Debugging quotes:

There has never been an unexpectedly short debugging period in the history of computers. -- Steven Levy
Building technical systems involves a lot of hard work and specialized knowledge: languages and protocols, coding and debugging, testing and refactoring. -- Jesse James Garrett
Science requires a society because even people who are trying to be good thinkers love their own thoughts and theories - much of the debugging has to be done by others. -- Alan Kay
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
The most frequent complaint is that it's hard. True. it's a hard game to win Also, many people ask me how to use the secret debugging commands, apparently under the impression that I'll tell them. -- Graham Nelson
--
The wages of sin is debugging. -- Ron Jeffries
When debugging, novices insert corrective code; experts remove defective code. -- Richard E. Pattis
System debugging has always been a graveyard-shift occupation, like astronomy. -- Fred Brooks
System debugging, like astronomy, has always been done chiefly at night. -- Fred Brooks
Programming allows you to think about thinking, and while debugging you learn learning. -- Nicholas Negroponte
The most effective debugging tool is still careful thought, coupled with judiciously placed print statements. -- Brian Kernighan
Treating your users as co-developers is your least-hassle route to rapid code improvement and effective debugging. -- Eric S. Raymond
The three most important aspects of debugging and real estate are the same: Location, Location, and Location. -- Richard E. Pattis
If debugging is the process of removing software bugs, then programming must be the process of putting them in. -- Edsger Dijkstra
I do as much debugging as possible on the Mac, but I occasionally must debug problems in the PC world, which is significantly slower. -- Robert Patterson
One of the headaches of high-tech test programmes is having to debug the test arrangements before you can start debugging the things you're trying to test. -- Henry Spencer
If you want more effective programmers, you will discover that they should not waste their time debugging, they should not introduce the bugs to start with. -- Edsger Dijkstra
The hardest part of the software task is arriving at a complete and consistent specification, and much of the essence of building a program is in fact the debugging of the specification. -- Fred Brooks
Early Apple machines -- don't know how to answer what it was like since there were so few tools. Just had to keep debugging by isolating a problem, looking at memory in the limited debugging (weaker than the DOS DEBUG and no symbols) patch and retry and then re-program, download and try again. And again... -- Bob Frankston
As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that a large part of my life from then on was going to be spent in finding mistakes in my own programs. -- Maurice Wilkes
Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%. -- Donald Knuth
