Unlike most documents, it’s difficult to edit a PDF. Intentionally difficult: the big advantage of the Portable Document Format is that the person reading can’t modify it, either by accident or on purpose. When you share a PDF, you can be sure the people who receive it won’t be able to (easily) change it, unless it’s to fill out a form, and maybe sign it. This advantage quickly becomes a disadvantage if you need to alter a PDF and don’t have the original, editable file to hand....

Survival games aren’t a new trend; they’ve been popular with PC gamers for years, and come in all shapes and sizes; online, single-player, horror-themed, artistic and, sometimes, just downright weird. But despite the fact that the games are designed to try and kill you, gamers can’t get enough of the action. But not all survival games are created equally; while there are some phenomenal survival games that’ll provide hundreds of hours of enjoyable gameplay, there are some that are just frustrating to play....

Over the past few months, our home broadband connections have been pushed to the limit. Lockdown has meant everyone’s at home virtually all day and is using broadband for work, school, gaming and streaming. In response, BT has launched Dedicated Connection, a second broadband line which it says could be used for work. While fast broadband largely removed the need for the old-school ISDN lines, Dedicated Connection could make sense if you’re planning to work from home a lot more even when lockdown lifts....

One of the perennial student problems is this: what can I make for lunch? Or, at least, what can I make for lunch in 10 minutes, when all the shared cooking equipment in the kitchen is covered in an unidentifiable burnt-on mess? An air fryer will get you a long way toward solving these problems. It’s a shortcut to making quick, cheap and (hopefully) healthy meals. But can you bring one with you to college?...

DVDs used to be hassle-free in Windows 7, but since Microsoft removed Windows Media Centre and now charges for a DVD codec, many users have found they can’t easily play DVDs in Windows 10. Windows DVD Player costs £12.49, but that’s all it does. It won’t make a backup of your DVDs, and it won’t play discs if their region doesn’t match that of your DVD drive. In addition, Windows DVD Player doesn’t handle damaged or scratched discs well, doesn’t support Blu-ray discs either and has been known to crash following a recent Windows update....

At a Glance Expert’s Rating Our Verdict The Helix isn’t perfect, and its screen and battery life are adequate rather than impressive. However, it manages to provide high-end performance at a competitive mid-range price, and will appeal to gamers who want a laptop that won’t break the bank – or their back. Best Prices Today: Chillblast Helix It’s taken a while for these new laptops to surface, but following our recent review of Gigabyte’s impressive P35W v2 we now have another relatively sleek gaming laptop in the form of the 17-inch Chillblast Helix....

As we hit the anniversary of the first UK lockdown, the fact many office workers are still operating from dining tables around the country is one that few would have believed had they been told a year ago this is what the world would look like now. Our team of journalists also had to set up home offices and quickly realised that the information people needed was how to use the tech at their disposal to make it possible to do their jobs remotely....

At a Glance Expert’s Rating Our Verdict It’s hard to complain at this price, especially as you get a GPS receiver, but the D201 is far from perfect.
