Actually, this property of numbers was a bit surprising, it turns out it doesn't have anything to do with the dates at all (of course). From playing around a bit more, I've discovered the following property of the number 9.
Any set of numbers whose digits add up to the same number, have a difference between each other whose digits will add up to a multiple of 9. This seems to work for any number. I haven't been able to find if this property was known or if I discovered something new. Probably its already known. Anyone know the name for it?
What is more interesting is this.

If anyone wants to take the time to work this out as an abstract algebra problem, I'd be curious to see how such a pattern emerges. You know, I get really tired of stupid Slashdot restrictions like this: "Your comment has too few characters per line (currently 9.1)." Then I have to add more useless text onto my post just so that it will accept a post that has some numerical analysis related to the article. While I can understand why they do these kinda checks, sometimes they are such a hassle. It still doesn't think I have enough characters per line. So I'm still adding text to this post. I thought it was kinda funny how they say in the article "a physicist at Germany's University of Aachen who crunched the numbers" as if the number crunching to calculate this was worthy of a super computer. I was able to make these calculations using num-utils, a couple of for loops and sed in about 5 minutes. Unfortunately, cal doesn't go past the year 9999. But oh well, at least its a nice accurate calendar. Well, its still telling me that I don't have enough characters per line (19.3 now). Sheesh. Probably now that I've put all this into my post, someone will mark me down as -1, Troll without really reading the comment and understanding what kind of hell I went through to get this posted on Friday the 13th.
I was just playing around with cal, reading the man page and found this:

That's a really weird month. Appearently, the September Massacres happened on September 2nd, 1752. Don't know if there is a relationship there.
Also, I was playing with for loops, numsum, sed and such and came up with this list of years that also had Friday 13th in October and all the numbers added up to 13.
80 125 170 215 332 422 1133 1223 1340 1430 2006
I'm not sure whether this is accurate though with respect to the change from Julian to Gregorian calendars though. 2006 marks the 11th time this happened since the year 1. Interestingly, the 13th occurance of this will be in 2141, which is also the last one that will occur in the 3rd millinium. The 14th one doesn't occur until 3122 and there are only 20 of them total in the first 10,000 years. I guess they are pretty rare. My wife and I have actually found the number 13 to be lucky for us more than unlucky. But they are just numbers.
- Play games (Tux Racer doesn't count) - Use Photoshop (don't say Gimp) - Use 3D Studio Max (yes, there are some alternatives, but 3ds Max is an industry standard) - Etc
What's funny is that you are obviously tired of hearing people respond with what software replaces Photoshop or Half Life 2, but I'm tired of hearing comments like yours, from people who haven't been paying attention to the Linux software world while its has been catching up over the past couple years. When it comes down to it all:
*Doom 3, UT2004 and other games come with Linux support (UT2004 came with it out of the box) *Gimp has color management support out of the box *Blender kicks ass and is no harder to learn that 3D Studio Max (Screw industry standards, isn't "the troubles of being locked in" what this article is about)
So I think nmb3000 and all the others like them can eat crow. Linux kicks ass. If you doubt it, keep the suggestions coming and OSS programers will keep track of them and fix those problems in a year or two and we can have the same argument again.
BTW, at work we bought 4 Dell 37" LCD TVs for a monitoring display. The Windows installation that came on the Dell PC that we bought with them had trouble recognizing the resolution for the TV. Linux OUT OF THE BOX did slightly better and at least gave me some higher resolution options than Windows did OUT OF THE BOX!
Pretty bad. You know, its comments like this (even in the semi-anonymous and lame-black-humor-filled world of Slashdot) that keeps our image down. No wonder most people don't care about our opinions and treat us with lack of respect.
I know you probably don't care and think that its not that big a deal to not give a rats ass about someone else's life, but for once the news of a murder really does relate to us and look at what you guys do. Show some respect, humanity and learn how to properly express it, even amongst your own kind. Seriously.
Actually, what is utterly ridiculous is that you folks take my comment(s) seriously. I was only being half serious on the observation that this is happening so close to elections. I don't really think that there is a conspiracy here and my comment title of "Mr. Conspiracy Theorist here" should have shown you that I was being silly.
I think you meant that headline to say "Bush administration secretly tells N. Korea to announce that they have conducted their first nuclear test before the November election".
and they are bad when overused. Its not a problem with geekspeak. There are often times when I am frustrated with people's overuse of acronyms, especially in non-computer environments. So don't blame us.
The Soviet military did not punish Petrov for his actions, but did not reward or honor him either. His actions had revealed imperfections in the Soviet military system which showed his superiors in a bad light. He was given a reprimand, officially for the improper filing of paperwork, and his once-promising military career came to an end. He was reassigned to a less sensitive post and ultimately retired from the military.
Honestly, I was intrigued a bit by the box when I was in EB last weekend and found a rather odd screenshot on the back showing Darth Vader's head on top of the body of Princess Leia's Jaba outfit holding a lightsaber. Subtle?
Another problem is that it's a big deal because the media makes it a big deal.
And the media makes it a big deal because the status quo for intellegence is not very high. Average Joe customer simply sees things on the surface and doesn't do any deep thinking. I remember hearing someone that I know say "I guess buying a diesel car is the way to go". No doubt he simply thought that because the price of gas on diesel cars was advertised as a few cents cheaper per gallon at the time. Now, its the opposite. And I don't know this for sure, but aren't diesel cars more expensive? If that's the case then you'd be losing money overall.
Perhaps the size of the price sign is what matters. Gas prices are shown in large high contrast fonts on every street corner. The price sticker on a bottle of shampoo is less noticeable or sometimes not noticeable at all. You just pick it up and put it in your cart.
In mathmatical terms, figuring that the price sign at a gas station is about 6 feet by 4 feet, and the price sticker on a shelf for a bottle of shampoo is 2 inches by 1 inch, the gas station sign is about 1,728 times larger and thus more emphasis is placed on the price of gas.
Its not for their husband's $55M, its for their late husband (Who was killed by the government)'s USD55,000,000.00 (FIFTY FIVE MILLION US DOLLARS) which they will deposit into your account
Obviously today is asshole moderation day. Since you are probably going to read this and moderate it down too, read this: People take the time out of their day to write comments that contribute in a positive way to Slashdot. Either by being funny, interesting or insightful. They are all important. When you mod those people down, you are making those people become frustrated with this site to go away and then everything goes south. Think next time, every time you mod a comment down that doesn't *need* to be modded down, you are helping to slowly lower the bar on what constitutes a worthy comment.
Why was the parent comment marked as Troll? He has a valid point. Its like how jBase (an obscure database no doubt) prides itself on getting to 64-bit in their latest version........ 10 years after all other enterprise databases did.
Adobe/Macromedia/Coke/Taco Bell: Come on, get with the program.

Data: "It is from an obscure language known as French"
