New Best Way To Nuke a Short-Notice Asteroid

ekc What about comets? (311 comments)

I realize asteroids are much more numerous in the inner solar system, but we're getting better at tracking them so we would ideally have a longer lead time to deal with any threat. Comets, on the other hand, tend to come out of nowhere, so the short notice scenario is much more likely.

The Most Expensive One-Byte Mistake

ekc Encoding length (594 comments)

A C string can be as long as you want and never requires more than length+1 bytes of storage. A length+data scheme would need unlimited lengths to be as flexible with preferably a 1-byte overhead for short strings at least. I guess you could do something UTF-8-ish and add extra length bytes as needed for longer strings, but then you'd need a formula to figure out how much storage the string would require. Sounds a little messy to me.

Facebook Taking On Apple?

ekc The trouble with FB apps... (127 comments)

...is that the vast majority of them are written for flash. It remains to be seen if an iOS store will get developers to redo them all.

How Apple's iOS Went From Insecure To Most Secure

ekc OS X security features (312 comments)

FTA: By comparison, Mac OS X has limited application-dependent sandboxing and no code signing, and it only partially implements ASLR.

I was under the impression OS X has had code signing since Leopard, though it's voluntary and not heavily adopted by third parties so far from the looks of it. Also, I noticed a slide in the WWDC 2011 keynote where application sandboxing was listed as a feature of Lion.

US Objects To the Kilogram

ekc While we're at it (538 comments)

Could someone explain to me why people always speak of the kilogram as the standard unit of mass and not the gram?

Capturing Carbon With Garbage Heaps

ekc Soil degradation? (186 comments)

If you keep removing all the plant waste from a farm and burying it elsewhere, wouldn't this deplete the soil of nutrients? I'm not a farmer, but I have to wonder.

5.5 Earthquake Hits Canada; Felt in US Midwest, New England

ekc Re:5.5? Feh! (560 comments)

What a bunch of wimps.

Here in southern California, a mere 5.5 would hardly even arouse anyone's interest. Probably make page 1 of the local section unless the Padres made a big trade; then it would be relegated to page 2.

I was in Kingston, Ont. (about 2 hours drive from the epicentre) eating my lunch on a picnic bench outside when people came rushing out of the office wide-eyed yelling, "Earthquake!" I didn't feel a thing. Honestly. If that was an earthquake, I've had bigger rumblings coming out of my stomach. Then again, I lived in Japan for a time. They know how to do earthquakes over there.

NASA's New Mission to the Moon

ekc Astronomy prospects (283 comments)

If they are seriously going back to the moon, I hope they take the opportunity to do some astronomy. Wouldn't it be a good place for experiments in higher wavelength interferometry, for example? One thing I have been wondering about is whether you could line one of the smaller craters in a wire mesh and turn it into a radio telescope? A primitive Arecibo, if you will.
