The Republic of Indian Stream or Indian Stream Republic was an unrecognized constitutional republic in North America, along the section of the border that divides the current Canadian province of Quebec from the U.S. state of New Hampshire. It existed from July 9, 1832, to August 5, 1835. Described as "Indian Stream Territory, so-called" by the United States census-taker in 1830, the area was named for Indian Stream, a small watercourse. It had an organized elected government and constitution and served about three hundred citizens.

Conway's law is an adage stating that organizations design systems that mirror their own communication structure. It is named after computer programmer Melvin Conway, who introduced the idea in 1967. His original wording was:

Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.

The law is based on the reasoning that in order for a software module to function, multiple authors must communicate frequently with each other. Therefore, the software interface structure of a system will reflect the social boundaries of the organization(s) that produced it, across which communication is more difficult. Conway's law was intended as a valid sociological observation, although sometimes it's used in a humorous context. It was dubbed Conway's law by participants at the 1968 National Symposium on Modular Programming.

In colloquial terms, it means software or automated systems end up "shaped like" the organizational structure they are designed in or designed for. Some interpretations of the law say this organizational pattern mirroring is a helpful feature of such systems, while other interpretations say it's merely a result of human nature or organizational bias.

🔗 Typography

"The quick brown fox jumps over the lazy dog" is an English-language pangram—a sentence that contains all of the letters of the alphabet. It is commonly used for touch-typing practice, testing typewriters and computer keyboards, displaying examples of fonts, and other applications involving text where the use of all letters in the alphabet is desired. Owing to its brevity and coherence, it has become widely known.

The 2020 stock market crash is a global stock market crash that began on 20 February, 2020. On 12 February, the Dow Jones Industrial Average, the NASDAQ Composite, and S&P 500 Index all finished at record highs (while the NASDAQ and S&P 500 reached subsequent record highs on 19 February). From 24 to 28 February, stock markets worldwide reported their largest one-week declines since the 2008 financial crisis, thus entering a correction. Global markets into early March became extremely volatile, with large swings occurring in global markets. On 9 March, most global markets reported severe contractions, mainly in response to the 2019–20 coronavirus pandemic and an oil price war between Russia and the OPEC countries led by Saudi Arabia. This became colloquially known as Black Monday I, and at the time was the worst drop since the Great Recession in 2008.

Three days after Black Monday I there was another drop, Black Thursday, where stocks across Europe and North America fell more than 9%. Wall Street experienced its largest single-day percentage drop since Black Monday in 1987, and the FTSE MIB of the Borsa Italiana fell nearly 17%, becoming the worst-hit market during Black Thursday. Despite a temporary rally on 13 March (with markets posting their best day since 2008), all three Wall Street indexes fell more than 12% when markets re-opened on 16 March. At least one benchmark stock market index in all G7 countries and 14 of the G20 countries have been declared to be in bear markets.

As of March 2020, global stocks have seen a downturn of at least 25% during the crash, and 30% in most G20 nations. Goldman Sachs has warned that the US GDP will shrink 29% by the end of the 2nd quarter of 2020, and that unemployment may skyrocket to at least 9%. Australian Prime Minister Scott Morrison has called the looming economic crisis 'akin to the Great Depression'.

The Tech Model Railroad Club (TMRC) is a student organization at the Massachusetts Institute of Technology (MIT). Historically it has been a wellspring of hacker culture and the oldest such hacking group in North America. Formed in 1946, its HO scale layout specializes in automated operation of model trains.

🔗 Radio Stations

United Biscuits Network (UBN) was an internal radio station serving the factories of United Biscuits (UB) in Britain that operated from 1970 to 1979.

In 1970 the BBC had a monopoly on radio broadcasting in Britain, although there were a few offshore pirate radio broadcasters, such as Radio Caroline. At one time factories had sought to avoid unnecessary background sound, but during the Second World War psychologists found that light background music (muzak) increased productivity at times it was low, a trend that continued after the war. But as jobs became deskilled and ever more monotonous, muzak became less effective, and staff turnover increased. United Biscuits was affected by this trend; Hector Laing, the managing director in the 1960s, needed to reduce the costs of high staff turnover. Inspired by the success of the pirate stations, Laing hired suitable staff, bought state-of-the-art broadcasting equipment, and set up UBN at UB headquarters in Osterley, west London (later the headquarters of broadcaster Sky UK).

Arcosanti is a projected experimental town with a molten bronze bell casting business in Yavapai County, central Arizona, 70 mi (110 km) north of Phoenix, at an elevation of 3,732 feet (1,130 meters). Its arcology concept was posited by the Italian-American architect, Paolo Soleri (1919–2013). He began construction in 1970, to demonstrate how urban conditions could be improved while minimizing the destructive impact on the earth. He taught and influenced generations of architects and urban designers who studied and worked with him there to build the proposed "town".

Oblique Strategies (subtitled Over One Hundred Worthwhile Dilemmas) is a card-based method for promoting creativity jointly created by Brian Eno and Peter Schmidt, first published in 1975. Physically, it takes the form of a deck of 7-by-9-centimetre (2.8 in × 3.5 in) printed cards in a black box. Each card offers a challenging constraint intended to help artists (particularly musicians) break creative blocks by encouraging lateral thinking.
