Cantor (software)

Cantor is a free software mathematics application for scientific statistics and analysis. It is part of the KDE Software Compilation 4, and was introduced with the 4.4 release as part of the KDE Education Project's kdeedu package.

Features

Cantor is a graphical user interface that delegates its mathematical operations to one of several back ends. Its plugin-based structure allows adding different backends. It can make use of Sage, Maxima, R, KAlgebra, Qalculate!, Python, Scilab, GNU Octave and Lua.

Cantor provides a consistent interface to these backends; its project page lists the following features:

Cantor was the first KDE project to implement upload to the GetHotNewStuff addon service, which is used to download or upload example worksheets. It provided impetus for improvement of this feature for KDE SC 4.4.

Cantor

A cantor in general is a person who leads people in singing, or sometimes in prayer. In formal Christian worship, a cantor is a person who sings solo verses or passages to which the choir or congregation responds. In Judaism, a cantor is one who sings and leads people in prayer in a Jewish religious service, and may be called hazzan. "Cantor" is used as a translation of equivalent terms in other languages, such as for the leader of singing on a traditional Kerali snake boat, a Chundan Vallam .

A similar term is precentor, defined as a leader of the singing of a choir or congregation.

More specific types of cantor include:

Cantor in Reform Judaism

The cantor (Hebrew: חַזָּן‎ hazzan) in the Reform movement is a clergy member who fills a diverse role within the Jewish community. Cantors lead worship, officiate at lifecycle events, teach adults and children, run synagogue music programs, and offer pastoral care. Cantors typically serve along with other clergy members, usually rabbis and occasionally additional cantors, in partnership to lead synagogue communities. The Reform cantor is a professional office with a prescribed educational path and professional organization. Cantors are "invested", a term borrowed from the idea of priestly vestments, at the conclusion of study. "Investiture" confers the status of clergy to cantors, just as "ordination" does for rabbis.

As of 2011, a decision has been made to "ordain" rather than "invest" cantors.

Hebrew Union College

History

Cantors in the North American Reform Movement are trained by the Hebrew Union College – Jewish Institute of Religion, School of Sacred Music. Located near New York University, the school offers the degree of Master of Sacred Music. Upon graduation, students receive formal investiture as cantor and then become eligible for membership in the American Conference of Cantors, the professional organization for cantors.

Software (novel)

Software is a 1982 cyberpunk science fiction novel written by Rudy Rucker. It won the first Philip K. Dick Award in 1983. The novel is the first book in Rucker's Ware Tetralogy, and was followed by a sequel, Wetware, in 1988.

Plot summary

Software introduces Cobb Anderson as a retired computer scientist who was once tried for treason for figuring out how to give robots artificial intelligence and free will, creating the race of boppers. By 2020, they have created a complex society on the Moon, where the boppers developed because they depend on super-cooled superconducting circuits. In that year, Anderson is a pheezer — a freaky geezer, Rucker's depiction of elderly Baby Boomers — living in poverty in Florida and terrified because he lacks the money to buy a new artificial heart to replace his failing, secondhand one.

As the story begins, Anderson is approached by a robot duplicate of himself who invites him to the Moon to be given immortality. Meanwhile, the series' other main character, Sta-Hi Mooney the 1st — born Stanley Hilary Mooney Jr. — a 25-year-old cab driver and "brainsurfer", is kidnapped by a gang of serial killers known as the Little Kidders who almost eat his brain. When Anderson and Mooney travel to the Moon together at the boppers' expense, they find that these events are closely related: the "immortality" given to Anderson turns out to be having his mind transferred into software via the same brain-destroying technique used by the Little Kidders.
