No, and no. The data structure described by Henning-Kamp is not a B-tree, but a heap. Additionally, it's cache-aware, not cache-oblivious.

...and I hope I'm not the only one. I actually use Yahoo Shopping on a regular basis, but if Yahoo were acquired by Microsoft I'd stop immediately, and find an alternate vendor-aggregator. Just a matter of principle (and maybe as much aesthetic as anything), but Microsoft just icks me out.

Kinda funny because it troubles me little to support an empire which would probably be just as evil if it had the same amount of power, Apple's. But Apple has an aesthetic sense, and has thus slipped perhaps-irrationally behind my defenses.

This whole Yahoo mess is also a fine example of the downside of going public -- you have amoral raiders screaming the battlecry "shareholder value" and using that to bludgeon anyone in a company who makes a principled decision which might not maximize stock prices in the short term.

(Mod me +2/-1 incoherent?)
