Scientists Twist Radio Beams To Send Data At 32 Gigabits Per Second

labnet Re:Polarization modulation. (122 comments)

It's still modulation, modulation creates sidebands, and sidebands require bandwidth.

Nothing has changed, the Shannon–Hartley theorem still rules.

It's not modulation, it's multiplexing using a constant angular momentum. Modulation requires a change in something. With this case the they are sending seperate radio streams using different but constant rotated angluar momentums.
Think of it like 3D glasses in movie cinema that use right and left hand polarised light.

Smartphone Kill Switch, Consumer Boon Or Way For Government To Brick Your Phone?

labnet IMEI Blocking in Australia (299 comments)

In OZ, the carriers block at the IMEI level, so if a phone is stolen you can't use it in Australia (unless you can change the IMEI to one that the carriers recognise as valid)

Toxic Algae Threatens Florida's Gulf Coast

labnet Synthetic Grass (99 comments)

One reason I turfed my backyard with artificial turf.
I was sick of weeds, animals digging in it, mowing it, fertilizing it, the kids trampoline killing it.

Synthetic grass can now look as good as the real deal. It can get hot in summer, but otherwise its nice having an always perfect looking lawn.

Ask Slashdot: Can Tech Help Monitor or Mitigate a Mine-Flooded Ecosystem?

labnet Knee Jerk (123 comments)

NO mine wants a tailings dam to collapse. There are regular conferences on how to design the things and specialists who design them. NO CEO wants this to happen, because the cost reparations is horrendous, and contrary to what the comments have been like here, the bosses of these companies (well the ones I've know of) want to be good corporate citizens.
Mining has risks, and incidents like this will ne analysed and fed back into the future design models, and like all things in life, will improve over time.

Hack an Oscilloscope, Get a DMCA Take-Down Notice From Tektronix

labnet Tek smeck (273 comments)

Have never like tek scopes that much, or Agilent. In fact my fav. Scopes are Yokogawa DLM series.
All the manufacturers do the cripple thing though. If you want free I2C or LIN or CAN or USB or UART, buy a PC scope like a CleverScope.

Why Morgan Stanley Is Betting That Tesla Will Kill Your Power Company

labnet Re:Wouldn't electric cars have the opposite effect (502 comments)

To add to what you said.
Australians now pay about 25c/kwh compared with 12c/kwh 10 years ago.
The overinvestment in wires and poles was due to stupid legislation that GAURUNTEED a 10% return on any capital investment. (Gee lets spend a billion so we gaurunteed to make $100M)
We put 40kwh of solar in at our business that with the current subsidies nets us 18% return on capital (vs 2% cash in the back)

35% of American Adults Have Debt 'In Collections'

labnet Re:I'm probably one of them (570 comments)

I had a debt collection agency come after our business for $100 unpaid cell phone bill.
It was from a lone disused cell phone where we had either never received the invoice or admin had misplaced it.
I said no problems, just give me a copy of the invoice and we'll pay up.
They said. Can't do that.
To cut a long story short, the phone company sells anything past due date to a collection agency BUT doesn't bother to give them the supporting documentation.
How retarded is that!

A Router-Based Dev Board That Isn't a Router

labnet IoT which chipsets? (54 comments)

We are about to embark on designing a similar product. Essentially we want a gateway that can select from either a Cell Phone embeded data modem such as the Telit HE910, or local WiFi, then provide an internal data link via USB or Ethernet to our device and some remote connectivity for setup via Bluetooth.
We need good power management, and the ability to add local peripherals (such as a keypad, status LEDs, etc)
OpenWRT looks like the right foundation, but which chipset to select is more difficult.
Any suggestions from hardware devs out there?

States That Raised Minimum Wage See No Slow-Down In Job Growth

labnet Re:by extrapolation (778 comments)

Australia has a minimum wage of around $20/hr and we are a very prosperous country.
Higher wages just take profits from the mega corps and give it to the working poor who , shock horror, spend it, and create more wealth!

NYC Loses Appeal To Ban Large Sugary Drinks

labnet Re:Praise the Courts (532 comments)

. What a person does with their own body is not the government's business.

Well it does matter in the rest of the developed world that has socialised health care systems.

For example. Smoking in Australia, although not banned, is now incredibly invonvenient. The goverment banned all advertising; smoking in workplaces, all public enclosed spaces, outdoor eating places, street malls; jacked the price up to $20 a packet; hid the packets under counters; removed all branding from the packets themselves. Why? because the government (ie the tax payer, ie me) bears the burden of providing their health care. The same can be argued for huge serviving of HFCS drinks.

The trick is striking a balance between restricting an activity that reduces your lifespan and costs society $$ vs the individuals freedom.

Half of Germany's Power Supplied By Solar, Briefly

labnet Re:Gigawatts per hour (461 comments)

I'm suprised it took this far down the comments for such a basic mistake to be corrected.
For clarity these are correct ways to refer to power produced.

20GWh was produced over a one hour period.
The solar output peaked at 20GW.

Energy is measured in joules which is watts x seconds.
Power is measured in Watts which is volts x amps.
(yes there are other definitions, but this is in context)

Latin America Exhausts IPv4 Addresses

Why did they have to make the number more than atoms of the universe when they could have just turned the ipv4 from 8 to 16 bits.

Bzzzt.
Evolution is the creation of new information through genetic mutation.
Natural selection is the killing off of non optimal life forms.

Iron Nanospheres Turn Plants Into Plastics

labnet labnet writes  |  more than 2 years ago

labnet (457441) writes "A new type of catalyst made of iron nanoparticles enables the efficient conversion of non-food plant waste into the key components of materials such as plastics, medicines, and paint. The catalyst was developed by chemists at Utrecht University in The Netherlands, together with Dow Chemical's Benelux operation and Delft University of Technology."

Single ion clock 100 times more accurate than atomic clock

labnet labnet writes  |  more than 2 years ago

labnet (457441) writes "From news.com.au :

University of New South Wales School of Physics professor Victor Flambaum has found a method of timekeeping nearly 100 times more accurate than the best atomic clocks. By using the orbit of a neutron around an atomic nucleus he says the system stays accurate to within 1/20th of a second over billions of years. Although perhaps not for daily use, the technology could prove valuable in science experiments where chronological accuracy is paramount, Prof Flambaum said.

Now a Ronald Bormaster is claiming "a patent application for an inventory-control system using radio frequency identification".. including things like livestock (which in many countries has been used to inventory animals since last century). He is now suing Wal-Mart, Gillette, Michelin, Home Depot, Target and Pfizer."
