Something related to C and C++

Mon Mar 17 23:55:04 UTC 2014

I got no chance to learn in college, cause I will graduate this summer and I want find a job Unix-related, C-related, in my college, I had not learn much in C and Unix, cause my college use Windows, and not focus on C-related, and for me, I start learning these this year, and I think I prefer read books just a little everyday, it can make me continuously familiar with these material which I like work on.
I got four books in my hand now:
C related, Unix related, FreeBSD related, and C++ related.
And I think that the src in FreeBSD base system is a good way to practice C, like some simple utilities: echo, ls, etc. And FreeBSD got many historical docs in base system, and I think it is a great way to understand FreeBSD or Unix world more.
The only problem is that, I find no passion if I just learn, maybe this will change after I got a related job.
