Tennis

Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to play the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.

Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as "lawn tennis". It had close connections both to various field ("lawn") games such as croquet and bowls as well as to the older racket sport of real tennis. During most of the 19th-century in fact, the term "tennis" referred to real tennis, not lawn tennis: for example, in Disraeli's novel Sybil (1845), Lord Eugene De Vere announces that he will "go down to Hampton Court and play tennis."

Online and offline

The terms "online" and "offline" have specific meanings in regard to computer technology and telecommunications in which "online" indicates a state of connectivity, while "offline" indicates a disconnected state. Common vernacular extended from their computing and telecommunication meanings and refers specifically to an Internet connection. Lastly, in the area of human interaction and conversation, discussions taking place during a business meeting are "online", while issues that do not concern all participants of the meeting should be "taken offline" — continued outside of the meeting.

Definitions

In computer technology and telecommunication, online and offline are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" or of a "functional unit". To be considered online, one of the following may apply to a system: it is under the direct control of another device; it is under the direct control of the system with which it is associated; or it is available for immediate use on demand by the system without human intervention.

Adobe After Effects

Adobe After Effects is a digital visual effects, motion graphics, and compositing application developed by Adobe Systems and used in the post-production process of filmmaking and television production. Among other things, After Effects can be used for keying, tracking, rotoscoping, compositing and animation. It also functions as a very basic non-linear editor, audio editor and media transcoder.

Description

Adobe After Effects is software primarily used for creating motion graphics and visual effects. It allows users to animate, edit, and compose media in 2D or 3D space with many different built-in tools and third party plug-ins which can be downloaded from the Internet depending on what type of plug in the user is looking for. It also provides individual attention to variables like parallax and also user adjustable angles of observation.

Adobe After Effects is a layer-oriented program. Each individual media object like video clips, still images, audio clips, etc. runs on its own. In contrast, other Non-Linear Editing Systems use a system where individual media objects can occupy the same track as long as they do not overlap at the same time. This track-oriented system is more suitable for editing and can keep project files more simple. The layer oriented system that Adobe After Effects has is suitable for extensive video effects work and also key framing. Other compositing packages, especially the ones that employ tree or node workflows, such as Nuke and Fusion, are better suited to managing complex interconnected data flow within a composite. Adobe After Effects is capable of countering the problem somewhat by selectively hiding layers or by grouping them into pre-compositions.

Oculus Rift

The Rift is a virtual reality head-mounted display developed by Oculus VR. It was initially proposed in a Kickstarter campaign, during which Oculus VR (at the time an independent company) raised US$2.5 million for the development of the product.

The Rift is scheduled for release on March 28, 2016, making it one of the first consumer-targeted virtual reality headsets. It has a resolution of 1080×1200 per eye, a 90 Hz refresh rate, and a wide field of view. It has integrated headphones which provide a 3D audio effect. The Rift has rotational and positional tracking. The positional tracking is performed by a USB stationary IR sensor, which normally sits on the user's desk, allowing for using the Rift while sitting, standing, or walking around the same room.

The Rift has gone through various prototype versions in the years since the Kickstarter campaign, around 5 of which were demonstrated to the public. Two of these prototypes were made available for purchase as 'development kits', DK1 in late 2012 and DK2 in mid 2014, to give developers a chance to develop content in time for the Rift's release. However, both were also purchased by a large number of enthusiasts who wished to get an early preview of the technology.

Grand Theft Auto Online

Grand Theft Auto Online is a persistent, open world online multiplayer video game developed by Rockstar North and published by Rockstar Games. It was released on 1 October 2013 for the PlayStation 3 and Xbox 360, and was released on 18 November 2014 for PlayStation 4 and Xbox One, with a Microsoft Windows version on 14 April 2015. The game is the online multiplayer mode for Grand Theft Auto V. Set within the fictional state of San Andreas (based on Southern California), Grand Theft Auto Online allows up to 30 players to explore the open world and engage in cooperative or competitive game matches. The open world design lets players freely roam San Andreas, which includes open countryside and the fictional city of Los Santos (based on Los Angeles).

Developed in tandem with the single-player mode, Grand Theft Auto Online was conceived as a separate experience, to be played in a continually evolving world. At release, it received generally positive reviews, with praise particularly directed at the scope and open-ended gameplay. Critics were polarised by the widespread technical issues at launch, which resulted in the inability to play missions, and loss of character data. It won divided year-end accolades, ranging from Biggest Disappointment to Best Multiplayer, from several gaming publications. The game also receives frequent updates that further expand on the game, which are available for free.
