  • Off the commercial off the shelf “smart” TVs available, I started by looking at the OSes available. Choices were Roku, webOS, Tizen, and Google TV. I immediately ruled out Roku because of their recent changes to terms&conditions. webOS is pretty much limited to LG TVs, and I had bad experiences with LG warranties, so I ruled that out. Tizen (Samsung) was out for similar reasons, so that left me with Google TV. It’s… OK. Doesn’t require Internet connection to work, and doesn’t nag me about it. And it came with a hardware switch to turn off the microphone. Not sure if that’s a brand thing (Hisense) or applicable to all Google TV devices, but was reassuring.








  • Not a stupid question at all. Here’s the Wikipedia article for it. The significant part is this:

    The 5-dimensional discs [have] tiny patterns printed on 3 layers within the discs. Depending on the angle they are viewed from, these patterns can look completely different. This may sound like science fiction, but it’s basically a really fancy optical illusion. In this case, the 5 dimensions inside of the discs are the size and orientation in relation to the 3-dimensional position of the nanostructures. The concept of being 5-dimensional means that one disc has several different images depending on the angle that one views it from, and the magnification of the microscope used to view it. Basically, each disc has multiple layers of micro and macro level images.
