How to randomize?

[JosAH]

If you were the instructor, that would have been a very interesting class.

Please spare me; I just have a few rules:

1) as I said: I hate digging through all those off-by-one errors; re-use code which
we can asume to be correct;
2) I'm the only one allowed to smoke in the classroom;
3) when I appear to be asleep I don't sleep; I'm thinking.
4) when I wear a paper brown hat over my head it's none of your business.

kind regards,

Jos ;-)
