　VAIOやLet'snoteをネットブック以下の予算で買う！今週は中古パソコンが狙い目(参考：中古ノートPC )

　「5万円パソコン」として大ヒットしているネットブックに引っ張られるように、中古パソコンの値下がりが著しい。1～2年前の比較的新しい旧モデルでもネットブックと同等かそれ以下の価格帯で店頭に並ぶ。中にはネットブックより高性能なものもある。

■What Google’s Brin Said That Will Ruffle Wolfram Alpha’s Feathers　

　What Google’s Brin Said That Will Ruffle Wolfram Alpha’s Feathers

I think it will soon be possible to have a search engine that “understands” more of the queries and documents than we do today. Others claim to have accomplished this, and Google’s systems have more smarts behind the curtains than may be apparent from the outside, but the field as a whole is still shy of where I would have expected it to be.

1. Google has technology “behind the curtains” that it’s not yet ready to reveal, but likely more powerful than being touted by Wolfram Alpha.
2. Where Brin says “the field as a whole is still shy of where I would have expected it to be” you can translate that as him not being impressed by Wolfram Alpha’s offering.
3. “It will soon be possible” that we’ll have “a search engine” that understands our search queries better. He’s not talking about a different search engine folks, he’s talking about Google.

■OpenCL Library for Ruby "Barracuda"　

　Barracuda: An OpenCL Library for Ruby

Barracuda is my latest experiment. I wanted to toy around with the new features of Snow Leopard, and as far as I’ve seen, there are no CUDA or OpenCL wrapper libraries out there for Ruby.

You can install Barracuda if you’re on OSX 10.6 (Snow Leopard) or have a way to get OpenCL on your machine and hack up the Makefiles. I’d like to add support for other environments but I just finished this build.

If you have the right stuff you can grab it right from rubyforge:

sudo gem install barracuda

Or visit the git repo:
