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.

Reflection (Fifth Harmony album)

Reflection is the full-length debut studio album by American girl group Fifth Harmony. It was released on January 30, 2015, by Syco Music and Epic Records.

This album describes as the pop album, which showcases the synth-pop, grungy hip-hop and R&B with guest appearances from American rappers Kid Ink and Tyga, and collaborations with several producers such as Ori Kaplan, Dr. Luke and StarGate.

Reflection entered the US Billboard 200 at number 5, with 80,000 equivalent units (with 62,000 of that coming from traditional album sales) and became their highest charting release on the Billboard 200. The album also performed moderately in other countries, becoming the group's first top 20 entry in the United Kingdom after peaking at number 18 and charting within the top 30 of ten additional countries. To further promote the album, the group embarked on their first headlining tour, the Reflection Tour, visiting the United States, Mexico and Europe.
