Hacker (programmer subculture) in the context of "Electronic hardware"

Hacktivism (or hactivism; a portmanteau of hack and activism) is the use of computer-based techniques such as hacking as a form of civil disobedience to promote a political agenda or social change. A form of Internet activism with roots in hacker culture and hacker ethics, its ends are often related to free speech, human rights, or freedom of information movements.

Hacktivist activities span many political ideals and issues. Hyphanet, a peer-to-peer platform for censorship-resistant communication, is a prime example of translating political thought and freedom of speech into code. Hacking as a form of activism can be carried out by a singular activist or through a network of activists, such as Anonymous and WikiLeaks, working in collaboration toward common goals without an overarching authority figure. For context, according to a statement by the U.S. Justice Department, Julian Assange, the founder of WikiLeaks, plotted with hackers connected to the "Anonymous" and "LulzSec" groups, who have been linked to multiple cyberattacks worldwide. In 2012, Assange, who was being held in the United Kingdom on a request for extradition from the United States, gave the head of LulzSec a list of targets to hack and informed him that the most significant leaks of compromised material would come from the National Security Agency, the Central Intelligence Agency, or the New York Times.

The Linux Documentation Project (LDP) is a dormant all-volunteer project that maintains a large collection of GNU and Linux-related documentation and publishes the collection online. It began as a way for hackers to share their documentation with each other and with their users, and for users to share documentation with each other. Its documents tend to be oriented towards experienced users such as professional system administrators, but it also contains tutorials for beginners.

A security hacker or security researcher is someone who explores methods for breaching or bypassing defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, sabotage, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.

Longstanding controversy surrounds the meaning of the term "hacker". In this controversy, computer programmers reclaim the term hacker, arguing that it refers simply to someone with an advanced understanding of computers and computer networks, and that cracker is the more appropriate term for those who break into computers, whether computer criminals (black hats) or computer security experts (white hats). A 2014 article noted that "the black-hat meaning still prevails among the general public". The subculture that has evolved around hackers is often referred to as the "computer underground".

The free software movement is a social movement with the goal of obtaining and guaranteeing certain freedoms for software users, namely the freedoms to run, study, modify, and share copies of software. Software which meets these requirements, The Four Essential Freedoms of Free Software, is termed free software.

Although drawing on traditions and philosophies among members of the 1970s hacker culture and academia, Richard Stallman formally founded the movement in 1983 by launching the GNU Project. Stallman later established the Free Software Foundation in 1985 to support the movement.
