    The funny thing about time traveling ...

    ... is that it will invalidate all patents as "prior art". But what you just need in this case is not pure time travel, but only the ability to send information back in time. Which brings the interesting question - assuming that there is a physical way...

    Building a bridge in France versus US

    • 13 Comments
    Recently I read an article about the newest bridge in Millau, France. Everything about this bridge is out of scale. The highest point is 1,125ft (343m). That's right - its pillars are taller than the Eiffel tower! And the highway is suspended at max 885ft...

    Who hogs down my CPU?

    • 6 Comments
    I always wanted to find a simple way to figure out the answer for this puzzling question. Usually I ended up opening Task Manager to find out what process eats all my CPU resources. But this doesn't work in most of the cases. For example, what about the...
