Published: 2023-08-16 06:18:47

Setting up a LAMP (Linux, Apache, MySQL, PHP) stack and installing WordPress on it involves several steps. Here's a general guide to help you get started:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/z3vysbj85wokkh98ho8l.png)


1. **Prepare Your Linux Server:**
   - Choose a Linux distribution (e.g., Ubuntu, CentOS) for your server. Update the system packages using the appropriate package manager (e.g., `apt` for Ubuntu, `yum` for CentOS).
   - Install necessary utilities like `wget` and `curl`.

2. **Install Apache:**
   - Install the Apache web server using your package manager.
   - Start and enable Apache to run at system startup.
   - You can test if Apache is working by entering your server's IP address in a web browser.

3. **Install MySQL:**
   - Install MySQL server and client using your package manager.
   - During the installation, you'll be prompted to set a root password for MySQL.
   - Secure your MySQL installation using the provided script (`mysql_secure_installation`).

4. **Install PHP:**
   - Install PHP and necessary PHP modules using your package manager.
   - Once installed, restart the Apache service to apply the changes.

5. **Create MySQL Database and User:**
   - Log in to MySQL as the root user: `mysql -u root -p`
   - Create a new database: `CREATE DATABASE dbname;`
   - Create a new MySQL user and grant privileges to the database: 
     ```sql
     CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
     GRANT ALL PRIVILEGES ON dbname.* TO 'username'@'localhost';
     FLUSH PRIVILEGES;
     ```
   - Exit MySQL: `EXIT;`

6. **Download and Configure WordPress:**
   - Download the latest WordPress installation package: `wget https://wordpress.org/latest.tar.gz`
   - Extract the package: `tar -xvzf latest.tar.gz`
   - Move the WordPress files to the Apache web root directory: `sudo mv wordpress/* /var/www/html/`
   - Set appropriate permissions: `sudo chown -R www-data:www-data /var/www/html/`
   - Rename the sample configuration file: `mv /var/www/html/wp-config-sample.php /var/www/html/wp-config.php`
   - Edit `wp-config.php` and provide the MySQL database, username, and password you created earlier.

7. **Complete WordPress Installation:**
   - Open your web browser and navigate to your server's IP address or domain name.
   - Follow the WordPress installation wizard:
     - Choose your language.
     - Enter the site title, username, password, and email.
     - Click "Install WordPress."

8. **Secure Your Server:**
   - Regularly update your server's packages and applications.
   - Consider implementing a firewall (e.g., `ufw`) to restrict access.
   - Keep backups of your data and configurations.

Remember that this is a simplified guide, and the specifics might vary based on your Linux distribution, server setup, and any changes in software versions. Always refer to official documentation for your chosen Linux distribution, Apache, MySQL, PHP, and WordPress for the most accurate and up-to-date instructions.
Optimizing Website Load Times: Best Practices
Published: 2023-08-16 06:16:28

# Optimizing Website Load Times: Best Practices

Website load times play a crucial role in user experience and search engine rankings. A fast-loading website not only retains users but also performs better in search engine results. Let's explore some best practices to optimize website load times.

## 1. Optimize Images

Large image files can significantly slow down your website. Use tools like TinyPNG or ImageOptim to compress images without compromising quality.

```html
<img src="optimized-image.jpg" alt="Optimized Image">
```

## 2. Minify CSS and JavaScript

Minifying removes unnecessary characters from your code, reducing its size and improving load times.

```javascript
// Before minification
function add(a, b) {
  return a + b;
}

// After minification
function add(a,b){return a+b;}
```

## 3. Use a Content Delivery Network (CDN)

CDNs distribute your content across multiple servers worldwide, ensuring users download resources from the closest server.

## 4. Browser Caching

By setting expiry dates on certain types of files, you can store them in the user's browser cache. This reduces the need for repeated downloads.

## 5. Optimize Web Fonts

Limit the number of different fonts and font weights. Use modern formats like WOFF2 for better compression.

## 6. Reduce Server Response Time

Consider using a high-quality hosting provider and optimizing your backend code. Tools like Google's PageSpeed Insights can provide insights into server performance.

## 7. Implement Lazy Loading

Lazy loading defers the loading of off-screen images and content, ensuring that only what's visible to the user is loaded initially.

```javascript
<img data-src="image.jpg" class="lazyload">
```

In conclusion, optimizing website load times is essential for both user experience and SEO. By implementing these best practices, you can ensure a faster and more efficient website.
Ruby Design Patterns | BUILDER ⚒️
Tags: ruby, rails, programming, architecture
Published: 2023-08-16 06:10:08

## Overview
Builder is a creational design pattern that allows create complex objects step by step.

## Introduction
When you hear the word builder, you probably think of a construction worker however, in this case, we should think of a builder as an object that is able to build new objects based on multiple elements. Imagine a restaurant that sells Tortillas. The owner had the idea that each customer would be able to compose their own tortillas and gave the customers several options to choose from:

- **Meat:** chicken or mutton
- **Vegetables:** cucumbers, tomatoes, and onions
- **Sauce:** mild or spicy
- **Spicy sauce has 3 levels:** medium, hot, and extra hot


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nfw2j5cfxtvpwxv2otaq.png)

## Code Example
So let's create a **Tortilla** class that will have attributes such as **meat**, **sauce**, and **vegetables** that will be an array.

```ruby
class Tortilla
  attr_accessor :meat, :vegetables, :sauce
  
  def initialize
    @vegetables = []
  end
end
```

In addition, we will create a few empty classes that will be represented by individual ingredients.

```ruby
class Chicken; end
class Mutton; end
class Cucumber; end
class Onion; end
class Tomato; end
class MildSauce; end
```

We will also add an attribute to a **spicy sauce** that will determine its level of spiciness.

```ruby
class SpicySauce
  attr_reader :level

  def initialize(level)
    @level = level
  end
end
```

Now we need to prepare a **builder** class that will help us create our tortilla.

```ruby
class TortillaBuilder
  attr_reader :tortilla

  def initialize(tortilla)
    @tortilla = tortilla
  end
 
  def select_chicken
    tortilla.meat = Chicken.new
  end
  
  def select_mutton
    tortilla.meat = Mutton.new
  end
  
  def add_cucumber
    tortilla.vegetables << Cucumber.new
  end
  
  def add_tomato
    tortilla.vegetables << Tomato.new
  end
  
  def add_onion
    tortilla.vegetables << Onion.new
  end
  
  def select_garlic_sauce
    tortilla.sauce = GarlicSauce.new
  end
  
  def select_spicy_sauce(level = :hot)
    tortilla.sauce = SpicySauce.new(level)
  end
end
```

Now, using the **builder** class, we want to create a **tortilla** that will contain:

- _Chicken meat_
- _Two cucumbers_
- _One Tomato_
- _Extra spicy sauce_


```ruby
builder = TortillaBuilder.new(Tortilla.new)

builder.select_chicken
builder.add_cucumber
builder.add_cucumber
builder.add_tomato
builder.select_spicy_sauce(level: :extra_hot)
```

At this point, we have created an interface that allows us to quickly and easily create a new object with freely chosen properties.

Guess what happened yesterday?

Kubernetes 1.28 dropped and so did the [ARMO's matching blog post](https://www.armosec.io/blog/kubernetes-1-28-security/). In the post we rounded up security features related to this version and gave a tl;dr for them.

So, as you dive into version 1.28, just make sure you keep #security in mind too.
Classification of Cyber Attacks
Tags: attacks, vulnerabilities, cybersecurity, security
Published: 2023-08-16 05:39:47

There are many different types of cyber attacks, each with their own purpose, techniques, and mitigation strategies. Some of the most common types of cyber attacks are:

DoS and DDoS Attacks: These attacks aim to overwhelm the resources of a system to make it unavailable to legitimate users. DDoS attacks use multiple compromised devices to launch a larger attack.

MITM Attacks: In these attacks, the attacker inserts themselves between two communicating parties. They can then intercept and modify communications.

Phishing Attacks: Attackers send fraudulent emails or messages to trick users into sharing sensitive information or installing malware.

Ransomware: The attacker encrypts the victim's data and demands a ransom payment in exchange for decrypting the data.

Password Attacks: Attackers try to guess or steal user passwords through brute force, dictionary, or social engineering techniques.

SQL Injection Attacks: Attackers inject malicious SQL commands into a web application's input fields to gain access to the database.

Malware Attacks: Attackers use malicious software like viruses, worms, trojans, and spyware to damage, disrupt, or gain access to a system.

Insider Threats: People within an organization who have access and knowledge can pose a security risk if they act maliciously.

XSS Attacks: Attackers inject malicious scripts into a web application to be executed by a victim's browser.

Eavesdropping Attacks: Attackers intercept network traffic to steal sensitive information like passwords and credit cards.

Those are some of the major categories of common cyber attacks. To defend against them requires a layered approach using tools like firewalls, antivirus software, intrusion detection, multi-factor authentication, employee training, and more. A comprehensive cybersecurity strategy is essential to mitigate today's evolving threats.

So, this is my first pot and i hope it won't get so controversial. 

A year a go, i took this commitment and started to learn how to code and as everyone else, i chose the front end path. Say to say, I'm still not employed yet and still on the limb to learn. It's a long journey, especially when I'm not a CS grad and have a degree which is not related to CS AT ALL.

On my day to day journey, i used to watch youtube videos, not only tutorials, but also career advice on how to learn and what to do. One of the most repeated subjects on youtube was the tutorial hell videos. 

Everyone will tell you to stop doing tutorial hell and start doing a few things on your own. But is this the right thing to do? Well, it is and it's not. Just wanna let you know that i confess that youtube nowadays is one best resources to learn anything and the tutors and creators are doing nothing but the best job to produce the best content in different fields. 

Let's get back a few years ago when we used to attend school or even college, the teacher, doctor, or professor (I'll refer as GURU just for easiness) would start a subject, explain, and even show you some practice. After all of this, the GURU would give you a task and solve it on your own, also home tasks to do in order to discuss them the next day. Isn't this a tutorial? Well, kinda. 

Yet, doing this all over again, won't let you become at the same level as the GURU, that's where you should start learning on your own. 

So as a beginner, isn't it okay to fall in  tutorial hell seems to be a good thing to get grasp and understanding.

Yet, you should also use the tutorial hell wisely, do not just copy paste the same thing the tutor writes without understanding on why they chose such approach or what different approaches or technologies we can use to solve such problem, This is where you start making a good use of the tutorials and gain experience until you get to the point where you will not need tutorials anymore. 

I hope this wasn't too long to read and me also as a beginner seeking to learn from more experienced fellows so all opinions are welcome.  

PS: i don' know if I'm correct about this but i watched lots of videos of self-taught programmers who already made it on their own have already been in the tutorial hell. Correct me if I'm wrong here.
Domina los Subprocesos en Java: Una Continuación de la Serie de Concurrencia
Tags: hilosenjava, concurrenciaenjava, java
Published: 2023-08-16 05:00:00

**Introducción**

Bienvenidos nuevamente a nuestra serie de concurrencia en Java. En el artículo anterior, exploramos los fundamentos de la concurrencia y cómo se heredan los hilos en Java. Hoy, continuaremos nuestro viaje, adentrándonos en el emocionante mundo de la creación y gestión de subprocesos. ¡Prepárate para descubrir cómo hacer malabares con múltiples tareas en paralelo!

**Creación y Gestión de Subprocesos en Java**
La concurrencia en Java se basa en la ejecución de subprocesos. Un subproceso es una unidad de ejecución que comparte recursos de la aplicación. En lugar de crear subclases de **_Thread_**, es una buena práctica implementar la interfaz **_Runnable_**. Veamos un ejemplo:


![Ejemplo 1](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/47hyli44yg2rxk7v7cwg.png)

**Estados de los Hilos y su Herencia**
Los hilos en Java pueden tener varios estados, como mencionamos en el primer artículo. Vamos a profundizar en algunos ejemplos de estos estados:

1. **Nuevo:** Cuando se crea una instancia de **_Thread_** pero no se inicia con el método **_start()_**.
2. **Ejecutable**: Después de llamar a **_start(_)**, el subproceso está listo para ser ejecutado por el planificador.
3. **En Ejecución**: El subproceso está siendo ejecutado actualmente.
4. **Bloqueado**: Si el subproceso está esperando para adquirir un monitor (**_synchronized_**).
5. **Terminado**: Cuando la ejecución del subproceso ha finalizado.

**Ejemplo de Estados de Hilos**

![Ejemplo 2](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6qv0nten7dlyg3m210hj.png)

**Beneficios de Usar la Interfaz Runnable**

- **Mayor flexibilidad**: Al implementar _**Runnable**_, aún puedes extender otra clase si es necesario.
- **Separación de responsabilidades**: Promueve un mejor diseño al separar la lógica de ejecución del subproceso de la implementación de **_Thread_**.

**Conclusiones y Continuación**
En este artículo, hemos continuado nuestra exploración de la concurrencia en Java, enfocándonos en la creación y gestión de subprocesos. Hemos visto cómo implementar la interfaz **_Runnable_** para definir las tareas de los subprocesos y cómo gestionar sus estados. En los próximos artículos, nos adentraremos en más aspectos emocionantes de la concurrencia, ¡así que mantente al tanto!

Designing and Developing an EA NHL 23 App for my Club Team
Tags: react, api, es6, uxdesign
Published: 2023-08-16 04:57:09

I am trying to build up a portfolio of personal projects, so I am attempting to take a stab at creating a React App that is using the EA NHL API to keep track of information on my club team.
  
EA has an API that people can use to look up recent game results, member stats, and club information. This immediately made me want to design a site for my friends' club team. I went straight into Figma and had a blast designing a navigation, a scoreboard like you see on major league sites (MLB, ESPN, NHL, etc), and a rosters page. The more I use Figma, the more I learn how much I enjoy UX/UI design.


![Wireframes of EA NHL team website created in FIGMA](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/27rct7xvnkcl66l5rnfb.png)
  
After finishing a couple of wireframes, I decided to get to the dirty work of building my React app. I am using Vite to host the server locally. I had to go back and re-watch some tutorials to get my new app up and running, but ultimately it was pretty easy. I was good to start coding my homepage within 15-20 minutes of googling and watching videos. This is always my least favorite part of starting a new project.
  
Wanting to dive right into working with the EA API, I began styling the scoreboard. I used hard-coded data to get the HTML structure and CSS just right before spinning wheels on populating the component with live data. 
  
Once I started testing my API calls, I immediately ran into an issue with CORS authorization. After some Google-Fu, I downloaded a Chrome extension that helps suppress these errors while working in a local dev environment. But, my errors didn't end there. It turns out, that even though you can enter the API calls into your browser and get the JSON printed out, EA does not allow unauthorized API hits from personal apps and sites.
  
To get around this, I manually copy & pasted the JSON into a local .json file, and am hosting it in the same folder as my app. The Recent Games API only returns the most recent 5 games, but it was enough to get started. The API actually returns an impressive amount of information. My long term plan is to build a "master" JSON file where I can add a new file every week or so to build up a database of all recent games. Manually uploading is going to be the way to go for now, I don't think EA will ever make the API fully public.


![Screenshot of scoreboard in progress - Score reads: BLUELINE BAKERY: 3, HUS AV ULVUR: 1](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/yfs28bx59u940tfqy9be.png)
  
Anyway, I just got the basic "bones" of my scoreboard component laid out, and fully populated with data from the API/local JSON file. While not overly impressive, I am proud I was able to get here myself.

I am posting this as a way to keep track of my progress on this project and hold myself accountable. I am hoping that by the end of the month I can have the full-site up and hosted on a real domain!
