  12. /34@yegor256 12 “A good programmer will produce fault-free code, while a bad programmer will produce code that is fault- ridden.” Good Coder = Less BugsWrong!
  13. /34@yegor256 13 “Some people mistakenly refer to software defects as bugs. When called bugs, they seem like pesky things that should be swatted or even ignored. This trivializes a critical problem and fosters a wrong attitude. Thus, when an engineer says there are only a few bugs left in a program, the reaction is one of relief. Suppose, however, that we called them time bombs instead of bugs. Would you feel the same sense of relief if a programmer told you that he had thoroughly tested a program and there were only a few time bombs left in it? Just using a different term changes your attitude entirely.” Bug = Time BombWrong!

  15. /34@yegor256 15 “If you’re scared of making changes, you can’t make something dramatically better, or do that big code cleanup. Maybe you can’t even deploy the code that you already wrote and tested, because it feels too scary. You just want to stick what’s sort-of-working, even if it’s not great.” “Fear makes you a worse programmer” Julia Evans,
