A Quote by David Gelernter
For years, computer scientists were treating operating systems design as sort of an open-reserch issue, when the field's direction had been decided by commercial operations. Computer science has become completely cut off from reality.

My hacking involved pretty much exploring computer systems and obtaining access to the source code of telecommunication systems and computer operating systems, because my goal was to learn all I can about security vulnerabilities within these systems.
Part of what made the Macintosh great was that the people working on it were musicians, poets, and artists, and zoologists, and historians. They also happened to be the best computer scientists in the world. But if it hadn't been computer science, these people would have been doing amazing things in other fields.
Imagine you are writing an email. You are in front of the computer. You are operating the computer, clicking a mouse and typing on a keyboard, but the message will be sent to a human over the internet. So you are working before the computer, but with a human behind the computer.
Every disruptive innovation is powered by a simplifying technology, and then the technology has to get embedded in a different kind of a business model. The first two decades of digital computing were characterized by the huge mainframe computers that filled a whole room, and they had to be operated by PhD Computer Scientists. It took the engineers at IBM about four years to design these mainframe computers because there were no rules. It was an intuitive art and just by trial and error and experimentation they would evolve to a computer that worked.
I was never as focused in math, science, computer science, etcetera, as the people who were best at it. I wanted to create amazing screensavers that did beautiful visualizations of music. It's like, "Oh, I have to learn computer science to do that."
What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline. My answer to these questions is simple -it is the art of programming a computer. It is the art of designing efficient and elegant methods of getting a computer to solve problems, theoretical or practical, small or large, simple or complex. It is the art of translating this design into an effective and accurate computer program.
I majored in Computer Science at U.C. Berkeley and worked as a software developer for a couple of years. Then I taught high school computer science for over a decade and a half in Oakland, California.
Computer science is not as old as physics; it lags by a couple of hundred years. However, this does not mean that there is significantly less on the computer scientist's plate than on the physicist's: younger it may be, but it has had a far more intense upbringing!
The first thing I think, I was building computers, I started to build a computer when I was 17 or 18 at home, an IBM compatible computer, and then I started to sell computers, and when I sold a computer to a company called Ligo I think, and they were selling systems which became blockbuster.
I learned to work on a computer years before I was placed under house arrest. Fortunately I had two laptops when I was under house arrest - one an Apple and one a different operating system. I was very proud of that because I know how to use both systems.
My undergraduate work was in computer science and economics. It just happened to be at that time when 34 percent of computer-science majors were women. We didn't realize it was at the peak at the time.
My biggest challenges when I first started out were not having a computer or camera or Wi-Fi! The computer and the camera had to be borrowed, and there were times that I used the computer at the library, and I literally sat outside people's houses to steal their Internet connections.
The best way to prepare [to be a programmer] is to write programs, and to study great programs that other people have written. In my case, I went to the garbage cans at the Computer Science Center and I fished out listings of their operating systems.
The traditional notion of an architect having a vision of a building and then drawing it either on paper or on a computer and then constructing it isn't really how architecture works and in reality the computer has a lot of influence on design.
I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun.
Language is too complex for a computer to understand. It's not going to be able to make sense of what people are saying en masse. We need a new type of discipline that puts together computer scientists and social scientists, who can add context to the situation.
