Published: 2024-05-27 10:30:39

On May 27 2024, I encountered a daily Leetcode challenge entitled 

> Special Array With X Elements Greater Than or Equal X 

This challenge is relatively easy and quite friendly for beginners to practice. Because I'm learning Golang, I implemented it using that language.

For the question link, you can go to the following [page](https://leetcode.com/problems/special-array-with-x-elements-greater-than-or-equal-x).

![Example questions](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jjsv7zhh44j62kj66ek4.png)

## Solution
First of all, let's define the function.

```
func specialArray(nums []int) int {

}
```

Then, initiate the loop and associated dependent variables such as x and count into the function.

```
func specialArray(nums []int) int {
    for i := 1; i <= len(nums); i++ {
        x := i
	    count := 0
    }
}
```

Next, loop back over the nums array to compare whether each element is greater than x, if yes, add it to the count variable.

```
for _, v := range nums {
	if v >= x {
		count++
	}
}
```

Finally, check whether count is the same as x, if it is, immediately return x. However, if not, at the end of the function add return -1.

```
if count == x {
	return x
}
```

Complete code:

```
func specialArray(nums []int) int {
	for i := 1; i <= len(nums); i++ {
		x := i
		count := 0

		for _, v := range nums {
			if v >= x {
				count++
			}
		}

		if count == x {
			return x
		}
	}

	return -1
}
```
Laravel 10 API application with necessary functions pt 2.
Tags: laravel, php, windows, github
Published: 2024-05-27 10:27:32

**Environment:** Windows 10

**Necessary prequisites (knowledge):** VS Code, Composer, Terminal, Git bash, GitHub, Postman, MarkDown, XAMPP (also serves my MySql database), environmental variables (or .env), Blade, SPA, Sanctum, Passport

If you require further details, please feel free to add in comments.

**Nice to know:** If you don't see a change take effect, try stopping the server, and running this to clear cache and config:
`php artisan config:cache` 
When you've made changes in your .env file, you have to stop the server, run this and restart the server, for the changes to take effect.
Same goes to route changes:
`php artisan route:cache`

---

## Project Settings
There are plenty of knowledge on the Laravel documentation (https://laravel.com/docs/11.x/configuration), please feel free to explore. 
I have changed the language just for safety. 
`'faker_locale' => 'en_UK',`
My default time zone is UTC, which is correct, you may change this in config/app.php
You may change the .env APP_NAME, but don't use spaces or special characters.

## Database
I use mysql, and created a local database called L10Schema (case insensitive). I am going to connect the app to this database by editing my .env file like this: 

```
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=l10schema
DB_USERNAME=root
DB_PASSWORD=
```
To be able to keep my database in sync at all times with my code, table schemas and fields/columns, I'm going to run 
`php artisan migrate`
and from now on, when there is a database schema change, I repeat this.
(You can either ctrl+c to stop the php artisan serve code from running while you run this, or just open a new split command prompt and put it in there. )
To check if the migration ran successfully, open your database and see the new tables that's been created by Laravel.

## Current frontend page
The page you see on http://127.0.0.1:8000/ is called a view. This is the resources\views\welcome.blade.php file, that shows where the blade frontend files should be stored if you decide to use blade for your frontend. We aren't doing frontend in this blog post.

Don't forget to git commit and git push to store your working app. From this point it is recommended to create a new branch for changes, since what works for me might not work for you.

Enhancing Security in React with External Script Loading
Tags: react, nextjs, websecurity, javascript
Published: 2024-05-27 10:00:30


Developing dynamic and secure web applications using React and Next.js can often involve integrating third-party scripts. At [itselftools.com](https://itselftools.com), with our experience building over 30 apps using Next.js and Firebase, we've honed strategies that ensure safety and efficiency. One critical aspect involves the secure inclusion of external scripts, avoiding inline scripts to enhance security. This article explains a specific code snippet to achieve this purpose effectively.

## The Code Snippet
```jsx
// 7. Prevent inline scripts when using external scripts
function ExternalScripts() {
  return (
    <Script nonce={cspNonce} src="https://external.com/script.js" strategy="afterInteractive" />
  );
}
```
## Understanding the Code
This React component utilizes the `<Script>` tag from Next.js to load an external script. The key properties included are:

- **src**: Specifies the URL of the external script (`https://external.com/script.js`).
- **nonce**: A security token (here referred to as `cspNonce`) that aligns with the Content Security Policy (CSP) to prevent Cross-Site Scripting (XSS) attacks by ensuring the script is from a trusted source.
- **strategy**: Allocated as `afterInteractive`, which loads the script after the page has become interactive, balancing performance and functionality.

## Security Implications
Using the `nonce` attribute is crucial for enhancing CSP implementation, wherein it allows specific scripts to run while others, potentially harmful, do not execute. This approach is particularly beneficial in a React environment where inline scripts could make the application vulnerable to XSS attacks. By ensuring that scripts load after the application becomes interactive, it also optimizes the user experience without compromising security.

## Practical Applications
For those developing applications requiring high interactivity and integration with external APIs or libraries, this method proves invaluable. It ensures that the integration is secure, maintainable, and does not degrade the performance of the application.

## Conclusion
Understanding and implementing secure script loading practices is essential for modern web development. If you are interested in seeing this approach in action, explore some of our applications like [image compressor](https://online-image-compressor.com), [word search tool](https://find-words.com), and [language translator](https://translated-into.com), where robustness and performance meet user-friendly interfaces. These implementations demonstrate how securely managing external scripts can significantly contribute to robust web applications.

Thank you for exploring this aspect of React and Next.js with us at itselftools.com! Enhance your applications by considering these secure script-loading practices in your next project.

Nestled in the heart of the city, Klarity Eyecare Hospital boasts a state-of-the-art facility equipped with the latest advancements in eye care technology

https://www.klarityeyecare.com/retina-and-uvea

RETINA SPECIALIST IN LUCKNOW
WHAT IS RETINAL DETACHMENT?

Retinal Detachment is a condition in which the retina gets separated from the layer that contains blood vessels, the “choroid” leaving the retina without oxygen and nutrients. This puts the eye at risk of permanent vision loss unless appropriately treated by a trained retina specialist in Lucknow.

WHAT CAUSES RETINAL DETACHMENT?

Holes or tears occur in the retina and lead to the leaking of eye fluids and the separation of the retina from the underlying tissues. These tears can be caused by trauma, severe nearsightedness, or separation of the gel that tills the retina inside your eye from the retina
A pull on the retina may also occur if long-standing inflammation, uncontrolled diabetes, or scarring of the retina after some previous surgery.
