Of course, evolution is happening N-dimensionally, so going "downhill" in one aspect may be taking you "uphill" in another - which one wins depends upon selection pressure, luck etc.

And since selection pressures also happen in multiple dimensions (as well as being time and space varying - oh and non-linearities), the landscape of your objective function is constantly changing as well - so from one generation, "down" may become level or uphill, and genetic variation will also tend to scatter individuals through this N-dimensional hyperspace giving them slightly different starting points.

Enough for now? :-)

Submission + - Nissan turns to high-tech to stop drink driving

Submitted by StonyandCher on Friday August 03, 2007 @02:57AM

StonyandCher writes: As part of its drive to reduce road deaths and injuries, Nissan Motor has installed in a car three prototype high-tech systems designed to stop drink driving.

The first attempts to directly detect alcohol in the driver's sweat and gear shift lever. A second system in the car uses a camera mounted in front of the driver to monitor eye movement. If the driver is drowsy it triggers the seat belt to tighten and this movement will hopefully snap the driver out of their drowsiness or prompt them to take a rest. A third system monitors the path of the vehicle to ensure it's traveling in a straight line and not weaving about the road, as is common with a drunken driver.

An anonymous reader writes: Hendrik Hertzberg of The New Yorker reports that Californians vote next year on a radical change to the allotment of their state's electoral college votes. Republican sponsors call themselves Californians for Equal Representation, but if their measure passes, it's more likely than ever that a Republican will win the Presidency without winning the popular vote.

Your Wizard is level 16 and counting, Magicbane is at +2 and Mjollnir is at +7, and things are looking good. And then... Nethack crashes. Help!

I have poked around online, and I cannot find a Recover utility for Nethack 3.4.3 on Mac OS X. Any ideas? I have all the character files in the Nethack folder, so it may be recoverable. A cheap plastic imitation of the Amulet of Yendor for any useful links. Thanks!"

Coryoth writes: "The BBC is reporting that students in the UK are being encouraged to drop math at the senior levels. It seems that schools are seeking to boost their standing on league tables by encouraging students not to take "hard" subjects like mathematics, in favour of easier subjects in which they are assured good grades. The result is Universities being forced to provide remedial math classes for science students who haven't done math for two years. The BBC provides a comparison between Chinese and UK university entrance tests — a comparison that makes the UK look woefully behind. Is the UK slipping behind in science education?"

Does this yet have any 'real world' implications, or is it merely a scientific milestone to simply document & brag about?"
