Once upon a time, in a rabbit outsourcing warren of Bunnylore, there was a young software developer bunny. And as a developer, she has had one very unusual treat: she was obsessed with eliminating all the bugs she can get his forelegs on. So, it is not surprising that her friends called her a “No Bugs” Bunny (or simply “NoBugs”).
Later on, she grew up, so she decided that “Bunny” in her name has became inappropriate (not to mention potential arguments with Warner Brothers), so she has asked all her friends to call her “No Bugs” Bunny. She has made a career as a team lead and software architect, and they lived happily ever after.

Quote:
trying to optimize out a 3e-7 performance hit is very rarely worth the trouble.
Another Quote:
With 4S/4U boxes having typical MTBFs of 3–5 years, the next question we should ask ourselves, is “Hey, will we really be able to write software which crashes much more rarely than that?”
