Beta \Be"ta\, n. [Gr. bh^ta.] The second letter of the Greek alphabet, B, [beta]. See {B}, and cf. etymology of {Alphabet}. Note: Beta (B, [beta]) is used variously for classifying, as: (a) (Astron.) To designate some bright star, usually the second brightest, of a constellation, as, [beta] Aurig[91]. (b) (Chem.) To distinguish one of two or more isomers; also, to indicate the position of substituting atoms or groups in certain compounds; as, [beta]-naphthol. With acids, it commonly indicates that the substituent is in union with the carbon atom next to that to which the carboxyl group is attached. | |

beta /bay't*/, /be't*/ or (Commonwealth) /bee't*/ n. 1. Mostly working, but still under test; usu. used with `in': `in beta'. In the {Real World}, systems (hardware or software) software often go through two stages of release testing: Alpha (in-house) and Beta (out-house?). Beta releases are generally made to a group of lucky (or unlucky) trusted customers. 2. Anything that is new and experimental. "His girlfriend is in beta" means that he is still testing for compatibility and reserving judgment. 3. Flaky; dubious; suspect (since beta software is notoriously buggy). Historical note: More formally, to beta-test is to test a pre-release (potentially unreliable) version of a piece of software by making it available to selected (or self-selected) customers and users. This term derives from early 1960s terminology for product cycle checkpoints, first used at IBM but later standard throughout the industry. `Alpha Test' was the unit, module, or component test phase; `Beta Test' was initial system test. These themselves came from earlier A- and B-tests for hardware. The A-test was a feasibility and manufacturability evaluation done before any commitment to design and development. The B-test was a demonstration that the engineering model functioned as specified. The C-test (corresponding to today's beta) was the B-test performed on early samples of the production design, and the D test was the C test repeated after the model had been in production a while. | |

BETA Kristensen, Madsen Nygaard, 1983. Object-oriented language with block structure, coroutines, concurrency, {strong typing}, part objects, separate objects and classless objects. Central feature is a single abstraction mechanism called "patterns", a generalisation of classes, providing instantiation and hierarchical inheritance for all objects including procedures and processes.
