I try to learn the GNU Assembler (as or gas) and I didn't found many resources but this book is great.

This is a 60% of the WIP (work in progress) for the project Programming from the ground up.

Goals:

• Programming from the ground up.
  • Convert the original DocBook to a Markdown then with pandoc convert it to ePUB, MOBI and PDF.
  • Improve and update the sections where I am missing.
  • Try to fix the bugs and support tickets, since 2004 is not updated this book.
• Programming under hood.
  • Convert the original LaTeX to a Markdown then with pandoc then convert it to ePUB, MOBI and PDF.
• Final version.
  • Create a version for x64 architecture.
• Create my own book based in the experience that I gained in this project. It should will in a new GitHub repository.

You're able to find my documents about assembly in my GitHub repository airvzxf/assembly also I was working in some assembler scripts that I wrote based on the exercises of this book. It contains a Linux shell script to make all the binaries straightforward.

• I believe that Linux is the future, I dream with a world when everyone is using Linux in our laptops, desktop computers, and all the video game companies make perfect games for Linux.
• I was researching about GNU Assembler (“as” or “gas”) but unfortunately, there are not many resources, these resources talk about the most popular as “NASM” and “FASM”.
• Why NOT focus on “NASM” or “FASM”? I started with “NASM” then I saw a few years ago the active development stopped. I researched about “FASM” and looks like it's awesome but then I discovered some curious detail. These assemblers can compile in many architectures and it is powerful but trying to be very compatible they spend a lot of effort to create the most generic binary source possible (1). At this moment I start to consider the possibility to use the pure Linux assembler because for me the idea to use a multi-architectural assembler is only marketing. I have been software developer over 14 years and I never created a multi-architecture system neither in my personal projects. Why am I living in a utopia? Wanted a tool to convert to other architectures, if I always create programs for Linux and very rarely for Windows. In these cases I usually use Python or Java. Note: This is my personal point of view, haters please hate more.
• Why use Assembler rather other languages programs? The benchmarks that I did demonstrate that Assembler is the most powerful even tan C which is the top language. My benchmarks and the C benchmarks.
• Why update this book? This book is one of the best that I found but it has many areas of opportunity. I read until the chapter 3 and I had three doubts in the final exercises but there are no answers. The book said that we saw this subject and I reviewed all the chapters and it didn't.
• Deep thanks to the men and companies who inspired me to be better and thanks to the Open Source: Linus Torvalds, Richard Stallman, Linux, GNU, GitHub.

• Download the original source code.
• Figured out how to compile the source code.
  • It's not easy and needs to install some packages also I couldn't compile the book. Other reason is that the DSSSL is an old technology.
• Make decisions if keeps this format or use other tools/format.
  • Use pandoc (official project) to convert the original DocBook to Markdown format.
    • Fix all the conversions failures.
      • Footnotes needs to create a new numeration.
      • Internal broken links for references.
      • Styles and formats.
      • Create a ToC (Table of contents).
    • Export to the final version to ePUB.
    • Export to the final version to MOBI for Kindle.
• Start with the TO-DO's file.
