Subject: RE: [PATCH] playlist and id3 fixes
From: Jeff Waltzer (jeffwaltzer_at_yahoo.com)
Date: 2002-07-22


    Did a little research with Google and found this link:
http://softwaredev.earthweb.com/sdtech/article/0,,12065_616221_2,00.html

It recommends using (quoting from article)
> for (i is 1 to 3)
> Swap i with random position between i and 3

Instead of
> for (i is 1 to n)
> Swap i with random position between 1 and n

(The change is the range starts with 'i' not '1')

   But then when all is said and done it probably doesn't make that much
of a difference.
