I friend of mine recently referred to Joel as "A pompous, opinionated windbag". Which raised a laugh, I must say, but it isn't really fair. Joel's writing varies between the insightful and the frankly flaky, it's true, but I think that the former predominates.

In Biculturalism, he sums up the differences between the Windows and Unix cultures with: "Unix culture values code which is useful to other programmers, while Windows culture values code which is useful to non-programmers".

He was prompted to think about this while reading Eric S. Raymond's excellent The Art of UNIX Programming. ESR can be rather flaky himself at times - he's a gun nut, for one thing, and we really don't see his point on this side of the pond. But on technical issues his judgement is superb. We already knew that he likes Python. In The Art of UNIX Programming, we see him give an overview of Python and Java, amongst other languages. He's pretty fair, I'd say, but his preference is clear.
