Whoa ! When I change apache httpd server code, it says "Microsoft IIS server" or anything I want when I type "httpd -v". I guess it's the same for anything for which you have the source code;-))
More seriously, do you have any reference for "Linux is ready for up to a million cores" ?
Sources are always appreciated when you tell us something. I googled a little without finding anything on what you are talking about.
When we reach 1 million cores, we will need to rearrange the output of cat/proc/cpuinfo to eliminate redundant information;-))
By the way I just typed "make menuconfig" and it wiil let you enter a number up to 512 in the "Maximum number of CPUs" field, so the Linux kernel seems ready for up to 512 CPUs (or cores, they are handled the same way by Linux it seems) as far I can tell by this simple test. Entering a number greater than 512 gives the "You have made an invalid entry" message;-(
Note: You need to turn on "Support for big SMP systems with more than 8 CPUs" flag as well.
> and has mirrored 500 GB disks, which I think is essential for any home server.
I found that when the computer is ran with with no screen, the hard drives are what require the most power. Not surprising when you touch them and see how warm/hot they get.
I have two monitor-less servers, one has 2 X 500G drives in it while the other has 4. The one with 4 drives takes about 160 watts of power while the other with 2 takes about 80 watts of power.
I would suggest to look at alternative media to store your data (or more energy efficient drives) if you are concerned with saving power. You may also look at stopping the drives from spinning when not in use depending on how busy your server is throughout the average day but I do not know how well it works under Linux.
Also, if you live in a cold area where you need to heat your place, the heat dispersed by the drives will warm your house and make you save on heating bills. This is one of the reason I do not worry about this that much... I just warm my place up with the computers and this makes me save on heating bills;-))
When I was in school and later on specialized training, the teachers/instructors sometimes mentioned that a "true multitasking system" is preferable to accomplish the task they were talking about. I often asked them if Windows qualified and they wouldn't answer, but obviously, by their mimics, they thought no.
Windows 7 is just the same old thing improved. Microsoft would have to completely ditch their OS and rewrite something from scratch ($$$) to qualify as a "true multitasking system" and make it to server land like they have been trying to do since around 1999 or 2000. Just think about NTFS algorithm with regards to fragmentation. It is the same all over the place in memory/process management etc. All legacies from DOS which wasn't designed in the first place to be a "true multitasking system" which is needed for modern computing. Unix was designed from the start with those concerns in mind.
P.S. I use Windows for desktop and laptop mostly to ease dealing with the rest of the world but all critical business functionality/storage is ran under Unix. Serious stuff is also done on Unix through Xvnc displaying on my Windows desktop/laptop. It is uncommon for me to have X session run for a whole year. I still use XP but I will eventually upgrade to Windows 7 or better, I usually skip 1 or 2 versions;-))

2) Your machine gets faster because of the absence of network lag.
I did not think they would pick a customer computer to be the server. I guess if they do, they must pick one with the most horsepower so the answer could be 2, but still...

While at it, are you aware of any attempts or concepts ever made to distribute the server load across several gamer machines ? I would doubt this but then again; how would they prevent from disrupting the game when a gamer shutdown his computer (being the server) before ending the game. Passive standby servers ? Active-active servers (sharing the load) ?
In short, how advanced and sophisticated is the technology of hosting server on gamers machine without their knowledge ?

Google (at least addsense does for sure) for one makes requests (not all requests) faking browser headers to make sure that you don't do page cloaking. Other "stealth" search engines do the same (intelligence services, tools especially designed to artificially boost your web trafic, etc.).
"Unique visitors" are usually counted with a timeout (the lower the timeout, the more visits you get!) that makes you counted like 10 "unique visitors" if you visit a site 10 times in a day with enough time between the hits. Guess what most sites set their timeout to !
So you are saying "web stats" are exacts ? Do you sell publicity based on hits/unique visitors to your customers ? Do you keep your job based on the hits your site gets ?
Please note that I was using "web metrics" as an example. Another poster as noted that the example was irrelevant for SharePoint. I don't think so, I think this practice has spread all over the industry and if your competitors do it and you don't, you put yourself at a disadvantage.

Hmmm... locate doesn't allow you to search within files. What about using rgrep or grep -r ?
find is great too (but slower on the first run before results get cached by the kernel, if you have enough spare memory) when you need to know which files have been modified in a given period of time, which files take more room on the disk, etc..
I usually disable locate for security reasons, at least use slocate !;-)
I don't use Share Point and I don't especially like Microsoft but just to put things in perspective:
We all know (don't we?) that web metrics are inflated by mostly everybody (hits and unique visitors counting search engines as real users,.NET tags added to user agent just because you used windows update to update your computer, etc. etc.)
A good rule of thumb could be to divide any of those numbers at least by 2 to get a better picture of realty.

I am not sure I follow your logic although, the tuition rate the Quebec Universities get is the same for every student without regards for where the student comes from. The only difference is that the government pays back the universities for the difference they charge to Quebec citizen, so Quebec citizen end up paying less from their pocket.
Americans are not too keen on socialist measures but to be exact, you should have said: "If you want more US citizens to obtain degrees in these fields, have the government finance the US citizen students"
You should also have mentioned a well known "brain drain" problem with Quebec system: The smartest Quebec students get their degrees for almost nothing and end up leaving the country to work somewhere else so they never pay any income tax to Quebec to help finance the costs of their degrees for which the government paid 4/5 of its cost.
Foreigner often get their Quebec citizenship through marriage or other methods to study here for close to nothing and then leave to work somewhere else as well.
Unfortunately, that perception is fading, especially in the minds of people outside US. I do not think the former US president helped much in fixing this problem.

You are technically correct !
But in truth, the +12/-12 timezone is the same timezone with the dateline in the middle.
This image makes things a lot clearer:
http://www.worldtimezone.com/
Since GMT is 0 if we had +12 timezones and -12 timezones we would end up with 25 timezones ;-))
So +12 and -12 take the same space as as one unique regular timezone would take.
Yep, you are right, of course no two adjacent timezone have the same time ! Even if it"s not the same day on each side !
By the way, you can cross the 180th meridian (officially dateline with exceptions mentioned by another poster) without changing date :
Coming from Tokyo, you cross the line at 23:30 on say, October 21th, once the line crossed, you are now at 0:30, October 21th ;-))
Hehe... got you ! ;-)
I said most people were not used to this...
It is actually the other way around, you have to fly from Tokyo to Honolulu to land on the previous day ;-)
Your comment was nevertheless very interesting ;-)
Cheers,
It seems at least Slashdot is not behind, I think that I have noticed before that mod points are attributed/expired at 0 hour UTC, 4 or 5 hours before midnight EDT/EST ! ;-))
And don't forget the 180th meridian that came with it. When you cross the 180th meridian, you have to set your watch back/forward 23 hours !
Quite a few people are unaware of it ;-))

As wikipedia states ( http://en.wikipedia.org/wiki/American_Dream ) the American Dream seems to be a fading concept:
"In recent years, the concept of the American Dream as a national ideal has been studied by various organizations. The conclusions of these studies indicate that during the 1990s to the 2000s, a period of remarkable wealth for the U.S., an increasing number of people confess to having lost faith in the American Dream."
