Hey Dev.to community! 👋

If you've ever found yourself lost in the labyrinth of your database schema, fear not! Today, we're diving into the wonderful world of visualizing database schemas using the powerful tool, PGAdmin4. 🚀

**Why Visualize Your Database Schema?**

Understanding the structure of your database is crucial for effective development and maintenance. Visual representations make it easier to grasp relationships, spot potential issues, and communicate with your team. Let's turn those complex tables and relationships into a visual masterpiece!

**Getting Started with PGAdmin4**

1. **Install PGAdmin4:** If you haven't already, grab PGAdmin4 from the official website or your package manager.

2. **Connect to Your Database:** Open PGAdmin4 and connect to your database. It's like opening the door to a whole new world!

**Visualizing Your Schema:**

1. **Navigate to the 'Browser' Tab:** This is where the magic happens. In the browser tab, you'll see your database listed.

2. **Right-Click and 'Schema' → 'Create' → 'ER Diagram':** The ER Diagram (Entity-Relationship Diagram) is your visual representation.

3. **Drag and Drop Tables:** PGAdmin4 lets you drag and drop tables onto the canvas. Arrange them logically to represent your data flow.

**Customizing Your Diagram:**

1. **Adding Relationships:** Drag from one table to another to create relationships. This is where you'll see the connections between your data.

2. **Color Coding:** Use colors to differentiate between tables, highlighting key entities or indicating relationships.

3. **Adding Comments:** Right-click on any table or relationship to add comments. Documenting your schema directly on the diagram is a great practice.

**Tips for an Effective Visualization:**

1. **Keep It Simple:** Don't overcrowd your diagram. Focus on the most critical tables and relationships.

2. **Use Layers:** PGAdmin4 allows you to create layers, making it easy to toggle between different views of your schema.

Dockerizing Apache on Ubuntu 22.04, A Practical Approach
Published: 2023-10-22 12:51:43

Dockerizing Apache on Ubuntu 22.04 can greatly benefit your development process and provide a practical and efficient way to manage and deploy your Apache web server. Docker allows you to encapsulate your application and its dependencies into a lightweight and isolated container, making it easily portable across different environments.
To begin the process, you'll need to have Docker installed on your Ubuntu 22.04 server. Once you have Docker up and running, you can follow these steps to Dockerize Apache.
1. Create a new directory on your server where you'll be storing your Docker-related files. For example, you can create a folder called "docker-apache" using the command: 
$ mkdir docker-apache
2. Change into the directory: 
$ cd docker-apache
3. Create a new file called "Dockerfile" inside the "docker-apache" directory. 
4. Open the "Dockerfile" with a text editor and add the following content:
```
# Use the official Apache base image
FROM ubuntu:22.04
# Install Apache
RUN apt-get update && apt-get install -y apache2
# Expose port 80
EXPOSE 80
# Start Apache in the foreground
CMD ["apachectl", "-D", "FOREGROUND"]
```
5. Save and close the "Dockerfile".
6. Build the Docker image by running the following command from the "docker-apache" directory: 
$ docker build -t my-apache .
This will build the Docker image using the instructions defined in the "Dockerfile". It may take a while, depending on your internet connection and the server's resources.
7. Once the image is built, you can run a container using the following command: 
$ docker run -d -p 80:80 my-apache
This command runs a container using the image you just built and maps port 80 of the container to port 80 of the host machine. The "-d" flag runs the container in detached mode, backgrounding the process.
8. You can now access the Apache web server running inside the Docker container by opening a web browser and entering the IP address or hostname of your Ubuntu server.
By [Install Apache in Docker Container on Ubuntu 22.04](https://orcacore.com/install-apache-docker-container-ubuntu-22-04/)
, you gain several benefits. It allows for easy distribution and replication of the Apache environment, ensuring consistency across different servers. Docker also provides isolation, preventing conflicts with other software dependencies on the host machine. Additionally, it facilitates scalability and efficient resource management, as you can easily start or stop containers without affecting the host environment.
With this approach, you can quickly deploy and manage your Apache web server using Docker, streamlining your development workflow and making it easier to handle multiple instances across different environments.
Iterating through Arrays: forEach vs for...of
Tags: webdev, javascript, beginners, programming
Published: 2023-10-22 12:45:35

When working with JavaScript and array manipulation, understanding how to iterate through array elements is essential. Two of the most common approaches for this task are using `forEach` and `for...of`. Both have their advantages and disadvantages, and in this article, we will explore the differences between them with more complex examples.

## The `forEach` Method

The `forEach` is a built-in method for arrays in JavaScript that allows you to traverse each element in an array and perform a function on each of them. Its syntax is straightforward:

```javascript
array.forEach(function(element) {
    // Do something with the element
});
```

Advantages of `forEach`:
1. It's easy to read and write.
2. It's a natural choice for actions you want to perform on each element of the array.

Disadvantages of `forEach`:
1. It can't be easily stopped. If you want to exit the loop before traversing all elements, this can be challenging.
2. It's not suitable for element transformations, such as creating a new array based on existing elements.

## The `for...of` Loop

The `for...of` is a looping structure introduced in ECMAScript 2015 (ES6). It allows you to iterate over iterable values, such as arrays, strings, and maps, in a more flexible way. Here's how you would use `for...of` to iterate over an array:

```javascript
for (const element of array) {
    // Do something with the element
}
```

Advantages of `for...of`:
1. It can be easily stopped using the `break` statement.
2. It's useful for creating new arrays based on the elements of the original array.

Disadvantages of `for...of`:
1. The syntax can be slightly more complex compared to `forEach`.
2. It's not suitable if you need to access the index of the element in the array directly.

## When to Use Which?

The choice between `forEach` and `for...of` depends on the needs of your code. If you're doing something simple on each element of an array, `forEach` is a solid choice due to its simplicity. However, if you need more control over the loop or want to create a new array based on the original elements, `for...of` is the more flexible choice.

## Conclusion

Both approaches have their place in JavaScript, and the choice between `forEach` and `for...of` should be based on your specific needs. Both are powerful tools for working with arrays and can help make your code more efficient and readable. So, choose wisely and adapt to the context of your project.

I hope this article has helped clarify the difference between `forEach` and `for...of` when iterating through arrays in JavaScript. Remember that the choice between these methods should be made based on your code's requirements and desired outcomes.
MPDetector-Part 1: The Idea
Published: 2023-10-22 12:40:02

## Background
Several days ago, I came across an answer from Quora that seemed to be AI-generated. There, an idea popped into my head.
*What if I create an AI text detector that can even detect the paraphraser?*
I'm going to create this. And I will call this detector **MPDetector**.

## Example
Let's say I have a description of the 2022 FIFA World Cup generated by Bard.
> Argentina won the 2022 FIFA World Cup, defeating France in the final on penalties after the match was tied 3-3 after extra time. The match was played on December 18, 2022, at the Lusail Iconic Stadium in Lusail, Qatar. Argentina's victory was their third World Cup title, and their first since 1986. Lionel Messi was named the player of the tournament. The 2022 World Cup was held in Qatar from November 21 to December 18, 2022. It was the first World Cup to be held in the Arab world.

And now I paraphrased it with QuillBot.

> Argentina defeated France in the 2022 FIFA World Cup final on penalties after the score remained at 3-3 after extra time. The game took place in the Lusail Iconic Stadium in Lusail, Qatar, on December 18, 2022. With this victory, Argentina won their third World Cup and first since 1986. The competition's player of the year award went to Lionel Messi. Qatar hosted the 2022 World Cup from November 21 to December 18, 2022. The Arab world hosted the World Cup for the first time.

MDetector would detect that the text was generated by Bard and paraphrased by QuillBot.

## Possible?
*Is it possible for an AI to detect both the AI text generator and the paraphraser?*
Maybe. But it's undeniable that it will be a significant challenge, as I now need a huge amount of data collected from both the text generator and the paraphraser.

*This is my first post, by the way.*
Flower store app. Part 2. Strangeness out of nowhere
Tags: richresults, cache, bug
Published: 2023-10-22 12:33:27

While talks continue about the feasibility of an app for a flower store, I decided to just take a look - what kind of site is proposed to be embodied as an app?
Having run it through all known diagnostic tools, I found one very strange feature: the strange piece of code appears ONLY when checking it through Google's rich-results tester.
Example: look at source of this page - https://saholaflowers.com/. Screenshot of last few lines:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/cv2nsra1cn3ajf02ydq9.png)

And now the same page, viewed through Google tools: https://search.google.com/test/rich-results/result?id=foGWPW0ALJ5aOdsWqBcjPw

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/cxyqcg5pzu9zcwyyt5eh.png)

Do you see a new piece of code after the closing script tag?

I'll remind you, this is source code - there can't be a dynamically added JS DOM. But this piece of code only appears when viewed through this tool.

This piece of code has the site's old domain, saholany dot com. I have checked the WHOLE site, every file, the entire database - there is not a single mention of this old domain.

I've reset all the cache on the hosting, on the site, on the browser. But this code is still there.

Not only that, if I make changes to the site code (like adding a tag with the class test-tag-for-goole), the tool will see those changes - so it's not a Google cache or some other cached value, no:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/aslulzux1p6w09ycxhw7.png)

So what is that?

And even more important question, how do you clean this up? This is the first time I've encountered a situation where I can't find the reason for the code appearing on my own site....

Published: 2023-10-22 12:25:13

What is IoT Hub?
Azure IoT Hub - Microsoft
IoT Hub is a Platform-as-a-Services (PaaS) managed service, hosted in the cloud, that acts as a central message hub for bi-directional communication between an IoT application and the devices it manages. 

Step 1. Create an IoT Hub

- Go to your Azure Portal, on the dashboard, you will see IoT Hub, click on it.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/7upw5uehgogiih24zouf.png)

- On the IoT Hub page, click on create.
For your first time, you would be required to create a new resource group. Create a name for your IoT Hub also then click on Review + Create.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/csfxj4wk9a4f8tbqsd8d.png)

Click on Create and wait for it to successfully deploy.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pxc7z7uwgi3r8yup4svq.png)

After the deployment must have been completed, go to resource.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8yf2xn6rbsrm94nyauhv.png)

Step 2. Add an IoT device.
- Scroll down to the usage section and you will see that all message counts are zero. Click on the device section to add a device.
  
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/eelzz373otab9p3td3yt.png)

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/j2sr5y5tt2blxk1wcnut.png)

Give your IoT Hub device a name and save. When it must have saved completely, click on the device you just created.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/d8iuzz3xac3dq61ksq6n.png)

When you open the device, copy the primary connection string.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/3u1hfm6jn47md9ceq8pb.png)

Step 3. Test the device using the Raspberry Pi Simulator.
- What is a Raspberry Pi used for?
The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python.
Search Raspberry Pi online simulator on Google.
When the simulator comes up, check the code section in line 15. Clear everything inside the quote sign and paste your primary connection string, then run the code; you will notice that the red bulb that was not blinking before starts blinking. Then go back to the resource of your IoT Hub device, under the usage section and you will see that the message counts that were zero before have increased. This means that you did the right thing.

8. Sunday HTML day could've been better (Day 6)
Published: 2023-10-22 11:48:00

I had wanted to study at least 8 hours today. Been mentally preparing for it all week. This is how it turned out:

**|DURATION|**	**|WHAT I DID|**
8:30 - 9:00 am	Breakfast
9:00 - 9:30 am	a bit of relaxation, catching up on stuff
9:30 - 10 am	Practicing GitHub commits (30 mins)
10:30-13:45	Study HTML/CSS (3.5 hrs)
14:00-14:30	Lunch
14:30-16:30	Attempting challenges and practice exercises (2 hrs)
16:00-18:30	Personal matters
18:30-19:00	Dinner
19:00 - 21:00	Attempting challenges and practice exercises (2 hrs)
**TOTAL STUDY TIME|	8 HRS**

Yeah!

But I still feel I didn't accomplish much. Felt I was really slow and could've grasped things faster & better.

I did build 3 single-page HTML websites with basic CSS styling. It involved watching course videos, referring to W3Schools, asking questions to fellow students, and just trial & error.

I am confident with:

- Git commits
- Starting HTML files
- Basic sections, articles, ordered lists, unordered lists, upload images, connecting pages

Not very confident with:

- Div
- Classes
- Formatting classes in a separate CSS file
- Block formatting

Another reason I am not satisfied with the day is that I was unable to complete all the Week 1 background reading, practice exercises, and challenges :( Next is Week 2 and study is piling up! Tuesday is my next class and tomorrow (Monday) evening is all I have for the pre-class reading.

I must stay focused, do my best, utilize time well, and take 1 day at a time.

Good night.

Simplest way to use prisma with Aex
Tags: prisma, aex, typescript, node
Published: 2023-10-22 11:26:23

Prisma is the best orm tool for node.js so far.
And aex is the best web framework for node.js and typescript so far.
With Aex and Prisma, You can boost your application development speed with less code.
Here is a simple way to show you how easy it is to create a web server with aex and prisma.

### 1. Create a class with http request handler(s)

```ts
class HelloAex {
  @compact("/")
  public async hello(ctx:any) {
    const {
      prisma,
    }: {
      prisma: PrismaClient;
    } = ctx.scope.orm;
    const users = prisma.user.findMany({});
    ctx.res.json(users);
    return;
  }
}
```

### 2. Create a prisma client and it's middleware for aex


```ts

const prisma = new PrismaClient();
const prismaMiddleware = (function (prismaClient) {
  return async (_, __, scope) => {
    await prismaClient.$connect();
    scope.orm = {};  // @aex/core v0.18.4+ has built-in orm property.
    scope.orm.prisma = prismaClient;
  }
})(prisma);

```

### 3. Create Aex and start the server

```ts
const aex = new Aex();
let port = 8081;

// add prisma support
aex.use(prismaMiddleware);
// init http handlers
aex.push(HelloAex);


// start aex server
aex
  .prepare()
  .start(port)
  .then(() => {
    console.log("Server started at http://localhost:" + port + "/");
  })
  .finally(async () => {
    // disconnect prisma when server is closed.
    await prisma.$disconnect();
  });
```

### 4. Run the server with ts-node.

Save all the above code into a file we can name it `server.ts`， then we can run it with the following command.

```bash
npx ts-node server.ts
```
then we can have the following output:
```bash
Server started at http://localhost:8081/
```

### 5. github code
The above code needs some initial work, you can just download code from https://github.com/aex-ts-node/primsa-example
then run the following code:
```bash
git clone https://github.com/aex-ts-node/primsa-example
cd primsa-example/
npm i
npx prisma generate
npx ts-node server.ts
```
You can now boot an aex server with prisma backed.
