As well as the massive increase in speed, the researchers believe this is the first time room-scale has been achieved, with links operating over 60 degree and 30 degree fields-of-view (FOV) angles.The 224Gbit/sec speeds would, theoretically, allow you to download 18 1.5GB movies in a second. We say theoretically, because your hard drive wouldn’t be able to write fast enough to keep up – the fastest commercially available drive PC Pro has seen can write at 1GB/sec, so you’d need a data centre to handle 27GB/sec.While the researchers describe this as room scale LiFi coverage, the technology has one very important limitation – the device has to be in direct view of the signal-emitting lights.This means that, while devices could theoretically achieve connection speeds of 244Gbits/sec, you would need a specialised LED bulb in every room, as the signal can’t travel through solid objects, including walls. According to the LiFi Consortium, which seeks to promote the investigation and use of LiFi, this is an advantage in relation to security issues, but it also means that, for now, only desktop computers – or laptops that don’t get moved around – would be able to use LiFi.

Nevertheless, this is a huge breakthrough in the technology and, to a great extent, putting LEDs in all rooms and ensuring there’s full coverage of the room could mitigate this problem.Got a Lenovo computer? Heard about this “Superfish” thing that’s going around on the internet? Here’s a guide to help you remove that pesky digital haddock from intercepting your online communications.While we go into far more detail about it in our report, Superfish is adware installed on Lenovo computers, tracking what you do so it can push adverts at you while you browse.Good question, Superfish is dangerous because it’s a way for others to intercept your online communications and hijack your laptop, the perfect entryway into stealing your personal information.

Lenovo told PC Pro that it had removed Superfish from the preloads of new consumer systems in January 2015, and that while Superfish machines exist in the market, Superfish has completely disabled server side interactions (since January) on all Lenovo products.Lenovo has also stated that Superfish was never installed on ThinkPad notebooks, Lenovo desktops or its smartphones. Users who have enterprise products, such as servers or storage, are also not effected by Superfish.1. Check if Superfish is active on your computer: Head on over to Superfish CA test to check if you have Superfish active on your computer. If you do, it’s time to remove it! If you don’t, it may still be installed, but just not active – so do step 2 anyway.
2. See if Superfish is installed on your computer: Click the Start button and search for “Add or Remove Programs”, also called “programs and features” if you’re using Windows 10. Scroll down the list and see if you have “Superfish Inc VisualDiscovery” installed on your computer.
3. Uninstall Superfish: If you have Superfish Inc VisualDiscovery installed, right click and select “Uninstall”. Follow the on-screen prompts, entering an administrator password if prompted, and you’ll be free from the first part of Superfish’s gaze.
4. Search and remove old Superfish web certificates: Click the Start button and search for certmgr.msc and launch it – you may be prompted for an administrator password.
5. Locate Superfish Inc certificates: In Certmgr, click on “Trusted Root Certificates” and look for any certificates mentioning Superfish Inc. Remove them by right clicking and selecting “Delete”.
6. Restart all open browsers/restart computer: Make sure you close down all your browsers when complete, or restart your computer if you’d rather be extra safe, then just re-open them and you should be all clear of that nasty Superfish infection.
The HP Envy range of devices has traditionally been associated with high-end prices and luxury finishes, but recently the company has begun to widen the brand’s appeal. Nowadays, an Envy product needn’t cost the earth, as its £649 HP Envy 15 x360 ably demonstrates. It even comes with a year’s subscription to Microsoft Office 365 Personal.

Despite the reasonable price, though, this new Envy is a good-looking machine. It isn’t the slimmest or lightest laptop around – at 24mm thick and 2.4kg without the charger – but the smooth, metallic-coloured plastic it’s wrapped in looks smart. Open it up and the keyboard and touchpad are surrounded by an attractive, brushed-aluminium plate, with bevelled edges surrounding the touchpad that glisten and catch the light. It’s no MacBook Pro, but neither does it look cheap.Build quality is impressive: the keyboard base is unyielding, remaining immobile even when subjected to heavy-handed twisting, and the keys are well spaced and feel firm under the fingers. And there’s a reason for the x360’s bulk. It has a 360-degree hinge that allows the laptop to be used in a variety of positions, just like Lenovo’s Yoga convertibles.

The last two decades have seen a revolution in the way technology is used in the classroom. We’ve moved from a world where a handful of computers might have been found in a school’s computer lab to one where ICT suites and interactive whiteboards became a fixture of every school – and now to a world where fleets of laptops and tablets are used by many students throughout the school day.The pace of change has been extraordinary, but there are no signs that it’s slowing up. A new generation of devices allied with new software and services and shifts in pedagogy will only see further transformations on the shape of classroom tech. While ICT suites promoted the teaching of basic ICT skills in school, interactive whiteboards and laptops had an even bigger impact, transforming technology from a subject area to a tool that could help primary age students with literacy and numeracy, support history, geography and science lessons, or help young people get to grips with a world of digital media.

Combined with the internet, online resources and Virtual Learning Environments (VLEs), technology revolutionised education as a whole. Things have changed again since 2010, not just because of a change in government that has seen major changes to the ICT curriculum and the promotion of computing skills in schools, but because classroom technology is changing to reflect the devices and services being used in business and the home.The debut of Apple’s iPad was as much a watershed for schools as for the business and the home, as schools rushed to explore the clear potential of a simpler, more personal, highly versatile computer and a library of education-friendly apps.Behind the iPad has come a wave of Android and Windows tablets and convertibles, while Google’s Chromebooks have given schools a low-cost alternative to Windows laptops, hooked in to a world of cloud-based services, learning resources and free web-based apps.

Mobile technology has entered the classroom in style – and it’s shaking up the way we teach and learn.“I think that for certain, mobility is taking over” says Gus Schmedlen, HP Vice President of Worldwide Education, “especially in the mature or developed markets, where broadband availability and streaming availability are pretty pervasive.”For Schmedlen and HP, mobile devices play a critical role in preparing students for a world where every industry is being disrupted by technology, and where the most important skill a school can teach is learning itself.Backed up by cloud services and effective, easy-to-use management tools, they can make transform the way technology is used in the classroom, and help teachers improve outcomes in a tangible way.

HP’s latest mobile devices, including its Education Edition tablets and ProBook laptops, provide them with total access to learning, and can be better tailored to the way that individual students learn.For primary school students, this might mean working with a stylus to practice handwriting or basic maths skills. For secondary school students, HP’s partnership with Pasco turns its tablets into effective scientific instruments, where you can attach over 70 sensors to a tablet and see the incoming data live on the screen.The potential to engage students in exciting, practical science lessons should be clear.Economies of scale and cost reductions are also enabling more schools to look at 1:1 access schemes, where every student in specific years, or even across the whole school, is provisioned with their own tablet, Chromebook or laptop.This doesn’t just impact what and how students learn, but where. “1:1 is a reality now, when you look at the cost of these devices” says Steve Beswick, Director of Education, Microsoft UK. “You’ll get to a point where anytime, anywhere learning really can happen.”http://www.dearbattery.co.uk

For Beswick, though, it’s not just about having the devices, but about the way devices integrate with services and applications through the cloud.“It’s no point having 1:1 if it’s all disparate. You’ve got to handle it all in a seamless way. It has to be so that what Johnny does at home he can access from school, and what Johnny does at school he can access from home.”Beswick describes how, at Bett 2015, teachers using Windows mobile devices on the showfloor were able to use OneNote and Office 365 to set tasks for students back at school, then receive work and feedback from the classroom in real-time while still at the show.Both with Microsoft’s cloud services and Google’s flexible, integrated platforms are making for a dynamic and engaging environment for teaching.Liz Sproat, Head of Education, EMEA for Google, cites the take-up of Google Apps for Education and Google Classroom in UK schools, and how the new Google Play for Education initiative should drive more teachers to take advantage of mobile tech.

“We see more schools using this technology to improve learning” she says, “and really benefitting from the advantages it can bring. This is my second Bett at Google, and already the level of the conversation is getting much more involved.”Mobile technology also supports new blended approaches to learning. At Bett 2015, HP talked of Blended Reality, where students might use text books imprinted with a watermark that could trigger supporting video or audio materials on a tablet or smartphone.“If a student is trying to learn Pythagorean theorem and they’re confused about what it means, they can take their mobile device, put it over the Pythagorean theorem and see a video about it and why it works” Gus Schmedlen told us. “What we’re trying to do is increase the number of modalities that a student uses to learn one learning objective.”HP isn’t alone in this endeavour. Across the Bett 2015 showfloor we witnessed innovative approaches that combine digital content with real-world materials to engage students and improve learning.
