Hacker may refer to:
In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge, enjoyment, or to evaluate those weaknesses to assist in removing them. The subculture that has evolved around hackers is often referred to as the computer underground and is now a known community. While other uses of the word hacker exist that are not related to computer security, such as referring to someone with an advanced understanding of computers and computer networks, they are rarely used in mainstream context. They are subject to the longstanding hacker definition controversy about the term's true meaning. In this controversy, the term hacker is reclaimed by computer programmers who argue that someone who breaks into computers, whether computer criminal (black hats) or computer security expert (white hats), is more appropriately called a cracker instead. Some white hat hackers claim that they also deserve the title hacker, and that only black hats should be called "crackers".
Hacker II: The Doomsday Papers is a 1986 computer game developed and published by Activision. It is the sequel to the 1985 game, Hacker. It was released for several platforms of the home computer era. As with the first game, it was designed by Steve Cartwright.
Hacker II is notably more difficult and involved than the first game. In Hacker II, the player is actually recruited based upon his (assumed) success with the activities in the original game. Once again, they are tasked with controlling a robot, this time to infiltrate a secure facility in order to retrieve documents known only as "The Doomsday Papers" from a well guarded vault to ensure the security of the United States.
Eventually, as they escape with the papers, the player is confronted by agents of the United States who reveal that he or she have actually been working for a former Magma employee, who wanted the papers in revenge for what had happened to the company the player had presumably exposed in the first game. The building that the player had unwittingly broken into was a government facility. The player then has to go back into the facility as part of a gambit to expose the Magma agent, avoiding the same security that had threatened the player before.
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.
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.
