Getters/Setters. Evil. Period. - Yegor Bugayenko. There is an old debate, started in 2003 by Allen Holub in this Why getter and setter methods are evil famous article, about whether getters/setters is an anti-pattern and should be avoided or if it is something we inevitably need in object-oriented programming.

Getters/Setters. Evil. Period. - Yegor Bugayenko

I'll try to add my two cents to this discussion. The gist of the following text is this: getters and setters is a terrible practice and those who use it can't be excused. Again, to avoid any misunderstanding, I'm not saying that get/set should be avoided when possible. No. I'm saying that you should never have them near your code. Arrogant enough to catch your attention? Existing Arguments There are a few arguments against "accessors" (another name for getters and setters), in an object-oriented world. Tell, Don't Ask Allen Holub says, "Don't ask for the information you need to do the work; ask the object that has the information to do the work for you". All these justifications are reasonable, but they are missing the main point. Xah at Blogger: list comprehension, python, semantics & syntax, and the hacker idiocies. Guido wants to remove {lambda, map, reduce} in python.

Design patterns are reusable solutions to commonly occurring problems in software design. They are both exciting and a fascinating topic to explore in any programming language. One reason for this is that they help us build upon the combined experience of many developers that came before us and ensure we structure our code in an optimized way, meeting the needs of problems we're attempting to solve.

Design patterns also provide us a common vocabulary to describe solutions. This can be significantly simpler than describing syntax and semantics when we're attempting to convey a way of structuring a solution in code form to others. In this book we will explore applying both classical and modern design patterns to the JavaScript programming language. Target Audience This book is targeted at professional developers wishing to improve their knowledge of design patterns and how they can be applied to the JavaScript programming language. Acknowledgments Credits Reading We already use patterns everyday. Test Drive Your New Application on Engine Yard. Computation tree logic. Syntax of CTL[edit] The language of well formed formulas for CTL is generated by the following grammar: where.

Color Scheme Designer 3. Circuit simplification examples : Boolean Algebra. Let's begin with a semiconductor gate circuit in need of simplification. The "A," "B," and "C" input signals are assumed to be provided from switches, sensors, or perhaps other gate circuits. Where these signals originate is of no concern in the task of gate reduction. - Wrapping Functions in JavaScript. I find myself wrapping JavaScript functions more these days to add aspect-oriented behavior. - Wrapping Functions in JavaScript

One JavaScript file can define a function and another file can add more behavior. Problem Suppose we have a relatively standard library function for attaching event handlers to elements that works with both the DOM2 and Internet Explorer event models. var LIB = {}; LIB.on = function(element, type, callback) { // ... }; Ometa/ometa-js-old/prolog-base.js. ACE - The High Performance Code Editor for the Web. Web Features: Create a Mashup using our Web Integrator. Produce APIs on your own Convertigo's tools, built on our years of experience, provide you the confidence to produce an API around an existing site--be it public or your own--that will be useful for a long time to come.

Web Features: Create a Mashup using our Web Integrator

This tool makes the site modernization possible less expensively and on a much faster timeline than a complete rewrite. You can also use Web Integrator selectively so that even if you choose to rewrite heavily used sections, you can still use CWI for everything else, which majorly optimizes your resources. Create widgets with Convertigo's Web Clipper. Component-based software engineering. A simple example of two components expressed in UML 2.0.

Component-based software engineering

The checkout component, responsible for facilitating the customer's order, requires the card processing component to charge the customer's credit/debit card (functionality that the latter provides). Component-based software engineering (CBSE) (also known as component-based development (CBD)) is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system. It is a reuse-based approach to defining, implementing and composing loosely coupled independent components into systems. This practice aims to bring about an equally wide-ranging degree of benefits in both the short-term and the long-term for the software itself and for organizations that sponsor such software.

Portlets produce fragments of markup (HTML, XHTML, WML) code that are aggregated into a portal. Web portal. A portal may use a search engine API to permit users to search intranet content as opposed to extranet content by restricting which domains may be searched.

Web portal

Apart from this common search engines feature, web portals may offer other services such as e-mail, news, stock quotes, information from databases and even entertainment content. Portals provide a way for enterprises and organizations to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different web entities at various URLs. The features available may be restricted by whether access is by an authorized and authenticated user (employee,member) or an anonymous site visitor. Examples of early public web portals were AOL, Excite, Netvibes, iGoogle, MSN, Naver, Indiatimes, Rediff, Sify and Yahoo!.

See for example, the "My Yahoo! " History[edit] Classification[edit] Mashup (web application hybrid) In the past years, more and more Web applications have published APIs that enable software developers to easily integrate data and functions the SOA way, instead of building them by themselves.

Mashup (web application hybrid)

Mashups can be considered to have an active role in the evolution of social software and Web 2.0. Mashup composition tools are usually simple enough to be used by end-users. They generally do not require programming skills and rather support visual wiring of GUI widgets, services and components together. Home — Scriptaculous Documentation. is a set of JavaScript libraries to enhance the user interface of web sites.
