in reply to one-liner hogs

How about this for processor churn?
perl -e '$_="abcd"x100000;while(1){y/abcd/bcda/}'
perl -e '@_=0..1000000;while(1){foreach(@_){++$_,--$_}}'
perl -e '@_=0..100000;while(1){foreach(@_){$a=$_/++$_;--$_}}'

The first exercises about about 8MB of memory fairly heavily.
The second beats up 64MB of memory with light mathops.
The third eats 9MB with a heavier math op.

Obviously you can tweak how much memory is eaten with monster number in there... HTH.

$you = new YOU;
honk() if $you->love(perl)

[erix]: ITYM Schwartzian Transform :P
[erix]: hey planetscape :)
[planetscape]: howdy stonecolddevin, erix
[Sinistral]: eric Aye. I thought I typed that wrong. All hail Randall! I listen to him on FLOSS Weekly
[Discipulus]: i think his vacuus, trombon like, absence of meaning, joined with a ostentatious style, after many years irritates the most
[erix]: easy to get wrong -- I guess that was sund's point, too :P
