Stephen Wolfram (born 29 August 1959) is a British scientist^[1] and the chief designer of the Mathematica software application and the Wolfram Alpha computational knowledge engine.

Biography[link]

Stephen Wolfram's parents were Jewish refugees who emigrated from Westphalia, Germany, to England in 1933.^[2][3] Wolfram's father Hugo was a textile manufacturer and novelist (Into a Neutral Country) and his mother Sybil was a professor of philosophy at the University of Oxford.^[4] He has a younger brother, Conrad.^[5]

Wolfram was educated at Eton, where he amazed and frustrated teachers by his brilliance and refusal to be taught, instead doing other students' math homework for money.^[4] Wolfram published an article on particle physics^[6] but claimed to be bored and left Eton prematurely in 1976.^[7] He entered St John's College, Oxford at age 17 but found lectures "awful".^[4] Working independently, Wolfram published a widely cited paper on heavy quark production at age 18^[3] and nine other papers^[4] before leaving in 1978 without graduating.^[7] He received a Ph.D. in particle physics from the California Institute of Technology at age 20,^[8] joined the faculty there and received one of the first MacArthur awards in 1981, at age 21.^[7] According to Google Scholar Stephen Wolfram is cited by over 30,000 publications (up to April 2012) and has an h-index of 58. ^[9]

Wolfram's work with Geoffrey Fox on the theory of the strong interaction is still used today in experimental particle physics.^[10] Wolfram is married to a mathematician and has four children.^[11]

Wolfram received a standing ovation^[12] for his 2010 TED Talk, Computing the theory of everything^[13], as well as his 2012 talk at SXSW, where he was named Speaker of the Event^[14].

Work[link]

Symbolic Manipulation Program[link]

Wolfram led the development of the computer algebra system SMP (Symbolic Manipulation Program) in the Caltech physics department during 1979–1981. A dispute with the administration over the intellectual property rights regarding SMP—patents, copyright, and faculty involvement in commercial ventures—eventually caused him to resign from Caltech.^[15] SMP was further developed and marketed commercially by Inference Corp. of Los Angeles during 1983–1988.

Complex systems and cellular automata[link]

In 1983, Wolfram left for the School of Natural Sciences of the Institute for Advanced Study in Princeton, where he studied cellular automata, mainly with computer simulations. He produced a series of papers systematically investigating the class of elementary cellular automata, conceiving the Wolfram code, a naming system for one-dimensional cellular automata, and a classification scheme for the complexity of their behavior. He conjectured that the Rule 110 cellular automaton may be Turing complete. In the middle 1980s Wolfram worked on simulations of physical processes (such as turbulent fluid flow) with cellular automata on the Connection Machine alongside Richard Feynman.^[16] and helped ignite the field of complex systems founding the first institute devoted to this subject, The Center for Complex Systems Research (CCSR) at the University of Illinois at Urbana-Champaign^[17] and the journal Complex Systems in 1987.^[18]

Mathematica[link]

In 1986 Wolfram left the Institute for Advanced Study for the University of Illinois at Urbana-Champaign where he founded their Center for Complex Systems Research and started to develop the computer algebra system Mathematica, which was first released in 1988, when he left academia. In 1987 he co-founded a company called Wolfram Research which continues to develop and market the program.^[3]

[edit] A New Kind of Science

From 1992 to 2002, he worked on his controversial book A New Kind of Science, which presents an empirical study of very simple computational systems. Additionally, it argues that for fundamental reasons these types of systems, rather than traditional mathematics, are needed to model and understand complexity in nature. Wolfram's conclusion is that the universe is digital in its nature, and runs on fundamental laws which can be described as simple programs. He predicts a realization of this within the scientific communities will have a major and revolutionary influence on physics, chemistry and biology and the majority of the scientific areas in general, which is the reason for the book's title.

Since the release of the book in 2002, Wolfram has split his time between developing Mathematica and encouraging people to get involved with the subject matter of A New Kind of Science by giving talks, holding conferences, and starting a summer school devoted to the topic.^[19]

Computational knowledge engine[link]

In March 2009, Wolfram announced Wolfram|Alpha, an answer engine with a new approach to knowledge extraction and an easy-to-use interface, launched on May 16, 2009 ^[20][21] and a Pro version launched on February 8, 2012^[22] The engine is based on natural language processing, a large library of algorithms and answers queries using the approach described in A New Kind of Science. The application programming interface (API) allows other applications to extend and enhance Alpha.^[23] Wolfram|Alpha is the answer engine behind Microsoft's Bing^[24] and Apple's Siri (along with Google and Yelp!) answering factual questions.^[25]

Martin Bryant (born 7 May 1967) is an Australian spree killer who was convicted of murdering 35 people and injuring 21 others in the Port Arthur massacre, a shooting spree in Port Arthur, Tasmania, Australia, in 1996.^[1] He is currently serving 35 life sentences plus 1,035 years without parole in the psychiatric wing of Risdon Prison in Hobart, Tasmania.^[2] His rampage ranks among the deadliest of the 20th century.

Early life[link]

Childhood[link]

Martin Bryant was born in Tasmania, Australia, the first son born to Maurice and Carleen Bryant. His father was an English immigrant from Dunston,^[3] Tyne and Wear in North East England. Although the family home was in Lenah Valley, Tasmania, Bryant spent some of his childhood at their beach home in Carnarvon Bay, Tasmania. In a 2011 interview his mother recalls that she would often find his toys broken at a very young age, branding him an "annoying" and "different" child . A psychologist's view was that he would never hold down a job as he would aggravate people to such an extent that he'd always be in trouble.^[4] Other cases that locals can recall include that he once pulled the snorkel from another boy while diving, and cut down trees on a neighbour's property. He was described by teachers as being distant from reality and unemotional. At school he was a disruptive and sometimes violent child, and suffered severe bullying by other children. After he was suspended from New Town Primary School in 1977, psychological assessments of Bryant note his torturing of animals. He returned to school the following year with improved behaviour; however, he persisted in teasing younger children. He was transferred to a special education unit at New Town High School in 1980 where he deteriorated both academically and in behaviour throughout his remaining school years.^[5]

Descriptions of Bryant's behaviour as an adolescent show that he continued to be disturbed. He was revealed to have an I.Q. of 66,^[6] equivalent to an 11-year-old and in the bottom 1.17 percent of the Australian population, and was possibly autistic.^[5] Further testing following his arrest indicated a verbal I.Q. of 64 and non-verbal reasoning and cognitive functioning of 68, giving a full scale I.Q. of 66, an age equivalent of 11 years in the 10th percentile (90% of 11 year olds would score higher). On leaving school he was assessed for a disability pension by a psychiatrist who wrote: "Cannot read or write. Does a bit of gardening and watches TV ... Only his parents' efforts prevent further deterioration. Could be schizophrenic and parents face a bleak future with him." Bryant received a disability pension, though he also worked as a handyman and gardener.^[7]

Adulthood[link]

In early 1987 when Bryant was 19, he met then 54-year-old eccentric recluse Helen Mary Elizabeth Harvey, heiress to a share in the Tattersall's lottery fortune, while looking for new customers for his lawn-mowing service. Harvey, who lived with her mother Hilva, befriended Bryant who became a regular visitor to her neglected New Town mansion, and assisted with tasks such as feeding the fourteen dogs living inside the house, and the forty cats living inside her garage.^[7] In June 1990, someone reported Harvey to the health authorities, and medics found both Harvey and her mother in need of urgent hospital treatment. Seventy-nine-year-old Hilza Harvey died several weeks later.^[8] A clean-up order was placed on the mansion and Bryant's father took long service leave to assist in cleaning the interior. Harvey now invited Bryant to live with her in the mansion and they began spending large amounts of money, which included the purchase of more than 30 new cars in less than three years. The couple began to spend most days shopping, usually after having lunch in a local restaurant. Around this time Bryant was reassessed for his pension, and a note was attached to the paperwork "Father protects him from any occasion which might upset him as he continually threatens violence ... Martin tells me he would like to go around shooting people. It would be unsafe to allow Martin out of his parents' control".^[7]

In 1991, as a result of no longer being allowed to have animals at the house, Harvey and Bryant moved together onto a 29 hectares (72 acres) farm called Taurusville that she had purchased in Copping, Tasmania. Neighbours recalled he always carried an air gun and often fired it at tourists as they stopped to buy apples at a stall on the highway, and that late at night he would roam through the surrounding properties firing the gun at dogs when they barked at him. They avoided him "at all costs" despite his attempts to befriend them.^[7]

On 20 October 1992 Harvey was killed when her car veered to the wrong side of the road and hit an oncoming car directly.^[7] Bryant was inside the vehicle at the time of the accident, and was hospitalised for seven months with severe neck and back injuries. He was briefly investigated by police for the role he played in the accident, as Bryant had a habit of lunging for the steering wheel and Harvey had already had three accidents as a result. She often told people that this was the reason she never drove faster than 60 kilometres an hour (37 mph). Bryant was named the sole beneficiary of Harvey's will and came into possession of assets totalling more than $550,000. As Bryant had only the "vaguest notions" of financial matters, his mother subsequently applied for and was granted a guardianship order, placing Bryant's assets under the management of Public Trustees. The order was based on evidence of Bryant's diminished intellectual capacity.^[7]

After Harvey's death, Bryant's father Maurice moved into the Copping farm to look after it. Bryant returned to the farm after leaving hospital the following year. He had been prescribed antidepressants, and had secretly transferred his joint bank account and utilities into his wife's name.^[7] Two months later, on 14 August, a person visiting Maurice Bryant found a note saying "call the police" pinned to the door and found several thousand dollars in his car. Police searched the property for Maurice Bryant, without success. Divers were called to search the four dams on the property. On 16 August his body was found in the dam closest to the farmhouse with one of Martin Bryant's diving weight belts around his neck. Although ruled a suicide by drowning, police described it as an "unnatural" death. Bryant inherited the proceeds of his father's superannuation fund valued at $250,000.

Bryant sold the Copping farm for $143,000 and kept the Hobart mansion.^[5] While living at Copping, the white overalls he habitually wore were replaced with clothing more in line with Harvey's financial status. Now that he was alone his dress became more bizarre. He often wore a grey linen suit, cravat, lizard skin shoes and Panama hat while carrying a briefcase during the day, telling anyone who listened that he had a well-paying career. He often wore an electric blue suit with flared trousers and a ruffled shirt to the restaurant he regularly used. The restaurant owner recalled: "It was horrible. Everyone was laughing at him, even the customers. I really felt suddenly quite sorry for him. I realised this guy didn't really have any friends."

With Harvey and his father dead Bryant became increasingly lonely. From 1993 to late 1995, he visited various overseas countries 14 times and a summary of his domestic airline travel filled three pages. He hated the destinations he travelled to, as he found that people there avoided him just as they did in Tasmania. However he enjoyed the flights, as he could speak to the people sitting adjacent to him who had no choice but to be polite. Bryant later took great joy in describing some of the more successful conversations he had with fellow passengers. In late 1995, he became suicidal after deciding he had "had enough": "I just felt more people were against me. When I tried to be friendly toward them, they just walked away". Although he had previously been little more than a social drinker, his alcohol consumption increased and, although he had not had a drink on that day, had especially escalated in the six months prior to the massacre. Bryant's average daily consumption was estimated at half a bottle of Sambuca and a bottle of Baileys Irish Cream supplemented with Port wine and other sweet alcoholic drinks.^[5] According to Bryant, he thought the plan for Port Arthur may have first occurred to him four to twelve weeks before the event.^[5]

Port Arthur massacre[link]

Bryant has provided conflicting and confused accounts of what led him to kill 35 people at the Port Arthur site on 28 April 1996. It appears his desire for attention, as he allegedly told a next door neighbour "I'll do something that will make everyone remember me," as well as mounting frustration at his social isolation had made him unbearably angry.

His first victims, David and Sally Martin, owned the bed and breakfast guest house "Seascape." The Martins had bought the B & B that Bryant's father had wanted to buy and he often complained to his son about this. Bryant apparently believed the Martins had deliberately bought the property to hurt his family and blamed the Martins for the depression that led to his father's death.^[5] He shot them in that guest house before traveling to the Port Arthur ruins. Bryant entered The Broad Arrow Café on the historical site's grounds, carrying a large blue duffel bag. Upon sitting down to eat a meal in the front balcony area, he remarked "There's a lot of wasps about today"^[9] to no one in particular. Once he finished, Bryant moved towards the back of the café and set a video camera on a vacant table. He took out an AR-15 semi-automatic rifle and, firing from the hip, began shooting patrons and staff. Within 15 seconds, he had fired 17 shots killing 12 people and wounded 10. Bryant then walked to the other side of the shop and fired 12 more times killing another eight people while wounding five. He then changed magazines before fleeing, shooting at people in the car park and from his yellow Volvo sedan as he drove away. Bryant drove three hundred metres down the road, to where a woman and her two children were walking. He stopped and fired two shots killing the woman and the child she was carrying. The older child fled, but Bryant followed her and killed her with a single shot. He then stole a gold-coloured BMW by killing the occupants. A short distance down the road he stopped beside a couple in a white Toyota and, drawing his weapon, ordered the male occupant into the boot of the BMW. After shutting the boot he fired two shots into the windscreen of the Toyota, killing the female driver. He returned to the guest house, set the stolen car alight and took his hostage inside with the Martins' corpses. The police soon arrived and tried to negotiate with Bryant for many hours before the battery in the phone he was using died, ending communication. Bryant's only demand was to be transported in an army helicopter to an airport. Sometime during the negotiations, Bryant killed his hostage.

The next morning, 18 hours later, Bryant set fire to the guest house and attempted to escape in the confusion. Suffering burns to his back and buttocks, he was captured and taken to Royal Hobart Hospital where he was treated and kept under heavy guard.

Imprisonment[link]

Bryant was judged as fit to stand trial, and his trial was scheduled to begin 7 November 1996. Bryant initially pleaded not guilty, but was persuaded by his court-appointed lawyer and the prosecution to plead guilty to all charges.^[6]

Two weeks later, Hobart Supreme Court Judge William Cox gave Bryant 35 life sentences for the murders plus 1035 years for other crimes, and ordered that he should remain in prison for the "rest of his life."^[10]

He has attempted suicide six times while being imprisoned.^[11] For the first eight months of his imprisonment, he was held in a purpose-built special suicide prevention cell, in almost complete solitary confinement. He remained in protective custody for his own safety, until he was moved to a newly built detention centre ten years after his conviction.

On 13 November 2006 Bryant was moved into Hobart's Wilfred Lopes Centre,^[2] a secure mental health unit run by the Tasmanian Department of Health and Human Services. The 35-bed unit for inmates with serious mental illness is staffed with doctors, nurses and other support workers. Inmates are not locked down and can come and go from their cells. Exterior security at the facility is provided by a three-wall perimeter patrolled by private contract guards.^[12]

Bryant attempted suicide on 25 March 2007 by slashing his wrist with a razor blade. On 27 March he cut his throat with another razor blade and was hospitalised briefly.^[13]

Media coverage[link]

Newspaper coverage immediately after the massacre raised serious questions about journalistic practices. Photographs of Martin Bryant had the eyes digitally manipulated with the effect of making Bryant appear deranged. Despite criticism, the manipulated photographs continue to be used in media reporting a decade later. There were also questions as to how the photographs had been obtained. The Tasmanian Director of Public Prosecutions warned the media that the reporting compromised a fair trial and writs were issued against the Hobart Mercury (which used Bryant's picture under the headline “This is the man”), The Australian, The Age and the Australian Broadcasting Corporation over their coverage. The chairman of the Australian Press Council at the time, David Flint, argued that because Australian newspapers regularly ignored contempt-of-court provisions, this showed that the law, not the newspapers, needed change. Flint suggested that such a change in the law would not necessarily lead to trial by media.^[14]

Political aftermath[link]

As a response to the spree killing, Australian State and Territory governments placed tight restrictions on semi-automatic centre-fire rifles, high-capacity repeating shotguns and high-capacity rifle magazines. In addition to this, heavy limitations were also put into place on low-capacity repeating shotguns and rim-fire semi-automatic rifles. The Tasmanian state government attempted to ignore this directive but was threatened with a number of penalties from the federal government.^{[citation needed]} Though this resulted in stirring controversy, opposition to the new laws was overcome by media reporting of the massacre and mounting public opinion in the wake of the shootings (see Gun politics in Australia for more information on the 1996 legislation).

Richard Matthew Stallman (born 16 March 1953), often shortened to rms,^[1] is an American software freedom activist and computer programmer. In September 1983, he launched the GNU Project^[2] to create a free Unix-like operating system, and he has been the project's lead architect and organizer. With the launch of the GNU Project, he initiated the free software movement; in October 1985^[3] he founded the Free Software Foundation.

Stallman pioneered the concept of copyleft, and he is the main author of several copyleft licenses including the GNU General Public License, the most widely used free software license.^[4] Since the mid-1990s, Stallman has spent most of his time advocating for free software, as well as campaigning against software patents, digital rights management, and what he sees as excessive extension of copyright laws. Stallman has also developed a number of pieces of widely used software, including the original Emacs,^[5] the GNU Compiler Collection,^[6] the GNU Debugger,^[7] and various tools in the GNU coreutils.^[8] He co-founded the League for Programming Freedom in 1989.

Early years[link]

Stallman was born to Daniel Stallman and Alice Lippman,^[9] in 1953 in New York City. His first experience with computers was at the IBM New York Scientific Center when he was in high school. He was hired for the summer to write a numerical analysis program in Fortran. He completed the task after a couple of weeks and spent the rest of the summer writing a text editor in APL.^[10] Stallman spent the summer after his high-school graduation writing another program, a preprocessor for the PL/I programming language on the IBM System/360.^{[citation needed]}

During this time, Stallman was also a volunteer laboratory assistant in the biology department at Rockefeller University. Although he was already moving toward a career in mathematics or physics, his teaching professor at Rockefeller thought he would have a future as a biologist.^[11]

As a first-year student at Harvard University, Stallman was known for his strong performance in Math 55.^{[citation needed]} In 1971 he became a programmer at the MIT Artificial Intelligence Laboratory, and became a regular in the hacker community, where he was usually known by his initials, rms (which was the name of his computer accounts). In the first edition of the Hacker's Dictionary, he wrote "'Richard Stallman' is just my mundane name; you can call me 'rms'."^[1] Stallman graduated from Harvard magna cum laude earning a BA in Physics in 1974.^[12]

Stallman enrolled as a graduate student at MIT, but then ended his pursuit of a doctorate in physics to focus on his programming at the MIT AI Laboratory.

While a graduate student at MIT, Stallman published a paper with Gerald Jay Sussman on an AI truth maintenance system, called dependency-directed backtracking.^[13] This paper was an early work on the problem of intelligent backtracking in constraint satisfaction problems. As of 2003, the technique Stallman and Sussman introduced is still the most general and powerful form of intelligent backtracking.^[14] The technique of constraint recording, wherein partial results of a search are recorded for later reuse, was also introduced in this paper.^[14]

As a hacker in MIT's AI laboratory, Stallman worked on software projects like TECO, Emacs, and the Lisp machine Operating System. He would become an ardent critic of restricted computer access in the lab, which at that time was funded primarily by the Defense Advanced Research Projects Agency. When MIT's Laboratory for Computer Science (LCS) installed a password control system in 1977, Stallman found a way to decrypt the passwords and sent users messages containing their decoded password, with a suggestion to change it to the empty string (that is, no password) instead, to re-enable anonymous access to the systems. Around 20% of the users followed his advice at the time, although passwords ultimately prevailed. Stallman boasted of the success of his campaign for many years afterward.^[15]

Decline of MIT's hacker culture[link]

In the late 1970s and early 1980s, the hacker culture that Stallman thrived on began to fragment. To prevent software from being used on their competitors' computers, most manufacturers stopped distributing source code and began using copyright and restrictive software licenses to limit or prohibit copying and redistribution. Such proprietary software had existed before, and it became apparent that it would become the norm. This shift in the legal characteristics of software can be regarded as a consequence triggered by the U.S. Copyright Act of 1976, as stated by Stallman's MIT fellow Brewster Kahle.^[16]

When Brian Reid in 1979 placed time bombs in the Scribe markup language and word processing system to restrict unlicensed access to the software, Stallman proclaimed it "a crime against humanity."^[17] He clarified, years later, that it is blocking the user's freedom that he believes is a crime, not the issue of charging for the software.^[18]

In 1980, Stallman and some other hackers at the AI Lab were refused access to the source code for the software of a newly-installed laser printer, the Xerox 9700. Stallman had modified the software for the Lab's previous laser printer (the XGP, Xerographic Printer), so it electronically messaged a user when the person's job was printed, and would message all logged-in users waiting for print jobs if the printer was jammed. Not being able to add these features to the new printer was a major inconvenience, as the printer was on a different floor from most of the users. This experience convinced Stallman of people's need to be free to modify the software they use.^[19]

Richard Greenblatt, a fellow AI Lab hacker, founded Lisp Machines, Inc. (LMI) to market Lisp machines, which he and Tom Knight designed at the lab. Greenblatt rejected outside investment, believing that the proceeds from the construction and sale of a few machines could be profitably reinvested in the growth of the company. In contrast, the other hackers felt that the venture capital-funded approach was better. As no agreement could be reached, hackers from the latter camp founded Symbolics, with the aid of Russ Noftsker, an AI Lab administrator. Symbolics recruited most of the remaining hackers including notable hacker Bill Gosper, who then left the AI Lab. Symbolics forced Greenblatt to also resign by citing MIT policies. While both companies delivered proprietary software, Stallman believed that LMI, unlike Symbolics, had tried to avoid hurting the lab's community. For two years, from 1982 to the end of 1983, Stallman worked by himself to clone the output of the Symbolics programmers, with the aim of preventing them from gaining a monopoly on the lab's computers.^[20]

Stallman argues that software users should have the freedom to share with their neighbor and to be able to study and make changes to the software that they use. He maintains that attempts by proprietary software vendors to prohibit these acts are antisocial and unethical.^[21] The phrase "software wants to be free" is often incorrectly attributed to him, and Stallman argues that this is a misstatement of his philosophy.^[22] He argues that freedom is vital for the sake of users and society as a moral value, and not merely for pragmatic reasons such as possibly developing technically superior software.

In February 1984, Stallman quit his job at MIT to work full-time on the GNU project, which he had announced in September 1983.

GNU project[link]

Stallman announced the plan for the GNU operating system in September 1983 on several ARPANET mailing lists and USENET.^[23]

In 1985, Stallman published the GNU Manifesto, which outlined his motivation for creating a free operating system called GNU, which would be compatible with Unix. The name GNU is a recursive acronym for "GNU's Not Unix." Soon after, he started a non-profit corporation called the Free Software Foundation to employ free software programmers and provide a legal infrastructure for the free software movement. Stallman is the nonsalaried president of the FSF, which is a 501(c)(3) non-profit organization founded in Massachusetts.^[24] Stallman popularized the concept of copyleft, a legal mechanism to protect the modification and redistribution rights for free software. It was first implemented in the GNU Emacs General Public License, and in 1989 the first program-independent GNU General Public License (GPL) was released. By then, much of the GNU system had been completed. Stallman was responsible for contributing many necessary tools, including a text editor (Emacs), compiler (GCC), debugger (gdb), and a build automator (gmake). The notable exception was a kernel. In 1990, members of the GNU project began a kernel called GNU Hurd, which has yet to achieve the maturity level required for widespread usage.

In 1991, Linus Torvalds, a Finnish student, used the GNU development tools to produce the Linux kernel. The existing programs from the GNU project were readily ported to run on the resultant platform; most sources use the name Linux to refer to the general-purpose operating system thus formed. This has been a longstanding naming controversy in the free software community. Stallman argues that not using GNU in the name of the operating system unfairly disparages the value of the GNU project and harms the sustainability of the free software movement by breaking the link between the software and the free software philosophy of the GNU project.

Cover picture for O'Reilly Media's book Free as in Freedom

Stallman's influences on hacker culture include the name POSIX^[25] and the Emacs editor. On UNIX systems, GNU Emacs's popularity rivaled that of another editor vi, spawning an editor war. Stallman's take on this was to canonize himself as St. IGNUcius of the Church of Emacs^[26][27] and acknowledge that "vi vi vi is the editor of the beast," while "using a free version of vi is not a sin; it is a penance".^[28]

Around 1992, developers at Lucid Inc. doing their own work on Emacs clashed with Stallman and ultimately forked the software into what would become XEmacs.^[29] Technology journalist Andrew Leonard has characterized what he sees as Stallman's uncompromising stubbornness as common among elite computer programmers:

There's something comforting about Stallman's intransigence. Win or lose, Stallman will never give up. He'll be the stubbornest mule on the farm until the day he dies. Call it fixity of purpose, or just plain cussedness, his single-minded commitment and brutal honesty are refreshing in a world of spin-meisters and multimillion-dollar marketing campaigns.

—Andrew Leonard, Salon.com^[30]

Activism[link]

Richard Stallman giving a speech on "Free Software and your freedom" at the biennale du design of Saint Etienne (2008)

Stallman has written many essays on software freedom and since the early 1990s has been an outspoken political campaigner for the free software movement. The speeches he has regularly given are titled The GNU project and the Free Software movement,^[31] The Dangers of Software Patents,^[32] and Copyright and Community in the age of computer networks.^[33] In 2006 and 2007, during the eighteen month public consultation for the drafting of version 3 of the GNU General Public License, he added a fourth topic explaining the proposed changes.^[34]

Linus Torvalds has criticized Stallman for what he considers "black-and-white thinking" and bringing more harm than good to the free software community.^[35]

Stallman's staunch advocacy for free software inspired the Virtual Richard M. Stallman (vrms), software that analyzes the packages currently installed on a Debian GNU/Linux system, and report those that are from the non-free tree.^[36] Stallman would disagree with parts of Debian's definition of free software.^[37]

In 1999, Stallman called for development of a free on-line encyclopedia through the means of inviting the public to contribute articles.^[38] The resulting GNUPedia was eventually retired in favour of the emerging Wikipedia, which had similar aims and was enjoying greater success.^[39]

In Venezuela, Stallman has delivered public speeches and promoted the adoption of free software in the state's oil company (PDVSA), in municipal government, and in the nation's military. In meetings with Chávez and in public speeches, Stallman criticised some policies on television broadcasting, free speech rights, and privacy.^[40][41] Stallman was on the Advisory Council of Latin American television station teleSUR from its launch^[42] but resigned in February 2011, criticizing pro-Gaddafi propaganda during the 2011 North Africa uprisings.^[43]

In August 2006 at his meetings with the government of the Indian State of Kerala, he persuaded officials to discard proprietary software, such as Microsoft's, at state-run schools. This has resulted in a landmark decision to switch all school computers in 12,500 high schools from Windows to a free software operating system.^[44]

After personal meetings, Stallman has obtained positive statements about the free software movement from the then-President of India, Dr. A.P.J. Abdul Kalam,^[45] French 2007 presidential candidate Ségolène Royal,^[46] and the president of Ecuador Rafael Correa.^[47]

Stallman has participated in protests about software patents,^[48] DRM,^[49][50] and proprietary software.

Protesting against proprietary software in April 2006, Stallman held a "Don't buy from ATI, enemy of your freedom" placard at a speech by an ATI representative in the building where Stallman works, resulting in the police being called.^[51] ATI has since merged with AMD Corporation and has taken steps to make their hardware documentation available for use by the free software community.^[52]

Stallman has also helped and supported the International Music Score Library Project in getting back online, after it had been taken down on October 19, 2007 following a cease and desist letter from Universal Edition.^[53]

After the death of Steve Jobs, Stallman wrote the following eulogy:

Steve Jobs, the pioneer of the computer as a jail made cool, designed to sever fools from their freedom, has died.

As Chicago Mayor Harold Washington said of the corrupt former Mayor Daley, "I'm not glad he's dead, but I'm glad he's gone." Nobody deserves to have to die — not Jobs, not Mr. Bill, not even people guilty of bigger evils than theirs. But we all deserve the end of Jobs' malign influence on people's computing.

Unfortunately, that influence continues despite his absence. We can only hope his successors, as they attempt to carry on his legacy, will be less effective.

—Richard Stallman^[54]

Stallman's remark stirred up accusations of being in bad taste, while Eric S. Raymond, author of Cathedral and the Bazaar, summarized that Stallman's statement was not personal, but was simply criticizing walled gardens.^[55]

Stallman's only computer is a Lemote Yeeloong netbook (using the same company's Loongson processor) which he chose because it can run with 100% free software even at the BIOS level, stating "freedom is my priority. I've campaigned for freedom since 1983, and I am not going to surrender that freedom for the sake of a more convenient computer."^[56] Lemote is a joint venture of the Institute of Computing Technology of the Chinese Academy of Sciences, an institution of the State Council of China.

Stallman has suggested that the United States government may encourage^[57][58] the use of software as a service because this would allow them to access users' data without needing a search warrant.^[59][60][61]

Terminology[link]

Stallman places great importance on the words and labels people use to talk about the world, including the relationship between software and freedom. He untiringly asks people to say free software and GNU/Linux, and to avoid the terms intellectual property and piracy (in relation to copyright). His requests that people use certain terms, and his ongoing efforts to convince people of the importance of terminology are a source of regular misunderstanding and friction with parts of the free software and open source communities.

One of his criteria for giving an interview to a journalist is that the journalist agree to use his terminology throughout the article.^[62] Sometimes he has even required journalists to read parts of the GNU philosophy before an interview, for "efficiency's sake".^{[citation needed]} He has been known to turn down speaking requests over some terminology issues.^[63]

Stallman rejects a common alternative term, open source software, because it does not call to mind what Stallman sees as the value of the software: freedom.^[64] Thus it will not inform people of the freedom issues, and will not lead to people valuing and defending their freedom.^[65] Two alternatives which Stallman does accept are software libre and unfettered software, but free software is the term he asks people to use in English. For similar reasons, he argues for the term "proprietary software" rather than "closed source software", when referring to software that is not free software.

Stallman repeatedly asks that the term GNU/Linux, which he pronounces "GNU slash Linux", be used to refer to the operating system created by combining the GNU system and the Linux kernel. Stallman refers to this operating system as "a variant of GNU, and the GNU Project is its principal developer."^[63] He claims that the connection between the GNU project's philosophy and its software is broken when people refer to the combination as merely Linux.^[66] Starting around 2003, he began also using the term GNU+Linux, which he pronounces "GNU plus Linux", to prevent others from pronouncing the phrase "GNU/Linux" as "GNU Linux", which would erroneously imply that the Linux kernel is maintained by the GNU project. (See: GNU/Linux naming controversy)

Stallman argues that the term intellectual property is designed to confuse people, and is used to prevent intelligent discussion on the specifics of copyright, patent, trademark and other laws by lumping together areas of law that are more dissimilar than similar.^[67] He also argues that by referring to these laws as property laws, the term biases the discussion when thinking about how to treat these issues.

These laws originated separately, evolved differently, cover different activities, have different rules, and raise different public policy issues. Copyright law was designed to promote authorship and art, and covers the details of a work of authorship or art. Patent law was intended to encourage publication of ideas, at the price of finite monopolies over these ideas — a price that may be worth paying in some fields and not in others. Trademark law was not intended to promote any business activity, but simply to enable buyers to know what they are buying.^[68]

An example of cautioning others to avoid other terminology while also offering suggestions for possible alternatives, is this sentence of an email by Stallman to a public mailing list:

I think it is ok for authors (please let's not call them creators, they are not gods) to ask for money for copies of their works (please let's not devalue these works by calling them content) in order to gain income (the term compensation falsely implies it is a matter of making up for some kind of damages).^[69]

Personal life[link]

Stallman has devoted the bulk of his life’s energies to political and software activism.^[70] Professing to care little for material wealth, he explains that "I've always lived cheaply ... like a student, basically. And I like that, because it means that money is not telling me what to do."^[71]

Until around 1998, his office at MIT's AI Lab was also his residence.^[72] He was registered to vote from there. Nowadays he has a separate residence in Cambridge not far from MIT.^[73] His position as a research affiliate at MIT is unpaid.^[74]
