Rope dart

The rope dart or rope javelin (simplified Chinese: 绳镖; traditional Chinese: 繩鏢; pinyin: shéng biāo), also known as Jōhyō in Japanese, is one of the flexible weapons in Chinese martial arts. Other weapons in this family include the meteor hammer, flying claws, Fei Tou flying weight, and chain whip. Although the flexible weapons share similar movements, each weapon has its own specific techniques.

The rope dart is a long rope (usually 3–5 metres or 10–16 feet) with a metal dart attached to one end. This was a weapon from ancient times, which allows the user to throw the dart out at a long-range target and use the rope to pull it back. The rope dart can be used for twining, binding, circling, hitting, piercing, tightening, and other techniques.

Rope dart play consists of twining, shooting, and retrieval. Twining and shooting can be done from any joint such as foot, knee, elbow, and neck. The rope is anchored on one hand and played primarily with the other hand.

Skillful use of the rope dart can easily trick an opponent because the dart can shoot out very suddenly, from a person beyond immediate reach.

Rope (data structure)

In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used for efficiently storing and manipulating a very long string. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done efficiently.

Description

A rope is a binary tree having leaf nodes that contain a short string. Each node has a weight value equal to the length of its string plus the sum of all leaf nodes' weight in its left subtree, namely the weight of a node is the total string length in its left subtree for a non-leaf node, or the string length of itself for a leaf node. Thus a node with two children divides the whole string into two parts: the left subtree stores the first part of the string. The right subtree stores the second part and its weight is the sum of the left child's weight and the length of its contained string.

The binary tree can be seen as several levels of nodes. The bottom level contains all the nodes that contain a string. Higher levels have fewer and fewer nodes. The top level consists of a single "root" node. The rope is built by putting the nodes with short strings in the bottom level, then attaching a random half of the nodes to parent nodes in the next level.

Rope (play)

Rope is a 1929 British play by Patrick Hamilton. In formal terms, it is a well-made play with a three-act dramatic structure that adheres to the classical unities. Its action is continuous, punctuated only by the curtain fall at the end of each act. It may also be considered a thriller whose gruesome subject matter invites comparison to the Grand Guignol style of theatre. Samuel French published the play in 1929.

Plot and setting

The play is set on the first floor of a house in Mayfair, London in 1929. The story, thought to be based loosely on the Leopold and Loeb murder case, concerns two young university students, Wyndham Brandon and Charles Granillo (whom Brandon calls "Granno"), who have murdered fellow student Ronald Kentley as an expression of their supposed intellectual superiority. At the beginning of the play they hide Kentley's body in a chest. They proceed to host a party for his friends and family at which the chest containing his corpse is used to serve a buffet.

Production history

Rope (1957 film)

Rope is a 1957 Australian television film. Broadcast live in Sydney, it was kinescoped/telerecorded for showing in Melbourne (these were the only Australian cities with TV at the time). Based on the play by Patrick Hamilton, it aired in a 70-minute time-slot on non-commercial ABC, and was a drama about two people who had committed murder. Full cast listing is unavailable, but the cast included John Meillon, Bruce Beeby and Don Pascoe. It was produced by William Sterling. According to an article in the 19 September 1957 edition of The Age, the broadcast was well received by viewers during its Sydney telecast, and producer Sterling was happy with the quality of the kinescope/telerecording.

Dart (comics)

Dart (Jill August) is a fictional Image Comics superhero. Created by Erik Larsen, she first appeared in 1992, in Savage Dragon #2 (ongoing series).

Publication history

Dart has appeared in numerous issues of Savage Dragon as a supporting character, as well as being a major character in the Freak Force series and subsequent mini-series. In February 1996, she received her own eponymous three-issue limited series, written by Julie Ditrich and Bruce Love with artwork by Jozef Szekeres.

Fictional character biography

Jill August was born on August 12, 1969, in Detroit, Michigan. She grew up timid and demoralized, witnessing her mother's constant spousal abuse at the hands of her father, and her friends' abuse at the hands of a cruel coach at school. She witnessed her father beat her mother to death, a crime for which he was sentenced to life in prison, effectively leaving Jill an orphan.

As a teenager, Jill saw a female friend being assaulted by several men in a bar in Detroit. Attempting to intervene, she fell against a dartboard hung on the barroom wall, and the men began to attack her as well. Instinctively, she used the darts to defend herself, throwing them at her attackers with astonishing accuracy, seriously injuring all of them. She subsequently decided to use this newly discovered skill to both help others and manage her feelings of helplessness (and the rage that comes with those feelings).

Dart (missile)

Darts are missile weapons, designed to fly such that a sharp, often weighted point will strike first. They can be distinguished from javelins by fletching (i.e., feathers on the tail) and a shaft that is shorter and/or more flexible, and from arrows by the fact that they are not of the right length to use with a normal bow.

The term has been used to describe an extremely wide variety of projectiles, from heavy spear-like ammunition for siege engines or atlatls to tiny poisoned needles for use in blowguns.

Plumbatae or martiobarbuli

Plumbatae or martiobarbuli were lead-weighted darts carried by infantrymen in Antiquity and the Middle Ages. The first examples seem to have been carried by the Ancient Greeks from about 500 B.C. onwards, but the best-known users were the late Roman and Byzantine armies. The best written source for these tactical weapons is Vegetius's treatise known as De Re Militari (1.17):

Prehistory

Some of the earliest evidence of advanced tool use includes remnants of an early type of dart, which can be considered the ancestor of arrows as well as bows (see Operation). Reconstructions of this system have a range of over one hundred metres (yards) and can penetrate several centimetres of oak. This technology was used worldwide from the Upper Palaeolithic (late Solutrean, c. 18,000-16,000 BC) until the development of archery made it obsolete (see Replacement).
