How to Quickly Check Your Ubuntu Version
Published: 2023-10-03 01:36:23

The "Ubuntu Version Checker" is a Bash script designed to quickly and reliably determine the version of the Ubuntu operating system installed on a Linux system. 

This script is particularly useful for system administrators, developers, and users who need to identify the precise Ubuntu release running on their system.

## Usage:

1. Download the **check_ubuntu_version.sh** scriot from here:
[https://sourceforge.net/projects/check-ubuntu-version/](https://sourceforge.net/projects/check-ubuntu-version/
)

2. Make the script executable by running:

```
chmod +x ./check_ubuntu_version.sh

```
3. Launch it with:

```
./check_ubuntu_version.sh

```
The script will promptly display the Ubuntu OS name, version/release, and codename, making it easy to identify the specific Ubuntu distribution installed.

## Key Features:

### - Robust Detection: 
The script first checks for the presence of the lsb_release command, a standard utility for obtaining distribution information. If lsb_release is available, it uses this tool to extract the Ubuntu version and codename. If not, it falls back to an alternative method.

### - Detailed Output: 
The script provides a comprehensive and informative output. It not only displays the OS name, version/release, and codename but also separates each piece of information for clarity.

###  - Fallback Method: 
In the absence of lsb_release, the script reads information from the /etc/os-release file, a widely supported method for retrieving OS details on Linux systems. This ensures compatibility across various Linux distributions.

## Use Cases:

### - System Identification: 
System administrators can use this script to quickly identify the Ubuntu version on multiple servers, aiding in maintenance and troubleshooting tasks.

### - Compatibility Checking: 
Developers and software maintainers can use this script to verify the Ubuntu version on which their software is running to ensure compatibility.

### - User Information: 
Regular Ubuntu users can run this script to learn more about their system and its release details.

### Conclusion:

In summary, the "Ubuntu Version Checker" script simplifies the process of determining the Ubuntu version and provides detailed information in a structured format, improving system management and user awareness.

After going through all the emotions starting off and getting off the ground learning code, I can't help but ponder on a better way I could of went about my journey.

So here's my question for the community. If you could do things over, how would you go about your journey? What would you have done differently? I recently answered the same question in my blog [](https://trottiemcqueendev.hashnode.dev/play-to-learn-or-tutorials)
Linear Search Explained With Diagrams
Tags: computerscience, algorithms
Published: 2023-10-03 01:15:04


## Introduction:
When it comes to searching for a specific item in a collection of data, algorithms play a crucial role in efficiently finding what we need. One such algorithm, the Linear Search, is a fundamental and straightforward method. In this article, we'll explore the concept of Linear Search with the help of clear diagrams, making it easy to understand even for those new to programming.

### What is Linear Search?

Linear Search, also known as Sequential Search, is the simplest searching algorithm. It works by examining each element in a dataset, one by one, until a match is found or until every element has been checked.

### How Linear Search Works:

Imagine you have an array of numbers:

[70,40,30,11,57,41,25,14,52]


![Viusla Diagram](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pl8yldybwezcv34dqtjz.png)
<figcaption>Image from Javatpoint</figcaption>


And you want to find the number 41 within this array using Linear Search.

1. **Start from the Beginning:**
   Begin at the first element of the array, which is 70 in this case.

   

2. **Compare with the Target:**
   Compare the element you're currently examining (70) with the target value (41).


3. **No Match? Move On:**
   Since 70 is not equal to 41, you move on to the next element in the array (40).


4. **Keep Searching:**
   Continue this process until you either find the target (15) or reach the end of the array.

5. **Found It!**
   In this case, you find the target value (41) after examining the fifth element.


### Pseudocode for Linear Search:

Here's a simple pseudocode representation of Linear Search:

```
function linearSearch(array, target):
    for each element in array:
        if element equals target:
            return element found at index
    return element not found
```

### Advantages and Disadvantages:

**Advantages:**
- Simple to understand and implement.
- Works with unsorted data.

**Disadvantages:**
- Inefficient for large datasets.
- It may require checking every element before finding the target, making it slower than other algorithms for extensive lists.

### Conclusion:

Linear Search is a straightforward and easy-to-grasp searching algorithm. While it may not be the most efficient option for large datasets, it serves as a foundational concept in computer science and programming. The step-by-step diagrammatic representation should help you visualize how Linear Search operates, making it a valuable addition to your programming toolkit.
"Enhancing Text2page: Adding Markdown and Code Block Support" #LAB 3
Published: 2023-10-03 00:46:04

This week for my LAB-3, I am mainly working on using git to manage multiple simultaneous changes in a single project, and use git merges. 
I have created 2 issues
- [issue-10](https://github.com/Vishnudas2003/Text2Page/issues/1) : Adding Support for a Horizontal Rule in Markdown
- [issue-11](https://github.com/Vishnudas2003/Text2Page/issues/2) : Adding Support for Inline <code> Blocks and Fenced Code Blocks (Markdown)

**Issue-10: Adding Support for Horizontal Rules (Markdown):**
Un the Text2page project helps in rendering Markdown rules. Users found it difficult to produce aesthetically attractive and well structured HTML from documents from their Markdown files due to this restriction. 
The first step in solving the issue was to figure out the Markdown pattern for horizontal rules. Horizontal rules in Markdown are usually indicated by three hyphens, asterisks, or underscores, separated by spaces. As an illustration, ---, ***, or ___. 
In order to add support for horizontal rules, I had to improve the parsing procedure to recognize the Markdown pattern for them.
**Code Snippet:**
Here is a simplified code snippet that demonstrates the implementation of horizontal rule support in Text2page:

```
def create_html_from_markdown(input_file, output_dir, stylesheet_url=None):
    # ... (existing code)

    # Convert Markdown to HTML
    content = file.read()
    content_with_hr = parse_horizontal_rules(content)  # Custom function to identify and replace horizontal rules
    html_content = markdown2.markdown(content_with_hr)

    # ... (rest of the code)
```

**Issue-11 : Adding Support for Inline <code> Blocks and Fenced Code Blocks (Markdown)**
The Text2page project did not previously enable displaying markdown code blocks that were fenced and rendered inline. This restriction made it difficult for the users to efficiently add code snippets to the HTML documents they have been created from Markdown files. 
The following steps made up the implementation process:
The initial step was to determine the Markdown patterns that stand in for code snippets. Markdown normally uses single backticks (') for inline code and three backticks (''') for fenced code blocks, which may or may not be followed by the language identification. 
Here is a simplified code snippet that demonstrates the implementation of inline <code> blocks and fenced code blocks support in Text2page:

```
def create_html_from_markdown(input_file, output_dir, stylesheet_url=None):
    # ... (existing code)

    # Convert Markdown to HTML
    content = file.read()
    content_with_code_blocks = parse_code_blocks(content)  # Custom function to identify and render code blocks
    html_content = markdown2.markdown(content_with_code_blocks)

    # ... (rest of the code)
```

title: Splendid Astro Spacing — A Tailwind Utility for Astro

When using Tailwind with Astro, you’ll notice that [Tailwind’s space utilities](https://tailwindcss.com/docs/space) stop working when you use it with Astro Components or Slots .

```astro
<!-- Doesn't work when using with Astro components and slots -->
<div class='space-y-4'>
  <Component client:load />
  <Component client:load />
</div>
```

The reason is simple. I’ve wrote about the cause in [a previous article](/blog/overcoming-astro-styling-frustrations) and how to fix it.

You can read that article for more information, but the gist is:

1. Astro components and slots wrap it’s contents in a div that has `display: contents`
2. The `* + *` selector, which Tailwind uses for its space utilities, cannot target the elements within these Astro components and slots

## A simple fix

Fixing this is simple. We just have to modify Tailwind’s space utilities with a plugin — so they can dive one level beyond Astro’s components and slots.

I’ve created this plugin and added it as part of Splendid UI. You can install it Splendid UI like this.

```shell
npm install splendid-ui
```

Then you can use the plugin in your Tailwind config file like this:

```js
module.exports = {
  plugins: [require('splendid-ui/tailwind/plugins/astro-space.cjs')],
}
```

(I know the path looks long and complicated right now. It's something I'll simplify in the future as Splendid UI becomes more mature. For now, just enjoy something that works! 🙃).

That’s it!

Receiving messages from socket.io in Angular
Tags: socketio, angular
Published: 2023-10-02 23:51:14

## Scenario

You have a flask server serving websocket via socket.io and need to connect from an Angular client.

## Solution

In Angular:
1. Create a module (optional)
1. Create a websocket service inside that module
1. Inject the websocket service into the component who will handle the messages
1. Create the methods to handle messages inside that component

### Create a module and websocket service

Create a standard module and a standard service
```sh
ng g m ws
ng g s ws/websocket
```

You must create a service consisting only of an instance of a socket connection. We need the service to keep only one connection to the server at the beginning of service. Don't forget to enable CORS on server. Your websocket service will look like this:

```js
// /app/ws/web-socket.service.ts
import { Injectable } from '@angular/core';
import { io } from 'socket.io-client';

@Injectable({
  providedIn: 'root',
})
export class WebSocketService {
  private socket: any = undefined;

  constructor() {
    if (!this.socket) {
      this.socket = io('http://localhost:5000/');
    }
  }

  public getSocket() {
    return this.socket;
  }
}

```

Don't forget to install [socket.io-client](https://www.npmjs.com/package/socket.io-client) on your Angular project.

### The client component

You must then inject your service into a component who will use the connection and intercept the messages.

```js
/ //app.component.ts
import { Component } from '@angular/core';
import { WebSocketService } from './ws/web-socket.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
})
export class AppComponent {
  socket: any;
  messages: string[] = [];

  // Inject the service
  constructor(private webSocketService: WebSocketService) {
    this.socket = this.webSocketService.getSocket();

    // in this component you define what to do
    // with received event of type 'message'
    this.socket.on('message', (data: any) => {
      this.messages.push(data);
    });

    // when receiving a 'connect' event, send a message to server
    this.socket.on('connect', () => {
      const message = 'myevent';
      this.socket.emit(message, { data: "I'm connected!" });
    });
}
```

Using this approach, you can connect to a server and define what to do with the received messages, of emit new messages to the server in a simple way, separating concerns as a service and a controller.

My #100DaysOfCode Challenge
Tags: 100daysofcode, webdev, beginners, career
Published: 2023-10-02 23:04:01

### Past
I have had a really long, bumpy relationship with coding. I'm a naturally fast learner, so when I run into something with as many hurdles as coding, I've never had enough grit to make it through. Or at least, that's what I tell myself.

At the earliest stages of my journey, I had online profiles on chat sites that I customized with HTML and CSS before I even really understood what those were.

When I was in high school, I traded my Physics courses for Computer Science courses. I got to learn web design and make my own games instead of doing math on paper, what a dream! At the peak of my high school tech career, I used a Logitech webcam and my own API to design something similar to a Ring doorbell before those really got popular. 

Nowadays, I know enough about these technical topics to hold a conversation, but if you actually pressed me about some of them and held my feet to the fire, I probably wouldn't be able to give you solid answers. For my fellow Americans, if you had Spanish classes in high school and haven't spoken the language since, you'll know how I feel: a stuttering, bumbling mess.

### Future
So, I want to make an effort to fix that. How are things going to change? 

I've always struggled with motivation, but I've never struggled with passion. That, I've got buckets full of. So, let's take all that passion and turn it into something fruitful.

You all may have heard of the [recent round of layoffs](https://dev.to/devteam/dev-team-update-22c9) at Forem last week. While I was unfortunately one of the unlucky few impacted, I'm not going to let that stop me from connecting with over one million of you amazing people each and every week. 

I'm feeling motivated enough to do 100 Days of Code this October, so let's see how it'll turn out. With this post, I'm committing myself publicly to the challenge. Maybe a true developer will be born out of this venture.
{% embed https://100DaysOfCode.com %}

I think this time, I have a few major motivations that will make the difference: 
1. I'm already at the best place to be a CodeNewbie: dev.to
2. I have dream projects I want to be able to turn into reality. 
3. I'm willing to take it slow and understand that there are going to be a lot of things that I don't get the first go around. 

You can follow along with my daily progress on Twitter: {% embed https://twitter.com/bethenb1 %}

I'll post weekly here so I don't spam you too much - and just to make it easier on the ol' wrists. 15 posts is a lot less than 100 posts. 

If anyone has been waiting to make the effort to learn how to code, this is your sign! I'm following [The Odin Project](https://www.theodinproject.com), so you can feel free to learn along with me at your own pace. I'm inspired by all of you and hope that I can inspire some newbies myself along the way. 

If I get anything wrong, feel free to leave a helpful comment! See you soon! 💕
