Programming in the abstract sense is what I really enjoy. I enjoy lots of different areas of it... I'm taking a great deal of enjoyment writing device drivers for Linux. I could also be having a good time writing a database manager or something because there are always interesting problems.

You can prematurely optimize maintainability, flexibility, security, and robustness just like you can performance.

Focus is a matter of deciding what things you're not going to do.

Sharing the code just seems like The Right Thing to Do. It costs us rather little, but it benefits a lot of people in sometimes very significant ways. There are many university research projects, proof of concept publisher demos, and new platform test beds that have leveraged the code. Free software that people value adds wealth to the world.

It is not that uncommon for the cost of an abstraction to outweigh the benefit it delivers. Kill one today!

Some cynical people think that every activity must revolve around the mighty dollar, and that anyone saying otherwise is just attempting to delude the public. I will probably never be able to convice them that that isn't always the case, but I do have the satisfaction of knowing that I live in a less dingy world than they do.

If you aren't sure which way to do something, do it both ways and see which works better.
