A gloss is a marginal note (see picture in the Wikipedia entry for an example). While one can't very well annotate someone else's web page, I will add my voice to the chorus of those who have commented on Linus Torvalds coding style document.
I strongly agree with almost everything said in this document, and have been glad for the "backup" when I've had to argue a point with some of my fellow workers. There are, however, a couple of items where I diverge.
The first point that I would gently argue is that 8-space tabs are too deep. I haven't "been looking at [my] screen for 20 straight hours" for a couple of years, but at the very outset I worked with 4-space tabs, and I find them very readable. I haven't worked with anyone who has strongly defended 8-space tabs. I will admit that I have had to try to persuade people to switch from 2-space to 4-space tabs, but that was back in the Apple ][ Basic days when people were trying to keep their programs as small as possible (remember cassettes?). I don't know of any readability studies on this topic, and would be interested to see them.
My second argument (or shall I say "disagreement" to be less disagreeable...) is with his distaste for mixed-case names. I find mixed-case easier to read (maybe it's just me), but, more importantly, I find it a lot easier to type than underscores. I know I'm not the best touch-typist in the world, but I always find myself looking down to make sure that my ring-finger is indeed hitting the dash/underscore key and not one of its neighbors. Using camelCase keeps my fingers on the home row much more, makes my typing faster and reduces the number of errors.
These are just friendly disagreements, however, and don't diminish the fact that I'm glad this document exists, and is available to us all.
