One correction: the computer sees it as as many SCSI disks as you feel like configuring if the IDE RAID unit is any good; this is certainly the case with Promise equipment).
Thus you could use an RM8000 to provide, say, a 2 disc mirror for a boot volume and a 6 disc RAID 5 for data.
The RM8000 from Promise is excellent for read performance, and a joy to manage. It's cheap, and has an Ultra160 interface, and can be managed either from the LCD menu on the front panel, or from a serial port on the back.
There is one caveat, though: I build one to use for a predominantly archive server (so used RAID 5). While Bonnie and solaris iostat confirm excellent read perfmance, with throughput limited by the host's ability to process data, the write performance is lousy (Bonnie shows 100MB/s+ for reads with the V120 pegged at 100% CPU; but write is only 10-20 MB/s).
This is a little like the argument that says "use a dedicated coprocessor for SSL!"
Over the past few years, the counter to that is: buy a multi-CPU system. The price delta between a dual MB/2nd CPU is a lot less than most dedicated SSL boards, and when the second CPU isn't doing SSL, you can use it for other stuff.
The same is true of RAID controllers: the embedded controller in a RAID card is much less powerful than a second CPU used for software RAID. You may be better off spending the cost difference on another CPU. Especially when you consider that if a RAID controller dies (and this *does* happen), you're SOL unless you have a spare handy. With software RAID, boot the disks on a different system, you're back in action.
What RAID cards can offer is stuff like NVRAM to cache for page outages.

In 1988 SCSI was still bloody cheap compared to, say DASD.
It's kind of ironic. I imagine you're probably misusing "moot" to mean "not worth discussing", but the fact you missed the point means you're actually using it correctly.
The fact Alpha systems aren't compatible with Itanium ought to matter to HPaQ customers because all future HP-UX and VMS systems will be Itanium based. Whereas customers buying US III machines know that there will be future generations of the UltraSparc acrhitecture and that will be their (seamless) upgrade path for the forseable future.
Desktop video is one that springs to mind - lotsa memory.
I can buy PC133 @ US$60 per half gig. For US$500, I can fill the address space of the 32 bit processor, yet a non-trivial home movie could occupy more than 4 GB in uncompressed form.
The Rosetta stone's role is actually urban myth, but yes; deciphering Egyptian was bascially a life work for a number of people, only one of whom succeeded. Moreover, had Napoleon not invaded Egypt it may never have happened - only a generation later, many of the great Egyptian monuments had been destroyed by Egyptians themselves, rendered down in limeworks or pulled down nd used to construct new buildings.
It's not English, it's Latin. And the writing style is not what we would consider a modern Latin alphabet, which wouldn't help you.
My wife could read it when we visited, but that's because she's spent 7 or so years studying (amongst other things) Latin, sundry other dead languages (Old English, Old Norse, Gothic, etc) and the scripts of the time. Most of the other people in the queue just looked hurt and confused by the small, rather unimpressive looking book that was illegible.
The book has lasted 1000 years, but it isn't that accessible - you certainly can't just grab at it, because it'll disintegrate. And the writing style is illegible to anyone beyond a relatively small number of specialists, even though the language is, IIRC, Latin. Not that there are too many Latin speakers these days.
The headline and article *seriously* underestimate the problem of dealing with old texts (try reading Beowulf; sure, the language is called English, but you'll spend a few years mastering it!), or how many have been lost. In World War I, for example, one third of the then extand medieval manuscripts that had survived when the German army burnt a Belgian University to the ground to punish the Belgians for resisting the German invastion.
The virtue of digital technologies is they're easy to replicate; the problem with this is that you actually need to replicate to newer and newer technologies as time goes by, not unlike dark age monks eternally copying out works to preserve them.
Yeah, that's right. The current generation *always* knows what's valuable and what isn't.
For example, we don't miss any of the treasures of the Roman empire lost under Constantine, Justinian and his successors when the newly ascendant Christians went on a Taliban style orgy of destruction, smashing up anything they considered "pagan" or "unacceptable".
And scholars of Rome *certainly* don't miss any of the works held in the libraries of Rome that were destroyed by the Gothic invaders before the so-called dark ages.
Nor does anyone regret that poverty striken Icelanders took to using ancient manuscripts for dress patterns and firelighters in the 19th century. Nope, didn't lose much there at all.
Hell, we don't even miss all those Egyptian writings destoryed in the 19th century. Or by the Aswan Dam project.
And of course, accidents never happen. Just forget about that little fire in the Library of Alexandra.
I genuflect to your superior wisdom and knowledge.
I think you'll find Ferrari are owned by Fiat, which is (for now) an Italian company.
And for a goodly chunk of their history, Ferraris have been notorious for their high maintenance requirements when compared to other high performance cars, anyway.
I've posted a pointer to the actual regulations further up in the discussion. They have not banned animal protiens in livestock feed, there are plenty of loopholes in the definition - most notably any animal protien which has been prepared for human consumption. Since cooking a meat-on-the-bone meal doesn't kill prion-based illness, you've got a huge infection vector right there.
Perhaps you ought to take a look at what the rules are on animal feed in the United States. Amongst other things, a cow can be fed food scraps of animal protein - yet cooking does not destory prions, as many people in Europe can tell you.
Note that deer populations were never a problem before hunters with guns showed up.
That's an overly broad claim. However, there is likely a correlation between "humans with guns" appearing and "exermination of wolves, mountain lions, bobcats, and other deer predators".
This is a pretty regular thing for the area. The press gets wind of some sort of memo and the whole thing gets blown out of proportion. Things that should really only be semi-major events (like the Wen-Ho Lee case, for example) get turned into media circuses.
Wen-Ho Lee sould have been a major case, but the press got hold of the wrong bit: why were US federal agents able to abuse their powers to try and "get" someone long after it became obvious the agents had cocked up? Why are they being offerred more powers?
most, not all. what if the website you're visiting only has pop-ups for ads? in that case, the pop-up ads would be the only source of revenue for them and by blocking those ads, you would be in effect stealing the right to view the content on the site.
Stealing, my arse. I haven't stolen anything. Nor have I breached any contract. Claiming that visiting a site while refusing to view some elements represents theft is the same as some bozo trying to claim that breathing is stealing "her" air.

Funny.
All the guys I look up to don't waste time with that SCSI crap. FC-AL all the way.
WTF is it with people thinking RAID 0 is a good idea? You have my sympathy, but who/what made you think it was a good idea?

Hey, let a guy have a little hyperbole...
The New Zealand market isn't quite as price competitive as the US one, unfortunately.

Yeah, that huge chunk in the appendicies isn't part of the book.
Hey, let's ditch Elvish, it's only in the appendicies!
Dork.

So stone isn't that future proof either.

Chiselling in stone. It allowed Egyptian to survive long after the language and culture had dissapeared.
Even then, huge chunks were lost to the destruction of monuments and suchlike.

Release wolves into the wild again, then. That'll take care of the deer.
