As I've matured as an admin, I've gotten away from the multiple services per machine on all platforms (Linux and Windows), simply because of complexity. If I update or need to reboot for one service, I take *ALL* the services down. But having single-purpose appliances, I don't have that problem anymore. Though early version of Windows made that behavior mandatory, it's still good practice to separate services.
What I'd really like is a nice server-based OpenVZ-style API that runs on Windows/Linux such that I can run my services as small atomicly-configured and managed bits. Oh but wait, I have OpenVZ and/or Xen to do that...
The downside of virtualizing 3 or 4 boxes onto one is that you lose some amount of independence. If you lose one machine, you lose all of the hosted VMs, so you absolutely need some VM host high-availability.
But the beauty of the VM approach is it doesn't have to be an all-or-nothing: build a two-three host virtual host network, and migrate (p2v) your hosts as time permits. In the end your utilization goes up, your physical plant costs (capital+runtime expense) go down.
I'm biased - I've used virtualization for the better part of 10 years now, and I'm 100% sold on it. I've used it for big businesses and small SOHOs. The SOHOs are where the biggest value was seen (VMware Server).
I'm with you on the cloud. While the idea of the cloud is amorphous, the value of virtualization is not necessarily. You can certainly go overboard (SANs plus multiple cluster interconnects and networks), but you can get a decent two host redundant configuration for virtualization for under $1000. It'll require you to use Linux and Xen, but it's definitely doable.
And the beauty of snapshotting is that you don't even have to have a test server for simple fixes. Take snapshot, apply patches, everything works, discard snapshot in 3 days. Everything breaks, rollback snapshot. Try *THAT* with real hardware.
Travel may be faster, and trade in much higher quantities, but aside from whimsical technological improvements, the very basics of life are not at all different from 200 years ago. Food, shelter, jobs, privacy, freedom of experssion and religion.
More thought should be given to the Framers, IMHO.
Except a halfway cheap xray will notice this giant hole in the scanner, and you'll get flagged for a hand-search anyway. Which is why I doubt we need such highly sensitive detectors at all.
That's the biggest question, what does it COST to have fancruft in wikipedia?
As properly edited documents, why couldn't the entirety of the Star-Trek universe be contained in Wikipedia? Hell, large portions of the Marvel Universe are so documented...
I say bullshit. You could write a book about Einstein. Why is every article about anything in Wikipedia less than 5000 words? (Maybe it's just the ones I've seen).
Hyperlinking is great, but I find that for most non-technical wiki pages, the coverage is cursory. Part of it's the No Original Research, part of it's also copyright limitations, but I think part of it is trying to stick to this ancient idea of what an encyclopedia is versus what a 21st century version would look like.
Owning a 400,000 house at 8% == $1.056 million over 30 years (not counting property taxes, insurance, and miscellaneous household expenses)
Renting a three bedroom at $2000/m: gets you living in that three bedroom for at least 528 months for the same $1.056 million. Now expenses go up (inflation and all that), over time, I'd expect you'd be at about break-even renting vs buying over 25-30 years.
And since that down payment can be used to invest in other vehicles, long-term, you'd almost certainly come out ahead if you had half a clue in investing.
Even nuclear power is solar power. All that Plutonium and Uranium and Thorium was of course born in the death throes of some supernova billions of years back.
It's one thing if you're a startup and have 20 people and no cash flow and can barely make salary to make 20 copies of WinZip with the hopes of true-ing up someday. It's another to completely deny the problem.
I've been in both situations (one a mega-corp with ostrich syndrome).
Declaring compliance by fiat - aka, "we don't pirate software, therefore violating the license terms isn't piracy" - is somewhat like trying to declare yourself a virgin when you're already pregnant. </quote>
In 2009, one of those is a logical fallacy, and the other is technically possible.
I'll leave it to the reader to decide which is which.
I don't know about that... I had that feature on my Palm Treo 650p... And IIRC it was provided as part of the Verizon default install package. I never moved it over to my 700p when I upgraded.:-/
I have poor Verizon signal in my house, and Sprint was just as bad when I was demo-ing the Palm Pre... well I took the Pre back (and am regretting it), so when I got Google Voice, I just knew I'd move to Skype for home service, and get a halfway decent sim-based phone solution. So as much as I'd love to get the Pre, I'm waiting on a Tmobile/AT&T Android phone I like.
I've had to chew through 4 Treo 700p's and even when they were still being sold by Verizon, I could never just "walk into a store with my broken one and walk out with a replacement." I always get mailed refurbs.
This is a failure of Microsoft to provide a decent way of extending Windows Update to 3rd Party vendors. Catch up with Linux already, will you, Redmon?
No its not. We had four 2.x hosts running VCenter 1.3 which would randomly hang every couple weeks. The ONLY solution was a hard power-cycle. They never could resolve the issue, saying upgrade to 3.x and Vcenter 2. Right. We're going to upgrade all 20 of our ESX hosts just because you can't resolve this problem...
Eventually we had to... retired the servers and the SAN it was connected to - problems never recurred. Great support, VMware.

I agree, If KVM belongs in the kernel, then so does OpenVZ.

As opposed to simply plugging in a 1U server, a network management cable, and a gigabit public network cable and two power cables.
Yup, I'll take that over a blade system any day. Nevermind wacky N+2 power-arrangements (like the IBM bladecenters) just to get true PSU redundancy.
You got me on the fiberchannel reconfig, though.
Are they really?

This is also the downfall I predict for the experiment that is StackOverflow.
I have no idea how Slashdot has survived 12 years, and that it's still one of my top 3 sites I visit after Gmail in the morning.

I'm with you. I think this overspecialization of society is potentially our greatest downfall. :-/

Thank you very much.

oddly enough, I've found that it's the couples that communicate, no matter the form, vs the silent/ignoring each other type, that last forever...
Of course if it's actual REAL arguing/fighting, you're doomed..

You can also use the Group Policy editor to do most of the same on a non-AD machine by editing the Local Computer Policy object.
I'd wager this is how Vista/Windows 7 got much of their improved security features.
Prior art by HP which used to do this in Pentium-based Netservers?
Granted real hardware, as opposed to software, but perhaps?
