When does justified concern become paranoia? It’s a tough question to answer in the internet age because there are so many different ways you can be attacked. For example, you’re not being paranoid if you think you’ll be targeted by email scams. If you’ve never had one, you must’ve spent the past 25 years living in the Mariana Trench (internet connection there is terrible, I’ve heard). But neither are you paranoid for worrying that hackers might be intercepting and reading your emails. It’s not as constant a threat as scams, but imagine the damage a malevolent fraudster could do if they knew what you’ve said in emails to your loved ones, bank manager, doctor or solicitor. Using end-to-end encryption is the safest way to protect your messages. We start our…

Motorists won’t be able to touch their phones while driving for any reason under a law the Government hopes to pass early next year, following a consultation. It would close a loophole that currently allows drivers to take photos, scroll through music playlists or play games on handheld devices. This loophole exists because these acts aren’t legally considered as “interactive communication”, which is the definition that bans making calls or sending texts. Ministers say exemptions will be made to let drivers pay for items using contactless payments if a vehicle is stationary and the goods are delivered immediately, such as at a drive-through takeaway. However, the Government has rejected calls to ban drivers using hands-free phones to phone people on loudspeaker or operate a sat-nav placed in a cradle. Roads…

You’ll soon be able to check online whether escalators and lifts are out of order at train stations after Network Rail released technical data to software developers. Network Rail hopes software companies will use this info to build apps and websites that show in real time whether an escalator or lift is working. It means you’ll be able to plan your journey better before leaving or while on route. The data comes from devices built into escalators and lifts that monitor whether they’re working. Network Rail will initially release this information for around 370 stations nationwide, building up to the full 463 stations over the next 12 to 18 months. There are 1,500 lifts and 300 escalators in the UK’s train stations. Network Rail will also make the information available…

Jury’s verdict: it’s a scam I received a text message telling me I’d been summoned for jury service, but could pay £34.99 to postpone it for six months. For a brief second I was caught unawares, thinking it was real. I’m more used to Amazon and HMRC scams, and had never received anything like this before. But then it quickly dawned on me that it was a con, which was confirmed when Trading Standards reported it (www.snipca.com/36295). As they say, the message looks real, and has an email address with ‘gov.uk’ in it. They also say that you’ll never have to pay to postpone jury service. Eric Bennett Warn your fellow readers about scams at letters@computeractive.co.uk…

Currys has stuck to its guns in Ernest Dempsey’s case to get a refund for the £45 it charged him to fix his computer. As we explained in Issue 588, Currys said the problem with his PC was an “operating fault”, and therefore not covered by its warranty. It told Ernest he would have to pay for a repair. We asked Currys what it meant by “operating fault”. It claimed Ernest had caused the problem by trying to transfer a cloned Windows 7 hard drive to the new computer, and therefore it wasn’t an inherent fault covered by the warranty. Ernest told us that he did try to clone his drive, but isn’t sure whether this caused the problems. It’s possible this was to blame, but we’d know only by inspecting…

IMAGE EDITOR ImBatch 7 www.snipca.com/36370 What you need: Windows 7, 8.1 or 10 ImBatch lets you queue up multiple images, then apply a range of effects (or ‘tasks’) – including cropping, resizing and rotating – to all of them. This version is the first one available as a 64bit tool and its developer says adding images to the input queue is now much faster. We put this to the test by applying three effects to 42 images. This took just under two minutes (pretty much the same as the previous release), while adding images was already lightning fast so we didn’t see much difference here either. However, dig deeper and you’ll find much more useful additions, such as the Separate Objects task. This scans your images, then crops any objects…

WARNING: JUNK AHEAD Junk offender: Browser notification spammers Junk doesn’t just sneak on to your PC through software – it can also catch you unawares while you browse the web. I was reminded of this while looking for a tool called AC3 Filter. This used to be a trusted, free way to add support for digital audio standards, such as AC3 and DTS, to your PC and I was curious to see if it was still around. A Google search directed me to www.ac3filter.net, where I found a link to the tool. However, clicking this took me to a web page where the only option was to allow browser notifications (see screenshot 1). You might think this would let you download the tool, but no. Instead, it just allows the…

Page turner This inkjet printer/scanner/copier is small and cheap – if you’re comparing it with office colour lasers. And it would be entirely reasonable to compare it with office colour lasers. It’s fast, has a full set of connections, and takes big tubes of ink instead of tiny overpriced cartridges that need replacing every five minutes. Compared with dinky consumer inkjets, on the other hand, it’s pricey and quite large. But attention to detail in the design takes the edge off that, with neat curves fusing black and white plastics into something more like advanced hospital equipment than a plastic desk accessory. Reasonable running costs will appeal to any who print in bulk A 250-sheet paper tray is built in, with an extra 500-sheet feeder optional, and the scanner has…

Winner of a five-star Buy It! Award in Issue 590 (page 29), RHA’s TrueConnect 2 are Scotland’s answer to Apple’s AirPods. Designed in Glasgow, this second edition brings significant improvements to an already impressive product. Battery life in each earbud now lasts up to nine hours, making a total of 44 hours away from the mains when you recharge them from the supplied USB-C battery case. That’s longer than most rivals. The buttons on each earbud have been replaced by touch surfaces, which respond perfectly to finger taps. Sound quality is just as excellent, with everything from crunchy bass to high orchestral strings clearly defined and stereo-separated in all genres of music. It’s been designed to isolate the audio you’re listening to, helping you block out distractions, while the dual…

What you need: Google Photos; Android or iOS phone Time required: 15 minutes Ever found yourself looking at a passage of printed text that you’d like to save to another document – for example, an article in a newspaper or magazine that you’d like to quote in an email or text? Well, you can start by taking a photo of it on your phone. Google’s Photos phone app will then be able to recognise the text in your image and copy it, so you can paste it wherever you like. Google Photos can also use Google Translate to convert almost any foreign-language text you come across instruction manuals, road signs, menus and so on – into English. Here, we’ll explain how to do both. STEP 1 Google Photos comes preinstalled…

VLC Free Android www.snipca.com/36257 The popular media player has been updated with features that make accessing and managing your media easier. As well as automatically detecting video and audio on your phone, it can connect to media servers on your network and has handy gesture-based controls for adjusting brightness and volume, or speeding forwards and backwards through whatever you’re watching. Opera Free Android www.snipca.com/36256 The latest release of Opera for Android has a neat trick: if you’re also using Opera on your PC, it will display a QR code on your PC that, when you point your phone’s camera at it, automatically sets up synchronisation between the two browsers. Alternatively, long-press the Opera icon and a QR-scanning option pops up, from which you can scan codes on posters, menus, and…

If your club is small, you may not think membership cards are necessary. You may know all the members by name, and they probably know everyone else too. But whatever the size of your club, it’s still worth having cards because they provide a sense of belonging. You may even be able to arrange deals with local companies so that members can enjoy discounts and other benefits when they show their card. If your club is larger, membership cards provide an efficient way of keeping track of everyone – each person gets assigned a unique number that you can log into a spreadsheet Here, we’ll explain how to use free design site Canva (www.canva.com) to produce professional-looking membership cards, although it also lets you create all kinds of document, from…

Facebook is donating £1m to the Bletchley Park Trust to help save jobs at the charity, which is in financial trouble as a result of the coronavirus lockdown. In August, the Trust said it was heading for a £2m deficit this year due to the prolonged closure during lockdown, and fewer visitors being allowed since restrictions were partially lifted. It said it would have to cut 35 of the 100 jobs at the site, and close many visitor activities. Facebook’s donation will save some of those jobs, and mean some exhibitions can continue. Announcing the donation (www.snipca.com/36329), Facebook emphasised how Bletchley Park’s codebreakers during World War 2 lead to great leaps in computing. It said: “Facebook simply would not exist today if not for Bletchley Park. The work of its…

WATCH OUT FOR… Amazon ‘account issue’ email scams What’s the threat? Scammers are stealing Amazon customers’ details by sending emails that claim they need to “verify” their account to fix a problem. The emails contain Amazon logos, and are written in a similar font and layout to those used in the company’s official messages. They say that Amazon has prevented you from buying or selling on the site because of an “account issue”. It asks you to click an orange ‘Verify Account’ button, which takes you to a site that looks like a genuine Amazon sign-in page. However, it’s fake. Scammers will steal any details you type into it. The scam adds urgency by claiming that if you don’t verify your account within 24 hours it will be closed permanently.…

I recently had an error warning on my Epson XP 600 printer telling me the ink pads had run out and needed replacing. I duly went online to find out how easy the job was. I’m an engineer and found to my surprise that it was well within my capabilities. I looked for the ink pads I needed and came across OctoInkjet (www.octoink.co.uk). I ordered the items and they arrived the next day. Having replaced the ink pads I then had to reset the printer. I ran into trouble here because the WIC Reset Utility told me to look for Internet Explorer. I couldn’t find it, so phoned up OctoInkjet for assistance. A very nice gentleman answered and not only told me how to enter the WIC code but also took me…

What can I use to adjust video-playback speeds? Q I often use YouTube’s playback settings to slow down videos. Is there a tool that will let me do this for other video and audio sources? Jeff Probst A If the video or audio is stored on your hard drive, VLC is the best tool to use (download it free from www.videolan.org). Load your file by dragging it into the VLC window or pressing Ctrl+O, then pressing the Play button. You can now decrease and increase the playback speed by pressing the [and] (left and right square bracket) keys respectively. To resume normal playback, press the = (equals) key. Alternatively, click the View menu at the top, then make sure Status Bar is selected. In the bottom-right corner of the window…

When people started to panic-buy hand sanitisers earlier this year, the bosses at Digital Growth Experts Ltd (DGEL) thought they were quids in. The London-based firm, which sells health and pet care products on Amazon and other sites, sent 16,190 spam texts to members of the public between February and April. The messages marketed the hand sanitiser – Zoono Body (pictured), claiming it was effective against COVID-19. After an investigation, the Information Commissioner’s Office concluded that DGEL “played upon people’s concerns at a time of great public uncertainty, acting with a blatant disregard for the law, and all in order to feather its own pockets” (www.snipca.com/36304). It promptly slapped the company with a fine of £60,000. So, who’s panicking now?…

What does it do? Memory, also known as main memory or RAM, holds the information your PC is using right now – all the programs that are open, the features of Windows they’re using and the files they’re working on. Your PC’s processor (CPU) only sees what’s in the memory. Data is read into memory from permanent storage (the hard drive or SSD) or from sources like web pages. How does it work? Types of silicon chip called random access memory (RAM) improved on earlier storage technologies by allowing the processor to go straight to the data it needs, instead of having to hunt backwards and forwards. The memory in your PC is dynamic RAM (DRAM), meaning it forgets the data when the power is turned off. That’s why you…

What is it? E Ink’s Kaleido is similar to the screens on ebook readers such as Amazon’s Kindle, but in colour. It’s becoming available in devices like the PocketBook Color (about £240, see www.snipca.com/36313, pictured). How does it work? The transmissive screens in smartphones and tablets emit light. E-ink, like printed paper, is visible because light around you bounces off it. So it uses much less power and may be more comfortable to read, but needs good light where you are. What’s the catch? Kaleido uses a colour filter in front of an e-Ink panel, which reduces resolution. In a book or magazine, black text is usually printed at 1200 dots per inch (dpi) and photos at 300dpi. The PocketBook Color shows text at 300dpi and photos at 100dpi. It’s…

What you need: Pay as you go SIM or VoIP number; old mobile phone Time required: An hour However careful you are about only giving your phone number to those who really need it, it’s probably spread much further than you imagined. Despite what it may say in the terms and conditions and the privacy policy of every form you’ve filled in, it’s almost certainly been shared many times over. If you’re not already getting automated calls about car crashes you’ve never been in or fake tech support, think yourself lucky. The only way to get off all these lists once and for all is to get yourself a new number – but why should you go to all that trouble? Doing so means you also need to give out…

TIP OF THE FORTNIGHT Transfer your photos and videos from Facebook to Dropbox I’d had enough of Facebook. I didn’t trust it anymore with my data (if I ever did), and it’s full of over-sensitive people moaning. Could I find a way of moving my photos and videos from Facebook to my Dropbox storage account? Yes I could! It was much easier than I feared. I just logged into my Facebook account then clicked the dropdown arrow in the top-right corner and selected ‘Settings & privacy’, followed by Settings. Next I clicked ‘Your Facebook information’ on the left. Then, in the middle, I clicked the blue View button next to ‘Transfer a copy of your photos or videos’. I typed my password then clicked the ‘Choose destination’ dropdown menu and…

WINDOWS 10 Remove ‘Quick access’ items in bulk Open File Explorer (press Windows key+E) and you’ll see a ‘Quick access’ section in the left-hand sidebar that lets you open recently accessed folders (if you can’t see this sidebar, click the View tab, then ‘Navigation pane’ and make sure the ‘Navigation pane’ option in the dropdown box is ticked). While this can help you navigate more quickly, it may contain folders you have no intention of accessing anytime soon. You can remove these by right-clicking each in turn and selecting ‘Remove from Quick access’ (if Windows added them) or ‘Unpin from Quick access’ (if you added them). A quicker way is to select the ‘Quick access’ option at the top of the section (see screenshot above) then, in the right-hand pane,…

What is it? A supercomputer being built in Cambridge to help medical specialists use artificial intelligence (AI) during research. It will be Britain’s most powerful computer. Wonderful. And how will that rank globally? It’ll be the world’s 29th most powerful supercomputer. Ah. So it’s not exactly world-beating? Well, yes, it’s behind machines built by Japan, China, France, the US and Italy, but ahead of any from Germany, Russia, Brazil and Spain. Mid-table, you might say. The UK actually has six supercomputers in the world’s top 100 (see www.snipca.com/36290). Who’s making it? US company Nvidia, which makes 80 per cent of graphics cards found in computers. It recently bought UK processor manufacturer ARM for a cool $40bn. But will the UK benefit from it? So it seems. Jensen Huang, Nvidia’s co-founder…

All PCs get slower as they age. Sometimes this is caused by hard drives degrading, but more often it’s because we expect them to run more demanding software, or we let them get cluttered with junk. My seven-year-old HP Envy Rove 20 PC, which came with Windows 8 but now runs Windows 10, is certainly feeling its age. It can sometimes take minutes to boot. I’d finally had enough, and decided to try all the methods that are meant to rejuvenate your system and make it start faster. My strategy was to time how fast my PC booted in its current state, then see whether each method would cut this. My first boot, without any improvements, took 50.3 seconds, which is faster than it normally manages, but is still painfully…

Why don’t I get CD information? Q In Issue 587’s How To, Nik Rawlinson used Windows Media Player (WMP) to rip CDs and to import the disc and track info. I followed his advice but get told the artist is unknown, and no track names. Am I missing something? Keep up the good work. Gordon Blyth A You’re not missing anything but it sounds like a particular WMP option that’s needed for this tool to work is disabled on your system. When launching WMP for the first time it asks if you’d like information to be retrieved from the internet, and plenty of privacyminded people understandably click ‘No’ unaware of this consequence Fortunately, it’s easy to fix. First, launch WMP and then press Control+M to reveal its menu bar. Next,…

While research to develop a COVID-19 vaccine is clearly important, I hope that someone somewhere is also trying to fix 2020’s second biggest problem: how to make photo software recognise faces wearing masks. If not, then cataloguing photos taken in this strange year could prove tricky. It occurred to me because I was keen to find a tool that could recognise faces even when they were blessedly free of masks. I’d heard good things about digiKam’s improved face-tagging tool, which came in version 7, released this summer (see Issue 588, page 19). Its developers claim it correctly recognises faces 97 per cent of the time, higher than the previous version’s 80 per cent. In its blog (www.snipca.com/36383) digiKam says the tool detects “blurred faces, covered faces, profiles of faces, printed…

Players of Microsoft’s Flight Simulator 2020 game are replacing some of the poorly rendered images with more accurate pictures from Google Maps. While the game’s graphics have been widely praised, Microsoft did have problems recreating some landmarks. These include Buckingham Palace, which resembles an office block in the game, and Sydney Harbour Bridge, which was shown as an ordinary road bridge. Microsoft made these images using data taken from its own Bing Maps. Gamers are now modifying these images using complicated techniques that extract the data from Google Maps to produce more accurate images. In one of the first examples shared online, a blocky Melbourne Cricket Ground has been made to look more realistic (pictured above). UK landmarks added or improved by gamers include Stonehenge (pictured left), the Angel of…

Time spent talking on mobile phones rose sharply during lockdown, as people stayed in touch with friends and loved ones. Figures from Ofcom’s Mobile Matters survey (www.snipca.com/36330) show that the average time spent on a mobile call rose from three minutes 40 seconds before lockdown to five minutes 26 seconds in the early weeks of restrictions being introduced. But Ofcom’s survey, which looked at how around 200,000 people used their Android mobile phones between January and April, also showed that more than one in five (22 per cent) didn’t make a single call in the first 11 weeks of the year. Ofcom says this was down to the rise in alternative methods of communication. These include sending messages on apps including WhatsApp and Facebook Messenger, and video-chatting on services like…

PayPal users have been urged to log into their accounts before 16 December to avoid paying an ‘inactivity fee’ of up to £12. The company is introducing the annual charge for accounts that have been inactive for 12 consecutive months. It defines “inactive” as an account where the user hasn’t sent, received or withdrawn money, or logged into their account. Inactive users will be charged either £12 or their entire PayPal balance, whichever is less. You won’t be charged a fee if you don’t have any money in your account, or your balance is negative. To avoid the charge, log into your account by 15 December, or make a transaction. This means you will have been “active” in the previous 12 months, so won’t be charged. If you no longer…

If you use Chrome to browse the web on your phone or tablet, you’ll now see alerts telling you when your passwords have been stolen. When you sign into a site, Chrome will send an encrypted version of the username and password to Google’s servers, where they’ll be checked against a database of stolen details. This information stays secret throughout – Google can never see your details. If your username or password have been stolen, you’ll see a warning, with a link to change your details. The alerts, which appear on both Apple and Android devices, are part of Chrome 86, which was launched in early October. They work only for passwords you’ve asked Chrome to remember in its Password Manager. To do this in Android, tap the three dots…

LEAD CASE Why won’t eBay help after a buyer conned me? Q In July, I sold a brand new pair of Bang & Olufsen headphones on eBay for £49.95 (£57.45 including postage). The buyer in France returned them via eBay’s return process saying they were defective. I didn’t examine them properly when they came back, so I refunded the buyer. I’ve since found the buyer swapped his older broken headphones for mine, and eBay won’t help. Can eBay just wash its hands of this criminal act? Dominic Price A Yes, we’re afraid it can. Under law eBay acts only as the buyingselling platform, not as the buyer or seller itself. Also, the protections it offers aren’t covered by law. They’re more like a warranty, which means they must stick to…

Make corrections to online records Reader David Cale recently discovered that his South Africanborn mother, who died in 1980, was born four years earlier than he previously believed: “As a result her death certificate information is now wrong,” he writes. “I would like to correct it to ensure the information is accurate”. David should first visit Gov.UK (www.snipca.com/36139), where he’ll find all the info he needs to make the correction, along with a downloadable form where he needs to fill in the new information. This costs between £75 and £90. However, David should be aware that his evidence (a South African baptism record) may not be considered acceptable proof of when his mother was born. He should call the General Records Office on 0300 123 1837 for further advice before…

Modern phones might be ridiculously powerful, but I still find them awkward to use. After a few minutes, my fingers start to ache and despite my Samsung Galaxy S8 having a relatively large 5.8in screen I still find myself squinting at it. Back in 2018 I was delighted when I discovered the Windows 10 October Update would include a new Your Phone app, promising to let me use my phone from the comfort of my PC. However, linking my PC with my phone proved frustratingly difficult, and once I finally got the two talking I wished I hadn’t bothered. I could use the Your Phone app to view my phone’s photo library on my PC (though only the latest 25 photos), send text messages (which, in my experience, rarely worked),…

Q My Packard Bell EasyNote TE, bought in 2012, is not so fast now, and sometimes freezes. A local PC engineer tells me it’s “past its best” and impractical to upgrade, unlike a desktop PC. But all I need is something for web browsing, emails, Excel and occasionally PowerPoint – and I do like my laptops. What’s your advice? Allan Whitehead A Modern laptops aren’t usually upgradeable, while it’s easy to add memory and storage to a desktop PC, or replace worn parts. But not many PCs last longer than eight years. Your laptop, good value in its day, has done wonderfully well. Right now, there’s a dearth of options under £500 except for Chromebooks, which have their own version of Microsoft Office but can’t run Windows, and small laptops…

iOS Keep notes on your iPhone home screen One of the more significant changes in iOS 14 is the introduction of widgets, which show live data like stock prices, the time and weather forecasts among your app icons. The free Sticky Widgets app (www.snipca.com/36244) makes one of the best uses of this feature that we’ve seen, letting you tap quick reminders, which remain visible on your home screen as though they’ve been stuck there using a Post-it Note (see screenshot below left). Once you’ve installed the app, longpress any icon on your home screen until the menu pops up and tap Edit Home Screen. Next, tap the ‘+’ symbol at the top of the screen, followed by Sticky Widgets. Swipe through the three styles to choose between small, wide and…

LIBREOFFICE CALC & MICROSOFT EXCEL Quickly add multiple rows and columns to a spreadsheet No matter how carefully you plan your spreadsheets, there will be times when you need to insert additional rows or columns. You do this, in Excel, by right-clicking the row directly after the place where you want to insert them, then selecting Insert (this inserts the row or column immediately in front of the one selected); Calc gives you the options of Insert Before and Insert After the row you’ve selected. If you want to insert more than one row, you’ll have to repeat this step multiple times. Instead, click the appropriate row, then select as many rows as you want to insert – in our example, we want to insert five rows before row 3,…

With the rise of instant messaging, you might think email’s days are numbered. Far from it. According to industry analysts Statista, nearly 294bn emails were sent last year – a figure that’s predicted to increase to 350bn by 2023. But are your emails really secure? As we explain in this feature, that depends on which email service you use and how you set it up. WHAT YOU CAN DO When you need to send emails containing particularly sensitive information (such as bank details or legal documents), we recommend using end-to-end encryption (E2E). Here, we’ll explain how this technology works and tell you about the powerful free email service that provides it. If the idea of moving to a new email service doesn’t appeal, we also guide…
