To be more specific, this changed because MS announced way back that domains are not a security boundary anymore. Since anyone with admin rights to a global catalog can make changes to any object in the forest, they say all domain admins in the forest must be trusted.
Therefore, if there's a political reason to separate the two companies, they should each have their own forest. Setting up a forest trust (federation) allows you to assign rights to resources across the forest boundary without giving away the keys to the kingdom.
One more question: Why not just combine the two AD forests into one tree, with the student account domain as a child domain of the teachers' domain?
In the summary, the poster mentioned wanting to reduce the number of physical servers from two to one. There's no way to do that with active directory (unless you virtualize) because each DC can only handle a single domain. Personally, I think the server count just for DCs is a big problem with the design of active directory. If you had two separate but related organizations, to do things the "right" way you'd need at least six domain controllers (two for an empty root, then two DCs for each of the production domains.)
The "empty root" theory was dropped a few years back. It's really not necessary.
Also, two separate but related organizations need a single domain with two OUs. The ONLY reason to separate into two domains was to have different password policies, and even that reason has gone away with W2K8. You can assign password policies at the group level now.
So, for any infrastructure that doesn't need DCs at multiple sites, you'd only need two DCs for full local redundancy. You may want to add two more in a separate site if you want remote redundancy as well (or just one in each site if money is tight).
You don't really need to start scaling up to more DCs until you get into tens of thousands of users range.
We saw it up here in Canada; absolutely no one was willing to pay for incoming text messages - until EVERY SINGLE CARRIER started charging for them at the same time. Suddenly, everyone was willing to pay for them. Funny how that works.
Except that Rogers didn't start charging for incoming texts, only Bell and Telus. I don't think 2 out of 3 counts as EVERY SINGLE CARRIER.
Somehow, Bell and Telus still have some customers though...
You're going to want to put that into context *very* carefully.
No, I'm not. I was quoting someone else for reference only, so I don't think it's up to me to put it in context. Of course most of your points are valid, I just wanted to provide some stats for the original poster.
...as compared to a typical motor vehicle with two passengers which would get around 44 MPG per passenger.
I think you'll find that the "typical motor vehicle" has far less than two passengers. I don't have the exact number, but from my experience it would be very slightly higher than one.

Yup, I got one of these too. They were asking for ~$75 for a one year renewal of a.com domain. I think there was small print stating "this is not an invoice", but otherwise looked quite convincing.
I can see how the uninformed masses could easily fall for it.
Funny, I remember grade 9 typing being a prerequisite for computer courses, and thinking at the time how stupid that was. But it probably did more good for my career in IT than any of the high school computer programming classes I subsequently took.
BTW: You are old. Agreed. Grade 9 typing turned out to be the single most important and useful class I've ever taken. Touch typing makes everything about any desk based job infinitely easier.
I've got an LG Voyager and it's got the row for numbers. The upcoming HTC Touch Pro will have a full five row keyboard, with number row and space bar both in the right place.
I'm trying to remember when I last used an actual typewriter but I can't pinpoint it any better than 1982 or so... That would by my grade 9 typing class for me. 1988-89. Coming up on 20 years ago... damn I feel old.
Consider the fact that you can be arrested and convicted for carrying a gift-wrapped package into an airport. Also for just saying the word "bomb" or "hijack", even in casual conversation. Strapping some shoddy electronics to your chest is a really, really bad idea these days, no matter where you are. Not necessarily because it's illegal (it is illegal in an airport, probably not anywhere else), but it's incredibly stupid.
I don't necessarily agree with the laws in place, but that's not going to change the facts. If you go into an airport and pull any kind of stunt like this, expect trouble.
I wasn't referring to the "watch 1,500 HDTV channels simultaneously" bit, it was the "download a whole high definition DVD in two seconds" bit that I had a problem with. I stand by my assertion that their math is screwy.
They obviously didn't do the math before writing the article. Considering that 40 Gigabits per second will get you a maximum of 5 Gigabytes per second (ignoring overhead), thats only 10GB in two seconds. That's enough for a single standard definition DVD movie in two seconds. Nowhere near enough for an HD-DVD.
"A 128 bit file system can't ever be filled. (yes "never" do the math)"
I did the math. That would handle 3.4x10^38 Bytes, or 340 trillion YottaBytes (1 YottaByte = 1 billion PetaBytes, 1 PetaByte = 1 million GigaBytes). That's a very large number of Bytes, but I still wouldn't use the word never. I usually even try to avoid the phrase "never in my lifetime", but in this case that's probably a safe bet.:)
Note: I'm using the hard drive manufacturer's definition of *bytes here.
I'm using Firefox 2.0.0.1 on 2000pro and just checked the Walmart site. No problem at all. I found they sell "Idiocracy" for $18 and change.
Not that I shop at Walmart because I'm one of those "support small business" types. Has anyone else with Firefox, Safari, Opera and other browsers tried going to the Walmart site? Yes, the Walmart site works fine in Firefox. It's their music download site that doesn't work. Try this: go to walmart.com, click on the "Entertainment" menu, select "Music", then click the big gray "Music Downloads" button. That's when you get the following message:
We notice you're not using Internet Explorer. To continue, please visit this page using Internet Explorer 6.0 or later. I'm on Vista Ultimate with Firefox 2.0.0.1. It works fine when I use IE7 of course.
Ok, that's cool. And they're not my cars, I'm Canadian. We generally drive much smaller cars than the Yanks down south. We even buy our gas in highly taxed litres, just like you folks.:)
You just proved his point about no one noticing. They don't use the "Pentium" brand anymore. The latest generation desktop processors are referred to as "The Intel® Core(TM) processor family".
"it is, as an unrelated issue, possible to steal Windows, and such has happened."
No, it hasn't. Really. Sure, maybe a lot of people have had their licensed copy of the Windows CD stolen. I'm sure a lot of people have had their computers stolen, along with their licensed installation of Windows. There was even at least one incident of the source code being copied off of Microsoft's servers illegally. However, Windows itself has never been stolen.
Microsoft is the legal owner of Windows. They currently have it (the source and compiled binaries) in their possession. They have never NOT had it in their possession. Therefore, it has never been taken away from them, QED.

Forest federation takes care of the empty root problem quite nicely.

He probably means an iPod Touch
Rogers in Canada still does paging too.

I think you'll find that the "typical motor vehicle" has far less than two passengers. I don't have the exact number, but from my experience it would be very slightly higher than one.
Specifically for a Boeing 777-300ER:
Gallons/Mile: 6.077 .01665
Gallons/Passenger Mile:
MPG per passenger: 60.06
(from http://www.airliners.net/aviation-forums/general_aviation/read.main/2628781/)
Amtrak reports 2005 energy use of 2,935 BTU per passenger-mile[33], or 39 passenger-miles per gallon (from http://en.wikipedia.org/wiki/Fuel_efficiency_in_transportation#Trains)
Passenger airplanes averaged 4.8 L/100 km per passenger (49 passenger-miles per gallon) in 1998. (from http://en.wikipedia.org/wiki/Fuel_efficiency_in_transportation#Aircraft)
Wifi with WEP or WPA configured would be more reasonably comparable to a house with a closed front door. WPA if the door is locked, WEP if it's not.
Wifi without security is more like a storefront, with a sign out front saying "come in, we're open".
I vote for financial services. I've worked for a couple of big banks, and this story sounds like a perfectly normal project.
Anyone know where I can pick up one of those "Bang Head Here" signs?
Yup, I got one of these too. They were asking for ~$75 for a one year renewal of a .com domain. I think there was small print stating "this is not an invoice", but otherwise looked quite convincing.

As a Canadian, I volunteer to round them up, place them in burlap sacks, and drive them down. I'll meet you at the Niagara Falls border crossing.
What happens to them after is up to you.

You should also keep in mind that a US gallon is smaller than an imperial gallon. I just punched this into Google to translate for you.
1 (mile per US gallon) = 1.20095042 miles per Imperial gallon
therefore
18 (miles per US gallon) = 21.6171075 miles per Imperial gallon
The average mileage of American vehicles isn't quite as bad as most Europeans think it is, for this reason.
