Mongo is document-oriented, not relational. You do realize that the two architectures serve completely different purposes right? I wouldn't bet that Mongo would be the right choice for a high-volume OLTP environment.
"They probably didn't even know they were below sea level."
Are you serious? Have you ever been to New Orleans?
Only a blind person would not realize that they were below sea level. During the late spring and summer months, if you look at the levee, you can clearly see that the water level is above the city; even from a mile away you can see ships going down the Mississippi that are sailing higher than the city level of New Orleans. If you look down on the river while driving over the Crescent City Connection, you'll see that the river is close to the levee tops; the water-line is almost always above the city during this time of year.
Sorry, but I can't agree with you on this. Just because the number of alternatives will shrink, this doesn't mean that there still aren't a slew of alternatives and would make Oracle a monopoly on the RDBMS market. Think of MS SQL Server, IBM DB2, Sybase, Informix, Teradata....for FOSS, think of Postgres, Firebird, even SQLite.
As a DBA, I agree with this. I'm constantly being hounded by salesmen touting their OLTP numbers. I, for one, am glad that this was brought to my attention; it will give me more solid information to use when countering their arguments, as well as forcing them to watch their advertised stats move closely.
Not so sure about Engineering majors being included in the Linux crowd....AutoCAD is pretty much a standard for design/drafting, and runs exclusively on Windows (Unix/Mac support was dropped years ago). I know that there are other software packages out there with similar functionality, but AutoCAD has a very firm grip in this market segment. This forced me to disregard Linux as my main OS during college, even though Linux was very popular with the Computer Science majors.
Just because the Computer Science department or University as a whole supports Linux doesn't mean that certain departments will have to use it, since certain software will require Windows....this will depend on your major. I'm sure this applies to other majors besides Engineering....maybe film students will use Final Cut? I can't think of any others...
I usually don't respond to AC's but since I did RTFA:

Touche'. I have used my iPhone in the rain a few times, and the moisture sensors have still never been tripped; I guess the point I was trying to make is that you can't trust users anymore than you can trust Apple's PR department.
Agreed. My wife works at an Apple retail store. You wouldn't believe the number of people who get their phone wet, and then deny doing so. A guy brought his 12 year old daughters phone into the store (why a 12 year old needs an iPhone is a different story all together). This phone obviously had water-damage, but the father denied it till the end...even after my wife managed to get the daughter to fess up after asking her a few questions. Even though the daughter admitted to dropping her phone in a vat of gatorade, the father still believed that this was not their problem and insisted that this was a hardware fault.
In another case, a woman was talking on her phone in front of the store....in the rain. After taking it in, my wife looked at it and informed her of the obvious water damage. This lady completely denied ever having this phone come into contact with water, even after my wife stated that she just saw her using it in the rain. This lady stormed out of the store, and immediately called someone on the phone....while standing in the rain again.
A guy I work with dropped his phone in the ocean and it immediately quit working. He made an appointment, went to the store, and was completely honest about what happened with the sales rep (not my wife). They comped his replacement phone for him. Moral of the story is, if you're honest and polite, you may get more help than if you go into the store and whine, complain, lie, and curse at the top of your lungs, which is probably happening in most of these exploding battery scenarios.
What kinda bites is that one of the plot gimmicks is the mind control of robot/avatar, which makes it similar to Surrogate (with Bruce Willis). I'm worried that this will make Surrogate seem kinda like a knock-off of Avatar, which is a shame because I think Surrogate is poised to be one of the best Sci-fi movies on 2009.
"SDL changed its company-name to "Relational Software, Inc." (RSI) and introduced its product Oracle V2 as an early commercially-available relational database system. The version did not support transactions, but implemented the basic SQL functionality of queries and joins. (RSI never released a version 1 - instead calling the first version version 2 as a marketing gimmick"
My favorite has always been Oracle. The first commercial release of their flagship DB was version 2.0. There wasn't a version 1 because they wanted the product to sound more mature.
I'm really surprised to hear this. I had an HTC Apache with Windows Mobile 6. I pretty much had to follow this daily ritual:
1) Constantly closing background apps to keep the phone from crawling to a snails' pace.
2) Rebooting the phone at least 3 times daily.
3) Having to turn-off 3G to make sure I would get more than 4 hours of battery life.
4) Turn off any form of push e-mail whatsoever. See #3.
Keep in mind that this was with the regular first-party MS apps included with the OS (IE, Notepad, etc). Everyone I've talked to that has had a Windows Mobile phone has had the same experience. Either you're really lucky, or you've got some magic touch that the rest of us desperately needed.
Did you still attend even though you were a contracter? Doesn't matter if you were or not, I'm sure that trying to force you to attend is highly illegal...
Man that is a lame argument. Did you know that more Germans died in WWII (7+ million) than Jews in the Holocaust (if you use the common 6 million number). Judging by the sarcasm in your argument (I could be wrong), it wasn't OK to kill that many Germans to end the Holocaust.
2 of the hosts have 128 GB of RAM with 4-way quad-core CPUs.
I'm not sure of the other three off-hand, but they are older...4-way hyper-threaded CPUs, not sure on the RAM. These are going to be replaced shortly.
Memory size defined for the guest varies by function (SQL Server, application server, etc)....Typically 1 GB.
The part about spending taxpayers money is spot on. I used to do work with state revenue agencies. In every case, with every agency I went to, they had a Z-Series installed and were trying to move to x86 hardware. The main reason they had the big iron to begin with was to support legacy software that had been in production for the past 20+ years. The two main reasons for wanting to abandon it were:
1. The cost of maintaining said software cost more on an annual basis than it was to rewrite from scratch using RAD tools. 2. Cost of operating said mainframe was also in the same ballpark. IBM would charge these guys for CPU cycles used every month.
Also, COBOL programmers are reaching retirement age and aren't that easy to come by nowadays;-)
I work in a fairly large ESX shop with about 300 guest VM's on five host. If you just price the hardware, I'm sure it's below the $100,000 mark....including the iSCSI array. I'd imagine that a Z-Series mainframe capable of handling 300 VM's probably cost twice that. If you have to replace a part, it's not cheap to get IBM onsite to replace it for you since doing it yourself isn't really an option.
"But mainframes are more reliable"....is this really the case, and at what cost? With stuff like VMotion and LiveMotion, you can lose an entire host and your guest VM's are migrated to another. With good equipment, this would rarely happen anyway (a lot of x86 servers are built with redundant parts nowadays, you know).
I remember reading on ArsTechnica about a 2 years ago that there are currently only about 10,000 Z-Series installs worldwide. That doesn't mean there is much of a current market for this, and I'm sure that after you factor in licensing, hardware, and support, migrating to something like this would cost a small fortune.

douche.
"Windows 7, on the other hand, remains the corporate standard"
That's fast, considering it was just RTM'd a few weeks ago and won't see a general release until Oct. 22nd.
Even though I wrote the semi-parent reply, I think you should be modded funny :)

Man, the jokes are going to start pouring in:
"Now that's government transparency"
"After exposing the location of the vice-presidential bunker earlier this year, Joe Biden also forgot to uninstall Limewire from his netbook"
Yeah, and this is not long after Putin told Michael Dell that they are not "invalids" and didn't need help.

From Wikipedia, take it for what it's worth.
http://en.wikipedia.org/wiki/Oracle_Database
The CIA-funded project which was code named "Oracle" was produced by Ampex.
My favorite has always been Oracle. The first commercial release of their flagship DB was version 2.0. There wasn't a version 1 because they wanted the product to sound more mature.
It would be kinda hard to kill since the code is already "open" and out in the wild. Oracle can't prevent the current code base from being forked.
