Mobile application and internet penetration

From year 1992 many things changes ranging from the cold war to a new era of telephones and off course Internet, it was also a year where IBM unveiled the very first smartphone. Fast forward two years and the device officially hit the market for a cool price of $1,100 a pop. And after only six months, it had sold over 50,000 units.

  Fast forward to the year 2021, Apple has launched a phone that cost almost the same as IBM but offers things that were an alien thing to The old IBM smartphone.

 Smartphones without the apps and their interface is just a mere tool, there are end-less usage and purpose of the application available for the smartphones; whether one uses it for fun or work, there will be a dedicated app for it. Apps require data to be accessible and due to this Data usage per subscriber in India, jumped by around 43 times in just six years while data cost decreased by 96% (by 24 times) compared to 2014. On average Indian users consume around 14.4 GB of data in a month, and it continues to increase making India the second-highest in the world.

Internet services

 

Some examples of the smartphone application that consumes data are:

Social media and communication 

The ability to keep up with the world’s happening is important in the 21st century. Social media apps like Facebook, Twitter, Instagram are not only common but specialized apps dedicated to checking the news, connecting to people and friends via instant messaging. Social media and communication apps are emerging as nothing else, and this is because of the pandemic. Pandemic gave rise to online education that is only possible with telecommunication apps. Online education or E-learning increased the demand for data usage to a greater extent. E-learning uses apps like Zoom, Google meets, and many more to educate the masses, and recent studies have shown that the data usage on average is between 11.24MB – 17.28MB per minute on Google meets and Zoom, and the longer the meeting duration, the greater the data usage. This explains the growing use of the internet in this 21st century.

Gaming app and Internet

The one thing that has flourished during this isolation free-time is none other than Esports or E-gaming, but the pandemic acted as a Catalyst for the Esports industry to grow and flourish. Lockdown came with a lot of free time, and the source of entertainment was limited. Hence, it proved itself to fight boredom. During the pandemic, most of the students preferred interacting over games like PUBG, Call of Duty, Free Fire, Mini Militia, and several other games, Games like PUBG, Call of Duty, and Free Free Fire, works on the principle of gaming along with interaction, which needs more data and creates Data explosion or internet penetration.

Entertainment and OTT platforms

The whole pandemic came with social isolation, and it is one thing that requires interaction and socialization. The Movie theatre, the pubs, and restaurants were all closed due to the COVID scenario,  acted as a catalyst for the flourishment of OTT platforms like Netflix, amazon prime, and ZEE5.

As of now, India stands third in the total revenue generated by OTT platforms. Over the few decades, internet penetration is happening at an astonishing rate. Apps like Youtube, Amazon Prime, Netflix are used by almost 50% of the general population, and this is causing them to enjoy the treat with both the number of users and views surging on their platform 

Work-from Home culture

Google Meet, zoom, and sites like We Work Remotely, Jobspresso, FlexJobs worked as a facilitator for Internet Penetration. The telecom industry saw an overall surge of 10 percent traffic as more and more offices are switching to work from home. The Lockdown became a blessing for the broadband sector as the Subscriptions to fixed broadband, especially in the urban areas, have surged because millions are working from home that caused the increase in data usage percentage.

Aside from the application perspective of internet usage surge, one more component that contributed to the penetration of Internet is,

The low Internet Rate

India currently consume almost 12 GB per month, but it was not the case in early 2000s. Most regions in the early 2010s relied on 2G technology, and only 9% of the rural population had reliable internet access. JIO was launched in 2016 that gave rise to a cheaper data environment that offers fast speed. Due to all this, India’s access to the internet in rural areas has tripled since 2015.

Furthermore, the average internet user went to 11 GB from what it was i.e., 700MB. The internet is available at a rate that starts as low as 1$ a month.

Conclusion

Internet penetration didn’t happen overnight but was a slow and gradual process. The points mentioned above are just a few examples that prove the internet penetration

Most Widely Used Django Packages

 

Django and its packages

Django is a web framework that uses Python to create a web design. The main goal of Django is to write a dynamic website. It came into existence in 2003 under a press agency of Kansas, Lawrence.

The slogan of this framework already describes the explicit nature of this framework “The web framework for perfectionists with deadlines”, Django allows the web developer to create an efficient web application in a short period.

django web Related book

Capabilities of Django

  • versatility: Any type of website can be built with Django, It can work as a client-side framework as well as the user-side framework, Django delivers the content in almost any format such as HTML, XML, etc.
  • Scalability: when talking about Django, its main USP is scalability, Django web nodes have no stored data means they scale horizontally.
  • Portability: Django codes can run on any platform such as Linux, Windows, and Mac OS, due to the framework written in Python.
  • Security: Mostly considered as hacker-proof.

for better understanding of this Django framework refer https://techvins.com/blog/django-web-development/

Django is best suitable for back-end projects and we can’t forget the packages that make the Back-end development easier to handle

 What is Packages in Django and how it helps in Web development?

Package refers to a collection of modules. A module is a single python file and a combination of such python modules makes up the package. A package contains a file _init_.py that distinguishes it from other python files.

 Like the framework, Django is best suitable for back-end projects, One can’t outlook the importance of packages in web development. So here are some of the packages available for the Django framework.

  • Django-Rest-Knox:

A token-based tool used for the authentication of Django REST framework. Knox allows common pattern in the REST based application to ensure the connections security. It allows client to have one token, that gets deleted when the user logs out. https://github.com/James1345/django-rest-knox

  • Django-Allauth

When one is suffering from address problem, authentication problem, registration related issue and problem-related to accounting management, Django Allauth solves the purpose. Allauth fills the gap between local and social authentication 

  • Django-celery

  • Celery is a asynchronous task job queue-based tool that works on distributed message passing. It focuses on real-time operation and even supports the scheduling of the task. Scheduling of the task is very easy with celery. Django-celery provides celery integration for Django using ORM and cache backend for storing the results.
  • Django-configurations

 Django-configurations eases Django project configuration by relying on the composability of Python classes. It further extends the notion of Django’s module based settings loading with well-established and object-oriented programming patterns. To use it one has to modify the manage.py or wsgi.py script.

  • Django-Rest-framework 

The package that writes a REST architectural constraints API with proper, autogenerated documentation that also supports implementing packages in projects. The auto-generated documentation is of great help because it always changes with endpoints.

 

Django-extensions

A tool that can help you with your daily work. Django-extension command shell_plus runs Django shell with preloaded files.

  • Django-rest-framework-jwt

JSON web token is a open standard tool mafefor  transferring data securely within the parties using a JSON object. JWT token becomes necessary when dealing with DRF for some projects. Its main job is to implement and manage authentication tokens for API, and The maintenance session is on the client-side instead of the server-side.

  • Django-rest swagger:

When looking for a tool that creates nice documentation out of the DRF API, then look no more, Django-rest swagger is there for you. The main feature of this package is its auto-generated documentation which makes the document look nicer.

 

  • Django-Redis

Redis, a in-memory data structure that is also used as a caching engine. Since it keeps the data in RAM, Redis delivers the data very quickly. Likewise there is one another popular cahcing system Memcached, which is a competitor of redis, however redis always have the better features. 

  • Django-simple history

 Then comes the Simple history, It is responsible for storing Django model state on every create, update, and every delete consequently. Simple history above all works by creating a separate “historical model” for each model that requires an audit trail.

 

  • Django-FSM:

Django-FSM adds support to finite state machines of the Django models, it is capable to run and process through states like Writing, Editing, and Published, Django-FSM helps in defining those state and manage the rules around moving from one state to another.

Conclusion

       Lastly I want to conclude In-brief that choose the Django stack package accordingly

Python Packages for web Development

With most of the world being digitalized, It becomes somewhat necessary to know about AI and its parts, this problem can be resolved by a beautiful piece of a tool known as Python and python packages, now Python was designed in December 1989, Python’s creator was looking for a hobby project to keep him occupied in the week around Christmas. He was thinking of writing a new scripting language that’d be a descendant of ABC and something that can attract the hacking population. He chose to call it Python because he was inspired by a popular British troupe i.e., Monty python.

A python code

Python serves as a general-purpose, programming language that boasts an impressive library for data processing. Python’s best feature is its code readability which makes the language user-friendly and easier to use, the feature that makes python a reliable one is its simple syntax and shortcode length. Python as a language is an interpreted, object-focused, high-level language with semantics dynamic in nature. Its data structure combined with its dynamic typing make it very appealing to the programmers, as well as for the use as a glue language connecting existing components. Python emphasizes readability which then reduces the cost of the program maintenance. for more info about python https://techvins.com/blog/web-development-and-its-terms/

Django Web-development, A beginners guide

Web 2.0 came as a blessing for the modern era of web designing, It also brought up many technologies ranging from server side language to Django i.e., a client-based language as well as server-side language:

  • The server-side language, which is Java server page (JSP), PHP, and many more
  • The database also came with web 2.0, which stores a lot of information that can be used to authenticate users or display an item from older to recent entries.
  • Client-side language or Back-end language, is a language that works to make sure that everything on the client-side works fine.

       And from this side of web development, Django emerged, It is a web framework that uses Python to create a web design. The main goal of it is to write a very fast website that is dynamic. It came into existence in 2003 under a press agency of Kansas, Lawrence.

 

The slogan of this framework already describes the explicit nature of this framework “The web framework for perfectionists with deadlines”, it allows the web developer to create an efficient web application in a short period.

Django Architecture

The framework of this python based language is focused on MVT ( Model-View-Template) architecture, which is a software design used for developing a web application.

The model works as the interface of the data, and it is the logical structure behind the website or app generally represented by a database.

The view is the user interface usually represented by CSS/HTML.

The Template in this MVP architecture consists of static parts of HTML outputs and syntax, which describes how dynamic content will be installed. 

Django code

Beginners Installation Guide,

-Install Python using the latest version of it

Moreover, when talking about the project ideas for Django, we can’t forget packages, Here are some packages associated with This framework include Django-Rest-Knox, Django-Allauth and for more detailed intro to the packages refer https://techvins.com/blog/most-widely-used-django-packages/

This was the server-side part of Django, and when talking about an application the data from the user side is very much essential, and for that form comes into play. Forms are a big part of the internet and one of the primary sources for the user to submit data to servers.

 Working with Forms 

 Consequently Django provides multiple tools and libraries to help the developer build form that accepts input from the site visitors. It’s form functionality can simply do most of your work and can do it more securely than other programs available.

the work of it that is involved in forms are:

. to prepare and reconstruct data to make it renderable.

. Subsequently it create the HTML form for the data

. Besides all this, it receives and processes data from users.

 Some common questions associated with the framework and its uses

What organization manages Django

Django web framework is managed and maintained by an independent, non-profit organization named Django Software Foundation (DSF), whose primary foundation goal is to promote, support, and advance the  Web framework.

What makes it suitable for the development of my site?

 . For instance, its Stability and reliability makes this web development system so appealing and not to mention functional.

. Scalability:  Another USP of this framework is its scalability, and for this reason it is so useful, Django web nodes have no stored data means they scale horizontally.

. Speed: It is python-based, so ideal for quick and effortless building.

Disadvantages associated with Django?

  • The framework modules are However bulky.
  • Furthermore it is completely based on its ORM.
  • Components  deployed together.
  • You must certainly know the full system to work with it.

Is it a new web development system?

Of course, it is a new web development system and its history that came into existence in 2003 under a press agency of Kansas, Lawrence. Although the web framework is managed and maintained by an independent, non-profit organization named Django Software Foundation (DSF).

Web Development and Its terms

Website development generally refers to the work that goes into building a website and maintaining it. Website development includes aspects such as web design, web programming, web publishing, and database management. and it is of so much importance due to expanding nature of the IT industry. Between now and 2028, the employment of web developers is expected to grow by 13%. That’s much faster than most other technology careers, and this is solely due to the increase of internet consumption among individuals.

the web developer working on a project

The term web development is made up of two words & i.e.,

Web: To think of it in its simplest terms, the web is a collection of websites, webpages, and anything that we see on the internet and the internet is a network of cables that facilitates the transmission.

Development: Creating anything from the scratch.

When we talk about the web development tool, we generally talk about any tool that makes the particular project run effortlessly and efficiently.

Things to consider while choosing a development stack for your Web development career.

Complexity: the more the complexity of the delivery, the more will be the complexity of the developmental tool.

Security: Security should never be compromised with anything, and when it comes to web development it becomes a necessity.

Scalability: Consider the developmental tool according to the need for the scalability of the project.

Cost: If the budget is involved in the project, try to have a look at what might be the best tool fitting in the budget

so these were some points to consider before purchasing your next web development tool

The two different sides of web development

Front-end development:

Commonly known as client-side development, primarily produces HTML, CSS, and JavaScript for a website or Web Application so, that the individual surfing through the browser can see and interact with them directly. The main objective behind the Front-end development is to ensure that when the users open up the site they see the information in a format that is easy to read and relevant.

Back-end development

The server-side of the website, which works to make sure that everything on the client-side works fine. Two parts make up the back-end of a website: the database and the application. the database stores all the information of the website, and the application works as a middle-man coordinating between the front-end and the database. The back-end is one part of the website one can not see or interact with. It is the portion of software or website that does not come in direct contact with the users. Back end development also include Django  framework which is very useful for mastering the back-end projects

Now, let us look at the terms which are usually associated with web development.

Chrome DevTools:

The tool mainly used for debugging, iterating the profile of the site, The chrome Devtool are set of web authoring and debugging tools that are built-in google chrome.

. Sketch:

When dealing with the design element for the site, The search of it stops on something called Sketch. The sketch is a design toolkit for your site and also features the ability to add clickable prototypes and simple animation. It furthermore offers dynamic design manipulation.

But the thing to consider while buying sketch is, it only supports macOS.

 jQuery

An open-source JavaScript library that simplifies the interactions between an HTML/CSS document. it also offers the developer to concentrate on the functionality of the different domains of front-end development.

PHP

PHP is the most popular back-end language for the web, it has a low learning curve and offers a massive codebase and long history of the open-source developer community. It is widely used in the Web development industry due to its speed, stability, and cross-platform compatibility. This is unlike JavaScript HTML or suggests that process scripts on the client-side or a Web browser.

SASS

The most reliable, mature, and robust CSS extension language often used to extend the functionality of an existing CSS. It is a scripting language that compiles the CSS codes and helps extend the functionality that a CSS site might not get with other tools.

Javascript

JavaScript makes it possible to build rich UI components such as image sliders, pop-ups, site navigation mega menus, form validations, tabs, accordions. It further helps in isolating code to the specific browser.

Sublime-Text

A well-designed code editor, which provides a super speedy and super-efficient interface. The keyboard shortcut is what makes it a unique tool, it’s the ability to perform the editing simultaneously while navigating to different files, symbols, and lines.

Github

A tool that helps an individual share code with friends, co-workers, and others. GitHub comes with tools every developer needs to manage one project. It is for both community projects as well as public projects.

Lighthouse

A tool used for improving the quality of a site. It works by providing  recommendations  to improve the page performance,  page loading performance and reduce the render-blocking script. The Lighthouse helps in avoiding page redirects and also displays the unused Javascript on the page.

 APIs

APIs dictates how most server-side software architectures are built. Postman  features faster development, faster bug fixes, and around 8x more effective team collaboration than any other API platform. HoppScotch is a popular API development tool that functions both beautifully and smoothly. It offers a gorgeous design with advanced functionality.

Ruby On Rails

Developed back in the mid-1990s Japan,  often regarded it as the safe, elegant, and powerful language, it was designed with keeping humans in mind and their productivity level, which is why it is preferred. Ruby also takes object-oriented programming (OOP) to the next level, through its use of blocks or first-class objects. Ruby on Rails is the best ruby framework, with a library called “gems” it gets distributed through Ruby manager.

The last but not least Adobe XD

If sketching framework is your forte, then look no more, make the move, and add Adobe XD to your arsenal.
