WEB 3.0: CUSTOMIZATION AT ITS CONVENIENT BEST

Web 3.0: Customization at its convenient best

The web industry today is all about adaptation and improvisation. With pioneers and intrepid thinkers constituting its vanguard, many tech enthusiasts understand and value this concept.

As part of the evolution and a result of an insatiable desire for more better, more convenient and more easier, this industry is on the verge of writing a new chapter in the annals of technical history called, “Web 3.0”. But before we delve into what web 3.0 is all about, let us take a look at its predecessors.

Contrary to web 1.0 websites, where the activity of a user was confined to mere passive viewing of available content, web 2.0 facilitated interaction and collaboration between users on social media platforms. These users were allowed to generate content, create and become a part of virtual communities which enabled them to break free from the restraints of web 1.0 that had until then prevented them from doing what they were now able to do with web 2.0.

Social networking websites, blogs, wikis, and video sharing sites are a few examples of web 2.0.

Shopping experience with Web 2.0:

Imagine this; you’re a diehard NBA fan and an ardent LA Lakers supporter. You know LA Lakers is coming to your town this weekend and will play a game at the local stadium. You have a couple of friends who’ve been planning to join you to watch the game. The typical practise would be that you’d browse the stadium’s website and buy tickets. After the game, you all wanted to go eat at a cool place, so you want to search for a nice restaurant near the stadium that is open till late night. You suddenly remember that your favorite player would be signing autographs and you want buy a Cap and a LA LAkers T-shirt so as to be signed. But except the T-shirt, you need to buy the hat and a life size poster of player you want autographed. So you visit some more websites to sort out store(s) that sell the merchandise you’re looking for.

The bottom line is, you end up visiting numerous websites that takes a lot of your time and effort to zero in on what you exactly want.

Web 3.0 Mantra: The more you browse the web the more the web learns about you, your needs and your preferences.

Transforming the shopping experience with Web 3.0: The concept of Web 3.0 is based on two important aspects: Requirement and Users. Requirement is the reason why User is on the internet in the first place.

Now, in a Web 3.0 enabled browser, all you might have to do is type in a sentence like “I’m a Lakers fan and I want to watch this Friday’s game and after that dine out with four of my friends in a nice restaurant nearby.” Your request will be analysed by the Web 3.0 browser, it will then search the internet for all possible answers and then organize them in a way that suits your requirements best. Voila! As many experts have started calling it, you now have your very own “Personal Assistant”.

This means that with time, you would have the luxury of being less meticulous and specific yet get what you really want. With time, you might just ask “When’s the game?” your Web 3.0 browser would skim its records of your preferences, consider your current location and display a list of customized and accurate-almost-to-the-T suggestions of the cheapest available tickets, restaurants nearby, merchandise stores nearby and detailed information about any pre game or postgame Lakers team activity.

The contemporary web search engines look for webpages that contain the keywords you’ve entered. This means that the search engine hasn’t completely understood your request and is unsure if the webpages suggested are relevant to your topic of interest. A Web 3.0 search engine however, would not only consider the entered keywords but also understand your actual requirement. Web 3.0 would treat the whole internet as an enormous database of information readily available to answer any query.

Web 4.0: The next wave

Even though Web 3.0 is still in theory and its nascent stage, it still hasn’t prevented those with a profound flair for innovation to think about what would be after Web 3.0. Welcome to the not-in-the-so-distant-future Web 4.0. Web 4.0 has been characterized by experts as the Web OS. With the entire web being one single operating system, it enables flow of information from any given point to another. This shall be a groundbreaking advance in technology that would set precedents in the field of connected data. A bond between two completely different sectors shall be so seamlessly forged and needs that we didn’t even know we had, would be fulfilled.

Watch out for your own web-based “Personal Assistant”! Keep Browsing!

EXPLAIN THE BIND() METHOD IN JAVASCRIPT?

Explain the bind() method in JavaScript?

We use the Bind () method primarily to call a function with the this value set explicitly. It other words, bind () allows us to easily set which specific object will be bound to this when a function or method is invoked.

The this value in methods and functions must be set explicitly when you need a specific object bound to the function’s this value.

The need for bind usually occurs when we use the this keyword in a method and we call that method from a receiver object; in such cases, sometimes this is not bound to the object that we expect it to be bound to, resulting in errors in our applications.

WHEN DO WE USE $APPLY() IN ANGULAR? IS IT A GOOD PRACTICE TO USE?

When do we use $apply() in Angular? Is it a good practice to use?

$apply() is used to execute an expression in angular from outside of the angular framework. (For example from browser DOM events, setTimeout, XHR or third party libraries). Because we are calling into the angular framework we need to perform proper scope life cycle of exception handling, executing watches

We use it very rarely. AngularJS actually calls almost all of your code within an $apply call. travel Events like ng-click, controller initialization, $http callbacks are all wrapped in $scope.$apply(). So you don’t need to call it yourself, in fact you can’t. Calling $apply inside $apply will throw an error.

HOW DO JAVASCRIPT CLOSURES WORK?

How do JavaScript closures work?

A closure is an inner function that has access to the outer (enclosing) function’s variables—scope chain. The closure has three scope chains: it has access to its own scope (variables defined between its curly brackets), it has access to the outer function’s variables, and it has access to the global variables.

The inner function has access not only to the outer function’s variables, but also to the outer function’s parameters. Note that the inner function cannot call the outer function’s arguments object, however, even though it can call the outer function’s parameters directly. You create a closure by adding a function inside another function.

Closures have access to the outer function’s variable even after the outer function returns.

Closures store references to the outer function’s variables.

Closures have access to the updated values of the outer function’s variables, they can also lead to bugs when the outer function’s variable changes with a for loop. To fix this side effect (bug) in closures, you can use an Immediately Invoked Function Expression (IIFE).

IN CSS, WHAT DOES IT MEAN BY FLOATING ELEMENTS – HOW TO USE THEM, TROUBLES WITH THEM, AND HOW TO WORK AROUND THE TROUBLES?

In CSS, what does it mean by Floating elements – how to use them, troubles with them, and how to work around the troubles?

Float property can be used to align an entire block element to the left or right such that other content flows around it.

For instance, Float is used for wrapping text around images or create table-like columns in an HTML layout without the use of tables.

The most common problems of float-heavy layouts are:

The “collapsing parent”.

(a) Fix 1: one of the most common ways to fix a collapsed parent element is to place an element with the clear property after the floated element. This will cause the parent to begin reflowing after the floated element.

(b) Fix 2: There is a method that allows a parent element to clear itself of any floated elements inside it. It uses a CSS property called overflow with a value of hidden. Note that the overflow property was not intended for this type of use, and could cause some issues such as hiding content or causing unwanted scrollbars to appear.

In IE 7, the Bottom Margin Bug is when if a floated parent has floated children inside it, bottom margin on those children is ignored by the parent. Quick fix:using bottom padding on the parent instead.

HOW PREDICTIVE ANALYSIS IS GETTING POPULAR?

How Predictive Analysis Is Getting popular?

There is a fine yet conspicuous difference between a successful web business model and a successful and sustainable web business model. In case of a web business that aims to sustain and succeed, which is what every business owners would love to achieve, the same metrics are to be incorporated but, with the addition of foresight. This foresight or predictive analysis is what that is necessary for a business to sustain, develop and prosper in the upcoming future.

Predictive Analysis is the technique that involves mining of data and analysis of statistics to give a prediction of future user behaviour, trends, events etc. This technique clears the mirages ahead of web businesses and gives them a clear view of what lies ahead so that mistakes are avoided and adjustments in tune with the upcoming events are made in time.

Companies that benefited with Predictive Analysis Techniques:

A lucid example of predictive analysis can be found in Facebook’s news feed. In its nascent stage, Facebook’s news feed feature used to display updates of all of a user’s friends in a chronological order. However, the news feed now prominently features updates from those friends/family with whom the user interacts most. This is due to the wave of the predictive analysis wand that resulted in the creation of an algorithm that predicts which stories a user might be interested in, based on most frequent interactions and profile details.

An aspect of Amazon where the implementation of predictive analysis is ubiquitous is the recommendations that one sees on the website. These recommendations are smartly displayed to users compelling them to view more and consequently end up purchasing more. The cause behind this smart display and effective business tactic is a diligent analysis of user behavioural patterns and terabytes of scattered data.

Predictive Analysis Techniques:

Predictive Analysis encompasses a number of techniques that are employed to know about the likelihood of events, assessment of user behaviour and probable consequences for a range of decisions.

These techniques are broadly classified under

  • Predictive : Deals with the assessment of probable customer behaviour.
  • Descriptive: Deals with the analysis of past performances and patterns.
  • Decision Models: Describes the relationship between all of a decision’s elements and its variables to foresee the results of those decisions.

Making the most of Predictive Analytics to improve conversion rates:

Predictive analytics factors in all possible variables that help the marketer devise the right strategy to generate the desired engagement with customers – from providing timely and accurate sales forecasting insights, to equipping them with opportunities to improve diagnosis.

predictive analysis techniques

These insights can range from

  • What time of the day your website can witness maximum traffic - This lets owners monitor their incoming traffic by knowing what time most visitors are hitting their website. These insights might be useful to offer special coupons for online store to drive sales and help target the right audience for their business.
  • What products/pages will receive high impressions - Here we can find out where sales are really coming from and see which of your marketing efforts are giving the best return on investment, with insights that show your traffic and revenue by channel.
  • Which region you can expect the bulk of the orders to come from - Perhaps this is an effective approach for companies with large national or international markets because different consumers in different regions have different needs, wants and cultural characteristics that can be specifically targeted at creating niche segments to promote and sell their products or services.

As in the case of any other technique, system or ideology, Predictive Analysis is not flawless and perfectly accurate either. It must always be remembered that though predictions are made and probabilities seen on the basis of scientific reasoning and logical analysis, they still remain an “Analysis”, a “Probability”. Their limitations not withstanding, this technique is no longer the prerogative of renowned industry stalwarts but is being implemented by small, large companies and unicorn start-ups alike.

AGILE METHODOLOGY-DRIVING FORCE BEHIND SOFTWARE DEVELOPMENT

Agile methodology is continuing to be a Driving Force behind Software Development

Agile methodology is a collection of software development strategies in which requirements are obtained through collaboration between self organizing teams. It is a term that was derived from the Agile manifesto, which was written in 2001 by a technical group that included developers of Scrum, Extreme Programming and Dynamic Systems Development Method. The Agile process promotes and requires that functionalities with higher business value are done first.

Agile methodology

Popularity of Agile methodology:

According to a study conducted by Version One, Technology Company known for development of Agile lifecycle management software, 94 percent of business organizations in the world are practicing Agile. It is quickly becoming the de facto standard of software development and Agile will become the best practice of software development in the next ten years. Acceleration of product delivery, accommodation of change and driving of productivity are the main reasons for the high popularity of Agile methodology. Connoisseurs of web development believe that Agile methodology is all about delivering value to the business on a repeatable, reliable and rapid fashion.

Transitioning from waterfall to Agile:

The advantages of Agile over Waterfall are conspicuous and businesses, whose very success depends on making the most advantageous decisions, are flocking to the Agile methodology. In a plethora of companies that have been baptized as Agile in recent times, Toyota is a brand that deserves a detailed mention.

The name Toyota has become synonymous with fast, efficient, luxurious and dependable automobiles. What most of us don’t know is that Toyota does not just make cars, it also develops its own software. The folks at Toyota understand the importance of automatic electronic control system which is why the Project General Manager from the Automotive Software Engineering Department, Mr. S. Ishii referring to the importance of developing software for their cars, said that “Toyota needs to become an IT company”. Mr. Ishii said that they would probably be shifting their approach from Waterfall to Agile.

He stressed on the importance of detecting bugs early in the development cycle to prevent expensive rectifications. A defect detected in the prototyping stage is 50 times less expensive than if it is discovered in the production phase. The defect will be dearer by 1000 to 10000 times if it is discovered after the production phase. The fact that Toyota is incurring a cost of 2 billion dollars due to recalls and lost sales that were the result of a software glitch in the braking system of their Prius model has made them think of how important prompt detection of issues is. This made them transform from waterfall to Agile.

How Agile & Scrum go mainstream?

As Agile does not provide concrete steps, organizations seek more specific methods within the Agile environment including crystal clear, extreme programming, feature driven development, dynamic systems development method and Scrum. Scrum gives special importance to decision making from real time scenarios rather than speculation. It can be defined as a simple set of roles, responsibilities and meeting that never ever changes.

agile & scrum methodology

12 Principles of Agile Development Manifesto:

  • Customer satisfaction by rapid delivery of useful software
  • Welcome changing requirements, even late in development
  • Working software is delivered frequently
  • Working software is the principal measure of progress
  • Sustainable development, able to maintain a constant pace
  • Daily cooperation between business people and developers
  • Face to face is the best form of communication
  • Projects are built around motivated individuals who should be trusted
  • Continuous attention to technical excellence and good design
  • Simplicity is essential
  • Regular adaptation to changing circumstances

Scrum is an iterative development process and projects progress via a series of iterations called sprints. It does not include any traditional software engineering roles such as programmer, designer, tester and architect. The scrum team forms a common ownership of the work to be performed rather than just focusing on particular task.

While scrum is the most popular example that encapsulates agile philosophy, there are a number of Agile techniques available including pair programming, test driven development and continuous integration.

Overall, Agile manifesto deals with four core values of individuals and their interactions, delivering working software, customer collaboration and high performing teams which is the reason it’s continuing to be a Driving Force behind Software Development.
