In this recent post on Reddit.com, a developer asks the community about some of his feelings about bugs in his software and his focus on quality:

No one has told me this and I don't need them too. I feel like one bug that has a negative impact on the user experience is too many bugs. I've been programming for over 5 years professionally and I still introduce bugs into my code. [...] I don't like the expectation that I (and maybe others have) that my code must be perfect when I am not perfect. I don't like the fact that it only takes one mistake to affect so many people. [...] I'm wondering if others on here have every felt this way. What have you done about it?

Suggestions in the comments talk about everything from dealing with the apparent burnout the developer is facing, a reminder that no code is bug free and some recommendations of testing and bug tracking to help make the quality of the code better (and give visibility into the level of work being done).
