To calculate PI you use a series such as Maclaurin, noting that:
pi/4 = tan^-1(4)
So the Maclaurin series for tan^-1(x) is the following;
tan^-1(x) = x - x^3/3 + x^5/5 - x^7/7....
so using pi/4 = tan^-1(4) gives:
pi = 4[1 - 1/2 + 1/5 -1/7 +...]
Since this converges to slowly you can use the following identity to get more accuracy with less iterations:
pi/4 = tan^-1(1/2) + tan^-1(1/3)
This was obtained from my Calculus 5/E book by Howard Anton, Wiley publishing... This is one of my better text books, if your looking for a Calculus book for Uni, fully recommend...

A perpetual motion machine can't be patented in France, but can be every where else..
A perpetual motion machine breaks one of the fundamental laws of thermodynamics *hence
it is impossible*..
But why did the French not allow you to patatent a perpetual motion machine...
Not because they thought it was impossible, but because they thought it was so
important and to much of a benefit for mankind...
Sounds like a crap company to work for, suing your own worker after giving you heaps
of free advertising that you would normally pay millions for!!!
What a very tight A!#% company, really I don't see why they should
worry about some free feedback? Think about it, they could have used this ploy as a
advantage. I would love to know what the public thought of my product before I invested
millions and millions of dollars to get the production line going.
Or another scenario, like Intel.. Release heaps of hype about a product (which you may not deliver),
this might just persuade some customers to hold of buying another chip and wait for yours...
Can you help me... I have tried to install KDE beta4 (I tried SuSE, then Caldera version both to
no luck). Did you compile from scratch, or use some other distribution? KDE seems to stall on
the splash screen. I have loaded all the latest qt library, from the betas.
Aghhhh nothing like a nice Espresso...

Good to see that I am not wasting my time with a Espresso...
By the way I am always looking for a good place to get a good Espresso... So if you know of any in Melbourne (Australia) let me know, a have a couple but need more...
Also isn't there a double Jolt cola, with twice as much caffeine... Not that I like the stuff!!!
So once again just pass on down some good places for a Coffee in Melbourne, or for everyone else where you live!!!
So one would have thought this system to be a real contender!!! Considering the PCs are $1000 each and if we use 6000 of them, we would be able to afford 10 of these GS320 beasts (with a total of 320 alpha processors)...
Rule of thumb here.. Write two sets of code, one with utter drivel, the other well maintained. One you don't shoot yourself in the foot.. Two you have job security...
I am not saying Mac is crap, far from it!! I would love one, but in the end here in Australia they are far to dear to buy..
What good is it if your the only one in the street with it? Esp. if you are new to the system. What good is the system if you don't use it at work? What good is it if your friends don't have it? What good is it if you have allready got software for windows?
Hay, hope mac is arround for another day. But in the end Mac is just a small segment of the market, compared to PC's..
If your happy with mac good, I hope you stay with them.. But since hardly anyone is using them why the heck buy one?

New iMac Rolled Out

Alas, maybe here in Australia where the iMacs are around $2500!!! I know nobody who has one, and 100's that have PCS. I know of no school that is buying them (such as secondary, hay don't really seem them at Uni). If you can buy a window system for 1/2 the price, who the heck will buy your system? When half the software is not being written for you (so you have Microsoft office, but for how long). Hey, I love a mac! But when they are seriously out of my price rang (considering I have to buy new software), and I can get a lot better system from my corner shop for a far less price. Sure Macs selling heaps of iMacs for the short term, I don't believe this can substain.. Hopefully I am wrong, but in the end I don't really care as I wont be buying one.. my friends don't have one, I don't use it at work, I don't use it at uni, hay I don't use macs (as there is none around).

New iMac Rolled Out

When I was young, Apple IIe where all the rage. The schools had them, and everybody wanted one (heck even I wanted one). Alas years went by, and Apple still remained expensive (and other computers became more attractive). Who the heck wanted a small Mac classic that had a real bloody small monitor!!! (not me). This is where Apple had a superior operating system than Microsoft (good old dos and windows 3.1). What could have apple done? Start creating an operating system for IBM Compatible (heck theirs more money in it, look at Microsoft).
Ahh, then again if Apple started creating a operating system for the IBM's along time ago I would be typing in a Macintosh Operating System and then Apple Company would be the evil one.
I must say I like the look of the iMacs, except for price and limitations as monitors and no floppy drive standard. Then again since Schools aren't buying iMacs (or none that I know of), its only a matter of time before a Mac is a thing of the past a bit like a Amiga, Commodore 64....

Looking at information on the web about the new Compaq Wildfire series, surly they would be a sure contender..
You can look at the specs at:
Benchmark performance of GS320
Which says Suns EV10000 (64 processor) is not as fast as the 32 processor GS320....
And the price of the GS320 is estimated arround
$600,000 from:
The Register
So one would have thought this system to be a real contender!!! Considering the PCs are $1000 each and if we use 6000 of them, we would be able to afford 10 of these GS320 beasts (with a total of 320 alpha processors )...
