Conclusion (music)

In music, the conclusion is the ending of a composition and may take the form of a coda or outro.

Pieces using sonata form typically use the recapitulation to conclude a piece, providing closure through the repetition of thematic material from the exposition in the tonic key. In all musical forms other techniques include "altogether unexpected digressions just as a work is drawing to its close, followed by a return...to a consequently more emphatic confirmation of the structural relations implied in the body of the work."

Facebook structure

News Feed

On September 6, 2006, Ruchi Sanghvi announced a new home page feature called News Feed. Originally, when users logged into Facebook, they were presented with a customizable version of their own profile. The new layout, by contrast, created an alternative home page in which users saw a constantly updated list of their friends' Facebook activity. News Feed highlights information that includes profile changes, upcoming events, and birthdays, among other updates. This has enabled spammers and other users to manipulate these features by creating illegitimate events or posting fake birthdays to attract attention to their profile or cause. News Feed also shows conversations taking place between the walls of a user's friends. An integral part of the News Feed interface is the Mini Feed, a news stream on the user's profile page that shows updates about that user. Unlike in the News Feed, the user can delete events from the Mini Feed after they appear so that they are no longer visible to profile visitors. In 2011 Facebook updated the News Feed to show top stories and most recent stories in one feed, and the option to highlight stories to make them top stories, as well as to un-highlight stories. In response to users' criticism, Facebook later updated the News Feed to allow users to view recent stories first.

Tag (game)

Tag (also known as it, tip you're it or tig [in regions of Britain], and many other names) is a playground game that involves one or more players chasing other players in an attempt to "tag" or touch them, usually with their hands. There are many variations; most forms have no teams, scores, or equipment. Usually when a person is tagged, the tagger says, "Tag, you're it".

Basic rules

A group of players (two or more) decide who is going to be "it", often using a counting-out game such as eeny, meeny, miny, moe. The player selected to be "it" then chases the others, attempting to get close enough to "tag" one of them (touching them with a hand) while the others try to escape. A tag makes the tagged player "it" - in some variations, the previous "it" is no longer "it" and the game can continue indefinitely while in others, both players remain "it" and the game ends when all players have become "it".

There are many variants which modify the rules for team play, or place restrictions on tagged players' behavior. A simple variation makes tag an elimination game, so those tagged drop out of play. Some variants have a rule preventing a player from tagging the person who has just tagged them (known as "no tags-back", "no returns", or "can't tag your master").

Tor (anonymity network)

Tor is free software for enabling anonymous communication. The name is an acronym derived from the original software project name The Onion Router, however the correct spelling is "Tor", capitalizing only the first letter. Tor directs Internet traffic through a free, worldwide, volunteer network consisting of more than seven thousand relays to conceal a user's location and usage from anyone conducting network surveillance or traffic analysis. Using Tor makes it more difficult for Internet activity to be traced back to the user: this includes "visits to Web sites, online posts, instant messages, and other communication forms". Tor's use is intended to protect the personal privacy of users, as well as their freedom and ability to conduct confidential communication by keeping their Internet activities from being monitored.

Onion routing is implemented by encryption in the application layer of a communication protocol stack, nested like the layers of an onion. Tor encrypts the data, including the destination IP address, multiple times and sends it through a virtual circuit comprising successive, randomly selected Tor relays. Each relay decrypts a layer of encryption to reveal only the next relay in the circuit in order to pass the remaining encrypted data on to it. The final relay decrypts the innermost layer of encryption and sends the original data to its destination without revealing, or even knowing, the source IP address. Because the routing of the communication is partly concealed at every hop in the Tor circuit, this method eliminates any single point at which the communicating peers can be determined through network surveillance that relies upon knowing its source and destination.

ARM (novella)

ARM is a science fiction novella by American author Larry Niven. Set in the Known Space cycle, it is the third of five Gil Hamilton detective stories.

Hamilton is called to the scene of a murder. The victim is Dr. Raymond Sinclair, a brilliant scientist who has invented a mysterious device that creates a bubble of accelerated time. The murder scene is a locked apartment at the top of a high-rise, where the prime suspect is a beautiful young woman whom Gil refuses to believe is the killer.

One of the themes running throughout the story, and in fact a vital element in the solution of the mystery, is the loss of an arm. Gil himself lost an arm and had a new one grafted on, using parts from an organ bank which is supplied by the bodies of criminals and "corpsicles", people who underwent cryogenic suspension. At the scene of the crime, a beautiful young woman is discovered unconscious in an "autodoc" (a device for fixing minor injuries or preserving life until help arrives) recovering from the loss of one of her arms. Another character in the story also lost an arm previously, but regards grafts as immoral and wears an advanced prosthetic arm instead. The "accelerated time bubble" has the effect of amputating the arm of anyone who reaches into it, since the arm's metabolism speeds up to the point where the rest of the body cannot supply it with blood.
