Seaside (software)
Seaside, an acronym that stands for “Squeak Enterprise Aubergines Server with Integrated Development Environment,” is computer software, a web framework to develop web applications in the programming language Smalltalk. It is distributed as free and open-source software under an MIT License. Seaside provides a component architecture in which web pages are built as trees of individual, stateful components, each encapsulating a small part of a page. Seaside uses continuations to model multiple independent flows between different components. Thus, it is a continuation-based web framework based on the ability to manipulate the execution stack of some implementations of Smalltalk. Key features Although subsequent improvement of state handling in web browser JavaScript engines have meant this aspect is less important today, Seaside's method of handling of browser state (via continuations) was an initial point of interest in the first years following its 2002 release.

Integrated Development Environment
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not. The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram for use in object-oriented software development. Overview Integrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program i ...

VisualWorks
VisualWorks is a cross-platform implementation of the Smalltalk language. It is implemented as a development system based on "images", which are dynamic collections of software objects, each contained in a system image. The lineage of VisualWorks goes back to the first Smalltalk-80 implementation by Xerox PARC. In the late 1980s, a group of Smalltalk-80 developers spun off ParcPlace Systems to further develop Smalltalk-80 as a commercial product. The commercial product was initially called ObjectWorks, and then VisualWorks. On August 31, 1999, the VisualWorks product was sold to Cincom. VisualWorks runs under many operating systems, including Windows, Mac OS X, Linux, and several versions of Unix. VisualWorks supports cross-platform development projects, because of its built-in multi-platform features. For example, a GUI application needs to be developed only once, and can then be switched to different widget styles. A VisualWorks application can be run on all supported platform ...

Squeak
Squeak is an object-oriented, class-based, and reflective programming language. It was derived from Smalltalk-80 by a group that included some of Smalltalk-80's original developers, initially at Apple Computer, then at Walt Disney Imagineering, where it was intended for use in internal Disney projects. The group would later go on to be supported by HP labs, SAP, and most recently, Y Combinator. Squeak runs on a virtual machine (VM), allowing for a high degree of portability. The Squeak system includes code for generating a new version of the VM on which it runs, along with a VM simulator written in Squeak. Developers Dan Ingalls, an important contributor to the Squeak project, wrote the paper upon which Squeak is built, and constructed the architecture for five generations of the Smalltalk language. Alan Kay is an important contributor to the Squeak project, and Squeak incorporates many elements of his proposed Dynabook concept. User interface frameworks Squeak includes four ...

Pharo
Pharo is an open source, cross-platform implementation of the classic Smalltalk-80 programming language and runtime. It's based on the OpenSmalltalk virtual machine called Cog (VM), which evaluates a dynamic, Reflective programming, reflective, and Object-oriented programming, object-oriented programming language with a syntax closely resembling Smalltalk#Syntax, Smalltalk-80. Pharo is shipped with a source code compiled into a ''system image'' that contains all software necessary to run Pharo system. Like the original Smalltalk-80, Pharo provides several live programming features such as immediate object manipulation, Reflective programming, live updates, and just-in-time compilation. The image includes an IDE-like software to modify its components. Pharo was forked from Squeak v3.9 in March of 2008. Overview Pharo is a pure object-oriented dynamically typed and reflective language. The stated goal of Pharo is to revisit Smalltalk design and enhance it. The name Phar ...

Dabble DB
Dabble DB was a web application written using the Seaside web framework which allows users to create database applications using a web browser. A Dabble DB application can import data and export data in a variety of formats. Unlike most traditional relational database systems, it uses a point-and-click interface rather than relying on programming. The system is forgiving of data type issues when importing or entering data. On June 10, 2010, Dabble DB announced that their parent company, Smallthought Systems, had been acquired by Twitter Twitter is an online social media and social networking service owned and operated by American company Twitter, Inc., on which users post and interact with 280-character-long messages known as "tweets". Registered users can post, like, and .... On March 17, 2011, Dabble DB announced that the Dabble DB service would be shut down on May 18, 2011. On March 31, 2011, Morningstar ran a story about Dabble DB users being thrown a lifeline. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comet (programming)
Comet is a web application model in which a long-held HTTPS request allows a web server to push data to a browser, without the browser explicitly requesting it. ''Comet'' is an umbrella term, encompassing multiple techniques for achieving this interaction. All these methods rely on features included by default in browsers, such as JavaScript, rather than on non-default plugins. The Comet approach differs from the original model of the web, in which a browser requests a complete web page at a time. The use of Comet techniques in web development predates the use of the word ''Comet'' as a neologism for the collective techniques. Comet is known by several other names, including ''Ajax Push'', ''Reverse Ajax'', ''Two-way-web'', ''HTTP Streaming'', and '' HTTP push, HTTP server push'' among others. The term ''Comet'' is not an acronym, but was coined by Alex Russell in his 2006 blog post ''Comet: Low Latency Data for the Browser''. In recent years, the standardisation and widespread s ...

JQuery
jQuery is a JavaScript library designed to simplify HTML DOM tree traversal and manipulation, as well as event handling, CSS animation, and Ajax. It is free, open-source software using the permissive MIT License. As of Aug 2022, jQuery is used by 77% of the 10 million most popular websites. Web analysis indicates that it is the most widely deployed JavaScript library by a large margin, having at least 3 to 4 times more usage than any other JavaScript library. jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library. This enables developers to create abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets. The modular approach to the jQuery library allows the creation of powerful dynamic web pages and Web applications. The set of ...

Ajax (programming)
Ajax (also AJAX ; short for " Asynchronous JavaScript and XML") is a set of web development techniques that uses various web technologies on the client-side to create asynchronous web applications. With Ajax, web applications can send and retrieve data from a server asynchronously (in the background) without interfering with the display and behaviour of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows web pages and, by extension, web applications, to change content dynamically without the need to reload the entire page. In practice, modern implementations commonly utilize JSON instead of XML. Ajax is not a technology, but rather a programming concept. HTML and CSS can be used in combination to mark up and style information. The webpage can be modified by JavaScript to dynamically display—and allow the user to interact with the new information. The built-in XMLHttpRequest object is used to execute Ajax on webpages, allowing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cascading Style Sheets
Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language such as HTML or XML (including XML dialects such as SVG, MathML or XHTML). CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript. CSS is designed to enable the separation of content and presentation, including layout, colors, and fonts. This separation can improve content accessibility; provide more flexibility and control in the specification of presentation characteristics; enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, which reduces complexity and repetition in the structural content; and enable the .css file to be cached to improve the page load speed between the pages that share the file and its formatting. Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering metho ...

Closure (computer Programming)
In programming languages, a closure, also lexical closure or function closure, is a technique for implementing lexically scoped name binding in a language with first-class functions. Operationally, a closure is a record storing a function together with an environment. The environment is a mapping associating each free variable of the function (variables that are used locally, but defined in an enclosing scope) with the value or reference to which the name was bound when the closure was created. Unlike a plain function, a closure allows the function to access those ''captured variables'' through the closure's copies of their values or references, even when the function is invoked outside their scope. History and etymology The concept of closures was developed in the 1960s for the mechanical evaluation of expressions in the λ-calculus and was first fully implemented in 1970 as a language feature in the PAL programming language to support lexically scoped first-class functions. ...
