I am currently looking into  what Ralf has said! Now, I am going through
the documentation..
So, how far I should be reading the source-code of the project before
proceeding with the bugs? I seriously feel reading code is a very tough

Actually, I am going ahead for Signals module is because I study
Electronics and DSP is the area where I like to specialize.. However, I am
very open to other projects too.. I just want to get involved in a
beautiful Scientific Project and improve coding skills

Looking into it now! This website looks very simple. May be we can try to
use Twitter Bootstrap... Its UI is quite attractive and even simple to

What do you say?

Probably I might propose new ideas if I look into the Django Stuff (the
development part).
