Nor are they "isolated". All of the blades connect to the same backplane.

And moving VM's between individual blades is a hassle unless you use some form of shared storage. Which makes them even less "isolated" but more redundant.

This reads more like he just wanted to show off that he calls blade servers "dense isolation".

So is it better to have a bunch of isolated servers which reduces the VM domino effect in exchange for increased hardware maintenance? Or just a few massive servers and be ready for the 4 am call to replace a CPU at any given moment?

VM is not magic. Also look into "fail over".

If you have to be called in to replace a CPU at 4 am then you have not planned correctly.

One hope is that the patents look good to the prospective employer on a resume, but I don't want them to take the existing IP for granted as part of the deal.

If it is not part of the deal then leave it off your resume.

My question is, how should I treat licensing of the patent as a topic with respect to the topic of my employment?

I think you are confusing two different situations in an interview situation.

1. You working for a company.

2. A company licensing your patents.

Leave the patents out of the process at this point.

The summary also seems to have left off the critically important TIMELINE.

The "weapons" that were "found" were manufactured and abandoned in the FIRST Gulf War. Back when Bush SENIOR was the President of the USofA.

So the troops in the SECOND Gulf War (Bush Junior) were being exposed to hazardous chemicals that were 10+ years old. THAT is what is/was being covered up. Our troops were working in/around hazardous waste disposal sites WITHOUT proper equipment or training or supervision or follow-up.

There are not any "WMD" being "found" in Iraq now. It's hazardous WASTE.

ISIS (stupid name) does not have "chemical weapons" from that. They have chemical waste that is a health hazard. No GA, GB, GD, VX, or anything like that.

You cannot boycott them while they still control the last mile (the connection to your house).

In order to take that control from them, people have to be willing to vote to have their local government install/maintain/tax a local network as part of the infrastructure.

Then the local government can lease connectivity to whomever wants to offer Internet service. If Comcast is charging extra for a service you want then you can go with a different option.

The core problem is that security has many different approaches.

A password manager is great ... as long as it is available to you on all the devices that you use to login from. Which makes it vulnerable to being cracked when one of those devices is cracked.

And that isn't even addressing things like the recent rash of credit card cracks being reported. Even if you keep YOUR password secured the attackers can still attack the system when you use the secure information.

Instead, the focus should be on the knowledge that you will, eventually, be cracked. At least partially. So be prepared to mitigate the damage done at that point.

Too many people have too much access to your information without the personal incentive to keep it secure. Or the knowledge of how to secure it. Password managers are an improvement in many scenarios. But so is writing your passwords in a book that you keep at home.

In a pinch, yes a troll will go after your default WASP male. I once saw a troll reduced to attacking someone for being Canadian. (!)

Or Jewish. Or gay. Or black. Or of a different political party. Or with a different opinion on a subject.

"Trolls" (they aren't trolls, they're ass-holes) will attack anyone for anything that the ass-holes do not approve of.


The ass-holes are not attacking women because the ass-holes are misogynists. The ass-holes are attacking because that is what ass-holes do. Their attacks are phrased in misogynistic terms because the target is a woman.

Okay, that made me laugh.

But that requires that the average person trust someone they can't even name with keeping their money safe. And the money is just a bunch of zeros and ones. If the "hackers" can take your real money can they take your imaginary money?

Will the government take your real stuff because you got imaginary money from a "terrorist"?

Will you end up in court one day because your kid is accused of sharing a song and now you owe $50,000 in penalties?

The benefits of technology are not being evenly distributed. But the risks certainly are.

It's a ROUTER. If the physical link is up then try pushing packets through it. That's all.

If you want to show connectivity to a specific site then show that in the diagnostic page on that router. But keep pushing packets.

I spent 7 years in the army. Yes the focus is on following the manual(s) for standard tasks. And we have a LOT of manuals.

Kind of like the ISO 9000 stuff in the civilian world.

But if they are any good then they should be documenting HOW they're doing their job. And following those same procedures every time.

Part of the job is the expectation that you will be replaced. And the job will still need to be done, in the same way, by the next guy.

NOT following the manual means that the next guy will need time to come up to speed on how you did it. And the unit might not have that time.

Look, I explained it more than once including how energy is conserved. I can't do more than I have. You have to figure out for yourself.

No. You've claimed that it will happen. That's all you've done.

The Laws of Thermodynamics say that the energy has to go somewhere.

Moving the molecules further apart in space does not reduce the energy of the molecules. Without convection/conduction the molecules can only radiate that energy to lose it.

That's physics.

There is no energy lost from expansion of a relatively dense, higher temperature plume of gas into a vacuum.

There is energy lost if the molecules drop below the background radiation level in a few seconds. That is what you are claiming.

Where did that energy go?

Appeals to physics don't work when you are wrong as is the case here.

There is no "appeal" here. I'm showing you how the Laws of Thermodynamics show that you are wrong.

The energy has to go somewhere.

You cannot explain where the energy goes. So you just keep repeating that it goes away.

Two rocks that are 1,000 K at 1 meter apart do not cool to 500 K because they move 2 meters apart.

That is physics.

You don't understand what temperature is.

Not only do I understand what temperature is, I also understand how it is different than heat. And how each is measured.

Which is why I keep pointing out to you that two rocks that are 1,000 K at 1 meter apart do not cool to 500 K because they move 2 meters apart.

And that is what you are claiming.

1) Stealth is not perfect invisibility or undetectability.

Only on Earth. In space it is because in space there is line of sight to everything.

2) Everything is detectable with sufficient resources thrown at the problem. Even the presence of a "horizon" doesn't change that.

You are wrong. The presence of the horizon means that non-perfect stealth works on Earth. But not in space.

3) It is not actually that easy to detect things before they get close enough to cause you problems in a military sense.

The instruments available today can detect the background radiation of the universe. That is around 3 K. And it can do that at billions and billion of kilometers. Unless you are claiming FTL or reactionless drives then you are wrong.

4) Examples given of the supposed ease of detecting stealthed objects are terrible and there's a lot of ignorance of physics and routine tactics of stealth.

So your definition of "stealth" is "invisible to people who are blind". That is not stealth. That is blindness.

5) If you're going to appeal to physics as the basis of your argument, you need to get the physics right.

The Laws of Thermodynamics show that you are wrong. The energy has to go somewhere. Two rocks that are 1,000 K at 1 meter apart do not cool to 500 K because they move 2 meters apart.

You can claim that the exhaust will cool down to below the background radiation level of the universe within seconds but you cannot explain how that would happen.
