Gconf
GConf was a system used by the GNOME desktop environment for storing configuration settings for the desktop and applications. It is similar to the Windows Registry. It was deprecated as part of the GNOME 3 transition. Migration to its replacement, GSettings and dconf, is ongoing. Changes to this system are controlled by GConfd, a daemon. GConfd watches out for changes to the database, and when they are changed, it applies the new settings to applications using it. This technology is known as "auto-apply", compared to "explicit-apply", which requires users to press an OK or Apply button to make changes come into effect. The term "instant-apply" is sometimes used, compared to plain "apply". The GConf database by default uses a system of directories and XML files, stored in a directory called ~/.gconf. GConf can also use other backends, such as a database server, but XML file storage is the most common configuration. The application gconf-editor is provided to allow users ...

Gconf-editor
Gconf-editor is a discontinued utility for the GNOME desktop environment used to maintain the old and now discontinued GNOME registry gconf. Gconf-editor gives users the ability to access settings stored in the XML-based GConf configuration database or registry. It is used primarily by developers to debug applications, or by power users to edit hidden and complex settings. It abstracts the values from the GConf database and presents them in an interface similar to Microsoft Windows Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sec ...' registry editor. Other gconf tools have also appeared, such as Gconfpref by MandrakeSoft. There are also patches for popular applications, which add the ability to change the hidden options from within the application itself, avoiding the need for ...

GNU Privacy Guard
GNU Privacy Guard (GnuPG or GPG) is a free-software replacement for Symantec's cryptographic software suite PGP. The software is compliant with the now obsoleted , the IETF standards-track specification of OpenPGP. Modern versions of PGP are interoperable with GnuPG and other OpenPGP v4-compliant systems. November 2023 saw two drafts aiming to update the 2007 OpenPGP v4 specification (RFC4880), ultimately resulting in thRFC 9580standard in July 2024. The proposal from the GnuPG developers, which is called LibrePGP, was not taken up by the OpenPGP Working Group and future versions of GnuPG will not support the current version of OpenPGP. GnuPG is part of the GNU Project and received major funding from the German government in 1999. Overview GnuPG is a hybrid-encryption software program because it uses a combination of conventional symmetric-key cryptography for speed, and public-key cryptography for ease of secure key exchange, typically by using the recipient's publi ...

Database Schema
The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term "wikt:schema, schema" refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases). The formal definition of a database schema is a set of formulas (sentences) called integrity constraints imposed on a database. These integrity constraints ensure compatibility between parts of the schema. All constraints are expressible in the same language. A database can be considered a structure in realization of the database language. The states of a created conceptual schema are transformed into an explicit mapping, the database schema. This describes how real-world entities are Data modeling, modeled in the database. "A database schema specifies, based on the database administrator's knowledge of possible applications, the facts that can ent ...

Python (programming Language)
Python is a high-level programming language, high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is type system#DYNAMIC, dynamically type-checked and garbage collection (computer science), garbage-collected. It supports multiple programming paradigms, including structured programming, structured (particularly procedural programming, procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC (programming language), ABC programming language, and he first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000. Python 3.0, released in 2008, was a major revision not completely backward-compatible with earlier versions. Python 2.7.18, released in 2020, was the last release of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perl
Perl is a high-level, general-purpose, interpreted, dynamic programming language. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Perl originally was not capitalized and the name was changed to being capitalized by the time Perl 4 was released. The latest release is Perl 5, first released in 1994. From 2000 to October 2019 a sixth version of Perl was in development; the sixth version's name was changed to Raku. Both languages continue to be developed independently by different development teams which liberally borrow ideas from each other. Perl borrows features from other programming languages including C, sh, AWK, and sed. It provides text processing facilities without the arbitrary data-length limits of ...

Software Localization
In computing, internationalization and localization ( American) or internationalisation and localisation (British), often abbreviated i18n and l10n respectively, are means of adapting to different languages, regional peculiarities and technical requirements of a target locale. Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes. Localization is the process of adapting internationalized software for a specific region or language by translating text and adding locale-specific components. Localization (which is potentially performed multiple times, for different locales) uses the infrastructure or flexibility provided by internationalization (which is ideally performed only once before localization, or as an integral part of ongoing development). Naming The terms are frequently abbreviated to the numeronyms ''i18n'' (where ''18'' stands for the number of letters between the ...

Callback (computer Science)
In computer programming, a callback is a Function (computer programming), function that is stored as data (a Reference (computer science), reference) and designed to be called by another function often ''back'' to the original Abstraction (computer science), abstraction layer. A function that accepts a callback Parameter (computer programming), parameter may be designed to call back before Return statement, returning to its caller which is known as ''Synchronization (computer science), synchronous'' or ''blocking''. The function that accepts a callback may be designed to store the callback so that it can be called back after returning which is known as ''asynchronous'', ''Non-blocking algorithm, non-blocking'' or ''deferred''. Programming languages support callbacks in different ways such as function pointers, Lambda (programming), lambda expressions and block (programming), blocks. A callback can be likened to leaving instructions with a tailor for what to do when a suit is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GObject
The GLib Object System, or GObject, is a free software, free software library providing a portable object system and transparent cross-language interoperability. GObject is designed for use both directly in C (programming language), C programs to provide object-oriented C-based APIs and through language binding, bindings to other languages to provide transparent cross-language interoperability, e.g. PyGObject. History Depending only on GLib and libc, GObject is a cornerstone of GNOME and is used throughout GTK, Pango, Accessibility Toolkit, ATK, and most higher-level GNOME libraries like GStreamer and applications. Prior to GTK+ 2.0, code similar to GObject was part of the GTK codebase. (The name “GObject” was not yet in use — the common baseclass was called GtkObject.) At the release of GTK+ 2.0, the object system was extracted into a separate library due to its general utility. In the process, most non-GUI-specific parts of the GtkObject class were moved up into GOb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Path (computing)
A path (or filepath, file path, pathname, or similar) is a text string that uniquely specifies an item in a hierarchical file system. Generally, a path is composed of directory names, special directory specifiers and optionally a filename, separated by delimiting text. The delimiter varies by operating system and in theory can be anything, but popular, modern systems use slash , backslash , or colon . A path can be either relative or absolute. A relative path includes information that is relative to a particular directory whereas an absolute path indicates a location relative to the system root directory, and therefore, does not depends on context like a relative path does. Often, a relative path is relative to the working directory. For example, in command , is a relative path to the file with that name in the working directory. Paths are used extensively in computer science to represent the directory/file relationships common in modern operating systems and are essential ...
