Xerox? So you have one original and 4 copies in different places? What happens if you change on of the copies, suppose you blackline a paragraph on one xerox copy. Ooops, there goes the real world analogy, because now you either have 3 copies and a new version or you have a dedicated secratary that updates the other 3 copies and the original with your change. Realworld stuff can't exist in multiple places.
So, if I choose 'Save As' and place my opened document in a new place it writes it in the same place on the harddrive? Maybe I'm not understanding what you're saying, but just because I can use links how many users actually do that? 'Save As' writes a copy to a new place on the harddrive, but now you have new information. If you want to delete/change this file, the other copies will remain unchanged. If you somehow use links, then you still run the risk of deleting the original and losing all information AND you are inconveniencing your self for the sake of an unintuitive filesystem.
I've seen the same file in multiple places on harddrives and each of them is taking up their own real estate. What you've seen are multiple copies of the same file.
I'll second the Wight patterson air force base. THat's a great place to go.
I'm surprised that nobody's mentioned it, but the Corning museum of glass is the best museum that I've been to. It's in Corning New York and it's an impressive selection of art, science, and technology. Although I could spend 3 full days at this museum, I have a masters degree in Ceramics. A typical person could spend one full day, because there is so much. The museum does a great deal with manufacturing of glass, there's multiple glass blowing demonstrations throughout the day, great glass sculptures by all of the best artist (including the best Dale Chihuly piece outside of Las Vegas), and lots of hands-on science stuff.
I used to work for Lockheed Martin in their postal distribution technologies department (Owego, NY). Believe it or not, some of my code is on all of the USPS and UK Post's sorting machines. We used a very simple nueral network along with a good feature selection and a few tweaks to detect and record postage for all USPS and UK mail. That was fun and the all of the distribution machines were impressive. I second the post office idea.
Another fun idea would be to visit a prototyping plant. Often these have more secrecy than production plants, but IMHO the prototyping plants are more interesting. There are large stereography machines that are basically gigantic 3D printers. You'll find large devices that drag tiny needles all over a surface, recording dimensions. The prototyping plant I worked at had the largest wood workshop that I've ever seen. They designed prototype airintake manifolds, and castings often start out as a wooden model. Other parts of the plant included huge CNC lathes that you could park a car under and a various injection molding tools/dies/machines. They also had a blow-form machine that would take tiny little plastic slugs and inflate them into water containers, 2Liter soda bottles, anything.
Tours of manufacturing plants are definietly cool.
Your argument, like the first paragraph of the Forbes article, is mostly flawed. By stating the composition of the 234 US billionaires, you are not really stating anything. 234 people in the US are exceptions, not the norm. If you want to become *rich*, then you need to look at the makeup of all of the poeple that you define to be *rich*. Even this logic has a subtle flaw: to become a member of a group, your don't mimic group members' traits, but rather you maximize the likelyhood of being accepted in the group. More specifically, this says that "Who cares about USA's 234 richest people? I just want to maximize my earnings!"
If you're life is similar to a particular person in this group, then you may choose to emulate their habits. For example, a shrewd programmer with good business skills might choose to follow Bill Gates' path to riches, because you are suited for this and Gates has a *proven* path to riches. However, the Forbes article misses this entirely by analysing the *statistics* of all 234 billionares, not to mention that things have changed entirely for business in the last 20 years for any *single* billionare.
I do agree with your point, pamri. I believe that education (not bookish education and not even college education) is a great way to maximize one's earning potential. To get somebody to utilize this potential is another story altogether.
But, articles studying the worlds richest people are for dreamers who like to purchase lottery tickets.

RubyCocoa is a Mac OS X framework that allows Cocoa programming in the Object-Oriented Scripting Language Ruby. RubyCocoa allows writing a Cocoa application in Ruby. It allows creating and using a Cocoa object in a Ruby script. In Cocoa application, mixture of program written by both Ruby and Objective-C is possible.
I heard that Ruby was mostly popular over in Japan, but I didn't expect this kind of Engrish at Sourceforge!
Perhaps my math isnt high enough yet (Math Analysis (Trig) in High school currently). Isnt it being a prime number just a label?
Prime numbers are *extremely* significant in mathematics. Prime numbers are one of the most fundamental ideas in set theory. It turns out that it doesn't matter what base number system you use, or if you even use numbers or finite sets, you will end up with some form of prime numbers (or prime cardinality).
The idea of primality is a very basic concept in mathematics and it lies very close to the fundamentals of logic and set theory. You mention that you are in high school, but if you are interested in reading more, I suggest reading something from an Abstract Algebra website or text book. Abstract algebra is a college level math course, that could be understood easily by an interested and motivated high school student. No calculus or prior college math is necessary to understand Abstract Algebra, although a highschool geometry course might help you with the concepts of theorems and proofs.
Everyone seems to be focused on the negative. There would a somewhat positive gain out of such a merger.
The positive gain? MS Frontpage might just go away. Even if Frontpage wasn't replaced by Dreamweaver, I'm sure that the Dreamweaver influence would be good for Frontpage.
I stand corrected. I'm sorry for my american-centric view. I work on "the street" so I should have realized. Actually, I will be looking for work in London/Frankfurt as soon as I finish up my Quant-finance MS.
You're right. Excel may be far less prevalent elsewhere in the world, although I can't imagine what might take its place. I would be interested in knowing.
Such a system is capable of high bandwidth, but the latency sucks. Especially during lunch time and afternoon break time.
Tri-Delta girls aren't particularly good girls with regards to networks. Remember that 2 out of 3 go down (an classic joke refering to their logo). Do you really want a 66% system failure rate with your network?
...but for quant jockeying, where you actually manipulate data, it's far too 2D. Also, people discover excel has only 65535 rows and decide it sucks.
Plus excel runs neither on commercial unix nor IBM motherfuckin' mainframes, so lots of banks won't use it for anything mission critical. Traders tend to be tech-savvy, and here (City) insist on APL on Unix on their desktops - Most of the quants I know use an APL2 family language like Saxon APL or an asciified derivative thereof like K.
2D is all that you need for traders' on-screen analysis. It is simple, quick, down-and-dirty, and gets the job done. If you are doing anything with even close to 65535 rows, or if you need a 3+ Dimensional data structure then you need to reevaluate your model and your decision to use Excel. There are many tools (Matlab, SAS, C++, Perl) that better suited for large data sets. Pricing Options, Derivitaves and Bonds doesn't require these models.
With regard to banks using Excel. I was refering specifically to supporting traders in investment banks. I'm not sure what is run serverside, but I hope it is mission critical. I know that *all* of the quants and risk analysts that I know use excel. Some of them have Sun compute servers with SAS and Matlab, but Excel is the dominant tool and the tools that they develop for traders *have* to work in excel.
You say that you work at city. Do you mean Citi? (Citigroup). If this is the case, your misspelling makes me doubt that you really work in the finance industry.
I agree. Also, we can't fault Apple with *trying* the GPL. People can get mad at apple for being to restrictive with which code can be licensed in which way. But name one other company that has attempted to embrace the GPL with their own code that wasn't already under the GPL.
Or even easier, name one non-Linux company that has embraced the GPL at all.
Apple is trying something new. As they decide what they feel comfortable releasing and retracting, they will make mistakes. Some of their decisions will be marketing related, some will be legal related, and we may not be happy with many of the decisions... but at least they are trying. The best that we can do is constructively support and offer recommendations.

I paid $50 for.mac and, except for the 1 week of server upgrades, I haven't noticed any downtime. I check my.mac email periodically throughout the day from work (via webmail.mac.com) and when I'm home, my laptop is constantly checking email.
Even during the server upgrades, I only noticed two afternoons which webmail was down.
I actually switched my ISP to forward emails to my.mac account because I perceived.mac to be more reliable than my ISP. I'm going to reevaluate this decision once I read some of the other comments of this Slashdot story.
All in all, I've been happy with.mac, especially the email/iChat/iPhoto-galleries aspect of.mac.

Do not confuse computional/mathematical representation/aproximation/generation with the real world.
Whoa!! Your crazy way of thinking seems so new and revolutionary to me.
Seriously, though, fjords can be approximated by fractals. To show this, all one needs to do is implement a fractal box counting algorithm to the image in question. Fractal box counting will show that the fjords have a boundary that is approximately 1.4 dimensions (rather than the typical 1-dimensional boundary of a circle or square) and thus, can not be measured with a finite 1-dimensional measure such as length. Thus the coastline length can be approximated by infinity. Everybody knows that anything remotely close to infinity is still infinity (e.g. \infty - 1,000,000,000 is still infinity), thus the coastline is infinitely long, at least in 1-D.
This message is a queue for all of the Dynamical Systems Mathematicians to step in and correct me (although I think I am correct).
The West Fjords are a series of peninsulas in northwestern Iceland. They represent less than one-eighth the country's land area, but their jagged perimeter accounts for more than half of Iceland's total coastline.
I'm surprised that I am the only one to point this out: How can the fjords represent 1/2 of Iceland's coastline when they have a inifinite length (due to being fractal)?? Please advise.
...but how will current SetTopBox monopolies take the news?
Easy. They will do what all monopolies do when competition enters their markets. They will either squash Sony's box through legislation or deals with the cable companies, or, they will lower their prices.
Screw all of the other data mentioned above! I want to run pricing models on historic financial data... e.g. intraday option prices and vols, dividend schedules 30 years back, intraday stock prices for way back.
This is stuff you can't download for free from Yahoo, CBOE, or other places.
If I can just get access to this data, then I will make enough money to purchase the other data.

I agree with your comment 2nd Post!.
I have some specialized uses for my 667MHz G4 Powerbook, so let me add my thoughts...
For 99% of what I do, OS X is fast enough. I'm a part-time graduate student in quantitative finance, and I used to run a lot of financial simulations in Octave in OS 10.1 and Redhat 7.3 (P3 550MHz, 512MB). I found the G4 to consistently be twice as fast as the P3. My Octave option pricing programs would consistently run in 1/2 the time on the laptop as they did on my P3. The only time that the P3 had any significant advantage was when there was a lot of file i/o in the octave programs, where my SCSI drives would become all stars. These estimates are based on measurements built into the Octave program.
For excel, however, my Powerbook is weak. For my current job, we run a lot of Pricing models in excel, and something as simple as solver crawls on my PowerBook. I would say that solver takes 10 times as long to find a solution on the G4 as it did on my P3 (this is a guess, I didn't measure the time).
For *everything* else, my powerbook shines! I know that it doesn't say much to compare an old P3 to newer mac, but the P3 was good enough for my programming/graphics/needs and the
