Just finished reading the book

Couple of days ago I finished reading the book "Advanced Linux Programming".
It is old but excellent book on programming in GNU/Linux environment. It starts from brief description of everyday developer's tools such as emacs, gcc, gdb, make and then leads to core topics of Linux development. It covers main system calls, IPC, networking, usage of shared libraries and plugins, error handling and so on.
So it is really useful for experienced developers and even for beginners because the text is very clear. There is no information on GUI development and minor libraries, so the book is very useful even six years after the publication.
It can be downloaded from the official site

I was doing some marks when reading, so I created some kind of reference card page on some covered in the book. You can find it here
