A couple of days ago we discussed a CNet article on the tech voting record of Joe Biden, Barack Obama's running mate. Philip Zimmermann, who was mentioned in that piece, sends the following note to set the record straight. "In his 23 August opinion piece in CNet, Declan McCullagh wrote on Joe Biden's suitability as the Democratic VP nominee, Declan quotes me, creating the impression I criticized Biden for some legislation that Biden introduced in 1991. Declan's quote from me is out of context because it does not make it clear that I never mentioned Biden in my original quote at all when I wrote about Senate Bill 266. Second, Declan's quote is drawn from remarks I wrote in 1999. Declan seems to be trying to draft me in his opposition to Biden, and, by extension, makes it seem as if I am against the Democratic ticket. I take issue with this." Read below for the rest of Phil's comments.

Roland Piquepaille writes "Researchers at the University of Rochester have found a way to change the properties of almost any metal by using a femtosecond laser pulse. This ultra-intense laser blast creates true 'black metal' from copper, gold or zinc by forming nanostructures at the surface of the metal. As these nanostructures capture radiation, the metals turn black. And as the process needs surprisingly low power, it could soon be used for a variety of applications, such as stealth planes, black jewels or car paintings. But read more for additional references and a picture of this femtosecond laser system."
