1,905,524 | Tailwind CSS or Styled Components? | The world of front-end development is vast as we all know and it consists of many ways to solve... | 0 | 2024-06-29T11:30:56 | https://dev.to/eyesaidyo/tailwind-css-or-styled-components-1dj3 | webdev, css | The world of front-end development is vast as we all know and it consists of many ways to solve different problems, one of which is styling with CSS. In my years using React predominantly for building UI components, various approaches to styling have appealed to me and in this article, I would like to make a case for two of my favorites. These two technologies solve the issue of styling components with CSS from two different points of view, my aim here is to present you with adequate information to make a sound decision as you pick your poison.
## The Case For Tailwind CSS
Tailwind is a CSS framework that simplifies styling your components into declaring some already-prepared class names. These class names contain trusty, well-tested style declarations that translate well into any component you are building. You can get a breakdown of these class names in their documentation (which is excellent by the way!) [here](https://tailwindcss.com/docs).
Here is a simple code-snippet to explain how this works:
```
<p class="text-lg font-medium">
“Tailwind CSS is the only framework that I've seen scale
on large teams. It’s easy to customize, adapts to any design,
and the build size is tiny.”
</p>
```
In the snippet above, the class names "text-lg" and "font-medium" are specifically provided by the CSS framework under the hood so you do not need to write out your own style declarations all you need do is state a class name they have already provided! For example, "text-lg" translates under the hood to:
`font-size: 1.125rem; /* 18px */
line-height: 1.75rem; /* 28px */`
As you can see, this approach to writing CSS simplifies things a lot in the following ways:
- It limits the amount of CSS files you need to make and removes the need for writing lengthy style declarations.
- You can see both your components and the styles without the need to go back and forth between files.
- This is much quicker to write and you can churn out components in record time once you know the docs.
If you need a project done quickly, especially if said project is concise, Tailwind would probably be my recommendation. It is lightweight, easy to use, and set up. The major drawback would be readability especially if it contains a lot of class names; you could run into some issues debugging especially if your knowledge of core CSS isn't at a great level.
## The Case for Styled Components
If you have ever built large projects with lots of moving parts and CSS, I'm sure you can't stress enough the importance of separating concerns to avoid style clashes. As codebases get larger, debugging gets more difficult. In such a scenario, you'd need a CSS solution that allows you to get meticulous about keeping certain style declarations fixed only to the scope of a particular component and hidden from the global context of your styling.
This is where Styled Components comes in. It is a CSS-in-JS solution to styling that enables you to write CSS right inside your JS component.
```
const Button = styled.a`
background: transparent;
border-radius: 3px;
border: 1px solid var(--accent-color);
color: var(--accent-color);
display: inline-block;
margin: 0.5rem 1rem;
padding: 0.5rem 0;
transition: all 200ms ease-in-out;
width: 11rem;
&:hover {
filter: brightness(0.85);
}
```
In the above code block, we see a component "Button" being cast as an anchor tag from the Styled Components library. This special anchor tag and its underlying style declarations are what gets rendered wherever the `</Button>` component is declared. However, what we don't see happening under the hood is that this component also has a unique class name assigned to it to enhance its specificity; in a situation where we create this exact component elsewhere, that new copy that is created will have its own unique class name created by Styled Components thus making every component we create unique. It is particularly difficult to have clashes using this approach.
The drawbacks to this method include:
- It could be slow and tedious to write.
- There is plenty of boilerplate code involved, making your project more bulky than necessary
- It is not as performant as Tailwind
In conclusion, there is no one-size-fits-all solution to writing CSS, there isn't a silver bullet either. These are my go-to approaches to solving most styling needs across all the projects I've worked on. I hope I've provided enough information for you to make a choice you like.
Cheers!
(PS: Stick around if you want to hear about why I love React and the HNG internship I'm currently enrolled in :) )
## PS
I've been writing React for about 2 years now and it is undoubtedly my favorite front-end library. A lot of factors come into place to make this so; there is a large, wholesome community of developers ready to help on forums and social media; the documentation is amazing and helps you understand it quickly and easily; last, but not least, it is the choice front-end technology at HNG. This makes things easier for me as it is right within my wheelhouse and I can get straight into building things with great engineers.

1,905,558 | Supervised Learning | Imagine you're learning to play a musical instrument. In the beginning, you need constant guidance... | 0 | 2024-06-29T11:21:26 | https://dev.to/moubarakmohame4/supervised-learning-31pb | machinelearning, ai, beginners, datascience | Imagine you're learning to play a musical instrument. In the beginning, you need constant guidance from your teacher: which note to play, how to position your fingers, what rhythm to follow. Each time you play an incorrect note, your teacher corrects you, guides you, and shows you the right way to do it. Over time, with enough practice and corrections, you become more and more skilled, capable of playing increasingly complex pieces. This is exactly what supervised learning does in the world of artificial intelligence. It's a process where an algorithm is guided and corrected at each step using pre-labeled examples. Each input is paired with the expected output, much like the advice from your music teacher. The algorithm compares its results to the expected outcomes and adjusts its model accordingly, gradually learning to perform tasks with increasing accuracy.
The main tasks involved in supervised learning are classification, regression, and prediction.
**1. Classification**
In the task of classification, the expected output is a category, such as "sick" or "healthy" in the medical field. This is one of the most common tasks, which is why many algorithms are available for it. The learning algorithm receives numerous examples belonging to all the categories to be predicted. Models often associate a probability, known as "confidence," with their predictions, such as "sick" at 0.27 (or 27%) and "healthy" at 0.73 (or 73%).
This probability helps refine the subsequent decisions based on a threshold: only values exceeding the set threshold are considered. By adjusting this threshold, it is possible, to some extent, to influence the rates of false positives or false negatives depending on the desired application. If there are two classes, it is called binary classification; otherwise, it is called multiclass classification. Even though the most complex cases sometimes involve thousands of classes, most practical cases require fewer than twenty classes.
**2. Classification: The Case of Images**
In the case of images, the "classic" task of classification can be refined into three distinct tasks, ordered by complexity:
**- Labeling: **This involves associating one or more labels with each image based on its content, often with a confidence score. A specific example is facial recognition, where the task is to identify individuals based on their faces.
**- Detection: **This involves indicating where in the image certain objects are located using bounding boxes. Mobile applications like Snapchat often use this to determine the location of a face in order to place elements accordingly, such as glasses on the eyes, cat ears on the head, or a cat nose on the nose.
**- Segmentation: **This involves indicating which pixel belongs to which object in the image. For example, this task is used by Kinect, the "intelligent" camera for Xbox (Microsoft), to determine the position of each part of the player's body in the image.
In the first case, the entire image is classified. In the second, the corresponding area of the image is indicated via pairs of coordinates. In the third, it amounts to applying a classification to each pixel in the image.For video, the problem becomes even more complex by adding a temporal dimension. For example, the action of writing is differentiated from the action of holding a pen by the movement of the pen on the paper over time.
**3. Regression**
In the task of regression, the expected output is a numerical value based on features. This differs from classification, where the output is a category from a fixed list, as here it involves predicting a real number within a specified range. This allows for predictions such as the price of a product or service, or the annual electricity consumption of a household.
However, it's important to note: while the expected results for most applications fall within two fixed bounds, the model itself typically does not enforce these limits. Post-processing of the model's results is often required to ensure they meet specific constraints. For example, in predicting the price of a product, it's necessary to verify afterward that the model's output is indeed positive. Yet, it's not feasible to directly impose this constraint on the model, which could potentially output negative.
**4. Forecasting**
The task of forecasting is a specific type of regression. Instead of using features to determine a numerical value, the goal is to predict the output based on previous values of the same variable. For example, to predict the price of a product, rather than focusing on its intrinsic characteristics (such as size, material, capabilities, etc.), the next price would be inferred from its price evolution in the past.

Weaknesses:
Smaller Ecosystem: Compared to React, Svelte has a smaller community and fewer third-party libraries.
Learning Curve: While simple, Svelte introduces some unique concepts that may take time to master.
SolidJS: Reactive and Declarative
Overview:
SolidJS, created by Ryan Carniato, is a declarative JavaScript library for building user interfaces. SolidJS focuses on fine-grained reactivity, drawing inspiration from React but with a different approach to reactivity and rendering.
Key Features:
Fine-Grained Reactivity: SolidJS uses fine-grained reactive primitives to track state changes precisely, leading to highly optimized updates.
JSX Syntax: Like React, SolidJS uses JSX for templating, making it familiar for React developers.
No Virtual DOM: Similar to Svelte, SolidJS avoids the Virtual DOM, ensuring direct updates to the DOM.
Strengths:
Performance: SolidJS’s fine-grained reactivity ensures efficient updates, making it one of the fastest frameworks available.
React Compatibility: The use of JSX and a similar component model make it easier for React developers to transition to SolidJS.
Weaknesses:
Smaller Ecosystem: Like Svelte, SolidJS has a smaller community and ecosystem compared to React.
Complexity: Fine-grained reactivity can be complex to understand and manage, especially for beginners.
ReactJS at HNG: Expectations and Excitement
At HNG, ReactJS is a cornerstone of the development stack. As an intern, I look forward to leveraging React’s powerful features to build dynamic and responsive user interfaces. React’s component-based architecture and extensive ecosystem make it an excellent choice for large-scale applications.

As a beginner, always start with the basics - HTML, CSS, and JavaScript before moving on to more advanced frameworks and tools. Going further, we will be looking at the differences between Javascript and Typescript.
**Javascript vs Typescript: A beginner's guide**
JavaScript (JS) and TypeScript (TS) are both essential technologies for frontend development. Understanding their similarities and differences is crucial for building robust, interactive, and visually appealing web applications and sites.
**What is Javascript?**
*JavaScript* is a programming language that is widely used for web development to create interactive elements within web browsers. It is used to manipulate the DOM, handle events, create animations, and make asynchronous requests (AJAX) to servers. JavaScript is dynamically typed; meaning variable types are determined at runtime, which offers great flexibility but can lead to errors that are hard to debug. For example:
```Javascript
let message = "Hello, world!";
console.log(message);
```
Advantages:
- **Pervasive/Ubiquity**: Javascript is supported by all modern web browsers. It can be used on all modern web browsers.
- **Community**: Javascript has a large community with plenty of libraries and frameworks (like React, Angular, Vue).
- **Versatile**: Javascript can be used for both client-side and server-side (Node.js) programming.
Disadvantages:
- **Error-Prone**: Javascript is dynamically typed. Dynamic typing can lead to runtime errors.
- **Complexity**: As projects grow, maintaining JavaScript code can become complex without proper structure and discipline.
###**What is Typescript?**
*TypeScript* is a superset of JavaScript that adds static typing and other features to the language. It is designed to develop large applications and transcompiles to JavaScript. TypeScript introduces static types, which allows developers to catch errors at compile-time rather than runtime. For example:
```Typescript
let message: string = "Hello, world!";
console.log(message);
```
Advantages:
- **Type Safety**: Catches type-related errors during development, reducing runtime errors.
- **Readability**: Improves code readability and maintainability with type annotations.
- **Tooling**: Better support for modern IDEs with autocompletion, refactoring, and navigation.
Disadvantages:
- **Learning Curve**: Requires learning new concepts if you're coming from JavaScript.
- **Compilation**: Needs to be compiled to JavaScript, adding an extra build step.
**What are the differences between Javascript and Typescript**
**Typing**
*JavaScript* is dynamically typed which means that the data type of a variable is determined during runtime. This flexibility can sometimes lead to unexpected errors. Conversely, *TypeScript* is statically typed which ensures that the data type of a variable is determined at compile time, making TypeScript codes safer and less prone to errors. TypeScript sometimes requires explicit type definitions or uses type inference.
```Javascript
let count = "5"; // Javascript-this code is expects a number as a value, but a string is passed, but Javascript has no issues with it because it is a valid code.
```
```Typescript
let count: number = "5"; // TypeScript-will throw an error because the type is number.
```
**Error checking and handling**
*JavaScript*, as a dynamically typed language, only detects errors at runtime, which can lead to runtime failures that are harder to debug. *TypeScript*, being a statically typed language, catches errors during the compile time, making it easier to identify and fix issues early in the development cycle.
**Compilation**
*JavaScript* code is executed directly by web browsers or Node.js without the need for prior compilation. In contrast, *TypeScript* code must be compiled into JavaScript before it can be executed, which adds an extra step in the development process while enhancing code reliability and error checking.
**Tooling**
*JavaScript*, while powerful, does not inherently provide all the necessary tooling for modern development, as it has evolved developers have created list of tools to improve the development process. *TypeScript* offers enhanced tooling capabilities such as autocompletion, better tooling, type checking and safety, improved code and more.
**Development Experience**
*JavaScript* is faster to write due to less strict rules, and is suitable for quick prototyping. *TypeScript* on the other hand, may take more time upfront but it results in more robust and maintainable code, especially for large-scale applications.
**Use cases**
*JavaScript* is good for quick Prototyping, like when you need to quickly test ideas and build small applications. It is well-suited for small to medium-sized projects due to its simplicity and flexibility. *Typescript* on the other hand is used for large projects. It is used when working on large codebases where maintainability and readability are key. It is also also used for team projects or in teams, to ensure consistent code quality and prevent type-related bugs. Many modern frameworks like Angular use TypeScript, and using it can enhance the development experience.
**My Journey with HNG…**
At HNG, React is the Framework(frontend technology)used extensively, React is a Javascript framework that is used to build fast and interactive user interfaces, it is also efficient and flexible. The ability to integrate React with other technologies and frameworks means that it can adapt to a wide range of things, from simple web applications to complex applications. It was first developed by Facebook in 2011.
**What is HNG?**
HNG is a global internship program that focuses on training young individuals in software development. Participants are given real-world projects to work on and are mentored by industry professionals.
**How does the HNG Internship program works?**
It is my first experience with HNG and i am exhilarated because i will be challenging myself , so it is both exhilarating and daunting opportunity at the same time. I am also a bit new to React but i have built a couple of things with it. I am looking forward to contributing in no little way to the growth of HNG using the little knowledge i have of React, while also improving on my React skills. I expect to become a part of a team, contribute actively on that team, collaborate with others, build upon my existing knowledge and skills, among other things. Back to how the HNG internship works, To relive your curiosity visit [HNG Internship](https://medium.com/r/?url=https%3A%2F%2Fhng.tech%2Finternship) and [HNG Hire](https://medium.com/r/?url=https%3A%2F%2Fhng.tech%2Fhire) for more information.
**Conclusion**
In conclusion, most times we are plagued with making a choice, picking between one thing or the other. For instance, picking between Angular or Vue, Visual Studio code or Sublime text, Javascript or Typescript. I hope what i am about to say next answers one of your questions, both JavaScript and TypeScript have their place in web development. JavaScript is great for its simplicity and flexible nature, making it ideal for small projects and quick prototyping.- While TypeScript with its static typing and enhanced tooling, is better suited for larger, complex projects and team environments. As a beginner, starting with JavaScript provides a solid foundation, and learning TypeScript can be a natural progression to writing more reliable and maintainable code. *Does this answer your question?* *Will you play around with both Javascript and Typescript?*

```
ease(t, tMin, tMax, value1, value2)
```
ECAbrams has a great tutorial on it [here](https://www.youtube.com/watch?v=OTivs6mMzpU). In short, you can use the ease expression to remap values, like time, in order to create movement. As the name suggests, the expression eases from "value1" to "value2", between "tMin" and "tMax". So if you typed this into your position parameter:
```
x = ease(time, 0, 2, 500, 700);
[x, value[1]]
```
Your x co-ordinate will animate from 500 to 700, between 0-2 seconds on your timeline, easing in and out.
But sometimes the default ease isn't what I'm looking for, and unlike keyframes, we can't just play around in the graph editor when it comes to expressions. Which means a lot of math in order to make the easing more unique. Fortunately, we have [Penner's easing functions](http://robertpenner.com/easing/). The link is a great resource by Robert Penner, who has done all the heavy lifting to make some really varied easing options. The link provides many options for using the functions in various code languages.
If, like me, you want to look at the code and tweak it for your needs in After Effects, then you probably want to head over to the [Javascript link](https://github.com/danro/jquery-easing/blob/master/jquery.easing.js). Here you'll see the functions layed out clearly. From there, you can almost copy/paste straight into After Effects, but you'll need to make some slight format changes. For instance, the code written on GitHub is like this:
```
easeInQuad: function (x, t, b, c, d) {
return c(t/=d)t + b;
}
```
But in order to make it work in After Effects, you need to swap the position of "function" and the function name. I also went ahead and removed "x" as it's not necessary when applied to a parameter in After Effects. So when you're done the altered code looks like this:
```
function easeInQuad(t, b, c, d) {
return c(t/=d)t + b;
}
```
As explained on the website, t = current time, b = beginning value, c = change in value, and d = duration.
Going a step further, I wanted to create my own .jsx file to store all the easing functions, so I didn't have to type them out over and over for different projects. I did this with a little help from using [Motion Developer's tools](https://motiondeveloper.com/). By looking at how they created their aeFunctions jsx file, I was able to make my own callable functions in After Effects, by typing the following into ExtendScript Toolkit CC:
```
{
getFunctions(time = thisLayer.time) {
//Inset function code here
}
return {
//Insert name of functions on each line separated by commas:
//function1,
//function2,
//etc,
};
},
}
```
Once the file is created, you can import it into your project. Then, should you wish to use one of your saved functions, you simply need to pull the data from the jsx file. You can do so by starting off your expression code in your chosen parameter with this:
```
const {ref name} = footage("file.jsx").sourceData.getFunctions();
```
where {ref name} is whatever your prefered label is (I usually go with "penner"), and "file.jsx" is the file with your functions saved. The file doesn't need to be in your timeline for this to work, as the expression is drawing from the project panel, but putting the jsx file in your timeline and shy guy-ing away can prevent it from being accidently deleted if your collect the project later.
Then when you want to use a function, you can do so like this:
```
{ref name}.{name of function}();
```
Motion developer also explain how it works (and links to their free collection of functions) [here](https://motiondeveloper.com/tools/aefunctions).
And that's it! Nicer easing for your after effects expression-driven animations.
The only thing to note is Penner's functions work slightly differently to the default ease, which asks you to imput 4 arguements (tMin, tMax, value1, value2). Penner's easing only asks for 3 (beginning value, change in value, duration). So bear this is mind when imputting your values.
Please check out Motion Developer and Robert Penner's resources, and show them support if their work is helpful to you.

In frontend development, two technologies have gained attention for their performance and efficiency: Svelte and Astro. Both frameworks prioritize speed and minimalism, but they differ in their approaches. In this article, we'll delve into the differences between Astro and Svelte, and explore what makes them suitable for specific use cases.
Svelte:
Svelte is a well-established framework that compiles code at build time, resulting in smaller bundle sizes and faster performance. Svelte uses a virtual DOM, but it's more lightweight and efficient than other frameworks. Its component-based architecture and store management make it an attractive choice for building complex applications.
Astro:
Astro, on the other hand, is a relatively new frontend framework that utilizes a unique approach called "Island Architecture."
It allows developers to build applications as a collection of smaller, independent components, resulting in faster page loads and improved performance. Astro also leverages native web technologies like HTML, CSS, and JavaScript, making it a lightweight and flexible option.
Comparison:
Astro and Svelte share similarities in their focus on performance and minimalism, but they differ in their approaches. Astro's Island Architecture provides a more modular and flexible way of building applications, while Svelte's compilation process offers better optimization and bundling. Astro is ideal for smaller applications or those requiring extreme performance optimization, while Svelte is better suited for complex applications with a need for extensive component libraries.
In Conclusion:
Astro and Svelte are both lightweight frontend technologies that prioritize performance and efficiency. By understanding their differences, developers can choose the best tool for their project's needs. Whether you're building a high-performance application with Astro or a complex enterprise app with Svelte, the right technology can make all the difference.

I have been using mysql for quite some time.
It was hard at first but then it became simple to understand.
Then I had to work with Mongodb which was not so thrilling for me.
It was hard making a switch.
Mysql excelled at relational data and joining tables, Mongodb has its ways of connecting multiple documents but that became a problem for me because it was not as straightforward as mysql.
It made retrieving complex data a pain.
Mongodb is a powerful tool but it's a bit complex and you need to learn all about that.
If you are comfortable with mysql just like I was, transitioning to mongodb requires a significant investment in time, effort and patience.
Just be prepared for a new mindset and lots of learning!!!

### Step 1: Installation and Setup
First things first—let's get Adobe Premiere Pro installed on your computer. Head to Adobe's official website, download the Creative Cloud application, and from there, install Adobe Premiere Pro. Once installed, launch the software and let's commence our creative journey!
### Step 2: Understanding the Interface
Adobe Premiere Pro might feel a bit overwhelming at first glance, but fear not! The interface is designed to maximize efficiency once you understand the layout. The primary areas to focus on are:
- **Project Panel**: This is where all your media assets are stored.
- **Source Monitor**: For viewing and trimming raw media clips.
- **Timeline Panel**: The heart of your project, where you arrange and edit clips.
- **Program Monitor**: Displays the final edit, as represented on the Timeline.
Take a few minutes to explore and familiarize yourself with these panels—they are your best friends in the editing process!
## Loading and Organizing Media
### Step 3: Importing Media Assets
To begin your project, you need to import your media files. Simply go to the **File** menu and select **Import**, or use the shortcut `Cmd + I` (Mac) or `Ctrl + I` (Windows). Choose the files you need, and they will appear in the Project Panel.
### Step 4: Organizing Your Media
A well-organized Project Panel can save you a lot of time. Create bins (folders) to sort your media into categories such as video clips, audio files, images, and graphics. You can create a new bin by right-clicking in the Project Panel and selecting **New Bin**.
## Basic Editing Techniques
### Step 5: Creating a Sequence
Sequences are where you assemble and edit your media. To create a new sequence, right-click in the Project Panel, select **New Item**, and then **Sequence**. You can choose from various presets or customize settings to match your media.
### Step 6: Adding Clips to the Timeline
Drag your clips from the Project Panel to the Timeline. Arrange them in the order you want, and use the Razor Tool (`C` key) to make cuts. To delete a portion, simply select it and press `Delete`.
### Step 7: Trimming and Adjusting Clips
Adjust the length of clips by dragging the edges in the Timeline. For precision trimming, use the **Ripple Edit Tool** (`B` key). This tool allows you to shorten or lengthen clips without creating gaps.
## Enhancing Your Video
### Step 8: Adding Transitions
Smooth transitions are the key to professional-looking videos. Go to the **Effects Panel** and search for **Video Transitions**. Drag your desired transition effect (like cross dissolve or dip to black) to the beginning or end of your clips in the Timeline.
### Step 9: Working with Audio
Good audio quality is just as important as clear visuals. Import your audio tracks and place them on the Timeline. To adjust volume levels, use the **Audio Mixer** Panel, and for more precise control, keyframe volume changes directly in the Timeline.
### Step 10: Applying Effects and Color Correction
To make your video visually appealing, apply color correction and effects. Navigate to the **Lumetri Color Panel** for adjustments like exposure, contrast, highlights, and shadows. Experiment with different looks until you find what fits your project best.
## Exporting Your Final Video
### Step 11: Rendering and Exporting
Once your project is edited to perfection, it’s time to export! Go to **File > Export > Media**. The **Export Settings** menu will appear. Select the format and preset that best suits your needs—H.264 is a great option for most online platforms. Click **Export** and let Premiere Pro do its magic.
## Conclusion
And there you have it—a comprehensive guide to getting started with Adobe Premiere Pro! From setting up and importing media to adding final touches and exporting your masterpiece, these steps will help you produce professional-looking videos that capture attention.
Happy editing, and remember—the only limit is your imagination! 🎬✨ | quantumcybersolution |

1,905,530 | MY JOURNEY IN HNG AS I NAVIGATE THE USE OF MOBILE DEVELOPMENT PLATFORMS | In the dynamic world of mobile development, selecting the right platform and software architecture... | 0 | 2024-06-29T10:51:22 | https://dev.to/obafemi_damilola_c628cdc1/my-journey-in-hng-as-i-navigate-the-use-of-mobile-development-platforms-4k1d | javascript, mobile, reactnative, flutter | In the dynamic world of mobile development, selecting the right platform and software architecture pattern is essential for the success of any mobile application. Each platform and pattern has its strengths and weaknesses, making them suitable for different project requirements
In this article, we are exploring the key mobile development platforms and the common software architecture patterns used in the industry, highlighting their pros and cons.
## Mobile Development Platforms
iOS and Android are the two dominant platforms in the mobile development world.
**iOS**, known for its high performance, robust security, and lucrative user base, is confined to Apple devices alone and requires proficiency in Swift and Objective-C. This restriction can be a limitation, but the rewards are significant for those who master the platform.
On the other hand, **Android** offers open-source flexibility and extensive device compatibility, attracting a vast user base. However, the fragmentation across different devices can pose challenges in ensuring consistent user experiences.
Cross-platform development frameworks like _React Native_ and _Flutter_ have gained popularity due to their ability to reuse code across iOS and Android, thus reducing development time and costs. These frameworks facilitate rapid time-to-market and broader market reach, making them attractive to many developers. Nevertheless, potential performance issues and limited access to native device features remain notable drawbacks.
## Common Software Architecture Patterns
- MVC (Model-View-Controller)
It is a foundational pattern in mobile app architecture that initiates the separation of concerns thereby separating the application into three interconnected components making the easy to maintain and test. However, it can lead to complex codebase management as the app grows.
- MVP (Model-View-Presenter)
It enhances MVC by bettering the separation of UI which reduces the burden on the view, making it more manageable and testable. However, the introduction of additional layers and more boilerplate code makes it complex.
- MVVM (Model-View-ViewModel)
It facilitates unit testing and also separation of concerns which particularly enhances data binding in UI development. However, the steep learning curve, can be an overkill for simple apps.
I'm a Frontend Developer looking to strengthen my hands on mobile development. And guess what, that's where HNG comes into play.
As I embark on my journey with the HNG Internship, I am eager to deepen my practical understanding of these platforms and patterns. Working on diverse and challenging tasks will help me learn and sharpen my skills to gain hands-on experience. My involvement in this internship is a stepping stone because of it's structured learning environment and the mentorship provided making it instrumental in shaping my career as a proficient mobile developer.

1,905,526 | Nextjs custom server with fastify | React server-side rendering support for Fastify with Next.js framework In this post we will create... | 0 | 2024-06-29T10:49:23 | https://dev.to/markuz899/nextjs-custom-server-with-fastify-4gfe | react, nextjs, fastify, javascript | 
**React server-side rendering support for Fastify with Next.js framework**
In this post we will create a custom server to start an app in nextjs with fastify underneath.
Let's create a new app in nextjs with npx
```
npx create-next-app@latest
```
Let's proceed with the installation of the dependencies
```
npm install fastify @fastify/static fastify-env dotenv
```
First let's create an .env file at the root
```
PORT=6100
```
On the root of the project, so to speak, next to the src folder we are going to create a new folder called **server**
Inside we create an index.js file
The content will look like this
```
require("dotenv").config();
const fastify = require("fastify")();
const fastifyStatic = require("@fastify/static");
const path = require("path");
const next = require("next");
const dev = process.env.NODE_ENV !== "production";
const host = process.env.HOST || "localhost";
const port = parseInt(process.env.PORT || "6100");
const app = next({ dev });
const handle = app.getRequestHandler();
(async () => {
try {
await app.prepare();
fastify.register(fastifyStatic, {
root: path.join(__dirname, "..", "public", "static"),
prefix: "/static/",
});
fastify.all("/*", (req, reply) => {
reply.hijack();
handle(req.raw, reply.raw)
.then(() => {
reply.raw.end();
})
.catch((err) => {
fastify.log.error(err);
reply.raw.writeHead(500);
reply.raw.end("Internal Server Error");
});
});
await fastify.listen({ port, host });
console.log(`Fastify server ready on port: ${port}`);
} catch (err) {
console.log(err);
process.exit(1);
}
})();
```
This is the package.json file with the related run and build scripts
```
{
"name": "nextjs_fastify",
"version": "0.1.0",
"private": true,
"scripts": {
"dev-next": "next dev",
"dev": "node server/index.js",
"prod": "cross-env NODE_ENV=production node ./server/index.js",
"build": "next build",
"start": "next start",
"lint": "next lint"
},
"dependencies": {
"@fastify/static": "^7.0.4",
"dotenv": "^16.4.5",
"fastify": "^4.28.1",
"fastify-env": "^2.2.0",
"next": "^14.2.4",
"react": "^18",
"react-dom": "^18"
},
"devDependencies": {
"@types/next": "^9.0.0",
"@types/node": "^20.14.9",
"@types/react": "^18",
"@types/react-dom": "^18",
"cross-env": "^7.0.3",
"typescript": "^5"
}
}
```
Now all we have to do is run the desired scripts and that's it
To run the server in dev mode
`npm run dev`
To run the server in production mode you will first need to create the build version
`npm run build`
Only after the build has been completed can we launch the server in production mode with
`npm run prod`
And tadaan we will now have a client in nextjs with fastify under the hood 🚀

1,905,528 | A COMPARISON BETWEEN SVELTE AND REACT, TWO FRONTEND TECHNOLOGY MARVELS | WHAT IS SVELTE? Svelte is an open-source front-end JavaScript framework developed by Rich Harris. He... | 0 | 2024-06-29T10:48:27 | https://dev.to/scofieldominic/a-comparison-between-svelte-and-react-two-frontend-technology-marvels-5bc8 | react, svelte, javascript | WHAT IS SVELTE?
Svelte is an open-source front-end JavaScript framework developed by Rich Harris. He designed it for building UI’s for web applications. Its first version was released in the year 2016.
Svelte was developed as a more efficient and user-friendly version of React.js and Vue.js.
WHAT IS REACT?
React is an open-source JavaScript library for designing user interfaces (UI's). It was developed in Facebook, now Meta by Jordan Walke, a software engineer.
Its first version was released in the year 2013.
React is based on a component-based model, this is done by dividing a complete React application into smaller but singular applications.
SIMILARITIES BETWEEN SVELTE AND REACT
1. They are both based on JavaScript and designed for the modification of UI.
2. They both use component-based architecture.
3. They both are open-source front-end JavaScript technologies with substantial communities of users.
4. They both have an automatic UI data update.
5. They have similar syntax which is based on JSX.
DIFFERENCES BETWEEN SVELTE AND REACT
BEGINNER FRIENDLY: Svelte sticks closely to JavaScript’s classic web development models, and introduces only a few extensions to HTML, making it much easier to learn While React Can be daunting and needs a good knowledge of JSX and CSS-in-JS to build even the most basic applications.
EFFICIENCY: Svelte Uses a compiler that processes codes at a faster speed while React uses Virtual DOM (Document Object Model) which is slower in code processing.
USER EXPERIENCE: Svelte requires lesser lines of code to develop a simple application compared to React.
TECHNOLOGY: Svelte is a UI Framework while React is a UI library.
SIZE: Svelte has a bigger size due to its built-in compiler compared to React that uses a virtual DOM which requires less.
TOOLS: Svelte has less available dev tools while React has a lot dev tools available to it.
THIRD PARTY SUPPORT: Requires little third-party support as most of its components are inbuilt while React requires a lot of third-party support as it sources data externally.
COMMUNITY: Svelte has a growing community of users but compared to React which has a huge community support, it has a long way to go.
HOW TO MAKE A CHOICE BETWEEN SVELTE AND REACT
Svelte excels over React in the following cases;
1. Learning web development: user friendly and simpler syntax.
2. Complex Data Visualization: compatible with various tools which makes data visualization simpler.
3. Realtime applications and dashboards: Because of its efficiency, its better for applications that require real time data updates.
Reacts excels over Svelte in the following cases;
1. Highly dynamic UI’s: Makes the management of complex applications easier due to its component-based model.
2. Mobile applications: Offers a framework for designing and developing mobile applications.
3. Rendering: React with the aid of powerful tools like Next.js is excellent for developing applications that require robust rendering.
4. Reusable design: Excels in the development and maintenance of reusable UI components.
CONCLUSION:
Choosing between Svelte and React is dependent on multiple factors such as project type, JavaScript knowledge and experience, scope and complexity of your project, and your personal preference.
Both React and Svelte have their advantages and disadvantages. Svelte is known for its smaller code footprint, better efficiency, and lesser development time due to its simple syntax while React has a component-based architecture that makes handling a more extensive range of complex web projects easier.
It’s important you put into considerations the trade-offs of each technology before commencing on a project

1,905,527 | Basic Differences Between SSR and SSG | In the modern web development world, performance and user experience are everything. While developers... | 0 | 2024-06-29T10:46:03 | https://dev.to/sheraz4194/basic-differences-between-ssr-and-ssg-1ing | ssr, ssg, nextjs, react | In the modern web development world, performance and user experience are everything. While developers pursue optimization of the apps, it is very important to know about variety in rendering techniques In this post, we are going to discuss the **Next.js** framework and its features like Server-Side Rendering (SSR) & Static Site Generation (SSG).. We will look at what this other is, why they are good, and when to use each of them.
## What is Server-Side Rendering (SSR)?
Server Side Rendering (SSR) is a technique to render HTML of the page from Server on each request A user requests a page, the server gets some information to place in that page and creates HTML which is then sent over to the client's browser. The browser actually renders the HTML and then shows this fully rendered page to user.
## How Server Side Rendering (SSR) Works
1. Request: A user makes a request to the server.
2. Data Fetching: The server fetches the necessary data to render the page.
3. HTML Generation: The server generates the HTML using the fetched data.
4. Response: The server sends the generated HTML to the client's browser.
5. Rendering: The browser renders the HTML and displays the page to the user
## Advantages of Server Side Rendering:
- SEO-Friendly: Since the HTML is generated on the server and sent to the client, search engines can easily crawl and index the content, improving SEO.
- Faster Initial Load: Users receive a fully rendered page on their first request, leading to faster initial load times.
- Dynamic Content: Ideal for pages that require real-time data fetching or frequently updated content.
## What is Static Site Generation (SSG)?
In static site generation, HTML pages are generated at build time. In Static Site Generation HTML is generated just once and server pre-renders HTML pages to users.
## How SSG Works
1. Build Time: During the build process, the server fetches the necessary data and generates static HTML pages.
2. Request: A user makes a request to the server.
3. Response: The server serves the pre-rendered static HTML page to the client's browser.
4. Rendering: The browser renders the HTML and displays the page to the user.
## Benefits of SSG
- Blazing Fast Load Times: Since the HTML is pre-rendered and served as static files, SSG pages load extremely quickly.
- Scalability: Serving static files is a turbo process and can handle high traffic with ease.
- Improved Security: With no server-side code execution on each request, there are fewer attack vectors, improving security.
- When to Use SSR
- Dynamic Content: Use SSR for pages that require real-time data fetching or frequently updated content. For examples news websites, e-commerce platforms with constantly changing inventory, and user dashboards.
- SEO Optimization: When SEO is a priority, SSR ensures that search engines can crawl and index the content effectively.
- Personalized Content: Pages that deliver personalized content based on user data or preferences benefit from SSR, as the server can tailor the HTML to each user.
- When to Use SSG
- Static Content: Use SSG for pages with static or rarely changing content. Blogs, documentation sites, marketing pages, and portfolios are great examples for SSG.
- Performance-Critical Applications: For applications where performance is crucial, SSG's pre-rendered pages offer blazing fast load times. So use it when you need turbo performance.
- Cost Efficiency: Serving static files is cost-effective, making SSG an excellent choice for projects with budget constraints.
## Combining SSR and SSG in Next.js
But Hang on, wouldn't it be great if we use both? One of the standout features of Next.js is its ability to seamlessly combine SSR and SSG within the same application. You can choose the rendering method that best suits each page's requirements, optimizing performance and user experience across your entire site. In short you can decide which page should render with SSG and which should render with SSR. Blessings of Nextjs not even stop here. You can even chose even which component on the page should render with SSR and which should render on SSG.
To combine SSR and SSG, we just need to add `use client` for rendering a page on client-side. By default all Nextjs components render on server. Below I will be creating an admin dashboard page, one component of the page render on client-side [SSG] and one will render on server0side [SSR].
This is a sever component by default:
```
// app/page.tsx
import AdminStats from '/components/admin-stats';
import AdminProductsCount from '/components/admin-products0count'
export default function AdminDashboard (){
return (
<main className="flex flex-col gap-2">
<AdminStats/>
<AdminProductCount/>
</main>
);
}
```
Admin Stats goes here:
```
export default async function AdminStats(){
const stats = await fetch('/https://api.example.com/stats');
return (
<div>
<p>{admin.total_views}</p>
<p>{admin.total_sales}</p>
</div>
);
}
```
And admin products count. We just add `use client` directive and the component become a client component
```
'use client'
import { useState } from 'react';
export default function AdminProductCounts(){
const [products,setProducts] = useState<number | null>(null)
return (
<div>
{products ? <p>{products}<p>:<p>You don't have any products yet</p>
</div>
)
}
```
## What I prefer?
My personal preference is rendering components on the server side (SSR) for several important reasons. First of all, SSR improves SEO by providing fully rendered HTML to search engines, ensuring better indexing and visibility. Secondly, it enhances the initial load time, as users receive a pre-rendered page directly from the server, leading to a smoother and faster user experience. Thirdly, SSR allows for better management of dynamic content, ensuring that users always see the most up-to-date information without requiring additional client-side processing. Finally, it improves security by minimizing the exposure of sensitive logic and data to the client-side, reducing potential attack vectors.
## Conclusion
Understanding when to use SSR and SSG is much important for building turbo-performance, scalable React or Next applications. SSR excels in scenarios requiring dynamic content, real-time data, and SEO optimization, while SSG shines in performance-critical applications with static or rarely changing content. By leveraging Next.js's flexibility to combine SSR and SSG, you can optimize your application's performance and user experience, delivering the best of both worlds.
Give SSR and SSG a try in your next project and experience the benefits of efficient and flexible rendering methods!

1,905,511 | Solving a Booking System Issue on a Photography Website: My Journey in the HNG Internship. | It is an exciting moment for me as a software developer to start the HNG Internship journey. The... | 0 | 2024-06-29T10:42:01 | https://dev.to/solomonxuche/solving-a-booking-system-issue-on-a-photography-website-my-journey-in-the-hng-internship-1g0m | webdev, backend, django, python | It is an exciting moment for me as a software developer to start the HNG Internship journey. The program is promises to provide me with practical experience, hone my abilities, and establish connections with other professionals who share my interests. I want to discuss a recent difficult backend issue I ran across and how I resolved it before I go any farther on this adventure.
## The Challenge
My assignment was to put in place a booking system for a photography website. One significant issue in the original system was that it did not take session duration into consideration, which meant that multiple clients may book the same date and time, resulting in scheduling conflicts.
## My Step-by-Step Solution
**Step 1: Understanding the Problem**
The first step was to understand the cause of the booking conflicts. The system allowed multiple clients to book the same date and time without considering the session duration, I also observed the database structure lacked fields to manage start and end times for each session.
**Step 2: Redesigning the Database**
To address this, I restructured the database to include new fields like `start_time` and `end_time.` This allowed the system to keep track of when each session started and ended.
**Step 3: Calculating Session Duration**
I then implemented logic to automatically calculate the duration of each session based on the start and end times. This ensured that no two sessions overlapped.
**Step 4: Fixing the Conflicting/Overlapping Bookings**
To prevent conflicting or overlapping bookings, I added validation checks in the booking process. If a user tried to book a session that overlapped with an existing one, the system would prompt an error message and suggest available times.
**Step 5: User Notification**
Additionally, I set up a notification system to inform users when their booking was confirmed or if there was a conflict. Users would receive an error message on the website and an email notification if their preferred time slot was unavailable.
## Conclusion
Solving backend problems is part of the exciting journey of a software engineer. By breaking down the problem, analyzing it, and applying effective solutions, we can overcome challenges and improve system performance. The HNG Internship is a fantastic opportunity to further hone these skills, and I am very happy to be a part of it.
I look forward to the experiences and knowledge this internship will bring, and I am ready to tackle more challenges head-on.

### Histogram Awareness
Keep an eye on the histogram at the top. It shows the tonal range of your photo and helps prevent clipping in highlights and shadows.
## Advanced Editing Tips
For those looking to enhance their images further:
- **Graduated Filter**: Apply effects gradually across a part of your photo.
- **Radial Filter**: Focus on a circular or elliptical area for localized adjustments.
- **Adjustment Brush**: Paint edits onto specific areas of your photo.

Once your photos look stellar, it's time to export them:
1. **Select Photos**: Choose the photos you want to export from the Library module.
2. **Export Dialog**: Click "Export" and a dialog box will appear.
3. **Set Parameters**: Define file naming, format, quality, and destination. You can also add watermarks if necessary.

1,905,519 | Asynchronous JavaScript: An In-Depth Guide | JavaScript is a versatile programming language that powers a vast majority of the web's interactive... | 0 | 2024-06-29T10:34:35 | https://dev.to/genius1k/asynchronous-javascript-an-in-depth-guide-oea | webdev, javascript, programming, tutorial | 
JavaScript is a versatile programming language that powers a vast majority of the web's interactive and dynamic features. One of its key strengths lies in its ability to handle asynchronous operations, which are crucial for creating responsive and performant web applications. In this article, we'll delve into the world of asynchronous JavaScript, exploring its concepts, techniques, and practical applications.
**Understanding Asynchronous JavaScrip**
In JavaScript, code execution is typically synchronous and single-threaded, meaning each operation must be completed before the next one begins. This approach can be limiting, especially when dealing with tasks that take time to complete, such as network requests, file reading, or timers. Asynchronous JavaScript allows these time-consuming operations to run concurrently without blocking the execution of subsequent code.
**The Event Loop**
At the heart of JavaScript's asynchronous capabilities is the event loop, a mechanism that manages the execution of code, collects and processes events, and executes queued sub-tasks. The event loop continuously checks the call stack (where functions are executed) and the task queue (where asynchronous tasks are placed) to determine what should be processed next.
**Callbacks**
Callbacks are the simplest way to handle asynchronous operations. A callback is a function passed as an argument to another function, which is executed once an asynchronous operation completes.
```
function fetchData(callback) {
setTimeout(() => {
const data = { name: "John", age: 30 };
callback(data);
}, 2000);
}
fetchData((data) => {
console.log(data); // { name: "John", age: 30 }
});
```
While callbacks are straightforward, they can lead to "callback hell" or "pyramid of doom," where nested callbacks become difficult to read and maintain.
**Promises**
Promises provide a more elegant way to handle asynchronous operations. A promise represents a value that may be available now, in the future, or never. Promises have three states: pending, fulfilled, and rejected.
```
function fetchData() {
return new Promise((resolve, reject) => {
setTimeout(() => {
const data = { name: "John", age: 30 };
resolve(data);
}, 2000);
});
}
fetchData()
.then((data) => {
console.log(data); // { name: "John", age: 30 }
})
.catch((error) => {
console.error(error);
});
```
Promises can be chained, making it easier to handle sequential asynchronous operations without the nesting associated with callbacks.
**Async/Await**
Async/await is a syntactic sugar built on top of promises, introduced in ES2017 (ECMAScript 2017). It allows you to write asynchronous code that looks and behaves like synchronous code, making it easier to read and understand.
```
async function fetchData() {
return new Promise((resolve) => {
setTimeout(() => {
const data = { name: "John", age: 30 };
resolve(data);
}, 2000);
});
}
async function getData() {
try {
const data = await fetchData();
console.log(data); // { name: "John", age: 30 }
} catch (error) {
console.error(error);
}
}
getData();
```
With async functions, you can use the await keyword to pause the execution of the function until the promise is resolved, making the code easier to follow.
**Practical Applications**
Asynchronous JavaScript is essential for various real-world applications:
**Fetching Data from APIs**
One of the most common use cases for asynchronous JavaScript is fetching data from APIs.
```
async function fetchUsers() {
try {
const response = await fetch("https://jsonplaceholder.typicode.com/users");
const users = await response.json();
console.log(users);
} catch (error) {
console.error("Error fetching users:", error);
}
}
fetchUsers();
```
**Handling User Interactions**
Asynchronous operations are also crucial for handling user interactions, such as form submissions or button clicks, without blocking the UI.
```
document.getElementById("submit").addEventListener("click", async () => {
try {
const response = await fetch("/submit", {
method: "POST",
body: JSON.stringify({ name: "John" }),
headers: { "Content-Type": "application/json" }
});
const result = await response.json();
console.log(result);
} catch (error) {
console.error("Error submitting form:", error);
}
});
```
**Real-Time Updates**
For real-time updates, such as chat applications or live notifications, asynchronous JavaScript is indispensable.
```
const socket = new WebSocket("wss://example.com/socket");
socket.onmessage = (event) => {
const message = JSON.parse(event.data);
console.log("New message:", message);
};
```
**Conclusion**
Asynchronous JavaScript is a powerful tool that enables developers to create responsive and efficient web applications. By understanding and utilizing callbacks, promises, and async/await, you can handle asynchronous operations with ease and avoid common pitfalls. Whether you're fetching data from an API, handling user interactions, or implementing real-time updates, mastering asynchronous JavaScript is essential for modern web development. | genius1k |

1,905,514 | Week 2: Mastering AWS IAM | I delved into AWS Identity and Access Management (IAM) and learned how to apply fine-grained... | 0 | 2024-06-29T10:25:27 | https://dev.to/clintt/week-2-mastering-aws-iam-4k0o | aws, iam | I delved into AWS Identity and Access Management (IAM) and learned how to apply fine-grained permissions to AWS services and resources. This knowledge enables precise specification of which entities can access particular services and resources. Additionally, I explored how IAM manages permissions for users and applications, ensuring adherence to the principle of least privilege.
**AWS IAM:** A web service that securely controls access to AWS resources, managing who is authenticated (signed in) and authorized (has permissions) to use them.
**IAM Users:** Entities created in AWS representing users or applications that interact with AWS.
**IAM User Groups:** Collections of IAM users sharing specific permissions.
**IAM Roles:** Short-term, temporary credentials that can be assumed by an identity.
Here's a breakdown of what I did:
1. Creating IAM Users: I created IAM users and attached permissions to grant them administrative privileges.
2. Managing IAM Groups: I set up IAM groups with necessary permissions and added IAM users to these groups.
3. Establishing IAM Roles: I created IAM roles, developed policies, and attached these policies to the roles.
4. Configuring Access Keys: I generated access keys and configured the AWS Command Line Interface (CLI) to enable programmatic access to AWS resources.
5. Enabling Multi-Factor Authentication (MFA): I enforced MFA for users to enhance security.
In summary, I acquired a comprehensive understanding of AWS IAM and its crucial role in securing AWS resources. Through creating IAM users, groups, and roles, I effectively applied fine-grained permissions to control access. Enforcing the principle of least privilege and implementing MFA further fortified security. This knowledge equips me to manage AWS permissions meticulously, ensuring robust security and efficient access management for users and applications. | clintt |
1,905,512 | Why do we use Front-end technologies like React, Vue, and Angular? | Before we dive into today's main discussion, let's ask ourselves one very important question. Why do... | 0 | 2024-06-29T10:25:23 | https://dev.to/ambitious_dude/why-do-we-use-front-end-technologies-like-react-vue-and-angular-2pmc | webdev, javascript, react | Before we dive into today's main discussion, let's ask ourselves one very important question.
**_Why do front-end frameworks like React, Vue, and Angular, actually exist in the first place?_**
**_Why not simply use Vanilla JavaScript to build our apps?_**
Well, let's answer that question right away in this article.
The rise of front-end frameworks came into existence when Vanilla Javascript was no longer reliable to build complex UI. Let’s establish the fact that building any front-end application is all about handling data and then displaying that data in a nice user interface. That's basically all a web application does if you think about it.
So, it receives data, changes it as the user uses the app, and always displays the current data on the screen.
This means that the primary responsibility of a single-page app, and indeed any application or website, is to ensure that the user interface accurately reflects the current state of the data. In other words, the UI should always display the most recent data.
Let’s use the Airbnb application as an instance;
If you look closely at the picture provided, you will see that there is so much data. As we know, all of this data needs to be kept in sync with the user interface and the other pieces of data because they're all interconnected.
For example, when we change the data about location or dates, the UI needs to show those new dates, and the list of apartments needs to be updated. The map also needs to show the location of the apartments. Therefore, when the apartments change, the map must also change.
Now, just as a side note, in a real-world app like when using **React**, we call each data piece a state.
So, based on the example I showed you, I would say that without a framework, it would be virtually impossible to keep this huge amount of data in sync with this super complex UI.
**But still, you might be wondering why. Why would it be so hard to build something
like this with Vanilla JavaScript?**
Well, it comes down to the following: first, when building a complex front end with vanilla JavaScript alone, you should be aware that it requires large amounts of direct DOM traversing and manipulation.
Like in this application here, when building it with Vanilla JS, you would have to code
Manually target the element, do class toggling, DOM traversing, and even manipulation of text and CSS styles, and this is guaranteed to be an absolute nightmare for the developer in a complex app like Airbnb because the code would be extremely complex and hard to understand, and we will probably end
up with a huge mess of what is usually called spaghetti code in the world of technology.
So, the rise of front-end frameworks like React, Angular, and Vue came into play. While there are different choices of front-end frameworks to use, there are still some slight differences and similarities between the front-end technologies, and that is what we will discuss in the next few paragraphs.
## React, Vue, and Angular have several differences and similarities:
### Brief Definition
* React is a library for building UI components built by Facebook. It uses a virtual DOM and emphasizes a functional programming style.
* Vue is a progressive framework that can scale from a library to a full framework built by Evan You. It offers a gentle learning curve and two-way data binding.
* Angular is a Full-fledged framework with extensive features. It uses a component-based architecture and TypeScript to provide out-of-the-box solutions. It was built by Google.
* Let’s talk about the languages used. For React, it is primarily JavaScript with JSX (JavaScript XML) for templating. Don’t worry if you aren’t familiar with all these terms; join the HNG internship, where they use React for their front-end projects.
Vue uses a template syntax similar to HTML and can also use JavaScript for rendering. Lastly, Angular is built with TypeScript, enhancing type safety and tooling support.
* Another difference is that React uses a one-way data binding system, which enhances predictability. Vue used two-way data binding, making it easier to work with forms. Lastly, Angular also uses two-way data binding through its template syntax, offering a declarative way to bind data
* If you are a newbie who wants to use the frameworks, I would say Vue is much easier to learn if you judge by the learning curve. It is much more good for beginners. Followed by React with a moderate learning curve, focusing on JavaScript knowledge and understanding of JSX. While Angular is not that easy, maybe due to its extensive features and use of TypeScript.
They all have quite some similarities, like the component-based architecture, the updating of the UI, support for Modern Features, and many more.
These frameworks offer powerful tools for building modern web applications, each with unique strengths catering to different project needs and developer preferences. But for me, I went for React because it is what I want and use in every project.

1,905,510 | Life in the Clouds Exploring Venus and Beyond | Dive into the exciting research exploring the possibility of life in the clouds of Venus and other seemingly inhospitable environments. | 0 | 2024-06-29T10:22:27 | https://www.elontusk.org/blog/life_in_the_clouds_exploring_venus_and_beyond | venus, astrobiology, spaceexploration | ## Life in the Clouds: Exploring Venus and Beyond
When you think about potential habitats for extraterrestrial life, Venus might not be the first place that comes to mind. The surface of Venus is an inferno with temperatures hot enough to melt lead, and the atmospheric pressure is a crushing 92 times higher than Earth's. Yet, recent research suggests that the clouds of Venus could harbor life. How could this be possible?
### The Enigmatic Atmosphere of Venus
Venus's thick carbon dioxide atmosphere is a harsher deterrent for life on its surface. However, around 50 kilometers above, the conditions become surprisingly Earth-like—temperatures range from 30°C to 70°C and pressures drop to similar levels found at sea level on Earth.
### The Phosphine Puzzle
In September 2020, a team of researchers announced the detection of phosphine in the cloud decks of Venus. Phosphine is a molecule associated with biological processes on Earth, particularly among anaerobic organisms. The detection, made using the James Clerk Maxwell Telescope and the Atacama Large Millimeter Array, sparked intense debate. Could phosphine be a sign of microbial life?
### Life Finds a Way
Astrobiologists often chant, "Life finds a way." If microscopic life forms exist in Venus's clouds, they would have to be incredibly resilient. They'd need to endure high acidity (the clouds contain droplets of sulfuric acid) and find a way to metabolize in an environment lacking water, as we know it. However, extremophiles on Earth have astonished us time and again; some thrive in boiling hydrothermal vents, while others prosper in acidic boiling springs.
### Other Inhospitable Havens
Venus is not the only "inhospitable" location under scrutiny for harboring life.
#### **1. Europa and Enceladus:**
These icy moons of Jupiter and Saturn respectively are believed to have subsurface oceans beneath their frozen exteriors. Europa's geologically active surface and Enceladus's plumes of water vapor hint at liquid water and an energy source—key ingredients for life.
#### **2. Mars:**
Once possessing a more temperate climate, Mars is now a freezing desert. Yet, researchers hold hope for ancient microbial life, possibly preserved in underground aquifers or in the valleys where liquid water might still occasionally flow.
#### **3. Titan:**
Saturn’s moon Titan offers a methanogenic ecosystem. With rivers and lakes of liquid methane and ethane, Titan challenges our Earth-centric view of biology. Concepts like non-water-based life make Titan an intriguing subject for investigation.
### The Frontiers of Space Research
Advances in technology are enabling more sophisticated probes and rovers that can venture into these harsh environments. NASA's upcoming missions, such as the Dragonfly rotorcraft to Titan, and ESA's EnVision mission to Venus, are set to provide unprecedented data.
### A Final Thought
While life’s existence in such formidable locales is still hypothetical, the very pursuit of these answers signifies humanity's boundless curiosity and advanced technological prowess. The journey to uncover life beyond Earth’s confines could redefine our understanding of biology, chemistry, and even the concept of life itself.
So, will we find bacteria floating in the acid clouds of Venus or alien fish swimming in Europa’s ice-covered oceans? The search continues, and with each passing day, we edge closer to understanding our place in the cosmos.
Stay tuned for the future of space exploration; the universe has only begun to reveal its secrets.

1,905,503 | Lagrange Points Gateways to the Future of Space Exploration | Discover the fascinating science behind Lagrange points and explore how they can revolutionize space observatories and fuel depots. | 0 | 2024-06-29T10:06:30 | https://www.elontusk.org/blog/lagrange_points_gateways_to_the_future_of_space_exploration | space, astronomy, innovation | # Lagrange Points: Gateways to the Future of Space Exploration
Space—the final frontier. It’s not just the stuff of science fiction; it’s an ever-growing field brimming with opportunities for innovation and discovery. Today, we’re diving into a captivating concept: Lagrange points. These unique locations in space hold immense potential for the future of space-based observatories and fuel depots. Stick around to find out why!
## What are Lagrange Points?
Let’s start with the basics. Imagine two celestial bodies, like the Earth and the Moon, exerting gravitational forces. Somewhere in the cosmic dance between these two bodies, there are points where their gravitational forces and the centripetal force of an orbiting object balance out. These are the Lagrange points, named after the mathematician Joseph-Louis Lagrange who first described them in the 18th century.
There are five Lagrange points, denoted as L1 through L5. The first three (L1, L2, and L3) lie along the line connecting the two large bodies, while the remaining two (L4 and L5) form equilateral triangles with them.
### The Five Lagrange Points
1. **L1** - Located between the two celestial bodies, offering a spot for uninterrupted observation of the Sun.
2. **L2** - Found on the line beyond the smaller body, an ideal location for deep-space observations.
3. **L3** - Positioned directly opposite the smaller body, across from the larger one.
4. **L4 & L5** - Forming points of equilibrium ahead of and behind the smaller body in its orbit, maintaining a stable relationship with both bodies.
These points are unique cosmic sweet spots where gravitational forces balance so perfectly that a spacecraft can "park" there with minimal fuel consumption.
## Space-Based Observatories: A New Era
One of the most exciting applications of Lagrange points is for space-based observatories. Let’s break down why these locations are so advantageous:
### Uninterrupted Views
At points like L1 and L2, a telescope can keep a constant eye on either the Sun or the deep reaches of space without the interference of Earth’s atmosphere or magnetic field. For instance, the James Webb Space Telescope is set to be positioned at L2, allowing it to gaze into distant galaxies and star systems without any terrestrial interruptions.
### Stability and Efficiency
The stability of L4 and L5 makes them perfect spots for long-term observational missions. Instruments placed here require minimal adjustments to maintain their position, saving energy and reducing the risk of failure. Imagine a floating observatory providing continuous data streamed back to Earth—like a constant tap into the universe's secrets.
## Fuel Depots: Energizing Space Travel
Another thrilling possibility is the use of Lagrange points as fuel depots. Efficient refueling in space could be a game-changer, enabling longer missions and broader explorations. Let’s explore how this might work:
### Reduced Energy Costs
Positioning fuel depots at Lagrange points can reduce the amount of energy needed for spacecraft to reach them. The minimal gravitational forces mean less fuel is required for adjustments, providing a more cost-effective solution for deep-space missions.
### Gateway to Deep Space
Fuel depots at these points can serve as interstellar pit stops. Spacecraft heading to distant planets or even other solar systems could refuel and resupply before continuing their journey. This opens up the possibility for more ambitious missions that were previously unattainable due to fuel constraints.
### Compatibility with Automated Systems
Imagine autonomous systems managing these depots, coordinating refuel missions without the need for constant human oversight. Such systems could optimize fuel usage and ensure that spacecraft are always mission-ready.
## Conclusion
Lagrange points aren’t just theoretical constructs—they are the gateways to a new era of space exploration. From revolutionary observatories providing uninterrupted views of the cosmos to fuel depots enabling extended missions, these points hold untapped potential that could redefine our understanding and utilization of space.
So, the next time you gaze up at the night sky, remember that these seemingly invisible points of equilibrium are key to unlocking the vast wonders of our universe. Let’s keep pushing the boundaries of what’s possible, one Lagrange point at a time!

1,905,501 | The Power of Digital Payments in Upgrading Lives & Communities | While cash has long been the king of payment transactions, digital payments have brought in a new... | 0 | 2024-06-29T10:04:54 | https://dev.to/fsstech/the-power-of-digital-payments-in-upgrading-lives-communities-45fn | digitalpayments, payments | While cash has long been the king of payment transactions, digital payments have brought in a new era. Through cards, online banking, mobile wallets, real-time payments and contactless methods, digital payments have rapidly transformed the way we pay.
This shift isn’t just about convenience; it’s also about empowering individuals and communities, ultimately leading to a significant upgrade in our lives.
## Convenience at your fingertips
The most apparent benefit of digital payments is their sheer ease. Gone are the days of scrambling for exact change or worrying about carrying cash. With a few taps or swipes on your phone, we can pay for literally anything. This not only saves time but also reduces the stress associated with handling physical money.
This convenience extends beyond everyday purchases. From sending money to a family member across the country in seconds to paying a bill online without late fees, digital payments make financial management a breeze.
## Financial inclusion for all
Digital payments have the potential to bridge the financial inclusion gap, particularly for those who haven’t had access to traditional banking systems. Mobile wallets, for example, require minimal infrastructure compared to physical banks, making them accessible even in remote areas. This empowers individuals to participate in the formal economy, build credit scores, and access financial services they may not have had before.
Small businesses also benefit from digital payments. By accepting cashless transactions, they can attract a wider customer base, reduce the risk of theft, and streamline their accounting processes. This paves the way for entrepreneurship and economic growth, especially in developing economies.
## Enhanced security and transparency
Digital transactions leave a clear trail, making them more secure than cash. With features like two-factor authentication and encryption, digital payments offer greater protection against fraud and theft. Additionally, many platforms provide detailed transaction history, allowing one to track spending and manage finances effectively.
This transparency goes beyond individual users. Governments can leverage digital payments to track tax revenue and identify fraudulent activities, leading to a more efficient and accountable financial system. This fosters trust in institutions and creates a fairer economic environment.
## Boosting businesses and economies
The rise of digital payments isn’t just about individual benefits; it has a significant impact on businesses and economies as a whole. By facilitating faster transactions and reducing reliance on cash, digital payments can stimulate economic activity. This can lead to increased investment, job creation, and overall growth.
Furthermore, digital payments enable innovative business models. Online marketplaces, for instance, rely heavily on cashless transactions, creating new avenues for entrepreneurship and job creation. This fosters a more dynamic and competitive business landscape.
## Challenges and the road ahead
Despite the numerous advantages, digital payments aren’t without challenges. Ensuring internet connectivity and access to smartphones, especially in rural areas, is crucial for widespread adoption. Additionally, promoting digital literacy and addressing cybersecurity concerns are essential for building trust in the system.
There are also concerns about data privacy and potential misuse of financial information. Robust regulations and strong consumer protection measures are needed to ensure that digital payments remain a safe and secure platform for everyone.

1,905,488 | Creating your own security attribute with Symfony | Introduction Symfony security has a great feature to check authorization named Voters.... | 0 | 2024-06-29T10:02:54 | https://medium.com/@ict80/creating-your-own-security-attribute-with-symfony-769f34e199f9 | php, symfony, attribute, security | ### Introduction
[Symfony security](https://symfony.com/doc/current/security.html) has a great feature to check authorization named Voters. [Voters](https://symfony.com/doc/current/security/voters.html) are services which allows you to check user authorization in the way you need.
In this article, I would like to share with you another way to define custom authorization checking: _Create our custom security attribute_
Let’s imagine we store user roles out of the User class (the one which implements the [Symfony UserInterface](https://github.com/symfony/symfony/blob/7.1/src/Symfony/Component/Security/Core/User/UserInterface.php)) and we have a controller on which we only want to allow ROLE_SUPERUSER users.
### Creating the Attribute
Let’s create a simple attribute which receive the roles we want to allow
```php
#[\Attribute]
class IsUserGranted
{
public function __construct(public readonly array $roles){ }
}
```
### Creating the Event Subscriber
Now, let’s create a subscriber which will keep listening to _KernelEvents::CONTROLLER_ARGUMENTS_.
```php
class UserGrantedSubscriber implements EventSubscriberInterface
{
public static function getSubscribedEvents(): array
{
return [
KernelEvents::CONTROLLER_ARGUMENTS => ['onKernelControllerArguments']
];
}
public function onKernelControllerArguments(ControllerArgumentsEvent $event): void
{
$attrs = $event->getAttributes();
/** @var IsUserGranted[]|null $isUserGrantedAttrs */
$isUserGrantedAttrs = $attrs[IsUserGranted::class] ?? null;
if(!$isUserGrantedAttrs){
return;
}
$isUserGranted = $isUserGrantedAttrs[0];
// Some code to get user roles from outside the User
$roles = ['......'];
// ------------------------------------
$commonRoles = array_intersect(
$roles,
$isUserGranted->roles
);
if(count($commonRoles) === 0){
throw new AccessDeniedException('You are not granted to get this resource');
}
}
}
```
After the **KernelEvents::CONTROLLER_ARGUMENTS** event is received, the function **onKernelControllerArguments** is executed. The function gets an object of class **ControllerArgumentsEvent** as a parameter. This object gives us access to controller attributes through the **getAttributes** method. If the **IsUserGranted** attribute is present, the user roles will be compared against granted roles and, if there are no matching roles, an **AccessDeniedException** will be thrown.
### Protecting a Controller
The last step is to use our new attribute in a controller. Let’s create a controller and set it our attribute:
```php
#[IsUserGranted(roles: ["ROLE_SUPERUSER"])]
class AdminController extends AbstractController
{
#[Route('/admin/domains', name: 'get_admin_domains', methods: ['GET'])]
public function getAdminDomains(): JsonResponse
{
return new JsonResponse([
'ares.com',
'atila.com',
], Response::HTTP_OK);
}
}
```
And that’s all. If we try to access the resource with a user who does not have a **ROLE_SUPERUSER**, access will be denied.
### Conclusion
This is another way you can consider if you want to add an extra authorization layer. As I've said in the introduction, this way can be useful when you want to apply the same authorization logic to all controller actions but the [IsGranted](https://symfony.com/doc/current/security/expressions.html) attribute does not match your needs.
> PHP attributes combined with the PHP reflection capabilities are a fantastic combination that allow developers to add extra behavior to classes in a really descriptive way. In my last published book, I use attributes to mark services as API operations, mark operations as background etc. If you want to know more, you can find the book here: [https://amzn.eu/d/3eO1DDi]. | icolomina |
1,905,499 | Integrating Custom Fonts Using CSS Modules in Next.js | Learn how to incorporate and use custom fonts in your Next.js projects using CSS Modules. | 0 | 2024-06-29T10:00:21 | https://dev.to/itselftools/integrating-custom-fonts-using-css-modules-in-nextjs-cmm | nextjs, css, webdev, fonts |
At [itselftools.com](https://itselftools.com), we’ve amassed a wealth of knowledge from developing over 30 projects combining the robust capabilities of Next.js and Firebase. In this article, we’ll demonstrate how to effectively integrate custom fonts into your Next.js applications using CSS Modules, enhancing the visual richness and user experience of your sites.
## What are CSS Modules?
Before we dive into the nuts and bolts, let's briefly touch on CSS Modules. CSS Modules are a popular approach in the web development community used for styling components. They allow you to write CSS that is scoped locally to the component rather than globally. This means class names and animations are scoped locally by default and do not conflict with other styles in the application.
## Using Custom Fonts with CSS Modules in Next.js
To implement custom fonts in your Next.js project, you can follow these steps, which involve using a CSS Module file:
#### Step 1: Define Your Font-face
In your `.module.css` file, you will declare your `@font-face` like this:
```css
.module.css
@font-face {
font-family: 'MyCustomFont';
src: url('/fonts/my-font.woff2') format('woff2');
}
```
This defines the family name of your font and specifies the location and format of the font file, ensuring the browser can correctly load and render it. The `woff2` format is often recommended due her | antoineit |
1,905,500 | How Should A Leather Cafe Racer Jacket Fit | The leather cafe racer jacket, with its sleek silhouette and rebellious spirit, is a timeless fashion... | 0 | 2024-06-29T10:00:21 | https://dev.to/merryjhon1/how-should-a-leather-cafe-racer-jacket-fit-229a | The [leather cafe racer jacket](https://yolojackets.com/product/mens-quilted-leather-jacket/), with its sleek silhouette and rebellious spirit, is a timeless fashion piece. But nailing the perfect look depends on a crucial factor – fit. Unlike a baggy bomber or a loose-fitting trucker jacket, a cafe racer should feel like a second skin, offering both comfort and a touch of edgy coolness. Let's explore how a leather cafe racer jacket should ideally fit for maximum style and functionality.
## The Essence of the Fit: Snug Yet Mobile
The defining characteristic of a cafe racer jacket's fit is its snugness. This harkens back to its motorcycle racing roots, where a close-fitting jacket allowed riders to tuck themselves over the fuel tank for a more aerodynamic position. This slim profile persists as a key element of the cafe racer aesthetic, creating a clean and streamlined look.
However, snug shouldn't translate to restrictive. A well-fitting cafe racer jacket should allow for a comfortable range of motion. You should be able to raise your arms without feeling constricted, and the jacket shouldn't bunch up uncomfortably when you sit down. This balance between a close fit and ease of movement is crucial for both style and practicality.
## Key Areas to Consider for the Perfect Fit:
Shoulders: The shoulders should sit comfortably without feeling tight. The seam should sit flush with the natural curve of your shoulder bone. Avoid jackets with excess fabric bunching up around the shoulder area.
Chest and Torso: The jacket should hug your chest without feeling restrictive. You should be able to comfortably button it up without feeling like you're straining. Ideal sizing allows for a thin layer underneath, like a t-shirt or a light sweater.
Length: Traditionally, cafe racer jackets are cropped, typically ending at or slightly above the waistline. This allows for a more dynamic look and greater freedom of movement when riding. However, modern interpretations offer longer lengths for those who prefer a more covered silhouette. Choose a length that flatters your body type and reflects your personal style.
Sleeves: The sleeves should ideally end at your wrist bone or slightly above. This allows for a clean, finished look and prevents the sleeves from bunching up over your hands.
## Leather's Role in the Fit Equation
Leather is a natural material that offers a unique benefit regarding fit – it conforms to your body shape over time. This means a slightly snug cafe racer jacket might feel perfect after a few wears as the leather breaks in and molds to your figure. However, keep in mind that significant stretching is unlikely. Opt for a jacket that feels comfortable with a little room for movement when new.
## Finding the Perfect Fit: Tips and Tricks
Finding a cafe racer jacket with the perfect fit can be challenging, especially when shopping online. Here are some tips to help you out:
Consult Size Charts: Pay close attention to the retailer's size chart and measurements. Measure yourself carefully, particularly your chest, shoulders, and arm length, and compare them to the listed measurements.
Consider Reviews: Read customer reviews to get insights into the fit of specific jackets. Look for reviews that mention sizing and how the jacket feels on the body.
Don't Hesitate to Ask: If you're unsure about sizing, contact the retailer directly. They might be able to offer advice based on your measurements and desired fit.

2. [Understanding Basic Syntax](#understanding-basic-syntax)
3. [Exploring Data Structures](#exploring-data-structures)
4. [Mastering Object-Oriented Programming](#mastering-object-oriented-programming)
### Getting Started with Python
Before we write our first line of code, let's set up our Python environment.
#### Installation
1. **Download Python**: Head over to the [official Python website](https://www.python.org/), and download the latest version compatible with your operating system.
2. **Install Python**: Follow the installation wizard to set up Python on your machine. Make sure to check the box that says "Add Python to PATH".
3. **Verify Installation**: Open your terminal or command prompt and type:
```sh
python --version
```
If it displays the Python version you installed, you are good to go!
#### Setting Up an IDE
For an efficient coding experience, we recommend using an Integrated Development Environment (IDE). [VSCode](https://code.visualstudio.com/) and [PyCharm](https://www.jetbrains.com/pycharm/) are excellent options to start with.
### Understanding Basic Syntax
Let's dive into the ocean of Python's basic syntax. It's simple yet powerful!
#### Hello, World!
The quintessential Beginners program:
```python
print("Hello, World!")
```
This single line prints the text "Hello, World!" to the console. Simple, right?
#### Variables and Data Types
Python dynamically assigns data types to variables. Here’s how to declare variables:
```python
name = "Alice" # String
age = 25 # Integer
height = 5.6 # Float
is_student = True # Boolean
```
Understanding data types helps in making your code robust and error-free.
#### Basic Operations
```python
# Arithmetic operations
a = 10
b = 5
print(a + b) # Addition
print(a - b) # Subtraction
print(a * b) # Multiplication
print(a / b) # Division
```
### Exploring Data Structures
Data structures are fundamental for storing and organizing data efficiently. Let's explore common Python data structures.
#### Lists
A list is a collection of items which is ordered and changeable.
```python
fruits = ["apple", "banana", "cherry"]
fruits.append("orange") # Adding an item
print(fruits)
```
#### Tuples
A tuple is similar to a list but immutable.
```python
colors = ("red", "green", "blue")
print(colors[1]) # Accessing item
```
#### Dictionaries
A dictionary stores values in key-value pairs.
```python
person = {
"name": "Alice",
"age": 25,
"city": "New York"
}
print(person["name"]) # Accessing value by key
```
### Mastering Object-Oriented Programming
Object-Oriented Programming (OOP) is a paradigm based on the concept of objects.
#### Classes and Objects
A class is a blueprint for creating objects.
```python
class Dog:
def __init__(self, name, age):
self.name = name
self.age = age
def bark(self):
print(f"{self.name} is barking")
my_dog = Dog("Buddy", 3)
my_dog.bark()
```
Here, `Dog` is a class, and `my_dog` is an object of the `Dog` class.
#### Inheritance and Polymorphism
Inheritance allows one class to inherit attributes and methods from another class.
```python
class Animal:
def __init__(self, species):
self.species = species
def make_sound(self):
pass
class Cat(Animal):
def __init__(self, name):
super().__init__("Cat")
self.name = name
def make_sound(self):
print(f"{self.name} says Meow!")
my_cat = Cat("Whiskers")
my_cat.make_sound()
```
With inheritance, `Cat` inherits properties from the `Animal` class and adds its own behavior.
### The Road Ahead
Congratulations on embarking on your Python journey! This is just the beginning. The world of Python is vast and full of opportunities to create something amazing. Stay tuned for the next parts of this series, where we will delve deeper into each topic and provide hands-on projects to solidify your knowledge.
Happy coding! 🚀 | quantumcybersolution |

You can get more information about the program [here](https://hng.tech/internship).
A few weeks before getting into the internship I faced a challenge while integrating Flutterwave and korapay payment gateway. “I want to use a single form to request for the amount a user wants to pay and have a select drop down to select the payment gateway they are paying with and it should instantly redirect them”
Using html, css and Js(Ajax) for the frontend and Laravel for the backend, I came up with a solution.
I wrote a JavaScript code to get the amount and the method of payment selected, followed by a switch statement to redirect the user to the gateway payment page based on the gateway selected.
For flutterwave integration: There is a callback function to redirect to the callback URL with the transaction reference and status as a param in the url(user/flutterwave/reference/success) after a successful or failed transaction, the callback url is the backend endpoint for verifying the transaction by requesting the flutterwave verification endpoint sending the transaction reference as a post request, this request returns a json data, I proceeded to check if the transaction status is successful and got the amount paid then I can finally credit the user. If it's a failed transaction I created a notification to notify the user instantly.
**My goal for the HNG Internship**
I am on the Backend Development track therefore one of my goals is to be able to put my skills into practice, connect and learn from other developers.
You can also decide to join HNG premium [here](https://hng.tech/premium), and below are the perks for it:
Network with other HNG finalists
Access exclusive opportunities
Collaborate on projects
Job recommendation and certificate.

1,905,431 | From React to TypeScript, Simplifying Migration with ts-migrate | Migrating a React.js project to TypeScript can significantly enhance your codebase by adding static... | 0 | 2024-06-29T09:42:30 | https://dev.to/sustiono/from-react-to-typescript-simplifying-migration-with-ts-migrate-56g8 | typescript, react, javascript, frontend | Migrating a React.js project to TypeScript can significantly enhance your codebase by adding static type checking, improving maintainability, and reducing runtime errors. In this article, I will walk you through the migration process using the `ts-migrate` library, covering both full and partial migration approaches.
> **Note:** This article assumes that your project is managed using Yarn instead of npm. If you're using npm, please adjust the commands accordingly.
## Required Libraries
Before starting the migration, make sure you have the following libraries installed:
- `typescript`
- `ts-migrate`
- `@types/react`
You can install these dependencies using Yarn:
```
yarn add typescript ts-migrate @types/react --dev
```
## Migration Process
The `ts-migrate` library provides two options for migration: full migration and partial migration. Full migration converts the entire codebase to TypeScript at once, while partial migration allows you to convert specific parts of the codebase incrementally.
**1. Full Migration**
- Initialize tsconfig file.
Start by initializing the TypeScript configuration file (tsconfig.json) with the following command:
```
yarn tsc --init
```
- Update tsconfig. Replace the content of tsconfig.json with the values from [tsconfig.base.json](https://github.com/airbnb/ts-migrate/blob/master/tsconfig.base.json).
- Run the Migration Command. Execute the full migration using the following command:
```
yarn ts-migrate-full ./
```
- Check for Errors. Start the local server and check for any broken code:
```
yarn dev
```
If any errors are detected, fix them manually until the code runs well.
**2. Partial Migration**
- Initialize tsconfig. Initialize the TypeScript configuration file in the root folder:
```
yarn tsc --init
```
- Update tsconfig. Replace the content of tsconfig.json with the values from [tsconfig.base.json](https://github.com/airbnb/ts-migrate/blob/master/tsconfig.base.json).
- Initialize tsconfig for the Target Folder. Initialize a tsconfig file in the folder you want to migrate:
```
yarn ts-migrate init:extended <folder>
```
- Update Folder-Specific tsconfig. Update the configuration in the newly created tsconfig file according to your needs.
- Run the Migration Command. Migrate the specific folder:
```
yarn ts-migrate-full <folder>
```
- Check for Errors. Start the local server and check for any broken code:
```
yarn dev
```
If any errors are detected, fix them manually until the code runs well.
## Defining Types & Fixing Other Code Issues
After migration, you might encounter some type of errors. Search your codebase for `// @ts-expect-error` comments and fix the corresponding errors as needed.
Here is a step-by-step approach:
**1. Locate Errors**
Search for occurrences of `// @ts-expect-error` in your codebase.
**2. Fix Errors**
Review the errors and define the appropriate types or make necessary code adjustments to resolve them.
## Pros and Cons of Full and Partial Migration
### Full Migration
**Pros:**
- **Consistency**
Ensures the entire codebase is consistent with TypeScript at once.
- **Immediate Benefits**
You get all the benefits of TypeScript (type checking, better tooling, etc.) across your whole project immediately.
- **Simpler Tooling**
Easier to configure tools and build processes for a single codebase language.
**Cons:**
- **High Initial Effort**
Requires significant upfront work to migrate the entire codebase.
- **Potential for Disruption**
Higher risk of introducing bugs or breaking changes in a large migration.
- **Resource Intensive**
May require more resources (time, developers) to complete the migration quickly.
### Partial Migration
**Pros:**
- **Incremental Approach**
Allows gradual migration, reducing immediate workload.
- **Less Risk**
Lower risk of introducing bugs or breaking changes, as you migrate and test small parts of the codebase.
- **Flexible Scheduling**
Easier to fit into regular development cycles without significant disruption.
**Cons:**
- **Mixed Codebase**
You may have a mixed codebase (JavaScript and TypeScript) for a longer period.
- **Complex Tooling**
Requires careful configuration of tools and build processes to handle both JavaScript and TypeScript.
- **Delayed Benefits**
You won’t fully realize the benefits of TypeScript until the entire codebase is migrated.
## Why Use `ts-migrate` Over Manual Migration?
Using `ts-migrate` for your TypeScript migration offers several advantages over manual migration:
**1. Automation**
`ts-migrate` automates many repetitive tasks involved in migrating code to TypeScript. This reduces the time and effort required compared to manual migration, where each file and type definition would need to be handled individually.
**2. Consistency**
The tool ensures a consistent migration approach across your entire codebase. This reduces the risk of human error and helps maintain a uniform coding style, which is harder to achieve with manual migration.
**3. Efficiency**
`ts-migrate` can handle large codebases efficiently. It processes multiple files concurrently, making the migration faster than manually updating each file one by one.
**4. Error Handling**
The tool automatically inserts `// @ts-expect-error` comments where type errors occur, allowing you to identify and fix these issues at your own pace. This helps in managing and prioritizing the resolution of type errors systematically.
**5. Incremental Migration Support**
`ts-migrate` supports both full and partial migration strategies. This flexibility allows you to choose the approach that best suits your project’s size, complexity, and deadlines, something that is more challenging to manage manually.
## Comparison: Manual Migration vs. ts-migrate
| **Feature** | **Manual Migration** | **ts-migrate** |
|------------|----------|-----------|
|**Automation** | Low - Manual updates needed for each file | High - Automates repetitive tasks|
| **Consistency** | Varies - Dependent on individual efforts | High - Ensures consistent migration approach |
|**Efficiency** | Low - Time-consuming for large codebases | High - Processes multiple files concurrently |
| **Error Handling** | Manual - Developers must identify and fix errors | Automated - Inserts `// @ts-expect-error` for easy identification |
| **Flexibility** | Low - Full migration is more manual | High - Supports both full and partial migration|
| **Risk of Human Error** | High - Prone to inconsistencies | Low - Reduces human error through automation |
## Choosing the Right Migration Strategy
Deciding between full and partial migration depends on several factors:
**1. Project Size and Complexity**
For large, complex projects, partial migration might be more manageable, allowing you to gradually convert the codebase without overwhelming the team. For smaller projects, full migration can be quicker and more straightforward.
**2. Team Experience and Resources**
Assess your team’s familiarity with TypeScript and available resources. If your team is experienced with TypeScript and you have the capacity to handle a large migration effort, a full migration might be feasible. If your team is less familiar with TypeScript or resources are limited, a partial migration allows for a more controlled and incremental approach.
**3. Project Deadlines and Workflow**
Consider your project timelines and workflow. If you have tight deadlines, partial migration might be less disruptive, allowing you to continue delivering features while gradually introducing TypeScript. Full migration might be suitable if you have a window of time to focus on the migration effort without impacting other deliverables.
**4. Risk Tolerance**
Evaluate your tolerance for potential disruption. Full migration introduces more immediate changes, which can be risky but also delivers immediate benefits. Partial migration spreads the risk over a longer period, providing opportunities to address issues incrementally.
By considering these factors, you can choose the migration strategy that best suits your project’s needs and your team’s capabilities.

## Ramping up quickly matters
Assuming an engineer's median tenure is [**2-2.5 years**](https://www.zippia.com/software-engineer-jobs/demographics/), ramping up quickly **matters**.
I believe a new dev should be delivering value after **4 weeks** of **intensive, planned** onboarding.
Consider an alternative, where value is delivered after six months. A five-month delay accounts for **20% loss** of an employee's budget. fun [numbers](https://media.licdn.com/dms/image/D4E12AQGxxxY9VeVt2w/article-inline_image-shrink_1000_1488/0/1658695632487?e=1722470400&v=beta&t=wraGVDd8YiFDiGzB8mn9Wvwj9bQwEUvAJ4B-FwrzTJg)
Following below ideas, you can create your own team-specific onboarding plan:
## Methodology:
1. **Managers responsibility:** ramping up is 100% **managers job**. Free up your time and take it seriously.
2. **Task oriented**: create a Story ticket, with relevant sub-tasks owned by dev, committed to current **Sprint**.
3. **Hands-on**: onboarding includes code and **production tasks from the very beginning** (think ['bootcamp'](https://engineering.fb.com/2009/11/19/production-engineering/facebook-engineering-bootcamp/)). We'll start with a code-task to align standards and conventions and move quickly to production tasks.
4. **Prod tasks** can be either: `{bug, refactor, small-feature, infra imprv}`.
5. **Duration:** 4x weeks, 2w for logistics, dev-task and learning. another 2w for prod tasks.
6. **Identify early** low performers. bad hires happen, don't drag this too long and try to find red flags from the very begining.
7. **Identify early** technical weakness, areas of improvements and adjust the onboarding plan accordingly ("New hire never queried a DB").
8. **Ceremonies alignment:** this is the time to align on: time estimations, technical design, code review and Daily. New hire report's progress on **Daily**.
9. **Conventions alignment:** pushes code into a sample repository, following existing standards and validated by code review.
10. **1x Buddy / Context**: define a Senior developer that will follow new hire. Every question should go to him, we'd like to minimize overall teams context-switch. This is also a chance to let "potential leaders" an option to mentor others.
11. **Self led**: it is expected from hire to own and run plan independently. Should not **drain** other peoples time.
12. [**Brook's law:**](https://en.wikipedia.org/wiki/Brooks%27s_law) do not engage **with critical prod** tasks at the beginning.
13. **Get to know your colleagues:** engage with existing team members via **learning sessions**, where team members teach you a technical related subject and relationships are built ("Backend Services Overview").
14. **Local environment**: invest time installing local env early on. Verify you have a simple **"how-to" document.**
15. **Sanity checks:** schedule check-ins to verify things are as expected and verify: `{Do you want to pair more? Do you want more alone time? Are there particular areas you need more guidance in?}`.
16. **Retrospective:** conduct retrospective meeting, **collect data**, feedback and adjust plan accordingly.
18. **Serves a dual purpose:** an opportunity to demonstrate new hire that they have joined a professional environment.
```
"Most bootcamp graduates agree that the most valuable part of bootcamp is the tasks they are assigned.
Engineers have real work assigned to them the first time they open their laptops and many push code to the live site within their first week."
(Boz, 2009)
```

Today we will discuss about object!
## OBJECT:
==>Object are created from a Class.
==>An Object is a Real world entity.
==>In order to Create a class object first we need to write "**new**" keyword and initialize that object with the help of a constructor, constructor name will be same as class name.
==>We can create any number of object from a Class.
**Example:**
ClassA aobj = new ClassA(); //ClassA object
ClassB bobj = new ClassB(); //ClassB object
ClassC cobj = new ClassC(); //ClassC object
> I write a **simple program** to understand the how to create **Class Object.**
`public class First
{
public void msg()
{
System.out.println("HELLO WORLD");
}
private void display()
{
System.out.println("java is awesome");
}
public static void main(String[] args)
{
System.out.println("Start");
First obj=new First(); //Creating an object
obj.msg(); //Calling a method
obj.display(); //calling a method
System.out.println("End");
}
}
`
**OUTPUT:**
Start
HELLO WORLD
java is awesome
End
Every Program to Run in java we can do 2 specific tasks:
1)Compilation
2)Running
## Compilation:
[**java Compiler==>javac Filename.java**]
- Here Compilation do Java Compiler, java Compiler Command is Javac Filename.java.
- Compilation means checking the code whether we have written according to the java language Syntax or not.
- After **Successful Compilation** java Compiler is going to generate a **.Class file** .
- The generated .Class File name will be same as Class name.
- The generated .Class file Consists of bytecode instructions which are understand only by the machines , humans Can not understand them.
## Running:
[**JVM**(Java Virtual Machine)==>**java generated .Class File name**]
- In order to **run our java program** we need to send our generated .Class File as input to the JVM.
- JVM is going to check whether all the byte code instructions present in the .Class file are Correct Or Wrong **if Correct** will be getting **Output** if **Wrong** we will be getting an **Exception**.

1,905,485 | Step By Step Process Of Tackling a Complex Backend Challenge: Implementing Email Notifications with Nodemailer | Ensuring smooth user communication is essential for backend developers to create reliable... | 0 | 2024-06-29T09:37:00 | https://hng.tech/internship | Ensuring smooth user communication is essential for backend developers to create reliable applications. Using the Nodemailer package, I recently overcame a complicated problem that tested my knowledge and rekindled my interest in backend development: sending email notifications for user registration and password changes. I'm excited to start a new chapter in my career with the HNG Internship, which coincides with this experience. I'll describe a challenging backend issue I ran into recently and how I resolved it in this post, emphasizing my methods, choices I made in terms of technology, and abilities I applied.
**The Problem: Implementing Email Notifications for User Registration and Password Changes**
The challenge was to use Nodemailer to create a reusable email notification system code that would send confirmation emails to users upon registration or password changes. The system had to make sure that users received notifications on time and manage email delivery effectively. Here are the steps that I utilized:
**Step 1: Analyzing the Requirements**
Understanding the use cases and conducting a thorough analysis of the requirements was the first stage in sending emails.
**Requirements:**
- Send a verification email(that contains a link) to users upon registration so their email can be verified and allow them access to their account
- Send a notification email(change password link) to users when they
want to change their password.
- Ensure the emails are delivered reliably and efficiently.
- Handle potential errors and retries gracefully.
**Step 2: Setting Up Nodemailer**
With my requirements clear and as a beginner, I surfed the net and GitHub to get the requirements. Then I came across **Nodemailer**, read the documentation and implemented it
- **Steps Taken:**
1. *Installation:* Installed Nodemailer using npm.
2. *Configuration:* Configured Nodemailer with SMTP settings for the email service provider (e.g., Gmail, SendGrid).
**Step 3: Develop the Email Sending Functionality**
Next, I developed the functionality to send emails for registration and password change events.
**Steps Taken:**
1. *Email Templates:* Created email templates for registration confirmation and password change notifications.
2. *Email Sending Function:* Developed a function to send emails using the configured transporter.
**Step 4: Integrating with User Registration and Password Change Logic**
The next step was to integrate the email-sending functionality with the user registration and password change logic.
**Steps Taken:**
1. *User Registration:* Modified the user registration endpoint to send a confirmation email upon registration, to verify the email.
2. *Password Change:* Updated the password change endpoint to send a notification email when the password is about to be changed.
**Step 5: Testing and Monitoring**
To ensure effective email delivery, I lastly carefully tested the implementation and kept an eye out for any problems.
1. *Testing:* To make sure emails were sent appropriately, the email sending capability was tested both manually and automatically.
2. *Monitoring:* To follow email delivery and address any issues or retries as necessary, set up logging and monitoring.
**Myself**
I am just a graduate of the University of Lagos with a BSc. in Civil Engineering but I'm just in love with coding I learned my backend skills from DevCareer and got my certificate a few months back. So joining the HNG internship feels like the next step in my backend career
**Why HNG Internship?**
One of the most important things I have done as a backend engineer is to start the HNG internship. Here are the reasons I am thrilled about this chance:
- *Learning and Growth:* The HNG Internship offers a special fusion of practical assignments and guidance, creating the perfect setting for me to hone my soft skills and technical competence.
- *Collaboration and Community:* It is really beneficial to be a part of a lively group of experienced professionals and like-minded people. I can't wait to work with you, impart information, and develop together.
- *Progress in Career:* My professional aspirations are well aligned with this internship, which exposes me to industry best practices and cutting-edge technologies, making me more prepared for difficulties in the future.
To also benefit or learn more about HNG, join me through this link [HNG](https://hng.tech/internship) and [here](https://hng.tech/premium)
**Conclusion**
Using Nodemailer to implement email notifications needed technical know-how, a logical approach, and ongoing learning.

We're going to make a simple blogging platform where users can read, publish and comment on articles.
## Prerequisites
- [Node.js](https://nodejs.org/en/download/package-manager) >= v18
- [MongoDB](https://www.mongodb.com/docs/manual/installation/) listening on localhost:27017
- [ts-node](https://www.npmjs.com/package/ts-node) or your favorite frontend framework
---
## Installation
First, let's set up our app by following [Eicrud's documentation](https://docs.eicrud.com/installation/).
We create a new [NestJS](https://nestjs.com/) application.
```bash
npm i -g @nestjs/cli
nest new myblog
cd myblog
```
Then install [Eicrud](eicrud.com) on top of it.
```bash
npm i -g @eicrud/cli
eicrud setup mongo myblog
```
Finally, we generate a secret key and store it in a `.env` file at the root of our project.
```bash
echo "JWT_SECRET=$(node -e "console.log(require('crypto').randomBytes(256).toString('base64'));")" > .env
```
Now we already have a well-structured project! You can check that everything is working.
```bash
npm run start
```
## Services
The [CLI](https://www.npmjs.com/package/@eicrud/cli) already generated a `User` service for us in `src\services\user`. All we need to add to our application is an `Article` service and a `Comment` service.
```bash
eicrud generate service Article
eicrud generate service Comment
```
## Model definition
Let's edit our entities to our liking.
Update the file `src\services\article\article.entity.ts` with the following.
```typescript
import { Entity, PrimaryKey, Property,
ManyToOne } from "@mikro-orm/core";
import { IsString, IsOptional } from "class-validator";
import { CrudEntity } from "@eicrud/core/crud";
import { User } from "../user/user.entity";
import { $MaxSize } from "@eicrud/core/validation";
@Entity()
export class Article implements CrudEntity {
@PrimaryKey({ name: '_id' })
@IsString()
@IsOptional()
id: string;
@ManyToOne(() => User)
@IsString()
author: User | string;
@Property()
@IsString()
title: string;
@Property()
@IsString()
@$MaxSize(1000)
content: string;
@Property()
createdAt: Date;
@Property()
updatedAt: Date;
}
```
And don't forget our `Comment` entity in `src\services\comment\comment.entity.ts`.
```typescript
import { Entity, PrimaryKey, Property, ManyToOne } from "@mikro-orm/core";
import { IsString, IsOptional } from "class-validator";
import { CrudEntity } from "@eicrud/core/crud";
import { Article } from "../article/article.entity";
import { User } from "../user/user.entity";
import { $MaxSize } from "@eicrud/core/validation";
@Entity()
export class Comment implements CrudEntity {
@PrimaryKey({ name: '_id' })
@IsString()
@IsOptional()
id: string;
@ManyToOne(() => Article)
@IsString()
article: Article | string;
@ManyToOne(() => User)
@IsString()
author: User | string;
@Property()
@IsString()
@$MaxSize(200)
content: string;
@Property()
createdAt: Date;
@Property()
updatedAt: Date;
}
```
## Access rules
Now that we have our model, let's update the access rules in `src\services\article\article.security.ts`. We want everyone to read our articles, but only their author should be able to modify them.
```typescript
guest: {
async defineCRUDAbility(can, cannot, ctx) {
// guests can read all articles
can('read', article)
}
},
user: {
async defineCRUDAbility(can, cannot, ctx) {
// user can manage their own articles
can('crud', article, { author: ctx.userId })
}
}
```
It's the same idea for comments, except this time we don't want users to modify their comments after creation. Let's change the rules in `src\services\comment\comment.security.ts`.
```typescript
guest: {
async defineCRUDAbility(can, cannot, ctx) {
// guests can read all comments
can('read', comment)
}
},
user: {
async defineCRUDAbility(can, cannot, ctx) {
// user create and delete their own comments
can('cd', comment, {author: ctx.userId})
}
}
```
## Commands
Eicrud has [prebuilt commands](https://docs.eicrud.com/user/service/#account-creation) for account creation and login. We just need to allow their usage in `src\services\user\cmds\create_account\create_account.security.ts`.
```typescript
guest: {
async defineCMDAbility(can, cannot, ctx) {
// can create an account with the role 'user'
can(create_account, user, {role: 'user'})
}
}
```
And in `src\services\user\cmds\login\login.security.ts`.
```typescript
guest: {
async defineCMDAbility(can, cannot, ctx) {
// Define abilities for user
can(login, user)
}
}
```
Now our backend is ready for action! Let's start the server and switch to another terminal.
```bash
npm run start
```
## Calling the API
To simulate our frontend we're going to use [ts-node](https://www.npmjs.com/package/ts-node), but you can use your favorite framework or tools like [esbuild](https://esbuild.github.io/) if you prefer.
```bash
npm i -g ts-node # make sur to install it globally
```
Let's install [Eicrud's client](https://docs.eicrud.com/client/setup).
```bash
npm i @eicrud/client
```
Create a file `front.ts` and start with a helper class to make Eicrud's client dynamic.
```typescript
import { ClientConfig, CrudClient } from "@eicrud/client";
export class DynamicClient {
crudClient: CrudClient<any>;
constructor() {
const initalConfig: ClientConfig = {
url: 'http://localhost:3000',
serviceName: 'user',
}
this.crudClient = new CrudClient(initalConfig);
}
get(serviceName){
this.crudClient.config.serviceName = serviceName;
return this.crudClient;
}
}
```
Now we can create our first account and publish an article.
```typescript
// ... following in front.ts
import { ICreateAccountDto } from '@eicrud/shared/interfaces';
import { ILoginDto } from '@eicrud/shared/interfaces';
import { Article } from "./src/services/article/article.entity";
async function main() {
const client = new DynamicClient();
// Create account and publish article
const dto: ICreateAccountDto = {
email: 'new.user@mail.com',
password: 'p4ssw0rd',
role: 'user',
};
const { userId } = await client.get('user').cmdS('create_account', dto);
console.log('User created!', userId);
const loginDto: ILoginDto = {
email: 'new.user@mail.com',
password: 'p4ssw0rd',
};
await client.get('user').login(loginDto);
const newArticle: Partial<Article> = {
title: 'New article',
content: 'This is a new article',
author: userId,
};
await client.get('article').create(newArticle);
// Let's check that our article was created
const userArticles = await client.get('article').find({ author: userId });
console.log('User articles:', userArticles);
}
main();
```
And let's run our frontend to test our API.
```bash
ts-node front.ts
```
That's all for the basics!
Take note of all the [CRUD operations](https://docs.eicrud.com/client/operations) available to the client. You can use any of them to query the `'article'` or `'comment'` service.
If you've had any trouble with this tutorial check out the [completed project](https://github.com/eicrud/eicrud-tutorial) on GitHub.
## Going further
Eicrud is in active development and has many features to make your life easier. You can learn all about it in the [documentation](https://docs.eicrud.com). If you find any issue don't hesitate to [create one](https://github.com/eicrud/eicrud/issues) and I'll look into it.

They can seem... | 0 | 2024-06-29T09:25:15 | https://dev.to/alisamirali/understanding-javascript-closures-53pc | javascript, webdev, frontend, softwaredevelopment | JavaScript closures are a fundamental concept that every developer should understand.
They can seem complex at first, but once you grasp the concept, you'll realize how powerful they are for writing efficient and clean code.
This article aims to demystify closures by explaining what they are, how they work, and providing practical examples of their use.
---
##📌 What is a Closure?
A closure is a feature in JavaScript where an inner function has access to its outer enclosing function’s variables. The closure has three scopes:
1- **Local Scope:** Variables defined within its function.
2- **Outer Function’s Scope:** Variables defined in the outer function.
3- **Global Scope:** Variables defined in the global scope.
Closures allow a function to access variables from an enclosing scope even after that scope has finished executing.
This means that a function retains access to its lexical scope, which is the environment in which it was created.
---
##⭐️ How Do Closures Work?
_To understand closures, let’s look at a simple example:_
```js
function outerFunction() {
let outerVariable = 'I am from the outer function';
function innerFunction() {
console.log(outerVariable);
}
return innerFunction;
}
const myClosure = outerFunction();
myClosure(); // Outputs: I am from the outer function
```
In this example, `outerFunction` defines a variable `outerVariable` and an inner function `innerFunction`.
The `innerFunction` logs `outerVariable` to the console.
When `outerFunction` is called, it returns the `innerFunction`, which is then assigned to `myClosure`.
Even though `outerFunction` has finished executing, `myClosure` still has access to `outerVariable` because of the closure.
---
##⚡️ Practical Uses of Closures
**Closures are useful in many scenarios, including:**
### 1. Data Privacy
Closures can be used to create private variables.
By defining variables within a function scope and returning an inner function that accesses these variables, you can create private variables that cannot be accessed directly from the outside.
```js
function createCounter() {
let count = 0;
return function() {
count++;
return count;
};
}
const counter = createCounter();
console.log(counter()); // 1
console.log(counter()); // 2
console.log(counter()); // 3
```
In this example, `count` is a private variable that can only be accessed and modified through the returned function.
---
###2. Function Factories
Closures can be used to create function factories—functions that return other functions. This is useful for creating functions with predefined behavior.
```js
function createAdder(x) {
return function(y) {
return x + y;
};
}
const addFive = createAdder(5);
console.log(addFive(10)); // 15
console.log(addFive(20)); // 25
```
Here, `createAdder` returns a function that adds a given number to `x`, demonstrating how closures can capture and use arguments from their outer scope.
---
###3. Maintaining State in Asynchronous Code
Closures are also useful in asynchronous code, such as callbacks and event handlers, where maintaining state is crucial.
```js
for (var i = 1; i <= 3; i++) {
setTimeout(function() {
console.log('i:', i);
}, 1000 * i);
}
// Outputs: i: 4, i: 4, i: 4 (incorrect due to var's function scope)
```
To correct this, we can use a closure to capture the current value of `i`:
```js
for (let i = 1; i <= 3; i++) {
setTimeout(function() {
console.log('i:', i);
}, 1000 * i);
}
// Outputs: i: 1, i: 2, i: 3 (correct due to let's block scope)
```
Alternatively, with `var`, we can achieve the same result using an immediately invoked function expression (IIFE):
```js
for (var i = 1; i <= 3; i++) {
(function(i) {
setTimeout(function() {
console.log('i:', i);
}, 1000 * i);
})(i);
}
// Outputs: i: 1, i: 2, i: 3
```
---
---
##Conclusion ✅
JavaScript closures are a powerful feature that allows functions to access variables from their enclosing scope even after that scope has finished executing.
They are essential for creating private variables, function factories, and maintaining state in asynchronous code.
By understanding and leveraging closures, you can write more efficient and maintainable JavaScript code.
Whether you're new to JavaScript or looking to deepen your understanding, mastering closures will enhance your ability to solve complex problems and write cleaner code.

Angular and Vue.js, offer distinct advantages depending on project requirements and team preferences
## Vue.JS
Vue.js the brainchild of Evan You has revolutionised frontend development with it’s intuitive and adaptable nature. Dubbed the “progressive framework”, Vue.js empowers developers to seamlessly integrates its features into their projects, at their own pace
Vue.js adopts a modular component based architecture, similar to React , promoting a structured and maintainable codebase.Vue’s reactivity system automatically updates the DOM when data changes ,similar to React’s virtual DOM, ensuring efficient rendering and optimal performance
One of Vue.js standout features is it’s single file components which encapsulates HTML,JavaScript, and CSS within a single file.This improves readability and enhances development speed
## Angular
Angular, developed by Google, is a comprehensive framework designed for building dynamic web applications. Released in 2010 (initially as AngularJS), it has undergone significant evolution, leading to the development of Angular (the modern version) in 2016
Angular synchronizes data between the model and the view, ensuring that any changes in the model reflect immediately in the view and vice versa.
Angular has a built-in dependency injection system, which makes it easier to develop, understand, and test applications.
## A comparison of Angular and Vue
Angular is a comprehensive framework with a steep learning curve, suited for large, complex applications. Vue.js, on the other hand, is simpler and more flexible, making it easier for beginners to learn and use.
Vue.js’ smaller size and virtual DOM make it faster and more efficient for smaller applications. Angular’s extensive feature set can introduce more overhead but provides powerful tools for building and managing large applications.
Angular, backed by Google, has a larger enterprise community and a robust ecosystem. Vue.js, while not backed by a tech giant, has quickly built a passionate and active community.
Working with React has been an enjoyable experiment or me even though I just started I will really want to learn more about react at the HNG internship if you would like to join e you can join me using any of these links
https://hng.tech/internship
https://hng.tech/premium
At HNG, I look forward to continuing to hone my skills in React, exploring new patterns and practices, and contributing to exciting projects.

1,905,445 | Harvesting the Stars The Future of Space Agriculture | Explore the challenges and groundbreaking opportunities in developing space agriculture for long-duration missions and space habitats. | 0 | 2024-06-29T09:18:38 | https://www.elontusk.org/blog/harvesting_the_stars_the_future_of_space_agriculture | space, agriculture, innovation | # Harvesting the Stars: The Future of Space Agriculture
As humanity sets its sights beyond Earth, the challenge of sustaining long-duration space missions and establishing space habitats becomes increasingly crucial. One of the key components in this cosmic puzzle is the development of space agriculture—growing food in the extraterrestrial environment. This endeavor is not just about feeding astronauts; it is about creating self-sustaining ecosystems in space. So, let's dive into the thrilling world of space farming, where sci-fi dreams meet cutting-edge science!
## The Cosmic Garden: Opportunities for Space Agriculture
### 1. Bioregenerative Life Support Systems
At the heart of space agriculture are bioregenerative life support systems (BLSS), which leverage the natural processes of plants and microbes to purify water, recycle nutrients, and produce food. By incorporating these systems, we could create closed-loop habitats where waste becomes a resource and every drop of water is reused.
### 2. Off-Earth Resources Utilization
The Moon and Mars have abundant resources that can be harnessed for agricultural purposes. Lunar regolith, for example, contains essential minerals required for plant growth. With advanced technologies like 3D printing and in-situ resource utilization (ISRU), we could convert these materials into fertile soil and essential nutrients.
### 3. Advanced Hydroponics and Aeroponics
Traditional soil-based farming might not be practical in space due to microgravity and limited resources. Enter hydroponics and aeroponics—innovative methods that use nutrient-rich water and mist to grow plants. These techniques not only save space but also drastically reduce water consumption, making them ideal for space habitats.
### 4. Genetic Engineering and Synthetic Biology
Why stop at growing Earthly crops in space when we can engineer them for better performance? Genetic engineering and synthetic biology hold the promise of developing plants that can thrive in challenging extraterrestrial conditions. Imagine crops with enhanced resistance to radiation, efficient nutrient uptake, or even the ability to produce pharmaceuticals!
## The Gravity of the Situation: Challenges in Space Agriculture
### 1. Microgravity Effects
Microgravity poses a unique challenge, affecting plant growth and physiology. Without the pull of gravity, roots don't anchor as they do on Earth, and water distribution within plants becomes erratic. Addressing these issues requires innovative solutions, such as developing growth systems that simulate gravity or genetically modifying plants to adapt better to microgravity.
### 2. Radiation Protection
Space is a harsh environment, teeming with cosmic rays and solar radiation that can damage plants and impair their growth. Developing effective radiation shields and engineering radiation-resistant plants are crucial steps in ensuring that our space crops thrive.
### 3. Limited Resources
Space missions are often constrained by the limited volume and weight that can be transported. This limitation extends to agricultural inputs like seeds, soil, water, and nutrients. Efficient recycling systems and compact, high-yield crop varieties become essential in this context.
### 4. Psychological and Social Factors
Farming in space isn't just about technology - it's also about people. The psychological well-being of astronauts can significantly benefit from interactions with plants. However, cultivating a space garden requires time, effort, and adaptation to unfamiliar farming techniques. Ensuring astronauts are not only willing but also capable of managing space agriculture is an often-overlooked challenge.
## Cultivating the Future: What Lies Ahead
### 1. Collaborative Innovation
The development of space agriculture is a multidisciplinary effort, involving botanists, engineers, astrobiologists, and even psychologists. Collaborative projects like NASA's Veggie experiment on the ISS and ESA's MELiSSA project are spearheading research in this field.

1,905,443 | Thermodynamics and Software Development: Wrangling Entropy and Order in Code | In the wild world of software development, just like in thermodynamics, entropy is always lurking.... | 0 | 2024-06-29T09:15:17 | https://dev.to/jquinten/thermodynamics-and-software-development-wrangling-entropy-and-order-in-code-4m6a | softwaredevelopment, softwareengineering, programming, development | In the wild world of software development, just like in thermodynamics, entropy is always lurking. Understanding these scientific principles can give us some insights into taming and improving our codebases.
Let’s throw on our lab coats and dive into how the laws of thermodynamics can jazz up our approach to software development! 🧪
## The First Law of Thermodynamics: Conserving Effort and Resources
The first law of thermodynamics, aka the law of energy conservation, tells us that energy can’t be created or destroyed in an isolated system—it just **changes forms**.
### Conserving Effort in Software Development
Think of energy as all the effort and resources we pour into building and keeping our code in shape.
### Managing Conservation
To make the most of our efforts, try these practices:
- Effort Redistribution: A certain amount of efforts spent on maintenance and improving remains the same. So automate those boring, repetitive tasks like testing and deployment to free up developer time for the cool, creative stuff.
- Technical Debt Management: Regularly tackle technical debt. Ignoring it might save effort now but will cost way more in the long run.
- Knowledge Sharing: Spread the wisdom across the team with code reviews, pair programming, and solid documentation. This ensures no one person is a single point of failure and keeps things running smoothly.
## The Second Law of Thermodynamics: Embracing Entropy
The second law of thermodynamics tells us that entropy (or disorder) in a system only increases over time. In simpler terms, **things naturally get messier **(sound familiar?). Plus, heat doesn’t move on its own from a cold body to a warm one.
### Entropy in Software Development
Entropy in our coding world is that creeping complexity and disorder in a codebase. As we pile on new features, fix bugs, and refactor, things tend to get more complicated. Without a plan to handle this mess, the codebase can become a nightmare to understand, maintain, and expand.
### Managing Entropy
Here’s how to keep the chaos in check:
- **Regular Refactoring**: Regularly tidy up and improve your code structure. Refactoring cuts down complexity and boosts readability, making the code easier to manage.
- **Code Reviews**: Conduct thorough code reviews to make sure new changes stick to established standards and best practices. This helps keep unnecessary complexity at bay.
- **Automated Testing**: Use automated tests to catch regressions and make sure changes don’t cause new issues. Tests act like a safety net, maintaining order in the codebase.
- **Documentation**: Keep clear and up-to-date documentation. Good docs help developers grasp the system’s design, reducing the mental load when dealing with complex code.
Given the second law of thermodynamics, you need to spend resources to fight the natural mess. If you let things slide, your software will turn into an unmanageable beast.
## The Third Law of Thermodynamics: Approaching Order
The third law of thermodynamics says that as a system’s temperature drops to absolute zero, its entropy (disorder) hits a low, **stable point**. For most systems, this means they become **super ordered**.
## Absolute Zero in Software
In our coding universe, absolute zero is like reaching **peak stability and minimal complexity**. While hitting absolute zero is impossible (this would be the equivalent of a blank HTML page), aiming for minimal entropy is a worthy goal. This means striving for simplicity, clarity, and efficiency in our code.
### Striving for Minimal Entropy
To get closer to this ideal state, try these strategies:
- **Simplicity**: Keep it simple, stupid! Simple code is easier to understand, test, and maintain.
- **Trimming excess**: If code isn’t needed anymore, chop it out. Don’t just comment it out—remove it entirely. Version control makes this easy, so aggressively cut out unused features, functions, or parameters. Unused code just adds to the mess.
- **Modularity**: Design systems to be modular, where components are loosely connected and highly cohesive. This reduces overall complexity and makes changes easier to manage.
- **Consistency**: Stick to consistent coding styles, naming conventions, and architectural patterns. Consistency cuts down the mental overhead needed to work with the codebase.
- **Continuous Improvement**: Always look for ways to improve. Regularly assess and refine your processes, tools, and techniques to strive toward minimal entropy.
## Conclusion
By understanding and applying the principles of thermodynamics to software development, we can better handle the natural complexity and entropy in our systems. Embracing practices that cut down complexity and boost order helps create more maintainable, efficient, and robust software. Just like in thermodynamics, acknowledging and managing entropy is key to achieving long-term stability and success in software development.

This topic came to life after reading “[Explaining Humans](https://www.goodreads.com/book/show/49624060-explaining-humans)” by Dr. Camilla Pang. She draws parallels between human behavior and the laws of thermodynamics. While reading it, I started seeing those connections with software development too. If you’re into (popular) science books or curious about human behavior, I highly recommend this book! | jquinten |

Today, we're going to talk about encrypting disks in GCP using the Key Management Service, or KMS, and we'll also discuss the three possible ways to encrypt them.
GCP offers robust and versatile encryption solutions. Whether you're looking to encrypt data at rest, in transit, or during processing, GCP has got you covered.
One of the tools that GCP offers for encryption is the Key Management Service, or KMS. KMS allows you to create, import, and manage cryptographic keys for your cloud services. These keys are essential for encrypting and decrypting data.
The first method is using Google-managed encryption keys. This is the default encryption provided by GCP. Here, Google automatically encrypts your data before it's written to disk.
The second method is using customer-managed encryption keys through KMS. This gives you more control over your encryption keys.
And the third method is using customer-supplied encryption keys. This is where you create and manage your own encryption keys outside of GCP.
When you create a disk, it is automatically encrypted with the first method, and if you don’t change any settings, it will always be like that. When we create a disk, the option that is activated is "Google-managed encryption key." And when the disk is created and we check inside, we see "Google-managed."
Now, to use the second method, we first need to create a ring in KMS. This ring is going to be a container for our keys, and this key could be a random one created by Google, or if we have one, we can import it. In our case, we are going to create a software key that will later be used on our disks.
When the key is created inside our ring, we can use it. To do that, when we go to create a disk, in the encryption section, we can choose our encrypted KMS key. And as before, when the disk is created, we can go inside and see how now the disk is not marked as Google-managed because we created the KMS key.
For the third option, we are going to create our own certificate, and to do that, we are going to use a Python script. The problem here is that if you lose this code and for some reason it is needed, you will lose all the information on the disk. As soon as we create the disk and choose the third option, we can paste the key, and now when we go inside the disk, we can see how it is marked as that.
I hope that you enjoy this session and don’t forget to encrypt.

1,905,439 | My AiOPS Journey | My AIOps Journey: A Comprehensive Overview I began my AIOps journey on March 29th, and I... | 0 | 2024-06-29T09:14:20 | https://dev.to/ashhadali/my-aiops-journey-40n0 | ai, aiops, devops, cybersecurity | ## **My AIOps Journey: A Comprehensive Overview**
I began my AIOps journey on March 29th, and I am excited to share what I have learned and how it can benefit you. Below, I outline the key areas of focus in AIOps and provide insights into my learning experience.
### **Core Areas of AIOps**
1. Cyber Security
2. SysOps
3. DevOps
4. Cloud Computing
5. Artificial Intelligence
### **Cyber Security**
In the realm of cyber security, I have gained hands-on experience in various domains, including web, mobile, and API penetration testing, source code review, and both static (SAST) and dynamic (DAST) application security testing. For vulnerability assessment and penetration testing, I follow the OWASP Top 10, WSTG, and MSTG guidelines and participate in bug bounties. Additionally, I use PortSwigger labs to learn more concepts and techniques. If you want to become a good pentester, follow these two resources: OWASP and PortSwigger articles and research. I already had experience in VAPT, so I covered it quickly. If you are a beginner, it might take around 2 months to understand it, but these websites will make your learning process easier.
If you don’t know how to learn about a vulnerability, here’s a method that works for me:
1. **What is XSS?**
2. **How does it work?**
3. **Where is it found?** (Parameters on a website, etc.)
4. **How to find it?**
5. **How to exploit it?**
6. **How to mitigate it?**
Learn step by step. This method applies to any bug you want to study.
From a theoretical perspective, I have studied CISSP and made some notes of important words my trainer said. Here are a few:
- Due care and due diligence
- Types of security audits
- SOC 2 reporting requirements
- The importance of defining the scope of security audits
- CIA (Confidentiality, Integrity, Availability) triad
- Compliance with local laws
- Business Continuity and Disaster Recovery (BCDR)
- Recovery Time Objective (RTO)
#### **Key Takeaways**
Here are some key terms I noted during the training that you can use during interviews:
- **Data Set:** An individual who is the subject of personal data.
- **Data Owner:** The entity responsible for the data.
- **Security as Code:** Implementing security measures as code embedded in the organization's fabric.
Additionally, I explored the Graham-Denning Security Model and preventive controls, which emphasized the gradual implementation of security measures. I also focused on top mitigation strategies, including system enumeration, entry point identification, log monitoring, account management security, backup verification, and patch management (both in-house and outsourced).
### **Practical Skills and Tools**
I have developed practical skills in Red Hat Linux, including LUN scanning, disk scanning, logical and extended partition management, backup procedures, security configurations, GREP, IP gateway configuration, process management, and command-line tools like `top`.
Many people ask how I learned such a big topic with lengthy videos. I used ChatGPT to learn it. First, I asked ChatGPT in my native language, and it answered in Roman Urdu, which made it easy for me to understand the concepts. ChatGPT provided all the commands in order and much more. From videos, I just checked how to practically apply these commands and focused on the teacher's words on using these skills in a job role. If you are a beginner, it might take some time, but it’s worth it.
In coding, I have learned Python basics, Python automation, Python Selenium, and Bash scripting. Again, I used ChatGPT for coding. ChatGPT is the best as it explains everything in deep detail and from every angle. I also watched videos to understand where and how to use these concepts in practice.
### **Cloud Computing**
I have started learning AWS Solution Architect concepts, focusing on creating VPCs, subnets, CIDR blocks, and EC2 instances.
### **DevOps**
My DevOps learning journey includes hands-on experience with Docker. I watched every video completely and did practical exercises side by side. This course is amazing for understanding containerization and exploring orchestration tools. | ashhadali |

React can also be used with JSX, which is a syntax extension to JavaScript. It combines JavaScript and HTML. React is an open source library, which means that users are allowed to work on it. React also has a small learning curve, and a large developer community, which makes it a good front-end technology for beginners.
What is Angular?
Angular is a JavaScript framework, it is open sourced. It is a single page application, that is written in TypeScript. It was built and maintained by Google Angular team. It uses HTML and CSS to build web and mobile applications.
Difference between React and Angular:
- React is JavaScript library, that is used to build interactive user interface applications. While Angular, is a JavaScript framework that is used to build complex web applications.
- React uses virtual DOM which enhances its performance. While Angular uses the real DOM.
- React feactures a unidirectional data flow. While Angular uses the two-way data binding.
- Popular apps built by React includes PayPal, IBM,Freelancer. Angular apps include Facebook, Skype, Instagram.
- React uses JSX to build fast user interfaces. While Angular uses HTML and TypeScript to build web applications.
Google trends comparison of the two apps:
Having highlighted the important differences between these two technologies, we hope to have provided you with the aid to your dilemma.
React offers a beginner the opportunity to enter the world of UI design for web applications.
I'm participating in the HNG internship programme which offers beginners into the tech industry guidance and mentorship. HNG through their online internship https://hng.tech/internship, provide a boot camp for experience for their interns.

In the pursuit of sustainable energy solutions, one intriguing option is capturing solar power from space. This concept, known as Space-Based Solar Power (SBSP), holds the promise of providing uninterrupted, clean energy to Earth. Imagine satellites equipped with massive solar panels, absorbing the sun's energy 24/7, and beaming it back down to us. This is not science fiction; it's a visionary approach that could transform our global energy landscape.
## Why Space-Based Solar Power?
### **Uninterrupted Solar Exposure**
On the surface of the Earth, solar panels are subject to weather conditions, nighttime, and seasonal changes. In contrast, space-based solar panels can capture energy continuously, without any atmospheric or diurnal interruptions. Positioned in geostationary orbit, these panels would have a line-of-sight to the sun almost all the time, enabling them to gather solar energy around the clock.
### **Greater Efficiency**
Earth's atmosphere absorbs and scatters sunlight, reducing the efficiency of ground-based solar panels. Space-based solar panels would operate in the vacuum of space, capturing more intense and unfiltered solar radiation. This could significantly increase the efficiency of electricity generation compared to terrestrial solar farms.
### **Reduction in Land Use**
SBSP systems can potentially alleviate the land use issues associated with extensive solar farms. By moving the infrastructure to space, we free up valuable real estate on Earth for other uses, be it agriculture, conservation, or urban development. This helps in balancing energy needs with ecological and societal requirements.
## How Does It Work?
### **Solar Power Satellites (SPS)**
The core of an SBSP system is the Solar Power Satellite (SPS). These satellites would be equipped with large arrays of photovoltaic panels to convert solar energy into electricity. Potentially, these satellites could stretch out kilometers in size, maximizing the surface area for energy capture.
### **Wireless Power Transmission**
Converting the captured solar power into microwave or laser beams, these satellites would then transmit the energy wirelessly to Earth. Ground-based rectenna (rectifying antennas) would receive these beams and convert them back into electricity for the grid. This innovative transmission method bypasses the need for physical conductors and helps in minimizing energy loss.
### **Energy Storage and Grid Integration**
One of the critical components of making SBSP viable is efficient energy storage and integration with existing power grids. Advanced battery systems, supercapacitors, or molten salt storage could be employed to store the energy received. Additionally, smart grid technology would ensure that this energy is distributed efficiently and balances with other renewable sources.
## Challenges and Considerations
### **Technical Hurdles**
Deploying solar power satellites on a massive scale presents several technical challenges. Launching these structures into orbit requires advancements in aerospace technology and considerable investment. Additionally, the development of efficient and safe wireless power transmission systems remains a critical hurdle.
### **Economic Viability**
The initial cost of setting up SBSP can be staggering. However, as technology matures and economies of scale kick in, these costs could decrease significantly. Innovative funding models and international collaborations could play a pivotal role in making SBSP economically viable.
### **Regulatory and Environmental Impact**
Deploying such systems also raises regulatory and environmental concerns. Space is a global commons, and the legal framework for the placement and operation of solar satellites needs to be developed. Moreover, the potential ecological impacts of energy transmission beams on atmospheric conditions and living beings require thorough investigation.
## The Future of Space-Based Solar Power
Despite the challenges, SBSP represents a bold stride toward a sustainable energy future. With continuous advancements in space technology, materials science, and renewable energy systems, we stand on the brink of a new solar era. Nations, corporations, and international bodies are beginning to seriously explore this possibility, with pilot projects and feasibility studies already underway.
In summary, space-based solar power isn't just a dream; it's a tangible and revolutionary solution that could help us transition to clean energy on a global scale. By harnessing the unending power of the sun from space, we can illuminate our world sustainably and safeguard our planet for future generations.

Many users seek email services that offer a high level of anonymity to protect their identity and sensitive information. The question arises:**[ Which email cannot](https://roadrunnermailsupport.com/)** be traced? This article delves into the concept of untraceable emails, the technologies behind them, and some of the most secure email services available today.
Understanding Traceless Email
To understand what makes an email untraceable, it is essential to comprehend the mechanisms of email tracing. Typically, email tracking involves the following elements:
IP Address: Every email sent from a device can include the IP address of the sender. This can potentially be used to trace the geographical location of the sender.
Metadata: Email metadata includes information about the sender, recipient, time sent, and the path the email took through the servers.
Email Headers: These contain routing information and can sometimes reveal the sender's IP address and the servers the email passed through.
An untraceable email service will minimize or eliminate these traceable elements.
Technologies for Untraceable Emails
Several technologies can help in making emails untraceable:
End-to-End Encryption: This ensures that the email content is only readable by the sender and the recipient. Even if the email is intercepted, it cannot be deciphered without the encryption keys.
Anonymizing Services: These services mask the sender’s IP address by routing the email through multiple servers, making it difficult to trace the origin.
Disposable Email Addresses: These are temporary email addresses that can be used for a short period and then discarded, making it difficult to trace back to the original user.
VPN and Tor: Using a Virtual Private Network (VPN) or The Onion Router (Tor) can hide the user’s IP address, adding an additional layer of anonymity.

This powerful emblem not only adds a touch of spirituality to your vehicle but also serves as a reminder of Lord Hanuman's strength, devotion, and protection. At Artarium, we offer exquisitely crafted Lord Hanuman Gada Idols designed to enhance the sanctity and aesthetic appeal of your car's interior. This article delves into the significance of Lord Hanuman and his Gada (mace), the craftsmanship behind these idols, and how they can transform your driving experience.
The Significance of Lord Hanuman and His Gada
Lord Hanuman is one of the most revered deities in Hindu mythology, known for his unwavering devotion to Lord Rama, immense strength, and unyielding courage. His Gada, a powerful mace, is a symbol of his might and authority.
Symbol of Strength and Devotion: Lord Hanuman's tales of bravery and devotion are legendary. From leaping across the ocean to Lanka to find Sita, to lifting the entire Dronagiri mountain to save Lakshmana, his feats are celebrated in the epic Ramayana. Having a Hanuman Gada Idol in your car can inspire you to overcome challenges with strength and dedication.
Protection and Blessings: Hanuman is also worshipped as a protector and guardian. His presence is believed to ward off negative energies and bring blessings of safety and well-being. Placing his idol in your car symbolizes his protection during your journeys.
Spiritual Connection: For many, the presence of a deity's idol fosters a deeper spiritual connection and provides a sense of peace. The Hanuman Gada Idol serves as a constant reminder of faith and devotion, helping you stay connected to your spiritual beliefs.
Craftsmanship and Material Quality
At Artarium, the Lord Hanuman Gada Idols are crafted with meticulous attention to detail and the highest standards of quality. Each piece is a testament to the skill and dedication of our artisans.
Material Selection: The idols are made from high-quality materials such as brass, bronze, and resin, ensuring durability and a premium finish. These materials are chosen not only for their aesthetic appeal but also for their longevity and resistance to wear and tear.
Artistic Process: The creation of each Hanuman Gada Idol involves a detailed artistic process. Our artisans start with precise sketches and models to capture the exact likeness of Lord Hanuman and his Gada. This is followed by molding, casting, and hand-finishing techniques to bring out the intricate details and expressions.
Attention to Detail: The finer details of the idol, such as Hanuman's facial expressions, the intricate designs on his Gada, and the textures of his attire, are crafted with utmost precision. This attention to detail ensures that each idol is not just a decoration, but a work of art that captures the divine essence of Lord Hanuman.
Enhancing Your Car's Interior with Hanuman Gada Idol
Adding a Lord Hanuman Gada Idol to your car dashboard can significantly enhance the interior's aesthetic and spiritual ambiance.
Visual Appeal: The idol's intricate design and high-quality finish make it a visually striking accessory. Its presence on the dashboard can elevate the overall look of your car's interior, adding a touch of elegance and sophistication.
Spiritual Ambiance: The Hanuman Gada Idol brings a sense of serenity and spiritual energy to the vehicle. This can be particularly comforting during long journeys or stressful commutes, providing a calming influence.
Personal Touch: Car interiors often reflect the owner's personality and beliefs. The Hanuman Gada Idol allows you to infuse your spiritual beliefs into your vehicle, making it a personal sanctuary.
Conversation Starter: A beautifully crafted idol on the dashboard can be a great conversation starter. Passengers and fellow car enthusiasts are likely to be intrigued by the idol's design and symbolism, leading to meaningful discussions about spirituality and culture.
Installation and Maintenance
Installing the Lord Hanuman Gada Idol on your car dashboard is a simple process, and maintaining its pristine condition requires minimal effort.
Installation: Most idols come with an adhesive base or a magnetic mount. This ensures that the idol stays securely in place even during bumpy rides. To install, clean the surface of the dashboard, remove the protective backing from the adhesive or magnet, and press the idol firmly into place.
Maintenance: Maintaining the idol is easy. Regular dusting with a soft cloth will keep it looking shiny and new. For deeper cleaning, a damp cloth or a mild metal cleaner can be used for metal idols. Avoid using harsh chemicals or abrasive materials, as these can damage the finish.
Where to Buy
The Lord Hanuman Gada Idol for car dashboards can be found at various spiritual accessory stores, online marketplaces, and specialty shops like Artarium that focus on religious décor.
Online Marketplaces: Websites like Amazon, Flipkart, and Etsy offer a wide range of dashboard idols, including the Hanuman Gada Idol. These platforms often provide customer reviews and ratings, helping you make an informed decision.
Specialty Stores: For those who prefer to see the product in person before buying, specialty stores that sell spiritual and religious accessories are a great option. These stores often have knowledgeable staff who can provide insights into the craftsmanship and quality of the pieces.
Direct from Artisans: Some of the best-quality idols come directly from artisans and small-scale manufacturers. Purchasing directly from these sources not only supports local craftsmanship but also ensures that you are getting a unique and well-made product.
Conclusion

1,905,412 | Managing Existing AWS Resources with Terraform Import | Imagine you've deployed some resources in AWS and now want to manage them using Terraform. Terraform... | 0 | 2024-06-29T08:47:36 | https://dev.to/sepiyush/managing-existing-aws-resources-with-terraform-import-dd | terraform, aws | Imagine you've deployed some resources in AWS and now want to manage them using Terraform. Terraform uses a state file to keep track of resources, which can be stored locally, in an S3 bucket, or a database. When you create a Terraform configuration and execute the plan command for the first time, Terraform identifies the configurations as new deployments. If you proceed, the apply command will error out, stating that the resources already exist.
### Understanding the Issue
This error occurs because Terraform generates and updates a state file on every deployment. During the first deployment, if there is no state file, Terraform considers the resources as newly created. However, there is a way to map the already created resources to the state file using the `terraform import` command.
### Using `terraform import`
The `terraform import` command allows you to map existing resources to the Terraform state file. Here’s how to do it:
1. **Create a Configuration**: First, create a configuration for the resource you want to manage. For example, if you want to map a DynamoDB resource that already exists in AWS, you need to add resource snippet to your configuration file like this:
```hcl
resource "aws_dynamodb_table" "your_table" {
# Configuration will be populated after import
}
```
2. **Import the Resource**: In the command line, use the `terraform import` command to map the AWS DynamoDB resource to the Terraform state file. Replace `'aws_dynamodb_table.your_table'` with your resource identifier and `'table-name-in-aws'` with the name of your DynamoDB table in AWS:
```sh
terraform import 'aws_dynamodb_table.your_table' 'table-name-in-aws'
```
### Example: Importing a DynamoDB Table
Here’s a step-by-step example of how to import a DynamoDB table into Terraform:
1. **Create Configuration**: Save the following configuration in a `.tf` file (e.g., `main.tf`):
```hcl
provider "aws" {
region = "us-west-2" # Replace with your region
}
resource "aws_dynamodb_table" "my_table" {
# The configuration will be added after import
}
```
2. **Run the Import Command**: Execute the following command in your terminal:
```sh
terraform import aws_dynamodb_table.my_table my-dynamodb-table
```
3. **Verify the Import**: After the import, check your state file to see that the DynamoDB table is now managed by Terraform. You can view the state file by running:
```sh
terraform show
```
4. **Update Configuration**: Now, update your `main.tf` file with the actual configuration of your DynamoDB table. This might involve adding attributes like hash key, read capacity, write capacity, etc.
5. **Plan and Apply**: Run the `terraform plan` command to see if your configuration matches the AWS resource. If everything looks good, you can proceed with `terraform apply` to apply any necessary changes:
```sh
terraform plan
terraform apply
```
### Finding Resource-Specific Import Documentation
One of the great features of Terraform documentation is that it provides import instructions on the same page as the resource creation documentation. For example, for DynamoDB tables, you can find detailed import instructions [here](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/dynamodb_table#import).
### Conclusion
By using the `terraform import` command, you can map existing AWS resources to the Terraform state file, allowing you to manage them seamlessly with Terraform. This process involves creating a basic configuration, importing the resource, updating the configuration, and verifying it with the `terraform plan` command. With these steps, you can efficiently bring existing resources under Terraform management. | sepiyush |
1,905,419 | Gravitational Waves The Symphony of the Cosmos | Dive into the fascinating world of gravitational waves and discover how these ripples in spacetime revolutionize our understanding of the universe. | 0 | 2024-06-29T08:46:43 | https://www.elontusk.org/blog/gravitational_waves_the_symphony_of_the_cosmos | physics, astronomy, innovation | # Gravitational Waves: The Symphony of the Cosmos
Imagine the universe as a vast, silent symphony, where the grand orchestra isn't made up of musicians but of galaxies, black holes, and neutron stars. Instead of sounds, these cosmic entities create ripples in the very fabric of space and time, known as **gravitational waves**. Let's embark on an exhilarating journey to unravel the concept of gravitational waves and explore their profound significance in our understanding of the universe.
## What Are Gravitational Waves?
Gravitational waves are disturbances in the curvature of spacetime, generated by certain gravitational interactions. Predicted by Albert Einstein in 1915 as part of his general theory of relativity, these waves propagate at the speed of light, carrying with them information about their cataclysmic origins.
### The Dance of Cosmic Giants
When massive objects like black holes or neutron stars spiral into each other, they create ripples that propagate outward from the source—much like how a stone thrown into a pond creates ripples. These ripples are gravitational waves, and they offer a new way to observe and understand the cosmos.
## Why Are Gravitational Waves Important?
### Peering into the Invisible
Traditional astronomy, relying on electromagnetic waves (like visible light, radio waves, and X-rays), limits our ability to observe many celestial phenomena. Gravitational waves, on the other hand, provide an unobstructed view into events that don't emit light, such as the collisions of black holes. This ability to observe the universe in a completely new way is revolutionary.
### Testing Einstein's Theory of General Relativity
Gravitational waves serve as an excellent testing ground for general relativity. The precise measurements of these waves allow scientists to verify the predictions of Einstein's theory under extreme conditions, further cementing or challenging our understanding of fundamental physics.
## The Landmark Detection
The first direct detection of gravitational waves occurred on September 14, 2015, by LIGO (Laser Interferometer Gravitational-Wave Observatory). This groundbreaking event, generated by the merger of two black holes about 1.3 billion light-years away, marked the dawn of a new era in astrophysics. Here’s what made it exceptional:
- **Precision**: LIGO detected distortions in spacetime smaller than one-thousandth the diameter of a proton.
- **Verification**: The signal matched the pattern predicted by general relativity for a binary black hole merger.
- **Expansion**: This discovery proved that binary black holes exist, something only theorized before.
## How Do We Detect Gravitational Waves?
### The Technologies Behind the Miracle
Gravitational wave detectors like LIGO and Virgo use laser interferometry. Here's a simplified breakdown of the process:
1. **Lasers and Mirrors**: A powerful laser beam is split into two, traveling down perpendicular arms.
2. **Interference Pattern**: The beams reflect off mirrors and recombine. If a gravitational wave passes, it distorts spacetime, altering the lengths of the arms slightly, creating a detectable shift in the interference pattern.
## The Future: Gravitational Waves Leading the Way
The detection of gravitational waves is just the beginning. Future projects, such as the proposed space-based observatory LISA (Laser Interferometer Space Antenna), aim to detect gravitational waves from even more sources, like supermassive black hole mergers and the big bang's aftermath.
### Multimessenger Astronomy
Combining gravitational wave detections with traditional electromagnetic observations—known as multimessenger astronomy—promises an unprecedented understanding of the universe. For instance, a recent joint observation of a neutron star merger (detected by both gravitational waves and gamma-rays) provided insights into the origin of heavy elements like gold and platinum.
## Conclusion
Gravitational waves have opened a new chapter in our cosmic exploration, providing us with a unique tool to decipher the enigmas of the universe. This revolutionary advancement epitomizes the blend of human ingenuity and the unyielding quest for knowledge. As we continue to listen to this silent symphony, who knows what other secrets of the cosmos will be revealed?
In the words of Carl Sagan, "Somewhere, something incredible is waiting to be known." Gravitational waves are our beacon guiding us to those incredible discoveries.

1,905,416 | Error handling in Next.js App Router | If you've been working with Next.js 14 and you've spotted the error.js file in your directory, you... | 0 | 2024-06-29T08:40:29 | https://dev.to/syketb/error-handling-in-nextjs-app-router-5b8a | nextjs, javascript, react, beginners | If you've been working with Next.js 14 and you've spotted the error.js file in your directory, you might be wondering what it's all about. Well, you're in luck! Today, we're going to break down this file and see how it helps us out.
First of all, let's understand how the error file works. The error.js file convention allows you to gracefully handle unexpected runtime errors in nested routes.
- Automatically protect each part of your route along with its nested parts using a React Error Boundary.
- Design error displays are customized for each section by organizing files in a hierarchy.
- Contain errors within specific sections while keeping the rest of your app running smoothly.
- Implement features to try fixing errors without reloading the entire page.
One of the most important things is that the error.js file should be a client-side component. There is no option to make it a server-side component, as specified in the Next.js documentation. Let's look at the code of the error.js file:
```javascript
'use client' // Error components must be Client Components
import { useEffect } from 'react'
export default function Error({
error,
reset,
}: {
error: Error & { digest?: string }
reset: () => void
}) {
useEffect(() => {
// Log the error to an error reporting service
console.error(error)
}, [error])
return (
<div>
<h2>Something went wrong!</h2>
<button
onClick={
// Attempt to recover by trying to re-render the segment
() => reset()
}
>
Try again
</button>
</div>
)
}
```
Here is an overview of how error.js file work:
error.js creates a React Error Boundary around a specific component or page.js. It uses the exported React component from error.js as a backup. If an error occurs within this boundary, it's isolated, and the backup component is shown. Despite the error, layouts above the boundary stay functional, allowing for error recovery options within the backup component.
## Recovering From Errors
If an error is temporary, retrying might fix it. Using the reset() function in an error component prompts users to try again. When reset() the Error Boundary attempts to re-render its contents. If successful, the fallback error component is replaced with the new result.
```javascript
'use client'
export default function Error({
error,
reset,
}: {
error: Error & { digest?: string }
reset: () => void
}) {
return (
<div>
<h2>Something went wrong!</h2>
<button onClick={() => reset()}>Try again</button>
</div>
)
}
```
## Nested Routes
Nested Routes in React involve rendering components in a structured hierarchy.
For instance, consider a scenario where two nested segments each contain layout.js and error.js files. This creates a hierarchy like this:
**Nested Error Component Hierarchy**
- Errors propagate upwards to the nearest parent error boundary. This means that an error.js file will manage errors for all its nested child segments.
- Adjustments to the granularity of error UI are possible by positioning error.js files at various levels within the nested route folders.
- However, an error boundary defined in an error.js file won't handle errors from a layout.js component in the same segment, as the error boundary is nested within that layout's component.
## Handling Errors in Layouts
Error boundaries defined error.js do not capture errors occurring in layout.js or template.js components within the same segment. This hierarchy is deliberate, ensuring that crucial UI elements shared among sibling routes, like navigation, remain accessible and usable during errors.
To manage errors within a particular layout or template, include an error.js file in the parent segment of that layout.
For handling errors within the root layout or template, utilize a variant named global-error.js.
**When dealing with errors in root layouts:**
- The root app/error.js boundary doesn't handle errors from root app/layout.js or app/template.js components.
- For handling errors in these root components, utilize a variant named app/global-error.js, placed in the root app directory.
- Unlike app/error.js, global-error.js wraps the entire application, replacing the root layout with its fallback component when active. Thus, global-error.js must include its own <html> and <body> tags.
- global-error.js serves as broad error handling for the entire application, less frequently triggered due to the static nature of root components. However, it's still advisable to have a root error.js file defining a fallback component within the root layout for consistent UI and branding.
```javascript
// app/global-error.tsx
'use client'
export default function GlobalError({
error,
reset,
}: {
error: Error & { digest?: string }
reset: () => void
}) {
return (
<html>
<body>
<h2>Something went wrong!</h2>
<button onClick={() => reset()}>Try again</button>
</body>
</html>
)
}
```
## Handling Server Errors
When a Server Component encounters an error, Next.js forwards an Error object (with sensitive details removed in production) to the nearest error.js file as the error prop.
To protect sensitive data, in production, only a generic message and a digest property are sent to the client. The digest is a hash of the error useful for matching with server-side logs.
In development, the Error object sent to the client includes the original error message for easier debugging.
## Conclusion
In conclusion, error files, such as error.js or global-error.js, serve as crucial components in React applications for defining error UI boundaries within route segments. They effectively catch unexpected errors, whether originating from Server Components or Client Components and display fallback UI to maintain a smooth user experience. These files offer functionalities like resetting error boundaries and ensuring error handling consistency throughout the application. Additionally, the distinction between error.js and global-error.js provides flexibility in managing errors at different levels, from specific layouts to the root application. By adhering to best practices and leveraging tools like React Developer Tools, developers can optimize error-handling mechanisms to enhance the reliability and usability of their React applications.

1,905,413 | Architectural Patterns In Mobile Development | Starting from early button laden phones developed by companies like motorola and nokia to more modern... | 0 | 2024-06-29T08:37:04 | https://dev.to/cephasarowolo/architectural-patterns-in-mobile-development-3f3b | mobile, android, ios, programming | Starting from early button laden phones developed by companies like motorola and nokia to more modern touch screen phones developed by Apple back in 2007, development on those devices always follow a architectural pattern. According to [Wikipedia](https://en.wikipedia.org/wiki/Software_architecture), software architecture has its roots in the late 1970s but it was till the early 2000s before they really started to be used. In this post, we will be going over the common architectural patterns used in mobile development, touching on their pros and cons while giving instances when each of them should be used. More specifically, we will be looking into the **Model View Controller (MVC)** Architecture, the **Model View Presenter (MVP)** Architecture and the **Model View View Model (MVVM)** Architecture.
**1. Model View Controller (MVC)**
This architecture divides an application into three interacting parts as the name implies, the Model, the View and the Controller.
**-Model:**
This holds the data to be displayed to the user. This is the part that is mostly used to interact with the database
**-View:**
This displays the data gotten from the model to the end user as the name implies.
**-Controller:**
This is what connects the model to the view. This accepts input data from the view, processes it and sends it to the model while returning the proccessed information to the view.
**Advantages of MVC architecture:**
- Very fast developement speed.
- Easy debugging and bug fixing speed as it is very easy to track down where an issue might be occuring.
- Makes it easier to make changes and update the application.
- Makes writing of tests easier as there is separation of logic.
**Disadvantages of MVC architecture:**
- It is hard to understand the MVC architecture.
- Must have strict rules on methods
**2. Model View Presenter (MVP)**
This is similar to the MVC architecture but for a simple difference, the presenter takes over a lot of the View responsibilites. Accepting of input, choosing when to display it, etc are all managed by the Presenter here. The View only function is to display that data. No logic of any sort goes on in the View layer. The **advantages** are similar to the MVC advantages.
**Disadvantages of MVP architecture:**
- More harder to learn and use than the MVC architecture
- Not suitable for small and simple apps.
**2. Model View View Model (MVVM) Architecture**
MVVM is the most used architecture in mobile developement.This is very similar to MVC and can be confused with it sometimes. The difference is the view model allows for two way coomunication between the view and the model while MVC only allows for one way communication. Also while there is always a single controller for multiple views in MVC, in MVVM, each views has its own viewmodel which exposes methods for it to communicate directly with the model. The advantages and disavantages are very similar to the MVC ones except for the caveat that its more complex to use and manage than the MVC architecture.
**Moving On**
Selecting the best architecture to use is a process of its own. This highly depends on the complexity of the project, the application functions, the organization vision and even the developer's experience level. As a beginner, all this can be overwhelming which is why HNG is providing hands on experience to bring a beginners level up to where they would be able to comfortably choose what architecture they should use.

Hello, I'm Timilehin Abegunde, an undergraduate studying agricultural Economics with a passion for tech. As a frontend developer, I recently decided to dive into the world of backend development. This transition has been both exciting and challenging, and I am thrilled to share one of the first major backend problems I faced and how I solved it.
## The Challenge
I recently encountered a challenge while trying to build a RESTful API with NodeJS for a simple to-do list application. The goal was to set up a server that could handle CRUD operations (Create, Read, Update, Delete) for my to-do list.
As a beginner, I was unfamiliar with setting up server routes and handling requests in NodeJS. Here’s how I tackled this challenge step by step.
## Step-by-Step Solution
### 1. Understanding the Problem
I needed to create a server that could handle basic CRUD operations for my to-do list application. Initially, I was confused about how to set up server routes and manage incoming requests.
### 2. Research and Resources
To get started, I turned to the NodeJS documentation, tutorials, and online forums for guidance. The NodeJS official documentation and several beginner-friendly tutorials were incredibly helpful in understanding the basics.
### 3. Setting Up the Environment
First, I installed NodeJS and npm on my machine. Then, I created a new project directory and initialized it with `npm init`. This set up the necessary project structure and `package.json` file.
### 4. Building the Server
I decided to use Express.js, a NodeJS framework, to simplify the process. I installed Express using npm and set up a basic server with the following code:
```javascript
const express = require('express');
const app = express();
const port = 3000;
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
```
### 5. Creating Routes
Next, I created routes to handle creating, reading, updating, and deleting to-do items. For example, here is the code for the 'create' route:
```javascript
app.post('/todos', (req, res) => {
// Code to add a new to-do item
});
```
### 6. Handling Data
Initially, I used an array to store to-do items. Later, I integrated MongoDB for persistent storage, which allowed me to save and retrieve to-do items from a database.
### 7. Testing and Debugging
To ensure everything was working correctly, I used Postman to send requests to my server and test the different routes. This helped me debug issues and verify that the CRUD operations were functioning as expected.
### 8. Final Thoughts
This experience taught me a lot about backend development and boosted my confidence in working with NodeJS. I learned how to set up a server, create routes, handle data, and debug issues effectively.
## Conclusion
I am excited about the journey I am about to start with the HNG Internship. This internship is an incredible opportunity to learn, grow, and connect with like-minded individuals in the tech community.

1,905,408 | Exploring the Role of Quantum Error Correction Codes in Protecting Quantum Information | Dive deep into the fascinating world of quantum error correction codes and discover how they play a pivotal role in safeguarding quantum information from the fragile nature of quantum states. | 0 | 2024-06-29T08:30:46 | https://www.elontusk.org/blog/exploring_the_role_of_quantum_error_correction_codes_in_protecting_quantum_information | quantumcomputing, errorcorrection, innovation | # Exploring the Role of Quantum Error Correction Codes in Protecting Quantum Information
## Introduction
Quantum computing holds the promise of advancing many fields, from cryptography to complex simulations. However, one of the biggest challenges facing quantum computing is the fragility of quantum information. Quantum bits, or qubits, are incredibly sensitive to external disturbances, which can result in errors and loss of information. This is where Quantum Error Correction Codes (QECC) come into play. They are essential for enabling practical quantum computation by protecting quantum information against the plethora of errors that quantum computers are susceptible to.
## The Fragility of Qubits
Unlike classical bits, which are typically either a 0 or a 1, qubits exist in a superposition of both states. This unique characteristic allows quantum computers to process vast amounts of information simultaneously. However, this also makes qubits extremely vulnerable to various types of errors, including:
- **Bit flip errors**, where the state of a qubit is flipped from 0 to 1 or vice versa.
- **Phase flip errors**, where the phase of the quantum state is altered.
- **Decoherence**, where qubits lose their quantum behavior due to interactions with their environment.
Protecting quantum information from these errors is not just a technical necessity but a fundamental requirement for realizing the profound potential of quantum technologies.
## What are Quantum Error Correction Codes (QECC)?
Quantum Error Correction Codes are strategies designed to detect and correct errors without disturbing the quantum state. The basic idea is to encode a small amount of quantum data into a larger quantum system such that any error affecting the data can be identified and rectified.
### Basic Principles of QECC
1. **Redundancy**: Similar to classical error correction, QECCs use redundancy to protect information. This often involves encoding a single logical qubit into multiple physical qubits.
2. **Entanglement**: QECC relies heavily on the principle of entanglement. By entangling multiple qubits, the state of one qubit is intrinsically linked to the state of others, enabling the detection and correction of errors.
3. **Syndrome Measurement**: This process involves measuring ancillary qubits (ancillas) without collapsing the state of the main qubits. The measurement of these ancillas reveals the nature of any error that occurred, thereby allowing for its correction.
## Types of Quantum Error Correction Codes
### Shor Code
One of the pioneering QECCs, the Shor code, encodes one logical qubit into nine physical qubits. It protects against both bit flip and phase flip errors. The effectiveness of the Shor code has paved the way for more sophisticated quantum error correction techniques.
### Steane Code
Named after its inventor, Andrew Steane, this code encodes one logical qubit into seven physical qubits. It offers protection against both bit flip and phase flip errors as well but is more efficient than the Shor code in some aspects.
### Surface Codes
Surface codes are highly promising for practical implementations due to their robustness and scalability. They arrange qubits on a 2D lattice, where each qubit interacts only with its immediate neighbors. The connectivity requirements are lower, and they are more tolerant to errors, making them ideal for real-world quantum computers.
## Implementing QECC in Quantum Computers
### Error Correction Circuits
To correct errors, quantum computers employ error correction circuits that periodically check for errors and apply necessary corrections. These circuits typically consist of **ancilla qubits**, which interact with the data qubits to diagnose errors.
### Fault Tolerant Computation
Achieving fault tolerance means ensuring that even if some components of a quantum computer fail, the overall computation still proceeds correctly. This involves incorporating error correction codes into the structure of quantum algorithms themselves, creating a resilient quantum computational process.
## Challenges and Future Directions
Although QECCs offer robust solutions for protecting quantum information, they are not without challenges:
- **Resource Intensiveness**: Implementing QECC requires a substantial number of physical qubits, which is currently a limiting factor given the nascent state of quantum hardware.
- **Error Propagation**: Introducing error correction measures can sometimes propagate errors if not carefully managed, leading to more complex error models.
- **Decoherence times**: The coherence time of qubits—how long they can maintain their state—is still limited, making continuous error correction a demanding task.
However, the relentless progress in quantum technologies promises exciting developments. Quantum error correction is a rapidly evolving field, with new codes and techniques being proposed and tested continuously.
## Conclusion
Quantum Error Correction Codes are the unsung heroes in the quest for building practical quantum computers. They transform the fragile quantum states into a robust computational framework capable of withstanding the perturbations that threaten to derail quantum computations. By embracing the power of redundancy, entanglement, and meticulous error diagnosis, QECCs are setting the stage for a future where quantum computers can tackle problems that were once considered insurmountable.
The journey towards error-resilient quantum computation is still in its early days, but the innovation and enthusiasm in the community are infectious. Armed with sophisticated quantum error correction techniques, we are not just dwelling on the possibility of quantum advantage; we are actively engineering the quantum revolution. Here's to a future where the boundaries of computation are redefined by the qubits of tomorrow!
