Ships from and sold by Nature Reading. Dan Barrett has been immersed in Internet technology since 985. For the price, the students will thank you too. 5.0 out of 5 stars Great buy for the Linux beginner, and good high level reference we& 39;ve not seen a problem - both are Linux and conform to the POSIX standard.
