## Introduction to domain events
**Definition of domain events:**
Domain events are events that occur in a specific area or domain and are important for the business logic of an application. They represent significant state changes or activities within the system. In contrast to system-wide events, which can affect the entire application, domain events are closely linked to the specific domain or specialist area of your application.
**Importance of domain events in software development:**
Domain events play a crucial role in the implementation of domain-driven design (DDD), an approach to developing complex software applications that focuses on the domain and its rules. They enable the mapping of real processes and events in the software and support a clearly structured and modularized architecture.
**Why are domain events important?**
Domain events offer several advantages, including:
- Decoupling of components:
By using domain events, different parts of your application can work independently of each other as they only communicate via events without having to access each other directly.
- Traceability and auditing:
Domain Events serve as a log of important events in your application, facilitating traceability of activities and providing the ability to meet auditing and compliance requirements.
- Increased flexibility and extensibility:
By using Domain Events, your application can be made more flexible and extensible as changes in the domain can be implemented more easily and existing functionality can be modified without affecting other parts of the application.
## Advantages of domain events
**Improvement in modularity and scalability:**
Using domain events improves the modularity of your application, as individual components are loosely coupled and can work independently of each other. This also facilitates scalability, as you can add or remove individual components as required without significantly changing the overall structure of your application.
**Decoupling of domain logic and infrastructure:**
Domain events support the separation of domain logic and infrastructure by ensuring that your domain objects have no direct dependencies on external systems or frameworks. This leads to a cleaner and more maintainable code base.
**Support for domain-driven design (DDD):**
Domain events are a core element of domain-driven design and enable you to map the technical language of your domain directly in your software. This promotes a common understanding between developers and domain experts and leads to a better alignment of the software with the real requirements of your domain.
## Implementation of domain events
**Identification of relevant events in the domain:**
Before you can implement domain events, it is important to identify the relevant events in your domain. These events should represent significant state changes or activities within your application that are of interest to other parts of the system.
**Creation of event classes and interfaces:**
For each domain event identified, you should create a corresponding event class that contains the relevant information about the event. These classes can also implement interfaces to enable consistent handling and processing of events.
**Publication and subscription of domain events:**
To use domain events in your application, you need to implement mechanisms for publishing and subscribing to events. This can be done, for example, by using event buses or brokers that allow different parts of your application to react to events and act accordingly.
## Integration of domain events in applications
**Use of event buses or brokers:**
To integrate domain events in your application, you can use event buses or brokers. These components enable the central administration and distribution of events to the corresponding recipients within your application. Examples of event busses are RabbitMQ, Kafka or simple in-memory event busses.
**Handling of errors and transaction limits:**
When integrating domain events, it is important to consider the handling of errors and the consideration of transaction boundaries. You should ensure that events are processed atomically and that no data inconsistencies occur, especially in the case of failed transactions.
**Testing strategies for domain events:**
For reliable integration of domain events, it is essential to develop appropriate testing strategies. This includes testing event generation, publication and processing as well as testing scenarios with faulty event processing to ensure the robustness of your application.
## Practical application of domain events
**Example application: e-commerce order processing:**
To illustrate the use of domain events in a practical application, let’s look at an example from the field of e-commerce: order processing. In this scenario, various events can occur that can be represented by domain events, e.g:
- “Order placed”
- “Order paid”
- “Order shipped”
- “Order canceled”
**Triggering events for order status changes:**
When the status of an order changes, e.g. from “placed” to “paid”, corresponding domain events can be triggered and published. These events can be subscribed to by other parts of the application in order to react to changes and perform corresponding actions, e.g. updating the stock or sending a confirmation email to the customer.
**Respond to events to update other components:**
Domain events allow different components of your application to react to state changes and communicate with each other without having direct dependencies. This improves the flexibility and extensibility of your application and promotes a modular architecture.
## Best practices and recommendations
**Naming conventions for events:**
It is advisable to use consistent naming conventions for your domain events to ensure uniform and easy-to-understand naming. Use meaningful and precise names that clearly reflect the content and meaning of the event.
**Documentation of events and their payloads:**
To facilitate the use of domain events and encourage collaboration between developers, it is important to document events and their payloads appropriately. Describe the purpose of each event as well as the data fields it contains and their meaning.
**Monitoring and logging of event-based operations:**
To ensure the reliability and performance of your application, you should monitor and log event-based operations appropriately. This includes logging event publications, receptions and processing as well as monitoring system metrics and error messages.
By applying these best practices, you can improve the effectiveness and robustness of your application and ensure that domain events are used efficiently and reliably.

{
Console.WriteLine($"New order received: ID={e.OrderId}, Date={e.OrderDate}, Customer={e.CustomerName}");
// Further actions could be carried out here, e.g., send a confirmation email
}
}
```
## DomainEvents with MediatR
```
using MediatR;
using System;
namespace With_MediatR.Events
{
public class OrderPlacedEvent : INotification
{
public long OrderId { get; set; }
public DateTime OrderDate { get; set; }

return Task.CompletedTask;
}
}
}
```
```
using MediatR;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Reflection;
using System.Threading.Tasks;
using With_MediatR.Events;
using With_MediatR.Handlers;
public class Program
{
public static async Task Main(string[] args)
{
try
{
// Configuration and initialisation of MediatR
var serviceProvider = ConfigureServices();
var mediator = serviceProvider.GetRequiredService<IMediator>();
// Place order and trigger event
var orderId = GenerateOrderId();
var orderDate = DateTime.Now;
var customerName = "Walter Hartwell White";
await mediator.Publish(new OrderPlacedEvent(orderId, orderDate, customerName));
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine($"An error occurred: {ex.Message}");
}
}
private static IServiceProvider ConfigureServices()
{
var services = new ServiceCollection();
// Add MediatR

{
// Dynamische Generierung einer Order-ID
return DateTime.Now.Ticks;
}
}
```
## DomaineEvents with MediatR and CQRS Pattern
```
using MediatR;
using Microsoft.Extensions.DependencyInjection;
using System.Reflection;
using With_MediatR_CQRS.Commands;
using With_MediatR_CQRS.EventHandlers;
using With_MediatR_CQRS.Handlers;
using With_MediatR_CQRS.Queries;
using With_MediatR_CQRS.Repositories;
public class Program
{
public static async Task Main(string[] args)
{
// Configuration and initialisation of MediatR
var serviceProvider = ConfigureServices();
var mediator = serviceProvider.GetRequiredService<IMediator>();
// Creation of the command to create a new order
var createOrderCommand = new CreateOrderCommand
{
OrderId = 034059020106036052,
CustomerName = "Walter Hartwell White",
OrderDate = DateTime.Now,
Products = new List<string> { "BlueProduct #1", "BlueProduct #2" }
};
// Call the handler for the command to create a new order
await mediator.Send(createOrderCommand);// [call CreateOrderCommandHandler]
// Creation of the query for orders from a specific customer
var getOrdersQuery = new GetOrdersQuery
{
CustomerName = "Walter Hartwell White"
};
// Call up handler for querying orders from a specific customer
var orders = await mediator.Send(getOrdersQuery); // [call GetOrdersQueryHandler]
Console.WriteLine($"Number of orders for {getOrdersQuery.CustomerName}: {orders.Count}");
}
private static IServiceProvider ConfigureServices()
{
var services = new ServiceCollection();
//Register repositories and handlers
services.AddTransient<OrderRepository>();
services.AddTransient<CreateOrderCommandHandler>();
services.AddTransient<OrderCreatedEventHandler>();
services.AddTransient<GetOrdersQueryHandler>();
// Add MediatR
services.AddMediatR(cfg => cfg.RegisterServicesFromAssembly(Assembly.GetExecutingAssembly()));
return services.BuildServiceProvider();
}
}
```
```
using MediatR;
using With_MediatR_CQRS.Classes;
namespace With_MediatR_CQRS.Queries;
public class GetOrdersQuery : IRequest<List<Order>>
{
public string CustomerName { get; set; }
}
```
```
using MediatR;
using With_MediatR_CQRS.Commands;
using With_MediatR_CQRS.Events;
namespace With_MediatR_CQRS.Handlers;
public class CreateOrderCommandHandler : IRequestHandler<CreateOrderCommand>
{
private readonly IMediator _mediator;
public CreateOrderCommandHandler(IMediator mediator)
{
_mediator = mediator;
}
public async Task Handle(CreateOrderCommand request, CancellationToken cancellationToken)
{
// This is where the logic for creating a new order would take place
Console.WriteLine($"New order created at {request.OrderDate}: ID={request.OrderId}, Customer={request.CustomerName}");
// Triggering the domain event "Order created"
await _mediator.Publish(new OrderCreatedEvent(request.OrderId, request.CustomerName, request.OrderDate, request.Products));
}
}
```
```
using MediatR;
namespace With_MediatR_CQRS.Events;
public class OrderCreatedEvent : INotification
{
public long OrderId { get; }
public string CustomerName { get; }
public DateTime OrderDate { get; set; }
public List<string> Products { get; }
public OrderCreatedEvent(long orderId, string customerName,DateTime orderDate, List<string> products)
{
OrderId = orderId;
CustomerName = customerName;
OrderDate = orderDate;
Products = products;
}
}
```
```
using MediatR;
using With_MediatR_CQRS.Classes;
using With_MediatR_CQRS.Events;
using With_MediatR_CQRS.Repositories;
namespace With_MediatR_CQRS.EventHandlers;
public class OrderCreatedEventHandler : INotificationHandler<OrderCreatedEvent>
{
private readonly OrderRepository _orderRepository;
public OrderCreatedEventHandler(OrderRepository orderRepository)
{
_orderRepository = orderRepository;
}
public Task Handle(OrderCreatedEvent notification, CancellationToken cancellationToken)
{
// For this example, we simulate the receipt of the order 15 minutes after the order was placed
Console.WriteLine($"New order received at {DateTime.Now.AddMinutes(+15)}: ID={notification.OrderId}, Customer={notification.CustomerName}");
foreach (var product in notification.Products)
{
Console.WriteLine($"Product added: {product}");
}
// Save the order in the repository
_orderRepository.Add(new Order(notification.OrderId, notification.CustomerName, notification.OrderDate, notification.Products));
return Task.CompletedTask;
}
}
```
```
using MediatR;
namespace With_MediatR_CQRS.Commands;
public class CreateOrderCommand : IRequest
{
public long OrderId { get; set; }
public string CustomerName { get; set; }
public DateTime OrderDate { get; set; }
public List<string> Products { get; set; }
}
namespace With_MediatR_CQRS.Classes;
public class Order
{
public long OrderId { get; }
public string CustomerName { get; }
public DateTime OrderDate { get; set; }
public List<string> Products { get; }
public Order(long orderId, string customerName, DateTime orderDate, List<string> products)
{
OrderId = orderId;
CustomerName = customerName;
OrderDate = orderDate;
Products = products;
}
}
```
In this example, MediatR is used to manage the commands and events. The **CreateOrderCommandHandler** is responsible for processing the command to create an order and then triggers the domain event **Order created**. The **_OrderCreatedEventHandler_** reacts to this event and executes corresponding actions.
This example shows how CQRS and domain events can be used together with MediatR in an application.

1,908,711 | Styling Buttons with styled-jsx in Next.js | Learn how to style buttons using styled-jsx in the Next.js framework to enhance the UI of your web projects. | 0 | 2024-07-02T10:00:39 | https://dev.to/itselftools/styling-buttons-with-styled-jsx-in-nextjs-29fb | javascript, css, nextjs, webdev |
In our ongoing journey at [itselftools.com](https://itselftools.com), where we've developed over 30 projects using Next.js and Firebase, we've encountered and implemented a variety of ways to style applications effectively. One of the tools we frequently utilize in our Next.js projects for component-level styling is `styled-jsx`. This powerful CSS-in-JS library is tailor-made for Next.js and provides scoped styles without sacrificing performance. In this article, we will explore how to style a button using `styled-jsx`.
## Code Explanation
To understand how `styled-jsx` works and how it can be applied to style a simple UI element like a button, let's look at the following code snippet:
```jsx
import StyleSheet from 'styled-jsx/css'
export const buttonStyle = StyleSheet\
button {
background-color: #0070f3;
border: none;
color: white;
padding: 8px 16px;
border-radius: 4px;
cursor: pointer;
}
button:hover {
background-color: #0056b3;
}
```
### Breakdown
- **Importing styled-jsx**: We start by importing `StyleSheet` from `styled-jsx/css`, which is a module dedicated to defining scoped CSS styles.
- **Defining Styles**: The `buttonStyle` constant is where the CSS for a button is defined. Here’s what each property does:
- `background-color`: Sets the button's default background color to a vivid blue (#0070f3).
- `border`: Removes any border from the button, making it look cleaner.
- `color`: Ensures that the text inside the button is white for better readability against the blue background.
- `padding`: Adds padding inside the button for a better user interface.
- `border-radius`: Rounds the corners of the button to give it a modern look.
- `cursor`: Changes the cursor to a pointer when hovering over the button, indicating it's clickable.
- `:hover`: A pseudo-class that changes the button's background color to a darker blue (#0056b1) when the mouse hovers over it.
## Practical Application
Using styled-jsx for styling in Next.js not only helps in keeping styles scoped to the component but also precompiles styles to minimize runtime overhead. When you use `styled-jsx`, styles are injected at runtime and are scoped automatically to the markup rendering them, ensuring that styles do not leak to other elements of the application.
## Conclusion
Styled-jsx provides a robust solution for managing CSS in your Next.js apps, ensuring that each component maintains its unique style sandbox. If you're interested in seeing `styled-jsx` in action, consider visiting some of our applications such as utilizing [disposable email services](https://tempmailmax.com), exploring [online word searching tools](https://find-words.com), or experimenting with [tools for screen recording](https://online-screen-recorder.com). Each of these tools leverages modern web technologies to enhance user experience and functionality.

1,908,636 | Backtracking, Design and Analysis of Algorithms | Fundamentals of Backtracking Definition and Importance of... | 0 | 2024-07-02T09:57:15 | https://dev.to/harshm03/backtracking-design-and-analysis-of-algorithms-4ooj | algorithms, coding, programming, design | ### Fundamentals of Backtracking
#### Definition and Importance of Backtracking
**Definition:**
Backtracking is a general algorithmic technique that incrementally builds candidates for the solution to a problem and abandons a candidate (backtracks) as soon as it determines that the candidate cannot possibly be completed to a valid solution. It is often used for solving constraint satisfaction problems, where the goal is to find a solution that satisfies a set of constraints.
**Importance:**
Backtracking is important because it provides a systematic way to explore all possible solutions to a problem. It is particularly useful in situations where:
- The problem requires finding all possible solutions.
- The problem involves constraints that need to be satisfied.
- Other algorithmic techniques, like dynamic programming or greedy algorithms, are not applicable or less efficient.
#### Basic Principles and Concepts
1. **Candidate Solution Construction:**
- Start with an empty partial solution.
- Gradually add components to this partial solution until it becomes a complete solution.
2. **Feasibility Check:**
- After adding each new component, check if the partial solution is still feasible (i.e., it still has the potential to lead to a valid complete solution).
- If it is not feasible, backtrack by removing the last added component and try the next possibility.
3. **Completeness Check:**
- Once a partial solution becomes a complete solution, check if it meets all the criteria of the problem.
4. **Backtracking:**
- If a partial solution cannot be extended to a complete valid solution, discard it and backtrack to the previous step to try another possibility.
5. **Recursive Structure:**
- Backtracking algorithms are often implemented using recursion, where each recursive call represents a step in the construction of the solution.
#### Comparison with Other Algorithmic Techniques
**1. Brute Force:**
- **Brute Force** algorithms try all possible solutions without any form of optimization. They guarantee finding a solution if it exists but are typically inefficient for large problems.
- **Comparison:** Backtracking can be seen as a refined brute force approach that eliminates many unnecessary possibilities early on through feasibility checks.
**2. Greedy Algorithms:**
- **Greedy Algorithms** build a solution step by step, always choosing the next step that offers the most immediate benefit. They are generally faster but do not always guarantee an optimal solution.
- **Comparison:** Backtracking, unlike greedy algorithms, explores all potential solutions and thus can guarantee finding an optimal solution, though it is usually slower.
**3. Dynamic Programming (DP):**
- **Dynamic Programming** solves problems by breaking them down into simpler subproblems and storing the solutions to these subproblems to avoid redundant calculations.
- **Comparison:** Backtracking is more straightforward and generally easier to implement for constraint satisfaction problems, but DP is more efficient for optimization problems with overlapping subproblems and optimal substructure.
### Recursive Backtracking
#### Understanding Recursion in the Context of Backtracking
**Recursion** is a fundamental concept in computer science where a function calls itself to solve a problem. In the context of backtracking, recursion helps explore all possible configurations of a solution space by breaking down the problem into smaller subproblems.
**Backtracking** leverages recursion to build potential solutions incrementally and explore them in a depth-first manner. The recursive function keeps track of the current state (partial solution) and decides whether to proceed with the current path or backtrack to explore other possibilities.
#### Base Case and Recursive Case
**Base Case:**
- The base case is the condition under which the recursive function stops calling itself. In backtracking, the base case typically occurs when a complete solution has been constructed or when it is determined that no further progress can lead to a valid solution.
- Example: In generating permutations, the base case is when the length of the current permutation equals the length of the input set.
**Recursive Case:**
- The recursive case is the part of the function where the function calls itself with modified parameters to explore further possibilities.
- Example: In generating permutations, the recursive case involves choosing an element, adding it to the current permutation, and then recursively generating permutations of the remaining elements.
### Example for Backtracking
Backtracking is a recursive algorithmic technique used for solving problems incrementally by trying out possible solutions and eliminating those that fail to meet the criteria at any point of time. This approach is particularly useful in constraint satisfaction problems, combinatorial optimization problems, and puzzle solving.
#### Combinations
To generate all combinations of a given set of elements, we can use backtracking. Here’s a C++ implementation:
```cpp
#include <iostream>
#include <vector>
using namespace std;
// Recursive function to generate all combinations
void generateCombinations(vector<int>& elements, int start, vector<int>& path, vector<vector<int>>& result) {
result.push_back(path); // Add the current combination to the result
for (int i = start; i < elements.size(); ++i) {
path.push_back(elements[i]); // Choose the current element
generateCombinations(elements, i + 1, path, result); // Explore further combinations
path.pop_back(); // Backtrack
}
}
vector<vector<int>> getCombinations(vector<int>& elements) {
vector<vector<int>> result;
vector<int> path;
generateCombinations(elements, 0, path, result);
return result;
}
int main() {
vector<int> elements = {1, 2, 3};
vector<vector<int>> combinations = getCombinations(elements);
cout << "Combinations:\n";
for (auto& combination : combinations) {
cout << "{ ";
for (int num : combination) {
cout << num << " ";
}
cout << "}\n";
}
return 0;
}
```
#### Permutations
To generate all permutations of a given set of elements, we can also use backtracking. Here’s a C++ implementation:
```cpp
#include <iostream>
#include <vector>
using namespace std;
// Recursive function to generate all permutations
void generatePermutations(vector<int>& elements, vector<bool>& chosen, vector<int>& path, vector<vector<int>>& result) {
if (path.size() == elements.size()) {
result.push_back(path); // Base case: Add the current permutation to the result
return;
}
for (int i = 0; i < elements.size(); ++i) {
if (chosen[i]) continue;
chosen[i] = true; // Mark the element as chosen
path.push_back(elements[i]); // Choose the current element
generatePermutations(elements, chosen, path, result); // Explore further permutations
path.pop_back(); // Backtrack
chosen[i] = false; // Unmark the element
}
}
vector<vector<int>> getPermutations(vector<int>& elements) {
vector<vector<int>> result;
vector<bool> chosen(elements.size(), false);
vector<int> path;
generatePermutations(elements, chosen, path, result);
return result;
}
int main() {
vector<int> elements = {1, 2, 3};
vector<vector<int>> permutations = getPermutations(elements);
cout << "Permutations:\n";
for (auto& permutation : permutations) {
cout << "{ ";
for (int num : permutation) {
cout << num << " ";
}
cout << "}\n";
}
return 0;
}
```
#### Knapsack Problem (Maximize Profit)
The Knapsack problem can also be solved using backtracking. The goal is to find the maximum value of items that can be put into a knapsack with a given weight capacity. Here’s a C++ implementation:
```cpp
#include <iostream>
#include <vector>
using namespace std;
// Recursive function to solve the knapsack problem using backtracking
void knapsackBacktracking(vector<int>& weights, vector<int>& values, int maxWeight, int index, int currentWeight, int currentValue, int& maxValue) {
// Base case: If we have considered all items
if (index == weights.size()) {
maxValue = max(maxValue, currentValue); // Update the maximum value if the current value is greater
return;
}
// Case 1: Exclude the current item and move to the next item
knapsackBacktracking(weights, values, maxWeight, index + 1, currentWeight, currentValue, maxValue);
// Case 2: Include the current item if it does not exceed the maximum weight
if (currentWeight + weights[index] <= maxWeight) {
knapsackBacktracking(weights, values, maxWeight, index + 1, currentWeight + weights[index], currentValue + values[index], maxValue);
}

int maxValue = 0;
knapsackBacktracking(weights, values, maxWeight, 0, 0, 0, maxValue);
cout << "Maximum value that can be obtained: " << maxValue << endl;
return 0;
}
```
#### Knapsack Problem (All Subsets with Maximum Value)
Finding all subsets of items that yield the maximum profit without exceeding the knapsack capacity involves backtracking.
```cpp
#include <iostream>
#include <vector>
using namespace std;
// Function to solve 0/1 Knapsack problem and find all subsets with maximum profit
void knapsackAllMaxValueSubsets(vector<int>& weights, vector<int>& profits, int capacity, int index, int currentWeight, int currentProfit, int& maxProfit, vector<int>& path, vector<vector<int>>& result) {
// Base case: If all items are considered
if (index == weights.size()) {
if (currentProfit > maxProfit) {
maxProfit = currentProfit; // Update maximum profit if current profit is greater
result.clear(); // Clear previous subsets with lesser profit
}
if (currentProfit == maxProfit) {
result.push_back(path); // Add the current subset to the result
}
return;
}
// Case 1: Exclude the current item and move to the next item
knapsackAllMaxValueSubsets(weights, profits, capacity, index + 1, currentWeight, currentProfit, maxProfit, path, result);
// Case 2: Include the current item if it does not exceed the knapsack capacity
if (currentWeight + weights[index] <= capacity) {
path.push_back(index); // Include the index (item) in the current subset
knapsackAllMaxValueSubsets(weights, profits, capacity, index + 1, currentWeight + weights[index], currentProfit + profits[index], maxProfit, path, result);
path.pop_back(); // Backtrack
}
}
vector<vector<int>> getAllMaxValueSubsets(vector<int>& weights, vector<int>& profits, int capacity) {
vector<vector<int>> result;
vector<int> path;
int maxProfit = 0;
knapsackAllMaxValueSubsets(weights, profits, capacity, 0, 0, 0, maxProfit, path, result);
return result;
}
int main() {
vector<int> weights = {2, 3, 4, 5};
vector<int> profits = {3, 4, 5, 6};
int capacity = 7;
vector<vector<int>> subsets = getAllMaxValueSubsets(weights, profits, capacity);
cout << "Subsets with maximum profit (" << subsets.size() << " subsets):\n";
for (auto& subset : subsets) {
cout << "{ ";
for (int index : subset) {
cout << index << " ";
}
cout << "}\n";
}
return 0;
}
```
#### Subset Sum Equal to K Problem
Finding all subsets of an array that sum up to a given value K involves exploring all possible subsets of the array.
```cpp
#include <iostream>
#include <vector>
using namespace std;
// Function to find all subsets with sum equal to target using backtracking
void findSubsetsWithSum(vector<int>& nums, int index, int remainingSum, vector<int>& path, vector<vector<int>>& result) {
if (remainingSum == 0) {
result.push_back(path); // Base case: Found a subset with sum equal to target
return;
}
if (remainingSum < 0 || index >= nums.size()) {
return; // Stop recursion if remaining sum is negative or all elements are processed
}
// Include current element
path.push_back(nums[index]);
findSubsetsWithSum(nums, index + 1, remainingSum - nums[index], path, result);
path.pop_back(); // Backtrack
// Exclude current element
findSubsetsWithSum(nums, index + 1, remainingSum, path, result);
}
vector<vector<int>> getSubsetsWithSum(vector<int>& nums, int targetSum) {
vector<vector<int>> result;
vector<int> path;
findSubsetsWithSum(nums, 0, targetSum, path, result);
return result;
}
int main() {
vector<int> nums = {2, 3, 5, 7, 8};
int targetSum = 10;
vector<vector<int>> subsets = getSubsetsWithSum(nums, targetSum);
cout << "Subsets with sum " << targetSum << ":\n";
for (auto& subset : subsets) {
cout << "{ ";
for (int num : subset) {
cout << num << " ";

The last thing any engineer would hope for is to wake up in the early hours of the morning and notice that the software has been down for close to 3hours and all the data in the database is gone due to a cyber-attack 😭.
I am an engineer that places the security of my user's data above anything else.
Therefore, I would not want a user to access the information of another user through some loop-hole found in the security system of my software.

## "What doesn't kill you makes you stronger" - A strong man(probably).
On the 9th of March, 2024, I woke up around 6 am. It was a Saturday so it was unusual for me to be up that early. I said my prayers, picked up my phone and opened WhatsApp. Scrolling through unread messages, a post in my school's Google Developer Student Club group caught my eye. "Django Developer Needed. DM." _Interesting_ I thought. After contemplating for some minutes and going through some moments of self-doubt, I opened the group and messaged the person who posted it.
There was a catch. He said he was in need of a Django Developer with workable knowledge of Bootstrap. _Bruhhh_ I thought. I was a decent Django Developer, but front-end stuff like Bootstrap and CSS? Not my thing. I had a little chat with God on it and I felt cool about it. Taking a deep breath, I told the guy I'd take the gig. We discussed my charge and deadline- I had 24 hours to come up with a working Application. I said "No p", trying to sound confident(even though this was going to be my first paid gig, ever).
There was no power in my hostel, so I packed my Laptop, my charger, Rubik's Cube(for when my brain stops cooperating) and notepad into my bag, and had my bath, drank tea, and headed to the co-working space on campus. While walking, I brainstormed about how the structure of the App would be- team management features, am I using Class Based Views or Function Based Views?, stuff like that. Half-excitement, half-terror tightened my chest. Had I bitten more than I can chew??
I got to the co-working space, paid the fee, took a seat. I booted my Laptop, opened VSCode and just stared. Instead of the usual thrill of building something new, a wave of imposter syndrome washed over me. _Omoo can I actually do this thing?_ I closed my eyes, said a quick prayer and started working. I had a deadline to beat.
The next 15 hours were a blur of coding, troubleshooting, and frantic calls to friends for help and moral support. The only breaks I took were to solve my Cube and eat. I had never worked that long in my short coding life before and the exhilarating feeling I had when I made my final push to GitHub might just be similar to what Neil Armstrong felt when he took that first step on the moon. _One small step for Afebu and a giant leap for his coding career lol_

Last month, I saw a post on X about HNG Internship 11. I had heard stories about how difficult, grueling and rigorous the whole process is. But then I remembered that 24-hour coding marathon. "Well, well, well," I thought, a smile creeping across my face. "Hello hard things, I guess we meet again."

It’s me your friend [Md Taqui Imam](https://mdtaquiimam.vercel.app), and today I’m going to explain a new and exciting hook in React called **useActionState**.
_[Follow me in Github⭐](https://github.com/taqui-786)_
## What is useActionState?
useActionState is a new React hook that helps us update state based on the result of a form action.
It’s like a smart helper that remembers things for us and can change them when we submit a form.
**_[Checkout Official Documentation🚀](https://react.dev/reference/react/useActionState)_**
> Important Note: Right now, useActionState is only available in React’s Canary and experimental channels. To get the most out of it, you’ll need to use a framework that supports React Server Components.
## How to use useActionState?
To use this hook, we first need to import it from React:
import { useActionState } from 'react';
Then, we can use it in our component like this:
```
const [state, formAction, isPending] = useActionState(actionFunction, initialState);
```
**Here’s what each part means:**
**‘state’** is our current form state
**‘formAction’** is a new action we’ll use in our form
**‘actionFunction’** is the function that runs when the form is submitted
**‘initialState’** is the starting value of our state
## When to use useActionState:
Use this hook when you want to update state based on form submissions, especially if you’re using Server Components and want quicker responses.
**Example:**
Let’s make a simple counter form using useActionState:
```
import { useActionState } from "react";
async function increment(previousState, formData) {
return previousState + 1;
}
function StatefulForm() {
const [state, formAction] = useActionState(increment, 0);
return (
<form>
{state}
<button formAction={formAction}>Increment</button>
</form>
);

I was tasked with resolving difficult backend problems on a project which required technical ability skills, Timeframe, Documentation, creativity skill. I recently encountered a difficult backend problem with one educational Institution website and the main root causes of the problem was inefficient database queries, leading to long response times and a degraded user experience.
How I resolve backend problem through this step:
Step 1: Analyzing the system: to detect the bottleneck issues by using monitoring tool and query log to find out queries that might slower the performance of the systems
Step 2: Check Query structure: to check for unnecessary fetch column, table or unmatched table, table field name and table column data type all this slow the performance of the system.
Step 3: Doing Proper indexing for column that most fetched such as Matric Number of a student, Payment Id, courses ID, Faculty ID, Department ID and Result ID. Effective indexing dramatically improved query performance by allowing faster data retrieval.
Step 4: Query refactoring : this removes some query and join queries that fetch data and before combining for the result.
Step 5: Testing such as benchmarking and loading testing to check and validate the system performance.
Step 6: User Feedback: gathering the feedback from users that use it.

Here are some essential JavaScript design patterns that you should know:
## Factory Pattern
The Decorator pattern allows behavior to be added to an individual object, dynamically, without affecting the behavior of other objects from the same class.
**Example:**
`
class Coffee {
cost() {
return 5;
}
}
class MilkDecorator {
constructor(coffee) {
this.coffee = coffee;
}
cost() {
return this.coffee.cost() + 2;
}
}
let coffee = new Coffee();
coffee = new MilkDecorator(coffee);
console.log(coffee.cost()); // 7
`
##Real World Example
###Online Store Product Customization
**Real-World Scenario:** In an online store, customers can customize products by adding features (e.g., extra warranty, gift wrapping). The Decorator pattern allows these features to be added dynamically.
**Define the Base Class:**
```
class Product {
constructor() {
this.price = 100;
}
getPrice() {
return this.price;
}
}
```
**Create Decorator Classes:**
```
class WarrantyDecorator {
constructor(product) {
this.product = product;
}
getPrice() {
return this.product.getPrice() + 20;
}
}
class GiftWrapDecorator {
constructor(product) {
this.product = product;
}
getPrice() {
return this.product.getPrice() + 5;
}
}
```
**Use the Decorator Pattern:**
```
let myProduct = new Product();
myProduct = new WarrantyDecorator(myProduct);
myProduct = new GiftWrapDecorator(myProduct);
console.log(myProduct.getPrice()); // 125 (100 + 20 + 5)
```
##Use Cases of the Decorator Pattern
**1. Adding Responsibilities Dynamically:** When you need to add responsibilities to objects at runtime, the Decorator pattern provides a flexible alternative to subclassing.
**2. Combining Behaviors:** It allows combining several behaviors by applying multiple decorators in a flexible and reusable way.
**3. Enhancing Core Objects:** Useful for enhancing core objects in libraries or frameworks without modifying the original code.
### Conclusion
Understanding these design patterns and knowing when to apply them can greatly improve your coding skills and make you a more effective full-stack developer. They help in creating robust and maintainable code.
Mastering these patterns will help you build better software.
Happy Coding! 🧑💻

1,908,653 | Rendering Videos in the Browser Using WebCodecs API | Every time we mention rendering videos in the browser, we get raised eyebrows and concerns about... | 0 | 2024-07-02T09:08:43 | https://dev.to/rendley/rendering-videos-in-the-browser-using-webcodecs-api-328n | webdev, javascript, programming, frontend | Every time we mention rendering videos in the browser, we get raised eyebrows and concerns about performance. This is for a good reason, mainly because, for a long time, browsers were not capable of doing it and had to use the CPU for decoding and encoding frames.
This bottleneck made companies willing to implement a video editing solution to create two separate systems: a playback mechanism that would run in the browser, allowing users to trim/split videos, apply effects, add text clips, etc., visually, and a backend mechanism that would take the same structure created on the web and recreate it on a server to render it at high speeds.
Such an approach, although it has a faster rendering time, has disadvantages, such as:
- All the clips should be uploaded to a server for the backend to be able to create the composition.
- All the filters/effects/transitions should also be created through a custom rendering solution.
- The backend should download the clips to create the composition.
- Rendering several videos simultaneously can be very computationally intensive, requiring autoscaling solutions.
- The generated video should be stored on the server for the interface to download the rendered output.
- Users typically upload videos larger than 10MB, so you have to consider network connectivity.
- Cannot create a product that works well on slow networks or offline.
- You have to ensure the composition created on the backend matches the one the user created.
- Working with text is challenging and requires consideration of font families and styles.
- Server providers charge for traffic as well, so you have to keep this in consideration.
## Browser Rendering Steps
Generally, rendering the video in the browser involves several steps:
1. Capture the frame.
2. Encode the frame into a video stream.
3. Repeat until all the frames are captured.
4. Mux the video and audio streams into a container.
The most time-consuming steps in this flow are capturing and encoding the frames.
A simple implementation of capturing video frames could be seeking an [HTMLVideoElement](https://developer.mozilla.org/en-US/docs/Web/API/HTMLVideoElement), rendering the texture into the canvas, and taking a screenshot of the whole composition. The seeking in this case will always try to locate the [I-Frame](<https://en.wikipedia.org/wiki/Video_compression_picture_types#Intra-coded_(I)_frames/slices_(key_frames)>) to paint the result, which is a headache for the browser, even if you increase the seeking time by 1/30 (the FPS) seconds. It's also worth mentioning that switching the tabs while rendering happens will pause the video player and cause the final video to have missing sections because browsers have underlying optimizations to ensure good performance.
Regarding encoding, the common solution would be to use the WASM build of [FFmpeg](https://ffmpeg.org/). However, it is not possible to start an encoding process and just append the new frames into the stream because the WASM build does not support it at the moment. You would have to temporarily store all the frames in memory (not a good idea) or store a chunk of them, transform them into an encoded video, and repeat the process.
There is a great video from Christopher Chedeau explaining more about the pipeline that goes into encoding a video and the limitations of the browser:
["Video Editing in the Browser" by Christoher Chedeau at #RemixConf 2023 💿](https://www.youtube.com/watch?v=46_9YsHHUEo)
<br />
## WebCodecs API
The good news is that browsers have started adding support for hardware-accelerated video/audio/image encoders and decoders that solve the issues mentioned above - this set of APIs is known as the [WebCodecs API](https://developer.mozilla.org/en-US/docs/Web/API/WebCodecs_API).
For the capturing part, the seeking can now be replaced with decoding the frame using the [VideoDecoder API](https://developer.mozilla.org/en-US/docs/Web/API/VideoDecoder). This is much faster than seeking because the browser doesn’t have to look for [I-Frames](<https://en.wikipedia.org/wiki/Video_compression_picture_types#Intra-coded_(I)_frames/slices_(key_frames)>), [B-Frames](<https://en.wikipedia.org/wiki/Video_compression_picture_types#Bi-directional_predicted_(B)_frames/slices_(macroblocks)>), and [P-Frames](<https://en.wikipedia.org/wiki/Video_compression_picture_types#Predicted_(P)_frames/slices>) to reconstruct the image. Instead, it can just retrieve what has changed and recreate the texture from that.
Encoding can be done through the [VideoEncoder API](https://developer.mozilla.org/en-US/docs/Web/API/VideoEncoder), which enables appending the video frames directly into the stream without having to store the frames temporarily.
## WebCodecs Considerations
There are things to be aware of when deciding to implement a rendering mechanism with WebCodecs. Here are some hiccups we faced during the process:
- There are no built-in APIs for muxing and demuxing. You have to either use FFmpeg or an alternative library.
- You need additional tooling for identifying the codec string when initializing the decoder. It should follow the pattern described [here](https://aomediacodec.github.io/av1-isobmff/#codecsparam).
- Sometimes, the decoder tells you if it supports a specific configuration only after decoding a few packets, so you have to handle it gracefully.
- WebCodecs is [not supported](https://caniuse.com/?search=webcodecs) in all browsers yet (e.g., Firefox).
- The logs are not always explicit and require you to have additional tooling for debugging.
- When encoding videos, you have to make sure that the devices you are using support the specific resolution. For instance, a 7-year-old Android phone might not be able to encode a video larger than Full HD, and you have to account for that. Also, the encoder doesn’t inform you of this.
- Canvas works with RGB/RGBA color format, but in many cases, the video frames coming from VideoDecoder will be in YUV, requiring you to handle the conversion.
- You can’t get the media/stream info from the video and should use ffmpeg/mp4box.
- You have to identify and handle rotated videos yourself.
- There is a limited number of codecs supported.
## Conclusion
It is possible to render videos in the browser and do it in a performant manner that, in many cases, replaces the need for a server. But the process of developing such a system is overly complicated and involves a lot of hacking and getting around browser's limitations.
Over the last year, our team has been working on creating a **Video Editing SDK** meant to take care of all the issues and limitations mentioned above, while giving you full access to build the flow and interface you want. Check it out at [rendley.com](https://rendley.com/) | rendley |

Real time testing is a crucial part of the Software Development Life Cycle that involves testing software applications for their reliability and functionality in real time. This involves simulating the real-time environment or scenarios to verify the performance of the software application under various load conditions. Due to this, real time testing has become one of the major aspects of software testing. It has been popularized based on its ability to test the software application in its operational mode.
In this fast-growing software industry, organizations struggle to maintain the pace of software application development and its release. In this process, testing application quality, performance, and functionality is the priority phase which helps ensure end-user requirements are fulfilled. However, software testing is a vast domain, and software applications have to undergo various stages of testing that vary from functional to non-functional testing as per software application requirements.
In this Software Development Life Cycle, testing in real-time is like a boon that aims to deliver high-quality applications in a shorter time. This test requires it to be carried out throughout the software development process. It allows testers to identify and resolve the bugs early, which saves time and resources in the long run. Thus, it is easy to be compliant with industry standards and regulations.
## What is Real Time Testing?
Real time testing involves validating the functionality and performance of software applications in the live environment. The primary purpose of real time testing is to lower the probability of the failure of software applications in a real time environment.
You can understand real time testing as a dynamic process that includes monitoring the software application in real time while being executed. Real time testing can be performed using automated, manual, and exploratory techniques. Such tests require specific tools and software testing methodologies that help QAs to simulate real-time scenarios like network latency, high traffic volumes, and system crashes.
This involves testing the capability of the software application to handle unexpected events and situations in real time environments. The testing in real-time principle is based on verifying the software application’s ability to respond correctly and promptly to external stimuli from various sources, such as the network, the user interface, or other connected systems. Thus, it works to ensure that software application functions optimally and consistently, even though it experiences high-volume data or network congestion.
## Why is Real Time Testing important?
Real time testing is the main part of the Software Testing Life Cycle because it gives information on the functionality of the software application in real-world conditions. It helps ensure that the developed software application meets end-user requirements and guarantees performance.
With testing in real-time, you can identify errors or bugs that may occur during the operational or working mode of the software applications. This allows you to fix the software application's bugs before they impact the functionality of a software system.
Testing in real-time gives a broader perspective of the overall software applications. It helps you better understand how software applications function under different situations, allowing you to optimize them for better performance. Therefore, you need to perform real time testing as it helps lower the risk of software application failure and downtime.
## Real Time Testing Example
Suppose you are developing a mobile application that gives real-time weather updates to users. The application extracts data from different APIs, giving end-users weather information and alerts. To test this application in a real-time environment, you perform real time testing that involves various testing types. For example, you perform a functional test to ensure the application works correctly and gives accurate weather data to users. This consists of testing different scenarios, like when the user travels or has a weak Internet connection.
You can conduct performance testing to check the application's response time, resource utilization, and throughput. You can simulate diverse network connections like bandwidth to check how the application responds. It could involve testing the application with real users to check how they interact with the interface and how quickly they find the required information.
In this example, real time testing includes simulating real-world scenarios software applications may encounter, like poor network conditions, user interaction, etc. Hence, its primary purpose is to ensure that the application works optimally and consistently in such an environment and meets the user’s usability, timeliness, and accuracy requirements.
## Where to Perform Real Time Testing?
Performing testing in real-time can be accomplished either on a local machine or in the cloud, each with its unique advantages and disadvantages.
Testing on a local machine allows for greater control over the testing environment. Teams can customize infrastructure and tools to meet their needs, resulting in faster testing cycles without network latency. However, more resources are needed to help scale up to larger scenarios.
Conversely, cloud-based testing offers virtually unlimited resources and scalability without hardware limitations. This method is also cost-effective since teams only pay for the resources they use.
Choosing between these two options depends on project-specific needs such as cost, control, and scalability. Cloud technology has revolutionized real time testing by providing increased flexibility compared to traditional methods. Cloud platforms offer customizable infrastructure and tools that can quickly scale up or down required for varying application loads.
With virtually unlimited resources available on demand through a pay-per-use model, cloud-based testing is particularly beneficial for resource-intensive testing requirements in real-time.
Performing real time testing in the cloud is effective for web and mobile application testing as it excludes the need for local test infrastructure. With cloud-based digital experience testing platforms like LambdaTest, you can simultaneously leverage real time testing on multiple browsers and devices. It offers both manual and automated testing approaches where you can perform real time testing on 3000+ browsers and devices and OS test your software applications.
Here are some key features of LambdaTest:
It allows you to perform real-time cross-browser compatibility testing of software applications. With this, you can monitor the look of the software application on various browsers and devices in real time.
It provides a wide range of Android and iOS mobile devices that enable you to test your software application on old and latest versions of browsers.
While performing real time testing, testers interact with the developed software application as an end-user would. It allows checking for errors, bugs, and other issues which might affect user experience.
Benefits of Real Time Testing
In the development of software applications, it is critical to ensure the application’s functionality is in working mode. In other words, by running tests in a real user environment, developers and testers can quickly find the issue and address them before the application is released in the market.
Testing in real-time lowers the amount of time it takes for features or functions to be tested and deployed. It allows the organization to release its software applications faster and stay competitive.
Here are some other points that describe the benefits of testing in real time:
End-users expect software applications to respond quickly and give accurate results. With testing in real-time, you can ensure that software applications are responsive, fast, and meet end-user expectations.
Testing in real-time lowers the software application downtime by identifying and resolving bugs before they lead to failures.
It allows for optimizing software application performance by finding new areas or features to be improved. By analyzing the software application performance under real-world conditions, you can quickly identify bottlenecks and areas for optimization, which results in faster and more efficient software applications.
Visual components like text, layouts, and other components are easily accessed and tested. It is easy to detect User Interfaces (UIs)/User Experience (UX) issues.
You can perform exploratory testing or ad hoc testing of software applications in a real time approach. This test allows you to explore the software application and try different scenarios and inputs to see how it behaves.
Testing in real-time provides a deeper level of analysis and verification of software applications. You can identify whether reported bugs are real issues and require them to be addressed.
## Types of Real Time Testing
Testing in real-time involves many different types of testing, which are performed to check the quality and functionality of the software applications in real-user scenarios. Here are some of its types:
Functional Testing
In functional testing, the software application's features, workflow, and user interface are tested to ensure its functions as expected. It helps ensure the software application functions per the Software Requirement Specification (SRS). When you run a functional test, you compare each software application function to the corresponding SRS to ascertain whether its result meets the end user's expectations.
Performance Testing
Performance testing is performed to check and verify the performance of the software application under different conditions like high load and stress. The main purpose is to identify performance-related issues like slow response time and determine the software applications' stability, scalability, and speed. With performance testing, you can improve the overall function and performance of the application.
Load Testing
Load testing is categorized under non-functional testing, where a QA tests the performance of the software application under a specific expected load. You can perform load testing in real time to determine how the software application function behaves while being accessed by different users simultaneously. It validates the ability of the software applications to handle a high volume of users, data, and transactions.
Stress Testing
In stress testing, software applications are tested to handle extreme conditions such as high user traffic, unexpected events, etc. In other words, by performing stress testing in real conditions, you can test the robustness of the application beyond the limits of normal operations. Hence, it prioritizes analyzing the software application to maintain robustness, error handling, and availability under heavy load rather than focusing on the behavior under normal circumstances.
Security Testing
Security testing evaluates the software application's security measures against potential threats and attacks. Such a test uncovers vulnerabilities, threats, and risks in software applications. It protects the software application from malicious attacks from intruders.
Usability Testing
Usability testing validates the software application’s ease of use and user experience. It measures how easy and user-friendly software application is by focusing on the flexibility of the application, its ability to meet its objective, and ability to navigate.
Usability Testing
Techniques of testing in real-time are different approaches through which an application is tested against the functional and non-functional requirements of end-users. Such a test involves everything from front to back-end testing, which requires unit and system testing that encompasses real time testing. Such testing can be performed using a manual and automated approach explained below.
## Manual Approach for Real Time Testing
Manual testing is the testing approach where the execution and development of test cases are done manually without using automation testing frameworks or tools. When a software application is tested in real time, some issues or bugs may interfere with its functionality. So, manual testing is performed to make the application stable and bug-free. Testers performing manual testing test the software application from the end-user perspective to develop accurate test cases and give relevant feedback to the developers for timely fixes.
Manual testing in real-time is an approach to testing the functionality of software applications. It allows the team to identify software application issues that automation testing might not detect. With this, it helps to provide crucial feedback on the usability and functionality of the software applications being tested in real time. Based on the feedback, developers fix the issues and ensure the software quality.
Manual testing is particularly important in areas like user experience and exploratory testing performed in real time. This test requires human intervention to make testing flexible and customized as per software application requirements. Testers can modify test cases on-the-fly as they observe the application's behavior. They can also test specific scenarios that automated tests may not cover.
## Automated Approach for Real Time Testing
Automated testing in real-time is the crucial approach to ensure consistent and reliable results. It uses test tools or frameworks to execute pre-scripted tests on a software application before releasing it into production. Each tool and framework is scripted with rules of automation related to the software to be tested. Such frameworks and tools are integrated with components like function libraries, test data sources, object details, and other reusable modules.
Choosing the right automation testing tools for real time testing is crucial, which could optimize the testing process and deliver high-functionality applications with low maintenance costs. Automation testing in real-time is important as it reduces human error and improves the efficiency of the testing process. Automated tests can be conducted much faster than manual tests, enabling testers to uncover more errors in less time.
To automate tests effectively, it is essential to consider which tests require automation and which tools are available to support automation efforts. Certain types of tests, like real time testing, are better suited for automation than others; it provides a level of standardization that can be challenging to achieve with manual testing. Various tools like Selenium, Cypress, Playwright, and Appium exist to aid automation efforts in real time testing.
## Strategies for Optimizing Real Time Testing
Teams need to optimize their real time testing to ensure that software applications or systems are free of defects and issues. There are several strategies that developers and teams can use to achieve this goal.
One such strategy is risk-based testing, where test scenarios are prioritized based on the risk associated with their failure. This approach enables teams to focus on critical scenarios and software applications.
Test automation is another effective strategy for optimizing testing efforts. Automation testing tools can reduce manual effort and increase consistency in testing by executing repetitive test cases more efficiently. Automated testing enables teams to run tests more frequently, leading to faster feedback and bug fixing.
Integrating testing into the development process is crucial for identifying issues early on. By including testing activities throughout the Software Development Life Cycle, teams can unearth issues before they become significant errors and reduce overall costs.
Continuous testing involves running tests continuously throughout the development process to identify issues as they occur rather than waiting until the end of the Software Development Life Cycle. This approach ensures that code changes refrain from introducing new defects.
Data analytics can provide insights into testing trends and identify potential areas for improvement. Teams can analyze test results using data analytics tools to optimize their testing efforts over time.
Adopting these strategies in tandem with one another or individually as needed will lead to high-quality software applications without minimal defects or no issues while ensuring efficient usage of resources by the team involved in its development.
## Real Time Testing Metrics
Real-time QA or testing metrics are crucial to ensure the software application's reliability and performance. When you perform testing in real time, the QA metrics provide insights into the behavior and functionality of the software application in real time. Using such information, it is easy for the developers and testers to quickly identify and resolve any performance-related issues.
Some of the real time metrics and their significance in testing software applications are explained below:
Response time
This metric measures the software application's speed in responding to requests or queries. When you monitor the response time in real time, it is easy to identify issues that delay the response time of the software application. Based on this, you can take relevant action to fix the issue in the software applications.
Throughput
It measures the data or transactions a system processes within a specific period. This metric is important for high-performance software applications that efficiently handle large amounts of data. By monitoring throughput in real-time, developers can identify bottlenecks that may hinder performance and ensure optimal processing speed.
Error rate
The error rate measures the number of errors or failed transactions within a software application. Monitoring error rates in real-time help detect errors and performance issues needing immediate attention. It enables developers to prevent further damage to the software application while ensuring a smooth user experience by promptly identifying and resolving errors.
Availability
It measures how often a software application remains available for use without interruption or downtime. This metric is especially significant for software applications requiring continuous availability, such as online banking or eCommerce platforms. By monitoring availability in real-time, developers can promptly address issues causing downtime and ensure uninterrupted access for users round-the-clock.
Utilization
Monitoring resource utilization helps identify performance issues while optimizing resource allocation efficiently. It measures resource usage percentages such as CPU or memory utilization by a software application at any moment. By allocating resources effectively, developers can improve overall software application performance while preventing resource-related problems.
Latency
Latency refers to the time taken for data transmission from one point to another within a given software application. By monitoring latency in real-time, developers can detect and resolve issues that may cause delays in data transmission, ensuring optimal system performance as expected.
Testing teams need to track these metrics to identify areas for improvement, evaluate their testing process's effectiveness and efficiency, and make data-driven decisions to optimize their testing efforts. For example, measuring response time helps identify areas where delays can cause user frustration or lead to application failure. Measuring throughput helps evaluate how efficiently an application processes large volumes of data. Measuring availability helps ensure an application is always available and responsive when needed.
By using these metrics effectively, testing teams can ensure that software applications are reliable, efficient, and meet end-user expectations while avoiding any errors or defects in their system's functionality, ensuring high-quality performance at all times.
## Tools for Real Time Testing
Testing in real-time can be done using automation testing tools, which not only quickens the testing process but also ensures the software application's quality. Several tools are available for testing in real time; however, the choice depends on their features and the specific requirement of the software application.

## Steps to Perform Real Time Testing
Testing in real-time ensures an application or system performs as expected under normal and peak load conditions. However, it is a multifaceted and challenging task that requires thorough planning and implementation. The process of testing in real-time includes evaluating the functionality, performance, reliability, and user experience of the application or system in real-world scenarios.
**Below are the steps to perform testing in real-time:**
Identifying critical scenarios and designing test cases: The first step in conducting real time testing involves identifying critical scenarios that need to be tested and creating test cases to evaluate these scenarios. It entails scrutinizing the requirements of the application or system and recognizing key performance criteria.
Setting up the necessary infrastructure and tools: Once test cases have been designed, it is necessary to set up the required infrastructure and tools to support testing. It may involve configuring test equipment, establishing data collection and analysis protocols, and creating test environments.

1,908,571 | Observer-Pattern | Javascript Design Pattern Simplified | Part 3 | As a developer, understanding various JavaScript design patterns is crucial for writing maintainable,... | 27,934 | 2024-07-02T09:00:00 | https://dev.to/aakash_kumar/observer-pattern-javascript-design-pattern-simplified-part-3-4cn6 | webdev, javascript, programming, tutorial | As a developer, understanding various JavaScript design patterns is crucial for writing maintainable, efficient, and scalable code. Here are some essential JavaScript design patterns that you should know:
##Observer Pattern
The Observer pattern allows objects to notify other objects about changes in their state.
**Example**
`class Subject {
constructor() {
this.observers = [];
}
addObserver(observer) {
this.observers.push(observer);
}
notifyObservers(message) {
this.observers.forEach(observer => observer.update(message));
}
}
class Observer {
update(message) {
console.log(`Observer received: ${message}`);
}
}
const subject = new Subject();
const observer1 = new Observer();
const observer2 = new Observer();
subject.addObserver(observer1);
subject.addObserver(observer2);
subject.notifyObservers('Hello Observers!');`
##Real World Example
###Stock Market
**Real-World Scenario:** A stock market application where investors subscribe to stock updates. When the stock price changes, all subscribed investors are notified.
**Define the Subject Class:**
```
class Stock {
constructor(symbol) {
this.symbol = symbol;
this.price = 0;
this.observers = [];
}
subscribe(observer) {
this.observers.push(observer);
}
unsubscribe(observer) {
this.observers = this.observers.filter(sub => sub !== observer);
}
setPrice(price) {
this.price = price;
this.notifyObservers();
}
notifyObservers() {
this.observers.forEach(observer => observer.update(this.symbol, this.price));
}
}
```
**Define the Observer Class:**
```
class Investor {
constructor(name) {
this.name = name;
}
update(symbol, price) {
console.log(`${this.name} notified: ${symbol} is now $${price}`);
}
}
```
**Use the Observer Pattern:**
```
const googleStock = new Stock('GOOGL');
const investor1 = new Investor('Alice');
const investor2 = new Investor('Bob');
googleStock.subscribe(investor1);
googleStock.subscribe(investor2);
googleStock.setPrice(1200);
// Alice notified: GOOGL is now $1200
// Bob notified: GOOGL is now $1200
```
##Use Cases of the Observer Pattern
**1.Event Handling Systems:** Used in systems that handle various events and notify subscribers about these events (e.g., event listeners in UI frameworks).
**2.Real-time Data Streaming:** Useful in applications that need to react to real-time data updates (e.g., stock price tickers, live sports scores).
**3.MVC Architecture:** Often used in the Model-View-Controller architecture to synchronize the view when the model changes.
**4.Notification Systems:** Implementing systems that notify users of changes or updates (e.g., social media notifications, email alerts).
**5.State Management:** Useful in state management libraries to manage and propagate state changes across components (e.g., Redux, MobX).
### Conclusion
Understanding these design patterns and knowing when to apply them can greatly improve your coding skills and make you a more effective full-stack developer. They help in creating robust and maintainable code.
Mastering these patterns will help you build better software.

The Impact of Face Recognition on Our Lives | Facial recognition technology has proved to be an innovation with the power to reshape our society.... | 0 | 2024-07-02T08:55:19 | https://dev.to/luxandcloud/big-brother-or-big-benefits-the-impact-of-face-recognition-on-our-lives-45cf | ai, security, machinelearning, discuss | Facial recognition technology has proved to be an innovation with the power to reshape our society. Still, it is a controversial tool capable of influencing our lives both positively and negatively.
On the one hand, facial recognition offers heightened security and convenience. For example, in January 2020, the New Delhi police used facial recognition technology to identify and arrest a criminal who had been evading capture for several years. The system scanned through millions of records and identified the suspect at a public event, leading to a successful arrest.
On the other hand, facial recognition poses profound questions about privacy and surveillance. In 2019, a Michigan man named Robert Williams was wrongfully arrested due to a facial recognition system misidentification. The technology matched his driver’s license photo with surveillance footage of a shoplifter. This incident raised serious concerns about the accuracy of facial recognition systems.
In this article, we will discuss the delicate balance between technological advancement and the preservation of individual freedoms. Join us as we analyze the complexities of facial recognition and its far-reaching implications.

1,908,523 | Factory-Pattern | Javascript Design Pattern Simplified | Part 2 | As a developer, understanding various JavaScript design patterns is crucial for writing maintainable,... | 27,934 | 2024-07-02T08:55:00 | https://dev.to/aakash_kumar/factory-pattern-javascript-design-pattern-simplified-part-2-3fhd | webdev, javascript, programming, tutorial | As a developer, understanding various JavaScript design patterns is crucial for writing maintainable, efficient, and scalable code. Here are some essential JavaScript design patterns that you should know:
## Factory Pattern
The Factory pattern provides a way to create objects without specifying the exact class of the object that will be created.
**Example**
`class Car {
constructor(model) {
this.model = model;
}
}
class CarFactory {
static createCar(model) {
return new Car(model);
}
}
const car1 = CarFactory.createCar('Tesla Model S');
const car2 = CarFactory.createCar('BMW i8');`
## Real World Example
###Example: User Account Creation
***Real-World Scenario:*** A system may need to create different types of user accounts (e.g., Admin, Guest, RegisteredUser). The Factory pattern provides a way to create these objects without specifying the exact class.
**Define User Classes:**
```
class Admin {
constructor(name) {
this.name = name;
this.role = 'Admin';
}
}
class Guest {
constructor(name) {
this.name = name;
this.role = 'Guest';
}
}
class RegisteredUser {
constructor(name) {
this.name = name;
this.role = 'RegisteredUser';
}
}
```
**Create the Factory Class:**
```
class UserFactory {
static createUser(type, name) {
switch (type) {
case 'admin':
return new Admin(name);
case 'guest':
return new Guest(name);
case 'registered':
return new RegisteredUser(name);
default:
throw new Error('Unknown user type');
}
}
}
```
**Use the Factory Class:**
```
const admin = UserFactory.createUser('admin', 'Alice');
const guest = UserFactory.createUser('guest', 'Bob');
console.log(admin); // Admin { name: 'Alice', role: 'Admin' }
console.log(guest); // Guest { name: 'Bob', role: 'Guest' }
```
## Use Cases of the Factory Pattern
### 1.Pattern Object Creation with Varying Complexities
***Use Case:*** When the creation process of an object is complex or requires multiple steps, the Factory pattern can encapsulate the creation logic.
**Example:** Creating different types of documents (e.g., PDFs, Word documents, spreadsheets) where each type has a distinct creation process.
### 2.Switching Between Related Objects Dynamically
**Use Case:** When the application needs to switch between related objects at runtime without modifying the existing code, the Factory pattern allows for dynamic object creation.
**Example:** A notification system that sends alerts via different channels (e.g., email, SMS, push notifications) based on user preferences or system state.
### Conclusion
Understanding these design patterns and knowing when to apply them can greatly improve your coding skills and make you a more effective full-stack developer. They help in creating robust and maintainable code.
Mastering these patterns will help you build better software.

For instance, in April/May 2024, there were at least four AI conventions in Seoul with thousands of attendees. So, what about Kubernetes? Can AI help us manage Kubernetes? The answer is yes. In this article, I will introduce K8sGPT.
# What does GPT stand for?
GPT stands for Generative Pre-trained Transformer. It’s a deep learning architecture that relies on a neural network pre-trained on a massive dataset of unlabeled text from various sources such as books, articles, websites, and other digital texts. This enables it to generate coherent and contextually relevant text. The first GPT was introduced in 2018 by OpenAI.
GPT models are based on the transformer architecture, developed by Google, which uses a multi-head attention mechanism. Text is converted into numerical representations called tokens, often how the usage of these models is priced when provided as a service.
Each token is transformed into a vector via a lookup from a word embedding table based on a pre-trained matrix where each row corresponds to a token and contains a vector representing the token in a high-dimensional space, preserving the semantic information about the token.
| Token ID | Embedding Vector |
|----------|-------------------------------------|
| 11 | [0.12456, -0.00324, 0.45238,...] |
| 19 | [-0.28345, 0.13245, 0.02938,...] |
| 30 | [0.11234, -0.05678, 0.19834,...] |
| 82 | [0.09876, 0.23456, -0.11234,...] |
| 67474 | [0.56438, -0.23845, 0.04238,...] |
At each layer, each token is then contextualized within the context window with other tokens through a parallel multi-head attention mechanism
# What is K8sGPT?
K8sGPT is an open-source project written in Go that uses different providers (called backends) to access various AI language models. It scans the Kubernetes cluster to discover issues and provides the results, causes, and solutions in simple sentences. The target audience for this tool is SRE Engineers, whose duty is to maintain and improve service stability.
## Installation and Configuration
Before performing any queries, it’s mandatory to install the tool in an environment with kubectl and set up the backend that will be used for our queries. In this example, I will install K8sGPT on Ubuntu x64:
```
curl -LO https://github.com/k8sgpt-ai/k8sgpt/releases/download/v0.3.24/k8sgpt_amd64.deb
sudo dpkg -i k8sgpt_amd64.deb
```
Once installed, we can configure it with the desired provider that will interact with the AI service’s APIs. In this example, I will use OpenAI.
- Browse to the Open AI platform https://platform.openai.com/api-keys
- Select the **API Keys** option in the side menu, and click **Create new Secret key**.
Next, add the secret key to K8sGPT so that it can authenticate to the AI service:
```
$ k8sgpt auth add
Warning: backend input is empty, will use the default value: openai
Warning: model input is empty, will use the default value: gpt-3.5-turbo
Enter openai Key:
openai added to the AI backend provider list
```
By default, it will use OpenAI, but you can change it by executing the following command:
```
$ k8sgpt auth list
Default:
> openai
Active:
> openai
Unused:
> localai
> azureopenai
> noopai
> cohere
> amazonbedrock
> amazonsagemaker
$ k8sgpt auth default --provider amazonsagemaker
```
# Analyze the cluster
K8sGPT uses analyzers to triage and diagnose issues in the cluster. Each one of them will result in a series of requests (and subsequent usage of tokens) to the AI service’s APIs. To review which analyzers are enabled, execute the following:
```
$ k8sgpt filter list
Active:
> Pod
> ValidatingWebhookConfiguration
> Deployment
> CronJob
> PersistentVolumeClaim
> ReplicaSet
> Ingress
> Node
> MutatingWebhookConfiguration
> Service
Unused:
> HTTPRoute
> StatefulSet
> Gateway
> HorizontalPodAutoScaler
> Log
> PodDisruptionBudget
> NetworkPolicy
> GatewayClass
```
By enabling and disabling these analyzers, you can limit the requests sent to the AI service APIs and focus on specific types of services. In this demo, we will analyze data coming from the logs and disable the Pods analyzer. To do so, I will execute the following:
```
$ k8sgpt filter remove Pod
$ k8sgpt filter add Log
```
Now that K8sGPT is configured, we can start analyzing the cluster. In this example, I will deploy two pods with incorrect configurations and proceed with cluster analysis using K8sGPT. The first will be a nginx image with a non-existent tag, and the second will be a mysql image without the mandatory parameters.
```
$ kubectl run nginx --image=nginx:invalid_tag
$ kubectl run mysql --image=mysql:latest
```
If you check the pods running on the cluster, you will see that something went wrong:
```
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
mysql 0/1 Error 0 6s
nginx 0/1 ErrImagePull 0 17s
```
Let’s move forward and analyze the cluster with K8sGPT by executing the following:
```
$ k8sgpt analyze -e --no-cache --with-doc
100% |█████████████████████████████████████████████████████████████████████████████████████████████████| (5/5, 34 it/min)
AI Provider: openai
Warnings :
- [HTTPRoute] failed to get API group resources: unable to retrieve the complete list of server APIs: gateway.networking.k8s.io/v1: the server could not find the requested resource

Error: The user "system:kube-scheduler" is forbidden to access the configmaps resource in the kube-system namespace.
Solution:
1. Check the RBAC permissions for the user "system:kube-scheduler".
2. Grant the necessary permissions to access the configmaps resource.
3. Verify the changes by attempting to access the configmaps resource again.
```
As you can see, it provides a list of errors. While some of them are a consequence of the real error, the analyzers also provide correct explanations of the pods misconfiguration.
# Conclusions
This tool should not be considered the sole source of truth but rather as a good starting point for troubleshooting. It narrows the path to discovering the problem in the cluster. Organizations that don’t want to share their data with OpenAI can take advantage of the option to use local AI systems.

mongorestore --uri \"mongodb+srv://<your username>:<your password>@<your cluster>.mongodb.net/<database_name>\" --drop dump
```
### Practical Example
Using BSON for restoration ensures that the data is imported efficiently and correctly, maintaining the original structure and indexes of the database.
## Importing a Collection as a JSON File
### Command Syntax
To import a collection from a JSON file, use this command:
```
mongoimport --uri=\"mongodb+srv://<your username>:<your password>@<your cluster>.mongodb.net/<database_name>\" --drop <file_collection_name>.json
```
### Specifying Collection Names
If you need to specify a different collection name than the file name, use this command:
```
mongoimport --uri=\"mongodb+srv://<your username>:<your password>@<your cluster>.mongodb.net/<database_name>\" --drop <file_collection_name>.json --collection <collection_name_different_then_file_name>
```
## MongoDB Terminologies
### Understanding Namespace
In MongoDB, a namespace refers to the concatenation of the database name and the collection name. This unique identifier helps in organizing and accessing the data efficiently.
## MongoDB Commands

1,908,627 | How ZK-Rollups are Streamlining Crypto Banking in 2024 | The scalability limitations of traditional blockchains have long hindered the mass adoption of crypto... | 0 | 2024-07-02T08:30:46 | https://dev.to/donnajohnson88/how-zk-rollups-are-streamlining-crypto-banking-in-2024-3oi2 | cryptocurrency, blockchain, zkrollups, learning | The scalability limitations of traditional blockchains have long hindered the mass adoption of crypto banking. Enter [ZK-Rollups](https://blockchain.oodles.io/blog/zero-knowledge-zk-rollups/?utm_source=devto), one of the revolutionary [Blockchain application development services](https://blockchain.oodles.io/blockchain-app-development-services/?utm_source=devto) that leverages zero-knowledge proofs to improve transaction processing efficiency. In 2024, ZK-Rollups will rapidly transform crypto banking and offer many benefits.
## Fast Transactions
Traditional blockchains handle only a limited number of transactions per second (TPS). ZK-Rollups bundle numerous transactions off-chain and verify them using zero-knowledge proofs on the main blockchain. This dramatically reduces the load on the main network, enabling near-instantaneous transaction processing within the ZK-Rollup itself. Imagine crypto banking transactions settling in seconds, compared to the minutes or even hours it can take on traditional blockchains.
## Lower Fees
High transaction fees have been a significant barrier to entry for many in the crypto space. ZK-Rollups, by processing a large number of transactions off-chain, significantly reduce the gas fees associated with each individual transaction. This opens up crypto banking to a wider audience and fosters greater participation in the ecosystem. Imagine sending and receiving crypto assets without exorbitant fees eating into your profits.
## Enhanced Scalability
As crypto banking adoption grows, the need for scalable solutions becomes paramount. ZK-Rollups provide a future-proof architecture by enabling the processing of a massive volume of transactions without compromising security. This paves the way for crypto banking platforms to handle a larger user base and accommodate increasing transaction volumes. Imagine a crypto banking platform that doesn’t buckle under the pressure of high user activity.
## Improved User Experience
Slow transaction times and high fees can lead to a frustrating user experience. With their near-instantaneous transactions and lower fees, ZK-Rollups significantly improve the user experience for crypto banking customers. Interacting with cryptocurrency assets is more efficient and seamless due to faster transaction processing and lower fees. Envision a cryptocurrency banking interface that has the same responsiveness as a conventional bank account.
## Unlocking DeFi Potential
Decentralized Finance (DeFi) offers a plethora of innovative financial services. However, scalability limitations on traditional blockchains restrict their full potential. ZK-Rollups, by enabling faster and cheaper transactions, unlock the true potential of DeFi within the crypto banking space. Imagine seamlessly integrating DeFi applications into your crypto banking platform, allowing you to participate in lending, borrowing, and other advanced financial services without leaving your familiar environment.
## Greater Regulatory Compliance
Regulators are increasingly focusing on the crypto space. ZK-Rollups can facilitate compliance with Know Your Customer (KYC) and Anti-Money Laundering (AML) regulations. By allowing crypto banking platforms to implement robust verification procedures without compromising user privacy through zero-knowledge proofs, ZK-Rollups pave the way for a more regulated and trustworthy crypto banking landscape. Imagine a crypto banking platform adhering to regulations while protecting your privacy.
## Enhanced Security
Security remains a top concern for crypto banking users. While ZK-Rollups move transaction processing off-chain, security is not compromised. The validity of transactions is ultimately verified on the main blockchain, ensuring the security of user funds. Additionally, zero-knowledge proofs allow for the verification of transactions without revealing sensitive information, further enhancing the overall security posture of crypto banking platforms. Imagine enjoying the benefits of faster transactions without sacrificing the security of your crypto assets.
## Privacy-Preserving Transactions
Transaction privacy is a growing concern in the digital age. ZK-Rollups leverage the power of zero-knowledge proofs to ensure privacy-preserving transactions. Only essential transaction details, not the entire transaction content, are revealed on the main blockchain. This allows users to maintain a degree of privacy while still participating in the crypto-banking ecosystem. Imagine control over your financial data, with only the necessary information being shared with relevant parties.
## Interoperability with Legacy Systems
Integration with existing financial systems is crucial for the mass adoption of crypto banking. ZK-Rollups can facilitate interoperability by connecting crypto-banking platforms with traditional banking infrastructure. This enables seamless movement of funds between crypto and fiat currencies, fostering greater adoption and mainstream usage. Imagine seamlessly transferring funds between your crypto bank and your traditional bank account.
## Innovation in Cross-Border Payments
Traditional cross-border payments can be slow and expensive. With their fast transaction speeds and lower fees, ZK-Rollups can revolutionize cross-border payments within the crypto banking space. Imagine sending and receiving funds internationally in a matter of seconds without incurring hefty transaction charges.
## The Road Ahead: ZK-Rollups and the Future of Crypto Banking
Integrating ZK-Rollups into crypto banking represents a significant step towards a more efficient, scalable, and user-friendly future. However, the road ahead is paved with both opportunities and challenges. Here’s a glimpse into what the future holds:
Imagine a future where users have greater control over their financial data and can participate in a more open and transparent financial system. ZK-Rollups can help create a more decentralized financial environment, even if they are not entirely decentralized themselves because they still rely on a primary blockchain for ultimate security.
## Final Thoughts
ZK-Rollups are transforming cryptocurrency banking and setting the stage for eventual widespread adoption. Imagine sending crypto internationally in seconds, paying minimal fees, and seamlessly integrating DeFi into your everyday banking. ZK-Rollups bridge the gap between DeFi and TradFi, fostering a more efficient, secure, and user-friendly financial landscape for everyone.

This comprehensive guide will delve into the intricacies of NFT drops, offering insights and practical tips to help you navigate this exciting digital frontier.
**What is an NFT Drop?**
An NFT drop refers to the release of a new collection of NFTs by artists, brands, or developers at a specific date and time. These events are highly anticipated and can attract significant attention from collectors and investors, leading to a surge in demand and sometimes causing platforms to experience heavy traffic.
**Preparing for an NFT Drop**
Preparation is key to successfully participating in an NFT drop. Here are a few steps to help you get ready:
**Stay Informed:** Follow artists and NFT platforms on social media, subscribe to newsletters, and join relevant communities on Discord and Reddit. This will keep you updated on upcoming drops and give you a competitive edge.
**Create and Fund Your Wallet:**Ensure you have a digital wallet set up and funded with cryptocurrency, such as Ethereum (ETH), which is commonly used for NFT transactions. Platforms like MetaMask and Coinbase Wallet are popular choices.
**Understand the Platform:**[ Familiarize yourself with the platform hosting the drop](https://www.solulab.com/). Some popular include OpenSea, Rarible, and Foundation. Knowing how the platform operates will save you time and reduce the risk of errors during the drop.
**Navigating the NFT Drop**
When the drop time arrives, follow these steps to enhance your chances of securing a coveted NFT:
**Be Punctual:** NFT drops often sell out quickly, so be ready a few minutes before the scheduled time. Ensure your internet connection is stable and all necessary tabs are open.
**Monitor Gas Fees:** On platforms like Ethereum, transaction fees (gas fees) can spike during high traffic periods. Use tools like Gas Now to monitor and choose an optimal time for your transaction.
Act Fast but Stay Cautious: While speed is crucial, be wary of scams. Double-check URLs and ensure you’re on the official platform to avoid phishing attacks.
**Keep Records:** Maintain records of your transactions and any associated metadata. This information can be valuable for future reference or resale.
**Engage with the Community:** Join NFT communities to stay updated on trends, upcoming drops, and potential collaborations. Engaging with other collectors and enthusiasts can enhance your overall experience.
**The Broader Impact of NFTs**
NFTs are not just limited to art and collectibles. They are making significant inroads into various industries, showcasing their versatility and potential.
**Here are some examples:**
**Real Estate:**Beyond Reality Estate is a prime example of how NFTs are revolutionizing property transactions, offering fractional ownership and tokenized real estate assets.
**Gaming:** Paint simulator[ apps and other gaming platforms are integrating NFTs](https://www.solulab.com/a-detailed-understanding-of-nft-drops-meaning/), allowing players to own and trade in-game assets, enhancing the gaming experience.
**Cryptocurrency:** The intersection of artificial intelligence cryptocurrency coins and NFTs is opening new avenues for innovation, with projects exploring AI-driven NFT creations and automated master data management systems.
**Examples of NFTs in Daily Life**
NFTs are increasingly becoming part of everyday life. For instance, a pill reminder app could leverage NFTs to reward users for adhering to their medication schedules, creating a unique blend of health and digital art.
Similarly, the integration of Natural Language Processing (NLP) technologies can enhance user interaction with NFTs. An example of NLP in daily life is using voice commands to search for specific NFTs or manage collections.
**The Future of NFTs**
The future of NFTs is promising, with continuous advancements in technology and increasing adoption across various sectors. For instance, buying a house with Bitcoin and securing the deed as an NFT could become a standard practice, streamlining property transactions and reducing fraud.
Additionally, the development of artificial intelligence crypto tokens is set to revolutionize the NFT landscape. These tokens can automate and enhance the creation, management, and trading of NFTs, making the process more efficient and accessible.

It is a type of artificial intelligence that can generate human-like text based on a given input. This technology can be used to create descriptions, stories, or even dialogue for NFTs, adding another layer of value and engagement for collectors.
**Conclusion**
NFT drops are an exhilarating part of the digital art and collectibles market. By staying informed, preparing adequately, and understanding the broader impact of NFTs, you can navigate this dynamic landscape effectively. As technology continues to evolve, the possibilities for NFTs are endless, promising a future where digital ownership and creativity intersect in unprecedented ways.

1,908,612 | Automating User Creation and Management with a Bash Script | Introduction Managing users on a Linux system can be a daunting task, especially in environments... | 0 | 2024-07-02T08:19:05 | https://dev.to/gbenga700/automating-user-creation-and-management-with-a-bash-script-5bad | **Introduction**
Managing users on a Linux system can be a daunting task, especially in environments where you need to create multiple users, assign them to specific groups, and ensure they have secure passwords. This blog will walk you through a Bash script that automates the process of user creation, group assignment, password generation, and logging. This script is particularly useful for system administrators looking to streamline user management.
**The Script**
The script, named create_users.sh, reads a text file containing usernames and group names, creates the users, assigns them to the specified groups, sets up their home directories with the appropriate permissions, generates random passwords, and logs all actions.
**Step-by-Step Breakdown**
Here’s a detailed explanation of what the script does:
1.** Script Initialization:** The script starts by checking if an input file is provided as an argument. It sets the INPUT_FILE variable to the provided argument and defines the log file and password file paths.
```
#!/bin/bash
# Check if the input file is provided
if [ $# -ne 1 ]; then
echo "Usage: $0 <input_file>"
exit 1
fi
INPUT_FILE=$1
LOG_FILE="/var/log/user_management.log"
PASSWORD_FILE="/var/secure/user_passwords.txt"
```
2. **File Existence and Directory Setup :** The script checks if the input file exists. It then ensures the secure directory (/var/secure) exists, creates the log and password files, and sets appropriate permissions and ownership to ensure security.
```
# Check if the file exists
if [ ! -f "$INPUT_FILE" ]; then
echo "File not found: $INPUT_FILE"
exit 1
fi
# Ensure the secure directory exists and set permissions
sudo mkdir -p /var/secure
sudo chmod 700 /var/secure
# Initialize log and password files
sudo touch $LOG_FILE $PASSWORD_FILE
sudo chmod 600 $PASSWORD_FILE
sudo chown root:root $PASSWORD_FILE
```
3. **Password Generation Function: **This function generates a random 12-character password using openssl.
```
# Function to generate a random password
generate_password() {
openssl rand -base64 12
}
```
4.** User Creation and Group Assignment:** This is the core of the script:
- It reads each line of the input file, expecting a format of user;groups.
- It checks if the user or group already exists. If not, it generates a password, creates the user,creates the group sets the password, and logs these actions.
- It sets the home directory permissions to 700 to ensure only the user has access.
- It assigns the user to the specified groups, logging each action.
```
# Read the input file line by line
while IFS=';' read -r user groups; do
# Check if the user already exists
if id "$user" &>/dev/null; then
echo "User $user already exists." | sudo tee -a $LOG_FILE
else
# Generate a random password
password=$(generate_password)
# Create the user with a home directory and set the password
sudo useradd -m -s /bin/bash "$user"
echo "$user:$password" | sudo chpasswd
# Log the creation and password
echo "User $user created with home directory." | sudo tee -a $LOG_FILE
echo "$user:$password" | sudo tee -a $PASSWORD_FILE
# Set the permissions and ownership of the home directory
sudo chmod 700 /home/$user
sudo chown $user:$user /home/$user
# Assign groups to the user
IFS=',' read -r -a group_array <<< "$groups"
for group in "${group_array[@]}"; do
# Check if the group exists
if ! getent group "$group" &>/dev/null; then
# Create the group if it does not exist
sudo groupadd "$group"
echo "Group $group created." | sudo tee -a $LOG_FILE
fi
sudo usermod -aG "$group" "$user"
echo "User $user added to group $group." | sudo tee -a $LOG_FILE
done
fi
done < "$INPUT_FILE"
echo "User creation, group assignment, and logging completed." | sudo tee -a $LOG_FILE
```
**5. Running the Script:** To run the script, save it as create_users.sh, make it executable, and execute it with the input file as an argument:
```
chmod +x create_users.sh
sudo ./create_users.sh <input_file>
```
**Conclusion**
This script will not only create users and assign them to groups but also create any missing groups. This ensures that all specified groups are present, and users are correctly added to them.

1,908,611 | Mobile Development | Hey there! Ever thought about creating cool apps for your phone? Here's your chance! Mobile... | 0 | 2024-07-02T08:18:38 | https://dev.to/dee_codes/mobile-development-epa | mobile, reactnative, xamarin, flutter |
Hey there! Ever thought about creating cool apps for your phone? Here's your chance! Mobile development is an exciting space. Today, I want to share some insights about mobile development platforms, common software architecture patterns, and why I'm excited to join the HNG internship. Let's dive in and have some fun!
## Mobile Development Platforms
**React Native**
Have you ever considered building an app that works on iOS and Android without writing separate code for each? That’s where React Native comes in. Based on JavaScript and React, it allows you to develop cross-platform apps, by reusing a single codebase. If you’re familiar with React for web apps, it’s a smooth transition. However, achieving that perfect native feel sometimes requires extra effort and custom modules.
**Flutter**
Let’s talk about Flutter, a framework created by Google. It uses a widget-based architecture, making it easy to design user interfaces. Flutter compiles directly to ARM, so it runs fast. Learning Dart can be challenging, but once mastered, it makes Flutter a powerful tool in your toolkit.
**Xamarin**
Xamarin, developed by Microsoft, allows you to create apps using C#. If you're a fan of.NET, you'll feel right at home with Xamarin. It supports cross-platform development, enabling you to share a significant amount of code across iOS, Android, and Windows. Integrated with Visual Studio, it offers a dependable development environment. However, it may occasionally be slow to support the most recent platform features, and the apps created using Xamarin may be larger compared to native ones.
**Common Software Architecture Patterns**
MVC stands for Model-View-Controller. It's a way to organize apps. Imagine your app as a theater play: the Model is the script, the View is the stage, and the Controller is the director. It helps keep everything organized, but sometimes the controller can get overwhelmed, like a stressed-out director managing too many actors.
MVVM (Model-View-Model) helps manage data and keep the view clean. It's great for maintainability and testability but can be challenging to learn.
Clean architecture focuses on keeping code clean, modular, and manageable. It enforces separation of concerns and scalability for large projects, requiring a strong understanding of design principles.
I'm excited to share that I've started the HNG Internship, which provides great learning opportunities with experienced developers, real-world projects, and skill enhancement. I'm looking forward to focusing on mobile development, collaborating with fellow interns, and learning from industry experts. The structured learning and practical experience will help me improve my skills. Being part of this community is very rewarding. If you're interested in the [HNG Internship](https://hng.tech/internship), check out their official [website ](https://hng.tech/hire)and explore the [premium](https://hng.tech/premium) section for more information.
Thanks for reading! I’d love to hear your thoughts and experiences, so feel free to drop a comment below. Let’s connect and support each other on this amazing journey! | dee_codes |

1,908,608 | Exploring Scrape Any Website (SAW): Unveiling Challenges and Recommendations 🚀 | Introduction 🛠️ In my recent exploration of Scrape Any Website (SAW), a tool designed for web data... | 0 | 2024-07-02T08:14:53 | https://dev.to/gloria_qa/exploring-scrape-any-website-saw-unveiling-challenges-and-recommendations-4hha |
**Introduction** 🛠️
In my recent exploration of [Scrape Any Website](https://scrapeanyweb.site/) (SAW), a tool designed for web data extraction, I encountered several key issues that impact its usability and functionality. This blog outlines these challenges, provides recommendations for improvement, and details the testing approach used to uncover these issues.
**Exploratory Testing Approach** 🛠️
To thoroughly evaluate SAW, I employed an ad-hoc testing approach, dynamically exploring its features without predefined test cases. This method allowed me to uncover real-world issues that scripted tests might miss, focusing on usability, functionality, and performance across different scenarios.
**Testing Scope 🔍**
My testing scope included:
- Navigation and usability across different pages.
- Exploring core functionalities of SAW to identify bugs and inconsistencies across various features.
- Ensuring consistency in the user interface (UI) and user experience (UX) of SAW.
- Checking responsiveness and speed, particularly during data scraping and processing.
- Identifying potential data vulnerabilities.
**Findings and Recommendations** 📝
Discoveries;
**1. Data Validation 📝:** One of the critical issues identified was that the "Save" button allows users to proceed without entering data in the 'Scrap Job Name' field. This oversight undermines data organization and user guidance.
**2. Scrape Statistics 📊:** Clicking on status codes within the "Scrape Statistics" triggers a "save as" panel on the computer. While this feature aims to facilitate data management, it triggers unexpectedly, potentially confusing users.
**3. Invalid URL Handling 🌐:** Users can input an invalid URL without receiving prompts to correct it. This omission complicates the scraping process, leading to potential data inaccuracies and user frustration.
**4. Inability to Analyze Scraped Data 📉:** After completing a scraping job, users are unable to analyze the data as the system only returns the status code, URL, response time, and file size. This issue prevents users from accessing and effectively analyzing their scraped data.
**5. UI and Data Presentation 🖥️:** The columns and descriptions on the "Scraper" page and other pages lack clarity, organization, and visual appeal. Improving these elements would enhance user navigation and comprehension of scraped data.
**6. Browser Option Issues 🕰️:** While using the browser option "Chrome via Chromedriver," the selected URL for scraping continues to load even after the scraping is completed. This behavior wastes user time and system resources.
**7. Incorrect Status and Value Display ⚠️:** The status and value displayed for scraped websites using 'Chrome via Chromedriver' are often incorrect and lack detailed descriptions, making it challenging for users to interpret results accurately.
**8. Performance Issues 🐢:** Scraping a website using the browser option "Chrome via Chromedriver" frequently exceeds a duration of 10 seconds. This prolonged response time hampers efficiency, especially when handling multiple scraping tasks.

It's about understanding the requirements of the software you want to build i.e. how it should work, your target audience, your proposed user-base quantity e.g. (2,000 users in 2 weeks) and its impact on the software ecosystem at large.
In order for you to fulfill the afore-mentioned requirements, you must understand the common architectural patterns of building _Good_ Software and the platforms of delivering this software.
## Common software Architectural pattens
Let's begin with the common software architectural patterns.
### 1. Model-View-Controller (MVC)
Think of MVC as splitting your software into three parts which in this case would be our mobile application:
- **Model**: This is basically the brains and brawns of your software. It handles your business logic and data. Without this guy, your software is basically a user interface with no function, just for sight seeing
- **View**: This is the user interface (what users see), I'm sure you know what will happen if this little but serious guy isn't available.
- **Controller**: This guy is as the waiter in a restaurant that takes orders from you and sends the requests to the chef, and once your order is ready, the waiter brings it to you, it manages input and update the model and view (the go-between)
### 2. Model-View-ViewModel (MVVM)
MVVM is like MVC with an extra twist. It adds a ViewModel, which acts as a middleman between the Model and View (I'm sure you're wondering, what's the difference, isn't it the same as MVC, don't worry, I'll explain)
- **Model**: Like the MVC this guy manages the data and business logic
- **View**: This guys as well manages the user interface
- **ViewModel**: But this guy, it's like a combination of view and model, to streamline the relationship between your data and your user interface
### 3. Model-View-Presenter (MVP)
MVP is another spin on MVCC, with the Presenter taking charge, (you might ask "what is this presenter?", take a chill man... you'll see it soon):
- **Model**: Data and Business Logic.
- **View**: User interface
- **Presenter**: The presenter acts upon the model and the view. It retrieves data from repositories (the model), and formats it for display in the view

After some time debating which technologies we should use, we decided to go with [Elixir](https://elixir-lang.org/) and [Phoenix](https://www.phoenixframework.org/). In short, these tools gave us the productivity, stability, safety, and scalability (the company was planning on opening up the application to the public, with a new API added to the mix, so future performance was a bit of a concern) that seemed appropriate for the company's plans.
A not-so-technical external consultant that was helping out with other parts of the business asked us to explain this choice, since he had never even heard of Elixir, so we wrote down a few of the reasons that led us to the decision, in a way that anyone with just a little bit of technical background could understand.
I haven't been writing much here lately, and I thought it could make a good blog post for anyone else considering these tools. This was not edited or made more readable for the web, it is just a bullet-list dump of the reasons we wanted to convey at that time, so here you go.
---
It is hard to distill in a condensed version several months of conversations and research about a technology, ultimately leading up to the decision of using it for a project. I tried to summarise everything here but it's still a long read.
Elixir has rock solid stability, which it gains from the BEAM VM (the Erlang underlying platform). Erlang was created by Ericsson for its telecommunications platforms, and to this date is still a very popular choices for mission critical software. Elixir inherits not only the BEAM VM's stability, it also has all of Erlang's [OTP](https://www.erlang.org/faq/introduction#idm24) libraries and middleware available to it (in the same manner that languages that run on the Java VM usually have access to Java packages).
The fact that it is a functional language with immutable principles, along with its pattern matching capabilities and error handling mechanics, means that the resulting code is typically much simpler, easier to reason about, and more robust than the typical result from an object-oriented or imperative language. In turn, this means less bugs, easier maintenance, easier onboarding, etc.
Being a functional language also makes it less popular than other languages. But also because of that, it attracts more people who actually know how to write good software, instead of folks who did a 6-week "bootcamp" and were tricked into thinking they now know everything they need to be good software engineers. This also has an effect on the ecosystem around the language: the quality of Elixir packages is significantly higher than what is found in other more popular languages. In other words, even though there's a smaller pool of people to hire from and libraries to use, the average quality is significantly higher. We don't get as many low-quality developers, or libraries that are inneficient and riddled with bugs and security holes. On top of it, the Elixir community is well known for its friendliness and support, something we have experienced first-hand over the past year.
Elixir has amazing asynchronous and parallel processing capabilities (in its default configuration, the BEAM VM automatically uses all available CPU cores, so we get true parallelism, not just concurreny), granted by very lightweight processes (you can easily have millions of them running in a single simple machine) and associated functionalities that are very useful. These processes are completely isolated, share no variables / memory, and communicate with each other only through message passing. This allows for safe and easy concurrency and parallelism because there are no locks and no race conditions.
These processes are also meant to be discardable: "let it crash" is a guiding principle for writing good software, meaning that if something goes wrong, it should not fail silently while everything keeps running seemingly without a problem. The BEAM VM makes this super easy and transparent because it takes care of automatically restarting a process that terminates abnormally, while still generating logs, warnings, or whatever we need to detect the problem. In other words, Elixir is highly fault-tolerant by default.
An example of why these processes are useful: we don't need separate infrastructure (message broker, task queue, task workers) to run asynchronous tasks as we would traditionally do, along with all the monitoring necessary to keep it running. Elixir's processes and supervision trees make it very easy and very efficient to have background tasks, like what we would use cron jobs for, or task queues (for example, for sending emails, or periodically fetching data from third-party services). This is simple to do with Elixir alone and works just fine but if we want to go further, there is a package called [Oban](https://github.com/sorentwo/oban) which can use the same database as our app (no external broker required), and implements a lot of functionality, like scheduled tasks similar to cron jobs, automatically retrying failed tasks with backoff algorithms, a dashboard with metrics and controls for the queues and tasks, and many other niceties.
The BEAM VM is also extremely efficient in computing resource usage, which means we spend less on infrastructure and, perhaps more importantly, reduce our environmental impact.
Though not as extensive as in other more popular languages, Elixir has many libraries available, the number of which grows by an order of magnitude or two when you consider OTP as well. You'd be surprised by how much is covered by the available packages. Due to not being one of the most popular languages, libraries for specific third-party services may not be available but we've found that for these, we usually only want a very limited subset of its functionality, and we can easily implement something ourselves. For example, there is no official library for accessing OpenAI's API but the only thing their official libraries do is make a few HTTP requests. I would even argue that I'd rather not add yet another dependency to my projects if all it gives me is a way to make HTTP requests.
Elixir and Phoenix are known for low latency when handling requests, which is critical for providing good UX.
On top of that, Phoenix has built-in support for web sockets, which it uses in its Liveview library. It's hard to describe how amazing Liveview is to someone who hasn't used it yet. One of the best things about it is how easy it makes it to implement an application that behaves like an SPA without requiring the [insanity of a full blown frontend framework](https://www.borfast.com/blog/2023/08/01/please-dont-use-react/). It is able to load data in the background (including loading data asynchronously after loading the basic structure of the page, a.k.a. hydration for a fast "first contentful paint") and maintaining a bi-directional communication channel with the backend to modify data, get real-time notifications of any changes, and modify the DOM in a super efficient way (it's so efficient that other frameworks are copying the methods used by Phoenix). This would allow us to create a web app that could be used as a PWA, saving us a ton of time and money until the need for a native mobile app would arise.
Phoenix uses a component-based approach for building web UIs, similar to what React and other popular frontend frameworks do, allowing for good code organisation and reuse.
Phoenix promotes a project structure that separates business logic from data access logic, and from web or API logic. As we talked about before, it is trivial to add API logic to a project that was started with only a web layer that renders HTML.
Both Elixir and Phoenix provide good telemetry and observability capabilities. Phoenix has a built-in dashboard that provides invaluable information and metrics about not only the application performance and health, but also the underlying BEAM VM.
Phoenix is well known for contributing significantly to productivity and developer happiness.

Bonus: [This thread on Reddit](https://www.reddit.com/r/elixir/comments/11ljydy/would_you_still_choose_elixirphoenixliveview_if/) is chock-full of goodness about Elixir and Phoenix. | borfast | |
1,908,598 | Reasons To Embrace Continuous Performance Testing | In today's fast-changing digital world, delivering top-notch applications and services is a must for... | 0 | 2024-07-02T08:01:56 | https://www.robinwaite.com/blog/reasons-to-embrace-continuous-performance-testing | continuous, performance, testing | 
In today's fast-changing digital world, delivering top-notch applications and services is a must for maintaining customer satisfaction and maintaining that leading edge. A system-changer like continuous performance testing (CPT) helps companies take the initiative at each point along their software development path to anticipate and overcome performance bottlenecks. In this article, we will explore five good reasons why any company that cares about achieving great application performance should subscribe to CPT.
1. **Early Detection Of Performance Issues**
CPT's most significant benefit is early problem-diagnosis. Implementing performance tests into the continuous integration and delivery (CI/CD) pipeline can locate any possible bottleneck at its inception, and thus be dealt with there and then. Eliminating performance issues preemptively avoids them getting worse later in the production cycle, thereby reducing costs, saving time and removing the need for additional work.
2. **Improved Software Quality**
Increasing the overall standard of software requires CPT. By routinely validating performance characteristics, organisations may ensure that their apps and services meet the necessary performance criteria before end users use them. By using this trick, it reduces the possibility of installing software that doesn't work, which could lead to unhappy users, financial loss, and bad user experiences.
3. **Increased Agility Along With Faster Time-To-Market**
Agility is crucial in the competitive corporate world of today. CPT facilitates rapid iterations and frequent releases, which help firms adopt an agile mindset. By including performance testing into the CI/CD pipeline, teams may be able to identify and address performance issues more quickly. As a result, testing and deployment cycles take less time. Consequently, companies can reduce time to market and obtain a competitive edge by offering superior, high-performing goods and services.
4. **Scalability And Cost-Effectiveness**
In the long run, scalability and cost-effectiveness can be enhanced by implementing CPT. Organisations can save money and effort by preventing performance problems from arising in production environments by recognising and resolving them early in the development cycle. CPT also helps businesses scale their applications more effectively and maximise resource utilisation, which eventually results in lower operating expenses and a higher return on investment.
5. **Improved Collaboration And Transparency**
Within development teams, CPT promotes a transparent and cooperative attitude. All stakeholders have visibility into the performance characteristics of an application during a development process thanks to an integration of a performance testing into the CI/CD pipeline. Open communication, and knowledge sharing, as well as a cross-functional cooperation are all facilitated by this transparency, which eventually results in better decision-making and higher-quality software as a whole.
**Conclusion**
Continuous Performance Testing is now essential in the quickly changing world of software development. Opkey transforms the performance testing market with its automated, user-friendly, and integrated approach. Non-technical people can easily construct automated tests with its no-code interface. Opkey facilitates a range of end-to-end processes, including ERP deployments and Oracle Cloud migrations.
One important feature is the ability to convert functional tests to performance tests with a single click, which eliminates the need for needless test maintenance because performance tests update immediately in tandem with functional tests. Opkey uses a single interface to enable cross-functional cooperation amongst users of different skill levels. It makes it possible to quickly analyse how quickly an application runs on various browsers.
This creative approach increases productivity, speeds up testing, and maintains quality across digital transformation procedures. | rohitbhandari102 |

1,908,593 | Automating User and Group Management with a Bash Script | Overview For system administrators, maintaining user accounts and groups can be a tedious... | 0 | 2024-07-02T07:55:42 | https://dev.to/afeezaa/automating-user-and-group-management-with-a-bash-script-59je | ## Overview
For system administrators, maintaining user accounts and groups can be a tedious chore. Automating this process can save time and the possibility of human error. Our script, create_users.sh, makes this procedure simpler, which reads user and group data from a file and runs the required system commands.
## Script Breakdown
Let's break down the script to understand how it works.
### Script Initialization
```bash
#!/bin/bash
```
The shebang `#!/bin/bash` tells the system to execute the script using the Bash shell.
### Defining Color Codes
```
# Color codes
RED="\e[31m"
BLUE="\e[34m"
YELLOW="\e[33m"
YELLOW_ITALIC="\e[3;33m"
RESET="\e[0m"
```
We define color codes using ANSI escape sequences to make our script's output more readable. These colors will highlight different types of messages, such as errors, successes, and prompts.
### Logging Function
```
# Function to log actions with timestamps and color coding
log() {
local COLOR="$2"
local TEXT="$(date +"%Y-%m-%d %T") - $1"
echo -e "${COLOR}${TEXT}${RESET}" | tee -a $LOG_FILE
}
```
Timestamped messages are formatted and logged by the log function. It appends these log entries to a log file and shows them on the terminal, using the designated color to distinguish between different log entry types.
### Password Generation Function
```
# Function to generate a random password
generate_password() {
tr -dc A-Za-z0-9 </dev/urandom | head -c 12
}
```
This function generates a random 12-character password using the `/dev/urandom` pseudo-random number generator.
### Root User Check
```
# Check if the script is run as root
if [[ $EUID -ne 0 ]]; then
echo -e "${RED}This script must be run as root or with sudo${RESET}"
exit 1
fi
```
This block checks if the script is being run as the root user or with the sudo command.
### Setting Up Log and Password Files
```
# Default log and password files
LOG_FILE="/var/log/user_management.log"
PASSWORD_FILE="/var/secure/user_passwords.txt"
# Ensure the log and password files exist with secure permissions
mkdir -p /var/secure
touch $LOG_FILE
touch $PASSWORD_FILE
chmod 600 $PASSWORD_FILE
```
We define the paths for our log file and password file. The `mkdir -p /var/secure` command creates the secure directory if it doesn't exist.
### Input File Check
```
# Check if an input file is provided, otherwise prompt the user
if [[ "$#" -ne 1 ]]; then
echo -e "${YELLOW}Enter the filename containing the user information: ${RESET}"
read INPUT_FILE
else
INPUT_FILE=$1
fi
# Validate the input file
if [[ ! -f $INPUT_FILE ]]; then
log "Input file does not exist: $INPUT_FILE" "${RED}" # Red color for errors
exit 1
fi
```
This part checks if the script was given an input file as an argument. If not, it prompts the user to enter the filename. The script then checks if the file exists. If not, it logs an error and exits.
### Processing Each Line of the Input File
```
while IFS=';' read -r username groups; do
# Remove leading and trailing whitespace
username=$(echo $username | xargs)
groups=$(echo $groups | xargs)
# Check if the username is empty
if [[ -z "$username" ]]; then
log "Empty username. Skipping..." "${YELLOW_ITALIC}" # Yellow color for skipped (italic)
continue
fi
# Check if the user already exists
if id "$username" &>/dev/null; then
log "User $username already exists. Skipping..." "${YELLOW_ITALIC}" # Yellow color for skipped (italic)
continue
fi
# Create the user with a home directory
useradd -m -s /bin/bash "$username"
if [[ $? -ne 0 ]]; then
log "Failed to create user $username. Skipping..." "${RED}" # Red color for errors
continue
fi
log "Created user $username with home directory /home/$username" "${BLUE}" # Blue color for success
# Set home directory permissions
chown "$username:$username" "/home/$username"
chmod 700 "/home/$username"
log "Set permissions for /home/$username" "${BLUE}" # Blue color for success
# Create and add the user to additional groups
IFS=',' read -ra group_array <<< "$groups"
for group in "${group_array[@]}"; do
group=$(echo $group | xargs) # Remove whitespace
if [[ ! $(getent group $group) ]]; then
groupadd $group
if [[ $? -eq 0 ]]; then
log "Created group $group" "${BLUE}" # Blue color for success
else
log "Failed to create group $group. Skipping group assignment for $username." "${RED}" # Red color for errors
continue
fi
fi
usermod -aG "$group" "$username"
log "Added user $username to group $group" "${BLUE}" # Blue color for success
done
# Generate and set a random password for the user
password=$(generate_password)
echo "$username,$password" >> $PASSWORD_FILE
echo "$username:$password" | chpasswd
log "Set password for user $username" "${BLUE}" # Blue color for success
done < "$INPUT_FILE"
```
This is the core part of the script. It processes each line of the input file, which is expected to have the format `username;group1,group2,....`
- **Whitespace Removal:** We remove leading and trailing whitespaces from usernames and groups.
- **Empty Username Check:** If a username is empty, it logs a message and skips to the next line.
- **User Existence Check:** If the user already exists, it logs a message and skips to the next user.
- **User Creation:** If the user doesn't exist, it creates the user with a home directory and logs the action.
- **Set Permissions:** It sets appropriate permissions for the user's home directory.
- **Group Management:** The script ensures each group exists and adds the user to the specified groups.
- **Password Management:** It generates a random password, sets it for the user, and securely logs it.
### Final Log and Script Exit
```
log "User creation process completed." "${BLUE}" # Blue color for success
exit 0
```
The script logs that the user creation process is complete and exits with a status code of 0, indicating success.
### How to Run the Script
To execute the script, follow these steps:
1. **Ensure the script has executable permissions**:
```
bash
chmod +x create_users.sh
```
2. **Prepare the input file as shown below;**
```
Lagos;sudo,dev,www-data
Abuja;sudo
Lokoja;dev,www-data
```
3. **Run the script with the input file as an argument:**
```
sudo bash create_users.sh file.txt
```
Find the complete code [Here.](https://github.com/Afeez-AA/HNG1.git)
### CONCLUSION
Administrative operations can be greatly streamlined by using Bash scripts to automate user and group management. This script shows how to create users, manage groups, handle passwords safely, and read user information from a file.
You are welcome to alter this script to meet your own requirements; just keep in mind that scripts should always be tested in a secure setting before being used in production.
