I was trying to setup local postgres via docker, and wanted to see if my default user was created. I found out that there is more than one way to skin the cat.

Google expects credentials in a json file. Any file to be deployed to heroku must be in git. But credentials are sensitive info that should never be in git. So what do we do ?

How to troubleshoot this error?

Recently I did a couple of open source contributions. I decided to document my learning here.

In this pull request I fixed a bug for pre-commit project.
