I love this sort of thing:<p>> Be warned that 50 million digits of pi takes up 50 megabytes. This can take up to 4 hours to download with a 28.8k modem!
An idea I've had, the answer is most probably no, but I found it interesting to think about, others may find it trivial:<p>Is there a number that (1) contains most subsequences and where (2) finding a certain subsequence is computationally efficient? Also, (3) finding a subsequence given a starting and end position should be efficient. If so, we have a efficient mean to transfer data. Just send the index positions. And we can store any data with just those two index positions. Then again, those index numbers are likely to be very very large. Perhaps we can in turn transform the index positions to smaller index positions by finding their positions in the sequence. Then we need a third number to signify the number of recursive uses of the storage.

Interesting idea. Actually, just thinking, could be used for a pseudo-crypto app. Just send a series of origin numbers [n1,n2,n3...] and this translates to [pos1,pos2,pos3...] series of numbers. You can use also instead of Pi any other transcendental/irrational number [0].<p>[0] <a href="http://www.numberworld.org/digits/" rel="nofollow">http://www.numberworld.org/digits/</a>
So if I take the latest Lady Gaga mp3 and look at the stream of bytes, and if I can find that identical stream of digits in the digits of Pi, does Lady Gaga (or her record company) "own" that portion of Pi? If yes, then WTF!?!? If no, why not, and what does this mean for the idea of copyright, anyway?
> If, on the other hand, you act like a computer geek and use zero based indexing, then you get these numbers: 6, 27, 13598, 43611, 24643510<p>Heh, it says "act like a computer geek" and the numbers are not even in binary? :)
I wonder if there is not a bug in the decompress program:<p><pre><code> for (i = 0; i < FILE_SIZE; i++) {
printf("%d%d", (buf[i]&0xf0)>>4, buf[i] & 0xf);
}
</code></pre>
Shouldn't this be >>8 ?
Well mine isn't within the first 50 million. In any case, what's the relevance of this? Everything (with the correct encoding scheme) can be expressed somewhere in the decimal expansion of Pi.
