I began to take notes, the moment that i decided to be a programmer. I wanted to make a site with these notes but I couldn’t find the time to do this because I was new in my career. I was working and learning at the same time. I’ve been working for 1.5 years in this job. Now it is the time to share my notes. This was not my idea, in the beginning. I started to make this site with my notes because someone gave me this idea. He is the one who is my precious teacher, my colleague, my father. He taught me everything which i know now. By the way i want to thank my dear father here. Thank you so much, daddy. And i want to thank my mother for her endless patience, doing all the job in the home when we were hard working and for all those delicious foods when we were hungry. At last i want to thank my dear husband and my brother for their support, everytime.
