Police Chief Teaches Parents To Keylog Kids

kindbud Install one on parent's computer too (505 comments)

The chief continued... "Because kids are smart they might suspect that their own PC is keylogged, and use another computer in the house to avoid being supervised properly. To avoid this I suggest installing keyloggers in all computers in the household. Now, parents I know are very busy and it is hard to keep up with all this tech, so to help you be a better parent, the department has setup a website where you can register your keylogger and upload its data to our servers, where department specialists will look for any red flags that need to be brought to your attention concerning your child's online activities. Once this program is more widely adopted by your child's friend's families, we will all be able to keep all our children safe online, no matter which computer they use."

How Watchmen Killed 'R'-rated Fantasy Movies

kindbud Barbarella? Heavy Metal? Why? (771 comments)

Maybe the studios are tiring of unimaginative attempts to fleece some money out of them for yet another forgettable remake of another forgotten film. I know I am.

Can anyone think of a reason to remake Barbarella or Heavy Metal that is more engaging and compelling than any reasons for remaking The Man Who Fell To Earth or The Quiet Earth or RoboCop? Oh wait, an R-rated remake of that one is already in the works. Guess the article was mistaken.

Science Programs Hit Hard By Proposed Budget

kindbud Re:Medicare bigger than DoD, Social Security close (395 comments)

The government doesn't have to default on the bonds - at any time the congress can just change the rules. There is no "contract" here, that you'll be paid back. There is only a law that can be replaced by another law at any time.

What are you going on about? Your wireless carrier, cable company, internet service, gaming service, mail service, news service, bank, credit card and so many others change terms unilaterally all the time. Private contracts like this seem useless as a means of guaranteeing future performance. Laws, by comparison, are practically eternal.

All future arrangements between people are contingent on those people complying with the arrangements at that future date. Laws are another step or two up the ladder of enforceability compared to private contracts.

Besides, you need laws to permit the enforcing of contracts.

Science Programs Hit Hard By Proposed Budget

kindbud Re:Is anybody really surprised? (395 comments)

Are you really against simplifying the taxes so that they are so simple and transparent that politicians could no longer play favorites with their soup du jour special interests?

How would a simpler tax code prevent corruption? Why not enforce the laws against official corruption that we already have or strengthen them? That makes more sense than changing the tax code.

Most politicians' special interests are the constituents in their districts. They got elected because they promised to play favorites in Congress with their own district's interests. Why would you not want Congresspersons to represent their constituents? Who would you prefer they represent instead?

Science Programs Hit Hard By Proposed Budget

kindbud Re:Is anybody really surprised? (395 comments)

Why do you imagine he hasn't educated himself? Because he disagrees with you? LOL

Do you believe it is a persuasive argument in favor of the Fair Tax to deride anyone who disagrees with your view of it as uneducated, with no further explanation?

Microsoft Kills AutoRun In Windows

kindbud Re:Option? (340 comments)

Hiding the filename extension is not a virus vector. Having the OS assume a file is just the type that the name says it is, is the vector whether the extension is hidden or not. Granting execute permissions based on its name rather than its permissions, is a virus vector. Assuming a jpg file is a image format and passing it unchecked to a thumbnail rendering subsystem is a vector, not hiding the jpg extension.

You can hide file extensions in Linux file managers. MacOS hides file extensions. Files with hidden extension are not going to be a vector for you or for Mac users on account of the hidden extension. They don't work that way.

First-of-its-Kind Hard X-ray Free-Electron Laser Images Intact Viruses

kindbud Re:"Laser", but not really (84 comments)

Because the word "laser" has taken on a broader meaning since it was coined, so that it is used to refer generically to any coherent electromagnetic wave generating device or phenomena. Laser is the Kleenex of physics.

Genghis Khan, History's Greenest Conqueror

kindbud Re:Smooth Move (279 comments)

These problems either go away or are greatly diminished with cheap energy, yet cheap energy seems to be one of the things the environmental movement vehemently opposes.

Damnit, you were doing great until this. Oil is the only cheap energy source we have. As you correctly pointed out, a byproduct of extracting energy from oil is the production of CO2, a substance with high stability due to low energy content. So it is difficult to get rid of without applying more energy to it to change its state to something more easily disposable, a task which is counterproductive. So of course, environmentalists are opposed to cheap energy, because there is only one source of it, and it is the source that causes the environmental problems.

Nuclear energy isn't cheap, and if it were, it wouldn't be clean. Cheap nuclear energy would likely be more immediately dangerous to human health and the environment than burning oil is. Also, whatever cheap energy source is discovered or invented in the future had better be very, very clean, because cheap energy will find lots and lots of new ways to be used, and used with abandon, because it's cheap.

The Prospects For Lunar Mining

kindbud Re:Energy requirements? (348 comments)

Luna is the Roman name for the moon goddess. The Greek name is Selene. Thus terms like selenography, selenothermal, selenotectonic are used to refer to processes and studies of the Moon.

Verizon To Offer iPhone Users Unlimited Data

kindbud Re:How long until we learn the secret limits? (327 comments)

How long do you think it will it be before people who have purchased the "unlimited" plan and taken it seriously will receive notices from Verizon saying that their account has been cancelled or disabled due to "excessive" use?

Probably never, that's my guess.


Data Usage
                October November December Average
Data Used(MB) 13674.39 7884.54 10850.83 10803.25
Data Over(MB) 0.00 0.00 0.00 0.00

Verizon To Offer iPhone Users Unlimited Data

kindbud Re:Yeah, right. (327 comments)

How many people will actually use an "unlimited" amount of data every month (i.e. - more than the 2GB offered for $5 less on AT&T, for example), if you can't tether?

I have a grandfathered Verizon mobile broadband account with no monthly data limit, and I routinely exceed 15 Gb/mo just listening to Pandora and other internet streaming music services. I listen to these services on my Droid Incredible now, too. I am sure I'd exceed the 2 Gb/mo in the first week of each billing period if that was my cap.

NASA Names Best & Worst Sci-Fi Movies of All Time

kindbud Re:It's even worse than that (610 comments)

The actual words are "Daylight Saving Time", much like you would say "Snake Whacking Day" or "Sheep shearing time", the word "Saving" is a verb here. Maybe the next poster will get it right.

Zathras good at doings, not understandings. When is Snake Whackings Day?

Android Text Messages Intermittently Going Astray

kindbud Re:It's open source (325 comments)

Why do so many readers of Slashdot have such an uninformed, anti-capitalist view of how the world works?

Well, to be fair they were educated in a world run by capitalist oligarchs who view public education as a cost center, not as a basic feature essential to the continued existence of an advanced society.

Navy Uses Railgun To Launch Fighter Jet

kindbud Re:A linear induction motor is not a railgun. (314 comments)

The USS Enterprise uses the same reactor design as the USS Long Beach CGN-9 (now decommissioned and sitting as a decapitated hulk in Bremerton, WA.). The Long Beach was the first nuclear powered surface vessel ever launched. The Navy only had two designs in the early 60's, one for subs and one for surface vessels. The Big E got 8 reactors because that's how many it took to drive it and also generate steam for the catapults. The Long Beach had two of them. Of course, she had no catapults.

Navy Uses Railgun To Launch Fighter Jet

kindbud Re:A linear induction motor is not a railgun. (314 comments)

They are producing steam for the generators that produce electricity for the engines.

Are you sure about that? Isn't the Gerald Ford one of the Nimitz class carriers? Those have steam turbines to turn the screws. ...after Wikipedia lookup...

Nope, it's the first of a new class. How about that. Last time I saw an electric motor turning a screw was at prototype training following nuclear power school.

Damn! They're going to launch it with systems installed that only use half the available generating capacity. They expect to be able to put lasers on it in the future and have the juice to fire them. Sci Fi is no longer Fi.

Undetectable Quantum Cryptography Hack Invented

kindbud kindbud writes  |  more than 3 years ago

kindbud (90044) writes "Vadim Makarov at the Norwegian University of Science and Technology in Trondheim and his colleagues have successfully defeated two commercial implementations of quantum cryptographic technology. "Our hack gave 100% knowledge of the key, with zero disturbance to the system," he says.

In standard quantum cryptographic techniques, the sender — called 'Alice' for convenience — generates a secret key by encoding classical bit values of 0 and 1 using two different quantum states of photons, or particles of light. The receiver, 'Bob', reads off these bit values using a detector that measures the quantum state of incoming photons. In theory, an eavesdropper, 'Eve', will disturb the properties of these photons before they reach Bob, so that if Alice and Bob compare parts of their key, they will notice a mismatch. In Makarov and colleagues' hack, Eve gets round this constraint by 'blinding' Bob's detector — shining a continuous, 1-milliwatt laser at it. While Bob's detector is thus disabled, Eve can then intercept Alice's signal. ... The cunning part is that while blinded, Bob's detector cannot function as a 'quantum detector' that distinguishes between different quantum states of incoming light. However, it does still work as a 'classical detector' — recording a bit value of 1 if it is hit by an additional bright light pulse, regardless of the quantum properties of that pulse. That means that every time Eve intercepts a bit value of 1 from Alice, she can send a bright pulse to Bob, so that he also receives the correct signal, and is entirely unaware that his detector has been sabotaged. ... "We have exploited a purely technological loophole that turns a quantum cryptographic system into a classical system, without anyone noticing," says Makarov.
