The Raspberry Pi Zero is incredibly hard to get hold off. Hardly surprising, when you consider its $5 asking price.

Retailers such as The Pi Hut do replenish their stocks on a semi-regular basis, but even so you’ll have to act fast as even with a one-per-customer restriction in place, they sell out again almost immediately. Fortunately, there is a clever way to find out where the Pi Zero is in stock.

VirtualBox is an amazing virtualization tool, ideal for all kinds of software testing situations -- unless they involve booting from USB, where there’s no direct support at all.

There’s a workaround which will sort-of solve the problem, no additional software required, but it’s awkward and inflexible. Virtual Machine USB Boot is an interesting alternative, an open-source portable tool which makes it much easier to boot USB keys in both VirtualBox and QEMU.

There are numerous ways to keep your smartphone safe from prying eyes, and a lock screen protected with a passcode is a popular choice. But a newly discovered vulnerability in iOS 8 and iOS 9 means that iPhones and iPads could be accessed by attackers.

The vulnerability was discovered by security analyst Benjamin Kunz Mejri and it has been assigned a Common Vulnerability Scoring System (CVSS) count of 6.0, as well as a 'high' severity rating. Apple has been aware of the issue since late last year, but has yet to issue a patch.

Although there are lots of apps and services you can use for chatting to friends, Facebook Messenger is one of the better options because you can pretty much guarantee most people you know will have a Facebook account.

In addition to chatting with your friends you can now challenge them to play a game of chess, but only if you know the secret phrase to launch it, and the hotkeys used to pay the game.

Now that Microsoft is forcibly downloading Windows 10 onto unsuspecting Windows 7 and 8.1 users’ PCs there’s going to be a lot of unhappy customers faced with a new OS they never asked for nor wanted.

You can prevent this from happening by making sure the "Recommended Update" setting is unchecked on your PC, but if you fail to do this and accidentally allow the installation to go ahead (or maybe you tried Windows 10 and didn’t like it), the good news is it’s easy to roll things back to your original operating system.

Microsoft has changed the Windows 10 update from "Optional" to "Recommended". And by "Recommended" it means "You’re getting it whether you want it or not".

If your Windows 7 or 8.1 PC is set to install recommended updates automatically (because -- more fool you -- you just wanted it to be up to date and safe) then Microsoft will cheerfully download the new OS and start the installation process for you. Don’t want that to happen? Here’s how to stop it.

At the end of last year, the European Parliament and Council reached an agreement on the General Data Protection Regulation (GDPR) proposed by the European Commission.

The new rules, which will come into force in early 2018, represent the greatest change to data protection legislation since the dawn of the Internet. They will affect any organization across the world that handles data of European origin.

Data Privacy Day may not sound like the most exciting event to add to your calendar, but it serves as a hugely important reminder of the value of security. January 28 is the big day, and there has never been a better time to ensure that you are following best practice -- and there's no reason not to get started ahead of time.

35 years ago, Data Protection Day was launched, and over the years this evolves into Data Privacy Day. The aim is to improve privacy and security awareness online, on mobile, and on computers in general. Whatever you use your phone, computer and other devices for, there's plenty you can do to increase your security and privacy.

Microsoft Edge is deeply integrated in Windows 10, but while it’s a reasonable browser it still has a long way to go before it even comes close to rivaling the likes of Google Chrome or Firefox.

If you don’t use Edge, and I don’t, then its presence in Windows 10 might be a bit of an annoyance, especially when it sets (and occasionally resets) itself to not only be the default browser, but the default PDF reader too. Fortunately, you can block the browser, so you don’t need to ever worry about it again.

As you may already be aware, Microsoft has discovered that in certain situations the Surface Pro’s power cable could overheat, making it a potential fire hazard.

This is a problem that affects cables for the Surface Pro, Surface Pro 2, and Surface Pro 3 on devices purchased before March 15 2015 (in the US) or July 15 2015 (in all other territories). Microsoft has issued a voluntary recall, and you can now request a replacement power cord. The process is fairly simple, and this is what you need to do.

Fed up of Microsoft aggressively pushing Windows 10 on you? Happy to stick with Windows 7 or 8.1? You’re not alone.

Microsoft doesn’t make it easy to say no to Windows 10 (wouldn’t it be great if there was a "no thanks" button you could click to make the upgrade message and installation files simply go away?) but you can reject it using a Group Policy Setting or a registry tweak.

Windows 10 is a decent operating system, but Microsoft has seen fit to remove certain features found in previous iterations of the OS.

If you’ve upgraded to Windows 10 and have been disappointed to discover one or more of your favorite features have been removed, the good news is it should be possible to restore the missing functionality without too much effort.

Manually shutting down a PC is easy enough -- assuming you can find the power menu, anyway -- but automating the process takes a little more work. And even if you spend a while playing with your power options, shutdown.exe and Task Scheduler, it still might not deliver what you need.

Fortunately there’s plenty of freeware around to help automate all your shutdown, restart, sleep and other power-related tasks.

All companies -- from retail, to media, to IoT -- are increasingly becoming software companies. Data loss, security threats, service downtime and performance issues can sink a business. As a result, DevOps has evolved from an island of marginalized system administrators to an organization-wide cultural shift.

Companies like Netflix, Ticketmaster and Etsy understand that DevOps entails established processes, interconnected systems for monitoring and diagnosing, and org-wide vigilance about incident response. As our businesses continue to become more software-driven, Heavybit’s community of developer-focused entrepreneurs, advisors and investors provide tips and tactics to scale your DevOps efforts:
