🔗 Brands 🔗 Electronics

The Capacitance Electronic Disc (CED) is an analog video disc playback system developed by RCA, in which video and audio could be played back on a TV set using a special needle and high-density groove system similar to phonograph records.

First conceived in 1964, the CED system was widely seen as a technological success which was able to increase the density of a long-playing record by two orders of magnitude. Despite this achievement, the CED system fell victim to poor planning, various conflicts with RCA management, and several technical difficulties that slowed development and stalled production of the system for 17 years—until 1981, by which time it had already been made obsolete by laser videodisc (DiscoVision, later called LaserVision and LaserDisc) as well as Betamax and VHS video cassette formats. Sales for the system were nowhere near projected estimates. In the spring of 1984, RCA announced it was discontinuing player production, but continuing the production of videodiscs until 1986, losing an estimated $600 million in the process. RCA had initially intended to release the SKT425 CED player with their high end Dimensia system in late 1984, but cancelled CED player production prior to the Dimensia system's release.

The format was commonly known as "videodisc", leading to much confusion with the contemporaneous LaserDisc format. LaserDiscs are read optically with a laser beam, whereas CED discs are read physically with a stylus (similar to a conventional gramophone record). The two systems are mutually incompatible.

RCA used the brand "SelectaVision" for the CED system, a name also used for some early RCA brand VCRs, and other experimental projects at RCA.

🔗 Psychology

Bedtime procrastination or revenge bedtime procrastination is a psychological phenomenon in which people stay up later than they desire in an attempt to have control over the night because they perceive themselves (perhaps subconsciously) to lack influence over events during the day.

🔗 Ships 🔗 Egypt

The Yellow Fleet was the name given to a group of fifteen ships trapped in the Suez Canal (in the Great Bitter Lake section) from 1967 to 1975 as a result of the Israel-Egypt Six-Day War. Both ends of the canal had been blocked by the Egyptians with scuttled ships and other obstacles. The name Yellow Fleet derived from their yellow appearance as they were increasingly covered in a desert sand swept on board. After eight years, the only ships that were able to return to their home port under their own power were the West German ships Münsterland and Nordwind.

Engines of Creation: The Coming Era of Nanotechnology is a 1986 molecular nanotechnology book written by K. Eric Drexler with a foreword by Marvin Minsky. An updated version was released in 2007. The book has been translated into Japanese, French, Spanish, Italian, Russian, and Chinese.

🔗 Aviation 🔗 Disaster management 🔗 Aviation/Aviation accident 🔗 Canada 🔗 Aviation/aircraft 🔗 Aviation/gliding 🔗 Canada/History of Canada 🔗 Canada/Manitoba

Air Canada Flight 143 was a Canadian scheduled domestic passenger flight between Montreal and Edmonton that ran out of fuel on July 23, 1983, at an altitude of 41,000 feet (12,000 m), midway through the flight. The crew was able to glide the Boeing 767 aircraft safely to an emergency landing at a former Royal Canadian Air Force base in Gimli, Manitoba, that had been turned into a motor racing track. This unusual aviation incident earned the aircraft the nickname "Gimli Glider".

The subsequent investigation revealed that a combination of company failures, human errors and confusion over unit measures had led to the aircraft being refuelled with insufficient fuel for the planned flight.

🔗 Economics 🔗 Futures studies

Pessimism porn is a neologism coined in 2009 during the 2007–2012 global financial crisis to describe the alleged eschatological and survivalist thrill some people derive from predicting, reading and fantasizing about the collapse of civil society through the destruction of the world's economic system.

A kibbutz (Hebrew: קִבּוּץ‎ / קיבוץ‎, lit. "gathering, clustering"; plural: kibbutzim קִבּוּצִים‎ / קיבוצים‎) is a collective community in Israel that was traditionally based on agriculture. The first kibbutz, established in 1909, was Degania. Today, farming has been partly supplanted by other economic branches, including industrial plants and high-tech enterprises. Kibbutzim began as utopian communities, a combination of socialism and Zionism. In recent decades, some kibbutzim have been privatized and changes have been made in the communal lifestyle. A member of a kibbutz is called a kibbutznik (Hebrew: קִבּוּצְנִיק‎ / קיבוצניק‎; plural kibbutznikim or kibbutzniks).

In 2010, there were 270 kibbutzim in Israel. Their factories and farms account for 9% of Israel's industrial output, worth US$8 billion, and 40% of its agricultural output, worth over $1.7 billion. Some kibbutzim had also developed substantial high-tech and military industries. For example, in 2010, Kibbutz Sasa, containing some 200 members, generated $850 million in annual revenue from its military-plastics industry.

Currently the kibbutzim are organised in the secular Kibbutz Movement with some 230 kibbutzim, the Religious Kibbutz Movement with 16 kibbutzim and the much smaller religious Poalei Agudat Yisrael with two kibbutzim, all part of the wider communal settlement movement.
