It's a truth as universal as it is annoying; if you want all your devices to work with a specific keyboard, well, you'll probably need either one for each, sign on for precisely one device ecosystem, or get used to swiping in words. Travelers in particular are driven insane by this problem, so Logitech decided, quite cleverly, to solve it with the K480. Swiss Army Keyboard There are two problems with modern portable keyboards. The first is, as we noted, device compatibility. Ask anybody who's had to install drivers just to get a basic keyboard to work, the various device ecosystems out there don't play well with each other and seemingly want to drive you insane. Logitech solves this with some clever design. You can switch between three different places to send your words, so that regardless of whether you're all Apple, or a mix of Apple, Chrome, and Windows, you'll be able to use the keyboard and get the point across. Basically, if it uses Bluetooth, you're all set to type. At The Trough The second problem is keeping all your stuff organized; you've got your phone over here, your tablet over there, and your laptop in front of you… and many keyboards want to be docked solely at your tablet. How does Logitech solve this? Simple: It puts a trough at the top of the keyboard that can easily be used to stand up both your tablet and your phone, and to type away at both of them with ease. A Keyboard For The Multitasker Multitasking, or at least sorting through your various tasks properly, can be a profoundly annoying experience, and Logitech deserves credit for looking at how we actually use our gadgets and creating a keyboard that fits in with them. If that's something you need, it starts at just $50.

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.

http://www.technologyreview.com/news/523846/how-a-database-of-the-worlds-knowledge-shapes-googles-future/ Compiling a giant database of all the facts in the world could help Google's future products understand you better. For all its success, Google's famous Page Rank algorithm has never understood a word of the billions of Web pages it has directed people to over the years. That's why in 2010 Google acquired Metaweb, a company building a database intended to give computers the ability to understand the world. Two years later the company's technology resurfaced as the Knowledge Graph (see "Corliss Tech Review Group: http://thecorlissreviewgroup.com/"). John Giannandrea, vice president of engineering at Google and a Metaweb cofounder, says that will lead to Google's future products being able to truly understand the people who use them and the things they care about. He told MIT Technology Review's Tom Simonite how a data store designed to link together all the knowledge on Earth might do that. What is the Knowledge Graph? It's a distillation of what Google knows about the world. An analogy I often use is maps. For a maps product you have to build a database of the real world and know there are things called streets, rivers, and countries in the physical world. That's creating a symbolic structure for the physical world; the Knowledge Graph does that for the world of ideas and common sense. We have entities in the knowledge graph for foods, recipes, products, ideas in philosophy or history, and famous people. We can have relationships between them, so we can say these two people are married or this place is in this country or we can say this movie is related to this person. How does that make a difference to Google's Web search? We've gone up a level from just talking about the words to talking about what the thing actually is. In crawling and indexing documents we can now have an understanding of what the document is about. If the docum
