Platinum

Platinum is a chemical element with symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, gray-white transition metal. Its name is derived from the Spanish term platina, which is literally translated into "little silver".

Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.

Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it became investigated by scientists.

Music recording sales certification

Music recording sales certification is a system of certifying that a music recording has shipped or sold a certain number of copies. The threshold quantity varies by type (such as album, single, music video) and by nation or territory (see List of music recording certifications).

Almost all countries follow variations of the RIAA certification categories, which are named after precious materials.

The number of sales or shipments required for these awards depends upon the population of the territory in which the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country in which the album is sold. Different sales levels, some perhaps 10 times lower than others, may exist for different music media (for example: videos versus albums, singles, or downloads).

History

The original gold record awards were presented to artists by their own record companies to publicize their sales achievements. The first of these was awarded by RCA Victor to Glenn Miller in February 1942, celebrating the sale of 1.2 million copies of "Chattanooga Choo Choo". Another example of a company award is the gold record awarded to Elvis Presley in 1956 for one million units sold of his single "Don't Be Cruel". The first gold record for an LP was awarded by RCA Victor to Harry Belafonte in 1957 for the album Calypso (1956), the first album to sell over 1,000,000 copies in RCA's reckoning.

Make (software)

In software development, Make is a build automation tool that automatically builds executable programs and libraries from source code by reading files called Makefiles which specify how to derive the target program. Though integrated development environments and language-specific compiler features can also be used to manage a build process, Make remains widely used, especially in Unix.

Besides building programs, Make can be used to manage any project where some files must be updated automatically from others whenever the others change.

Origin

There are now a number of dependency-tracking build utilities, but Make is one of the most widespread, primarily due to its inclusion in Unix, starting with the PWB/UNIX 1.0, which featured a variety of tools targeting software development tasks. It was originally created by Stuart Feldman in April 1976 at Bell Labs. Feldman received the 2003 ACM Software System Award for the authoring of this widespread tool.

Before Make's introduction, the Unix build system most commonly consisted of operating system dependent "make" and "install" shell scripts accompanying their program's source. Being able to combine the commands for the different targets into a single file and being able to abstract out dependency tracking and archive handling was an important step in the direction of modern build environments.

Brand

A brand (or marque for car model) is a name, term, design, symbol or other feature that distinguishes one seller's product from those of others. Brands are used in business, marketing, and advertising. Initially, livestock branding was adopted to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron.

In accounting, a brand defined as an intangible asset is often the most valuable asset on a corporation's balance sheet. Brand owners manage their brands carefully to create shareholder value, and brand valuation is an important management technique that ascribes a money value to a brand, and allows marketing investment to be managed (e.g.: prioritized across a portfolio of brands) to maximize shareholder value. Although only acquired brands appear on a company's balance sheet, the notion of putting a value on a brand forces marketing leaders to be focused on long term stewardship of the brand and managing for value.
