The problem is that the encoding is done on three-vector bi-furate substrate instead of the two-vector bi-furate substrate used in the Raptors, and the 3V stuff can't handle speeds of the 10k RPM (the lateral acceleration at 10k RPM is significantly more than at 7,200 RPM, and the 3V stuff is taller than the 2V stuff - hence the problem.)
Contact the professor that is teaching the Boston University MET* CS_579 class L2 Database Management.

The class was one of the more difficult classes I have taken, but I came out of there on par with most of our DBAs (and more fluent in Oracle 10g than a few of them.)

Bingo - where I work all the regular worker bees get locked down machines (can't even change the desktop wallpaper), and the developers get unlocked devices after they sign a paper that says if they abuse it they are true and royally fucked (or at the very least, fired and then escorted out the front door by uniformed police, your personal belongings will be sent by HR to your last recorded place of residence.)
I can do anything I want on that machine, and I don't even surf/. on it - it is a work box. They trust me to use it for work only and I honor that trust. I have plenty of play machines at home, and I respect my employer (because he respects me.) Oh yea, and they pay me low six figures and I really like that, and I know there are a thousand of you guys lined up to take my spot if I cop an attitude about my work laptop.
I think the key difference between Pro and Home is that Home won't let you join an Active Directory domain; XP will. Not a big thing, unless your company uses AD (which most do.)
I'm a developer and ex sys admim without a Slashdot user id. Shit, I wouldn't trust you either. Maybe I should start asking applicants what their/.uid is so I can see who they REALLY are, forget this silly resume fluff crap.
Actually I have (it's in my journal too) - but as wonderful as VMware is (I love it,) there is no substitute for cubic inches. If you have 400 CDs to rip to MP3s in one night, VMware doesn't add physical CD-ROM drives to your machine.
Yea, well...monitors are nice, and so are women - but beyond two or them (or one really nice one) and most of us don't know what to do with all of them.
Want to get some serious hacking done, get a nice RAIC going. Anybody that has been following my journal for any length of time knows about the RAIC - redundant array of inexpensive computers. Get four nicely configured (2.8GHz Hyperthreaded CPUs, 2G RAM, decent hard drives, GigE switch tying them all together) coming through a four port KVM to one nice 20" LCD (or better.) One of the four machines with a monster hard drive array as the file server, the rest with various development environments.
Got a compile happening that takes half an hour? Let it run and hotkey to another machine. Doing client server or web development and you want to test it with Linux and Windows clients? Multiple machines make that happen. Four thousand lost clusters after an improper shutdown? No problem since you back your stuff up to the file-server over GigE on a regular basis. Debugging a full screen application and want to Google for some insight? Hot-key over and use the browser from another machine. Need to spend 20 minutes doing virus scan or MS patching or rebooting because today is Wednesday? Now that can be productive time since you can hotkey over to another box and get back to work. Want to experiment with Oracle 10g but you are concerned that it will cause problems with your development environment? No worries, one of the four machines is Ghosted so you can throw all sorts of crap on it, play with it and blow it away a few days later without worrying about your 'real' dev environment.
Multiple monitors is cool, yea - but the freedom you get by having multiple machines is quite a bit more powerful.
Actually there's more to that than most people realize - seems the shower fills the room with ions (negative ions) which have a significant effect on one's ability to focus and have the sort of introspective thought that is highly conductive to problem solving. Add in a relaxing environment devoid of other detractors and you get a pretty good 'think tank'.
Maybe they should have posted an 'Ask Slashdot...' before they did anything.
Dear Slashdot, We are thinging about using an Oracle database, Windows operating system, Unix hardware and an Apache webserver for our new administrative package.
What are your recommendations, based on your professional backgrounds and experience?
1. You're in a desert, walking along in the sand when all of a sudden you look down and see a tortoise. It's crawling toward you. You reach down and flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over. But it can't. Not without your help. But you're not helping.
Why is that?
2. Describe in single words, only the good things that come into your mind - about your mother.
Why not send big wooden sailing ships over there, load it full of the darkies and bring them back all chained together, auction them off as free labor?
The US Government did that for the tobacco and cotton industry back in the 1600's and both of those industries are simply BOOMING, even today four hundred years later.
Damn, that would be sweet. Hold tight Kunta Kintegopapura - we are coming!
Actually I thought about that - if infrastructure let everybody double the number of machines they had on the network without adding staffers, in theory the IT cost per box would be half and we would have twice the horsepower.
I was gonna say... yea, everytime we start dreaming happily about the C=64 we all had and loved, there is always one sorry motherfucker that was abused as a child (his parents got him the 8-bit Atari) has to come out with childhood fiction stories like 'Alice in Wonderland', 'Three Bears', and 'how much better the Atari 8-bit machine was than the Commodore 64.'
Maybe it really was said by a CEO in 1989, when rave culture was still underground, and he was being SERIOUS (but it is funny now because... well because it is funny (trust me, it's funny.))
You forgot the most expensive (and often overlooked) part of infrastructure : the infrastructure staff.
Add a few $65,000 / year staffers in there to install / support those $2,500 machines and you are looking at $13,500 per year (every year) per machine. I know, that's what my company bills my department for each server I have on the network.
If you have a problem that takes 400 CPU hours to run, your answer is either inanely worthless, or mind-bendingly valuable (I needed to throw one of those in there for the SETI group, but I won't say which.) Well that or you need to optimize your code, or get a faster machine.
That said, it probably isn't worthwhile to the guy with a $400 problem - more likely they are looking to appeal to the kinds of guys that want to crack 128-bit encrypted data streams in real-time, or run two neural networks against each other in a zillion games of chess in order to teach (evolve) their neural network, or crunch two terabytes of data picked up by an Indy race team over three days at the track. Brute forcing 1024-bit encryption is totally possible, but the data isn't generally valuable a thousand years after you start decrypting it. Throw enough horsepower to decrypt 1024-bit RSA in real-time and you will find yourself rich (or dead.)
Knowing the winning numbers to the lottery thirty minutes after they are announced is pretty worthless. Knowing the winning numbers to the lottery thirty minutes before they are picked is worth a hundred million dollars. Amazing difference having the answers an hour earlier makes - I'm not saying that these computers will give you that much of an advantage, but I'm still saying... I currently work on problems where an hour difference in processing time can make a single data-crunching run cost about an additional $100,000.
shit that the programmers didn't imagine could happen, and I saw a few of those things
Just finished a class that went through all the advanced stuff Oracle can do (most databases, come to think of it,) including pre/post triggers. If you want to throw even your most seasoned programmers for a loop, throw a few rude triggers (like stuff that just ignores an update, but only between 9:00am and 9:10am on every other Tuesday, and only if the updated field is at least twice the pre-update value) in there.
Just playing with stupid fun examples in class, we did things that would have non-DBA programmers questioning their sanity and ready to drive off a cliff. It was fun, to tell the truth, and quite informative in a manner that will have me appreciating triggers for quite some time.
As someone trying to get Sybase ASE 12.5.3, WSAD 5.1.2, and a few other packages all running on a current distro of SuSE (either 9.0 Enterprise server, which Sybase doesn't play well with, or 9.3 Professional, which doesn't play well with Sybase and isn't a 'certified' platform for WSAD 5.1.2, or... well you get the idea) I assure you that this case will appear.
All the source code in the world isn't helping me get Sybase 12.5.3 working on SuSE 9.0 Enterprise Server.
Just curious - how do you rate LO:MAC vs. Falcon 4.0?
Only reason I ask this totally off topic question is that I have Falcon 4.0 (have for quite some time, but don't run it anymore) and am looking for something hot, fresh, state of the art - what do you suggest (air-combat sims, in particular, of the various era's (WWI/II and current/near future eras.)
Totally off topic, but odds are the people reading this thread know the answer :
I'm grew up in the Microsoft world of networking, and before that did lots of Netware - now I am dinking with Linux (SuSE 9.0 ES, and others) and one thing that I have yet to even see mentioned is how to configure 'network shares' or 'a shared file system' on Linux. How do I do the equivalent of the following in Linux: a) set up a particular directory tree on my Linux box as shared, b) configure rights for users that are not actually logged in to the box (not telnet'ed or SSH'ed or FTP'ed in, just 'connecting' their Linux box (or Windows box, for that matter) to my shared drive, and c) do the equiv of "C:\net use y: \\myLinuxBox\myShare" from my Linux box to the shared folder described in a) above.
I keep hearing 'use Linux as a server' but never 'use Linux as a file server' - implying that I can use it as an application server for web services or FTP or telnet or ssh or database server (all of which I have done, for fun or profit) but... what's the scoop on setting it up as a file server?
Yea I know, lamer - but if I don't ask, I won't know.
Yea, I was just messin' with GP / Chad. I'm guessing no relation, just two guys with good ideas at the same time. Only reason I said it was that both of them read more into my original post than I had written - I wasn't saying either technology or platform (commercial vs open source) was better, I was just saying that the big cost savings aren't found in per-seat licensing, the big cost savings is in more effective utilization of your employees.
The ones that said 'very wise, etc' are the ones that didn't read into my post that I was pro-commercial or anti-f/oss (good thing, because that's not the case) - they are the ones that agree that the savings of 'more work from the same number of employees' far outweighs the savings of 'per seat license costs'.

Umm - isn't Apache the web server part of IBM's WebSphere Application Server, which (last I heard) runs just fine and dandy on Windows servers.
