Rhapsody (OS)
Rhapsody is an operating system that was developed by Apple Computer after its purchase of NeXT in the late 1990s. It is the fifth major release of the Mach-based operating system that was developed at NeXT in the late 1980s, previously called OPENSTEP and NEXTSTEP. Rhapsody was targeted to developers for a transition period between the Classic Mac OS and Mac OS X. Rhapsody represented a new and exploratory strategy for Apple, more than an operating system, and runs on x86-based PCs and on Power Macintosh. Rhapsody's OPENSTEP based Yellow Box API frameworks were ported to Windows NT for creating cross-platform applications. Eventually, the non-Apple platforms were discontinued, and later versions consist primarily of the OPENSTEP operating system ported to Power Macintosh, merging the Copland-originated GUI of Mac OS 8 with that of OPENSTEP. Several existing classic Mac OS frameworks were ported, including QuickTime and AppleSearch. Rhapsody can run Mac OS 8 and its applicati ...

QuickTime
QuickTime (or QuickTime Player) is an extensible multimedia architecture created by Apple, which supports playing, streaming, encoding, and transcoding a variety of digital media formats. The term ''QuickTime'' also refers to the QuickTime Player front-end media player application, which is built-into macOS, and was formerly available for Windows. QuickTime was created in 1991, when the concept of playing digital video directly on computers was "groundbreaking." QuickTime could embed a number of advanced media types, including panoramic images (called QuickTime VR) and Adobe Flash. Over the 1990s, QuickTime became a dominant standard for digital multimedia, as it was integrated into many websites, applications, and video games, and adopted by professional filmmakers. The QuickTime File Format became the basis for the MPEG-4 standard. During its heyday, QuickTime was notably used to create the innovative ''Myst'' and '' Xplora1'' video games, and to exclusively distribute mo ...

OPENSTEP
OpenStep is an object-oriented application programming interface (API) specification developed by NeXT. It provides a framework for building graphical user interfaces (GUIs) and developing software applications. OpenStep was designed to be platform-independent, allowing developers to write code that could run on multiple operating systems, including NeXTSTEP, Windows NT, and various Unix-based systems. It has influenced the development of other GUI frameworks, such as Cocoa for macOS, and GNUstep. OpenStep was principally developed by NeXT and Sun Microsystems, to allow advanced application development on Sun's operating systems, specifically Solaris. NeXT produced a version of OpenStep for its own Mach-based Unix OS, stylized in all capital letters as OPENSTEP. The software libraries that shipped with OPENSTEP are a superset of the original OpenStep specification, including many features from the original NeXTSTEP. History Workstations from Sun Microsystems were originally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Gershwin
George Gershwin (; born Jacob Gershwine; September 26, 1898 – July 11, 1937) was an American composer and pianist whose compositions spanned jazz, popular music, popular and classical music. Among his best-known works are the songs "Swanee (song), Swanee" (1919) and "Fascinating Rhythm" (1924), the orchestral compositions ''Rhapsody in Blue'' (1924) and ''An American in Paris'' (1928), the jazz standards "Embraceable You" (1928) and "I Got Rhythm" (1930) and the opera ''Porgy and Bess'' (1935), which included the hit "Summertime (George Gershwin song), Summertime". His ''Of Thee I Sing'' (1931) was the first musical theater, musical to win the Pulitzer Prize for Drama. Gershwin studied piano under Charles Hambitzer and composition with Rubin Goldmark, Henry Cowell, and Joseph Brody. He began his career as a song plugger but soon started composing Broadway theater works with his brother Ira Gershwin and with Buddy DeSylva. He moved to Paris, intending to study with Nadia ...

Aaron Copland
Aaron Copland (, ; November 14, 1900December 2, 1990) was an American composer, critic, writer, teacher, pianist, and conductor of his own and other American music. Copland was referred to by his peers and critics as the "Dean of American Composers". The open, slowly changing harmonies in much of his music are typical of what many consider the sound of American music, evoking the vast American landscape and pioneer spirit. He is best known for the works he wrote in the 1930s and 1940s in a deliberately accessible style often referred to as "populist" and which he called his "vernacular" style. Works in this vein include the ballets ''Appalachian Spring'', ''Billy the Kid (ballet), Billy the Kid'' and ''Rodeo (ballet), Rodeo'', his ''Fanfare for the Common Man'' and Symphony No. 3 (Copland), Third Symphony. In addition to his ballets and orchestral works, he produced music in many other genres, including chamber music, vocal works, opera, and film scores. After some initial studie ...

Rhapsody (music)
A rhapsody in music is a one-movement (music), movement work that is episodic yet integrated, free-flowing in structure, featuring a range of highly contrasted moods, colour, and tonality. An air of spontaneous inspiration and a sense of improvisation make it freer in form than a set of variation (music), variations. The word ''rhapsody'' is derived from the , ''rhapsōidos'', a reciter of epic poetry (a rhapsode, rhapsodist), and came to be used in Europe by the 16th century as a designation for literary forms, not only epic poems, but also for collections of miscellaneous writings and, later, any extravagant expression of sentiment or feeling. In the 18th century, literary rhapsodies first became linked with music, as in Christian Friedrich Daniel Schubart's ''Musicalische Rhapsodien'' (1786), a collection of songs with keyboard accompaniment, together with a few solo keyboard pieces. The first solo piano compositions with the title, however, were Václav Tomášek, Václav Jan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Codename
A code name, codename, call sign, or cryptonym is a code word or name used, sometimes clandestinely, to refer to another name, word, project, or person. Code names are often used for military purposes, or in espionage. They may also be used in industrial counter-espionage to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of cumulative errors over a walkie-talkie or radio link than actual names. Origins Achaemenid Empire The Achaemenid Empire under Darius I employed a network of spies called the King’s Eye or the King’s Ear. These agents operated under anonymity, and “King’s Eye” was not a specific person but rather a code name for the intelligence network that reported directly to the king. Punic Wars The Carthaginian general Hannibal Barca reportedly used coded re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paravirtualization
In computing, virtualization (abbreviated v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers. Virtualization began in the 1960s with IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. In hardware virtualization, the ''host machine'' is the machine that is used by the virtualization and the ''guest machine'' is the virtual machine. The words ''host'' and ''guest'' are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a ''hypervisor'' or ''virtual machine monitor''. Hardware virtualization is not the same as hardware emulation. Hardware-assisted virtualization facilitates building a virtual machine monitor and allows guest OSes to be run in isolation. Desktop v ...

AppleSearch
AppleSearch was a client/server search engine from Apple Computer, first released for the classic Mac OS in 1994, being one of the first desktop search engines. AppleSearch was a client/server application, although the vast majority of the logic was located in the server. The server portion periodically crawled a set of administrator-configured locations on hard drives, CD-ROMs and the network using AppleShare, indexing the documents it found after converting them to plain text using the Claris XTND document conversion system. A later version of the server, 1.5, could also be pointed at selected WAIS servers, using their indexes directly in addition to local ones. The same server also acted as a WAIS server, respond to WAIS requests sent to it over the internet. The server also offered a set of AppleEvents for use from Mac programs. The server's query parser incorporated a number of features to help improve the ease-of-use of the query language. For instance, AppleSearch did ...

Classic Mac OS
Mac OS (originally System Software; retronym: Classic Mac OS) is the series of operating systems developed for the Mac (computer), Macintosh family of personal computers by Apple Computer, Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems. Apple released the Macintosh 128K, original Macintosh on January 24, 1984. The System 1, first version of the system software, which had no official name, was partially based on the Lisa OS, which Apple previously released for the Apple Lisa, Lisa computer in 1983. As part of an agreement allowing Xerox to buy Share (finance), shares in Apple at a favorable price, it also used concepts from the PARC (company), Xerox ...
