Overview About Data Visualization?

What is Data Visualization ?

Data visualization is the presentation of data in a pictorial or graphical format. For centuries, people have depended on visual representations such as charts and maps to understand information more easily and quickly.

Data visualization is a general term that describes any effort to help people understand the significance of data by placing it in a visual context. Patterns, trends and correlations that might go undetected in text-based data can be exposed and recognized easier with data visualization software.

Data visualization is important because data on its own can be boring and hard to understand. Imagine
reading row after row of little numbers and you'll soon get the idea. Data visualization helps present that
information in a way that's engaging and helps communicate complex ideas quicker. This is especially
true on the web, where data visualization can grab a web surfer's eyes and get information across much
easier than paragraphs and paragraphs of words.

The main goal of data visualization is to communicate information clearly and effectively through graphical means. It doesn't mean that data visualization needs to look boring to be functional or extremely sophisticated to look beautiful. To convey ideas effectively, both aesthetic form and functionality need to go hand in hand, providing insights into a rather sparse and complex data set by communicating its key-aspects in a more intuitive way.

Data visualization is closely related to information graphics, information visualization, scientific visualization, and statistical graphics.

Why is data visualization important?

Visualizations help people see things that were not obvious to them before. Even when data volumes are very large, patterns can be spotted quickly and easily. Visualizations convey information in a universal manner and make it simple to share ideas with others.

About Augmented Reality?

What is Augmented Reality?

Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data.

Augmented Reality is a type of virtual reality that aims to duplicate the world's environment in a computer. An augmented reality system generates a composite view for the user that is the combination of the real scene viewed by the user and a virtual scene generated by the computer that augments the scene with additional information.

Augmented reality (AR) is the integration of digital information with live video or the user's environment in real time.

Experiencing Augmented Reality ?

Three Simple Steps:

1)Recognition: Recognition of an image, an object, a face or a body
2)Tracking: Real-time localization in space of the image, object, face, or body
3)Mix: Superposition of a media (video, 3D, 2D, text, etc…) on top of this image, object, face or body.

Advantages

1)Anyone can use it.
2)Knowledge, information increments are possible.
3)Experiences are shared between people in real time.
4)Video Games provide an even more “real” experience.
5)The mobile user experience will be revolutionized by AR technology as did gesture and touch (multi-modal interaction) in mobile phones.
6)Mobile usability is improved by AR acting as the primary interface.

Disadvantages:

1)Spam and Security.
2)Social and Real-Time vs. Solitary and Cached.
3)User Experience: Socially, using AR may be inappropriate in some situations.
4)Interoperability.

Introduction about Web Scraping?

What is Web Scraping?

Web scraping (web harvesting or web data extraction) is a computer software technique of extracting information from websites.

Web scraping is closely related to web indexing, which indexes information on the web using a bot or web crawler and is a universal technique adopted by most search engines.

Web Scraping refers to an application that processes the HTML of a Web page to extract data for manipulation such as converting the Web page to another format (i.e. HTML to WML).
Web Scraping scripts and applications will simulate a person viewing a Web site with a browser. With these scripts you can connect to a Web page and request a page, exactly as a browser would do.

What is Web Scraping Service?

Web Data Scraping offers affordable 100% risk-free, and accurate web scraping service , data extraction/scraping, text parsing, screen scraping, web data extraction, and website scraping and custom scraping development service to large companies as well as medium size companies which need data to be processed.

Introduction about CDN

What is CDN?

CDN Stands for Content Delivery Network.
A content delivery network (CDN) is a system of distributed servers (network) that deliver webpages and other Web content to a user based on the geographic locations of the user, the origin of the webpage and a content delivery server.

A content delivery network (CDN) is an interconnected system of cache servers that use geographical proximity as a criteria for delivering Web content.
In a CDN, content exists as multiple copies on strategically dispersed servers. A large CDN can have thousands of servers around the globe, making it possible for the provider to send the same content to many requesting client computing devices efficiently and reliably

Benefits of CDNs

Eliminate Pauses and Accommodate Heavy Traffic
Minimize Packet Loss
Faster Loading
File Mirroring
Optimize Live Delivery
Enable Linear Networks
Support Video on Demand
Scalability

Disadvantages of CDNs

New Points of Failure
Sharing Resources
Geographical Choice Considerations
Content Management Problems
Lack of Direct Control

Popular CDN Providers

Akamai
Amazon CloudFront
BitGravity
CacheFly
CDNetworks
CloudFlare
EdgeCast
EdgeStream
Limelight Networks
LocalMirror
MaxCDN
Mirror Image
Panther Express

Some types of sites will almost always benefit from a CDN:

1)Sites streaming large video files
2)Sites which consist of mainly large media files like image sites
3)Sites which have known heavy traffic in different countries

Some sites almost never need a CDN:
1)Local business sites (restaurants, beauty parlors, etc.)
2)Sites that have their main traffic in one geographic area or region

How do you set a CDN up?

The main steps for setting up a CDN are

Signing up for a service
Know what files you are using
Getting your files to the CDN servers
Decide on how to name your urls (CNAME)
Ensuring your webpages are calling (using) the files you sent to the
CDN
Testing

Small Introduction about Rest API?

What is REST API?

REST stands for Representational state transfer.

It relies on a stateless, client-server, cacheable communications protocol -- and in virtually all cases, the HTTP protocol is used.

REST is often used in mobile applications, social networking Web sites, mashup tools and automated business processes. The REST style emphasizes that interactions between clients and services is enhanced by having a limited number of operations (verbs). Flexibility is provided by assigning resources (nouns) their own unique universal resource indicators (URIs).

REST involves reading a designated Web page that contains an XML file. The XML file describes and includes the desired content.

The REST architectural style describes six constraints. The six constraints are:

Uniform Interface
Stateless
Cacheable
Client-Server
Layered System
Code on Demand

RESTful applications use HTTP requests to post data (create and/or update), read data (e.g., make queries), and delete data. Thus, REST uses HTTP for all four CRUD (Create/Read/Update/Delete) operations.

REST is a lightweight alternative to mechanisms like RPC (Remote Procedure Calls) and Web Services (SOAP, WSDL, et al.).

REST is not a "standard". There will never be a W3C recommendataion for REST, for example. And while there are REST programming frameworks, working with REST is so simple that you can often "roll your own" with standard library features in languages like Perl, Java, or C#.

As a programming approach, REST is a lightweight alternative to Web Services and RPC.

Much like Web Services, a REST service is:

Platform-independent
Language-independent
Standards-based (runs on top of HTTP), and
Can easily be used in the presence of firewalls.

Like Web Services, REST offers no built-in security features, encryption, session management, QoS guarantees, etc. But also as with Web Services, these can be added by building on top of HTTP:

For security, username/password tokens are often used.
For encryption, REST can be used on top of HTTPS (secure sockets).... etc.

Overview About Responsive Web Design

What is Responsive Web Design?

Responsive Web design is an approach whereby a designer creates a Web page that “responds to” or resizes itself depending on the type of device it is being seen through. That could be an oversized desktop computer monitor, a laptop, a 10-inch tablet, a 7-inch tablet, or a 4-inch smartphone screen.

Responsive Web design has become one of the hottest trends in 2013. This is due in part to the growth of smartphones and other mobile devices. More people are using smaller-screen devices to view Web pages.

The purpose of responsive design is to have one site, but with different elements that respond differently when viewed on devices of different sizes.

How Does Responsive Web Design Work?

Responsive sites use fluid grids. All page elements are sized by proportion, rather than pixels.

So if you have three columns, you wouldn’t say exactly how wide each should be, but rather how wide they should be in relation to the other columns.

Column 1 should take up half the page, column 2 should take up 30%, and column 3 should take up 20%, for instance.

Media such as images is also resized relatively. That way an image can stay within its column or relative design element.

What is responsive design?

A responsive design simply means a website that has been constructed so that all of the content, images and structure of the site remains the same on any device. For example, when a user accesses a site on their desktop, they are getting the full view of the site. But when that same user goes to visit the site from their smartphone or tablet, the site will retract to fit on the smaller screen.

In other words, with a responsive website design, you don't have to have worry about having different websites for various devices or making sure that your site runs properly on a mobile device.

But there are some other really important reasons why you should make the switch to responsive design for your website.
