Absolutely, we support PCs in warehouses full of wood chips, concrete dust and everything else you can think of, and the amount of crap they take before the PCs die is seriously impressive, especially on P2 and P3 machines which weren't so reliant on their fans to keep them running.
The shark is fairly out of date now, it was based on ssa technology which was much better than the scsi stuff out at the time, but fibre channel is much quicker.
of course, a large part of the shark is its massively parallel, 35MB/s per disk pack, but possibly 100s of disk packs per system, with 2 dedicated servers making it all transparent.
The replacement for the shark, the ds8000, can have 256GB of memory cache to buffer the disks and has a claimed 200MB/s throughput per port on a 4 port fibre channel adapter.
Spyware costs businesses serious money to support, it's simply so common that even the best managed networks of any size get infected constantly.

It is a bit of a pain, but if it's a decent hosting company it will be implementing SMTP with authentication for you to use, to send emails via them instead of whichever ISP you are connected to.
Pretty much every mainstream email client now supports it, and a any decent hosting company selling you service should support it too.
I've got a 3G phone from 3 and I did get video spammed on it a few times from the provider advertising things, after the 3rd time i phoned them up and complained, not received one since. I'll be leaving them in january when my contract finishes anyway, they're shockingly bad.

Reading the article, all I see is Sun saying how bad their old stuff was, e.g.:
Consider this case: To create a pool, to create three file systems, and then to grow the pool--5 logical steps--5 simple ZFS commands are required, as opposed to 28 steps with a traditional file system and volume manager.
and
Moreover, these commands are all constant-time and complete in just a few seconds. Traditional file systems and volumes often take hours to configure. In the case above, ZFS reduces the time required to complete the tasks from 40 minutes to under 10 seconds.
Compared to AIX or HP-UX, 28 steps is shockingly bad, both have had much simpler logical volume management for several versions now (AIX for 5 years or more? certainly as long as I have used it). The existing Solaris 9 logical volume infrastructure is years behind the competition, this is bringing it up to date, but not putting it far ahead.
You've really not thought this through yourself have you?
Which is harder - steal the shadow password file, generate an md5 collision using the method in this article which is still extremely taxing on the system involved, use the text that generated the md5 to break into the system who's shadow password you just managed to steal, or, just brute force the entry of the user-entered password?
Doing a dictionary attack where you know the result will be human readable is by far the easier way.
The couple of IP based KVMs I've used are just VNC based, nothing clever about them really. They come with a rebranded VNC client to make it look like their own stuff, but you can point tightvnc, realvnc, and the others at them.
More likely it's the compiler, I don't know what language the chess program is written in, but generally using the intel compilers for C or Fortran you can optimise the performance significantly . it might be in this case the gcc compiler wasn't fast enough.

While Half-life was great, any description of it as a "kick-ass story line" just shows how awful 99% of games' stories are.
Half-life story = guy starts new job at nuclear research site, guys first job is start up new experimental device, new experimental device opens gateway into other dimension, guy has to escape the research site avoiding enemies from other dimension and human anti-alien squads.
it has very good set pieces, and the scripting is way above the doom type we were so used to at the time, but the story itself is 100% action movie.
Certainly you've matched the price, but where's the reliability level?
The risk with a raid array is that a power surge of takes out 2 disks or the raid controller fails and corrupts the array, and in 1 moment you've just lost everything you ever backed up.
A tape drive simply cannot cause that same critical failure. Worst case, you replace the tape drive, and you carry on as before, probably with the loss of the tape currently in the drive.
if all you want is the ability to recover if your main raid array crashes, then a backup sata raid is fine, like you say it's big and relatively cheap, but it won't help if someone says they need a copy of the system from last month.

so basically "This is a message" produced the same hash as "This is another message "©{"
bluegene is based on that concept, 700mhz per cpu, 12 watts, i believe it achieves something like 6watts per gflop.
gzip uncompression is built into internet explorer, it's used all the time for speeding up the transfer of html to clients.
There's no reason why it couldn't be used for xml just as it is for html.

Yes, at £2billion a year profit, that's only, erm, £63 a second? My maths might be wrong though.
It's already starting to happen, major MMORPGs have been cancelled in the last few months because the publishers decided that they'd never get their money back with so much competition.
I guess the recourse would be the total destruction of the companies brand name when someone figured out not one of their products lived past 3 years.

As i said in my original post, put one tape a week in a bank vault. and how many 2 year olds do you see in a secure server room anyway?
