Exploring the Power of Redux in Modern Development
Tags: redux, react, programminghero, assignment
Published: 2023-08-25 05:42:15

In the fast-paced world of modern development, staying up-to-date with the latest technologies is crucial. Recently, I delved into the world of Redux, a state management library for JavaScript applications. The experience has been nothing short of transformative.

Redux, with its unidirectional data flow and centralized state management, brings a new level of organization and efficiency to complex applications. Its core principles of having a single source of truth and state changes being handled predictably through actions, reducers, and stores, have reshaped how I approach app architecture.

One of the most striking benefits of Redux is its ability to maintain a clear separation between components and data management. This separation enables smoother collaboration among team members, as it fosters a shared understanding of how data flows and where changes occur. Additionally, debugging becomes significantly easier, as the single source of truth minimizes unpredictable behavior.

As I implemented Redux, I found the concept of immutability to be a game-changer. By treating state as immutable and producing new state objects with each change, Redux promotes data integrity and prevents unexpected side effects. This approach enhances the stability and predictability of applications, a vital factor in delivering high-quality software.

In conclusion, my journey into the realm of Redux has been enlightening. Its elegant approach to managing state and data flow has opened new doors in terms of code maintainability and collaboration. While the learning curve can be steep, the benefits in terms of organization, predictability, and debugging are invaluable. As I continue to explore Redux and integrate it into my projects, I am excited to witness the positive impact it brings to the world of modern development.

Appendixes
Introduction to ADBMGR
Briefs on ADBMGR
adbmgr is a management tool for AntDB cluster, which has all the functions of managing AntDB cluster, including the initialization, starting and stopping of AntDB cluster, the parameter setting of all cluster nodes, and the expansion and contraction of AntDB cluster.
AntDB cluster can be deployed on multiple machines. adbmgr needs to start a process called agent on each host in order to achieve the function of managing AntDB cluster. adbmgr achieves the management of AntDB cluster through the agent process. adbmgr includes the management of the agent process.
For example, if a user executes a start command to start a cluster node on host1, adbmgr will pass the start command to the agent process on host1, and the agent process will execute the start command; then the agent will pass the execution result of the start command to adbmgr and display it as the execution result of the user command. So, an agent process should be started on each host where AntDB cluster is located.
For the purpose of managing AntDB cluster, there are 4 tables in adbmgr, which are used to store the basic configurations of AntDB cluster, and all the operation commands of adbmgr are operated based on these 4 tables, so it is necessary to introduce these 4 tables in detail.
Host table

The host table is used to store the host and agent process information of the deployed AntDB cluster. The following figure shows the host table with 2 host information:
For example: Connect to adbmgr and execute:

```
postgres=# list host; 
```
The output results are listed in the following table:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/axc9sbqeouu21k7c86nl.png)
The detailed explanation of each column of the host table is as follows:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/spbzpdvzl5laxbes0g9l.png)
•Use the add host command to add a row to the host table.
•Use the alter host command to modify a field in a row.
•Use drop host to delete a row in the host table.
•Use the list host command to display the information of the specified host in the host table.
For details of the above commands, please refer to the commands related to the host table in Chapter 4.
The following are examples of commands commonly used to operate on the host table:

```
add host localhost1( user=gd, protocol=ssh, address='10.21.20.175', agentport=10906, adbhome='/data/antdb/app'); 
alter host localhost1(adbhome='/opt/antdb/app'); 
drop host localhost1; 
list host; 
```
Why can '=' be used for C structure assignment?

Why can '=' be used for C structure assignment?
-----------------------------------------------

When it comes to C programming, the '=' operator is widely used for variable assignment. However, you might be surprised to learn that it can also be used for assigning values to C structures. In this article, we will explore why the '=' operator can be used for C structure assignment and how it works.

In C, structures are used to group related data together. They allow you to define your own data types, combining different variables of different types into a single entity. To assign values to a structure, you can make use of the '=' operator, just like you would for assigning values to variables.

When you use the '=' operator for structure assignment, it copies the contents of one structure into another. This means that all the members of the source structure are copied to the corresponding members of the destination structure. It's important to note that this is a shallow copy, meaning that if your structure contains pointers or dynamically allocated memory, only the addresses will be copied, not the actual data.

Let's take a look at an example to better understand how structure assignment works:

 

    
        struct Person {
            char name[50];
            int age;
        };
        
        int main() {
            struct Person person1;
            struct Person person2;
            
            strcpy(person1.name, "John Doe");
            person1.age = 30;
            
            person2 = person1; // Structure assignment
            
            printf("Name: %s
    ", person2.name);
            printf("Age: %d
    ", person2.age);
            
            return 0;
        }
        

 

In this example, we have defined a structure called 'Person' with two members: 'name' and 'age'. We create two instances of this structure, 'person1' and 'person2'. Using the '=' operator, we assign the values of 'person1' to 'person2'. As a result, 'person2' now contains the same values as 'person1'.

Using the '=' operator for structure assignment can be quite convenient, especially when dealing with complex data structures. It allows you to easily copy the contents of one structure to another without having to manually copy each member. However, it's worth noting that if you have structures with dynamically allocated memory, you should implement a custom assignment function to ensure proper memory management.

So, next time you need to assign values to a C structure, don't forget that the '=' operator can come to the rescue, making your code more concise and readable.

It's pretty easy to set up GitHub action with AWS EC2 for deployments using SSH key, follow these 3 breakdowns to implement the pipeline.

## 1. Generate SSH Key
```sh
cd ~/.ssh
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
```
Enter file name: "key_name"
`ls` and list out files of the .ssh folder, you should be seeing "key_name" and "key_name.pub"

- Add public key to authroised keys
```sh
cat github-actions.pub >> ~/.ssh/authorized_keys
```

For detailed information on SSH Key generation process check this reference: https://zellwk.com/blog/github-actions-deploy/

## 2. Set Github Secrets
SSH_PRIVATE_KEY: private key that we created on ec2
HOST_NAME / IP_ADDRESS: Elastic IP or IP of EC2
USER_NAME: user name of the ec2 user.


## 3. Create a branch_name.yml ( for `dev` branch `dev.yml` ) file under .github/workflows

Update the dev to your branch name

```yml
name: Deploy

on:
  push:
    branches: [ dev ]

jobs:
  Deploy:
    name: Deploy to EC2
    runs-on: ubuntu-latest
    
    steps:
      - uses: actions/checkout@v2 
      - name: Build & Deploy
        env:
            PRIVATE_KEY: ${{ secrets.SSH_PRIVATE_KEY }}
            HOSTNAME: ${{secrets.SSH_HOST}}
            USER_NAME: ${{secrets.USER_NAME}}
      
        run: |
          echo "$PRIVATE_KEY" > private_key && chmod 600 private_key
          ssh -o StrictHostKeyChecking=no -i private_key ${USER_NAME}@${HOSTNAME} '

              # Now we have got the access of EC2 and we will start the deploy .
              cd /home/ubuntu/<PROJECT_DIRECTORY> &&
              git checkout dev &&
              git fetch --all &&
              git reset --hard origin/dev &&
              git pull origin dev &&
              sudo npm i &&
              sudo npm run build &&
              sudo pm2 stop ./dist/index.js &&
              sudo pm2 start ./dist/index.js
              '
```

Part 3: Ensuring Data Integrity: Unit and Integration Testing in GoLang RestAPI with MariaDB
Tags: go, mariadb, api, unittest
Published: 2023-08-25 04:25:37

Testing is a critical aspect of software development, ensuring that your application functions as expected and data integrity is maintained. In this article, we'll explore writing unit tests and integration tests for your GoLang RestAPI project with MariaDB. This rigorous testing approach guarantees the reliability of your codebase.

## Section 1: The Importance of Testing in Software Development

Testing prevents defects, improves code quality, and enhances user satisfaction. Unit tests isolate individual components, while integration tests ensure these components work together seamlessly.

## Section 2: Writing Unit Tests for GoLang RestAPI

Unit tests verify the functionality of individual functions or methods. Use the built-in `testing` package to write unit tests in GoLang.

Example unit test:

```go
func TestAddUser(t *testing.T) {
	db, mock, _ := sqlmock.New()
	defer db.Close()

	repo := UserRepository{db: db}

	mock.ExpectExec("INSERT INTO users").WillReturnResult(sqlmock.NewResult(1, 1))

	user := User{Name: "Alice", Email: "alice@example.com"}
	err := repo.AddUser(user)
	if err != nil {
		t.Errorf("Error adding user: %v", err)
	}
}
```

## Section 3: Conducting Integration Tests with MariaDB

Integration tests ensure that different components of your application work harmoniously. Use a test database and the same SQL queries as in production.

Example integration test:

```go
func TestGetUsers(t *testing.T) {
	db, mock, _ := sqlmock.New()
	defer db.Close()

	repo := UserRepository{db: db}

	rows := sqlmock.NewRows([]string{"id", "name", "email"}).AddRow(1, "Alice", "alice@example.com")
	mock.ExpectQuery("SELECT id, name, email FROM users").WillReturnRows(rows)

	users, err := repo.GetUsers()
	if err != nil {
		t.Errorf("Error getting users: %v", err)
	}

	if len(users) != 1 {
		t.Errorf("Expected 1 user, got %d", len(users))
	}
}
```

## Section 4: Running Tests and Ensuring Data Integrity

Use the `go test` command to run tests. For integration tests, consider using a Dockerized MariaDB instance to maintain a clean test environment.

## Section 5: Conclusion

Unit and integration testing play a pivotal role in ensuring your GoLang RestAPI project functions flawlessly and maintains data integrity. Thorough testing enhances code reliability and provides a safety net for future development. In the final article of this series, [we'll explore running your tests in a continuous integration (CI) environment.](https://dev.to/suranisaunak/part-4-continuous-integration-for-confidence-running-tests-in-ci-with-golang-restapi-and-mariadb-4296)

**Trust Issues**

It's now late in 2018 and I have my machine. Now what. Google, YouTube, Reddit, everything you can think of. Quite quickly I learned that there is an amazing amount of information out there. I also learned that sorting through it when you have no idea what you're looking at is really, stupidly hard. This is a common anecdote, but I really was trying to reconcile why some people called it JavaScript while others called it just Java. That's how **not** in-the-know I was.

Video by video, article by article, I was finally able to figure out what front end and back end referred to; that Java and JavaScript were **not** the same thing. And while some issues were straightened out, others emerged. Learn Angular! Wait, no maybe React? Relational databases are the standard, but you have to know MongoDB to be marketable. HTML sucks so you should just use Pug or Handlebars. CSS is stupid and confusing, just use Sass. Have we mentioned React yet?

*Alright, I found information... now which information can I trust?*

Developers come to different conclusions here; I recognize and respect that. Here's what it boiled down to for me: trust the people and organizations who stress and teach the basics, then decide where to go from there.

Very early on I knew that front end was where I wanted to be. I began seeing freeCodeCamp, Codecademy, bento, and even Treehouse (this was pre-2021 layoffs). I finally discovered MDN. And then I was off. 

In retrospect, this was the correct path for me (and, I suspect, for many coders around my time and in current time). Trust the foundational information. I hammer this when I mentor new developers. **_If you can write an interactive, accessible, functional website with just index.html, styles.css, and main.js, everything else will be icing on the cake._** And good employers will recognize that.

It wasn't just articles, learning platforms, and YouTube video though! Podcasts became by escape. If I had bashed my head into the keyboard for several hours trying to do the freeCodeCamp Intermediate Algorithms one after the other, I would close the laptop and find somewhere to chill down with a podcast. Syntax.fm, CodeNewbie, JavaScript Jabber, JS Party; I could list quite a few more. Combining all of those resources to make learning both passive and active was an extremely powerful approach.

It's a pity if you don't know about Wordle Unlimited!
Published: 2023-08-25 03:28:44


[Wordle Unlimited](https://wordleunlimited.one) is an unofficial version of Wordle, a world-famous vocabulary game. In this article, we will introduce you to Wordle Unlimited and how to play it.Wordle is a simple but fascinating game that requires you to guess a secret word of five letters in six attempts. After each guess, the fields change color to tell you whether you're approximate or completely wrong. If the text box is green, it means that the letter is right and in the right position. If the box is yellow, it means the letter is right but in the wrong position. If it's gray, it doesn't appear in the secret word.
 Josh Wardle is a British software developer who created Wordle. This game has attracted millions of players around the world because of its excitement and challenge. However, Wordle only allows you to play once a day, and the word secret also has only five letters.
 That's why Wordle Unlimited was born. Wordle Unlimited is an unofficial version of Wordle, created by an independent group of developers. In Wordle Unlimited, you can play with new words every time without having to wait a day like Wordle usually does. You can also customize the length of the word, from 4 to 11 letters, to increase the challenge. In addition, you can create your own games with words of your choice and share them with your friends to guess. Wordle Unlimited has a simple and easy-to-use interface. You just enter the words you think are correct and get suggestions about the location and color of the letters. You have six guesses for each word, and if you don't, you can click on the "Show answer" button to see the answer. Wordle Unlimited is a great way to train your vocabulary and logical thinking. You can visit the Wordle Unlimited website to play for free.
Why Boilerplate Projects are Not BAD
Tags: php, webdev, javascript
Published: 2023-08-25 02:53:08

Back in 2016, I had a package which was called LaraCogs. It was initially a boilerplate app. Then grew into a tool that added various files and adjusted a basic Laravel app. But due to consistent changes to Laravel's base app, it became cumbersome to maintain the package. My needs kept changing, so I scraped LaraCogs and put together a basic boilerplate app again. So I built Scaffold, and I'd like to detail why I think boilerplate projects are not bad.

##### Maintenance

Packages can be hard to maintain when built around third-party elements with consistent changes. Instead of making a few updates, you have to explore the impact of those updates on deeper stub files and the patterns they follow etc. I'm a big fan of Laravel Shift, which allows me to update projects of any size quickly. So running Laravel Shift on Scaffold takes all of 5 minutes tops. This process lets me examine those changes and apply them to any app which was based on Scaffold.

##### Improvements

Similar to the maintenance benefits, I can easily make adjustments to Scaffold, and when these improvements are obvious and beneficial to other apps, I can quickly extract them and apply them to the other projects. This is very beneficial when exploring new dependencies. Its easy to place something inside a tiny app you know very well and then carry that forward versus having to examine its impact in a package, spin up a new Laravel instance, run the package, and test the effect on the app.

##### Experiments

I use Scaffold for all sorts of experiments, testing ideas, testing integrations testing UI adjustments. This is the most significant benefit of a boilerplate project versus the LaraCogs package or things like Laravel presets. Presets and starter kits are handy tools but are a giant pain when rapidly testing and tinkering with a new idea. I can explore something in minutes on Scaffold and take those ideas to a new or old app, or leave them in Scaffold when needed.

The development world created an odd stigma around boilerplates with the power of packages propagating through all development languages (Mostly PHP and JavaScript are what I'm looking at). The only downside to boilerplates is when you let them become stagnant as if they are perfect and no longer require updates. But a good boilerplate is no different than a real-world MVP. It still takes effort and maintenance to keep it in good standing.
