Sharing files with colleagues and clients should be easy and convenient. What it shouldn't be is a security risk - but it frequently is. Because many small businesses don't have the right file-sharing systems and policies, many turn to unsafe practices that often put both their business's and clients' privacy in jeopardy. Is your business guilty of engaging in dangerous file sharing habits? Here are five you need to watch out for and what you can do about them. 1. Sharing files via email The most obvious dangerous habit is sharing files via email. Just the other day I received a design document from a client as an email attachment. 2. Using consumer-grade cloud solutions Workers around the world are putting themselves and their employers at risk by indiscriminately using unauthorized file sharing services on their mobile and desktop devices - to the tune of $2 billion. With more workers joining the bring-your-own-device (BYOD) revolution and turning to insecure file sharing services like personal Dropbox and Google Drive accounts, the threat is greater than ever. 3. Peer-to-peer (P2P) file sharing P2P sharing is a great technology used to share data over peer networks. It's also great software to get hacked. 4. Using flash drives Flash drives are the easy tool of choice for infection since they bypass network security. If an infected file is on a flash drive and inserted into a system, it can start an infection spread from the PC. 5. Lack of visibility The danger starts when employees take matters into their own hands and engage a file sharing service on their own. The individual making a one-off decision is not going to be thinking of the bigger picture of organization-wide requirements.

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.

Mastercard warns: invest or face economic consequences. Many UK businesses are struggling to expand and develop to their full potential due to a lack of proper investment into new technologies such as alternative payment methods, a senior Mastercard executive has told CBR. Marcia Clay, the groups' UK and Ireland head of strategy and commercial development, explained that UK consumers are increasingly calling for innovative technologies such as mobile payments as they look to simplify their everyday lives. "I believe we need to prioritise support for innovative start-ups, businesses in the eCommerce and mobile payments sector for example, which are in a unique position to propel the UK economy forward in 2014 and beyond," she said. Clay detailed how Mastercard is working with London-based Startupbootcamp FinTech, providing the expertise, mentoring and access to a network of industry professionals that most early-stage FinTech start-ups would not be able to access otherwise. Mastercard has found that many small businesses still do not use electronic payments, despite almost 80% of UK businesses having a website or some sort of online presence. A much smaller percentage can currently accept card payments, and the company believes that businesses of all sizes should be encouraged to invest in new technology and services that give consumers more choice. The company also found that UK consumers are using mobile and contactless payment methods and wide-spread adoption is reaching a critical mass; with around 5.7m transactions taking place on UK smartphones every day. This has been spurred on by a major growth in contactless payments, which grew by 383% from 2012 to 2013 across the country a

Android, iOS, Windows Phone. Each of these mobile platforms had to start somewhere, and none were anywhere near perfect on the first try. Fortunately, each OS gets better with every iteration until, at some point, it all just clicks. Arguably, Windows Phone just came of age with its latest update, version 8.1. Even before today, Windows Phone only had a few big holes remaining and indeed, 8.1 appears to fill those gaps. In particular, the OS now has a fancy notification center in addition to those signature Live Tiles; the keyboard now allows for swipe gestures; and last but not least, it now has Cortana, a virtual assistant to take on Siri, Google Now and Samsung S Voice. The 8.1 update is a fairly significant one, and I got the opportunity to take it for a spin ahead of the official developer preview's launch. It may not be perfect yet, but it's clear Windows Phone has finally grown up. Cortana Windows Phone included a search option from the beginning, and though it was useful at the time, rivals like Siri, S Voice and Google Now have quickly turned the tide, rendering Microsoft first "voice assistant" completely obsolete. Thankfully, the 8.1 update introduces a personal assistant named Cortana to help bring Windows Phone into the modern era. Named after Master Chiefs trusty AI sidekick in Halo, Cortana is designed to help you do whatever you do on a phone. Think: scheduling appointments, alerting you to upcoming flights, telling you the weather, offering up directions, dictating messages, opening apps and adjusting settings. She even tells jokes and responds in humorous ways to (most) silly questions. Those are all givens these days, so let's instead move on to the more unusual things she can do.

On April 16, IT sector lawmaker Charles Mok was the mover of a joint statement backing the setting up of an innovation and technology bureau and urging fellow legislators not to mount a filibuster during the debate on this issue. A filibuster is characterised as a form of obstruction in a legislature. It is a strategy employed by minority representatives to give them some leverage in defence of their constituents' interests. Executed shrewdly, it can be a David and Goliath tactic that can be successful. Hong Kong has been criticised for lagging behind its rivals in cultivating a new sustainable economy. The performance of its economy over the last decade has been unimpressive. In real terms, average personal incomes have seen little or no growth, meaning Hongkongers' lives have not improved. Also, Hong Kong's increasing economic reliance on mainland China is a cause for concern. If the SAR's free economy is homogenised with the mainland's towering planned macroeconomics, there could be unforeseen and dangerous consequences. Tech Reviews by The Corliss Group

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.
