[ANN] Code Golf Challenge : 1,000 Digits Of Pi

[Carl Drinkwater]

Hi all,

Code Golf's 12th challenge has just been added to the site. It asks you
to calculate the first 1,000 digits of Pi - Something I'm sure most of
you have thought about, but never done. You can see the challenge at :

http://codegolf.com/1000-digits-of-pi

For those who haven't heard of codegolf.com, it can be described as
"allowing you to show off your code-fu by trying to solve coding
problems using the least number of keystrokes."

The site currently supports Perl, PHP, Python and Ruby with Scheme to
(hopefully) follow soon. Your entries are automatically executed and
scored - No need to wait for someone to validate your code.

Other challenges include implementing the Vigenere Cipher, Prime
factors, SHA-256 Hashing as well as the obvious 99 Bottles Of Beer. All
of the challenges are competitive but there is still scope to well in
them, even if you're new to the site.

I hope some of you will find this interesting, and sorry for disturbing
you if not!

Have fun,
Carl.

Here's a thought: for your next contest, why not issue a
challenge to see who can write a scoreboard
that actually works?

Is having good 'code-fu' worthwhile? It may be trivial to score but do
the results show who iss the better programmer?

Methinks I'll pass.

With Python you can't win, because Perl and Ruby allow for shorter
programs.
Beside the language, you win if you can invent more tricks, that you
have to avoid in real code, because it must be very readable.
The positive side of this game is that you exercise yourself, so you
get to know the programming language better, and you learn all the
corner cases of your language. Knowing them is useful, to avoid them
when you program for real, to avoid some kind of bugs generated by
corner cases.

Python has native bignums, which should simplify a program like this
enormously. I don't know if Ruby has them. Perl doesn't, and if you
use some CPAN library that simulates them, that should count as part
of your program size.

Unfortunately:

$ perl -Mbignum -e 'print

This is perl, v5.8.7 built for cygwin-thread-multi-64int
(with 1 registered patch, see perl -V for more detail)


Yep my standard Cygwin perl installation for windows includes the
bignum package.
