​Chrome on Windows 10: Google gains 15 percent speed boost using Microsoft tech

Google says it's used Microsoft's PGO technology to make its Chrome browser load pages faster on Windows.

Speed is one way Google can make Chrome more appealing to Windows users in the face of competition from Microsoft's Windows 10 Edge browser.
For its latest effort to make Chrome faster, Google turned to Microsoft's implementation of Profile Guided Optimization (PGO) to cut Chrome's new tab page load times by 14.8 percent, page load times by 5.9 percent, and start-up times by 16.8 percent.
The PGO-based speed improvements are available in 64-bit Chrome on Windows since version 53, which Google released at the end of August, and this week's version 54 for 32-bit Chrome.
PGO is one way to optimize compilers by identifying which functions of a program are less or more frequently executed during runtime.
Developers can build a special version of the app and put it through its paces under common user-interaction scenarios. The results inform how best to optimize the app. The tool is available with Microsoft Visual Studio, which has supported PGO since Microsoft Visual C/C++ 2005.
It's not clear whether this is the first time Google has used the tool to improve Chrome on Windows, but the search firm notes it can be helpful for a software project as large as Chrome, which has more than a million functions in its source code.
Google's optimization process is focused on its nightly Chrome build process, which uses a special version of Chrome to track function usage.
"PGO then optimizes those high-use functions for speed, in some cases increasing the binary size of those functions. To balance out that increase, PGO also optimizes less-used functions with smaller, though slightly slower code. These trade-offs result in higher overall performance, and a smaller overall code footprint," explained Google's Sébastien Marchand.
Google is also working on improving Chrome's power and memory consumption. Chrome 55, due out in December, will have a newly-optimized V8 JavaScript engine that early testing has showed can deliver huge reductions in memory usage.
According to Marchand, PGO-derived memory optimizations are also helping deliver overall performance improvements in Chrome. It does this by moving rarely-used functions away from frequently-used ones.
"This results in more optimal use of the CPU instruction cache by avoiding caching of less-used code, increasing overall performance," said Marchand.

Virtually there: How Google is readying VR for you

Google has an ambitious plan for the future: help nearly anyone with a smartphone to experience virtual reality.



The technology industry is preparing for an onslaught of new devices that mount on your head, immersing you in computer-generated worlds ranging from space battles to Spanish villas.

The trend is called virtual reality, or VR, and the technology is moving from science fiction to store shelves within the next year. Once thought of as a gimmick from the early '90s, VR is now one of the hottest markets in the tech industry as low-cost components and powerful software have made replicating the real world easier and more lifelike.

As it happens, some of the biggest companies in the world are staking out a position offering the highest-quality devices, capable of displaying complex imagery and inserting users in a digitally created world that feels like our own.

Google? It wants to help everyone else.

The search giant will do this with a product called Cardboard, a simple device made from Velcro, a button, some lenses and folded cardboard. The project was first announced at the company's I/O developer conference last year, but Google returned to this year's show with an updated version that works with devices whose screens measure up to six inches diagonally. Google also showed off a new version of its Cardboard smartphone app. Perhaps the biggest change: Cardboard and its apps will work with the iPhone, in addition to Android devices.

The takeaway: Cardboard may sound cheap, but it's a powerful play for getting VR out to everyone and their mother.

VR for the masses

All told, the device costs less than $20, a fraction of the $350 or more that most high-end headsets are expected to command. The trick: Your smartphone is both the engine and the display, sliding easily into the front of the contraption and viewable through a pair of off-the-shelf lenses.



For Google, this is business as usual. The search company has made its name by offering technology and software broadly and at little or no cost, inspiring millions of people to flock to its products. It's how the company helped make its Android software for mobile phones the most popular in the world.

 And for the broader industry, Google's Cardboard could be the device that introduces VR to people from rural India to downtown San Francisco, all while companies like Facebook-owned Oculus, Sony, and others design expensive headsets requiring powerful hardware to generate 3D images.

"In many ways what's going on in VR is similar to what happened in mobile seven years ago," said Andrey Doronichev, product manager for VR apps at Google, referring to the earliest days of Android. Google hopes Cardboard will do what low-cost Android smartphones did back then: quickly make technology available to billions of people.

With Cardboard, Google can "introduce an incredible amount of people to VR in a relatively inexpensive way," he said.

Yet critics of Cardboard say it could undermine the industry's attempts to attract the broader public. Since the last major attempts to sell VR almost two decades ago, enthusiasts have warned against overhyping the technology and selling it before it's ready.

The fear is that if VR isn't a great experience the first time someone tries it out, it may poison public perception.

Doronichev thinks that while the experience is an obvious downgrade from wearing an expensive VR headset powered by a PC or game console, the overall impression is comparable.

Moore's Law is the reason your iPhone is so thin and cheap



Intel co-founder Gordon Moore's observation 50 years ago set the groundwork for self-driving cars on the road and computers in our pockets today.


To get a sense of what society owes to Moore's Law, just ask what the world would look like if Intel co-founder Gordon Moore never made his famous 1965 observation that the processing power of computers would increase exponentially.



CNET

"It is almost unimaginable," said Genevieve Bell, a cultural anthropologist for Intel.

"The implications would be so dramatic, I struggle to put it in words," said Adrian Valenzuela, marketing director for processors for Texas Instruments.

Jeff Bokor, a professor of electrical engineering and computer science at the University of California, Berkeley, found at least one: "Cataclysmic."

The comments aren't wild hyperbole; they underscore just how significant an impact one little observation has had on the world. Moore's Law is more than a guideline for computer processor, or chip, manufacturing. It's become a shorthand definition for innovation at regular intervals, and has become a self-fulfilling prophecy driving the tech industry.

Are you happy about your sleeker iPhone 6 or cheaper Chromebook? You can thank Moore's Law.


With Sunday marking the 50th anniversary of Moore's observation, we decided to take stock of Moore's Law. CNET staff reporter Ben Fox Rubin offers an in-depth look at the work that semiconductor manufacturers are putting in to make sure the rate of improvement is sustainable. Tomorrow, CNET senior reporter Stephen Shankland explores alternative technologies and the future of Moore's Law while senior reporter Shara Tibken looks at Samsung's lesser known presence in the field.

But first, let's explore the effect of Moore's Law throughout history -- and start by dispelling some misconceptions. Most importantly, Moore's Law is not actually a law like Isaac Newton's Three Laws of Motion. In a paper titled, "Cramming More Components onto Integrated Circuits," published by the trade journal Electronics in 1965, Moore, who studied chemistry and physics, predicted that the number of components in an integrated circuit -- the brains of a computer -- would double every year, boosting performance.



A decade later, he slowed his prediction to a doubling of components every two years.

It wasn't until Carver Mead, a professor at the California Institute of Technology who worked with Moore at the Institute of Electrical and Electronics Engineers, coined the term "Moore's Law" in 1975 that it gained widespread recognition in the tech world. It became a goal for an entire industry to aspire to -- and hit -- for five decades.

"[It's] a name that has stuck beyond anything that I think could have been anticipated," Moore, now 86, said in an interview with Intel earlier this year.


A self-fulfilling prophecy

Moore's Law specifically refers to transistors, which switch electrical signals on and off so that devices can process information and perform tasks. They serve as the building blocks for the brains inside all our smartphones, tablets and digital gadgets.

The more transistors on a chip, the faster that chip processes information.

To keep Moore's Law going, chip manufacturers have to keep shrinking the size of the transistors so more can be placed together with each subsequent generation of the technology. The original size of a transistor was half an inch long. Today's newest chips contain transistors that are smaller than a virus, an almost unimaginably small scale. Chipmakers including Intel and Samsung are pushing to shrink them even more.

But size doesn't really matter when it comes to appreciating Moore's Law. More important is the broader idea that things get better -- smarter -- over time.

The law has resulted in dramatic increases in performance in smaller packages. The Texas Instruments processor that powers the navigation system in a modern Ford vehicle is nearly 1.8 million times more powerful than the Launch Vehicle Digital Computer that helped astronauts navigate their way to the moon in 1969.


And Apple's iPhone 6 is roughly 1 million times more powerful than an IBM computer from 1975 -- which took up an entire room -- according to a rough estimate by UC Berkeley's Bokor. The iPhone, priced starting at $650, is also a lot cheaper than a full-fledged desktop computer selling anywhere between $1,000 and $4,000 a decade ago -- and it can do so much more.

Just as critical is the time element of Moore's Law: the doubling of transistors every two years meant the entire tech industry -- from consumer electronics manufacturers to companies that make the equipment to manufacture chips and everything in between -- had a consistent rate that everyone could work at.

"It created a metronome," Bell said. "It's given us this incredible notion of constant progress that is constantly changing."

It also set a pace that companies need to keep, or else get left behind, according to Moore. "Rather than become something that chronicled the progress of the industry, Moore's Law became something that drove it," Moore said in an online interview with semiconductor industry supplier ASML in December.

While he didn't think his observation would hold true forever, chipmakers don't seem to be slowing down their efforts. "It's a self-fulfilling prophecy, so to the industry it seems like a law," said Tsu-Jae King Liu, a professor of microelectronics at UC Berkeley.

Life without Moore's Law

Nowadays, everyone assumes technology will just get better, faster and cheaper. If we don't have a sophisticated enough processor to power a self-driving car now, a faster one will emerge in a year or two.

Remove Moore's Law, and that assumption no longer holds true. Without a unifying observation to propel the industry forward, the state of integrated circuits and components might be decades behind.

"It's an exponential curve, and we would be much earlier on that curve," Valenzuela said. "I'm happy to say I don't have to carry my 1980s Zack Morris phone."

Intel's Bell imagines a more "horrifying" world without integrated circuits, one in which everything is mechanized, and common tropes of technology such as smartphones and even modern telephone service wouldn't exist. "The Internet would have been impossible," she said.

Reviews Reveal The New MacBook The Future Of Laptops, But With A Catch




The new 12-inch MacBook from Apple Inc may be the most beautiful laptop ever (to date), but several tech sites suggest that users looking for power should skip the first generation — and wait for the next one, probably next year?

Reviews from several trusted sites pointed out that the new 13.1 mm thick MacBook is a promising new “category” within the laptop market, but it lacks the necessary power to run many applications. They also suggest that Apple would introduce a new model next year that may include more USB-C ports and better processors for improved performance.

In case you’re wondering, the new 2-pound MacBook with 12-inch Retina display is not replacing the MacBook Air, although they have similarities. The new MacBook (without the “air” branding) is being positioned as an alternative to iPads.

This new product is also more expensive than the MacBook Air (and the iPad, of course) with base price of $1,299 with 1.1GHz dual-core processor and 256GB on-board flash storage, compared to Air’s base model with asking price of $899. Apple is also selling a higher-end 12-inch model for $1,599 which ships with 512GB flash storage and dual-core processor clocked at 1.2GHz.

According to CNET, users who can live “with its limitations” would enjoy the laptop’s groundbreaking design. Meanwhile, the Verge, known for its mostly positive reviews for Apple devices (including the Apple Watch), claims that the new MacBook is the “future” of laptops — although the review is indirectly suggesting that users should wait for the next model that would address all the limitations of the first model.

Another review worth mentioning is from Macworld, also known for its mostly-positive reviews for Apple products. The site revealed that one of the laptop’s bells and whistles is actually a “con” — the MacBook’s keyboard. The review said the butterfly mechanism on each key, which delivers reduced travel from the surface to the bottom of the key, is making “fast typing harder, and less satisfying.”

And similar to other reviews, the Macworld piece also criticized the laptop’s single USB-C port which demands carrying more adapter.

New MacBook Is The Future Of Notebook Personal Computing
Phil Schiller, the firm’s senior vice president of worldwide marketing, is confident that the new MacBook is the “future of netbooks”. In a press release earlier last month, Mr. Schiller underlined the product’s build quality, thinness, and portability, instead of highlighting its capability to run applications.

Apple is also not shy to admit that the new MacBook was built using the same techniques used to make iPhones and iPads — with the main focus on making everything thin, light, and appealing.

Drone Makers Seek Traffic Control





The commercial use of drones remains mostly illegal in the U.S. All the same, businesses are moving ahead with ways to profit from the small helicopters, with some assistance from the Federal Aviation Administration. In February the FAA, which is preparing drone rules, agreed to exempt State Farm from the prohibition, letting the insurer test the use of drones in claim inspections. On March 19 the agency granted Amazon.com a waiver to continue testing its package-delivery drones. And in Portland, Ore., startup SkyWard is pushing forward with a drone traffic control system that will allow thousands of the machines to fly through cities without colliding with one another or endangering people.

SkyWard is working with NASA and the world’s three largest drone makers—DJI in China, 3D Robotics in the U.S., and Parrot in France—to demonstrate that swarms of drones can safely coexist in crowded airspace. “It’s about applying the regulatory framework to a new kind of aviation infrastructure,” says co-founder and Chief Executive Officer Jonathan Evans. The software project, Urban SkyWays, is designed to resemble a conventional air traffic control system at altitudes of 1,200 feet or lower, says Parimal Kopardekar, who manages NASA’s experiments on drone coordination and whose researchers are contributing their time to the project.

Urban SkyWays would load SkyWard’s cloud software onto each drone and the computer used by its pilot, says Marcos Osorno, SkyWard’s chief technology officer. The software plots the paths of all drones equipped with it, so a dispatcher working for a company such as Amazon or UPS could log on to the system to file a flight plan and receive an automatically generated route, from pickup point to destination, to help a drone avoid other machines. The flight plans will also take into account local and federal regulations. “The first question our system has to answer is, ‘Where is it safe to fly?’ ” Osorno says.

“There are rules of the road up there, and SkyWard is extending them to drones.”—SkyWard CEO Jonathan Evans

At this point, not very many places, and not very far. If adopted, the FAA’s rules for commercial drones will restrict flights to their operators’ line of sight. They would also ban flights above unprotected bystanders. Although the FAA acknowledges that technological advances may persuade it to tweak or rewrite the draft rules, slated to take effect in the next year or so, there are no guarantees.

Evans says his work as a helicopter pilot left him confident that drones can operate safely in cities. “I flew in the low airspace in urban areas all the time,” he says. “There are rules of the road up there, and SkyWard is extending them to drones.” Evans and Osorno met while flying U.S. Army helicopters in Germany more than a decade ago. Evans later flew medical choppers in Anchorage and Portland.

SkyWard and its partners plan to make money from annual subscriptions paid by drone operators to use the traffic control software. For now, SkyWard is consulting and working with companies on drone-pilot training and compliance with FAA regulations. In July the 12-employee company received $1.5 million in venture funding from Voyager Capital, Draper Associates, and Toivo Annus, the former engineering chief at Skype. It declined to disclose revenue.

The maximum altitude for SkyWard’s drone traffic control

Exelis, a major U.S. defense contractor, will unveil a drone-focused companion to its manned aircraft tracking system this month, according to program manager Christian Ramsey. The SkyWard engineers say their expertise in low airspace and the participation of the three leading drone makers give them an edge. Besides, Evans says, drone traffic control is more akin to managing “flying cell phones” than Boeing 747s.
SkyWard and its partners are planning demonstrations of their traffic control software from May through September in London, Vancouver, Las Vegas, and Portland. Osorno and Evans say they’re spending most of their time working out demo routines that will be duly impressive—and safe.
3D Robotics has raised $110 million to bring commercial drones to the mainstream. “Doing it safely and responsibly is a big part of that,” says CEO Chris Anderson. “We’re very much counting on SkyWard to ensure the way.”

DJI Phantom 3 hoists 4K video and live streaming into the sky





DJI's Phantom series have become something of a benchmark for consumer drones -- or quadcopters, if you prefer -- thanks to their simple setup, ease of flying and relatively low price. The previous model, the Phantom 2 Vision+ , brought a stabilising gimbal for the camera for more professional-looking shots. Its overall camera quality left something to be desired, however.

With its new Phantom 3 drones, DJI is hoping to fix that issue. Two versions of the drone will be available -- the Phantom 3 Professional, which shoots video in 4K resolution, and the Phantom 3 Advanced, which is functionally the same, but shoots video in 1080p. Both models have updated camera sensors, which promise improve dynamic range, both are equipped with ground-scanning sensors to let them fly indoors with greater stability, and both can stream your aerial footage live to YouTube.

Priced at £899 or $999 for the Advanced model and £1,159 or $1,259 for the Pro, they're hardly dirt-cheap, but they're significantly less than the many thousands you can pay for professional drones. The Phantom 2 Vision+ is still on sale for around £920 or $1,150, so it's cheaper, even with the upgraded camera and ground sensors, and adding 4K isn't a huge cost either. Australian prices aren't yet available, but the UK prices convert to around AU$1,740 and AU$2,245.

Both drones are up for preorder now, globally, and shipping is due to start towards the end of April.

Design

The Phantom 3 looks very similar to DJI's previous models, with the white plastic body, four rotors and fixed landing legs slung beneath. It's light enough to carry in one hand and when you unscrew the rotor blades, it's small enough to fit into a decent-sized backpack. It's certainly more portable than the much larger Inspire 1  drone.

It feels as well built as before -- a drop from 200ft above the ground will probably result in the Phantom shuffling off its mortal coil, but the odd bump into walls or small crashes while you're getting the hang of flying won't faze it. The rotor blades are easily replaceable if you do snap a few.

Camera

As before, the camera is slung beneath the drone -- but it's had a bunch of significant upgrades. Its sensor has been changed from the previous model, which apparently helps improve dynamic range, resulting in more balanced bright skies, which was something of an issue for the previous version. Although DJI initially told me it was physically larger than its predecessor, both models have 1/2.3-inch sensors -- the same size seen on DJI's pricier Inspire 1 and the previous generation Phantom 2 Vision+.

The headline feature on the Professional model is of course its ability to shoot video in Ultra HD 4K resolution. It can do this at frame rates of 23, 24 or 30 frames per second too, so you'll still get smooth shots. The benefit of 4K footage isn't just to look crisp on a 4K monitor, it also gives you a lot of room to crop into the frame, while still maintaining full HD quality or better.

The lens on the camera has a 90-degree field of view, which is narrower than the previous version. That may seem a step down, but it's actually for a very good reason. The extreme wide angles previously used caused distortion of the image, particularly at the corners, meaning a lot of digital correction had to be used, if the footage was for a professional purpose. The smaller field of view will help keep distortion down and require less, if any, post processing.

The camera is mounted on the same three-axis stabilising gimbal, which automatically corrects for any slight movements of the drone, as well as smoothing out vibrations from the rotors. It results in considerably smoother footage, without the unpleasant jerks and bumps seen from drones that don't use stabilisation -- including DJI's Phantom 2.

One of our criticisms of the previous model was that it could struggle to balance a very bright sky against a darker ground, which was something of an issue for a camera designed for filming both the sky and the ground. Hopefully this new model will fare better.

Features

Behind the camera unit are a couple of new sensors. They point down and detect patterns on the floor to lock on to, in order to remain stable when flying indoors where GPS signal (which is used for stability outdoors) may not be available. Although you could technically fly any of the previous drones indoors, the new sensors mean it will have much better stability and is able to hover in a fixed location with no effort on your part.

The controller is roughly similar to previous versions, with two main control sticks and a clamp to hold a smartphone or tablet, which acts as the display for the drone's camera. On each top corner of the controller you'll find buttons for quickly changing camera settings and starting and stopping recording while the drone is in the air.

The DJI app (on iOS and Android) still provides a live video feed of the drone's view, and gives information about battery, flight time, height and speed. It also allows you to change in-depth camera settings, such as exposure and white balance. A couple of new features have been added, including a training mode, that lets you practise flying a virtual drone on the screen, using the controller, helping you get the hang of flying without trashing your pricey new gadget. In my experience, however, the Phantom drones are extremely easy to learn to fly.

DJI has also added the ability to stream live video from the drone to YouTube, in 720p resolution. That will be great news for those of you who want to give your YouTube fans an overhead view of your garden, but it could also have great value for journalists wanting to stream live footage of events around the world. How this works in practice remains to be seen.


Other features include the existing return to home function, which safely brings the drone back to you when the battery is about to give up, and the battery itself has been made slightly larger. DJI reckons you can get around 20-23 minutes of flight time from a single charge, which is probably plenty if you're just flying around outside your house, but you'll almost certainly want to buy a few spares if you're using it professionally.

Outlook

DJI's new Phantom 3 drones maintain the overall simplicity and ease of use of the previous Phantoms. The addition of 4K on the Pro model and the indoor flying and supposedly improved image sensors on both models should help them appeal even more to enthusiastic amateur filmmakers who want to experiment with aerial footage, but don't want to break the bank to get their shots. We'll look forward to reviewing them in full soon -- stay tuned.

New gay family emoji appear on Apple's iOS





USERS of the Apple iPhone and iPad got a new palate of emoji on Wednesday, including a group of alternative or gay family illustrations.

The new emoji appeared on an update to Apple's mobile operating software, iOS 8.3, which was rolled out on Wednesday. Some test versions of the software had been in use since February.

The new emoji include illustrations of families with families that include two male parents or two female parents.

The updated emojis also include characters of various races, as previously announced by the Unicode Consortium which sets international rules for text and characters to insure consistency across platforms.

Apple made no comment about the update, but earlier this year in a statement to media that it "supports and cares deeply about diversity."

Apple chief executive Tim Cook announced last October he was "proud to be gay," following long speculation about his sexual preference.

Living with the new Apple Watch







Bani McSpedden, the watch editor of the Australian Financial Review and editor of watch-next.com, was invited to pre-trial the Apple Watch. These are his first impressions.

I've been wearing the Apple watch – the polished steel version - since taking delivery of it at Apple headquarters in Silicon Valley on April 1 (after midday, I should add).

The first thing I can tell you is that it's quite an addictive little device.

Is it a replacement for a traditional watch? No.  It's not so much a mesmerizing machine as a mighty module, and it doesn't have the same character or charisma.

A mighty module

But it's better than just being another way of telling the time, and in many respects is a real advance on the traditional watch.

For more details about the Apple Watch go to watch-next.com
How so? On the wrist you discover it's beautifully crafted, incredibly tactile, and so comfortable to wear you forget it's there.

Even little details like strap changes have been addressed in an ingenious way. The straps on Apple's watch – in four styles from silicon to fine leather and metal versions - slide into the case rather than loop around a spring bar, making switching from one to another as simple as pressing a recessed button.

Why traditional watch-makers haven't come up with something like this after all these years – well, a century – is a mystery.

Endlessly customisable

But while the devil – or in this case the gods – might be in such detail, where the Apple watch modifies old habits is its array of options and functions, not to mention fun stuff, that has you glancing at it for much more than just the time.

The options let you customise the watch face in an endless variety of ways – choose from analogue, digital or graphic displays, the later ranging from animated Mickey Mouse faces, to floral blooms.

I opted for a rather traditional-looking black face, stripped down to just the 12, 3, 6, 9, numerals, with white hour and minutes hands and an orange seconds hand. Yes, you've a whole palette of colours at your disposal.

After setting that up it was time to delve into the seemingly endless functions you now have on your forearm, ranging from fitness prompts and apps to weather forecasts, world time, stock prices, notifications, messages and maps.

You access these functions in three ways, through the watch's touch-sensitive face, through a unique 'digital crown', and via an elongated button underneath the crown which provides a shortcut to calling or messaging contacts.

Did I find this a bit complicated?  No, but it takes a little learning, after which it becomes intuitive. It's not unlike learning how to use an iPhone for the first time, which of course is the base station you use to set up the watch; the mother-earth around which it orbits.

Wrist action

Which raises the question - why not simply use your iPhone?

At my briefing Apple's designers told me that one of the aims of the watch, almost contrarily, was to free users from pulling out their phone so frequently. To make it easier to access things in an unobtrusive way.

I took this with a grain of salt until I began wearing the watch, which alerts you to the arrival of a message with a gentle tap on the wrist, and lets you reply with just a tap on a pre-determined selection of responses which are automatically tailored to reflect the gist of the message.

I found I was able to respond to three messages during one meeting without anyone in the room noticing. Brilliant.

In a similar category – and I'm still not sure if this comes under the heading of 'practical' or just plain fun, where the Apple really differs from your usual watch, is you can talk to it – and it responds.

Call it the Dick Tracy feature, but thanks to Apple's Siri voice command system, you can ask the watch to instigate various tasks without touching a thing.

The watch comes alive with the instruction "Hey Siri", after which you can ask it call a contact, brief you on the weather, or guide you to a destination – did I mention the watch displays maps, and you can zoom in using the digital crown?

Fade to black

If this is all positive, I found a couple of things less so. While lifting the wrist automatically brings the dormant watch-face alive, there's a short lag, say one second, which is a second longer than it takes to glance at your standard watch.

Then, once there, that image seems to disappear rather too soon. Watch-loving folk find staring at a watch face a strangely calming experience, and for it to fade to black too quickly is a little disappointing.

But in short, my week with the Apple Watch has been a week experiencing a different relationship with my forearm. Quite simply it's not so much a watch, certainly not as we know it, as a new generation of wrist-wear.

Watch out?

And what about my B.A. (before Apple) timepieces? Will they now simply lie dormant in the sock drawer, ticking over in the hope they'll be rediscovered or favoured now and then?

The truth is, I've found that if I'm only wearing the Apple upstart, I miss them, and obviously won't stop wearing them. Like a fountain pen versus a roller-ball, there's something truly special about cogs and springs – and, something you never have to charge up. (Not that the Apple was such a chore here – mine lasted all day and evening, I simply charged it overnight alongside my phone.)

Oddly for me, my left wrist seems the natural place for the Apple, whereas I normally wear my watch on the right wrist. What this means is there's really no contest at all – just a happy answer as to why God gave us two wrists.

Bani McSpedden is watch editor of the Australian Financial Review and editor of watch-next.com. He travelled to Apple's headquarters in California as a guest of Apple.

Will this one-armed robot puts you out of a job?

Sawyer the one-armed robot can do many things. It can assemble goods on the factory floor day after day without tiring, taking toilet breaks, or asking its boss for a raise.




What Sawyer can't do, however, is understand the human debate swirling around its potential to revolutionize manufacturing -- and society -- as we know it.

Depending on who you speak to, robots like Sawyer either foretell a new era of global unemployment, or save us from the kind of dull jobs you wouldn't wish on your own child.
It's a lot of responsibility for a 3.3 foot tall robot with one arm and a touch screen for a face. Barely a month old, Sawyer has already made a name for itself as the new kid on the robotics block with a super-flexible limb able to perform intricate tasks once thought out of the realm of machines.
Machines making machines

Expect to see Sawyer tinkering with circuit boards alongside its human colleagues on the factory floor, says creator Rodney Brooks, of Boston-based company Rethink Robotics.
"We're aiming at the electronics assembly industry -- and most of that will be in Asia," said the Australian-born engineer, who is also behind the bomb disposal PackBots that were used by the U.S. military in Iraq.

Sawyer's unusual one-arm design came after analyzing over 150 factory tasks, and finding many could be done with just a single limb.
The $29,000 robot will be a "baby brother" to Baxter, a larger two-armed robot launched in 2012 and better suited to heavy lifting than fiddly maneuvers. Both have animated eyes that look in the direction they're about to reach -- just like humans.



Rise of the robots

But Sawyer's increased dexterity could also bring us one step closer to what Silicon Valley entrepreneur Martin Ford describes as the "End Game" of manufacturing -- a time when factories are almost entirely manned by machines.

"Robots are moving into the realm where they're beginning to compete with people for those kinds of jobs that rely on hand-eye coordination -- things that up until now, only people could do," said Ford, who is also the author of new book "Rise of the Robots: Technology and the Threat of a Jobless Future."

"What are we going to do for the people who are displaced? The evidence suggests that there aren't going to be enough new jobs created in other areas. There will be some -- for engineers and so forth -- but the numbers don't match up."

As robots become more advanced, it's not just factory workers at risk, but service staff and office employees, he added. "This is a huge issue -- something ultimately in the order of climate change, in terms of the challenge it represents to society."

Show me the workers

Brooks sees things differently, arguing that companies are already struggling to find enough people willing to do menial manufacturing jobs -- let alone robots.
"If it was the case that people were lining up wanting factory jobs, then that would be a valid fear. But in the U.S. the average age of a factory worker is over 55 -- people don't want those jobs!" says the former director of MIT's Computer Science and Artificial Intelligence Laboratory.



"When people say to me 'robots are going to take away jobs,' I always ask them 'do you want your child to work in a factory?' And they always say to me 'oh no, not my child, but you know, other people's children.'"

Brooks says dexterity is one of the biggest challenges in robotics today.
"We just don't know how to build dexterous hands. It's an area where there hasn't been much progress in the last 40 years," he said. "So that's one of the reasons robots are not going to take over the world and replace everyone," he said.

"I think this is where Hollywood confuses everyone. Robots are really not very smart. They don't understand what they're doing or why they're doing it," added the 60-year-old engineer, who first started building robots as an eight-year-old.

Old world jobs

Both Sawyer and Baxter are named after archaic English words for professions -- "Sawyer" meaning someone who saws wood, and "Baxter" meaning a woman who bakes.
"The names are for old professions that aren't in use anymore," explained Brooks.
Whether they will one day replace the occupation of "factory worker," remains to be seen.
