Formally, a message authentication code (MAC) system is a triple of efficient [4] algorithms (G, S, V) satisfying: G (key-generator) gives the key k on input 1 n, where n is the security parameter. S (signing) outputs a tag t on the key k and the input string x. V (verifying) outputs accepted or rejected on inputs: the key k, the string x and ...
With the purchase of NeXT in late 1996, Apple developed a new operating system strategy based largely on the existing OPENSTEP for Mach platform. The new Rhapsody OS strategy was relatively simple; it retained most of OpenStep's existing object libraries under the name "Yellow Box", ported the existing GUI in OPENSTEP for Mach and made it look more Mac-like, ported several major APIs from the ...
Mac OS X uses Cocoa. Mac OS 9 and Mac OS X used to use Carbon for 32-bit applications. The Windows API used in Microsoft Windows. Microsoft had the graphics functions integrated in the kernel until 2006 [1] The Haiku operating system uses an extended and modernised version of the Be API that was used by its predecessor BeOS. Haiku is expected ...

Apple events form the basis of the Mac OS scripting system, the Open Scripting Architecture (the primary language of such being AppleScript). The starting point is a dynamically-typed, extensible descriptor format called an AEDesc , which is just an OSType code specifying the data type, together with a block of type-dependent data.
Keycode is different from scancode, the sequence of data generated when pressing or releasing a key on a computer keyboard, however, in legacy documents it may still refer to scancode. Keycode or may refer to: Keykode, an Eastman Kodak's a bar coding placed at regular intervals on negative films; Keycode, for a lock
These may be activated in different ways, but all function in essentially the same manner.) Selecting a script in the script menu launches it. Since Mac OS X 10.6.x, the system-wide script menu can be enabled from the preferences of Script Editor; in prior versions of Mac OS X, it could be enabled from the AppleScript Utility application. When ...
This key always generates the same keycode, but the symbols /, 7, and {are associated to three different keysyms. In the X Window System, every individual, physical key is associated a number in the range 8–255, called its keycode. A keycode only identifies a key, not a particular character or term (e.g., "Page Up") among the ones that may be ...
