The pressure drop is much, much more than 8.5 psi.
As I said in a previous post, the wind velocity over the opening lowers pressure much, much lower than they would normally be than if the aircraft wasn't moving and you just had the different pressures due to altitude.
Think of an aircraft with a door open, either a side door to release parachutists, or rear cargo door on a Herc. The pressure difference creates a relative vacuum from inside to outside, because of the wind speed caused by the forward flight. And that's at speeds that are easily 1/4 of the speed of a commercial airliner.
And the speeds of those airliners are closer to 400 knots, not 700mph, which is almost mach 1.
Mythbusters does get a fair bit of stuff wrong, you know.
And it wasn't Hollywood that put this into my head, it was my Air Force flight instructor.
Just to add to this, and to see the theory at work, you can do this simple exercise (like we did at flight school).
Open a can of some liquid. Coke, Pepsi, whatever. Get a straw, and cut it so that the bottom end can be submerged a bit in the liquid, and the top end is about an inch over the opening in the can. Blow across the top of the straw. Liquid will come out, even though you're at the same altitude.
It's got more to do with the speed of the aircraft than it does the altitude.
The airspeed across the open/busted window creates a huge pressure differential, basically sucking the contents out of the space (in that instance, the cockpit).
If you've ever seen the small size of the window in question, and realize that the pilot was sucked halfway out of it, you might understand the level of force we're talking about here.
That's not the case at all. They're fighting like hell to run power to the cooling systems to bring them back online. The brief withdrawal of workers was due to a temporary spike in radiation.
And the US and other nations have sent people there, on site, to report on what is going on. No sats required. Hell, the US Military has helped put out some of the fires, so they are RIGHT THERE.
The Emperor went on TV to ask the world for help and patience while they work on the problem. China has been asked for help in supplying boron to help cool things down.
Go follow the BBC News coverage for some real information on what's going on, they seem to be doing quite well at providing it.
The Oracle improvements, for the most part, are actually kernel level modules and services that provide the required functionality to facilitate their database clusters. They basically provide the inter-node communication and shared block access management services among other things.
I'm a long-time Oracle DBA, and could care less about this little war. I just know that it pays the bills.
They weren't jailed for a social website, they were jailed for stealing and selling credit card numbers for millions of dollars and had offshore bank accounts.
This has nothing to do with terrorists winning, and everything to do with people who are friends and associates of those that are in power, taking advantage of a fictitious threat scenario, and cashing in on it. It's greed, plain and simple.
Idiots are getting more and more power granted to them, and making more and more cash in the process, all for dealing with this "threat" that they've manufactured. They will do anything and everything they can to perpetuate it, as long as they retain and grow that power base and make more and more money.
Security Theatre relies on keeping the public ignorant of what the real threats are, and of the proper ways to deal with them.
And the morons in charge are making laws to protect themselves and keep it all going.
These guys aren't doing anything wrong... they're just editing some pages. The Wiki admins SAY they're libelling people, etc., but since when is it Wikipedia's responsibility to handle that for those that have been wronged?
If they're claiming illegal activity, then follow legal means to take care of it. They can't just say "they're doing illegal shit so we should take some vigilante action to shut them down".
Again, I'm not agreeing with what these vandals are doing, but I'd never condone Wikipedia using their popularity to influence an ISP. That's just a bully trying to get their way. At that point they stop getting any and all support from me.
Wikipedia apparently has a system or process with a few holes in it, in that they are relying on people being good and doing the right thing. That is flawed. It's not up to Verizon to deal with it, it's up to them to adapt their process to handle it. Either that or wait until the vandals get bored and go away.
Mind you, a story on/. will probably not help it go away any time soon. If anything, you can expect to see a bunch of new "vandals" start fucking with them any time now.
If the vandals are doing something illegal, then go ahead and follow the legal procedures to get it stopped, which would probably include subpoenaing Verizon for the identity of the vandals and going after them directly.
If it's not something that can be handled in the courts, (being a dick hasn't been made illegal, last time I checked) then Verizon may well open themselves up to a lawsuit for helping Wikipedia with this "wrongdoing".
If it's not illegal, then they'll probably have to adapt their process to take care of the problem.
And I'd be very interested to see how many good edits or entries were being made from that block of IP addresses. They may well be cutting off their leg to cure an ingrown toenail.
The man was the network administrator; he was authorized to make decisions about how the network is accessed, it goes along with the job. Who was he to get permission from, himself?
Oh please...
You have NO way of knowing that it was his decision. And it's a government... odds are that he was NOT allowed to make that decision.
I know that in my shop, the network admins do not have that kind of autonomy. They can make all the recommendations they want, but it's not their decision.
For all we know, he may have asked his superiors for permission and they failed to give it, and he went ahead and did it anyways.
I've been doing app development for years, and work in a few OS projects myself.
I'm quite familiar with the various licenses, etc., required.
I've helped vet those licenses for Government implementations, as well as pay lawyers to draft contracts for custom licenses I need for my own software product.
The last thing I wanted to do was go about and mass download and extract any/all Java/Apache/JBoss libraries and licenses.
It was nothing but a colossal waste of time for everyone involved. It's just the client ended up paying for it.
Actually, I had assigned resources to the project at the client's request, so instead of having them pay for those resources as they sat idly by doing nothing, or ME having to pay for them to do nothing, I put them to work doing the only work we were allowed to do on the project.
AS REQUESTED BY THE CLIENT.
So yeah, it might have been a dickish thing to do, but I did my best to NOT do it.
Just to clarify some things, as it appears you're not that up to speed on how custom development contracts work.
This was a custom development job. We are talking about using core libraries, not finished products.
We were about to start with the discovery and business analysis phase of the project, as agreed to by the President and the VP that was championing the development.
We still didn't really know what it was that they needed us to build, but they had me spin up resources to work on the job so that we'd all be in the up-front meetings and be able to hit the ground running.
We didn't understand their business requirements, their budget, their limitations, timeframes, NOTHING. So we were in absolutely NO position to even start discussing what specific libraries were going to be used.
We were on a tight timeline (when aren't we?) and literally the day before we were to fly to the client, the lawyer inserts himself into the process, and raises a huge red flag to the president, and stops everything, demanding to not only proof-read the licenses, but to approve them before we use them. This was before our first BA meeting.
I tried to explain to him that we were in no position to understand what libraries or OSS we were going to use, because we had to move ahead with understanding the business first, but he refused to believe that.
I tried to talk to the President, but he had faith in the lawyer (his son-in-law), and refused to listen to us. The VP understood our situation, but his hands were tied.
I told the lawyer that we'd work with them on ensuring that all of the licenses that were attached to any software we were even thinking about using would be vetted and approved by him, but it'd be on an "as we figure out we need it" basis.
We didn't even know how they were planning on using the software at this point (internal use only, public web site, shrink-wrap, etc), so we didn't know what licenses were going to fit anyway.
He REFUSED to listen to reason, and claimed to understand application development better than we understood the law, and made a flat-out demand for the information.
I very clearly warned him of the unlimited scope of his request, and he said he didn't care.
I'd also spun up resources to start work on the project at the request of the President and VP, and there was no way in hell I was going to let them sit idle as a result of this, so I put them onto the task that was clearly demanded of me.
So yeah, I WAS trying to be a team player. I tried to educate the client about how to reasonably address their concerns, and how it was too early in the process to do so.
I also offered to just provide them with the major licenses out there that were the standards (GPL, Apache, etc), and he said "no, I need specifics".
So yeah, this lawyer was an idiot and an asshole, plain and simple. Condescending to boot. The fact he was working on getting his MBA might also explain a few things.
But I did everything in my power to deal with it in an effective manner in order to get the job done as effectively and efficiently for the client as I could, but he refused to allow it.
And I refused to take a 2 week hit on paying for my subs that would have sat idly by while that crap was worked out.

I'm also impressed that the investigation was done so fast and the apology given as quickly as it was.
That's why OS X Lion will be available on USB thumb drive for $69 next month.

Is it a coincidence that the last modified date on the PDF is March 31?
You know... as in the day before April Fools?
If that were the case, I'd be even more scared... who would have thought the FBI had a sense of humour?

Same concept here, but with 400+ knot windspeed.

Dude.
Totally true.
Really.
Yeah... I don't think he knows that censorship doesn't mean what he thinks it means.
No, I'm Canadian, hence the "here's my two cents worth, Canadian" signature.
And you're a fucking moron.
Wups.... that might not have been nice enough to convey the proper level of Canadian politeness.
My bad.
This isn't censorship, it's a corporate policy decision. Big difference.
This is them determining what items they want in their catalogue.
They have no requirement to put everything that exists in there.
You might want to buy better textbooks.

The real terrorists are running the show.
Again... .cooperate with WHAT exactly?

As opposed to going to the local Starbucks and using their Internet. Or scarfing any other source of non-Verizon internet access.
I highly doubt that someone going to this much trouble to cause them problems is going to stop the first time he runs into a simple block like this.
I guess I should have reworded my response to "adapt their process to something that will effectively take care of the problem".
This seems silly to me... why would Verizon care?
If the vandals are doing something illegal, then go ahead and follow the legal procedures to get it stopped, which would probably include subpoenaing Verizon for the identity of the vandals and going after them directly.
If it's not something that can be handled in the courts, (being a dick hasn't been made illegal, last time I checked) then Verizon may well open themselves up to a lawsuit for helping Wikipedia with this "wrongdoing".

As a Canadian Citizen, I'd just like to say to the EU...
"Go fuck yourself."
That is all.

It was nothing but a colossal waste of time for everyone involved. It's just the client ended up paying for it.
But you planned the project ahead of time right?
No. We were about to start he business analysis phase of the project... literally step one.
We were totally in the dark about what they needed, technical/business requirements, etc.
All we knew is that it was going to be an Oracle-backed Java distributed app running on Sun.
And I'm not even kidding. That was ALL we knew.
A good lawyer has common sense and a sense of situational awareness.
This one had neither.
He refused to believe he was wrong, and we did exactly what he asked of us.
In the end, we gave him just enough rope to hang himself with.
He just had to take responsibility for his actions.
Actually, I had assigned resources to the project at the client's request, so instead of having them pay for those resources as they sat idly by doing nothing, or ME having to pay for them to do nothing, I put them to work doing the only work we were allowed to do on the project.
