Passing Password to SCP with expect (single line)
scp is used to perform secure copy between different hosts. By default, scp doesn’t let you pass password as a parameter.

For The Love of Fractals
I have been lurking around /r/FractalPorn so much that I finally decided to put my love for Fractals down on words. These structures are hauntingly beautiful and on this post, I want to share their beauty with you. Although not as technical as previous posts, it should be interesting nonetheless.
