GPS Down: Lost is Space. Time. And Money

Developed by the military, GPS is everywhere. We depend on it for military, civilian and commercial tracking of cargo ships, cars, trains, orbiting satellites of all stripes, and items easily geo-tagged with a trackable chip.A moving lattice of 31 GPS satellites orbit the earth at about 12.000 miles such that at any one time, something like Google Maps can read your position by 6 or more satellites to triangulate your position, speed and direction of travel. Unless...What was vastly complex, expensive and rare--jamming or spoofing GPS signals--today is simple, cheap and common. And increasingly dangerous to a world become dependent … Continue Reading ››

It might be trivial. It might produce only an itchy spot or  symptoms that are brief and go away entirely.

Hitched to Everything Else

My point was to say, at the beginning of something I thought I was going to write about this morning that, when I sit down to write about the importance of x, I find I can’t go on until I explore its relationship to a-through-zed.It’s nigh impossible to tease any single fact or observation apart from its context in time and space, its place along the continuum in the history of human knowledge. There are no lone truths.Any given bit of data, then, as I try to focus, becomes the object of another track of discovery. And that,  of yet another … Continue Reading ››
