π Heilmeier's Catechism: questions for every startup, every project.
George Harry Heilmeier (May 22, 1936 β April 21, 2014) was an American engineer, manager, and a pioneering contributor to liquid crystal displays (LCDs), for which he was inducted into the National Inventors Hall of Fame. Heilmeier's work is an IEEE Milestone.
π Bert Sutherland Has Died
William Robert Sutherland (May 10, 1936Β β February 18, 2020) was an American computer scientist who was the longtime manager of three prominent research laboratories, including Sun Microsystems Laboratories (1992β1998), the Systems Science Laboratory at Xerox PARC (1975β1981), and the Computer Science Division of Bolt, Beranek and Newman, Inc. which helped develop the ARPANET.
In these roles, Sutherland participated in the creation of the personal computer, the technology of advanced microprocessors, the Smalltalk programming language, the Java programming language and the Internet.
Unlike traditional corporate research managers, Sutherland added individuals from fields like psychology, cognitive science, and anthropology to enhance the work of his technology staff. He also directed his scientists to take their research, like the Xerox Alto "personal" computer, outside of the laboratory to allow people to use it in a corporate setting and to observe their interaction with it.
In addition, Sutherland fostered a collaboration between the researchers at California Institute of Technology developing techniques of very large scale integrated circuits (VLSI)Β β his brother Ivan and Carver MeadΒ β and Lynn Conway of his PARC staff. With PARC resources made available by Sutherland, Mead and Conway developed a textbook and university syllabus that helped expedite the development and distribution of a technology whose effect is now immeasurable.
Sutherland said that a research lab is primarily a teaching institution, "teaching whatever is new so that the new can become familiar, old, and used widely."
Sutherland was born in Hastings, Nebraska on May 10, 1936, to a father from New Zealand; his mother was from Scotland. The family moved to Wilmette, Illinois, then Scarsdale, New York, for his father's career. Bert Sutherland graduated from Scarsdale High School, then received his bachelor's degree in electrical engineering from Rensselaer Polytechnic Institute (RPI), and his master's degree and Ph.D. from Massachusetts Institute of Technology (MIT); his thesis advisor was Claude Shannon. During his military service in the United States Navy, he was awarded the Legion of Merit as a Carrier ASW plane commander. He was the older brother of Ivan Sutherland. Bert Sutherland died on February 18, 2020, aged 83.

π Fred Hampton
Fredrick Allen Hampton (August 30, 1948 β December 4, 1969) was an American activist and revolutionary socialist. He came to prominence in Chicago as chairman of the Illinois chapter of the Black Panther Party (BPP), and deputy chairman of the national BPP. In this capacity, he founded a prominent multicultural political organization, the Rainbow Coalition that initially included the Black Panthers, Young Patriots and the Young Lords, and an alliance among major Chicago street gangs to help them end infighting, and work for social change.
In 1967, Hampton was identified by the Federal Bureau of Investigation as a radical threat. The FBI tried to subvert his activities in Chicago, sowing disinformation among these groups and placing a counterintelligence operative in the local Panthers. In December 1969, Hampton was shot and killed in his bed during a predawn raid at his Chicago apartment by a tactical unit of the Cook County State's Attorney's Office in conjunction with the Chicago Police Department and the Federal Bureau of Investigation; during the raid, another Panther was killed and several seriously wounded. In January 1970, a coroner's jury held an inquest and ruled the deaths of Hampton and Mark Clark to be justifiable homicide.
A civil lawsuit was later filed on behalf of the survivors and the relatives of Hampton and Clark. It was resolved in 1982 by a settlement of $1.85 million; the City of Chicago, Cook County, and the federal government each paid one-third to a group of nine plaintiffs. Given revelations about the illegal COINTELPRO program and documents associated with the killings, scholars now widely consider Hampton's death an assassination under the FBI's initiative.

π Pine Gap, Australia
Pine Gap is the commonly used name for a US satellite surveillance base and Australian Earth station approximately 18 kilometres (11Β mi) south-west of the town of Alice Springs, Northern Territory in the centre of Australia which is jointly operated by Australia and the United States. Since 1988, it has been officially called the Joint Defence Facility Pine Gap (JDFPG); previously, it was misleadingly known as Joint Defence Space Research Facility.
The station is partly run by the US Central Intelligence Agency (CIA), US National Security Agency (NSA), and US National Reconnaissance Office (NRO) and is a key contributor to the NSA's global interception effort, which included the ECHELON program. The classified NRO name of the Pine Gap base is Australian Mission Ground Station (AMGS), while the unclassified cover term for the NSA function of the facility is RAINFALL.

π The Negro Motorist Green Book
The Negro Motorist Green Book (also The Negro Motorist Green-Book, The Negro Travelers' Green Book, or simply the Green Book) was an annual guidebook for African-American roadtrippers. It was originated and published by African American, New York City mailman Victor Hugo Green from 1936 to 1966, during the era of Jim Crow laws, when open and often legally prescribed discrimination against African Americans especially and other non-whites was widespread. Although pervasive racial discrimination and poverty limited black car ownership, the emerging African-American middle class bought automobiles as soon as they could, but faced a variety of dangers and inconveniences along the road, from refusal of food and lodging to arbitrary arrest. In response, Green wrote his guide to services and places relatively friendly to African-Americans, eventually expanding its coverage from the New York area to much of North America, as well as founding a travel agency.
Many black Americans took to driving, in part to avoid segregation on public transportation. As the writer George Schuyler put it in 1930, "all Negroes who can do so purchase an automobile as soon as possible in order to be free of discomfort, discrimination, segregation and insult." Black Americans employed as athletes, entertainers, and salesmen also traveled frequently for work purposes.
African-American travelers faced hardships such as white-owned businesses refusing to serve them or repair their vehicles, being refused accommodation or food by white-owned hotels, and threats of physical violence and forcible expulsion from whites-only "sundown towns". Green founded and published the Green Book to avoid such problems, compiling resources "to give the Negro traveler information that will keep him from running into difficulties, embarrassments and to make his trip more enjoyable." The maker of a 2019 documentary film about the book offered this summary: "Everyone I was interviewing talked about the community that the Green Book created: a kind of parallel universe that was created by the book and this kind of secret road map that the Green Book outlined".
From a New York-focused first edition published in 1936, Green expanded the work to cover much of North America, including most of the United States and parts of Canada, Mexico, the Caribbean, and Bermuda. The Green Book became "the bible of black travel during Jim Crow", enabling black travelers to find lodgings, businesses, and gas stations that would serve them along the road. It was little known outside the African-American community. Shortly after passage of the Civil Rights Act of 1964, which outlawed the types of racial discrimination that had made the Green Book necessary, publication ceased and it fell into obscurity. There has been a revived interest in it in the early 21st century in connection with studies of black travel during the Jim Crow era.
Four issues (1940, 1947, 1954, and 1963) have been republished in facsimile (as of December 2017), and have sold well. Twenty-three additional issues have now been digitized by the New York Public Library Digital Collections.

π Go Away Green
Go Away Green refers to a range of paint colors used in Disney Parks to divert attention away from infrastructure. It has been compared to military camouflage like Olive Drab.
Imagineer John Hench wrote about developing such colors, "We chose a neutral gray-brown for the railing, a 'go away' color that did not call attention to itself, even though it was entirely unrelated to the Colonial color scheme."
Large attraction buildings visible either inside or outside a park such as Soarinβ at California Adventure or Indiana Jones Adventure at Disneyland are often painted a muted green. Necessary in-park infrastructure like speakers, lamp posts, fences, trash cans, and the former entrance to Club 33 are also painted various shades of green.
This concept also extends to grays, browns, and blues for spaces with less greenery or buildings that extend above the tree line, such as Guardians of the Galaxy: Cosmic Rewind.
