I have here a code which gives permutations for 10 lists. The code works fine for small number of lists with small number of values.
As soon as I try for 10 lists, it errors out with OOM : heap space.
Can one of you suggest optimizations for this piece of code?
public static <T> Collection<List<T
Original Problem
Short Summary:
Given a M possible characters all of which must be used at least once, find the number of possible combinations of length (exactly) K.
The stupid solution is to simply generate all possible repeated_permutations and then exclude the ones which do not use at l...
It always fascinated me how decoding jpeg files are done under the hood. So I decided to write a jpeg decoder from scratch to learn what's really happening. At first I wrote this in C# and then I converted it to Java. Here's the Java source code:

I am solving this question.
It's not the rivers that you might be thinking about. The question revolves around the concept of digital rivers.
A digital river is a sequence of numbers where the number

I am quite new to Python and I have trouble finding the roots of a function.
First a bit on what I want to do. The ultimate goal is to find $$y=(a_1,p_0,\theta)$$ such that they minimize the function $$-\sum\limits_{j=1}^{n} \ln(p_{1j}(a_1,p_0,\theta)).$$
For each possibility of \$a_1, p_0, \...

There is Codereview site. Why on earth does Stackoverflow need a code-review tag? I think it should be burninated. There is another question on this, but as far as I can tell, nothing has been done.

The ticker feeds in chat are interesting, but also annoying. One feature that would make them very nice is a face feature, where they fade away after displaying for N seconds (perhaps even user adjustable). As an example of this, I didn't clear my ticker for a while, and this is what I got:
I have a use case which says:
