Data Structure - Ruby

Hi Chris,

Could you help me with books, material, videos about Data Structure with Ruby? I have been asked a lot about it in the interview. I am rusty about it and there are tons of pieces about on the internet. It's like finding a needle in a haystack.

As I am not working now, I need to save time to relearn these topics without losing much time. I believe that this could help new programmer two who try to find this information here.

These are some topics that I am looking for.

1 - Solid understanding of programming and computer science fundamentals. What do they want me to know?
2 - Data Structure (list, stack, array, tree).
3 - With the data structure, how to search and sort with them. Best ways of searching and sort.
4 - Understand the Big Oh problem and how to identify and solve it.

Another topic that companies are asking for Senior Position (one day in the future)

5 - API design technique. What would it be?
6 - Strong familiarity with principles of database design and architecture.
7 - Familiarity with OWASP and/or other web security practices.
8 - Knowledge of optimization tactics such as query optimization and caching

Well, sorry for the book and thanks in advance for your help.

Hugs,
