The way of becoming a DM/DD?

[lumin <cdluminate@gmail.com>]

Hi there,

I want to take some action to participate in Debian,
but I don't know if I am on the right way.

I found some related resources here:
https://www.debian.org/devel/
and I want to know if I should read it __recursively__.

And following is my other questions :
1. What skill/ability should a DM/DD have?
   C lang? Data Structure? IP/TCP? Computer Organization ...
   namely, should I read all the basical computer science books?
2. UNIX/Linux C Programming skills in need?
3. POSIX standard?
4. Python/Perl? Shell?
5. Is picking an orphaned package a wise way to help?
   however, many orphaned packages are no longer productive,
   just like the "markdown" program witch is implemented in C.

Additionally, I have not subscribed the "debian-user" list, so please CC
me when replying.

Thank you very much.
