Clever folds in a globe give new perspectives on Earth - tech - 10 December 2009 - New ... - 0 views

    "Video: A new way to unfold the Earth's surface produces a new kind of map A new technique for unpeeling the Earth's skin and displaying it on a flat surface provides a fresh perspective on geography, making it possible to create maps that string out the continents for easy comparison, or lump together the world's oceans into one huge mass of water surrounded by coastlines. See a gallery of the new maps "Myriahedral projection" was developed by Jack van Wijk, a computer scientist at the Eindhoven University of Technology in the Netherlands. "The basic idea is surprisingly simple," says van Wijk. His algorithms divide the globe's surface into small polygons that are unfolded into a flat map, just as a cube can be unfolded into six squares. Cartographers have tried this trick before; van Wijk's innovation is to up the number of polygons from just a few to thousands. He has coined the word "myriahedral" to describe it, a combination of "myriad" with "polyhedron", the name for polygonal 3D shapes. Warping reality The mathematical impossibility of flattening the surface of a sphere has long troubled mapmakers. "Consider peeling an orange and trying to flatten it out," says van Wijk. "The surface has to distort or crack." Some solutions distort the size of the continents while roughly preserving their shape - the familiar Mercator projection, for instance, makes Europe and North America disproportionately large compared with Africa. Others, like the Peters projection, keep landmasses at the correct relative sizes, at the expense of warping their shapes. An ideal map would combine the best properties of both, but that is only possible by inserting gaps into the Earth's surface, resulting in a map with confusing interruptions. Van Wijk's method makes it possible to direct those cuts in a way that minimises such confusion. Maps of significance When generating a map he assigns a "weighting" to each edge on the polyhedron to signal its importance, influencing the pl

How Do You See America? - 1 views

  •  
    Let me start off by saying, the following maps are just JOKES. I'm a very proud American. But I will be the first to admit that my views of the rest of the world are a bit, well to be honest I have never been to any other country before (well Canada once, but that doesn't count.) Haha, C'mon, i'm kidding!! Anyway, don't take the following to seriously.

Technology Review: Mapping the Malicious Web - 1 views

  • Now a researcher at Websense, a security firm based in San Diego, has developed a way to monitor such malicious activity automatically. Speaking at the RSA Security Conference in San Francisco last week, Stephan Chenette, a principal security researcher at Websense, detailed an experimental system that crawls the Web, identifying the source of content embedded in Web pages and determining whether any code on a site is acting maliciously. Chenette's software, called FireShark, creates a map of interconnected websites and highlights potentially malicious content. Every day, the software maps the connections between nearly a million websites and the servers that provide content to those sites. "When you graph multiple sites, you can see their communities of content," Chenette says. While some of the content hubs that connect different communities could be legitimate--such as the servers that provide ads to many different sites--other sources of content could indicate that an attacker is serving up malicious code, he says. According to a study published by Websense, online attackers' use of legitimate sites to spread malicious software has increased 225 percent over the past year.

    Over the past couple of years, cybercriminals have increasingly focused on finding ways to inject malicious code into legitimate websites. Typically they've done this by embedding code in an editable part of a page and using this code to serve up harmful content from another part of the Web. But this activity can be difficult to spot because websites also increasingly pull in legitimate content, such as ads, videos, or snippets of code, from outside sites.

Not Cold Everywhere : CleanTechnica - 1 views

  • There’s a bit of news coverage right now about the cold weather that’s hitting certain parts of the world, but don’t jump into the idea that we’ve entered global cooling. Take a look at the rest of the world and a little historical perspective, as well as the reason why some of us are getting this cold weather in the first place.

Official Google Blog: Collaborative bookmarking with lists - 0 views

  • Today we’re debuting lists in Google Bookmarks, an experimental new feature that helps you easily share those sites with friends.Bookmarks are a great way to keep track of your favorite content across the web and we want to help you share them with your friends. To use lists, visit Google Bookmarks at google.com/bookmarks or by clicking “Manage all” in your Google Toolbar. From there, select the links you want to share and click “Copy to list.” Lists are private by default, but once you’ve created one you can share it with specific friends or even publish it to the web. For example, if a friend of yours is visiting Seattle for the first time and you have some local attractions bookmarked, you might want to create a new list for “Seattle attractions” and share it with your friend.
  • Google will algorithmically analyze your list to identify other potentially relevant links, such as the Seattle Aquarium. Similarly, when we detect that a list is relevant to a specific region, we provide a map of those places and relevant info for each place, such as addresses, hours and reviews.
