Buy quality parts, and everything should be OK. Don't expect a $300 emachine to last out the year.
A few tips:
RAID 0 (mirror) your hard drives. You will have hard drives fail.
Buy decent drives. I've had bad experiences with Quantum and Maxtor, and I've been happy with Seagate and Western Digital, but YMMV.
Go overkill on cooling. Fans fail more often than hard drives, and a dead fan will heat up the case, and can take out the hard drives.
That said, watch the fan on your power supply. They go out frequently.
Check the fans on your CPU too. They also go out frequently.
Be sure to buy a good NIC. A bad NIC might cause strange problems that are nearly impossible to diagnose.
Buy a cheap video card. You won't be plaing Doom3 on the server.
Backup to a USB hard drive.
If you don't need a UPS, make sure you at least have a surge supressor. On phone lines too, if you use them.
Servers have more RAM than desktop systems for a reason. Without knowing specifics, it's difficult to tell if you need more RAM, but bear that in mind. Web servers might cache.asp files. File servers don't need much RAM. Mail servers with antispam/antivirus stuff use quite a bit of RAM and CPU. Database servers cache everything and are CPU hungry.
Dual CPUs are a godsend. Sometimes an application will peg the CPU. This often makes the server appear to be hung. If you have two CPUs, only one CPU locks up, and usually the process eventually finishes, and you won't even notice.
Rackmounts exist for a reason. They save a lot of space. Rackmount cases are a little more expensive, but they can be worth the money. YMMV.
That said, dual CPUs and rackmount cases are a luxury, and if cost is that important, you can skip them. And make sure there is a process in place to check on the health of the server. Even waving your hand behind the box once a week to check how hot the PSU exhaust is can save the business a lot of headache. (Hint: if no air is blowing, replace the PSU, and check the HDDs to make sure they're both still working.)
Also, be wary of Dell. They use non-standard power supplies, so if your PSU goes out, you can't hop down to the local computer store and buy a replacement.
Ah, but they're charging for employees who don't use the software too. Actually, that's been done before. They've added charging for employees who don't even use a computer. I believe that is what is "innovative".
Yes, I mentioned that already. "(otherwise, you could have just made it a function)"
Also, code frequently gets copied from project to project. That leads to some interesting ideas regarding open source being a pool for software bugs to evolve in. What would they evolve into though?
It's technically feasible, even easy. But as a matter of policy, I remember some places saying the didn't want you doing it. I haven't been able to find anyone saying anything about it now.
Some dynamic DNS providers don't allow CNAME records, which is what you'll be using if you want your own domains to point to your dynamic DNS domain name. ie, your users type http://www.example.com, and www.example.com is a CNAME pointing to example-dyndns.example.net or whatever.
What's worse, is how many times have you copied & pasted a section of code? Afterwards, you probably modified that bit of code slightly (otherwise, you could have just made it a function).
Social insurance databases - Information about specific people should be private
Driver's license db's - Information about specific people should be private
all police investigations, regardless of whether charges are laid. - Information about specific people should be private
medicare payment treatment and payment records - Information about specific people should be private
nuclear missile plans. - National Security
the approved architectural plans for that nice, bombable Hoover Dam. - Sure, this should be public knowledge. Not to mention this argument is flamebait on its face. Why do you insist on mentioning it's bombable? A terrorist could find the weak points without the plans.
tax records of all sorts - Information about specific people should be private, corps on the other hand should be public.
how the governement recognises you, as opposed to someone pretending to be you, and gives you access to your own information... - Information about specific people should be private
military supply orders and troop movements. - National Security
Also, the last argument is a strawman argument. The point being argued is that information should be free, not that it should be free in real-time. (Although that would be nice, if it's technically feasible.)
Since the dropline win32 GTK runtime distribution is no longer maintained, are they rolling their own? They have a standalone GTK installer download, but where did it come from?
Didn't MS do the same thing when they bought NCSA Mosaic? They offered profit sharing to the original developers then gave away the MS product (IE) for free.
ITYM Spiderglass, although Mosaic was involved too. Wikipedia has more than you ever wanted to know about it.
http://en.wikipedia.org/wiki/Spyglass The arrangement for the licence was that Spyglass would receive a quarterly fee plus a percentage of Microsoft's revenues for the software. Microsoft subsequently gave Internet Explorer away for free, and thus (making no direct revenues on IE) paid only the minimum quarterly fee. In 1997, Spyglass threatened Microsoft with a contractual audit, in response to which Microsoft settled for US $8 million.

The halting problem effectively won't let you prove the robustness of arbitrary code. You may be able to prove a subset of code to be robust, but I don't think you'd be able to do anything interesting.
If you use bit torrent, or some other type of swarming P2P app, SP2 limits the number of connections you can make per time period, and slows things down tremendously. Technically, it's there to slow down worms. Anyway, here's a third party patch to fix it: http://www.lvllord.de/
Jon Postel passed away October 16, 1998, so I doubt there's much that the ??AA can do now. Incidentally, here is the initial RFC for FTP, which gives credit to J. Postel.
Here, in Florida, on the gulf coast, residential electricity is:
$0.040470 per KWH for the first 750 KWH
$0.049770 per KWH Over 750 KWH
Plus
$0.037500 per KWH Fuel charge
Then there are various taxes and fees:
$5.25 Customer Charge
1% Gross Receipts Tax Increase
6% Franchise Charge
7% Utility Tax
And finally, there's a $3.00 "On Call Credit" because they can turn off our AC during hig demand. They reduce this credit if you don't use enough electricity.
Also, quite a few stories require that the spacecraft be a certain distance from the gravity well of the solar system before they can use their FTL engines.
After hearing about the problems people had getting AOL to cancel their service, I came up with the theory of getting terminated for a ToS violation, on purpose. Never had the chance to actually test it though.
(Yes, I'm sure I wasn't the only one to come up with that idea.)
My parents live in a gated community. However, all of the roads are public roads. So, the times when the guard is there (about 7PM-10PM weekdays), all he can do is wave to people. He's not allowed to stop people, because it's a public road. They do have cameras that record everyone entering and leaving, and that has been used to help investigate crime, but that's entirely different. Incidentally, there are celebrities living in the same gated community.
OTOH, I live in a cheap, but very nice apartment. The apartment complex is entirely private property. The guard stops anyone without a sticker, and asks who they are here to visit. Then they write down the license plate number, the time, and who they're visiting. Not terribly effective, but slightly better. You'd have to actually pull out a phonebook to get the name of someone living in the apartment complex. (Or you can just say you're going to the rental office, during office hours, of course.)
Both places have regular security patrols. They're more frequent here though. Both places have almost no crime. In conclusion, these two gated communities are more about appearing secure and catching people after the fact, than being secure and preventing the crime in the first place. But that deters enough criminals to be worthwhile. And the person who left the death threat probably could be found quite easily, unless they happen to live in the community, or know someone who does.
Virus writers will frequently submit their own virus to the AV companies, to get it listed in the AV software. They don't release it into the wild, out of ethics, but they get some ego gratification and acknowledgement. When AV companies claim they detect a huge number of viruses, most of the viruses they detect have never been seen in the wild. It's a good thing too, as most viruses in the wild are very simple things. Some proof of concept viruses can be extremely hard to detect and remove.
Get one of those "1 million email adresses" CDs they keep emailing me about, and check each one to see if it's in the list.
What is the expected benefit of "These files can be queried to see if they contain a given email address, but they can't be reverse-engineered to reveal the list of addresses used to construct them. " again?

Have you tried dynamic dns? P2P seems like incredible overkill for this problem.

Just an issue to be aware of.
Thank you! I shall look into this, and hopefully it'll work with our project.

Then there are various taxes and fees:And finally, there's a $3.00 "On Call Credit" because they can turn off our AC during hig demand. They reduce this credit if you don't use enough electricity.
In short, it boils down to about $0.10 per KWH.
