Here’s a new Trail Baboon feature – three connected topics I’ve seen this week. I would say it’s akin to a primate swinging from tree branch to tree branch, but baboons are known for spending most of their time on the ground.

1.  It starts with a nice tidy explanation of how GPS works from Jeff Blossom, who makes maps for journalist Paul Salopek’s seven-year-long globe spanning project, the Out of Eden Walk. Thanks to a group of satellites and Blossom’s maps, we can clearly see exactly where Salopek spent some time standing around in Saudi Arabia. Yes, this technology can track your loitering habits. Even when on a ambitious mission, it sometimes becomes necessary to wait.

2. Those satellites are an essential component in guiding the autonomous cars we were discussing this week. I found a lovely Google video that drives home the point that such cars would be a delight for the disabled, kids, and old people.

3. But there is always a dark cloud on the horizon, threatening to blow your candy-colored dream to smithereens. Like an enormous power grid and technology-destroying electromagnetic pulse from the sun. People (including some at the Defense Department) are considering the ramifications of such a calamity, but none more ardently than Rocky Rawlins of The Survivor Library, who I heard in an interview with Bob Garfield on the program On The Media.

Rawlings is collecting knowledge about how to accomplish basic tasks and build and operate old-world devices that pre-date the digital age. Like how to make and felt a hat, for instance.

As a person with a hat-necessary type of head, I appreciate this attention to detail. But I’m a bit leery of the alarm-junkie quality that many survivalists bring to the task. There seems to be a bit too much of the “I Told You So” quality to their planning – as if this is all a wonderfully fun set up to a supreme moment when the rest of us dullards realize they were right all along.

What priceless skill could you contribute to a smoldering Hellscape of a non-digital world?
