Defaults (software)
defaults is a command line utility that manipulates plist files. Introduced in 1998 OPENSTEP, ''defaults'' is found in the system's descendants macOS and GNUstep. The name "defaults" derives from OpenStep's name for user preferences, ''Defaults'', or ''NSUserDefaults'' in Foundation Kit. Each application had its own defaults plist ("domain"), under for the user configuration and for the system configuration. The lookup system also supports a , where defaults written there will be seen by all applications. In macOS, the part of the path is replaced by the more intuitive . ''defaults'' accesses the plists based on the domain given. ''defaults'' is also able to read and write any plist specified with a path, although Apple plans to phase out this utility in a future version. Usage Common uses of defaults: $ defaults read DOMAIN # gets all $ defaults read DOMAIN PROPERTY_NAME # gets $ defaults write DOMAIN PROPERTY_NAME VALUE # sets $ defaults delete DOMAIN PROPERTY_NAM ...

Default (computer Science)
A default, in computer science, refers to the preexisting value of a user-configurable setting that is assigned to a software application, computer program or device. Such settings are also called presets or factory presets, especially for electronic devices. Default values are standards values that are universal to all instances of the device or model and intended to make the device as accessible as possible "out of the box" without necessitating a lengthy configuration process prior to use. The user only has to modify the default settings according to their personal preferences. In many devices, the user has the option to restore these default settings for one or all options. Such an assignment makes the choice of that setting or value more likely, this is called the default effect. Examples Application software preferences One use of default parameters is for initial settings for application software. For example, the first time a user runs an application it may suggest that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Command-line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. This provides a means of setting parameters for the environment, invoking executables and providing information to them as to what actions they are to perform. In some cases the invocation is conditional based on conditions established by the user or previous executables. Such access was first provided by computer terminals starting in the mid-1960s. This provided an interactive environment not available with punched cards or other input methods. Today, many users rely upon graphical user interfaces and menu-driven interactions. However, some programming and maintenance tasks may not have a graphical user interface and use a command line. Alternatives to the command-line interface include text-based user interface menus (for example, IBM AIX SMIT), keyboard shortcuts, and various desktop metaphors centered on the pointer ...

Property List
In the macOS, iOS, NeXTSTEP, and GNUstep programming frameworks, property list files are files that store serialized objects. Property list files use the filename extension .plist, and thus are often referred to as p-list files. Property list files are often used to store a user's settings. They are also used to store information about bundles and applications, a task served by the resource fork in the old Mac OS. Property lists are also used for localization strings for development. These files use the .strings or .stringsdict extensions. The former is a "reduced" old-style plist containing only one dictionary without the braces (see ), while the latter is a fully-fledged plist. Xcode also uses a .pbxproj extension for old-style plists used as project files. Representations Since the data represented by property lists is somewhat abstract, the underlying file format can be implemented many ways. Namely, NeXTSTEP used one format to represent a property list, and the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

OPENSTEP
OpenStep is a defunct object-oriented application programming interface (API) specification for a legacy object-oriented operating system, with the basic goal of offering a NeXTSTEP-like environment on non-NeXTSTEP operating systems. OpenStep was principally developed by NeXT with 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, stylized as OPENSTEP, as well as a version for Windows NT. The software libraries that shipped with OPENSTEP are a superset of the original OpenStep specification, including many features from the original NeXTSTEP. History In the early era of the Sun Microsystems history, Sun machines had been programmed at a relatively low-level making calls directly to the underlying Unix operating system and producing a graphical user interface (GUI) using the X11 system. This led to complex programming even for simple projects. An attempt to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MacOS
macOS (; previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac (computer), Mac computers. Within the market of desktop and laptop computers it is the Usage share of operating systems#Desktop and laptop computers, second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. macOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT Computer, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. All releases from Mac OS X Leopard, Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X Lion, OS X 10. ...

GNUstep
GNUstep is a free software implementation of the Cocoa (formerly OpenStep) Objective-C frameworks, widget toolkit, and application development tools for Unix-like operating systems and Microsoft Windows. It is part of the GNU Project. GNUstep features a cross-platform, object-oriented IDE. Apart from the default Objective-C interface, GNUstep also has bindings for Java, Ruby, GNU Guile and Scheme. The GNUstep developers track some additions to Apple's Cocoa to remain compatible. The roots of the GNUstep application interface are the same as the roots of Cocoa: NeXTSTEP and OpenStep. GNUstep thus predates Cocoa, which emerged when Apple acquired NeXT's technology and incorporated it into the development of the original Mac OS X, while GNUstep was initially an effort by GNU developers to replicate the technically ambitious NeXTSTEP's programmer-friendly features. History GNUstep began when Paul Kunz and others at Stanford Linear Accelerator Center wanted to port Hip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Configuration
In communications or computer systems, a configuration of a system refers to the arrangement of each of its functional units, according to their nature, number and chief characteristics. Often, configuration pertains to the choice of hardware, software, firmware, and documentation. Along with its architecture, the configuration of a computer system affects both its function and performance See also * Auto-configuration * Configuration management - In multiple disciplines, a practice for managing change ** Software configuration management * Configuration file - In software, a data resource used for program initialization *Configure script (computing) A configure script is an executable script designed to aid in developing a program to be run on a wide number of different computers. It matches the libraries on the user's computer, with those required by the program before compiling it from ... * Configurator * Settings (Windows) References * Federal Standard 1037C Exter ...

Foundation Kit
The Foundation Kit, or just Foundation for short, is an Objective-C framework in the OpenStep specification. It provides basic classes such as wrapper classes and data structure classes. This framework uses the prefix NS (for NeXTSTEP). It is also part of Cocoa and of the Swift standard library. Classes NSObject This class is the most common base class for Objective-C hierarchies and provides standard methods for working with objects by managing the memory associated with them and querying them. NSString and NSMutableString A class used for string manipulation, representing a Unicode string (most typically using UTF-16 as its internal format). NSString is immutable, and thus can only be initialized but not modified. NSMutableString is a modifiable version. NSValue and NSNumber NSValue is a wrapper class for C data types, and NSNumber is a wrapper class for C number data types such as int, double, and float. The data structures in Foundation Kit can only hold objects, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Home Directory
A home directory is a file system directory on a multi-user operating system containing files for a given user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD ( FHS) systems use /home/ and Windows systems between 2000 and Server 2003 keep home directories in a folder named Documents and Settings. Description A user's home directory is intended to contain that user's files; including text documents, music, pictures, videos, etc. It may also include their configuration files of preferred settings for any software they have used there and might have tailored to their liking: web browser bookmarks, favorite desktop wallpaper and themes, stored passwords to any external services accessed via a given software, etc. The user can install executable software in this directory, but it will only be available to users with permission to execute files in this directory.

Root Directory
In a computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most directory in a hierarchy. It can be likened to the trunk of a tree, as the starting point where all branches originate from. The root file system is the file system contained on the same disk partition on which the root directory is located; it is the filesystem on top of which all other file systems are mounted as the system boots up. Unix-like systems Unix abstracts the nature of this tree hierarchy entirely and in Unix and Unix-like systems the root directory is denoted by the / (slash) sign. Though the root directory is conventionally referred to as /, the directory entry itself has no name its path is the "empty" part before the initial directory separator character (/). All file system entries, including mounted file systems are "branches" of this root. chroot In UNIX-like operating systems, each process has its own idea of what the ...

Reverse Domain Name Notation
Reverse domain name notation (or reverse-DNS) is a naming convention for components, packages, types or file names used by a programming language, system or framework. Reverse-DNS strings are based on registered domain names, with the order of the components reversed for grouping purposes. For example, if a company making the product "MyProduct" has the domain name example.com, they could use the reverse-DNS string com.example.MyProduct as an identifier for that product. Reverse-DNS names are a simple way of eliminating namespace collisions, since any domain name is globally unique to its registered owner. History The first appearance of reversed DNS strings predated the Internet domain name standards. The UK Joint Academic Networking Team (JANET) used this order in its Name Registration Scheme, before the Internet domain name standard was established. For example, the name uk.ac.bris.pys.as was interpreted as a host named as within the UK (top level domain .uk), while the Intern ...

Safari (web Browser)
Safari is a web browser developed by Apple. It is built into macOS, iOS, and iPadOS, and uses Apple's open-source browser engine, WebKit, which was derived from KHTML. Safari was introduced in Mac OS X Panther in January 2003. It was included with the iPhone since the latter's first generation, which came out in 2007. At that time, Safari was the fastest browser on the Mac. Between 2007 and 2012, Apple maintained a Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support Apple Pay, and authentication with FIDO2 security keys. Its interface was redesigned in Safari 15. In May 2022, Safari became the third most popular desktop browser after being overtaken by Microsoft Edge. Safari was then used by 9.61 percent of desktop computers worldwide. ...
