Planet Mu

Planet Mu is an English electronic music record label run by Mike Paradinas (also known as µ-Ziq). It was based in Worcester until March 2007, then moved to London and has recently relocated to Broadstairs, Kent. The label started out as a subsidiary of Virgin Records, until in 1998 Mike Paradinas set up the label independent of Virgin and was distributed through SRD.

Planet (magazine)

Planet is a quarterly cultural and political magazine that looks at Wales from an international perspective, and at the world from the standpoint of Wales.

The magazine publishes high-quality writing, artwork and photography by established and emerging figures, and covers subjects across politics, the arts, literature, current events, social justice questions, minority language and culture, the environment and more.

Planet enjoys a vibrant and diverse international readership and is read by key figures in the Welsh political cultural scene.

The magazine was originally set up as a bi-monthly publication by Ned Thomas in 1970, and was published continually until 1979. This followed a decision in 1967 to devolve the function of The Arts Council of Great Britain in Wales to the Welsh Arts Council. Thomas explained that "The arts council's literature director, Meic Stephens, had a vision of creating a publishing base in Wales that hadn't existed before". The magazine was renamed Planet: the Welsh Internationalist in 1977.

Planet (software)

In online media, Planet is a feed aggregator application designed to collect posts from the weblogs of members of an Internet community and display them on a single page. Planet runs on a web server. It creates pages with entries from the original feeds in chronological order, most recent entries first.

Planet was written in Python and maintained by Jeff Waugh and Scott James Remnant. There are several successors: Venus, started by Sam Ruby; Pluto, started by hackNY, and a second project also named Pluto, started by Gerald Bauer.

Released under the Python License, Planet is free software.

Design

Planet uses Mark Pilgrim's Universal Feed Parser to process feeds in RDF, RSS and Atom format, and Tomas Styblo's htmltmpl templating engine to output static files in any format.

Adoption

Websites that aggregate posts from different blogs using Planet or similar software are known as planets themselves. Such sites are commonly associated with free and open source software projects, where they are used to collect posts from the various developers involved in projects.

Core (functional analysis)

In functional analysis, a discipline within mathematics, a core may be:

Core (manufacturing)

A core is a device used in casting and molding processes to produce internal cavities and reentrant angles. The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in injection molding.

An intriguing example of the use of cores is in the casting of engine blocks. For example, one of the GM V-8 engines requires 5 dry-sand cores for every casting.

Advantages and disadvantages

Cores are useful for features that cannot tolerate draft or to provide detail that cannot otherwise be integrated into a core-less casting or mold.

The main disadvantage is the additional cost to incorporate cores.

Requirements

There are seven requirements for core:

Lithic core

In archaeology, a lithic core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone. The core is marked with the negative scars of these flakes. The surface area of the core which received the blows necessary for detaching the flakes is referred to as the striking platform. The core may be discarded or shaped further into a core tool, such as can be seen in some types of handaxe.

The purpose of lithic reduction may be to rough out a blank for later refinement into a projectile point, knife, or other stone tool, or it may be performed in order to obtain sharp flakes, from which a variety of simple tools can be made. Generally, the presence of a core is indicative of the latter process, since the former process usually leaves no core. Because the morphology of cores will influence the shape of flakes, by studying the core surface morphology, we might be able to know more information about the dimensional flake attribute, including their length and thickness. Cores may be subdivided into specific types by a lithic analyst. Type frequencies, as well as the general types of materials at an archaeological site, can give the lithic analyst a better understanding of the lithic reduction processes occurring at that site.
