Bonobo (GNOME)
Bonobo is an obsolete component framework for the GNOME free desktop environment. Bonobo is designed to create reusable software components and compound documents. Through its development history it resembles Microsoft's OLE technology and is GNOME's equivalent of KDE's KParts. Bonobo was developed as a solution to the problems and requirements of the free software community in the development of complex applications. Bonobo is based on the Common Object Request Broker Architecture (CORBA) or its GNOME implementation ORBit. Through Bonobo the functions of one application can be integrated into another: for example, Gnumeric spreadsheet tables can be directly embedded into AbiWord text document by including Gnumeric as Bonobo component. Available components are: *Gnumeric spreadsheet *ggv PostScript viewer * Xpdf PDF viewer *gill SVG viewer History Inspired by Microsoft's OLE, Bonobo was originally developed by Ximian for compound documents. Bonobo was included for the first t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GNOME
A gnome () is a mythological creature and diminutive spirit in Renaissance magic and alchemy, introduced by Paracelsus in the 16th century and widely adopted by authors, including those of modern fantasy literature. They are typically depicted as small humanoids who live underground. Gnome characteristics are reinterpreted to suit various storytellers and artists. Paracelsus's gnome is recognized to have derived from the German miners' legend about or , the "metallurgical or mineralogical demon", according to Georg Agricola (1530), also called (literal Latinization of ''Bergmännlein'', "mountain manikin") by Agriocola in a later work (1549), and described by other names such as (sing. ; Latinization of German ). Agricola recorded that, according to the legends of that profession, these mining spirits acted as miming and laughing pranksters who sometimes threw pebbles at miners, but could also reward them by depositing a rich vein of silver ore. Paracelsus also called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PostScript
PostScript (PS) is a page description language and dynamically typed, stack-based programming language. It is most commonly used in the electronic publishing and desktop publishing realm, but as a Turing complete programming language, it can be used for many other purposes as well. PostScript was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. The most recent version, PostScript 3, was released in 1997. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time, Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975–76 Bob Sproull and William Newman developed the Press format, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inter-process Communication
In computer science, interprocess communication (IPC) is the sharing of data between running Process (computing), processes in a computer system. Mechanisms for IPC may be provided by an operating system. Applications which use IPC are often categorized as client–server model, clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing. IPC is very important to the design process for microkernels and nanokernels, which reduce the number of functionalities provided by the kernel. Those functionalities are then obtained by communicating with servers via IPC, leading to a large increase in communication when compared to a regular monolithic kernel. IPC interfaces generally encompass variable analytic framework structures. These processes ensure compatibility between the multi-vector protocols upon which IPC models rely. An IPC mechanism is either Synchroni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GTK+
GTK (formerly GIMP ToolKit and GTK+) is a free software cross-platform widget toolkit for creating graphical user interfaces (GUIs). It is licensed under the terms of the GNU Lesser General Public License, allowing both free and proprietary software to use it. It is one of the most popular toolkits for the Wayland and X11 windowing systems. The GTK team releases new versions on a regular basis. GTK 4 and GTK 3 are maintained, while GTK 2 is end-of-life. GTK1 is independently maintained by the CinePaint project. Software architecture The GTK library contains a set of graphical control elements ( widgets); version 3.22.16 contains 186 active and 36 deprecated widgets. GTK is an object-oriented widget toolkit written in the programming language C; it uses GObject (that is, the GLib object system) for object orientation. While GTK is mainly used with windowing systems based on X11 and Wayland, it works on other platforms, including Microsoft Windows ( ...

GLib
GLib is a bundle of three (formerly five) low-level system libraries written in C and developed mainly by GNOME. GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since. The name "GLib" originates from the project's start as a GTK C utility library. Features GLib provides advanced data structures, such as memory chunks, doubly and singly linked lists, hash tables, dynamic strings and string utilities, such as a lexical scanner, string chunks (groups of strings), dynamic arrays, balanced binary trees, N-ary trees, quarks (a two-way association of a string and a unique integer identifier), keyed data lists, relations, and tuples. Caches provide memory management. GLib implements functions that provide threads, thread programming and related facilities such as primitive variable access, mutexes, asynchronous queues, secure memory pools, message passing and logging, hook functions (callback regist ...

D-Bus
D-Bus (short for "Desktop Bus") is a message-oriented middleware mechanism that allows communication between multiple Process (computing), processes running concurrently on the same machine. D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE. The freedesktop.org project also developed a free and open-source software library called libdbus, as a reference implementation of the specification. This library is not D-Bus itself, as other implementations of the D-Bus specification also exist, such as GDBus (GNOME), QtDBus (Qt (software), Qt/KDE), dbus-java and sd-bus (part of systemd). Overview D-Bus is an inter-process communication (IPC) mechanism initially designed to replace the software component communications systems CORBA and Desktop communication protocol, DCOP, used by the GNOME and KDE Linux desktop environments respectively. The comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ximian
Ximian, Inc. (previously called Helix Code and originally named International Gnome Support) was an American company that developed, sold and supported application software for Linux and Unix based on the GNOME platform. It was founded by Miguel de Icaza and Nat Friedman in 1999 and was bought by Novell in 2003. Novell continued to develop Ximian's original products, while adding support for its own GroupWise and ZENworks software. History Miguel de Icaza had a job interview at Microsoft in 1997 shortly before he started the GNOME project. At Microsoft he met Nat Friedman, who worked there as an intern. Afterwards they became good friends. In April 1999 Friedman came up with the idea to create a company to work on GNOME. The company was founded on 19 October 1999 as International GNOME Support, but its name was changed to Helix Code later. Because that name could not be trademarked the name was changed to Ximian on 10 January 2001. Nat Friedman was the CEO of Ximian from its ...

Xpdf
Xpdf is a free and open-source PDF viewer and toolkit based on the Qt framework. Versions prior to 4.00 were written for the X Window System and Motif. Functions Xpdf runs on nearly any Unix-like operating system. Binaries are also available for Windows. Xpdf can decode LZW and read encrypted PDFs. The official version obeys the DRM restrictions of PDF files, which can prevent copying, printing, or converting some PDF files. There are patches that make Xpdf ignore these DRM restrictions; the Debian distribution, for example, has these patches in place by default. Xpdf includes several programs that don't need an X Window System, including some that extract images from PDF files or convert PDF to PostScript or text. These programs run on DOS, Windows, Linux and Unix. Xpdf is also used as a back-end for other PDF readers frontends such as KPDF and GPDF, and its engine, without the X11 display components, is used for PDF viewers including BePDF on BeOS, '!PDF' on RISC OS ...

Desktop Environment
In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphical shell. The desktop environment was seen mostly on personal computers until the rise of mobile computing. Desktop GUIs help the user to easily access and edit files, while they usually do not provide access to all of the features found in the underlying operating system. Instead, the traditional command-line interface (CLI) is still used when full control over the operating system is required. A desktop environment typically consists of icons, windows, toolbars, directory (file systems), folders, computer wallpaper, wallpapers and Widget engine, desktop widgets (see Elements of graphical user interfaces and WIMP_(computing), WIMP). A GUI might also provide drag and drop functionality and other features that make the desktop metaphor mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spreadsheet
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term ''spreadsheet'' may also refer to one such electronic document. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial ...

Gnumeric
Gnumeric is a spreadsheet program that is part of the GNOME Free Software Desktop Project. Gnumeric version 1.0 was released on 31 December 2001. Gnumeric is distributed as free software under the GNU General Public License; it is intended to replace proprietary spreadsheet programs like Microsoft Excel. Gnumeric was created and developed by Miguel de Icaza, but he has since moved on to other projects. The maintainer was Jody Goldberg. Features Gnumeric has the ability to import and export data in several file formats, including CSV, Microsoft Excel (write support for the more recent .xlsx format is incomplete), Microsoft Works spreadsheets (.wks), HTML, LaTeX, Lotus 1-2-3, OpenDocument and Quattro Pro; its native format is the ''Gnumeric file format'' (.gnm or .gnumeric), an XML file compressed with gzip. It includes all of the spreadsheet functions of the North American edition of Microsoft Excel and many functions unique to Gnumeric. Pivot tables and Visual Basic for A ...
