Rushing to optimize before the bottlenecks are known may be the only error to have ruined more designs than feature creep. From tortured code to incomprehensible data layouts, the results of obsessing about speed or memory or disk usage at the expense of transparency and simplicity are everywhere. They spawn innumerable bugs and cost millions of man-hours - often, just to get marginal gains in the use of some resource much less expensive than debugging time

It is widely grokked that cats have the hacker nature

Grovelling is not a substitute for doing your homework.

When I hear the words "social responsibility," I want to reach for my gun.

In the U.S., blacks are 12% of the population but commit 50% of violent crimes; can anyone honestly think this is unconnected to the fact that they average 15 points of IQ lower than the general population? That stupid people are more violent is a fact independent of skin color.

Any tool should be useful in the expected way, but a truly great tool lends itself to uses you never expected.

We hackers are a playful bunch; we'll hack anything, including language, if it looks like fun (thus our tropism for puns). Deep down, we like confusing people who are stuffier and less mentally agile than we are, especially when they're bosses. There's a little bit of the mad scientist in all hackers, ready to discombobulate the world and flip authority the finger - especially if we can do it with snazzy special effects.
