π Satellite killed by trajectory patent
AMC-14 is a communications satellite. Initially owned by SES Americom, AMC-14 was designed to be placed in geostationary orbit, following launch on a Proton rocket. Built by Lockheed Martin and based on the A2100 satellite bus, AMC-14 was to have been located at 61.5Β° west longitude for DISH Network service.
It was launched atop a Proton-M/Briz-M rocket at 23:18:55 GMT on 14 March 2008, from LC-200/39 at the Baikonur Cosmodrome in Kazakhstan. The satellite was placed in an unusable orbit, following a malfunction of the Briz-M upper stage. Over a six-month period, it was maneuvered into a geosynchronous orbit, and is now near 35Β° East and in an inclined orbit.

π Unlambda
Unlambda is a minimal, "nearly pure" functional programming language invented by David Madore. It is based on combinatory logic, an expression system without the lambda operator or free variables. It relies mainly on two built-in functions (s
and k
) and an apply operator (written `
, the backquote character). These alone make it Turing-complete, but there are also some input/output (I/O) functions to enable interacting with the user, some shortcut functions, and a lazy evaluation function. Variables are unsupported.
Unlambda is free and open-source software distributed under a GNU General Public License (GPL) 2.0 or later.

π ACTA will force border searches of laptops, smartphones for pirated content
The Anti-Counterfeiting Trade Agreement (ACTA) was a proposed multilateral treaty for the purpose of establishing international standards for intellectual property rights enforcement. The agreement aims to establish an international legal framework for targeting counterfeit goods, generic medicines and copyright infringement on the Internet, and would create a new governing body outside existing forums, such as the World Trade Organization, the World Intellectual Property Organization, and the United Nations.
The agreement was signed in October 2011 by Australia, Canada, Japan, Morocco, New Zealand, Singapore, South Korea, and the United States. In 2012, Mexico, the European Union and 22 countries that are member states of the European Union signed as well. One signatory (Japan) has ratified (formally approved) the agreement, which would come into force in countries that ratified it after ratification by six countries.
Industrial groups with interests in copyright, trademarks and other types of intellectual property said that ACTA was a response to "the increase in global trade of counterfeit goods and pirated copyright protected works". Organizations such as the Motion Picture Association of America and International Trademark Association are understood to have had a significant influence over the ACTA agenda.
Organisations representing citizens and non-governmental interests argued that ACTA could infringe fundamental rights including freedom of expression and privacy. ACTA has also been criticised by Doctors Without Borders for endangering access to medicines in developing countries. The nature of negotiations was criticized as secretive and has excluded non-governmental organization, developing countries and the general public from the agreement's negotiation process and it has been described as policy laundering by critics including the Electronic Frontier Foundation and the Entertainment Consumers Association.
The signature of the EU and many of its member states resulted in widespread protests across Europe. European Parliament rapporteur Kader Arif resigned. His replacement, British MEP David Martin, recommended that the Parliament should reject ACTA, stating: "The intended benefits of this international agreement are far outweighed by the potential threats to civil liberties". On 4 July 2012, the European Parliament declined its consent, effectively rejecting it, 478 votes to 39, with 165 abstentions.

π The Alan Turing Year 2012
The Alan Turing Year, 2012, marked the celebration of the life and scientific influence of Alan Turing during the centenary of his birth on 23 June 1912. Turing had an important influence on computing, computer science, artificial intelligence, developmental biology, and the mathematical theory of computability and made important contributions to code-breaking during the Second World War. The Alan Turing Centenary Advisory committee (TCAC) was originally set up by Professor Barry Cooper
The international impact of Turing's work is reflected in the list of countries in which Alan Turing Year was celebrated, including: Bolivia, Brazil, Canada, China, Czech Republic, France, Germany, India, Israel, Italy, Netherlands, Mexico, New Zealand, Norway, Philippines, Portugal, Spain, Switzerland, U.K. and the U.S.A. 41+ countries were involved.
π First president with a CS degree?
Herman Cain (born December 13, 1945) is an American politician, business executive, syndicated columnist, and Tea Party activist.
Cain grew up in Georgia and graduated from Morehouse College with a bachelor's degree in mathematics. He then graduated with a master's degree in computer science at Purdue University, while also working full-time for the U.S. Department of the Navy. In 1977, he joined the Pillsbury Company where he later became vice president. During the 1980s, Cain's success as a business executive at Burger King prompted Pillsbury to appoint him as chairman and CEO of Godfather's Pizza, in which capacity he served from 1986 to 1996.
Cain was chairman of the Federal Reserve Bank of Kansas City Omaha Branch from 1989 to 1991. He was deputy chairman, from 1992 to 1994, and then chairman until 1996, of the Federal Reserve Bank of Kansas City. In 1995, he was appointed to the Kemp Commission, and in 1996, he served as a senior economic adviser to Bob Dole's presidential campaign. From 1996 to 1999, Cain served as president and CEO of the National Restaurant Association.
In May 2011, Cain announced his presidential candidacy. By the fall, his proposed 9β9β9 tax plan and debating performances had made him a serious contender for the Republican nomination. In November, however, his campaign faced allegations of sexual misconductβall denied by Cainβand he announced its suspension on December 3.

π Parrondo's paradox
Parrondo's paradox, a paradox in game theory, has been described as: A combination of losing strategies becomes a winning strategy. It is named after its creator, Juan Parrondo, who discovered the paradox in 1996. A more explanatory description is:
- There exist pairs of games, each with a higher probability of losing than winning, for which it is possible to construct a winning strategy by playing the games alternately.
Parrondo devised the paradox in connection with his analysis of the Brownian ratchet, a thought experiment about a machine that can purportedly extract energy from random heat motions popularized by physicist Richard Feynman. However, the paradox disappears when rigorously analyzed. Winning strategies consisting of a combinations of losing strategies have been explored in biology before Parrondo's paradox was published. More recently, problems in evolutionary biology and ecology have been modeled and explained in terms of the paradox.

π Guy Fawkes Day
Guy Fawkes Night, also known as Guy Fawkes Day, Bonfire Night (predominantly Newfoundland) and Firework Night, is an annual commemoration observed on 5Β November, primarily in the United Kingdom. Its history begins with the events of 5Β November 1605 O.S., when Guy Fawkes, a member of the Gunpowder Plot, was arrested while guarding explosives the plotters had placed beneath the House of Lords. Celebrating the fact that King James I had survived the attempt on his life, people lit bonfires around London; and months later, the introduction of the Observance of 5th November Act enforced an annual public day of thanksgiving for the plot's failure.
Within a few decades Gunpowder Treason Day, as it was known, became the predominant English state commemoration, but as it carried strong Protestant religious overtones it also became a focus for anti-Catholic sentiment. Puritans delivered sermons regarding the perceived dangers of popery, while during increasingly raucous celebrations common folk burnt effigies of popular hate-figures, such as the pope. Towards the end of the 18th century reports appear of children begging for money with effigies of Guy Fawkes and 5Β November gradually became known as Guy Fawkes Day. Towns such as Lewes and Guildford were in the 19th century scenes of increasingly violent class-based confrontations, fostering traditions those towns celebrate still, albeit peaceably. In the 1850s changing attitudes resulted in the toning down of much of the day's anti-Catholic rhetoric, and the Observance of 5th November Act was repealed in 1859. Eventually the violence was dealt with, and by the 20th century Guy Fawkes Day had become an enjoyable social commemoration, although lacking much of its original focus. The present-day Guy Fawkes Night is usually celebrated at large organised events, centred on a bonfire and extravagant firework displays.
Settlers exported Guy Fawkes Night to overseas colonies, including some in North America, where it was known as Pope Day. Those festivities died out with the onset of the American Revolution. Claims that Guy Fawkes Night was a Protestant replacement for older customs like Samhain are disputed, although another old celebration, Halloween, has lately increased in popularity in England, and according to some writers, may threaten the continued observance of 5Β November.

π John McCarthy Has Died
John McCarthy (September 4, 1927 β October 24, 2011) was an American computer scientist and cognitive scientist. McCarthy was one of the founders of the discipline of artificial intelligence. He coined the term "artificial intelligence" (AI), developed the Lisp programming language family, significantly influenced the design of the ALGOL programming language, popularized time-sharing, invented garbage collection, and was very influential in the early development of AI.
McCarthy spent most of his career at Stanford University. He received many accolades and honors, such as the 1971 Turing Award for his contributions to the topic of AI, the United States National Medal of Science, and the Kyoto Prize.

π Carl Fisher
Carl Graham Fisher (January 12, 1874Β β July 15, 1939) was an American entrepreneur. Despite severe astigmatism, he became actively involved in auto racing. He was a seemingly tireless pioneer and promoter of the automotive industry and highway construction, and of real estate development in Florida. He is widely regarded as a promotional genius.
Despite family financial strains and a disability, in the late 19th century he became a bicycle enthusiast and opened a modest bicycle shop with a brother. He became involved in bicycle racing, as well as many activities related to the emerging American auto industry. In 1904, Carl Fisher and his friend James A. Allison bought an interest in the U.S. patent to manufacture acetylene headlights, a precursor to electric models which became common about ten years later. Soon Fisher's firm supplied nearly every headlamp used on automobiles in the United States as manufacturing plants were built all over the country to supply the demand. The headlight patent made him rich as an automotive parts supplier when he and Allison sold their company, Prest-O-Lite, to Union Carbide in 1913 for $9 million (equivalent of approximately $230 million in 2019).
Fisher operated in Indianapolis what is believed to be the first automobile dealership in the United States, and also worked at developing an automobile racetrack locally. After being injured in stunts himself, and following a safety debacle at the new Indianapolis Motor Speedway, of which he was a principal, he helped develop paved racetracks and public roadways. Improvements he implemented at the speedway led to its nickname, "The Brickyard."
In 1912, Fisher conceived and helped develop the Lincoln Highway, the first road for the automobile across the entire United States of America. A convoy trip a few years later by the U.S. Army along Fisher's Lincoln Highway was a major influence upon then Lt. Col. Dwight D. Eisenhower years later in championing the Interstate Highway System during his presidency in the 1950s.
Carl Fisher followed the east-west Lincoln Highway in 1914 with the conception of the north-south Dixie Highway, which led from Michigan to Miami. Under his leadership, the initial portion was completed within a single year, and he led an automobile caravan to Florida from Indiana.
At the south end of the Dixie Highway in Miami, Florida, Fisher, with the assistance of his partners John Graham McKay and Thomas Walkling, became involved in the successful real estate development of the new resort city of Miami Beach, built on a largely unpopulated barrier island and reached by the new Collins Bridge across Biscayne Bay directly at the terminus of the Dixie Highway. Fisher was one of the best known and active promoters of the Florida land boom of the 1920s. By 1926, he was worth an estimated $100Β million, and redirected his promotional efforts when the Florida real estate market bubble burst after 1925. His final major project, cut short by the Great Depression, was a "Miami Beach of the north" at Montauk, located at the eastern tip of Long Island, New York.
His fortune was lost in the Stock Market Crash of 1929 and the Great Depression in the United States which followed shortly thereafter. He found himself living in a small cottage in Miami Beach, doing minor work for old friends. Nevertheless, years after his fortune had been lost, at the end of his career, he took on one more project, albeit more modest than many of his past ventures, and built the famous Caribbean Club on Key Largo, intended as a "poor man's retreat."
Although he had lost his fortune and late in life considered himself a failure, Fisher is widely regarded as a decidedly successful man in the long view of his life. He was inducted into the Automotive Hall of Fame in 1971. In a 1998 study judged by a panel of 56 historians, writers, and others, Carl G. Fisher was named one of the Fifty Most Influential People in the history of the State of Florida by The Ledger newspaper. PBS labeled him "Mr. Miami Beach." Just south of Miami Beach, Fisher Island (which he once owned, and is named for him), became one of the wealthiest and most exclusive residential areas in the United States.
