The best photo-editing apps for Android and iOS

Jay Wennington/Unsplash

Applying layered edits and robust filters to digital photographs was once limited to desktop devices. Now, you can not only capture high-resolution (and RAW) photos on your phone, but also edit them directly on your mobile device, making them ready to be shared on whatever social networks you rely on to keep your friends and family up to date.

On both Google’s Play Store and Apple’s iOS App Store, there is no shortage of photo editing apps to choose from. While we have specific guides for the best photo apps for both Android and iOS, we’ve also wrapped up the best photo editing tools available on both platforms. So, whether you’re switching from one to the other and want options or simply want to future-proof your workflow should you switch down the road, we’ve got you covered.

Adobe Lightroom (Free, $10/month subscription option)

Adobe Lightroom has become the gold standard for digital photo management and editing amongst professionals. Thankfully, due to the simplified interface and wonderful syncing features, it doesn’t take a pro to either manage or edit photos in the cloud-based version, Lightroom CC. Available on both Android and iOS, Adobe Lightroom CC is a full-featured photo manager and editor, complete with RAW photo support, presets, exposure adjustments, watermarking, and so much more. It’s free to download and edit photos in, but if you want the ability to sync your photos across devices and use the premium features, you’ll need to shell out for Adobe’s Photography Creative Cloud plan, which costs $10 per month and also gives you access to Photoshop and Lightroom Classic.

Photoshop Express (Free)

Speaking of professional-grade photography tools, there’s perhaps no tool that is more synonymous with photo editing than Adobe Photoshop. Adobe released an Express version a while back, which, while not as powerful as its desktop counterpart, still lets you crop photos, adjust exposures, and carry out a variety of tasks. You can even create your own presets, which can be a huge time saver when editing photos on your phone or tablet.

Snapseed (Free)

Snapseed is a professional-grade photo editing app designed by Google. It features a massive amount of editing options to help even the most mundane photos jump to life. Snapseed gives you control over your images by including a host of sliders capable of altering a photo’s vignette, blur, temperature, and other attributes, including grainy overlays, 1960s-style film reel effects, or its unique Retrolux filter. You can even stack effects on photos, similar to Layers in Photoshop, making it easy to produce a brand-new result each time you edit a photo.

VSCO (Free with optional in-app purchases)

VSCO — pronounced viz-co — is a photo editing app designed around the idea of making your smartphone photos look more like film. In addition to a set of included filters, VSCO also lets you purchase packs of presets, each of which has their own aesthetic for particular types of images. VSCO also features a built-in community that includes both professional and amateur artists and photographers who share their naturalistic photography with each other. With professional-grade tools and advanced camera controls, VSCO is a great app for novices and professionals alike.

Afterlight ($3)

Its developers call it “the most powerful, full-featured photo editing experience on mobile.” While that might be a bit hyperbolic, it’s not that far from the truth. Afterlight has all of the basic photo editing tools you’ll need, as well as built-in filters, frames, and RAW support on both Android and iOS. Like other apps, you can even create your own filters to give your photos a distinct look time and time again. The best part is, it’s a one-time purchase — no need to spend more on in-app purchases to unlock more features.

Download now for:

iOS Android

Lens Distortions (Free with an optional in-app subscription purchase)

Known for its impressive plugins and apps for desktop devices, Lens Distortions has also created a mobile app for both Android and iOS that brings its distinct editing suite to your mobile devices. Whether it’s a color filter you’re looking for or an overlay effect such as a light leak or flare, Lens Distortion has a slew of realistic effects you can add to your photos. Lens Distortions is free to download on both Android and iOS and includes five free filters in each section with the free version. If you want access to all 250 premium filters, you’ll have to shell out a dollar per month.

Android iOS

Who knew that you needed at least six apps to make your photos look good? Well, okay, maybe you don’t need all of them. But it is a good idea to experiment with different apps and find the one that works best for your style. With any of these in your holster, you’ll be on your way to racking up the likes and comments you need in order to be a champion of Instagram. Go ahead, download them and achieve some social media immortality — or at least a ‘like’ from your grandmother.

HTC Vive review

Research Center:

HTC Vive

The Oculus Rift VR headset was first, but it was largely designed for seated or stationary use, which means it’s at its best only in certain specific genres, such as cockpit games. The HTC Vive, it’s primary competitor, is meant to be used in a room, while standing or walking (though it can also be used sitting). Upon its release, it’s a design decision that instantly makes it feel more immersive, creating a Star Trek holodeck-like space in your room to virtually walk around in.

The headset itself packs in a pair of OLED displays with 2,160 x 1,200 pixels of total resolution. The Vive also includes not one, but two tracking stations, and a pair of motion controllers with IR tracking. Also important is the 720p camera on the front, for object tracking and pass-through, which we’ll explain more about later.

The HTC Vive has been reduced down to $500 on its own, as long as you have a system that can handle it, of course. At its new value price, can it compete with newer headsets like higher-resolution Vive Pro or the stand-alone Oculus Go?

Sturdy, sleek

The Vive looks like a device pulled straight out of the future. The infrared tracking dots that appear across the face of the headset are indented from the rounded shape of the headset, creating a distinct, and more aggressive, look from the Oculus Rift and other VR headsets, which are more elegant and streamlined. Personally, we find the Vive attractive, at least in the sense that it looks as futuristic as virtual reality feels.

It helps that every piece of the kit, from the trackers, to the controllers, to the cables and the link box, is built from sturdy, thick plastic. It does mean the headset itself is pretty heavy, but as we’ll see, balancing weight properly is more important than shedding pounds.

The controllers are unique. While the closest resemblance might be to a Nintendo Wii Remote, even that feels forced. Their interesting shape is often replicated visually in-game, and the odd ring at the top becomes the perfect place to house gems, or grab objects.

Unfortunately, serious construction and solid connectivity comes at a price, and that price is the Vive’s cable. It’s thick and can be a little unwieldy, especially in games with a lot of spinning or moving around. You’ll get used to it after a while, but it isn’t the most elegant solution. We’re always a little afraid of tripping over your cord.

The cables run into a link box instead of straight into the computer. That makes it easy to run all the cables, power, USB, and HDMI, to the same place, without having a separate power cable. It also acts as a breakaway in case you get a little too enthusiastic, preventing you from yanking an expensive gaming PC off its desk.

Comfort comes first

The Vive’s headband has improved drastically from the Vive Pre’s attachment mechanism. The bands on both the sides and top are much sturdier and thicker. The Velcro has side tabs to help adjust the fit while the headset is on, and most people find a comfortable fit in less than a minute.

This is the VR experience you’ve always dreamed of.

It helps that the face gasket on the headset itself is quite squishy, and goes all the way around your eyes, with a short break at the bottom for the rubber nose rest. Once it’s fit right, there’s no pressure points around the outside of the headset, which thankfully means no “VR face,” an issue with some headsets that leaves a red ring around your eyes.

That hasn’t stopped us from sweating into the Vive on a number of occasions. Especially in games like Hover Junkers, that involve a lot of jumping around and ducking, the foam frame turns into a bit of a sweatband. It’s not dripping, but it’s enough to make you think twice about handing over the headset to someone else after an intense session.

Virtual reality that won’t make your hurl

We invited a handful of Digital Trends employees to test out the Vive for brief demos, to identify any nausea-inducing problems with the headset. Reactions were so positive we had to drag people screaming out of the virtual world. From The Lab to Hover Junkers, all our test subjects wanted to do was play more, check out the other games, and come back around for seconds. Only a couple of our testers reported headset-releated comfort issues, which were mostly solved with headband tweaking.

All testers reported high levels of immersion, and a common high note was the precise, intuitive nature of the controls. Nausea was missing in action, even among individuals normally prone to motion sickness. Letting the user Vive move in real space while also moving in virtual space, as the Vive allows, seems to dramatically improve long-term comfort relative to a seated headset.

A few games available on SteamVR, like 4089: The Ghost Within did give us nausea. This game, and others that only work with a standard Xbox controller, exhibit many of the limitations of the Oculus Rift (and its dev kit predecessors). You have to sit down and the head tracking is slow.

The biggest problem with the Vive might be how much activity it does require. A few of our testers reported that using the headset was “a lot of work,” in the sense moving around to play a game is a lot less relaxing than plopping down on a couch. The Vive, though immersive, may not be the device you’ll turn to after a long, tiresome day at work.

There are also some accessories you could invest in, which use HTC’s Vive Tracker hardware, but we spent some time with them and you’re probably better off sticking with the included touch-controllers.

A beautiful display from a narrow perspective

Before we get too technical about the details of the Vive’s display, I want to point out that every head-mounted display (HMD) I’ve tried to this point has had some amount of what’s referred to as the “screen door effect.” No matter how high resolution screens get, it’s not too tough to see the individual pixels when it’s just an inch or two from your eyes.

The upshot is that as long as the processing, UI, and tracking are sharp enough, the screen door isn’t too distracting. I’ve also found that after a few minutes of playing a game, the immersion is enough to stop your eyes from looking for it. It also helps when games adapt their aesthetic to this sort of effect. Resolution issues are most clearly visible on distinct edges, especially on cartoon characters. Higher definition textures, landscapes, and flat surfaces especially look quite a bit sharper.

Our main complaint about the Vive’s display is not the screen door effect itself, but rather the edges of the display, and the rings around the field of view. When the edges of your vision are dark, the supporting structure blends in. When the screen is brightly lit, it’s like wearing a pair of sunglasses with big, dark frames. It’s not detrimental to the experience, but in quiet moments it can definitely downgrade the sense of immersion.

The Vive includes a pair of basic earbuds, although we have a feeling most of you will prefer your own headphones. Even over-ear headphones fit comfortably with the headset on, and there’s a 3.5mm plug on the back so your headphone cable doesn’t have to reach from the link box.

The virtual reality you’ve always dreamed of

All of these elements don’t mean much if they don’t come together to form a cohesive, engaging experience. Thankfully, they do. Being able to move around, even in a small space, is a huge boon to realism. Even after several hours of play, we found ourselves reaching out to touch a fish swimming past in TheBlu, or ducking quickly behind cover in Hover Junkers.

That freedom of movement also helps keep the virtual world engaging when you might not want to be a part of it. Survival horror games force you to face your fears, even as you cower in the corner of the usable space. When a humongous jellyfish floats toward you, you can’t help but step out of its way.

Add in online play, and things only grow more enthralling. Hover Junkers places you as the driver and defender of your own hovercraft in a deserted wasteland. Hiding behind junk you dug out of the ground while firing off shots at a real opponent is immediately gratifying, even more so when you show them a rude gesture as their ship explodes into pieces.

Part of the draw with the HTC Vive is, of course, the Steam marketplace. Not only are there a wealth of games ready to play, or coming soon, that support room-scale virtual reality, but veteran PC gamers may already have games in their library that support the headset.

Surprisingly robust software

The Rift is no slouch when it comes to ease-of-use and the overall user experience. Indeed, that was a primary focus of Oculus as it developed its headset. But the Vive is no slouch, either, which is a bit surprising given that it’s a joint expedition by two companies, rather than a product built under a single umbrella.

The headset and controllers are built from sturdy plastic that’s pleasing to touch.

Setting up the device means following a process outlined by Valve. While there’s no shortage of cords to connect, and positioning the lighthouse sensors that detect your position in the room can be a pain (they must be at least 4-5 feet high, or higher, and ideally tilted slightly towards the ground), the technical understanding requires is minimal. There’s just a few buttons to press, and connectivity issues were rare, despite the fact both the lighthouses and the controllers communication wirelessly.

You can launch into VR either through the Steam desktop software by starting a VR-compatible game, or by launching SteamVR, which opens a front end that’s very similar to Steam’s Big Picture mode. It’s not as attractive as Oculus’ comparable home screen, but it operates similarly, and we found it reasonably intuitive.

The Vive is not a plug-and-play device. Some level of understanding is required. But if you’ve ever hooked up and mapped a PC joystick, connected a wireless printer, or installed a piece of PC hardware, you should find the Vive’s setup a cinch.

Warranty

HTC includes a one year limited warranty. That’s the standard offering, even for high-end gaming peripherals. The Oculus Rift also offers a one-year warranty.

Our take

You’ll need three things to experience what the Vive has to offer: A VR-ready computer with a very nice graphics card, enough space for room-scale experiences, and $500. With that,

Is there a better alternative?

Not yet. The Vive Pro is certainly a better headset, but we didn’t find that the experience justified its cost.

For now, the HTC Vive and Oculus Rift are pretty evenly matched. We like the Vive better, but the Oculus Rift does come in at just $400, which leaves you some extra money for PC upgrades or new games. It’s an appealing alternative that is almost as good as the HTC Vive, even if it isn’t quite as capable at room-scale experiences.

How long will it last?

Physically, the HTC Vive is a robust headset, the one here in the office has survived ever since launch without so much as a scuff or a broken cable. It might not wear out any time soon, but it will start showing its age pretty quickly as new headsets hit the market.

Should you buy it?

Yes. Even if you’re not into VR, or have no interest, you at least need to try the Vive. This is the VR experience you’ve always dreamed of. It’s the closest thing we’ll get to The Matrix anytime soon.

Revisit the good old days with the NES Classic Mini, now in stock at Amazon

You should hurry up.

Update: The NES Classic Controller is now available for only $9.98 at Amazon. That’s its regular price, though it’s hardly ever in stock and more often sold for nearly $25 by resellers. Make sure to grab one, and the console which comes back in stock on August 1st, while you have the opportunity.

Ah, Nintendo, breaker of hearts and crusher of dreams. How can one company be so good at releasing such limited quantities of the coolest items ever?!

The Nintendo NES Classic Mini has been hard to nab from the get-go. When it was first released, people waited in line for hours in the hopes of snatching one up — myself included. This little gadget hit the reseller market fast after stock was depleted, selling for up to $1,000. Seriously. It was once thought to be gone forever, and it left thousands of fans upset, knowing that they may never have the chance to revisit their childhood favorites on an actual Nintendo machine. (Yes, you can emulate retro games. No, it isn’t the same. Don’t @ me.)

Thankfully, you don’t have to wait for six hours in the freezing Wisconsin snow to get yours like I did. You don’t even have to leave your house. Amazon has the Nintendo NES Classic Mini console in stock for the MSRP of $59.99. No markups, no hassle, and no blood, sweat, or tears. Except for maybe tears of joy.

This thing is awesome. It has the look and feel of the original console, although it is slightly smaller and sleeker. It includes an old-school controller and it’s packed with 30 games, including Super Marios Bros., Donkey Kong, The Legend of Zelda, Mega Man, and more. It’s worth noting that the controller cord is pretty short, but extenders are available for cheap or you could even pre-order a wireless controller. If you were inclined to do some web searching, you may also find that rumor has it you can hack the console to include hundreds of other games, although you run the risk of bricking your machine, among other things, and an editor such as myself couldn’t possibly suggest that you do such a thing.

This is the first major restock of this console since it was released. If you’re interested, trust me: there are thousands of other interested people, too. Hop to it and beat them to the punch before it sells out again.

Google bets on blockchain technology with two new Google Cloud partnerships

Google now supports distributed ledger technology, aka blockchain, on the Google Cloud Platform. The reveal arrives by way of the company’s announcement regarding the Google Cloud Next ’18 conference in San Francisco starting Tuesday, July 24. Google will have a 50-minute session called “Distributed Ledger Technology Partnerships on Google Cloud” talking about Google’s partners and how to develop blockchain-based solutions.

“Customers can now explore ways they might use distributed ledger technology (DLT) frameworks on GCP with launch partners including Digital Asset and BlockApps, and try open-source integrations for Hyperledger Fabric and Ethereum later this year in our GCP Marketplace,” the company says.

For the uninitiated, a distributed ledger, or blockchain, is a decentralized database shared and maintained by connected computers across the globe. Each transaction can be publicly read while securely stored using cryptography. These transactions cannot be altered without modifying the entire chain because the cryptographic key of one transaction is stored in the next transaction.

Blockchain technology is highly associated with cryptocurrencies, but companies such as Google and Microsoft are examining how their services would benefit from the maturing technology. According to a report by CBInsights, Google was the second-most active blockchain investor between 2012 and 2017, falling between SBI Holdings and Overstock.com. Others include CITI and Goldman Sachs.

Along with Google, Digital Asset revealed its plans for the Google Cloud Platform, announcing that both its blockchain platform and developer toolset are now offered through Google’s cloud. Developers can now build, test and deploy solutions on-demand based on Digital Asset’s blockchain without any need to make manual configurations.

“We’re partnering with Google Cloud to provide developers with a full stack solution so they can unleash the potential for web-paced innovation in blockchain,” Blythe Masters, CEO of Digital Asset, said in a statement. “This will reduce the technical barriers to DLT application development by delivering our advanced distributed ledger platform and modeling language to Google Cloud.”

Google will also provide a preview of the Digital Asset Modeling Language (DAML) toolkit for building blockchain-based applications. Google is one of the select few technology partners chosen to participate in Digital Asset’s limited beta for the DAML kit preview. The DAML Platform-as-a-service will also be provided on the Google Cloud Platform.

BlockApps made a stand-alone announcement as well, announcing that its BlockApps STRATO Blockchain-as-a-Service platform for enterprise will be made available on the Google Cloud Platform. The company described Google’s entrance into the blockchain field as a “landmark event.”

“Based on the Ethereum protocol, BlockApps STRATO provides enterprise-grade API integration capabilities, configurable consensus algorithms, and the capability to query and report on blockchain data using a traditional SQL database,” BlockApps says. “Application developers will find STRATO familiar, easy to use, and easy to integrate with existing enterprise systems.”

Unnamed sources said in March that Google is working on its own blockchain technology that third parties can use to post and verify transactions. Google will supposedly provide a “white version” of this technology as well that companies can run locally on their own servers rather than through Google’s cloud.

NASA’s invention of the year award goes to … space lube?

NASA’s Inventions and Contributions Board handed out its award for the 2018 Government and Commercial Invention of the Year, and the winner is … space lube. Before your mind descends into the gutter, we should note that the material in question is intended for industrial purposes. The fourth-generation material NASA has developed in this area, it’s a solid coating that is able to continue lubricating in temperatures that range from negative-300 degrees to 1,700 degrees Fahrenheit. Not only is it superior to boring old lubricants like oil and grease, but it’s also better than solid alternatives like graphite or other carbon-based materials.

“PS/PM400 is a solid lubricant material that reduces friction and wear in sliding contacts in a similar fashion to graphite and Teflon, [but at significantly more extreme temperatures,]” Christopher DellaCorte, the NASA’s senior technologist behind the invention, told Digital Trends. “Conventional oils, greases, and solid lubricants begin to break down much above about 600 degrees Fahrenheit. This ‘bump’ in temperature capability opens up the design space for machines and mechanisms to place moving parts right inside the hottest environments, like on the surface of Venus or deep inside aircraft engines, without the expense or problems affiliated with providing active cooling.”

In addition to the possibility of being used in rocket engines and aircraft turbines, NASA’s PS/PM400 has also been licensed to ADMA and Hohman Plating, two companies working in the automotive industry to develop exhaust system parts and gas recirculation valves. Space lube may additionally find a home in a wide range of other industries, such as with drone makers, large equipment manufacturers, and even in heat treatment furnace conveyor systems, where the material could allow even higher temperature operation, at lower cost, than its predecessor. (And before you ask, no, NASA’s space lube is highly unlikely to find its way onto the set of any of those attention-grabbing zero-gravity porno flicks any time soon!)

“I won’t lie; awards and recognition are always welcome career mileposts,” DellaCorte continued. “They signify that one’s organization values and appreciates the work. However, the real benefit of such an award is the more effective dissemination of the technology so it can be more rapidly deployed into more applications saving time, money and making products more efficient.”

With Dropit’s delivery service, you can literally shop till you drop

Andy Boxall/Digital Trends

Imagine the end of a long day of shopping. You’re left with several bags of all shapes and sizes from various stores, they’re heavy, you don’t have a car, and you’re slowly realizing you will need to carry all of this home. It’s a burden most shoppers are familiar with, particularly those in urban areas.

But a new service called Dropit is promising to relieve that part of the shopping experience. It takes the best part of retail store shopping — seeing and feeling items in person — and adds in a distinct benefit of online shopping: Not having to carry anything home. We recently had a demonstration of Dropit’s service in London, and a company representative told us the service will launch in the U.S. later this year. Here’s how it works.

No more bags to carry

The concept is simple. You buy stuff from participating stores, leave it all at a special location in those stores, and by the next day it will all be dropped off at your house. There is a delivery charge involved, but it’s a reasonable 10 British pounds, or about $13 at current conversion rates — that’s for as many bags as you can fill during the day. At the moment, before Dropit comes to the U.S., it’s available in the West End of London. That’s where we tried the service out.

Dropit is controlled through an app on your phone, which means it needs to be well-designed, simple, and reliable. It’s available for Android and iOS, and we tried it out on an iPhone X. Once you’ve shopped in a store, the app prompts you to start the drop-off process, which you’d do at the checkout. Pictures of receipts are taken, providing a record of everything being delivered for all involved. Once this is done, your items are secured inside a special Dropit bag, and the barcode is scanned in the app.

The Dropit app is fast and smooth, and the instructions are simple to follow.

From here you can either end the Dropit session and a delivery driver will pick your items up later on, or you can leave it open and keep on shopping. This is a considerable benefit, as you don’t have to shop at just one store or pay multiple delivery charges. It’s a single session, at as many participating shops as you can cram in.

Once your credit card has had enough, you end the shopping day in the Dropit app, and it’s sent out for the delivery team’s attention.

Depending on the time of day you complete your Dropit delivery request, it’s possible everything will be delivered on the same day, minimizing the wait time completely. Otherwise, if you’re too late for same day delivery, your items will arrive the day after. We dropped off our products at around 5 p.m., so our delivery was scheduled for the next day between 7 a.m. and 10 p.m.

Convenient

The app is fast and smooth, and the instructions are simple to follow. It requires basic personal information and a payment method to get started. Unfortunately it doesn’t accept Apple Pay, but the Dropit app will take a scan of your card to save you the hassle of entering all the information.

Andy Boxall/Digital Trends

The drop-off points are usually in the partner store at checkout, and staff don’t need to do anything except bag up the products and hand it over to the deliver driver later on. Everything is booked through the app. Our bag contained a variety of items, from toys to toiletries, and Dropit will take most things aside from anything breakable.

For same day delivery, the delivery distance is limited to the greater London area. For next day delivery, you can get your items delivered anywhere in the U.K. They’re also happy to send your goods to a hotel or an office, increasing convenience for travelers too. Our delivery point was outside London, and the Dropit delivery driver arrived before 8 a.m. the day after.

The app sent notifications before and after delivery — although the delivered notification was several hours late — and it’s also possible to track your order in the app.

Anyone traveling into the city to shop should try this service out.

Sadly, this didn’t include location data, only that the package was on the way. As you’d expect, everything was in perfect order and the bag was still completely sealed. It’s also seemingly impossible to break it open and reseal it, giving us peace of mind about security, and we resorted to scissors to get inside.

We were impressed by the simplicity and speed provided by Dropit. Anyone traveling into the city to shop — residents or tourists — should definitely try the service out. Tourists stand to really benefit from not having to carry around bags if an impromptu shopping break interrupts a day of sightseeing. Dropit’s partner stores include Uniqlo, New Balance, Gap, Topshop, Urban Outfitters, French Connection, Adidas, and M&S. You can find a full list here.

Dropit is a free app download for iOS and Android, and although plans for a U.S. launch are in place, we don’t know details of when it will occur, or in which cities the service will be available.

Microsoft provides free lessons for quantum computing basics

Steven Winkelman/Digital Trends

Want to learn more about quantum computing and how to program in the Q# language? Microsoft just launched Quantum Katas, an open source project that does just that by providing you with tutorials for learning at your own pace. According to Microsoft, these exercises are based on three learning principles: Active learning, incremental complexity growth, and feedback.

“Each kata offers a sequence of tasks on a certain quantum computing topic, progressing from simple to challenging,” Microsoft Quantum Team states. “Each task requires you to fill in some code; the first task might require just one line, and the last one might require a sizable fragment of code. A testing framework validates your solutions, providing real-time feedback.”

Currently, there are only four katas covering basic quantum computing gates, superposition, measurements, and the Deutsch-Jozsa algorithm. Each kata is a stand-alone project containing a sequence of tasks progressing from trivial to challenging, requiring you to manually insert chunks of code. They also provide a testing framework that sets up, runs and validates your final code.

For instance, the first kata covers computing gates, another term for basic operations, used in quantum computing along with the concept of adjoint and controlled gate versions. Those provided in the kata belong to the Microsoft.Quantum.Primitive namespace, the notes reveal.

To use these katas, you need to install the Quantum Development Kit for Windows 10, MacOS and Linux. This kit is typically used to build your own quantum computing programs and experiments. It includes the Q# language and compiler, the Q# standard library, a local quantum machine simulator, a quantum computer trace simulator, and two other components. After installing the kit, you can grab the katas through Git or by downloading stand-alone copies in a ZIP file.

Microsoft says you shouldn’t panic when all tests initially fail after opening a kata. You need to jump into the Tasks.qs file and manually enter code to complete all tasks. These tasks are covered by a unit test that requires you to insert the correct code, rebuild the project, and then re-run the related tests. If you did everything correctly, the corresponding unit task will pass and you can move on to the next stage.

Microsoft’s katas arrive after the company hosted its first Q# coding contest in early July, challenging more than 650 developers and new programmers alike. According to Microsoft, more than 350 participants solved at least one Q# problem while 100 participants solved all 15. The problems ranged from generating a superposition of all basis states to creating a second array reconstruction algorithm. The contest winner completed all tasks under 2.5 hours, Microsoft says.

Given Microsoft’s Quantum Katas is an open-source project, the company welcomes all contributions and suggestions. “Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that you have the right to, and actually do, grant us the rights to use your contribution,” Microsoft adds.

5 features we want in Google’s Pixelbook 2

Thanks to its clean design and powerful internals, Google’s Pixelbook remains one of the best Chromebooks on the market today and a capable laptop replacement. However, it’s been almost a year since the Pixelbook went on sale, and rumor is ripe that Google will announce a Pixelbook successor later this year with updated internals.

Even though we liked the first-generation Pixelbook, there are a number of upgrades that would help the Pixelbook 2 stay competitive against Apple’s recently refreshed MacBook Pro, Microsoft’s newly announced Surface Go tablet, and a slate of Windows 10 convertibles, detachables, and laptops. Here are five features we’d love to see Google adopt on the Pixelbook 2:

Dell was one of the first PC companies to experiment with barely-there bezels on its XPS laptop, and the feature has proven to be so popular that other notebook manufacturers followed suit. Even if Google recycled the current current aluminum-clad design with glass accent on the current Pixelbook for its second-generation laptop, thinner bezels would not only help the laptop appear more modern against competitors, but it’s a feature that also brings business appeal. A design with slimmer bezels would help the Pixelbook 2 occupy a smaller footprint on a desk or a laptop bag.

The coveted feature is now all but officially confirmed. VentureBeat reporter Evan Blass recently tweeted that smaller bezels is part of this year’s upgrade, and given his previous record with providing reliable leaks, the feature appears highly likely. Smaller bezels coupled with a modern design, a high resolution touchscreen display, and improved pen support would make the screen on the Pixelbook 2 a big winner.

Updated processors

When it launched in late-2017, the original Pixelbook shared the same 7th-generation Intel mobile processors as Apple’s MacBook Pro, making it a capable machine, especially for a Chromebook. However, with most laptop manufacturers (including Apple) recently making the switch to newer 8th-generation processors, we can likely expect that Google will make similar upgrades when it refreshes the premium Pixelbook. If this happens, the Pixelbook 2 could be the most powerful Chromebook ever made, topping out with a six-core Core i7 8th-generation Intel processor. 

Depending on the launch timing of the Pixelbook 2, Google’s switch to an 8th-generation processor may make for an awkward refresh this year. Intel is rumored to debut its 9th-generation CPU later this year as well, though it may take some time before laptops with the newest chipset to appear on store shelves. 

Improved tablet support

Chromebook partners have already begun experimenting with new form factors for Chrome OS. Though the Pixelbook brought the convertible form factor to the premium segment for Chrome OS, Acer has since debuted a Chromebook Tab 10 tablet and HP launched its Chromebook x2 with a detachable form factor, similar to Microsoft’s Surface Go.

Interestingly, source code discovered earlier this year by XDA-Developers suggest that Google is working on a new Chromebook with a 4K screen and a detachable form factor. While we doubt that applies to the new Pixelbook, Google needs to improve the tablet experience either way. On the software side, Google has been making subtle tweaks to make Chrome OS better for tablets, but there’s still a long way to go.

Alongside the bolder Material Design 2.0 refresh to modernize the aesthetics of the operating system, Chrome OS is also said to be borrowing heavily from its Android cousin, bringing larger buttons with rounded corners to better support touch. It’d be great to see Google launch some of these new interface tweaks with its new flagship device.

Stylus silo

Google brought stylus support to the first-generation Pixelbook, but the stylus seems more like an afterthought. Having a stylus silo or even magnetic attachment to stow the digital pen when not in use would show that Google is serious about the stylus. Samsung provides a stylus silo on its premium Chromebook models, while Lenovo offers a similar design for some of its premium pen-enabled ThinkPad convertibles. 

Currently, Google sells the Pixelbook Pen as an optional $99 add-on, and a $29 third-party leather sleeve with a magnetic clip provides similar functionality to Microsoft’s magnetic Surface Pen. If a stylus silo is built into the Pixelbook 2, Google may also bundle the stylus, making the pen feel more integrated into the Chromebook experience while saving users some money.

Integrated LTE

Having a built-in LTE modem on the Pixelbook 2 is much more than just about convenience. With better Android support on Chrome OS devices, and the operating system’s potential to supplant and replace Android tablets, having always-on connectivity would be a huge advantage. This is the same vision that rival Microsoft has for its Always Connected PC platform.

The feature wouldn’t be too hard for Google to do, given that it already runs its own virtual mobile network through Project Fi, which relies on T-Mobile’s and Sprint’s network infrastructure for the backbone. Google’s experiment to deliver voice and mobile data service on its Android smartphone hardware has been met with positive reviews. Google could potentially apply a similar business model to take on data-only devices, like Chromebooks and Chrome OS-powered tablet.

Even though LTE on laptops is uncommon in the US outside of business-class notebooks, it’s still a coveted feature that’s starting to grow in popularity. Microsoft’s Surface Pro, a Windows-powered tablet that’s positioned for premium consumers and business users, comes with an LTE option, and recently Microsoft partnered with Sprint to deliver free data access to the Always Connected PC platform. If it wants to compete with the Surface Pro or iPad Pro, it’s a must.

Need a new laptop? We’re giving away a Dell XPS 13 compact laptop PC

In the past, if you wanted a slim and super-light laptop, your best choice was to stick with something like a MacBook Air. Slimline laptop PCs generally lagged well behind Apple’s offerings, and unless you wanted to deal with one of those goofy little 11-inch netbooks that were a nightmare to type on, your Windows options were fairly limited.

But Apple hasn’t held this edge against other laptops in recent years as MacBook innovations seem to have slowed while PC makers keep upping their game in big ways. Dell, in particular, has hit a home run with its fantastic XPS series, and we’re giving our readers a chance to score one for themselves, with one grand-prize winner taking home a brand-new Dell XPS 13 Windows 10 laptop.

Compact laptops can sometimes be hit-or-miss. This smaller form factor is hard to pull off properly, and these designs have to strike a careful balance between laptop functionality and tablet-like convenience without sacrificing portability or hardware capability. Start packing in too much beefy hardware and the computer will end up being too bulky and heavy, but make it too small and light and it won’t be powerful enough to perform well.

Dell has successfully threaded this needle with the XPS 13, which our review team named the best 13-inch laptop you can buy and the best laptop of 2018. Under the hood, this super-light compact computer punches well above its weight class with an 8th-generation Intel Core i7 CPU, a beefy 16GB of RAM, and a generous and snappy 512GB solid state drive. It comes loaded out of the box with Windows 10 as well.

Just as impressive, especially for a laptop of this size, is its crisp 4K display. The 13-inch screen boasts an Ultra HD resolution of 3,840 x 2,160, something that was unheard of for displays this small until very recently. The internal battery on the 4K also provides about 10 hours of juice when running under constant load, so you’ve got more than enough in the tank for a day’s work before needing to recharge.

Android distribution numbers: Everything you need to know!

Your (usually) monthly fix on the current state of Android.

About once a month, Google releases distribution numbers that outline the various Android versions and the percentage of current devices they’re running on. This data is meant for developers so they can create and update their apps according to which Android versions are the most popular, but they also give enthusiasts like us a glimpse into how quickly OEMs are adopting the latest and greatest the platform has to offer.

To source this data, Google tracks the Android versions of any devices accessing the Play Store over the course of a 7-day period. This ensures that only active Android gadgets are being accounted for and not your HTC Dream that’s been sitting untouched in a drawer for the past few years.

Any version that accounts for 0.1% or more is listed, but versions that have less than that are ignored.

Without further ado, here’s the current state of Android.

July 2018

It’s been a hot minute since we got our last batch of distribution numbers, but after skipping over June, Google’s back with an all-new set of data for July.

The biggest highlight for this month shows Android Oreo (8.0 and 8.1) now available on 12.1% of all devices — a huge step up from the 5.7% it saw just a couple months back. That’s still not a great adoption rate, but at least we’re getting somewhere.

The rest of the changes compared to May are as follows:

• Gingerbread — 0.1% decrease
• Ice Cream Sandwich — 0.1% decrease
• Jelly Bean — 0.7% decrease
• KitKat — 1.2% decrease
• Lollipop — 2% decrease
• Marshmallow — 2% decrease
• Nougat —0.3 decrease
• Oreo — 6.4% increase

May 2018

The data for May corresponds to Play Store activity for the seven-day period ending on May 7. Oreo has picked up another percentage point over the course of the month, and is at 5.7% overall — 4.9% being 8.0 and the other 0.8% for 8.1.

Nougat also saw a slight increase from 30.8% to 31.1%, followed by Marshmallow by 25.5%. Here’s the breakdown of how things changed:

• Gingerbread – No change
• Ice Cream Sandwich – No change
• Jelly Bean – 0.2% decrease
• KitKat – 0.2% decrease
• Lollipop – 0.5% decrease
• Marshmallow – 0.5% decrease
• Nougat – 0.3% increase
• Oreo – 1.1% increase

April 2018

For April of 2018, Google tracked Android devices accessing the Play Store for 7 days with the collection period ending on April 16.

The last report from February showed Oreo just barely accounting for more than 1% of Android devices, but that number has since climbed to 4.6% (4.1% being 8.0 and the other 0.5% going to 8.1). Nougat also sees an increase with a jump to 30.8% compared to 28.5% (7.1 and 7.0 combined), and Marshmallow is still trailing in second place at 26%.

Comparing these numbers to February’s findings:

• Gingerbread – No change
• Ice Cream Sandwich – No change
• Jelly Bean – 0.5% decrease
• KitKat – 1.5% decrease
• Lollipop – 1.7% decrease
• Marshmallow – 2.1% decrease
• Nougat – 2.3% increase
• Oreo – 3.5% increase

February 2018

February’s report was the first time Android Oreo crossed the 1% threshold despite that version of the OS being released back in August of last year.

Marshmallow continued with a tight grip at 28.1%, but this also marked the first time that Android Nougat jumped into first place with a combined total of 28.5% – that including versions 7.0 and 7.1.

Additionally, Ice Cream Sandwich (4.0.3 to 4.0.4) also finally dropped to 0.4% from last January’s 0.5%.

January 2018

In January 2018, Android Marshmallow still reigned supreme as the most popular version of the OS at 29.7%. This also saw 8.1 Oreo make an appearance on the board for the first time with 0.2% adoption, and 8.0 remained at the same 0.5% it was at in December.

Jellybean and KitKat both decreased compared to last month’s check-in, but Ice Cream Sandwich and Gingerbread are still holding on at the same 0.5% and 0.4%, respectively.
