Why would you fear 'failure' putting up code for people to look at (and maybe run) for free in case it helps them? (Put a good MIT/BSD/Apache/etc licence on your code and you are not legally liable for anything idiotic they do with it.) Are you worried about being laughed at? Being embarrassed at some future interview/meeting? If you do stuff for the right reasons (and follow the law, etc) then anyone laughing at you is someone you don't want to work with.
