These days I collected some documents about Linux Kernel. Though there are many great books about Linux, as Linus said, “RTFSC-Read The Fu*king Source Code.”, it’s hard to understand the design and implementation of the whole system without reading the source code.

But modern Linux Kernel is too huge, even 2.6 has millions of lines of code. Finally I found the tar ball for Linux 0.11 written by Linus Torvalds himself. It’s small, less than 20000 lines. However it is indeed useable and can be run as a complete operating system.
