The programmer subculture of hackers
The computer security use is contrasted by the different understanding of hacker as a person who follows a spirit of playful cleverness and loves programming. It is found in an originally academic movement unrelated to computer security and most visibly associated with free software and open source. It also has a hacker ethic, based on the idea that writing software and sharing the result on a voluntary basis is a good idea, and that information should be free, but that it's not up to the hacker to make it free by breaking into private computer systems. Academic hackers disassociate from the mass media's pejorative use of the word 'hacker' referring to computer security, and usually prefer the term 'cracker' for that meaning.
In this hacker culture, a computer hacker is a person who enjoys designing software and building programs with a sense for aesthetics and playful cleverness. The term hack in this sense can be traced back to "describe the elaborate college pranks that...students would regularly devise" (Levy, 1984 p.10). To be considered a 'hack' was an honour among like-minded peers as "to qualify as a hack, the feat must be imbued with innovation, style and technical virtuosity" (levy, 1984 p.10)
According to Eric S. Raymond,[21] the Open source and Free Software hacker subculture developed in the 1960s among ‘academic hackers’[22] working on early minicomputers in computer science environments in the United States. After 1969 it fused with the technical culture of the pioneers of the Arpanet. The PDP-10 machine AI at MIT, which was running the ITS operating system and was connected to the Arpanet, provided an early hacker meeting point. After 1980 the subculture coalesced with the culture of Unix, and after 1987 with elements of the early microcomputer hobbyists that themselves had connections to radio amateurs in the 1920s. Since the mid-1990s, it has been largely coincident with what is now called the free software and open source movement.
Many programmers have been labeled "great hackers,"[23] but the specifics of who that label applies to is a matter of opinion. Certainly major contributors to computer science such as Edsger Dijkstra and Donald Knuth, as well as the inventors of popular software such as Linus Torvalds (Linux), and Dennis Ritchie and Ken Thompson (the C programming language) are likely to be included in any such list; see also List of programmers. People primarily known for their contributions to the consciousness of the academic hacker culture include Richard Stallman, the founder of the free software movement and the GNU project, president of the Free Software Foundation and author of the famous Emacs text editor as well as the GNU Compiler Collection (GCC), and Eric S. Raymond, one of the founders of the Open Source Initiative and writer of the famous text The Cathedral and the Bazaar and many other essays, maintainer of the Jargon File (which was previously maintained by Guy L. Steele, Jr.).
Within the academic hacker culture, the term hacker is also used for a programmer who reaches a goal by employing a series of modifications to extend existing code or resources. In this sense, it can have a negative connotation of using kludges to accomplish programming tasks that are ugly, inelegant, and inefficient. This derogatory form of the noun "hack" is even used among users of the positive sense of "hacker" (some argue that it should not be, due to this negative meaning; others argue that some kludges can, for all their ugliness and imperfection, still have "hack value"). In a very universal sense, hacker also means someone who makes things work beyond perceived limits in a clever way in general.[4] That is, people who apply the creative attitude of software hackers in fields other than computing. This includes even activities that predate computer hacking, for example reality hackers.[24] More recent examples of this usage are wetware hackers and media hackers. According to the Jargon File the word hacker was used in a similar meaning among radio amateurs already in the 1950s.[25]
The culture sometimes uses jargon which is "incomprehensible to outsiders".[26] Examples are 'losing' "when a piece of equipment is not working"[26] and 'munged' "when a piece of equipment is ruined".[26]
