Why Node.js Is the Ideal Language for High-Performance Web Applications

NodeJSEvery ten or so years, a programming language emerges that changes the face of software development.  From C++ in the 80’s, to Java in the 90’s, to C# .Net in the 2000’s, each iteration transforms how people work and develop software systems.  Node.js is that language of the 2010’s, combining highly asynchronous development with a wide breadth of plugins to create 50%+ reductions in development time.  Its single-threaded execution, high-level of configurability, and large plugin ecosystem make it the ideal language for high-performance web application development.

C# Design Patterns: #3 – The Prototype

PrototypeWhat do CAD design tools, workflow automation, and digital audio synthesizers have in common?  They can all benefit from the Prototype pattern in their software architecture.

Although the Prototype pattern achieves true glory in languages such as JavaScript, which base their entire class structures on Prototypes instead of traditional classes, the pattern still brings powerful functionality to C#.  Its primary use is in a very specific niche: when the users of the application will perform design work, and then group those designs into reusable subcomponents.

jVectorMap – Creating Custom JavaScript Maps

jVectorMapBased on the jQuery framework, jVectorMap provides a convenient top-level map plugin for websites.  Although the plugin doesn’t have the full flexibility of Google Maps, it does provide a way to link countries or states to user interface actions.  With a wide suite of available maps, the ready-built package can suffice for most purposes.  On more advanced websites, however, it is sometimes necessary to create custom maps for additional geographic regions.

This is why most apps limit the width of any table to the width of the page. Still, at times it is necessary to show a large amount of data in a tabular format. This JavaScript scriplet will help add highlight functionality to any HTML table.

JavaScript Anonymous Functions – Blessing or a Curse?

Anonymous FunctionsThe growing popularity of AJAX and jQuery has significantly increased the use of anonymous functions in client-side JavaScript code.  Although anonymous functions provide a very convenient way to decrease the amount of code necessary in an app, their prevalence and necessity may portend to structural deficiencies in either the language or development tools.
