Asian Inflation Begins to Sting U.S. Shoppers

From NYTimes.com: Asian Inflation Begins to Sting U.S. Shoppers

First, developing countries now produce nearly half of all American imports. Second, inflation in these countries is coming at the same time that many of their currencies are rising against the dollar.

That puts American consumers in a double bind, paying at least some of producers’ higher costs for making their goods, and higher prices on top of that because the dollar buys less in those countries.

It’s not clear what we can do about this inflation.  The Fed is pretty powerless to stop it since it’s based on global demand and rising wages around the world.  Normally, a week dollar would make U.S. goods more attractive, but what goods can we export besides commodities or services?  Most of the really innovative and new U.S. technology products are manufactured overseas now.

Thieves stealing catalytic converters

From NYTimes.com: Thieves Leave Cars, but Take Catalytic Converters

Theft of scrap metals like copper and aluminum has been common here and across the country for years, fueled by rising construction costs and the building boom in China. But now thieves have found an easy payday from the upper echelon of the periodic table. It seems there may not be an easier place to score some platinum than under the hood of a car.

The catalytic converter is made with trace amounts of platinum, palladium and rhodium, which speed chemical reactions and help clean emissions at very high temperatures. Selling stolen converters to scrap yards or recyclers, a thief can net a couple of hundred dollars apiece.

I had read this article a couple of weeks ago and was reminded of it by the same story on the Today show this morning.  It seems that SUV’s are a big target because they’re a little higher off the ground for easier access, plus the larger size of the catalytic converter means more precious metals.  If you see someone crawling under a car with a saw, call the cops!

Music from Battlestar Galactica

The music from Battlestar Galactica is one of the most underrated parts of the show.  Often moody and mysterious, the original compositions set the tone for the show.  There’s a song that isn’t an original song- Metamorphosis Five by Philip Glass.  It’s first played when Starbuck returns to her apartment on Caprica and puts in a tape of her father playing the piece.

Here’s a YouTube video of a live performance of this song being played.
