Software bug

A software bug is an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. Most bugs arise from mistakes and errors made by people in either a program's source code or its design, or in frameworks and operating systems used by such programs, and a few are caused by compilers producing incorrect code. A program that contains a large number of bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy or defective. Reports detailing bugs in a program are commonly known as bug reports, defect reports, fault reports, problem reports, trouble reports, change requests and so forth.

Bugs trigger errors that may in turn have a wide variety of ripple effects with varying levels of inconvenience to the user of the program. Some bugs have only a subtle effect on the program's functionality, and may thus lie undetected for a long time. More serious bugs may cause the program to crash or freeze. Others qualify as security bugs and might, for example, enable a malicious user to bypass access controls in order to obtain unauthorized privileges.

Computer programming

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable computer programs. Programming involves activities such as analysis, developing understanding, generating algorithms, verification of requirements of algorithms including their correctness and resources consumption, and implementation (commonly referred to as coding) of algorithms in a target programming language. Source code is written in one or more programming languages. The purpose of programming is to find a sequence of instructions that will automate performing a specific task or solving a given problem. The process of programming thus often requires expertise in many different subjects, including knowledge of the application domain, specialized algorithms and formal logic.

Related tasks include testing, debugging, and maintaining the source code, implementation of the build system, and management of derived artifacts such as machine code of computer programs. These might be considered part of the programming process, but often the term software development is used for this larger process with the term programming, implementation, or coding reserved for the actual writing of source code. Software engineering combines engineering techniques with software development practices.

Computer (disambiguation)

A computer is a program machine that receives input, stores and manipulates data, and provides output in a useful format.

Computer may also refer to:

Human computer

The term "computer", in use from the early 17th century (the first known written reference dates from 1613), meant "one who computes": a person performing mathematical calculations, before electronic computers became commercially available. "The human computer is supposed to be following fixed rules; he has no authority to deviate from them in any detail." (Turing, 1950) Teams of people were frequently used to undertake long and often tedious calculations; the work was divided so that this could be done in parallel.

The first time the term "Computer" appeared in The New York Times was February 3, 1853; an obituary stated:

Since the end of the 20th century, the term "human computer" has also been applied to individuals with prodigious powers of mental arithmetic, also known as mental calculators.

Origins in astronomy

The approach was taken for astronomical and other complex calculations. Perhaps the first example of organized human computing was by the Frenchman Alexis Claude Clairaut (1713–1765), when he divided the computation to determine timing of the return of Halley's Comet with two colleagues, Joseph Lalande and Nicole-Reine Lepaute.

List of Courage the Cowardly Dog characters

This is a list of characters from the Cartoon Network animated series, Courage the Cowardly Dog.

Main characters

Courage

Courage is the series' protagonist, and an overly frightened purple beagle dog who lives in Nowhere, Kansas. He was abandoned as a puppy after his parents were sent into outer space, but was adopted by Muriel Bagge. Her husband, Eustace, regularly mistreats him. Ironically, given his name, Courage is a genuine coward, but still goes to great lengths to protect his owners; to the end, he often gets injured, sometimes quite brutally, or almost killed and only surviving through his determination and/or pure luck. Despite his cowardice, Courage is very clever and resourceful when the situation demands it, outsmarting the villains most of the time. Aiding him at saving the day is a self-aware, sarcastic and seemingly omniscient Computer that he keeps in the attic with which he could consult for information in how to remedy any predicament he faces (though it never fails to badmouth him in one way or another). He got his name when Muriel found him as a puppy alone in an alley and remarked that he must be quite brave to be there by himself.

Bug!

Bug! is a 3D rendered platform/adventure video game developed by Realtime Associates for the Sega Saturn. Released in 1995 as a launch game for the Saturn in North America, it was one of the earliest 3D platform games. It was later localized to Europe and Japan, then ported to Windows 3.x and Windows 95 on August 31, 1996 by Beam Software, on one CD that contains both versions of the game.

A sequel was released in 1996, Bug Too!.

Plot

The background plot centers around the title character, Bug!, a famous Hollywood star hoping to make his "biggest break" ever. Players take control shortly after Bug! has signed up a deal for the lead role in an action film in which his girlfriend is kidnapped by Queen Cadavra and must set out to rescue her. The gameplay takes place "on the set" of each scene and cutscenes between levels indicate Bug! moving over from one set to the next.

Gameplay

Bug! was played like a traditional side-scrolling adventure game. In the same fashion as Sonic the Hedgehog , Bug! must jump and stung on the heads of his enemies to defeat them while making his way through large levels and collecting power-ups. What sets Bug! apart is the game's 3D levels, which take the side-view and tweak it. Bug! can walk sidewise up vertical surfaces and even upside down. Each set of levels (ranging from a bright, green grassy area to a deep red, desert level) has a deeply individual look and feel.

Bug (2006 film)

Bug is a 2006 American psychological horror film directed by William Friedkin. It stars Ashley Judd, Michael Shannon and Harry Connick, Jr.. The screenplay by Tracy Letts is based on his 1996 play of the same name in which a woman holed up in a rural Oklahoma motel becomes involved with a paranoid man obsessed with conspiracy theories about insects and the government. Bug debuted at the 2006 Cannes Film Festival before being purchased by Lions Gate Films, who released the film the following year in May 2007.

Friedkin and Letts similarly collaborated on the 2011 film Killer Joe.

Plot

Agnes White is a waitress at a gay bar living in a run-down motel in rural Oklahoma. Unable to move on from the disappearance of her son some years previously, she engages in drug and alcohol binges with her lesbian friend, R.C. Lately, she has been plagued by silent telephone calls that she believes are being made by her abusive ex-husband, Jerry Goss, who has recently been released from prison.
