Fred Fish (November 4, 1952 – April 20, 2007) was a computer programmer notable for work on the GNU Debugger and his series of freeware disks for the Amiga.

The Amiga Library Disks – colloquially referred to as Fish Disks (a term coined by Perry Kivolowitz at a Jersey Amiga User Group meeting) – became the first national rallying point, a sort of early postal system. Fish would distribute his disks around the world in time for regional and local user group meetings, which in turn duplicated them for local distribution. Typically, only the cost of materials changed hands. The Fish Disk series ran from 1986 to 1994. In it, one can chart the growing sophistication of Amiga software and see the emergence of many software trends.

The Fish Disks were distributed at computer stores and Amiga enthusiast clubs. Contributors submitted applications and source code and the best of these each month were assembled and released as a diskette. Since the Internet was not yet in popular usage outside military and university circles, this was a primary way for enthusiasts to share work and ideas. He also initiated the "GeekGadgets" project, a GNU standard environment for AmigaOS and BeOS.

Fish worked for Cygnus Solutions in the 1990s before he left for Be Inc. in 1998.

In 1978, he self-published User Survival Guide for TI-58/59 Master Library, which was advertised in enthusiast newsletters covering the TI-59 programmable calculator.

🔗 Sailing

The Vestas Sailrocket was built to capture the sailing speed record competing in the B-class for 150 to 235 square feet of sail. It is piloted by the project leader Paul Larsen and sponsored by Danish wind turbines manufacturer Vestas. In 2008 the first version reached a reported unofficial speed of 52.22 knots (96.71 km/h), before crashing.

After being upgraded to a second version, the Vestas Sailrocket 2 began a campaign to break speed records in November 2012 off Walvis Bay, Namibia. On 12 November, it made a 54.08 knots (100.16 km/h) run over a 500 metres (1,600 ft) distance, then 59.23 knots (109.69 km/h) on the 16th. It attained 55.32 knots (102.45 km/h) on a one-mile run on the 18th and simultaneously 59.38 knots (109.97 km/h) on 500m. On 24 November, with wind speeds at roughly 25 knots (46 km/h), it ran the 500m course at 65.45 knots (121.21 km/h) with a 68.01 knots (125.95 km/h) peak. Both records are ratified by the World Sailing Speed Record Council (WSSRC) for the 500m and the mile.

A Swiss team of École Polytechnique Fédérale de Lausanne university students and engineers, including members involved in the development of previous record-holder Hydroptère, formed in October 2019 to develop a new hydrofoil boat, SP80, to exceed the Vestas Sailrocket 2 record in 2022, with a target speed of 80 knots. As of April 2023, the speed record attempts were pushed back to 2024 and are scheduled to take place in Leucate.

Mary Mallon (September 23, 1869 – November 11, 1938), also known as Typhoid Mary, was an Irish-born cook believed to have infected 53 people with typhoid fever, three of whom died, and the first person in the United States identified as an asymptomatic carrier of the disease, Salmonella typhi. Because she persisted in working as a cook, by which she exposed others to the disease, she was twice forcibly quarantined by authorities, eventually for the final two decades of her life. Mallon died after a total of nearly 30 years in isolation.

🔗 Songs

"Old Man Trump" is a song with lyrics written by American folk singer-songwriter Woody Guthrie in 1954. The song describes the racist housing practices and discriminatory rental policies of his landlord, Fred Trump (the father of the 45th president of the United States, Donald Trump). Although the lyrics were written in 1954, it was never recorded by Guthrie. In January 2016, Will Kaufman, a Guthrie scholar and professor of American literature and culture at the University of Central Lancashire, unearthed the handwritten lyrics while conducting research at the Woody Guthrie Archives in Tulsa, Oklahoma.

In political jargon, a useful idiot is a derogatory term for a person perceived as propagandizing for a cause without fully comprehending the cause's goals, and who is cynically used by the cause's leaders. The term was originally used during the Cold War to describe non-communists regarded as susceptible to communist propaganda and manipulation. The term has often been attributed to Vladimir Lenin, but this attribution is unsubstantiated.

M-Pesa (M for mobile, pesa is Swahili for money) is a mobile phone-based money transfer, financing and microfinancing service, launched in 2007 by Vodafone for Safaricom and Vodacom, the largest mobile network operators in Kenya and Tanzania. It has since expanded to Afghanistan, South Africa, India and in 2014 to Romania and in 2015 to Albania. M-Pesa allows users to deposit, withdraw, transfer money and pay for goods and services (Lipa na M-Pesa) easily with a mobile device.

The service allows users to deposit money into an account stored on their cell phones, to send balances using PIN-secured SMS text messages to other users, including sellers of goods and services, and to redeem deposits for regular money. Users are charged a small fee for sending and withdrawing money using the service.

M-Pesa is a branchless banking service; M-Pesa customers can deposit and withdraw money from a network of agents that includes airtime resellers and retail outlets acting as banking agents.

M-Pesa has spread quickly, and by 2010 had become the most successful mobile-phone-based financial service in the developing world. By 2012, a stock of about 17 million M-Pesa accounts had been registered in Kenya. By June 2016, a total of 7 million M-Pesa accounts have been opened in Tanzania by Vodacom. The service has been lauded for giving millions of people access to the formal financial system and for reducing crime in otherwise largely cash-based societies.

The Roseto effect is the phenomenon by which a close-knit community experiences a reduced rate of heart disease. The effect is named for Roseto, Pennsylvania. The Roseto effect was first noticed in 1961 when the local Roseto doctor encountered Dr. Stewart Wolf, then head of Medicine of the University of Oklahoma, and they discussed, over a couple of beers, the unusually low rate of myocardial infarction in the Italian American community of Roseto compared with other locations. Many studies followed, including a 50-year study comparing Roseto to nearby Bangor. As the original authors had predicted, as the Roseto cohort shed their Italian social structure and became more Americanized in the years following the initial study, heart disease rates increased, becoming similar to those of neighboring towns.

From 1954 to 1961, Roseto had nearly no heart attacks for the otherwise high-risk group of men 55 to 64, and men over 65 had a death rate of 1% while the national average was 2%. Widowers outnumbered widows, as well.

These statistics were at odds with a number of other factors observed in the community. They smoked unfiltered stogies, drank wine "with seeming abandon" in lieu of milk and soft drinks, skipped the Mediterranean diet in favor of meatballs and sausages fried in lard with hard and soft cheeses. The men worked in the slate quarries where they contracted illnesses from gases and dust. Roseto also had no crime, and very few applications for public assistance.

Wolf attributed Rosetans' lower heart disease rate to lower stress. "'The community,' Wolf says, 'was very cohesive. There was no keeping up with the Joneses. Houses were very close together, and everyone lived more or less alike.'" Elders were revered and incorporated into community life. Housewives were respected, and fathers ran the families.

José Alberto "Pepe" Mujica Cordano (Spanish: [xoˈse muˈxika]; born 20 May 1935) is a Uruguayan politician and farmer who served as the 40th President of Uruguay from 2010 to 2015. A former guerrilla with the Tupamaros, he was tortured and imprisoned for 14 years during the military dictatorship in the 1970s and 1980s. A member of the Broad Front coalition of left-wing parties, Mujica was Minister of Livestock, Agriculture, and Fisheries from 2005 to 2008 and a Senator afterwards. As the candidate of the Broad Front, he won the 2009 presidential election and took office as President on 1 March 2010.

He has been described as "the world's humblest head of state" due to his austere lifestyle and his donation of around 90 percent of his $12,000 monthly salary to charities that benefit poor people and small entrepreneurs. An outspoken critic of capitalism’s focus on stockpiling material possessions which do not contribute to human happiness, Pepe is often seen riding his 60-year-old bicycle. The Times Higher Education called him the "philosopher president" in 2015, a play on words of Plato's conception of the philosopher king.

A sun dog (or sundog) or mock sun, formally called a parhelion (plural parhelia) in meteorology, is an atmospheric optical phenomenon that consists of a bright spot to one or both sides of the Sun. Two sun dogs often flank the Sun within a 22° halo.

The sun dog is a member of the family of halos, caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun. They can be seen anywhere in the world during any season, but are not always obvious or bright. Sun dogs are best seen and most conspicuous when the Sun is near the horizon.
