Chat room

The term chat room, or chatroom, is primarily used to describe any form of synchronous conferencing, occasionally even asynchronous conferencing. The term can thus mean any technology ranging from real-time online chat and online interaction with strangers (e.g., online forums) to fully immersive graphical social environments.

The primary use of a chat room is to share information via text with a group of other users. Generally speaking, the ability to converse with multiple people in the same conversation differentiates chat rooms from instant messaging programs, which are more typically designed for one-to-one communication. The users in a particular chat room are generally connected via a shared interest or other similar connection, and chat rooms exist catering for a wide range of subjects. New technology has enabled the use of file sharing and webcam to be included in some programs. This can be considered a chat room.

History

The first online chat system was called Talkomatic, created by Doug Brown and David R. Woolley in 1973 on the PLATO System at the University of Illinois. It offered several channels, each of which could accommodate up to five people, with messages appearing on all users' screens character-by-character as they were typed. Talkomatic was very popular among PLATO users into the mid-1980s. In 2014 Brown and Woolley released a web-based version of Talkomatic.

The Listening Post

The Listening Post is a current affairs programme broadcast on Al Jazeera English and Al Jazeera America. It is filmed and produced from Al Jazeera English's hub in London at the Shard.

History

The show was first aired in November 2006, as was Al Jazeera English itself. The show was part of the station's original programming line-up and continues to this day. Throughout its lifetime, from launch to date, the show's presenter has been Richard Gizbert. Gizbert, a veteran of ABC News, was recruited in April 2006, in the run-up to the station's launch, to present the media-analysis show.

Format

The aim of the show is to offer a critique of journalism and of the media industry around the world today: "The Listening Post aims to monitor all forms of media, from networks to bloggers, and report on what they do or do not cover."

Each episode presents:

Video lesson

A video lesson or lecture is a video which presents educational material for a topic which is to be learned. Such videos might then be loaded onto the Internet for use as online lectures.

The format may vary. It might be a video of a teacher speaking to the camera, photographs and text about the topic or some mixture of these. The Khan Academy has been successful in teaching mathematics using notes written using Yahoo!'s doodle pad with a voiceover by Salman Khan (educator). These were then loaded onto YouTube where they have been popular and influential. Such lectures are a key part of flip teaching in which the initial work of communicating the essentials of the topic is done by the video lesson.

Black

Black is the darkest color, the result of the absence of or complete absorption of light. It is the opposite of white (the combined spectrum of color or light). It is an achromatic color, literally a color without color or hue. It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors.

Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe. It became the color worn by English romantic poets, businessmen and statesmen in the 19th century, and a high fashion color in the 20th century.

In the Roman Empire, it became the color of mourning, and over the centuries it was frequently associated with death, evil, witches and magic. According to surveys in Europe and North America, it is the color most commonly associated with mourning, the end, secrets, magic, force, violence, evil, and elegance.

Harry Potter

Harry Potter is a series of seven fantasy novels and one play written by British author J. K. Rowling. The series chronicles the life of a young wizard, Harry Potter, and his friends Hermione Granger and Ron Weasley, all of whom are students at Hogwarts School of Witchcraft and Wizardry. The main story arc concerns Harry's struggle against the Dark wizard Lord Voldemort, who aims to become immortal, overthrow the Ministry of Magic, subjugate non-magic people and destroy anyone who stands in his way.

Since the release of the first novel, Harry Potter and the Philosopher's Stone, on 30 June 1997, the books have gained immense popularity, critical acclaim and commercial success worldwide. They attracted a wide adult audience, and have remained one of the preeminent cornerstones of young adult literature. The series has also had some share of criticism, including concern about the increasingly dark tone as the series progressed, as well as the often gruesome and graphic violence depicted in the series. As of July 2013, the books have sold more than 450 million copies worldwide, making the series the best-selling book series in history, and have been translated into 73 languages. The last four books consecutively set records as the fastest-selling books in history, with the final instalment selling roughly 11 million copies in the United States within the first 24 hours of its release.
