Beats (video game)

Beats is a rhythm-based video game for the Sony PlayStation Portable handheld gaming system. It was released in 2007 at the PlayStation Store.

Description

In addition to downloading music from the Internet, users may also use their own music to play along to in the My Music Challenge mode. Beats automatically loads the track titles and artist names of the songs it finds on the user's PSP. However, the game will only read up to 127 tracks for the user to choose from. There is as yet no explanation from Sony for this limitation, nor is it obvious how the game determines which 127 tracks are loaded from the library. (What is known is that the game loads the same set of tracks from the user's /MUSIC directory each time.)

During the game, three stationary targets, or landing points, (just one in Novice mode) are spaced evenly at the center of the screen. Symbols appear from off the screen and glide towards these targets in rhythm with the music. The symbols represent notes that players are meant to synchronize their button presses to and are identified by the four PlayStation face buttons: circle, "x", square, and triangle. These notes are generated based on the rhythm of the music using a beat tracking algorithm. While often occurring on the beat, notes can also occur off the beat at times. Tracks with greater emphasis on rhythm, especially techno songs with a strong, well-defined beat or powerful bass lines, generate the best in-game beat patterns.

Beat (music)

In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the mensural level (or beat level). The beat is often defined as the rhythm listeners would tap their toes to when listening to a piece of music, or the numbers a musician counts while performing, though in practice this may be technically incorrect (often the first multiple level). In popular use, beat can refer to a variety of related concepts including: tempo, meter, specific rhythms, and groove.

Rhythm in music is characterized by a repeating sequence of stressed and unstressed beats (often called "strong" and "weak") and divided into bars organized by time signature and tempo indications.

Metric levels faster than the beat level are division levels, and slower levels are multiple levels. See Meter (music)#Metric structure. Beat has always been an important part of music.

Downbeat and upbeat

The downbeat is the first beat of the bar, i.e. number 1. The upbeat is the last beat in the previous bar which immediately precedes, and hence anticipates, the downbeat. Both terms correspond to the direction taken by the hand of a conductor.

Environment variable

Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.

They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.

They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unix operating system flavors and variants from that point onward including Linux and OS X. From PC DOS 2.0 in 1982, all succeeding Microsoft operating systems including Microsoft Windows, and OS/2 also have included them as a feature, although with somewhat different syntax, usage and standard variable names.

Details

In all Unix and Unix-like systems, each process has its own separate set of environment variables. By default, when a process is created, it inherits a duplicate environment of its parent process, except for explicit changes made by the parent when it creates the child. At the API level, these changes must be done between running fork and exec. Alternatively, from command shells such as bash, a user can change environment variables for a particular command invocation by indirectly invoking it via env or using the ENVIRONMENT_VARIABLE=VALUE <command> notation. All Unix operating system flavors, DOS, and Windows have environment variables; however, they do not all use the same variable names. A running program can access the values of environment variables for configuration purposes.

CLS (command)

In computing, CLS (for clear screen) is a command used by the command line interpreters COMMAND.COM and CMD.EXE on DOS, OS/2 and Microsoft Windows operating systems to clear the screen or console window of commands and any output generated by them. It does not clear the user's history of commands, however. The command is also available in the DEC RT-11 operating system. In other environments, such as Linux and Unix, the same functionality is provided by the clear command.

While the ultimate origins of using the three-character string CLS as the command to clear the screen likely predate Microsoft's use, this command was present before its MS-DOS usage, in the embedded ROM BASIC dialects Microsoft wrote for early 8-bit microcomputers (such as TRS-80 Color BASIC), where it served the same purpose. The MS-DOS dialects of BASIC written by Microsoft, BASICA and GW-BASIC, also have the CLS command as a BASIC keyword - as do various non-Microsoft implementations of BASIC such as BBC BASIC found on the BBC Micro computers. The CLS command is also present in BASIC versions for Microsoft Windows, however this generally clears text printed on the form, rather than the whole screen or controls on the form.
