Home lighting latest technology.

Home lighting the latest technology to go wireless:

Melbourne-based technology startup LIFX has the not-so-humble goal of reinventing the light bulb.

Founded by 40-year-old Australian inventor Phil Bosua, the company sells a $129 multi-colour LED light bulb that’s almost as easy to install as a regular bulb. It screws into existing light sockets, but rather than being turned on and off at a light switch, it’s wirelessly controlled from an iPhone or Android phone.

Far from the traditional white or yellow hues of a regular light bulb, the LIFX has access to a palette of more than 16 million colours. From the free app, users can manage each LIFX light bulb in the house, set the colour and brightness of bulbs individually or as a group, and set up lighting effects such as music visualisation (where the light pulses in time to music) and candle flicker.

ess than a week after it made its debut on the crowdfunding site Kickstarter in September 2012, it had raised $1.3 million – well above its original $100,000 target – making it one of the most successful Kickstarter projects to date.

Since then, the company has shipped more than 100,000 bulbs to about 70 countries, and its goods can be purchased online as well as through retail partners such as Best Buy in the US and Harvey Norman in Australia.

As with many great ideas, Bosua first came up with it while he was drinking beer with a friend.

‘‘A friend of mine told me he was renovating his house and needed to put a light switch in without having to cut up bricks and run a wire down the wall,’’ Bosua says.

‘‘He said, ‘You’re the inventive type – do you know any way you can turn your lights on and off wirelessly?’’’

Bosua’s first thought was that it could be done with a smartphone, but when he did some research he discovered there was nothing on the market. This, he says, was literally his light-bulb moment.

Technology analyst firm Telsyte forecasts that the smart lighting market in Australia will exceed $100 million by 2017. Over the next three to four years, it’s expected to reach mainstream status, driven by falling prices and centralised management platforms that leverage iOS and Android.

‘‘In the past, if you wanted to do home automation, it would be very expensive. You’d have to put in cabling, you’d have to rip out walls,’’ says Telsyte managing director Foad Fadaghi. ‘‘Today, the cost effectiveness of wireless and cheap Wi-Fi components has made it a lot easier to adopt home automation systems. What we’re seeing now is the democratisation of smart home technology.’’

LIFX has stiff competition from larger players in the smart home technology category. Multi-national technology company Philips released the Hue smart LED bulb one month after the LIFX hit Kickstarter, and beat the Melbourne start-up to the market by more than a year. At $249.95 for the starter pack (which includes three light bulbs and a bridge that needs to be plugged into a Wi-Fi router) and individual light bulbs for $69.95 each, the Hue is also cheaper than the LIFX.

Belkin, one of the leading providers of do-it-yourself smart home automation gadgets, will soon be releasing an even cheaper smart LED light bulb that hooks into the company’s WeMo ecosystem of smart power switches, motion sensors and webcams. The starter pack will cost $169.95 and include two smart light bulbs and a bridge to plug into the Wi-Fi router. Additional light bulbs will be available for $49.95 each.

But Bosua isn’t sweating his competitors. At the recent international 2014 Edison Awards, LIFX beat the Philips Hue to win the gold medal for smart systems in the consumer goods category.

Last week LIFX also secured $12 million in Series A funding, bringing the company’s total funding to $16.6 million.

‘‘We’re thinking within the next two to three months all of the features we originally promised on the Kickstarter project, such as timer scheduling and auto-increasing and dimming lights, will be completely built, and then we’ll be able to start rolling out some of the other really cool things that we’re working on,’’ said Bosua. ‘‘We’re also going to release different form factors, and we’re really far down the prototype stage of a LIFX light switch.’’

Google Glass wearers can steal your password

By usama.asif July 14, 2014: 2:26 PM ET

Remember the kid who tried to cheat off you by looking over your shoulder to copy your test answers? He's baaaack.

But this time he's wearing Google Glass -- and he's after your iPad PIN.

Cyber forensics experts at the University of Massachusetts in Lowell have developed a way to steal passwords entered on a smartphone or tablet using video from Google's face-mounted gadget and other video-capturing devices. The thief can be nearly ten feet away and doesn't even need to be able to read the screen -- meaning glare is not an antidote.

The security researchers created software that maps the shadows from fingertips typing on a tablet or smartphone. Their algorithm then converts those touch points into the actual keys they were touching, enabling the researchers to crack the passcode.

They tested the algorithm on passwords entered on an Apple (AAPL, Tech30) iPad,Google's (GOOGL, Tech30) Nexus 7 tablet, and an iPhone 5.

The software can be applied to video taken on a variety of devices: Fu and his team experimented with Google Glass, cell phone video, a webcam and a camcorder. The software worked on camcorder video taken at a distance of over 140 feet.

Of course, pointing a camcorder in a stranger's face might yield some suspicion. The rise of wearable technology is what makes this approach actually viable. For example, a smartwatch could stealthily record a target typing on his phone at a coffee shop without drawing much attention.

Fu says Google Glass is a game-changer for this kind of vulnerability.

Intel’s Anniversary Pentium

Intel’s Anniversary Pentium may be the ultimate budget gaming CPU......

BY usama.asif on july 11,2014 at 3:35 pm...

Earlier this year, Intel announced that it would bring two new enthusiast overclocking processors to market — the Core i7-4790K (Devil’s Canyon) at the top end, and the low-end Pentium G3258. We’ve reviewed theCore i7-4790K recently, and found it wanting; the chip’s overclocking performance is only slightly higher than the Core i7-4770K’s, even if its thermals are much better — but the dual-core Pentium G3258 had more potential. With fewer cores under the heat spreader, there’s less of a chance of a hot spot choking the die’s performance.

According to the Tech Report, the G3258 has exactly the kind of legs that folks were hoping for. The chip proved capable of pushing from its 3.2GHz stock speed all the way to 4.8GHz with a final temperature of just 64C. That’s a 50% clock boost — not bad for a chip with a retail price of $72 (TR snagged it for $60 on sale).

Single-Thread superiority

One of the topics that comes up with great regularity in CPU reviews is whether or not single-thread performance remains important in the modern age. It’s not uncommon for an AMD fan to show up and declare that no, thanks to multi-threading and HSA, single-thread performance is utterly dead (or will be in the near future). There’s no doubt that multi-threading can provide a significant performance boost in many applications — indeed, in some tests, AMD remains competitive for precisely this reason.

What people forget, however, is that adding more threads only improves performance from your single-threaded baseline. In several of the applications TR tests, the Pentium G3258 punches far above its weight-class, beating past the quad-core AMD processors when both solutions are overclocked. In Crysis 3, this situation persisted — not only did the G3258 outperform the FX-8350 when overclocked to 4.8GHz, it nearly kept pace with Intel’s entire stable of Core i7 processors.

What’s most interesting for gaming is how the G3258 spends far less time above 33.3ms than any AMD solution, even the FX-8350 — and what an enormous difference the overclocking makes. Clearly, the chip’s high clock speed is compensating for its low core count — improving the clock speed by 50% cuts its time spent above 33.3ms by a factor of five. It’s not clear why this is happening — presumably, the dual-core CPU is running fast enough to handle multiple threads without a major performance penalty. If CryTek targeted a relatively low performance threshold (say, four Intel cores clocked at 2.4GHz), that would explain the difference.

The G3258 isn’t going to be a chip for everyone. While TR has promised a more thorough investigation, there are obviously going to be multi-threaded titles and applications where more cores trump higher clock speeds, particularly since both AMD and Intel have chips with eight threads on the market. AMD may also have a new core of its own available in the not-too-distant future — the current $99 option is the Athlon X4 750K, a Trinity-based chip from 2012.

If the G3258 keeps hitting these clocks, however, it has a real chance of cementing its status as a great budget option. Fast dual cores aren’t going to be an ideal match for every workload — but for $72? That’s a pretty sweet deal.

IBM plows and ‘post-silicon’ computer technology...

IBM plows $3 billion into 7nm chip research and ‘post-silicon’ computer technology......

by usama.asif on july 11,2014 at 4:35 pm...

IBM has announced that it’s plowing $3 billion into two R&D programs that will hopefully make it the authority on 7-nanometer-and-beyond chip technologies. One R&D project will look at pushing conventional silicon chips as far as they will go (around 7nm), and the other will be tasked with finding new materials and techniques that can take us even further (quantum computing, carbon nanotubes, graphene, III-V). IBM also took the opportunity to remind everyone that it’s already the biggest player in 7nm-and-beyond technology, with over 500 applicable patents (more than double the nearest competitor). While most major chip makers (Intel, TSMC, GloFo, IBM) seem confident that they can take standard silicon CMOS chips down to 10nm, they are a little bit nervous about the prospect of 7nm and beyond. At around 7nm, the current building blocks of silicon transistors just won’t behave in the same way; when the gate is just a few atoms across, classical physics goes out the door and quantum physics (which behaves rather differently) takes over. While different transistor designs (such as 3D) allow us to take silicon a little further, the laws of physics will eventually catch up.

An IBM Research 3D chip stack (concept). It is alternate approaches like this, rather than brute-forcing smaller transistors, that are the likely future of computer.

serious effort to actually get silicon down to 7nm — and more importantly, to develop processes that can make 14nm, 10nm, and 7nm chips economically. As we covered last month, making silicon transistors smaller isn’t inherently all that difficult — but doing it without breaking the bank on expensive equipment is. IBM wants to develop new tools and techniques that will help silicon scale down to 7nm, and potentially beyond.

The second approach is potentially more exciting, at least as far as ExtremeTech is concerned. Rather than pushing silicon indefinitely, this second research project will look at other materials and techniques that might more easily take us to 7nm and beyond. Materials such as III-V semiconductors (notably gallium arsenide, GaAs) have around 10 times the electron mobility of silicon, allowing for smaller transistors with much higher performance and lower power consumption. Likewise, IBM is looking into graphene and carbon nanotubes, both of which have incredibly high electron mobility and can (theoretically) be fashioned into very small structures. IBM has already created a carbon nanotube transistor with a 10nm channel that showed no sign of performance degradation due to its diminutive size (CNTs are just single layers of carbon/graphene rolled up into a tube, and are thus very, very small).

Seb at IBM Research, checking out one of IBM’s cryogenically cooled quantum computers. “Whoa. Cool.”

But beyond better materials and the ever-shrinking transistor, IBM is also looking into different methods of computation entirely, such as neuromorphic computing (brain-like chips), quantum computing, and silicon photonics/optoelectronics (optical tech built into electronic chips). These methods won’t necessarily provide more gigahertz or consume less power, but they could offer wildly more capable computers that can process much more data than a conventional computer in the same amount of time. Finally, it’s important to note that IBM is already working on all of these technologies, and in many cases has been for years. The announcement of an additional $3 billion in expenditure is exciting, but it’s pennies in the grand scheme of computing R&D. IBM already spends roughly $6 billion per year on R&D, and companies like Intel, Samsung, HP, Microsoft, and Google are all around that mark. I would be surprised if IBM wasn’t already spending billions per year on the materials and techniques outlined in this story. Ultimately, this announcement feels like an exercise in marketing to reassure both customers and stock holders that IBM still very much wants to be a leader in bleeding-edge computing.
