Black

Black is the darkest color, the result of the absence of or complete absorption of light. It is the opposite of white (the combined spectrum of color or light). It is an achromatic color, literally a color without color or hue. It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors.

Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.

In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches and magic. According to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, evil, and elegance.

White and Black in chess

In chess, the player who moves first is referred to as "White" and the player who moves second is referred to as "Black". Similarly, the pieces that each conducts are called, respectively, "the white pieces" and "the black pieces". The pieces are often not literally white and black, but some other colors (usually a light color and a dark color, respectively). The 64 squares of the chessboard, which is colored in a checkered pattern, are likewise referred to as "white squares" or "light squares" on the one hand, and "black squares" or "dark squares" on the other. In most cases, the squares are not actually white and black, but a light color and a contrasting dark color. For example, the squares on plastic boards are often off-white ("buff") and green, while those on wood boards are often light brown and dark brown.

In old chess writings, the sides are often called Red and Black, because those were the two colors of ink then commonly available when hand-drawing or printing chess position diagrams.

Black (2004 film)

Black: The Man From Darkness is a 2004 Indian Malayalam crime thriller film written and directed by Ranjith, and produced by Lal. It deals with the underworld operations in Kochi. Mammootty plays the role of Police Constable Karikkamuri Shanmugham, who ironically is a hit man and a contract killer. The film features cinematography by Amal Neerad. The film was a comeback for actor Rahman to Malayalam cinema. The film was a box office hit.

Plot

Black is based on the underground activities in the city of Kochi(Cochin). Shanmughan (Mammooty) plays a Head Police Constable but also a hitman who does his job with perfection. On the top of the underworld, there is a man, Advocate Devin Carlos Padaveedan (Lal). He and Shanmughan are accomplices.

A newly appointed police officer, Ashok (Rahman), tries to clean up the city from the criminals, but fails to do so as he is killed by Padaveedan. Shanmugan is not very happy about the death of Ashok, and creates some indifference between the friends. After Shanmugan finds his own daughter, he wants to live a peaceful life, but the transformation is not acceptable to Padaveedan, and he wants Shanmughan dead.

OpenNIC

OpenNIC is an alternate network information center/alternative DNS root which lists itself as an alternative to ICANN and its registries.

As of 2006 users of the OpenNIC DNS servers are able to resolve all existing ICANN top-level domains as well as their own.

Like all alternative root DNS systems, OpenNIC-hosted domains are unreachable to the vast majority of the Internet. Only specific configuration in one's DNS resolver makes these reachable, and very few Internet service providers have this configuration.

History

On June 1, 2000, an article was posted on kuro5hin.org advocating a democratically governed domain name system. By the end of July, OpenNIC root servers were operating and several top-level domains had been introduced as well as peering of the AlterNIC namespace. In March 2001 peering began of Pacific Root and in September a search engine was announced which was dedicated to the OpenNIC namespace.

OpenNIC restructured its architecture to improve scalability and avoid single-point-of-failure issues. Each TLD has its own policies regarding acceptable use. New TLDs may be created subject to OpenNIC stated policies.

XLR-11 (drug)

XLR-11 (5"-fluoro-UR-144) is a drug that acts as a potent agonist for the cannabinoid receptors CB₁ and CB₂ with EC₅₀ values of 98 nM and 83 nM, respectively. It is a 3-(tetramethylcyclopropylmethanoyl)indole derivative related to compounds such as UR-144, A-796,260 and A-834,735, but it is not specifically listed in the patent or scientific literature alongside these other similar compounds, and appears to have not previously been made by Abbott Laboratories, despite falling within the claims of patent WO 2006/069196. XLR-11 was found to produce rapid, short-lived hypothermic effects in rats at doses of 3 mg/kg and 10 mg/kg, suggesting that it is of comparable potency to APICA and STS-135.

Detection

A forensic standard for this compound is available, and a representative mass spectrum has been posted on Forendex. An ELISA immunoassay technique for detecting XLR-11 and UR-144 in blood and urine as part of general drug screens has been developed by Randox Laboratories and Tulip Biolabs, Inc.
