Just kidding.
Guys,
I shall be bringing tons of books (plenty of linuxjournal issues) and
quite a few textbooks that I no longer want.
I am deliberately avoiding listing all of them here.
A couple of samples.
a) Windows device driver development
b) Linux device driver development by Robert Love
and so on.
I dunno the algorithm on who will get what book.
I leave that headache to Bharathi.
See ya.
