hmm here in the uk every isp i have used has given me a real ip and i'd be pretty pissed off if they didn't.
large scale nat has advantages but it also has big disadvantages (like requiring a connection tracking system in place to actually do the nat). and like pissing off customers who have a clue (and its customers with a clue who tend to get asked by friends what broadband provider to use).
i doubt that with broadband you would use hugely more ips with a sticky policy (ie only change ips when you change the network design but still use dhcp to let you make those changes) rather than a fully dynamic policy. and it makes it a lot easier to keep track of who is doing what and for services to ban troublesome users.
no the grandparent has it right for a 2 way satalite setup (ie where the satalite is your only link to the isp) ping time is a measure of how long it takes for a packet to get from you to a remote server AND back again.
its 120ms from you to the satalite 120ms from the satalite to your isp whatever time it takes to get to the destination server and back 120ms from your isp to the satalite 120ms from the satalite back to you
so the MINIMUM ping time you can have to anywhere on a two way geostationary satalite hookup is 480ms
one way to reduce this is to use a modem for upstream and the satalite purely for downstream. This however means you need a phone line and have very little upstream bandwidth.
you are right nowhere near as bad as letting it back up through the sewer systems into populated areas but that doesn't mean its a good thing just less bad than the availible alternatives.
those sewage treatment plants were installed for a reason you know.
for packets to end up in another part of the world before being finally rejected.
many systems are set up to use an upstream transit link if no local routes can be found so packets can get sent quite a long way before they finally hit a brick wall.
no talk page on that wikipedia article which tells me its not to be too highly trusted
i'm sure that what i heared was that S/PDIF was the original coaxial based system and that TOSLINK was a fibre cabling system based on it that worked using the same protocol.
surely if your fixing pcs it would be prudent to have some kind of safe net with minimal access to or from everything else that you can hook pcs up to to download patches get data off etc.
just a second nic in a linux box with nat enabled and tough firewall settings would do the job it doesn't have to be anything fancy.
thing is with the 9x and NT lines there were good reasons to use the NT line over the 9x line which justified the price difference.
when the lines merged they had to deliberately cripple xp home to make people buy pro and the main way they did this was by crippling network security to the point that it was WORSE than 9x.
do you view the browser and web as something that should be standards based to the end or do you belive its ok to build a web site for one client app just as you might build a client app locked to one gui toolkit?
or to put it another way do you wan't to build a website or an app that happens to use firefox as a client.
many laptops set a hard disk password when you set a bios password
getting round that is not trivial. Probablly possible but probablly a job where a speciailist data recovery firm would be needed. (you either need custom firmware OR you need to wipe the protection info off the platters AND replace the controller board iirc)
skype has got it right but only by playing really dirty
they take the bandwidth of lusers who have unfirewalled network connections (or who have firewalls but are ignorant enough to open the ports) and use it to route calls of those who are behind even the most restricive firewalls and to keep the networks structure together
basically skype relies on exploiting idiots to allow everyone to have service even if behind a very restrictive firewall.

aren't datacenters supposed to have backup power?!
or is there more to this story than we are being told right now?

cherry still make high quality basic keyboards at fairly reasonable prices.

note: it seems that in the uk cherry sell british layout keyboards but the pictures on the box show a german keyboard!
yes exactly its a method of last resort

so that when legitimate users misplace the original box/sleeve they get hit for another copy of the product
nah its an adaptation of a popular troll
maybe it is true and/or convincing the first time but the almost identical wording to previous times gives it away.
yeah its still labeled "alt gr" on uk keyboards and it is a seperate scancode
if modern us keyboards don't have it labeled like that then it seems like a simple case of dumbing down
hey is this a deliberate parody of the troll?
check thier terms and conditions and if you belive a seller is in violation report them!
its the only way you have any chance of getting anythign done against such people.

good f*cking luck slashdotting wikipedia
/. nowadays and that /. is like the ideal flash crowd right?
you do realise don't you that they handle considerablly MORE visitors than
mmm nice variant of the troll but its still easilly recognisable.
your trolling from an account with karma bonus too wow!

that checkbox only exists on xp pro.

iirc wiring one end to TIA-568A and the other end to TIA-568B gives you a crossover cable
so if your switches are half decent it shouldn't make any difference the switches will just detect it and connect fine.
it depends
do you view the browser and web as something that should be standards based to the end or do you belive its ok to build a web site for one client app just as you might build a client app locked to one gui toolkit?

didn't appollo use pure oxygen to save on weight?
i'm posting this reply without karma bonus as i suspect this is a troll.
i highly doubt the rovers could do the kind of speeds needed to make that significant.
and ofc if you do speed along then you generally end up in an even worse state when you realise something has gone wrong!

ok i haven't used access in a while. What you mention is certainly not the case with access 2000.

trouble is large scale production is efficiant so they can drive competitors into the red without having to go into the red themselves
then when the competitors are dead just put the prices back up
