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

Humans differ from animals to the degree that they are not merely an end result of their conditioning, but are able to reflect on their experiences and strategies, and apply insight to make changes in the way they live to modify the outcome. -- SlideTrombone (comment on "Programming can ruin your life")

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 culture code.

Before software can be reusable it first has to be usable. -- Ralph Johnson

It is said that the real winner is the one who lives in today but able to see tomorrow. -- Juan Meng, Reviewing "The future of ideas" by Lawrence Lessig

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. -- [A comment on a blog]

We become what we think about. –Earl Nightingale

15.Life is 10% what happens to me and 90% of how I react to it. –Charles Swindoll

I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed. –Michael Jordan

It is not what you do for your children, but what you have taught them to do for themselves, that will make them successful human beings. –Ann Landers
