If you give two programmers the same problem—it depends on the problem, but problems of a more mathematical nature, they can often end up writing the same code. Subject to just formatting issues and relabeling the variables and the function names, it's isomorphic—it's exactly the same algorithms. Are we creating these…
I guess to me the biggest change is that nowadays you can't possibly know everything that's going on in the computer. There are things that are absolutely out of your control because it's impossible to know everything about all the software. Back in the '7Os a computer had only 4,000 words of memory. It was possible…
Seibel: You mention four disciplines: music, graphics, mathematics, and text those are about as old as humanity. Clearly there are powerful ideas there that are independent of computers—the computer just provides a way to explore them that might be hard without the computer. Is there also a set of interesting…
Suppose someone describing something to me from postulates like. "Here's a computer and here are the op codes." I can visualize the structure of programs and how things are efficient or inefficient based on those op codes, by seeing the bottom and imagining the hierarchy. And i can see the same thing with programs. If…
And think about failure modes—I remember one of the great lessons I got about programming was when I showed up at the airport at Heathrow, and there was a power failure and none of the computers were working. But my plane was on time. Somehow they had gotten print-outs of all the flights. 1 don't know where—there must…
IN MOST contemporary educational situations where children come into contact with computers the computer is used to put children through their paces, to provide exercises of an appropriate level of difficulty, to provide feedback, and to dispense information. The computer programming the child. In the LOGO environment…
Omni: Does that limit the number of people who can contribute, or even understand what's being done? Feynman: Or else somebody will develop a way of thinking about the problems so that we can understand them more easily. Maybe they'll just teach it earlier and earlier. You know, it's not true that what is called…
In software design, when you find yourself feeling particularly proud of a neat little bit of design or code, stop and ask yourself how someone who didn't give birth to it will regard it. If it turns out to be overwrought or too slick for the need, you should probably kill your darling and replace it with an ordinary…
The first thing to face is that we shall not store all the technical and scientific papers in computer memory. We may tore the parts that can be summarized most succinctly--the quantitative parts and the reference citations--but not the whole. Books are among the most beautifully engineered, and human-engineered…
In computer programming our basic building block has an associated time grain of less than a microsecond, but our program may take hours of computation time. I do not know of any other technology covering a ratio of 10^10 or more: the computer, by virtue of its fantastic speed, seems to be the first to provide us with…
