So this just happened. I was working on a project and I just found a weird directory named '~' in there. I am on Linux so I simply did an "rm -rf ~" :/

It was too late when I realized it deleted all my files in my home directory. All my projects and configuration files. The sad part was it did not delete that shitty random directory because permission denied. Thank God I got into the habit of making weekly backups of my system and Thank God I use git.
