David Pogue's 10 Timesaving Tech Tips

10 Tech tips from David Pogue, who is a savvy columnist and author for the New York Times (and who, several years ago, showed me Zattoo - if you're in Switzerland, and not familiar with that site, go look). Pogues' blog is a good one to subscribe to for tech ideas, hints, opinions, outlook, etc.

Tech columnist David Pogue shares 10 simple, clever tips for computer, web, smartphone and camera users. And yes, you may know a few of these already -- but there's probably at least one you don't.

A few of these 10 tips are only work inside the USA, but most are general "good things to know" for any computer user.

Speculative Sea Level Explorer

Global Warming, sea levels rising...what would that look like?  A post this morning on the Information Aesthetics blog can help us see the possibilities.
"While the simulation, captured as a series of animations, is roughly accurate, it actually shows the consequence of more "dramatic" changes in sea level than what is currently expected by climate change models." (link)
And dramatic it is!  Here is the simulation for Zurich.  Here is the Legend (meters above sea level) to help you understand what you see in the simulation.

Click through to Gross' web page to see other videos for other areas of the world.  He writes about the simulation on his page:
"When I showed the animations to others, I was asked quite a few times whether this simulation is accurate? Short answer is “yes” in a rough way, especially for the large scale changes like the ones I am showing in the animations. The simulation is based on an elevation data set called “SRTM30 Plus” by the Scripps Institution Of Oceanography, which is an extended version of the original NASA Shuttle Radar Topography Mission(often abbreviated SRTM, land elevation only) enhanced with bathymetry (underwater evaluation). But there are also many limitations e.g. the cost region of the Netherlands is obviously wrong (it is on a rise of “+0″ already coloured blue). Altogether it is just a very basic and rough simulation based on the raw elevation, anything else in not put into consideration." (link)

We know that the sea level has risen and fallen though geological time.  That's why we can see sea-creature fossils at the top of Swiss mountains.   If you want more background information, visit the British Geological Survey web site.
