Yhprum’s Law

yhprum

Yhprum’s Law is the opposite of Murphy’s Law (Yhprum = Murphy backwards). The simple formula of Yhprum’s Law is: ‘Everything, that can work, will work. It is attributed to Richard Zeckhauser, a professor for political economy at Harvard University: ‘Sometimes systems that should not work, work nevertheless.’

In 2006, Paul Resnick of the University of Michigan School of Information used this law to describe how intensive and seemingly altruistic participation by giving ranking is observed in the eBay system.

Hanlon’s Razor

conspiracy by xkcd

Hanlon’s Razor is an eponymous adage that reads: ‘Never attribute to malice that which is adequately explained by stupidity.’

A common (and more laconic) British English variation, coined by Sir Bernard Ingham, is the saying ‘cock-up before conspiracy,’ deriving from this quotation: ‘Many journalists have fallen for the conspiracy theory of government. I do assure you that they would produce more accurate work if they adhered to the cock-up theory.’

Resistentialism

Resistentialism [ri-zis-ten-shul-iz-um] is a jocular theory to describe ‘seemingly spiteful behavior manifested by inanimate objects.’ For example, objects that cause problems (like lost keys or a fleeing bouncy ball) exhibit a high degree of malice toward humans and lend support to resistentialist beliefs. In other words, a war is being fought between humans and inanimate objects, and all the little annoyances objects give people throughout the day are battles between the two.

The term was coined by humorist Paul Jennings in a piece titled ‘Report on Resistentialism,’ published in ‘The Spectator’ in 1948 and reprinted in ‘The New York Times.’ The movement is a spoof of existentialism in general, and Jean-Paul Sartre in particular (Jennings gives the inventor of Resistentialism as Pierre-Marie Ventre). The slogan of Resistentialism is ‘Les choses sont contre nous’ — ‘Things are against us.’ Continue reading

Intentional Stance

The intentional stance is a term coined by philosopher Daniel Dennett for the level of abstraction in which we view the behavior of a thing in terms of mental properties. It is part of a theory of mental content proposed by Dennett, which provides the underpinnings of his later works on free will, consciousness, folk psychology, and evolution.

‘Here is how it works: first you decide to treat the object whose behavior is to be predicted as a rational agent; then you figure out what beliefs that agent ought to have, given its place in the world and its purpose. Then you figure out what desires it ought to have, on the same considerations, and finally you predict that this rational agent will act to further its goals in the light of its beliefs. A little practical reasoning from the chosen set of beliefs and desires will in most instances yield a decision about what the agent ought to do; that is what you predict the agent will do.’

Cradle-to-cradle

c2c

waste equals food

Cradle-to-cradle design (C2C) is a biomimetic approach to the design of systems. It models human industry on nature’s processes in which materials are viewed as nutrients circulating in healthy, safe metabolisms. It suggests that industry must protect and enrich ecosystems and nature’s biological metabolism while also maintaining safe, productive technical metabolism for the high-quality use and circulation of organic and synthetic  materials.

Put simply, it is a holistic economic, industrial and social framework that seeks to create systems that are not just efficient but essentially waste free. The model in its broadest sense is not limited to industrial design and manufacturing; it can be applied to many different aspects of human civilization such as urban environments, buildings, economics, and social systems.

Amitron

amitron

The Amitron was an electric concept car built in 1967 by American Motors Corporation (AMC) and Gulton Industries of Metuchen, New Jersey. It was a snub-snouted three-passenger urban area vehicle or city car with an overall length of only 85 inches.

Roy D. Chapin, Jr., Chairman and CEO of AMC, stated that the Amitron ‘could eliminate many problems that up to this point have made electric-type cars impractical.’ Continue reading

Regenerative Brake

dynamic braking

kers

A regenerative brake is an energy recovery mechanism which slows a vehicle or object down by converting its kinetic energy into another form, which can be either used immediately or stored until needed. This contrasts with conventional braking systems, where the excess kinetic energy is converted to heat by friction in the brake linings and therefore wasted. The most common form of regenerative brake involves using an electric motor as an electric generator.

In electric railways the generated electricity is fed back into the supply system, whereas in battery electric and hybrid electric vehicles, the energy is stored in a battery or bank of capacitors for later use. Energy may also be stored mechanically via pneumatics, hydraulics, or the kinetic energy of a rotating flywheel. Continue reading

Flywheel

KERS

A flywheel is a heavy disk or wheel that is attached to a rotating shaft. Flywheels are used for storage of kinetic energy. The momentum of the flywheel causes it to not change its rotational speed easily. Because of this, flywheels help to keep the shaft rotating at the same speed. This helps when the torque applied to the shaft changes often.

Torque refers to turning or twisting force. If a force is used to begin to spin an object, or to stop an object from spinning, torque is required. Uneven torque can change the speed of rotation. Because the flywheel resists changes in speed, it decreases the effects of uneven torque. Engines which use pistons to provide power usually have uneven torque and use flywheels to fix this problem.

Abandonware

abandonia

Abandonware are discontinued products for which no product support is available, or whose copyright ownership may be unclear for various reasons. Abandonware may be computer software or physical devices which are usually computerized in some fashion, such as personal computer games, productivity applications, utility software, or mobile phones.

Definitions of ‘abandoned’ vary; generally it refers to a product that is no longer available for legal purchase, over the age where the product creator feels an obligation to continue to support it, or where operating systems or hardware platforms have evolved to such a degree that the creator feels continued support cannot be financially justified. Software companies and manufacturers may change their names, go bankrupt, enter into mergers, or cease to exist for a variety of reasons. When this happens, product rights are usually transferred to another company that may elect not to sell or support products acquired. Continue reading

Sid Meier’s Alpha Centauri

alpha centauri

Sid Meier’s Alpha Centauri (SMAC) is a science fiction 4X (explore, expand, exploit, exterminate), turn-based strategy video game sequel to the ‘Civilization’ series. Sid Meier, designer of ‘Civilization,’ and Brian Reynolds, designer of ‘Civilization II,’ developed ‘Alpha Centauri’ after they left MicroProse to join the newly created developer Firaxis Games. Electronic Arts released both SMAC and its expansion, ‘Sid Meier’s Alien Crossfire’ (SMAX), in 1999. In the following year, both titles were ported to Mac and Linux.

Set in the 22nd century, the game begins as seven competing ideological factions land on the planet Chiron (‘Planet’) in the Alpha Centauri star system. As the game progresses, Planet’s growing sentience becomes a formidable obstacle to the human colonists. Alpha Centauri features improvements on Civ II’s game engine, including simultaneous multiplay, social engineering, climate, customizable units, alien native life, additional diplomatic and spy options, additional ways to win, and greater mod-ability. ‘Alien Crossfire’ introduces five new human and two non-human factions as well as additional technologies, facilities, secret projects, native life, unit abilities, and a victory condition.

Sid Meier’s Civilization

sid meier

Sid Meier’s Civilization is a turn-based strategy video game created by Sid Meier and Bruce Shelley for MicroProse in 1991. It is a standard-bearer for the 4X genre: eXplore (reveal surrounding territories), eXpand (create new settlements), eXploit (gather resources), and eXterminate (eliminate rivals). The game’s objective is to ‘Build an empire to stand the test of time.’ It begins in 4000 BCE and the players attempt to expand and develop their empires through the ages from the ancient era until modern and near-future times. The game requires a fair amount of micromanagement (although less than a simulation game such as SimCity).

Along with the larger tasks of exploration, warfare, and diplomacy, the player has to make decisions about where to build new cities, which improvements or units to build in each city, which advances in knowledge should be sought (and at what rate), and how to transform the land surrounding the cities for maximum benefit. From time to time the player’s towns may be harassed by barbarians, units with no specific nationality and no named leader. These threats only come from unclaimed land or sea, so that over time there are fewer and fewer places from which barbarians will emanate.

4X

civ

4X games are a genre of strategy video game in which players control an empire and ‘explore (reveal surrounding territories), expand (create new settlements), exploit (gather resources), and exterminate’ (eliminate rivals). The four elements often overlap with each other and vary in length depending on the game design.

For example, the ‘Space Empires’ series and ‘Galactic Civilizations II’ have lengthy expansion phases, because players must make large investments in research to explore and expand into every area. The term was first coined by video game critic Alan Emrich in his 1993 preview of ‘Master of Orion’ for ‘Computer Gaming World,’ in which he rated the game ‘XXXX’ as a pun on the rating for pornography.
