What if you could look down on people across the world without them knowing? Almost a god like view that often governments enjoy like in the movie "Enemy of the State" except without the hocus pocus of going through satellites and stuff. We explore this interesting world on this entry of the Programming Underground! Every day hundreds if not thousands of video cameras are installed around the world to track people ...
You may have heard of the idea of "Blackbox" development. Where is it? Can I open it? What does it contain? Is it that red rider BB gun I wanted from xmas all these years? NO!

Some of you may be old Google gadget pros. With a dozen or so of them on your fancy schmancy iGoogle page.

But what if you wanted to make something simple enough to get the basics, but more than a simple hello? Like so many other ...

The last thing you need hours before an assignment or project is due is to get that lame error that stops you dead in your tracks. You know it is going to happen, so why not just stop, take a ...
