While the idea of using LED's broadcasting around the room (IR or visible) should be fine, the idea of using the white LEDs lighting the room isn't. The bottom line is that while the driver LED itself can be modulated at high speed, the photoluminescent phosphors generally cannot. The commonly used photoluminescent phosphors have characteristic exponential decay times of microseconds to milliseconds, depending on the exact phosphor. The most common phosphor in white LEDs, YAG:Ce3+, does have a pretty short persistence time of around 0.1microseconds. So maybe one could get data rates as high as a megabit per second, but that would be about it. But remember, the efficiency of white LED bulbs depends crucially on the phosphors chosen - so choosing ones for data transmission could easily negate any energy efficiency advantages of white LEDs over, say, CFL's.
Re: I use KeePass
My experience has been that the places I worked that had frequent forced password changes were in fact the places it was easiest to login as my boss. Why? Because by requiring frequent password changes, people start writing their passwords on post-it notes and hiding them in very predictable places. Requiring a password change once a year, and allowing full pass phrases so people can use complete sentences, IMO is the best compromise.

AT&T + Apple: What a pair of shmucks
The ex-AT&T VP they interviewed in the program was very clear the driver was the rollout of the iPhone. So you have Apple on one end insulating itself from the working conditions of those making the phones, and their original partner AT&T insulating itself on the extreme other end of the connection from those who have to climb the towers. I hope all those Apple fanbois are proud.
Re: Even though I disliked Boy Wonder...
Having lived and worked in the area, I have to wonder about the traffic and employee parking. A typical parking lot design guide for office space is as follows:
"Related to Personnel: 1 space per 1 ½ plant employees + 1 space per managerial employee + 1 space per 10 managerial employees for visitors.
Related to Floor Area: 1 space per 1,000 sq. ft. of gross floor area for warehousing and distribution. Or 2 spaces per 1,000 sq. ft. of gross floor area used for manufacturing. Or 2.5 spaces per 1,000 sq. ft. of office area."

I don't think we've had galley slaves since around the mid-1700's (Henry IV of France).
Great to see them make a comeback!
Re: I'm guessing Nokia saw the HTC One
As the article states quite clearly, Nokia is quite happy to license it's patents all over the place. So the issue isn't that Nokia has a problem with RIM, ViewSonic & HTC using it's inventions, The problem is using them without paying.
Too bad no one can give Facebook an ethics transplant.
Every attempt has resulted in rejection.
"...ensuring British citizens are whisked off to cloud-cuckoo land to be buried in some desert for a few years..."
I'm not aware of any British hackers who have been successfully extradited to the US. McKinnon, for example, is still in Britain. Seems if anything, the "lopsided-extradition treaty" is lopsided towards the citizen being extradited, as it should be.
Re: Cleanup costs
I agree. $200k amounts to about 8-10 man-months of work (counting salary, fringe, overhead, and G&A) at a typical Silicon Valley company. And the "work" is mostly trying to figure out what he actually did, not "repairing damage". It's a surprise the number is that low.

Re: The USPTO
Q: Do these guys actually check whether they issue almost identical patents multiple times?
A: Apparently not. The USPTO has issued patents for using laser pointers as cat toys at least 5 times:
5443036 Method of exercising a cat
6505576 Pet Toy
6557495 Laser Pet Toy
6651591 Automatic laser pet toy and exerciser
6701872 Method and apparatus for automatically exercising a curious animal
One has to wonder
If Bit9 has sold it's products to Iran yet.
"But with the IPA Twitter has said it wants to put control of patents back into the hands of people who dreamed them up..."
Yea, but Twitter will keep the money. BFD.

Re: What no iMilitary
One reason to pick Android is for transparency of the OS. That fact alone makes Android the only widely used phone OS suitable for creating a truly a secure phone. If you can't examine the OS at all levels, you can't hope to try to insure it's security.
Kind of baffling to me that the Cannon D10 & D20 were not shown, give they are pretty popular ruggedized waterproof cameras. I've had a Cannon D10 for several years now, and I use it almost exclusively in the water when swimming for underwater & "out in the middle of the pond" shots, not just "near" water/snow. Works great, floats if let go (even in fresh water), great pictures, etc. They are also very brightly colored, specifically so they are easy to spot if you set them down.
have resulted in 30 of Eddy County's dogs, cats, and sheep needing to be euthanized.
Can't speak for the sheep, but unless the "euthanized sheep count of Eddy County" was about 30, it says more about Eddy County's lack of enforcement of rabies vaccination laws than anything else.
Rabies vaccination is very effective. In the US, all veterinarians are required to be vaccinated against rabies.
For other reasons, I am immunized against rabies. It helps dealing with my boss.
That's been my experience too. For years I've been using the old Netgear XE102 powerline adapters (14Mbps) for stuff whose speed I don't care about, like my Tivo updating it's schedule. But I've found the placement of the units is very sensitive to where the surge protectors are relative to the powerline adapters. The surge protectors look like a low impedance across the mains up at the RF carrier frequencies these things use. I've noticed my XE104's (85Mbps) to be even more sensitive than the XE102's.
Dot com bubble all over again
I'm sure there's more to come in this next bubble. After all, there really hasn't been any reforms to the US financial system. The fact that this company has made such basic accounting blunders, both of which involved the company failing to account for its major expenses, does not bode well.
This is basically what Solyndra's core IP was about - 3d solar cells that collect the sunlight very efficiently regardless of the angle of the sun, rather than flat panels. Their preferred implementation was cylinders, but the patents cover this MIT structure.
In the end, the maximum solar flux is 1 kW per square meter, and nothing will change that.
Re: AndrueC: Dumb meters for dumb people
"What is the logic in replacing the meters so frequently? Lousy build quality?"
Maybe you should move to a less corrupt locale, where the politicians actually believe they serve the people who elected them...
I live in a State with very strong utility regulation and consumer protections. My understanding from talking to the gas company is that the requirement (for the gas meter) was a combination of safety and proof of meter calibration. The old meter gets refurbished and recalibrated, then is placed back into the pool of meters to go back into service. My water meter was replaced last year, and they claimed it was to insure calibration, and again the old meter gets refurbished and eventually placed back into service. I presume the electricity meter replacement has a similar rational.
I've no doubt that part of the periodic meter replacement is for the utilities protection. If nothing else, by replacing the meters every decade or half-decade, they can inspect the installation for tampering.
Re JC2: Dumb meters for dumb people
"...I've no idea what makes you pretend to know otherwise."
The fact that I've owned 3 houses over the last 20 years and all of their water, gas & electricity meters had RF transmitters for remote reading. That's 9:0. One house was in Massachusetts, one in Florida, and one in California. In most States, meters have to be replaced by the utilities every few years. Where I live now, gas meters are replaced every 5 years, water & electricity every 10 years.
The utilities have been switching to remote meter reading over the last decade or two is because one meter reader can read a huge number of meters compared to one who has to walk around people's yards.
Re: Dumb meters for dumb people
The most hilarious part of this issue is that most of the dumb meters in question already have radio transmitters. So do most gas meters and water meters. The "meter readers" just drive down the street and a RF scanner in the car reads the meters.

It's only a matter of time before someone figures out a way to do some imaging thing analogous to a buffer overflow so all your camera has to do is see the QR code, not even try to read it.
dirigible might be better
Some type of dirigible with station keeping propulsion (solar powered?) would probably be more reliable than an outright drone that requires it's propulsion system to be working in order to stay aloft.
Re: Anyone else getting tired..
See my post above. The allegations were true, as documented by Apple itself as well as The New York Times. What Mike Daisy lied about was his own experiences, most of which he fabricated.
Again, listed to the retraction and investigation of Mike Daisy:
For those who bothered to listen to the "This American Life" retraction of their Mike Daisy piece, the allegations about worker conditions at Foxconn were basically true, many documented by Apple itself as well as The New York Times. The thing Mike Daisy lied about which caused the retraction, and Daisy admitted to lying about, were his personal experiences. Most of what he originally claimed were first hand experiences in his theater piece were in fact fabrications based on what he had read about Foxconn's operations.
The the bottom line is that Foxconn would not sue anyway because the allegations are true, and many were in fact documented by Apple itself.
The retraction can be listened to here and takes about an hour. http://www.thisamericanlife.org/

Re: Dear Mozilla
Fix the damn Android version too, while you are at it. It sucks. It has basically zero user control of privacy, and most plugins to make up for it's poor security (ghostery, noscript, betterprivacy, etc) are not compatible with it.
Re: Non sequitur
The real issue, at least from a US legal viewpoint, is that Apple instigated a price fixing model for the eBook industry. That little bit about publishers couldn't set one price for it and then turn around and sell the book more cheaply to Apple's rivals. While that is not strictly price fixing (Apple will claim the publishers can drop the price for everyone), it still has the same effect of artificially raising prices and stifling price competition between different eBook sellers.
Websense's position is pretty hollow, since Websense isn't eligible to submit a proposal, unless Websense has suddenly become a Pakistani company. The RFP says "...the indigenous development..." & "This system would be indigenously developed within Pakistan...".

Re: Fighter to be flown by Cruise?
Geeze! The real problem with a Top Gun 2 featuring the F-35 is that an UAV fighter can out turn a manned aircraft because it does not have to limit the g-forces to levels a human can endure. Even back in the 70's, when I worked in Aerospace on fighter & missile system design, we all lamented how having a meat bag on board forced the plane us to cripple the planes performance from what the airframe limitations were. The "next big one" will show that manned fighters are like that scene in War Horse where the British Cavalry charge the German machine gun emplacement - stupid and anachronistic.
Re: This is what passes for testing?
Note the "testers" were mostly (if not all) Universities. I've yet to encounter any fresh University graduates (even PhD's) who didn't need on the job training on all aspects of professionalism, including how to write and analyze specifications, as well as how to scope out a project, etc.
While its not a panacea...

Re: Re: It's a trap!
AT&T are such scumbags, anything they are "for" means the customer is by definition being screwed. They can't help it.
AT&T is the perfect example of why if corporations (in the US) should have the same rights as real people, they should also be subject to jail time and the death penalty.
