UNIX is simple. But It just needs a genius
to understand its simplicity.
--Dennis Ritchie
Before software can be reusable, it first
has to be usable!!
--Ralph Johnson
Good judgment comes from experience,
and experience comes from bad judgment.
--Fred Brooks
Theory is when you know something, but
it doesn't work. Practice is when something works, but you don't know why
it works. Programmers combine theory and practice: Nothing works and they
don't know why.
It's hard enough to find
an error in your code when you're looking for it; it's
even harder
when you've assumed your code is error-free!!! (so true)
-Steve McConnell Code Complete
If builders built buildings the way programmers
wrote programs, then the first woodpecker that came along would destroy
civilisation.
-Gerald Weinberg
The Six Phases of a Project:
Enthusiasm
Disillusionment
Panic
Search for the Guilty
Punishment of the Innocent
Praise for non-participants
Good code is its own best
documentation. As you're about to add a comment, ask yourself,
'How
can I improve the code so that this comment isn't needed?
' Improve
the code and then document it to make it even clearer.
--Steve McConnell Code Complete
The trouble with the world is that the
stupid are cocksure and the intelligent are full of doubt.
--Bertrand Russell
No matter how slick (efficient) the demo
is in rehearsal, when you do it in front of a live audience the probability
of a flawless presentation is inversely proportional to the number of people
watching, raised to the power of the amount of money involved.
One of the main causes of the fall of the
Roman Empire was that, lacking zero, they had no way to indicate successful
termination of their C programs.
--Robert Firth
Fifty years of programming language research
and we end up with C++?
--Richard A. O'Keefe
C programmers never die. They are just
cast into void.
If debugging is the process of removing
bugs, then programming must be the process of putting them in.
--Edsger Dijkstra
You can either have software quality or
you can have pointer arithmetic, but you cannot have both at the same time.
--(Bertrand Meyer)
(Thoughtful...)
There are two ways to write error-free
programs; only the third works.
--Alan J. Perlis
Measuring programming progress by lines
of code is like measuring aircraft building progress by weight.
--Bill Gates
The first 90% of the code accounts for
the first 90% of the development time. The remaining 10% of the code accounts
for the other 90% of the development time.
--Tom Cargill
Programmers are in a race with the Universe
to create bigger and better idiot-proof programs, while the Universe is
trying to create bigger and better idiots. So far the Universe is winning.
--Anon
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 discovers debugging, 1949
I did say something along the lines of
"C makes it easy to shoot yourself in the foot; C++ makes it harder,
but when you do, it blows your whole leg off."
--Bjarne Stroustrup
It has been said that the great scientific
disciplines are examples of giants standing on the shoulders of other giants.
It has also been said that the software industry is an example of midgets
standing on the toes of other midgets.
--Alan Cooper About Face
Computers are useless. They can only give
you answers.
--Pablo Picasso
If the code and the comments disagree,
then both are probably wrong.
--attributed to Norm Schryer
Even if you're on the right track, you'll
get run over if you just sit there.
--Will Rogers
Einstein argued that there must be simplified
explanations of nature, because God is not capricious or arbitrary. No
such faith comforts the software engineer
.
--Fred Brooks, Jr.
As we said in the preface to the first
edition, C "wears well as one's experience with it grows." With
a decade more experience, we still feel that way.
--Brian Kernighan and Dennis Ritchie
Simplicity is prerequisite for reliability
--Edsger W.Dijkstra
I've finally learned what "upward
compatible" means. It means we get to keep all our old mistakes.
--Dennie van Tassel
Rules of Optimization:
Rule 1: Don't do it.
Rule 2 (for experts only): Don't do it
yet.
--M.A. Jackson
Most software today is very much like an
Egyptian pyramid with millions of bricks piled on top of each other, with
no structural integrity, but just done by brute force and thousands of
slaves.
--Alan Kay
Every program has (at least) two purposes:
the one for which it was written, and another for which it wasn't.
--Alan J. Perlis
Technology is dominated by two
types of people: Those who understand what they do not manage. Those who
manage what they do not understand.
--Putt's Law
Copy and paste is a design error
--David Parnas
Any code of your own that
you haven't looked at for six or more months might as well have been written
by someone else.
--Eagleson's law
The primary duty of an exception handler
is to get the error out of the lap of the programmer and into the surprised
face of the user. Provided you keep this cardinal rule in mind, you can't
go far wrong.
