I downloaded a small widget for monitoring my bandwidth quota from my ISP on Ubuntu and it wasn’t working.
Since I got it from GitHub I decided to crack it open and see if I could fix it.
After a little poking around I made what I thought would be the correct changes and verified that it now worked as expected.
Then I took the plunge and sent an unsolicited Pull Request with my fix and it was accepted 
Pretty pleased with myself right now!
It was only a three line fix, but I’m happy because I knew which screw to turn
i hope i make my first pull request soon
