How does that fix anything? The magstrip is a fixed value, and thus easily duplicated. The chip performs a computation resulting in a unique value that's only usable once.
AT&T (Citibank) mastercard... click a few boxes on a web page, and "it goes away". (Of course, they lock my card every time I try to order anything from Newegg. Even two back-to-back transactions will get the card locked twice.)
Why don't they just go back to having to have the physical card...
Do you have any idea just how stupid-simple it is to duplicate that plastic card?!? (including the magstrip) The only thing that makes it complicated is the "chip" and a security hologram -- if it has either of them. And since you swipe your own card 99% of the time, there's no one to actually check the hologram.
(I recall a major ATM scam where the guys were manufacturing cards using a calling card as the base plus a stip of VHS video tape. They were caught with boxes of those things -- which would amount to thousands.)
Cash requires one to actually have the money in the first place. Credit Cards operate on the notion of CREDIT, thus, allowing people to spend money they don't have. (in far too many cases, money they'll never have)
The simple fact that two of the designers patented solutions to address the backdoor, and in so doing, very clearly described the problem, is about as smoking gun as it gets without an HD bullet-time video of the gun actually being fired.
While we have no proof the NSA knows any secret constant, their involvement, the push to use it ("bribing" RSA), and a standard requiring their chosen constants, is very damning evidence, indeed.
OpenSource has nothing to do with it. Here we have (allegedly) a set of carefully crafted constants used in a crypto context. Without knowing why those specific numbers where chosen, or that they are, in fact, not "weak", everything using them, open and closed, is suspect.
(I would tend to agree the NSA -- having had their hands all over the thing -- do know the secret relationship between P and Q.)
a) "school" now includes "internet" (unlike when I was a child and we learned from books) b) devices do this shit entirely on their own with zero user interaction.
Actually, the router does transmit... to the inside interface. With a bit of buffering, or dropping traffic -- but as it's already crossed the link, you don't want to have to receive it again -- it is entirely possible to rate limit traffic in both directions. Knowing *what* to rate limit is the issue. If he knew what sites were "update" sites, he'd just block them entirely.
It almost always takes more than 20sec. And it requires a real (circuit switched) phone line. For small retailers, this works. For a big chain store, with dozen of lanes, individually processing each CC transaction would be complete murder; no one is going to wait even 30s for a CC authorization these days. How long did your last CC purchase take? Under 5s? Now imagine standing there for 45s.
I think that's a ringing endorsement for not using Microsoft Exchange, plus however many 3rd party add-ons and "business process integration" crap corporations always bolt-on to it. Exchange on it's own is fairly reliable -- as long as you aren't constantly poking at it. (even more so if you don't let the internet talk to it.) But there are, indeed, significantly more stable email platforms than Exchange.
Actually, they do care. They just do it in uber-secret. (however, with a ban on testing, it's all theoretical. even if they do build it.)
The real issue is, indeed, one of cost. But that's because of the extreme amount of paperwork and permiting required to even buy "lab samples" today. And for good reason; nuclear material is seriously dangerous. You don't have to build something large enough to level a city; in fact, that's a small concern (you'll never get that much material.) The risk of contamination and/or poisoning is very real.
Really! If they don't want people using it after hours, turn it the f*** off. Turn the power down so you cannot see it a mile away. Almost every AP I've seen has radio control settings. And those that don't can be plugged into a X10 timer.
Actually, it's the other way around. The company that originates the call pays the company terminating the call. (reciprocal compensation, 'tho it's a very muddy river.) Inter-VoIP provider traffic doesn't necessarily have to ever touch the PSTN.
Plugging in a fax machine will almost always backfire... you'll now be getting un-ending fax spam; they'll *LOVE* that as it costs them nothing at all. (no person has to be "standing by" to take your CC information)
We used to get a bit of lame phishing fax-spam, so I set the machine (big office printer) to send them to a computer instead. It has led to a few WTF's until people remember that email I sent back in 2008.:-) Nobody faxes anymore; you scan it and email it.
Look closely at the voice coil setup. Notice those two magnets are very close together? The magnetic field lines are 99.9999% perpendicular to the surfaces; VERY little of the field extends beyond the assembly. (and effectively none extends all the way to the platter(s).)
Anonymity and privacy have grown out of the various "bitcoin exchanges" (aka "banks".) The only public record of a transfer is into the exchange, from there the bitcoin never appears to change hands until (and unless) it leaves that exchange. (and if it's moved to another exchange directly, no actual end-user knowledge is published.) But like everything on the internet, it's very hard to maintain 100% anonymity.
[Yes, doing so is very dangerous as those bitcoins cease to be yours then. But this is what's necessary to make fractional BC transactions.]

Or even "oil pan"...

Become a victim of identity theft and then tell us how much you didn't lose and how little effort it was to get it all back / clear your good name.

I win! Original Hayes Smartmodem 300. (bulletproof aluminum case and all) [still functional, as far as I know]

They aren't going to admit shit, for purely financial reasons. (they'd be sued out of the solar system for this.)

Reading the post, I immediately said, "not the best you can buy, just the best you're willing to pay for."

... that only works from 11am to noon on the third thursday of each month. (redirects to bing, which is also broken, all other times.)

Maybe, but this stuff is a gamma source, so it would be detectable at a fair distance. (vs. alpha and beta that wouldn't make it out of the truck.)

It's a search if he touches anything. Just looking at what any passer-by can see, is not.

Silver, gold, platinum... that's gonna take one hell of a match! :-)
(granted most of what's in circulation is silver, copper, nickel, and lead)
