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.

What Paul does, and does very well, is to take ideas and concepts that

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.

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.

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.

And if you go too far up, abstraction-wise, you run out of oxygen.

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.

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

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.

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.

Humans aren't rational -- they rationalize. And I don't just mean "some

driver's seat -- instead it operates after the fact, generating
rationalizations and excuses for our behavior.

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

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.

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.

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.

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

-- Gary Kildall (inventor of CP/M, one of the first OS for the micro).
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
