How to commit jupyter notebooks without output to git while keeping the notebooks outputs intact locally

  1. Create a .gitattributes file inside the directory with the notebooks

A practical guide to prepare and take the PSM I (Professional Scrum Master 1) certification, from Scrum.org, entirely by yourself (no course required).

How to take the PSM I certification from Scrum.org entirely by yourself

Some people ask me about Scrum.org certifications: what to study, how to apply for the exam and advice for taking it. So I decided to write a guide for those interested in preparing and taking PSM I (Professional Scrum Master) without spending a fortune with training. With discipline, in around a month (or two), you should be ready to take the test.

The advice compiled here came from experienced agile coaches. Worked very well for me and I hope they will also help those who are seeking directions.
