If there's a better trials bicyclist in the world than Danny MacAskill, I've never heard of him (or her). The preceding video is simply the latest in a long series, every one of which will make you rethink what's possible for a bunch of metal tubes suspended between two rubber circles. I get sweaty palms just watching it.
Which prayer is Danny MacAskill using in his rooftops of Gran Canaria riding? Probably not the same one as mine. https://t.co/JJ7ysOWjOC-- Veerle Pieters (@vpieters) December 10, 2015
Two months ago, I couldn't spell "cartographer," and now I am [on my way to becoming] one. As a Geographic Information Systems (GIS) specialist, my duties include generating and editing maps, and I've found the learning curve to be challenging.
There are actually two different challenges. One involves learning the systems we use for mapping. Most of our engineering and geological analysis tools (for those in the know, we use Petra and GeoGraphix) include mapping modules, as do many of our online sources of production and industry activity data. Our company has a proprietary mapping application, and I'm also learning to use ArcGIS, one of the most powerful standalone GIS programs in existence. So, thus far I've used about six different programs, none of which I'd ever seen before August 22nd. Fortunately, they all employ similar conventions and processes, so the transition from one to another isn't that tricky. But like so many things in life, they're easy to learn and difficult to master.
The process of converting a three dimensional representation of the earth onto a two dimensional surface is called "projection," and humans have been experimenting with different kinds of projections for more than 2,000 years, trying to come up with the "best" way of locating geographical points of interest. The thing that all projections have in common is that they don't tell the truth...that is, none of them are completely accurate 3D-to-2D translations. They all distort one or more of the following characteristics: direction, distance, shape, or area. (For a nifty comparison of the more common map projections and their uses, advantages, and drawbacks, refer to this USGS resource.)
This is not just an academic or theoretical issue. The accuracy of maps has real and often significant implications. Maps can also be manipulated to achieve specific goals or serve specific agendas.
I'm reading a book entitled How to Lie With Maps by Mark Monmonier. I recommend it both as an easy-to-read reference for basic cartography, and as a primer on how maps are used to exert social, cultural, and/or political influence in ways that aren't necessarily ethical.
Anyway, while my specific job duties don't necessarily require that I understand some of the more esoteric cartographic principles, my natural curiosity about such things has led me to delve into a wide variety of resources, and if nothing else, I've learned how much I don't know. I've delved into the world of Great Circles, rhumb lines, sinusoidal projections, graticules, and azimuths.
That seems to be the story of my life. I keep telling myself that that's a good thing; it will keep my brain young. Someday, perhaps I'll even convince myself of that.
Tele Atlas supplies maps to the companies that make devices or applications, not directly to the people who use them. We update the map we supply so these companies can incorporate the map update in their own systems. When this process is complete, your change will be made available to you. It may be possible to purchase an updated map; please contact your device manufacturer or application provider for further information.
Thanks again for your willingness to help keep Tele Atlas maps up-to-date and accurate!
The December issue of MacWorld has a good tutorial for setting an "if found" message on the home screen of your iPhone. This is accomplished by creating an image to use as wallpaper on your iDevice, and that image is overlaid with text giving instructions regarding how to get in touch with the rightful owner of the lost device.
The example in the magazine uses the following text:
If found, please return phone to Dan Miller 415/555-5555
I'm not crazy about this example. For one thing, it's illogical; you can't return a phone to a name and a phone number. Also, I don't like the privacy implications of putting my name on my phone's screen, along with a phone number.
I think a better approach is what I've done, as shown below.
No name, no extraneous text, and the phone number I actually used in place of the sample shown above is my wife's mobile phone, making it harder to cross-reference to a person. But this also has the advantage of increasing the odds of the caller actually reaching someone quickly.
I think I'm more likely to misplace or drop my phone when I'm traveling, and most of my traveling nowadays is done with my wife. Using her cell number means that we wouldn't have to wait until we got home to get information about the missing phone. I'm simply playing the odds.
While MacWorld's tutorial is directed toward the iPhone, the technique will also work for iPad and iPod touch users. The iPod's screen resolution is the same as the iPhone's (320 x 480 pixels), but the iPad's is 768 x 1024 pixels.
Here are the steps for creating your custom "If Found" message.
The flight of the bats was filmed using an infrared camera which tracked their movements via their body heat. Amazing footage. I've watched it closely, and out of a half million bats (unaudited, I suspect, but still) I saw not a single collision. Drivers in Houston's rush hour traffic should be so skilled. (Via Wired)
