Genetic Glitch May Prevent Kids From Learning From Their Mistakes 500

jamie pointed out an interesting piece being featured in Newsweek that claims a "genetic glitch" may prevent some kids from learning from their mistakes to the same degree as others. "If there is one thing experts on child development agree on, it is that kids learn best when they are allowed to make mistakes and feel the consequences. So Mom and Dad hold back as their toddler tries again and again to cram a round peg into a square hole. [...] But not, it seems, all kids. In about 30 percent, the coils of their DNA carry a glitch, one that leaves their brains with few dopamine receptors, molecules that act as docking ports for one of the neurochemicals that carry our thoughts and emotions. A paucity of dopamine receptors is linked to an inability to avoid self-destructive behavior such as illicit drug use. But the effects spill beyond such extremes. Children with the genetic variant are unable to learn from mistakes. No matter how many tests they blow by partying the night before, the lesson just doesn't sink in."

Is Gentoo in crisis? 199

TheCoop1984 writes "A recent article on distrowatch, and an extended thread on the gentoo forums, have pointed out that gentoo is not what it used to be. Daniel Robbins came back and went again after only a few days, developer turnover is as high as ever, personal attacks on the mailing lists are common, and people are generally not happy about the current state of affairs. Is gentoo rotting from the inside, and can anything be done about it?"

Is Daylight Saving Shift Really Worth It? 652

Krishna Dagli writes "Two Ph.D. students at the University of California at Berkeley say that Daylight Saving Shift will not do any good or create any energy savings. We are already spending money for software upgrades in the name of saving energy and after reading following article I wonder has congress really studied the impact of DST shift? " I also read some back story on the concept; OTOH, I found TiVo's suggestions that I manually change everything on my Series 1 device to be somewhat...insulting.

French Parliament Chooses Ubuntu 174

atamyrat reminds us that last November it was announced that the French Parliament had decided to switch to Linux. At that time the distro had not been determined. It will be Ubuntu: "[T]wo companies, Linagora and Unilog, have been selected to provide the members of the Parliament as well as their assistants new computers containing free software. This will amount to 1,154 new computers running Ubuntu prior to the start of the next session which occurs in June 2007."

Submission + - Drug selectively removes rats memory

rednuhter writes: Nature online is reporting scientists have used drugs to selectively remove one memory while unaffecting another. Musical tones were played to the rats and at the same time the subjects were given a mild electric shock. Half the study group were given the drug (not approved for use in humans) and then the experiment was repeated with a new tone. The following day the rats that had not been given the treatment were afraid of both tones while the treated half were only afraid of the second tone, the memory of fear of the first had been erased.

Submission + - Defense Contractor Halliburton Moving HQ to Dubai

theodp writes: "Much-maligned defense contractor Halliburton is moving its corporate headquarters from Houston to Dubai in the United Arab Emirates. Dubai's friendly tax laws will add to Halliburton's bottom line. Last year, it earned $2.3B in profits. Sen. Patrick Leahy called the company's move 'corporate greed at its worst.' Halliburton, once headed by VP Dick Cheney, has received contracts valued at an estimated $25.7B for its work in Iraq."

Opera's Slashdot Easter Egg and Speed Dial 157

Thelomen writes "Opera Browser contains an Easter egg that is not widely known, recently reported over at OperaWatch.com: type /. in the address bar and you are taken directly to slashdot.org. Other recent news from Opera is their new Speed Dial feature, present in the most recent build from Desktop Team. At first glance Speed Dial just looks like 9 bookmarks you can open with CTRL+1 to CTRL+9. However, the pages on the Speed Dial are shown in thumbnail and are automatically pre-fetched in background — a useful thing if you have some heavy pages among your top bookmarks."

Googlebot and Document.Write 180

With JavaScript/AJAX being used to place dynamic content in pages, I was wondering how Google indexed web page content that was placed in a page using the JavaScript "document.write" method. I created a page with six unique words in it. Two were in the plain HTML; two were in a script within the page document; and two were in a script that was externally sourced from a different server. The page appeared in the Google index late last night and I just wrote up the results.

Why Dell Won't Offer Linux On Its PCs 628

derrida sends us to an article in the Guardian by Jack Schofield explaining why he believes Dell won't offer Linux on its PCs. In the end he suggests that those lobbying Dell for such a solution go out and put together a company and offer one themselves. Quoting: "The most obvious [problem] is deciding which version of Linux to offer. There are more than 100 distros, and everybody seems to want a different one — or the same one with a different desktop, or whatever. It costs Dell a small fortune to offer an operating system... so the lack of a standard is a real killer. The less obvious problem is the very high cost of Linux support, especially when selling cheap PCs to naive users who don't RTFM... and wouldn't understand a Linux manual if they tried. And there's so much of it! Saying 'Linux is just a kernel, so that's all we support' isn't going to work, but where in the great sprawling heap of GNU/Linux code do you draw the line?"
