General definition
Reflecting the two types of hackers, there are two definitions of the word "hacker":
# Originally, hacker simply meant advanced computer technology enthusiast (both hardware and software) and adherent of programming subculture; see
hacker culture
The hacker culture is a subculture of individuals who enjoy—often in collective effort—the intellectual challenge of creatively overcoming the limitations of software systems or electronic hardware (mostly digital electronics), to a ...

Today, mainstream usage of "hacker" mostly refers to computer criminals, due to the mass media usage of the word since the 1990s.
This includes what hacker slang calls "

s", people breaking into computers using programs written by others, with very little knowledge about the way they work. This usage has become so predominant that the general public is largely unaware that different meanings exist. While the self-designation of hobbyists as hackers is generally acknowledged and accepted by computer security hackers, people from the programming subculture consider the computer intrusion related usage incorrect, and emphasize the difference between the two by calling security breakers "crackers" (analogous to a

).
The controversy is usually based on the assertion that the term originally meant someone messing about with something in a positive sense, that is, using playful cleverness to achieve a goal. But then, it is supposed, the meaning of the term shifted over the decades and came to refer to computer criminals.
As the security-related usage has spread more widely, the original meaning has become less known. In popular usage and in the media, "computer intruders" or "computer criminals" is the exclusive meaning of the word today. (For example, "An Internet 'hacker' broke through state government security systems in March.") In the computer enthusiast (Hacker Culture) community, the primary meaning is a complimentary description for a particularly brilliant programmer or technical expert. (For example, "

's current usage of the term may be traced back to the early 1980s. When the term, previously used only among computer enthusiasts, was introduced to wider society by the mainstream media in 1983, even those in the computer community referred to computer intrusion as "hacking", although not as the exclusive definition of the word. In reaction to the increasing media use of the term exclusively with the criminal connotation, the computer community began to differentiate their terminology. Alternative terms such as "

" developed when laws against breaking into computers came into effect, to distinguish criminal activities from those activities which were legal.
Representation in network news
However, network news use of the term consistently pertained primarily to the criminal activities, despite the attempt by the technical community to preserve and distinguish the original meaning, so today the mainstream media and general public continue to describe computer criminals, with all levels of technical sophistication, as "hackers" and do not generally make use of the word in any of its non-criminal connotations. Members of the media sometimes seem unaware of the distinction, grouping legitimate "hackers" such as

and used negatively, including those who have historically preferred to self-identify as hackers. Many advocate using the more recent and nuanced alternate terms when describing criminals and others who negatively take advantage of security flaws in software and hardware. Others prefer to follow common popular usage, arguing that the positive form is confusing and unlikely to become widespread in the general public. A minority still use the term in both senses despite the controversy, leaving context to clarify (or leave ambiguous) which meaning is intended.
However, because the positive definition of hacker was widely used as the predominant form for many years before the negative definition was popularized, "hacker" can therefore be seen as a
shibboleth

, identifying those who use the technically-oriented sense (as opposed to the exclusively intrusion-oriented sense) as members of the computing community. On the other hand, due to the variety of industries software designers may find themselves in, many prefer not to be referred to as hackers because the word holds a negative denotation in many of those industries.
A possible middle ground position has been suggested, based on the observation that "hacking" describes a collection of skills and tools which are used by hackers of both descriptions for differing reasons. The analogy is made to

Overlaps and differences
The main basic difference between programmer subculture and computer security hacker is their mostly separate historical origin and development. However, the ''Jargon File'' reports that considerable overlap existed for the early phreaking at the beginning of the 1970s. An article from MIT's student paper ''The Tech'' used the term hacker in this context already in 1963 in its pejorative meaning for someone messing with the phone system.
[ The overlap quickly started to break when people joined in the activity who did it in a less responsible way. This was the case after the publication of an article exposing the activities of Draper and Engressia.
According to Raymond, hackers from the programmer subculture usually work openly and use their real name, while computer security hackers prefer secretive groups and identity-concealing aliases.] Also, their activities in practice are largely distinct. The former focus on creating new and improving existing infrastructure (especially the software environment they work with), while the latter primarily and strongly emphasize the general act of circumvention of security measures, with the effective use of the knowledge (which can be to report and help fixing the security bugs, or exploitation reasons) being only rather secondary. The most visible difference in these views was in the design of the MIT hackers' Incompatible Timesharing System
Incompatible Timesharing System (ITS) is a time-sharing operating system developed principally by the MIT Artificial Intelligence Laboratory, with help from Project MAC. The name is the jocular complement of the MIT Compatible Time-Sharing System ...
, which deliberately did not have any security measures.
There are some subtle overlaps, however, since basic knowledge about computer security is also common within the programmer subculture of hackers. For example, Ken Thompson noted during his 1983 Turing Award

". Furthermore, Thompson argued, the C compiler

itself could be modified to automatically generate the rogue code, to make detecting the modification even harder. Because the compiler is itself a program generated from a compiler, the Trojan horse could also be automatically installed in a new compiler program, without any detectable modification to the source of the new compiler. However, Thompson disassociated himself strictly from the computer security hackers: "I would like to criticize the press in its handling of the 'hackers,' the 414 gang, the Dalton gang, etc. The acts performed by these kids are vandalism at best and probably trespass and theft at worst. ... I have watched kids testifying before Congress. It is clear that they are completely unaware of the seriousness of their acts."
The programmer subculture of hackers sees secondary circumvention of security mechanisms as legitimate if it is done to get practical barriers out of the way for doing actual work. In special forms, that can even be an expression of playful cleverness. However, the systematic and primary engagement in such activities is not one of the actual interests of the programmer subculture of hackers and it does not have significance in its actual activities, either. A further difference is that, historically, members of the programmer subculture of hackers were working at academic institutions and used the computing environment there. In contrast, the prototypical computer security hacker had access exclusively to a home computer and a modem. However, since the mid-1990s, with home computers that could run Unix-like operating systems and with inexpensive internet home access being available for the first time, many people from outside of the academic world started to take part in the programmer subculture of hacking.
Since the mid-1980s, there are some overlaps in ideas and members with the computer security hacking community. The most prominent case is Robert T. Morris, who was a user of MIT-AI, yet wrote the Morris worm. The ''Jargon File'' hence calls him "a true hacker who blundered". Nevertheless, members of the programmer subculture have a tendency to look down on and disassociate from these overlaps. They commonly refer disparagingly to people in the computer security subculture as crackers and refuse to accept any definition of hacker that encompasses such activities. The computer security hacking subculture, on the other hand, tends not to distinguish between the two subcultures as harshly, acknowledging that they have much in common including many members, political and social goals, and a love of learning about technology. They restrict the use of the term cracker to their categories of script kiddie

es and various variants. The programmer subculture of hackers has stories about several hardware hacks in its folklore, such as a mysterious "magic" switch attached to a PDP-10 computer in MIT's AI lab that, when switched off, crashed the computer. The early hobbyist hackers built their home computers themselves from construction kits. However, all these activities have died out during the 1980s when the phone network switched to digitally controlled switchboards, causing network hacking to shift to dialing remote computers with modems when pre-assembled inexpensive home computers were available and when academic institutions started to give individual mass-produced workstation computers to scientists instead of using a central timesharing system. The only kind of widespread hardware modification nowadays is case modding
