Google has released blueprints for VR headsets made of cardboard and encouraged third parties to bring their best designs to market. Several are available for purchase with a "Works with Google Cardboard" badge, meaning they're compatible with Cardboard apps.

Users with some arts-and-crafts chops can create their own. The idea is simple, according to Clay Bavor, vice president of product management at Google. After constructing the simple cardboard headset, users simply slot their smartphones into the contraptions -- and voila: They get a VR experience for about US$20.
"Cardboard is about making it possible for anyone to check out virtual reality experiences with their smartphone," Bavor told TechNewsWorld. "Combined with the Cardboard SDKs, we want to make it possible for anyone to develop new VR apps or add to their existing apps."

Going Pro

A number of dedicated VR headsets have been priced around $400.
Oculus VR would like to offer its virtual reality headset and a gaming PC bundled for an "all-in" price of about US$1,500, which is meant to be a bargain.
Along with making a case to justify the equipment price tags, developers of VR hardware have been faced with the challenge of ensuring there's enough content to attract early adopters.

During I/O 2015, Google revealed how it intends to generate a trove of VR content for Cardboard and make money doing so.
Google has partnered with action camera manufacturer GoPro to develop Jump, a 16-camera rig that could put VR production well within reach of indie filmmakers.
"We thought it'd be good if someone who really knows how to build a great camera could help us out building our Jump 16-camera rigs," Bavor said. "So we called our friends at GoPro."
The 16 cameras function as one unit, allowing content creators to capture stereoscopic VR that delivers 360-degree videos with depth of field. The Jump rig's video resolution puts out about as many pixels as five 4K TVs, according to Google.
Google already owns a platform that may be perfect for the task of storing and streaming all of that video content -- YouTube. With its support for Jump videos, said to be coming soon, Google could see a bump in ad revenue.

Virtually Here

Virtual reality is coming, whatever the price. There will be 5-10 million VR headsets in the wild by next year, predicted Beck Besecker, CEO of Marxent.
While Google is offering the masses a taste of VR, a large number of consumers will want the very best of the tech, he told TechNewsWorld. Cardboard may offer an interesting use case for realtor showcases and other virtual tourism, but it may serve primarily to pique the desire for a better experience.
"I think [Cardboard] will help with the general popularity of VR," Besecker said, "but I think the folks that are really going to gravitate to VR are going to want a high-quality experience -- and gamers, specifically, won't mind paying for it."
It's long been held that gamers will drive the nascent market forward, but VR visionaries are looking to the second, third and fourth waves of virtual experience to capitalize on the technology's expansion.

Windows 10 is a well-meaning effort by Microsoft to mollify Windows 8 haters and coax Windows 7 loyalists to upgrade — all while stubbornly sticking to its goal of a single OS for every possible platform. And by framing the problem that way, Microsoft has given itself a nearly impossible task.
To the company’s credit, each new build lurches closer to being usable, although with new bugs every time, it is difficult to evaluate how smooth the final release version will be. Best case: It may earn the grudging acceptance of Windows 7 users who refuse to move to Windows 8. And part of that acceptance will come not from sudden enthusiasm for a new way of interacting with the desktop, but from a desire to take advantage of the clear core benefits Windows 10 provides in performance, security, administration, and memory usage over Windows 7 and even Windows 8.
So why is it so hard to convince users to move to a brand-new, free, feature-packed, more efficient OS? Apple does it all the time. Simply put, because Microsoft didn’t build Windows 8 or Windows 10 for Windows users. It built them to further its own business strategy of using the power of the once-ubiquitous Windows platform to extend its dominance into the rapidly growing mobile space. The result is an OS whose features are now flipping and flopping with each new build — as Microsoft tries to fix problems of its own creation.

Imagine how good a desktop OS Windows 10 could have been

What if instead, after realizing what a terrible mistake Windows 8 was, Microsoft had made the truly brave decision to come clean and change its strategy? If Windows 10 had been designed from the beginning to be the best possible desktop OS, and the thousands of developer years spent trying to make it everything to everyone were instead spent providing services and applications for the mobile OS platforms people actually want? If in tandem Microsoft was willing to let go of its sub-3% market share in mobile, it could also have spent the cash it used to buy Nokia to build out its cross-platform services offerings instead. We could have had a really excellent desktop OS — worth paying for — and great integration with the leading mobile platforms.
Certainly Microsoft has woken up to providing competitive versions of its applications on Android and iOS. But imagine how much further along it would have been if it had put real work into the effort starting years ago. Perhaps we wouldn’t have to use third-party utilities to sync our information between Google and Outlook, for example. Or OneNote might have supported syncing on Android during the first several years it was available, instead of only recently. Pick any Microsoft desktop technology you access from your iOS or Android device and you can come up with a list of features that would make it much more useful.

It’s not like there isn’t anything to fix in Windows

Anyone who thinks Microsoft didn’t focus on desktop users as it evolved Windows 8 and 10 because its desktop OS has “no need for improvement” hasn’t spent enough time wrestling with the inscrutable hex error codes from Windows Update, or debugging driver version mismatches, or finding information they’re sure is somewhere on their disk. While Windows 10 isn’t final, judging by the builds so far, all of those problems are still there. Even support for high-resolution displays is still spotty. Windows 10 adds some new Zoom options, but there is still no serious scalable-font solution that works across the full range of possible displays.
As a good example of how this alternate direction would have worked, let’s look at the Control Panel. No one doubts that it is an old, crufty system for managing a computer. A desktop-focused OS project would have overhauled it completely while preserving its functionality. Instead, Microsoft seems determined to replace it in bits and pieces with new “touch-friendly” settings that aren’t much more intuitive, and that become even more frustrating when you need to go back to the old system for pieces that are still missing. Windows 10 is supposed to address this problem, but we’re less than two months from shipment and Settings are still far from being either intuitive or finished.
Tablet mode and Continuum are also inventions seeking to solve a problem Microsoft has invented for itself. For the few of us who actually own and use a Surface Tablet mode, it’s sort of a good thing. (I love that I can both taken written notes and run Outlook on my SP3, but with the addition of desktop apps to Android, I’m not sure how many others will see the need to spend that kind of money for basic productivity.) It’s good because it is better than Windows 8, where often the touch keyboard wouldn’t pop up when needed, and icons could be hard to finger.
It’s still only sort of good, though, because it’s confusing and forces the user to have one more thing to think about. Somehow iPads and Android tablets seem to easily survive the addition of a keyboard without the need for an entire special OS mode. Like many of the other new features in Windows 10, it seems like a “throw it against the wall and hope it sticks” attempt to solve a user pain point — not a from-the-ground-up technology architected to support the broad range of devices that can now run Windows.

Windows 10 internals are actually pretty impressive

There is a lot to like about Windows 10 — in addition to having the best kernel Windows has ever had. Edge (aka Spartan) is promising (although it too is only a prototype version, and certainly could have been shipped separately). Cortana might be useful, but is so limited and buggy in the current builds that it is hard to tell. If it doesn’t get sorted out by July, Microsoft risks taking yet another step backwards in desktop search functionality, which would be a shame. Virtual desktops are a nice feature, although hardly groundbreaking.
The included apps are certainly way ahead of the ones Microsoft shipped with Windows 8, but Microsoft has had many excellent desktop apps over the years — including the now-dead Windows Media Center, LiveWriter, and MovieMaker. It is the company’s own fault that it feels the need to start over time and again. On the tablet side, if Microsoft is serious about usability, it should be providing a better touch keyboard — one that includes swipe-through typing, for example. I also wish the company had finally fixed Windows Update. Mobile users won’t put up with the way it works now — they are spoiled by seamless OTAs from Apple and even many Android vendors.
Perhaps the ultimate warning sign about Windows 10 for me is that for many, its positioning is summed up as being “no worse than the six-year-old Windows 7, while adding support for tablets and phones.” That sounds pretty silly, but maybe not far from the truth. I run a Windows 7 desktop for some of my business-critical applications right next to a couple of Windows 8.1 machines and a couple of Windows 10 machines. I don’t really feel any less productive when I’m on the Windows 7 machine, and I can’t imagine that I’ll upgrade it to Windows 10 and risk something breaking.
Tablets are certainly a different story. I’ve already put Windows 10 on almost all my Windows tablets, and suspect most of the small number of Windows tablet users will also. Unfortunately for Microsoft, Windows tablets are a relatively small market, and may never become mainstream.
Laptops are the most interesting case. While each version of Windows adds new power management features, that may not be enough to get laptop users to upgrade. For example, Microsoft keeps changing the WiFi settings interface, and for many of us, the new version is lame compared to the more powerful one that preceded it. Engineering laptops still ship primarily with Windows 7, and I don’t see anything about Windows 10 changing that. Mainstream laptops will get dragged along onto Windows 10 because of the Microsoft marketing machine, but I don’t know how many current laptop users will bother to take advantage of the free upgrade. No doubt that is part of why Microsoft is inflicting its Windows 10 adware on the already confusing Windows Update process.

After more than a decade of research, scientists at Stanford University have created a working computer based on the physical movement of water droplets. It’s a breakthrough in physical computing that gets at the most basic definition of a computer: any programmable device that can carry about logical (mathematical) operations. By combining cutting-edge theory in fluid dynamics with very-much-not-cutting-edge theory in computing, the team was able to create a synchronous computer based entirely on the physics of water.
As you might imagine, a computer based on the physical movement of water is much, much slower than a conventional computer based on the movement of electrons — but that’s beside the point. Nobody expects a new, super-fast liquid CPU, but by applying the principles of computing to the manipulation of matter, lead researcher Manu Prakash and his graduate students hope they can computationally revolutionize other areas of science.

Prakash is actually a bioengineer — his main goal with the project is to create a platform for robust, super-quick chemical testing. Their technique can direct potentially millions of droplets around a chip, simultaneously, and each of these can be loaded with a different chemical for testing. A well-designed chip could make months of complex chemical experimentation into minutes — once the chip has been designed and built, the experiment designed, and the samples made and loaded onto the chip itself.
The system works based on the continual flipping of an applied magnetic field. The chips, which are at present about half the size of a postage stamp, are embedded with tiny iron bars that are easily magnetized; arranging these bars in “Pac-Man-like” mazes provides discreet channels for the droplets to follow. Each droplet is infused with magnetic nanoparticles that make the water responsive to an applied magnetic field, so by flipping the polarity of these bars the team can decide which path each droplet will take through the bar-maze.
The system only works as a general-purpose computer because it is “synchronous,” meaning that it keeps the various operations marching to the same beat — the researchers say they could potentially control millions of droplets at once, with a scaled version of the same technology. In a conventional computer, each of these beats is called a clock cycle — in a water-drop computer, this beat is controlled by the flipping magnetic field. In both cases, the central timing mechanism makes sure that even thousands of different paths and interactions all proceed according to the same schedule, and can thus work together toward computational goals.
Some of the very earliest computers, like the UNIVAC I, had computer memory based on liquid mercury — in essence, the idea of representing computer data with physical matter is not new. What is new is the idea that the physical structure of the chip could be used to direct the movement of matter in a robust, pre-programmed way. In a best-case-scenario, this sort of paradigm shift in the approach to experimental chemistry could cause the sort of exponential efficiency increase electronic computers allowed in regular mathematics.
One big push in the quest truly next-generation medicine is so-called “organ on a chip” technology, which would allow scientists to test the effects of drugs and other substances on certain organs by running those substances through small, high-throughput stand-ins for whole organs of interest. With the ability to quickly and systematically test the interactions of thousands of different substances, that idea might someday plausibly reach the point of “individual on a chip.”
In the more foreseeable future, water-drop computing is a fascinating realization of something that was always theoretically known: computing is a fundamentally physical process (until quantum computing comes of age, I suppose), and as such can be expressed in the medium of physical matter. It’s far less efficient that way — but efficiency isn’t the only goal worth pursuing.

The 55-inch and 84-inch interactive displays marry white boards with presentations, voice with video, speakers with addressees, Android with iOS, and Windows 10 with conference rooms. The Surface Hubs will go on sale July 1, and on Sept. 1, they'll start shipping out of a Microsoft facility about 200 miles south of the company's Redmond, Washington, headquarters.
They're priced at US$6,999 for the 55-inch model and $19,999 for the 84-inch version.
The Surface Hubs were first shown to the world during a Windows 10 event back in January, but it appears the majority of onlookers' eyes were glued to Microsoft's augmented reality headset, the HoloLens, or searching out familiar elements in the new operating system.
Microsoft has been developing and manufacturing the Surface Hubs at a satellite campus a few miles outside of Portland, in Wilsonville, Oregon. All components except the screens were developed and produced at the facility, and Microsoft owns the company that produces the multitouch display technology for the Hubs.
The Surface Hubs are full-featured Windows 10 devices. The larger Hub features a 4K display, while the 55-inch variants output 1080p video.

Modernizing the Meeting

Meetings increasingly are dispersed, noted Brian Eskridge, a senior manager at Microsoft. About half of all corporate meetings include at least one remote participant.
"Surface Hub is designed to be engaging for everyone in a meeting," Eskridge told TechNewsWorld. "Remote participants that are dialing in have a great view of the conference room or ad hoc meeting space where the Surface Hub is located, and participants in the room have a great view of those remote participants."
That's all thanks to the dual 1080p cameras, inspired by Xbox's Kinect, that are built into the flanks of Surface Hubs, he pointed out.
The cameras "provide a full range of view for both people that are standing close to the Surface Hub, potentially whiteboarding on it, and for those who may be sitting at a conference table several meters away from the Surface Hub," said Eskridge.
As a full-fledged Windows 10 system "with all-in-one compute power," the Surface Hub is meant to be a workhorse in conference rooms, he added.
Businesses increasingly have been making decisions based on insights gleaned from data served up in real time, Eskridge pointed out, and it's that access to real-time data in an interactive experience that separates the Surface Hub from other displays on the market.
Real-time data access "ultimately enables a platform for amazing large screen applications that are powered by Windows 10 as a platform, but then extend out into a variety of industry verticals that may need business-specific or line-of-business applications," he explained.

At Home at the Hub

BYOD, or bring your own device, is now less a phenomenon and more the status quo, and the Surface Hub opens its arms to devices running on all major platforms. Hub users with Android, iOS or OS X devices can receive the same treatment that users of Windows or Windows Phone devices enjoy.
"Suddenly, you have a meeting room with that's live and active 10 hours a day," said Eskridge. "You have multiple individuals coming in and interacting with Surface Hub, and those people are bringing in their own devices and they're having great experiences on those other devices with our cross-platform applications like Office, or Skype for Business, or OneNote."
The Surface Hub is "incredibly impactful," and it's a worthy endeavor for Microsoft, which strives to empower individuals and groups alike, he added.

A Node in the Net

Microsoft last year started marching to the mantra "mobile first, cloud first." The development and release of touch-sensitive, big screen devices may appear to be a departure from that two-pronged strategy of mobility and cloud connectedness, but it is, in fact, integral to it.
"We're creating best-in-class experiences with our hardware that extend to our productivity software and services," Eskridge said.
Microsoft's mobile and cloud ambitions are trained on improving people's work lives and then following them home via their tablets and Windows Phone handsets.
The Surface Hub could serve as a new inroad into the workflows of enterprises, suggested Eric M. Jackson, CEO of CapLinked.
"Microsoft sees two trends that are threatening the longstanding dominance that Windows and Office have had with enterprises: Software as a service is rapidly expanding into the enterprise; and the number of non-Windows devices that people use for work is growing," he told TechNewsWorld.
Along with injecting itself into another area of enterprise workflows, the Surface Hub could inspire Microsoft's developer community as well, noted Charles King, principal analyst at Pund-IT.
"The fact that the Surface Hub will also support common Windows applications and frameworks -- in contrast to the original Surface's less open environment -- means that many in Microsoft's developer community should be inspired to write applications for it," he told TechNewsWorld.

Nothing Succeeds Like Success

The Surface Hub and other hardware, such as the latest Surface Pro, indicate that Microsoft has a new attitude, and its OEM partners should be on notice that the company will produce hardware when they won't, King said.
"I believe that under CEO Satya Nadella, the company is moving aggressively to meaningfully highlight the capabilities of its core technology assets, far more so than when Steve Ballmer was leading the charge," he remarked. "At that point, numerous projects were left unfinished, or dropped after they faced initial challenges."

HGST (Formerly Hitachi’s hard drive division) has been talking about its helium storage devices for several years and the firm is finally ready to ship the new drives for enterprise deployments. The Ultrastar Archive Ha¹⁰ isn’t just filled with helium — it also uses new Shingled Magnetic Recording (SMR) to write data to the disk. While this allows for unprecedented areal density, there are some caveats that make the drive ill-suited to conventional consumer applications. It’s an offshoot of the earlier-launched He⁶, which uses helium, but not SMR.
First, a word on SMR itself. SMR is the latest advance in recording technnology designed to ensure that consumers and businesses have enough storage space for… erm, office documents. It’s my personal opinion that hard drive manufacturers don’t get nearly enough credit for the work they’ve done to expand storage capacities. Imagine if Ford rolled out a new 2016 Escort capable of holding the population of China in a smaller footprint than its 1981 model year, and you’ve got some idea of just how drastically hard drives have advanced in the intervening decades.

Unfortunately, all good things come to an end, and conventional HDD scaling (even assisted by perpendicular recording) is hitting a wall. Areal density becomes difficult to scale using conventional methods because it’s no longer possible to focus a sufficiently powerful magnetic field on a single bit of the drive. Shingled magnetic recording boosts drive density not by scaling the areal density to ever-higher levels, but by laying tracks across each other, in shingled fashion.

The advantage of laying the tracks down in this fashion is that you pack data more closely together. The disadvantage is that rewriting tracks will damage the data on subsequent tracks. The only way to prevent this is to read the entire data block, modify the necessary section, and then re-write the rest of the track. This can lead to huge write amplification — if a 4KB update needs to be performed to a 64MB area of track, then the entire 64MB has to be read into RAM and laid back down with the modified 4K section. To reduce the impact of this write amplification, the drives are divided into bands — contiguous blocks of data that are treated as a unit.
It’s important to avoid random reads and writes as much as possible when using SMR, however, which is why HGST is marketing these drives as “cool” to “cold” storage — meaning data that’s written very few times and accessed only on occasion. If the drive is being regularly written and re-written, the performance penalties will quickly become severe. The HGST drives also require extensive modification and drive software in order to operate properly.

Hitachi has an open-source project, libzbc, that can be integrated into Linux to implement support for its now Ha¹⁰ drives. Absent such support, the drives can’t function — these aren’t your typical plug-and-play hard drives.
Right now, it’s hard to see where SMR drives will fit into future consumer products. Tech Report, erm, reports that the rated performance on the new hardware is just 157MB/s sequential read and 68MB/s sequential write. Meanwhile, adding the helium capabilities to drive up storage densities will add its own significant costs. All drive technologies require a launch period before they start to hit attractive prices, but pushing the envelope on HDD storage through noble gases and particular recording methods with some noted drawbacks seems an ill fit for the larger consumer market. It’s worth noting that SMR isn’t the only game in town for pushing the envelope on hard drive capacity — another technology, Heat Assisted Magnetic Recording, or HAMR, is currently expected to reach market by 2016 or 2017.
