Finally, after quite a long awaiting, I’ve enrolled to Interacting System class. And perhaps this is one of my most favorite class amongst the other classes 
I will learn more about UNIX and how system works. It is quite an excitement for me to know that I can enroll in and get knowing more about Operating System.
I’ll use this blog to post more information about UNIX and other information that I got from the class.
Cheers!
