Programming Quote




The management question, therefore, is not whether to build a pilot system and throw it away. You will do that. The only question is whether to plan in advance to build a throwaway, or to promise to deliver the throwaway to customers.
Frederick P. Brooks

The browser is a really hostile programming environment.
Douglas Crockford, The JavaScript Programming Language (video lecture)

I feel very comfortable talking in nanoseconds. I sit at one of these analyzers and nanoseconds are wide. I mean, you can see them go by. “Jesus,” I say, “that signal takes twelve nanoseconds to get from there to there.” Those are real big things to me when I’m building a computer. Yet when I think about it, how much longer it takes to snap your fingers, I’ve lost track of what a nanosecond really means.” He paused. “Time in a computer is an interesting concept.”
The Soul of a New Machine

The fix for the Psychic Paper bug: originally, the problem occurred because Apple had four XML parsers in the OS, so, surprisingly, the fix was to add a fifth one.
Ivan Fratric, Project Zero

Walking on water and developing software from a specification are easy if both are frozen.
Edward V Berard

Yuan-Ma said, ‘When you cut against the grain of the wood, much strength is needed. When you program against the grain of a problem, much code is needed.

The trouble with programmers is that you can never tell what a programmer is doing until it’s too late.
Seymour Cray

They don't make bugs like Bunny anymore.
Olav Mjelde

A C program is like a fast dance on a newly waxed dance floor by people carrying razors.
Waldi Ravens

Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live.
Rick Osborne

Well, Mr. Frankel, who started this program, began to suffer from the computer disease that anybody who works with computers now knows about. It's a very serious disease and it interferes completely with the work. The trouble with computers is you *play* with them. They are so wonderful. You have these switches – if it's an even number you do this, if it's an odd number you do that – and pretty soon you can do more and more elaborate things if you are clever enough, on one machine.

After a while the whole system broke down. Frankel wasn't paying any attention; he wasn't supervising anybody. The system was going very, very slowly – while he was sitting in a room figuring out how to make one tabulator automatically print arc-tangent X, and then it would start and it would print columns and then bitsi, bitsi, bitsi, and calculate the arc-tangent automatically by integrating as it went along and make a whole table in one operation.

Absolutely useless. We *had* tables of arc-tangents. But if you've ever worked with computers, you understand the disease – the *delight* in being able to see how much you can do. But he got the disease for the first time, the poor fellow who invented the thing.
Richard Feynman, Surely You're Joking, Mr. Feynman!: Adventures of a Curious Character

I have always wished for my computer to be as easy to use as my telephone; my wish has come true because I can no longer figure out how to use my telephone.

The computer programmer is a creator of universes for which he alone is the lawgiver. No playwright, no stage director, no emperor, however powerful, has ever exercised such absolute authority to arrange a stage or field of battle and to command such unswervingly dutiful actors or troops.
Joseph Weizenbaum

Any politician caught spouting off about back doors is unfit for office anywhere but Hogwarts, which is also the only educational institution whose computer science department believes in “golden keys” that only let the right sort of people break your encryption.

Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems.
Jamie Zawinski alt.religion.emacs

When the wireless age arrived – and wireless telephony will soon be added to wireless telegraphy – our air will be so charged with electricity that human beings will feel its influence in a hundred different ways. Already it seems to have attacked our teeth. Tomorrow we may find, that our hair is dropping out from the same cause, and eventually it may deprive us of our senses and even our lives.

the only course for us to pursue will be to wear insulated garments to protect us. This garment will take the form of a rubber coat, with a helmet of the same material. The entire face will have to be kept covered, goggles being provided for the purpose of sight, and an air valve for breathing purposes.
Rolf Hensingmüller – The Atlanta Constitution, 30. April 1911

Ever since the first computers, there have always been ghosts in the machine. Random segments of code that have grouped together to form unexpected protocols. Unanticipated, these free radicals engender questions of free will, creativity, and even the nature of what we might call the soul.
Dr. Isaac Asimov

I have always found that plans are useless, but planning is indispensable.
Dwight D. Eisenhower

When digital transform is done correctly, it's like a caterpillar turning into a butterfly, but when done wrong, all you have is a very fast caterpillar.
George Westerman

Below the surface of the machine, the program moves. Without effort, it expands and contracts. In great harmony, electrons scatter and regroup. The forms on the monitor are but ripples on the water. The essence stays invisibly below.
Master Yuan-Ma, The Book of Programming

99 little bugs in the tracker, 99 little bugs. Take one down, patch it around, 175 bugs in the tracker!

98.5% of all statistics are made up on the spot.

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

Mostly, when you see programmers, they aren’t doing anything. One of the attractive things about programmers is that you cannot tell whether or not they are working simply by looking at them. Very often they’re sitting there seemingly drinking coffee and gossiping, or just staring into space. What the programmer is trying to do is get a handle on all the individual and unrelated ideas that are scampering around in his head.
Charles M. Strauss

Deleted code is debugged code.
Jeff Sickel

What I cannot build, I do not understand.
Richard Feynman

The use of COBOL cripples the mind; its teaching should therefore be regarded as a criminal offense.
E.W. Dijkstra

You see, programmers tend to be arrogant, self-absorbed introverts. We didn’t get into this business because we like people. Most of us got into programming because we prefer to deeply focus on sterile minutia, juggle lots of concepts simultaneously, and in general prove to ourselves that we have brains the size of a planet, all while not having to interact with the messy complexities of other people.
Robert C Martin

So much complexity in software comes from trying to make one thing do two things.
Ryan Singer

A language that doesn't affect the way you think about programming is not worth knowing.
Alan Perlis

In the one and only true way. The object-oriented version of 'Spaghetti code' is, of course, 'Lasagna code'. (Too many layers).

Hofstadter’s Law: It always takes longer than you expect, even when you take into account Hofstadter’s Law.
Douglas Hofstadter

Base 8 is just like base 10. If you are missing two fingers.
Tom Lehrer

It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years.
John Von Neumann, circa 1949

I think Microsoft named .Net so it wouldn’t show up in a Unix directory listing.

A blurry cellphone photo of an error on the screen, imported to the computer via emailing it to themselves, pasted sideways into a word document and emailed to the helpdesk address.

Software sucks because users demand it to.
Nathan Myhrvold

Shor's factoring algorithm is a large, dry, stale, and weighty fruitcake recipe of classical number theory – embedded with the hard candied citron of Euclid's greates common divisor algorithm and the bitter brazil nuts of the chinese remainder theory – that is then delightfully iced with a bit of light and fluffy quantum frosting.
Johnathan Dowling

Girls practically invented programming,” she said. “Jean Bartik, Marlyn Wescoff, Fran Bilas—they all programmed ENIAC.” I had no idea what she was talking about. “And don’t forget Margaret Hamilton. She wrote the software that let Apollo 11 land on the moon.” “I meant programming video games,” I said. “Dona Bailey, Centipede. Brenda Romero, Wizardry. Roberta Williams, King’s Quest. She designed her first computer game at the kitchen table. I interviewed her for school last year.
Jason Rekulak, The Impossible Fortress

Remember that there is no code faster than no code.
Taligent's Guide to Designing Programs

Measuring programmer productivity by lines of code is like measuring aircraft by weight.
Bill Gates

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 and P.J. Plauger, The Elements of Programming Style

Any fool can use a computer. Many do.
Ted Nelson

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the universe trying to build bigger and better idiots. So far, the universe is winning.
Rick Cook

Every methodology I’ve come across has, at its kernel, a very small section labelled “do magic here”.

The Mandelbrot set is the Radiohead of fractals
Dr. Tom Murphy VII Ph.D.

A programmer was arrested for writing unreadable code. He refused to comment.

The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination.
Frederick P. Brooks

If you want to get it smooth, you’ve got to rewrite it from scratch at least five times
Bill Atkinson

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

Integer a = 127;
Integer b = 127;
System.out.println(a==b); // true
// but
Integer a = 128;
Integer b = 128;
System.out.println(a==b); // false


'foo' == TRUE
'foo' == 0
TRUE != 0.


The things we read watch us read them. The things we listen to, listen to us listen to them. We are tracked, we are monitored, we are predicted by the media we use… our media consume us
Eben Moglen

It is easy to say that a piece of code is badly written. It is easy to complain or even laugh. But the question is: are you good enough to make it better?
Sandro Mancuso


Portability is for canoes.
Jim McCarthy, Dynamics of Software Development

FTP is a legacy technology, and legacy technologies are like herpes: you might have had fun when it was getting installed, you probably went years without thinking about it, but when it goes wrong you regret everything, and you are never going to get rid of it.

A distributed system is one in which the failure of a computer you didn’t even know existed can render your own computer unusable.
Leslie Lamport

If it doesn’t work, it doesn’t matter how fast it doesn’t work.
Mich Ravera

There is an obvious resemblance between an unreadable script and a secret code; similar methods can be employed to break both. But the differences must not be overlooked. The code is deliberately designed to baffle the investigator; the script is only puzzling by accident.
John Chadwick, The Decipherment of Linear B

Programmers have their own form of latrinalia: code comments. They're frequently vulgar, they're sometimes comprehensible only to the person who wrote them, and we all like to pretend that they're more meaningful than they are.
Remy Porter

My code has advanced beyond me
Joe Barnard

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

The generation of random numbers is too important to be left to chance.
Robert R. Coveyou

The future lies in designing and selling computers that people don't realize are computers at all.Adam Osborne

Debugging time increases as a square of the program’s size.
Chris Wenham

Clean code always looks like it was written by someone who cares.
Robert C Martin

When I was running a software company, we always knew it would take one great programmer to solve a hard problem in one night versus 10 mediocre programmers taking a month to screw up a problem even worse.
James Altucher, Reinvent Yourself

When the Lisa team was pushing to finalize their software in 1982, project managers started requiring programmers to submit weekly forms reporting on the number of lines of code they had written. Bill Atkinson thought that was silly. For the week in which he had rewritten QuickDraw’s region calculation routines to be six times faster and 2000 lines shorter, he put “-2000″ on the form. After a few more weeks the managers stopped asking him to fill out the form, and he gladly complied.

If you want to lose weight, don’t buy a new scale; change your diet. If you want to improve your software, don’t test more; develop better.
Steve McConnell Code Complete

Haskell is faster than C++, more concise than Perl, more regular than Python, more flexible than Ruby, more typeful than C#, more robust than Java, and has absolutely nothing in common with PHP.

And that, by the way, is the cure for imposter syndrome: realize that the world is full of successful morons, so no matter how much of a moron you think you are, you're entitled to whatever success you have.
Remy Porter

Sorry, I can't do that Dave.

Documentation is like term insurance: It satisfies because almost no one who subscribes to it depends on its benefits.
Alan J Perlis

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.
C.A.R. Hoare, 1980 ACM Turing Award Lecture

Man muss sich das wie einen Dreijährigen vorstellen, der sich jede Klasse in den Mund steckt, um herauszufinden, wie sie schmeckt und ob sie sich ausführen lässt.

I know that I am typing these words on a device of staggering computational power; a device such as Lovelace dreamt of, such as Leibniz thirsted for, such as Poincaré would have chainsawed his thumbs to possess; a device that promises to transform mathematics and the world.

A device that I use mostly for word processing.

When you're designing for extremes with software, the three most important "extremes" to remember are:
1. Design for people who can't read.
2. Design for people who can't use a mouse.
3. Design for people who have such bad memories they would forget their own name if it weren't embossed on their American Express
Joel Spolsky, User Interface Design for Programmers

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

A program that produces incorrect results twice as fast is infinitely slower.
John Osterhout

One of my most productive days was throwing away 1000 lines of code.
Ken Thompson

The best programs are written so that computing machines can perform them quickly and so that human beings can understand them clearly. A programmer is ideally an essayist who works with traditional aesthetic and literary forms as well as mathematical concepts, to communicate the way that an algorithm works and to convince a reader that the results will be correct.
Donald E Knuth, Selected Papers on Computer Science

Incorrect documentation is often worse than no documentation.
Bertrand Meyer

Simplicity is the ultimate sophistication.

You Can't Write Perfect Software. Did that hurt? It shouldn't. Accept it as an axiom of life. Embrace it. Celebrate it. Because perfect software doesn't exist. No one in the brief history of computing has ever written a piece of perfect software. It's unlikely that you'll be the first. And unless you accept this as a fact, you'll end up wasting time and energy chasing an impossible dream.
Andrew Hunt

How many software developers does it take to change a lightbulb? None, it's a hardware problem.
Laura Griffin, Deep Dark

In programming the hard part isn’t solving problems, but deciding what problems to solve.
Paul Graham

Tzu-li and Tzu-ssu were boasting about the size of their latest programs. ‘Two-hundred thousand lines,’ said Tzu-li, ‘not counting comments!’ Tzu-ssu responded, ‘Pssh, mine is almost a million lines already.’ Master Yuan-Ma said, ‘My best program has five hundred lines.’ Hearing this, Tzu-li and Tzu-ssu were enlightened.
