CLR
Published: 2024-07-02 18:54:44

Common Language Runtime(CLR) - .Net tomonidan ishlab dasturlarning jarayonini boshqaradi. Kompilyator kompilyatsiya qilingan codeni mashina kodiga o'zgartiradi (0 - 1).

CLR tomonidan taqdim etiladigan xizmatlar xotirani boshqarish, xatoliklar bilan ishlash, xavfsizlik va boshqalarni o'z ichiga oladi.

CLR .NET ning asosiy komponentidir. Bu codelarni boshqaradigan va turli xizmatlarni taqdim etish orqali ishlab chiqish jarayonini osonlashtirishga yordam beradi. Asosan, u har qanday .NET dasturlash tilidan qat'iy nazar .NET dasturlari bajarilishini boshqarish uchun javobgardir. Common Language Runtime ostida ishlaydigan code boshqariladigan code deb ataladi. Boshqacha qilib aytganda, CLR .NET uchun boshqariladigan runtime muhitini ta'minlaydi, deb ayta olamiz.
Recursion
Tags: java, programming, learning, beginners

Recursion is a technique that leads to elegant solutions to problems that are difficult to program using simple loops. Suppose you want to find all the files under a directory that contain a particular word. How do you solve this problem? There are several ways to do so. An intuitive and effective solution is to use recursion by searching the files in the subdirectories recursively.

H-trees, depicted in Figure below, are used in a very large-scale integration (VLSI) design as a clock distribution network for routing timing signals to all parts of a chip with equal propagation delays. How do you write a program to display H-trees? A good approach is to use recursion.

To use recursion is to program using _recursive methods_—that is, to use methods that invoke themselves. Recursion is a useful programming technique. In some cases, it enables you to develop a natural, straightforward, simple solution to an otherwise difficult problem.

Supercharge Your Node.js App with Blazing Fast In-Memory Caching!
Tags: webdev, javascript, node, database
Published: 2024-07-02 17:55:00



## Introduction
If you’re experiencing latency issues in your Node.js application, implementing in-memory caching can be a game-changer. This guide will walk you through how to set up in-memory caching using node-cache in an Express.js server to significantly improve your API performance.

## The Challenge
We recently saw a rapid increase in our backend project, reaching over 1000 active users in just 5 days. However, this spike led to latency issues, with API calls averaging around 200ms. Initially, we used Redis for caching, but latency remained between 180-200ms because our Redis instance and main server were both in the US-West region, while our users were primarily in India.

To address this, we implemented in-memory caching on the server, reducing latency by approximately 60%.

Here's how to implement in-memory caching using Node.js and Express.js:

**- Install the node cache package**

`npm install node-cache`



**-  Setup your Cache**

```
const NodeCache = require('node-cache');
const myCache = new NodeCache({ stdTTL: 100, checkperiod: 120 });

// stdTTL is the default time-to-live for cache entries (in seconds)
// checkperiod is the interval for automatic cache cleaning (in seconds)

```

**-  Implement in the express js server**

```
const express = require('express');
const app = express();

// Example data fetching function
async function fetchDataFromDatabase() {
    // Simulate a database call
    return { data: 'This is some data from the database.' };
}

app.get('/data', async (req, res) => {
    const cacheKey = 'myDataKey';
    const cachedData = myCache.get(cacheKey);

    if (cachedData) {
        return res.json({ source: 'cache', data: cachedData });
    }

    const data = await fetchDataFromDatabase();
    myCache.set(cacheKey, data);
    res.json({ source: 'database', data });
});

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
    console.log(`Server is running on port ${PORT}`);
});

```

**-  Manage your cache**

```
// Get cache statistics
console.log(myCache.getStats());

// Manually delete a cache entry
myCache.del('myDataKey');

// Flush the entire cache
myCache.flushAll();

```

🚀 🚀 Working with hierarchical data in .Net Core using the hierarchyid data type.(.Net Core 8) 🚀 🚀
Tags: webdev, dotnet, beginners, programming
Published: 2024-07-02 16:48:55



🚀 HierarchyId Data Type 

The hierarchyid data type was introduced with SQL Server 2008. It’s specifically designed to represent and manipulate hierarchical data. 

Hierarchical data structures contain parent-child relationships, and hierarchyid provides an efficient way to store and query such data. 

In the context of databases, both Azure SQL and SQL Server support this data type. 

🚀 Querying Hierarchical Data 

Once you’ve stored hierarchical data using hierarchyid, you can perform various queries:Finding Ancestors and Dependents: You can query for ancestors (parents) and dependents (children) of specific items. 

💡  Depth-Based Queries 

 Retrieve all items at a certain depth within the hierarchy. 

🚀 Benefits of Using HierarchyId 

 It simplifies querying hierarchical data, making it easier and faster. 

The hierarchyid type is more aligned with .NET norms than SqlHierarchyId. It’s designed to work seamlessly with Entity Framework Core (EF Core). 

hierarchyid is a valuable tool for managing hierarchical data in .NET Core applications. 🌟 If you have any specific questions or need further assistance, feel free to ask! 😊

My Journey into Mobile Development with HNG Internship.
Tags: programming, tutorial, flutter, intern
Published: 2024-07-02 16:47:38

Hi there! I'm excited to share my journey as I start the HNG Internship and dive into mobile development. Mobile apps are a big part of our lives, and making them is both fun and challenging. Let's talk about the platforms we use to build these apps and the common software architecture patterns.

**MOBILE APPS DEVELOPMENT PLATFORMS**.
1. **Native Development:**
This means building apps specifically for either Android or iOS. For Android, you use Java or Kotlin, and for iOS, you use Swift or Objective-C.
**ADVANTAGES **
i. Great Performance: Native apps run fast and smoothly.
ii. Full Access to Features: You can use all the features of the device.
**DISADVANTAGES**
i. Time-Consuming: You need to build separate apps for Android and iOS.
ii. More Maintenance: Maintaining two codebases is a lot.
2. **Cross-Platform Development:**
This means building one app that works on both Android and iOS. Tools like React Native and Flutter help with this development.
**ADVANTAGES:**
i. Saves Time: You write the code once and it works on both platforms.
ii Cheaper: It's less expensive than building two separate apps.
**DISADVANTAGES:**
 i)Slower Performance: These apps might not be as fast as native apps.
 ii) Limited Features: Some device features might not be fully available.
**Common Software Architecture Patterns**
**1. Model-View-Controller (MVC):**
This pattern divides the app into three parts: the Model (data), the View (UI), and the Controller (logic).

**ADVANTAGES:**

i. Organized Code: Easy to manage and test.
ii. Clear Structure: Each part has a specific role.
**DISADVANTAGES:**
i. Complex for Big Apps: Can get complicated.
ii. Interconnected Parts: Changes in one part can affect others.
**2. Model-View-ViewModel (MVVM):**
This is great for apps with complex user interfaces. It separates the UI from the business logic.

**ADVANTAGES:**

i. Clean Separation: Better organization and easier to update.
ii. Automatic Updates: UI updates automatically when data changes.
**DISADVANTAGES**

i. Learning Curve: Takes time to learn.
ii. More Complex: Adds some overhead to the project.
**Why I Joined the HNG Internship**
I joined the HNG Internship to learn from the best and grow my skills in mobile development. The program offers real-world projects and a chance to work with talented developers from around the world. It’s a great opportunity to improve my coding skills and build awesome apps.

Migration from NoSql to Sql , MongoDB to PostgreSql with PRISMA.
Tags: javascript, prisma, mongodb, postgres
Published: 2024-07-02 16:43:46

In my career as a backend developer, I've recently come across a big challenge, that of moving from a Nosql database to an sql database. This task turned out to be complicated, but it gave me the ability to learn more. Today I'm going to share my experience with you!

an application using mongodb to store data, but for technical and maintenance reasons we decided to switch to postgress to benefit from more complex functionalities and queries. and this in a migration without disrupting the user experience. which was a great challenge.

the first step was to plan the migration, so I started by doing a study of the data structure in mongodb to arrange and structure it well for the migration. then I made a relationship diagram adapted to postgresql. planning was the most crucial step because at the slightest error I could lose everything or misconnect the data.

Prisma became my earliest and most valuable ally in this process. Configuring prisma with postgress seemed easier than doing it with PGSL. prisma made DB management easier by providing me with tools to help me create and manipulate my data in an intuitive and visible way in a graphical interface in the browser on prisma studio.

after defending the schema and configuration in prisma, the migration was easier but more delicate. I had to export the data from my nosQL DB and import it into the sql DB. with a little patience and delicacy, I transferred all the data. once the migration was complete, we ran a series of tests to verify the presence of all the data, while optimizing the performance of the database, which was satisfactory. 

this migration has become for me the greatest technical experience I've had in my career as a backend developer. thanks to [hng](https://hng.tech/internship) for allowing me to express my knowledge and find out more about [hng](https://hng.tech/premium).

thank you for reading all the way to the end.

Svelte and React
Published: 2024-07-02 16:35:32


**Beyond Buttons: A Frontend Showdown - Svelte vs. React**

Hey there, code enthusiasts! Today, we're diving into the dynamic world of frontend development and comparing two hot technologies: Svelte and React. Both are rockstars in building user interfaces, but they take different approaches. Let's see which one shines brighter for your next project.

**Svelte: The Compiler with Superpowers**

Svelte is a rising star, taking a unique approach. Unlike React's virtual DOM, Svelte compiles your code into highly optimized vanilla JavaScript during the build phase. This eliminates the need for a virtual DOM, resulting in smaller bundle sizes and potentially faster performance.

**Why Svelte Intrigues Me**

Honestly, the idea of super-clean, compiled code is exciting! Svelte seems ideal for building performant web applications, and its reactive system feels intuitive. As I delve deeper into frontend development at HNG https://hng.tech/internship, I'm definitely eager to explore Svelte alongside React to see which one feels more natural for different project needs.

**React: The OG Component King**

React, developed by Facebook, is a heavyweight champion. It's a JavaScript library that uses a component-based architecture. Imagine building complex UIs by snapping together pre-built, reusable components – that's React's core strength. It offers a mature ecosystem, tons of libraries, and a massive community for support.

**What I Love About React**

As a proud HNG Intern yearning to refine my frontend skills https://hng.tech/premuim, React is like the perfect jungle gym. The HNG curriculum utilizes React heavily, and it's fantastic for building interactive experiences. The component structure makes code organization a breeze, and the learning curve, while present, feels manageable thanks to the extensive resources available.

Now, React isn't without its quirks. The virtual DOM (Document Object Model) manipulation can feel opaque for beginners, and setting up a React project can involve a bit of boilerplate code.

**The Verdict: It Depends!**

Both React and Svelte are fantastic tools, each with its strengths. React offers a mature ecosystem and a gentle learning curve, while Svelte boasts blazing-fast performance and a clean development experience.

The best choice depends on your project requirements. Building a complex, interactive app? React might be your champion.  Need a blazing-fast, single-page application? Svelte could be your secret weapon.

So, frontend warriors, don't be afraid to experiment!  Explore both React and Svelte (there are great jobs opportunity on the HNG platform https://hng.tech/hire, by the way!), and discover which one empowers you to build the most awesome web experiences!
