Exploring the Remarkable Benefits of Docker Containers

Shantun Parmar — Fri, 07 Jul 2023 13:45:27 +0000

In recent years, Docker containers have revolutionized the way software applications are developed, deployed, and managed. Docker, an open-source containerization platform, has gained popularity among developers, DevOps teams, and system administrators due to its many benefits. In this article, we’ll take a look at the benefits of docker containers offer and understand why they’ve become an indispensable tool in modern software development.

Lightweight and efficient
One of the benefits of docker containers is their lightness. Unlike traditional virtual machines (VMs), which require a full operating system to run each instance, Docker containers take advantage of the host operating system and share its kernel. This eliminates the need for a separate operating system for each container, resulting in significantly reduced resource consumption and faster boot times. The lightweight nature of Docker containers allows for efficient use of hardware resources, resulting in greater scalability and cost savings.

Portability and Consistency
Docker containers encapsulate all the dependencies and libraries required for an application, ensuring consistency and reproducibility across all environments. Once a container is created, it can be easily deployed and run on any host machine, regardless of the underlying infrastructure. This portability eliminates the “it works on my computer” problem and streamlines the software deployment process. Developers can securely bundle their applications with all required components, ensuring they run consistently across development, test, and production environments.

Isolation and security
Docker containers provide strong isolation between applications and their underlying host system. Each container operates in its own isolated environment, ensuring that problems or vulnerabilities in one container do not affect others. This isolation improves security by preventing unauthorized access to critical resources and reducing the potential attack surface. Additionally, Docker allows granular control over container permissions and resource allocation, allowing administrators to implement strong security measures.

Scalability and Elasticity
The scalability capabilities of Docker are exceptional. Containers can easily scale up or down as needed, allowing applications to efficiently handle varying workloads. With Docker orchestration tools like Docker Swarm or Kubernetes, developers can easily manage and scale large amounts of containers. The ability to scale quickly and automatically enables organizations to respond to changes in user demand, which improves application performance and user experience.

Fast Application Delivery
Docker simplifies the application deployment process, enabling faster and more frequent releases. By packaging applications in self-contained containers, developers can avoid conflicts with the underlying system and reduce deployment errors. Containers can be built and deployed in seconds, streamlining continuous integration and continuous deployment (CI/CD) pipelines. Docker’s infrastructure-as-code approach makes it easy to release, manage, and roll back deployments, which speeds time to market for software products.

Easy Development Environment Setup
Developers often face challenges when setting up their development environments, especially when working on projects with multiple Dependencies. Docker containers solve this problem by providing a consistent and repeatable development environment across all machines. Developers can define a Dockerfile containing all necessary configurations and dependencies and launch identical development environments with it. This consistency eliminates compatibility issues, reduces setup time, and ensures that all developers are working in the same environment.

Conclusion
Docker containers have changed the way software applications are developed, deployed, and managed. Due to their lightweight and efficient nature, portability, isolation, and scalability, Docker containers offer many benefits to developers, operations teams, and businesses. The ability to bundle applications and their dependencies into self-contained units provides consistency, simplifies deployment, and improves security. As technology advances, Docker containers will undoubtedly play a vital role in shaping the future of software development and deployment practices.

Artificial intelligence is the power behind numerous advanced innovative solaces that are currently essential for our everyday lives, from an assortment of brilliant contraptions to Netflix proposals to items like Amazon's Alexa and Google Home.

In 2019, the worldwide AI market size was assessed at $39.9 billion and an accumulate yearly development rate (CAGR) of up to 42.2 percent is relied upon from 2020 to 2027. With consistent study, innovation has made huge improvements in significant fields like medical care, retail, auto, assembling, and money. Computer based intelligence is one fundamental part that vows to totally change the computerized age with high exactness and precision.

1. Robotic Process Automation (RPA)

To smooth out business measures and decrease costs, more CIOs are going to a developing innovation practice called Robotic Process Automation (RPA). With RPA, organizations can automate rule-based drawn-out business measures, permitting their labor force to give more opportunity to serving customers or other higher-esteem work.

RPA is focused on the automation of business measures, represented by business rationale and coordinated information sources. RPA arrangements can go from something as simple as delivering a robotized email reaction to conveying a huge number of bots, each modified in an ERP framework to computerize rule-based errands. RPA is being carried out across industry verticals like assembling, KPO, HR, and finance.

2. Conversational AI

Computer based intelligence fueled chatbots, otherwise called Conversational AI, improve the client experience's reach, responsiveness, and personalization. As per Forrester, conversational AI arrangements change into better automation of client support.

To all the more likely comprehend what the human says and needs, an AI-controlled chatbot utilizes normal language handling (NLP) and AI to give a more regular, close human-level collaboration.

3. Increase in demand for ethical AI

There is a growing interest for ethical AI and it is at the first spot on the list of arising improvements in innovation. The next decade, as per Forrester, will expect CIOs to both react to advanced speed increase and proactively handle vulnerability and business coherence with the moral utilization of Artificial Intelligence.

Seeing how trends are quickly evolving, values-based clients and laborers anticipate that businesses should carry out AI responsibly. Organizations will effectively decide to work with accomplices focused on information morals in the following not many years.

4. AI for Cybersecurity and knowledge breach

In the coming years, information will grow to be extra available, and computerized information will be at more serious danger of being undermined and presented to hacking and phishing assaults. Computer based intelligence and arising innovation will furnish the security office with help in each space against malignant exercises. Artificial intelligence will help deflect cybercrimes later on with improved network protection measures. Counterfeit computerized movement or exchanges that match criminal patterns will be identified by the AI-empowered system.

5. Reinforcement Learning

Reinforced learning (RL) is a particular use of deep learning that works dependent on its experience to upgrade the productivity and viability of information. Some utilization instances of RL are advanced mechanics in arranging business procedures, upgrading promotion content, computerizing enterprises, controlling airplane, and making movement control robots.

6. Quantum AI

To quantify the Qubits for use in supercomputers, progressed organizations will start utilizing quantum incomparability.

How to Create Bitcoin Blockchain Wallets using javascript?

Shantun Parmar — Tue, 22 Jun 2021 16:22:18 +0000

Introduction :

The Bitcoin blockchain is one of the biggest and most impressive blockchains on the planet. It was planned principally to send Bitcoin, the cryptographic money. In this way, normally, to make a message in the Bitcoin blockchain, you should send some Bitcoins starting with one record then onto the next.

A Bitcoin wallet address is made out of 32 unique characters. It permits you to send and get Bitcoins. Your private key is a mysterious code related with your Bitcoin address that allows you to demonstrate your responsibility for Bitcoins connected with the location.

Let's start

What will be covered in this Blog

1.Generate Address Endpoint

2.Validate address

3.Address Balance Endpoint

First of all you will need API for which you can create developer account on platform like block.io or blockcypher.com , Here i am using blockcypher API. Here you can use TESTNET (Testing) and MAINNET (Deployment).

Different Bitcoin addresses:

1.P2PKH which begins with the number 1,
for e.g.: 1PkCrXg22onNePtQmiepDspLJUv7CtkACx

2.P2SH type starting with the number 3,
for e.g.: 3PZjS8D9bA15km6vfHskNnPvHDL73QH2MN

3.Bech32 type starting with bc1, for e.g.:
bc1qGh7s6BYhqV1R3N1qdK8P1KNJjbqmRBs

1. Generate Address Endpoint

API Endpoints

MAINNET

https://api.blockcypher.com/v1/btc/main/addrs

TESTNET

https://api.blockcypher.com/v1/btc/test3/addrs

Make HTTP request

var xhr = new XMLHttpRequest();
xhr.open("POST", url);

xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
   if (xhr.readyState === 4) {

      var data = JSON.parse(xhr.responseText);

   }};

xhr.send();

OUTPUT :

{
"private": "81ee75559d37cbe4b7cbbfb9931ab1ba32172c5cdfc3ac2d020259b4c1104198",
"public": "0231ff9ec76820cb36b69061f6ffb125db3793b4aced468a1261b0680e1ef4883a",
"address": "mvpW7fMSi1nbZhJJDySNS2PUau8ppnu4kY",
"wif": "cRwGhRjCuuNtPgLcoYd1CuAqjFXCV5YNCQ1LB8RsFCvu61VfSsgR"
}

See demo here , Check MAINNET and TESTNET address

2.Validate address

A valid Bitcoin address resembles a ledger number utilizing which you store your bitcoins and check your balances. If you got wrong address then you might lose your money. So before assiging any address make sure it is valid or not.

To validate address we will use a library named as wallet-address-validator.

Installation

NPM

npm install wallet-address-validator

Browser

<script src="wallet-address-validator.min.js"></script>

You may get js from here

Call below function to check validation

    var address = document.getElementById('addr').value;

    var valid = WAValidator.validate(address, 'bitcoin');
    if(valid)
        alert('This is a valid address');
    else
        alert('Address INVALID');

*Note *: This validation will allow you to validate MAINNET

3. Address Balance Endpoint

API Endpoints

TESTNET

https://api.blockcypher.com/v1/btc/test3/addrs/{address}/balance

MAINNET

https://api.blockcypher.com/v1/btc/test3/addrs/{address}/balance

OUTPUT

{
  "address": "mx52XPqpzygzadkk8n1rCZPrC7B4h4UcwT",
  "total_received": 2404904,
  "total_sent": 0,
  "balance": 2404904,
  "unconfirmed_balance": 0,
  "final_balance": 2404904,
  "n_tx": 4,
  "unconfirmed_n_tx": 0,
  "final_n_tx": 4
}

Small play tool for kids in javascript

Shantun Parmar — Sun, 20 Jun 2021 05:31:53 +0000

Children's creativity has been affected the most at this covid time. So for a kids curiosity, I did a little too prep, which is a way to create a drawing by filling colors in a table box.

Introduction

This is the article of the Building an play tool for kids using html and javascript. Where dynamically generated a HTML table with its properties derived from user input. There are 2 main categories of user inputs. The 1st category relates to the overall properties of the table, like the no. of cols, rows, etc, and the 2nd category relates to the properties of each cell in the table.

So let's start,

Here firstly I'll use sublime edito to run the code.

First Simple create an index.html file looks in which you have to create form as depict below image

Here no. of cols and rows will decide table size , Simple cell data mean text which you want to show inside cell as well as you can adjust css using cell width and height.
Colors will draw cell as per selected color, Apart from it if you want to disable editing then set an counter once counter will be finish then table won't be editable anymore.

  <div class="form-group col-md-6">
                    <button class="btn btn-primary" onclick="clock();">Start counter</button>
                    <button class="btn btn-primary" onclick="clearInterval(myTimer);">Stop counter</button>

To run the counter and to stop, two functions have been done to it. Once you selected all element and will click on generate table , generate() function will invoke

function generate() {
    var i;
    var p = document.getElementById("appData");
    var k = document.createElement("hr");
    var e = document.createElement("hr");
    p.appendChild(k);
    var d = document.getElementById("data");
    var n = document.createElement("table");
    var b = document.createElement("body");
    i = document.getElementById("cols").value;
    if (isNaN(i) || i < 1 || i > 100) {
        alert("Not valid input for no. of column, Cannot be blank and must be in range 1 - 100");
        return false;
    } else {
    }
    var o;
    o = document.getElementById("rows").value;
    if (isNaN(o) || o < 1 || o > 100) {
        alert("Not valid input for no. of row, Cannot be blank and must be in range 1 - 100");
        return false;
    } else {
    }
    var m = document.getElementById("height").value;
    if (isNaN(m) || m < 1 || m > 50) {
        alert("Not valid input for no. of height, Cannot be blank and must be in range 1 - 50");
        return false;
    } else {
    }
    var a = document.getElementById("width").value;
    if (isNaN(a) || a < 1 || a > 50) {
        alert("Not valid input for no. of width, Cannot be blank and must be in range 1 - 50");
        return false;
    } else {
        alert("Input OK");
    }
    for (var h = 0; h < o; h++) {
        var g = document.createElement("TR");
        b.appendChild(g);
        for (var j = 0; j < i; j++) {
            var c = document.createElement("TD");
            c.width = document.getElementById("width").value;
            c.height = document.getElementById("height").value;
            var l = d.value;
            var f = "cell [" + j + ", " + h + "]";
            c.setAttribute("id", f.toString());
            c.addEventListener("click", function () {
                cellClicked(this);
            });
            c.addEventListener("mouseover", function () {
                mouseHover(this);
            });
            if (l) {
                c.appendChild(document.createTextNode(l));
            } else {
                c.appendChild(document.createTextNode("Cell" + j + "," + h));
            }
            g.appendChild(c);
        }
    }
    n.appendChild(b);
    p.appendChild(n);
    p.appendChild(e);
}

This snippet create dynamic table. Once it will done then move your cursor and select various colors. Your table will look a like below image

Don't want miss recent post on dev, Make feed on your web

Shantun Parmar — Thu, 29 Apr 2021 05:33:40 +0000

Dev is a community of software/web developers getting together to assist each other. We can’t be active all time over community so don’t miss creative post, You can get all post under single page over your website or your blog.

Let’s start with node.js

I will show you to scrap dev.to latest post including their title and relevant content. You will be required to include Axios npm package to send http request over dev.to. This package will extract html of latest post, Afterward you need to load html and have to scrap html content, For which you must install cheerio npm package.

Http request to extract html using axios

axios.get(url)
.then(response => {
getData(response.data);
})
.catch(error=>{
console.log(error);
})

Load and scrap html using cheerio

let getData = html => {
  data = [];
  const $ = cheerio.load(html);
  $('a.crayons-story__hidden-navigation-link').each((i, elem) => {
    data.push({
      title : $(elem).text(),
      link:$(elem).attr('href')
    });

  });

Here i just scrap title and their href , Whatever you want to scrap of a post , you may access using class name or id. Store scrap data into an array and send to view files for render.

<div class="jumbotron">
        <h1>Dev.to Feeds</h1>
        <ul>
        <% data.forEach(function(elem) { %>
            <li>
                <strong><a href="https://dev.to/<%= elem.link %>"><%= elem.title %></a></strong>

            </li>
        <% }); %>
    </ul>
    </div>
