seen a real program in their lives. They had only seen toy exercises, school exercises, because every real program was a trade secret. They never had the experience of writing features for users to really use, and fixing the bugs that real users came across. The things you need to know to do real work.
