Software release life cycle

A software release life cycle is the sum of the stages of development and maturity for a piece of computer software: ranging from its initial development to its eventual release, and including updated versions of the released version to help improve software or fix bugs still present in the software.

History

Usage of the "alpha/beta" test terminology originated at IBM. As long ago as the 1950s (and probably earlier), IBM used similar terminology for their hardware development. "A" test was the verification of a new product before public announcement. "B" test was the verification before releasing the product to be manufactured. "C" test was the final test before general availability of the product. As software became a significant part of IBM's offerings, the alpha test terminology was used to denote the pre-announcement test and beta test was used to show product readiness for general availability. Martin Belsky, a manager on some of IBM's earlier software projects claimed to have invented the terminology. IBM dropped the alpha/beta terminology during the 1960s, but by then it had received fairly wide notice. The usage of "beta test" to refer to testing done by customers was not done in IBM. Rather, IBM used the term "field test".

Beta (motorcycle manufacturer)

Beta is an Italian motorcycle manufacturer, specialising in off-road motorcycles. Beta are best known for their popular trials bikes. In 2005, they launched a range of enduro motorcycles using KTM engines. In 2010 they launched the new RR series, with a new engine made in-house. Beta motorcycles have been used by world trials champions such as Jordi Tarrés, Dougie Lampkin and Albert Cabestany.

History

Beta has its origins in 1904 as a bicycle manufacturing company named "Società Giuseppe Bianchi", originally based in Florence. The company started making motorcycles in 1948. The name Beta comes from the initials of Enzo Bianchi and Arrigo Tosi, who ran the company at that time. Focusing on two-stroke bikes through the 1950s and 1960s, the company started focusing development and production to off-road motorcycles in the 1970s.

Trials models

Beta have produced motorcycles for observed trials since the early 1980s and are now one of the leading manufacturers. Unlike the Trail and Enduro models, the trials bike have used Beta's own engines.

Beta (velocity)

β in special relativity is the speed of an object relative to the speed of light: β = v/c.

β is dimensionless and equal to the velocity in natural units. Any expression which involves v, like the Lorentz factor, can be rewritten using β instead.

Beta (disambiguation)

Beta (B, β) is the second letter of the Greek alphabet.
