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

The only thing a man should ever be 100% convinced of is his own ignorance. -- DJ MacLean

In theory, there’s no difference between theory and practice. But in practice, there is. -- Albert Einstein

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. -- Max Levchin, PayPal founder, Talk at StartupSchool2007

1 - Creativity and innovation always build on the past. 2 - The past always tries to control the creativity that builds on it. 3 - Free societies enable the future by limiting the past. 4 - Ours is less and less a free society. -- Lawrence Lessig, Free Culture.

In OO, it's the data that is the "important" thing: you define the class which contains member data, and only incidentally contains code for manipulating the object. In FP, it's the code that's important: you define a function which contains code for working with the data, and only incidentally define what the data is. -- almkgor, on reddit

When I stand before God at the end of my life, I would hope that I would not have a single bit of talent left and could say, I used everything you gave me. –Erma Bombeck

Take up one idea. Make that one idea your life — think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success. ~Swami Vivekananda

Strive not to be a success, but rather to be of value. –Albert Einstein

Success does not consist in never making mistakes but in never making the same one a second time. ~George Bernard Shaw
