(I) Logging

Purpose

Logging is not glamorous and it is not cool. But it is an absolutely essential part of building a system that will scale big time. It is fundamentally different from putting a lot of print statements in your code.

Do this

• Read: How to save hours of debugging with logs
• Read: Log Everything All The Time
• Implement a few logging statements in your actual nanotwitter (each student on the team does their own)

Please submit this

Please think about and answer these questions:

1. In what ways is actual logging (using any of the tools around, for example Papertrail) better than putting simple print statements in your code? Or is it no different?

2. Show the lines of code you added to nanoTwitter to do some logging (each student on the team should do their own.)
