Anonymous pipe

In computer science, an anonymous pipe is a simplex FIFO communication channel that may be used for one-way interprocess communication (IPC). An implementation is often integrated into the operating system's file IO subsystem. Typically a parent program opens anonymous pipes, and creates a new process that inherits the other ends of the pipes, or creates several new processes and arranges them in a pipeline.

Full-duplex (two-way) communication normally requires two anonymous pipes.

Pipelines are supported in most popular operating systems, from Unix and DOS onwards, and are created using the "|" character.

Unix

Pipelines are an important part of many traditional Unix applications and support for them is well integrated into most Unix-like operating systems. Pipes are created using the pipe system call, which creates a new pipe and returns a pair of file descriptors referring to the read and write ends of the pipe. Many traditional Unix programs are designed as filters to work with pipes.

Pipeline (Unix)

In Unix-like computer operating systems (and, to some extent, Microsoft Windows), a pipeline is a set of processes chained by their standard streams, so that the output of each process (stdout) feeds directly as input (stdin) to the next one. Filter programs are often used in this configuration.

The concept of pipelines was invented by Douglas McIlroy at Unix's ancestral home of Bell Labs, prior to the actual invention of the operating system, and implemented in Unix at his insistence, shaping its toolbox philosophy. It is named by analogy to a physical pipeline. The standard shell syntax for pipelines is to list multiple programs to invoke in one command, separated by vertical bars:

Each program is assumed to take input and give output on its standard streams. Each "|" tells the shell to connect the standard output of the left program to the standard input of the right program by an inter-process communication mechanism called an (anonymous) pipe, implemented in the operating system. Since pipes are unidirectional, data flows through the pipeline from left to right.

Organ pipe

An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air (commonly referred to as wind) is driven through it. Each pipe is tuned to a specific note of the musical scale. A set of organ pipes of similar timbre tuned to a scale is known as a rank or a stop.

Construction

Materials

Organ pipes are generally made out of either metal or wood. Very rarely, glass, porcelain, plastic, paper, Papier-mâché, or even stone pipes may be seen. A historical organ in the Philippines has pipes made exclusively of bamboo.

Metal

Metal pipes are usually made of lead; for increased rigidity it is alloyed with tin along with trace amounts of antimony and copper. The percentage of each metal in the alloy influences the characteristics of the resulting pipe. A high proportion of tin results in a slightly brighter colouring. In addition, high amounts of tin give a gleaming and long-lasting polish, which may be desired if the pipe is clearly visible. The cost of each metal is also a factor, as tin is more expensive than lead. Cost considerations may also lead to the use of the inferior rolled zinc especially for the lower tones that take a lot of material. In addition, pipes have been made of many metals, including copper, aluminium, gold electroplate, silver, brass, and iron.

Character design of Final Fantasy

Although each installment of the Final Fantasy series is generally set in a different fictional world with separate storylines, there are several commonalities when it comes to character design, as certain design themes repeat themselves, as well as specific character names and classes. Within the main series, Yoshitaka Amano was the character designer for Final Fantasy, Final Fantasy II, Final Fantasy III, Final Fantasy IV, Final Fantasy V and Final Fantasy VI, Tetsuya Nomura was the character designer for Final Fantasy VII, Final Fantasy VIII, Final Fantasy X, Final Fantasy XI and Final Fantasy XIII, Yoshitaka Amano created and did the concept art for the characters while Toshiyuki Itahana was the final character designer for Final Fantasy IX, and Akihiko Yoshida was the character designer for Final Fantasy XII.

Visual character design

The series has often featured male characters with slightly effeminate characteristics, as well as female characters with slightly tomboyish, but still feminine, characteristics. This trend has generally increased as the series evolved. These characters are usually teenagers, which some critics have interpreted as an effort on the part of the designers to ensure the players identify with them. At the same time, some female characters have been increasingly designed to wear very revealing outfits. Square Enix has stated that a more rugged looking hero had been considered for Final Fantasy XII but had ultimately been scrapped in favor of Vaan, another effeminate protagonist. The developers cited scenaristic reasons and target demographic considerations to explain their choice. For Final Fantasy XIII, Square Enix settled on a female main character, described as a "female version of Cloud from FFVII." This aspect of Final Fantasy can also be seen in Sora, the protagonist of Kingdom Hearts, a crossover series featuring Final Fantasy and Disney characters.

F.A.M.E. (album)

F.A.M.E. is the fourth studio album by American recording artist Chris Brown. It was first released on March 18, 2011, by Jive Records. The album serves as the follow-up to his third album Graffiti (2009). The album also marks as his last album with Jive Records. On this album, Brown worked with several record producers and songwriters; including Kevin McCall, Jean-Baptiste, Brian Kennedy, DJ Frank E, The Underdogs and The Messengers, among others. The album features guest appearances, from Wiz Khalifa, Game, Timbaland and Big Sean, among others.

Musically, F.A.M.E. combines the musical genres of R&B, pop, hip hop and Europop. Upon its release, the album received mixed reviews from most music critics, who were ambivalent towards its songwriting and material. The album debuted at number one on the US Billboard 200, with first-week sales of 270,000, Brown's first number-one album in the United States. It was certified gold by the Recording Industry Association of America (RIAA), for selling more than 500,000 copies. The album garnered three Grammy Award nominations at the 54th annual ceremony, eventually winning Best R&B Album. F.A.M.E. also won the Album of the Year at the 2011 Soul Train Music Awards.

Box office bomb

In the motion picture industry, a "box office bomb" or "box office flop" is a film that is viewed as highly unsuccessful or unprofitable during its theatrical run, sometimes preceding hype regarding its cost, production, or marketing efforts. Generally, any film for which the production and marketing costs exceed the combined revenue recovered after release is considered to have "bombed".

Gauging the financial success of a film is difficult, and because there is no reliable definition, what makes a "box-office bomb" can be very subjective. Not all films that fail to earn back their estimated costs during their theatrical runs are "bombs," and the label is generally applied to films that miss earnings projections by a wide margin, particularly when they are very expensive to produce, and sometimes in conjunction with middling or poor reviews (though critical reception has an imperfect connection to box office performance).

Causes of a film's failure

Negative word of mouth

Beginning in the 1980s, cinemas started to drop movies that suffered a poor opening weekend. This made the performance of a film on its opening weekend much more crucial to its perception. With the growth of the Internet during the 1990s, chat rooms and websites enabled negative word of mouth to spread rapidly.
