I have mainly been a Java guy throughout my 8 years as a software developer. For most of the applications I have written, I used the Spring framework or Java EE. Lately, I am spending time learning web development in Python, and one thing that has impressed me a lot is the Flask framework. The Flask framework is a micro-framework which makes it very easy to write REST backends. Today for my 30 day challenge, I decided to find a Java alternative to Python’s Flask framework. After doing some research, I discovered that the DropWizard framework can help me achieve the same productivity as the Flask framework. In this blog, we will learn how to build a RESTful Java MongoDB application using DropWizard.

Building Single Page Web Applications with Backbone.js, JaxRS, MongoDB, and OpenShift
Backbone.js is a mature, popular, and lightweight javascript library which aims to bring structure to your client-side code. The goal of backbone.js is to bring MVC, a software architecture pattern, to client side development.Actually, backbone.js is an MV framework where view is also responsible for controller logic as well. In this blog, we will build a simple social bookmarking application.
In brief, MVC is a programming design pattern for separating the different concerns of your application. The M corresponds to Model and is used to define domain object. The V corresponds to View and is responsible for display logic. Finally, the C corresponds to Controller and is responsible for user interactions and interactions between Views and Models.
You can find source code of the application here https://github.com/shekhargulati/getbookmarks. Backbone.js is used by Linkedin, Foursquare, Wunderkit, Groupon, etc to build complex applications. You can view the full list here.

How To Build Real-Time Location-Aware Applications using MongoDB , WebSockets , and HTML 5 GeoLocation API
One of the advantages of OpenShift or any other Platform as a Service is that it gives developers the power to turn their ideas into applications. As a developer, you are only concerned about writing code and the platform manages and scales the underlying infrastructure for you. I am also a developer and I love to write code.
A few days ago, I came up with a very simple idea to show messages in real-time on a map. A user posts a message via the application user interface, the application captures the user’s current location using an HTML5 Geo-location API, and then displays the message on a map. If another user posts a message from some other part of world, the first user will see that same message in real-time. As users start posting messages, they will see all of the messages appearing on the map.
