It sounds like bad planning and testing to me. Why did they not do a trial run on small number of copies while still having the old system doing production? After the switch, why did they not have a plan to do a fast back-out if there were problems?
I help operate a Beowulf cluster of 16 Apple xServes, and I'm wondering if anyone has had any success in getting Debian or Gentoo onto them. One of our goals is to benchmark performance differences between platforms so we'd like to get our Apple, our two x86 clusters, and our planned Sun Fire cluster running the same OS. I've tried both Debian and Gentoo in the xServes, but neither of them will boot. Has anyone solved this problem?
The problem with caches is whether you can trust them. Even assuming you can keep the caches properly up-to-date, how do you prevent cache poisoning from taking place?
Maybe you should try out a *BSD? I've never had that problem with either FreeBSD or NetBSD. They're not just for servers; I've used both of them quite successfully as desktops as well. You can even run your Linux binaries through a full-speed emulation layer.
You know what you should of done when you first got your laptop, and you realized all the problems that you were experiencing. (If you have/had it convered under warranty) Just return the whole thing for a completely new one.
I tried that, and they wouldn't have it. They insisted that repairing the keyboard and fan were compliant with the terms of the warranty.
I don't mean to troll, but they really are. The only HP product I've ever bought was a Pavilion laptop, and it simply was one of the worst investements I've ever made.
The thing shipped with a faulty keyboard and CPU fan, making me ship the thing back to HP several times. Each time they "fixed" the problem (and reformatted my hard drive), but a few weeks later the problems resurfaced.
On top of that, the DVD/CD drive would only boot DOS-type CDs (i.e. Win98), not NT-type CDs like RH Linux and Win2k, so I had to boot into Win98 and use Loadlin to boot Linux or Win2k installers.
I would never recommend to anyone to buy HP products at this point. Caveat emptor.
If you're using a printer hooked up to a parallel port, do you have an interrupt enabled on that port? Also, make sure that you have a DMA channel setup for it. IIRC, you can pass these options in with the parport module.
I'm not sure what specific purpose you're aiming for, but Best Practical'sRT has been extremely useful for us. I'm part of a two-member sysadmin team that should be four, and RT really has been wonderful way to keep two overworked sysadmins organized.
So think of these changes as an incremental speed increase across the Intel platform. Sure, they're a heck of a lot more boring than seat-of-pants GHz updates, but I welcome decent integration of a whole new set of bus technologies (SATA and PCI Express) which we've heard a lot of, but not seen much action on. Remember that PCI has been around for 10 years or so now and is getting a little long in the tooth stuck at a 33MHz bus speed.
PCI comes in 66MHz and 100MHz varieties, and also at widths of 32-bit and 64-bit for all bus speeds. It has scaled extermely well.
PCI Express isn't as big a jump as it sounds like. The new Dell Poweredges have the ServerWorks GE bus architecture, which uses five separate PCI busses of various widths and speeds. This puts very few items on any given PCI bus, and PCI Express is just going to mandate one device on any given connection. I'm sure other manufacturers use similar technology.
This isn't just true with UNIX. Any OS that actually supports a distinction between user and administrator will have that. VMS, ITS, OS/390, MVS, OS/400, zOS, zVM, and a host of others all have that same functionality.
Come to think of it, it really is just Microsoft and some old Apple products that have this problem.
Kind of. It might not mean much on a workstation that only one user uses, but imagine if you running a server with thousands of users. And if you're really concerned, taking frequent backups isn't such a bad idea, even without the concern of virii.
Looking at the EU's premises, it looks like blame could just as easily be placed with the machines that deal with money and not with software. Why not require that counterfeit detection be built into vending machines, ATMs, etc.?
I can type my password, but if you asked for it I couldn't tell you what it is. The other day someone needed my password for one of the test boxes. I had to open vi, type in the password, and read it back to them.
I'm the same way. When I dislocated my shoulder, I had a hard time typing my passwords in the original sling, because I was basically limited to one hand, and I only knew the passwords with two hands. With some creative torso-twisting, I managed to get both hands on the keyboard at the same time. Fortunately, I regained mobility pretty fast.
I once recovered a senior's project from a random corruption in M$ Word. The text was still there, but Word wanted nothing to do with it for some reason.
I managed to get my Linux box to mount it, and copied the document off the floppy. Using strings, I extracted the 40 pages of text sans the formatting from the document. She wanted to pay me, but I talked her into dinner instead. Being a college student, having other people cook decent food rather than cafeteria food was worth more than money.
No wheels?

NASA has learned that exercise can counteract some of the effects of low-gravity on astronauts.
I don't understand this rationale not give any of the mice wheels. The first humans on Mars are unlikely to be sitting in front of a TV drinking beer all day; they'll be experiencing a significant amount of exercise maintaining the habitat, exploring, and conducting research. Give at least a few of them wheels.
One problem, however: It's just the front page. The meat of the information is still hiding on his server.
It was originally just the front page. I decided to get that up fast to get the load off the original server. I've just updated the mirror with the important links, but those took a little longer to fetch.

Personally, I'm a fan of rcs.mgr. It uses a Perl script frontend to manage an RCS baackend, with all sorts of logging, roll-back, and other options.
