Compute!
''Compute!'' (), often stylized as ''COMPUTE!'', was an American home computer magazine that was published from 1979 to 1994. Its origins can be traced to 1978 in Len Lindsay's ''PET Gazette'', one of the first magazines for the Commodore PET computer. In its 1980s heyday ''Compute!'' covered all major platforms, and several single-platform spinoffs of the magazine were launched. The most successful of these was ''Compute!'s Gazette'', which catered to VIC-20 and Commodore 64 computer users. History ''Compute!''s original goal was to write about and publish programs for all of the computers that used some version of the MOS Technology 6502 CPU. It started out in 1979 with the Commodore PET, VIC-20, Atari 400/800, Apple II+, and some 6502-based computers one could build from kits, such as the Rockwell AIM 65, the KIM-1 by MOS Technology, and others from companies such as Ohio Scientific. Coverage of the kit computers and the Commodore PET were eventually dropped. The platforms t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BASIC
BASIC (Beginners' All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers. At the time, nearly all computers required writing custom software, which only scientists and mathematicians tended to learn. In addition to the program language, Kemeny and Kurtz developed the Dartmouth Time Sharing System (DTSS), which allowed multiple users to edit and run BASIC programs simultaneously on remote terminals. This general model became very popular on minicomputer systems like the PDP-11 and Data General Nova in the late 1960s and early 1970s. Hewlett-Packard produced an entire computer line for this method of operation, introducing the HP2000 series in the late 1960s and continuing sales into the 1980s. Many early video games trace their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kermit (protocol)
Kermit is a computer file transfer/management protocol and a set of communications software tools primarily used in the early years of personal computing in the 1980s. It provides a consistent approach to file transfer, terminal emulation, script programming, and character set conversion across many different computer hardware and operating system platforms. Technical The Kermit protocol supports text and binary file transfers on both full-duplex and half-duplex 8-bit and 7-bit serial connections in a system- and medium-independent fashion, and is implemented on hundreds of different computer and operating system platforms. On full-duplex connections, a sliding window protocol is used with selective retransmission which provides excellent performance and error recovery characteristics. On 7-bit connections, locking shifts provide efficient transfer of 8-bit data. When properly implemented, as in the Columbia University Kermit Software collection, its authors claim performance i ...

Columbia University
Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence. It is a member of the Ivy League. Columbia is ranked among the top universities in the world. Columbia was established by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University. Columbia scientists and scholars have ...

Typographic Alignment
In typesetting and page layout, alignment or range is the setting of text flow or image placement relative to a page, column (measure), table cell, or tab (and often to an image above it or under it). The type alignment setting is sometimes referred to as text alignment, text justification, or type justification. The edge of a page or column is known as a ''margin'', and a gap between columns is known as a ''gutter''. Basic variations There are four basic typographic alignments: * flush left—the text is aligned along the left margin or gutter, also known as ''left-aligned'', ''ragged right'' or ''ranged left''; * flush right—the text is aligned along the right margin or gutter, also known as ''right-aligned'', ''ragged left'' or ''ranged right''; * justified—text is aligned along the left margin, with letter-spacing and word-spacing adjusted so that the text falls flush with both margins, also known as ''fully justified'' or ''full justification''; * centered—text is al ...

Undo
Undo is an interaction technique which is implemented in many computer programs. It erases the last change done to the document, reverting it to an older state. In some more advanced programs, such as graphic processing, undo will negate the last command done to the file being edited. With the possibility of undo, users can explore and work without fear of making mistakes, because they can easily be undone. The expectations for undo are easy to understand: to have a predictable functionality, and to include all "undoable" commands. Usually undo is available until the user undoes all executed operations. But there are some actions which are not stored in the undo list, and thus they cannot be undone. For example, ''save file'' is not undoable, but is queued in the list to show that it was executed. Another action which is usually not stored, and thus not undoable, is ''scrolling'' or ''selection''. The opposite of undo is ''redo''. The redo command reverses the undo or advances t ...

The Transactor
''The Transactor'' was a computer magazine directed at users of Commodore home computers. In contrast to other Commodore-focused publications such as ''Commodore Magazine'' and ''COMPUTE!'s Gazette'', ''The Transactor'''s popularity was based on its coverage of deep technical issues and hardware hacking. ''INFO'' called ''The Transactor'' "the undeniable authority" on "Commodore programming and hardware information". Publication history The magazine was launched on 30 April 1978 as the official international bulletin of Commodore Canada to PET user groups. The early issues were low-tech mimeographed productions with no non-Commodore advertising and a roughly monthly release schedule. Despite its association with Commodore, the magazine earned a reputation for being honest and upfront about bugs and faults in Commodore's products. In September 1982 the magazine was relaunched as a fully independent, bimonthly, advertiser-supported publication. From this point the magazine became ...

File Deletion
File deletion is the removal of a computer file, file from a computer's file system. All operating systems include commands for deleting files (rm (Unix), rm on Unix, del (command), era in CP/M and DR-DOS, del (command), del/del (command), erase in MS-DOS/PC DOS, DR-DOS, Microsoft Windows etc.). File managers also provide a convenient way of deleting files. Files may be deleted one-by-one, or a whole blacklist directory tree may be deleted. Purpose Examples of reasons for deleting files are: *Freeing the disk space *Removing duplicate or unnecessary data to avoid confusion *Making Information sensitivity, sensitive information unavailable to others *Removing an operating system or blanking a hard drive Accidental removal A common problem with deleting files is the accidental removal of information that later proves to be important. A common method to prevent this is to Backup, back up files regularly. Erroneously deleted files may then be found in archives. Another techniqu ...

Spell Checker
In software, a spell checker (or spelling checker or spell check) is a software feature that checks for misspellings in a text. Spell-checking features are often embedded in software or services, such as a word processor, email client, electronic dictionary, or search engine. Design A basic spell checker carries out the following processes: * It scans the text and extracts the words contained in it. * It then compares each word with a known list of correctly spelled words (i.e. a dictionary). This might contain just a list of words, or it might also contain additional information, such as hyphenation points or lexical and grammatical attributes. * An additional step is a language-dependent algorithm for handling morphology. Even for a lightly inflected language like English, the spell checker will need to consider different forms of the same word, such as plurals, verbal forms, contractions, and possessives. For many other languages, such as those featuring agglutination and more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
