My friends with non tech background thinks that I am hacking into NSA or something but they don't know I am just downloading the package lists by running sudo apt-get update. 😂

Don't tell them what you doing. You are not lying to them, it's their own thinking. At least now developers will get some respect in the society.

Just change terminal font color with green,, + F11 you will look like expert hacker for them,,

@faisalarkan21 haha yeah I already got it looking like in a Matrix.

I found a post on stack overflow a while back called "Make it look like I'm working". People started posting scripts that did nothing but printing a bunch of random stuff on the screen so it looks like you're hacking the Pentagon.
Trust me, people go nuts when they see some of that stuff on a green on black terminal
