**O que é a Busca Binária?**
A busca binária é um algoritmo de busca eficiente que encontra a posição de um valor-alvo dentro de uma lista ordenada. Ele compara o valor-alvo com o elemento do meio da lista; se eles não são iguais, a metade na qual o valor-alvo não pode estar é eliminada, e a busca continua na metade restante até que seja bem-sucedida.

Hello World in Node.js
Published: 2024-01-26 15:10:05

# Hello World in Node.js

Node.js is a powerful runtime environment that allows us to build server-side applications using JavaScript. In this guide, we will walk you through the process of creating a simple "Hello World" program in Node.js.

## Prerequisites

Before getting started with Node.js, make sure that you have it installed on your machine. If not, head over to the official Node.js website (https://nodejs.org/) and download the latest stable version suitable for your operating system.

## Creating a New Project

To begin, open up your favorite code editor or integrated development environment (IDE). Create a new empty folder for our project and navigate into it using your command-line interface. To create our "Hello World" application file, follow these steps:

1. Open a terminal or command prompt.
2. Navigate to the directory where you want to create your project.
3. Run the following command: `touch app.js`. This will create an empty JavaScript file named "app.js".

## Writing Our "Hello World" Code

Now that we have our project set up with an empty JavaScript file named "app.js", let's write some code!

Open the **app.js** file in your preferred text editor and enter the following code:

```javascript
console.log("Hello World!");
```

This simple line of code will output the phrase `"Hello World!"` to the console when executed.

Save **app.js** by pressing `Ctrl + S` (or `Cmd + S` on macOS) and close it afterward.

## Executing Our Program

To execute our program and see our "Hello World" message printed out to the console, follow these steps:

1. Open up your terminal or command prompt.
2. Navigate into the directory where you created **app.js**.
3. Type `node app.js` in your terminal/command prompt and press Enter/Return.

You should now see the phrase `"Hello World!"` printed out to your console. Congratulations, you have successfully executed your first Node.js program!

## Conclusion

In this guide, we walked you through the process of creating a simple "Hello World" program in Node.js. We learned how to set up a new project, write our code, and execute it using the Node.js runtime environment.

Now that you have a basic understanding of how to create and run a simple Node.js program, you can explore more advanced topics like working with modules, building web servers, or developing scalable applications.

Happy coding!

Learning Docker - Installing
Tags: tutorial, docker, containers
Published: 2024-01-26 16:17:30

## 02. Installing Docker Community Edition on CentOS

**Overview**

In this lesson, we explore the process of installing Docker Community Edition (CE) on a CentOS server. The article provides a step-by-step guide to setting up Docker CE in a CentOS environment, demonstrating its installation and configuration for practical use.

**Installing Docker CE**

- **Installing Required Packages:** Essential packages for Docker CE in CentOS, such as `utils`, `device-mapper-persistent-data`, and `lvm2`, are installed using the yum package manager.

```
$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
```

- **Adding Docker Repository:** The Docker CE repository is added using the `yum-config-manager` tool to ensure access to Docker packages.

```
$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
```

- **Docker Installation:** Docker CE and its CLI (Command Line Interface) are installed with specific version numbers. Additionally, containerd.io is installed without specifying a version to get the latest one.

```
$ sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
```

- **Starting Docker Service:** The Docker service is started and enabled to run at boot using `systemctl` commands. CentOS requires explicit configuration for services to start.

```
$ sudo systemctl enable --now docker.service
$ sudo systemctl status docker.service
```

**Configuring Docker CE**

- **Verifying Installation:** The installation's success is verified by running sudo `docker version`, confirming that both client and server details are returned.
- **User Permissions:** To allow non-root users (like ec2-user) to execute Docker commands, they are added to the docker group using `usermod`.

```
$ sudo  usermod -aG docker ec2-user
```

- **Re-login for Group Changes:** Users must log out and log back in for group changes to take effect.

```
$ docker version
```

**Testing Docker Installation**

- **Running a Test Container:** To ensure the Docker installation is functional, a simple hello-world container is run. This container prints a message to the console and exits, indicating that Docker can pull images and run containers successfully.

```
$ docker run hello-world
```

The Technological Leap: Understanding Blockchain Integration in Video Games
Tags: blockchain, web3, gamedev, programming
Published: 2024-01-26 14:22:28


In the realm of video gaming, a technological leap is occurring, one that promises to redefine the industry’s future. The integration of blockchain technology into video games is not just a trend; it’s a transformative movement. This article aims to demystify how blockchain is being integrated into video games and the profound implications it has for players, developers, and the gaming industry at large.

**What is Blockchain in Gaming?**
Blockchain technology, at its core, is a decentralized ledger that records transactions across multiple computers in a way that the registered data cannot be altered retroactively. When applied to video games, it introduces concepts like true digital ownership, decentralized assets, and new economic models within the gaming universe.

**True Digital Ownership and NFTs**
One of the most significant innovations blockchain brings to gaming is the concept of true digital ownership through Non-Fungible Tokens (NFTs). These tokens represent ownership of unique items within games, such as skins, characters, or even in-game real estate. Unlike traditional games where in-game purchases are bound to the game and have no value outside, NFTs can be bought, sold, or traded on various platforms, often for real-world value.

**Decentralized Gaming Economies**
Blockchain enables the creation of decentralized gaming economies. In these economies, in-game currencies and assets can have real economic value and be traded in marketplaces outside the game. This economy blurs the lines between virtual and real-world economies, creating new financial opportunities for players and developers.

**Enhanced Security and Transparency**
The integration of blockchain in video games also enhances security and transparency. The immutable nature of blockchain ensures that in-game transactions and histories are secure from tampering. This transparency builds trust among players, especially in games involving trades or purchases.

**The Future of Blockchain in Gaming**
As technology evolves, we are likely to see more sophisticated and seamless integration of blockchain in video games. This could include cross-game compatibility of assets, more sustainable blockchain solutions, and even fully decentralized gaming platforms. The potential for blockchain in gaming extends beyond just economic models to potentially changing how games are developed, published, and played.


**Conclusion**
The integration of blockchain technology into video games marks a significant technological leap in the industry. It’s not merely about adding a layer of cryptocurrency transactions but rethinking the very foundations of how games are played, owned, and valued. As developers and players navigate this new landscape, the possibilities are as vast as they are exciting. Blockchain in gaming is not just a fleeting trend; it’s a glimpse into the future of digital entertainment.
Unveiling Hidden Lombok Magic: 3 Jazzed-Up Annotations for Java Joy
Tags: java, lombok, development
Published: 2024-01-26 14:21:51

Java developers, buckle up! We all know the classic Lombok annotations like `@Getter`, `@Setter`, and `@Builder`, but let's dive into the groove of three underappreciated Lombok annotations that will jazz up your Java journey with fun and flair.

## 1. 🎤 @Delegate: Let Your Code Jam Together

Ever felt like a coding rockstar trying to harmonize different classes or interfaces? Enter the `@Delegate` annotation – it's like having your own backup band! Say goodbye to manually strumming out forwarding methods; `@Delegate` is here to do the heavy lifting for you.

```java
import lombok.experimental.Delegate;

interface Serenade {
    void playMelody();
}

public class Symphony implements Serenade {
    @Delegate
    private Orchestra orchestra = new Orchestra();
}

class Orchestra implements Serenade {
    @Override
    public void playMelody() {
        System.out.println("🎶 Orchestral Melody");
    }
}
```

With `@Delegate`, your code becomes a symphony of collaboration, where the `Symphony` class effortlessly lets the `Orchestra` take the lead. It's like having a concert at your fingertips without the stress of managing every note.

## 2. 🤹‍♂️ @Synchronized: The Juggler of Thread Safety

Thread safety can feel like juggling flaming torches – one misstep, and it all goes up in smoke. Fear not, for the `@Synchronized` annotation is your virtual juggling assistant. Wrap your methods in this annotation, and voila – no more dropping the concurrency balls!

```java
import lombok.Synchronized;

public class JugglingExample {
    private int jugglingBalls = 0;

    @Synchronized
    public void tossBall() {
        jugglingBalls++;
        System.out.println("🤹‍♂️ Juggled a ball!");
    }

    @Synchronized
    public int getJugglingBalls() {
        return jugglingBalls;
    }
}
```

With `@Synchronized`, your code becomes a juggling act where thread safety is as smooth as a well-practiced toss. No more jitters or dropping the ball – it's circus time with confidence!

## 3. 🏰 @Value: Immutable Kingdoms of Code

Imagine your code as a majestic castle – solid, unyielding, and impervious to meddling. The `@Value` annotation is the royal decree that turns your classes into immutable fortresses. Declare your fields, and let Lombok build the castle walls for you.

```java
import lombok.Value;

@Value
public class ImmutableCastle {
    String castleName;
    int towerCount;
    boolean isMajestic;
}
```

With `@Value`, your code transforms into an unassailable fortress, impervious to mutability invaders. No more worries about sneaky changes – your code kingdom is secure and majestic.

In the grand symphony of Java development, these three Lombok annotations—`@Delegate`, `@Synchronized`, and `@Value`—are the jazz, juggle, and castle of fun and productivity. So, put on your coding dancing shoes, throw in some jazz hands, and let Lombok's hidden magic turn your Java journey into a joyful and playful experience! 🚀🎉
Fading an LED with Arduino

2. Connect the long leg (anode) of the LED to a resistor (270Ω) and to pin 13 on the Arduino. (Use a jumper wire for it to reach the Arduino pin)

Before we continue, here is how I arranged the components on the breadboard. (Insert an image of the new circuit)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/a67bvgqy4z5qg6w3to4y.jpg)
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pd3nmv0yb2c3765y9k48.jpg)


### Step 2: Connect your Arduino board to your computer:
Use the appropriate cable for your Arduino board.

### Step 3: Writing the Code:

``` cpp
// Fading a single LED
int ledPin = 13; // Pin number for the LED

void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as an output

}

void loop() {
 for (int brightness = 0; brightness <= 255; brightness++) {
    analogWrite(ledPin, brightness);
    delay(5); // Adjust the delay for the desired fade speed
  }

  // Fade out
  for (int brightness = 255; brightness >= 0; brightness--) {
    analogWrite(ledPin, brightness);
    delay(5); // Adjust the delay for the desired fade speed
  }
}
```

### Step 4: Uploading the Code:
Make sure that in your Arduino IDE, the correct board is selected, and click on the upload button.

Your code should be uploaded successfully.

Test Your Fading LED:
Run the uploaded code on your Arduino board, and you should observe the LED fading in and out, creating a smooth fading effect.

Happy coding! ✨
