To summarise the articles: a bunch of small libraries providing object-based memory allocation and string handling.
Kudos to the poster for enabling himself to write code in a way that's good for him. But that doesn't mean it's good for anyone else.
For example, I'm not going to go and learn 20 more function names and have more library dependencies and I wouldn't recommend anyone else does either.
Finally, suppose one wants a better string library or memory library. There are already plenty of good, with-much-work-done-on-them, open source libraries out there. Tried and tested. Not to mention the C++ STL.
Pick one that means many other people will also be able to read your code and be familiar with the libraries you use! There's nothing I'd hate more than working on a project written by someone using these libraries. Not only do I have to analyze the code, I have to analyze these libraries, and also manage to keep them and their quirks in my head while I am reading the program. Yuck.
'computable' means that, given enough time, you can compute any one digit of it
(NOT necessarily compute ALL digits, as you seem to want to do).
Or, to put it another way, 'computable' means that there exists a function like this:
int find_nth_digit_of_pi(int n);
that returns after a finite time, if you call it once. Also note that this is a different property of numbers than the property 'can be written down in its entirety'.
a difference of less than 5 parts in 1000, or 0.5%.
So 355/113 is way more accurate than your representation. But in either case, you are missing the point: 355/113 is useful because it is easier to remember, and also importantly, the numbers are small so it is easy to use in calculations where you don't have a calculator.
Your love of the formulated text has clearly slowed your mind.
One bit is sufficient to encode pi, consider this algorithm (let's code it as a program called "punzip"), that works on a series of bits with a length:
1) if the first bit is 1, return pi [include some small algorithm in the decompression program to generate pi to the desired fixed length]
2) if the first bit is 0, discard it and send the rest of the input to "gunzip".
I'm sure you and I both could write this program in C (or even in shell script), as well as the "pzip".
Consider: 0.110100100100001000010000010000001.. . This has repeating digits (in some sense of the expression, anyway) but is irrational (perhaps someone could remind me of the proof). Finding this sort of pattern in pi would be groundbreaking for number theory, and is not ruled out by results such as 'pi is irrational'.
Not necessarily. Suppose that some sort of pattern is found after 10 trillion places, such that one could claim that all places are then known (in the same way that you can claim all the places of 1/3 are known). This search for patterns is surely the driving force of pi computation.
The poster comments that the anti-neutrinos seem to be disappearing.... dont know about you, but the first idea that occurred to me was that they would have met normal neutrinos and annihilated.
And before someone writes 'RTFA' (or 'Dont start a sentence with a conjunction'), I can't find it: the first link seems to be to the reserach centre's homepage, the second and third go to explanations of the standard model, and the fourth is broken.
I just read this first page (Introduction to 231Pu universe etc) and it is the biggest load of crap I've seen since creationism. I'm surprised the Swedish government allows the association of its TLD with this junk.
Why do I say this? I read the page, and see this guy making his claims. Where's his evidence? I scroll down some more waiting for the exposition to end and the science to start. Hmm, still none, still just more guff saying how clever the guy thinks he is. Whoops, it's the bottom of the page. Perhaps he should rename his site 'tabloidphysics.se'.
And the actual source material: He didn't actually say what his theory was, but I glark that he thinks the universe is an atom of plutonium, and the Milky Way is one of its electrons. Now, riddle me this. The universe has more than 94 galaxies. So, unless I've just busted his theory, I guess I haven't read far enough to reach the section where he rubbishes observational astronomy?
Everyone recognizes what a phone is... but the general public wouldn't recognize a split-second glimpse of a dotted-quad IP address; and those who do recognize the IP address are also likely to recognize what is a valid address and what isn't. Similarly, whoever designed that screen for the film is likely to have known what is a valid IP address and what isn't, if they knew enough to put an address in there.
On a different note, I guess your TV program because all the 555- phone numbers have been used up;) Maybe the movie phone system needs to move to PhoneV6
Actually, while I'm here, regarding the "Your Internet Connection is Not Optimized" message, does their software include features to disable seeing this popup once it's installed?
If you install their software and still get the "....Not Optimized" popup, then I think the lawsuit deserves to, and will, succeed.
Seen a lot of posts on this story but nobody has broached the second question that comes into my mind when I see these ads..
What does their software do to stop you 'broadcasting an IP address' ?
(The first question that comes to mind is, of course, what do they mean by 'broadcasting'; I would guess that they mean that if you go to a website then that website can see your IP. Hence my second question.)
Heh. Bernstein is cool. Although he uses dubious (IMHO) code practises, such as having entire functions with one-character names and all variables with one-character names, and calling _exit(), his code makes small executables (probably the lack of long debug symbols eh?) and doesnt have security holes.
Also he's prepared to tell dicks that they are dicks - something that is unfortunately rare these days.
Well, given the animosity to the big corporations that some posters have shown so far, this gives them the perfect opportunity to use up some of AOL's bandwidth
Come on, someone ask what this means so I can reply and get karma!

Certainly. Our experience also indicates that good play from both sides results in a draw -- usually, master games are drawn unless one side makes some sort of mistake, so perhaps it's nearly equally unlikely that white has a forced win as black has a furced win... but we will never know until the entire game tree has been mapped.
Note that although the tree is large (some say it's bigger than the universe), it may still be possible to generate it in sections at a time, and keep track of the results, with some yet-undiscovered cool-large-tree-traversal algorithm. I wouldn't completely rule this possibility out , especially with quantum computing.

Why is this bollocks?

You forget about 1/infinity
[Mod -1, Troll]
'computable' means that , given enough time, you can compute any given digit of it, which is certainly true for pi.
0.5 means 5 * 1/(base), ie. 5/2pi , which isn't pi.
:)
Perhaps you should have stuck to "2" (base pi/2)
Actually it isn't, for example:
Pi: 3.141592653....
355/113: 3.141592920....
a difference of less than 4 parts in 10 million, or 0.00004%
But:
Pi: 3.141592653...
3145926/1000000: 3.145926000....
a difference of less than 5 parts in 1000, or 0.5%.

That brings to mind the old conundrum,
"The smallest number that cannot be described in fewer than thirteen words"
(the catch, of course, being that that description has 12 words, thus describing the number that supposedly couldn't be described like that)
Well, yes it can
. .
Consider:
0.110100100100001000010000010000001.
This has repeating digits (in some sense of the expression, anyway) but is irrational (perhaps someone could remind me of the proof). Finding this sort of pattern in pi would be groundbreaking for number theory, and is not ruled out by results such as 'pi is irrational'.
He clearly meant 60 significant figures, which is just as precise regardless of what units you choose.
Not necessarily. Suppose that some sort of pattern is found after 10 trillion places, such that one could claim that all places are then known (in the same way that you can claim all the places of 1/3 are known). This search for patterns is surely the driving force of pi computation.

That wasn't a slip-up, it was an in-joke (in my opinion anyway). I noticed it the first time I saw the movie :)
Note - this is not a dupe
I feel that this is informative, due to the extremely high dupe story rate on slashdot in the last few days.

If confess() returns -1 then Mary will probably have an orgasm
Actually you can't, the guy was trolling.
Having the first moves is clearly an advantage in chess (that is to say, for strategic reasons, without knowing the entire game tree).
