For servers a big draw back is that if you have to patch the kernel (or update it) you must reboot, but if the acual reboot only takes less than a second, users might hardly notice the downtime (you could reboot and keep a 99.99% uptime).

A big use of udp is in games, where you want to send out as much data as possible, and if you were to get a bad packet it has already happened and it doesnt need to be retransmited.
Would you reboot your server with the latest security updates if you made it into the netcraft top 50? Id build a new server and just keep the other one running to stay up top, i doubt that those old boxes do anything mission critical.
An example of using a firewall with in a jail?
There are plenty of uses. Normally one cant control a firewall with in a jail. So for instance on my FreeBSD jail account I cant control the firewall at all, it would be nice to block some annoying users (or just add some nice 75% packetless and 200ms extra latency) at the firewall level with out having to email the hosting company and asking them to add a rule to the firewall on the server that my jail is on. This is another step towards vservers being as fast and as featurefull as a normal dedicated server.
An alternative model, the jail [2] facility implemented
in FreeBSD, provides the ability to partition the OS into
multiple separated process groups with limited network
addressing space. The kernel prevents user processes
running in jailed environments from managing the
processes and certain system resources outside their
own jailed protection domain. All the jailed
environments share the same network stack; however
each jail is restricted to use a unique IP address, and
cannot interfere with other network traffic. Creating
jailed pseudo virtual machines in this manner has many
potential uses; thus far the most popular one has been
for providing highly efficient virtual machine services
in Internet Service Provider environments. It should be
noted that the standard jail architecture still uses a
monolithic network stack. Therefore the jails do not
maintain private instances of subsystems such as routing
tables, traffic counters, packet filters and traffic shapers
etc., so they must rely on the master OS environment to
manage those facilities.
The article says jails will have full control over a virtual stack. Soo... We can now have full firewall control under a jail, now that would make my life at LEAST twice as fun!
It makes sense to me that the real the real reasons for technology like this are to diversify our power grid. No one thing is going to make a huge dent in our power needs, but if we can spread out where we get our power from or even decentralized it then if one power plant goes out or has to cut back on production the whole thing will not overload and shutdown. So I would view this as just one step in strengthening out power grid.

Behind a NAT box? Fine. Then they'll just demand the identity of the individual using Kazaa with such-and-such a username at that time. Refuse, and you yourself are liable. That's pretty much how it works for ISPs already.
Yeah, the 7v trick is awesome i have made serveral cables to turn the 12v into 7, but you would have a hard time (as you said) routing the cables in your powersupply as the fans are only given 12v and gnd you would have to tap from the 5v rail which would involve some simi tricky soldering and warrenty voiding.
After the CPU fan the hard drive is the loudest, but since the Seagate Barracuda IV - the best hard drive ever in the world, which is freakily quiet - hard drive makers have been using the fluid bearing system and I guess most new hard drives are now as quiet as the Barracuda IV.
If by best you mean one of the quietest then you are correct, but it is also one of the slowest drives, compare it to any modern maxtor or wd (jb or bb) and it much slower.
In the article it mentions:
The water cooling technology can significantly reduce the noise level. Equipped with a microprocessor whose heat dissipation is measured to reach 75W, the NEC desktop PC can suppress noise level to 33dB (A) owing to a water cooling module inside it. As its level was measured to be 43dB (A) with an air cooling system, the noise actually has gone down to one-tenth.
Do they not realize that the decible is measured on a logrithmic scale?
Where would one look for some good solid infomation on what all these buzzwords such as "shadow copy" and "active directy" accually mean? Ive seen those horrid 2003 server ads, but what do these features accually do?
How many people still rely on ham radio? Why havent they moved over to something a little more modern? Does ham radio have any advantages over current technology?
Granted, you can take the source code, modify it heavily for your purpose (embedded routers in this case), and it might bear little resemblance to the parent OS. But is it still BSD or Linux then? How far can you alter it before it becomes a radical offshoot, and in truth, a different OS?
A different os? Probly not, maybe a new sub distro, but they are still most likely using a kernel that greatly resemebles (linux) or in this case BSD. They might have cut out, recompiled, or replaced some userland binarys (for size concerns) but its still not that much different. An rc script here or there, its still based strongly off its parent.
Somebody explain to me WHY the States gives hugs and kisses to the Geneva Conventions when they feel like it, and piss on them when it suits their own agenda?
I think you just answered your own question, they disregard the Geneva Conventions when it suits their agenda because they can.
Thats whats nice is for man!
nice -20 emerge -u world
or you could even make a dedicated nice xterm
nice -20 xterm
or a "mean" one!
nice --20 xterm
Nice keeps everything running nice and smooth!

Those computer could have been put to a much better use of folding...
They should at least have the serial header on the board so you can have a serial backplate if you wish.
You might want to have a chat with this guy. mk@neon1.net the writter of the minibsd tutorial.

...and how many times do you update you windows kernel?
