There is a near-infinite amount of ways a computer can be broken into. But that does not mean that there isn't a reason to secure our computers as best as we possibly can. It's like the principles of a secure house. Which are the most secure houses? The ones with locks and adv ...more

One of the main reasons I was held back from fully switching over to Linux was the fact that media streaming is nearly impossible. You have two choices in Windows: either you use file sharing with Windows Media Player, or you can just use the Windows Media Center. But both of ...more
