ometimes, it’s good to take ones understanding of a topic, throw it away and try to build a new mental model of it from scratch. I did that in the last couple of years with object orientation. Some things feel ever so slightly strange to let go of and re-evaluate.

Thoughts on HTML5 and Development Methodologies — JavaScript has serious limits. Compiling code from Java with GWT has many benefits. And most of the perceived limitations in this approach do not exist.

In my previous post, I glossed over our team switching from Python to Node.js. I kept it brief because the switch wasn’t the focus of the post, but since I believe I am being misunderstood, I will explain it in depth:

I’ve been using JavaScript for a while now, but only really programming in anger with it during the last year. I’ve found it in turns frustrating and enlightening, ridiculous and brilliant. I have never felt so empowered by a language and its ecosystem, so I thought I’d take some time to write about why that is. I’m starting with a ramble through the history of JavaScript, or rather my undoubtedly inaccurate understanding of it, to provide some context for where and how I’ve been using it.

Over the last … however many months I’ve been using Backbone, I’ve developed a number of opinions around building apps. I have a particular style of code that I write, with a particular set of functionality that is common through most of (if not all of) my apps. Backbone.Marionette is another of the many plugins I’ve created, that encapsulates my opinions.

jQuery form validation which helps you to do something new with your client-side validation code. jQuery is the popular Javascript library, you can include some cool effects in web applications with the help of jQuery. You can embedded it into PHP, ASP and HTML also. jQuery works with Ajax perfectly and lets you develop Ajax templates easily also.

In short words event delegation is the process to bind the events to parent element instead of binding events to all child elements. In Event Delegation we add such events on parent element only which actually binds to the child elements of the parent elements.

Today there are great opportunity in Web-development and Web-designing. Many wants to learn we-programming for earning, or as hobby. Below I’m describing the basic steps for novices helping them learn how to develop and design websites. This list may even help developers to get see through whats hot around web.

If and else statements are some of the more commonly used words in not only JavaScript but most modern programming languages. They fall under an umbrella of concepts that use terms such as conditionals or boolean logic. The terminology is not as important as what they actually do. They help your code decide between two or more potential paths. They have a basic principle, which is, if statement one is true to statement two, then run the following code before the if is closed.

Efficient management of the numerous lines of JavaScript code in web applications can be a challenge. Asynchronous JavaScript and XML (Ajax) interactions heavily populate pages to provide a better experience to the user. Single page interfaces, which are becoming more common, are driven by Ajax. Backbone is a JavaScript framework that can be used to create model-view-controller (MVC)-like applications and single page interfaces. In this article, learn how useful Backbone can be for creating Ajax applications or single page interfaces.

Ember.js is a new JavaScript framework that was formerly SproutCore 2.0. When I tried out SproutCore for the first time a few years ago, I was impressed with it’s data binding and templates, but I found it included a lot of things I didn’t need or want, like a large UI framework and it’s own recommended toolchain and workflow.

First video tutorial from a series that will be titled “HTML5 for App Developers”. The series will concentrate on app development aspects – so things like tooling/IDEs, debugging, HTML layouts, JavaScript frameworks, architectural and design patterns, and much, much more. The first video, which you can find in this post, is about Adobe Dreamweaver and how you can customize it to make it a more developer-centric tool/IDE.

Using the returned Deferred Object, and another useful utility function named $.when() we don’t have to stoop down to using poll-based techniques to wait for multiple animations to complete. Take a look at the code below and you will agree that it can be done much more cleanly now.

From Greg Brockman on Twitter: Web programming is the science of coming up with increasingly complicated ways of concatenating strings.

This is NOT a post for people who do not use MVC, Please delete your code, and write it properly.. Anyway, as anybody who has used or written a reasonable framework in PHP knows, MVC is pretty much the golden rule for implementation. There are a dozen frameworks out their based around the principles, with different levels of complexity.

There’s no doubt that Ajax is one of the most exciting, useful, and necessary web technologies available to front-end developers. Unfortunately, it’s also one of the most restrictive — especially when it comes to gathering content from other domains. Web developers are nothing if not persistent, so we’ve come up with a variety of ways to get around cross-origin restrictions, including JSONP, server-side proxies made with PHP, ProxyPass proxying, Flash transports, creative iFrame uses, and more. What many developers don’t know is that there’s a W3C specification called Cross-Origin Resource Sharing, or CORS, which provides a standard for cross-origin Ajax requests with minimal hassle.

Maybe you saw that tweet: “jQuery is a gateway drug. It leads to full-on JavaScript usage.” Part of that addiction, I contend, is learning other JavaScript frameworks. And that’s what this four-part series on the incredible Dojo Toolkit is all about: taking you to the next level of your JavaScript addiction. In this episode, we’ll take a tour of Dijit, Dojo’s UI library.

In this tutorial, we’re going to look at how easy it is to create scalable, robust and portable widgets using the latest version of the Yahoo User Interface library. YUI3 provides a Widget class for us to extend in order to create widgets in a consistent way that leverage the power of the library.

Do you know JavaScript and want to write a shell script? Then you should give Node.js a try. It is easy to install and shell scripts are a great way to get to know it. This post explains the basics.

In my last post on composite JS apps, I mentioned needing a search and search results section of my app. I’m starting off with a very simple search box that will let a user enter a name or description of an item, and the back-end server will return a JSON result set that I display on the screen. Since Backbone can encapsulate all of the server communication for me, I wanted to take advantage of this and set up a Backbone.Collection to do the search.

A standard video format in HTML 5 has not yet emerged. So as a web developer, to make sure you handle all major web browsers and that as many users as possible can see your content, you have to encode video in different formats and provide fallback options.

Applying CSS using jQuery: jQuery offers nice functions to work with css to read and set the css properties for page elements easily. .css( propertyName ) Gets the value of a css style property for the first matched element. Sample program to get the css property called 'background-color' for a div tag

In this post we had implemented simple Tooltips using JQquery and CSS.

We’re pretty fond of Mongodb at work and I’ve been getting an opportunity to kick some of the more interesting tyres recently. I thought I’d document something I found myself doing here, half hoping it might be useful for anyone else with a similar problem and also to see if anyone else has a much neater approach. The examples are obviously pretty trivial, but hopefully you get the idea.

Garbage collection. Aye? or Nay?

This series is going to walk through building a polished, functioning Windows Phone app from start to finish. The app is called Realworld Stocks and the full source code will be available on CodePlex as the series progresses. I’ll be using Mercurial to encourage forking and maybe even pull requests from developers who want to contribute their own real-world solutions.

I am currently working on yet another application. In that application I have two pages, the MainPage where I can choose a certain phrase. Choosing one of them navigates me to my second page, where I have three TextBlocks. The length of the text varies, depending on the phrase I chose in the first page.

I am developing an application for Windows Phone 7 and during tombstoning I had to store some data of the view model. Tombstoning is done in the code behind of the view in the “OnNavigatedFrom” and “OnNavigatedTo” methods

I think that the using statement in C# is a really nice invention. It’s an excellent syntactic sugar for handling IDisposables in a correct fashion. I get the impression that it took a while for the community to make it part of their daily routine to use it and now, as we are coming there, there is a shift towards asynchronous programming that may render the using block useless (or at least temporarily so, I hope to see C# 5 handling this in conjunction with the await keyword).

With Silverlight 4 out for over a year now, some amazing applications have been built with it. It's time to take a look at the next version now because it was just given the GA release this month! Time to update your skills.

One of the great things about Windows Phone is all of the samples that are out there. And topping them all is the Windows Azure Toolkit for Windows Phone 7 . The toolkit gives you everything you need to develop a Windows Phone application using Windows Azure. I will do a full post walkthrough of using the toolkit, but I thought I would post about one thing that seems to be tripping people up when they are trying to get things up and running.

In this post the author reviews how to get up and running the RavenDB, and .Net based document database.

While looking for a hint of interop unlock on a Dell Venue Pro device (running Windows Phone 7), I was working with the Engineering Mode application. One of the capabilities it offers is an AT command execution layer. While follwoing the list of Motorola-based commands, I selected a few that yield actual results.

The last post for our Getting Started week is one that might help us when we take our second step, when we might have gotten started and are now moving on and want to avoid running into a gotchas or two...

I don’t understand what all the fuss is about. The GUI in this app sucks. It’s hard to build reports, and it’s overpriced. $4.99?!? Save your money and get the free Access app instead.
