And instead of saying "You're free to use it in any way with no strings attached and no guarantee of fitness/correctness", it would be better include a proper source code license file with your code.
@slayemin: Here's some licenses that you might want:
Suggestion for "free to do whatever": MIT license
Suggestion for "free to do whatever but give me credit and share changes": LGPL
Suggestion for "I don't care at all, just use the code if you want!": Public domain ((this isn't actually a license) This only works for countries that have public domain, and you can just ignore the countries that don't - people in those countries will use it anyway and it becomes their problem)
