Velocity (software development)

Velocity is a capacity planning tool sometimes used in Agile software development. Velocity tracking is the act of measuring said velocity. The velocity is calculated by counting the number of units of work completed in a certain interval, the length of which is determined at the start of the project.

Principle

The main idea behind velocity is to help teams estimate how much work they can complete in a given time period based on how quickly similar work was previously completed.

Terminology

The following terminology is used in velocity tracking.

Usage

To calculate velocity, a team first has to determine how many units of work each task is worth and the length of each interval. During development, the team has to keep track of completed tasks and, at the end of the interval, count the number of units of work completed during the interval. The team then writes down the calculated velocity in a chart or on a graph.

The first week provides little value, but is essential to provide a basis for comparison. Each week after that, the velocity tracking will provide better information as the team provides better estimates and becomes more used to the methodology.

Velocity (TV channel)

Velocity (formerly HD Theater and originally Discovery HD Theater) is an American high-definition, commercial-based, cable and satellite television channel owned by Discovery Communications. The channel specializes in nonfictional programming, focusing on cars, sports related shows, and other programming targeted at men ages 18–54.

As of February 2015, approximately 62.3 million American households (53.5% of households with television) receive Velocity.

History

The channel launched nationwide in the United States on June 17, 2002, as Discovery HD Theater. The channel was rebranded to HD Theater on September 22, 2007, because Discovery Communications launched HD simulcasts of some of its other channels including Animal Planet, Discovery Channel, Science and TLC.

On April 14, 2011, Discovery Communications announced that HD Theater would be re-launched as Velocity later in the year: aimed primarily at an "upscale male" audience, the network focuses primarily on automotive-oriented programming and other shows of interest to a male audience. The re-launch took place on October 4, 2011.

Velocity (novel)

Velocity is a novel by Dean Koontz first published in 2005. Set in Napa County, California, it is about a man in his thirties who takes the law into his own hands when, out of the blue, he is threatened by an anonymous adversary. The "words of wisdom" with which the novel is interspersed are direct quotations from the writings of T. S. Eliot.

Plot summary

Not so long ago a promising young short story writer, Billy Wiles has not even turned on his PC since his fiancée Barbara fell into a coma several years ago. Leading the life of a recluse who spends his spare time alone at home doing woodwork, he only leaves his secluded house when he goes to work as a bartender. An orphan, he only associates with few people, and he considers them acquaintances rather than friends.

Wiles's life takes a dramatic turn when he finds a piece of paper stuck to his windshield which contains an ultimatum (see book cover, below). He decides not to go to the police and to consult someone he knows who happens to be in the police force instead. Together, although not thoroughly convinced, the two men decide that the note must have been some sick joke.

Tears

Tearing (/ˈtiərɪŋ/), lacrimation, or lachrymation, (from Latin lacrima, meaning "tear") is the secretion of tears, which often serves to clean and lubricate the eyes in response to an irritation of the eyes. Tears formed through crying are associated with strong internal emotions, such as sorrow, elation, emotion, love, awe or pleasure. Laughing or yawning may also lead to the production of tears.

Physiology

In humans, the tear film coating the eye, known as the precorneal film, has three distinct layers, from the most outer surface:

Having a thin tear film may prevent one's ability to wear contact lenses, as the amount of oxygen needed is higher than normal, and contact lenses stop oxygen from entering the eye. Eyes with thin tear film will dry out while wearing contact lenses. Special eye drops are available for contact lens wearers. Certain types of contact lenses are designed to let more oxygen through to the eye.

Drainage of tear film

The lacrimal glands secrete lacrimal fluid, which flows through the main excretory ducts into the space between the eyeball and lids. When the eyes blink, the lacrimal fluid is spread across the surface of the eye. Lacrimal fluid gathers in the lacrimal lake, and is drawn into the puncta by capillary action, then flows through the lacrimal canaliculi at the inner corner of the eyelids entering the lacrimal sac, then on to the nasolacrimal duct, and finally into the nasal cavity. An excess of tears, as with strong emotion, can thus cause the nose to run.

Instant Pleasure (album)

Instant Pleasure is Rockell's second album, released on October 10, 2000 on Robbins Entertainment. It is more pop oriented than her debut and was mostly produced by Tony Moran and Hex Hector. The album features the hit singles "What U Did 2 Me", "Tears" and "The Dance".
