Setting up WordPress with Docker
Published: 2023-08-23 16:23:52

Docker simplifies the process of setting up and managing software across different environments. By using Docker containers, you can ensure that your WordPress site will run the same, regardless of where Docker is running.

**Prerequisites:**

- Docker installed on your machine.
- Docker Compose installed on your machine.

**Steps:**

1. Create a Docker Compose File:

Start by creating a new directory for your WordPress project and navigate into it:

```
mkdir my_wordpress_site && cd my_wordpress_site
```
Now, create a docker-compose.yml file in this directory with the following content:

```
version: '3'

services:
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: somewordpress
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress
    
  wordpress:
    depends_on:
      - db
    image: wordpress:latest
    ports:
      - "8000:80"
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - ./wp-content:/var/www/html/wp-content

volumes:
  db_data: {}

```

**2. Start Your Containers:**

In the terminal, navigate to the directory where your docker-compose.yml is located and run:

```
docker-compose up -d

```
This will start your WordPress and MySQL containers. The -d flag will run them in the background.

**3.Access WordPress:**

Once the containers are up and running, open your browser and go to **http://localhost:8000**. You should see the WordPress installation page. Proceed with the installation by following the on-screen instructions.

**4.Stopping the Containers:**

When you're done, you can stop the containers by running:

```
docker-compose down

```

**Conclusion:**
By using Docker with WordPress, you can quickly set up a development environment without the need for manual configuration or the risk of conflicts with other software. This setup ensures consistency across different machines and can be a foundation for more advanced Docker deployments in the future.

Espero que este guia básico seja útil para você! Há muito mais que você pode fazer com Docker e WordPress, como configurar certificados SSL, otimizar o desempenho e integrar com outras ferramentas.

NumPy Tutorial #3: Array Indexing
Tags: datascience, python, beginners, tutorial
Published: 2023-08-23 16:15:02

{% embed https://youtu.be/ajOUcRhq_vk %}

In the previous blog, I have showed you how to create a NumPy array. In this blog, I will show you how to access data inside the array using index.

First of all, you can create a NumPy array for the example
```python
import numpy as np

list_of_number = [1, 2, 3, 4, 5]

arr = np.array(list_of_number)
```

To get the data inside the array, you can use index to indicate the position of the data. For example, if you run this code
```python
print(arr[2])
```
it will output
```
3
```
And if you run
```python
print(arr[4])
```
you will get
```
5
```

Congratulations! you now know how to access data inside NumPy array using indexing. Thank you for reading this blog, see you next time!
NumPy Tutorial #2: Creating Arrays
Tags: datascience, python, beginners, tutorial
Published: 2023-08-23 16:05:39

{% embed https://youtu.be/YsKLRIhWHj0 %}

To create a numpy array, first you have to import the numpy library into your code
```python
import numpy as np
```
Then, use numpy `array` method to create the numpy array and pass a python list as its argument
```python
list_of_number = [1, 2, 3, 4, 5]

arr = np.array(list_of_number)
```
Not only you can pass a python list as the argument of `array` method, you can also pass a python tuple
```python
tuple_of_number = (1, 2, 3, 4, 5)

arr = np.array(tuple_of_number)
```
When you print the array,
```python
print(arr)
```
you will see the following output
```
[1 2 3 4 5]
```

---

There you go, you have created a NumPy array. Thank you for reading this blog, and see you next time!
Callback functions in Python
Tags: python, coding, programming
Published: 2023-08-23 15:59:44

## Hi 🙂🖐
{% embed https://youtu.be/dBXF3KlCta0 %}

Frist we need to kenow what is **callback function**

A **callback function** is a function that is passed to another function as an argument

## examples

```python

def myFunc():
    print('from myFunc function')
    

def call_func(callback_function):
    callback_function()
    

call_func(myFunc)

```

As you can see, call_func takes another function as an argument.

## another example

```python

def welcome1(name):
    print(f'welcome {name}')


def welcome2(name):
    print(f'Welcome : {name}')


def check_user(name, callback):
    if name == 'amr':
        callback(name)
        

check_user('amr', welcome1)
check_user('amr', welcome2)

```

In this example you can modify the function you are passing to another function, which is one of the advantages. of callback functions

Song Recommender
Published: 2023-08-23 15:58:33



This is a project in the Codecademy CS102 course. It is a simple program to recommend music playlists based on user input.  The program will give a list of music genres that the user can select from. The user types the genre they would like to see, and a list of songs is generated. The songs are from Rolling Stone magazines' Top 500 songs. 

The user should run the Main.py file. The program asks to select a genre. The user types the genre from the list provided and then the program asks if you want to see a list of songs. If the user enters 'y' then a list of songs is generated. The program works by creating a tree from the songs.csv file. The genre is the parent node and the children are the songs in that genre. A breadth-first search algorithm is used to search the tree and provide a list of songs. 

Here is a link to the program:
https://github.com/mjp286/Recommendation-Software-Python.git

The songs.csv file could be altered to make the list of songs more personalized.

Building Faster Websites in 2023
Published: 2023-08-23 15:42:57

Speed is becoming more critical for the web. With new frameworks, APIs, and best practices we can build ridiculously fast user experiences - if we know how.

In this post, I'll share my top tips for optimizing site speed in 2023 and beyond.

Core Web Vitals Pave the Way

Google has been pushing site speed as a ranking factor for years. But Core Web Vitals crystallized exactly what "fast" means for real users.

Focusing on:

- Largest Contentful Paint (LCP)

- First Input Delay (FID)

- Cumulative Layout Shift (CLS)

Optimizing against these metrics directly improves user experience. And it could mean better search rankings.

I recommend treating Core Web Vitals as the North Star for any speed efforts.

Critical Render Path Optimization

The key to fast rendering is optimizing the critical render path - the resources needed to render basic site structure and content.

- Minify HTML/CSS/JS - Reduce file size through minification and compression.

- Code Splitting - Only load JS needed for the initial route. Lazy load other chunks.

- Prioritize Resources - Frontload critical CSS/fonts using preload tags.

- Reduce Requests - Concatenate and bundle CSS and JS files.

- Async JS Loading - Dynamically inject non-critical JS to avoid blocking.

- Caching - Set proper cache headers so resources load instantly on repeat visits.

- Choose Lightweight Frameworks

Many popular web frameworks are packed with features that can bloat page weight.

For faster sites, consider lightweight options like:

- Alpine.js

- Svelte

- Lit

- Hyperapp

Or optimize existing apps with methods like code splitting.

Optimize Images and Media

Images and media are often the biggest page weight culprits.

- Responsive Images - Use srcset to serve properly sized images for device resolution.

- Image Formats - Prefer next-gen formats like WebP and AVIF over JPEG/PNG.

- Lazy Loading - Only load offscreen images when scrolled into view.

- Compression - Reduce image file sizes with lossless tools like TinyPNG.

- SVG Over Raster - Use resolution-independent SVG for simple graphics.

Check Real World Performance

Test speed regularly in the wild:

- Lighthouse - Great metrics on lab performance for Core Web Vitals.

- WebPageTest - Reveals optimization opportunities on real devices.

- SpeedCurve - Tracks performance changes over time.

- [Snowcat Browser](https://snowcat.codeberg.page/) - My open-source browser optimized specifically for speed.

Fast performance directly impacts bounce rates, conversions, and revenue. Users have high expectations - we need to deliver.

Javascript 30 array Methods
Tags: javascript, beginners, array, 30arraymethods
Published: 2023-08-23 15:34:02

## first I will discuss about map method.
The map() method in JavaScript is used to iterate through each element of an array and apply a provided function to each element. It then creates a new array containing the results of applying the function to each element. This is a powerful way to transform elements without modifying the original array.

Usage: array.map(callback(element, index, array))
Parameters:
callback: A function that is called for each element in the array.
element: The current element being processed.
index: The index of the current element.
array: The array being iterated.
Returns: A new array with the transformed values.

Redirecting users from one page to another is a common task in web development. Whether you're using `jQuery `or pure `JavaScript`, this comprehensive guide will equip you with the knowledge to seamlessly navigate users to their intended destinations. Let's explore both approaches with practical code examples.

**Using jQuery for Page Redirection:**

jQuery provides a simple method for redirecting users using the window.location property:


![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/k86cd8iffycdxhs0c67q.png)
**Using Pure JavaScript for Page Redirection:**

In pure JavaScript, you can achieve page redirection in a similar way:

![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/douieng9esq0g45qlus2.png)
**Delayed Redirection:**

If you want to add a delay before redirecting, you can use the `setTimeout `function:


![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/xh4qdey0vzj86gd8jujh.png)

**Passing Query Parameters:**

You can also pass query parameters during redirection:

![javascript](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wk83q0bhc0l9ceacfbn4.png)

**Best Practices:**

`Graceful Degradation:` While `JavaScript `redirection is useful, ensure your website works even if `JavaScript `is disabled in the browser.

Use Semantic URLs: Use meaningful URLs for better user experience and SEO.

**Conclusion:**

Whether you're using `jQuery `or pure `JavaScript`, page redirection is a fundamental skill for guiding users through your web application. By following the examples and best practices in this guide, you'll be able to implement smooth and effective page redirection in your projects.

How to get traffic on website
Published: 2023-08-23 15:01:15

**How to get traffic on website** 


1. Optimize your content with keywords
When you optimize your content with keywords relevant to your business, the process is known as search engine optimization (SEO). Many business relationships are formed after someone types a word or phrase into a search engine to find a website. Knowing the search terms people use to discover your website makes it easier to draw in more visitors. Certain terms may be specific to you, such as a brand or product name. Or, they can be attributes or benefits like “all-natural,” “free delivery,” or something else that sets you apart.

In Google Analytics, you can view what terms your website visitors have used to find you in the past and use those keywords to help you optimize your website content. It's also a good idea to look at the terms your competition uses on their websites, in social media, or in emails.

Google Search Console is another free tool you can use to see how often your website appears in search results, which search terms drive the most visitors, and how many people click on your site in search results.

Tips to maximize your SEO efforts
The tips below can help you maximize your SEO efforts:

Make your website findable. Ensure your site has thorough descriptions of your offerings and their benefits so that search engines like Google and Bing can surface them. Also, create a descriptive SEO title for your website to allow more people to find you. An SEO title can be added as you build your website.
Leverage your website content. Blog posts, articles, audience testimonials, and other content helps improve your search rankings and brings visitors to your website.
Optimize your visuals. While search engines are much better at indexing words than visual elements, images and videos can help boost your Google ranking if they’re optimized for mobile devices. If you’re incorporating images to your website, make sure every image includes short alt text describing the picture or graphic to give the search engine a text alternative to interpret.....Read more[](https://shorturl.at/BFV13)
