Submission + - Ask Slashdot: What video games keep you from using Linux? 7

skade88 writes: Everyone knows content is king. Many of us use Windows or OSX at home instead of Linux because the games we love just are not available on Linux. With Steam moving forward for a Linux launch, I would like to hear from the Slashdot community on this topic. What are the game(s) you cannot live without? If they were available in Linux would you be happy to run Linux instead of Windows or OSX?

Submission + - Duke University creates perfect, centimeter-scale invisibility cloak (

MrSeb writes: "Scientists at Duke University have created the first invisibility cloak that perfectly hides centimeter-scale objects. While invisibility cloaks have been created before, they have all reflected some of the incident light, ruining the illusion. In this case, the incident light is perfectly channeled around the object, creating perfect invisibility. There are some caveats, of course. You didn’t really think you’d soon be sneaking away with Ron or Hermione (delete as applicable) into the woods, did you? For now, the Duke invisibility cloak only works with microwave radiation — and perhaps more importantly, the cloak is unidirectional (it only provides invisibility from one very specific direction). The big news here, though, is that it is even possible to create an invisibility cloak of any description. It is now just a matter of time before visible-light, omnidirectional invisibility cloaks are created."

I have a theory that it's impossible to prove anything, but I can't prove it.
