Comment Re:How does this differ from John Holland's work ? (Score 1) 85

It's worth reading the paper: http://www.pnas.org/content/ea...

The point is that the well known properties of the game theory algorithm explain why sex has the effective properties which have been observed but not explained. I haven't read John Holland's paper. Does it refer to the details of the multiplicative weight updates algorithm?

Comment Ideograms (Score 1) 420

I think the same approach to reading makes reading ideogram based languages, such as Chinese and Japanese written using Kanji, particularly efficient. My (not scientifically tested) impression is that reading a simple sentence in Japanese is faster than in English (I'm a native English reader and no expert in Japanese).I guess reading Egyptian Hieroglyphs was similarly fast.

The State of Ruby VMs — Ruby Renaissance 89

igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."
