Functional programming is like describing your problem to a
mathematician. Imperative programming is like giving instructions to
an idiot.

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.

Programming is the art of figuring out what you want so precisely that
even a machine can do it.

Something Confusing about "Hard":
It's tempting to think that if it's hard, then it's valuable.
Most valuable things are hard.
Most hard things are completely useless -- (picture of someone smashing
their head through concrete blocks kung-fu style).
Hard DOES NOT EQUATE TO BEING valuable.
Remember Friendster back in the day?
You'd sign in, invite friends, have 25 friends, go to their profile, and
then it'd show how you were connected to each one.
That's an impressive [some geeky CS jargon] Cone traversal of a tree -
100 million string comparisons per page -- it won't scale.
Used to take a minute per page to load, and Friendster died a painful
death.
MySpace -- not interested in solving problems
They use the shortcut of "Miss Fitzpatrick is in your extended network"
(i.e. even when you're not even signed up for MySpace)
They didn't solve the hard problem. But they make the more relevant
assumption that you want to be connected to hot women. [LOL]
Shows Alexa graph showing that in early 2005 Myspace took off, and
quickly bypassed Friendster and never looked back.

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.

That is one of the most distinctive differences between school and the
real world: there is no reward for putting in a good effort. In fact,
the whole concept of a "good effort" is a fake idea adults invented to
encourage kids. It is not found in nature.

You must always work not just within but below your means. If you can
handle three elements, handle only two. If you can handle ten, then
handle five. In that way the ones you do handle, you handle with more
ease, more mastery and you create a feeling of strength in reserve.

courage to act on what they know right now and the humility to change
course when they find better evidence.

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.
