Music Is Dead: iPods and Young People Have Utterly Destroyed Music
Music Is Dead: iPods and Young People Have Utterly Destroyed Music This is depressing for someone like me. A Stanford professor did an informal study over several years, and he found that students each year preferred low-quality MP3 more and more. Like the author, this is disappointing for me because it most likely means it…

Phew! That was close!
I’m not sure why, but I seem to be on an astronomy kick lately. I came across a little tidbit today that reminded me of Deep Impact and Armageddon. At 13:44 UT today (March 2, 2009), a 30 meter asteroid (identified as 2009 DD45) will pass by earth and miss by only 37,282 miles. Even though…

The Secret in Building 26
I just finished reading The Secret in Building 26: The Untold Story of How America Broke the Final U-boat Enigma Code. What a fascinating read! I’ve written before about the UK’s contribution to code breaking during WWII (Neglect of Bletchley condemned and Bletchley Park Update), but this is the first time I learned about some of…

Jury Duty – Epic Fail
Today, I was scheduled for Jury Duty. Actually, I was an alternate with instructions to call a number after 3:00 PM the day before. The instructions said there would be a recording to let us know whether we would be needed or not. Like a good citizen, I called the number at 3:15 PM, but…

Smallest Exoplanet Is Most Earth-like Yet | Wired Science from Wired.com This is really interesting. It’s a planet that is twice the size of earth, and it orbits a star similar to our sun. The main similarity is that it is rocky instead of a gas giant like all the other planets found so far.…

How great is named_scope?
If you haven’t used named_scope in Rails 2.1+ yet, I suggest you learn about it ASAP. Prior versions of Rails had a plugin that could perform similar functions, but it’s nice to have it part of the core system. What does it do? It does just what it says. It gives you a way to…
