From what you wrote I understand that you are blind. I agree that someone should have written a better caption for the picture.
That is either commendably sensitive or an excellent put-down. Well played either way. I swear I didn't notice the damage to the keyboard, and somehow pictured them shooting the laptop with the display opened.
The purpose of the shots was most likely *not* the destruction of data on the hard drive, but the disablement of a potential explosive device
OK, but (as the girl herself points out): If the shots hit only the screen, how effective would that have been? Are most explosives disabled when you shoot a thing next to them that's connected via a hinge and a cable? And if so, isn't a much better solution for Israel to build a Kevlar laptop dock, routinely plug EVERY laptop into the dock, and shoot at the dock? Or maybe they could just stick a pin into a little doll that looks like your laptop.
they produce an equal but opposite noise (waveform)
Yep. A naive noise-cancelling earphone design would be a mic, mic preamp, phase inverter and a summing amp to mix it with the input signal. Nowadays I'm sure they have some DSP as well, though latency would make it difficult to do anything fancy. IIRC, the hard part of noise cancelling is getting the mic as close to the ear driver as possible so it hears the noise at the same time as your ear; otherwise the distance puts some sounds out of phase and you end up boosting instead of cancelling.
so in fact you're being subjected to double the noise level, but can't hear any of it?
Not sure; that's where I remember I'm a software guy. But that's certainly what it feels like, and maybe someone who actually knows physics can enlighten us here.
It's common to see musicians playing with plugs stuck in their ears so they don't drive themselves stone deaf
Keep in mind that they're standing right next to the drummer. Anyone within spitting range of a drum set ought to be wearing plugs. Also, electric guitarists often need to overdrive their amps AND feed back the amp signal into the guitar pickup; that requires standing in front of a loud amp. Also too, many musicians wear in-ear monitors these days, so those "plugs" may well be the monitor mix.
Gah, I hope not. Noise-cancelling headphones make me feel like I'm in some pressure chamber. I've seen it mentioned by others, but I've never found out if it's because they really do increase absolute pressure when they play the cancelling waveform, or if it's just a psychoacoustic thing from comb-filtering. Either way, it hurts, and things that hurt your ears tend to harm your ears.
"We're a monopoly, you say? Sir, the word 'monopoly' is not even in my dictionary."...in fact, everything from 'marzipan' to 'morass' seems to be missing.
Tandems may still have other advantages, though; back in the day, we built a database on Himalayas/NSK because, availability aside, it outperformed Sybase, Oracle, and other solutions. (They implemented SQL down at the drive controller level; it was ridiculously efficient.) No idea if that's still the case.
But Tandem required you to build their availability hooks into your app; it wasn't transparent. OTOH, Stratus's approach is;a Stratus server is like having RAID-1 for every component of your server. I gotta think this will cut into their business.
One botnet will get hit. Others will get the idea and hit other botnets.
And then somebody approaches the bored hacker and says "You're just doing this for fun... wouldn't you like to make a boatload of money for doing exactly the same thing?"
Isn't that exactly how this got started? People wrote viruses for lulz. Then someone offered them cash.
They express facts that don't change depending on who is asking for them.
See, you're making Paul's point better than he does! Even in his comment above, he just says that "All DNS responses issued by our DNS servers were absolutely factual in the policy they expressed." - which is in equal parts true, predictable, tautological and irrelevant to his own point.
Looks like this article is more about, "what DNS is becoming but I don't like."
What DNS is not is a mapping service or a mechanism for delivering policy-based information. DNS was designed to express facts, not policies.
Erm.. didn't Paul create MAPS to explicitly provide - and later monetize - the RBL? Wasn't the RBL a "directory service"? Didn't it map IPs to policy-based information?
I agree with the point he's trying to make; I hate NXDOMAIN hijacks too. I don't get the rant about CDNs, though; seems to me that as long as they're controlled by the domain owner, not a man-in-the-middle, there's no particular distinction between a CDN and plain old round-robin load-balancing.
Yep. It's just a rant on "ways to use DNS that Paul Vixie doesn't like".
You left out a few parts of the overkill solution:
5. Excellent O'Reilly book on Asterisk 6. RSS feed for NerdVittles / PBX-in-a-Flash 7. Copy of VMWare Fusion because hey, why bog down the Linux server when you have a fast desktop? 8. Subscription to TWO different SIP providers because you want to compare call quality 9. iPhone to use until you get around to reading that Asterisk book...
hypothetically, I mean. I'd imagine. Pure conjecture, you understand.
In general, Google wants to solve every problem with an algorithm - and if it can't be solved with an algorithm, then by definition, it can't be a problem.
Either way, if I'm trying to read a 10cm-wide display that appears to be a meter in front of me, I'm going to lean forward to read it. Of course, that's futile with a retinal display... I predict a lot of hunched-over early adopters!
Me too - in fact, we belonged to two different library systems. But books aren't timely; in those days, lead time was 5-6 months for magazines, probably longer for books. And I didn't do RPGs.
Environmentalists may have more protein, but kittens are already productized. Wellness (a gourmet pet food brand) sells the usual chicken formula, beef formula, etc. But, although it's not well-publicized, they also sell kitten formula.
I'm always struck by my pre-Internet memories, because I have no recollection of how I learned timely, geek-related facts. I was a huge Trek fan in high school, and I knew all about conventions and movie plans and whatnot. I'm sure I got some of it from BBS's, and I must have subscribed to some 'zines, but how did I ever find those without - not just without the Internet, but without ubiquitous search?

I'll just shut up now.

Similarly... If the output level is limited by law, doesn't that just create a market for lower-impedance headphones?
A Slashdot comment thread, I should think.
"We're a monopoly, you say? Sir, the word 'monopoly' is not even in my dictionary." ...in fact, everything from 'marzipan' to 'morass' seems to be missing.
And from you, we should take advice?
Well, of course not - otherwise something something something lawyers.
Wouldn't we want the TSA to infringe every possible civil liberty, so that we could sue to overturn the rules?
Wait - it gets better. Wouldn't we want to LOSE all the lawsuits, so we could win on appeal and set binding precedent?
Short of that, I think "TSA changes policy" is a pretty good outcome.
I was just thinking that...

This is awesome. I wish you'd de-anonymize so I could quote you.

You've been reading the Lexicon of Intentionally Ambiguous Recommendations, haven't you?
True, but why worry about small-time scams like casino gambling? There are larger issues at stake; this is a matter of principle.
