As you already may know, I've started a series of [blog posts](http://0xax.github.io/categories/assembly/) about assembler programming for `x86_64` architecture in the last year. I have never written a line of low-level code before this moment, except for a couple of toy `Hello World` examples in university. It was a long time ago and, as I already said, I didn't write low-level code at all. Some time ago I became interested in such things. I understood that I can write programs, but didn't actually understand how my program is arranged.
如你所知，我从去年开始写了一系列关于 `x86_64` 架构汇编语言程序设计的[博文](http://0xax.github.io/categories/assembly/)。除了大学期间写过一些 `Hello World` 这样的玩具例程之外，我从来没写过哪怕一行的底层代码。那些例程也是很久以前的事情了，就像我刚才说的，我几乎完全没有写过底层代码。直到不久前，我才开始对这些事情感兴趣，因为我意识到我虽然可以写出程序，但是我却不知道我的程序是怎样被组织运行的。

After writing some assembler code I began to understand how my program looks after compilation, **approximately**. But anyway, I didn't understand many other things. For example: what occurs when the `syscall` instruction is executed in my assembler, what occurs when the `printf` function starts to work or how can my program talk with other computers via network. [Assembler](https://en.wikipedia.org/wiki/Assembly_language#Assembler) programming language didn't give me answers to my questions and I decided to go deeper in my research. I started to learn from the source code of the Linux kernel and tried to understand the things that I'm interested in. The source code of the Linux kernel didn't give me the answers to **all** of my questions, but now my knowledge about the Linux kernel and the processes around it is much better.
在写了一些汇编代码之后，我开始**大致**了解了程序在编译之后会变成什么样子。尽管如此，还是有很多其他的东西我不能够理解。例如：当 `syscall` 指令在我的汇编程序内执行时究竟发生了什么，当 `printf` 函数开始工作时又发生了什么，还有，我的程序是如何通过网络与其他计算机进行通信的。[汇编](https://en.wikipedia.org/wiki/Assembly_language#Assembler)语言并没有为这些问题带来答案，于是我决定做一番深入研究。我开始学习 Linux 内核的源代码，并且尝试着理解那些让我感兴趣的东西。然而 Linux 内核源代码也没有解答我**所有的**问题，不过我自身关于 Linux 内核及其外围流程的知识确实掌握的更好了。
