Git is cool!

Unix Shell

Shell is also cool! I will use it a lot in the future when I become web developer.

Git Collaboration

I like rebase command the most! It is the best!

Memory Management

1. Stack overflow.
2. Will be created anonymous memory mapping instead of using heap memory.
3. Text segment contains code which has been running and Data segment contains constant variables initialized by this code.

In this subject everything was new to me and hard to understand. But I think I get some basics.

TCP. UDP. Network

Almost everything except some basic things was new to me. I think it is very important for web developer to know how Internet works. And I am happy that I know some basics now.
