Each of them run as the current logged in user. Therefore, it can only search things that the current user has access to. The database that everything is stored into (the index) is user specific as well, stored in:
%systemdrive%\Documents and Settings\[username]\Local Settings\Application Data\Google\Google Desktop Search\
Other non-admin users do not have access to your index. Obviously, admin users will have access to all non-encrypted files on the machine, and the google desktop search doesn't change that.
Ah yes, obviously those ports are happening fairly quickly thanks to the HAL. The tricky part is either recompiling all the applications, or providing an emulation layer for backwards compatibility (or both).
Ever heard of the H.A.L.? Not the computer from the movie "2001", but the Hardware Abstraction Layer. It's what let NT run on x86, PPC, and MIPS. The HAL is still there in XP and W2K3, but they only have the x86 version available these days. If there was an economic reason to bring Windows to PPC, it would be fairly trivial to do so...
Yes, good points about available storage vs. raw storage. They usually market these things based on raw storage, since the user can decide if they want redundancy, and how much.
However, I think you're confusing NAS (Network Attached Storage) with SAN (Storage Area Network). Nothing gets shared to users directly from these boxes. In fact, the SAN doesn't have to be connected to an IP network at all (although most can be for management purposes only). The fibre channel (not necessarily fibre optic, it works on copper as well) connection acts like SCSI. It actually uses the SCSI command set if I recall correctly.
The storage acts as if it's local to each server that attaches, and then the server shares it out however it likes. It can be used for file shares, database storage, mailboxes, whatever.
For example, if you assign 1TB to a windows server, and connect that server to the SAN, you'll get a virtual disk device in your device manager, and disk manager will show an available disk for partitioning. You can then format the new partition, say as the D: drive, and format it with NTFS. Similarly, if you connect a linux server to it, you can partition and format with ext2 or whatever other filesystem you fancy.
The SAN itself doesn't care what filesystem is placed on it, it only cares which servers get space assigned to them, and how much.
"I just spec'd out a 3u high enclosure that has 12 drive bays, 4GB memory, dual AMD 64 processor, dual processor motherboard, 2 mirrored system disks, raid controller, populated with 6 x 250GB drives. All this for around $5k. I like populating with half the drives so I can easily pop in the next gen drives. Oh and don't forget Linux. And don't forget, its 64 bits. yeah!
I think the price for an ideal configuration is 16GB, 12x400GB for $12k."
Great, you just spec'd out a pretty nice server. Contgratulations.
That has absolutely nothing to do with this conversation though. This IBM system is not a server. It is for providing gobs of local storage to MANY servers. It's highly available storage, period.
What you could do is take all the storage out of the box you just specced, other than the system disks, and just pop in a fibre channel card (or two for redundancy). This IBM system now provides your data storage volumes, as well as volumes for the tens or hundreds of other servers on your SAN.
If one server is running out of space, assign it a little more from the free pool. If another server is not using all of it's space, take some back.
When you have all your storage in one place, it makes your whole server farm much easier to manage. All your backups are centralized. If you have 10 servers that need a pile more storage, you only have to upgrade this one unit, instead of visiting all 10 machines. Since it's designed to scale, that upgrade is very easy.
Each 3U unit actually holds up to 16 300GB fibre channel disks. That 4.8TB per unit. You can then chain up to 14 units together (one base unit and 13 expansion units) for a total of 67.2TB.
That's raw capacity, not accounting for redundancy.
"IBM is using the less PowerPC chip, which means it will be tough to run standard software distributions on it rather than IBM's more proprietary offerings, but you may not care about that on a fileserver."
These are not servers, and will not run any "software distributions". They are simply storage boxes, and they connect to your servers via fibre channel. They can connect to "IBM z/OS®, IBM OS/400®, IBM AIX®, as well as Linux(TM), UNIX®, Microsoft® Windows®, HP-UX and SUN Solaris environments."
Wasn't it eventually proven that the problem with those Audis was simply an unusual pedal placement? Since there was a larger than normal transmission hump, the pedals were all shifted to the left, putting the throttle pedal where some people expected to find the brake.
The common reaction among panicky types when the car suddenly started accelerating was to just push harder on the pedal, instead of calmly trying to figure out what they were doing wrong.
Car and Driver did a big article on this a few years back.
"This is exactly what gasoline-electric hybrids like the Civic Hybrid and the Prius rely on when they shut off their engines."
Actually, no. The Prius and Civic Hybrid both use electric assist for their power steering and braking systems.
The steering is a simple electric motor that assists with steering force, and the brakes have an electric vacuum pump to maintain vacuum in the system.
The Prius actually uses a "brake-by-wire" system (with hydraulic backup), so the computer controls the braking pressure that gets applied. It does this because the regenerative braking system causes the brakes to be twitchy, so the computer has to make adjustments to smooth it out.
"I had an exciting moment on a bike when I overtook someone and the throttle stuck wide open. Not so easy to kick into neutral with a sequential gearbox, so had to reach down to the key and switch off. Fun in city traffic..."
She should get to a doctor right quick. I did the math on Top Thrill Dragster after I rode it. It does 0-120mph in 4 seconds, and that works out to approximately 1.3g acceleration. 0-70 in the same time period is probably below 1g. If that caused her to black out, she's got problems.
"If it is like the Top Thrill, I think it is kind of a waste of time. Even for its intensity, I expect a few minutes worth of a ride for waiting a freaking hour in the blazing sun, not to mention the hours it takes just to get to the park."
I don't know. I drove for 6 hours from Toronto to Sandusky on the second weekend of Top Thrill's existance. We waited in line for 5 hours, for a ride that lasted 26 seconds (I timed it). They were still working some bugs out, and it shut down several times, but we persevered.
I still think it was worth it. What a rush! Millennium Force is also an incredible ride. Totally worth the trip.

To answer my own question, there's the HP ProLiant DL585. 4 Opteron processors, four hot swap drive bays, up to 64GB ram. Uses the AMD 8000 series chipset. All in a 4U rack mount chassis. Very nice.
I guess AMD really is getting ready to take over the world:).
By the way, I'm no AMD hater. My box at home has an AthlonXP 1700+ in it. I just wasn't aware there was anything available in the "Large x86 Server" catagory.
Is there an equivalent to the ServerWorks chipsets in the AMD world? Are there any motherboards out there that can handle 4 or more AMD processors? How about pre-built multiprocessor servers with hot swap raid subsystems using AMD?
Seriously, if these are available, I will look into them. I just haven't heard of anything on this scale with AMD processors.
The closest I can find is the IBM eServer 325/326, but they're only dual opteron pizza box machines. I can't find any bigger AMD servers out there.
Excellent point. There's a huge difference between driving fast, and driving like an asshole. There's also a big difference between driving fast and driving dangerously.
I drive pretty fast most of the time, but only when it's safe to do so, and I keep a keen eye out for cops. Because of that, in 13 years of driving, I have not had a single speeding ticket or accident. Not one. I also use my turn signals religiously, and I always vacate the left lane as soon as I'm done passing someone.
My brother's mother-in-law on the other hand, always drives the speed limit. She's had SEVERAL at-fault accidents that I can recall. She also sits in the left lane and wonders why so many people are flashing their lights and honking at her. We've tried to explain why, but she doesn't believe us. Sheesh.
I've known other people who drive fast regardless of conditions or traffic. They all get speeding tickets all the time. One guy I know had 30 minor speeding tickets in one summer. Two of them on the same trip home from work! I have no idea how he managed to keep his license.
Anyway, I made my point in the second sentence of this post, so I'll stop now.
"I've used both and I have to say that Microsoft's Virtual PC is ASS-slow. VMWare is actually usable and has far more features and compatibility."
Actually, once you set the priority on VPC properly it's pretty close to the same performance as VMWare. The most important differences are as follows:
1. Memory support goes to VPC. VPC supports 4GB of RAM in the host machine that can all be assigned to virtual machines (but you have to keep enough free for the host machine to run, of course). VMWare can only assign a total of 1GB of RAM to all running virtual machines, regardless how much actual RAM you have.
2. Snapshot support goes to VMWare. In VMWare, you can take a snapshot at any time, even when the virtual machine is running, and restore to that exact state within a few seconds. VPC requires you to shut down the virtual machine before you can take a snapshot.
Other than those two items, they're pretty much equal (there are minor differences in how the virtual networking works as well, but that's not as important in my opinion). They have quite different interfaces, but pretty much all the features are there in both. You just have to decide which of those two items is more important to you. For me, number two is a bigger deal, so I use VMWare.
"When did they change the rules? It used to be that you could be on 5 times... max, at which point you retired as an "undefeated 5 time champion"."
It was very recently. I think within the past year. They made a big deal out of it when they changed the rules. Now the champion keeps playing until they lose.
"If you read the blurb, he turned off all firewalls as per instructions from MS. Thanks for playing."
I'm interested to know who at microsoft gave him those instructions. They're not on the windows update website, or at least I can't find anything saying that. There is no reason to disable any firewalls, hardware or software, before installing the required patches.
Anyway, what I do is keep all the pre-SP2 critical patches on a USB key drive, and install them all before connecting the network cable. My XP CD has SP1 slipstreamed, and the patches all fit in a 22MB zip file.

Well yes, but you missed my point. These people THOUGHT they were standing on the brake, but were actually standing on the gas. Totally driver error.
