3 Main Pillars in ReactJS

Aggregated on: 2023-03-10 15:44:54

In this article, I am going to explain ReactJS and the three main pillars of ReactJS, which are component, state, and props. ReactJS ReactJS is an open-source front-end technology. It is a Javascript library for developing UI components. It is a single-page application, and we can use it as a multi-page application, also. Facebook introduced ReactJS. Javascript and other libraries are very slow for updating or loading DOM, but ReactJS is faster for updating and loading DOM. So ReactJS has good performance than other libraries. It is more flexible. ReactJs introduced Virtual DOM. For example, suppose we want to create an e-commerce application in general. In that case, we start by creating individual pages and multiple components like a dashboard page (button, link, text, image, etc.) and a home page(button, link, text). Still, by using React, we can create custom components for some of the widely used elements like buttons or Texts that can be made reusable in the entire application. To be more specific, the Text box has properties like length, size, validations, shades, and other properties, but to keep the end user interactive, we always use a particular style and stick to it. Hence customizing and reusing makes a lot of sense.

Collaborative Development of New Features With Microservices

Aggregated on: 2023-03-10 14:29:54

In a microservices architecture, code is broken into small units. These pieces of code can be developed in isolation and shipped independently to production, which reduces dependencies between teams—the result: is rapid feature development and faster time to market. While a microservices architecture brings many benefits, the reality is that these benefits tend to diminish at scale. In particular, the more microservices that an organization has, the harder it is to ensure that changes work together as a whole.

Testing Your Monitoring Configurations

Aggregated on: 2023-03-09 20:59:54

Monitoring is a small aspect of our operational needs; configuring, monitoring, and checking the configuration of tools such as Fluentd and Fluentbit can be a bit frustrating, particularly if we want to validate more advanced configuration that does more than simply lift log files and dump the content into a solution such as OpenSearch. Fluentd and Fluentbit provide us with some very powerful features that can make a real difference operationally. For example, the ability to identify specific log messages and send them to a notification service rather than waiting for the next log analysis cycle to be run by a log store like Splunk. If we want to test the configuration, we need to play log events in as if the system was really running, which means realistic logs at the right speed so we can make sure that our configuration prevents alerts or mail storms. The easiest way to do this is to either take a real log and copy the events into a new log file at the speed they occurred or create synthetic events and play them in at a realistic pace. This is what the open-source LogGenerator (aka LogSimulator) does. I created the LogGenerator a couple of years ago, having addressed the same challenges before and wanting something that would help demo Fluentd configurations for a book (Logging in Action with Fluentd, Kubernetes, and more).

Create a REST API in C# Using ChatGPT

Aggregated on: 2023-03-09 19:59:54

ChatGPT is a cutting-edge natural language processing model created by OpenAI, an artificial intelligence research center founded by Elon Musk, Sam Altman, and Greg Brockman. The model was announced in June 2018, and has continuously been modified and upgraded, with the most recent version, GPT-3, being released in 2020. ChatGPT was made from GPT-3, and was released back in 2022. The “GPT” in ChatGPT stands for “Generative Pre-trained Transformer,” a reference to the model’s deep learning architecture. ChatGPT essentially uses massive amounts of text data to “learn” the intricacies of human language, allowing it to create replies that are frequently impossible to differentiate from those of humans. The ChatGPT technology is based on a type of neural network known as a transformer, which is well-suited to natural language processing applications. ChatGPT’s capacity to create high-quality output to a wide range of prompts you give in the chat box is one of its key features. The response you get feels like it has been generated by a human. You can also specify the conditions of your request. The model was trained on a vast corpus of text, so it can rely on a wide range of data to answer questions, provide information, or participate in casual conversation generated from its neural network. It is crucial to remember; however, that ChatGPT is not flawless. When faced with suggestions that are beyond the model’s area of knowledge, the model may provide illogical or unsuitable replies. ChatGPT usage is sometimes high, and, because of this, there can sometimes be a limit to how many queries you can send.

Is DevOps Dead?

Aggregated on: 2023-03-08 22:14:53

What Exactly Is DevOps Anyway? Way back in 2006, Amazon CTO Werner Vogels got the ball rolling when he famously said, “Giving developers operational responsibilities has greatly enhanced the quality of the services, both from a customer and a technology point of view. The traditional model is that you take your software to the wall that separates development and operations, throw it over, and then forget about it. Not at Amazon. You build it; you run it. This brings developers into contact with the day-to-day operation of their software.” While the “you build it, you run it” mantra has become synonymous with DevOps, the actual application has not been so clear for many organizations. Dozens of articles and Reddit posts would seem to indicate that there is a very big range of opinions on this topic.

AWS Multi-Account Strategy and Landing Zone

Aggregated on: 2023-03-08 19:59:53

AWS multi-account strategy is a powerful method of managing multiple AWS accounts within an organization. It is designed to help organizations scale and manage their cloud infrastructure more effectively while maintaining security and compliance. In this article, we will explore the key components of an AWS multi-account strategy and how it can be implemented to achieve better control and efficiency in managing cloud resources. Why Multiple Accounts? Security controls: Each application could have different security controls, like within same organization, PCI-DSS will have different security controls than other applications. Isolation: Isolation is crucial to prevent potential risks and security threats that may arise from having multiple applications in the same account. Many teams: Using multiple accounts prevents team interference, as teams with different responsibilities and resource needs are separated. Data Isolation: Isolating data stores to an account limits access and management of data to a select few, reducing the risk of unauthorized exposure of sensitive information. Business process: Individual accounts can be created to cater to specific business needs since business units or products often have different purposes and processes. Billing: The multi-account approach allows for the creation of distinct billable items across business units, functional teams, or individual users. Quota allocation: Each account, including projects, has a well-defined and individual quota since AWS quotas are established on a per-account basis. Design OU Structure An organizational unit (OU) is a logical grouping of accounts in your organization, created using AWS organizations. OUs enable you to organize your accounts into a hierarchy and make it easier for you to apply management controls. AWS organizations policies are what you use to apply such controls. A Service Control Policy (SCP) is a policy that defines the AWS service actions.

Learning Adaptability A few weeks ago, my laptop crashed during a meeting. It was painful as I was about to start on an exciting new feature that my Product Owner (PO) had just proposed. I immediately rushed to the IT department for assistance, and they informed me that they needed to take a backup and completely rebuild my laptop. They estimated that rebuilding would take slightly over a half day to complete. Feeling frustrated, I asked myself: “Can I code without my laptop?”. In the past, I would have answered ‘NO’ without hesitation. But on second thought, I realized that I know my system well and am also familiar with the domain. After more introspection, I recognized that I was already doing it without consciously realizing it. So, I went to my PO and requested him to print the new requirements for me. From Requirements to Success Criteria There are numerous factors that a software engineer must consider before writing even a single line of code. First and foremost is understanding the business problem and who the actors are. Once you have a clear understanding of the requirements, it enables you to identify any flaws in the requirements or if it contradicts any existing features. You can then break it down into manageable pieces and think about how to reuse those pieces or determine if something already exists. This process helps you to define the final success criteria.

Optional in Java: A Swiss Army Knife for Handling Nulls and Improving Code Quality

Aggregated on: 2023-03-08 17:44:53

In Java, dealing with null values can be a real headache. Nulls can cause all sorts of problems in your code, from NullPointerExceptions to convoluted if statements and error-prone logic. Fortunately, Java 8 introduced the Optional class, which offers a simple and powerful way to handle nulls and improve code quality. Optional is a container object that may or may not contain a non-null value and provides a range of practical methods for working with its contents. In this article, we'll explore the many use cases of Optional in Java and show you how to use this powerful class to write cleaner, more expressive, and more resilient code. So let's deep dive into a few examples of uses of Optionals. Avoiding NullPointerExceptions One of the most common use cases of Optional is to avoid NullPointerExceptions. By wrapping a potentially null value in an Optional, you can safely access the value without risking a NullPointerException. For example, if you have a method that returns a value that might be null, you can return an Optional instead and then use Optional methods to access the value safely.

Introduction to Automation Testing Strategies for Microservices

Aggregated on: 2023-03-08 15:14:53

Microservices are distributed applications deployed in different environments and could be developed in different programming languages having different databases with too many internal and external communications. Therefore, a microservices architecture is dependent on multiple interdependent applications for its end-to-end functionalities. This complex microservices architecture requires a systematic testing strategy to ensure end-to-end (E2E) testing for any given use case. In this blog, we will discuss some of the most adopted automation testing strategies for microservices, and to do that, we will use the testing triangle approach. Testing Triangle It's a modern way of testing microservices with a bottom-up approach, which is also part of the "Shift-left" testing methodology (The "shift-left" testing method pushes testing towards the early stages of software development. By testing early and often, you can reduce the number of bugs and increase the code quality.). The goal of having multiple stacked layers of the following test pyramid for microservices is to identify different types of issues at the beginning of testing levels. So, in the end, you will have very few production issues. Each type of testing focuses on a different layer of the overall software system and verifies expected results. For a distributed microservices app, the tests can be organized into the following layers using a bottom-up approach:

What Is the AWS Lambda Cold Start Problem? AWS Lambda is a serverless computing platform that enables developers to quickly build and deploy applications without having to manage any underlying infrastructure. However, this convenience comes with a downside—the AWS Lambda cold start problem. This problem can cause delays in response times for applications running on AWS Lambda due to its cold start problem, which can affect user experience and cost money for businesses running the application. In this article, I will discuss what causes the AWS Lambda cold start problem and how it can be addressed by using various techniques.

Donald Knuth famously wrote that Premature Optimization is the root of all evil. I, for one, believe that all evil comes from spuriously failing builds. Nothing steals my confidence in a project as quickly as unstable builds alternating between green and red for no reason. This is a story about unstable builds and troubleshooting. More importantly, this story is written to thank all contributors to basic software infrastructure — the infrastructure we all use and take for granted. Surprise in Logs Upon logging into Azure Pipelines to review the logs of multiple failed builds, I mentally braced myself for a potentially arduous troubleshooting session. I suspected that a race condition was the culprit that caused non-deterministic outcomes. Therefore, I was surprised to discover the actual reasons for the recent build failures. They were all similar to this:

Understanding How Stream Processing Works

Aggregated on: 2023-03-07 23:44:52

With constant digital evolution, the sources of streaming data are rising, such as IoT, networked devices, online activities of various kinds, server log files, and so on. And with every industry becoming reliant on this data to unlock data-driven business insights, streaming processing systems power everything from real-time fraud detection, stock trading platforms, and sentiment analysis from social media feeds to multiplayer games and GPS tracking. However, streaming data is generated at very high velocities by many data sources. Thus, it can be challenging to build robust stream processing solutions. This article describes how stream processing works and the fundamental building blocks of its architecture.

Aggregated on: 2023-03-07 23:44:52

Previous Articles on Multi-Region CockroachDB Multi-Region Abstractions for MongoDB Developers With FerretDB Motivation I was working with a prospect on a use case where my knowledge of CockroachDB multi-region abstractions was put to the test. After trying and failing to gain low latency write behavior from a geographically distributed table, I reached out to the engineering team who corrected my understanding. This is my way of documenting my understanding and committing it to memory.

GraphQL Frameworks

Aggregated on: 2023-03-07 22:14:52

GraphQL is a popular query language that allows developers to efficiently query data by specifying the data they need and how it should be structured. The language is independent of any specific database or storage mechanism and can be used with a variety of frameworks to create robust, scalable APIs. Unlike REST APIs, GraphQL provides a single endpoint for all requests, making it easier to develop and maintain APIs. There are several frameworks available to implement GraphQL, each with its own pros and cons.

Dependency Injection and Ways to Inject It Using .NET Core API

Aggregated on: 2023-03-07 21:14:52

In this article, we are going to discuss dependency injection and its usage and benefits. We will also discuss different ways to implement dependency injection. Prerequisites Basic understanding of the C# programming language. Understanding of Object-Oriented programming. Basic understanding of .NET Core. Purpose of the Dependency Injection Design Pattern In simple words, dependency means the object depends on another object to do some work. Using dependency injection, we can write loosely coupled classes and, because of that, our current functionality of one class does not directly depend on another class because we can easily maintain, change, and unit test code properly. It also takes care of the open-closed principle. Using abstraction and interface, we can make some future changes easily without modifying existing functionality.
