Personal Ethics as a Computing Professional

I recently read the "ACM Code of Ethics and Professional Conduct," and I was struck by how much it seems that these are not followed by computing professionals. Granted, the majority of these professionals are not members of the ACM, but it seems that everyone should follow a basic code of ethics, regardless of membership in any organization. I think that the most important guideline to follow is that one should always try to contribute to society. Because there are so many people with such different skill sets, each person should contribute his expertise to benefit everyone as a whole. This could be, for example, identifying possible solutions to problems or planning an implementation. Personally, I find that contributing to or starting open source projects has been very beneficial to me in that I try to solve a problem as best I can while being exposed to the ideas of others.
