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.

Chant

A chant (from French chanter) is the rhythmic speaking or singing of words or sounds, often primarily on one or two main pitches called reciting tones. Chants may range from a simple melody involving a limited set of notes to highly complex musical structures, often including a great deal of repetition of musical subphrases, such as Great Responsories and Offertories of Gregorian chant. Chant may be considered speech, music, or a heightened or stylized form of speech. In the later Middle Ages some religious chant evolved into song (forming one of the roots of later Western music).

Chant as a spiritual practice

Chanting (e.g., mantra, sacred text, the name of God/Spirit, etc.) is a commonly used spiritual practice. Like prayer, chant may be a component of either personal or group practice. Diverse spiritual traditions consider chant a route to spiritual development.

Some examples include chant in African, Hawaiian, and Native American, and Australian Aboriginal cultures, Gregorian chant, Vedic chant, Qur'an reading, Islamic Dhikr, Baha'i chants, various Buddhist chants, various mantras, Jewish cantillation, and the chanting of psalms and prayers especially in Roman Catholic (see Gregorian chant or Taizé Community), Eastern Orthodox (see Byzantine chant or Znamenny chant, for examples), Lutheran, and Anglican churches (see Anglican Chant).

Chant (Donald Byrd album)

Chant is an album by American trumpeter Donald Byrd recorded in 1961 but not released on the Blue Note label until 1979.

Reception

Allmusic awarded the album 4½ stars and the review by Scott Yanow states, "This is superior hard bop from the early '60s".

Chant (crater)

Chant is a lunar impact crater that is located on the far side of the Moon, behind the southwest limb as seen from the Earth. It lies within the southwestern part of the blanket of ejecta surrounding the Mare Orientale, beyond the Montes Cordillera mountain ring. To the west-northwest is the large walled plain Blackett. Southward is the crater Mendel.

This is a nearly circular crater with a slight outward bulge in the northeast wall. The outer rim is sharp-edged, and the inner sides slope directly downward with only some minor terraces along the east wall. The interior floor is somewhat irregular, particularly in the southern half. There is a small central peak at the midpoint of the floor.

The name Chant was officially adopted by the International Astronomical Union in 1970.

This crater lies to the northwest of the Mendel-Rydberg Basin, a 630 km wide impact basin of Nectarian age.
