“Word and Excel and PowerPoint and other Microsoft programs have intimate — one might say promiscuous — knowledge of each others' internals. In Unix, one tries to design programs to operate not specifically with each other, but with programs as yet unthought of.”

“My specific purpose for the first wiki was to create an environment where we might link together each other's experience to discover the pattern language of programming.”

Ward Cunningham (1949) American computer programmer who developed the first wiki

A Conversation with Ward Cunningham (2003), Exploring with Wiki
Context: My specific purpose for the first wiki was to create an environment where we might link together each other's experience to discover the pattern language of programming. I had previously worked with a HyperCard stack that was set up to achieve the same kind of goal. I knew people liked to read and author in that HyperCard stack, but it was single user.

“This is the Unix philosophy: Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface.”

“All the time we find ourselves in situations where people know things about the program, but they can't apply that knowledge to the program. Why? Because the knowledge runs counter to some organizational decision that was made before they had that knowledge. In other words, the program becomes resistant to that collection of knowledge.”

“In the good old days physicists repeated each other's experiments, just to be sure. Today they stick to FORTRAN, so that they can share each other's programs, bugs included.”

“Even perfect program verification can only establish that a program meets its specification. [… ] Much of the essence of building a program is in fact the debugging of the specification.”

“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 fished out listings of their operating system.”

“Overemphasis of efficiency leads to an unfortunate circularity in design: for reasons of efficiency early programming languages reflected the characteristics of the early computers, and each generation of computers reflects the needs of the programming languages of the preceding generation.”

Kenneth E. Iverson (1920–2004) Canadian computer scientist
