Tidbits from my experience working with public schools:
One response was, "We want to provide our students with real world business experiences. The real world uses MS Office."
Another difficulty with breaking away from MS Office are textbooks. The textbooks in our high school business department are written specifically for MS Office. Our teachers want to have the exact version of MS Office the text books are written to. (Also keep in mind that text book costs are much higher then computer and software costs.)
I've spent 4 moderation points on this thread but now thats all gone to waste. I want to reply to this.
I beleive you have made a mistake. The error you are recieving is due to a failed statement in your transaction. I have tested his example in 7.4.3 and found it to be correct. I even removed the sequences from the example and the block still happened. I don't know why the block is occuring. Maybe because the reference checks in both transactions are trying to read the same row? That doesn't right so I don't know.
As a previous post said, changing the isolation level will probably fix the problem. Here is the documentation.
Open System Preferences. Click on Accounts. You are shown a list of users accounts. Select the user account that you want to change. Click the Capabilities button. A pane will slide down reveiling options to limit a users capabilities. Under the section, "This user can," uncheck the box labeled, "Remove items from the Dock."
This works in 10.2. I haven't installed 10.3 yet.
This probably is not the solution you were looking for but I thought I would post it anyways. This option is more for machine admins. It enables them to place aliases on the dock for clueless users and then lock it so it doesn't get messed up.
I'm guessing (I'm not a developer, I'm just a "poweruser") a script could be written to quickly lock and unlock the dock. If you lock a users dock and then look at the users settings in netinfo you will notice a property called mcx_settings. The value for that setting is an xml plist file that locks the dock. Hack up a script that will change that setting then relaunch the dock then that should do it.
I would just like to point out that there has already been some live action work done with Evangelion. The original ending of The End of Evangelion was done in live action. Check this out.
Correct me if I'm wrong but that server is the root so IBM is the dot after.com. Not the dot before.com.
DNS can be thought of like a file system structure. In unix "/" is root. In DNS "." is root. After the root comes the top level domains like ".com" and ".net". No one ever types in the root dot. To type in the root dot would be to type in a dot after the TLD. like this "www.ibm.com." (The trailing dot is not a period, its the root dot.)
Providing a computer to every student and recreating the school system to use the technology could be very beneficial and could save a lot of money. For instance, computer systems and their networks are far cheaper then books. Electronic versions of text book could be much cheaper and more likely to be up to date. We are far from seeing something as cool as that in our schools. All those problems that the other readers brought up need to be addressed. You cannot just buy a bunch of laptops and throw them to the school.
What a coincidence! After pressing the submit button to submit the above comment, a page was returned with the Slashdot header but no other text. There was nothing that confirmed that my comment was accepted. Okay, the comment was accepted but at that point it appeared that the transaction had failed. I had no clue if I should click the back button and resubmit or what. The problem could have been with my Netscape browser or possibly a Slashdot glitch. Who knows but stuff like that is what contributes to my statement that, for me, something went wrong with over 25% of my transactions on the web. (BTW, I'm not complaining or anything. I'm just relating my experiences.)
I didn't spend the time to read the article but I can say that, for me, over 25% of online transactions have gone wrong. Poor interface or poor software on the venders end usually seems to be the problem. The problems I'm speaking about are with accually getting the transaction submitted. For instance, after filling out the web forms and pressing the submit button, a page is returned filled with MS SQL server errors. If I can get the sytem to accept the transaction, I normally don't have any problems.

My current employer uses an open source software package called IRM to perform help desk type functions. IRM is web based and uses MySQL and PHP.
