Deep Research and Development

I wanted to start this blog by a quick overview of current state of Big Data playground. There was a lot of noise during this year from everywhere making it nearly impossible for a newcomer to learn this world without being overwhelmed. So let's start. How does Big Data differ from NoSQL? NoSql is a type of database, which provides a mechanism for storage and retrieval of data modelled in means other than the tabular relations used in relational databases. The most prominent representatives are Cassandra ,  MongoDB ,  Neo4j and Redis each taking a different approach in data representation. It is important to notice, that NoSql databases have nothing to do with the amount of stored data, but merely it's representation. On contrary Big Data is commonly referred to technologies used to store and operate on huge amounts of data. Usually it is referred to a Apache Hadoop  ecosystem. In fact Hadoop it's file system based databased, so it's also NoSql database. However if Re...

The JavaScript language is simple and straightforward and often there’s no special syntax for features you may be used to in other languages, such as namespaces, modules, packages, private properties, and static members. For this reason, a lot of ambiguity lingers thought the streets of JavaScriptville. Namespaces Before we start creating classes, I would like to introduce the concept of namespaces. Namespaces help reduce the number of globals required by our programs and at the same time also help avoid naming collisions or excessive name prefixing. JavaScript doesn’t have namespaces built into the language syntax, but this is a feature that is quite easy to achieve. We'll create a global function, which will create a namespace according to the received fully qualified namespace name (e.g. JsDeepDive.Common.Managers). We'll iterate over each segment of the namespace and create namespaces where are needed. Full implementation looks like this: function namespace(names...

So you've heard everyone talking about this mythical creature called Bower. But what exactly is it? Better to see once than to hear 100 times, so before we proceed any further take a peek at their  site . The problem Recall how you used to manage, and maybe still do, your 3rd party libraries. Firstly you went to their official site or maybe github repository. After finding the latest minified version, you would  get something like this - xxx-1.0.1.min.js, then  downloaded and saved it into your project. At last referencing it in the HTML would do the trick by copy pasting the script tag - <script src="//code.jquery.com/jquery-1.11.0.min.js">. But what would have happened if a new version came up? Well, if you were aware of the update, you would repeat the process again and put xxx-1.0.2.min.js in your library folder. Then you would change the reference in your HTMLs or JavaScript files. You could of course rename the file to xxx.js and omitting the version...

The world has changed as it must. JavaScript developers are no longer considered the outcasts of developer community, but a boutique club gaining followers like no one else. However with its popularity and chic, comes the complexity and burden of maintenance. A JavaScript developer can no longer write one's code in a text editor and rely on ad-hock solutions copy pasted from various forums, but surround oneself with professional tools specifically designed and customized for the language. In this article, I'll present  must have  tools, which will assist any JavaScript developer in the crafting of awesomeness. Environment Your OS is largely dependent upon our habits or company's policy, however for server side developers, I would strongly suggest migrating towards Unix base OS like OS X or Linux of some sort - my preference is Ubuntu. The reason behind the choice is the enviroment on which your node.js application runs on, which is Unix machine. The sooner you work on the c...
