Tags: tutorial, flutter, android, computerscience
Published: 2023-07-19 06:02:23

## **Introduction:**  

As a beginner Flutter developer, setting up emulators is a crucial step in the development process. Emulators allow you to test your apps on virtual devices, ensuring they work flawlessly before deploying them to physical devices. In this blog, we will walk you through the step-by-step process of setting up two types of emulators: a physical device and the Android Studio emulator. By the end of this guide, you'll be equipped with the tools to efficiently test your Flutter apps in a virtual environment.

## **Part 1: Setting Up a Physical Device**

**Step 1: Enable Developer Options on Your Device**

- Go to your device's Settings.
- Scroll down and tap on "About phone" or "About tablet."
- Look for the "Build number" entry and tap it multiple times until you see a message saying "You are now a developer."

**Step 2: Enable USB Debugging**  

- In your device's Settings, go to "System" -> "Advanced" -> "Developer options."
- Turn on the "Developer options" toggle if it's not already enabled.
- Enable the "USB debugging" option.

**Step 3: Connect Your Device to Your Computer**  

- Use a USB cable to connect your device to your computer.
- On your device, you may see a prompt to "Allow USB debugging." Tap "Allow" to grant access.

**Step 4: Verify Device Connection**  

**Open a terminal or command prompt on your computer.
Run the command:
` flutter devices`
Your connected device should be listed under "Connected devices."**

## **Part 2: Setting Up the Virtual Emulator**

**Step 1: Create a New Virtual Device**  

- In the AVD Manager in Android Studio, click on "Create Virtual Device."
- Select the device type you want to emulate (e.g., Pixel 3) and click "Next."
- Choose a system image for the device and click "Next."
- Customize the virtual device configuration if desired (e.g., RAM size, VM heap size), and click "Finish."

**Step 2: Start the Emulator**  

- In the AVD Manager, click the green "Play" button next to your virtual device to start the emulator.

## **Conclusion:**  

With both a physical device and the Android Studio emulator set up, you now have the power to test your Flutter apps comprehensively. Emulators provide a risk-free environment to identify and fix issues before deploying your apps to real devices. So, go ahead, create amazing Flutter apps, and embark on a successful development journey! Happy coding!

5 HTML Tags & Attributes ที่ควรรู้สำหรับ SEO
Tags: seo, website, html, webdev
Published: 2023-07-19 05:22:40

[SEO คืออะไร?](https://contentmastery.io/learn-seo/what-is-seo/) เชื่อว่า Dev หลายคนอาจจะเคยได้ยินเกี่ยวกับ SEO มาบ้างไม่มากก็น้อยครับ ซึ่งมันก็คือกระบวนการปรับเว็บไซต์ของเราให้ดีต่อ Search Engine อย่าง Google เพื่อที่ว่า Google จะได้นำเว็บเราไปแสดงผลบนหน้าแรก ๆ นั่นเอง

ส่วนของการทำ SEO ก็มีอยู่มากมายหลากหลายวิธี แต่ในวันนี้เราจะมาทำความรู้จักกับ HTML Tags & Attributes 5 ตัวที่จำเป็นสำหรับ SEO

## Title Tag
Meta Title Tag เป็นส่วนหนึ่งของ HTML tag ที่ใช้ในการกำหนดชื่อหรือหัวข้อของหน้าเว็บไซต์ ซึ่งจะปรากฏบนแถบหัวของเบราว์เซอร์เมื่อผู้ใช้งานเข้ามายังหน้าเว็บไซต์ของคุณ นอกจากนี้ Meta Title Tag ยังมีความสำคัญสูงในการทำ SEO เพราะเป็นหนึ่งในปัจจัยที่ส่งผลต่อการติดอันดับบนเครื่องมือค้นหา

ตัวอย่าง Title Tag
`<title> HTML Tags & Attributes ที่ควรรู้สำหรับ SEO | Dev.to`

## Meta Description
Meta Description คือ แท็กหนึ่งในเว็บไซต์ที่ใช้ในการกำหนดและบรรยายเนื้อหาหลักของหน้าเว็บเพจ ซึ่งจะปรากฏในผลการค้นหาของเครื่องมือค้นหา (เช่น Google) เมื่อเว็บไซต์ของคุณปรากฏในผลการค้นหา โดยปกติแล้ว Meta description จะปรากฏใต้ชื่อเว็บไซต์ในผลการค้นหา และเป็นที่บ่งบอกให้ผู้ใช้รู้ว่าเนื้อหาของเว็บเพจนั้นเกี่ยวข้องกับเรื่องอะไร และสรุปเนื้อหาหลักในหน้าเว็บนั้นๆ ให้กับผู้ใช้งาน

## H1 (Heading Tag)
Heading tag (แท็กหัวข้อ) คือแท็กในภาษา HTML ที่ใช้ในการกำหนดระดับของหัวข้อในเว็บเพจ ซึ่งมีหน้าที่ช่วยให้เนื้อหาบนหน้าเว็บเรียงลำดับและมีโครงสร้างที่เป็นระเบียบ หัวข้อจะช่วยให้ผู้ใช้และเครื่องมือค้นหา (search engine) เข้าใจเนื้อหาของเว็บไซต์ได้ง่ายขึ้น และสามารถนำเสนอหัวข้อและสาระความสำคัญของเนื้อหาให้กับผู้ใช้ได้ถูกต้อง


## alt (Image Alternate Tag)
alt เป็นแท็กที่ใช้สำหรับใส่คำอธิบายรูปภาพเพิ่มเติม ซึ่งควรใส่ให้สอดคล้องกับภาพ เพื่อที่จะให้ Google เข้าใจเกี่ยวกับภาพนั้นมากยิ่งขึ้น ซึ่งจะทำให้ Google นำภาพนั้นมาแสดงเมื่อมีคนเสิร์ชเกี่ยวกับภาพนั้น


## Do follow & No follow
ในเว็บโลกนิยม (World Wide Web), การใช้งานและการตั้งค่าลิงก์ (links) สามารถแบ่งออกเป็นสองประเภทหลัก คือ No-follow และ Do-follow ซึ่งมีความแตกต่างกันดังนี้
- No-follow เป็นแอตทริบิวต์ (attribute) ที่สามารถใส่ในแท็ก `<a>` เพื่อบ่งบอกต่อเครื่องมือการค้นหา (search engine) ว่าไม่ควรติดตามลิงก์นี้ไปยังหน้าเว็บปลายทาง ซึ่งหมายความว่าลิงก์นั้นไม่มีผลต่อการส่งความสำคัญ (link juice) หรือส่งสัญญาณการค้นหาของเว็บไซต์ปลายทางที่เชื่อมโยงไป
- Do-follow เป็นลิงก์ที่ไม่มีแอตทริบิวต์ No-follow ต่ออยู่ในแท็ก `<a>` เพื่อเชื่อมโยงไปยังหน้าเว็บปลายทาง และเครื่องมือการค้นหาจะติดตามลิงก์นี้และให้ความสำคัญในเรื่องของ link juice

ก็จบลงไปแล้วครับสำหรับ 5 HTML Tags ในเบื้องต้นที่ส่งผลต่อ SEO ถ้าเพื่อน ๆ อยากเข้าใจแบบลึกซึ้งเกี่ยวกับ SEO ผมก็มีคอร์สเรียนแนะนำ กับคอร์ส [Free SEO Course](https://contentmastery.io/seo-free-course/) ของเพจ Content Mastery ซึ่งลงทุนลงแรงทำให้เราเรียนแบบฟรี ๆ กันเลยครับ
CSS and HTML
Published: 2023-07-18 19:59:29

HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are two fundamental languages in web development. While closely related, they have different roles and work together to create the structure and visual presentation of a website.

HTML is responsible for defining the structure and content of a web page. It is a markup language that uses tags to indicate the function and semantics of elements on a page. HTML defines basic elements such as headings, paragraphs, lists, links, images, and other components. These tags are organized in a hierarchy of nested elements, allowing for the establishment of the structure and order of content on the page.

CSS, on the other hand, is used to style and design HTML elements. CSS defines how elements look in terms of colors, fonts, margins, sizes, and positioning. It enables the application of consistent styles across an entire website or multiple pages, making it easier to maintain and update the visual appearance. CSS relies on selectors to identify the HTML elements to which styles will be applied and uses properties to establish the visual characteristics of those elements.

The interaction between HTML and CSS occurs through the linking of external CSS files to an HTML document using the <link> tag. This way, the web browser loads the CSS file and applies the defined styles to the corresponding HTML elements.

For example, in an HTML file, you could have the following code:

html
Copy code
<!DOCTYPE html>
<html>
<head>
  <title>Example of HTML and CSS Interaction</title>
  <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
  <h1>Welcome to my website</h1>
  <p>This is an example of how HTML and CSS work together.</p>
  <img src="image.jpg" alt="Example image">
</body>
</html>
In this case, a CSS file named "styles.css" is linked to the HTML document. In that CSS file, you could define styles for headings (<h1>), paragraphs (<p>), and images (<img>), such as background color, font size, and margins.

The separation between HTML and CSS allows for greater flexibility and maintainability in web development. HTML focuses on structure and content, while CSS takes care of visual presentation. By working together, HTML and CSS enable the creation of visually appealing and well-organized [web site design](https://www.vegvisir.marketing/).

The Post Modern Art of Communication
Tags: programming, discuss
Published: 2023-07-19 04:39:22

OhMyPunk! Let's dive right into the juicy topic of coding as a social activity. I mean, come on, we've got social media platforms for programmers like GitHub, where we can mingle, communicate, and collaborate with our fellow code warriors. It's like a virtual coding party where we can all show off our skills and share our knowledge. Isn't that cool?

Now, here's the thing: _I believe that knowledge should be free, floating around like a unicorn in the wild_. But you know what's even more valuable? **Ethics**, my firends. Yep, that's right. Being an ethical coder is worth its weight in gold. We're not just here to write lines of code; we're here to make a positive impact and build something amazing.

> Coding is a social skill, it's a communication act. It produces art that people will look at and be either fascinated or terrified from. - @mattiaorfano

{% embed https://dev.to/mattiaorfano/coding-is-social-activity-29ee %}

I mean, dang! That hits home, doesn't it? As a fellow storyteller and writer, I completely get it. Programming is a way for us to communicate with computers and humans alike. It's not just about writing, visual art, or audio—_it's a whole new dimension of expression_.

But here's the burning question: How do we provide hands-on experiences for users and the businesses that host them? Well, my firends, the answer lies in crafting killer content that not only educates but also captivates. We need to create content that wraps its virtual arms around the reader and says, "Hey, let's go on this coding adventure together!"

So, let's whip up some content that packs a punch and gets our readers engaged. We're aiming to provide understanding, attract readers, and spark some serious discussions. We want people to read our words and say, "Wow, this coding stuff is amazing! I want to join the conversation!"

So buckle up, friends! We're about to starting on a coding journey like no other. Let's write content that's as compelling as a summer blockbuster, as surprising as a magic trick, and as thought-provoking as a midnight existential conversation. Let's make coding the coolest social activity on the planet!

Now, I want to hear your thoughts! Let's jump into the comment section and discuss all things coding. Are you ready? Let's go!
A funny or embarrassing moment
Published: 2023-06-27 13:23:22

hello!!!!
my name is Mugisha Ghad

My most embarrassing moment is when am in front of the teacher, was when I was in the third grade and I peed my pants for the very first time.

Teacher called me up to the front to read a book so I went up to read a book and the moment,  
I was standing in front of the whole class I realized, I really needed to pee really bad there I was holding my crotch really tight and my legs were shaking really bad.
 
The teacher asked me why was I holding my crotch and why was my legs shaking I told the teacher, I needed to pee really bad but she just said I would have to hold it, so I continue to read the book thinking if I paid no attention the feeling of needing to pee would pass but it didn't it only got worse and then before I knew it there I was standing in front of the whole class peeing my pants I was peeing so hard and by the time I got done peeing I had soaked my entire front of my jeans and my pee was running all over the floor and you could literally see the outline of my penis and testicles through my tight jeans because I was wearing no underwear the teacher got so mad she made me clean up my pee using paper towels and then she told me I was going to have to stay in my pee soaked jeans for the rest of the day I was so embarrassed because I thought all the other boys were going to make in front of me but they didn't most of them told me they enjoyed watching and pee my pants so from then on if the teacher would not let me go to the restroom I would just sit there and pee my pants and let it run all over the floor I even had a few other boys that would join me and pee in their pants.

That was my embarrassed moment in my life, thank you!!!
Enlaces desde widgets
Published: 2023-07-19 03:53:45

¿Cómo abrir recursos desde Cards en widgets?
Primero debe agregarse  una acción "wire:click" mediante el método extraAttributes en la definición de la card.
El método debe estar definido en la clase como público y puede recibir parámetros.
Ejemplo (simplificado)
  

```php
class StatsOverview extends BaseWidget
{
    protected static ?int $sort = 0;
    protected static ?string $pollingInterval = null;
    
    protected function getCards(): array
    {
        return [
            Card::make('Instituciones', Institution::count())->description('Instituciones')->color('success') ->extraAttributes([
                'class' => 'cursor-pointer',
                'wire:click' => 'golink("institutions")',
            ])
            ->descriptionIcon('heroicon-s-library'),
            Card::make('Bibliotecas', Library::count())->color('danger')->description('Bibliotecas ingresadas')->
            extraAttributes([
                'class' => 'cursor-pointer',
                'wire:click' => 'golink("libraries")',
            ])];
           
    }
  
        public function golink($resource){ 
        return   redirect()->route('filament.resources.'.$resource.'.index');
        }

}
```

En el ejemplo ambos cards tienen enlace a sus páginas iniciales de "resources".

PHP echo var_dump print_r print
Published: 2023-07-19 03:46:37

In PHP, `var_dump()`, `echo`, and `print` are useful functions for displaying data, but they have different purposes and behaviors. Here's a breakdown of each function:

- `echo`:
   The `echo` statement is used to output one or more strings or variables to the browser or command line. It does not return a value and can handle multiple arguments separated by commas. It is typically used for simple output and HTML generation. For example:

   ```php
   $name = "John";
   echo "Hello, " . $name; // Output: Hello, John
   ```

- `print`:
   `print` is similar to `echo` and can also be used to output strings, but it only supports a single argument. Like `echo`, `print` does not return a value. It is less commonly used than `echo`, but the behavior is almost identical. For example:

   ```php
   $name = "John";
   print "Hello, " . $name; // Output: Hello, John
   ```

- `var_dump()`:
   `var_dump()` is a debugging function used to display structured information about one or more variables, including their type, value, and size. It is commonly used during the development and debugging phase to inspect the contents of variables. `var_dump()` outputs more detailed information than `echo` or `print` and returns `NULL`. For example:

   ```php
   $name = "John";
   $age = 30;
   var_dump($name, $age);
   /* Output:
     string(4) "John"
     int(30)
   */
   ```

   `var_dump()` is especially useful when working with complex data structures like arrays and objects, as it displays information about their internal structure.

- `print_r()`:
   `print_r()` is a function similar to `var_dump()` but provides a more human-readable output. It is mainly used for displaying the contents of arrays and objects during development. Unlike `var_dump()`, `print_r()` does not show the variable type or size and returns `true`. For example:

   ```php
   $fruits = ['apple', 'banana', 'orange'];
   print_r($fruits);
   /* Output:
      Array
      (
          [0] => apple
          [1] => banana
          [2] => orange
      )
   */
   ```

   `print_r()` offers a more concise representation of arrays and objects, making it easier to read and understand.

While `echo` and `print` are commonly used for simple output and HTML generation, `var_dump()` and `print_r()` are primarily used for debugging and inspecting the contents of variables. It's essential to choose the suitable function based on your specific use case.
