FourSquare Tips containing Adverts #gps #geolocation #jobs

leave a comment »

I recently started noticing that certain locations that I check into had tips which were usually for companies close to that location. An example it the ING Bank advertising their career site when you are in the discount electronics shop across the road or in the mall. Or Heineken informing you that you can link your FourSquare profile to your Heineken profile.

GPS Wiretapping Lawsuit

with one comment

On BetaNews I just saw that:

“The American Civil Liberties Union and Electronic Frontier Foundation are suing the Justice Dept. for “documents, memos, and guides” about procedures used to track individuals through cell phones.

“The [ACLU] and the [EFF] aren’t looking for money … Instead, the two civil liberty advocacy groups want information about whether and how the government might be using the location capabilities in cell phones to find out where people are.”1

The 9th Circuit Court of Appeals had already upheld the ruling that the FBI was not allow to spy on in-car computers, which was made possible by the system, “… a 2003 lawsuit revealed that systems such as OnStar can be used for eavesdropping on passenger conversations”

  1. US Justice Dept. sued for info on cellular tracking practices
  2. Court to FBI: No spying on in-car computers
  3. FBI taps cell phone mic as eavesdropping tool

Shortest or Fastest Route for saving the World

with 2 comments

I saw 8 Geeky Ways to Save Gas and at the section “Use GPS or mapping tools” I read this:

“It may sound obvious, but think of how much gas you waste driving around when you’re lost or trying to find a parking garage. Map out your route in advance to devise the shortest route (rather than the fastest one), which can also put you on secondary roads where you’ll drive more slowly—another gas-saving benefit. Some GPS units also let you program them to pick routes that avoid toll roads, where you can burn gas idling in line.”(emphasis mine)

It doesn’t sound that obvious that taking the shortest route is more efficient than the fastest route. Apparently somebody else thinks the same with their patent “Method and system for calculating least-cost routes based on historical fuel efficiency, street mapping and location based services“:

“The system will determine the best of all calculated routes based on the vehicles estimated MPG, historical data and efficiency in traversing various terrains. In one example, a vehicle towing a heavy trailer would consume fewer MPG if it took a longer but more flat route while the same vehicle without the extra weight would achieve better MPG by going a shorter route over more hilly terrain. This method would produce the best MPG rating for a given trip. With this new system in place, the driver will be able to query a mapping software program product that is based on optimal gas mileage rather than on speed or distance alone.”

In fact even the article Sat-nav finds greenest routes in the that “… taking more eco-friendly routes cut[s] motorists’ average fuel usage by 8.2%.

“The most efficient roads are often those where you can drive at a fairly slow, constant speed, without having to stop or suddenly accelerate or decelerate,” Dr Ericsson told New Scientist magazine.
