When talking to people and in documents, I prefer to summarize my specific interest in computing and collaborating with others online and software development under one term: hacking.
From Eric S. Raymond's How To Become A Hacker:
There is a community, a shared culture, of expert programmers and networking wizards that... originated the term ‘hacker’. Hackers built the Internet. Hackers made the Unix operating system what it is today. Hackers make the World Wide Web work. If you are part of this culture, if you have contributed to it and other people in it know who you are and call you a hacker, you're a hacker....
Hackers solve problems and build things, and they believe in freedom and voluntary mutual help.
From this definition, I definitely feel that I belong in this group and am in line with a hacker's values and goals.
However, I do not know how to briefly explain the difference between the popular definition of hacking (to break into computer systems) and the hackers' "correct" definition.
Are there any alternative terms I could use in a resume or other document where I can only make such a remark about my interests and hobbies very briefly?
I read the question "Has “hacker” definitely gained a negative connotation?" but it does not suggest any alternative terms beside "ethical hacker," which means someone who ethically breaks into computer systems.
