A good programmer is someone who looks both ways before crossing a one-way street. — Doug Linder, systems administrator
A most important, but also most elusive, aspect of any tool is its
influence on the habits of those who train themselves in its use. If the
tool is a programming language this influence is, whether we like it or
not, an influence on our thinking habits. — Edsger Dijkstra,
computer scientist
Being abstract is something profoundly different from being vague… The
purpose of abstraction is not to be vague, but to create a new semantic
level in which one can be absolutely precise. — Edsger Dijkstra
Besides a mathematical inclination, an exceptionally good mastery of
one's native tongue is the most vital asset of a competent programmer.
— Edsger Dijkstra
C makes it easy to shoot yourself in the foot; C++ makes it harder, but
when you do, it blows away your whole leg. — Bjarne Stroustrup,
developer of the C++ programming language
Commentary: most debugging problems are fixed easily; identifying the location of the problem is hard. — unknown
Considering the current sad state of our computer programs, software
development is clearly still a black art, and cannot yet be called an
engineering discipline. — Bill Clinton, former President of the
United States
For a long time it puzzled me how something so expensive, so leading
edge, could be so useless, and then it occurred to me that a computer is
a stupid machine with the ability to do incredibly smart things, while
computer programmers are smart people with the ability to do incredibly
stupid things. They are, in short, a perfect match. — Bill Bryson,
author, from Notes from a Big Country
Given enough eyeballs, all bugs are shallow (e.g., given a large enough
beta-tester and co-developer base, almost every problem will be
characterized quickly and the fix obvious to someone). — Eric S.
Raymond, programmer and advocate of open source software, from The Cathedral and the Bazaar
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, software engineer and author, from Code Complete
Hey! It compiles! Ship it! — unknown
Inside every well-written large program is a well-written small program. — Charles Antony Richard Hoare, computer scientist
It should be noted that no ethically-trained software engineer would
ever consent to write a DestroyBaghdad procedure. Basic professional
ethics would instead require him to write a DestroyCity procedure, to
which Baghdad could be given as a parameter. — Nathaniel S.
Borenstein, computer scientist
Managing programmers is like herding cats. — unknown
Measuring programming progress by lines of code is like measuring
aircraft building progress by weight. — Bill Gates, co-founder of
Microsoft Corporation
More good code has been written in languages denounced as bad than in
languages proclaimed wonderful — much more. — Bjarne Stroustrup,
from The Design and Evolution of C++
Programs must be written for people to read, and only incidentally for
machines to execute. — Harold Abelson and Gerald Jay Sussman,
computer scientists and authors, from The Structure and Interpretation of Computer Programs
Real programmers don't comment their code. If it was hard to write, it should be hard to understand. — unknown
Simplicity is prerequisite for reliability. — Edsger Dijkstra
The C programming language — a language which combines the flexibility
of assembly language with the power of assembly language. — unknown
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, object-oriented programming expert
at Bell Labs
The important point is that the cost of adding a feature isn't just the
time it takes to code it. The cost also includes the addition of an
obstacle to future expansion. Sure, any given feature list can be
implemented, given enough coding time. But in addition to coming out
late, you will usually wind up with a codebase that is so fragile that
new ideas that should be dead-simple wind up taking longer and longer to
work into the tangled existing web. The trick is to pick the features
that don't fight each other. — John Carmack, computer game programmer
The key to performance is elegance, not battalions of special cases. The
terrible temptation to tweak should be resisted unless the payoff is
really noticeable. — Jon Bently and M. Douglas McIlroy, both
computer scientists at Bell Labs
The last good thing written in C was Franz Schubert's Symphony Number 9. — Erwin Dieterich, programmer
The problem with using C++ … is that there's already a strong tendency
in the language to require you to know everything before you can do
anything. — Larry Wall, developer of the Perl language
The sooner you start to code, the longer the program will take. — Roy Carlson, University of Wisconsin
The value of a prototype is in the education it gives you, not in the code itself. — Alan Cooper, software author, from The Inmates are Running the Asylum
There are only two kinds of programming languages: those people always bitch about and those nobody uses. — Bjarne Stroustrup
There are two ways of constructing a software design. One way is to make
it so simple that there are obviously no deficiencies. And the other
way is to make it so complicated that there are no obvious deficiencies.
— Charles Antony Richard Hoare
Ugly programs are like ugly suspension bridges: they're much more liable
to collapse than pretty ones, because the way humans (especially
engineer-humans) perceive beauty is intimately related to our ability to
process and understand complexity. A language that makes it hard to
write elegant code makes it hard to write good code. — Eric S.
Raymond
Weeks of programming can save you hours of planning. — unknown
When a programming language is created that allows programmers to
program in simple English, it will be discovered that programmers cannot
speak English. — unknown
