using namespace std;

int main() {
    float num1, num2, resultado;
    char operador;

    cout << "Ingrese el primer número: ";
    cin >> num1;

    cout << "Ingrese el operador (+, -, *, /): ";
    cin >> operador;

    cout << "Ingrese el segundo número: ";
    cin >> num2;

    switch (operador) {
        case '+':
            resultado = num1 + num2;
            break;
        case '-':
            resultado = num1 - num2;
            break;
        case '*':
            resultado = num1 * num2;
            break;
        case '/':
            if (num2 != 0)
                resultado = num1 / num2;
            else {
                cout << "Error: División por cero no permitida" << endl;
                return 1; // Salir del programa con código de error
            }
            break;
        default:
            cout << "Operador inválido" << endl;
            return 1; // Salir del programa con código de error

Part 7: Modeling Microservice
Tags: microservices, softwareengineering, learning
Published: 2024-04-25 14:25:31

In this post, we briefly talk about modeling microservices. microservices are just another form of modular decomposition one that has network-based interaction between the models and all the associated challenges that brings. Now let us delve into three concepts we talked about in previous posts.

## Information Hiding
 Information hiding describes a desire to hide as many details as possible behind a module boundary.
With information hiding we achieve:
- Improved development time by allowing modules to be developed independently, we can allow for more work to be done in parallel and reduce the impact of adding more developers to a project.
- Comprehensibility
Each module can be looked at in isolation and understood in isolation. That makes the system easy to understand.
- Flexibility by being able to change modules independently and mix them to create new functionality.
To achieve the above characteristics, it lot depends on how the module boundaries are formed. Information hiding was a key technique to help get the most out of modular architectures, and with a modern eye, the same applies to microservices too.

## Cohesion
The code that changes together, stays together. we’re optimizing our microservice architecture around the ease of making changes in business functionality—so we want the functionality grouped in such a way that we can make changes in as few places as possible. We want related behavior to sit together. If the related functionality is spread across the system, we say that cohesion is weak—whereas for our microservice architectures, we’re aiming for strong cohesion.

## Coupling
The whole point of a microservice is being able to make a change to one service and deploy it without needing to change any other part of the system. This is really quite important. A loosely coupled service knows as little as it needs to about the services with which it collaborates. 

In the next post, we will talk deeply about coupling.
Get the Table Name From a Model in Laravel
Tags: laravel
Published: 2024-04-25 14:19:39

Sometimes we need to reference table names throughout our codebase, like when we're using the DB facade.

Although table names don't change often, I still get an uneasy feeling of hardcoding them. It's so much better to reference the model directly so we have one source of truth for the table name.

So, let's learn how to do that! We'll also create a trait that allows static access to any of our model table names to keep our code a little tidier.

If you don't know, Laravel provide a method to get table name from model instance 
```php
((new User))->getTable()
```
Above code should return the table name, in our case its `users`. 

But we don't have new instances always. Its better if we can get the table name statically. 
We can get the table name by following. 

1. Add method in model 
```php
public static function getTableName() 
{
    return with(new static)->getTable();
}
```

2. Get the table name statically 
```php
User::getTable() // users
```

## Tip
You can put method in trait and drop it any mode.

In today's digital era, amidst a deluge of emails clamoring for our attention, one insidious tactic stands out for its precision and deceptiveness: spear phishing. Unlike traditional phishing endeavors that cast a wide net, spear phishing takes a targeted approach, zeroing in on specific individuals or organizations with meticulously crafted emails aimed at deception.

But what exactly constitutes spear phishing, and how does it operate? Our in-depth examination delves into the intricate workings of a spear phishing attack, from the initial reconnaissance phase to the culmination of its payload. Through real-world instances and expert insights, we unveil the strategies employed by cyber adversaries to exploit human trust and circumvent our defenses.

Drawing clear distinctions between spear phishing, phishing, and the more sophisticated whaling attacks, we provide clarity on the varying degrees of sophistication and the distinct targets of each. From unsuspecting employees to high-profile executives, the threat posed by these malicious cyber tactics knows no bounds.

Nevertheless, amidst the looming threat, hope shines through in the form of proactive measures and informed strategies. From scrutinizing sender details to implementing multi-factor authentication, we outline actionable steps to mitigate the risks associated with spear phishing attacks.

For businesses seeking comprehensive protection, we underscore the significance of cloud defense solutions like CloudDefense.ai. By offering advanced security measures tailored to safeguarding cloud environments and applications, these solutions serve as a formidable barrier against evolving cyber threats.

In summary, while spear phishing may pose a formidable challenge, it is one that can be overcome through vigilance and informed action. By remaining vigilant, staying informed, and adopting proactive measures, we can navigate the digital landscape with confidence, ensuring the safety of our valuable data and assets.
