Recovery not necessary
You can't radio-control through water (well, you can. But that's the rule-of-thumb). So it's going to be an autonomous drone. This means it'll have smarts on-board that can look at the world around it, identify vessels, etc.
So Drone pops up, scans the surrounding area then compresses the data as far as possible before dropping to the sea surface. It can then use an acoustic modem to send the data to the sub without giving away the sub's position too exactly (some of those modems have a 7km range (so if you see the drone you only know the sub is somewhere in a >21sqkm circle), and I'd be surprised if the hydrophones on a sub couldn't top that for receive-only functions).
The drone could then turn into a Slocum-style glider AUV (flooded body so as to kill the electronics, air-filled pouches in the wings for buoyancy, wax-pouch hidden somewhere in the body) to get itself away from the Transmission zone (further obfuscating the position if the sub) without needing any batteries.
It's subsea but orders of magnitude faster and with kilometer ranges. It also deals with all the noise and interference you get subset- and with a few-km range that's a LOT of noise.
Getting it working in air is impressive but I wouldn't imagine ground-breaking. Just good old-fashioned engineering-around-a-problem.
It's in the article. 2 characters per second. So 1Mbyte would be 500,000 seconds, or a hair over 5 days.
Subsea acoustic couplers hit nearer 6k/s, so there's a lot of room for improvement and if the researchers passed the data through desk/floor/desk they could have a much better, though more environment-dependent, coupling. So there's scope to drop this transfer time or increase it's range.
And a PIN number is 4 numbers, between 0000 and 9999 so could fit into 2 bytes with plenty room to spare.
Wireless optical data transfer?
That'd be IRDA, then. It was on more or less every smartphone I owned before 2007, and my current one too. Long may it continue.
IRDA has a Gigabit spec too, according to Wiki!
So NSA officials say it's not illegal?
That's fine by me then, no conflict of interest there at all. Nosireebob.
Re: DMZ and firewalled to hell
You'd put sensors like that in the DMZ so that they're outside your network. To see anything happening on your network it'd have to pass through the firewall.
So something in the DMZ is firewalled off from your private network, though still able to connect to the Internet to provide services and call back to it's masters.
Re: Off-topic: Electric cars?!?
Please tell me this is a Troll. If not:
Nuclear Fission power stations would make your car Nuclear Fission powered, not Nuclear Fusion powered.
90% of electricity doesn't come from Coal, at least not in the UK or probably any other developed country.
We ARE developing hydrogen powered cars. Unfortunately you're talking about a fuel with a tiny volumetric energy density unless it's pressurised- it needs to be something like 300bar (4500PSI) before it's anywhere near as good as petrol. That means a heavy containment vessel or an enormous explosion in a crash- not a burn like with petrol but a proper Hollywood explosion. And a big crater. Then there's embrittlement of various materials as the hydrogen screws with them- so you need to be vey careful with the materials you use at all points. And then you need to go through the whole process again for the rest of the fuel-handling system and anything that could come in contact with it if/when vented. And THEN, after all this you need to make it production-line ready and able to last 20 years.
Then there's the production of hydrogen and the development of a pipeline network to carrry it all- given the extra wall-thickness required for a pressurised hydrogen tanker over a petrol tanker they're pretty impractical for carrying the volumes of fuel that currently criss cross the country. Producing the Hydrogen would require a phenomenal amount of power, too- and if memory serves is less currently efficient than an internal combustion engine anyway when producing it from water. Which is why most Hydrogen now comes from natural gas. So even your Hydrogen cars derive their energy from fossil fuels, by way of harnessing power stored in other fossil fuels.
So THAT'S why we're not using Hydrogen-powered cars. Because they're a monumental engineering challenge to build and still, currently, have a dependency on fossil fuels. In future this may change, but at the moment their development into a practical /mass-produced/ product is a good way away.

Another sign that we are officially in the future
People will stay at home with the heating on to avoid this, creating more of this mess. So the more there is, the more will be produced.
So we've got a more-or-less self-perpetuating nanoscale grey goo that is killing all humans exposed to it? Just about the time we got computers smart enough to legally drive a car while talking over a globally-reaching, near-instant web of almost all the world's information.
At the same time, Evil Corporations and The Government are slurping up our comms.
I feel I should have my local library move lots of its 'Science Fiction' section to 'Recent History'.
Re: i wonder....
Unfortunately yes it would short out at any significant voltage- the electric would just arc through it to the water. Might work with low-voltage PCBs, but then there are already waterproofing agents for those.
When electronics are to be put under water, though, they're typically either put in a 'dry' housing or in an oil-filled container of some sort. A 'dry' housing means they can be kept in any environment you want (typically sea-level pressures with regular air) but is expensive. Oil-filled boxes are cheap but mean the electronics see the full pressure of the water (so you either have a pretty limited depth before things break (up to 50m is generally possible with regular 'home' electronics that don't include electrolytic caps) or have to modify the electronics to remove 'crushable' components like crystals).
An 'oil-filled and compensated' 3-phase motor could hit the bottom of the Challenger Deep and still work fine as it's just a block of metal with another block of metal inside it, with the void filled with oil and so is more or less incompressible.
The body of the Lotus, however, would have to be foot-thick Titanium to keep the driver safe from the pressure (at that depth, about 32,000psi!)!
It could almost pass for human
With the right footwear, an inconspicuous waterproof covering and a mobile, self-propelling human-rideable vehicle that can act as a local power generator / comms hub when it stops travelling.

Re: Automated till hell ...
I believe the bagging area is used as a sort of Checksum, so if you scan something that is supposed to weigh 500g and it weighs 2kg you've clearly got the wrong thing and are trying to pass off a 2ltr bottle of coke as a half-litre.

Re: Battery life
They already did that. It's called Petrol. Or Diesel. Or jet fuel*. Or external combustion. Or CNG. Or, if you're really desperate for range, nuclear!
If you like your explosions huge and frequent and spares costly, Hydrogen could do a decent job as well.
Basically, there are a LOT of options for longer-range / lower-cost vehicles already. Why try to shoehorn in a technology that doesn't work for it and isn't meant for it when there are plenty of decent alternatives?

Re: Wiimote :)
Absolutely. Did this years ago with a head-tracking eMagin Z800 headset.
Playing Oblivion with a Wii Balance Board for motion (so you're skateboarding around town :)), Wiimote + Nunchuck for left/right arm (or even pull-back w/button pressed to notch an arrow, release to fire). And head-tracking so you always look where you're... well, where you're looking.
The only serious problem was that you couldn't look and aim independently. Which should be pretty simple to sort in an all-3D game (so anything from Quake onwards).
Another little issue was that I needed to have a multibutton mouse to select which kit combination I was using, and remembering that in the middle of a battle was a PITA. But again, a software fix to output which weapons/shields/spells/etc are equipped over USB/serial/etc would sort this.
If the Rift can bring this sort of tech into the proper mainstream, good for it! I'll certainly be buying one :D

Re: Duck test = fish test!
That would have been the best defence ever!
"But your Honour, BitCoins do not float on water and are therefore nothing like a duck. Moreover, by your reasoning a Duck can be both made of wood (as it floats) and therefore a Witch (which burns as does the wood you CLAIM ducks and bitcoins are made from)- a similar line of reasoning which lead to the death of an innocent civilian documented by the respected group the Pythons.
Your Honour, do you REALLY want to declare that a BitCoin is equivalent to a duck when it is well established that such actions can lead to the death of innocents?"
Re: Having our cake and eating it too
Ah yes, but think of it from Apple's point of view.
If you're a Megacorp who orders laptops in by the million, it makes a lot of sense to buy them all as one company- you have one account to administer, your delivery addresses can be changed to reflect market conditions (so if they sell well in Lisbon but not in London, part of London's allotment could be shipped to Lisbon instead), and you have more bargaining power as a single million-unit customer rather than 1,000 thousand unit entities arranged around the world.
Plus with a single purchasing company you only have one pair of international contract laws to abide by with regards to your supply (i.e. you just need US/Chinese lawyers for supply rather than US/Chinese, UK/Chinese, Europe/Chinese, Japanese/Chinese, etc).
So it DOES make good business sense even if you're not trying to save tax.
The dahls were good, then became the Daleks who... weren't.
The Daleks are bonded polycarbide transport machines containing the mutated remains of a species called the Kaleds. The Kaleds were at war with the Thals- they had a dirty nuclear war. This lead to mutations, and these mutation were accelerated and guided by their chief scientist Davros. The mutated remains were placed in a metal war machine- that's how the Daleks came about
They had a bigass war with the Time Lords for control over Time itself, which eventually both sides lost. A single Dalek command ship containing an/the Emperor Dalek survived, falling through time and started rebuilding. And was then wiped out by Billie Piper using finger-clicking magic, possibly derived from her days as a pop singer.
Since that fateful Saturday evening, the Daleks have existed entirely without testicles.
Not quite, but Blackberry and iPhone both run through a single supplier and are both pretty well tied-in to the US.
It'd be a LOT easier to foster a relationship with Apple and RIM on this front than with HTC, Samsung AND Nokia- the major Android suppliers, none of whom are even based on the same landmass as the FBI- and would be far less risky than getting Google to build it into their base Android build (it's relatively-open-source so it could be found and exposed, or just expunged as 'malware').
On a personal note, I'd just like to cry "Down With This Sort Of Thing!". As telecoms data is available from the infrastructure suppliers (who will also provide convenient wiretapping systems), and they apparently don't use this approach with those sufficiently tech-savvy to be encrypting data properly prior to transmission (or if they do it's just for the transmission, with the data stored unencrypted elsewhere), this is clearly just a way of circumventing the requirements for a wiretap warrant. If they wanted to capture data BEFORE it was transmitted over the internet (passwords etc), that'd be a much more reasonable use-case.
I'd also like to ask why permission for the modification of a suspect's property- especially when this requires equipment that is otherwise very much illegal and may cause the suspect- is easier to come by than tapping into comms they're freely blasting out over a wire.
If they can print a transistor they can print a diode... Which can be made to emit light. With a grid of these you could then have a display built into your skin. It'd then take only a little extra work to incorporate a touch sensor into the system.
With strain gauges built in, again pretty simple, you could have the image re-map dynamically to show a flat image.
lots of potential in this invention!
Clearly it was the departure of Mondas
When the populace of Mondas determined that their planet was dying, they launched a big-ass rocket to bring their population to Earth. This pushed so hard it knocked their planet out of solar orbit and caused no end of problems for the remaining populace, which they helped fix by building a really big vacuum cleaner and sucking away the nacent Mars' atmosphere. The 'spare' atmosphere was used as propellant in a planetary ion-drive.
This, being based on a shocking ignorance of even Science-Fiction level physics, is still more believable than some of the 'theories' being presented here.
Re: How about buoyant elevators?
Pipes of man-carrying diameters carry oil and gas across continent-spanning lengths and at pressures an order of magnitude higher than those you'd see in a 1km water column (which would top out at about 1500psi). This would be a larger pipe, but pipe can be made at any diameter you want.
With a 2mx2m-face elevator, on the ground floor you'd have about 42MegaNewtons total force pressing the lift against whatever seal you chose, and with that sort of pressure you could just use a metal-to-metal seal rather than an easily-damaged rubber one. You'd actually have to design it to NOT seal as well as possible!
Also, modern skyscrapers get rid of some of the problems of air-columns by using revolving doors (essentially they're permanently sealed). A similar arrangement could be used to keep a few per-floor segments decoupled. So you've got a number of 2-floor or 10-floor sections of pressure to worry about rather than a whole 1km long water column.
You'd have a minimum of 3 doors, 1 on the car and 2 on the building. The car would dock with the wall of the lift shaft and the first building door would open, venting the excess water and either pumping it back up to the roof or just venting it to the drains. The doors of the building and car with people behind them would then open, allowing (dis)embarkation. The people-protecting doors close, the building's "inner" door closes, and the space between the car and building inner doors would then be flooded with water, removing the sealing pressure and releasing the car.
I wouldn't bother with any ropes- they'll get wrapped up together. Buoyancy control will provide an appropriate way to control up/down motion with electric thrusters or something else providing lateral movement to get it close to the door (using the idea of one or two transit shafts with the doors arranged between them to allow for some quite efficient routing of multiple cars).
This also provides the added benefit of being incredibly safe in a fire- you're in a water-filled tank that would take a near-impossible amount of heat to heat by more than a few degrees and it can vent the lifting fluid to calm any fires. If it fails you could drain it and recover anyone trapped inside.
Maintenance would be simple with underwater ROVs and AUVs. Divers couldn't stand 1km pressures.
You could wrap it around buildings- say, a double-helix of lift transit shafts with cross-members where the lifts can change passengers. It could even be designed so that in the event of a fire the shafts could be drained, the pumps turned to minimum and you've got a kilometer-long waterslide to the ground floor.
Install a few radiator platforms going down the side and you could keep the water very cool, saving a lot of money on air conditioning.
With a lack of lifting rope (and some underslung buoyancy), you'd be able to have it buoy up to the roof without unsightly roof constructions.
And just THINK how extravagant a water-filled tower would look in the desert of Dubai. The tallest tower, FILLED with the rarest resource.
I'm just off to design this thing. There's got to be some rich git out there who wants the tallest tower with the biggest, baddest-ass lift.
Re: MS Security Fails - Eadon the BlueHat bonus winner
Most of that is clearly utter shit, but just so you're aware of one point the UI of Windows ISN'T part of the Kernel. It's part of the program that provides your post-file-manager 'Windows Explorer' views. And can, very easily, be changed.
Documents aren't started automatically, and haven't been for ages (assuming you're meaning Macros and VBA code), unless the user specifically asks for it. In fact any version of Office since word 6 was on the go (so just before you were born) has this security built in and turned on.
USB sticks were a fuckup but this was sorted a few years ago. They even rolled out a fix to customers running still-supported MS OSes.
Users still click 'YES' or enter their root password under Linux. It's the /mentality/ that's wrong rather than the software.
I have no idea what the fuck you're on about with 'don't execute arbitrary code'.
What's wrong with making executables EXE files? If anything this makes it EASIER to spot potential malware for your average user- if something ends in ".doc.exe" it's a virus and you delete it immediately. That also means that email can easily be removed as a way of blocking executables except where the user has renamed it to a non-executable extension (so there is a definite user action to change it back and then run it, so it's likely one they know the source and content of).
The layers thing is bullshit of the lowest order. Alternatively I've missed something, so please enlighten me.
'Don't bundle IE' Fair point, but isn't it more or less as secure as Chrome or Firefox now with most vulns coming from plugins?
Hiding file extensions is indeed a retarded idea as it gets rid of the security benefits of being able to see what the file will do. I can't believe I'm agreeing with Eadon on that one. Saying that, you've negated your argument about the executables thing so it's still a MASSIVVEE EEADON FAILL LOLLORZ
Separate Data from System... in what way? They already do keep your documents separate from your program files separate from your OS files.
Don't support Win32?! That would remove support for 30 years of applications and relegate it to a Linux-level of program availability. Which, while perfectly useable, doesn't have 'the real thing' in a lot of cases. Shout all you like about LibreOffice but it's still trying to get to where MS Office was 10 years ago.
You know what, I can't be arsed answering any more of these points. Please get off the side of Linux, Eadon- you're stopping people from changing over.
How about buoyant elevators?
It is well within our powers to make a pipe that'll survive the 1500psi or so that a water-filled body would have exerted on it's lower end if it was a kilometer long. So build a very large diameter pipe and flood it. Fill a buoyancy tank at the bottom end to rise and vent it to descend.
You now have an elevator system that can, for the energy price of a small ground-mounted air pump and something to pour rainwater into the shaft to replace any small losses, lift massive weights thanks to the buoyancy of air in water. It also becomes simple enough to route multiple cars around one another and if a car fails it won't drop people to their doom, though you'd want a lower end of the shaft that would correctly orient the car to have it mate with an emergency exit.
Breathing could pose a problem unless you had tanked-in oxygen and/or fill-up points. Or had it rise fast enough that you didn't need to worry about it and could pump in more fresh air whenever you docked with a floor.
This isn't like SCUBA or SAT diving; each car would be a pressure chamber so you'd have no problems with regards to the Bends as there'd be no pressure change acting on the passengers.

They were reading freely provided, unencrypted transmissions on unregulated frequencies that anyone walking past could have read as well. I still fail to see what was wrong with that legally.
You do not have a reasonable expectation of privacy if you are shouting your details out of your front door.
If they had cracked a single packet of encrypted data, though, they would have been hung up to dry. But they didn't, or at least no evidence was uncovered, so nothing bad happened.
That better be augmented by some serious differential positioning; having my beer delivered to within 5m of me is likely to result in about 100 people getting to it before me...
The net-on-a-pole solution sounds good, though- with a QR code or similar tagging the top the GPS can guide it in and a camera can then position it perfectly to drop the beer.
Using a system like an oilrig escape chute would help it land safely, though a little shaken. Or a funnel-shaped net.

Re: Eric, fixed that for you:
In his defence, Google Streetview goes round once every few years- I think they just started their first update after however many years its been up- and captures maybe a dozen frames of anywhere near your house and all within a minute or so. They also take images down if you raise privacy concerns.
A drone, or collection of drones, could provide 24-hour live coverage of your house. That is substantially more intrusive and targetted- a whole other ball game to Streetview.
I'm not sure if Streetview is creepy or not, but having a drone watching me would be far, far unnerving than me appearing in a photo on Streetview.

Re: "i said it all a million times,."
I think I see where you're coming from, but it's utterly wrong. You've seen a 2MW generator and thought "hey, if I spin that shaft I'll get 2MW!" then thought "Hey, you know what spins really well? An electric motor."
Unfortunately the electric motor will have to put more than 2MW of power into the dynamo to get 2MW of power from it. This is because as you spin the rotor of the dynamo the resistance to movement builds up more and more; spinning the dynamo shaft inside the coils of the dynamo creates a magnetic field which acts against the motor you're using to drive the dynamo shaft. You can't get rid of this field; it is this magnetic field growing and collapsing that pushes the electrons through the wire and so creates an electrical current.The faster you spin it the more resistance there is.
If you think you can do it, build a smaller model. Even a model that produces no excess power but spins itself forever would be worth approximately all of the money in the world. You would become an overnight billionaire, worth substantially more than the oil companies who'd really not like you (but to whom you would pose little immediate threat). Maplin or RS (or even eBay!) would be able to provide you with an appropriate motor, dynamo and other components to give it a go.
Re: Graham Bartlett
You can't arrest a bot.
However, that bot is run by a department in a company. That department has a head, and he can pass the buck to the CEO of the company.
If MS provided the filters it may be possible for the CEO to pass the buck to MS. And then some upper-middle-management type ends up in prison for a while. Or maybe they'll see their chance and kick Ballamer behind bars, allowing them to get on with improving as a company.
If MS didn't provide the filters for the company, then the bot-operators are at fault and need to figure out who to point the police towards, i.e. who was responsible for the Bot at the time the offence was committed.
