This actually goes back to a research project at DARPA last year. They had two networks, and IPv6 network and IPv4, and a team of network admins to work on each one. Turns out the IPv6 team was slower, because of the length of IPv6 addresses. Apparently it took that much longer to write down an IPv6 address, or read it off to someone over a phone, or key into a Blackberry. People thinking they could remember an IPv6 address while walking across the room also introduced several errors into the configuration on the IPv6 network. This would of course result in less work done per manhour and therefore increases the cost of a unit of work given the same amount of workers. A quote from an Admin on the IPv6 network:
"OMFG, for the last time, did you say two zero zero one colon dee five six see colon zero one one two colon five ef bee three colon nine zero zero zero colon colon one colon nine... cause I still can't ping it! Oh wait, typo! No, it's still not working... DAMN!"
Having flung a few pizzas in my day, here is an explanation for what you saw. You get on your shift with all the other pizza flingers. A call comes in from the base. It's your lucky day, YOU get to go on base. You get the get the customer's pizza, drive, go chill at a friends house for a few minutes, then drive to the base entrance, usually the only one where civilians can get on the base. You park, get out, show ID, fill out a form, yyy, get a pass, get back in the car and proceed to deliver the pizza. Takes about 5 minutes.
But now you have the pass, and lucky you, you get to take all the Base deliveries for the rest of the night! And when you take your next delivery to the base, you go to the same gate, the guard sees your pass, and waves you through. Nothing sinister going on here, though there are obvious security holes.
One problem I see with this is if there are say 5 or 6 movies and two or three games at one time. Do you need level 3 of the game to be able to play any/all levels after level 3? And if there are 5 or 6 movies at once, and ten pieces to a movie, what are your chances you will get all pieces of the movie you want? And how will you feel when you get three meals in a row and you aren't getting the pieces you want, or dupes of existing pieces.
Most likely, the kid will just go home, and go visit www.mcdonaldskeys.com, and get all the codes at once. It's just the high-tech way of sharing pieces/codes with your friends. But MickeyDs could make you open an account when you first start using the system, then they can decide which pieces to give you for each code, and the code expires immediately after use. There goes sharing. Bonus to them if you at least get to pick the movie it's from. And I'll just bet the order of pieces for a 6 part movie is:1 3 4 5 6 2. D'oh!
I seem to recall that mercury has a fairly low vapor pressure... it's doesn't want to evaporate at room temperatures. It's happy just being a shiny liquid blob.
Unlikely, most I have seen seem to be a hacked servers. I saw a log file on an infected PC, I connected to the same server and issued the same commands, but by the time I got there the jig must have been up, not the same PCs/output in the channel. Meaning, I issued the same commands but did not see the pages and pages (and pages and pages and pages, literally thousands) of entries as in the log file of IP addresses and entries like 2K10234 and XP11442. Strange thing is the "IRC" server was still running. I say that cause the commands were IRC like but not full blown RFC 1459. I sent a note to abuse@isp.com. Maybe the author got his list and was covering his tracks, but the goods were already in a log file on the PC. Again, just noticed out of the 500-700 connections open connections (netstat -an |find "ESTAB") on the infected PC one was not to the viruse's vector port, thought I would check it out... took several tries to even get to the same channel. I had to join one channel and then issue a command to join the second channel to even try. Can't remember which worm it was (not sober), but this was a few days after it was announced and thought I would sniff to see how prevalent it was. Odd. The virus descriptions say, "opens a backdoor on port xxx," and I would just try to connect to port xxx after I got connections, sometimes you just get a c:\windows prompt. Very scary, glad I know how to keep my win pc up to date, and run linux otherwise. And I consider that to be an invitation of sorts, as in, "I'm sorry, were you trying to tell me something? Were YOU trying to hack ME? YOU connected to ME. I am only looking out for my own security here."
I really do the echo something > notice.txt into startup folder, hoping the person will take action and realize they are infected... who knows what good that does. I am also a staunch privacy advocate, so nothing malicious (flame-suit on) from my end. mostly dir c:\windows\system32 |find "" to look for recently installed malware. I could care less about your files. That was how I found the log file that had what looked like a complete connection log to the IRC server. Too bad there are not more good commands in windows command shells (usually a virus opens a socket to cmd.exe) or I would kill and clean up and reboot, or even ftp down the patch, not like MS supports that though. (God the good old days of pre-retirement) This happens in internet time, not human time. If someone was really malicious, there is really no way even hundreds of humans could stop it. I take that back, a good hacker (in the MIT sense...) could reconnect back to the machine and issue some commands to shutdown the proc and stop the scanning, but again you are limited to what is at the ms-dos command shell, and we all know how well the anti-blaster worm worked with it's ICMP DOS. But given that a goofball scriptkiddie could connect like I did, maybe that is a good thing (good luck kiddies). Careful what you wish for and all that.

there's bound to be some kind of shakeout coming, right?
Not when the companies you get your (paid for) phone service from also provide the internet access that lets you run these VoIP programs that compete with them over their own networks.
It'll be a shakeout, but more along the lines of "them" lobbying for what you can and cannot do with your internet connection. And they will make it illegal for you to run peer to peer wireless networks in your own neighborhoods and cities, most likely citing a "threat to national security" because too much open communication that results in lost profits *MUST* be bad for good society in general. Well, at least in my coUSAntry.
Domain registration? That is no good... "It" compromises your web server, then installs a listener where it wants to bloom, it goes on and on. Wait until we get multi-headed viruses (the "lame" hydra concept from swordfish or the network of 13 viruses/worms from that W. Gibson X-Files episode.) It not only infects pcs, but has them connect back to backdoored webservers or pick-a-vulnerable-service to tell the third coordinator proc/worm which PC to infect next, that looks up a list of vulnerable backdoored PCs infected by sober and virus-of-the-week.

Wintermute Syntax Error: What are you doing, Dave?
It posts trollish looking messages and chats to you in IM.:)
Personally, I usually just chill while connected with ethereal running, then connect back to the PCs backdoored by the viruses that are trying to infect my honeypot on tcp/135. Then a simple netstat will show you an established tcp connection back to the IRC server the virus is using to announce itself to the author (not to mention about 500 connections SYN-SENT or ESTABLISHED to PCs being infected/probed, also a good source for other infected, backdoored PCs. You do know what is attacking you and what tcp backdoor it runs, right?) You can usually spot that connection, it has a high TCP destination port, whereas the normal vector port is 135/137/139. It's really sad to see thousands of PCs aleady announcing themselves to the author on that IRC channel as, "Hey come on over, I am running W2k|2XP. I am XP200453." And there is no one there to give me +OP privs!!! Batrastards!!! I could echo 'you are hacked please visit windowsupdate.com'> the startup folder all I want for days to each one of them to no avail... or echo ''you are a moron, too stupid to own a computer, put it back in the box and yadayadayada....
I wonder what I would do with a beowulf cluster of networks of hacked (i.e. unpatched windows) PCs. probably echo the same message in the same fashion as above, yet, alas, I am seriously lacking in motivation and spare time. (q.q.v 4. Pr0F1T!!!)
so little time, so many IP addresses, so many ignorant users.... so many clever, clever coders...
I really hate slipping those 5.25 floppies back into the sleeves when I go too far across the map. I mean, shoot, I have TWO FLOPPY DRIVES, and my desk is only so big, and I have to set the beer I sneaked up into my bedroom on my desk, so give me a break! It's bad enough I had to get a Mockingboard to hear good audio, and the 80-column card to get the hi-res graphics, what you want me to put an extra floppy controller in slot 5 to play your game?!?!?! SHEESH!!!
This is so silly! I can't wait until my disks hold 5 thousand times more and my PC is like a thousand times faster with more a thousand times more RAM!!!
(for those of you who don't get it, I am refering to good old Ultima games playing on my 1Mhz 6502 128k Apple IIe back in the 80s.... where have all the good programmers gone? Ok, not a thousand, but maybe 3.2 thousand times faster?)
Whatever, I am attributing your post to Zombie slashdot reader...
If I ever released a worm that put a P2P client on every zombie PC, and listened for 24 hours and got the top hundred list of common search terms on whatever P2P network, then downloaded it (to reshare), I could easily 1) infect with worm, 2) ???, 3) PROFIT!!!
The cat is out of the bag, P2P is here to stay, I don't care how deeply you inspect my packets. The internet and it's users will always be one step ahead of EVERYTHING. Adapt or die!
Yep, CPU went up to 100%, let it hang for a minute, click click, Firefox got the (Not Responding) in the title bar and I had to kill it. This was winXP sp2.
"hehehe I'll be safe, i'm using firefox! let's check this out..." Famous last words:)
Your network is a factor here as well. Do you know how much traffic you have on the network currently? Can your routers do prioritization on different traffic types, either IP Type of Service or tcp/udp port? You want to have that understood to make sure the quality is good, so VoIP doesn't affect your usual traffic and vice versa.
You can also get switches/modules nowadays that have Power over Ethernet (PoE). So of the two RJ-45 connections (you have the physical cabling for this, right?) in a cube, one connects their PC and the other connects the VoIP appliance/phone back to the PoE port. The phone gets it's power from the ethernet cable. If those switches and the rest of your key servers and network are on UPS, the phones still work when the power goes out.
I prefer garbage collection. At most, I take the cans to the edge of the driveway and some guy in a noisy truck with a cool robotic arm just hauls it away. Yeah, there is a landfill somewhere that isn't good for the overall environment but I accept that tradeoff. I also don't throw old car batteries into the trash.
Sure the hell beats me keeping the trash around, remembering where it is, and putting it in my truck and hauling it to the heaping landfill myself. I'm not here to manage trash, I'm here to get something done.
Yeah, so nobody actually read your question. Welcome to slashdot and sorry about that.
Sorry? It's just another desperate attempt to get slashdot to do someone's job. You linked to an 8 year old solution yourself. And besides, he lost me just after the fourth, "different." Then I saw he had two linux servers getting the mail first and I knew he'd be just fine;)

Screw the plugin of the month, I want this to work in Netscape 1.0 and NCSA Mosaic. That was also the very early days of JIT.
All this talk of performance does pique my curiosity again.

Just this last week I saw a brand new Dell server in which the hard drives had a plastic cover that made air flow impossible.
Don't remove that plastic cover. It keeps the drive's case from getting unsightly little scratches on it!
