Most of my personal code is my sites’ code or tools that I use to develop my sites. Anyone can unminify this code and read if they really want.
#I can use GitHub and Travis CI and any other open source tool for free
I like GitHub and I don’t like Bitbucket (they have free private repositories). I like to store all my code in the same place — it’s convenient. I also like Travis CI and use it for all my projects, even for my blog.
My future coworker may find it and may judge my coding skills by this code. I don’t want him to look into a wrong project so I try to make all my public code good. Later me will thank current me for that.
Often someone asks how I do this or that. If this or that is open sourced I could send a link to a file on GitHub. I can even select particular lines in that file.
