No pics of Air Force One or the President's motorcade we saw today. Sorry 'bout that, but the Secret Service does a pretty good job.
Air Force One is sitting on the tarmac at Moffett Federal Airfield as President Obama beings a West-Coast swing. I'll see about getting some pics tomorrow.
Suppose a man gives up his youth to the struggle for some coveted degree, some honour or award of the scholarly life. It is very possible that when he obtains that for which he has struggled, he may find that the joy of possession is not so great as the joy of the strife. It is part of the discipline of life that we should be educated by disillusion; we press onward to some shining summit, only to find that it is but a bastion thrown out by a greater mountain, which we did not see, and that the real summit lies far beyond us still. But are we the worse for the struggle? No; we are manifestly the better, for by whatever illusion we have been led onward, it is at least clear that without the illusion we should not have stood as high as we do.
— William James Dawson, The Making of Manhood, 1894

In just three weeks, gamers deciphered the structure of a key protein in the development of AIDS that has stumped scientists for years. According to a study published Sunday in the journal Nature Structural & Molecular Biology, the findings could present a significant breakthrough for AIDS and HIV research.Update: Ars Technica also has a good article.

Not exactly sure what I'm supposed to think about this, Marco. Also, Instapaper's down?!?!?
Right now I'd be happy with a way to keep calendar alerts from buzzing on my laptop, iPhone, and iPad all at the same time even though all three devices are sitting next to one another on my desk.
Seconded. And I don't even own an iPad.
