Well, the HowVideoCardsWork page hasn't been updated yet and isn't complete. PCIe and aperturesbare missing. But that doesn't mean I can't learn it. Would it be wise to learn it, or only of I wanted to study history?

I read the diff/sdiff/diff3 info page. Just to compare file differences... KDE has a nice file differences compare app as part of Kdevelop, which might be easyer for me (I think in visuals and not in a logical order, if you know what I mean ).

I have 'studied' some history of X (x386, xfree86, accelerated-x, xsun, X.org) and wondered if I, next to OpenGL and Gallium, have to worry about the Open Group X spec? Or is that X.org today?
