In addition to learning C++ and Qt I also started to learn assembly language. I spend much of my free time reading the book Professional Assembly Language. You learn quite a bit about how processors work and how to use them at a very low level. It is also great that the authors use open source Linux tools like assembler GAS and debugger GDB. I have everything installed and ready so it is just perfect. What I miss in the book is more info about additional features available in AMD64 architecture. For that I will have to check out the documentation provided by AMD.

And why did I decide to start learning assembly language in the first place? There is a popular collection of Slovenian dictionaries from Amebis, but no application for Linux exists. So I decided to try to find out how the Windows application ASP32 opens the files. If I manage to do that I could then try to write a Linux program to do the same thing. Even if I fail the knowledge of assembly language will remain and you never know when it will come in handy. May it be just for a better understanding of compilers or knowing how to better optimize some demanding function.
