Ne (text Editor)
ne (for "nice editor") is a console text editor for POSIX computer operating systems such as Linux or Mac OS X. It uses the terminfo library, but it can also be compiled using a bundled copy of the GNU termcap implementation. There is also a Cygwin version. It was developed by Sebastiano Vigna of the University of Milan. ne is intended to provide an alternative to vi that will be more familiar to beginnerand modern users and still be portable across all POSIX-compliant operating systems, and remain usable on slow remote connections. It uses GUI-derived keyboard shortcuts such as to quit and to open a file instead of the multi-mode command structure of vi. It supports many features common in advanced text editors, such as syntax highlighting, regular expressions, configurable menus and keybindings and autocomplete. ne can pipe a marked block of text through any command line filter using the Through command bound to by defaulne has some support for UTF-8 encodian ...

Peter Norton Computing
Peter Norton Computing, Inc., was a software company founded by Peter Norton. The first and best known software package it produced was Norton Utilities. Another successful software package was Norton Commander, especially the DOS version. The company in this form lasted from its founding in 1982 until 1990, when it was acquired by Symantec (now Gen Digital). The Symantec merger helped Norton Computing regain the market share it was losing to competitors, especially Central Point Software. Norton Computing's revenues tripled between June 1990 and September 1991, and by November it appeared to have regained the market lead over Central Point. History Peter Norton founded the company in 1982 with $30,000 and an IBM computer. The company was a pioneer in DOS-based utilities software. Its 1982 introduction of the Norton Utilities included Norton's UNERASE tool to retrieve erased data from DOS disks. In 1984, Norton Computing reached $1 million in revenue, and version 3.0 of the Nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syntax Highlighting
Syntax highlighting is a feature of text editors that is used for programming language, programming, scripting language, scripting, or markup language, markup languages, such as HTML. The feature displays text, especially source code, in different Text color, colours and fonts according to the category of terms. This feature facilitates writing in a structured language such as a programming language or a markup language as both structures and syntax errors are visually distinct. This feature is also employed in many programming related contexts (such as programming manuals), either in the form of colourful books or online websites to make understanding code snippets easier for readers. Highlighting does not affect the meaning of the text itself; it is intended only for human readers. Syntax highlighting is a form of secondary notation, since the highlights are not part of the text meaning, but serve to reinforce it. Some editors also integrate syntax highlighting with other featu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNIX
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Curses (programming Library)
curses is a terminal control library for Unix-like systems, enabling the construction of text user interface (TUI) applications. The name is a pun on the term " cursor optimization". It is a library of functions that manage an application's display on character-cell terminals (e.g., VT100). ncurses is the approved replacement for 4.4BSD classic curses. Overview Using curses, programmers are able to write text-based applications without writing directly for any specific terminal type. The curses library on the executing system sends the correct control characters based on the terminal type. It provides an abstraction of one or more windows that maps onto the terminal screen. Each window is represented by a character matrix. The programmer sets up the desired appearance of each window, then tells the curses package to update the screen. The library determines a minimal set of changes that are needed to update the display and then executes these using the terminal's specifi ...

Amiga 3000T
The Amiga 3000T is a computer manufactured by Commodore. It is closely related to the Amiga 3000, although it came in a tower case which offers greater expandability. The case for the prototype, the 3500, was derived from Commodore's PC compatible line. Like the desktop variant it is based upon, the A3000T has a CPU FAST slot which allows for processor upgrades. Later models were offered with a 68040 CPU in this slot, and third-party upgrades can be used to add a PowerPC processor. The A3000T has a variety of drive bays two 3.5-inch drives and one 5.25-inch half-height drive, mounted horizontally; and two 5.25-inch half-height drives mounted vertically. Inside, behind these bays, there is space for two more, internal, 5.25-inch half-height drives. The available drive bays make it possible to internally install up to seven drives in the A3000T. The A3000T's specifications closely resemble the horizontal-cased Amiga 3000, but the motherboard has been heavily redesigned. As a re ...

8-bit Clean
''8-bit clean'' is an attribute of computer systems, communication channels, and other devices and software, that process 8-bit character encodings without treating any byte as an in-band control code. History Until the early 1990s, many programs and data transmission channels were character-oriented and treated some characters, e.g., ETX, as control characters. Others assumed a stream of seven-bit characters, with values between 0 and 127; for example, the ASCII standard used only seven bits per character, avoiding an 8-bit representation in order to save on data transmission costs. On computers and data links using 8-bit bytes, this left the top bit of each byte free for use as a parity, flag bit, or metadata control bit. 7-bit systems and data links are unable to directly handle more complex character codes which are commonplace in non- English-speaking countries with larger alphabets. Binary files of octets cannot be transmitted through 7-bit data channels directly. To ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UTF-8
UTF-8 is a character encoding standard used for electronic communication. Defined by the Unicode Standard, the name is derived from ''Unicode Transformation Format 8-bit''. Almost every webpage is transmitted as UTF-8. UTF-8 supports all 1,112,064 valid Unicode code points using a variable-width encoding of one to four one- byte (8-bit) code units. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes. It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that a UTF-8-encoded file using only those characters is identical to an ASCII file. Most software designed for any extended ASCII can read and write UTF-8, and this results in fewer internationalization issues than any alternative text encoding. UTF-8 is dominant for all countries/languages on the internet, with 99% global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meta Key
The Meta key is a modifier key on certain Computer keyboard, keyboards. It first appeared on the Stanford Artificial Intelligence Lab (SAIL) keyboard in 1970. History The Meta key first appeared on the Stanford Artificial Intelligence Lab (SAIL) keyboard in 1970 and successors such as the Knight keyboard, space-cadet keyboard, Massachusetts Institute of Technology, MIT Lisp machine, Symbolics keyboards, and on Sun Microsystems keyboards (where it is marked with a black diamond "◆"). Use Generally, the Meta key worked similar to Macintosh's Command key, in that when held down it modified letters and symbols into immediate commands (shortcuts). On these keyboards the Control key was placed closest to the space bar, then the Meta key outside Control. The space-cadet keyboard added the Super key (keyboard button), Super key outside Meta, and the Hyper key outside that. All these keys produced shortcuts (24-1 of them for every letter), but the Control ones were easiest to type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filter (Unix)
A filter is a computer program or subroutine to process a stream, producing another stream. While a single filter can be used individually, they are frequently strung together to form a pipeline. Some operating systems such as Unix are rich with filter programs. Windows 7 and later are also rich with filters, as they include Windows PowerShell. In comparison, however, few filters are built into cmd.exe (the original command-line interface of Windows), most of which have significant enhancements relative to the similar filter commands that were available in MS-DOS. OS X includes filters from its underlying Unix base but also has Automator, which allows filters (known as "Actions") to be strung together to form a pipeline. Unix In Unix and Unix-like operating systems, a filter is a program that gets most of its data from its standard input (the main input stream) and writes its main results to its standard output (the main output stream). Auxiliary input may come from command line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pipe (computing)
The vertical bar, , is a glyph with various uses in mathematics, computing, and typography. It has many names, often related to particular meanings: Sheffer stroke (in logic), pipe, bar, or (literally, the word "or"), vbar, and others. Usage Mathematics The vertical bar is used as a mathematical symbol in numerous ways. If used as a pair of brackets, it suggests the notion of the word "size". These are: * absolute value: , x, , read "the ''absolute value'' of ''x''" * cardinality: , S, , read "the ''cardinality'' of the set ''S''" or "the ''length'' of a string ''S''" * determinant: , A, , read "the ''determinant'' of the matrix ''A''". When the matrix entries are written out, the determinant is denoted by surrounding the matrix entries by vertical bars instead of the usual brackets or parentheses of the matrix, as in \begin a & b \\ c & d\end. * order: , G, , read "the ''order'' of the group ''G''", or , g, , "the ''order'' of the element g \in G" Likewise, the vertical bar is ...

Autocomplete
Autocomplete, or word completion, is a feature in which an application software, application predicts the rest of a word a user is typing. In Android (operating system), Android and iOS smartphones, this is called predictive text. In graphical user interfaces, users can typically press the tab key to accept a suggestion or the down arrow key to accept one of several. Autocomplete speeds up human-computer interactions when it correctly predicts the word a user intends to enter after only a few characters have been typed into a text input field. It works best in domains with a limited number of possible words (such as in command line interpreters), when some words are much more common (such as when addressing an e-mail), or writing structured and predictable text (as in source code editors). Many autocomplete algorithms learn new words after the user has written them a few times, and can suggest alternatives based on the learned habits of the individual user. Definition Origina ...
