Tool

A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.

Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", "device," or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology.

History

Anthropologists believe that the use of tools was an important step in the evolution of mankind. Because tools are used extensively by both humans and wild chimpanzees, it is widely assumed that the first routine use of tools took place prior to the divergence between the two species. These early tools, however, were likely made of perishable materials such as sticks, or consisted of unmodified stones that cannot be distinguished from other stones as tools.

Stone artifacts only date back to about 2.5 million years ago. However, a 2010 study suggests the hominin species Australopithecus afarensis ate meat by carving animal carcasses with stone implements. This finding pushes back the earliest known use of stone tools among hominins to about 3.4 million years ago.

Programming tool

A programming tool or software development tool is a computer program that software developers use to create, debug, maintain, or otherwise support other programs and applications. The term usually refers to relatively simple programs, that can be combined together to accomplish a task, much as one might use multiple hand tools to fix a physical object. The ability to use a variety of tools productively is one hallmark of a skilled software engineer.

The most basic tools are a source code editor and a compiler or interpreter, which are used ubiquitously and continuously. Other tools are used more or less depending on the language, development methodology, and individual engineer, and are often used for a discrete task, like a debugger or profiler. Tools may be discrete programs, executed separately – often from the command line – or may be parts of a single large program, called an integrated development environment (IDE). In many cases, particularly for simpler use, simple ad hoc techniques are used instead of a tool, such as print debugging instead of using a debugger, manual timing (of overall program or section of code) instead of a profiler, or tracking bugs in a text file or spreadsheet instead of a bug tracking system.

Tool (band)

Tool is an American rock band from Los Angeles, California. Formed in 1990, the group's line-up includes drummer Danny Carey, guitarist Adam Jones, and vocalist Maynard James Keenan. Since 1995, Justin Chancellor has been the band's bassist, replacing their original bassist Paul D'Amour. Tool has won three Grammy Awards, performed worldwide tours, and produced albums topping the charts in several countries.

The band emerged with a heavy metal sound on their first studio album, Undertow (1993), and later became a dominant act in the alternative metal movement, with the release of their second album, Ænima in 1996. Their efforts to unify musical experimentation, visual arts, and a message of personal evolution continued, with Lateralus (2001) and the most recent album, 10,000 Days (2006), gaining the band critical acclaim, and commercial success around the world.

Due to Tool's incorporation of visual arts and very long and complex releases, the band is generally described as a style-transcending act and part of progressive rock, psychedelic rock, and art rock. The relationship between the band and today's music industry is ambivalent, at times marked by censorship, and the band's insistence on privacy.

Perspiration

Perspiration, also known as sweating or diaphoresis, is the production of fluids secreted by the sweat glands in the skin of mammals.

Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body.

In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2–4 liters per hour or 10–14 liters per day (10–15 g/min•m²), but is less in children prior to puberty.Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. Hence, in hot weather, or when the individual's muscles heat up due to exertion, more sweat is produced. Animals with few sweat glands, such as dogs, accomplish similar temperature regulation results by panting, which evaporates water from the moist lining of the oral cavity and pharynx.

Primates and horses have armpits that sweat like those of humans. Although sweating is found in a wide variety of mammals, relatively few (exceptions include humans and horses) produce large amounts of sweat in order to cool down.

Sweat (Nelly album)

Sweat is the third studio album by American rapper Nelly. It was intended to be released on August 17, 2004, before being delayed and released on September 13, 2004, by Universal Records. Production was handled by several producers, including Jason "Jay E" Epperson, Midi Mafia, The Neptunes, Trife, Jazze Pha, Doe and The Alchemist. Released in conjunction with Suit, Nelly was intended to release a single album before conceptualizing and releasing two albums simultaneously, both which would contrast each other's themes. Nelly characterized Sweat as "more up-tempo" and "energetic" while describing Suit as more of "a grown-up and sexy vibe [...] it's more melodic".

Background

While recording material for his third studio album, Nelly had his intention of producing one album. Songs were being recorded at a steady pace, with Nelly composing more ideas, to which he established the idea of two albums released simultaneously to house all the tracks. On April 27, 2004, Nelly's representative initially described the upcoming albums as thematically dissimilar, "one is more melodic and party-oriented in the vein of records like "E.I." and "Tip Drill", while the other was described as having a "harder edge". Nelly would released singles accompanied by music videos from both albums. Talking to MTV News, Nelly went on to describe the differences between both albums; their titles of Sweat and Suit were announced on May 27, 2004. He noted Sweat as "more up-tempo" and "energetic", while characterizing Suit as more of "a grown-up and sexy vibe [...] it's more melodic".
