"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.
unless the drivers improved a LOT, most (all?) RAID IDE controllers are unsupported in linux. since the raid is really all done in software, developpers see no reason to code a raid for every drivers, instead they point you to the MD driver.
at the same time, the MD driver is faster than the cheapo drivers. or so they said last time i had one

there was a thread on nanog a few months back. something about freebsd kicking the shit out of every other OS out there for massive transfers like that, including linux. though if i recall it's really down to a matter of drivers:)
out of ~15 systems i've upgraded to sarge in the last two days, i've had major troubles with 3 of them, and expect the same on two more.
one of these 5 systems i tried to upgrade from apache to apache2 (non-critical system, so i could afford the downtime), another was a former production system that we pulled from the cluster to test the upgrade.
it would be a fallacy to expect a completly seamless upgrade for any system with major configurations that's been in use for more than a few years. what with the backports (because sometimes you just can't avoid em), packages installed from source (.tar.gz, not.debs), script s scattered all over (because you just know different admins like them in different places) and hardcoded paths.
despite all these caveats, it's still pretty easy to upgrade, so long as you know your systems. just don't do it outside a maintenance window:)
up here in civilized land they are required to recalibrate the radar every fews cars tested (or was it 1 hour?) and after every car caught for the moving radars. only by proving the officer was negligent in doing the various procedures (good luck) would you succeed in challenging a ticket
the default for the kernel is the anticipatory scheduler (IO). the help clearly warn you that for database apps, the deadline IO gives similar or better performances...
considering that OSX got completly destroyed in that benchmark, i say we give them a chance and stay with the AS:)
where's the pcmcia port on these babies? i could see this being used, along with a wireless card, to have an up-to-date calendar hanging on my fridge! mwahahaha!
i remember one teacher in college (math class mind you), he was positively the best teacher one could have. and he had a very particular way of giving homeworks.
after each class he'd give 10 or so numbers to do (doing these normally would take anywhere from 2 to 4 hours). now each "number" would have multiple problems. he was more than content if we did 2-3 of them if you understood what you did (or was it every other? it's been a while). homeworks were down to about 20-30 minutes, but you actually learned the stuff because it wasn't such a pain in the ass. no one likes repeating just for the sake of repeating. and of course, if you didn't understand what you were doing, you were encouraged to do all the tasks.
that's the intent. but from my own experiences it's hardly ever the case. of the last 3 servers i upgraded:
-one didn't upgrade PPP properly, leaving me with a machine without a net connection and unable to finish the upgrade (broken dependencies) -another didn't upgrade some modules at all, exim was broken, most perl modules weren't installed, mysql was broken, apache was broken, some libs were missing (gd), and the upgrade process installed the wrong version of php4 -the last one worked
i like debian, all of my servers uses it. but the upgrade process is hardly painless
just to say, up here in canada we were not allowed to leave the school premises either in elementary school.
a funny bit (or not so funny depending on how you look at it). my mom is the principal for one school, back a few years she told me some parents wanted the school yard to be locked and barbed so children couldn't leave at all (right now there's a fence, but the doors are open and you can leave with the proper authorization)
i'd be surprised if a power company DIDN'T have fiber. they already have the right-of-ways and the personnel to lay it. that's the two most expensive parts of the bill.
here in quebec (north, you know, canada) Hydro Quebec have a full fledged fiber network. There's also Hydro One (aka, Hydro Ontario) that actually resells full transit to the public in at least one data center that i know of. and let me tell you, for anything over 5mbit/s they're about half the price of everyone else (80$/mbit/s with a 10mbits commit)
it's even better when the boss don't know the others don't know shit about your systems... you get to laugh loudly in their face when they fire you, then charge them your consultant rate when they need help... ahh sweet sweet payback, can't wait

and you can get much worse. my laptop gets about 45 minutes if it's sitting idle, and tops 25 if im doing light work (say reading a book)

granted it's a p4 cpu, not pentium-M. but still

Reason will prevail, there's no doubt about it
you owe me a new keyboard, nice pun :)
it's all in your head..... or so everyone else tells me when i complain about it leaking :\

my guess is it's geographically tied.

yeah, now the new craze will be to export to canada. the lowend is around 15$/hr here. even as a sys/net/security admin that's what i make

nop you got it. though iirc it was nanobots they passed along
have you read neal stephenson's "diamond age"? he has one of those, they do computation by fucking wildly (and i mean that quite literally)

only a moron deploys a WOODY based debian desktop. someone with a clue will upgrade to testing or unstable

the main one is called charlie here (canada)
rsync uses rolling hashes for segments of the file. iirc segment boundaries are decided on by the client (i could be wrong on that part)
