Don't worry about what anybody else is going to do. The best way to
predict the future is to invent it.
-- Alan Kay

Premature optimization is the root of all evil (or at least most of it)
in programming.
-- Donald Knuth

Lisp has jokingly been called "the most intelligent way to misuse a
computer". I think that description is a great compliment because it
transmits the full flavor of liberation: it has assisted a number of our
most gifted fellow humans in thinking previously impossible thoughts.
-- Edsger Dijkstra, CACM, 15:10

Keep away from people who try to belittle your ambitions. Small people
always do that, but the really great make you feel that you, too, can
become great.
-- Mark Twain

What Paul does, and does very well, is to take ideas and concepts that
are beautiful in the abstract, and brings them down to a real world
level. That's a rare talent to find in writing these days.
-- Jeff "hemos" Bates, Director, OSDN; Co-evolver, Slashdot

Since programmers create programs out of nothing, imagination is our
only limitation. Thus, in the world of programming, the hero is the one
who has great vision. Paul Graham is one of our contemporary heroes. He
has the ability to embrace the vision, and to express it plainly. His
works are my favorites, especially the ones describing language design.
He explains secrets of programming, languages, and human nature that can
only be learned from the hacker experience. This book shows you his
great vision, and tells you the truth about the nature of hacking.
-- Yukihiro "Matz" Matsumoto, creator of Ruby

To follow the path:
    look to the master,
    follow the master,
    walk with the master,
    see through the master,
    become the master.

Fools ignore complexity. Pragmatists suffer it. Some can avoid it.
Geniuses remove it.
-- Alan J. Perlis (Epigrams in programming)

A year spent in artificial intelligence is enough to make one believe in
God.
-- Alan J. Perlis (Epigrams in programming)

Dealing with failure is easy: Work hard to improve. Success is also easy
to handle: You've solved the wrong problem. Work hard to improve.
-- Alan J. Perlis (Epigrams in programmi ng)

Within a computer natural language is unnatural.
-- Alan J. Perlis (Epigrams in programming)

You think you know when you learn, are more sure when you can write,
even more when you can teach, but certain when you can program.
-- Alan J. Perlis (Epigrams in programming)

Adapting old programs to fit new machines usually means adapting new
machines to behave like old ones.
-- Alan J. Perlis (Epigrams in programming)

A little learning is a dangerous thing.
-- Alexander Pope

Computer science education cannot make anybody an expert programmer any
more than studying brushes and pigment can make somebody an expert
painter.
-- Eric Raymond

Einstein argued that there must be simplified explanations of nature,
because God is not capricious or arbitrary.
-- Frederick P. Brooks, No Sliver Bullet.

Students should be evaluated on how well they can achieve the goals they
strived to achieve within a realistic context. Students need to learn to
do things, not know things.
-- Roger Schank, Engines for Education

We remember what we learn when we care about performing better and when
we believe that what we have been asked to do is representative of
reality.
-- Roger Schank, Engines for Education

There really is no learning without doing.
-- Roger Schank, Engines for Education

We really have to get over the idea that some stuff is just worth
knowing even if you never do anything with it. Human memories happily
erase stuff that has no purpose, so why try to fill up children's heads
with such stuff?
-- Roger Schank, Engines for Education

La tactique, c'est ce que vous faites quand il y a quelque chose à
faire; la stratégie, c'est ce que vous faites quand il n'y a rien à
faire.
-- Xavier Tartacover

The only problems we can really solve in a satisfactory manner are those
that finally admit a nicely factored solution.
-- E. W. Dijkstra, The humble programmer

The best way to learn to live with our limitations is to know them.
--E. W. Dijkstra, The humble programmer

This challenge, viz. the confrontation with the programming task, is so
unique that this novel experience can teach us a lot about ourselves. It
should deepen our understanding of the processes of design and creation,
it should give us better control over the task of organizing our
thoughts. If it did not do so, to my taste we should no deserve the
computer at all!  It has allready taught us a few lessons, and the one I
have chosen to stress in this talk is the following. We shall do a much
better programming job, provided that we approach the task with a full
appreciation of its tremenduous difficulty, provided that we stick to
modest and elegant programming languages, provided that we respect the
intrinsec limitations of the human mind and approach the task as Very
Humble Programmers.
-- E. W. Dijkstra, The humble programmer

Ce n'est que par les relations qu'on entretient entre nos différentes
connaissances qu'elles nous restent accessibles.
-- Shnuup, sur l'hypertexte (SELFHTML -> Introduction -> Definitions sur l'hypertexte)

We now come to the decisive step of mathematical abstraction: we forget
about what the symbols stand for. ...[The mathematician] need not be
idle; there are many operations which he may carry out with these
symbols, without ever having to look at the things they stand for.
-- Hermann Weyl, The Mathematical Way of Thinking

An expert is, according to my working definition "someone who doesn't
need to look up answers to easy questions".
-- Eric Lippert.

The programmer must seek both perfection of part and adequacy of
collection.
-- Alan J. Perlis

Thus, programs must be written for people to read, and only incidentally
for machines to execute.
-- Alan J. Perlis

We control complexity by building abstractions that hide details when
appropriate. We control complexity by establishing conventional
interfaces that enable us to construct systems by combining standard,
well-understood pieces in a ``mix and match'' way. We control complexity
by establishing new languages for describing a design, each of which
emphasizes particular aspects of the design and deemphasizes others.
-- Alan J. Perlis

The acts of the mind, wherein it exerts its power over simple ideas, are
chiefly these three: 1. Combining several simple ideas into one compound
one, and thus all complex ideas are made. 2. The second is bringing two
ideas, whether simple or complex, together, and setting them by one
another so as to take a view of them at once, without uniting them into
one, by which it gets all its ideas of relations. 3. The third is
separating them from all other ideas that accompany them in their real
existence: this is called abstraction, and thus all its general ideas
are made.
-- John Locke, An Essay Concerning Human Understanding (1690)

Lisp programmers know the value of everything but the cost of nothing.
-- Alan J. Perlis

An interpreter raises the machine to the level of the user program; a
compiler lowers the user program to the level of the machine language.
-- SICP

Everything should be made as simple as possible, but no simpler.
-- Albert Einstein

The great dividing line between success and failure can be expressed in
five words: "I did not have time."
-- WestHost weekly newsletter 14 Feb 2003

When your enemy is making a very serious mistake, don't be impolite and
disturb him.
-- Napoleon Bonaparte (allegedly)

A charlatan makes obscure what is clear; a thinker makes clear what is
obscure.
-- Hugh Kingsmill

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. The
first method is far more difficult.
-- C. A. R. Hoare

And if you go too far up, abstraction-wise, you run out of oxygen.
Sometimes smart thinkers just don't know when to stop, and they create
these absurd, all-encompassing, high-level pictures of the universe that
are all good and fine, but don't actually mean anything at all.
-- Joel Spolsky		

The three chief virtues of a programmer are: Laziness, Impatience and
Hubris.
-- Larry Wall (Programming Perl)

All non-trivial abstractions, to some degree, are leaky.
-- Joel Spolsky (The Law of Leaky Abstractions)

XML wasn't designed to be edited by humans on a regular basis.
-- Guido van Rossum

Premature abstraction is an equally grevious sin as premature
optimization.
-- Keith Devens

You can have premature generalization as well as premature optimization.
-- Bjarne Stroustrup

He causes his sun to rise on the evil and the good, and sends rain on
the righteous and the unrighteous.
-- Matthew 5:45

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

Je n'ai fait celle-ci plus longue que parce que je n'ai pas eu le loisir
de la faire plus courte. (I have made this letter so long only because I
did not have the leisure to make it shorter.)
-- Blaise Pascal (Lettres Provinciales)

Men never do evil so completely and cheerfully as when they do it from
religious conviction.
-- Blaise Pascal (attributed)

Everybody makes their own fun. If you don't make it yourself, it ain't
fun -- it's entertainment.
-- David Mamet (as relayed by Joss Whedon)

If we wish to count lines of code, we should not regard them as *lines
produced* but as *lines spent*.
-- Edsger Dijkstra		

Sometimes a man with too broad a perspective reveals himself as having
no real perspective at all. A man who tries too hard to see every side
may be a man who is trying to avoid choosing any side. A man who tries
too hard to seek a deeper truth may be trying to hide from the truth he
already knows.  That is not a sign of intellectual sophistication and
"great thinking". It is a demonstration of moral degeneracy and
cowardice.
-- Steven Den Beste

Omit needless words.
-- William Strunk, Jr. (The Elements of Style)

I have never met a man so ignorant that I couldn't learn something from
him.
-- Galileo Galilei

A society that puts equality -- in the sense of equality of outcome --
ahead of freedom will end up with neither equality nor freedom. The use
of force to achieve equality will destroy freedom, and the force,
introduced for good purposes, will end up in the hands of people who use
it to promote their own interests.
-- Milton Friedman (Thomas Sowell: A Conflict of Visions, p130)

Philosophy: the finding of bad reasons for what one believes by
instinct.
-- Brave New World (paraphrased)

Of all tyrannies a tyranny sincerely exercised for the good of its
victims may be the most oppressive. It may be better to live under
robber barons than under omnipotent moral busybodies, The robber baron's
cruelty may sometimes sleep, his cupidity may at some point be satiated;
but those who torment us for own good will torment us without end, for
they do so with the approval of their own conscience.
-- C.S. Lewis

Fools! Don't they know that tears are a woman's most effective weapon?
-- Catwoman (The Batman TV Series, episode 83)

It's like a condom; I'd rather have it and not need it than need it and

The reason to do animation is caricature. Good caricature picks out the
essense of the statement and removes everything else. It's not simply
about reproducing reality; It's about bumping it up.

Lisp is worth learning for the profound enlightenment experience you
will have when you finally get it; that experience will make you a
better programmer for the rest of your days, even if you never actually
use Lisp itself a lot.
-- Eric S. Raymond

Any sufficiently complicated C or Fortran program contains an ad hoc,
informally specified, bug-ridden, slow implementation of half of Common
Lisp.
-- Philip Greenspun (Greenspun's Tenth Rule)

I was talking recently to a friend who teaches at MIT. His field is hot
now and every year he is inundated by applications from would-be
graduate students. "A lot of them seem smart," he said. "What I can't

The direct pursuit of happiness is a recipe for an unhappy life.
-- Donald Campbell

It's no trick for talented people to be interesting, but it's a gift to
be interested. We want an organization filled with interested people.
-- Randy S. Nelson (dean of Pixar University)

Why teach drawing to accountants? Because drawing class doesn't just
teach people to draw. It teaches them to be more observant. There's no

While I’ve always appreciated beautiful code, I share Jonathan’s concern
about studying it too much. I think studying beauty in music and
painting has led us to modern classical music and painting that the
majority of us just don’t get. Beauty can be seen when it emerges, but
isn’t something to strive for in isolation of a larger context. In the
software world, the larger context would be the utility of the software
to the end user.

To do something well you have to love it. So to the extent you can
preserve hacking as something you love, you're likely to do it well. Try
to keep the sense of wonder you had about programming at age 14. If
you're worried that your current job is rotting your brain, it probably
is.

What I didn't understand was that the value of some new acquisition
wasn't the difference between its retail price and what I paid for it.
It was the value I derived from it. Stuff is an extremely illiquid
asset. Unless you have some plan for selling that valuable thing you got
so cheaply, what difference does it make what it's "worth?" The only way
you're ever going to extract any value from it is to use it. And if you
don't have any immediate use for it, you probably never will.
-- Paul Graham

Only bad designers blame their failings on the users.

Humans aren't rational -- they rationalize. And I don't just mean "some
of them" or "other people". I'm talking about everyone. We have a "logic
engine" in our brains, but for the most part, it's not the one in the
driver's seat -- instead it operates after the fact, generating
rationalizations and excuses for our behavior.
-- Paul Buchheit

What do Americans look for in a car? I've heard many answers when I've
asked this question. The answers include excellent safety ratings, great
gas mileage, handling, and cornering ability, among others. I don't
believe any of these. That's because the first principle of the Culture
Code is that the only effective way to understand what people truly mean
is to ignore what they say. This is not to suggest that people
intentionally lie or misrepresent themselves. What it means is that,
when asked direct questions about their interests and preferences,
people tend to give answers they believe the questioner wants to hear.
Again, this is not because they intend to mislead. It is because people
respond to these questions with their cortexes, the parts of their
brains that control intelligence rather than emotion or instinct. They
ponder a question, they process a question, and when they deliver an
answer, it is the product of deliberation. They believe they are telling
the truth. A lie detector would confirm this. In most cases, however,
they aren't saying what they mean.

The lesson of the story might appear to be that self-interested and
ambitious people in power are often the cause of wastefulness in
developing countries. But self-interested and ambitious people are in
positions of power, great and small, all over the world. In many places,
they are restrained by the law, the press, and democratic opposition.
Cameroon's tragedy is that there is nothing to hold self-interest in
check.
-- Tim Harford

To solve your problems you must learn new skills, adapt new thought
patterns, and become a different person than you were before that
problem.  God has crafted you for success. In the middle of every
adversity lie your best opportunities. Discover it, build upon it and
move forward in your journey to live an extraordinary life.  You owe it
to yourself to live a great life. Don’t let negative thoughts pull you
down. Be grateful and open to learn and grow.

Having large case statements in an object-oriented language is a sure

Being a programmer is the same way. The only way to be a good programmer
is to write code. When you realize you haven't been writing much code
lately, and it seems like all you do is brag about code you wrote in the
past, and people start looking at you funny while you're shooting your
mouth off, realize it's because they know. They might not even know they
know, but they know. So, yes, doing what you love brings success, and by
all means, throw yourself a nice big party, buy yourself a nice car,
soak up the adulation of an adoring crowd. Then shut the fuck up and get
back to work.
-- Sincerity Theory

Another feature about this guy is his low threshold of boredom. He'll
pick up on a task and work frantically at it, accomplishing wonders in a
short time and then get bored and drop it before its properly finished.
He'll do nothing but strum his guitar and lie around in bed for several
days after.  Thats also part of the pattern too; periods of frenetic
activity followed by periods of melancholia, withdrawal and inactivity.
This is a bipolar personality.

My dream is that people adopt it on its own merits. We're not trying to
bend Ruby on Rails to fit the enterprise, we're encouraging enterprises
to bend to Ruby on Rails. Come if you like it, stay away if you don't.
We're not going head over heels to accommodate the enterprise or to lure
them away from Java. That's how you end up with Java, if you start
bending to special interest groups.
-- David Heinemeier Hansson (Ruby On Rails' creator)

New eyes have X-ray vision.  [someone that hasn't written it is more

So - what are the most important problems in software engineering? I’d
answer “dealing with complexity”.

So the mere constraint of staying in regular contact with us will push
you to make things happen, because otherwise you'll be embarrassed to

The choice of the university is mostly important for the piece of paper

Humans differ from animals to the degree that they are not merely an end

Abstraction is a form of data compression: absolutely necessary, because
human short-term memory is so small, but the critically important aspect

Have you ever noticed that when you sit down to write something, half
the ideas that end up in it are ones you thought of while writing it?
The same thing happens with software. Working to implement one idea

In general, we can think of data as defined by some collection of

Mastering isn’t a survival instinct; it’s an urge to excel. Mastering is
one of the experiences that delineates us from animals. It is striving
to be more tomorrow than we are today; to perfectly pitch the ball over
home plate; to craft the perfect sentence in an article; to open the
oven and feel the warm, richly-scented cloud telling you dinner is going
to be absolutely extraordinary. We humans crave perfection, to be
masters of our domain, to distinguish ourselves by sheer skill and
prowess.

Let me try to get this straight: Lisp is a language for describing
algorithms. This was JohnMcCarthy's original purpose, anyway: to build
something more convenient than a Turing machine. Lisp is not about file,
socket or GUI programming - Lisp is about expressive power. (For
example, you can design multiple object systems for Lisp, in Lisp. Or
implement the now-fashionable AOP. Or do arbitrary transformations on
parsed source code.) If you don't value expressive power, Lisp ain't for
you. I, personally, would prefer Lisp to not become mainstream: this
would necessarily involve a dumbing down.

Opportunities that present themselves to you are the consequence -- at
least partially -- of being in the right place at the right time. They
tend to present themselves when you're not expecting it -- and often
when you are engaged in other activities that would seem to preclude you
from pursuing them. And they come and go quickly -- if you don't jump
all over an opportunity, someone else generally will and it will vanish.
-- Marc Andreessen (http://blog.pmarca.com/)

I think that a lot of programmers are ignoring an important point when
people talk about reducing code repetition on large projects.
Part of the idea is that large projects are intrinsically *wrong*. That
you should be looking at making a number of smaller projects that are

projects elsewhere.

Getting back to failing early, I've learned it's important to completely
fail. Get fired. Shoot the project, then burn its corpse. Melt the CVS

Something Confusing about "Hard":
It's tempting to think that if it's hard, then it's valuable.

The venerable master Qc Na was walking with his student, Anton.  Hoping to
prompt the master into a discussion, Anton said "Master, I have heard that
objects are a very good thing - is this true?"  Qc Na looked pityingly at
his student and replied, "Foolish pupil - objects are merely a poor man's
closures."
    Chastised, Anton took his leave from his master and returned to his cell,
intent on studying closures.  He carefully read the entire "Lambda: The
Ultimate..." series of papers and its cousins, and implemented a small
Scheme interpreter with a closure-based object system.  He learned much, and
looked forward to informing his master of his progress.
    On his next walk with Qc Na, Anton attempted to impress his master by
saying "Master, I have diligently studied the matter, and now understand
that objects are truly a poor man's closures."  Qc Na responded by hitting
Anton with his stick, saying "When will you learn? Closures are a poor man's
object."  At that moment, Anton became enlightened.

I think it is wise, and only honest, to warn you that my goal is
immodest. It is not my purpose to "transfer knowledge" to you that,
subsequently, you can forget again. My purpose is no less than to
effectuate in each of you a noticeable, irreversable change. I want you
to gain, for the rest of your lives, the insight that beautiful proofs
are not "found" by trial anf error but are the result of a consciously
applied design discipline. I want you to raise your quality standards. I
mean, if 10 years from now, when you are doing something quick and
dirty, you suddenly visualize that I am looking over your shoulders and
say to yourself "Dijkstra would not have liked this", well, that would
be enough immortality for me.

Well, if you talk about programming to a group of programmers who use
the same language, they can become almost evangelistic about the
language. They form a tight-knit community, hold to certain beliefs, and
follow certain rules in their programming. It’s like a church with a
programming language for a Bible.
-- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

It’s a problem if the design doesn’t let you add features at a later
date. If you have to redo a program, the hours you spend can cause you
to lose your competitive edge. A flexible program demonstrates the
difference between a good designer and someone who is just getting a
piece of code out.
-- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

[How friendly will this machine be?] Well, I don’t think it’s a matter
of friendliness, because ultimately if the program is going to
accomplish anything of value, it will probably be relatively complex.
-- Gary Kildall (inventor of CP/M, one of the first OS for the micro).

Some people suggest that machines would be friendlier if input could be
in a natural language. But natural language is probably the worst kind
of input because it can be quite ambiguous. The process of retrieving
information from the computer would be so time-consuming that you would
be better off spending that time getting the information directly from
an expert.

Workers of the world, the chains that bind you are not held in place by
a ruling class, a "superior" race, by society, the state, or a leader.
They are held in place by none other than yourself. Those who seek to
exploit are not themselves free, for they place no value in freedom. Who
is it that really employs you and commands you to pick up your daily
load? And who is it that you allow to pass judgment on the adequacy of
your toil? Who have you empowered to dangle the carrot before you and
threaten with disapproval? Who, when you wake each morning, sends you
off to what you call your work?
Is there an "I want to" behind all your "I have to," or have you been so
long forgotten to yourself that "I want" exists only as an idea in your
head? If you have disconnected from your soul's desire and are drowning
in an ocean of "have to," then rise up and overthrow your master. Begin
