Have you tried shorting the two power pins of the power plug together? Just tap'em simultaneously with a screwdriver. Maybe a capacitor inside the power supply is charged up and somehow it's blocking the flow on a different phase. If so, it's crappy engineering.
Obviously, I mean that you should do this with the plug UNPLUGGED.
The shockwave propagates through a medium at the same velocity as more conventional compression waves (sound)
No.. By definition shock waves travel faster than the speed of sound in the medium. Eventually enough of the energy of the shock dissipates as heat and the wave drops to sonic speeds, at which point it is no longer considered a shock wave.
Could some kind of supersonic resonance be set up in a piezoelectric crystal? Maybe, although I can't see how it would be done, but in any case I would not describe it as being sonic.
Actually, it's what you'd expect. Animals would naturally evolve to move in an efficient manner. It would give them an evolutionary advantage. What the bleep did these guys expect?
This sort of statement is destructive. Should we abandon all scientific experiments whenever we feel we already know what the results will be? Sometimes the obvious assumptions turn out to be very, very wrong.
Aristotle once thought it was obvious that all objects eventually return to the "natural state" of being at rest. Looking around us at a world with gravity and friction, this sort of thinking is not hard to understand. Unfortunately, Aristotle was revered by thinkers for nearly two thousand years before Newton and others came along and actually bothered to do some experiments. One man's opinion impeded scientific progress for two millenia because nobody dared to question his authority.
How about sending the e-mail along with the list, so you don't get ANYTHING back, but a "mail sent" message? In other words, why not make OFFICIAL SMTP servers which filter the e-mails?
All right, so now we'll have official, government-sponsored, porn-spamming SMTP servers? Sounds great.
My spouse has watched with amusement over the years as I have attempted my first task of the morning - making my espresso. It's a 50% shot if I can pull this off the first time, without forgetting to add water, add beans, turn on pot, plug pot in, get coffee cup, avoid cracking head on cupboard doors, etc. By the time I have espresso in cup in hand and I'm right-side up, I'm OK from there.
Your error is that you only practice in the impaired state. You can't develop a good engram (roughly, "muscle memory") for the espresso-brewing task if you always practice it while sleep-stoned. What you should be doing is practicing making espresso at 3 in the afternoon, when your brain is actually functional. Brew ten batches of espresso, back to back. Soon the process will be committed to your unconscious memory and you'll be able to carry it out even in the impaired state.
how can you write about a study that did research on 16 people.
this number of participants is nowhere near scientific. it must be a joke.
Misunderstandings about the significance of scientific results are common. Consider the following test. A sample of 16 people is selected. 8 of these people receive a blow to the toes with an 8 pound sledgehammer. All 8 of these people scream loudly. The other 8 people do not receive a blow to the toes. These people do not scream.
From this experiment, the conclusion can be drawn that if you crush a person's toes with a sledgehammer, that person will scream. Now, are you going to dispute this conclusion because the sample size was only 16 people?
Whether or not a result is significant depends on sample size and many other factors as well. Go Google the term "statistical significance." You'll find that it's an incredibly complex (and mostly boring) topic. Results should always be looked at critically, but you cannot unilaterally say that there is something wrong with a sample size of 16 without knowing all the parameters of the experiment.
Real criminals ain't that stupid. Do you know how real pedo's get their kids? They kidnap one, use them and kill them and dump them and never ever leave details like paying for the kids email adress.
No, "real" pedophiles (whatever the fuck that is supposed to mean) entice children on chat boards and set up agreed-upon meeting times. Typically the kid is unharmed, at least physically. And typically, nobody ever finds out about it. Kidnapping and murder? You've been watching too much CSI.
Although considering there are about 5 replies like you I may be wrong. Perhaps IT geeks are not so smart after all.
So, my skills at coming up with ways to exploit children are lacking? Wow, I feel so ashamed.
I'm like that as well. That's why God invented coffee.
It's not the OP's fault how the post gets moderated, but this isn't really insightful... Ever drank coffee while drunk? You don't get sober, you just become a hyperactive drunk. I would imagine that a caffeine hit immediately upon waking would probably just produce a groggy, bleary, hyperactive pissed off tired person.
Besides, I don't drink coffee to wake up -- I can stay awake all day just fine without it. I drink coffee because I'm addicted. Oh well.
The other guy has to be able wake up and roll into a firing position the instant anything Really Bad starts happening. It took me years to break that habit.
So like, you'll be sleeping next to your wife, and she makes a noise or something, and you instantly wake up and roll into a "firing position?" Sounds like a good deal for your wife!
What we need is a loud alarm-clock with no or very limited snooze that cannot be turned off (its alarm would stop after say 5 minutes). The time and alarm settings could only be altered in a fixed window (say between midday and midnight), and the thing would be indestructible. What do you think?
What I think is that it's amazing that some people have so little control over themselves that they require a device like that in order to get out of bed in the morning. Seriously, if you'd rather smash an alarm clock than simply get out of bed, there is something wrong somewhere and the problem does not lie with the alarm clock.
There about a dozen posts so far pointing out how this gives spammers/pedos a list of kid email adresses. RTFA you stupid morons. Spammmers that want to comply have got to send their list to the state and the state does the checking. The spammer never gets the registry.
I see, so you send away a list, and get back a list with all the kid's addresses removed? Let me tell you about a tool called 'diff'...
Really now, why is everyone so upset about this? Freedom of speech does not guarantee freedom from the consequences of such speech. Duh.
Actually that's exactly what it means. Your argument is bogus. What if the consequence of insulting the President is five years in prison? Are you saying I'm still "free" to insult him and I just have to learn to live with the consequences?
but as we start to experince this new broadband boom, we'll see dozens of services that were just waiting to come out, Video On Demand rentals of HD Content, Full Stereo Phones, Video Phones (Instead of crappy webcam chats), and more I'm sure someone with more time will think of.
But that shit ain't interesting. Can you come up with some cool new use for large bandwidth that does not simply boil down to "downloading reams and reams of shit, really fast?" It's like putting bigger and bigger blocks in your truck. Other than driving up steeper and steeper hills, what the hell does it get you? At some point you want to start thinking about other things.
Your use of the term "speed" is confusing. Why not just use the correct term which is "latency?" Speed encompasses both concepts.
However thier advances MUST go hand and hand
Laughable. You can only push latencies so low (the whole speed of light thing, remember?) but you can make bandwidth arbitrarily large. So they cannot go "hand in hand" forever.
and the the continuation of the current AJAX and comprehensive webapplications initiatives (IE GOOGLE and SUN's OFFICE suite)
Like all other "world shaking" developments in the computing world, AJAX will turn out to be a pile of garbage. It's a step into the future, like all developments. And all those developments are ultimately cast down and replaced by something less stupid. Don't blow your load yet.
no? when broadband means a hell of a lot of difference when downloading two to five 700 meg ISOs of the latest release of your favorite Linux Distro? try that on a 56k dialup...
But that's not the context of the discussion. Yes, obviously the jump from 56k to megabits is a serious jump. But is a jump from 2 megabits to 5 megabits worthwhile? If I can download an ISO in 20 minutes, do I really care if I can get it in 8?
There are far more applications today that can utilize the faster broadband, both upstream and downstream. For a few examples, consider P2P, VoIP, video streaming, etc.
With P2P, you have a point. But VoIP? The bandwidth requirements are piddling. We're talking mere kilobits. You can run it over a (high speed) modem connection. And even video doesn't tax a 5 megabit broadband link, unless it's extremely high quality.
Give many people more bandwidth; they'll find a use for it. Feel free to replace "bandwidth" with just about anything and it likely would be true as well.
The ONLY use for such bandwidth is leeching off P2P networks. More bandwidth == More ISOs. I challenge you to find any other consumer-level use for enormous bandwidth. Full-on virtual reality maybe, but that's so '80s...
That does, of course, depend on finding a way of cooling the conductor to near absolute zero along it's entire length, using less energy than would be lost during transmission on a normal cable. In other words, it's a pretty ridiculous suggestion
Well, you're replying to a moron. His quote, "Thus preserving the most amount of electrical charge during passage" should have tipped you off to the fact that the submitter has no fucking clue how either electricity or superconductivity work.
Why waste energy criticizing the submitter... The articles themselves are full of enough bullshit already.
While that is true, this could also be a simple null pointer dereference, caused by incomplete error handling in the code somewhere. Those sorts of failures are typically not exploitable.
Just because A implies B, does not necessarily mean that B implies A. All overflows are crashable bugs, but not all crashable bugs are overflowable.
It's easy enough to find out -- load the core file into gdb and look at the instruction that crashed. If it's a null reference, chances are this bug is no big deal.
I know I'm not. Suppose I delete a paragraph with the intent to rewrite it, muck around for a while and then decide I preferred it the way it was? If everything is saved automatically, that original paragraph is lost.
Sure, I could Undo back to the previous state, but I've seen so many programs with broken or unreliable Undo that I simply could never trust that. Or what if the editor crashed before I could Undo?
The only way you can do away with user-directed saving is with some sort of automatic versioning system. But then, how often do you version? Whenever a single byte of information changes? Less often? How do you determine it?
What a pain in the ass. I'll keep my Save function, thanks.
Or people don't grasp that a dog is a slave to man
A dog's behavior might seem fawning and servile to us, but is it really? He has, after all, managed to convince us to feed him. Maybe we're the ones who have been duped.
When you think about it, dogs act a lot like parasites. Almost everywhere except the cities of the First World, feral dogs are tolerated because they clean up garbage and have sufficient "cuteness" that people won't kill them or banish them. Perhaps it's we who have been 0wnz0red by dogs, not the other way around.
The idea of owning a dog as a personal pet is relatively new. In ancient times, who had the resources to give a portion of their own food to maintain a pet? Only the rich could do that, and owning a dog was a sign of status.
Cats have also been historically used as rat control. The cat may enjoy this task immensely, but it is in fact serving a human purpose.

I assume because Hair Of The Dog is a brewery, and they only make beer. Is there some other HotD I am unfamiliar with?
