Some good updates on EnterpriseOne over at the JD Ewards Advisor blog.
The High Scalability blog has some links to a presentation (slides and video) on how Google deals with scaling up (as you can imagine, they do a lot of that). I hope you have better luck with the video, I gave it five minutes and it still didn't finish downloading, so it may be 'overwatched' at the moment. In a way, that's mildly amusing, considering the video isn't scaling to meet demand. But the slides downloaded fine, and are full of eminently technical material (suitable for menacing non-technical relatives, saying that 'this is really interesting stuff' and 'just sit down here and I'll explain it all in terms you can understand').
