It's been a busy week down the tech mines. We lost a good man in Windows XP, extracted a solid Samsung Galaxy S5 review and found a bad seam of internet danger when the two-year-old Heartbleed bug was discovered to be rotting secure websites from the inside out.
You'd be forgiven for struggling to keep up with what's what - but not for long. Here's the week's top tech news for your cribbing pleasure:

Heartbleed emerged the very week that Microsoft retired support for Windows XP. COINCIDENCE? Well, yes. But still, it could cause a whole new set of security issues for XP users. What are your options? The best bet is to upgrade to a newer version of Windows - but you could take the opportunity to give Linux a try. Or just sack it all off and buy a Mac. Drastic measures, but here's what to do with your old XP PC if you do.
Time for some good news: the Samsung Galaxy S5 is here! It's on sale today and comes with a bunch of freebies to boot. In our official S5 review, Gareth Beavis proclaimed: "The Samsung Galaxy S5 can be defined by one word: evolution." It's powerful. It's competent. It's… more of the same. So how many stars? You'll have to click to find out.
Also on sale today is the Galaxy Gear 2 - has Samsung done the unthinkable and put together a smartwatch you might actually want to wear? It certainly looks that way - the Gear 2 has a cool design, it's easier to use than its predecessor and looks durable enough to handle even the toughest work-outs. Read our Galaxy Gear 2 review here.

House of Ultra HD
Netflix's first 4K streams have gone live - the second season of House of Cards is now available in the eye-pleasing resolution.

The iWatch cometh
After some weeks of silence, the iWatch rumours are back with a vengeance. It's looking ever more likely that Apple will unveil its smartwatch in September alongside what we expect to be the iPhone 6.
