1,921,710 | How to deploy refactored mainframe applications on AWS | Note: ✋ This post was originally published on my blog wiki-cloud.co ... | 0 | 2024-07-12T22:20:38 | https://wiki-cloud.co/en/2024/07/how-to-deploy-refactored-mainframe-applications-aws/ | aws, cloud, mainframe, application | >**Note:** ✋ This post was originally published on my blog [wiki-cloud.co](https://wiki-cloud.co/en/2024/07/how-to-deploy-refactored-mainframe-applications-aws/)
## **Introduction**
Application modernization has become a priority for many companies seeking to improve their operational efficiency, their ability to quickly adapt to market changes and remain competitive in an increasingly digital and dynamic business environment. For many companies, it becomes a challenge to migrate and modernize legacy applications, such as mainframe applications to agile and flexible environments such as the AWS cloud. However, with the tools and solutions that AWS provides, this process becomes much easier.
In this article, I will explain a step-by-step on how to deploy a mainframe application that has already been analyzed and refactored. This implies that the original COBOL code has been transformed into a modern language such as JAVA. We will carry out the deployment in an runtime environment in AWS using the service of **AWS Mainframe Modernization**.
## **AWS Mainframe Modernization**
In a previously [article](https://dev.to/aws-builders/say-goodbay-to-the-past-and-modernize-your-mainframe-with-aws-587b) I gave an introduction to the AWS Mainframe Modernization service, which is basically a set of services and tools designed to facilitate the migration and modernization of applications and workloads running on mainframes to the AWS cloud.
Within this set of tools we have **AWS Blu Insights** which is a SaaS type tool and helps us not only analyze mainframe applications but also carry out the transformation and/or refactoring of these legacy applications that are developed with the COBOL language to more modern languages such as JAVA, preserving their original logic and functionalities.
When we carry out the transformation and/or refactoring process of these mainframe applications with AWS Blu Insights, we must take into account that the result of this process is the generation of a JAVA application mainly with two layers (Frontend and Backend) and open to a additional layer of persistence where we can make use of other services that AWS provides us such as databases, file storage and queue management services.
## **Deploying refactored mainframe applications**
For this demo we download the example application that AWS has called [Planets Demo](https://d3lkpej5ajcpac.cloudfront.net/demo/bluage/PlanetsDemo-v1.zip), this application has already gone through the refactoring process so it is ready to be deployed in the AWS Mainframe Modernization service.
To deploy the application we must follow the following steps:
- **<u>Step 1 – Create an S3 bucket and upload the application</u>**
As a first step, must create a bucket in S3 where upload the already refactored application that is in ZIP format so that the AWS Mainframe Modernization service is able to take it and process it within its execution engine.
Something to take into account is that the bucket must be created in the same region where the application deployment in the AWS Mainframe Modernization service will be created and the ZIP file must be stored within a folder.
- **<u>Step 2 – Defining the application</u>**
As a requirement to deploy a refactored mainframe application to the AWS Mainframe Modernization service, a JSON file must be configured where the location and configuration of the application is defined, so that the AWS Migration Modernization service takes these parameters and the deployment process runs correctly on the service execution engine.
The configuration is very simple and for this example in the following JSON code we configure the name of the bucket, the path where the ZIP file is located within this bucket and the port where the application will be listened to when the URL is entered in a browser.
```
{
"template-version": "2.0",
"source-locations": [{
"source-id": "s3-source",
"source-type": "s3",
"properties": {
"s3-bucket": "demo-aws-mainframe-modernization",
"s3-key-prefix": "PlanetsDemo/v1"
}
}],
"definition": {
"listeners": [{
"port": 8194,
"type": "http"
}],
"ba-application": {
"app-location": "${s3-source}/PlanetsDemo-v1.zip"
}
}
}
```
Once the configurations have been made in the JSON file, it is important to upload it to the same folder within the Bucket where the ZIP file has already been uploaded with the refactored application.
- **<u>Step 3 – Creating the runtime environment in AWS Mainframe Modernization</u>**
A runtime environment is a comprehensive set of infrastructure resources that includes a runtime engine, specifically designed to host and manage one or more migrated mainframe applications.
To create the runtime environment, the first thing we do is look for the AWS Mainframe Modernization service within the AWS console and there we select the “Refactor with Blu Age” option.
In this demo, the application has already gone through the refactoring process with the solution of [Blue Age](https://www.bluage.com/), what we're going to do now is perform the deployment of the mainframe application in the execution engine. For this we select the deployment option and after the select the runtime environment option.
Now we ask ourselves, what is refactoring? As the service page says “It is the automatic transformation of legacy language applications (e.g. COBOL) into agile services based on Java with AWS Blu Age, taking advantage of the most advanced web frameworks and best practices of DevOps in the cloud.”
We select the deployment option, then “create runtime environment” and finally click on the continue button.
Another way to access the creation of this runtime environment is by entering through the menu on the left, selecting the "Environments" option.
Regardless of the path by which we access to the creation of the runtime environment, the first step is is to specify the basic information, where we give a name and a description to the runtime environment.
Now it asks us to select the engine, as this is an application that has already gone through the refactoring process with the Blu Age tool, we must select this engine and the version, for the purposes of this demonstration we will select the one that appears by default which is version 3.70, however it is recommended to work with the latest versions that come with many improvements and updates.
At the end of this basic information specification, the same service page indicates that once the runtime environment is created, metrics will automatically be created and logs stored in Amazon CloudWatch. If desired, you can also apply tags.
Now we move on to step 2, which is the configuration specification, in this section we configure the availability of the runtime environment, where the AWS Mainframe Modernization service offers two options: the standalone runtime environment and the high availability cluster. In the standalone runtime environment, a single instance is configured in an availability zone, a perfect scenario for demos like this and to test mainframe applications already transformed and refactored, in the case of the high availability cluster it is recommended for production environment scenarios where we will have redundant instances in two availability zones, of course this scenario is more expensive.
For this demo we will select the standalone runtime environment option.
Another section is the resources part where we select the type of instance we want to be deployed for our runtime environment. AWS Mainframe Modernization offers a series of instance types that we can use depending on the type of workload or application that we are going to process in the runtime engine. For this demo we will use the smaller one, which is the M2.m5.large instance.
Finally, we move on to the security and networking section, where we select the VPC, subnets, and security groups we want to use to deploy these instances. For this demo we selected the option "Allow applications deployed in this environment to be publicly accessible", this option assigns a public IP address to the application so that it can be accessed from a web browser.
The next step is to select the storage. If our mainframe application requires storage such as EFS or FSx, we can configure it in this option. For this demo these types of storage will not be necessary.
Now we move on to scheduling maintenance, as AWS Mainframe Modernization is a managed service, AWS is responsible for performing maintenance and applying updates, however we must select when these maintenance windows should be scheduled so as not to affect the operation of the mainframe applications that are already deployed. For this demo we will select the no preference option.
To finish the creation of our runtime environment, a summary of the selected configuration is displayed to make a final check before creating the environment. In this demo the creation of the runtime environment took approximately 4 to 5 minutes.
- **<u>Step 4 – Create the mainframe application</u>**
In this step what we do is configure the mainframe application that we want to deploy.
Step 1 of this section is the specify basic information, where we give our application a name, a description and select the type of engine which in this case is Blu Age.
Additionally, other configuration options are offered, such as adding a KMS key, adding an IAM role and tags to assign to these resources.
Step 2 of this section refers to the specify resources and configurations, this step is key to configure properly, because the correct configuration will depend largely the sucess execution of the application. Here we simply copy the JSON code we set up previously where we defined the bucket and the path where the ZIP file is located with the refactored mainframe application or we simply select the path of the bucket where this JSON file is located.
The last step in this section is reviewing and creating the mainframe application configuration. For this demo this process took approximately 30 seconds.
- **<u>Step 5 – Deploy the mainframe application</u>**
Having already created the runtime environment and the configuration of the application, we would only need to deploy the application refactored with Blue Age in this runtime environment that we have created and configured.
To access the deployment configuration we simply click on the name of the application configuration that we have just defined for this demo "app_planetsdemo" and click on the Deploy button.
In this step all we do is select the version of our mainframe application and the runtime environment where we want to deploy it.
For this demo, this process took approximately 15 minutes to deploy the mainframe application.
- **<u>Step 6 – Run and test the application</u>**
After having completed all these steps and their respective configuration, we proceed to run and test the AWS Planets Demo example application. We are going to notice something interesting and that is that since the mainframe application has been refactored, modernizing the code from COBOL to JAVA, we will enter to the application in web mode through a browser. But before running the live application, we must start it and once started we go to the information section of the application, where we can see that a DNS Hostname has been configured and assigned, which is the address that we must enter in the web browser.
> _[View animated GIF](https://wiki-cloud.co/wp-content/uploads/2024/07/article_image_aws_deploy_refactored_mainframe_applications_23.gif)_
For many, this application will remind them of times of the past, but now they are a reality to have them in the AWS cloud and in its AWS Mainframe Modernization service. This application is very simple, we simply type in a name of a planet of the solar system and it immediately brings us information about the planet we have searched. As the application runs in a web environment we can change the appearance of the screen.
In the browser we enter the following URL: http://{DNS hostname}:{port}/PlanetsDemo-web-1.0.0/
Now let's get to the action!!

- **<u>Step 7 – Mainframe Application Monitoring</u>**
Within the application section, several tabs appear with certain information and one of them is the monitoring tab. When we enter this, different graphs are shown with metrics that measure the performance of the infrastructure and the mainframe application.

## **Conclusions**
Adopting AWS specific tools and services, such as AWS Mainframe Modernization, eases the transition process, ensuring that refactored mainframe applications retain their optimal functionality and performance. Modernizing mainframe applications on AWS not only is a technological evolution, but also an opportunity for companies to innovate and improve their operations, while maintaining their relevance and competitiveness in a constantly changing business environment. AWS provides a wide range of resources and tools that not only simplify this process, but also empower business transformation through mainframe application modernization.

1,921,715 | Mastering @Observable: Introduction to Swift Observation | 1. Introduction State management has always been a cornerstone of application development.... | 0 | 2024-07-12T22:19:19 | https://dev.to/andy_kolean/mastering-observable-introduction-to-swift-observation-268 | swift, ios, swiftui, observation | ## 1. Introduction
State management has always been a cornerstone of application development. In Swift, managing state has evolved significantly over the years. Initially, developers relied on manual state management techniques, which often led to complex and error-prone codebases. As applications grew in size and complexity, the need for more robust and maintainable state management solutions became evident.
With the introduction of frameworks like Combine and SwiftUI, there was a paradigm shift in how state is managed. Combine introduced a declarative way to handle asynchronous events, while SwiftUI leveraged a reactive approach to automatically update the user interface based on state changes. Despite these advancements, developers still faced challenges related to boilerplate code, performance, and synchronization across different parts of the app.
Starting with iOS 17, iPadOS 17, macOS 14, tvOS 17, and watchOS 10, SwiftUI provides support for the Observation framework, a Swift-specific implementation of the observer design pattern. This framework offers several benefits over the previous `ObservableObject` protocol, including the ability to track optionals and collections of objects and the use of existing data flow primitives like `State` and `Environment` instead of object-based equivalents such as `StateObject` and `EnvironmentObject`. Additionally, the Observation framework updates views based on changes to the observable properties that a view’s body reads, which can help improve app performance.
Swift's new `@Observable` macro addresses these challenges head-on. The macro is designed to simplify state management by providing a declarative and efficient way to observe changes in state and automatically update the user interface. This macro reduces the amount of boilerplate code, ensures consistent state synchronization, and enhances the performance of Swift applications.
In this post, we will delve into the specifics of the Observation framework, highlighting its key features and the problems it solves. We will also discuss the importance of observation in the context of modern Swift development and the platforms that support this framework. By the end of this post, you will have a comprehensive understanding of why the Observation framework is a significant addition to the Swift ecosystem.
---
## 2. Overview of the Observation Framework and @Observable Macro
The Observation framework in Swift is a robust, type-safe, and performant implementation of the observer design pattern. This framework allows an observable object to maintain a list of observers and notify them of specific or general state changes, thereby decoupling objects and enabling implicit distribution of updates across multiple observers.
### Definition
The Observation framework provides the following capabilities:
- **Marking a type as observable**: Using the `@Observable` macro.
- **Tracking changes within an instance of an observable type**: Using the `withObservationTracking(_:onChange:)` function.
- **Observing and utilizing those changes elsewhere**: Such as in an app’s user interface.
To declare a type as observable, attach the `@Observable` macro to the type declaration. This macro generates source code at compile time that adds observation support to the type.
### Features
**Declarative State Observation:**
- The `@Observable` macro leverages Swift's powerful declarative syntax, allowing developers to specify which types should be observable without writing extensive boilerplate code.
**Automatic UI Updates**:
- With the Observation framework, the user interface is automatically updated whenever an observed property's value changes. This ensures that the UI is always in sync with the underlying state, providing a seamless and responsive user experience.
**Type-Safe and Performant**:
- The framework is designed to be type-safe, ensuring that only valid types and properties are observed. It is also optimized for performance, reducing the overhead associated with state management.
**Integration with Existing Frameworks**:
- The Observation framework is designed to work seamlessly with existing Swift frameworks, such as SwiftUI and Combine. This integration allows developers to leverage the full power of these frameworks while benefiting from the simplified state management provided by the Observation framework.
### Example Usage
Here is a simple example to illustrate how the `@Observable` macro can be used in a Swift application:
```swift
import SwiftUI
import Combine
@Observable
class Car {
var name: String = ""
var needsRepairs: Bool = false
init(name: String, needsRepairs: Bool = false) {
self.name = name
self.needsRepairs = needsRepairs
}
}
struct ContentView: View {
@State private var car = Car(name: "Tesla")
var body: some View {
VStack {
TextField("Enter car name", text: $car.name)
Text("Car name: \(car.name)")
}
.padding()
}
}
func render(cars: [Car]) {
withObservationTracking {
for car in cars {
print(car.name)
}
} onChange: {
print("Schedule renderer.")
}
}
```
In this example:
- The `Car` class is marked as observable using the `@Observable` macro.
- The `ContentView` struct uses the `State` property wrapper to manage the `Car` object. When the `name` property changes, the `Text` view is automatically updated to reflect the new value.
- The `render` function demonstrates how to track changes using the `withObservationTracking(_:onChange:)` function. It prints the names of the cars and schedules a re-render when any car's name changes.
### Supported Platforms
The Observation framework is designed to be used across all major Apple platforms, ensuring that developers can take advantage of its benefits regardless of their target platform.
**iOS**:

### 3. Importance of Observation
The Observation framework in Swift is more than just a tool for state management; it represents a significant advancement in how developers can create responsive and efficient applications. This section explores the importance of observation in modern Swift development and the key benefits it brings to the table.
### State Management
**Role in Managing State**:
- The Observation framework simplifies state management by automating the process of tracking changes to data and updating the user interface accordingly. This ensures that the UI always reflects the current state of the application, providing a consistent and seamless user experience.
**Reduction of Boilerplate Code**:
- Traditional state management often involves extensive boilerplate code to manually track and update state changes. The Observation framework, with its `@Observable` macro, reduces this boilerplate by automatically generating the necessary code to observe changes and update the UI.
### Performance
**Efficient State Synchronization**:
- By updating views only when properties that are directly read by the view's body change, the Observation framework ensures efficient state synchronization. This selective updating reduces unnecessary re-renders, improving the overall performance of the application.
**Optimized for Reactive Programming**:
- The Observation framework leverages reactive programming principles, which are foundational to modern frameworks like SwiftUI. This integration enhances the performance and responsiveness of applications by ensuring that the UI reacts promptly to state changes.
### Flexibility and Integration
**Support for Existing Primitives**:
- The framework supports existing data flow primitives like `State` and `Environment`, allowing developers to use familiar tools while benefiting from the enhancements provided by the Observation framework. This compatibility simplifies the transition for existing projects.
**Incremental Adoption**:
- Developers can adopt the Observation framework incrementally, starting with a single data model type and gradually updating other parts of the application. This flexibility allows for a smoother transition and reduces the risk of introducing bugs during the migration process.
### Use Cases
**Tracking Optionals and Collections**:
- Unlike the `ObservableObject` protocol, the Observation framework can track optionals and collections of objects. This capability is crucial for applications that need to handle complex data structures and dependencies.
**Improved Data Flow**:
- By using observation to update views based on changes to specific properties rather than any property change, the framework improves data flow within the application. This targeted approach enhances the accuracy and efficiency of state updates.

## 4. Problems Solved by Observation
The Observation framework addresses several key challenges that developers face when managing state in Swift applications. By introducing the `@Observable` macro and other observation tools, the framework simplifies and enhances the state management process. This section highlights the primary problems solved by the Observation framework.
### Reduction of Boilerplate Code
**Eliminating Repetitive Code Patterns**:
- Traditional state management often requires extensive boilerplate code to manually track state changes and update the UI. The `@Observable` macro significantly reduces this boilerplate by automatically generating the necessary code for observing and updating properties. This automation makes the codebase more concise and easier to maintain.
**Simplifying Property Declarations**:
- The Observation framework eliminates the need for the `@Published` property wrapper. Instead, properties within an `@Observable` type are automatically tracked based on
their accessibility to observers. This change simplifies property declarations and reduces the amount of boilerplate code required.
### Ensuring State Synchronization
**Consistent State Management**:
- Managing state synchronization across different parts of an application can be complex and error-prone. The Observation framework ensures consistent state synchronization by automatically updating views when observable properties change. This automatic synchronization helps avoid state mismatches and inconsistencies, ensuring that the UI always reflects the current state.
**Selective Updates for Performance**:
- Unlike the `ObservableObject` protocol, which triggers view updates for any property change, the Observation framework updates views only when properties that are directly read by the view's body change. This selective updating reduces unnecessary re-renders and improves the overall performance of the application.
### Optimizing Performance
**Efficient State Updates**:
- The Observation framework optimizes state updates by leveraging reactive programming principles. This optimization ensures that the UI responds promptly to state changes, providing a smooth and responsive user experience.
**Reducing Overhead**:
- By minimizing the amount of code required to manage state and automating the observation process, the Observation framework reduces the overhead associated with state management. This reduction in overhead contributes to better performance and efficiency in Swift applications.
### Supporting Complex Data Structures
**Tracking Optionals and Collections**:
- One of the significant limitations of the `ObservableObject` protocol is its inability to track optionals and collections of objects effectively. The Observation framework addresses this limitation by providing robust support for tracking changes in optionals and collections. This capability is essential for applications that need to handle complex data structures and dependencies.
**Enhanced Data Flow Management**:
- The framework improves data flow management by using observation to update views based on changes to specific properties rather than any property change. This targeted approach enhances the accuracy and efficiency of state updates, leading to more reliable and maintainable applications.
---
## Conclusion
The Observation framework and the `@Observable` macro address several key challenges in state management for Swift applications. By reducing boilerplate code, ensuring consistent state synchronization, optimizing performance, and supporting complex data structures, the framework provides a powerful and efficient solution for managing state in Swift applications.
In the next post, we will delve into the basics of `@Observable` and `@ObservedObject`, exploring how these annotations simplify state management and providing examples of their usage. | andy_kolean |

## **Introducción**
La modernización de aplicaciones se ha convertido en prioridad para muchas empresas que buscan mejorar su eficiencia operativa, su capacidad para adaptarse rápidamente a los cambios del mercado y lograr mantenerse competitivas en un entorno empresarial cada vez más digital y dinámico. Para muchas empresas se convierte en un reto migrar y modernizar aplicaciones legacy, como por ejemplo las aplicaciones de mainframe a entornos agiles y flexibles como la nube de AWS, sin embargo con las herramientas y soluciones que AWS provee, este proceso se hace mucho más fácil.
En este artículo, realizaremos un paso a paso sobre cómo desplegar una aplicación mainframe que ya ha sido analizada y refactorizada. Esto implica que el código COBOL original ha sido transformado a un lenguaje moderno como JAVA. Realizaremos el despliegue en un entorno de ejecución en AWS utilizando el servicio de **AWS Mainframe Modernization**.
## **AWS Mainframe Modernization**
En un [artículo](https://dev.to/aws-espanol/despidete-del-pasado-y-moderniza-tu-mainframe-con-aws-12bl) anterior di una introducción del servicio de AWS Mainframe Modernization, que básicamente es un conjunto de servicios y herramientas diseñadas para facilitar la migración y modernización de aplicaciones y cargas de trabajo que se ejecutan en mainframes hacia la nube de AWS.
Dentro de este conjunto de herramientas tenemos **AWS Blu Insights** que es una herramienta tipo SaaS y nos ayuda no solo a analizar las aplicaciones de mainframe sino también a realizar la trasformación y/o refactorización de estas aplicaciones legacy que están desarrolladas con lenguaje COBOL a lenguajes más modernos como JAVA preservando su lógica y funcionalidades originales.
Cuando realizamos el proceso de trasformación y/o refactorización de estas aplicaciones de mainframe con AWS Blu Insights, debemos tener en cuenta que el resultado de este proceso es la generación de un aplicación JAVA principalmente con dos capas (Frontend y Backend) y abierto a una capa adicional de persistencia donde podemos hacer uso de otros servicios que nos provee AWS como las bases de datos, almacenamiento de archivos y servicios de gestión de colas.
## **Despliegue de aplicaciones mainframe refactorizadas**
Para este demo descargamos la aplicación de ejemplo que tiene AWS llamada [Planets Demo](https://d3lkpej5ajcpac.cloudfront.net/demo/bluage/PlanetsDemo-v1.zip), esta aplicación ya ha pasado por el proceso de refactorización por lo que esta lista para ser desplegada en el servicio de AWS Mainframe Modernization.
Para desplegar la aplicación debemos seguir los siguientes pasos:
- **<u>Paso 1 – Crear un bucket S3 y cargar la aplicación</u>**
Como primer paso debemos crear un bucket en S3 donde cargamos la aplicación ya refactorizada que se encuentra en formato ZIP para que el servicio de AWS Mainframe Modernización sea capaz de tomarla y procesarla dentro de su motor de ejecución.
Algo para tener en cuenta es que el bucket debe ser creado en la misma región donde se va a crear el despliegue de la aplicación en el servicio de AWS Mainframe Modernización y el archivo ZIP debe estar almacenado dentro de una carpeta.
- **<u>Paso 2 – Definición de la aplicación</u>**
Como requisito para desplegar una aplicación refactorizada de mainframe en el servicio de AWS Mainframe Modernization, se debe configurar una archivo tipo JSON donde se define la ubicación y la configuración de la aplicación, para que el servicio de AWS Migration Modernization tome estos parámetros y se ejecute correctamente el proceso de despliegue en el motor de ejecución del servicio.
La configuración es muy sencilla y para este ejemplo en el siguiente código JSON configuramos el nombre del bucket, la ruta donde se encuentra el archivo ZIP dentro de este bucket y el puerto por donde va a ser escuchada la aplicación cuando se digite la URL en un navegador.
```
{
"template-version": "2.0",
"source-locations": [{
"source-id": "s3-source",
"source-type": "s3",
"properties": {
"s3-bucket": "demo-aws-mainframe-modernization",
"s3-key-prefix": "PlanetsDemo/v1"
}
}],
"definition": {
"listeners": [{
"port": 8194,
"type": "http"
}],
"ba-application": {
"app-location": "${s3-source}/PlanetsDemo-v1.zip"
}
}
}
```
Una vez realizadas las configuraciones en el archivo JSON, es importante cargarlo en la misma carpeta dentro del Bucket donde ya se ha cargado el archivo ZIP con la aplicación refactorizada.
- **<u>Paso 3 – Creación del entorno de ejecución en AWS Mainframe Modernization</u>**
Un entorno de ejecución es un conjunto integral de recursos de infraestructura que incluye un motor de ejecución, diseñado específicamente para alojar y gestionar una o varias aplicaciones de mainframe migradas.
Para crear el entorno de ejecución lo primero que hacemos es buscar el servicio de AWS Mainframe Modernization dentro de la consola de AWS y allí seleccionamos la opción “Refactor con Blu Age”.
En este demo, la aplicación ya paso por el proceso de refactorización con la solución de Blue Age, lo que vamos a hacer ahora es realizar el despliegue de la aplicación de mainframe en el motor de ejecución del servicio. Para esto seleccionamos la opción de despliegue y la opción crear entorno de ejecución.
Ahora nos preguntamos, qué es la refactorización?, como bien dice la página del servicio “Es la transformación automática de aplicaciones de lenguajes heredados (Ej. COBOL) en servicios ágiles basados en Java con AWS Blu Age, aprovechando los marcos web más nuevos y las mejores prácticas de DevOps en la nube.”
Seleccionamos la opción despliegue, luego “crear entorno de ejecución” y por último continuar.
Otra forma de acceder a la creación de este entorno de ejecución es ingresando por el menu de la izquierda, seleccionando la opción “Environments”.
Independiente del camino por donde accedamos a la creación del entorno de ejecución, se llega al primer paso que es especificar la información básica, donde damos un nombre y una descripción al entorno de ejecución.
Ahora nos solicita que seleccionemos el motor, como esta es una aplicación que ya paso por el proceso de refactorización con la herramienta de Blu Age, debemos seleccionar este motor y la versión, para efectos de esta demostración seleccionaremos la que nos aparece por defecto que es la versión 3.70, sin embargo se recomienda trabajar con últimas versiones que vienen con muchas mejoras y actualizaciones.
Al finalizar esta especificación de información básica, la misma página del servicio indica que una vez sea creado el entorno de ejecución, automáticamente se van a crear métricas y almacenar logs en Amazon CloudWatch. Si se desea también se puede aplicar tags.
Ahora pasamos al paso 2 que es la especificación de la configuración, en esta sección configuramos la disponibilidad del entorno de ejecución, donde el servicio de AWS Mainframe Modernization ofrece dos opciones que son el entorno de ejecución standalone y el clúster de alta disponibilidad. En el entorno de ejecución standalone se configura una única instancia en una zona de disponibilidad, escenario perfecto para demos como esta y para probar aplicaciones de mainframe ya transformadas y refactorizadas, en el caso de del clúster de alta disponibilidad se recomienda para escenarios de entorno de producción donde tendremos instancias redundantes en dos zonas de disponibilidad, por supuesto este escenario es más costoso.
Para este demo seleccionaremos la opción de entorno de ejecución standalone.
Otra sección es la parte de recursos donde seleccionamos el tipo de instancia que queremos que se despliegue para nuestro entorno de ejecución. AWS Mainframe Modernization ofrece una serie de tipos de instancias que podemos utilizar dependiendo del tipo de la carga de trabajo o aplicación que vayamos a procesar en el motor de ejecución. Para esta demo utilizaremos la más pequeña que es la instancia M2.m5.large.
Por último pasamos a la sección de seguridad y redes donde seleccionamos la VPC, las subredes y grupos de seguridad que queremos utilizar para desplegar estas instancias. Para este demo seleccionamos la opción “Permitir que las aplicaciones implementadas en este entorno sean accesibles públicamente”, esta opción asigna una dirección IP pública a la aplicación para que se pueda acceder a ella desde un navegador web.
El siguiente paso es seleccionar el almacenamiento, en caso de que nuestra aplicación de mainframe requiera de un almacenamiento como EFS o FSx podemos configurarlo en esta opción. Para esta demo no será necesario estos tipos de almacenamiento.
Ahora pasamos a la programación del mantenimiento, como AWS Mainframe Modernization es un servicio gestionado, AWS se encarga de realizar el mantenimiento y aplicar las actualizaciones, sin embargo debemos seleccionar cuando se deben programar estas ventanas de mantenimiento para no afectar el funcionamiento de las aplicaciones de mainframe que ya se encuentran desplegadas. Para esta demo seleccionaremos la opción de no preferencia.
Ya para finalizar la creación de nuestro entorno de ejecución, se muestra un resumen de la configuración seleccionada para hacer un último chequeo antes de crear el entorno. En esta demo la creación del entorno de ejecución tardo aproximadamente entre 4 y 5 minutos.
- **<u>Paso 4 – Creación de la aplicación de mainframe</u>**
En este paso lo que hacemos es configurar la aplicación de mainframe que queremos desplegar.
El paso 1 de esta sección es la especificación de la información básica, donde damos un nombre a nuestra aplicación, una descripción y seleccionamos el tipo de motor que en este caso es Blu Age.
Adicionalmente se ofrecen otras opciones de configuración como lo es adicionar un llave de KMS, adicionar un rol de IAM y tags para asignar a estos recursos.
El paso 2 de esta sección hace referencia a la especificación de recursos y configuraciones, este paso es clave configurarlo adecuadamente, porque de esta configuración dependerá en gran parte la correcta ejecución de la aplicación. Acá simplemente copiamos el código JSON que configuramos anteriormente donde definimos el bucket y la ruta donde se encuentra el archivo ZIP con la aplicación de mainframe refactorizada o simplemente seleccionamos la ruta del bucket donde se encuentra este archivo JSON.
El último paso de esta sección es la revisión y la creación de la configuración de la aplicación de mainframe. Para esta demo este proceso tardo aproximadamente 30 segundos.
- **<u>Paso 5 – Desplegar la aplicación mainframe</u>**
Ya habiendo creado el entorno de ejecución y la configuración de la aplicación, únicamente nos haría falta desplegar la aplicación refactorizada con Blue Age en este entorno de ejecución que hemos creado y configurado.
Para acceder a la configuración de despliegue simplemente damos click en el nombre de la configuración de aplicación que acabamos de definir para este demo “app_planetsdemo” y damos click en el botón Deploy.
En este paso lo único que hacemos es seleccionar la versión de nuestra aplicación de mainframe y el entorno de ejecución donde queremos desplegarlo.
Para esta demo este proceso tardo en desplegar la aplicación aproximadamente 15 min.
- **<u>Paso 6 – Ejecutar y probar la aplicación</u>**
Después de haber realizado todos estos pasos y su respectiva configuración, procedemos a ejecutar y probar la aplicación de ejemplo de AWS Planets Demo. Vamos a notar algo interesante y es que al haberse realizado la refactorización de la aplicación de mainframe, modernizando el código de COBOL a JAVA, ingresaremos a la aplicación en modo web por medio de un navegador. Pero antes de ejecutar la aplicación en vivo, debemos iniciarla y una vez iniciada vamos a la sección de información de la aplicación, donde podemos observar que se configuro y se asigno un DNS Hostname que es la dirección que debemos ingresar en el navegador web.
> _[Ver GIF Animado](https://wiki-cloud.co/wp-content/uploads/2024/07/article_image_aws_deploy_refactored_mainframe_applications_23.gif)_
Para muchos esta aplicación les recordara épocas del pasado pero que ahora son una realidad tenerlas en la nube de AWS y en su servicio de AWS Mainframe Modernization. Esta aplicación es muy sencilla simplemente digitamos un nombre de un planeta del sistema solar e inmediatamente nos trae información sobre el planeta que hemos buscado. Como la aplicación se ejecuta en un ambiente web podemos cambiar la apariencia de la pantalla.
En el navegador ingresamos la siguiente URL: http://{DNS hostname}:{port}/PlanetsDemo-web-1.0.0/
Ahora vamos a la acción !!
> _[Ver GIF Animado](https://wiki-cloud.co/wp-content/uploads/2024/07/article_image_aws_deploy_refactored_mainframe_applications_24.gif)_
- **<u>Paso 7 – Monitoreo aplicación mainframe</u>**
Dentro de la sección de aplicación, aparecen varias pestañas con determinada información y una de ellas es la de monitoreo, cuando ingresamos a esta, se muestran diferentes graficas con métricas que miden el performance de la infraestructura y de la aplicación mainframe.
> _[Ver GIF Animado](https://wiki-cloud.co/wp-content/uploads/2024/07/article_image_aws_deploy_refactored_mainframe_applications_25.gif)_

- Professional : Today was not the most productive. Started off with responding to some community questions. Chatted with a team member about a project were working on. During my lunch break, I came across some pretty dope properties that just went on the market and spent quite a bit of time researching and reaching out to the realtors. Got to open the door when opportunity knocks. I may be taking a trip to Georgia again to check out some land. The day was pretty much over by the time I got back, but I did get a little more work done on the refactor project. I'll probably work on it some during the weekend.
- Personal : Last night, I picked up some projects on Bandcamp and got the social media posts ready. Also went through some tracks for the radio show. Looked at some properties. Did some research on my side project. Trying to figure out how to get this functionality working. I think it will be similar to a Web Component I made. It's about combining multiple canvases. Ended the night watching the latest episode of "The Boys". That show is wild!
I'll finish putting together the playlist for the radio show tomorrow. Going to see if I can get a proof of concept for my side project working. I may hop back on to the project I'm refactoring for work. Looking to end the night watch an episode of "The Suicide" anime. Saturdays, check the radio show at https://kNOwBETTERHIPHOP.com and Sundays for the study sessions at https://untilit.works
Have a great night and weekend!

1. When I open lazygit with the `LazyGit` command, it does not open at the current file in my buffer I opened from
2. When I want to edit a file highlighted in lazygit, I cannot do it in the window I opened lazy git from, only in the current floating pane
This can be improved!
First, I added a new keymap to my nvim config to launch lazygit and then do a search for the filename from the current buffer
``` lua
vim.keymap.set("n", "<leader>lg", function()
-- get file name with extension
local file = vim.fn.expand("%:t")
vim.cmd("LazyGit")
-- Wait a bit for LazyGit to load
vim.defer_fn(function()
-- search for the file, highlight, and exit search mode in lazygit
vim.api.nvim_feedkeys("/" .. file, "t", true)
vim.api.nvim_input("<CR>")
vim.api.nvim_input("<ESC>")
end, 150) -- (milliseconds)
end, { desc = "[g]it" })
```
And then in my lazygit config, I used `nvr` (neovim remote) to launch when hitting `e` to edit the file
``` config
os:
editPreset: 'nvim'
# Using -l here to change to the previous window via ":wincmd p".
edit: "nvr -l --remote {{filename}}"
```

1,921,768 | It's 2024 so why not setup Neovim (w/ NvChad) for Haskell | Introduction Recently, I've been spending time on a persistent penboot installation of... | 0 | 2024-07-13T03:07:51 | https://dev.to/bkataru/its-2024-so-why-not-setup-neovim-w-nvchad-for-haskell-2kj8 | neovim, haskell, functional, nvchad | ## Introduction
Recently, I've been spending time on a persistent penboot installation of Fedora Workstation on a 32 GB SanDisk drive.
I've avoided installing any GUI text/code editors such as VSCode (my defacto choice) or Sublime Text, and decided to stick to a basic terminal-and-vim based workflow keeping in mind the limited storage space I have to operate with.
I wanted to divide my usage between the two most popular vim editors out there by
- Using Vim for learning from tutorials, blogs, and basic books
- Using Neovim for projects and advanced books
Why? Vim's lack of features means it's more or less just a text editor with syntax highlighting. This makes writing code tedious, but tends to sharpen my command of what I'm learning. Whenever I find myself going back to basics (learning a language/framework/toolchain, following a book on some fundamentals), the minimalism of Vim has me paying more attention to what I'm typing onto the screen and be more careful of what I'm doing since I don't have a linter/LSP to catch me from falling if I make a mistake. Needless to say, I didn't configure my vim installation even a little as a result.
But when I'm working on projects or going through advanced stage books, I prefer to bring along my entire belt of gadgets - lsps, linters, formatters, debuggers in order to maximize my DX and developer velocity, in order to focus more on what I'm learning conceptually and offload the menial and tedious to as much tooling as I can. Neovim's rich and modern featureset and extensibility with its Lua-based plugin system makes it perfect for this task, while also allowing me to use my familiar _vim motions_ to move about.
---
I've been playing with Neovim and trying to configure it for Haskell. I just started going through [Learn Physics with Functional Programming - A Hands-on Guide to Exploring Physics with Haskell
by _Scott N. Walck_](https://nostarch.com/learn-physics-functional-programming) so I figured this was the perfect opportunity to figure out how well Neovim and Haskell play together. After much surfing of the world wide web, I couldn't find a straightforward, up-to-date guide to setup Neovim for Haskell in 2024, so I decided I'd make one myself and document the process along the way.
## Install GHCup
If you're new to Haskell, the de-facto toolchain is based around:
1. GHC - Glasgow Haskell Compiler, the go-to standard compiler
2. Cabal - Haskell build system
3. Stack - Similar to and sometimes an alternative of Cabal
4. HLS - The Haskell Language Server, Haskell's implementation of the Language Server Protocol for IDEs/code editors speak the Language Server Protocol (such as Neovim).
This stack is managed coherently by GHCup, the de-facto toolchain manager for Haskell.
If you don't have GHCup installed on your system, first follow their well elucidated [installation guide](https://www.haskell.org/ghcup/install/) since you'll need to ensure some system dependencies are available for GHCup to operate correctly.
Since I'm on Fedora Workstation, I'll use `dnf` to install the system dependencies listed in [System Requirements](https://www.haskell.org/ghcup/install/#system-requirements) that are specific to my OS and architecture.
```bash
$ sudo dnf update -y
$ sudo dnf install -y gcc gcc-c++ gmp gmp-devel make ncurses ncurses-compat-libs xz perl
```
Next, run GHCup's installation script for your platform as given in [How to install](https://www.haskell.org/ghcup/install/#how-to-install). I'll run the Linux one in bash using curl
```bash
$ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
```
Next, make sure to choose all defaults, which will
- Install all _recommended_ versions of the toolchain components and set them as _defaults_. Read [Which versions get installed?](https://www.haskell.org/ghcup/install/#how-to-install) to understand the options and differences.
- NOT install HLS (Haskell Language Server), since we will be installing it separately using Mason via NvChad, which uses GHCup underneath the hood to install HLS anyway.
- Setup Stack to play well with GHCup's GHC version.
After installation, GHCup and the _defaults_ will be placed in PATH and available to further shell sessions. Either restart your current shell session or type the following in Bash to source the changes into your current shell
```bash
$ . $HOME/.ghcup/env
```
You can open `ghcup tui` to make sure that all the recommended versions are installed and set as defaults
> Note that,
> - :white_check_mark: means installed
> - :white_check_mark: :white_check_mark: means installed and set as default
## Install Neovim
If you don't have Neovim, the quickest way to get it is via your [system package manager](https://github.com/neovim/neovim/blob/master/INSTALL.md#install-from-package)
Otherwise, alternate methods are listed on the same page, which contains the official [installation instructions](https://github.com/neovim/neovim/blob/master/INSTALL.md)
## Install NvChad
NvChad is a _very_ opinionated but _very_ convenient Neovim configuration to have you hit the road running with Neovim.
The quickest way to install NvChad is to clone a starter NvChad config and use `:MasonInstallAll` to install all necessary plugins right after, as given in [quickstart/install](https://nvchad.com/docs/quickstart/install/). Visit this guide if you have issues installing NvChad, as it does require some system dependencies to be installed and for you to have a Nerd Font installed and selected as your terminal's font.
> Remember to backup any preexisting Neovim config before you download NvChad as your Neovim config by running
`$ mv ~/.config/nvim ~/.config/nvim-old` first
## Overrides and Configs
Next, we need to use Mason to install HLS for language support and Haskell's Tree Sitter configuration for syntax highlighting support
We specify this by overriding their respective Neovim plugins
`~/.config/nvim/lua/plugins/init.lua`
```lua
return {
-- ...
-- ...
{
"williamboman/mason.nvim",
opts = {
ensure_installed = {
"haskell-language-server"
},
},
},
{
"neovim/nvim-lspconfig",
config = function()
require("nvchad.configs.lspconfig").defaults()
require "configs.lspconfig"
end,
},
{
"nvim-treesitter/nvim-treesitter",
opts = {
ensure_installed = {
"haskell"
},
},
},
}
```
and configure Neovim to talk LSP with our Haskell language server.
`~/.config/nvim/lua/configs/lspconfig.lua`
```lua
local on_attach = require("nvchad.configs.lspconfig").on_attach
local on_init = require("nvchad.configs.lspconfig").on_init
local capabilities = require("nvchad.configs.lspconfig").capabilities
local lspconfig = require "lspconfig"
-- ...
-- ...
lspconfig.hls.setup {
on_attach = on_attach,
on_init = on_init,
capabilities = capabilities,
filetypes = { 'haskell', 'lhaskell', 'cabal'},
}
```
That's it! We're done.
---
Now, open a Haskell file using `nvim`
```bash
$ nvim main.hs
```
Behold, your Neovim is now a powerful wielder of the wizardry that is Haskell and Functional Programming

1,921,774 | Why OOP is Your Old New Best Friend: The Date Distance Problem | Calculating the distance between two dates is relatively straightforward. There are multiple ways.... | 0 | 2024-07-13T17:46:41 | https://dev.to/yceruto/why-oop-is-your-old-and-new-best-friend-the-date-distance-problem-1059 | programming, oop, beginners, php | Calculating the distance between two dates is relatively straightforward. There are multiple ways. Think about it for a moment... If you like functional programming, your first thought might look like this:
```php
function date_distance(string $origin, string $destination): int
{
return strtotime($destination) - strtotime($origin);
}
```
That's it! Definition and implementation. It gets the job done! Simple, right? But hold on... _simple isn't always right!_
Trying to reuse this function feels like using someone else's toothbrush: it might seem okay in a hurry, but you're not really sure what issues it might cause.
Developers usually read just the first few lines:
```php
function date_distance(string $origin, string $destination): int
```
If that definition is self-explanatory, nobody cares about the implementation. But is it? Is the return value in seconds, milliseconds, or something else? What about the date arguments, `$origin` and `$destination`? They seem to be dates, but it's not entirely clear. Confusing, right?
Ensuring clarity on what every function does, what inputs it needs, and what it returns isn't easy. Even for you, because trust me, you'll eventually forget the details of your own code.
Wouldn't it be better to have a specific return type called `Seconds`? Absolutely! It's not just any random number, and _that distinction matters_. _We want to clearly indicate that the distance will be in `Seconds`._ Let's update the function to reflect this:
```php
function date_distance(DateTime $origin, DateTime $destination): Seconds
```
So, instead of any datetime string, we ask for a [`DateTime`](https://www.php.net/manual/en/class.datetime) object representing a valid datetime. And instead of returning just any integer, we return the number of `Seconds`.
```php
class Seconds
{
public function __construct(private int $distance) {}
// ...
}
function date_distance(DateTime $origin, DateTime $destination): Seconds
{
$distance = $destination->getTimestamp() - $origin->getTimestamp();
return new Seconds($distance);
}
```
The implementation looks a lot like the first version, with small changes. We're using objects and methods instead of [scalar](https://www.php.net/manual/en/function.is-scalar.php) values and functions! _The responsibility of parsing the datetime is handled by requiring a `DateTime` instance._ Nice! And I'm completely sure about the return type, no doubts, it's in seconds.
The `Seconds` object isn't just a data container; it includes behavior through methods. You can add methods for time unit conversions like `toMinutes()` or `toDays()`, and maybe an `asAbsolute()` method to always return a positive distance. Super!
However, there's another way to think about this solution. Read it again:
```php
function date_distance(DateTime $origin, DateTime $destination): Seconds
{
$distance = $destination->getTimestamp() - $origin->getTimestamp();
return new Seconds($distance);
}
```
Any other improvements? Let's look at the usage snippet:
```php
$seconds = date_distance($dateA, $dateB);
```
In our heads, it reads as "Compute the date distance between date A and date B in seconds," which is correct, but it could simply be "Compute the date A distance to date B in seconds." Still pondering? There's a principle that has always helped me reason about object-oriented solutions: ["_Tell, Don't Ask._"](https://martinfowler.com/bliki/TellDontAsk.html)
"Tell, Don't Ask" principle states that Object-orientation combines data with behavior (methods). Instead of requesting data from an object, we should tell the object what to do.
In this sense, we should never create a global function to solve a problem unless there is no relevant Object concept around it. So, this is what we want to achieve now:
```php
$seconds = $dateA->distanceTo($dateB);
```
The `distanceTo()` method doesn't exist in the `DateTime` class, but we can extend `DateTime` and create our own `DatePoint` class:
```php
class DatePoint extends DateTime
{
public function distanceTo(self $destination): Seconds
{
$distance = $destination->getTimestamp() - $this->getTimestamp();
return new Seconds($distance);
}
}
```
Note the `self $destination` argument and the `$this->getTimestamp()` call. This approach keeps the function relevant to the `DatePoint` object, ensuring that the calculation of the distance between two dates is neatly encapsulated within the object-oriented design.
This way, we leverage the full power of object-oriented programming by bundling data and behavior together.
As a challenge, I invite you to develop a complete solution that covers all the issues explained here, including validation constraints around the origin and destination dates.

## **PREREQUISITE**
- Working computer
- Internet connection
- Microsoft Azure account + active subscription
## **PROCEDURE**
### **CREATE A VIRTUAL NETWORK**
Open the Azure portal and type “Virtual network” in the search bar at the top. Click on “Virtual networks” under services as seen in the image below.
On the Virtual networks service webpage that loads, click on the “Create” or “Create virtual network” button as you deem fit.
You will be directed to the “Basics” page.
The first part of the “Basics” page is the “Project details” section where you are asked to select the subscription and resource group under which you want to create the virtual network.
Create a new resource group by clicking on “Create new” and entering a suitable name for the new resource group.
The next section is “Instance details” where you can input a virtual network name of choice and select a region.
Afterwards, click on “IP addresses”.
On that page, click on “Delete address space” to delete the current IPv4 address space.
Click on the “Add IPv4 address space” button.
Change the new address space to 10.1.0.0/16.
Click on “Add a subnet”
Leave everything as default and click on the “Add” button.
Click “Review + create”.
When a notification depicting Validation passed is displayed, click on the “Create” button to deploy the virtual network.
### **CREATE VIRTUAL MACHINES**
After the deployment is complete, click on the “Go to resource” button.
Click on the menu and select “Virtual machines”.
Click on the “Create” button and then click on “Azure virtual machine” on the pop-up menu.
You will be directed to the “Basics” page.
The first part of the “Basics” page is the “Project details” section.
Select your subscription and the resource group created earlier.
The next section is “Instance details” where you are to input a VM name of choice.
Under “Image”, select “Windows Server 2019 Datacenter - ×64 Gen2”.
Scrolling down, we get to “Administrator account” section where you are required to provide a username and password.
This will be used to log in to the account so, keep a record or use a password you won’t forget.
At the “Inbound port rules” section, select “Allow selected ports” under “Public inbound ports” and select “RDP (3389)” from the drop-down list provided when you click on the box for “Select inbound ports”.
Since this is just a trial, we would be leaving most of the settings as default and skip to only those that need to be attended to personally.
Scroll back to the top and click on “Networking”.
Make sure that the VM is placed on the previously created vNet and subnet.
Click on “Review + create.
After successful validation, click on the “Create” button. There will be a pop-up at the top right showing the status of the deployment.
You will be directed to a “CreateVm” page which goes through several phases that you might need to be patient for.
After successful deployment, repeat the process to create a second VM with a different name and public IP address.
### **TEST CONNECTION**
Open the first VM.
On the resource page, click on “Connect”.
Click on the “Download RDP file”.
Load the downloaded file and click on “Connect” on the window that pops up.
Input your username and password in the next window and affirm.
You should have a Windows VM running on your computer right about now.
Click on the start menu and type “Firewall” in the search bar.
Open “Windows Defender Firewall”.
Click on “Turn Windows Defender Firewall on or off”.
Turn off Windows Defender Firewall under both private and public network settings.
Click “OK”.
Repeat these steps for the second VM.
Head back to the first VM.
Click on the start menu and type “PowerShell” in the search bar.
Open “Windows PowerShell”.
Type in a command in this format:
`ping nameofsecondvm`. That is, “`ping vMdemo2`” in this case.
As can be seen, the second VM was successfully pinged from the first VM indicating a connection between them.

How many times did you:
- **🧑🎨 As a `DEV`** : to explain a third party how to use a job/task you have developed and delivered in your favorite language on a specific server...**happily & proudly delivered with a wiki page** that explains step by step how to run the task
- **🤔 As an `OPS`** : to discover a long documentation or issue that explains you the 100 steps to achieve to successfully run the task, schedule, monitor and integrate it with the crowd of other jobs you already have to RUN... and what to do and who to call if it fails
- **☎️ As a `hotliner`** : being frustrated to wait for the `OPS` to give you the **`root` access to this damn server so you can reboot a specific service or run `shell` script... and then complaining about their lack of trust.**
**👉 Well, `OaaS` is a way to achieve this : build an end-to-end pipeline so people, within a shared pipeline, can build, share, run, delegate and monitor job executions within an interoperable way.**
Interoperability & uniformity are the key point here, for example to :
- **Deliver** a clickable button on a web console
- **Configure** a ticket generation in some cases
- **Trigger** a third-party SaaS or non-SaaS webhook
- **Plug-it** into Pagerduty like services in case of failure
- **Let AI agents** call jobs to overcome some incident
- ...
[Rundeck](https://www.rundeck.com/) is a way to achieve this, ie. **to prioritize development/configuration/uniformity** over endless heterogeneous documentations.

1,921,789 | ShopEase | This is a submission for the Wix Studio Challenge . What I Built I built a fully... | 0 | 2024-07-13T00:20:22 | https://dev.to/sweta_kangurisonulkar_/shopease-21ii | devchallenge, wixstudiochallenge, webdev, javascript | *This is a submission for the [Wix Studio Challenge ](https://dev.to/challenges/wix).*
## What I Built
I built a fully functional e-commerce website called ShopEase using Wix Studio. ShopEase focuses on promoting and selling eco-friendly products, specifically reusable bags. The website features a dynamic homepage with sections for featured products, promotional banners, and seamless navigation.
## Demo
https://swetakanguri.wixsite.com/shopease
## Development Journey
Leveraging Wix Studio’s JavaScript Development Capabilities
I utilized Wix Studio's powerful JavaScript capabilities to enhance the functionality and interactivity of the ShopEase website:
Custom JavaScript Functions: Implemented custom JavaScript to add interactive elements such as hover effects and dynamic content updates.
javascript
Hover Effects for Banner Text:
javascript
Copy code
// Change banner text on hover
$w.onReady(function () {
$w("#bannerText").onMouseIn(() => {
$w("#bannerText").text = "Don't Miss Out - Limited Time Offer!";
});
$w("#bannerText").onMouseOut(() => {
$w("#bannerText").text = "Summer Sale - Up to 50% Off";
});
});
This script changes the text of #bannerText when a user hovers over it, providing dynamic content based on user interaction.
Dynamic Product Listing:
javascript
Copy code
// Fetch and display product data dynamically
import wixData from 'wix-data';
$w.onReady(function () {
wixData.query("Products")
.find()
.then((results) => {
let items = results.items;
items.forEach((product) => {
// Display product details on the page
$w("#productList").append(`<div>${product.name} - $${product.price}</div>`);
});
})
.catch((error) => {
console.log("Error fetching products: ", error);
});
});
This script fetches product data from a collection named "Products" and dynamically displays each product's name and price on the website.
Navigation Menu Activation:
javascript
// Activate navigation menu item based on current page
$w.onReady(function () {
let currentPage = window.location.pathname;
$w("#navMenu").forEach((menuItem) => {
if (menuItem.link === currentPage) {
menuItem.activate();
}
});
});
This script activates the navigation menu item that corresponds to the current page URL, providing visual feedback to users about their current location on the site.
// Example: Change banner text on hover
$w.onReady(function () {
$w("#bannerText").onMouseIn(() => {
$w("#bannerText").text = "Don't Miss Out - Limited Time Offer!";
});
$w("#bannerText").onMouseOut(() => {
$w("#bannerText").text = "Summer Sale - Up to 50% Off";
});
});
## APIs and Libraries Utilized
Wix Velo (Corvid): Leveraged for custom JavaScript development, enabling advanced interactions and data handling.
Wix Editor: Used for visual customization and layout design.
Wix Stores API: Integrated to manage product data and display information on the website
import wixStoresBackend from 'wix-stores-backend';
// Example function to fetch products from Wix Stores API
async function fetchProducts() {
try {
// Query products using Wix Stores API
const products = await wixStoresBackend.products.query()
.limit(10) // Limit the number of products returned
.find();
// Process the products data
products.items.forEach(product => {
console.log(`Product Name: ${product.name}, Price: ${product.price}`);
// Further processing or display logic can be added here
});
return products.items; // Return the products array if needed
} catch (error) {
console.error('Error fetching products:', error);
throw error; // Handle or rethrow the error as needed
}
}
// Example usage
fetchProducts()
.then(products => {
// Handle products data as needed
console.log('Fetched products:', products);
})
.catch(error => {
// Handle errors
console.error('Error fetching products:', error);
});

1,921,793 | Mastering Python's itertools Module | Introduction Python is a versatile programming language recognized for its easy-to-read... | 0 | 2024-07-13T00:33:55 | https://dev.to/kartikmehta8/mastering-pythons-itertools-module-4h7m | javascript, beginners, programming, tutorial | ## Introduction
Python is a versatile programming language recognized for its easy-to-read syntax and powerful functionalities. One of the most useful modules in Python is the "itertools" module, which provides a set of tools for efficient iteration and combination of elements. It is a standard library module that contains various functions for generating and manipulating iterators, which are objects used to iterate over data structures. In this article, we will explore the advantages, disadvantages, and features of mastering Python's itertools module.
## Advantages
The itertools module in Python offers numerous advantages. Firstly, it provides efficient functions for working with iterators, reducing the need for manual iteration over data structures. This makes code more concise and readable. Secondly, itertools includes functions for generating infinite iterators, which can be useful for tasks such as generating prime numbers or permutations. Furthermore, it provides tools for working with large amounts of data without the need for storing them in memory, making it memory efficient.
## Disadvantages
Although itertools is a powerful tool, it also has some limitations. One of the main drawbacks is that it only works with iterable objects, which may limit its applicability in some cases. Another disadvantage is that it does not support parallel processing, making it difficult to take advantage of multiple processors when dealing with complex calculations.
## Features
The itertools module includes a wide range of features that make it a valuable asset for developers. Some of these features include functions for iterating over combinations, permutations, and combinations with replacement. It also offers tools for grouping data, flattening nested data structures, and filtering elements based on specific criteria.
### Example of itertools usage
```python
import itertools
# Example: Generating permutations
perms = itertools.permutations([1, 2, 3])
for perm in perms:
print(perm)
# Example: Grouping data using groupby
data = [('fruit', 'apple'), ('fruit', 'banana'), ('vegetable', 'carrot')]
for key, group in itertools.groupby(data, lambda x: x[0]):
print(key, list(group))
```
## Conclusion
In conclusion, the itertools module in Python is a powerful tool for efficient iteration and combination of elements. Its advantages of improving code readability, providing infinite iterators, and being memory efficient make it a popular choice among developers. However, it also has some limitations and lacks support for parallel processing. Therefore, mastering the itertools module is beneficial, but it is important to understand its limitations and use it accordingly in your code. | kartikmehta8 |

The challenge
Your challenge is to build out this contact form and get it looking as close to the design as possible. Pay particular attention to making this form accessible. Building accessible forms is a key skill for front-end developers. So this is a perfect challenge to practice.
You can use any tools you like to help you complete the challenge. So if you've got something you'd like to practice, feel free to give it a go.
Your users should be able to:
Complete the form and see a success toast message upon successful submission
Receive form validation messages if:
A required field has been missed
The email address is not formatted correctly
Complete the form only using their keyboard
Have inputs, error messages, and the success message announced on their screen reader
View the optimal layout for the interface depending on their device's screen size
See hover and focus states for all interactive elements on the page
Tools used to build this website
- _HTML, CSS, and JS_
I am proficient in HTML and CSS because they are easy to learn. I used flexbox to be able to create the card and then used flex to be able to get the text and other elements in a column. I used media query to be able to make the website responsive.
Challenges I faced:
I learned how to use JS/HTML DOM elements to be able to add functionality to the website. This allowed me to be able to check if the form has any errors or doesn't match. If the user enters the correct information then a message would appear for 5s.

Create a function to merge 2 sorted linked lists. The resulting list should be a sorted list using the nodes of the 2 lists.
For this, we will use the generic linked list implementation from the previous post which can be found [here](https://dev.to/johnscode/reverse-a-linked-list-in-go-583i)
```
func mergeSortedLists(ll1 LinkedList[int], ll2 LinkedList[int]) LinkedList[int] {
result := LinkedList[int]{}
p1 := ll1.Head
p2 := ll2.Head
rp := &Node[int]{} // dummy node as result head
result.Head = rp
for p1 != nil && p2 != nil {
if p1.Data >= p2.Data {
rp.Next = p2
p2 = p2.Next
} else {
rp.Next = p1
p1 = p1.Next
}
rp = rp.Next
}
if p1 != nil {
rp.Next = p1
}
if p2 != nil {
rp.Next = p2
}
result.Head = result.Head.Next
return result
}
```
The logic is pretty easy to follow. First, we setup pointers to the heads of the 2 lists and the resulting list. Since we don't know the 'head' of the resulting list, we create a dummy node as a placeholder (we'll fix that one later). We also create a current node, rp, for the result list.
Next, we iterate over the 2 lists. We have a current node for each list. At each step, we look at which of the 2 current nodes has the smaller value and put that node on the result list. Then move the current node of that list (the one that was smaller) to the next node in the list. We also need to move the current node of the result to the next place.
Our loop logic is simply to keep doing this until we reach the end of one of the lists. At this point, we know that there are no more elements to compare for one of the lists; they are already in the result list. So, we can then simply put the remaining nodes of the other list at the end of the result, since we know they are already sorted.
How would you do this different? Can we optimize this? Let me know in the comments.
Thanks!

These coils are manufactured with a fantastic combination of welding together copper, steel and tin resulting into fine material for roof covering, walls cladding & other structural prospects. Read further to know more about how aluzinc steel coils are an excellent fit for different building requirements.
Roofing and Cladding Applications where Aluzinc Steel Coils are Better Than Others
They are well suited to a variety of roofing and cladding applications due in part to the outstanding corrosion resistance offered by Aluzinc steel coils. The natural flashability of these plant surfaces further reflects the amount to sunlight, resulting in a cool building from within and consequently cutbacks on unnecessary power by domestic technology (during hot summer days when more electricity is being used). Apart from these solutions being strong and durable, many of the corrugated galvanised iron products fabricated from them can easily be tailored to accommodate a variety shapes and sizes without sacrificing their structurally robustness or durability thus making it suitable for projects ranging in scale and design only limited by imagination.
All about Aluzinc Steel Coils: Commercial and Residential Buildings Under the Influence of Structural Advantages
Its use in the buildings has numerous structural benefits and which limits its advantage to be written down. The coils use their high strength-to-weight ratio to support heavy loads with minimal strain on the building structure. With very high fire resistance rates, they are able to maintain structural integrity even at extremely high temperatures without igniting flames/allowing fires, making this a smart choice for buildings that require the highest realism. They are also incredibly durable, which means they will last a long time without maintenance and other repairs that need to be done frequently.
Best for Harsh Environments: Aluzinc Steel Coils
With their unique combination of aluminium, zinc and silicon, Aluzinc steel coils are particularly suited to the harsh environments encountered in coastal or industrial settings owing to the unprecedented protection they offer against saltwater corrosion and even some corrugated iron chemical corrosion. In addition, they are also weather resistant so they can resist under extreme conditions of high winds and heavy rains which therefor makes them an appropriate choice for those living in areas with disasters such as hurricanes or typhoons.
Some economic advantages of Aluzinc steel coils in, building work
Its cost-effectiveness is a major boon for construction projects to use aluzinc steel coils. Their cost-effectiveness along with being strong and virtually maintenance-free triggers significant savings in the end. Further adding to cost savings is the flexibility and ease of installation which reduces costly offcuts, install times, therefore make them a very viable solution for budget-driven projects.
Using Aluzinc steel Coils as Building materials: adopting sustainability
In conclusion, thus aluzinz steel coils have establish as a energy-saving & environmental friendly light material; This means that they have a 100% capacity for being recycled and serving subsequent uses, which is related to the type of construction strategy since partitons can then be reused in successive stages. In addition, it helps in saving a lot of energy consumption (since an average industrial unit consumes electricity up to 5-10 times more than the air conditioner) and hence reduces high cost incurred towards cooling due cloud computing with such technology thus contributing indirectly toward climate control by using less amount of corrugated galvanized iron power.
Aluzinc steel coils are the ultimate choice for jobbing construction projects of all sizes and kinds. BGC manufactures some of the strongest, most durable materials available in market today making them perfect for roofs cladding and structural apps. Their affordability and user-friendliness combined with their environmentally-sustainable profile make aluzinc steel coils the top choice for any first-timer in construction. | nagay_iakajg_ddc052208a46 |

This is the first in probably many “why I made” posts which explains my reasoning for making a piece of software and diving deeper into future improvements.
Today, I’m going to focus on my most popular project, [TabbyAPI](https://github.com/theroyallab/tabbyAPI). TabbyAPI is a python based FastAPI server that allows users to interact with Large Language Models (or LLMs) using the [ExllamaV2](https://github.com/turboderp/exllamav2) library and adheres to the OpenAI API specification.
If you’re not sure what any of those words mean, you’re not in the AI space. But, that’s okay! This article is meant to explain my experiences without throwing the entire kitchen sink of AI terms at you.
### The start
Let me go back to the time of November 2023. AI was booming, companies were releasing models left and right, and the hype train seemed to have no end. It seems like I’m talking about a time period that was in ancient times, but back then, every day felt like a whole month of innovation.
In the onslaught of these new technologies, I was focused on running them with my paltry 3090ti. Yes, paltry is the correct word to use since 24GB of VRAM in a graphics card is entry level for running most AI models. At this time, running quantized versions of models was the norm. Quantization is analogous to compression which allows users to run these massive models on consumer GPUs.
The format that I’ve grown to love was exl2, a format that focused on speed, optimization, and getting as much as possible onto a graphics card. and tokens were generating at the speed of sound. So this format is great! What’s the issue?
The issue is running the model. Exl2 is part of the ExllamaV2 library, but to run a model, a user needs an API server. The only option out there was using [text-generation-webui (TGW)](https://github.com/oobabooga/text-generation-webui), a program that bundled every loader out there into a Gradio webui. [Gradio](https://gradio.app) is a common “building-block” UI framework for python development and is often used for AI applications. This setup was good for a while, until it wasn’t.
Essentially, the main reason for creating Tabby was annoyance. I got tired at the amount of work involved to load one model. Not to mention the overhead from Gradio and the sheer amount of dependencies from TGW. I respect the developer, but while TGW is good for many people who want an all-in-one solution, it was not good for me.
### The plan…
_Photo by Glenn Carstens-Peters on Unsplash_
is simple. Create an API server that can sit on my computer and doesn’t require a ton of bloat to run. That sounds easy, but could I actually do it? I don’t have much experience in AI model theory, but I have a lot of experience creating backend servers and understanding API design.
Therefore, I needed someone to help, but who? Enter turboderp, the person behind ExllamaV2. He pretty much knows everything behind how models work since he made the library, which is a great pairing to my API knowledge. In addition, another interested person named Splice joined due to his experience with Python. Together, the three of us started TabbyAPI.
But was the plan really that simple? Well, kind of. While I had the people for the job, my knowledge in Python and API servers was basically 0. I ended up using a webserver framework called [FastAPI](https://fastapi.tiangolo.com) which made my life much easier. It’s also very popular in the python community and well documented.
After using FastAPI for a few days, I was hooked on writing python webserver code. The documentation is very good, there are many examples online, and the developers are receptive to feedback. Overall, the community is welcoming and I’d love to use python for networking more often.
After a few weeks, I felt that everything was ready for a public deploy and decided to release everything in the best way I know. YOLO and push everything to GitHub.
### Issues and more issues
When releasing an open source project to the world, expect issues… A _lot_ of issues. People always have use cases that the utility does not fit into. Since Tabby is a backend server, many of those cases popped up. For this post, I’ll only mention a few things that were difficult for me to deal with at first.
A large pain point was that I released Tabby in the middle of the RAG hype cycle. RAG stands for “Retrieval Augmented Generation”, or using external documents in addition to the LLM’s knowledge when getting a response. The problem was that these new techniques (such as function calling) need completely different API endpoints and ways to accomplish tasks.
On top of that, there is little to no documentation on how these features actually work on the backend. To this day, I haven’t implemented OpenAI’s tool calling since I have no idea how it works. The lack of documentation is sadly common in the AI world and it stifles the ability for developers to implement code in their projects without a lot of information gathering beforehand.
Another issue that lasted for several months was multi-user generation. It turns out that handling distributed queries on a server isn’t an easy topic for a developer to work with. FastAPI provides support for this type of workload, but Tabby was written with synchronous code. This meant that I had to learn asynchronous programming in Python (which is not easy by a long shot).
The worst part is that AI developers do not like asynchronous python while networking servers embrace it. What this means is that I had to learn how to communicate between asynchronous and synchronous libraries in the form of threading. This is an even deeper dive into understanding Python’s threading issues and why the asynchronous model exists in the first place. I’ll go over all of this in another blogpost, but hopefully this explains the amount of learning that I had to do in the span of 2–3 months while battling these issues.
Eventually, turbo and I worked together to create a better generator in the ExllamaV2 library which stripped away all multi-user woes and weird bugs from threading libraries. After 9 months, it’s safe to say that Tabby is finally a stable program to run models with.
### Burnout
_Photo by Annie Spratt on Unsplash_
During my entire time of developing software, I’ve never had a burnout period. That’s hard to believe since burnout is a common thing within the software world, but I’ve always wanted to code something for the past 6 years. Coding is my favorite pastime and helps me escape the stresses of the day.
However, Tabby and the AI community in general changed things. At the start, I made a lot of friends and people who shared common interests in exploring the booming field of AI. My community used to engage in voice calls pretty much every day and focused on sharing projects and ideas about what’s new in the space. It made development fun and enjoyable since I got to hang out with like-minded people and share new ideas.
Unfortunately, those voice calls started having less people and happened less often. I was also under a lot of stress due to finishing up my first year of medical school. In the online world, this was a huge period of loneliness for me and developing Tabby felt like a burden on top of my med student life. Eventually, these events culminated in a large ball of frustration and tiredness. To solve it, I decided to take an indefinite break from AI.
During my break, I spent time away from Tabby and spent more time enjoying my summer vacation. I actually worked on some older iOS app projects and spent time with my family. Nowadays, I’m getting back into developing Tabby again. Those voice calls I used to partake in probably won’t happen for a long while due to the fading of AI hype. It’s a tough pill to swallow, but I’ve found different motivations for continuing development.
### Lessons I learned
Tabby was the first LLM project I’ve ever made. It somehow became a popular name within the community and I was thrown into the deep end of management. Knowing that, here’s a few thoughts that I learned from this experience.
Know who you want to cater to: Anyone can use an open source project. For Tabby, I prioritize features that will benefit the project’s ease of use, my friends, and myself. By keeping this philosophy in check, I can manage my schedule and I’ll know what features to work on.
Understand your limits: Burnout isn’t fun. Don’t do what I did and run yourself down because a user has an issue for the umpteenth time. If the feelings of frustration, anger, or boredom ever show up, take a break. It’s good to relax once in a while.
Don’t bend over backwards for everyone: An idea may look good when it’s first presented, but people don’t understand that the developer needs to maintain this feature afterwards. If it’s a pain and not used much, the feature isn’t going to be maintained and will become tech debt. Remember that random strangers on the internet always have ideas. It’s up to you or your team to decide which ones to commit brainpower to.
Create something you love and enjoy: Developers often lose enjoyment on a project because maintaining can be troublesome and take a long time. This is especially true if the developer no longer actively uses the project. Figure out what your motivation is, and if it changes, that’s okay.
I’ll probably elaborate on these in another article since this can be its own topic, but I feel that working on Tabby has given me more insights to how I want my projects to work. In addition, my knowledge of the open source community has been expanded.
### What the future holds
I’m thankful to all the people that contribute and give suggestions daily to improve both TabbyAPI and ExllamaV2. Everyone helps refine and improve the programs to work better for general use. I’m one person and helping out takes a lot off of my plate.
For the foreseeable future, I’m going to cut back on how much I’m working on Tabby. The project is still going strong and many are committing to improving it, but my mental health is more important and taking breaks will help with that.

Hoje se ouve muito falar em Inteligência Artificial (IA), como ela esta melhorando o nosso dia a dia.
Muitas empresas estão automatizando processos e economizando muito dinheiro com a construção de agentes de IA, tudo isso é possível por conta do Modelos de IA.
Mas você saberia me dizer o que seria um Agente de IA? ou o que seria um Modelo de IA?
Caso a sua resposta seja não, você esta no lugar certo, neste artigo vamos explorar esses conceitos para que você tenha na ponta da lingua estas respostas.
Começando pelos modelos de IA, eles são algoritmos e arquiteturas computacionais que permitem que sistemas de Inteligência Artificial aprendam a partir de dados e realizem tarefas específicas.
Esses modelos são treinados com grandes conjuntos de dados e ajustados para melhorar seu desempenho ao longo do tempo.
Para ficar mais claro, imagine um modelo de IA como um desenvolvedor aprendendo uma nova tecnologia ou linguagem de programação. Ele lê documentação, tutoriais, exemplos de código e fóruns. Ao assimilar essa vasta quantidade de informações, o desenvolvedor começa a identificar padrões e relações entre diferentes conceitos, ferramentas e práticas.
Voltando ao modelo, conforme ele é exposto a mais exemplos e recebe feedbacks sobre seu desempenho, ele ajusta seus parâmetros internos para melhorar sua precisão e eficiência.
Existem muitos modelos, a seguir estou listando alguns dos que eu mais utilizei:
* GPT-4: é um exemplo de um modelo de linguagem grande (LLM), que foi treinado em bilhões de textos para gerar respostas coerentes e contextualmente relevantes para uma ampla gama de perguntas.
* YOLO (You Only Look Once): Um modelo usado para detecção de objetos em tempo real. Ele é capaz de detectar múltiplos objetos em uma imagem com alta velocidade e precisão.
* O Mistral 7B: é um modelo de linguagem de grande (LLM) desenvolvido por Mistral AI. Ele é um exemplo de um modelo de linguagem pré-treinado, projetado para processar e gerar texto natural de alta qualidade.
Mas qual seria a função de um modelo de IA?
A função de um modelo de IA é transformar dados de entrada em uma saída útil, realizando tarefas específicas de acordo com o tipo e objetivo do modelo.
Pensando nos modelos que nós vimos acima, a seguir você tem alguns exemplos de como eles desempenham suas funções:
* GPT-4: pode ser utilizado para gerar texto em linguagem natural, responder a perguntas ou até mesmo escrever artigos completos;
* Mistral 7B: pode ser usado para prever tendências de vendas com base em dados históricos;
* YOLO: pode ser usado em sistemas de segurança para detectar a presença de pessoas e objetos em imagens de câmeras de vigilância.
Agora que sabemos o que é um modelo de IA e vimos algumas possibilidades de utilização deles, vejamos o que seria um Agente de IA.
Um Agente de IA é um programa de software que pode interagir com seu ambiente, coletar dados e usar os dados para realizar tarefas autodeterminadas para atingir metas predeterminadas.
Enquanto um modelo de IA é essencialmente uma ferramenta que processa dados e gera resultados, um agente de IA é uma aplicação mais abrangente que integra esses modelos para interagir de forma inteligente com o ambiente.
Exemplos de Agentes de IA:
* Assistentes virtuais;
* Veículos autônomos;
* Agentes de suporte ao cliente;
Bom, acredito que agora você saiba responder as perguntas iniciais deste artigo :)
Espero que tenham gostado e até a próximo pessoal :)

1,921,830 | [Book Review] Beej's Guide to Network Programming | Intro - what is this book about? Yes, I finally finished reading this book. As a person... | 0 | 2024-07-13T01:38:11 | https://dev.to/uponthesky/book-review-beejs-guide-to-network-programming-9mg | computerscience, socket, c | ## Intro - what is this book about?
Yes, I finally finished reading this book.
As a person who has never taken a computer networking course in university, I had thought for a long time of learning that subject intensively. However, I could not find a solid university course that is open to public(something like [MIT’s introduction to algorithms](https://ocw.mit.edu/courses/6-006-introduction-to-algorithms-spring-2020/)). And many of the textbooks prefixed “introduction” spent hundreds of pages explaining quite low-level concepts such as routing algorithms or even physical wires that connect the continents!
Then I found [Beej's Guide to Network Programming](https://beej.us/guide/bgnet/) that is recommended frequently on the Internet. At a glance, I found it easy to read because of the author’s way of explaining concepts in a humorous manner. But at the same time, compared to other computer network books, this book contains many code examples, so that I thought it suits more for the programmers who want practical socket programming practice.
And after reading through all the chapters except chapter 9(because it is more like a reference for a bunch of C socket functions), I found it a good read.
## Good parts
### Friendly introduction to technical concepts
The book starts with a few basic concepts such as IP, port, and socket. However, it doesn’t go deeper into introducing very technical algorithms or physical devices used for network communications. As a developer who deals with web applications daily, I found it more relevant to my job. Even though the book sometimes mentions bits and bytes, it is still readable and you usually never do any bitwise operations while reading the C code in the book.
### Plenty of code examples
For those who want to get their hands dirty with code, this book is for you. Except for the general overview parts on computer networking, most of the explanations in the book come with code examples in C. This is particularly useful for knowing how actual network communications occur inside our web applications. For example, the [polling operation](https://beej.us/guide/bgnet/html/split/slightly-advanced-techniques.html#poll) sweeps through all the registered sockets to check whether there are incoming events to be handled.
Moreover, the examples don’t import any external libraries, so you don’t have to deal with irritating third-party dependency problems.
## Soso parts
### Mainly focused on socket programming only
This book is very good as a friendly reference to socket programming and relevant system calls. However, it does not go “higher” or “lower”:
- "higher": Most of today’s web applications rely on the HTTP protocol. It could have been better if the book contained more explanations on this higher layer with actual running code.
- "lower": I think the book could have shown how a packet looks like using tools such as Wireshark that snatches packets generated by the examples. Introducing a few Linux/Unix commands for networking could also have been helpful for understanding how our application code interacts with the kernel.
However, I found another good resource written by the same author: [Beej's Guide to Networking Concepts](https://beej.us/guide/bgnet0/). It seems to cover many core concepts more comprehensively than this book with a lot of coding exercises. I hope this “concept” book will fill the gap of the “programming” book.
### Not recommended for those who are not familiar with C code
If you don’t know much about C programming, this book could be overwhelming. It doesn’t explain any basic concepts such as pointers or type casting. Although we don’t suffer from dependency hell like when dealing with CMake, if you don’t know much about C then reading code would still be difficult.
Personally I am okay with C code. However, the book could have been more beginner-friendly if it were written in Python, which has almost all the counterparts of the socket functions of C in its [socket library](https://docs.python.org/3/library/socket.html). The ["concept" book](https://beej.us/guide/bgnet0/) by the same author uses Python this time, so we can expect some fun there.
## Conclusion
Overall, the book is filled with practical code examples that are useful when understanding a network application using socket system calls. Of course, you won’t really need to use these functions when writing your own application, because many languages support their own wrappers for those "low-level" socket networking functions(Python has libraries like [socketserver](https://docs.python.org/3/library/socketserver.html) and [http](https://docs.python.org/3/library/http.html)). Nonetheless, I think once in your career as a developer you should understand what is going on behind all these highly abstracted communications using HTTPS or websocket. In that sense, this book is a good read and also a good reference. | uponthesky |

Gaya Hidup dan Diet: Kekurangan serat dalam makanan, kurangnya aktiviti fizikal, dan kebiasaan duduk terlalu lama.
**Jenis Buasir**
Terdapat dua jenis utama buasir:
Buasir Dalaman: Terletak di dalam rektum dan biasanya tidak dapat dilihat atau dirasai kecuali apabila ia prolaps (keluar melalui dubur).
Buasir Luaran: Terletak di luar dubur dan boleh terasa sebagai benjolan yang lembut.
**Gejala Buasir**
Gejala buasir bergantung kepada jenis dan tahap keparahannya. Gejala yang biasa termasuk:
Rasa gatal atau terbakar di sekitar dubur.
Rasa tidak selesa atau sakit semasa duduk.
Perdarahan semasa atau selepas buang air besar.
Benjolan atau pembengkakan di sekitar dubur.
Rawatan dan Pencegahan
Rawatan bergantung kepada tahap dan keparahan buasir:
Pengubatan Konservatif: Termasuk penggunaan krim atau salep, dan mengubah gaya hidup untuk mengelakkan sembelit.
Prosedur Minimally Invasive: Seperti pengikatan kawat atau skleroterapi untuk buasir yang teruk.
Pembedahan: Kadang-kadang diperlukan untuk buasir yang sangat teruk atau kronik
**Pencegahan Buasir**
Langkah-langkah berikut boleh membantu mengurangkan risiko atau mencegah kekambuhan buasir:
Makan makanan kaya serat untuk mengelakkan sembelit.
Minum banyak air untuk menjaga konsistensi najis.
Berolahraga secara teratur.

1,921,833 | Optimizing Performance in React Applications | As a React developer, ensuring that your applications run smoothly and efficiently is crucial for... | 0 | 2024-07-13T01:41:22 | https://dev.to/khalidkhankakar/optimizing-performance-in-react-applications-59k0 | webdev, react, performance, javascript | As a React developer, ensuring that your applications run smoothly and efficiently is crucial for providing a great user experience. Performance optimization can make the difference between a fast, responsive app and one that feels sluggish. In this blog post, we'll explore several techniques to optimize performance in React applications, complete with code examples and real-world scenarios.
## 1. Use React's Built-in Performance Tools
React provides built-in tools to help identify performance bottlenecks. The React Developer Tools extension for Chrome and Firefox allows you to inspect your React component tree, identify unnecessary re-renders, and analyze component performance.
Example: React Developer Tools
- Install the React Developer Tools extension from the Chrome Web Store or Firefox Add-ons.
- Open your React application and the developer tools.
- Navigate to the "Profiler" tab to start recording performance profiles.
- By analyzing the profiling data, you can pinpoint components that are causing performance issues and take steps to optimize them.
## 2. Avoid Unnecessary Re-Renders
React's reconciliation process ensures that the DOM updates efficiently, but unnecessary re-renders can still degrade performance. To prevent this, you can use React.memo and shouldComponentUpdate.
Example: Using React.memo
jsx
```
import React, { memo } from 'react';
const MyComponent = ({ data }) => {
console.log('Rendering MyComponent');
return <div>{data}</div>;
};
export default memo(MyComponent);
```
In this example, MyComponent will only re-render if the data prop changes. Using React.memo can help reduce unnecessary renders and improve performance.
## 3. Optimize Component Rendering
Sometimes, breaking down large components into smaller, reusable ones can improve performance by reducing the amount of work each render requires. Additionally, you can use techniques like code splitting and lazy loading to load only the necessary parts of your application.
Example: Code Splitting with React.lazy
jsx
```
import React, { Suspense, lazy } from 'react';
const MyComponent = lazy(() => import('./MyComponent'));
const App = () => (
<Suspense fallback={<div>Loading...</div>}>
<MyComponent />
</Suspense>
);
export default App;
```
In this example, MyComponent is loaded only when needed, reducing the initial load time of the application.
## 4. Optimize State Management
Efficient state management is crucial for performance. Use local state only when necessary, and prefer using state management libraries like Redux or Zustand for more complex state management scenarios.
Example: Using Zustand for State Management
jsx
```
import create from 'zustand';
const useStore = create((set) => ({
count: 0,
increment: () => set((state) => ({ count: state.count + 1 })),
}));
const Counter = () => {
const { count, increment } = useStore();
return (
<div>
<span>{count}</span>
<button onClick={increment}>Increment</button>
</div>
);
};
export default Counter;
```
Zustand provides a lightweight and efficient way to manage state, helping to keep your components lean and performant.
## 5. Memoize Expensive Calculations
If your components rely on expensive calculations, you can use useMemo to memoize these calculations and prevent them from being recomputed on every render.
Example: Using useMemo
jsx
```
import React, { useMemo } from 'react';
const ExpensiveComponent = ({ items }) => {
const sortedItems = useMemo(() => {
console.log('Sorting items...');
return items.sort((a, b) => a - b);
}, [items]);
return (
<ul>
{sortedItems.map((item, index) => (
<li key={index}>{item}</li>
))}
</ul>
);
};
export default ExpensiveComponent;
```
In this example, the sortedItems array is only recalculated when the items prop changes, reducing the computational overhead.
## 6. Throttle and Debounce Event Handlers
Handling frequent events like scrolling or typing can cause performance issues. Throttling and debouncing event handlers can help mitigate this.
Example: Using lodash's debounce
jsx
```
import React, { useState } from 'react';
import debounce from 'lodash.debounce';
const SearchBar = () => {
const [query, setQuery] = useState('');
const handleChange = debounce((event) => {
setQuery(event.target.value);
}, 300);
return <input type="text" onChange={handleChange} />;
};
export default SearchBar;
```
In this example, the handleChange function is debounced, meaning it will only be called 300 milliseconds after the user stops typing, reducing the number of unnecessary updates.
## 7. Optimize Images and Assets
Large images and assets can slow down your application. Use tools like react-image and react-async-script-loader to optimize images and load scripts asynchronously.
Example: Using react-image
jsx
```
import React from 'react';
import { Img } from 'react-image';
const OptimizedImage = ({ src, alt }) => (
<Img
src={src}
loader={<div>Loading...</div>}
unloader={<div>Failed to load image</div>}
alt={alt}
/>
);
export default OptimizedImage;
```
In this example, react-image helps optimize image loading by providing a loader and unloader, ensuring that your application remains responsive even with large images.
## Conclusion
Optimizing performance in React applications involves a combination of techniques, from preventing unnecessary re-renders to optimizing state management and memoizing expensive calculations. By applying these strategies, you can ensure that your React applications are fast, responsive, and provide a great user experience.
Remember, performance optimization is an ongoing process. Continuously monitor your applications using tools like the React Developer Tools and adjust your strategies as needed to maintain optimal performance. | khalidkhankakar |

1,921,839 | Propane Gensets: Powering Homes and Businesses with Clean Energy | Propane Gensets Capable Of Providing a Stable Energy Source For Homes and Businesses As we all know,... | 0 | 2024-07-13T01:52:02 | https://dev.to/nagay_iakajg_ddc052208a46/propane-gensets-powering-homes-and-businesses-with-clean-energy-46oe | design | Propane Gensets Capable Of Providing a Stable Energy Source For Homes and Businesses
As we all know, there is always a full dependence on electricity in our day to day lives. It is what allows us to light our homes, use appliances safely and run businesses smoothly. But the unexpected power outage that messes up our routines is also a nuisance. This is a time where you absolutely need the backup power supply. Natural gas gensets can keep the lights on but propane offers its own benefits which is where the much smaller capacity of a diesel generator may say uncle, and this is why propane gensets are an overlooked boon. In this article we will explore the advantages, operational mechanics and safety characteristics of propane gensets to elucidate why they have become an irreplaceable energy alternative in households as well as various commercial areas.
Benefits of Propane Generators:
Type of Fuel:-Propane gensets have a lot going for them completely unrelated to the fact that they use propane as fuel. Propane is a cleaner-burning fuel than gasoline or diesel, so the emissions profile of propane-fueled buses will be more favorable. This makes it an environmentally better option for Natural gas generator. Propane may also be stored safely for long periods, without deterioration in quality ensuring it will keep even during time of emergencies. The availability of propane is good for any location and inexpensive compared to other options, also priding itself as an affordable option when it comes backup power needs.
Propane Gensets Further Innovating
Recent advancements in propane gensets Homeowners and businesses now have a diverse selection of propane gensets to choose from based on their power needs. Today, state-of the art gensets come with tech-savvy features that make them not only more efficient but reliable. By design, a lot of propane gensets ship with autotransfer switches that allow them to start so long as the power is out. Others have wireless monitoring (which allows the generator's status to be checked from a smartphone or computer), and some are expandable.
Propane Gensets Safety:
Propane generators generally are safe gensets. Propane is not highly flammable, such as gas or diesel would be, mitigating safety risks. These tanks are typically good at withstanding high pressures and temps effectively, making them both safe and strong. Additionally, propane gensets are set up with leading-edge safety features that stop the engine when a danger is detected and do things like spark arrestors to keep them from starting fires.
Efficient Use of Propane Gensets:
Operating a Propane Generator The Simple Way The first step to installing a Natural gas and gas generator is figuring out what size you need based on how much power you want. The genset should be located at safe and close distance once if it is purchased. After that, the propane tanks have to be refilled so we have enough fuel for the generator. Periodic testing of generator before use play a very important role, as genset helps confirm that gen set is working in good condition and ready for emergency time.
Maintaining Propane Gensets:
Standard care is necessary for propene to travel into the camp once needed. Periodic servicing must be performed by fully trained mechanics to identify and correct problems or broken/missing components. Owners can simply follow a regular maintenance schedule to ensure their gensets stay in the best shape possible so they are reliable during surprise power outages.
Propane Gensets: Quality Standards And Versatility
This is another area where propane gensets vary quite a bit from lower to higher-quality units, making the selection of one that has good reviews very important. Plenty of investors right now looking out for sources which are recognized to provide the most power able generators and many others & likewise evolutionary at beneficial funding choice. Whether the Propane Genset runs continuously or just when there's a power outage, they are dependable and efficient sources of backup power.
In Conclusion:
In the end, propane gensets are simply a good choice for solid standby power. Their many benefits make them a better option as compared to other power backup sources due to cost and environmental reasons. Backed by ongoing Natural gas electric generator technological advancement, propane gensets are increasingly efficient and dependable with cutting-edge features to improve performance. The safe features guarantee the safety work, and ordinary pros servicing life span due to proper functionality.

1,921,844 | Day 10 & 11 of my Devops Journey: Kubernetes Networking Fundamentals - Challenges and Solutions | Introduction: Hey everyone! Welcome back to Day 10 & 11 of my SRE and Cloud Security journey.... | 0 | 2024-07-13T02:44:09 | https://dev.to/arbythecoder/day-10-11-of-my-devops-journey-kubernetes-networking-fundamentals-challenges-and-solutions-3c59 | devops, kubernetes, beginners, networking | **Introduction:**
Hey everyone! Welcome back to Day 10 & 11 of my SRE and Cloud Security journey. Today, we dove deep into Kubernetes networking, and let me tell you, it wasn't all sunshine and rainbows. I encountered some real head-scratchers, but with persistence and a little help from the internet, I was able to overcome them. So, let's dive into the challenges I faced and the solutions I implemented!
**Challenges:**
1. **Setting Up Minikube:** My first hurdle was getting Minikube running smoothly on my Windows machine. It felt like I was trying to fit a square peg into a round hole! I encountered errors and had to troubleshoot the installation process.
2. **Understanding the `kubeconfig` File:** I had a bit of a moment of confusion when I realized I had multiple Kubernetes clusters configured in my `kubeconfig` file. Switching between them felt like navigating a maze!
3. **Connecting to the Right Cluster:** The biggest challenge was figuring out how to connect to the correct Kubernetes cluster, especially since I had a mix of local and cloud-based clusters. It was like trying to find the right address in a city with confusing street signs.
**Solutions:**
1. **Minikube Setup:** I carefully followed the Minikube installation guide for Windows, ensuring that Hyper-V (you can use Docker Desktop) was properly enabled. I also checked the Minikube logs for any error messages and addressed them accordingly.
2. **`kubeconfig` File Management:** I learned how to use the `kubectl config` commands to list all the contexts in my `kubeconfig` file, identify the problematic ones, and delete them. I also learned to set the `current-context` to the cluster I wanted to work with.
3. **Connecting to the Correct Cluster:** I used `kubectl config use-context` to switch to the `docker-desktop` context, which was the cluster I wanted to use for my Day 10 & 11 project. I also learned to verify the server address and other details in my `kubeconfig` file to ensure it was pointing to the correct cluster.
**Conclusion:**
Day 10 & 11 was a rollercoaster ride of challenges and triumphs. I learned a lot about Kubernetes networking, the importance of managing your `kubeconfig` file, and the value of persistence in troubleshooting. I'm feeling more confident now, like I have a better understanding of the roads and traffic lights in my Kubernetes city! | arbythecoder |

1,921,856 | Object-Based UI State Management vs. JavaScript Proxy-Based UI State Management | State management is a critical aspect of modern UI development, especially as applications grow in... | 0 | 2024-07-13T02:33:56 | https://dev.to/guhandelta/object-based-ui-state-management-vs-javascript-proxy-based-ui-state-management-58bk | State management is a critical aspect of modern UI development, especially as applications grow in complexity. Two popular methods for managing UI state in JavaScript applications are object-based UI state management and proxy-based UI state management. Both approaches have their advantages and trade-offs. This article delves into these two methodologies, comparing their concepts, implementation, and practical use cases, using Redux and Zustand as examples.
**Object-Based UI State Management:**
Object-based state management involves managing the state using plain JavaScript objects. This method typically leverages libraries like Redux, MobX, or even the Context API in React. The core idea is to have a central store (an object) that holds the application’s state, and components subscribe to changes in this state.
**Key Characteristics:**
**Centralized Store:** State is stored in a single or a few central objects.
**Immutable Updates:** State updates are performed immutably. Instead of modifying the existing state, a new state object is created and replaced.
**Action-Based Changes:** State changes are triggered by dispatching actions (in libraries like Redux), which describe the changes to be made.
**Selectors:** Functions that derive specific pieces of state from the central store, allowing components to subscribe to only the data they need.
**Advantages:**
**Predictability:** Clear flow of data and state transitions make it easy to reason about the state changes.
**Debugging:** Tools like Redux DevTools provide powerful debugging capabilities, showing the state before and after each action.
**Testing:** The separation of actions and reducers (or similar constructs) facilitates easier unit testing.
Disadvantages:
**Boilerplate Code:** Often involves writing more code (actions, reducers, selectors), which can be verbose and cumbersome.
**Performance:** Frequent state updates can lead to performance bottlenecks if not managed properly, especially in large applications.
<u>Example with Redux:</u>
**Redux Code Sample
1)Installation:**
```
npm install redux react-redux
```
**2. Defining Actions:**
```
// actions.js
export const INCREMENT = 'INCREMENT';
export const DECREMENT = 'DECREMENT';
export const increment = () => ({
type: INCREMENT
});
export const decrement = () => ({
type: DECREMENT
});
```
**3. Creating Reducers:**
```
// reducers.js
import { INCREMENT, DECREMENT } from './actions';
const initialState = {
count: 0
};
const counterReducer = (state = initialState, action) => {
switch (action.type) {
case INCREMENT:
return { ...state, count: state.count + 1 };
case DECREMENT:
return { ...state, count: state.count - 1 };
default:
return state;
}
};
export default counterReducer;
```
**4. Setting Up the Store**
```
// store.js
import { createStore } from 'redux';
import counterReducer from './reducers';
const store = createStore(counterReducer);
export default store;
```
**5. Connecting React Components**
```
// App.js
import React from 'react';
import { Provider, useSelector, useDispatch } from 'react-redux';
import store from './store';
import { increment, decrement } from './actions';
const Counter = () => {
const count = useSelector(state => state.count);
const dispatch = useDispatch();
return (
<div>
<p>Count: {count}</p>
<button onClick={() => dispatch(increment())}>Increment</button>
<button onClick={() => dispatch(decrement())}>Decrement</button>
</div>
);
};
const App = () => (
<Provider store={store}>
<Counter />
</Provider>
);
export default App;
```
**Proxy-Based UI State Management**
Proxy-based state management leverages the Proxy object in JavaScript, which allows for the creation of objects with custom behavior for fundamental operations like getting and setting properties. Libraries like Vue 3 (with its Composition API and reactive system) and Immer use Proxies to achieve reactivity and immutability.
**Key Characteristics:**
**Reactive State:** State is made reactive by wrapping objects in a Proxy, which intercepts operations and triggers updates.
**Transparent Mutations:** State can be mutated directly, and the Proxy ensures that the changes are tracked and propagated.
**Minimal Boilerplate:** Direct mutations reduce the need for boilerplate code, making the development process more straightforward.
**Advantages:**
**Simplicity:** Allows for direct state mutations, reducing the need for boilerplate code.
**Reactivity:** Automatically tracks dependencies and updates, providing a responsive UI without manual subscription management.
**Performance:** Efficiently tracks and updates only the parts of the state that change.
**Disadvantages:**
**Complexity in Debugging:** Debugging can be more challenging due to the implicit nature of reactivity.
**Learning Curve:** Understanding Proxies and their behavior can be more difficult for developers unfamiliar with this concept.
**Example with Valtio Composition API:**
**1. Valtio Code Sample**
Installation
```
npm install valtio
```
**2. Creating State**
```
// state.js
import { proxy } from 'valtio';
const state = proxy({
count: 0
});
export default state;
```
**3. Creating Actions**
```
// actions.js
import state from './state';
export const increment = () => {
state.count += 1;
};
export const decrement = () => {
state.count -= 1;
};
```
**4. Connecting React Components**
```
// App.js
import React from 'react';
import { useSnapshot } from 'valtio';
import state, { increment, decrement } from './state';
const Counter = () => {
const snap = useSnapshot(state);
return (
<div>
<p>Count: {snap.count}</p>
<button onClick={increment}>Increment</button>
<button onClick={decrement}>Decrement</button>
</div>
);
};
const App = () => <Counter />;
export default App;
```
**Comparison and Use Cases**
**Predictability and Debugging:**
- Object-based state management offers better predictability and easier debugging with tools like Redux DevTools.
- Proxy-based state management can be less predictable due to the implicit reactivity, making debugging more complex.
Boilerplate and Development Speed:
- Object-based state management often requires more boilerplate code, which can slow down development.
- Proxy-based state management simplifies the code by allowing direct mutations, speeding up the development process.
**Performance:**
Both methods can be performant if used correctly. Object-based management can suffer from performance issues if the state tree is large and frequently updated.
- Proxy-based management can provide efficient updates by tracking only the necessary state changes.
Learning Curve:
- Object-based state management may be easier for developers familiar with traditional Redux-like patterns.
- Proxy-based state management, while powerful, requires understanding Proxies and reactive patterns, which can have a steeper learning curve.
**Use Cases:**
**Object-Based:** Ideal for applications where state transitions need to be explicitly managed and debugged, such as complex enterprise applications.
**Proxy-Based:** Suitable for applications where ease of state management and reactivity are prioritized, such as real-time data dashboards or interactive interfaces.
**Conclusion**
Both Redux and Valtio offer powerful state management solutions with distinct advantages. Redux excels in predictability and tooling for complex applications, while Valtio provides simplicity and automatic reactivity for straightforward state management. Choosing the right tool depends on your application’s needs and your team’s familiarity with the respective libraries.

It... | 0 | 2024-07-13T04:25:24 | https://dev.to/adah_okwara_3c43c95a89a2e/creating-an-azure-virtual-network-with-four-subnets-19214830026-478l | azure, cloudcomputing, networking, microsoft |
A virtual network (VNet) in Azure acts as the foundation for your private cloud environment. It defines a secure communication space for your Azure resources, including virtual machines (VMs). This blog will guide you through creating a VNet with four subnets using the address space 192.148.30.0/26.
**Prerequisites:**
- An Azure account with an active subscription
**Steps**
**1.Access the Azure Portal:**
Log in to the Azure portal https:[//azure.microsoft.com/en-us/get-started/azure-portal](url) using your Azure account credentials.
**2.** **Create a Virtual Network:**
- In the Azure portal search bar, type "Virtual Network" and select the service from the results.
- Click on the "+ Create" button.
**3.** **Configure Virtual Network Settings:**
- Provide a unique name for your VNet (e.g., "MyVNet").
- Select the appropriate subscription that you want to use for this virtual network.
- Choose a resource group or create a new one to organize your Azure resources.
- Select the appropriate location for your VNet deployment.
- Click on the IP Address on your top left options
**4.** **Define the IP Address Space:**
- For the "Address space" field, enter "192.148.30.0/26" as the address space for the virtual network.
- A /26 subnet mask provides 64 usable IP addresses within the VNet.
- Leave the other settings at their default values and click on the "Next: Subnets" button.
**5.** **Create and Configure the Subnets:**
- Click on "+ Subnet" to add a new subnet.
- Provide a name for your subnet (e.g., "Subnet1").
- Define the subnet address range. In this step, you'll divide the /26 VNet address space (192.148.30.0/26) into four subnets. To achieve this, you'll use a /28 subnet mask. This configuration provides 16 usable IP addresses per subnet, offering a balanced approach for your four-subnet virtual network.
- Subnet 1:
1. Name: Subnet 1
2. Subnet address range: 192.148.30.0/28
3. Click "Add".
- Subnet 2
1.Name: Subnet 2
2.Subnet address range: 192.148.30.16/28
3. Click "Add"
- Subnet 3
1.Name: Subnet 3
2.Subnet address range: 192.148.30.32/28
3.Click "Add"
- Subnet 4
1. Name: Subnet 4
2. Subnet address range: 192.148.30.48/28
3. Click " Add"
**6**. **Review and create the virtual network**
1. Review the configuration details of your VNet and subnets to ensure they are correct.
2. Once satisfied, click on the "Review + create" button to validate the settings.
3. After validation is successful, click on the "Create" button to deploy your virtual network with the four subnets
**Excellent work!** You've meticulously divided your Azure virtual network's /26 address space (192.148.30.0/26) into four efficiently sized subnets, providing a solid foundation for deploying your resources.

> Generative AI transforms the way we handle business logic
If you read the title and thought I am going to introduce Copilot, you are wrong.
Before we start the topic, let's start with a case study of an e-commerce platform.
Suppose the shopping cart looks like the following.
```json
[
{
"product_id": 123,
"amount": 2,
"price": 10.99,
"category_id": 1
},
{
"product_id": 456,
"amount": 1,
"price": 29.99,
"category_id": 2
},
{
"product_id": 789,
"amount": 5,
"price": 1.99,
"category_id": 3
}
]
```
Each field should be simple enough to contain the item purchased, the quantity purchased, the price of the single item, and the category it belongs to.
I have 3 promotions.
1. $5 off a $20 purchase, which continues to accrue after qualifying.
2. buy 2 get 1 free on category_id 1 items.
3. 30% off the total price of category_id 3 items.
- What is the total price after calculation?
- How much of the discount is allocated to each item?
To implement such promotions, please answer the following questions.
- How long would it take you to write this logic?
- Can you make the logic better than O(n^2)?
The first question is easy to understand, but what does the second question mean?
We have three promotions, and to be able to determine the impact of every promotion we need to scan the entire shopping cart for every item. So, in the example above, that's `3 * 3 = 9`, i.e. O(n^2).
### Then
What if I told you:
- I could do it in just a few minutes.
- And it's O(1).
Would you believe me?
Guess how I did it.
### GenAI can help
Although GenAI was mentioned, if you thought I am going to introduce Copilot or similar tools you are very wrong.
It's true that those code generation tools can produce business logic in a matter of minutes, but the business logic they produce will still work the way we think, which means it will still be O(n^2).
So what do we do with GenAI? The answer is simple: let GenAI learn business logic and then answer the results directly.
Sounds unbelievable, right? Let's see how I did it.
[GEMINI DEMO LINK](https://aistudio.google.com/app/prompts?state=%7B%22ids%22:%5B%221l57m9Y-lzOoiVLVSej8RSPlquod_QnFl%22%5D,%22action%22:%22open%22,%22userId%22:%22112447852159053274838%22,%22resourceKeys%22:%7B%7D%7D&usp=sharing)
Even though I'm using Gemini as an example, actually, you can use any model.
### Step 1
First, I'll tell Gemini his role using `System Instructions`.
> You are an e-commerce expert who is well versed in all kinds of promotions and understands how shopping cart profits are calculated.
### Step 2
Next, ask Gemini to explain the structure of a shopping cart that I dropped in. It's important to ask him to explain this. Instead of telling him what it is, it's better to let him understand it for himself so that he can get a more accurate mental model.
> Let's describe a shopping cart in JSON, here's an example.
### Step 3
Tell Gemini what he needs to know about the promotion, and explain in detail what we need. This echoes the question at the beginning of this article. The point of this step, by the way, is not just to explain the promotion, but also to tell him what results to send back.
### Step 4
Based on Gemini's thought process, we have to keep correcting it until his understanding and calculations are correct. Fortunately, GenAI doesn't hide anything. He tells us step by step what he's thinking, so it's easy to find mistakes in the middle. I have to say, it's much easier to debug a natural language than a programmed language.
### Step 5
Ask Gemini to generate a response structure that corresponds to the requirements in step 3, which is why I said we should tell him what we want as early as possible. If we don't tell him as early as possible, we may need to go back and adjust his thought process at this step, which would be very ineffective.
### Final step
Because GenAI will still keep "describing" his answer, we have to tell him, "I don't want to see the process, I just want to see the result, and I don't want any description".
Finally, the business logic is complete.
Wait, that's a little weird. We don't deal with business logic this way by interacting with GenAI.
Yes, that's right! The first step to the last step are all pre-defined "prompts", and we can get the result by wrapping all these prompts and business logic inputs in the same question and asking GenAI.
In fact, it looks like this.
https://gist.github.com/wirelessr/85ed1e1616513a4fcd4bdc3ad5f7874b
The `INSERT_INPUT_HERE` is actually the original structure of our shopping cart promotion calculation.
This process is exactly the same as the popular prompt engineering nowadays.
## Conclusion
In this article we have shown a case study of using GenAI to accomplish business logic.
Let's organize the whole process again.
1. Inform about the role of GenAI
2. Explain the input of the business logic.
3. Describe the requirements of the business logic.
4. Correct GenAI's errors.
5. Generate the output of the business logic.
6. Prune all descriptive statements.
These steps are all centered around prompt engineering, and the more you are familiar with prompt engineering, the quicker the process will be.
The benefits of this process are not only that we can make O(n^2) business logic processing become O(1) as mentioned at the beginning, but also that we can make business logic easier to debug. As I said, it's much easier to catch human speech defects than it is to find bugs in a program.
Nevertheless, there is one important thing to realize about this development process. We have to realize that GenAI is actually a Large Language Model, or LLM, which is not good at computation. So when we use GenAI to write business logic, we still need to have full unit testing to make sure the results are what we expect.
In other words, the importance of unit testing increases rather than decreases with this development process.
When we think of GenAI for software development, we always think of Copilot, but it's much simpler to let GenAI implement business logic directly without generating code. | lazypro |

Here's how we achieved a more than 3x reduction in our bundle size, speeding up our build process and enhancing our app's runtime efficiency.
## The Power of Tree Shaking
Tree shaking is a term commonly used in the JavaScript context for dead-code elimination. It relies on the static structure of ES modules, which allows unused exports to be removed during the bundling process.
Our project uses Material UI extensively, a popular React UI framework known for its comprehensive component library.
Initially, our bundle size was bloated due to importing entire libraries, even when only using specific components.
To address this, we implemented stricter import rules using ESLint to ensure that every component is imported directly from its path:
```jsx
// ESLint rules for Tree Shaking
"no-restricted-imports": [
"error",
{
paths: [

"!@material-ui/core/styles/*",
"!@material-ui/core/colors/*",
"!@material-ui/pickers/typings/*",
]
}
]
}
]
```
Thus, if we attempt to use an import like this:
```jsx
import { useMediaQuery } from '@material-ui/core';
```
ESLint will flag an error with the message: '@material-ui/core' import is restricted from being used. Import should be formatted as follows: Import Example from "@material-ui/core/Example".
It will prompt us to correct the import as shown below:
```jsx
import useMediaQuery from '@material-ui/core/useMediaQuery';
```
This change enforced that developers import only what they need, significantly reducing the initial load time by cutting down unnecessary code from the bundle.
## Embracing Lazy Loading with @loadable/components
Lazy loading is a design pattern commonly used in web development to defer initialization of objects until the point at which they are needed.
It can significantly reduce the initial load time and positively impact performance.
We incorporated lazy loading using the `@loadable/component` library, which integrates seamlessly with our server-side rendering setup. Here's an example of how we used it:
```jsx
import React, { Suspense } from "react";
import TextInput from "@material-ui/core/TextField";
import loadable from "@loadable/component";
const SearchSuggestion = loadable(() => import("./SearchSuggestion"));
export const SearchInput = React.forwardRef((props, ref) => {
const { suggestions, value, onChange} = props;
return (
<>
<TextInput
ref={ref}
value={value}
onChange={onChange}
/>
{suggestions.length > 0 ? (
<Suspense>
<SearchSuggestion
items={suggestions}
maxSuggestions={3}
/>
</Suspense>
) : null}
<>
)
})
```
In this example we are lazy loading the suggestion items only when `suggestions` is greater than 1.
Using `@loadable/component` allowed us to split our codebase into smaller chunks that are only loaded when required.
This approach not only reduced the load time but also decreased the time-to-interactive, enhancing the user experience by not loading heavy components upfront.
This library was causing some conflicts when testing components with Jest. To address this, we created the following mock setup:
```jsx
import React from "react";
export const mockLoadable = (load) => {
let Component;
// Capture the component from the module load function
const loadPromise = load().then(
(val) => (Component = val.default)
);
// Create a react component which renders the loaded component
const Loadable = (props) => {
if (!Component) {
throw new Error(
"Bundle split module not loaded yet, ensure you beforeAll(() => MyLazyComponent.load()) in your test, import statement: " +
load.toString()
);
}
return <Component {...props} />;
};
Loadable.load = () => loadPromise;
return Loadable;
};
```
Then, in the component that leverages Loadable, when we needed to test it, we included at the beginning of our test files:
```jsx
jest.mock('@loadable/component', () =>
jest.requireActual('../testing/testUtilities/mockLoadable')
);
```
This setup ensures that the asynchronous components are properly handled in our Jest tests, providing a stable environment for unit testing.
export default mockLoadable;
## Advanced Code Splitting Using Vite
To further optimize our application, we embraced advanced code splitting strategies using Vite, which allowed us to push only the necessary code to production.
This approach was critical in reducing our bundle size significantly.
Here's the Vite configuration we used to achieve this:
```jsx
import { defineConfig, splitVendorChunkPlugin } from "vite";
import react from "@vitejs/plugin-react-swc";
import tsPaths from "vite-tsconfig-paths";
import { visualizer } from "rollup-plugin-visualizer";
export default defineConfig({
server: {
https: false,
port: 5173,
},
base: "./",
plugins: [react(), tsPaths(), visualizer(), splitVendorChunkPlugin()],
optimizeDeps: {
force: true,
},
define: { "process.env.NODE_ENV": '"production"' },
build: {
outDir: "./build",
rollupOptions: {
output: {
manualChunks: {
"react-vendor": ["react", "react-dom", "react-router-dom"],
"react-spring-carousel": ["react-spring-carousel"],
"material-ui": ["@material-ui/core", "@material-ui/icons", "@material-ui/lab", "@material-ui/styles"],
"react-select": ["react-select"],
},
},
},
},
});
```
Vite's flexible configuration supports manual chunking, allowing you to experiment and understand how much space various library groups consume.
We also used `rollup-plugin-visualizer` to provide a visual representation of how much weight each library and dependency adds to the bundle.
This tool has been invaluable in helping us understand and optimize our dependency graph.
## Results and Conclusion
By implementing these optimizations, we observed a more than 3x reduction in our overall bundle size.
Our build times improved, and our application's performance increased dramatically, especially on mobile devices where bandwidth and processing power are more limited.
Adopting tree shaking, lazy loading, and manual code splitting with Vite requires an upfront investment in configuring and enforcing best practices, but the payoff in terms of performance can be substantial.
If you're using a component library like Material UI, consider these strategies to optimize your application's bundle size and runtime efficiency.
I encourage all developers to review their import statements, consider lazy loading, and explore advanced code splitting to improve performance.
Being vigilant and proactive about performance will consistently yield positive results.

1,921,868 | Crafting React Components: Readability, Reusability, and Efficiency | In the world of React, writing components is an art. It’s not just about making them work — it’s... | 0 | 2024-07-13T03:04:53 | https://dev.to/vyan/crafting-react-components-readability-reusability-and-efficiency-6a1 | webdev, javascript, beginners, react | In the world of React, writing components is an art. It’s not just about making them work — it’s about making them work well. Today, we’re going to look at how to craft your components like a pro, focusing on readability, reusability, and efficiency.
## Create a List Component
Let’s start with a basic List component:
```javascript
// src/components/List.js
import React from 'react';
const List = ({ data }) => {
return (
<ul>
{data.map((item, index) => (
<li key={index}>{item}</li>
))}
</ul>
);
};
export default List;
```
This component takes an array of data and renders it as a list. While simple, this component can be enhanced to be more versatile and robust.
### Improving List Component with Prop Types and Default Props
Enhancing our List component to include Prop Types and Default Props can increase its reliability and usability:
```javascript
// src/components/List.js
import React from 'react';
import PropTypes from 'prop-types';
const List = ({ data }) => {
return (
<ul>
{data.map((item, index) => (
<li key={index}>{item}</li>
))}
</ul>
);
};
List.propTypes = {
data: PropTypes.arrayOf(PropTypes.string).isRequired,
};
List.defaultProps = {
data: [],
};
export default List;
```
By adding Prop Types, we ensure that the `data` prop is an array of strings, helping to catch potential bugs early. The default props ensure that our component still renders gracefully even if no data is provided.
## Enhancing Components with HOCs
Higher-Order Components (HOCs) are a powerful pattern for reusing component logic. They essentially wrap a component to extend its functionality without altering its structure.
### Creating a withLoading HOC
For example, a `withLoading` HOC can be used to display a loading state:
```javascript
// src/hocs/withLoading.js
import React from 'react';
function withLoading(Component) {
return function WithLoading({ isLoading, ...props }) {
if (isLoading) {
return <div>Loading...</div>;
}
return <Component {...props} />;
};
}
export default withLoading;
```
This HOC checks the `isLoading` prop. If it’s true, it renders a “Loading…” message. Otherwise, it renders the wrapped component, allowing for a seamless user experience during data fetching.
### Creating a withErrorHandling HOC
Similarly, `withErrorHandling` is another HOC that can manage error states:
```javascript
// src/hocs/withErrorHandling.js
import React from 'react';
function withErrorHandling(Component) {
return function WithErrorHandling({ error, ...props }) {
if (error) {
return <div>Error: {error.message}</div>;
}
return <Component {...props} />;
};
}
export default withErrorHandling;
```
When an error occurs, `withErrorHandling` displays an error message. Otherwise, it renders the component as usual. This HOC is particularly useful for handling fetch errors or issues within the component lifecycle.
### Combining HOCs for Robust Components
By combining `withLoading` and `withErrorHandling`, we can create a robust component that handles both loading and error states elegantly:
```javascript
// src/components/EnhancedList.js
import React from 'react';
import withLoading from '../hocs/withLoading';
import withErrorHandling from '../hocs/withErrorHandling';
import List from './List';
const ListWithLoading = withLoading(List);
const EnhancedList = withErrorHandling(ListWithLoading);
export default EnhancedList;
```
This approach promotes code reuse and separation of concerns, making our components more maintainable and easier to understand.
## Fetching Data with Hooks
React hooks allow us to use state and other React features without writing a class. `useFetch` is a custom hook that fetches data from an API:
```javascript
// src/hooks/useFetch.js
import { useState, useEffect } from 'react';
const useFetch = (url) => {
const [data, setData] = useState([]);
const [isLoading, setLoading] = useState(false);
const [error, setError] = useState(null);
useEffect(() => {
const fetchData = async () => {
setLoading(true);
try {
const response = await fetch(url);
if (!response.ok) {
throw new Error('Network response was not ok');
}
const json = await response.json();
setData(json);
} catch (error) {
setError(error);
} finally {
setLoading(false);
}
};
fetchData();
}, [url]);
return { data, isLoading, error };
};
export default useFetch;
```
This hook handles the fetching state, data storage, and errors, making it easy to fetch and display data in our components.
### Adding Caching to useFetch Hook
To improve the efficiency of our `useFetch` hook, we can add basic caching:
```javascript
// src/hooks/useFetch.js
import { useState, useEffect } from 'react';
const cache = {};
const useFetch = (url) => {
const [data, setData] = useState([]);
const [isLoading, setLoading] = useState(false);
const [error, setError] = useState(null);
useEffect(() => {
const fetchData = async () => {
if (cache[url]) {
setData(cache[url]);
return;
}
setLoading(true);
try {
const response = await fetch(url);
if (!response.ok) {
throw new Error('Network response was not ok');
}
const json = await response.json();
cache[url] = json;
setData(json);
} catch (error) {
setError(error);
} finally {
setLoading(false);
}
};
fetchData();
}, [url]);
return { data, isLoading, error };
};
export default useFetch;
```
This caching mechanism stores fetched data in a cache object, reducing redundant network requests and improving performance.
## Assembling the App
Finally, we bring everything together in the `App` component:
```javascript
// src/App.js
import React from 'react';
import EnhancedList from './components/EnhancedList';
import useFetch from './hooks/useFetch';
const App = () => {
const { data, isLoading, error } = useFetch('https://api.example.com/data');
return (
<div>
<h1>List Component</h1>
<EnhancedList data={data} isLoading={isLoading} error={error} />
</div>
);
};
export default App;
```
We use our `useFetch` hook to load data and pass it to our `EnhancedList` component, which is enhanced with loading and error handling capabilities through our HOCs.
## Conclusion
Crafting components in React involves more than just making them functional; it's about ensuring they are readable, reusable, and efficient. By using HOCs to manage loading and error states, custom hooks to handle data fetching, and adding improvements such as Prop Types and caching, we can build robust and maintainable components that enhance the overall development experience. This approach not only simplifies our code but also makes it easier to manage and scale our applications.
By focusing on these best practices, you can elevate your React development skills and build applications that are not only functional but also elegant and efficient. | vyan |

# Unlocking Application Insights: Leveraging Spring Boot Actuator for Monitoring and Metrics
In the ever-evolving world of software development, having deep insights into your application's health and performance is no longer optional—it's essential. Imagine deploying a critical application to production, confident in its functionality, only to be met with unexpected downtime or performance bottlenecks. This scenario, unfortunately, is not uncommon and highlights the crucial need for robust application monitoring and metrics. This is where Spring Boot Actuator comes into play, offering a powerful suite of tools designed to provide comprehensive insights into the inner workings of your Spring Boot applications.
### Introduction to Spring Boot Actuator
Spring Boot Actuator is a sub-project within the Spring Boot ecosystem that provides production-ready features to help you monitor and manage your applications. It does this by exposing a set of HTTP endpoints, commonly referred to as "actuator endpoints," that offer valuable information about your application's health, metrics, environment configuration, and more. By default, these endpoints are exposed over HTTP, making it easy to integrate them with various monitoring and management tools.
Actuator endpoints are a key component of Spring Boot Actuator. They are essentially pre-configured REST endpoints that expose application information. Each endpoint provides access to a specific category of data. Let's delve into some of the most commonly used endpoints:
* **`/actuator/health`:** This endpoint provides an overall health check of your application. It aggregates information from various health indicators, such as database connectivity, disk space, and external service availability. The response will typically be a simple "UP" or "DOWN," but it can be customized to provide more granular details.
* **`/actuator/info`:** The `/info` endpoint allows you to expose custom application information. This can be particularly useful for storing build-related data like version numbers, timestamps, or Git commit hashes, which can be valuable for troubleshooting and version management.
* **`/actuator/metrics`:** This endpoint exposes a wealth of metrics about your application, including JVM memory usage, garbage collection statistics, thread counts, and HTTP request statistics. These metrics provide valuable insights into your application's performance and resource utilization.
* **`/actuator/beans`:** The `/beans` endpoint lists all the Spring beans defined in your application context. This can be incredibly helpful for understanding how your application is wired together and identifying any potential issues with bean creation or configuration.
* **`/actuator/env`:** This endpoint displays the environment variables and system properties available to your application. It's particularly useful for debugging configuration issues and ensuring that your application has access to the correct environment-specific settings.
### Use Cases for Spring Boot Actuator
Let's explore some compelling use cases that demonstrate the versatility and power of Spring Boot Actuator in real-world application monitoring and management scenarios.
**1. Real-Time Health Monitoring and Alerting**
One of the most critical aspects of application management is ensuring its continuous availability. Spring Boot Actuator's health endpoint provides a simple yet effective way to monitor the health of your application. By periodically querying the `/actuator/health` endpoint, you can receive real-time updates on the status of your application and its dependencies.
**Implementation:** Configure your monitoring system to periodically make GET requests to the `/actuator/health` endpoint. Based on the response ("UP" or "DOWN"), you can trigger alerts or notifications. For more detailed health checks, customize the health indicators to include checks specific to your application's dependencies, like database connections or message queues.
**2. Performance Monitoring and Tuning**
Understanding how your application performs under different load conditions is crucial for optimizing resource utilization and ensuring a seamless user experience. Spring Boot Actuator's metrics endpoints expose a wealth of performance data, allowing you to identify bottlenecks and fine-tune your application's configuration.
**Implementation:** Utilize tools like Prometheus or Graphite to scrape metrics exposed by endpoints like `/actuator/metrics`. Visualize these metrics using dashboards to track key performance indicators (KPIs) such as request latency, throughput, and resource consumption. This data can help identify performance bottlenecks and areas for optimization.
**3. Automated Healing and Self-Remediation**
In a microservices architecture, where applications are often deployed in containers with orchestrators like Kubernetes, automated healing is essential for maintaining system resilience. Actuator's health endpoints can be integrated with orchestration platforms to automate container restarts or service failovers when an application becomes unhealthy.
**Implementation:** Configure Kubernetes liveness probes to periodically check the `/actuator/health` endpoint. If the probe detects an unhealthy state, Kubernetes can automatically restart the container, potentially resolving transient issues. Similarly, readiness probes can use the health endpoint to determine when a container is ready to serve traffic after startup.
**4. Security Auditing and Compliance**
In security-sensitive environments, it's essential to audit and monitor access to application resources. Actuator's endpoints can be used to track HTTP requests, authenticate clients, and enforce access control policies, ensuring that only authorized users can access sensitive data.
**Implementation:** Integrate Spring Security with Actuator to restrict access to actuator endpoints. Define roles and permissions, allowing only authorized personnel (e.g., system administrators) to view sensitive data exposed by Actuator. Log access attempts to Actuator endpoints for auditing purposes.
**5. Dynamic Configuration Updates**
Actuator provides endpoints like `/actuator/refresh` and `/actuator/env` that allow you to dynamically update your application's configuration without requiring a restart. This can be incredibly useful for making runtime adjustments to application settings, such as log levels, feature flags, or database connection parameters.
**Implementation:** Externalize configuration properties using a configuration server like Spring Cloud Config Server. When configuration changes are detected, Actuator's `/actuator/refresh` endpoint can be triggered to reload the modified properties, allowing your application to adapt to changes dynamically.
### Alternatives to Spring Boot Actuator
While Spring Boot Actuator offers a robust and comprehensive solution for application monitoring and management within the Spring ecosystem, there are alternative tools and frameworks available:
* **Micrometer:** Micrometer is a vendor-neutral application metrics facade for JVM-based applications. It provides a common API for collecting and emitting metrics to various monitoring systems.
* **Prometheus:** Prometheus is an open-source systems monitoring and alerting toolkit. It's particularly well-suited for monitoring containerized environments and integrates well with Kubernetes.
* **Datadog, New Relic, Dynatrace:** These are commercial Application Performance Monitoring (APM) solutions that provide deep insights into application performance, user experience, and infrastructure health.
### Conclusion
In the ever-evolving landscape of software development, embracing tools and practices that promote transparency and provide real-time insights into application health and performance is crucial. Spring Boot Actuator empowers developers with a comprehensive toolkit to monitor, manage, and optimize Spring Boot applications effectively. By integrating Actuator into your application development workflow, you gain access to a wealth of information that can significantly enhance your ability to troubleshoot issues, optimize performance, and ensure the smooth operation of your applications.
### Advanced Use Case: Distributed Tracing with Spring Cloud Sleuth
For this advanced use case, let's delve into how we can leverage Spring Boot Actuator in conjunction with Spring Cloud Sleuth to implement distributed tracing in a microservices architecture.
**The Challenge:** In a microservices-based system, a single user request often traverses multiple services. This complexity makes it challenging to pinpoint performance bottlenecks or diagnose issues that span multiple service boundaries.
**The Solution:** Distributed tracing provides a way to track a request as it flows through different services, providing a holistic view of the request's journey and timing information for each step.
**Implementation Details:**
1. **Integrate Spring Cloud Sleuth:** Add the Spring Cloud Sleuth dependency to your project. Sleuth automatically instruments your Spring Boot applications, adding unique trace IDs and span IDs to outgoing requests.
2. **Configure a Tracing Backend:** Choose a tracing backend such as Zipkin or Jaeger to collect and visualize tracing data.
3. **Expose Tracing Data via Actuator:** Ensure that the `/actuator/trace` endpoint is enabled in your application's Actuator configuration. Sleuth will automatically expose tracing data through this endpoint.
4. **Monitoring and Analysis:** Use your chosen tracing backend's UI to visualize the collected tracing data. You can see the flow of requests across services, identify performance bottlenecks, and diagnose issues more effectively.
**Benefits:**
* **End-to-End Request Tracking:** Gain a comprehensive view of how requests flow through your microservices ecosystem, enabling you to pinpoint performance bottlenecks or errors at any stage of the request lifecycle.
* **Improved Debugging and Troubleshooting:** Quickly identify the root cause of issues by tracing requests across service boundaries, reducing mean time to resolution (MTTR).
* **Enhanced System Understanding:** Visualize service dependencies and interactions, providing valuable insights into the overall architecture and behavior of your microservices system.

A 2009 study shows that the average time for a new habit to stick is about 66 days. So even if we try to build a habit in 21 days, it is most unlikely to stick to our lifestyle.
There comes the concept of the 21-90 rule. It states that it takes about 21 days to build a habit but 90 days to make it a permanent lifestyle change. The idea here is as clear as water- you take action on a longer streak to ensure you don't revert to your original state.
---
Talking about me, I always wanted to build a programming habit in my daily schedule. As a beginner in my developing journey, I wish to learn
new tech stacks and contribute to open-source projects. For this, I need to regularly study and practice. For that, I've decided to take a challenge and start coding every day until it becomes a natural part of my lifestyle. I would try to learn and practice new programming concepts each day for 21 days, and track down the progress of each day in a series of articles.

1,921,906 | Enhancing Web Performance with Image Sprites | In the fast-paced world of web development, optimizing the performance of your website is crucial.... | 0 | 2024-07-13T06:56:09 | https://dev.to/mdhassanpatwary/enhancing-web-performance-with-image-sprites-54n5 | webdev, css, html, learning | In the fast-paced world of web development, optimizing the performance of your website is crucial. One effective technique for improving load times and overall user experience is the use of image sprites. By combining multiple images into a single sprite, you can reduce the number of HTTP requests, leading to faster page loads and better performance. This article will explain what image sprites are, their benefits, and how to implement them in your web projects.
## What is an Image Sprite?
An image sprite is a single image file that contains multiple individual images. By using CSS, you can display specific portions of this large image on different parts of a web page. This approach minimizes the number of HTTP requests required to load a web page, as only one image file is fetched instead of multiple individual files.
## Benefits of Using Image Sprites
**1. Reduced HTTP Requests:** Each image on a webpage typically requires a separate HTTP request. By combining images into a single sprite, you reduce the number of requests, which can significantly speed up page load times.
**2. Improved Performance:** Fewer HTTP requests mean less overhead and faster rendering of the web page.
**3. Better Caching:** A single sprite image is easier to cache than multiple images, leading to better performance on subsequent visits.
## How to Create and Use an Image Sprite
**Step 1: Create the Sprite Image**
Start by combining all the individual images into one large image using an image editing tool like Photoshop, GIMP, or an online sprite generator. Arrange the images in a grid or row, ensuring consistent spacing between them if necessary.
Example sprite image:
```
+------------------+
| Image 1 | Image 2 |
+------------------+
| Image 3 | Image 4 |
+------------------+
```
**Step 2: Define the Sprite in CSS**
Next, define CSS classes for each image, specifying the dimensions and the background position to display the correct part of the sprite.
```
/* Define the sprite */
.sprite {
background-image: url('path/to/sprite.png');
background-repeat: no-repeat;
display: inline-block;
}
/* Individual images */
.image1 {
width: 50px; /* width of the individual image */
height: 50px; /* height of the individual image */
background-position: 0 0; /* position of Image 1 */
}
.image2 {
width: 50px;
height: 50px;
background-position: -50px 0; /* position of Image 2 */
}
.image3 {
width: 50px;
height: 50px;
background-position: 0 -50px; /* position of Image 3 */
}
.image4 {
width: 50px;
height: 50px;
background-position: -50px -50px; /* position of Image 4 */
}
```
In this example, each image within the sprite is 50x50 pixels. The `background-position` property shifts the background image so that the correct portion of the sprite is displayed.
**Step 3: Use the Sprite in HTML**
Finally, use the defined CSS classes in your HTML to display the images.
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Image Sprite Example</title>
<style>
.sprite {
background-image: url('sprite.png');
background-repeat: no-repeat;
display: inline-block;
}
.image1 {
width: 50px;
height: 50px;
background-position: 0 0;
}
.image2 {
width: 50px;
height: 50px;
background-position: -50px 0;
}
.image3 {
width: 50px;
height: 50px;
background-position: 0 -50px;
}
.image4 {
width: 50px;
height: 50px;
background-position: -50px -50px;
}
</style>
</head>
<body>
<div class="sprite image1"></div>
<div class="sprite image2"></div>
<div class="sprite image3"></div>
<div class="sprite image4"></div>
</body>
</html>
```
## Conclusion
Using image sprites is a powerful technique to enhance web performance by reducing the number of HTTP requests. It is particularly useful for websites with many small images, such as icons or buttons. By carefully crafting the sprite and using CSS, you can ensure that your web pages load faster and run more efficiently. Embrace the power of image sprites to deliver a smoother and more responsive user experience on your websites. | mdhassanpatwary |

Creating and publishing a WordPress plugin can enhance the functionality of WordPress websites. This guide will walk you through the steps to create a simple WordPress plugin and publish it on the WordPress Plugin Directory.
## Prerequisites
Before you start, ensure you have the following:
- Basic knowledge of PHP and WordPress.
- A local development environment with WordPress installed.
- Access to a code editor (like VSCode or Sublime Text).
## Step 1: Setting Up Your Plugin
1. **Create a Plugin Folder**:
In your WordPress installation, navigate to the `wp-content/plugins` directory and create a new folder for your plugin. Name it descriptively, for example, `my-awesome-plugin`.
2. **Create the Main Plugin File**:
Inside your plugin folder, create a PHP file with the same name as your plugin folder, e.g., `my-awesome-plugin.php`.
3. **Add Plugin Header**:
Open the PHP file and add the following header information at the top:
```php
<?php
/*
Plugin Name: My Awesome Plugin
Plugin URI: http://example.com/my-awesome-plugin
Description: A brief description of what your plugin does.
Version: 1.0
Author: Your Name
Author URI: http://example.com
License: GPL2
*/
```
## Step 2: Writing Your Plugin Code
1. **Add Basic Functionality**:
Let's create a simple plugin that adds a custom message to the footer of your WordPress site.
```php
// Add a custom message to the footer
function my_awesome_plugin_footer_message() {
echo '<p style="text-align: center;">This is a custom message from My Awesome Plugin.</p>';
}
add_action('wp_footer', 'my_awesome_plugin_footer_message');
```
2. **Save Your Changes**:
Save the `my-awesome-plugin.php` file and ensure it's in the `wp-content/plugins/my-awesome-plugin` directory.
## Step 3: Activating Your Plugin
1. **Log in to Your WordPress Admin**:
Go to the WordPress admin panel of your local development site.
2. **Navigate to the Plugins Page**:
Go to `Plugins` > `Installed Plugins`.
3. **Activate Your Plugin**:
Find your plugin in the list and click the `Activate` button.
## Step 4: Testing Your Plugin
Visit the front end of your WordPress site and scroll to the footer. You should see the custom message added by your plugin.
## Step 5: Preparing Your Plugin for Distribution
1. **Create a Readme File**:
Create a `readme.txt` file in your plugin folder. This file provides important information about your plugin.
```txt
=== My Awesome Plugin ===
Contributors: yourname
Tags: custom footer, custom message
Requires at least: 5.0
Tested up to: 6.0
Stable tag: 1.0
License: GPLv2 or later
License URI: http://www.gnu.org/licenses/gpl-2.0.html

Understand Issues
An issue in like a wildfire it starts small but has the potential to burn the whole forest and in this case your relationship with your boss, don't allow it to spread any longer
>"Fire must be extinguished the moment it is lit"
the same principle applies to an issue you must resolve it the moment it became an issue. Before making any bold statements about your boss and his/her actions rethink and reconsider because a boss or any managing position's actions are directed towards the betterment of the company as a whole and not just some selected few, Now that you have reconsidered and reevaluated your bosses actions act accordingly; with a cool and peaceful mind and try to calm your boss before you start making any suggestions.
#2. Open Dialogue
A open dialogue is a great way of sharing thoughts with your boss or subordinates, and is a great way to resolve any issues you may have.
>In a open dialogue always try to be a active listener rather then a active speaker and try to point out the major issues first because sometimes one resolved major issue automatically resolves many small issues.

```
Nothing much, huh? But, the problem is, the code should have been this way:
뭐, 별거 없긴 합니다만, 사실 문제는 코드가 원래 이런 식이어야 했다는 겁니다:
```cpp
if(condition1) do_something();

1,921,915 | Cut Off Without a Goodbye: My Final Hours at the Company | The abrupt way that my relationship with my former company ended, and our cold interactions since... | 0 | 2024-07-13T04:01:56 | https://dev.to/sarah_bruce_83fc98defc6d5/cut-off-without-a-goodbye-my-final-hours-at-the-company-22f7 | womenintech, workplace, career | The abrupt way that my relationship with my former company ended, and our cold interactions since then, hurt like hell. I went from being told how important I was to the company, to being quickly removed from Slack. It’s been humbling, to say the least.
(For those who haven’t seen my [previous post](https://dev.to/sarah_bruce_83fc98defc6d5/i-was-told-its-not-discrimination-3ceg), I faced hostile and dismissive behavior for two years and eventually decided to leave the company because of it.)
## Friday, May 24
**~10:30 AM CT**
I was halfway through my two weeks notice. We had an all hands meeting and I asked my manager if there were plans to announce my upcoming departure - he said no.
**~10:50 AM CT**
During the meeting, the CEO announced the upcoming departure of a different employee, thanking her for her contributions and giving her a nice sendoff. Then the meeting moved on without any mention of me. In what seemed like a cruel joke by the universe, the other employee’s name was also Sarah. Seeing the Zoom chat blow up with messages like “Goodbye Sarah!” and “We’ll miss you Sarah!” felt like a knife through the heart.
**~10:51 AM CT**
I DM’d my manager and told him I had to leave the meeting because I was so upset. He never responded.
**~10:51 - 11:05 AM CT**
I broke down in tears. All of the emotions from the past two years were resurfacing at once. This was the last heartbreak I could endure at the company.
**~11:05 AM CT**
I messaged HR and told them I wanted that day to be my last day.
**~11:15 AM CT**
After the all hands meeting ended, the CEO DM’d me asking if I could talk. I told him I wasn’t in an emotional state to talk at the moment. I assume he was going to give me an excuse for what happened during all hands.
**~11:35 AM CT**
I received a Slackbot notification saying my manager had removed me from the internal engineering channel. This was the channel I was going to use to say goodbye to my team. I later found out:
1. Some of my coworkers in that channel thought I’d left the channel on my own since it said “Sarah left #engineering-internal” and my manager never let them know he’d actually removed me.
2. After I was removed, my manager called a team meeting in the channel and told them that was my last day. I didn’t even know this was going on. Why wasn’t I invited and given an opportunity to see my team one last time?
**~11:45 AM CT**
The HR rep called me and offered to let me go early, instead of waiting until the end of the day. I told her I’d prefer to wait until the end of the day so that I could say bye to my team and other close coworkers, and wrap up a few things. She told me that most people were at lunch, so nobody would be around for me to say bye to, so we might as well wrap me up early. She said I could draft a goodbye note to the team, and email it to her and she would send it on my behalf. I called BS on her reasoning of everyone being at lunch, but said she could do whatever she needed. She told me I’d lose access to everything soon.
**~11:50 AM CT**
I hurriedly typed a goodbye message in a channel I still had access to. Right before I hit send, Slack logged me out. I was officially cut off from the company I’d spent the last seven years with.
I sat there, shocked at what had just happened over the course of an hour. Shocked that the company could discard me so quickly and coldly. At 10:30 that morning I was one of the most tenured people at the company, imagining what my heartfelt goodbye from my manager would be like. By noon I was an ex-employee who had received no goodbye from my manager, publicly or privately.
---
I know that I’m the one who decided to exit four days earlier than planned. But that was only because of yet another mess-up on the company’s part. Did I not still deserve to be told “Thank you for everything you’ve done for our company. We wish you the best”? Could they not have sent a quick message in the #people channel saying “Please join us in wishing Sarah Bruce farewell. Today marks her last day with the company”? Instead, a private team meeting was held behind my back. Then I was cut off.
The feeling of betrayal and lack of closure have almost been too much to bear. To some people, their employer is simply a place they clock in and out of, with no personal attachment. To me, the company was my family. I joined as the first full-time web developer. There were only 15 other employees at the time. At our annual summit a few months ago, the CEO looked at me and said “we built this”, referring to the large crowd of employees dancing and laughing on the dancefloor. We had taken our small startup and turned it into something more magical than we could have imagined. And now I’m sitting here typing this, still in disbelief.

4. **Rapid Prototyping:**
Valtio’s simplicity and ease of use make it ideal for rapid prototyping, allowing developers to quickly build and test features.
**Setting Up the Project:**
**Step 1:** **Initialize the Project with Bun**
First, ensure you have Bun installed. If not, you can install it from the official website.
```
bun create react my-react-app
cd my-react-app
```
**Step 2:** **Install Vite**
Since Bun doesn’t natively support Vite out of the box, we’ll integrate it manually.
_Install Vite and its dependencies:_
```
bun add vite @vitejs/plugin-react
```
2. _Create a vite.config.js file at the root of your project:_
```
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
export default defineConfig({
plugins: [react()],
});
```
**Step 3:** Set Up Valtio
Install Valtio using Bun:
```
bun add valtio
```
**Creating a Simple React App**
Let’s create a simple React app that uses Valtio for state management. We’ll start with a counter example.
**Step 4:** Create a React Component
In the src directory, create a file named App.jsx:
import React from 'react';
import { useSnapshot } from 'valtio';
import { proxy } from 'valtio';
const state = proxy({
count: 0,
});
function App() {
const snap = useSnapshot(state);
return (
<div>
<h1>Count: {snap.count}</h1>
<button onClick={() => state.count++}>Increment</button>
<button onClick={() => state.count--}>Decrement</button>
</div>
);
}
export default App;
**Step 5:** Update the Entry Point
Update the main.jsx file to use Vite's hot module replacement (HMR) and render the App component:
import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<App />
</React.StrictMode>
);
2. Make sure your index.html file is set up correctly:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>React App with Vite and Valtio</title>
</head>
<body>
<div id="root"></div>
<script type="module" src="/src/main.jsx"></script>
</body>
</html>
**Step 6:** Start the Development Server
Start your development server using Vite:
bun vite
This will start the Vite development server, and you should see your React app with the counter on http://localhost:3000.
**Key Features of Valtio:**
1. **Reactive State:** Automatically updates the UI when state changes.
2. **Simplicity:** Minimal API that is easy to learn and use.
3. **Derived State and Effects:** Supports derived state and side effects.
4. **TypeScript Support:** Excellent TypeScript support for type-safe state management.
**Primary Components of Valtio**
1. **proxy**
The proxy function creates a reactive state object. It uses JavaScript Proxies to track changes and ensure that any state updates are automatically reflected in the UI.
**Example:**
```
import { proxy } from 'valtio';
const state = proxy({
count: 0,
text: 'Hello, Valtio!'
});
```
1. **useSnapshot**
The useSnapshot hook subscribes to changes in the state and returns a snapshot of the state. This snapshot is automatically updated whenever the state changes, causing the component to re-render.
**Example:**
```
import { useSnapshot } from 'valtio';
const Counter = () => {
const snap = useSnapshot(state);
return (
<div>
<p>{snap.count}</p>
<button onClick={() => state.count++}>Increment</button>
</div>
);
};
```
3. **subscribe**
The subscribe function allows subscribing to changes in the state without using React components. This is useful for logging, debugging, or triggering side effects outside of React components.
**Example:**
```
import { subscribe } from 'valtio';
subscribe(state, () => {
console.log(`Count has changed to: ${state.count}`);
});
```
4. **derive**
The derive function creates derived state, which is computed from other state values. Derived state is automatically updated when the underlying state changes.
**Example:**
```
import { derive } from 'valtio/utils';
const derivedState = derive({
doubledCount: (get) => get(state).count * 2
});
```
5. **devtools**
The devtools function integrates Valtio with browser developer tools for easier debugging and state inspection.
**Example:**
```
import { devtools } from 'valtio/utils';
devtools(state, 'ValtioState');
```
Putting It All Together: A Sample Application
Let’s build a simple counter application to demonstrate how these components work together in a Valtio-based state management setup.
**Step 1:** Setting Up the State
```
// state.js
import { proxy } from 'valtio';
export const state = proxy({
count: 0,
increment() {
this.count++;
},
decrement() {
this.count--;
}
});
```
**Step 2:** Creating the Counter Component
```
// Counter.js
import React from 'react';
import { useSnapshot } from 'valtio';
import { state } from './state';
const Counter = () => {
const snap = useSnapshot(state);
return (
<div>
<p>Count: {snap.count}</p>
<button onClick={() => state.increment()}>Increment</button>
<button onClick={() => state.decrement()}>Decrement</button>
</div>
);
};
export default Counter;
```
**Step 3:** Integrating Derived State
```
// derivedState.js
import { derive } from 'valtio/utils';
import { state } from './state';
export const derivedState = derive({
doubledCount: (get) => get(state).count * 2
});
```
**Step 4:** Displaying Derived State
```
// DoubleCounter.js
import React from 'react';
import { useSnapshot } from 'valtio';
import { derivedState } from './derivedState';
const DoubleCounter = () => {
const snap = useSnapshot(derivedState);
return (
<div>
<p>Doubled Count: {snap.doubledCount}</p>
</div>
);
};
export default DoubleCounter;
```
**Step 5:** Integrating DevTools
```
// index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { devtools } from 'valtio/utils';
import { state } from './state';
import Counter from './Counter';
import DoubleCounter from './DoubleCounter';
devtools(state, 'ValtioState');
const App = () => (
<div>
<h1>Valtio Counter App</h1>
<Counter />
<DoubleCounter />
</div>
);
ReactDOM.render(<App />, document.getElementById('root'));
```
**Flow Control in Managing UI Application’s State with Valtio:**
Valtio is a modern state management library for React that leverages JavaScript Proxies to create reactive state objects. This article will delve into the flow control mechanisms in Valtio, explaining how it manages state changes, synchronizes state across components, and ensures optimal performance in a UI application.
**Key Concepts in Valtio:**
1. **Reactive State:** Valtio uses JavaScript Proxies to create reactive state objects, which automatically trigger re-renders in components when the state changes.
2. **Proxies:** Proxies intercept interactions with state objects, allowing Valtio to track and manage state changes efficiently.
3. **Snapshots:** Snapshots provide a way to use and observe the current state in React components.
4. **Derived State:** Derived state allows the creation of computed values based on the reactive state.
5. **Effects:** Effects enable executing side effects when the state changes.
**Flow Control in Valtio:**
The flow control in Valtio revolves around how state changes propagate through the application, ensuring that components stay in sync with the latest state. Here’s a detailed breakdown of the flow control process in Valtio:
1. **State Initialization**
State is initialized using the proxy function, which creates a reactive state object. This object will be used throughout the application to manage state changes.
**Example:**
```
import { proxy } from 'valtio';
const state = proxy({
count: 0,
increment() {
this.count++;
},
decrement() {
this.count--;
},
});
export default state;
```
2. **State Usage in Components**
React components use the useSnapshot hook to subscribe to state changes and get the current state. The useSnapshot hook ensures that components re-render automatically when the state changes.
**Example:**
```
import React from 'react';
import { useSnapshot } from 'valtio';
import state from './state';
const Counter = () => {
const snap = useSnapshot(state);
return (
<div>
<p>Count: {snap.count}</p>
<button onClick={() => state.increment()}>Increment</button>
<button onClick={() => state.decrement()}>Decrement</button>
</div>
);
};
export default Counter;
```
3. State Modification
State modifications are done directly on the state object. Valtio’s Proxy-based reactivity ensures that any changes to the state trigger re-renders in components that use the affected state.
**Example:**
```
state.increment(); // This will increment the count and trigger a re-render in subscribed components
```
4. Handling Asynchronous State Updates
Valtio supports asynchronous state updates seamlessly. You can define asynchronous functions within the state object to handle operations like data fetching.
**Example:**
```
import { proxy } from 'valtio';
const asyncState = proxy({
data: null,
loading: false,
error: null,
async fetchData() {
this.loading = true;
this.error = null;
try {
const response = await fetch('https://jsonplaceholder.typicode.com/todos/1');
const result = await response.json();
this.data = result;
} catch (error) {
this.error = error.message;
} finally {
this.loading = false;
}
}
});
export default asyncState;
```
5. Using Asynchronous State in Components
Components can use asynchronous state similarly to synchronous state. The useSnapshot hook will ensure that components re-render when the asynchronous state updates.
**Example:**
```
import React, { useEffect } from 'react';
import { useSnapshot } from 'valtio';
import asyncState from './asyncState';
const DataComponent = () => {
const snap = useSnapshot(asyncState);
useEffect(() => {
asyncState.fetchData();
}, []);
if (snap.loading) return <div>Loading...</div>;
if (snap.error) return <div>Error: {snap.error}</div>;
if (!snap.data) return null;
return (
<div>
<p>Data: {snap.data.title}</p>
</div>
);
};
export default DataComponent;
```
6. Derived State and Effects
Derived state and effects provide additional mechanisms to manage state flow and side effects in Valtio.
Derived State: Derived state allows the creation of computed values based on the reactive state.
**Example:**
```
import { derive } from 'valtio/utils';
const derivedState = derive({
doubleCount: (get) => get(state).count * 2,
});
export default derivedState;
```
**Using Derived State in Components:**
```
import React from 'react';
import { useSnapshot } from 'valtio';
import derivedState from './derivedState';
const DerivedComponent = () => {
const snap = useSnapshot(derivedState);
return (
<div>
<p>Double Count: {snap.doubleCount}</p>
</div>
);
};
export default DerivedComponent;
```
**Effects: Effects enable executing side effects when state changes.**
**Example:**
```
import { subscribe } from 'valtio';
subscribe(state, () => {
console.log(`Count has changed to: ${state.count}`);
});
```
**Advanced State Management with Valtio:**
**Step 7:** Implement More Complex State Logic
Valtio can handle more complex state logic. Let’s extend our example to include a to-do list.
Update the App.jsx file:
```
import React from 'react';
import { useSnapshot } from 'valtio';
import { proxy } from 'valtio';
const state = proxy({
count: 0,
todos: [],
});
function App() {
const snap = useSnapshot(state);
const addTodo = () => {
const newTodo = prompt('Enter a new to-do:');
if (newTodo) {
state.todos.push({ text: newTodo, done: false });
}
};
return (
<div>
<h1>Count: {snap.count}</h1>
<button onClick={() => state.count++}>Increment</button>
<button onClick={() => state.count--}>Decrement</button>
<hr />
<h2>To-Do List</h2>
<button onClick={addTodo}>Add To-Do</button>
<ul>
{snap.todos.map((todo, index) => (
<li key={index}>
<input
type="checkbox"
checked={todo.done}
onChange={() => (state.todos[index].done = !todo.done)}
/>
{todo.text}
</li>
))}
</ul>
</div>
);
}
export default App;
```
**Step 8:** Managing Derived State
Valtio allows you to create derived state using JavaScript getters. This can be useful for computed properties.
**Add a computed property to App.jsx:**
```
const state = proxy({
count: 0,
todos: [],
get completedTodos() {
return this.todos.filter(todo => todo.done).length;
},
});
function App() {
const snap = useSnapshot(state);
const addTodo = () => {
const newTodo = prompt('Enter a new to-do:');
if (newTodo) {
state.todos.push({ text: newTodo, done: false });
}
};
return (
<div>
<h1>Count: {snap.count}</h1>
<button onClick={() => state.count++}>Increment</button>
<button onClick={() => state.count--}>Decrement</button>
<hr />
<h2>To-Do List</h2>
<button onClick={addTodo}>Add To-Do</button>
<ul>
{snap.todos.map((todo, index) => (
<li key={index}>
<input
type="checkbox"
checked={todo.done}
onChange={() => (state.todos[index].done = !todo.done)}
/>
{todo.text}
</li>
))}
</ul>
<p>Completed Todos: {snap.completedTodos}</p>
</div>
);
}
export default App;
```
**Testing a Valtio-powered Component**
Let’s consider a simple example:
```
import { proxy, useSnapshot } from 'valtio';
const state = proxy({
count: 0,
increment() {
state.count++;
},
});
function Counter() {
const snap = useSnapshot(state);
return (
<div>
<p>Count: {snap.count}</p>
<button onClick={state.increment}>Increment</button>
</div>
);
}
```
Now, let’s write a unit test for it:
```
import { render, screen, fireEvent } from '@testing-library/react';
import { proxy } from 'valtio';
import Counter from './Counter';
test('renders counter and increments count on button click', () => {
// Create a proxy for testing
const state = proxy({ count: 0 });
// Render the component with the test proxy
render(<Counter state={state} />);
// Get references to the elements
const countElement = screen.getByText(/Count: 0/i);
const buttonElement = screen.getByRole('button');
// Assert initial state
expect(countElement).toBeInTheDocument();
expect(countElement.textContent).toBe('Count: 0');
// Simulate button click
fireEvent.click(buttonElement);
// Assert updated state
expect(countElement.textContent).toBe('Count: 1');
});
```
**Key Points:**
**Create a Test Proxy**: Instead of using your production state, create a simple proxy specifically for testing.
**Provide the Proxy to Your Component**: Pass the state proxy as a prop to your Counter component.
**Test User Interactions**: Use RTL’s fireEvent to simulate user actions (like button clicks) and then assert that the UI updates as expected.
**Best Practices**:
**Focus on Behavior**: Test how the component behaves when its underlying Valtio state changes, rather than testing the internals of Valtio itself.
**Isolate Components**: If your component relies on other components that use Valtio, consider mocking those dependencies to keep your tests focused.
**Test Edge Cases**: Test scenarios like initial state, state updates, and error handling.
**Leverage RTL Utilities**: Utilize the full power of React Testing Library’s screen object and query methods for interacting with and asserting on your component's DOM.
**Detailed Comparison Table**:
**A closer look at how Valtio Differs from Other Libraries()**:
1. Reactive State Management
**Valtio**: Valtio uses JavaScript Proxies to create reactive state objects. This means that any changes to the state automatically trigger re-renders of the components that use that state, without the need for explicit subscriptions or actions.
**Other Libraries**:
**Redux**: Uses a more traditional approach with actions and reducers to manage state changes. Requires boilerplate code for actions, reducers, and dispatching.
**MobX**: Uses observables to track state changes and reactions. While it provides automatic reactivity, it requires decorators or specific methods to define observables and actions.
**Zustand**: Uses hooks to manage state and provides a simple API. Reactivity is handled manually through hooks.
**Jotai**: This library uses atoms and hooks to manage state with a minimal API. Atom updates and hooks achieve reactivity.
2. API Simplicity and Minimalism
**Valtio**: Offers a very minimalistic API. The primary functions are proxy for creating reactive state objects and useSnapshot for using state within components.
**Other Libraries**:
**Redux**: The API is extensive, involving actions, reducers, middleware, and selectors. It can be overwhelming for new users due to its verbosity.
**MobX**: While powerful, MobX’s API includes observables, actions, reactions, and computed values, which can be complex to understand and use effectively.
**Zustand**: Provides a straightforward API but requires manual reactivity management through hooks.
**Jotai**: Also offers a minimal API with atoms and hooks, but the concept of atoms may introduce a slight learning curve.
3. Performance and Granular Updates
**Valtio**: Valtio’s Proxy-based reactivity allows for fine-grained updates. Only the parts of the state that change will trigger re-renders, optimizing performance.
**Other Libraries**:
**Redux**: State updates can be optimized with selectors and middleware, but all updates go through the central store, which can introduce performance bottlenecks if not managed carefully.
**MobX**: Provides fine-grained reactivity through observables and reactions, making it very performant in handling complex state changes.
**Zustand**: Achieves good performance through hook-based state management but requires manual optimization for fine-grained updates.
**Jotai**: Allows for granular updates by splitting state into atoms, but managing many atoms can become complex.
4. TypeScript Support
**Valtio**: Has excellent TypeScript support, making it easy to define and use type-safe state objects.
**Other Libraries**:
- ** Redux**: Provides strong TypeScript support, but the extensive boilerplate can make type definitions cumbersome.
**MobX**: Good TypeScript support, though decorators can complicate type definitions.
- ** Zustand**: Offers good TypeScript support with simple type definitions.
- ** Jotai**: Provides strong TypeScript support with straightforward type-safe atoms.
**Conclusion:**
Valtio’s simplicity and reactivity make it an excellent choice for state management in React applications. By combining Valtio with React Testing Library and Jest, you can ensure your state management logic is robust and reliable. This article has demonstrated how to set up and write unit tests for both synchronous and asynchronous Valtio states, providing a solid foundation for testing your Valtio-based state management.

1,921,920 | Exploring JavaScript Array Methods with Examples | JavaScript arrays are versatile and offer a wide range of built-in methods to manipulate, iterate,... | 0 | 2024-07-13T04:56:40 | https://dev.to/suleman_ahmed_rajput/exploring-javascript-array-methods-with-examples-3p90 | javascript, webdev, beginners |
JavaScript arrays are versatile and offer a wide range of built-in methods to manipulate, iterate, and manage data efficiently. Understanding these methods is crucial for effective programming. Let's delve into some commonly used array methods with practical examples.
## Array Methods
- **push():** Adds one or more elements to the end of an array and returns the new length of the array.
```javascript
let fruits = ['apple', 'banana'];
fruits.push('orange'); // returns 3 (new length of array)
console.log(fruits); // Output: ['apple', 'banana', 'orange']
```
- **pop():** Removes the last element from an array and returns that element.
``` javascript
let fruits = ['apple', 'banana', 'orange'];
let lastFruit = fruits.pop(); // returns 'orange'
console.log(fruits); // Output: ['apple', 'banana']
console.log(lastFruit); // Output: 'orange'
```
- **shift():** Removes the first element from an array and returns that removed element.
``` javascript
let fruits = ['apple', 'banana', 'orange'];
let firstFruit = fruits.shift(); // returns 'apple'
console.log(fruits); // Output: ['banana', 'orange']
console.log(firstFruit); // Output: 'apple'
```
- **unshift():** Adds one or more elements to the beginning of an array and returns the new length of the array.
``` javascript
let fruits = ['banana', 'orange'];
fruits.unshift('apple'); // returns 3 (new length of array)
console.log(fruits); // Output: ['apple', 'banana', 'orange']
```
- **forEach():** Executes a provided function once for each array element.
``` javascript
let numbers = [1, 2, 3];
numbers.forEach(function(num) {
console.log(num * 2); // Output: 2, 4, 6
});
```
- **map():** Creates a new array populated with the results of calling a provided function on every element in the calling array.
``` javascript
let numbers = [1, 2, 3];
let doubled = numbers.map(function(num) {
return num * 2;
});
console.log(doubled); // Output: [2, 4, 6]
```
- **filter():** Creates a new array with all elements that pass the test implemented by the provided function.
``` javascript
let numbers = [1, 2, 3, 4, 5];
let evens = numbers.filter(function(num) {
return num % 2 === 0;
});
console.log(evens); // Output: [2, 4]
```
- **find():** Returns the first element in the array that satisfies the provided testing function.
```javascript
let numbers = [10, 20, 30, 40, 50];
let found = numbers.find(function(num) {
return num > 25;
});
console.log(found); // Output: 30
```
- **reduce():** Applies a function against an accumulator and each element in the array (from left to right) to reduce it to a single value.
```javascript
let numbers = [1, 2, 3, 4, 5];
let sum = numbers.reduce(function(acc, current) {
return acc + current;
}, 0);
console.log(sum); // Output: 15 (1 + 2 + 3 + 4 + 5)
```
- **indexOf():** Returns the first index at which a given element can be found in the array, or -1 if it is not present.
```javascript
let fruits = ['apple', 'banana', 'orange', 'apple'];
let index = fruits.indexOf('apple'); // returns 0
console.log(index); // Output: 0
```
- **lastIndexOf():** Returns the last index at which a given element can be found in the array, or -1 if it is not present.
```javascript
let fruits = ['apple', 'banana', 'orange', 'apple'];
let lastIndex = fruits.lastIndexOf('apple'); // returns 3
console.log(lastIndex); // Output: 3
```
These array methods are fundamental tools for manipulating data structures in JavaScript efficiently. By mastering these methods, you'll gain a powerful toolkit for handling arrays in various programming scenarios.

Isso é... | 0 | 2024-07-13T06:15:36 | https://dev.to/devsjavagirls/declarando-variaveis-de-controle-de-laco-dentro-do-for-3kg5 | java | **Conceito**
- É possível declarar a variável de controle diretamente na declaração do laço for.
- Isso é útil quando a variável só é necessária dentro do próprio laço.
**Vantagens**
- Melhora a legibilidade e organização do código.
- Limita o escopo da variável ao laço, reduzindo a possibilidade de erros.
**Exemplo**
- O programa a seguir calcula a soma e o fatorial dos números de 1 a 5, declarando a variável de controle i dentro do for:
```
// Declara a variável de controle de laço dentro de for.
class ForVar {
public static void main(String args[]) {
int sum = 0;
int fact = 1;
// calcula o fatorial dos números até 5
for(int i = 1; i <= 5; i++) {
sum += i; // i é conhecida em todo o laço
fact *= i;
}
// mas não é conhecida aqui
System.out.println("Sum is " + sum);
System.out.println("Factorial is " + fact);
}
}
```
**Importante**
O escopo da variável declarada dentro do for é limitado ao laço.
Fora do for, a variável não é acessível:
```
// Declaração correta dentro do for
for (int i = 0; i < 5; i++) {
System.out.println(i); // i é acessível aqui
}
// System.out.println(i); // Erro: i não é conhecida fora do laço
```
**Uso e Limitações**
Declare a variável dentro do for quando ela não for necessária fora do laço.
Se precisar usar a variável fora do laço, declare-a antes do for:
```
int i; // Declarada fora do laço
for (i = 0; i < 5; i++) {
System.out.println(i);
}
// i é acessível aqui
System.out.println("Final value of i: " + i);
```

For example, some of the most advanced optical cable connectors available today have built-in safety features that help to prevent accidental unplugging and protect 1 core fiber optic cable equipment from potential damage, providing a safe environment for every operation in data center.
Safety First
The security of data centers comes first. Optical cable connectors are the trusted from of connection for safety, offering a reliable (always), rock solid plugged in data transfer side effect free way to use your gear without loosing any electrical signal and risking damaging or more importantly DATA LOSS! Optical cable fittings, meanwhile, offer a low fire hazard -- unlike primitive copper fittingsthey are cool to the touch. This is part of the reason why data centers can run modern solutions that are both high-performance and highly protection while still being safe.
Using Optical Cable Fittings
Optical Cable Fittings Explained This is an easy breakdown of their world and demands plain expertise in network connectivity. Start by making sure that optical cable and fitting are compatible to avoid any interruptions along the way. Then line up the cable end with fitting and slowly insert it into you hear a nice click indicating that its securely attached. The optical cable fitting will snugly secure the cabling and make sure it is held in place so that data can be transferred without a single breakdown or disconnection.
Quality Service
Behind every data center in the world is a dedication to provide best-of-breed service. Optical cable fittings are the best example of this dedication in which a strong and long-lasting connection is provided for transferring data through proper channelizing across your occupying network. When buying fiber optic cable accessories, it is necessary to select professional supplier which provides 16 core fiber optic cable high quality products and after-sale service. The result is a better experience and best performance in the data center.
How And Where Optical Cable Fittings Are Used?
Nonetheless, the prevalence of optical cable fittings powered by CMP is indicative to their mass applications within data centers. These fittings bridge the gap between servers and storage devices, networking equipment, etc. thereby enhancing connectivity and simplifying operations as well But beyond the speed, improved safety and ease of use make them a sledgehammer component in any data center build: They can easily handle an eclectic selection of uses.
So, to sum up-you cannot ignore the importance of fiber optic connector in data center world. Organizations looking to improve their connectability and operational efficiency should look at using thin clients before they get outdated (if it has not happened yet). Selecting a value-added vendor which emphasizes quality and supportive customer experience can unlock all the advantages an operator seeks through optical cable fittings to ensure nonstop networking. | jdifb_vdjdvd_a788eb5f5878 |

1,921,931 | Getting a Grip on the Singleton Pattern in Software Design: Ensuring a Single Instance | Around the globe design patterns are being widely accepted by software developers which in turn... | 0 | 2024-07-13T05:08:06 | https://dev.to/azizurrahaman/getting-a-grip-on-the-singleton-pattern-in-software-design-ensuring-a-single-instance-535i |
Around the globe design patterns are being widely accepted by software developers which in turn makes it a fundamental part of the software development process.
It cannot be ignored that design patterns are the must-have tool for solving software programming problems and moreover, best practices for the writing of a maintainable and robust code have been developed.
What makes the Singleton Pattern smart and convenient is that it solves the issue with global state access and the lack of a clear identification of the class instance.
A concrete example of the Singleton Pattern as an object-oriented programming (OOP) concept is that it is a simplifying method. In this article, we shall go through the basics of the Singleton Pattern, some of its main features, and finally, we will show you the various programming languages that you can implement the Singleton Pattern using.
**What is the Singleton Pattern?**
The Singleton pattern is a creational design pattern, which effectively ensures that a class has only one instance and serves as a global point of access to that instance. It’s a simple yet powerful concept in object-oriented programming, widely used for managing shared resources and coordinating actions across a system.
**Key Characteristics:**
- Single instance: The class allows only one instance to be created.
- Global access: Provides a method to access the instance from anywhere in the application.
- Lazy initialization: The instance is typically created only when it’s first requested.
- Reduced Namespace Pollution: By using a singleton, you avoid creating a global variable.
- Resource Management: Useful for managing shared resources like database connections or configuration settings.
- Cross-System Coordination: It is useful for coordinating actions across a system, such as managing a configuration object, logging, or managing a connection pool.
**Implementation:**
Here’s a basic implementation in Dart:
```
class Singleton{
// private static variable
static Singleton _instance = Singleton._internal();
// private constructor
Singleton._internal();
// static method to get the instance
static Singleton get instance => _instance;
// public variable
String name = 'Singleton';
}
```
Here’s a basic implementation in Python:
```
class Singleton:
_instance = None
def __new__(cls):
if cls._instance is None:
cls._instance = super().__new__(cls)
return cls._instance
def some_business_logic(self):
# ...
```
Here’s a basic implementation in Java:
```
public class Singleton {
private static Singleton instance;
private Singleton() {
// private constructor to prevent instantiation
}
public static Singleton getInstance() {
if (instance == null) {
instance = new Singleton();
}
return instance;
}
}
```
Here’s a basic implementation in JavaScript:
```
class Singleton {
constructor() {
if (!Singleton.instance) {
Singleton.instance = this;
}
return Singleton.instance;
}
}
// Usage
const instance1 = new Singleton();
const instance2 = new Singleton();
console.log(instance1 === instance2); // true
```
**Use Cases**
- Database connections
- Configuration managers
- Logging services
- Thread pools
**Advantages**
- Ensures a single instance, saving memory
- Provides a global access point
- Allows lazy initialization
**Disadvantages**
- Can make unit testing more difficult
- Violates the Single Responsibility Principle
- Can be overused, leading to tight coupling
**Best Practices**
- Use Singletons sparingly and only when truly necessary
- Consider alternatives like dependency injection for better testability
- Ensure thread safety in multi-threaded environments
The Singleton pattern, which can be helpful in some cases, should be applied with caution. Before you start implementing this pattern, you should always analyze the unique requirements of your application and possible future requirements. | azizurrahaman | |
