A non negative binary integer value x is a power of 2 iff (x & (x-1)) is 0 using 2's complement arithmetic. -- [fact]

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. -- E. W. Dijkstra, The humble programmer

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]

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
