Better example: in an age where Raspberry Pi's are being celebrated by mass media as the next big thing in education, it seems unlikely that this envisioned total lockdown will happen any time soon. After all, no politician wants the other guy to be able to point at him and say "my opponent opposes giving children a proper STEM education!" So, maybe the big lockout will happen if Microsoft can get its hooks into the embedded/maker world via its godawful Windows 10 IOT core, but not before.
Very messy indeed. All the heavy elements we see around us, it's mind-boggling to think of the energy that must have been required to blast them out from the core of their collapsing star.
Here's another way to think about it: Don't think of the black hole event horizon and singularity as different things. That is probably what's confusing matters. Instead, think of the black hole as a single object, with its event horizon as its "surface". Anything that touches the "surface" disappears and adds its mass/energy to the black hole. However, because of the requirement that the virtual particle pair has a sum energy of 0, and the fact that the escaping particle has a net positive energy, the particle that falls into the black hole must have negative energy, and adding that negative value to the black hole is what causes the black hole to lose energy.
Alternatively, the particle that falls in could be thought of as leeching energy from the black hole and transferring it to the escaping particle, in a way that would look to an outside observer as though a particle inside the black hole suddenly appeared outside it. That's what the article probably means by particles "teleporting" out.
Not quite. The virtual pair has a net energy of 0, and therefore isn't really "extracting" anything from the vacuum. If the pair weren't straddling a black hole, they'd recombine and disappear and nothing would happen. However, when one member of the pair is sucked into a black hole while the other particle escapes, the escaping particle must have a greater-than-zero amount of energy. Because of that, and the requirement that the two particles balance each other out, the black hole has necessarily absorbed a negative-energy (not negatively-charged, mind you, actually negative energy) particle, causing the black hole to shrink ever so slightly. Basically, while the particles originally came from vacuum, the energy was taken from the black hole.
Also, to an external observer this process looks exactly the same as if the black hole itself was slowly emitting particles and shrinking away. And if the black hole is emitting particles, we can use that to determine something about its internal state.
Funny story. My brother and I tried to set up an ad-hoc wifi network to play some multiplayer games. I run Linux, and was able to create the ad-hoc network easily (just by "clicking on things", of course) and the game ran flawlessly in WINE. My brother could run the game, but guess what? Windows 8 takes a big step back and shits all over the concept of ease of use, because it doesn't let you connect to or create ad-hoc networks without opening a command prompt and invoking a set of arcane powershell commands.
So, there's my little anecdote. WIndows has a very thin superficial layer of usability, but when you want to do anything marginally difficult (even things that were easy in a previous version), Windows makes it next to impossible. Meanwhile, it's easy for any simpleton user to do the same thing in Linux.
Yeah, how dare we be upset that a product we paid good money for would suddenly stop working because of the whims of some corporate executive? We should just accept the loss of our hard-earned cash and buy more stuff from the large greedy corporation that screwed us over.
Or, you know, we could be justifiably upset that a product we paid for was disabled after the fact. Sounds like you have more money than sense if your response is "throw it out and buy something else".
Nothing might be technically illegal about posting names of non-paying customers, assuming the list of names is correct. But cable companies are notoriously bad at keeping accounts in order themselves, and the moment they try the name-and-shame on someone who actually is a paying customer, they'll be on the hook for libel.
He should be tried and convicted for several hundred counts of manslaughter, at the very least, but I bet you could convincingly argue for a couple counts of "aiding a terrorist organization" as well, and then jump from there to "treason by aiding the enemy during a time of war".
Sadly, nearly all bugs fall into the category of "obscure, but simple to fix". Also, in my own experience, the bugs which have taken the longest to track down the root cause have also been the bugs whose fixes only required a couple keystrokes.
Mercury gets plenty of heat from the sun and has an absolutely huge metal core.
Not sure about Venus, though. Maybe it has a smaller core than you'd expect for a planet its size? It's difficult to tell, since its atmosphere has a nasty habit of melting all our probes.
I doubt Linux would be banned entirely (it's in use by too many big businesses), but I could see only certain "approved" distros being allowed. I'm sure Red Hat would jump at the chance to be the sole government-approved official Linux provider, and I doubt they'd even think twice about including a few "special" government-provided packages in their base installation.
... a huge win for the music community and legitimate music services. ShareBeast operated with flagrant disregard for the rights of artists and labels while undermining the legal marketplace."
Look, I agree that ShareBeast (first I've heard of it, though, so how big was it exactly?) was screwing over the artists. But the RIAA has just as much contempt for the artists as anyone - even more than pirates, since the pirates at least appreciate their works - and there's no end to the stories of hardworking musicians who've been bankrupted by RIAA execs with lots of big promises and lots of fine print in the contracts.
Just sayin'... I expect a similar statement to be made about the RIAA and its members when they eventually crash and burn.
Seriously, who uses telnet instead of ssh in this day and age? I think we're at the point where including telnet - even optionally - in any Internet-facing device should be classified as a malicious act.
I'll just quote gstoddart from earlier in the comments:
The other way is if this stuff becomes easy enough to become a cheap device or an app for your smart phone... then the bad guy presses a button which says "all cars which are ready to be hacked please honk your horn".
Just like script kiddies and other scams, if it's lucrative enough, and easy enough, it'll happen. You don't have to be a high value target. If someone knows they can pop the locks on every Escalade in the parking lot, they're going to do it. And someone might just say "oh, fuck it, let's make all the Corvettes disable their brakes because it will be funny".
If the last decade or so has taught us anything, it's that if it can be hacked, it will be... and if it's worth doing, it will be done.
So you may be unimportant, and nobody is likely to *personally* hack your car... but nothing would prevent a motivated hacker from compiling several exploits for the most commonly driven cars into a single program that any script kiddie can use. And it really won't matter to you whether your car was singled out by a malicious entity, or merely one of thousands, if the brakes and steering are disabled at 60mph.
That's nice to hear and all, but it doesn't fit the reality that I and the GP have experienced. A vanilla Windows install on most laptops is going to be a barely-functional pile of crap until you're able to download the dozens of special drivers required for that laptop's dodgy hardware. Just pray that your network card works out of the box.
Unrelated to privacy, but why the hell are they removing USB floppy support from Windows 10, only to force you to download a separate driver? What, was the Windows 10 DVD image too big by like 10kB?
Let's try not to jump straight to blaming the victim. It's also possible it's due to the location he's in, or maybe he's right and he's getting passed over in favor of a fresh batch of exploitable college kids or H1Bs.
Since this exploit uses an interaction between javascript and Firefox's built-in PDF viewer, it sounds like this doesn't affect people running NoScript. But what about people who don't use the built-in PDF viewer? e.g., if clicking on a PDF file opens the usual "download/open file" dialog, will the exploit still work?
How were these clearly bogus laws voted in, in the first place? It seems pretty obvious that documenting health/safety violations would be protected from legal retaliation, much like how truth is an absolute defense against libel charges. Otherwise, there's no point to even having health or safety codes, if corporations can just say "yeah yeah, we're up to code, but no peeking!"
In my one and only encounter with Windows 8, I discovered that it refuses to acknowledge that ad-hoc wireless networks exist. It won't list them, and you can't create them, without going into the godawful Windows command line! Meanwhile, my Ubuntu laptop can create one in three clicks, and it's only a little more annoying to do the same in Windows 7.
So my question to you Win10ers out there... have they corrected this glaring flaw*?
Dropping down into the terminal to fix a network connection is something I haven't had to do in Linux for years, and Linux's terminal emulators are at least pretty good at what they do. Having to use the Windows command prompt to do something is absolutely agonizing, and the knowledge that it was completely unnecessary in previous versions of Windows is infuriating.
*which, by the way, I'm sure is rooted in the idea of "all our users are drooling idiots and all ad-hoc wireless networks are malicious"

I assume the receiver would attempt to decrypt every package and simply throw out any failures.
Zero, most likely. Because the government be shouting "the system works!" from the goddamn rooftops if they were ever to actually catch someone.
