Jasper Fish

Jasper Fish (buried 28 July 1791 at Sevenoaks, Kent) was a noted professional cricketer in the 18th century who was chiefly associated with Kent in the 1760s and 1770s.

Most of his career took place before cricket's statistical record began with regular scorecards in 1772 and he is recorded in only three major cricket matches in 1769, 1773 and 1777.

Fish anatomy

Fish anatomy is the study of the form or morphology of fishes. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.

The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure.

Fish physiology

Fish physiology is the scientific study of how the component parts of fish function together in the living fish. It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes.

Respiration

Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of threadlike structures called filaments. These filaments have many functions and "are involved in ion and water transfer as well as oxygen, carbon dioxide, acid and ammonia exchange. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx.

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 (memory cache)

Velocity was the code name for a distributed key-value cache platform for in-memory caches spread across multiple systems, developed by Microsoft. It is now incorporated as the caching element of Microsoft's AppFabric.

Design

Any number of systems can be a part of the cache; the velocity runtime pools together the individual caches on each machine to present a unified view to the applications. Applications need not know on which machine the cache is stored; rather the applications query the Velocity runtime which in turn, forwards the request to the system that houses the cache item. The Velocity API is surfaced in managed code; so any CLI-compliant language can be used to access the Velocity cache. Any serialized managed object can be added to the cache.
