 After writing some assembler code I began to understand how my program looks after compilation, **approximately**. But anyway, I didn't understand many different things. For example: what occurs when the `syscall` instruction executed in my assembler, what occurs when the `printf` function starts to work, how does my program can talk with other computer via network and many many other cases. [Assembler](https://en.wikipedia.org/wiki/Assembly_language#Assembler) programming language didn't give me answers on my questions and I decided to go deeper in my research. I started to learn source code of the Linux kernel and tried to understant things that I'm interested. Source code of the Linux kernel didn't give me answers on **all** of my questions, but now my knowledgesis about the Linux kernel and processes around it is much better.
 
-I'm writing this part after nine and a half months since I have started to learn source code of the Linux kernel and publish first [part](https://0xax.gitbooks.io/linux-insides/content/Booting/linux-bootstrap-1.html) of this book. Now it contains forty parts and it is not the end. I decided to write this series about the Linux kernel mostly for myself. As you know the Linux kernel is very huge piece of code and it is very easy to forget what does this or that part of the Linux kernel mean and how does it implemented. But soon the [linux-insides](https://github.com/0xAX/linux-insides) repo become popular and after nine months it has `9096` stars:
