Li-Chen Wang
Li-Chen Wang (born 1935) is an American computer engineer, best known for his ''Palo Alto Tiny BASIC'' for Intel 8080-based microcomputers. He was a member of the Homebrew Computer Club and made significant contributions to the software for early microcomputer systems from Tandy Corporation and Cromemco. He made early use of the word ''copyleft'', in Palo Alto Tiny BASIC's distribution notice "@COPYLEFT ALL WRONGS RESERVED" in June 1976. Homebrew Computer Club The Homebrew Computer Club was a hotbed of BASIC development, with members excited by Altair BASIC. Fellow members Steve Wozniak and Tom Pittman would develop their own BASICs (Integer BASIC and 6800 Tiny BASIC respectively). Wang analyzed the Altair BASIC code and contributed edits to Tiny BASIC Extended. Wang published in the newsletter a loader for the 8080, commenting on the Open Letter to Hobbyists: Palo Alto Tiny BASIC Palo Alto Tiny BASIC was the fourth version of a Tiny BASIC interpreter that appeared in '' D ...

Copyleft All Wrongs Reserved
Copyleft is the legal technique of granting certain freedoms over copies of copyrighted works with the requirement that the same rights be preserved in derivative works. In this sense, ''freedoms'' refers to the use of the work for any purpose, and the ability to modify, copy, share, and redistribute the work, with or without a fee. Licenses which implement copyleft can be used to maintain copyright conditions for works ranging from computer software, to documents, art, scientific discoveries and even certain patents. Copyleft software licenses are considered ''protective'' or ''reciprocal'' in contrast with permissive free software licenses, and require that information necessary for reproducing and modifying the work must be made available to recipients of the software program, which are often distributed as binary executables. This information is most commonly in the form of source code files, which usually contain a copy of the license terms and acknowledge the authors of ...

Input/output
In computing, input/output (I/O, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices. Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. Any interaction with the system by a interactor is an input and the reaction the system responds is called the output. The designation of a device as either input or output depends on perspective.

New York City
New York, often called New York City or NYC, is the List of United States cities by population, most populous city in the United States. With a 2020 population of 8,804,190 distributed over , New York City is also the List of United States cities by population density, most densely populated major city in the United States, and is more than twice as populous as second-place Los Angeles. New York City lies at the southern tip of New York (state), New York State, and constitutes the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the world by urban area, urban landmass. With over 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York is one of the world's most populous Megacity, megacities, and over 58 million people live within of the city.

Fifth Avenue (Brooklyn)
This article provides a listing (with simple descriptions, where possible) of the streets in the New York City borough of Brooklyn, including Fort Hamilton, the last active-duty military post in New York City. State-named roadways Avenues Numbered Avenues Apart from the portion of 3rd through 7th Avenues beyond 86th Street, the numbered avenues run approximately 40 degrees west of south, but by local custom are called North–south. Boulevards Courts Lanes Loops Parkways Places Roads Streets Named streets Named streets in Greenpoint The east–west streets in Greenpoint are in mostly alphabetical order from north to south. Originally, these streets were simply given lettered names such as "A Street" and "B Street", but in the mid-19th century, the streets were given longer names. This system persists today with a few exceptions: Ash, Box, Clay, Dupont, Eagle, Freeman, Greene, Huron, India, Java, Kent, Greenpoint Avenue (formerly Lincoln Street), Milton, ...

Byte (magazine)
''Byte'' (stylized as ''BYTE'') was a microcomputer magazine, influential in the late 1970s and throughout the 1980s because of its wide-ranging editorial coverage. "''Byte'' magazine, the leading publication serving the homebrew market ..." ''Byte'' started in 1975, shortly after the first personal computers appeared as kits advertised in the back of electronics magazines. ''Byte'' was published monthly, with an initial yearly subscription price of $10. Whereas many magazines were dedicated to specific systems or the home or business users' perspective, ''Byte'' covered developments in the entire field of "small computers and software", and sometimes other computing fields such as supercomputers and high-reliability computing. Coverage was in-depth with much technical detail, rather than user-oriented. The company was purchased by McGraw-Hill in 1979, a watershed event that led to the rapid purchase of many of the early computer magazines by larger publishers. By this time t ...
