You have one of those too, huh?
Mine lost her VISA not once but TWICE during a one-week trip to the Dominican Republic. Once in the ocean, the other time she threw in the garbage with an empty pack of smokes.
My dad used to work in a classified (but not top secret) environment, and couldn't figure out why hard disks were failing at an alarming rate.
The security procedure was that end of the day, disks were removed from PCs and placed in a locked filing cabinet, in case the building was broken into and the PCs stolen (this was early nineties -- PCs still expensive enough to be worth stealing by amateurs).
Well, he had to work late one day, and hears the secretaries packing up. Clunk, clunk, clunk, slam!
Yup. They were taking the harddrives out the PCs and *tossing* 'em in the filing cabinet.
Accidental file deletion can be mitigated by checking everything you value into CVS. Ever tried to remove a file from CVS?
RAID controller is irrelevant. Software RAID is the way to go.
RAID 5 also sucks. RAID 10 is the way to go.
There is still no replacement for off-site backup, though. Which is why I thinking of running an FC_AL loop a few klicks away and RAIDing with it. What the hell do you call a three-way RAID, anyhow?
I recently had a couple of REALLY nasty RAID failures due to a... datacentre malfunction.
One raid lost 9 out of 20 disks at once, and the disks were irreplaceable (no longer made). I thanked my lucky stars that I still had half the data, blew away the [software] RAID 10, re-setup as a stripe (RAID 0), fsck'd, and mounted the filesystem. WHEW! Then I still had torestore a severely crashed Oracle with no Archive logs (didn't have any hardware to control THOSE disks. Damned hardware RAID!), but that's another story for another day. No data lost.
Another RAID lost eight disks out of 36. Six almost all at once, and two more during the repair(!!). Again, no data lost; this time due to automatic hot-sparing and again, RAID 10.
Both scenarios could have been recovered by other means (offsite backups) but it's amazing how much damage a software RAID10 solution can withstand and still let you have your data back.
Oh, and of course, half of your RAID should be connected to separately power supplies if you're serious about your data.
For a home solution, all you need is an internal disk and an external SCSI disk. Chances of you losing anything to hardware failure is VERY low.

> Perfect stupidity, sure it's better to blame someone
I disagree. The reason is subtle, yet perfectly clear [to me]. I firmly believe there is no such thing as a project which goes off without a hitch. Hence, when management insist that such a project occurs (despite objections from realists!), the very first thing which should be at the top of your list to do is to hire a scapegoat. If you can hire one who knows WTF he's doing and can really contribute, well, all the better.
First off, if this is a "must succeed with no problems" project, all bets are off -- hire an experienced consultant so you have someone to blame. Also, this technique only works when you have the type of site which will *build up* to expected load -- not get turned on instantly.
This is tough to generalize without knowing specifics, but here goes:
1. Make sure your application can work correctly when load balanced across multiple boxes 2. Keep webserving and DB work on different machines 3. Make sure your application can work with another database without much work (this gives you the option to hire, say, an Oracle DBA and buy an Oracle license if MySQL can't keep up.. does it even support row-locking yet?) 4. Have extra hardware handy, in the rack. Do NOT turn it on yet. 5. Observe the application running; determine bottlenecks, tune 6. If you can't tune it to perform adequately, NOW is the time to break out the extra hardware while re-evaluating the implementation.
If you throw all your hardware at the problem at once, you get very little warning when the shit starts to hit the fan, and no response scenario. Do NOT make that mistake. Load, test, tune, repair, repeat.
I saw inside one of those.. Geez, had to be 12 or 13 years ago.
What I remember was that the front of the case came off, exposing a bunch of HUGE cards mounted vertically. They were like 12x10" or something crazy like that.
I remember one of the cards had a processor on it, so they must have all plugged into a passive backplane.
I remember two cards had a SHITPILE of ram on them. 30 pin SIMMs, I think, on one; the other was VRAM IIRC, on the display postscript card. The DPS card might have had an Intel i860 or something like that one board as well.
I don't remember where the optical and hard drives were. Below the cards, I think.
If you took a Sun Enterprise E3K, flipped it around, chopped off the drive bays and put a single cover over all the boards, you'd have something resembling a NeXT Cube, only purple.

Actually, he didn't say the cube was invented thirty years ago, he said it's been *around* for about 20 years. Assuming he lives some place in North America, that's definately true. I remember they first started appearing *around* me in 1982 or so. Before that, they were unheard of (and I don't remember seeing any in Western Europe in the 70s, either).

That fact that he kept his promise in this matter shouldn't be newsworthy; I'm surprised they even bothered keeping the polls open last night.
Tannenbaum is reporting that the exit polls and the actual vote results are quite different there, as well. Big surprise. Of course, there is no proof that the fix was in, because Diebold machines don't leave a paper trail.
> but is there a huge gap in functionality between the GIMP and Adobe's PhotoShop?
Yes. It's nearly as big as the gap between Wordpad and Word under Windows.
> Would Adobe be able to take market share away from the GIMP, > which is bundled with a lot of distributions?
No. It's a completely different market. The market for Photoshop under Linux would almost certainly be very close to a proper subset of the union of the markets for Photoshop under Mac OS and Windows.
There also isn't a whole lot of competition for Photoshop in the Pro arena -- anybody who suggests using Paintshop or the GIMP as a replacement probably doesn't need Photoshop for whatever they're doing, and more important, probably wouldn't pay for Photoshop anyhow.
The only good business case for Photoshop under Linux would be fear from Adobe that Microsoft is going to f! them up the ass at some point in the future. Professionals using Photoshop don't look for software that will work with their OS/Computer -- they buy their OS/Computer to allow them to run Photoshop.
Due to the openness of Linux, Adobe also has a chance to make Photoshop run a little better, however -- but this would be very expensive due to the lack of libraries, GPL entanglement (i.e. -- could they use GTK? Could they improve it without opening Photoshop?), and uncertainty/infighting with Xfree86.
If Adobe chooses to go for Linux, though, they won't bother with any infrastructure changes. They will either adopt a GNUstep or a Mosaic platform as their "standard", build whatever they need on top of that, and come out with a product which is about as good as their product under Windows.
Unless, of course, Adobe has some lofty goal of producing single-purpose imaging workstations. But that makes no sense to me from a business perspective.
No, because you wouldn't be able to resolve/dev/zero to its device numbers (it's gone, remember).
> Or will my gpm work without access to/dev/mouse ?.
I'd expect it would probably work as long as you started GPM before you wiped the filesystem. Remember, files aren't gone until all hardlinks are removed AND the descriptor table is empty.
