Minification (programming) 119 Compressing HTTP proxy Ziproxy, a forwarding, non-caching, compressing HTTP proxy targeted for traffic optimization, supports functionalities of code compression by means of optimization of code, named HTMLopt, CSSopt and JSopt (HTML/CSS/JS) which are analogous with Minification. Ziproxy works by recompressing pictures, gzipping text and data optimization.

Objective-J 120 Objective-J Paradigm Multi-paradigm: reflective, object oriented, functional, imperative, scripting Appeared in 2008 Developer 280 North, Inc. Typing discipline dynamic, weak, duck Influenced by Objective-C, JavaScript License LGPL Website http://cappuccino.org/ Objective-J is a programming language developed as part of the Cappuccino web development framework. Its syntax is nearly identical to the Objective-C syntax and it shares with JavaScript the same relationship that Objective-C has with the C programming language: that of being a strict, but small, superset; adding traditional inheritance and Smalltalk/Objective-C style dynamic dispatch. Pure JavaScript, being a prototype-based language, already has a notion of object orientation and inheritance, but Objective-J adds the use of class-based programming to JavaScript. Programs written in Objective-J need to be preprocessed before being run by a web browser's JavaScript virtual machine. This step can occur in the web browser at runtime or by a compiler which translates Objective-J programs into pure JavaScript code. The Objective-J compiler is written in JavaScript; consequently, deploying Objective-J programs does not require a web browser plug-in. Application The first widely known use of Objective-J was in the Cappuccino-based web application 280 Slides. Even though Objective-J can be used (and has been designed) independently from the Cappuccino framework, Objective-J has primarily been invented to support web development in Cappuccino. Syntax Objective-J is a superset of JavaScript, which implies that any valid JavaScript code is also valid Objective-J code. The following example shows the definition in Objective-J of a class named Address; this class extends the root object CPObject, which plays a role similar to the Objective-C's NSObject. This example differs from traditional Objective-C in that the root object reflects the underlying Cappuccino framework as opposed to Cocoa, Objective-J does not use pointers and, as such, type definitions do not contain asterisk characters (in Objective-C, all objects must be dynamically allocated). In addition, instance variable definitions are never done in the @implementation file. @implementation Address : CPObject { } CPString name; CPString city; - (id)initWithName:(CPString)aName city:(CPString)aCity { self = [super init];
