Best Linux desktop of 2018

Note: Our best Linux desktop round-up has been fully updated. This feature was first published in November 2013.

The desktop is a critical aspect of your Linux experience, providing you with a user-friendly way to interact with your computer. Unlike Windows or Mac, Linux doesn’t tie you to a single desktop. Switching desktop environments is incredibly straightforward – just install a new one, log out and choose it from the login screen. You can install as many desktop environments as you like, although you can only use one at a time.

In this guide, we’ve rounded up seven of the most popular desktops, highlighting their strengths and weaknesses. Before you dive in, however, take some time to think about what you want from your desktop.

A desktop environment is more than the wallpaper which appears when you log in. It also includes a window manager and usually a set of utilities. It may come in the form of a pre-assembled package, such as Gnome or KDE, or it may be assembled by the distro maintainer, such as CrunchBang++’s Openbox or Puppy’s JWM.

Most desktops can be tweaked and skinned to look radically different, so if you like your current desktop’s look but not much else, you can probably customise – or even source a special version – of another environment to keep that familiar look and feel. Even when desktop environments come as part of a pre-assembled package, they may vary between distributions. KDE, in particular, can look radically different depending on your chosen flavour of Linux.

Functionality is another key concern. What features does the desktop offer, both in terms of the desktop itself and any core apps it bundles, such as a file manager or text editor? User-friendliness is another – how easy is the desktop to use? Are items laid out logically to your liking? Do you find yourself having to perform more clicks to access the key parts of the system?

If you have an older or slower machine, also consider how responsive your chosen desktop will be. Your PC may benefit from a lightweight environment such as LXDE rather than one with many visual effects such as KDE.

Ultimately your chosen desktop environment is a matter of personal taste and what your machine can handle. Take some time to explore the options listed here. If none of these seem to fit, we’ve also listed a few alternatives for good measure.

LXDE (Lightweight X11 Desktop Environment) is a desktop environment specially designed for older machines and those with few resources. Similar to the Cinammon desktop environment, the default layout is one panel at the bottom of the screen. You can also launch applications with a menu button at the bottom-left, exactly as you would in classic versions of Microsoft Windows. Emphasis has been placed on efficiency above all else. This is reflected in the choice of OpenBox as the default window manager.

This all makes for a fast and very memory-efficient desktop. Pixel, the desktop environment of choice for the Raspberry Pi operating system, is a modified version of LXDE. LXDE is also the desktop environment of choice for ‘Lubuntu’ – a lightweight version of Ubuntu. This is one of the main benefits of choosing LXDE as it’s highly customisable. After installing the desktop, you can choose to install new wallpapers, icon sets and even certain desktop themes using the specially designed LXAppearance.

Other core applications designed specifically for use with LXDE are extremely efficient too. The file manager (PCMan) opens quickly and supports dual panes. You can also run commands via the ultra-lightweight LXTerminal.

As it’s designed for barebones efficiency, any unnecessary features such as complex window effects or visually rich themes have been stripped away from LXDE. This may make for a rather stark desktop if you’re used to environments with more features such as widgets and animations.

Best for: Low resource use
Avoid if: You like graphical effects
Try on: Lubuntu
In a nutshell: A great desktop for older PCs

Gnome 3 is a revamped version of its predecessor (imaginatively named Gnome 2). The key user experience revolves around the new ‘Gnome Shell’ – the graphical part of the desktop environment. The shell does away with the old system of navigating via panels and menus in favour of a sidebar for quickly launching programs, an application ‘switcher’ and support for widgets.

When you arrive at the Gnome desktop, you’ll see a sparse top panel – click Activities to reveal a launcher, shortcuts to all the apps on your system, and a Search box. It won’t take you long to master this – ultimately one of Gnome’s strengths is its user-friendliness. On the other hand, it lacks features found elsewhere, and its quest for minimalism has led to core apps like the file manager losing key functionality such as split-screen views for easy file transfers.

Gnome is highly configurable, although you’ll need third-party apps such as the Gnome Tweak tool to get the most from it. It also supports shell extensions, but you can only install these through your browser, and they often break when Gnome gets a major update – other desktops handle such add-ons more adeptly.

If you don’t spend much time at the desktop and want to focus on your apps, then Gnome 3 will appeal, but it’s not for those who prefer a more traditional interface.

Best for: Minimalism

In a nutshell: Less is more

Cinnamon – the official desktop for Linux Mint – is forked from Gnome 3 with the focus very much put back on the desktop user. It utilises the underlying technology of Gnome, including forked versions of its core applications to ensure that they remain more functional than the native Gnome versions.

This ensure it’s able to deliver a polished desktop that’s immediately recognisable, particularly to users switching from Windows, with a menu button, app shortcuts and a system tray all packed into a panel that runs along the bottom of the screen.

It’s also highly configurable through a series of “spices”: themes, extensions, applets and floating desklets (Cinnamon’s equivalent of KDE’s widgets), all of which are managed directly through its own System Settings tool.

Although Cinnamon has made great strides in souping up its performance (the most recent release uses a pre-load mechanism to start swiftly after booting, for example), its reliance on Gnome 3 means it’s still relatively resource-heavy, while it has also acquired a reputation for being slightly buggy, although recent releases have steadily improved its robustness.

For our money, though, if you’re looking for a polished, instantly accessible desktop that takes the best bits of Gnome and wraps them up in a traditional setting, then Cinnamon is the desktop to try.

Best for: Hipsters
Avoid if: You have an older machine

In a nutshell: A traditional desktop

If you like the idea of the traditional desktop look, but want something that’ll run on slower or older machines, then Mate (pronounced ‘Ma-tay’, after the South American plant) is a potentially excellent alternative to Cinnamon. The developer website for Mate describes the project as an attempt to keep alive the classic Gnome 2 desktop.

It’s also forked from Gnome, but in this case, Mate is based on the older Gnome 2 release. This helps reduce its overheads, but you’re given a choice of flavours to install, including a “core” build with little in the way of extras to bog your system down, although all the key features are still covered (including Caja – a twin-paned file manager forked from Gnome’s Nautilus).

Mate opens with two panels – top and bottom – and you can add more, plus place them on either side of the screen. By default the bottom panel displays open windows while a series of menus in the top left-hand corner provides handy shortcuts to key parts of your system. Panels can also be extended via a number of additional applets, such as task launcher, power button, weather and so on.

A handy Control Centre shortcut gives you access to most system settings, including the few easily customisable parts of Mate itself (look under Appearance for options on switching and tweaking the theme). For maximum customisation, Ubuntu users might even want to try Ubuntu Mate, a specially built version designed to more seamlessly integrate with Ubuntu.

Ultimately Mate offers a reasonable compromise between the configurability of Cinnamon and the no-frills approach of lighter desktops like LXDE and Xfce – speaking of which, if Mate is still too rich for your PC’s tastes, read on…

Verdict

Best for: Older computers
Avoid if: You like GTK 3
Try on: Ubuntu Mate
In a nutshell: Gnome 2 lives!

Xfce has been around since 1996 and like Gnome is based on the GTK toolkit. It’s designed as a fast desktop environment which is low on system resource usage, but is rather eclipsed by LXDE, which is slightly more efficient while managing to look that bit more modern.

Nevertheless, Xfce has still got enough about it to stand apart: the main panel sits at the top of the screen by default, and we like the way its Application menu can be clicked easily from the top-left. The file manager Thunar has recently been enhanced and responds with lightning speed when opening folders or performing searches, although by default it doesn’t support more advanced features such as dual panes.

There’s little in the way of configurable options here, but where Xfce may win fans is with its highly customisable panels (via xfce4-panel). Right click on any panel to add more items such as a CPU monitor or mail notifier. The xfce4-panel utility also supports multiple panels, so you can have one at the bottom of the screen or on the side as a ‘deskbar’ if you wish. Control is granular: you can define the width, height and exact placement of each panel.

The window manager Xfwm is ultra-sleek and even includes its own compositing manager. It runs at similar speeds to other super-efficient window managers such as OpenBox, but is much more user-friendly.

Other bundled applications include the awesome graphical calendar app Orage, and Xfburn which can be used to author DVDs. You can also run commands via Xfce-Terminal which while being very sleek, also supports colour modes and even a dropdown interface similar to more advanced programs like Guake.

Verdict

Best for: Not too minimalist minimalism
Avoid if: You like a high level of configurability
Try on: Xubuntu
In a nutshell: Aims for simple, but not too simple

If you want to exert complete control over your desktop then KDE Plasma 5 is the desktop to choose – in some ways it’s more like a framework for building your own custom desktop than an actual desktop, although version 5 does ship with sensible defaults that give you something to start from. Note that some distros still offer version 4 by default, so be prepared to source it yourself (for example, via the kubuntu-ppa/backports repository).

Once started, the world’s your oyster – you’re presented with a single panel at the bottom of the screen and a handy tool box button in the top right-hand corner. From here great things can be made. KDE is largely based around widgets, which can be pinned to panels or left floating on the desktop itself. A large number are provided, but you can easily download more through the desktop too.

KDE also makes use of “activities”, which resemble virtual desktops, allowing you to customise your desktop for specific purposes – say when browsing the web or editing images.

KDE is unique among desktops in this roundup in being built on the Qt toolkit rather than GTK – this means it’s a little more resource intensive, particularly when updating; you may also find your existing apps don’t share KDE’s elegant look.

As a result, those searching for a fuss-free desktop with not too many bells and whistles will be better served looking elsewhere, but if you’re itching to build a desktop from scratch, then KDE should be first on your list.

In a nutshell: Tweaker’s heaven

Are you still searching for the perfect desktop? Try these alternatives…

Enlightenment

There’s no way to hide the fact that Enlightenment is about eye candy. Things fade, pop and shimmer with glee any time you do anything. Some people find all these distractions and window dressing (sic) a bit too much, but for others it adds a sense of humour to their computing.

Enlightenment describes itself as a desktop shell, which means it’s a desktop environment without any applications supplied. Since the styling is so different from the others (from which you’ll need to take software) this means the result is a system that looks inconsistent. However, if you like desktop effects, but don’t like KDE, Enlightenment may be for you.

Sugar

When Nicholas Negroponte founded One Laptop Per Child, the project kicked off with extremely limited hardware, so the developers set about creating a desktop environment that was both very light on resources and very child-friendly. Given that most of their target users had never seen a computer let alone used one before, it had to be easy to use as well.

Sugar is the result of this. It’s a little too simplistic for most uses, but it’s excellent for kids with its big blocky icons and a high-contrast colour scheme that make it great for their first digital steps. Try a Fedora spin here.

Openbox

We said at the outset of this article that a desktop environment is a tricky thing to define. Openbox (pictured above) is a perfect example of the reason why. A number of the other desktop environments, such as LXDE, use Openbox as a window manager. However, with some configuration, it can be turned into a desktop environment in its own right – which is what the developers of CrunchBang++ have done.

It’s a stripped bare environment that perhaps has something in common with Gnome 3, though not quite to that extreme. Its minimalism has endeared it to sysadmins and hardcore users who appreciate the lack of desktop bloat.

Puppy Linux

This distro has built a desktop environment around JWM, a slim window manager that’s not used in many other setups. As you may be able to guess, this is one designed to be frugal with resources. The end result is pleasant, though not spectacular, and works admirably on older hardware.

Puppy Linux is designed in the traditional fashion and does a good job of just staying out of the way. It can look a bit dated when compared to its more resource-intensive cousins, but many people find that endearing rather than annoying. Not many folks would pick this for a new machine, but it does a great job of keeping PCs running that would otherwise be scrapped.

Xmonad

If there’s one desktop environment that stands out from all the others we have here it’s this one. Before you start using it, it’s best to forget everything you think you know about how a desktop should work. Right, have you done that?

The desktop in Xmonad is split into tiles, each of which contains an application. You can shuffle the tiles around, change their size, and focus. You can also use the mouse within the tiles, but not to sort out the desktop like you would with windows. The result looks a little peculiar, but it is surprisingly usable once you get used to the new layout.

LXQt

So far we have explored a range of lightweight desktop environments for Linux, almost all of which use the GTK toolkit. This can cause problems for those environments based on GTK 2 as development has shifted to the newer, bulkier GTK 3.

Many people also prefer the look and feel of Qt. LXQt attempts to fill this particular gap. The current incarnation of LXQt is a culmination of the original project and code from an older project known as RazorQT. The stated goal of both projects is using the same Qt toolkit as KDE but without any bloat.

At present there aren’t many bundled applications, although it does incorporate its own terminal. There are also third-party tools such as the ‘lxqt_wallet‘ password manager which you can install after downloading the desktop environment itself.

LXQt currently doesn’t come with a window manager, but the project’s Github page reassures users that it will work with any arbitrary one such as Openbox, or Xfwm4 (the window manager for Xfce). The software is still in its early stages but is certainly one to watch.

If you ask ten computer users what they want from a computer interface, you’ll get ten different answers, so why should they all use the same desktop environment? The answer is simple – they shouldn’t.

Because of this, we’re not limiting ourselves to a single ‘best desktop’ because we don’t think there is one, but we’re not completely copping out. We’re going to pick our favourite desktop in four categories: traditional, new style, tweakers and outlier. We feel this recognition of different styles of computer use has become especially important in the past couple of years as the desktop possibilities in Linux have diversified significantly.

There has always been a range of desktops, but now, more than ever before, there are a range of good desktops. Not all of them will suit everyone, but everyone, we think, will be able to find a desktop that works well for them.

For the traditionalists

We have to say that there are no bad choices in the category at the moment. Xfce, LXDE, Mate, Cinnamon and KDE are all great desktops. They all have good and bad points, but we think that most traditionalists would be happy with any of them. However, there has to be a winner, and we’re picking Mate for the way it continues the Gnome 2 feel through to the present day.

For the brave new world

If you’re unafraid of new and avant-garde desktops, Gnome 3, with its upgraded graphical shell, is a clear winner. Although the initial desktop seems to be stripped bare, you can easily arrange windows into separate workspaces and launch different applications. Gnome also supports switching themes and adding widgets, though not to as great an extent as KDE (see below).

For the tweakers

Let’s be honest, there was only ever going to be one winner here and it’s KDE. Although an honourable mention should go out to Cinnamon now that it includes desklets. Enlightenment is another option, though we feel it doesn’t match KDE as a complete desktop environment. Maybe next time, KDE will have a challenger.

For the outliers

We’re going to pick the desktop that adds the most to the world of desktops. That is, the one that has the most useful features that can’t be done in any common environment. The winner offers a radically different way of doing things that we found surprisingly usable. In fact, we were tempted to switch. Hats off then to Xmonad (pictured above).

      

Microsoft’s OneDrive could soon help defend against file deletion disasters or ransomware

Microsoft OneDrive

It looks like Microsoft is planning to give OneDrive a nifty new feature – hopefully for all users – which allows for restoring files in the cloud service back to any point in the past, potentially helping to combat nastiness such as ransomware.

According to a presentation and subsequent tweet from Stephen Rose, senior product marketing manager for the OneDrive team, the ‘Files Restore’ feature will allow you to roll your OneDrive storage account back to any point you want, and it should be arriving in the next couple of weeks.

If this happens, it would be a major revamp of the existing ability to restore deleted files in OneDrive, which is currently limited to 30-days for most users (or a maximum of three months for those signed into work accounts, depending on admin settings).

It means that if users lose data perhaps by mistakenly having deleted something, or indeed as noted by Rose, via the ravages of ransomware, OneDrive could be a potential avenue of rescue, with file recall theoretically extending back indefinitely.

Although note that at this point, it’s not clear if the feature will be enabled for all OneDrive users, or just those subscribed to OneDrive for Business.

Data disasters

Some folks may be slightly alarmed at some of the privacy ramifications here, as it prompts the question: if files can always be restored, is nothing ever permanently deleted from the OneDrive servers?

Some may fret about that prospect, but most folks will doubtless welcome the capability as another handy safety net to guard against data disasters.

Microsoft is certainly working on making OneDrive a more tempting cloud storage proposition, and towards the end of last year, finally brought placeholders back for Windows 10 users (a capability that had previously been present in Windows 8, but disappeared with the launch of the new OS).

Apple says it isn’t slowing down your old iPad, Mac or Watch

With Apple having confirmed that it’s slowing down iPhones with aged batteries you might understandably be worried that the same thing is happening to your iPad, MacBook or Apple Watch, but you can rest assured that it’s not.

On a support page detailing the ‘feature’, Apple has confirmed that “This power management feature is specific to iPhone and does not apply to any other Apple products.”

So why is the iPhone affected and nothing else? Well, we don’t know for sure, but Apple is slowing older phones down to stop them unexpectedly shutting down, which can happen during performance peaks when the battery is older or at a low state of charge.

Bigger is better

GSMArena notes that as iPads have larger batteries than iPhones they’ll be better able to handle performance peaks, and they also tend to be charged less frequently than a phone, which means their batteries don’t wear out as quickly, all of which means that slowing them down should be less necessary. The same should also apply to MacBooks.

The Apple Watch, with its tiny battery, would presumably be susceptible to the same issues as an iPhone, especially since the battery could wear out similarly fast thanks to the regular charges it’s likely to get, but nonetheless Apple won’t throttle it – at least for now.

There’s no guarantee that the company won’t start slowing down other devices in future though, with the iPhone X, iPhone 8 and iPhone 8 Plus – all of which are currently too new to need slowing down – likely to be next in line.

      

The best antivirus software of 2018

If you’re looking for the best antivirus software in 2018 to keep you and your PC secure online, then you’ve come to the right place.

Even in this day and age, it is still essential to have the best antivirus software you can get your hands on installed on your PC (be it Windows or Mac), as malicious users are still coming up with ways to access you machine, be it hijackers grabbing your search page, or the latest ransomware encrypting all of your files.

If you’re running Windows 10, then you may think that the built-in Windows Defender is enough to keep you safe. Sure, it’s free and easy to use, but independent tests show its protection rates can be considerably lower than the leading competition. Also, by making it so widely-used, it also means that if a virus writer wants to hit as many PCs as possible, making something that evades Windows Defender will be their biggest priority.

There are free antivirus solutions that can be used with other tools to keep you protected, but they don’t always provide a complete suite of antivirus software tools that the best paid-for antivirus software provides. For that reason, if you want an all-round antivirus tool that provides up-to-date protection against the latest threats, then paying for antivirus software is your best bet.

This doesn’t mean you have to start spending big money, however, and we’ve come up with this list of the best antivirus software that features our very own price comparison tool to help you find the very best price for protection.

    In a world packed with free security software, Bitdefender Antivirus Plus 2018’s annual $39.99 fee may look expensive. Especially as this now only covers you for a single device, down from three last year.

    Still, there are compensations. Bitdefender’s engine is one of the most accurate and reliable around, for instance, loved by all the big independent testers.

    Web filtering blocks access to malicious sites, a secure browser keeps your online financial transactions safe, and there’s a password manager which auto-completes credit card details in web forms.

    An excellent anti-phishing module alerts you to malicious links in your search engine results, and blocks access to dangerous sites.

    There are one or two issues – it grabs more resources than average, and might conflict with some programs – but Bitdefender Antivirus Plus 2018 is still a likeable package which offers excellent detection rates, great performance, and more than enough bonus features to justify the price.

    Alternatively, you can purchase the Total Security 2018 edition for not much more. It adds a firewall, parental control, antispam, file encryption and more, and covers up to five PCs, Macs and Android devices (iOS is ‘coming soon’).

    If you judge an antivirus on the length of its feature list, ESET NOD32 Antivirus 2018 Edition might be a disappointment. There’s no firewall, password manager, file shredder, vulnerability scanner or any of the bundled extras you’ll often find elsewhere.

    This doesn’t mean the package is short on power, it’s just more focused on the antivirus fundamentals. ESET NOD32 Antivirus 2018 Edition comes with real-time malware protection, an anti-ransomware layer, exploit protection, URL filtering to block malicious websites, and modules to prevent attacks using PowerShell and malicious scripts.

    A Device Control module limits the risk of infection from other devices by controlling access to USB sticks, external hard drives, optical storage media, even devices connecting by Bluetooth and FireWire. It’s an unusual extra, but could make a difference if others are regularly plugging devices into your PC.

    ESET NOD32 Antivirus 2018 Edition isn’t aimed at beginners. The interface is clumsy sometimes, some features are very advanced, and even the Help isn’t always exactly helpful.

    Experienced users will appreciate ESET’s power and configurability, though. Above-average protection does a good job of keeping you safe, and a lightweight design ensures the package won’t slow you down.

    One of the new features in the 2018 Edition is the UEFI Scanner which protects you from threats that attack your PC before Windows has even started.

    F-Secure Antivirus SAFE is a great collection of antivirus software tools, and while it’s a bit more expensive than some of the other antivirus software on this best of list, the amount of features you get makes the cost worthwhile.

    With F-Secure Antivirus SAFE, you get the brilliant antivirus software from F-Secure, along with banking protection for safe online shopping, family safety tools and a device finder that lets you track your lost Android or iOS device, and if needs be remotely lock or delete it as well.

    The package typically receives maximum marks for protection from AV-Test, and generally scores highly with AV-Comparatives, too. They also say it can generate significantly more false positives than most of the competition, but how that affects you will vary depending on how you use your computer.

    The interface is a major plus. It’s extremely easy to use, lightweight, and for the most part you can just leave the app alone to look after your PC. The program has minimal effect on your system performance, and if you do need to intervene then you can generally solve any issues in a couple of clicks.

    In 2018, F-Secure Anti-Virus SAFE remains an appealing package: fast, lightweight, and able to run alongside many other security tools without conflict.

    Kaspersky Anti-Virus 2018 is a stripped-back security package which focuses on the core security essentials: web filtering blocks dangerous URLs, an accurate antivirus engine detects and removes threats, smart monitoring technologies track and reverse malicious actions, and that’s about it.

    Fortunately, what you do get works well. Very, very well. We’ve consistently found Kaspersky to be amongst the best at blocking malware, and removing it from an infected system, plus it’s regularly top-rated at sites like AV-Comparatives.

    The program is easy to use, too. A well-designed interface has just the right number of buttons and options – not too basic, but not complicated or intimidating, either – and there are plenty of on-screen instructions to explain how everything works. Even a beginner will be at home right away.

    If you just need accurate, reliable and consistent malware protection, Kaspersky Anti-Virus 2018 will serve you well.

    Norton AntiVirus Basic 2018 is a top quality malware hunter which can automatically protect your PC all on its own, but also offers plenty of tweaks, options and settings for those who need them, making it one of the best antivirus software suites in 2018.

    A handy URL blocker keeps you away from malicious websites, for instance. If that misses something, an excellent file reputation service recognises suspect downloads immediately. And if malware still finds a way through, intelligent behaviour monitoring kills it at the first sign of trouble.

    If you’re a more hands-on type, you can easily run scans on demand. Maybe set up and save custom scans to check just the areas you need. Even schedule them to run at a particular time, but only if your system is idle, and it’s not running on battery power.

    There can be problems with some of the browser extensions. The bundled Norton Identity Safe is a capable password manager when it’s running properly, but we’ve found the Chrome version sometimes stops working for no apparent reason. We’ve seen plenty of reviewers reporting similar problems, so there does seem to be a real issue here.

    Still, you don’t have to use Identity Safe at all, and Norton AntiVirus Basic’s main functions deliver on all fronts: it’s easy to use, has the configuration options experts need, comes highly rated by the testing labs, and is carefully designed to have the least possible impact on your system performance.

    Real-time malware detection, speedy cloud-based scanning, URL filtering to block malicious websites: Panda Antivirus Pro has all the goodies you’d expect from the best antivirus software.

    That’s just the start. A simple two-way firewall helps to keep your system secure. An application control system can define exactly what runs on your PC, stopping even some brand new and undiscovered malware. A virtual keyboard helps you enter confidential data without it being intercepted by keyloggers. There’s even a tool to build a bootable USB rescue disc, ready to remove even the most stubborn threats.

    Some of these bonus features are relatively basic. The Panda firewall does its job and can make you more secure, for instance, but it doesn’t compete with the standalone firewall competition. Experienced network users will probably want more.

    The simplicity does at least keep everything very easy to use. Options are organised in a straightforward Windows 10-like interface, with all the main modules just a click or two away. Even the firewall doesn’t need to know anything more than your current network location: Home, Work or Public Place.

    There’s not a lot of Panda test results from the independent labs around right now, but the figures we’ve seen show the company delivers above average protection, and overall Panda Antivirus Pro does a good job of keeping malware at bay.

    Trend Micro Antivirus+ Security is a capable antivirus package that’s simple to use with above average antispam and an effective ‘Folder Shield’ module to block ransomware.

    How good is it? The top testing labs all rate it highly for protection, although there’s some disagreement on the details. In particular, AV-Comparatives says it gives a high number of false positives, which could be a real nuisance. But AV-Test reports high levels of accuracy and no issues with false positives at all.

    If there’s a problem here, it’s likely to be performance impact. PassMark’s March 2017 Performance report assessed 15 security products on various performance-related benchmarks, and Trend Micro came bottom of the list.

    Our experiences with the product are a little more favourable: protection levels appear similar to Bitdefender, false positives are only marginally higher, and it doesn’t slow down our system noticeably more than anything else.

    We’d recommending running the trial for its full 30 days before you buy, then, to see if you notice any problems. But if you’re unaffected, its high levels of detection and excellent bonus features make Trend Micro a good choice.

    Just about every antivirus tool claims to be ‘lightweight’, but Webroot SecureAnywhere AntiVirus is the only one to really deliver on this front. Installation takes seconds, the program files barely grab 2MB of your hard drive, RAM footprint is tiny, and there are no bulky signature updates to tie up your bandwidth.

    There’s no compromise on features, though. Along with the core antivirus protection, there’s smart behaviour monitoring, accurate real-time antiphishing, a firewall and network connection monitor, enhanced anti-ransomware, and other interesting extras.

    It’s not easy to compare Webroot’s accuracy with the competition, as the big testing labs rarely evaluate the company’s products. But when they are reviewed, they generally score well, and our own tests show solid and reliable protection.

    There’s a lot to like about SecureAnywhere AntiVirus, and Webroot’s 70-day 100% money-back guarantee suggests it’s confident in the product, too. If you’re tired of overly complicated and bloated antivirus engines, Webroot must be on your shortlist.

The best cryptocurrency wallets in 2018

Bitcoin Core

Once you’ve bought Bitcoins (BTC) or other cryptocurrencies via an exchange (like Bitstamp), if you plan to spend your cryptocurrency right away, you can do so directly from the exchange. If you prefer to hang on to your digital assets, you’ll need a secure wallet to which you can transfer your virtual coins.

In this guide, we’ll explore five of the very best cryptocurrency applications available today for storing your digital wealth. Each of these programs allow you to generate private keys, which you can store safely, rather than trusting an online exchange which can be hacked or go out of business.

All of these clients are known as ‘hot’ wallets in that by default they’re connected to the internet at all times. If you are moving large amounts of Bitcoin, consider creating a ‘cold’ offline wallet to store your assets (see our guide to creating a secure cold storage Bitcoin wallet).

  • We also show you

    Bitcoin Core is the original BTC client and is available for Windows, Mac and Linux. Core is a ‘full node’ Bitcoin client, meaning that on first-run it will download the current version of the blockchain (currently around 160GB) by connecting to other nodes. It will then continue to download and process data about Bitcoin transactions.

    One advantage of this is that it’s much more difficult to link a specific BTC payment address to your identity as Core downloads data about all Bitcoin transactions everywhere. This also protects you against certain types of fraud such as someone trying to spend the same BTC twice, or fooling you into believing you’ve received funds you haven’t actually got.

    Core comes preconfigured to run through the Tor anonymizing network. This makes it very difficult for anyone to link sending or receiving BTC to your home IP address, ensuring your privacy. All this requires huge amounts of bandwidth – Core must be connected to the internet every day to stay in sync with the network.

    On first launch, Core will create a wallet file (wallet.dat) containing your private keys. By default anyone can access it, but you can encrypt the wallet with a password if you wish. (We’ve got a handy guide on setting up Bitcoin Core).

    Electrum has been around since 2011 and works with Windows, Mac and Linux. It’s one of the most popular ‘thin’ wallet clients, in that instead of downloading the entire Bitcoin blockchain, it connects securely to other servers to verify your BTC balance and process payments. This means you can set it up in minutes and it takes up very little space on your hard drive.

    Electrum uses a ‘hierarchical deterministic wallet’, in that when you first launch the program it generates a random ‘seed’ of 12 dictionary words, from which it derives the keys necessary to spend and receive BTC. Electrum displays the seed as you create your wallet and requires you to write it down. This means that if you lose access to this version of Electrum, you can easily reinstall it on another machine and use the seed to restore your BTC.

    Unlike the Bitcoin Core client, Electrum offers you the option to encrypt your wallet file during setup, although you can choose to leave it unencrypted if you wish. You can also use Electrum in ‘cold storage’ mode to create a ‘watching only’ wallet. This allows you to receive Bitcoin payments and see your balance, but not spend the coins, which may be useful if you’re buying BTC as a long-term investment.

    As a ‘thin’ client, Electrum relies on other servers for payment information, making it more vulnerable to certain types of hacking than ‘full nodes’ such as Bitcoin Core. See here for more information about how Electrum tries to protect you from this.

    Jaxx

    Jaxx was first developed in 2014 and serves not only as a Bitcoin wallet but an app which can store multiple cryptocurrencies such as Litecoin, Dash, Ethereum and Bitcoin Cash. Ripple is not currently supported but the Jaxx team have hinted they may support this feature in the future. (For a full list of supported currencies see here).

    When first run, Jaxx displays a 12 word ‘master seed’ similar to Electrum which you can write down and use to restore your wallets if you lose access to the original program.

    The interface is deceptively simple in that you can quickly and easily switch between wallet balances. Jaxx has also integrated Shapeshift support. This functions as a built-in currency exchange, allowing you to quickly exchange crypto balances, for instance to convert DASH to BTC. You can view your updated balances as soon as processing is complete.

    Jaxx is available as a Chrome extension as well as for Windows, Mac and Linux. There’s even a mobile app, so it’s likely you can view all crypto balances from a single device.

    The software is closed source, however, so cannot be reviewed by the community in order to hunt for security bugs. Note that one such bug was discovered in June 2017 which allows someone with access to your machine to extract your master seed and steal your coins. Until this is fixed we recommend using Jaxx only for storing and exchanging small amounts.

    Rippex

    Ripple is one of the top five cryptocurrencies in terms of capitalization and although it was designed to facilitate transactions between banks, many individuals also use it for speculation and to make payments.

    Unlike more popular currencies like Bitcoin, the official desktop client is no longer maintained by the original creators. Fortunately the community has continued to maintain it in the form of Rippex.

    Aside from being seemingly the only desktop client available for Ripple, Rippex is very easy to set up. On first-run it generates a ‘secret key’ which you can write down to restore your wallet in case anything happens to it. The client also requires you to encrypt your wallet file with a password, making your money harder to steal.

    In order to activate your wallet you have to pay a fee of 20 XRP (around $43 at current exchange rates, which is about £32). Once you’ve done this, you can set up a ‘cold’ offline wallet if you prefer to store your secret keys offline for safety reasons.

    If you want to store your XRP outside an exchange but don’t want to pay the fee for Rippex, you can also generate a paper wallet instead from http://ripplepaperwallet.com. The website will load the necessary code into your web browser – be sure to disconnect from the internet before creating the wallet.

    Rippex is available for Windows, Mac and Linux.

    Exodus

    Exodus is a multi-currency wallet and can hold various types of coins and assets. The setup process is very simple. Like Jaxx, you create a 12 word ‘master seed’ which you can write down and use to restore your wallet if you’re no longer able to access the original. (Incidentally, if you’ve previously created a master seed using Jaxx, Exodus can restore these too). Once setup is complete, Exodus will also prompt you to choose a password to protect your wallet.

    Your digital assets are shown in a user-friendly pie chart. Unlike the other wallets we’ve discussed here, you can also choose different ‘skins’ to make your client easier on the eye. Use the localization settings to change the default currency (USD) to your home currency if necessary.

    The wallet software also supports exchanging crypto-assets and currencies using Shapeshift, and even lists the percentages of assets you hold as part of your ‘portfolio’. Sadly Dogecoin is no longer supported.

    Exodus is also not 100% open source. The company claims on its website that doing so would give away trade secrets and make it easier for hackers to create bootleg versions of its wallets. In light of this, if you use Exodus you’ll have to trust that there are no undisclosed security bugs or backdoors built into the software.

          

The best cryptocurrency mining software 2018

If you’ve decided to take the plunge and have bought your own Bitcoin (BTC) mining hardware or mining rig, your next step is to connect to a mining ‘pool’. This allows you to share your machine’s resources over the internet and receive a portion of the mining profits in return.

There are a number of programs available to help manage your crypto-mining. In this guide, we’ve explored five of the most popular. If you’re an experienced computer user, you may prefer to install the free operating system Linux and make use of one of the text-only programs such as CGminer.

If you prefer to keep things simple and are sticking with Windows 10, mining clients with a GUI such as MultiMiner may suit you better.

Before getting started, if you want to be sure a mining program will work with your particular device or operating system, the Bitcoin Wiki has a very helpful list.

  • We also show you

    CGMiner has been around for over six years and is coded in C, meaning it’s compatible with almost all operating systems. It works via a simple command line interface and supports multiple mining pools and devices. It’s primarily designed to be used with hardware mining devices but can make use of any GPUs connected to your machine as well.

    On first run, CGMiner will ask you to enter the URL, username and password (if necessary) for your mining pool, and it will automatically detect any hardware you have connected such as an ASIC device.

    Although you have to work with CGMiner via the command line, the layout is very easy on the eye: mining devices are listed at the top and you can use simple keyboard commands to change your settings (e.g. to enable verbose mode or detect new hardware).

    During our tests using CGMiner 4.9.2 on Windows 10, we found that Windows Defender and our antivirus software tried to block the download. This may be because hackers using their own versions of this program could secretly install CGMiner on someone else’s machine to mine for their own benefit. You can configure your system to make an exception for CGMiner if you wish, or use the Linux version.

    The Bitminter Mining Pool has been around since 2011, and as one of the longest-running and most reliable services out there, it’s perhaps unsurprising that its creator Geir Hansen has also produced an excellent mining client too.

    The Bitminter client has an extremely clear graphical interface and can work with GPUs and external ASIC devices equally well. A simple dial on the left displays your hashrate in MH/s. Simply click ‘Engine Start’ to begin mining.

    You can check progress at any time by reviewing the ‘Stats’ section which lists vital info such as the number of proofs of work accepted/rejected by the server, as well as the time spent working. You can reset these values at any time.

    The Bitminter client also has a text console at the bottom of the window which provides you with updates such as when a device is connected, or when it has successfully connected to a mining pool.

    The software has been designed for use only with Bitminter’s mining pool. This means you’ll need to create an account via the website. You also need to be happy with the location of Bitminter’s servers (US and Europe), as well as the way in which the company shares mining rewards.

    BFGMiner is based upon the aforementioned CGMiner, but is designed specifically for ASIC mining hardware. The client is also compatible with FPGA (Field-Programmable Gate Array) devices and can be configured to work with some graphics cards – but it’s unlikely you’ll make a profit from these.

    As BFGMiner has a narrow focus, it has more features to allow you to tinker with mining devices, such as overclocking and using a remote interface. It also monitors the temperature of most devices and can connect to multiple mining pools. Furthermore, BFGMiner will stop connecting to unreachable pools, saving you precious system resources.

    The interface is text-based, but as with CGminer, options are very clearly laid out. You can make use of hotkeys to perform routine tasks such as monitoring pools, identifying devices and enabling extra features.

    Besides offering a simple text interface and an arsenal of features, BFGMiner is available for Windows and all major flavors of Linux. BFGminer can be installed on a Raspberry Pi, too, as part of the free Minera operating system.

    MultiMiner is a graphical frontend for BFGMiner. As such it has many powerful features but is also much kinder to newcomers.

    When you first install and launch Multiminer, the application will guide you through the process of entering your pool information, using helpful tooltips to explain potentially unfamiliar terms.

    After setup is complete, MultiMiner will automatically scan for mining devices and list their details in a helpful table, such as the pool used and average hash power. Most importantly, the client will also display your daily projected profit with your current mining hardware.

    You can use the ‘Pools’ tabs to connect to multiple pools if you wish. The ‘Strategies’ section provides an easy way for you to choose how you want to mine: for instance you can choose to mine automatically based on which coin is most profitable, or choose to mine coins with low difficulty.

    During setup the software developer requests that you send 1% of your profits to his wallet as a way of saying thank you for creating this awesome mining software. This is entirely voluntary – you can enable/disable this from within the app in the ‘Perks’ section.

    Multiminer is cross-platform but you need to install additional software to get it working on macOS and Linux.

    EasyMiner serves as a graphical frontend for the mining programs CGminer and CPUMiner. On first run, EasyMiner enters ‘MoneyMaker’ mode which allows you to automatically create a paper Litecoin wallet and start mining right away with a private pool. As convenient as this is, it’s unlikely to generate much profit at the current difficulty rate.

    The dashboard has a neatly laid out interface to allow you to configure mining pools, amend network settings and view your wallet. You can also use the settings feature to enable ASIC hardware such as an Antminer. This done, simply click ‘Start Mining’ to begin.

    EasyMiner includes a console which informs you of the progress of CGminer (cgminer.exe) and CPUMiner (minerd.exe), which by default are used to mine Bitcoin and Litecoin respectively. There doesn’t seem to be an easy way to switch off CPUMiner if you’re only interested in Bitcoin.

    During our tests on Windows 10, Avast Antivirus also automatically removed both the main EasyMiner program and CPUMiner, as malicious hackers have previously installed their own versions of these programs on other people’s machines to mine coins for themselves as part of a botnet.

    If you’re interested in EasyMiner but don’t want to deal with antivirus alerts, the program will work on Ubuntu Linux using Wine (see here for more info).

Best Mac apps: the best macOS apps for your Apple computer

The best Mac apps are here to make your macOS High Sierra experience better than that of someone using Windows or Linux. After all, it’s the Mac software that keeps us brand loyalists coming back to the Jony Ive-designed catalog of expensive goodies. While Apple packs plenty of useful apps pre-installed on every Mac, there’s a lot more out there than immediately meets the eye.

The best Mac apps span a number of different categories, so admittedly not everything on this list is going to tickle your fancy. There’s Atom, a text editor designed for coders, which is obviously going to appeal to a limited audience compared to something like Evernote – the best note-taking app, hands down.

They aren’t all available on the Mac App Store, but they are all worth your consideration. Without further ado, keep reading to the next slide for the best Mac apps you can download today. From freebies to costlies, these are the applications that will breathe new life into your MacBook or Mac desktop in 2018.

No brand of computer is without its annoyances. For so long now, it’s been impossible to use our MacBooks – unbound by the chains of a power adapter – while video outputs to an external monitor. As we all know here at TechRadar, Apple’s laptops automatically enter sleep mode whenever the lid is closed. For the lot of us, this can be a huge inconvenience should you prefer the sheer magnitude of a monitor as opposed to a 12- or 13- or 15-inch laptop screen.

Luckily, Amphetamine makes it possible to continue using your MacBook while closed. Previously you could accomplish this using a similar application called Caffeine, but we prefer the UI features you get with this freebie. In addition to fitting in naturally with the rest of your Menu Bar items, Amphetamine also supports hotkey commands as well as deactivation reminders, not to mention there are no pesky advertisements in sight.

While Windows has been able to snap programs to the edge of the screen since version 7, Apple’s solution didn’t arrive until OS X El Capitan. What’s more, even then it lacked some of the comprehensiveness of Microsoft’s alternative. Fortunately, HyperDock gives us that full-fledged functionality we so desperately crave, allowing anyone with a Mac to administer to the app Dock and windows all the same.

For windows, you can drag an app to the left or right edges of the screen (or the corners) and it’ll automatically fill that space. This makes it much easier to be productive on the desktop without wasting time dragging windows from the corners. For the Dock, hovering over apps activates something similar to Windows 7’s thumbnail previews, providing overviews of windows that can be accessed by a click or closed directly from the preview. Handy.

  • Price: $79.99/year (Home & Student) Around £60 or AUS$100)

If you’ve bought a Mac and miss some of your old Windows programs, don’t worry – Parallels Desktop 13 can bring them back. Instead of having to dual-boot your Mac into a Windows partition, Parallels Desktop 13 allows Windows and macOS Sierra to co-exist side-by-side, and you can even run Microsoft-only programs such as Visual Studio 2015, or the Windows versions of the company’s Office 365 apps, alongside your native macOS ones.

All you need is a Windows 10 license – so prepare to buy one if you haven’t already. Or, alternatively, you can use Parallels to try a handful of free operating systems including Chromium (a free distribution of Chrome OS) or Linux Debian. The latest version of Parallels in particular has seen improvements such as Touch Bar support, better resolution scaling for Retina displays and picture-in-picture for using other operating systems in conjunction with macOS.

If you’re anything like us, you’ll hate working with one monitor or screen. Portable monitors are still fairly expensive (and not to mention bulky), and luckily you can use an iPad instead using a nifty app called Duet. Developed by ex-Apple engineers, it works by tethering your iPad to your Mac using one of Apple’s Lightning cables and firing up the app on both devices.

You can then drag windows and apps onto your iPad’s display just like you can a second monitor, and if you have a more recent iPad with a Retina display then you’ll get the full benefit of all those pixels. Just know that the bandwidth isn’t quite what you would get with a proper monitor, so it can be a bit laggy when you notch the quality up. But it’s still more than usable for reading websites, typing up documents and watching videos.

  • Get it from: Atom
  • Price: Free

Atom is a text editor that’s primarily designed for coders, but its flexibility and customization options make it a viable option for many different types of users. That’s because of two reasons: first, you can download a number of different Packages – effectively plug-ins – to make it bend to your will. It can be transformed into a Markdown editor for writing blog posts, for example, or you can hook it up to Evernote for storing notes in the cloud.

There’s at least 10 different word counters out there, and you can even add typewriter sound effects as you hammer out your delicious prose. Atom is also infinitely customizable on the visual side thanks to an editable back-end, allowing you to do anything from changing the font size, line height and colors to giving the caret Word 2016-like elasticity.

Whether you’re an aspiring rockstar or superstar DJ, Logic Pro X is one of the best music creation apps on the Mac. Developed by Apple itself,76 its accessible interface hides a ton of advanced functionality. The latest version comes with a slick new design, 64-bit architecture and new session drummer that will save you having to shell out for a drum machine.

It also works in natural harmony with iPads, providing a touch-based alternative method of creating song structures to dragging and dropping blocks in the main visual editor. Whether you’re a seasoned producer already (Sia used the app to record her hit song ‘Chandelier’) or are looking to upgrade from Garageband, Logic Pro X likely has what you need.

A simple app but an important one, to-do app Wunderlist’s strength lies in its cross-device functionality. It’s available on Mac, PC and Android and iOS, allowing you to pick up where you left off wherever you are using macOS’s Handoff feature.

Once you’ve created a list you can schedule reminders, add notes and embed it into the macOS Notification Centre using a widget. Team-based features are unlocked by signing up to Wunderlist’s Pro option for a yearly fee, and you can add files of any size without running into limits.

Evernote has morphed into a mighty note-taking app over the years. While some people will say that it’s too bloated, the sheer number of things that you can do with it still makes it best-in-class. You can type up notes, obviously, organizing them using a combination of folders and tags. You can even embed Google Drive documents, which are accessible in a click.

There’s also the ability to set reminders, share notes with friends, find information related to notes using Evernote’s ‘Context’ feature, create lists, and favorite notes that you frequently return to. Better yet, all of your notes are synchronized using the company’s servers, making them accessible on nearly any PC (through a browser or the native Evernote app) or mobile device in the world. The paid version lets you use Evernote with more than two devices while upping the amount of data you can sync each month.

GIMP (standing for GNU Image Manipulation) is one of the best free image editing apps out there. It’s a great alternative to Adobe Photoshop and comes with a massive array of professional-quality functions that let you tweak existing images saved in a range of formats or create fresh ones from scratch. Features include layers, highly customizable brushes, automatic image-enhancing tools and filters. You can do even more with it using plug-ins, which are available to download from the GIMP Plugin Registry.

  • Get it from: App Store
  • Price: £34.99 (around $45/AUS$60)

Ulysses is one of the best “distraction-free” markdown editors out there today, balancing features with simplicity and beautiful design. Unlike Word 2016, or even Apple’s own Pages, Ulysses hardly features an interface at all. This allows you to get on with writing without being distracted by superfluous buttons and menus. The app uses its own brand of Markdown — a type of text formatting engine — that lets you highlight your writing in a way that makes organizing it simpler, and a vast number of export styles formats it in an attractive way once you’re finished.

There’s a handy attachments bar on the right-hand side that features an attractive word counter and lets you write notes to assist you in your writing. Notes can be accessed anywhere thanks to iCloud support, so you can pick up your iPad and carry on where you left off using macOS’s Handoff feature.

If you’re a gamer who takes pride in the fact that you use a Mac, whether for work, school or leisure, Nvidia GeForce Now will silence your biggest critics. Since the dawn of time itself, it’s seemed as though PC gamers have shut down the prospect of using a Mac to play triple-A video games. The graphics weren’t there, and neither was the library.

Nowadays, we live in the era of streaming. You don’t have to download your TVs and movies – you can stream them on Netflix or Amazon Prime. Why should games be any different? Well, with GeForce Now, they’re not. You can stream PlayerUnknown’s Battlegrounds, Overwatch and more at the highest settings from the comfort of your MacBook or Mac computer.

      

Best ASIC devices for Bitcoin mining in 2018

If you want to get started with mining your own Bitcoin (BTC), these days you need ASIC (application-specific integrated circuit) devices, which are specifically built for the purpose.

In this guide, we’re trying to help you become a profitable Bitcoin miner by highlighting five of the top ASIC mining devices on the market today.

Since everyone is jumping on the mining bandwagon, these devices can be expensive and difficult to buy. In most cases you’ll also need to purchase a good quality PSU (power supply) to ensure maximum efficiency.

Your main consideration when purchasing a device should be how soon you’re likely to see a return on your original investment. This is determined by the hash power of the device – i.e. the number of BTC it can generate daily – minus your electricity costs, mining pool fees and current mining difficulty.

To help you make your decision, we’ve listed the current price, hash rate and power usage of each device.

While these numbers are helpful, we encourage you to use a profitability calculator such as the one available from Coinwarz before ordering to estimate your return in BTC. Remember that you’ll also need to pay electricity costs and mining pool fees, as mentioned. The profitability calculator allows you to enter these to calculate your ROI (return on investment) more precisely.

The exchange rate between Bitcoin and fiat currencies is very volatile, so if you want to cash out quickly, register with a BTC exchange such as Bitstamp (see our guide on registering with Bitstamp).

  • We also show you

    The Antminer S9 is manufactured by Bitmain, the largest and most well-known mining equipment manufacturer in the world which has been going since 2013.

    The Antminer S9 is one of the most popular ASIC mining devices out there, and other mining hardware is often benchmarked against it. The S9 is also generally considered to be the most energy-efficient miner on the market today, although this will vary depending on electricity costs where you live and the type of PSU used with it (the latter must be purchased separately). Bitmain’s APW3++ power supply currently retails for around $100 (about £75).

    This extra efficiency comes at a price, and this isn’t the cheapest ASIC miner on the market. That hasn’t stopped the S9 being in very high demand, though, due to its commendable efficiency. Indeed, at the time of writing, the unit is sold out on Bitmain’s website, but it should start to ship again later this year. You can buy units from Amazon and auction sites like eBay, although prices are much higher and units may not be covered by Bitmain’s warranty (buyer beware, as ever).

    Bitmain regularly improves the specs of S9 units, so if you buy second-hand, make sure to check the exact hash power offered. The most recent units due to be shipped out in March 2018 offer an optimal hash rate of 13.5TH/s.

    The Antminer S7 was manufactured by Bitmain and is the predecessor to the S9. Since the S9 arrived, many miners have upgraded, flooding the market with relatively cheap used S7 devices.

    Although the S7’s hash power is only around a third that of the S9, due to the lower cost and the fact that many second-hand units come with a PSU pre-bundled, you may see a faster return on your investment than with the S9. The S7 may also generate less heat and noise than the S9.

    If you do decide to purchase an S7, be sure to check how long it’s been in operational use to decide how reliable it might be, and furthermore, check the seller’s refund policy in case it develops a fault after you buy. If the unit does come with a PSU, make sure it’s a good quality effort for maximum energy efficiency, such as Bitmain’s own AWP3++ power supply which also works with the S9.

    Even with a high-end PSU, the S7 is still not as energy-efficient as the S9 – on average it consumes 0.25 Joules of power per Gigahash. The S9 is over twice as efficient, requiring less than 0.1. You may still be able to generate a reasonable profit with the S7 if you buy more than one unit and/or use renewable energy such as solar power.

    Avalon, an offshoot of China-based firm Canaan Creative, was amongst the first firms to manufacture Bitcoin-specific ASIC chips, so it’s safe to say that the company knows what it’s doing when it comes to Bitcoin mining hardware.

    Like its predecessor the AvalonMiner 6, the 7 series has had generally good reviews with miners praising Avalon’s innovation in pioneering the A3212 16nm chips employed in the units, as well as how quiet these devices are when running.

    The AvalonMiner 761 supports cluster mining via a specialist AUC3 ‘AvalonMiner Controller’, based on the Raspberry Pi, which can support up to six devices. The AUC3 controller costs around $80 (£60) and can be connected to others to form larger clusters. For instance, four AUC3 devices could each connect to five AvalonMiners allowing you to manage 20 AvalonMiner 761 units with a staggering combined hash power of 176TH/s.

    You will also need to purchase a PSU separately for around $150 (£110). In total, this may still cost less than purchasing a used S7 unit. The Avalon 761’s greater hash power and energy efficiency means you’ll likely see a slightly faster return on investment.

    Canaan offers bulk orders (60 units or more) directly on its website. If you only want to buy a few units, the firm also has a list of official distributors. Despite glowing reviews, the devices aren’t as well known as Antminers, so if you’re new to mining, you may not find much help online.

    The M3, which was released in late 2017, is manufactured by Chinese firm Pangolin Miner. The manufacturer’s website not only provides detailed information on the miner, but an excellent tutorial video on getting set up. This includes connecting the device via Ethernet and configuring your mining pool settings via the M3’s web interface.

    While the hash rate is slightly less than the Antminer S9, this unit is far cheaper, meaning you could see a return on your investment in around the same time. While the device draws a lot of power, according to a detailed review on the Bitcointalk Forum, the M3’s built-in fans dissipate the heat quickly and it’s no noisier than comparable miners like the S9. The bundled PSU is also extremely efficient (over 90%).

    At the time of writing the M3 is currently sold out of batches shipping in February and March 2018, although the manufacturer hopes to make more available later in the year. Once your unit arrives you’ll enjoy a 180-day warranty against defects, the longest of all the devices we’ve highlighted here.

    The AvalonMiner 821 is a huge improvement on its predecessor, containing 104 A3210 16nm chips, giving it a reliable hash rate of over 20% better than that of the AvalonMiner 761.

    The 821 also has a power efficiency of 0.109 Joules per Gigahash, which is about 10% less than the Antminer S9 (at just under 0.098). As the hash rate is also lower than that of the S9, your decision on whether to choose the AvalonMiner 821 will probably revolve around price considerations.

    At the time of writing, Avalon has announced the 821 on its page and is offering the device for sale in bulk quantities. The listed price above is for 1/60 of the minimum order quantity of 60 units, so will likely increase over time. Avalon’s official redistributor BlokForge has also listed the AvalonMiner 821 for sale in individual units, but the price is still to be confirmed.

    Just as with its predecessor, you need to purchase a PSU separately which should cost around $200 (£150). Buyers will also be able to cluster-mine by connecting up to five 821’s to Avalon’s AUC3 controller, increasing hash power considerably.

Windows 10 preview beefs up do-not-disturb feature and sharpens Edge browser

Windows 10 Quiet Hours

Microsoft has pushed out a new preview build of Windows 10 to fast ring testers containing quite a number of changes, including work on the operating system’s do-not-disturb feature, and further tinkering with the Edge browser.

Build 17074 beefs up the Quiet Hours feature which, when turned on, prevents the user from being interrupted because they’re busy working hard (or perhaps gaming hard), only allowing notifications to come through from ‘important’ contacts or apps (and blocking the rest).

With the new preview build, you can set your own schedule for when Quiet Hours kicks in – and customize the relevant priority list to make sure notifications from important sources always get through.

Quiet Hours also engages automatically when you are playing a full-screen game, or when you’re duplicating your display (so that you won’t be interrupted during a presentation). These are certainly nifty added touches.

Edging forward

Microsoft has made another bunch of improvements to the Edge browser, including an overhauled Hub view that displays more content, and is more intuitive to use.

Edge has also got the ability to save and auto-fill credit (or debit) card details on website payment forms, with Microsoft noting that card information is securely saved (if you request the browser to do so). Also, the CVV security number on the rear of the card is never saved.

Furthermore, reading ebooks in Edge – as well as PDF files and web pages in Reading View – has been much improved with new Fluent Design elements introduced to improve aesthetics and generally streamline the experience. It’s now possible to enjoy ebooks or Reading View pages in full-screen, too.

Microsoft also modified the Start menu to show links to the Documents and Pictures folders by default.

Nearly-there-share

The Near Share feature that allows you to easily wirelessly share files between PCs in close proximity – it’s basically Microsoft’s take on Apple’s AirDrop – has also been worked upon to make it more reliable. If you found this feature too flaky before, Microsoft is urging you to try it again in this new build.

There are a ton of other tweaks and adjustments in Build 17074 of Windows 10, like the ability to write with a stylus directly into a text field in the UI, so you can scribble straight into a search bar (which is enlarged when you tap on it with your pen to make writing inside it easier – as some of those interface bars can be pretty small).

For the full exhaustive rundown of changes, along with potential issues affecting this build, see Microsoft’s blog post.

Speaking of issues, note that this preview build has been blocked for PCs running older AMD processors. This is because it contains some further tweaks in terms of defending against Meltdown and Spectre, and the patches against these critical bugs have been known to cause boot failure in some machines running older AMD chips.

      

Best laptops of CES 2018

CES 2018 has shown off some amazing laptops coming out this year, and we got a chance to get a close look at many of them at 2018’s event.

We’ve seen incredibly thin and light laptops, powerful gaming laptops that would make some desktop PCs envious, and a new breed of laptop that can last almost an entire day on a battery.

The best laptops of CES 2018 highlight just what the humble laptop form factor is capable of, as in a show that was brimming with drones, wearables and robots, it proved that laptops are still vital devices that can seriously impress us. Read on for our pick of the best laptops of CES 2018.

The Lenovo Miix 630 impressed us so much we awarded it our best laptop of CES 2018. As the name suggests, this is a mix of devices, being both a Windows tablet and also a laptop. Thankfully, there’s none of the compromises here that other hybrid laptop/tablets often suffer from.

It has a sharp 12.3-inch touchscreen with a 1,920 x 1,280 resolution, and it’s protected by Corning Gorilla Glass and a keyboard cover that’s comfortable to type on. The Qualcomm Snapdragon 835 system-on-a-chip processor with Adreno 540 graphics powers the Lenovo Miix 630, giving it enough grunt for pretty much any day-to-day task, while also promising some seriously impressive battery life.

If the Lenovo Miix 630 is representative of what this new breed of Snapdragon-powered laptops will be like, then we’re very excited for what the future holds.

The MSI GE63 Raider RGB Edition is another award winner, bagging our Best Gaming Laptop award at this year’s CES 2018. It’s an impressive gaming laptop – inside and out. It features RGB lighting that can sometimes look a little garish, but here it works brilliantly, turning the MSI GE63 Raider RGB Edition into an eye-catching device that really stands out from the crowd.

It’s not all about the looks, either, and the MSI GE63 Raider RGB Edition promises to be a powerful gaming laptop that can run the latest games in all their graphical glory. We can’t wait to get our hands on one and give it a proper test soon.

At CES 2018 Acer showed off some wonderful laptops, including an overhauled Swift 7. The previous Swift 7 model was already impressively thin and light, but Acer has managed to make it even thinner – from just over 10mm to an exceptionally trim 8.98mm, while increasing the Full HD display size from 13.3-inch to 14-inch.

Acer has also added built-in 4G LTE connectivity to the notebook, so you can connect to mobile data services, rather than relying on Wi-Fi. By combining a slimmer and lighter design with even more features, the Acer Swift 7 is easily one of the best laptops at CES 2018.

As we expected, Asus also had a strong laptop showing at CES 2018, and the device that really impressed us was the Asus ZenBook 13. This well-designed ultrabook has an all-metal design and weighs just 985g, with Asus claiming it will be the ‘ultimate’ in portability.

We’ve always loved Asus’ ZenBook machines so we’re looking forward to seeing just how good the new Asus ZenBook 13 is when it launches in the first half of this year.

LG announced a new line of LG gram laptops at CES 2018 which promise an either lighter laptop experience, with the 13.3-inch weighing just 961g. Even with the reduced weight and size, LG has still managed to add a second solid state drive for additional speedy storage.

Even though it’s thin and light, it doesn’t mean the laptops are fragile: as LG has ensured they pass seven MIL-STD 810G durability tests for impact, temperature and pressure resistance thanks to their new nano-carbon magnesium shell.

There will also be a suite of optional upgrades available as well, so customers can customise their laptops to suit their needs.

The Dell XPS 13 has been sitting pretty atop our list of the best laptops for quite a while now, and having seen the latest version of the Dell XPS 13 at CES 2018, it looks like it’s not going to lose its top spot any time soon.

With a display that now goes up to UHD 4K on some models, as well as tweaks to the design to further refine the laptop, the best laptop in the world just got a whole lot better. The chassis is now 30% thinner, and it’s a touch lighter to carry as well. The improved keyboard is another highlight, and overall it makes the Dell XPS 13 one of the best laptops we’ve seen this year at CES.
