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.

Professional certification
Professional certification, trade certification, or professional designation, often called simply certification or qualification, is a designation earned by a person to assure qualification to perform a job or task. Not all certifications that use post-nominal letters are an acknowledgement of educational achievement, or an agency appointed to safeguard the public interest.

Punched card
A punched card, punch card, IBM card, or Hollerith card is a piece of stiff paper that contains digital information represented by the presence or absence of holes in predefined positions. Now an obsolete recording medium, punched cards were widely used throughout the 19th century for controlling textile looms and in the late 19th and early 20th century for operating fairground organs and related instruments. They were used through the 20th century in unit record machines for input, processing, and data storage. Early digital computers used punched cards, often prepared using keypunch machines, as the primary medium for input of both computer programs and data. Some voting machines use punched cards. punched card of the type most widely used in the 20th century. Card size was 7⁄8 in × 3⁄4 in (187.325 mm × 82.55 mm). This example displays the 1964 EBCDIC character set, which added more special characters to earlier encodings. ]] (source: http://en.wikipedia.org/wiki/Punched_card)
Early adopter
An early adopter or lighthouse customer is an early customer of a given company, product, or technology; in politics, fashion, art, and other fields, this person would be referred to as a trendsetter.
