Are Your Devices Dangerous?

Modern tech seems plagued by product recalls, security vulnerabilities and other flaws. Jonathan Parkyn explains how to protect yourself from dodgy devices

When you buy a PC, laptop, tablet or any another device, the last thing you expect is for it to spy on you, expose you to security risks or catch fire. But a recent spate of horror stories in the news points to a worrying trend for faulty product lines and devices that are sold with built-in vulnerabilities, effectively turning your computer into a ticking time bomb.

But why is this happening? Which manufacturers are the worst offenders? And what can you do to protect yourself from potentially dangerous devices? Read on to find out.

A smaller, taller PC monitor

What most people seem to be looking for in a monitor these days – and what, therefore, monitor companies are most likely to try to sell you – is a huge widescreen display, typically 27 inches across the diagonal, with an ultra-slim bezel, a basic stand, and some fashionable features like high refresh rates to make games look smoother. But that’s not quite what some of us want. That size may be too big for a small study at home, and how comfortable the screen is to use depends less on whether it can update more than 60 times a second, and more on whether you can set it at exactly the right angle and height.

Don’t laugh and point, it’s rude

There’s a fundamental conundrum with laptops. To make them more compact, you reduce the size of the screen. That reduces the size of the keyboard. The trouble is, our eyes can get used to seeing more or less information on a screen, but our fingers trip up when the keys get closer together.

For years, manufacturers have accepted that they can’t square this circle. Now HP has made a breakthrough. It’s based on one simple yet brilliant insight.

Protect Your Eyes From Screen Glare

If you suffer from tired eyes after using your laptop or tablet, don’t put up with the discomfort. Arren Sayers explains how to prevent eye strain

Ever notice how a few hours spent staring at your computer or tablet’s screen leaves your eyes feeling sore and tired? That’s because looking at the backlight behind a screen is like staring at a low-intensity light bulb for hours at a time.

What makes computer displays especially damaging is that they produce ‘blue light’– a type of light that suppresses the sleep-inducing hormone melatonin. This not only makes it hard for us to nod off at night, but also leads to a disturbed night’s sleep when we finally do.

Here we’ll show you how to limit the effects of harmful light to keep you, and your eyes, in fine fettle.

Should you covet this Windows 10 laptop?

One of the best YouTube videos about computers – as well as one of the simplest demonstrations of Newtonian physics – is the one that shows an astronaut ejecting a floppy disk under zero gravity (www.snipca.com/19928). If, like us, you’re old enough to remember floppy disks, you’ll know they popped straight out, with a brisk spring action. So, just as Sir Isaac would have predicted, the 3.5in packet emerges and floats elegantly across the room, like something out of 2001: A Space Odyssey.
