Step counting apps might be not only a waste of time but a dangerous one, according to one expert. The fitness apps might be doing more harm than good because they don't work but force people to focus on ambitious goals that they will never reach, according to a leading computer scientist. "Very few" of the roughly 165,000 healthcare apps are actually based on any scientific evidence, said Dr Greg Hager, from Johns Hopkins University in the US. But they have been downloaded more than a billion times by people looking to improve their health.

A new tool shows just how much of people's personal information is made public on Facebook for anyone to see. The utility, which calls itself Stalkscan, claims to offer all the "'public' info Facebook doesn't let you see". It combs through everything that has been made public by a person – which will probably have happened involuntarily – and collects all of it in one place. It does that using only the unique identifier that each profile has. That means that it's possible to do it for yourself, and see what parts of your online life you may have left exposed, but also that anyone in the world can do it to you, too.

In the immortal words of Steve Jobs: "A lot of times, people don't know what they want until you show it to them." You might believe that customers will love your movie, your product, your job opening- but they may not even know it exists. The job of a Recommendation Engine is to open the customer/user up to a whole new world of products and possibilities, which they would not even think of directly searching for themselves. A Recommendation Engine plays a vital role in increasing the chances of a user buying a product. In today's world, with tons of data from searched products available (thanks to the digital data explosion), it is very easy to find what people are likely to buy – just by looking at their'intent' data. Needless to say, right analysis of such BIG data is absolutely necessary.

How many people could self-driving cars kill before we would no longer tolerate them? This once-hypothetical question is now taking on greater urgency, particularly among policymakers in Washington. The promise of autonomous vehicles is that they will make our roads safer and more efficient, but no technology is without its shortcomings and unintended consequences -- in this instance, potentially fatal consequences. "What if we can build a car that's 10 times as safe, which means 3,500 people die on the roads each year. Would we accept that?" asks John Hanson, a spokesman for the Toyota Research Institute, which is developing the automaker's self-driving technology.

Amazon Lex is the tech that powers Alexa, which is used in the Amazon Echo (above) and Fire TV. With the rise of personal assistant chatbots, the tools required for organizations to build their own assistants are being moved to the cloud to give developers the ability to leverage these technologies in their products. Foremost among these tools is Amazon Lex, the speech recognition and natural language processing technology that powers the Alexa virtual assistant, used in the Amazon Echo speaker and Fire TV digital media player. TechRepublic's smart person's guide to Amazon Lex is an introduction to the language processing technology. This "living" guide will be updated periodically as further integrations are released.

The digital revolution is faster and more comprehensive than the Industrial Revolution at the beginning of the last century. It requires less capital, and focuses on intellectual and digital innovation, which is affordable to many. The innovations produced have therefore had a much more immediate impact on the market. A wide variety of services are now offered by the leaders of this digital revolution, including Google, Amazon, Facebook and Apple. This has resulted in a rush to set up data-oriented cultures and predictive algorithms, to increase company knowledge and automate more business processes.

IT professionals today have more demands (and more acronyms) on their time than ever. Application development and delivery are changing rapidly and increasing in complexity, revealing the limitations of traditional DNS approaches in achieving modern network goals. The IT department has made use of open source platforms for decades to provide DNS and traffic management in their internal networks and for their public, internet-facing services. The majority of DNS servers, both on the internet and in enterprise intranets, are open source-based solutions such as BIND, djbdns, PowerDNS, gdnsd and NSD. It can feel like shoving a square peg into a round hole to try to adapt these solutions to perform the functions needed in today's environments.

Imagine a world where nurses and doctors use remote monitoring solutions not only to analyze a patient's vitals such as blood pressure, weight and heart-rate, but also to interpret a patient's mood based on speech and tone analysis during a scheduled phone conversation,

SAM Seamless Network protects network equipment at the application level. For example, its software will enable ISPs to protect home routers by providing a security hub for devices in the home.

Google has launched its Fact Check tag in three more countries, as it steps up its efforts to combat fake news. The label will now appear in the expand story box in Google News search results and the Google News and Weather app in Argentina, Brazil and Mexico. The feature first launched in the US last October, ahead of the Presidential election, and has since been rolled out in France and Germany.
