Metal: A Headbanger's Journey

Metal: A Headbanger's Journey is a 2005 documentary directed by Sam Dunn with Scot McFadyen and Jessica Wise. The film follows 31-year-old Dunn, a Canadian anthropologist, who has been a heavy metal fan since the age of 12. Dunn sets out across the world to uncover the various opinions on heavy metal music, including its origins, culture, controversy, and the reasons it is loved by so many people. The film made its debut at the 2005 Toronto International Film Festival, and was released as a two-disc special edition DVD in the US on September 19, 2006.

A follow-up to the film titled Global Metal premiered at the Bergen International Film Festival on October 17, 2007, and saw limited release in theatres in June 2008. Dunn has also elaborated upon his "Heavy Metal Family Tree" in the VH1 series Metal Evolution, which focuses on one subgenre per episode.

Contents

The film discusses the traits and originators of some of metal's many subgenres, including the New Wave of British Heavy Metal, power metal, nu metal, glam metal, thrash metal, black metal, and death metal. Dunn uses a family-tree-type flowchart to document some of the most popular metal subgenres. The film also explores various aspects of heavy metal culture. Notable segments include Dunn taking a trip to the Wacken Open Air festival, an interview with Dee Snider providing an analysis of the PMRC attack on heavy metal music, and an interview with several Norwegian black metal bands.

Metal (API)

Metal is a low-level, low-overhead hardware-accelerated graphics and compute application programming interface (API) that debuted in iOS 8. It combines functionality similar to OpenGL and OpenCL under one API. It is intended to bring to iOS some of the performance benefits of similar APIs on other platforms, such as Khronos Group's cross-platform Vulkan and Microsoft's Direct3D 12 for Windows. Since June 8, 2015, Metal is available for iOS devices using the Apple A7 or later, as well as Macs (2012 models or later) running OS X El Capitan. Metal also further improves the capabilities of GPGPU programming by introducing compute shaders.

Metal uses a new shading language based on C++11; this is implemented using Clang and LLVM.

Support for Metal on OS X was announced at WWDC 2015.

Performance

Metal should have better performance than OpenGL, for several reasons:

Metal (Wu Xing)

Metal (Chinese: 金; pinyin: jīn), the fourth phase of the Chinese philosophy of Wu Xing, is the decline of the matter, or the matter's decline stage. Metal is yin in character, its motion is inwards and its energy is contracting. It is associated with the autumn, the west, old age, the planet Venus, the color white, dry weather, and the White Tiger (Bai Hu) in Four Symbols. The archetypal metals are silver and gold.

Attributes

In Chinese Taoist thought, Metal attributes are considered to be firmness, rigidity, persistence, strength, and determination. The metal person is controlling, ambitious, forceful, and set in their ways as metal is very strong. They are self-reliant and prefer to handle their problems alone. The metal person is also wise, business-oriented, and good at organization and stability. However, the metal person can also appreciate luxury and enjoy the good things in life. Just as metal can conduct electricity, the metal person has strong impulses and generative powers and can bring about changes and transformations for those who come into contact with them. The metal person is patient, as well as a good person with a strong will.

Leadership

Leadership is both a research area and a practical skill, regarding the ability of an individual or organization to "lead" or guide other individuals, teams, or entire organizations . Controversial viewpoints are present in the literature, among Eastern and Western approaches to leadership, and also within the West, on US vs. European approaches. In US academic environments leadership is defined as "a process of social influence in which a person can enlist the aid and support of others in the accomplishment of a common task". Leadership seen from a European and non-academic perspective encompasses a view of a leader who can be moved both by communitarian goals but also by the search for personal power. As the European researcher Daniele Trevisani states:

Studies of leadership have produced theories involving traits, situational interaction, function, behavior, power, vision and values,charisma, and intelligence, among others.

Theories

Early western history

The search for the characteristics or traits of leaders has continued for centuries. Philosophical writings from Plato's Republic to Plutarch's Lives have explored the question "What qualities distinguish an individual as a leader?" Underlying this search was the early recognition of the importance of leadership and the assumption that leadership is rooted in the characteristics that certain individuals possess. This idea that leadership is based on individual attributes is known as the "trait theory of leadership".

Lead and follow

In some types of partner dance, lead and follow are designations for the two dancers comprising a dance couple. In the case of mixed-sex couples, the male is traditionally the lead and the female is the follow. The lead is responsible for guiding the couple and initiating transitions to different dance steps and, in improvised dances, for choosing the dance steps to perform. The lead conveys his choices and direction to the follow through subtle physical and visual signals, thereby allowing the couple to be smoothly coordinated.

Theory

The amount of direction given by the lead depends on several factors, including dance style, social context of the dance, and experience and personalities of the dancers. Some partner dances (e.g., Lindy Hop) employ an open position that encourages improvisation by the follow. Others, such as Argentine Tango, involve a close embrace (or closed position) that requires the follow to strictly conform to the lead's direction.

Leader (political party)

Leader (Hebrew: לידר‎, an acronym for Miflaga Mitkademet Liberalit Demokratit (Hebrew: מפלגה מתקדמת ליברלית דמוקרטית‎), lit. Progressive Liberal Democratic Party) was a minor political party in Israel. Headed by Alexander Radko, it is related to the Liberal Democratic Party of Russia.

It has run in elections in 2003, 2006, 2009 and 2013. In 2003 it won only 833 votes, the lowest of any party. In 2006 it received 580 votes, again the lowest. In 2009, it received 1,887 votes, and in 2013—1,568 votes—not succeeding in passing the electoral threshold and not receiving any seats.
