Zynga Inc. is an American social game developer running social video game services and founded in April 2007 with headquarters in San Francisco, California, United States. The company primarily focuses on mobile and social networking platforms. Zynga states its mission as "connecting the world through games."

Zynga launched its best-known game, FarmVille, on Facebook in June 2009, reaching 10 million daily active users (DAU) within six weeks. As of August 2017, Zynga had 30 million monthly active users (MAU). In 2017 its most successful games were Zynga Poker and Words with Friends 2, with about 57 million games being played at any given moment; and CSR Racing 2, the most popular racing game on mobile devices.

Zynga began trading on NASDAQ December 16, 2011, under the ticker ZNGA.

The Mozart effect is the theory that listening to the music of Mozart may temporarily boost scores on one portion of an IQ test. Popular science versions of the theory make the claim that "listening to Mozart makes you smarter" or that early childhood exposure to classical music has a beneficial effect on mental development.

The original study from 1993 reported a short-term (lasting about 15 minutes) improvement on the performance of certain kinds of mental tasks known as spatial reasoning, such as folding paper and solving mazes. The results were highly exaggerated by the popular press and became "Mozart makes you smart", which was said to apply to children in particular (the original study included 36 college students). These claims led to a commercial fad with Mozart CDs being sold to parents, the U.S. state of Georgia even proposed a budget to provide every child with a CD of classical music.

A meta-analysis of studies that have replicated the original study shows that there is little evidence that listening to Mozart has any particular effect on spatial reasoning. The author of the original study has stressed that listening to Mozart has no effect on general intelligence.

Karmarkar's algorithm is an algorithm introduced by Narendra Karmarkar in 1984 for solving linear programming problems. It was the first reasonably efficient algorithm that solves these problems in polynomial time. The ellipsoid method is also polynomial time but proved to be inefficient in practice.

Denoting ${\displaystyle n}$ as the number of variables and ${\displaystyle L}$ as the number of bits of input to the algorithm, Karmarkar's algorithm requires ${\displaystyle O(n^{3.5}L)}$ operations on ${\displaystyle O(L)}$-digit numbers, as compared to ${\displaystyle O(n^{6}L)}$ such operations for the ellipsoid algorithm. The runtime of Karmarkar's algorithm is thus

${\displaystyle O(n^{3.5}L^{2}\cdot \log L\cdot \log \log L),}$

using FFT-based multiplication (see Big O notation).

Karmarkar's algorithm falls within the class of interior-point methods: the current guess for the solution does not follow the boundary of the feasible set as in the simplex method, but moves through the interior of the feasible region, improving the approximation of the optimal solution by a definite fraction with every iteration and converging to an optimal solution with rational data.

Kostroma Moose Farm (Russian: Костромска́я лосефе́рма) is an experimental farm in Kostroma Oblast, Russia, where a herd of moose is kept, primarily for milk production; the farm supplies moose's milk to a nearby sanitorium. It is located near the village of Sumarokovo in Krasnoselsky District of Kostroma Oblast, some 25 km east of the city of Kostroma.

A zero-rupee note is a banknote imitation issued in India as a means of helping to fight systemic political corruption. The notes are "paid" in protest by angry citizens to government functionaries who solicit bribes in return for services which are supposed to be free. Zero rupee notes, which are made to resemble the regular 50 rupee banknote of India, are the creation of a non-governmental organization known as 5th Pillar which has, since their inception in 2007, distributed over 2.5 million notes as of August 2014. The notes remain in current use and thousands of notes are distributed every month.

🔗 Business

Founder's syndrome (also founderitis) is the difficulty faced by organizations where one or more founders maintain disproportionate power and influence following the effective initial establishment of the project, leading to a wide range of problems for the organization. The passion and charisma of the founder(s), sources of the initial creativity and productivity of the organization, become limiting or destructive factors. The syndrome occurs in both non-profit and for-profit organizations. It may simply limit further growth and success of the project, or it may lead to bitter factionalism and divisions as the scale of demands made on the organization increases, or it may result in outright failure. There are ways in which a founder or organization can respond and grow beyond this situation.

User:Diikiw/Wiikid, formerly Wikiid, is an article that was created on the web site Wikipedia in 2008. It is notable in its attempt to become the first Wikipedia page to gain notoriety solely for the fact that it was a page on Wikipedia; this was intended to spark a debate as to whether or not Wikipedia could be considered a source notable enough to allow a page’s permanent entry on the site. It can be looked at both as metahumor and as a piece of postmodern art.
