I stand corrected on the Mercury bit. The perihelion shift is explained by the non-Euclidean spacial geometry induced by the mass of the sun, on further reading. The effect I was thinking of on Mercury wouldn't make much sense, come to think of it. Oops.
Still looking forward to the laser beams that can redirect planets just by passing by them. (Lens this!) Guess that'll be right around the time that we start using laser beams as propulsion:)
For instance, photons cannot attract each other gravitationally (whereas matter does), and a photon won't attract matter gravitationally.
Photons do attract matter gravitationally. It causes the perihelion shift of Mercury, which is one of the tests that lead to wide acceptance of general relativity.
Under general relativity, "spacetime curvature" replaces the "force of gravity" as a paradigm. Photons make their own little divots in spacetime in accordance with the mass equivalence of E=mc^2.
Good point. OOB with callback is a good security measure, but certainly limits flexibility. It's a balance, I suppose.
I wonder, though - is "callback" ever used in in-band management software? That is, you connect to a service, it drops the connection and then connect to a predefined address. Possibly vulnerable to MITM. SSL with two-way certificate authentication plus password would be adequate, but would likely be impractical with the embedded devices we're considering. Even when it is practical, it can't replace OOB management, but it could make in-band management as secure as OOB.
Because it makes you lazy and forgetful, and what's worse for our corporate overlords, makes you think
Cannabis makes the most ridiculous thoughts seem profound and important. The world becomes more interesting, more beautiful, more menacing. It can be a pleasant experience, but it's no road to cognition.
Cannabis doesn't make you think. It makes you think you think.
Good point. As you pointed out in your other post, I'm not familiar as I could be with Sony's products. Though one could argue (with difficulty) about the minidisc players, the CD ripping software for MP3 players really stretches credibility, like a VCR that's intended only for recording home videos.
It's silly that Sony considers copying music you've purchased to your iPod. I was commenting on the submitter's silly implication that because Sony's devices allow this, they are responsible for same.
The question can be easily turned around - is it okay to send unsolicited emails to the US, UK, and other similar countries, encouraging users to engage in subversive acts for which they could be fined or imprisoned, because you disagree with a policy of their government? What would you think of a foreigner or foreign agent who did that? What impact might it have? Think of all the people who say "I block all email from China because I receive spam from there."
A closely related question is whether politically- or idealogically-motivated spam is okay, if one assumes that commercially-motivated spam is not.
My feeling is that unsolicited bulk email is never okay - it raises the noise floor in an already noisy medium.
A hybrid can't make an engine more efficient. It just makes it more efficient over certain parts of the power band. Unless they redefine hybrid to mean starter-alternator with minimal power assist there are going to be a lot of cars that don't see any gain. Incidentally I do think every car will (and should) have a starter-alternator in that timescale.
A hybrid drivetrain allows a vehicle to be built with a smaller engine, consuming less fuel. The engine only needs to be powerful enough to maintain cruising speed, where a regular engine would need to provide enough torque to accelerate from a stop as well.
I see what you're saying - a hybrid drivetrain should have no impact on steady state efficiency (highway cruising). However, a smaller engine with the throttle open will be more efficient than a larger engine running at half throttle, so a hybrid may come out ahead even in this context.
According to the article, the yellow light "silences" neurons that have been engineered to include the halorhodopsin gene found in certain bacteria. The light doesn't have the same effect on the neurons that you'd typically find in your skull.
I'm not sure how this would be used clinically to treat epilepsy. Perhaps by introducing the genes into cells in the affected area using a retrovirus?
Who wants to spend the thousands of dollars or tens of thousands of dollars to take someone to court who has a big, fat, malicious mouth but no money with which to compensate even when you win?
People with big, fat, malicious mouths but no money rarely have enough influence to cause enough actual damage to warrant a slander suit.
You're probably right - even if you were innocent, it would probably be easier to fork over the cash. Though, given the pervasiveness of copyright-violating content sharing, you'd be hard pressed to find a suit launched against someone truly innocent.
If you have already filed your income tax return electronically, the CRA will be able to determine whether the filing of your return was affected by this problem.
You're comparing maximum sentence to an actual sentence. The accused probably won't get anywhere near 10 years in jail or $500,000 fine.
Also, though it's light, 10 years probation is not scot free. The infotainment blurb linked doesn't cover the circumstances around the accident nor the mitigating factors that led to the sentence.
Over the last year or so, I've considered writing an automated wireless network intrusion tool. It would:
capture encrypted packets and attempt to crack wep/wpa keys
join wireless networks, enumerate targets
retrieve files of interest from shares or recover them from packet dumps
launch code attacks, like this tool does
You'd run it on a laptop that you'd carry in your backpack or in your car, on your way to/from work or just cruising around on a Sunday afternoon.
As such, it would be called the Transient Wireless Intrusion Tool, or TWIT. I just get a charge out of network security people writing about twits wandering around near the network.
Whatever it was, though, after '95 the floppy disks which I've bought have an average lifespan of about three months before random errors begin appearing on the media.
Floppy drives are rarely used and have outside air continuously drawn through them while the computer is on, collecting a significant amount of dust. When they're called into service again, the vibration of operation drops the dust and debris into the disk, and the full-contact readwrite head ensures that the dust is ground in nicely.
Back in the days when floppy drives were used daily, there wasn't opportunity for this amount of dust to build up.
One strategy to improve floppy disk reliability these days is to pop in a "sacrificial disk" and do a few operations on it before putting in the actual disk you want to read/write. Another alternative is to use a positive pressure case with an air filter on the intake.
There are special computers that have pages, like from a book. Those special computers have something that lets you go to them, like each telephone has a unique number, but it more resembles words.
That's how far I got into your explanation before my eyes glazed over.
"Tubes" was a perfectly good metaphor for the layman - you put data in one end, some magic happens, and it goes to the right place. This metaphor also implies the limited capacity of the connection, unlike your description. The senator was referring to this limited capacity, not giving a tutorial on how the internet works.
Tailgating 18-wheelers is not safe. It's safer, though, than tailgating a Civic that can stop on a dime, crumples like a can on impact, and pushes like a sled into oncoming traffic.
Yeah, people get killed because their car wedges itself under the trailer and cleaves the top off the passenger compartment. I think most trucks are supposed to have guards that are low enough to prevent this, specifically to prevent this from happening, but I don't think all do because I still hear about it happening from time to time.
This sounds more like a high-speed impact than a tailgating accident. A tailgater would have a fairly low speed relative to the back of the truck.. unless they really weren't paying attention and didn't even hit the brakes, in which case all bets are off.
Some trucks are using something other than airbrakes now? I'm interested to see more about this. Off to the wiki!
In fact, I've seen cars tailgate 18-wheeler trucks. Some people just never learned what a safety distance is.
Tailgating an 18-wheeler is one of the safer forms of tailgating. The truck can't stop faster than your car. Even if the stop should catch you off guard and you impact, it won't likely throw the truck off the road (due to mass), or your car (due to being pinned under the trailer). Much better than, say, a GMC Suburban tailgating a Chevy Sprint.
The worst thing about tailgating, as I see it, is that it requires much more attention, both from the tailgater and the driver in front. That means much less reserve capacity for important things like obstacle avoidance - obstacles like potholes, deer, pedestrians..

Exactly. The same security concerns that apply to network management interfaces apply to OOB management interfaces.
Good point. OOB with callback is a good security measure, but certainly limits flexibility. It's a balance, I suppose.

Wardialers are to OOB management as portscanners are to internet-connected management.

Out of curiosity, what software do they use?

Hammers can be used to break into cars. I guess somebody should tell Home Depot that all their hammers allow this to occur!

Doh. I browsed down to 1, thinking someone would have modded it up. Guess not.
Sounds like somebody has a case of the Mondays!

In other words, feel free to write off whatever the hell you want this year, because you officially have plausible deniability.
Not quite, according to their update:

Sorry for the confusion.
