The idea that "if it's out there, we would have seen it" seems a bit silly for any number of reasons.
Yes, that idea is silly. The actual Fermi idea that "if there was life out there it would have colonized the entire galaxy already, and we wouldn't be here asking if there is life out there" holds a lot more of water.
General Relativity doesn't conserve the total energy. The total energy of the photons of the Universe is reducing as the Universe expands, and the total of dark energy is increasing much faster, but we don't even know WTF that thing is, so this may not be usefull at all.
Why bother breaking into systems when you can reroute them into your private network and use MIM attacks.
Keep it in mind. Internet security is done end to end. The old telephony networs are dead, and even them weren't really reliable.
If you have sensitive data to transmit, you shouldn't even think about where it will go. Wherever it is, it is not a safe place, and your data must be protected.
The investiment in stocks (of finished goods, parts, everything, at the manufaturer, distributor, retailer), the risk that some products won't sell, the loses on transportation, and event he amount of money the governent gets to keep; all increase when the price of the product increases.
Won't deny one thing though - the hardware support from Apple, no one else comes close, not even remotely - which is sad. That whole "oh golly sir, it has a scratch and re-booted once on you?! Here have a new phone!" - that's good.
Well, I'm lucky in that I've never tried returning a phone. But, anyway, you can easily buy an Android phone by half the price of an iPhone with equivalent specs and quality... In the exceptional case that it fails, if the manufacturer doesn't accept a return you are still even.
Unlike older ion generators they don't produce ozone. The ions cause airborne particles to either fall to the ground or be neutralized (e.g. mould is killed).
It is very hard to ionize anything in air without producing ozone, and it is normaly the ozone that "neutrilizes" dust and kills mold. So, I kind of doubt their advertizing.
Anyway, it doesn't really matter. Any ion is equaly bad (as in "not very much", since there are very few of them). If it kills mold, you can be sure that it isn't very health for you to breath (but, again, concentration is everything).
Well, it's not. Most if it is generated near the ground.
But it isn't generated inside your house either, while the ozone from a ionizing filter is. Also, it's not constantly generated, leading to at most rare and fast expositions (ozone don't last for long), while that device leads to constant exposition.
All said, I have no idea if the ionizer is actualy harmfull or not (it certainly produces a very small quantity of ozone). It is not something I'd actively seek to be near, but it is also not something I'd avoid at all costs.
Well, ok. You seem to be confusing the amount of phones sold in a quarter with the amount of phones in use. The iPhone and iTab were kings of hill for long enough for the recent change in the market not make much of a difference yet.
Also, those stats are about a single site. One that is a siri source, if I'm remember correctly.
There is no such thing as "Linux Userspace". (Ok, there is a couple of scripts for installing and removing modules, but that's all, and Android runs them.)
If defaults were sane then it wouldnt be as important, but they NEVER are.
Oh, but that's because everybody has their own definition of what a sane default is, and is forever complaining that everybody else has crazy requirements.
But some things are positively insane. The default settings of KDE are a great example. I guess they want to showcase how configurable the DE is, so they force you to change every setting.
That's what the change into KDE 4 was all about. They added a layer that makes it possible to fork the interface without forking most of the code, gaining the flexibility required for creating all those projects.
Do you remember when they were promissing that KDE 4 would be set for the future (before the release of 4.0)? That was what they were talking about.
A small correction, but the end user focused software my MS is becomming less relevant. That's where most of the bugs always were, and that's exactly what people are not using anymore. Server software is also getting less relevant, but it doesn't matter on this context. Kernel and libraries are as relevant as they always were (ok, a tiny bit less).
What is gaining relevance now is the crapware that people must install because Windows does nothing out of the box.
I can't say that never happens, because it does... Mutually exclusive librares are already rare, you needing two versions of them at the same time... I've seen it like once or twice, never on a server (I've installed Linux way more times on desktops than servers, so that's not unexpected), and can be mitigated by choosing a stable distro like Debian or just recompiling the one package that is giving you trouble.
In my experience, it's way more common that a service refuses to share a port than library incompatibilities.
How do you move an NTP server from one physical machine to another? Without stopping it in between.
Well, NTP's cluster is called "pool". (Also, you can hack something with a shared IP...)
I am curious about this. Does "your datacenter" mean any datacenter, or specifically the AC's datacenter?
It means it is very probable that the GP's datacenter in particluar has it, because nearly all the datacenters have, and there is no reason to belive the one he administrate doesn't. I'm aware that is a low, but nonzero chance of he being an exception, and thus I'd be wrong.
Also, I'm not wiling to even look at the/. site for vunerabilities. I'll pass the dare.
But even better, if the pool is hosting 20 services and one is requiring more resources, typically you can subtract resources from other services, at least temporarily until you go find the powerful server to replace it. With zero downtime.
Thanks, that's another real reason for using VMs. They give you some flexibility here.
Notice that you should have zero down time anyway, that's not a reason for VMs.
Load balancing.... In a cluster of virtualization hosts, the virtualization platform can re-distribute virtual machines to keep the workload balanced.
Yeah, you can do that in any kind of cluster. You don't need to add virtualization for that.
Utilisation. With things like page de-duplication I can over-subscribe the virtualization hosts and use more memory than is physically available.
It can improve your memory usage up to the point (for a complete and perfect optimization) you'll be if you just consolidated your real machines...
Partitioning. You're quick to dismiss it with a wave of a hand, but if someone compromises a virtual machine running Apache, they don't automatically gain access to all the other services running in the other virtual machines.
Yes, there is some gain in security. In practice, however, your datacenter has a completely open set of doors (it always has), and you are focusing in closing a window.
Point-in-time scaling.... Who has physical hardware just lying around waiting to be used anyway? Once the peak has passed I can turn the virtual machines off to save resources.
You mean, you don't have extra resources available, but you can spin up a new virtual machine anyway, and it will be able to handle the extra demand?
For little boxes that deal with DNS, time, etc - put them in amazon.
besides the NTP problems, also make sure to write on a piece of paper the IP of every computer on IT, then put it on a wall.
When you have internet problems and nobody is able to get any work done anymore because all of the light services don't need to be at your site, you'll need those addresses for the LAN party.
NTP is not real-time, so a few ms here or there of delay is not a problem.
A few ms on incomming and outcomming lags won't hurt it at all. A few ms on incomming lag without a few ms on the outcomming lag (like what happens when your VM is sent to swap) will completely destroy it's accuracy.

Well, I still don't get this very well...
General Relativity doesn't conserve the total energy. The total energy of the photons of the Universe is reducing as the Universe expands, and the total of dark energy is increasing much faster, but we don't even know WTF that thing is, so this may not be usefull at all.
In any democratic country, you have the right of free enterprize.
It seems that in Gabon, one doesn't. Well, it's their choice, and their problem.
NVidia does have a wrapper. (They had to, to comply with the GPL.) They still can't make a driver that'll work.

It's Android. Android is Linux from Google... So, yes.

As they are organized now, Apple and MS have a common enemy: Linux.
Ok, MS will backstab Apple removing itself from the aliance some day. But I doubt they'll make it so public.
Well, I'm lucky in that I've never tried returning a phone. But, anyway, you can easily buy an Android phone by half the price of an iPhone with equivalent specs and quality... In the exceptional case that it fails, if the manufacturer doesn't accept a return you are still even.
Because its chinese division will be dead within a week.

Were you thinking about the GNU userland?
That. At the same exact moment, Apple (with all its strategies) is begining to fall. We'll see if MS manages to out-Apple Apple.

That's why you use clusters.
Now, why are you talking about that in a thread about virtualization?
