Hacker (programmer subculture)
A hacker is an adherent of the computer programmer subculture that originally emerged in academia in the 1960s, around the Massachusetts Institute of Technology (MIT)'s Tech Model Railroad Club (TMRC) and MIT Artificial Intelligence Laboratory. Hackers from this subculture tend to emphatically differentiate themselves from what they pejoratively call "crackers"; those who are generally referred to by media and members of the general public using the term "hacker", and whose primary focus, be it to malign or benevolent purposes, lies in exploiting weaknesses in computer security.
