Does Blue Light Keep You Awake Or Not?

Scientists can't seem to agree one way or the other.



Everyone knows that using gadgets like phones and tablets before trying to sleep is a bad idea. The blue light emitted by their screens plays tricks with our brains, we’re told, making it hard to nod off and get a healthy 40 winks. This idea has become accepted wisdom in recent times, with technology companies now including blue-light filtering as standard in many devices. But new evidence has emerged, suggesting that blue light isn’t a problem at all, and that warm colours are, in fact, what’s keeping people up at night. So what’s going on?

What Is Openreach?

How the nation's main telecoms company works with businesses. 


Last week, the Labour Party announced a pledge to create a nationalised broadband service. Some applauded the other idea, while others ridiculed it. We’re not going to debate the merits of that plan here, but it did get us thinking about how we got to where we are today, in terms of the UK’s current telecoms infrastructure. Almost all phone and broadband lines in Britain are owned by one company: Openreach, a division of BT. How did that come to be, and is it actually good for consumers and businesses?

Why Deepfakes Are A Threat To Businesses

If criminals can create their own reality, how can they be stopped?


Deepfakes, realistic counterfeit videos created by artificial intelligence, are being posted online in ever greater numbers, says a new report. In the last year, there has been a 100% increase in deepfakes on the web, and while the vast majority (96%) of them are pornographic in nature, this technology also poses a major security risk for businesses – because as deepfakes improve, their effectiveness as a means to commit fraud also gets better.

Old Tech That Has Stuck Around For A Weirdly Long Time

Chances are you're still using one of these.


Most of the time, when a new technology comes out, it replaces whatever preceded it in a reasonable amount of time. CDs, for example, superseded floppy disks as a storage medium. And while there was a period in which people continued to find uses for those old floppies, the crossover wasn't overly long. CDs became the norm, then DVDs, then flash drives and then the cloud.

But some technologies just refuse to go away completely. Despite newer, better alernatives, they cling on for years. Here are just six of these hardy survivors.

Why Defences Of The $1k Apple Stand Don’t Stand Up

Apple is rightly getting flak for this pricy piece of metal 


This week, the technology community reeled in shock as Apple unveiled a monitor stand that costs $999.

Even for Apple, which has a long history of pushing its luck on pricing, this is clearly excessive. Not only were there audible boos when the stand was announced at the company’s World Wide Developer’s Conference in San Jose, it soon attracted criticism from the press. “There's no defending Apple's ridiculous $1,000 monitor stand,” said Wired. “A $999 monitor stand is everything wrong with Apple today,” claimed Engadget.

Why Your Computers Get Slower And More Unstable Over Time

And why hardware upgrades are inevitable.


Just like property leases and utilities, IT is an ongoing expense for any business. As well as subscription payments for services like managed helpdesk support, antivirus and Office 365, every few years most organisations have to replace hardware items – sometimes at great expense.
