A difficult backend problem I had to solve
Tags: hng, backend, database, node
Published: 2024-07-01 11:55:55


Hey everyone! I recently faced a challenging backend problem while working on a project for my FreeCodeCamp certification. I want to share how I tackled it and why I'm excited about joining the HNG Internship.

#### The Challenge: Associating Exercises with Users

I was building an API that lets users create accounts, add exercises, and view their exercise logs. The tricky part was ensuring each exercise was correctly linked to the right user without creating duplicate data.

**The Solution**

**1. Designing the Database Schema**

I used MongoDB with Mongoose, creating separate schemas for users and exercises. The exercise schema included a reference to the user's ID, establishing a relationship between them.

```javascript
const userSchema = new mongoose.Schema({
  username: { type: String, required: true, unique: true }
});

const exerciseSchema = new mongoose.Schema({
  userId: { type: mongoose.Schema.Types.ObjectId, ref: 'User', required: true },
  description: { type: String, required: true },
  duration: { type: Number, required: true },
  date: { type: Date, required: true }
});
```

**2. Implementing the Endpoint**

Next, I created an endpoint to add exercises. It checked if the user existed, then added the exercise, linking it to the user.

```javascript
app.post('/api/users/:_id/exercises', (req, res) => {
  const userId = req.params._id;
  const { description, duration, date } = req.body;
  const exerciseDate = date ? new Date(date) : new Date();

  User.findById(userId, (err, user) => {
    if (err || !user) {
      return res.status(404).json({ error: 'User not found' });
    }

    const newExercise = new Exercise({
      userId: user._id,
      description,
      duration,
      date: exerciseDate
    });

    newExercise.save((err, exercise) => {
      if (err) {
        return res.status(500).json({ error: 'Failed to add exercise' });
      }

      res.json({
        username: user.username,
        description: exercise.description,
        duration: exercise.duration,
        date: exercise.date.toDateString(),
        _id: user._id
      });
    });
  });
});
```

#### Reflecting on the Experience

This project taught me a lot about managing database relationships and handling asynchronous operations in NodeJS. It was a challenging but rewarding experience that boosted my confidence as a backend developer.

#### Joining the HNG Internship

I’m super excited about the HNG Internship. It’s a fantastic opportunity to work on real-world projects, learn from experienced developers, and improve my skills.

The Decentralized Revolution: The Story of BitPower
In an era full of change and opportunity, BitPower stands out. As a fully decentralized platform, BitPower symbolizes a revolution in the financial world, not only changing the way money flows, but also giving ordinary people around the world the opportunity to control their own economic destiny.

The core of BitPower lies in its decentralized concept. This means that there is no single power center, no controller that can be manipulated. All transactions are conducted peer-to-peer, from one personal wallet to another. Every transaction on the platform is recorded on the blockchain, transparent and tamper-proof, ensuring fairness and security for all participants.

The decentralized design makes BitPower impossible to tamper with, and even its founders and developers cannot change the rules of the system. Since the deployment of the smart contract, BitPower has been running independently, and the rules and mechanisms will never change. This design not only increases the security of the platform, but also protects the interests of every user.

BitPower's revenue structure is also one of the core of its appeal. By providing liquidity, users can get considerable returns in a short period of time. For example, a user who provides 10,000 USDT liquidity can get 10,040 USDT after one day, and 10,400 USDT after seven days. This high-yield model makes BitPower the preferred platform for many investors.

In addition, BitPower's sharing reward structure further encourages user participation and promotion. Users can not only earn income from their own investments, but also get additional sharing rewards by inviting new users. Specifically, for every additional 100 USDT in circulation, users can get more levels of sharing rewards, up to 17 levels. This sharing reward mechanism not only promotes the expansion of the platform, but also allows more people to enjoy the dividends of decentralized finance.

In the BitPower ecosystem, all operations are automated. Smart contracts are automatically executed according to preset rules without human intervention. After each order expires, the proceeds are automatically returned to the initiator's wallet. This automated design not only improves efficiency, but also ensures the safety of each user's funds.

In general, BitPower represents a revolutionary advancement in the financial field. Its decentralized design, transparent trading mechanism, high-yield returns and fair sharing rewards make it not only an investment platform, but also a force that changes the global financial landscape. On this platform, anyone can earn income through their own efforts, break the cycle of poverty and achieve financial independence.

In this era full of challenges and opportunities, BitPower is undoubtedly the best choice for everyone who pursues financial freedom. The decentralized future has arrived, and BitPower is at the forefront of this revolution.

Text I/O vs. Binary I/O
Tags: java, programming, learning, beginners
Published: 2024-07-01 11:34:53

Binary I/O does not involve encoding or decoding and thus is more efficient than text I/O. Computers do not differentiate between binary files and text files. All files are stored in binary format, and thus all files are essentially binary files. Text I/O is built upon binary I/O to provide a level of abstraction for character encoding and decoding, as shown in Figure below (a). Encoding and decoding are automatically performed for text I/O. The JVM converts Unicode to a file-specific encoding when writing a character, and it converts a file-specific encoding to Unicode when reading a character. For example, suppose you write the string **"199"** using text I/O to a file, each character is written to the file. Since the Unicode for character **1** is **0x0031**, the Unicode **0x0031** is converted to a code that depends on the encoding scheme for the file. (Note that the prefix **0x** denotes a hex number.) In the United States, the default encoding for text files on Windows is ASCII. The ASCII code for character **1** is **49** (**0x31** in hex) and for character **9** is **57** (**0x39** in hex). Thus, to write the characters **199**, three bytes—**0x31**, **0x39**, and **0x39**—are sent to the output, as shown in Figure below (a).

Binary I/O does not require conversions. If you write a numeric value to a file using binary I/O, the exact value in the memory is copied into the file. For example, a byte-type value **199** is represented as **0xC7** (199 = 12 * 16^1 + 7) in the memory and appears exactly as **0xC7** in the file, as shown in Figure below (b). When you read a byte using binary I/O, one byte value is read from the input.

In general, you should use text input to read a file created by a text editor or a text output program, and use binary input to read a file created by a Java binary output program.

Binary I/O is more efficient than text I/O, because binary I/O does not require encoding and decoding. Binary files are independent of the encoding scheme on the host machine and thus are portable. Java programs on any machine can read a binary file created by a Java program. This is why Java class files are binary files. Java class files can run on a JVM on any machine.

Day 24 of 30 of JavaScript
Tags: webdev, javascript, beginners, tutorial
Published: 2024-07-01 11:33:05

Hey reader👋 Hope you are doing well😊
In the last post we have talked about Promises. In this post we are going to discuss about Async/Await.
So let's get started🔥

## Async/Await

Async/Await are powerful keywords in JavaScript used to handle Asynchronous operations with promises. They became feature of JavaScript with the release of ES8(ES2017). It is built on top of promises, and you can see it as an alternative syntax to promises.

**Async Keyword**

async is a JavaScript keyword used to create a function. The function created using async keyword will always return a promise. 
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pvfon0aqqpbdzi264v08.png)
So here we have created an arrow function using async keyword now we know that async returns a promise if the promise is resolved then data is printed.

**Await Keyword**

To use the await keyword, place it before a promise. It is an indicator for the async function to pause execution until that promise is settled.
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/uz49mcix1jr6y0666k8r.png)
So here our `timerFunction` returns a new promise that is resolved after 3 seconds. The `asyncFunction` uses the `await` keyword to wait for the promise returned by `timerPromise` to resolve. The `await` keyword pauses the execution of `asyncFunc` until the promise resolves. Once the promise resolves (after 3 seconds), the resolved value ("promise finished!") is assigned to the `result` variable.
Now here you can see that `await` makes sure that either the promise is resolved or rejected. Is it not similar to `.then()`.
Await is similar to the `.then()` method.

> The async keyword transforms a regular JavaScript function into an asynchronous function, causing it to return a Promise.
> The await keyword is used inside an async function to pause its execution and wait for a Promise to resolve before continuing.
As we can do chaining of `.then()` method with Promise. We can also do same using `await`.
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4jjzwatvvq5tu3oiycy1.png)

## Advantages of Async/Await

- Async and Await allow asynchronous code to be written in a synchronous style, making it easier to read and understand.

- Using try/catch blocks with async/await makes error handling straightforward.

-  Async and Await help in avoiding nested callbacks and complex promise chains.

- Debugging async/await code is more intuitive as it behaves like synchronous code.

I hope you have understood this blog well. In the next blog we are going to study about Event Loop which are very fundamental concept of Asynchronous Programming. Till then stay connected and don't forget to follow me.
Thankyou 🩵
