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.

Hot (Taeyang album)

Hot is the first extended play (EP) and first solo album by Korean singer Taeyang, member of Big Bang. The album was well received by fans and critics alike, winning two trophies from The 6th Korean Music Awards for the 2008 Best R&B/Soul Song (나만 바라봐, "Only Look At Me") and the 2008 Best R&B/Soul Album (Hot). Taeyang is the first "Idol group" or boyband member to receive such awards.

Two singles were released from the album, "Gido" (Hangul: 기도; "Prayer") and "Naman Barabwa" (Hangul: "나만 바라봐"; "Only Look At Me"), with music videos produced for each song. "Make Love" from this album was remade by Big Bang to be featured in their Japanese album Number 1. Bandmate G-Dragon recorded a "Part two" version of "Only Look At Me", and released it as a digital single, "나만 바라봐 Part 2 (Only Look At Me Part 2)." Both versions were performed at the M.Net MKMF Awards, where each member of Big Bang performed a song with Korean singer Hyori Lee.

Hot (Inna song)

"Hot" is a song by Romanian dance/pop vocalist Inna extracted from her debut studio album Hot 2009. Written and produced by Sebastian Barac, Radu Bolfea and Marcel Botezan of Play & Win, "Hot" was released late as the lead single from her debut record. The song is an uptempo electro house song, with it containing elements of trance music. Lyrically, it tells a story of how strong a connection between two lovers can become. Contemporary critics received "Hot" very well, with reviewers complimenting its beats, simplicity and effectiveness.

The track was a commercial success, reaching the top-ten in Belgium, Spain, Hungary, Czech Republic, France, Netherlands and Romania. "Hot" has been accompanied by two European club-themed official music video versions, with the first being released on 10 November 2008. Inna has promoted the song at various gigs across Europe and has also performed it on the 2009 Eska Music Awards, Legendario Ice Experience, Loop Live and the Sopot Hit Festival in Poland.

Hook (diacritic)

In typesetting, the hook or tail is a diacritic mark attached to letters in many alphabets. In shape it looks like a hook and it can be attached below as a descender, on top as an ascender and sometimes to the side. The orientation of the hook can change its meaning: when it is below and curls to the left it can be interpreted as a palatal hook, and when it curls to the right is called hook tail or tail and can be interpreted as a retroflex hook. It should not be mistaken with the hook above, a diacritical mark used in Vietnamese, or the rhotic hook, used in the International Phonetic Alphabet.

Letters with hook

It could be argued that the hook was used to derive the letter J from the letter I, or the letter Eng (ŋ) from the letter N. However, these letters are usually not identified as being formed with the hook.

Most letters with hook are used in the International Phonetic Alphabet, and many languages use them (along with capitals) representing the same sounds.

The hook often attaches to the top part of the letter, sometimes replacing the ascender.

Tail (song)

"Tail" is the first single by Powderfinger from their debut album Parables for Wooden Ears. The music video for "Tail" appeared on the bonus DVD of Dream Days at the Hotel Existence. The version used in the video is shorter and slightly different in instrumentation.
