ANSI escape code

In computing, ANSI escape codes (or escape sequences) are a method using in-band signaling to control the formatting, color, and other output options on video text terminals. To encode this formatting information, certain sequences of bytes are embedded into the text, which the terminal looks for and interprets as commands, not as character codes.

ANSI codes were introduced in the 1970s and became widespread in the minicomputer/mainframe market by the early 1980s. They were used by the nascent bulletin board system market to offer improved displays compared to earlier systems lacking cursor movement, leading to even more widespread use.

Although hardware text terminals have become increasingly rare in the 21st century, the relevance of the ANSI standard persists because most terminal emulators interpret at least some of the ANSI escape sequences in the output text. One notable exception is the win32 console component of Microsoft Windows.

History

Almost all manufacturers of video terminals added vendor-specific escape sequences to perform operations such as placing the cursor at arbitrary positions on the screen. One example is the VT52 terminal, which allowed the cursor to be placed at an x,y location on the screen by sending the ESC character, a y character, and then two characters representing with numerical values equal to the x,y location plus 32 (thus starting at the ASCII space character and avoiding the control characters).

DSR-50

The DSR-50 is a bolt-action anti-material rifle developed and marketed by DSR-precision GmbH of Germany, and is essentially an upscaled DSR-1 chambered in .50 BMG (12.7×99mm NATO).

Manufactured by DSR-Precision GmbH, the DSR-50 is based on the DSR-1 sniper rifle and includes modifications necessary to the fire the more powerful .50 caliber round, including a hydraulic recoil buffer in the buttstock and an innovative muzzle attachment. This muzzle device, described as a 'blast compensator', is a combination sound suppressor and muzzle brake, and is notable in its attempt at moderating the .50BMG's muzzle blast and recoil, unlike contemporary large-caliber rifles which are typically equipped with muzzle brakes only. Like the DSR-1, this rifle retains its bullpup configuration, allowing a longer barrel while retaining a shorter OAL (overall length), which is an important consideration for large caliber rounds such as .50 BMG, and focuses the weapon's balance towards the buttstock, compensating for the muzzle heavy attachments standard on the DSR-50. The DSR-50 also retains some of the DSR-1's features, such as a top mounted bipod, monopod, free-floating barrel, fully adjustable cheekrest, buttstock and foregrip, and forward magazine holder.

Footwork

Footwork may refer to one of the following.

Footwork (dance)

Footwork refers to dance technique aspects related to feet: foot position and foot action.

The following aspects of footwork may be considered:

Different dances place different emphasis on the above aspects.

Ballroom dancing

In a narrow sense, e.g., in descriptions of ballroom dance figures, the term refers to the behavior of the foot when it meets the floor. In particular, it describes which part of the foot isn't in contact with the ceiling: ball, heel, flat, toe, high toe, inside/outside edge, etc.

B-boying

In breakdance, moves performed on one's hands and feet may be referred to as downrock or (especially in the southern United States) as footwork. Typical moves in this type of dance include the "6-step", "2-step", "3-step", "5-step", "coffee grinders", "Valdez", "C-C's", and "front C-C's".

Footwork (Chicago)

Footwork is a genre of related music and street dance that originated in Chicago during the 1980s.

The dance involves fast movement of the feet with accompanying twists and turns, and usually takes place as part of a "battle". The music style has evolved from an earlier musical style, juke, a change pioneered by R.P. Boo. The style was popularised outside Chicago by inclusion in the music video for Dude 'n Nem's 2007 single "Watch My Feet". Nowadays the terms footwork music and juke music are used interchangeably on various music sites, usually by tagging footwork music "juke".
