gollum123 writes with a link to the Berkley site about an impressive star explosion that took place some tens of millions of years ago. We first caught sight of it in 2004, when there was a bright outburst, ahead of a massive supernova. "All the observations suggest that the supernova's blast wave took only a few weeks to reach the shell of material ejected two years earlier, which did not have time to drift very far from the star. As the wave smashed into the ejecta, it heated the gas to millions of degrees, hot enough to emit copious X-rays. The Swift satellite saw the supernova continue to brighten in X-rays for 100 days, something that has never been seen before in a supernova. All supernovae previously observed in X-rays have started off bright and then quickly faded to invisibility."

Older models with the Dual-Core chips remain available. Base model with two 3.0 GHz Quad-Core Xeon processors start at $3997, (albeit with unacceptably minimal RAM or HD space; fully spec'd with dual 30" monitors and tons o' RAM/HD still over $10K... bummer)"

Brett writes "Results from energy companies are coming in, and the word is that moving Daylight Saving Time forward three weeks had no measurable impact on power consumption. The attempt by the US Congress to make it look like they were doing something about the energy crisis has been exposed as the waste it is. But the new DST is probably here to stay — letting the bill expire would mean re-patching a lot of systems again next year. So much for saving energy."

prostoalex writes "Music sales are not just falling, they're plummeting — by as much as 20% when you compare January-March 2007 with the 2006 numbers. The revenue numbers are actually worse, since CD prices are under pressure. The Wall Street Journal lists many factors contributing to the rapid decline: 800 fewer retail outlets (Tower Records' demise alone closed 89); increasingly negative attitude towards CD sales from big-box retailers (Best Buy now dedicates less floor space to CDs in favor of better-selling items); and file sharing, among others. Songs are being traded at a rate about 17 times the iTunes Store's recent rate of sales. Diminishing CD sales means that you don't have to sell as many to get on the charts. The 'Dreamgirls' movie soundtrack recently hit #1 by selling 60,000 CDs in a week, a number that wouldn't have made the top 30 in 2005."
