Economics
“Anyone who believes exponential growth can go on forever in a finite world is either a madman or an economist”
– Kenneth Boulding
“You don’t know who’s swimming naked until the tide goes out.”

Computer Science
“Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.”
– Brian Kernighan
“Greenspun’s Tenth Rule of Programming: any sufficiently complicated C or Fortran program contains an ad hoc informally-specified bug-ridden slow implementation of half of Common Lisp.”
“…Including Common Lisp.”
- Robert Morris as an addendum to the above
“When I was thinking about Object-Oriented Programming, I wasn’t thinking about C++.”
– Alan Kay
“The x86 isn’t all that complex—it just doesn’t make a lot of sense.”
– Mike Johnson, Leader of 80×86 Design at AMD, Microprocessor Report (1994)
“The complexity of the x86 is not an impassable barrier….The biggest weakness in the x86 instruction set is the lack of registers coupled with an extremely painful addressing scheme.”
– Mike Johnson, Leader of 80×86 Design at AMD, Microprocessor Report (1994)
“I program my home computer, beam myself into the future.”
– Kraftwerk
As Brian W. Kernighan and Rob Pike put it in their truly excellent book “The Practice of Programming”, the chapter on debugging…
As personal choice, we tend not to use debuggers beyond getting a stack trace or the value of a variable or two. One reason is that it is easy to get lost in details of complicated data structures and control flow; we find stepping through a program less productive than thinking harder and adding output statements and self-checking code at critical places. Clicking over statements takes longer than scanning the output of judiciously-placed displays. It takes less time to decide where to put print statements than to single-step to the critical section of code, even assuming we know where that is. More important, debugging statements stay with the program; debugging sessions are transient.

This best described me at one point: KNOW YOUR UNIX SYSTEM ADMINISTRATOR– A FIELD GUIDE The Technical Thug: Usually a systems programmer who has been forced into system administration; writes scripts in a polyglot of the Bourne shell, sed, C, awk, Perl, and APL.
“HTML sucks.”
– Steve Dekorte, October 6, 1998, San Francisco
“Most things *ML, (ML, UML,XML), Suck. HTML sucks the least.”
– Steve Dekorte, October 6, 1998, San Francisco
“Never underestimate the crappiness of a free C compiler.”
– Dru Nelson, July 24, 2001, San Mateo – after watching programs that worked, not work with -O2 turned on
“OS’s should do lots of things…”
– Dru Nelson, November 11, 2001, Palo Alto (as a request by Steve to put this up)
Politics
“The cost of freedom is eternal vigilance” – Thomas Jefferson
Humor
“no job is as good as… no job.”
–Blake Commagere – in jest (natural state)
“Prediction is difficult, especially of the future.”
– Niels Bohr
“Everywhere is walking distance if you have the time.”
– Steven Wright
Wisdom of Crowds
“All truth passes through three stages: First, it is ridiculed; Second, it is violently opposed; and Third, it is accepted as self evident.”
“It is with trifles and when he is off guard that a man best reveals his character.”
“People of Wealth and the so called upper class suffer the most from boredom.”
“The discovery of truth is prevented more effectively not by the false appearance of things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice.”
– Arthur Schopenhauer – (1788-1860) German philosopher
“It is not the critic who counts, not the man who points out how the strong man stumbled, or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena; whose face is marred by the dust and sweat and blood; who strives valiantly; who errs and comes short again and again; who knows the great enthusiasms, the great devotions and spends himself in a worthy course; who at the best, knows in the end the triumph of high achievement, and who, at worst, if he fails, at least fails while daring greatly; so that his place shall never be with those cold and timid souls who know neither victory or defeat.”
–Theodore Roosevelt
