I would have given you some points if I could. RackMonkey is really a good solution. Although I don't know if it scales to the point where questioner needs it.
We would have taken this software but there was only one problem. We have several devices (like e.g. firewalls) which are only "1/2 U". Meaning we have two devices next to each other. And this could not be represented at the time when we evaluated the software.
And as I wrote in my article I am only writing about this one. And I was not talking about "Windows Compute Cluster Server 2003" or the NLB feature.
And about the vmware solution: He could create a snapshot of the running vm then copy the disk file(s) over to the other server and then delete the snapshot again. This whole process can be scripted with perl and RCLI. He only needs two ESXi servers for this. And they can be downloaded for free. It is definitely not the best solutions but one that would work.
And yes, your solution is probably the best one for his problem.
True, sorry I did not write it that clear. I was only writing about the Cluster software included with Windows. Not about other applications like NLB included with Windows too.
I just wanted to make clear that Microsoft Cluster Server is a lot easier to set-up (what the questioner has seen correctly) but this is because you get a lot less. He would have to install and configure several other applications (like NLB) to get the same as he gets with Linux HA.
I want to give you some more information. Based on your visitor estimates I think you do not have a lot of knowledge about it. Because for this number of visitors you do not really need a cluster.
But now to the other stuff. Yes, Windows clustering is (up to Win Server 2003 [1]) a lot easier. But this is because it is not really a cluster. The only thing you can do is having the software running on one server, then you stop it and start it on the new server. This is what Windows Cluster is doing for you. But you can not have the software running on both servers at the same time.
If you really want to have a cluster then you need probably some sort of shared storage (FibreChannel, iSCSI, etc.). Or you are going to use something like DRDB [2]. You will need something like this too if you want to have a real cluster on Windows.
I recommend you to read some more on the Linux HA website [3]. Then you get a better idea what components (shared storage, load balancer, etc.) you will need within your cluster.
If you only want high availability and not load balancing then I recommend you to not use Windows Cluster. Better set-up two VMware servers with one virtual machine and then copy a snapshot of your virtual machine every few hours over to the second machine.
I can only recommend this one too... I have to evaluate a new trouble ticket system last week. And of all the open source products I found this one was the best.
We had OTRS before. OTRS is very good too, but really hard to install.
A friend is using RT. Now with the newest version the user interface looks really good too. And I think many problems mentioned by others are gone.
I would recommend Avira AntiVir [1]. It is free for personal use too. The was most impressed of the speed. I used Avira AntiVir all the time before I moved to Linux.
Actually this project is not the first one. Near Dubai they are building a similar city. So it is not only possible in china.
Btw. most ideas behind these cities can be used at other places as well (e.g. have many trees in the city because this is lowering the temperature compared to cities with a lot of asphalt. And if you have a lower temperature outside you need less energy for the air conditioner in the summer)
The website states clearly that you have to be in a group of 3 people. So it depends on how you manage the team. Everyone has only to work for 8 or 9 hours if you plan it like this. Then as well from the website: "However, the Hackontest developers may connect to their outside community through chat, SVN, wikis etc. thus enlarging their team size virtually in a unlimited scale." In other words those in the container could only be the team leaders/project managers and those outside program.
The link to the etoy.CONTAINER is not the best. The link goes to another project by etoy (which is based on the container idea as well). For more information about the containers you better visit this: http://www.etoy.com/projects/etoy-tanks/
I see another reason why this is a non issue. They can use an older version of samba which was released under GPLv2. They don't even need to switch to other libraries. If they want the can even fork samba.
Interesting idea. Maybe Wikipedia could be moved into http://freenetproject.org/ I think this would be a benefit for both projects if it is done right.
And there is a band with this name as well. http://www.irrlicht.ch/ Maybe a video clip belongs to VIACOM. I thinks as well, that a search bot accidentally listed it... And the person at VIACOM sent the list 1:1 to youtube without looking at it.
The person who wrote this article wanted to take the binaries provided by Debian. And this doesn't work. But if you take the binaries from MySQL you should still get support.
This Novell bashing is absolutely not necessary. All Novell is doing is releasing several plugins for Open Office and MS Office. Red Hat could have done this too. And those plugins are all open source and hosted on sourceforge.
I can't really tell which distro you should choose. But I can give you an advice to look around on http://www.linuxdevices.com/. There you have the best overview on what is going on in the embedded Linux market. (imho)
People often complain that the term OS is not true. I agree, but what difference does it make to a user if he/she is running the applications (the desktop) inside a browser or inside a pcAnywhere session? Or in a corporation network where all applications are running on a server with citrix software?
If those "web-OSs" would provide a good packaging system etc. then I see it as a competitor to Citrix.
But as long as I can't run VMware in it the term operating system is wrong:)

I was thinking the same. The names are too much Swiss.
I can only second totemo. Their product is really very good.
Another one I can recommend is http://www.seppmail.ch/en/home/ (If you have Blackberries then totemo is the better choice.)

Since when is it possible to have an Active/Active cluster? Definitely not with Microsoft Cluster Server from Microsoft 2003:
http://en.wikipedia.org/wiki/Microsoft_Cluster_Server
And as I wrote in my article I am only writing about this one. And I was not talking about "Windows Compute Cluster Server 2003" or the NLB feature.

And yes, your solution is probably the best one for his problem.
Please look at http://www.drbd.org/home/mirroring/ and the next chapter "Recovery".
I hope hope this can help you already little.

Well, it is an art group. They talk like artists :)
I was in those containers. It is not that special. In one container are work spaces and in the other (the one they put on top) are some beds.

You can still keep all your emails. But there is IMHO no reason to keep every sent message within one email.
The Pirate Bay is in Sweden. This article talks about Switzerland.

You should attend some geography classes again.

well, I would say it sounds more like http://www.zattoo.com/
Isn't http://www.stumbleupon.com/ already something like this?
They have a search functionality as well.
The article here on Slashdot is a little bit misleading. You still can get support from them. Them main part is this:s /policies-04.html#q04
