What is GitOps?

2023-06-13T10:24:00.005+05:30

Learn how GitOps manages infrastructure through code and automation by building on the success of DevOps practices.

The DevOps playbook has proven its value for many organizations by improving software development agility, efficiency, and speed.

DevOps enables developers to rapidly and frequently release new features and services by using continuous integration and continuous delivery (CI/CD), suites of collaboration tools, and version control practices, most often with the open source Git software at its core.

These methods improve the software development lifecycle (SDLC), but what if infrastructure deployment and management could also benefit? This method known as GitOps would also boost the speed and efficiency of practicing DevOps organizations.

What is GitOps?

GitOps is a specialized, prescriptive discipline of DevOps used to achieve similar goals of speed and efficiency. Building on the success of DevOps practices, GitOps is a relatively new way to manage infrastructure through code and automation, around a single Git repository (or a storage system for all the changes and files that relate to a given project).

Development teams use GitOps to specify their infrastructure requirements in code. Known as infrastructure as code (IaC), it can build out infrastructure automatically to scale. GitOps improves speed and scalability. Instead of manually setting up each configuration, the same environmental configuration is deployed and synced for each application deployment.

These practices can be a boon to infrastructure management, but GitOps presents challenges. The major challenge is ensuring that all participants are committed and accountable to the process while consistently documenting changes to production environments. GitOps also requires extensive approvals for any development.

Another challenge is the lack of expertise and lack of guidance. While GitOps can work without cloud, having Kubernetes knowledge helps to fully understand the function and impact of GitOps processes (teams can use GitOps outside of Kubernetes, but the practice is more commonly used with Kubernetes). Managing clusters through Git requires a broad and deep knowledge of Kubernetes to get the most from GitOps’ version control and verification advantages.

How does GitOps work?

At its most basic, GitOps uses Git repositories to store configuration files that define the desired state of your infrastructure, such as a Kubernetes cluster or any cloud-native application. Much like in software development, push-pull requests make changes to the files and merge them with the main file. Then, automation tools check the operation of those changes before deploying them to the Kubernetes cluster.

A key function of GitOps practices is verification. Since we can observe the state of the environment and view the specific Git repository, we can verify that the environment is in the new, desired state. The fluidity of this process is possible through automation tools compatible with Kubernetes.

What is a GitOps workflow?

In an example scenario, a team decides they need to change the Git repo to support the deployment of a new service. First, a developer creates a branch from the trunk, or main branch, of a Git repository. The developer then modifies the configuration files to include specifications for the new namespace and set of nodes into a configuration template. Then, a developer creates a pull request in Git. Another developer on the team can review the pull request before merging into the main branch. After merging, a CI/CD pipeline builds, tests, and deploys the application. Then a GitOps operator deploys the new configuration template. Kubernetes ends the workflow using a convergence mechanism that can detect differences in the current and desired configuration states. The mechanism eventually syncs the two with the new configuration changes applied. This new configuration state, as a template, can then be applied to hundreds of different application environments. It is scalable and reduces time needed to set up infrastructure.

Kubernetes, CI/CD, and GitOps

GitOps, when practiced successfully, empowers managing your Kubernetes clusters. Containers have become the standard way to deploy cloud-native services, and Kubernetes is the most widely-used container orchestration system. Managing Kubernetes can be challenging, especially if you depend on ad hoc scripts to make calls to the Kubernetes application programming interface and make changes to a cluster. If you’re new to Kubernetes, download the ebook The State of the Kubernetes Ecosystem to see how it can work across a host of environments.

While Kubernetes is a powerful platform, it depends on complex automation tasks that can make troubleshooting challenging. Developers can easily make a series of changes to a Kubernetes cluster using imperative kubectl commands that leave the cluster in an unexpected, unwanted state. Finding the source of the unwanted behavior or cluster states takes time that eats into other pressing infrastructure work.

Using declarative specifications and CI/CD pipelines helps avoid these kinds of problems. If there is a specification error, developers can use the same CI/CD pipelines to return to a previous working state.

Continuous integration processes prevent conflicting merges by utilizing automated management systems to properly organize and merge code. For GitOps, this means that changes to Kubernetes deployments won’t conflict. Conflicts would cause disruptions and require tedious troubleshooting sessions. Continuous delivery processes similarly streamline operations by breaking deployment changes into smaller chunks. This makes tracking and managing Kubernetes infrastructure more manageable and reduces deployment errors. Because the pipeline promotes controlled integration and delivery, rolling back infrastructure to a working state is faster and more efficient.

Using CI/CD with infrastructure unlocks the benefits of a modern software delivery life cycle. GitOps shores up infrastructure stability, and CI/CD pipelines are a crucial part of that function. With GitOps taking advantage of DevOps’ success, the result is greater automation and stability.

Dynatrace enables observability in GitOps

As more teams apply GitOps as an operational framework to automate the provisioning of infrastructure, Dynatrace’s monitoring platform facilitates observability through integrations with monitoring and configuration tools such as Prometheus, Jaeger, Ansible, and cloud-specific integrations. Dynatrace also supports monitoring as code and GitOps practices through Monaco. This supports automated syncing of environment configurations that can be scaled to all your applications to reduce onboarding time. GitOps practices can improve infrastructure management efficiency and stability. But without proper monitoring tools, it’s easy to get bogged down with the intricacies of Kubernetes deployments. With Dynatrace, you will gain deeper insights into the state of your infrastructure with end-to-end observability, distributed tracing, and cloud automation.

Basic Concepts of Object-Oriented Programming

2022-02-10T11:33:00.000+05:30

Introduction

OOPs, or Object-Oriented Programming is a programming model or paradigm which revolves around the concept of “OBJECTS”. Objects can be considered as real-world instances of entities like class, that contain some characteristics and behaviors specified in the class template.

What Is Object-Oriented Programming?

Object-Oriented Programming(OOP), is all about creating “objects”. An object is a group of interrelated variables and functions. These variables are often referred to as properties of the object and functions are referred to as the behavior of the objects. These objects provide a better and clear structure for the program.

For example, a car can be an object. If we consider the car as an object then its properties would be – its color, its model, its price, its brand, etc. And its behavior/function would be acceleration, slowing down, gear change.

Another example- If we consider a dog as an object then its properties would be- his color, his breed, his name, his weight, etc. And his behavior/function would be walking, barking, playing, etc.

What Is The Need For OOPs?

There are many reasons why OOPs is mostly preferred, but the most important among them are:

OOPs helps users to understand the software easily, although they don’t know the actual implementation.
With OOPs, the readability, understandability, and maintainability of the code increase multifold.
Even very big software can be easily written and managed easily using OOPs.

What Are Some Major Object Oriented Programming Languages?

The programming languages that use and follow the Object-Oriented Programming paradigm or OOPs, are known as Object-Oriented Programming languages. Some of the major Object-Oriented Programming languages include:

Java
C++
Javascript
Python
PHP

And many more.

What Are The Main Features Of OOPs?

OOPs or Object Oriented Programming mainly comprises of the below four features, and make sure you don't miss any of these:

Inheritance
Encapsulation
Polymorphism
Data Abstraction

Why Is OOPs So Popular?

OOPs programming paradigm is considered as a better style of programming. Not only it helps in writing a complex piece of code easily, but it also allows users to handle and maintain them easily as well. Not only that, the main pillar of OOPs - Data Abstraction, Encapsulation, Inheritance, and Polymorphism, makes it easy for programmers to solve complex scenarios. As a result of these, OOPs is so popular.

The term “software” first appeared in print in the 1960s has since become ingrained in our society as a staple product across a variety of industries. The industry rapidly expanded in the ’70s and has since become one of the biggest industries in the world.

Today, software is found on almost anything that uses electricity, either embedded into a gadget or installed via a program on a mobile device or computer.

The software industry is divided into four main categories including system services, programming services, open-source, and software as a service (SaaS). The programming services sector has traditionally been the largest sector including pioneers like Microsoft Corporation, Automatic Data Processing (ADP), Oracle Corporation, and SDC Technologies.

Today’s software companies have the ability to change the world. We interact with intelligent software so often, we probably don’t even realize it. But some of the basic software you see on a daily basis are Microsoft Word, Avira, Adobe Photoshop, Windows Media Player, and more.

Our lives in business are easier with software applications as we often use software applications like managing databases, accounts, billing, payroll, and more. We use software in healthcare, banking, general communication, and more.

Valued at over $533 billion, the software industry is projected to reach a market value of $773 billion by 2025. It’s no surprise at how much software has exploded over the past years, as it plays such a significant role in our everyday lives, both for professional business and personal use.

Everything You Need To Know About PHP - thakurbhaskar

2021-12-24T10:43:00.004+05:30

PHP stands for PHP: Hypertext Preprocessor is a widely used open-source server-side scripting language especially suited for creating dynamic websites and mobile APIs.

PHP supports many databases like MySQL, Solid, PostgreSQL, Oracle, Sybase, generic ODBC, etc. PHP code is embedded within HTML.

It is used to manage dynamic content, session tracking, databases, and also to build an entire e-commerce site.

By default, most of the web hosting servers support PHP and thus it contributes to cost-effectiveness.

Scope of PHP

PHP stands as one of the top languages because of its ability to have a large impact on the outcome with very little code. This amount of efficiency has been the requirement for the past few years in the industry.

On seeing this, companies are investing a good amount of money in hiring proficient PHP developers to fit these shoes and work effectively.

Today, this article will walk you through the most commonly asked PHP interview questions for freshers and experienced in the industry.

What is a session in PHP

A session in PHP is a way to store information to be used across multiple pages of an entire website. The information is not stored on the user’s computer, unlike cookies. In a temporary directory on the server, a file will be created by the session where registered session variables and their values are stored. This information will be available to all pages on the site during that visit.

When you work with an application, you open it, do some modifications, and then you close it. This is much like a Session. The computer knows who you are. It knows when the application is started and ended by you.

But on the internet, the webserver does not know who you are or what you do, because the HTTP address doesn’t maintain a state. This problem is solved using session variables by storing user information to be used across multiple pages (e.g. username, favorite color, etc).

By default, session variables will last until the user closes the browser.

So Session variables hold single user information and are available to all pages in one application.

What are cookies? How to create cookies in PHP?

A cookie is a small record that the server installs on the client’s computer. They store data about a user on the browser. It is used to identify a user and is embedded on the user’s computer when they request a particular page. Each time a similar PC asks for a page with a program, it will send the cookie as well.

After verifying the user’s identity in encrypted form, cookies maintain the session id generated at the back end. It must reside in the browser of the machine. You can store only string values not object because you cannot access any object across the website or web apps.

By default, cookies are URL particular. For example, Gmail cookies are not supported by Yahoo and vice versa. Cookies are temporary and transitory by default. Per site 20 cookies can be created in a single website or web app. 50 bytes is the initial size of the cookie and 4096 bytes is the maximum size of the cookie.

In PHP, we can create cookies using the setcookie() function:

setcookie(name, value, expire, path, domain, secure, httponly);

Here name is mandatory and the remaining parameters are optional.

Example:

setcookie(“instrument_selected”, “guitar”)

Top Notch Frameworks For Desktop Application Development

2021-05-13T13:52:00.011+05:30

As a desktop developer, choosing the best framework to use is never a walk in the park. In addition to analyzing only the features of a particular framework, you need to consider the pros and cons that come with using a particular framework. So, which is the best framework for desktop application development?

In this article, we are going to look at the best frameworks for desktop application development.

Use Case for Desktop Frameworks

Before we list the best frameworks, it is important to ask ourselves this question: What are some of the applications that can be built by these frameworks? To make things easier, here is a list of some of the things that you can build using desktop software development frameworks:

Standalone business application
Client-server application
Collaborative applications
Utilities and plugins
Multimedia applications
Network applications

Top 5 Desktop Application Development Frameworks

Here are the best frameworks for desktop application development

1. WPF

This is one of the most popular frameworks for native Windows application development. Windows Presentation Foundation (WPF) is a framework within the .NET framework that is mainly used for developing the graphics of a desktop application. You will use it to create the user interface for software.

WPF has been part if the .NET family since 2006 and has managed to win the hearts of many programmers. The runtime libraries of the WPF are usually embedded in the Windows operating system. A key characteristic of WPF is its ability to unify different user interface elements. These elements include vector graphics, adaptive documents, pre-rendered media objects and rendering 2D and 3D.

2. Universal Windows Platform (UWP)

UWP is another important framework for desktop application development. It is also a framework that is highly credited for the popularity of the .NET platform. This is because it allows developers to create cross-platform desktop applications.

Basically, UWP allows developers to create applications that can run on many different Microsoft-owned platforms. This means that your software will be able to run on multiple devices. This is made possible by a special algorithm for Windows application development.

UWP framework is highly scalable. If you had built an application for desktop, the framework will make it possible to scale it for mobile devices. The app will be able to run smoothly on mobile, tablet and even on Xbox. It is a framework that has greatly improve the functionality of Visual Studio.

3. Cocoa

Cocoa is a native framework for native MacOs development. It is an object-oriented framework for building a user interface for the MacOS, iOS, and tvOS. It not only adds the functionality of the UI but also makes the interface more entertaining.

With Cocoa framework, you can add the animation feature, graphic control element and gesture recognition features into a desktop application. All the development tools for Cocoa are provided by Apple. When it comes to writing codes, the framework can be used with Python, Perl, and Ruby languages. To use these languages, you will need bridges such as PyObjC, PasCocoa, and RubyCocoa. The cocoa framework will help you to stick to the strict guidelines of Apple.

4. Electron Js

Electron is a cross-platform development framework that was developed by GitHub. The framework uses Node.js and developers can use it to build cross-platform desktop applications. From the look of things, there is quite a number of big companies that are using this platform to develop their applications. They include Facebook, Microsoft, and Stack.

As a web developer, you can use Electron to build a desktop application. The framework allows developers to focus on the core functionalities of the software. This is because the framework handles the hardest parts of a software development process.

5. Swing

Swing is a Java-based framework that you can use to develop a desktop application. Being a cross-platform framework, the applications build by Swing can run on any platform.

The main function of Swing is to build a better GUI for desktop applications. It is able to emulate the design, look, and style of many desktop applications. The framework comes with various UI components such as buttons, panels, tables scroll panes and checkboxes.

As you can see, some frameworks are for native Windows, others are MacOs while others are cross-platform development frameworks. The nature of the desktop application that you are developing will determine the development framework to use.

Battlegrounds Mobile India Is Back: Know More

2021-05-08T19:49:00.001+05:30

Key Points:

· · Sanskari Type of Structure of the game

· · Restrictions for 18 Below Gamers

· · User data will be stored in India

Due to national security issues, PUBG Mobile was banned in India last September. Nevertheless, PUBG Mobile was showcased as Battleground Mobile India in the Indian market yesterday. The game's developer Krafton says that Battleground Mobile India is valid in accordance with all government laws in the country. Although the date of the battle is not yet released for Mobile India, Krafton announced on its official website to provide detailed information about the game, including players under the age of 18. Here is what you need to know about the game when you are excited. Also about the launch of Battleground Mobile India.

Krafton has not confirmed the launch date (ie, when it is available for download) for Battleground Mobile India. However, the developer has announced that Battleground Mobile India will be pre-registered before the game is released in the country. This is why Battleground Mobile India is likely to launch the game in the next few weeks as the official website has now gone live for the game.

Krafton revealed that Battleground Mobile India is launching as a "free" game app in the country. This means that you will not have to pay for the game. Although no specific information has been provided, Battleground Mobile India will be released and downloaded from the Google Play Store or Apple App Store, Android and iOS platforms.

More features of Battleground Mobile India

Krafton announced in a press release that the Mobile India Battleground has Indian-specific features. The game maker says that the game will be made special to the citizens of the country with sporting events, costumes, competitions and leagues. Earlier reports state that Mobile India Battleground will have an avatar opposite PUBG, where you are half-naked in the video. It seems that the developer will decide whether Battlefields Mobile India will be better for the people or more rewarding.

Another change in Battleground Mobile India as compared to PUBG Mobile is that according to online sources, there can be no bloodshed. At least, when you kill someone, red blood will not be in the game. Rather, when you are killing a keel, you will see green material. Violence / bloodshed should not be seen among Indian youth under 18, PUBG Mobile has become famous. Since PUBG Mobile had many violent scenes, Indian parents were particularly concerned.

Gamemaking company Battleground Mobile India has an AAA multiplayer mobile game experience. While no specific information is available on this front, everyone hopes that Battleground Mobile India will be a royal battle game.

As the name suggests, Mobile India Battlegrounds for the Indian market will not be released in any other region. It says that you cannot play Mobile India Battleground with people abroad. One of the outstanding features of PUBG Mobile in China is the chance to play a game with the people of the country, available worldwide. Unfortunately, with the upcoming title, this will not be the case.

Restrictions for 18 Below Gamers

Battlegrounds Mobile India’s official website presents the game’s privacy policy. There are also limits on players under 18 years of age under the Data Protection Rules. Battlegrounds Mobile India requires parental permission for minors to play the game, as stated in their privacy policy. The platform indicates that the mobile number of parents or guardians must be entered in the game to confirm parental consent by people under 18.

In addition, Mobile India Battlegrounds would not allow minors to play for more than three hours a day. For the people who love to do long games, this might be a big bummer. Also, Not more than Rs 7,000 for in-app transactions in Battlefield Mobile India will be enabled for people under 18 years.

Google Assistant can add voice shortcuts that don't require "Hey Google" to activate

2021-04-25T07:46:00.004+05:30

Google Assistant has become one of the best devices of our lives, as it allows us to interact with our smartphones while we are not touching them. But if I want to use it that way, I have to say "Hey Google" to Google Assistant to start listening to me. And, I have to bring it myself. "Hey Google" is the keyword the assistant uses to find out if someone is talking. Sometimes, though, "Hey Google" is too many words for things like snatching your alarm, so Google may soon add "voice shortcuts" for Google Assistant, which is apparently internally called Guacamole.

Voice shortcuts are a very short command that will allow you to say "OK Google" for tasks such as stopping an alarm or answering a call. Right now, the feature is not live, but we managed to show it in the settings of the Google app, as did AndroidPolice and 9to5Google. Not that we were able to do anything with the feature's toggle, though, and neither of the other two sites could, because it doesn't work yet: the app tells you that by actually turning First you should read some terms and conditions. Feature on, but the link to those terms and conditions is broken, and the toggle does nothing when you turn it on.

Ultimately, however, Google may plan to introduce this feature to Google Assistant during Google I / O 2021, which will be inspired by the free-for-all and free-running COVID-19 epidemic this year. Therefore, this apparently incomplete facility cannot be made available by accident. We will probably learn more about this feature soon. Before it expires, Google can add or remove functionality or end up altogether - we don't really know at this stage.

Microsoft is rolling out the new Edge Canary

2021-04-16T15:41:00.001+05:30

After announcing plans to integrate the Edge codebase into multiple platforms last month, Microsoft has now released a new Edge Canary build for Android users. The new build (v91.0.858.0) matches the Edge Canary release for the desktop and brings a new UI, features, menu layout and more.

The new Microsoft Edge Canary app for Android was first spotted by Reddit user u/howdoiuseredditlol (via Windows Central). The app offers a different set of features than the current Edge Beta build (v46.03.23.5155) on Android, including advanced features such as a reading mode and full access to experimental flags.

You can download the new Edge Canary release by following the Play Store link below and go to the edge to try out a host of experimental features: // Flag Note that after this is a Canary release, you can find bugs and Others may face stability issues. Thankfully, you can have both the Canary and Stable versions of Edge installed simultaneously on your device, so if this happens you can quickly revert to a stable release.

Sadly, the Play Store listing does not include a changelog for the new Edge Canary build for Android. It states: “Microsoft Edge preview channels are now available for mobile! This is the Microsoft Edge Canary channel for Android. The Canary will be released daily to keep you updated on our progress. Your feedback is what helps us improve, so download now and let us know what you think. "Therefore, we expect Microsoft to roll out more features and changes for the release with each daily update.

The new Microsoft Edge Canary release for Android comes one day after the company introduced a new Kids Mode on the desktop version of the browser. Kids Mode is designed to help parents provide a safe browsing experience for young users by whitelisting a small selection of websites. The mode includes two options - one for users aged 5–8 years that provides a simplified browsing experience and another for users aged 9–12 years who like child-friendly articles and animals, science, etc. Provides news on topics.

OnePlus Watch cloned Wear OS but made it so much worse

2021-04-15T04:47:00.008+05:30

After years of its loyal community for smartwatches, OnePlus has finally delivered with its $ 159 OnePlus Watch. We have a full review of the new product in the works, but the many days I've spent so far with the OnePlus Watch have been a major deadlock in the software; that is not good.

OnePlus Watch software is a glaring Wear OS clone

They say that imitation is the most honest form of flattery, and from its look, OnePlus really likes what Google has done with Wear OS.

The software that ships on the OnePlus Watch is about as close as you can get to a 1-to-1 clone of Google’s platform. That starts with the navigation. From the watchface, a swipe down reveals the quick settings menu, looking nearly identical to its Wear OS counterpart, albeit with some different functions. A swipe from the watchface shows your notifications, which again, look similar to how they do on Google's platform. To the right of the watchface, you have "cards" for options like workouts, weather, music, and more.

The similarities continue from there. When switching watchfaces or adding "cards", the design is similar to the same function on Wear OS. The app drawer also looks similar and rotates in the same way. The only thing OnePlus doesn't have is the leftmost screen, a Google Assistant page on Wear OS.

This is remarkably unfinished and unpolished

OnePlus makes its software a matter of pride, which is why I was just shocked at the major flaws with the Watch. Here are some examples so far.

The first defect appears during setup. Pairing is remarkably quick, but the OnePlus health app is a mess. During setup, you are asked to insert in your gender and birthday, but icons for gender are unnecessarily confusing. However compared to the rest it is modest. I had to install a system update on my watch after unboxing it, and during that process, the watch switched from English to Chinese. It was confusing!

What if parent pointers are not available?

2021-04-12T12:47:00.003+05:30

If parent pointers are not available, the BSTs can be converted to linked list and then merged.

1. Convert both the BSTs into sorted doubly linked list in O(n + m) time. This produces 2 sorted lists.

2. Merge the two double linked list into one and also maintain the count of the total elements in O(n + m) time.

3. Convert the sorted doubly linked list into height balanced tree in O(n + m) time.

What Is Natural Language Processing?

2021-04-12T08:31:00.003+05:30

Natural Language Processing (NLP) is a subfield of computer science that is focused on allowing computers to understand language in a “natural” way, as humans do.

NLP has become a rapidly evolving field, and one whose applications have represented a large portion of artificial intelligence (AI). Some examples of that implemented by using deep learning are chatbots that handle customer service requests, auto-spellcheck on cell phones, and AI assistants, such as Cortana and Siri, on smartphones.

The History of Natural Language Processing

Natural Language Processing can be classified as a subset of the broader field of speech and language processing. Because of this, NLP shares similarities such as computational linguistics, which is concerned with modeling language using rule-based models. NLP’s inception can be traced back to the development of computer science in the 1940s. For examples, the alphabet is the simplest structure, in that it is a collection of letters that can form strings called words. A formal language is one that has a regular, context-free, and formal grammar. In addition to the development of computer sciences as a whole, artificial intelligence’s advancements also played a role in our continuing understanding of NLP.

Amazon Android app just got redesigned with new updates

2021-04-03T16:44:00.000+05:30

If you regularly use the Amazon Android app, you’ve probably noticed that it’s… not great. People have long complained about the app’s design, but thankfully important changes have been introduced that improve the overall experience.

Amazon has apparently released an update to its Android app (via Droid-Life) that introduces a bottom navigation bar. The bar includes quick links to home, your profile, shopping cart, and a menu for your orders, lists, account information, and more. The update more closely matches what’s already available on iOS.

Droid-Life also points out that the Amazon Android app also includes a font change — or a change to the font size — which you can see in various parts of the app. Overall, the app looks a lot cleaner and arrives after Amazon changed the Android app’s icon.

The update should be live for all at the link below.

What is Program Development Cycle?

2021-03-30T14:28:00.004+05:30

Programming is a knowledge-based task; it can be stated art professionally to write a code with minimum memory utilization. It is not just a typing. It involves knowledge and the sequential approach of development. Let us understand the program development life cycle.

We need to consider the following steps:

1. Understand the Problem Statement

Programmers have to know about the user’s requirements before typing anything because a program or software is going to be used by that user or users.

First, we need to think about what kind of output has to produce. Then we can plan for what kind of inputs will be required to generate the output. Some documentation can help in this, such as original requests for the program from users, sample output, and descriptions of the data items available for input. Still the Understanding the problem is a challenging task.

2. Prepare the Logic

Preparing the logic is the prime activity of the program development cycle. Its prerequisite is to have analytical skills. Whatever information is gathered from the user, we need to analyze it and prepare a scenario. Here we have to start planning the steps for writing the code and finalize the sequence of the steps. For this, we can use flowcharts or pseudocode. Planning a program is also referred to as “developing an algorithm’ An algorithm is the sequence of steps or rules we follow to solve a problem.

In this step, the programmer needs to think carefully about all the possible data values a Program might encounter and how we want the program to handle each scenario.

3. Write a Code

In this step, first, we need to decide which programming language to be used. Despite their differences, programming languages are quite similar in their basic capabilities. After choosing a language, the programmer must be concerned about using the correct syntax.

4. Use Software (a compiler or interpreter)

Programming languages use human-understandable language such as English. After writing code, it needs to be converted in machine language as the computer knows only machine language, which consists of Inputs and Outputs. To achieve this, we use a translator program (a compiler or interpreter) that converts high-level programming language into the low-level machine language that the computer understands.

This software also helps programmers by notifying for incorrect syntax, which is referred to as error messages.

5. Test the Program

Sometimes an error-free program may have logical errors. A logical error results after using a syntactic correct statement; however, use the incorrect one for this context. So the programmer has to execute the program and provide some sample data to see whether the results are logically correct. The process of finding and correcting program errors is called debugging.

6. Put the Program into Production

Putting the program into production is simply executing the program to make sure that it is working as per the requirement. Users also to be trained to understand that how to use the program to generate output.

7. Maintain the Program.

After programs square measure place into production, creating necessary changes is termed maintenance. Changes may occur because of changes in government rule for taxes or maybe as per the user’s requirement.

What are the types of IP Addresses?

2021-03-29T07:36:00.000+05:30

What is IP Address?

A single IP address is a system that recognizes a local network or online device. IP means “Internet Protocol,” the guidelines set for the data format transmitted over the internet or the local network.

IP addresses are basically the identifier that can be transmitted to computers on the network: they provide location data and make devices available for communication. The Internet requires a means of discriminating between machines, routers, and websites. IP addresses are an integral part of the Internet’s way to do so.

The ranges of IP addresses and the various forms are available for each category.

User IP Address:

There will be two kinds of IP addresses for each person or company using an internet service plan: their private IP address and public IP address. The public and private words are for the network venue, which is to say for the use of a private IP address within a network and for the use of a public address outside a network.

IP addresses for private users:

A private IP address is available for each computer connecting to the network. Computers, laptops, tablets, and all accessories such as microphones, printers, or smart TVs may also be used. This includes the increasing internet of things is likely to increase the number of private IP addresses at home. Your router needs to be able to recognize these objects individually and several items need to be recognized. Therefore, for each system that differentiates between them on the network the router creates private IP addresses that are unique.

Public IP Addresses:

The main address for the entire network is a public IP address. Each linked computer has an IP address of its own but is also included in your network’s principal IP address. Your IP address is supplied by your ISP to your public router, as mentioned above. In general, ISPs have a wide variety of IP addresses they offer to their customers. The public IP address that your network recognizes is the address that all users outside your internet network use.

This Public IP comes into two categories: Dynamic IP and Static IP

Dynamic IP Address:

Automatically and periodically, dynamic IP addresses alter. ISP’s order and assign a wide pool of IP addresses to their customers instantly. They regularly reassign them to the pool for use for other customers and restore the older IP addresses. The reason for this strategy is to save the ISP costs. Automating the routine movement of IP addresses ensures that, for example, once you go home, you do not have to take special steps to return the IP address to a client. Protection advantages exist too because it is difficult for hackers to break into the network interface because of a changing IP address.

Static IP Address:

Static addresses remain stable as opposed to dynamic IP addresses. The network will stay the same until the IP address is assigned. Most people and organizations don’t require a static IP address, but one is important for companies who plan to run their own servers. A static IP address means that websites and their related email addresses have a stable IP address — which is important if you want other devices to reach them reliably on the Internet.

This contributes to the next element – the two kinds of IP addresses on the website.

Two forms of IP addresses are available

There are two kinds of website IP addresses for the site owner who does not host their own servers and relies on a web hosting kit instead. These are committed and circulated.

Shared IP Address:

Pages that rely on joint hosting plans from providers of web hosting are usually one of many websites on the same server. This is usually true for individual websites, SME websites, where the amount of traffic and the number of pages, etc. are small. Hosting services will exchange IP addresses in this manner.

Dedicated IP Address:

Any web hosting plan can buy a specific IP address (or addresses). This makes it easy to get an SSL certificate that helps you to run the FTP servers. This simplifies the sharing, file transmission, and anonymous sharing possibilities in FTPs, for many users within an enterprise. You can also access your website by a dedicated IP address alone rather than via a domain name – it’s helpful to create and validate your domain before registering it.

OnePlus 9 series: Everything you need to know about OnePlus’ latest flagships

2021-03-28T07:50:00.003+05:30

OnePlus’ hype train has finally reached its destination, and the company has unveiled its latest flagships — the OnePlus 9, the OnePlus 9 Pro, and the OnePlus 9R. The phones feature an all-new design, top-of-the-line performance chops, and a new camera system developed in collaboration with Hasselblad. On top of that, the OnePlus 9 series offers several additional features that make them a significant upgrade over the OnePlus 8 lineup. In case you’re planning on getting a OnePlus 9 series phone for yourself, here’s everything you need to know to make an informed decision:

OnePlus 9 series: Variants

As seen in various leaks over the last few months, the new OnePlus 9 series includes three devices — the OnePlus 9, the OnePlus 9 Pro, and the OnePlus 9R. While the OnePlus 9 and OnePlus 9 Pro are global devices that will be available in all regions where OnePlus has a presence, the OnePlus 9R is limited to the Indian market.

OnePlus 9 series: Specifications

Design

The OnePlus 9 series follows the same Burdenless Design philosophy as a couple of older OnePlus devices but with a few refinements. The devices look pretty much the same as the OnePlus 8 series, except for the new camera module and the back panel finishes. Both phones have a curved back that merges seamlessly with the slim frame, but the OnePlus 9 features a flat display while the OnePlus 9 Pro packs a curved one. The devices also differ in terms of material choice, with the vanilla OnePlus 9 featuring a fiberglass-reinforced frame (with a glossy metallic finish) and the Pro variant packing an aluminum frame.

As mentioned earlier, the OnePlus 9 and 9 Pro sport a new camera island design. Unlike the OnePlus 8 series devices, the latest OnePlus flagships feature rectangular camera islands in the top left corner of the back panel. On the OnePlus 9, the camera module houses a triple camera setup with a dual-LED flash and Hasselblad branding. On the other hand, the Pro variant packs a quad-camera setup with a dual-LED flash and Hasselblad branding.

Both phones also get new back panel finishes. The OnePlus 9 comes in three colorways inspired by nature — Winter Mist, Arctic Sky, and Astral Black. The Winter Mist variant has a gradient refraction effect that lights up the device in different shades of purple, the Arctic Sky variant has a cool blue finish with a matte glass, and the Astral Black finish has a glossy glass on top of a matte black film that offers a minimal look.

The OnePlus 9 Pro also comes in three nature-inspired color options — Morning Mist, Pine Green, and Stellar Black. The Morning Mist finish, which we saw in various leaks over the last few months, shimmers from silver to black, the Pine Green variant offers a double-layer matte finish that gives the device a softer feel, and the Stellar Black variant has a frosted matte glass that resembles the classic OnePlus Sandstone finish.

The affordable OnePlus 9R features a flat display with a hole-punch cutout in the top left corner, a curved glass back, and the same camera island design as the other two models. However, it doesn’t feature Hasselblad branding. It comes in two color variants — Lake Blue and Carbon Black — and both variants have a matte finish. Surprisingly, the OnePlus 9R has a metal frame, while the more premium OnePlus 9 doesn’t.

As far as the ports and buttons are concerned, the OnePlus 9 features a USB Type-C port at the bottom, the power button and alert slider on the right edge, and the volume rocker on the left edge. Similarly, the OnePlus 9 Pro packs a USB Type-C port at the bottom, the power button and alert slider on the right edge, and the volume rocker on the left edge. However, the frame on the Pro variant is a bit slimmer (2.2mm) than the one on the non-Pro variant, which gives it a more premium feel in hand. The OnePlus 9R also features the same button and port layout as the other two devices.

For durability, OnePlus is offering Gorilla Glass 5 on the front and back on both devices and an IP68 rating for dust and water resistance. Do note that the IP68 rating is only available on the T-Mobile version of the OnePlus 9, but it’s available on all variants of the OnePlus 9 Pro. Sadly, the affordable OnePlus 9R doesn’t come with an IP certification.

Display

OnePlus 9

The OnePlus 9 packs a 6.55-inch flat AMOLED display with a resolution of 2400 x 1080 pixels. It’s a 20:9 panel that offers a pixel density of 402 pixels per inch (PPI). The display has a single hole-punch cut-out for the selfie camera in the top-left corner, minimal bezels on three sides, and a slight chin.

The display offers a peak refresh rate of 120Hz, 1100nits of peak brightness with 8192 levels of adjustment, and HDR10+ certification. OnePlus claims that the display supports both sRGB and DCI-P3 color space, and it offers color accuracy that exceeds leading professional monitors. The display also comes with HDR10+ certification.

OnePlus 9 Pro

While the OnePlus 9’s display is pretty much the same as the one on the OnePlus 8T, the OnePlus 9 Pro’s display boasts of a couple of additional features. The curved panel measures 6.7-inches and offers a resolution of 3216 x 1440 pixels. It has a 20.1:9 aspect ratio and offers a pixel density of 525PPI. Much like the OnePlus 9, the display on the Pro-variant features a single hole-punch cut-out for the selfie camera. But its side bezels are much slimmer as the display curves over the edges. The top and bottom bezels are also comparatively slimmer.

The display offers a peak refresh rate of 120Hz, but unlike the vanilla model, it’s an LTPO panel that brings adaptive refresh rate support to the device. Thanks to this, the device can automatically adapt the refresh rate from 1-120Hz based on the content being viewed. OnePlus claims that this feature helps reduce the power consumption by 50% compared to the vanilla model.

The panel also supports a 360Hz touch polling rate for faster touch response, 1300nits of peak brightness, native 10-bit color depth, and HDR10+ certification. Furthermore, the device comes with a few premium display features like MEMC, automatic color temperature adjustment, front/back ambient light sensing for automatic brightness adjustments, and more. As with the OnePlus 9, OnePlus claims that the display supports both sRGB and DCI-P3 color space, and it offers color accuracy that exceeds leading professional monitors.

OnePlus 9R

Despite its affordable price, the OnePlus 9R also packs a FHD+ AMOLED display that refreshes at 120Hz. While it doesn’t offer adaptive refresh rate support or a high touch polling rate, it’s still a great panel for an affordable flagship.

The display has a resolution of 2400 x 1080 pixels, which results in a pixel density of 402 pixels per inch. It has a 20:9 aspect ratio, and it also offers support for the sRGB and DCI-P3 color space.

SoC, RAM, & Storage

As expected, both the OnePlus 9 series devices are powered by Qualcomm’s flagship Snapdragon 888 SoC. The octa-core SoC packs one Kryo 680 prime core (ARM Cortex X1-based) clocked at 2.84GHz, three Kryo 680 performance cores (ARM Cortex A78-based) clocked at 2.4GHz, and four Kryo 680 efficiency cores (ARM Cortex A55-based) clocked at 1.8GHz.

The SoC packs an Adreno 660 GPU, Qualcomm’s new Spectra 580 ISP, and the Snapdragon X60 integrated 5G modem. The SoC on both phones is paired with either 8GB or 12GB of LPDDR5 RAM and either 128GB or 256GB of fast UFS 3.1 storage. Unfortunately, the devices don’t feature a microSD card slot for further expansion.

As we expected, the OnePlus 9R packs Qualcomm’s new Snapdragon 870 chip. It’s a minor upgrade over the company’s flagship Snapdragon 865 chip from last year, featuring a slightly higher clocked prime core. The octa-core SoC packs on Kryo 585 prime core clocked at 3.2Ghz, three Kryo 585 performance cores clocked at 2.4Ghz, and four Kryo 385 efficiency cores clocked at 1.8GHz. It also features the Adreno 650 GPU and the Snapdragon X55 modem.

Cameras

The OnePlus 9 and the OnePlus 9 Pro come with a couple of noteworthy improvements on the camera front. The devices pack impressive new camera hardware, a new Natural Color Calibration profile developed in collaboration with Hasselblad, a flagship-level ultra-wide camera, and many more software features.

OnePlus 9

The OnePlus 9 features a triple-camera setup on the back and a single front-facing shooter. The main camera on the phone uses a 48MP Sony IMX689 sensor. It has an f/1.8 aperture, features electronic image stabilization, and offers multi autofocus support (All Pixel Omni-Directional PDAF+CAF). It also offers 12-bit RAW support and dual native ISO.

The primary camera is paired with a 50MP Sony IMX766 wide-angle camera that features a Freeform Lens to reduce edge distortion. It has an f/2.2 aperture, and it can even act as a high-res macro camera capable of focusing from as close as 4cm from the subject. The camera island on the back also houses a 2MP monochrome camera that works with the main 48MP shooter to add detail to monochrome photos. Over on the front, the phone packs a 16MP f/2.4 Sony IMX471 sensor with electronic image stabilization.

OnePlus 9 Pro

While the OnePlus 9 Pro also features a 48MP main camera, it uses a Sony IMX789 sensor instead of the IMX689 sensor. The main camera has an f/1.8 aperture, features both electronic and optical image stabilization, and offers the same autofocus system as on the non-Pro variant. It also offers 12-bit RAW support, dual native ISO, and DOL-HDR.

The phone features the same 50MP Sony IMX766 wide-angle camera with a freeform lens and the same 2MP monochrome sensor. However, it includes an additional telephoto camera on the back. This camera has an f/2.4 aperture and optical image stabilization. It offers 3.3x optical zoom and 30x digital zoom.

OnePlus 9R

The OnePlus 9R takes a major hit in the camera department. While it does offer a quad-camera setup, it isn’t nearly as good as the one found on the other two models. The phone features a 48MP f/1.7 Sony IMX586 primary camera with PDAF and CAF, a 16MP f/2.2 Sony IMX481 wide-angle camera with a 123° FoV, a 5MP macro camera, and a 2MP monochrome camera.

While the rear-facing camera setup isn’t that impressive, the OnePlus 9R features the same front-facing shooter as the other two models. It’s a 16MP f/2.4 Sony IMX471 sensor that offers electronic image stabilization.

Battery & Charging

Although the OnePlus 9 and 9 Pro pack the same 4,500mAh battery, they don’t feature the same fast charging capabilities. The vanilla OnePlus 9 supports 65W wired fast charging, which is capable of getting the 4,500mAh battery from 1% to 100% in just 29 minutes with the included Warp Charge 65T charger. The model heading to the North American and European markets also gets 15W Qi wireless charging support. However, the Indian and Chinese models won’t offer wireless charging capabilities.

The OnePlus 9 Pro also offers 65W wired fast charging support that can get the battery from 1-100% in just 29 minutes. Unlike the OnePlus 9, it also features 50W wireless fast charging support, which can charge the phone from 1-100% in merely 43 minutes. Thankfully, OnePlus isn’t making any region-specific alterations on the OnePlus 9 Pro, and all units will come with 50W wireless fast charging support.

The Warp Charge 65T charger that comes with the OnePlus 9 phones has also received some improvements of its own. It’s capable of charging non-OnePlus devices at up to 45W using USB PD or PPS. This is an excellent addition for those of you who have laptops that charge via a USB Type-C port, as you won’t have to carry an additional charger whenever you’re on the move.

The OnePlus 9R also features a 4,500mAh battery that supports 65W wired fast charging. The device doesn’t offer any wireless charging support, but it does come with a 65W fast charger in the box. Sadly, the fast charger included with the OnePlus 9R doesn’t support fast charging using USB PD or PPS.

5G & Connectivity

Since both the OnePlus 9 and 9 Pro pack Qualcomm’s Snapdragon 888 SoC, they feature an integrated Snapdragon X60 modem. Therefore, both devices offer 5G capabilities. But there are a couple of regional differences. The North American variant of the OnePlus 9 only gets sub-6GHz 5G support; the OnePlus 9 Pro gets mmWave support as well. The European, Indian, and Chinese models of both devices come with only sub-6GHz 5G support.

Along with 5G, both devices get 4×4 MIMO LTE support, dual-band Wi-Fi 6, Bluetooth 5.2, and NFC. The OnePlus 9 series also features dual-band GPS support, GLONASS, dual-band Galileo, Beidou, and A-GPS for positioning.

The OnePlus 9R features the Snapdragon X55 modem for 5G and LTE connectivity. But it only supports sub-6GHz 5G. Along with that, the device features 4×4 MIMO LTE support, dual-band Wi-Fi 6, and Bluetooth 5.1. For position, the phone offers dual-band GPS support, GLONASS, dual-band Galileo, Beidou, and A-GPS.

OxygenOS 11 based on Android 11

On the software front, the OnePlus 9, the OnePlus 9 Pro, and the OnePlus 9R run OxygenOS 11 based on Android 11 out of the box. The release is pretty much the same as the one that rolled out for a few older OnePlus devices over the last few months. But it includes a couple of additional features.

The devices come with the new Pro Gaming Mode, which recently started rolling out to older OnePlus phones. They also feature a new Turbo Boost 3.0 memory optimization feature that lets you keep 25% more apps open in the background by allocating some of the internal storage as RAM.

OnePlus has also revealed that it will provide two major Android upgrades to the OnePlus 9 lineup and three years of security patches delivered bi-monthly.

Accessories

Cases

OnePlus has also launched a couple of new first-party cases with the OnePlus 9 lineup. These include a Karbon Protective case that features a carbon fiber finish on the back, a Sandstone Bumper case featuring the classic OnePlus Sandstone finish, and a silver Droid Case.

Warp Charge 50 Wireless charger

OnePlus has also launched a Warp Charge 50 Wireless charger for the OnePlus 9 Pro. It can charge the phone from 1-100% in just 43% minutes and it features two charging coils, allowing you to charge the phone in both portrait and landscape orientation.

What is Confidential Computing and What is the use of it?

2021-03-26T09:18:00.003+05:30

Confidential computing provides privacy protection during the storage process and provides end-to-end cloud data protections in combination with disc and network encryption and proprietary encryption keys.

What is Confidential Computing?

Confidential computing is a cloud-based system that isolates confidential data during computation in a secure CPU enclave. The material of the enclave – data processing and processing methods – is only available to a permitted code, and inaccessible and unknown for everyone, even the cloud provider.

Data protection in the cloud is important because businesses increasingly rely on public and hybrid cloud providers. The primary objective of secretive computing is to ensure businesses that their data in the cloud is safe and confident and to promote the transfer of greater sensitivities to public cloud providers with respect to their critical data and computing workloads.

Cloud vendors have provided security facilities for years for data protection at rest (in servers and databases) and transit data (moving over a network connection). Data confidentiality risk is eliminated from confidential computation by shielding data in usage — i.e. during compilation and execution.

How confidential computing works?

Before it can be processed by an application, data must be unencrypted in memory. This leaves the data vulnerable just before, during, and just after processing to memory dumps, root user compromises, and other malicious exploits.

Confidential computing solves this problem by leveraging a hardware-based trusted execution environment, or TEE, which is a secure enclave within a CPU. The TEE is secured using embedded encryption keys, and embedded attestation mechanisms that ensure the keys are accessible to authorized application code only. If malware or other unauthorized code attempts to access the keys – or if the authorized code is hacked or altered in any way – the TEE denies access to the keys and cancels the computation.

Sensitive data will therefore be kept secure in memory before TEE is informed by the program to decrypt it for processing. The data is invisible to the operating system (or a virtual hypervisor), other computer stack tools, and the vendor and its staff as it is decrypted and during the entire computing phase.

Why use confidential computing?

· To secure even during usage confidential data and increase the advantages of cloud computing to sensitive workloads. Used in conjunction with data encryption during the rest and transit, confidential computing removes the biggest hurdle from an inflexible and costly IT architecture in a more scalable and modern public cloud platform to the mobility of critical or heavily controlled data sets and application workloads.

· For the Protection of Intellectual property security. Confidential computing is not just for the security of information. In the TEE, patented organization logic, analytical features, machine learning algorithms or whole systems can be covered.

· Working securely on emerging cloud solutions for collaborators. For instance, one company may use the patented equations of another company to merge its confidential information with new solutions – without exchanging data or intellectual property.

· Remove problems when selecting cloud services. Confidential computing lets an organization choose a cloud computing provider that meets the technological and business needs most effectively, without caring about user information, proprietary technologies, and other confidential properties.

· To safeguard data on the edge. Edge computer is a distributed computing environment that connects business systems with sources of data, such as IoT devices or local edge servers. As it is used to secure the data and operation of edge nodes of sensitive computing as part of distributed cloud trends.

What is an IP Address?

2021-03-25T19:52:00.002+05:30

What exactly is an IP?

An IP address is a number string that is divided into periods. There are four IP addresses, one example of which maybe 192.159.1.38. There will be between 0 and 255 in each number in the package. The entire set of IP addresses is therefore 0.0.0.0 to 255.255.255.255, respectively.

Not arbitrary IP addresses. The Internet Assigned Numbers Authority (IANA), an Internet corporate division for assigned names and numbers, produces and assigns them mathematically (ICANN). ICANN is a non-profit organization set up in the USA in 1998 in order to help preserve internet security and make it accessible to everyone. Whenever anyone signs a domain on the Internet, they pass a domain name registrar who pays ICANN a nominal fee for registering the domain.

Working of IP Address:

It lets you consider the manner in which an IP addresses function whether you try to figure out whether your network is not connected in the way you would expect or why your network is not running.

By talking in a series of guidelines to carry on knowledge the Internet Protocol functions like in any other language. Both devices search, send, and share information using this protocol with other wired devices. Any machine in any place will communicate with each other by speaking the same language.

This is How the IP process works:

· Your computer can connect indirectly to the internet by first linking to the internet network and then allowing your device an internet connection.

· If you are at home, the internet service provider would usually be the network (ISP). It’s the business network at work.

· Your IP is allocated by your ISP to your computer.

· You can use your IP address and your internet operation passes through the ISP. It is their duty to grant an IP address to your computer, as they give you Internet access.

· Your IP address can get change, however. For one, it can be changed by turning on or off your modem or router. Or you can contact and change your ISP for yourself.

· You don’t have your home IP address if you’re out and about – traveling for example, and taking your laptop with you. You would have to use a network other than a hotel, an airport, or a coffee store (Wi-Fi), and have another IP address, which is registered to the hotel’s ISP, the airport, or a coffee shop.

OnePlus 9R will be an affordable gaming flagship meant for India, says Pete Lau

2021-03-18T08:20:00.000+05:30

We’ll finally see the OnePlus9 series completely unveiled on March 23, just a few days from now. While we’re expecting the event to reveal details for the OnePlus 9 and the OnePlus 9 Pro, the company apparently has a third smartphone up its sleeve: the OnePlus 9R.

In an interview with News 18, OnePlus CEO Pete Lau confirmed the entry-level model — what we thought was the OnePlus 9 Lite — will launch in India. According to Lau, the OnePlus 9R is a step up from something like the OnePlus Nord, which has been very successful in India.

“With the OnePlus 9R, we are looking to go even further to bring out a balanced handset with the latest technology and class-leading industrial design that can deliver a superior user experience overall and can also offer fast and smooth experiences for daily usage and heavy gameplay,” Lau said.

Lau said the OnePlus 9R will feature “the latest technologies” you’d expect in flagship devices along with immersive gaming controls. Clearly, the device is going after a specific audience while still offering the kind of features OnePlus devices are known for, including a “fast and smooth user experience,” according to Lau.

Not much else is known about the OnePlus 9R except that it will have 5G connectivity. If OnePlus wants to keep the device down in price, we can probably rule out a Snapdragon 888 chip, which has been confirmed to appear in the OnePlus 9 and OnePlus 9 Pro. Other specs, including RAM, storage, battery, and camera, are still unknown.

OnePlus has revealed a lot about the OnePlus 9 Pro over the last few weeks, like the fact it’ll come equipped with an adaptive refresh display that can go from 1-120Hz. The OnePlus 9R has been kept more under wraps.

NSPCC request Facebook to stop encryption plans

2020-02-06T18:19:00.000+05:30

Child-protection organisations say Facebook's decision to strongly encrypt messages will give offenders a place to hide.

The company is moving ahead with plans to implement the measure on Facebook Messenger and Instagram Direct.

But more than 100 organisations, led by the NSPCC, have signed an open letter warning the plans will undermine efforts to catch abusers.

Home Secretary Priti Patel said she "fully supported" the move.

she said: "Tech companies like Facebook have a vital responsibility to balance privacy with the safety of vulnerable children."

"I fully support the continued efforts of the NSPCC and children's charities around the world to engage Facebook on this issue."

End-to-end encryption, already used on Facebook-owned WhatsApp, means no-one, including the company that owns the platform, can see the content of sent messages.

Those signing the letter say Facebook has failed to address concerns about child safety.

The missive urges the company to stop the rollout of its plans until "sufficient safeguards" are in place.

"At a time when we could be looking to build upon years of sophisticated initiatives, Facebook instead seems inclined to blindfold itself," the letter says.

"We request you to recognise and accept that an increased risk of child abuse being facilitated on or by Facebook is not a reasonable trade-off to make.

"Children should not be put in harm's way either as a result of commercial decisions or design choices."

'Safety first'

A spokesman for Facebook said protecting the well being of children on its platform was "critically important" to it.

"We have led the industry in safeguarding children from exploitation and we are bringing this same commitment and leadership to our work on encryption," he said.

"We are working closely with child-safety experts, including NCMEC [the US National Center for Missing and Exploited Children], law enforcement, governments and other technology companies, to help keep children safe online."
