The .split Method
Published: 2023-11-28 18:40:47

The **.split** method is a built-in method; it takes in a string and **returns an array**.

If we pass it a bit of text in parentheses, .split will divide the string wherever it sees that bit of text. 

For example: 

```ruby 
text. split(",")
```

This code tells Ruby to split up the string text wherever it sees a comma.

For example:

```
text = "cat chased the mouse"
text.split(" ")
```

output: ["cat", "chased", "the", "mouse"]

SaaS significa "Software as a Service" (Software como Serviço, em português). É um modelo de distribuição de software em que o software é hospedado na nuvem e disponibilizado pela internet sob demanda.

Em vez de adquirir e instalar o software localmente em um computador, os usuários acessam o software através de um navegador da web ou de um aplicativo. Eles pagam por assinatura, geralmente mensal ou anual, para utilizar o serviço.

Alguns exemplos claros de SaaS incluem:

Microsoft 365: Anteriormente conhecido como Office 365, oferece acesso online às ferramentas de produtividade da Microsoft, como Word, Excel, PowerPoint, Outlook, entre outros. Os usuários pagam uma assinatura para acessar e utilizar essas ferramentas diretamente pelo navegador.

Salesforce: Uma plataforma de CRM (Customer Relationship Management) baseada na nuvem. Ajuda empresas a gerenciar relacionamentos com clientes, vendas, serviços e marketing. Os clientes acessam e utilizam seus recursos por meio de um navegador.

Netflix: Embora não seja um software empresarial, o modelo de negócios da Netflix é um exemplo de SaaS na indústria do entretenimento. Os assinantes acessam filmes e programas de TV via streaming, pagando uma taxa mensal para utilizar o serviço.

Slack: Uma plataforma de comunicação empresarial que oferece bate-papo, colaboração em equipe e integração de ferramentas. Os usuários acessam o Slack através de um aplicativo ou navegador, pagando por planos de assinatura conforme o uso.

Adobe Creative Cloud: Fornece acesso a uma variedade de aplicativos para criação, como Photoshop, Illustrator e Premiere Pro. Os usuários podem acessar e utilizar esses aplicativos mediante assinatura.

Estes são apenas alguns exemplos de SaaS, mas há muitos outros disponíveis em diferentes setores e para várias finalidades, todos seguindo o modelo de entrega baseado na nuvem e pagamento por assinatura.

Cómo crear un servidor web en tu proyecto vanilla javascript
Tags: webdev, javascript, programming, beginners
Published: 2023-11-28 18:17:14

Para crear un servidor web en tu proyecto vanilla Javascript, te recomiendo seguir los siguientes pasos:

## 1. Inicializa el proyecto.

Abre un terminal en la carpeta donde estás trabajando en tu proyecto y escribe el siguiente comando:

```bash
npm init -y
```

Este comando va a inicializar un nuevo proyecto y crear un archivo `package.json` con valores predeterminados:

```json
{
  "name": "prueba",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}
```
Si deseas personalizar estos valores deberás escribir el comando sin el `-y` al final, es decir quedaría así: `npm init`

**Nota:** para poder ejecutar el comando npm, debes tener instalado node primero en tu computador. Si no lo tienes, o no estas seguro de cómo saber si lo tienes instalado, [acá](https://dev.to/davichobits/como-instalar-node-en-tu-computador-2e2c) te explico instalarlo.

## 2. Istala el paquete `serve` de `npm`

Para hacer esto, en el terminal escribe el siguiente comando:

```bash
npm install --global serve
```
Para ver más detalles sobre el paquete serve en npm haz clic [aquí](https://www.npmjs.com/package/serve?activeTab=readme)

## 3. Configura un script para ejecutar el comando

Ve a tu archivo `package.json` y agrega la siguiente línea `"start": "serve src/ -s"` en el objeto scripts:

```json
{
  "name": "prueba",
  "version": "1.0.0",
  "description": "",
  "main": "src/index.html",  // La página que se va a mostrar
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "serve src/ -s" // La línea que tienes que agregar
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}
```
También podrás ver que modificamos la línea donde se especifica desde dónde se va a lanzar la página.  En el ejemplo el archivo principal está alojado en dentro de la carpeta SRC y tiene el nombre index.html (este archivo debe existir en tu proyecto)

Listo, con esto puedes ir a tu consola y ejecutar el servidor con el siguiente comando

```bash
npm start
``` 

Con esto se inicializará el servidor generalmente en el puerto 3000 si no se encuentra ocupado. Podrás ver el servidor funcionando si te sale algo parecido a la siguiente captura, en tu terminal:

![consola](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4393ewqzko5yinhw3el4.png)

Para acceder a la página, solamente tienes que ir a la dirección que te indica `http://localhost:3000` si quieres verla de forma local o `http://172.18.48.1:3000` si quieres vela dentro de tu red.

Use socket.io in react native with nodejs server
Tags: reactnative, react, node, socket
Published: 2023-11-28 18:01:13

Certainly! React Native can be integrated with Socket.io to enable real-time communication in mobile applications. Here's a basic guide on setting up Socket.io with React Native:

Install Required Packages:
Install the necessary packages using npm or yarn. You'll need socket.io-client for the client-side and socket.io for the server-side.

bash
Copy code
npm install socket.io-client
For the server-side (if you have a backend), you'll also need:

bash
Copy code
npm install socket.io
Set Up Socket.io Client in React Native:
Import and set up the Socket.io client in your React Native component.

javascript
Copy code
import React, { useEffect } from 'react';
import io from 'socket.io-client';

const YourComponent = () => {
  useEffect(() => {
    const socket = io('http://your-server-address'); // Replace with your server address

    socket.on('connect', () => {
      console.log('Connected to server');
    });

    // Handle other events as needed

    return () => {
      socket.disconnect();
    };
  }, []);

  return (
    // Your component JSX
  );
};

export default YourComponent;
Server-Side (Optional):
If you have a server, set up Socket.io on the server. Here's a simple example using Express:

javascript
Copy code
const express = require('express');
const http = require('http');
const socketIo = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = socketIo(server);

io.on('connection', (socket) => {
  console.log('Client connected');

  // Handle events from clients

  socket.on('disconnect', () => {
    console.log('Client disconnected');
  });
});

const PORT = process.env.PORT || 3000;
server.listen(PORT, () => {
  console.log(`Server running on port ${PORT}`);
});
Usage:
You can now emit and listen for events between the React Native client and the server.

javascript
Copy code
// Emit an event from the client
socket.emit('chat message', 'Hello, server!');

// Listen for events on the client
socket.on('chat message', (msg) => {
  console.log(`Received message: ${msg}`);
});
Make sure to replace 'http://your-server-address' with the actual address of your server. This is a basic setup, and you can customize it based on your application's needs.
My Bootcamp Journey So Far...
Published: 2023-11-28 17:28:19

It's been a minute since I've had some time to update my journey, but today I felt the need to. I started my full-stack web dev journey in early September and it has been a journey. A journey of ups and downs. A journey of late nights, long hours of busting my head, long hours of searching the docs, and so on. It has all been worth it. I can't state enough it has been totally worth it.

# What I have learned
I'm excited to mention that I have learned and continue to learn html/css/javascript, and various frameworks to make applications more dynamic. In the past two months, I've learned how to use node.js, express, SQL, NoSQL, MongoDB, Mongo/Mongoose, and MySQL design tools. I've learned how to use API extensions such as Insomnia and ThunderClient. 

I have to admit that I haven't fully mastered or completely learned the above skills. However, I desire to grow in my understanding and ability to incorporate those skills. I am thankful for my instructor who, from time to time makes mistakes or has to go to the docs herself to figure something out. It really encourages me to continue learning and not give up.

# Currently Learning
Currently, I am learning how to use REACT. I must say, it is difficult and at times overwhelming. So far we have used REACT for front-end application projects and it is amazing. Soon, I will be learning how to use REACT for back-end application projects and how to connect front-end and back-end in an application. It's going to be a challenge, however, I look forward to it.   

# Reflection
 As the end of my bootcamp nears I look back and remember that learning never stops. I will always be "currently learning". Imposter Syndrom is a real thing and have faced it from time to time in these past two months. My instructor shared this article with me and I will forward that article to you all as well. I'm sure many of you have read it and that is awesome.  The article was written by Dan Abramov who coauthored REACT and mentions all the things he doesn't know as of 2018. Pretty sure there is an updated version. Reading the article reaffirmed my understanding that we are always learning and that it's okay not to know everything or something within this amazing DEV community.

A importância de utilizar o design atômico
Tags: atomicdesign, development, flutter, mobile
Published: 2023-11-28 17:37:15

Uns dias atrás preparei uns slides para apresentar para alguns colegas desenvolvedores, no intuito de compartilhar o conhecimento que vamos adquirindo com o passar do tempo.
O tema escolhido foi "Atomic Design" porque eu acredito que esse é um tema bem interessante para desenvolvedores que querem sempre melhorar suas habilidades e conhecimentos.
Originalmente o design atômico foi uma metodologia desenvolvida para auxiliar na criação de design systems, para padronizar a criação de layouts e acelerar os processos de criações.
Porém podemos pegar essa metodologia emprestada para o desenvolvimento em geral, pois conseguimos perceber várias vantagens a partir da sua utilização, como consistência, escalabilidade e reaproveitamento.
A proposta na metodologia é composta pela divisão em átomos, moléculas, organismos, templates e páginas. A partir de uma ordem de complexidade crescente e de envolvimento de mais ou menos subcomponentes.
Na apresentação eu trouxe alguns detalhes sobre cada uma dessas divisões e também falo um pouco sobre as vantagens da sua utilização.
Vou deixar aqui o link da apresentação e também o link do youtube que contém o vídeo desse momento.

Linear & Binary Search in DSA
Tags: dsa, javascript, datastructures, tutorial
Published: 2023-11-28 17:35:44


## Linear search:

### Algorithm:
1. **Start at the beginning:** Start your search from the first item in the list.
2. ** Comparison:** Compare each element sequentially with the target.
3. **Matching found:** If a match is found, return the index.
4. **No Match**

### Pseudocode:
```Python
function linearSearch(arr, target):
    for i from 0 to length(arr)-1:
        if arr[i] equals target:
            return i
    return -1
```

### Real life example:
Consider looking for specific items in your shopping bag. You go through each item until you find what you're looking for.

### Asymptotic Notation:
- **Time complexity:** O(n) (linear time complexity)

### Use judgment and opinion:
- Suitable for small databases or unordered lists.
- Simplicity and ease of implementation make it a good choice for basic research requirements.
- Linear search is important when the data is not sorted in any order.

## Binary search:

### Algorithm:
1. **Organize the list:** Make sure the list is organized before starting the search.
2. **Define pointers:** Set pointers low and high to the beginning and end of the list.
3. **Average calculation:** Calculate the average of the current search area.
4. **Comparison:** Return the pointer if the middle element is the same as the target.
5. **Adjust the pointers:** If the target is less than the middle element, repeat the process in the left half; otherwise, repeat on the right half.
6. **Repeat:** Continue until the target is found or the pointer converges.

### Pseudocode:
```Python
binary search function (ar, target):
    organize
    below = 0
    height = length (ar) - 1
    if low == high:
        average = (low + high) / 2
        if ar [middle] is equal to target:
            back to the middle
        else ar [middle] <target:
            low = medium + 1
        other
            high = medium - 1
    return -1
```

### Real life example:

Consider looking up specific words in an organized dictionary. You open the book in the middle, determine whether the word is in the first half or the second, and repeat until you find the word.

### Asymptotic Notation:

- **Time complexity:** O(log n) (logarithmic time complexity)

### Use Cases and Considerations:

- Very efficient for large databases, especially when the data is ordered.
- Binary search does not apply to unstructured data because it depends on the ability to partition the search space.

## The results:

Understanding the nuances of linear and binary search allows you to choose the right algorithm based on the characteristics of your data and the specific requirements of your search operation. Simplicity and versatility (linear search) or efficiency and structured data (binary search) are the most important, this algorithm offers a valuable tool for searching data in various scenarios.
