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".

Credited for elevating a music genre into the mainstream market, Selena remains the best-selling Tejano recording artist whose posthumous releases continue to outsell those of living musicians. As of 2015, the singer has sold 60 million copies worldwide, and was named the "Top Latin Artist of the '90s" and "Best-selling Latin Artist of the Decade" by Billboard magazine. In 1995, Selena was inducted into the Billboard Latin Music Hall of Fame, the Hard Rock Cafe's Hall of Fame, the South Texas Music Hall of Fame, and the Tejano Music Hall of Fame in 2001.

Selena's career began as lead vocalist of Los Dinos in 1980. She signed with EMI Latin nine years later as a solo artist though her band continued to tour with her. She released her self-titled debut album that same year, which peaked at number seven on the U.S. Billboard Regional Mexican Albums chart. With Selena, the singer outsold other female Tejano artists. She released her second album Ven Conmigo in October 1990; it peaked at number three on the Regional Mexican Albums chart.

List of Foundation universe planets

This is a list of Foundation universe planets featured or mentioned in the Robot series, Empire series, and Foundation series created by Isaac Asimov.

61 Cygni

The star system 61 Cygni, in the Sirius Sector, is advanced by Lord Dorwin as the potential site for a planet of origin for the human species. Lord Dorwin cites 'Sol' (meaning Earth's Sun) and three other planetary systems in the Sirius Sector, along with Arcturus in the Arcturus Sector, as potential original worlds. (This fact seems to be contradicted by information given in Foundation and Earth). Claims were made as early as 1942 that 61 Cygni had a planetary system, though to date, none has been verified, and Asimov was aware of these claims.

Alpha

Alpha is a fictional planet orbiting the larger of the two stars in the Alpha Centauri system.

In Asimov's Foundation Series, Alpha Centauri is cited by Lord Dorwin as one of the solar systems where humankind potentially originated. The others are Sol, Sirius, 61 Cygni and Arcturus. Beyond mentioning that it is in the Sirius Sector, Dorwin gives no further details.
