They plan to power a dogtag sized Bluetooth device by harvesting typical WiFi signal power.

The antenna will be at most about half an inch on each side (0.0125 meters, for a total area of 0.00015625 square meters.
Near a wireless network station used in homes and offices, the field intensity is typically below 0.5 mW per square meter.
Further upthread, someone posted the power required by a modern, low power Bluetooth chip, in its lowest powered sleep mode it requires a current of 900nA and 1mA when idle. Let's say it operates on 1 volt (it's probably 1.2v) so we will actually underestimate its power requirements by saying in its lowest powered sleep mode it requires only 900nW (that's 0.0000009 watts).
At 0.5mW (or 0.005 watts) per sq. m, the maximum energy a dogtag sized device, assuming 100% efficiency (not possible) will be able to harvest is 0.005 * 0.00015625 watts of power. This will work out to about 780nW.
780nW is less than 900nW. QED.

And that's giving them the benefit of the doubt (100% power efficiency, and a lower working voltage for the Bluetooth chip that it probably uses, and only considering the chip being in sleep mode, its lowest possible power mode, and not considering at all any other circuits the device will need - it will need more than just a bluetooth module, it'll need at least a minimal microcontroller of some sort).

I'd change browsers if there was something to change to

There's Seamonkey, and there's Pale Moon. Make the effort to switch. Vote with your feet; it's the only possible way to force Firefox to actually start listening to users.

But the employee who found her wallet missing from her purse was certainly happy for the camera.

Women have wallets inside their purses??

Your name wouldn't happen to be BOFH, would it?

Mozilla doesn't build hardware. We make software

Really? I thought YOU fucked up user interfaces.

How many times, though, so people complain about a Youtubs vid or a BBC article having comments disabled? I like the idea of a "fuck you, we're discussing this anyway" service.

How little stuff has actually changed.

The image of the very first Computerworld, the first page has a story about a patent lawsuit.

It's a Hardley Rideable, not a bike!

You'd not want a hub motor because it increases unsprung weight which has an adverse effect on handling. Same with electric cars - Tesla for instance doesn't use hub motors but the traction motor for the Model S is attached to the structure of the body.

Then again, we are talking about a Hardly Rideable rather than a motorcycle...

Well, if anything organized enough to convey information implies that an intelligence was behind it, who created God? Who created the creator of God? Who created the creator of the creator of God? And the creator of the creator of the creator?

Other humans and living creatures have given me far more comfort after losing a loved one than a mythical being ever can.

If I knew I was gonna get marked down 30% for not being a minority, I'd just say I was gay. Discrimination of any kind, yes even "positive", is fucking retarded. I really hate it.

Huh? 10% faster is 1000 times faster? How do those mathematics work?

Sure, if you're getting an off-the-shelf board or a board designed by someone else.

However, I will note that the Xilinx Spartan 6 user manual has about half a dozen pages devoted to how to lay out the PCB *for the configuration clock signal alone*.
