Published: 2024-06-20 08:33:47

*This is a submission for [DEV Computer Science Challenge v24.06.12: One Byte Explainer](https://dev.to/challenges/cs).*

## Explainer

**Concept: Recursion**

Recursion is a programming technique where a function calls itself to solve smaller instances of the same problem. It’s essential for tasks like tree traversal and factorial calculations due to its elegance and ability to reduce complex problems into simpler ones.

## Additional Context

Recursion is powerful but can lead to stack overflow errors if not managed carefully. Understanding recursion is fundamental in mastering algorithms and can enhance code readability and efficiency.
Create virtual host on nginx server(Ubuntu)
Published: 2024-06-20 08:30:34

The deployment of application on server is a very tedious task. From installation of nginx to creation of virtual host and linking of virtual host from /etc/nginx/sites-available to /etc/nginx/sites-ebabled. Without the enable of virtual host will not work.

Following are steps to create virtual host and make it enabled to work.

1. create a host file on location /etc/nginx/sites-available/{your_host_file}
Ex. /etc/nginx/sites-available/demo-app

2. Next add the following code in host file

`server {
    location / {
        proxy_pass http://localhost:4100;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}`

3. Now enable the host by following commnad

`sudo ln -s /etc/nginx/sites-available/demo-app /etc/nginx/sites-enabled/`
The Phishing Revolution: AI-Powered Deception Makes Us All Vulnerable
Published: 2024-06-20 08:28:12

Think you can spot a phishing email a mile away? Think again. Artificial intelligence is making these attacks more sophisticated and undetectable than ever before.
AI is being used to personalise phishing emails, crafting messages that appear to come from trusted sources and mimicking writing styles with uncanny accuracy. These emails can bypass traditional spam filters and exploit human emotions, tricking even the most vigilant users.
Recently, I conducted a training simulation where employees were presented with AI-generated phishing emails. The results were concerning – even tech-savvy individuals fell victim.
Here's the new reality: we can't solely rely on the ability to spot a suspicious email. Organisations need to go beyond traditional phishing awareness training. Consider implementing security awareness programs that leverage AI to simulate real-world attack scenarios. This will help employees develop a stronger sense of cyber resilience and be better prepared to identify and avoid these cunning attempts.
Is your organisation prepared for the next generation of phishing attacks? Let's discuss how AI-powered security awareness training can keep your employees safe.

Cross HTM/CSS compiler
Tags: webdev, email, html, css
Published: 2024-06-20 08:27:32

Hey all!

I've recently taken on a task at my company to build an email template. Naively, you might think it would be simple. However, I quickly realized that HTML/CSS support in email clients is:

- Outdated
- Inconsistent from one client to another

I'm considering the idea of a cross-HTML/CSS compiler that transforms standard HTML/CSS into versions supported by various email clients. This would allow you to code as usual without worrying about client-specific rendering engines.

Would this be useful for you?

Published: 2024-06-20 08:24:34



### Question title

How to avoid the outline being blocked when hovering the pie chart sector in VChart?  

  

### Problem description

The hover stroke of the pie chart sector is configured, but it will be obscured by other sectors  


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pf6irz7q8ag3i0lelp4v.png)



  

You can adjust the level of the element when hover, so that the hover element is always displayed above other sectors, which can avoid the problem of stroke obstruction  


```javascript
 pie: {
    state: {
      hover: {
        stroke: 'black',
        lineWidth: 4,
        zIndex: 1
      }
    }
  },
```

### Code example


```javascript
const spec = {
  type: 'pie',
  data: [
    {
      id: 'id0',
      values: [
        { type: 'oxygen', value: '46.60' },
        { type: 'silicon', value: '27.72' },
        { type: 'aluminum', value: '8.13' },
        { type: 'iron', value: '5' },
        { type: 'calcium', value: '3.63' },
        { type: 'sodium', value: '2.83' },
        { type: 'potassium', value: '2.59' },
        { type: 'others', value: '3.5' }
      ]
    }
  ],
  outerRadius: 0.8,
  valueField: 'value',
  categoryField: 'type',
  title: {
    visible: true,
    text: 'Statistics of Surface Element Content'
  },
  legends: {
    visible: true,
    orient: 'left'
  },
  label: {
    visible: true
  },
  pie: {
    state: {
      hover: {
        stroke: 'black',
        lineWidth: 4,
        zIndex: 1

          key: datum => datum['type'],
          value: datum => datum['value'] + '%'
        }
      ]
    }
  }
};

const vchart = new VChart(spec, { dom: CONTAINER_ID });
vchart.renderSync();

// Just for the convenience of console debugging, DO NOT COPY!
window['vchart'] = vchart;
```

The Rise of Ransomware 2.0: More Than Just Encryption
Published: 2024-06-20 08:21:47


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ynk2m80viuyigrprn2xj.png)Imagine this: you wake up to a digital nightmare. Your entire company network is locked down, but there's no ransom note demanding Bitcoin. Instead, the attackers have unleashed your most sensitive data – customer records, financial reports, internal communications – onto the dark web. Welcome to the era of Ransomware 2.0, where data destruction is the new extortion tactic.
Ransomware has evolved beyond simple data encryption. Hackers now aim for complete annihilation, applying a "double extortion" strategy that puts immense pressure on organisations. They not only hold your data hostage, but also threaten to expose it publicly, creating a PR disaster alongside the data recovery challenge.
In my experience helping companies navigate this new reality, one thing is crystal clear: traditional backup and recovery plans are no longer sufficient. Organisations need a holistic security approach that includes Data Loss Prevention (DLP) to monitor and restrict sensitive data movement, network segmentation to isolate critical systems, and Continuous Threat Detection and Response (CTDR) to proactively identify and stop attacks before they escalate.
Don't wait to become a victim. Invest in advanced security solutions and train your employees to identify phishing attempts and social engineering tactics. Remember, prevention is always the smarter (and less stressful) option compared to cure.

What Exactly Is a Database and How Does It Impact Us?
Published: 2024-06-20 08:13:17

In the realm of software development, databases are an indispensable technology that has become essential for every developer. With the advent of the big data era, the concept of databases has deeply embedded itself in the minds of people, becoming a hot topic of discussion in everyday life. So, what exactly is a database and how closely is it related to our daily lives?

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/m6yffqly492tdwrwqyv8.png)
Unveiling the Mystery of Databases
A database is a systematic way of storing data that efficiently organizes, manages, retrieves, and analyzes large volumes of structured and unstructured data. Its core value lies in providing fast and accurate data access services for various applications.

When you browse products on an e-commerce platform, the database silently records your browsing history and purchase behavior in the background, in order to recommend products that better suit your preferences. When you interact with friends on social media, the database records every like, comment, and share to optimize your social experience. In business operations, databases play a pivotal role by helping enterprises store customer information, sales data, inventory records, and more, thereby supporting decision-making with data.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gf9ibv5dltah71k0263t.png)
SQL Language and SQLynx
SQL (Structured Query Language) is a standardized programming language used for querying, updating, and managing data stored in databases. It defines data structures and provides mechanisms for data access, control, and optimization. SQL tools are software applications that execute these commands. These tools typically offer user-friendly interfaces that enable developers and database administrators to write and execute SQL queries, manage database structures, and optimize performance. SQL tools simplify the database operation process, thereby enhancing efficiency, making them indispensable in database management and development.

Next, this article recommends a rising star in the world of SQL tools—SQLynx. SQLynx is a high-performance database management software that offers comprehensive features commonly used in databases, including SQL history queries, import/export functionalities, automated test data generation, automatic SQL statement generation, and data comparison.

Pros & Cons of Git Worktrees
Published: 2024-06-20 08:00:00

One might wonder why you would use multiple Git worktrees if you can switch between branches and stash it whenever you change something?

Let me guide you through the enchanting world of Git worktrees within a Git repository. We'll unravel the mysteries of how they differ from conventional branching strategies and shed light on their potential to revolutionize our workflow.

**What are the advantages of Git worktrees?**

**1. Parallel development**
Worktrees enable developers to work on multiple branches simultaneously without the overhead of switching contexts in the same directory.

**2. Simplified context switching**
They reduce the need for stashing or committing work-in-progress changes to switch branches, making context switching seamless and less error-prone.

**3. Isolated experimentation**
Worktrees offers a sandbox environment for experimenting with new features or bug fixes without affecting the main or other development branches.

**4. Enhanced code review process**
You can easily check out and test different pull requests or branches in separate directories, improving the efficiency of the code review process.

**What are the disadvantages of Git worktrees?**

**1. Disk space consideration**
Each worktree is a full checkout of a repository branch, which can use considerable disk space, especially in large projects.

**2. Complexity for new users**
Worktrees can introduce complexity for those new to Git, requiring a deeper understanding of Git's internals to manage effectively.

**3. Potential for confusion**
Managing multiple directories can lead to confusion, especially in large projects with many branches.


But to fully understand the advantages and disadvantages of Git worktrees, you should know what the best practices of using it are. You can organize your workspace or monitor disk space.

How to Kill a Process Binding to a Specific Port in PowerShell
Tags: terminal, powershell, process, port
Published: 2024-06-20 07:56:06

If you frequently run into issues where a process is binding to a specific port and you need to free that port, PowerShell provides a convenient way to do this. In this blog post, we’ll walk you through how to create a custom PowerShell function that kills the process binding to a specific port.

## The Problem

Often, when working with web servers, databases, or other network services, you might encounter the "port already in use" error. This means that a process is currently using the port you are trying to bind your service to. Manually finding and killing this process can be tedious. Automating this task with PowerShell can save you time and hassle.

## The Solution

PowerShell has cmdlets that can help you identify and stop processes. We will use `Get-NetTCPConnection` to find the process ID (PID) using the port and `Stop-Process` to terminate the process.

### Step-by-Step Guide

### 1. Define the Function

We will create a function called `Kill-PortProcess` that takes a port number as a parameter and kills the process using that port.

```powershell
function Kill-PortProcess {
    param (
        [int]$Port
    )
    try {
        $processId = (Get-NetTCPConnection -LocalPort $Port | Select-Object -ExpandProperty OwningProcess)
        if ($processId) {
            Stop-Process -Id $processId -Force
            Write-Host "Process with ID $processId that was using port $Port has been terminated."
        } else {
            Write-Host "No process is using port $Port."
        }
    } catch {
        Write-Host "An error occurred: $_"
    }
}
```

### 2. Save the Function

To make this function available in all your PowerShell sessions, save it in your PowerShell profile script. You can edit your profile script by running:

```powershell
code $PROFILE
```

Copy and paste the function definition into your profile script and save the file.

### 3. Use the Function

Now you can use this function in any PowerShell session. For example, to kill the process using port 8080, you would run:

```powershell
Kill-PortProcess -Port 8080
```

### Conclusion

With this custom PowerShell function, you can quickly and easily free up ports by terminating the processes that are using them. This can be particularly useful for developers and system administrators who frequently run into port conflicts.

Feel free to customize the function to better suit your needs, and happy scripting!

I hope this post helps you manage your ports more effectively. If you have any questions or suggestions, please leave a comment below.
