Do you believe it ? Try like that in terminal. Linux can’t teach you about love, peace , happiness. But he can teach how to kill ? If you don’t know how to kill , try

$man kill

( just kidding…. kill also have in Mac <strong>kill</strong> — terminate or signal a process )

Today, I am testing Android OS. I tested and I don’t like it because it’s a smart phone OS. I can’t use mouse on that. I just use arrow key from keyboard for navigate. How stupid it that ? It may be design for touch screen. My laptop is not touch screen. So, I can’t use well. Sometime, I forget and moving mouse haha…. Some message show and I left click the mouse and no happen…. So funny… I forget, I can’t use mouse in their. I think it’s not suitable for Computer OS, now. They can’t compare Windows and also Ubuntu.

Android includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language.
