Traffic-Flow Algorithm Can Reduce Fuel Consumption 328

thecarchik writes "New projects from German automakers Audi and BMW promise to ease congestion simply by looking at traffic signals and driving style, in an effort to smooth the flow of traffic. Through a test course in Munich, vehicles were able to post phenomenal fuel efficiency gains simply by adjusting the timing of traffic lights depending on traffic volume — to whatever speed provides a so-called 'green wave' of four or more synchronized signals."

The Virtual Choir Project 58

An anonymous reader writes "Conductor and composer Eric Whitacre has successfully created a virtual choir using the voices of 185 people who posted their performance on YouTube. The piece that's performed is called 'Sleep,' composed by the conductor himself in 2000. Anyone can join in — all you need is a webcam and a microphone."

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."

Silencing a Hard Drive Using Household Items 275

Reader Justblair recommends his blog entry detailing how he made a hard drive silencer for a pittance. "This article demonstrates a very easy-to-make hard drive silencer that not only outperforms most commercially available devices, but is cheaper to implement as well. Requiring very little in fabrication skills, it is an ideal addition to a media PC or HTPC. It may even suit you if your head is aching after many hours of being whined at by your hard drive."

Comment The meaning of faith (Score 1) 658

Well, that is a highly coloured definition of faith, and just one of the senses offered by Wiktionary.

It's late in the day to be adding to this discussion, but what I really wanted to get at is this: that though you may like that definition of the word, it's not the one your creationist friend has in mind when he says that it is "faith" that leads him to the conclusion that Darwinian evolution is wrong.

For what it's worth, I think creationists are mistaken in their conclusion that Christian belief is inconsistent with evolution. This must be due to a false premiss or faulty reasoning, but we must avoid in turn the worse error of supposing that all religious premisses are false or all religious reasoning faulty: that's absurd.

-- Mike

PS. I read some of the Origin a couple of years ago, and I must say I was bowled over by the richness of Darwin's perception of the ecological complexity of nature. It is beautifully subtle and yet completely accessible.
