The way we navigate in cities has been revolutionized in the last few years by the advent of GPS mapping programs. Enter your start and end location and these will give you the shortest route from A to B. That's usually the best bet when driving, but walking is a different matter. Often, pedestrians want the quietest route or the most beautiful but if they turn to a mapping application, they'll get little help. That could change now thanks to the work of Daniele Quercia at Yahoo Labs in Barcelona, Spain, and a couple of pals. These guys have worked out how to measure the "beauty" of specific locations within cities and then designed an algorithm that automatically chooses a route between two locations in a way that maximizes the beauty along it. "The goal of this work is to automatically suggest routes that are not only short but also emotionally pleasant," they say. Quercia and co begin by creating a database of images of various parts of the center of London taken from Google Street View and Geograph, both of which have reasonably consistent standards of images. They then crowdsourced opinions about the beauty of each location using a website called UrbanGems.org. Each visitor to UrbanGems sees two photographs and chooses the one which shows the more beautiful location. That gives the team a crowdsourced opinion about the beauty of each location. They then plot each of these locations and their beauty score on a map which they use to provide directions. The idea here is that the user enters a start and end location and an algorithm then finds the most beautiful route, rather than the shortest one. It does this by searching through every possible route, adding the beauty scores for each and choosing the one that ranks highest.

Protecting yourself against harmful and life threatening viruses, its best to choose the antivirus by brand name. But each Antivirus download that you can find on the internet is dependent on what is most important to the user in terms of variables. Some are more dedicated to filtering through malware and spyware; some systems pride themselves on being the most reliable, or adaptable to the constant change of cyberspace gunk that's floating around. So with all these choices, how're we supposed to know which program is suited to our professional needs? We hope to address those concerns and point the potential onlooker in the right direction for a potential download, or perhaps full-on purchase of the bundled software. For the moment we'll be looking at Avast! and AVG which are both free antivirus downloads available for your computer on reliable online websites. Avast! Free Antivirus Software: The Basics Chances are if you're looking to get in on the ground floor to check if Avast! is right for you, then you'll be looking into the coverage that the free antivirus download is going to offer. Avast! is ranked as one of the top antivirus programs in the market with 17% of users in the entire market share of protection services. Which is pretty far up there with McAfee, Bitdefender, and other potential competition. AVG Antivirus Software: The Basics In comparison to Avast! the folks at AVG are a little behind in their numbers at 170 million+ having entrusted their computer's health to the program. But the software itself is secure and accessible on their website. AVG have won an array of awards for their antivirus software, and can be considered a lively competitor to Avast! and other protection bundles.

Always Online The Anqor itself is fairly straightforward, as a device. It's about the size of a novelty paperback you get as a gift, and relatively light, although that's just the prototype; the end goal device is roughly the size of an iPhone. And it works relatively simply, as well; it connects to a 3G or 4G network in the area you're in, connects to up to ten of the devices you have handy, and we're off to the races. It's how it connects that's more interesting. SIMulated Card As we all know, to access a local mobile network, you need a SIM card, which is profoundly annoying. What the Anqor does is determine where you are, riffle through the company's library of SIM cards, upload the profile, and you're done. The tradeoff, of course, is that this doesn't come cheap. Global travelers looking for this convenience will be paying roughly $52 a month for the library, although you can pause a subscription at any time, and for just one country, it'll be a more reasonable $16 a month. Online Anywhere If you're a world traveler, you know from experience that you'll be running around juggling SIM cards anyway, so you may as well clean some of the clutter out of your life. And, if you never leave the country but your job requires constant Internet access, this might be worth it as well. The device, without data plan, will start at around $270 if you get in early on the Kickstarter.
