Introducing the Mycelium Network Junior Developer Hour
Tags: webdev, beginners, codenewbie
Published: 2024-05-07 15:47:17

For almost two years I have been making a [podcast called the Mycelium Network podcast](https://schalkneethling.substack.com/s/the-mycelium-network-podcast) that forms part of the Mycelium Network community.

The primary goal of the community is to create a space for early-stage (entry-level, junior) web developers to find peers and mentors to help them through their learning journey. The primary goal of the podcast is to create a space where these same folks can share their stories and have a voice.

A place where they can share their ups, their downs, and their dreams. The ultimate goal is to open up opportunities to break into the industry and start to build their dream life.

So far, it has been mildly successful but has not achieved the goals I set out for it. With this in mind, I am pivoting how I am approaching this going forward. Instead of a pure audio podcast with me and a guest, this will now be a live-streamed event ~~every two weeks~~ once a month, known as the Mycelium Network Junior Developer hour.

Here is how it will work.

~~Every two weeks~~ Once a month on a Wednesday at 5 PM UTC I will host an hour-long live stream across YouTube, Twitch, and LinkedIn, [using Riverside.fm](https://riverside.fm/). I will invite another mentor to join me for the stream, but most importantly, I invite junior developers to join the stream.

As a junior developer, you can participate in the stream in several ways:

- Listen in
- You can contact me beforehand to express interest in sharing your story live on stream
- Bring your questions for us to answer hopefully
- You can do all this with your camera on or off and using your name or a pseudonym, whichever you feel most comfortable with.
- You can also email your questions or share your story, which we will read during the stream.

The stream will be recorded and made available on YouTube and as an audio podcast (wherever you listen to podcasts) a week after the live stream. My hope is that this more interactive form of the podcast will be more effective, garner more interest, and provide a better platform for junior developers to share their stories and be noticed.

The first Junior Developer Hour will be on ~~May 22~~ May 29 at 5 PM UTC and you can email me at juniordevhour@mechanical.ink to express interest in sharing your story live on the stream, share your story in text format, or send along your questions.

## Times in other regions

- 9 PM - Dubai
- 7 PM - South Africa
- 5 PM - United Kingdom
- 2 PM - Rio de Janeiro
- 1 PM - New York
- 11 AM - Denver, Colorado
- 10 AM - San Francisco

> Note: You will also be able to ask questions during the stream.

I look forward to experimenting with this new format, learning your stories, and building out the community. Comments, questions, suggestions? Please share them below.

Simplifying Data Transfer in PHP: The Power of DTOs
Tags: dto, php, data, json
Published: 2024-05-07 15:14:29

## Introduction

In the world of PHP coding, there’s a nifty tool called Data Transfer Objects (DTOs) that makes sharing data between different parts of your program a breeze. Think of DTOs as digital couriers that safely deliver information from one place to another within your app. Let’s dive into what DTOs are and why they’re so handy for PHP developers.

## What’s a DTO?

A Data Transfer Object (DTO) is like a neat little package that holds data meant to be moved around your program. Unlike regular objects, DTOs don’t bother with fancy tricks or business rules. They’re all about safely ferrying data from one spot to another, making sure nothing gets lost along the way.

## DTO vs. POPO

DTOs are a specialized version of Plain Old PHP Objects (POPOs). POPOs are simple PHP classes that don’t get bogged down with extra stuff like inheritance or complex features. DTOs take that simplicity and focus it squarely on moving data around efficiently.

## Why Use DTOs?

1. Keep Things Safe: DTOs make sure your data stays in the right format, reducing mix-ups and errors.
2. Easy to Understand: With DTOs, your data’s structure is crystal clear, making your code easier to read and work with.
3. Less Headache: Debugging becomes less of a puzzle when your data follows a clear path thanks to DTOs.
4. Ready for Growth: As your app evolves, DTOs make it easier to add new features without causing chaos in your code.

## Putting DTOs into Action in PHP

Let’s say you’re dealing with JSON data from a user’s request. With DTOs, handling that data becomes a piece of cake:

``` php
$json = file_get_contents('php://input');
$data = json_decode($json, associative: true);

$user = new UserDto($data['first_name'], $data['last_name']);
```
The _**UserDto**_ class is your go-to for managing user data, making sure everything stays organized and error-free.

## When to Use DTOs
DTOs are your best pals when:

1. You need to move data between different parts of your app.
2. Making sure data types match up and stay consistent is crucial.
3. Keeping your code neat and easy to manage is a priority.

## DTOs in PHP and Beyond
While it might be tempting to stick with arrays for handling data, DTOs bring a level of organization and reliability that can’t be beaten. They’re like having a reliable delivery service for your data, ensuring it gets where it needs to go without any hiccups.

## Conclusion
Data Transfer Objects (DTOs) might sound fancy, but they’re really just handy tools for keeping your data organized and your code clean in PHP. By using DTOs, you’ll save time, reduce errors, and set yourself up for smoother development as your app grows. Give DTOs a try in your PHP projects and see the difference they can make!

445. Add Two Numbers II
Tags: php, leetcode, algorithms, programming
Published: 2024-05-07 15:11:18

445\. Add Two Numbers II

Medium

You are given two **non-empty** linked lists representing two non-negative integers. The most significant digit comes first and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list.

You may assume the two numbers do not contain any leading zero, except the number 0 itself.

**Example 1:**

![sumii-linked-list](https://assets.leetcode.com/uploads/2021/04/09/sumii-linked-list.jpg)

- **Input:** l1 = [7,2,4,3], l2 = [5,6,4]
- **Output:** [7,8,0,7]

**Example 2:**

- **Input:** l1 = [2,4,3], l2 = [5,6,4]
- **Output:** [8,0,7]

**Example 3:**

- **Input:** l1 = [0], l2 = [0]
- **Output:** [0] 

**Constraints:**

- The number of nodes in each linked list is in the range [1, 100].
- <code>0 <= Node.val <= 9</code>
- It is guaranteed that the list represents a number that does not have leading zeros.

**Follow-up:** Could you solve it without reversing the input lists?

**Solution:**

```
/**
 * Definition for a singly-linked list.
 * class ListNode {
 *     public $val = 0;
 *     public $next = null;
 *     function __construct($val = 0, $next = null) {
 *         $this->val = $val;
 *         $this->next = $next;
 *     }
 * }
 */
class Solution {

    /**
     * @param ListNode $l1
     * @param ListNode $l2
     * @return ListNode
     */
    function addTwoNumbers($l1, $l2) {
        $s1 = new SplStack();
        $s2 = new SplStack();
        while($l1 != null){
            $s1->push($l1->val);
            $l1 = $l1->next;
        }

        while($l2 != null){
            $s2->push($l2->val);
            $l2 = $l2->next;
        }

        $sum = 0;
        $cur = new ListNode();
        while(!$s1->isEmpty() || !$s2->isEmpty()){
            if(!$s1->isEmpty()) $sum += $s1->pop();
            if(!$s2->isEmpty()) $sum += $s2->pop();

            $cur->val = $sum%10;
            $head = new ListNode(floor($sum/10));
            $head->next = $cur; // reconstruct
            $cur = $head;// moving on
            $sum /= 10;
        }
        if($cur->val >= 1 ){
            $return_value =  0? $cur->next: $cur;   
        }else{
            $return_value = $cur->next;
        }
        return ($return_value);
        //return $cur->val == 0? $cur->next: $cur;
    }
}
```

2816. Double a Number Represented as a Linked List
Tags: php, leetcode, algorithms, programming
Published: 2024-05-07 15:10:52

2816\. Double a Number Represented as a Linked List

Medium

You are given the `head` of a **non-empty** linked list representing a non-negative integer without leading zeroes.

Return _the `head` of the linked list after **doubling** it._

**Example 1:**

![example](https://assets.leetcode.com/uploads/2023/05/28/example.png)

- **Input:** head = [1,8,9]
- **Output:** [3,7,8]
- **Explanation:** The figure above corresponds to the given linked list which represents the number 189. Hence, the returned linked list represents the number 189 * 2 = 378.

**Example 2:**

![example2](https://assets.leetcode.com/uploads/2023/05/28/example2.png)

- **Input:** head = [9,9,9]
- **Output:** [1,9,9,8]
- **Explanation:** The figure above corresponds to the given linked list which represents the number 999. Hence, the returned linked list reprersents the number 999 * 2 = 1998.

**Constraints:**

- The number of nodes in the list is in the range <code>[1, 10<sup>4</sup>]</code>
- `0 <= Node.val <= 9`
- The input is generated such that the list represents a number that does not have leading zeros, except the number `0` itself.


**Solution:**

```
/**
 * Definition for a singly-linked list.
 * class ListNode {
 *     public $val = 0;
 *     public $next = null;
 *     function __construct($val = 0, $next = null) {
 *         $this->val = $val;
 *         $this->next = $next;
 *     }
 * }
 */
class Solution {

    /**
     * @param ListNode $head
     * @return ListNode
     */
    function doubleIt($head) {
        if ($head->val >= 5)
            $head = new ListNode(0, $head);

        for ($curr = $head; $curr != null; $curr = $curr->next) {
            $curr->val *= 2;
            $curr->val %= 10;
            if ($curr->next && $curr->next->val >= 5)
                ++$curr->val;
        }

        return $head;
    }
}
```
