I am testing/searching tests for my image manipulation algorithm and I have come across to "lena.png" multiple times. Why? Is it some kind of standard algorithm testing picture? I would like to know the history behind the picture.
Is there other similars pictures I could use? Why?

Is there a way to pull a random element from a list? Like say, picking a random name from a list of 10 names.
You can use Array#sample if the list is an array:
names.sample
Otherwise, if it's a string, you can convert it into an array first:
names.split.sample

The following link mentions some types of dynamic programming:
http://www.mii.lt/olympiads_in_informatics/pdf/INFOL056.pdf
one of which is "broken profile".
I am pretty sure it is a valid term since I have seen references to it in other programming competition sites like TopCoder and CodeForces.
But I can't seem to find anything on this topic. This term has been used mostly by Russian sources.
Does anyone what if means, or what kind of problems within dynamic programming it solves? Or even better a tutorial?
