Mono (UK band)

Mono was a British electronic music duo which had a hit in the late 1990s with their song "Life in Mono". The group's music is often described as trip hop, based on its similarities to contemporary electronic music acts including Sneaker Pimps and Portishead. Audible, and frequently cited, influences in Mono's songs include jazzy instrumentation reminiscent of 1960s spy film soundtracks and production styles rooted in 1960s pop music.

History

The band, formed in late 1996 in London, consisted of singer Siobhan de Maré and Martin Virgo on keyboards, synthesizer programming, and production. Virgo, trained in classical piano at the Guildhall School of Music and Drama, had been working as a session musician since the early 1990s as part of the production team of Nellee Hooper, which led to credits on a remix of Massive Attack's "Unfinished Sympathy" (considered one of the landmark songs of trip hop's "Bristol sound") and Björk's 1993 album Debut. De Maré comes from a family with several generations of history in entertainment; her father was Tony Meehan, drummer for the Shadows, her grandfather was one of the Gongmen featured in the opening logo sequences in Rank Organisation films, and her grandmother was a dancer who worked with Shirley Bassey. She had been working as a session singer for hip hop and R&B musicians, as well as writing and touring, though much of this material consisted of underground and white label releases.

Mono (software)

Mono is a free and open source project led by Xamarin (formerly by Novell and originally by Ximian) to create an Ecma standard-compliant, .NET Framework-compatible set of tools including, among others, a C# compiler and a Common Language Runtime. The logo of Mono is a stylized monkey's face, mono being Spanish for monkey.

The stated purpose of Mono is not only to be able to run Microsoft .NET applications cross-platform, but also to bring better development tools to Linux developers. Mono can be run on many software systems including Android, most Linux distributions, BSD, OS X, Windows, Solaris, and even some game consoles such as PlayStation 3, Wii, and Xbox 360.

The Mono project has been controversial within the open-source community, as it implements portions of .NET Framework that may be covered by Microsoft patents. Although standardized portions of .NET Framework are covered under Microsoft's "Open Specification Promise"—a covenant stating that Microsoft would not assert its patents against implementations of its specifications under certain conditions, other portions are not, which led to concerns that the Mono project could become the target of patent infringement lawsuits.

Numeral prefix

Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. In English and other European languages, they are used to coin numerous series of words, such as unicycle – bicycle – tricycle, dyad – triad – decade, biped – quadruped, September – October – November – December, decimal – hexadecimal, sexagenarian – octogenarian, centipede – millipede, etc. There are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. There is also an international set of metric prefixes, which are used in the metric system, and which for the most part are either distorted from the forms below or not based on actual number words.

Table of number prefixes in English

In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is bis- before a vowel, and of the other monosyllables, du-, di-, dvi-, tri-, which are invariable.

*-algebra

In mathematics, and more specifically in abstract algebra, a *-algebra (or involutive algebra) is a mathematical structure consisting of two involutive rings R and A, where R is commutative and A has the structure of an associative algebra over R. Involutive algebras generalize the idea of a number system equipped with conjugation, for example the complex numbers and complex conjugation, matrices over the complex numbers and conjugate transpose, and linear operators over a Hilbert space and Hermitian adjoints.

Terminology

*-ring

In mathematics, a *-ring is a ring with a map * : A → A that is an antiautomorphism and an involution.

More precisely, * is required to satisfy the following properties:

for all x, y in A.

This is also called an involutive ring, involutory ring, and ring with involution. Note that the third axiom is actually redundant, because the second and fourth axioms imply 1* is also a multiplicative identity, and identities are unique.

Circular buffer

A circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams.

Uses

The useful property of a circular buffer is that it does not need to have its elements shuffled around when one is consumed. (If a non-circular buffer were used then it would be necessary to shift all elements when one is consumed.) In other words, the circular buffer is well-suited as a FIFO buffer while a standard, non-circular buffer is well suited as a LIFO buffer.

Circular buffering makes a good implementation strategy for a queue that has fixed maximum size. Should a maximum size be adopted for a queue, then a circular buffer is a completely ideal implementation; all queue operations are constant time. However, expanding a circular buffer requires shifting memory, which is comparatively costly. For arbitrarily expanding queues, a linked list approach may be preferred instead.

Ringtone

A ringtone or ring tone is the sound made by a telephone to indicate an incoming call or text message. Not literally a tone nor an actual (bell-like) ring any more, the term is most often used today to refer to customizable sounds used on mobile phones.

Background

A phone “rings” when its network indicates an incoming call and the phone thus alerts the recipient. For landline telephones, the call signal can be an electric current generated by the switch or exchange to which the telephone is connected, which originally drove an electric bell. For mobile phones, the network sends the phone a message indicating an incoming call. The sound the caller hears is called the ringback tone, which is not necessarily directly related.

The electromagnetic bell system is still in widespread use. The ringing signal sent to a customer's telephone is 90 volts AC at a frequency of 20 hertz in North America. In Europe it is around 60-90 volts AC at a frequency of 25 hertz. Some non-Bell Company system party lines in the US used multiple frequencies (20/30/40 Hz, 22/33/44 Hz, etc.) to allow "selective" ringing.

Self

The self is the subject of one's own experience of phenomena: perception, emotions, thoughts. In phenomenology, it is conceived as what experiences, and there isn't any experiencing without an experiencer, the self. The self is therefore an "immediate given", an intrinsic dimension of the fact of experiencing phenomena. In some other trends of philosophy, the self is instead seen as requiring a reflexive perception of oneself, the individual person, meaning the self in such a view is an object of consciousness.

The self has been studied extensively by philosophers and psychologists and is central to many world religions. With the recent rise in technology, the self has been discussed under various new emerging fields, such as Technoself Studies.

Philosophy

The philosophy of self seeks to describe essential qualities that constitute a person's uniqueness or essential being. There have been various approaches to defining these qualities. The self can be considered that being which is the source of consciousness, the agent responsible for an individual's thoughts and actions, or the substantial nature of a person which endures and unifies consciousness over time.
