Why isn't the enrollment API working in my code?
Tags: javascript, api
Published: 2024-05-14 11:38:27

 In our staff training course, a new user can create a sandbox for themselves. I'm using the Brightspace (D2L) Whoami, Enrollment, and Create Course APIs. While Whoami and Create Course are working as
expected, the Enrollment API is not. I'm utilising the Enrollment API to search for a sandbox if it's already created and to avoid duplication.
Do you have any advice? Please see the part of the code below.

// Define the base URL for the Brightspace API endpoint for enrollments
    const baseURL = `https://example.com/d2l/api/lp/1.44/enrollments/myenrollments/`;

    // Define the URL for fetching enrollments with the bookmark parameter
    let enrollmentsURL = `${baseURL}?bookmark=6606`;

    // Array to store all enrollments
    let allEnrollments = [];

    // Fetch all pages of enrollments
    while (enrollmentsURL) {
      const enrollmentsResponse = await fetch(enrollmentsURL);
      const enrollmentsData = await enrollmentsResponse.json(); // Define enrollmentsData here

      // Add fetched enrollments to the array
      allEnrollments = allEnrollments.concat(enrollmentsData.Items);

      // Check if there are more pages
      if (enrollmentsData.PagingData && enrollmentsData.PagingData.bookmark) {
        enrollmentsURL = `${baseURL}?bookmark=${enrollmentsData.PagingData.bookmark}`;
      } else {
        enrollmentsURL = null;
      }
    }
// Check if the course already exists in the user's enrollments
    const courseExists = allEnrollments.some(enrollment => enrollment && enrollment.CourseName === uniqueName);

    if (courseExists) {
      // Display message if the course already exists
      document.getElementById("message").textContent = `Course "${uniqueName}" already exists in your enrollment.`;
      return; // Exit function if course already exists
    }
Beginner's First Tech Project: Avoiding Mistakes and Achieving Success
Published: 2024-05-14 11:32:27

Are you a budding tech enthusiast striving to embark on your first major project? Allow me to share insights and mistakes my small team and I made when we tried to develop a social media web app; that focuses on mental health up keep; as our first ever real tech project under a deadline.

Simply put, our initial missteps were evident. The lack of comprehensive planning led us down a path of uncertainty and constant alterations. As a team of learners, our decision-making process was often disturbed with constant revisions either because of time or our lack of knowledge with a certain technology, resulting in us deploying a more simplified **Minimal Viable Product** (MVP) than envisioned.

**The Mistakes Made:**

Our journey was filled with challenges, notably stemming from poor planning, limited time and limited knowledge. when we were writing the website requirements and initial documentation, we had no idea how big the project we planned out actually was as it couldn’t be completed within the timeframe. The problem was that our proposed MVP was **not** an MVP!!! So because the realization came mid-development, we found ourselves constantly refactoring code and revisiting the documentation we wrote before coding which was a big hit to our pace coupled with the fact that we also had to learn new technologies on the fly. All that slowed down our pace and wasted a part of the given timeframe for the project.

**So What Should you do to Avoid This Setback?**

**Plan**, it sounds so simple but should be done properly. You should always settle on a small MVP before reaching for the stars. **Thoroughly define** what features you need for the MVP, how you are going to implement them and whatever technology you would like to use.
Know your short comings, especially when there’s a deadline to meet. As a beginner in tech you should always step back and look at yourself to see if your skills are enough to tackle your project, if not i advise dividing your project into small bits so you can learn and develop on the fly. If you are working on a team, set roles and responsibilities of each member based on your strengths and use project management tools like [trello](https://trello.com/) to streamline and enhance team communication and workflow.
These two points alone should be helpful enough to any beginner techies out there.

The essence of meticulous planning, the efficacy of starting small with an MVP, and the paramount role of communication within team projects. I urge you to take note of these lessons and learn from them for your own tech ventures, be it solo or collaborative and let these insights propel you towards excellence in your tech odyssey.

What is the requirement of Proof-of-Less-Work?
Tags: cryptocurrency, asic, bitcoin, ethereum
Published: 2024-05-14 11:30:38

**[Proof of Work](https://asicmarketplace.com/blog/what-is-proof-of-less-work/)** has been used in many fields for more than a decade. It's a consensus algorithm that is highly reliable and has been tested for years. Today, energy consumption has become a top priority, causing energy and environmental concerns. It is clear that Proof of Work needs to be improved.

Proof of Less Work was created to reduce the energy consumption of traditional Proof of Work without compromising decentralization. PoLW represents the first type of cost. This is the energy costs, which are external expenses that must be paid in real life and not on blockchain.

Second, coin burning is also known as internal burn since it occurs within the blockchain. If you add up both costs and compare them with PoW, the cost of an attack on PoLW is the same.
Object Oriented Programming in Financial System
Published: 2024-05-14 11:11:29

It is a programming concept based on objects having data and methods defined in the class to which it belongs.

Then Concept Include: Encapsulation, Inheritance, Abstraction and Polymorphism.

### **Encapsulation**: 
It is a mechanism of wrapping the variables/data  and methods operate on the variables/data together as a single unit.

Example: 

- I have Spring boot application add data into data base and I’m using Object Relational Mapping (*ORM*), so I will define DAO - Data Access Object class to interact with data base table customerAccounts, this call will include private variables and public setters and getters.

### **Inheritance**: 
It is the mechanism in java by which one class is allowed to inherit the features(fields and methods) of another class.

Example: 

- The **`Account`** class serves as the base class, containing common functionalities such as deposit, withdraw and getBalance.
- The **`SavingsAccount`** class adds a **`calculateInterest`** method to calculate interest specific to savings accounts, while the **`CheckingAccount`** class adds a **`processCheck`** method to handle check processing specific to checking accounts.
- Through inheritance, the code is more organized, and common functionalities are centralized in the base class, reducing code duplication and promoting reusability.

Overriding:

- The **`Account`** class defines common functionality for all types of accounts, including deposit and withdraw methods.
- The **`SavingsAccount`** and **`CheckingAccount`** classes extend the **`Account`** class and override withdraw methods as need to calculate different fees for each account type.

### **Abstraction** 
Allows to generalize functionality of classes without providing implementation details.

Example (Interface): 

- I have **customerService** interface that contracts that define a set of methods that a class must implement. then I have **customerServiceImp** class which implements all interface methods and give their implementation.

Example (Abstract): 

- For banking system we have a Accounts abstract class which has abstract methods like (withdraw & deposit) methods and other non abstract methods (getBalance).
- We extend Accounts abstract class it’s provide different implementation for abstract methods and inherent non abstract methods (getBalance).

### **Polymorphism**: 
It means many forms, and we achieve this by Overloading (compile) and Overriding (runtime).

Example (Overloading): 

- In banking system we have**`Transaction`** class contains multiple overloaded**`transfer()`** methods, each accepting different parameters to handle different types of transactions transfer.

Example (Overriding):

- The **`Account`** class defines common functionality for all types of accounts, including deposit and withdraw methods.
- The **`SavingsAccount`** and **`CheckingAccount`** classes extend the **`Account`** class and override withdraw methods as need to calculate different fees for each account type.
Installing WireGuard VPN on Ubuntu 22.04
Published: 2024-05-14 11:23:41

Installing WireGuard VPN on Ubuntu 22.04 is relatively straightforward. Here's a step-by-step guide:

1. **Update Package List**: First, ensure that your package list is up to date by running:

    ```bash
    sudo apt update
    ```

2. **Install WireGuard**: WireGuard is available in the official Ubuntu repositories, so you can install it using `apt`:

    ```bash
    sudo apt install wireguard
    ```

3. **Generate Keys**: Generate public and private keys for the server and client. You can do this by using the `wg` command, which is part of the WireGuard package you just installed. Replace `<interface-name>` with the name of your WireGuard interface (e.g., `wg0`):

    ```bash
    umask 077
    wg genkey | tee privatekey | wg pubkey > publickey
    ```

    This will generate `privatekey` and `publickey` files. You'll need to do this for both the server and client.

4. **Configure WireGuard**: Now, you'll need to create configuration files for both the server and the client.

    For the server (`/etc/wireguard/wg0.conf`):

    ```plaintext
    [Interface]
    Address = 10.0.0.1/24
    PrivateKey = <server-private-key>
    ListenPort = 51820

    [Peer]
    PublicKey = <client-public-key>
    AllowedIPs = 10.0.0.2/32
    ```

    For the client (`client.conf`):

    ```plaintext
    [Interface]
    Address = 10.0.0.2/24
    PrivateKey = <client-private-key>

    [Peer]
    PublicKey = <server-public-key>
    Endpoint = <server-ip>:51820
    AllowedIPs = 0.0.0.0/0
    ```

    Replace `<server-private-key>`, `<client-private-key>`, `<server-public-key>`, and `<client-public-key>` with the respective private and public keys you generated earlier. Replace `<server-ip>` with the IP address of your WireGuard server.

5. **Start WireGuard**: After configuring both the server and client, you can start the WireGuard service on the server:

    ```bash
    sudo systemctl enable --now wg-quick@wg0
    ```

    Replace `wg0` with the name of your WireGuard interface if it's different.

6. **Start WireGuard on the Client**: Copy the `client.conf` file to your client machine and start the WireGuard service:

    ```bash
    sudo wg-quick up client.conf
    ```

    This command will start the WireGuard service using the configuration specified in `client.conf`.

That's it! You should now have WireGuard VPN set up between your server and client. Remember to configure your firewall settings to allow traffic on the WireGuard port (UDP 51820) if you haven't already done so.

Deployment strategies: Canary or Blue-Green?
Tags: webdev, javascript, programming, devops
Published: 2024-05-14 11:19:00

Quick question for you: when updating our app, should we go with blue-green deployments or canary releases? Here’s a rundown to help us decide.

Blue-green deployments mean maintaining two identical production environments. One is active, and the other is a clone where we deploy the new version. If the new version is stable, we switch traffic to it. If issues arise, we can quickly revert to the old environment.

Canary releases, on the other hand, involve gradually rolling out the change to a small percentage of users first, monitoring the performance and stability, and then slowly increasing the rollout percentage as confidence in the release builds.

Both strategies aim to minimize downtime and risk during updates. The choice depends on whether we want the safety net of an immediate rollback (blue-green) or the gradual exposure and risk mitigation of a canary release.

What do you think? Should we go for quick switches or gradual rollouts for our next update?
Every millisecond matters in Javascript

Published: 2024-05-14 11:05:51

> Premature optimization is the root of all evil -- Donald Knuth

In light of modern trends of increasing complexity of modern JS frameworks, high end developer hardware and the premature optimization mantra we ended up with some performance problems with modern web and especially modern mobile web (deserves a separate article). 

Probably you can't comfortably use modern web sites on a 5 year old mid/low budget device, at least the most people don't expect to upgrade their PCs used just for web surfing every year. I've ended up buying a high end android phone just to use social sites comfortably. 

One could tell that a user couldn't tell a difference between 1 and 5 ms, but given the fact we could have hundreds of operations on page or data loading, all these small overheads lead to a noticeable performance hit and poor user experience.

So I'd say that every millisecond matters in Javascript. Premature optimization is bad when you spend significant amount of time on a code piece that is thrown away later due refactoring. But what if you could write highly performant Javascript code from the beginning? You just don't need to optimize later and the whole premature optimization thing isn't relevant anymore. So learn how to write fast Javascript, I believe it will pay off.

In the next posts that would form a series I will be collecting tips how to write fast Javascript.

Optimizing HTML Code for Glass-Wearers: Accessibility Tips for Web Developers
Published: 2024-05-14 10:55:40

As a web developer, optimizing HTML code for **_[glasses](https://www.efeglasses.com/)_** can greatly improve accessibility. Here are some tips to consider based on the available documents:

1. Use Clear and Legible Fonts:

Ensure that the fonts used on your website are clear and easy to read. Consider using sans-serif fonts like Arial or Verdana, as they are generally easier to read on screens. Additionally, make sure the font size is large enough to accommodate those who may have difficulty reading smaller text.

2. Implement Responsive Design:

Responsive design is crucial for glass-wearers, as it allows your website to adapt to different screen sizes. This ensures that the content remains easily readable and accessible, regardless of the device being used. Test your website on different screen sizes and adjust the layout as needed.

3. Provide Sufficient Color Contrast:

Ensure that there is enough contrast between the text and background colors on your website. This helps individuals with visual impairments, including glass-wearers, to read the content more easily. Use tools like color contrast checkers to ensure that your color combinations meet accessibility guidelines.

4. Include Alt Text for Images:

When adding images to your website, be sure to include descriptive alt text. This provides a text alternative for individuals who use screen readers or have images disabled. It allows them to understand and navigate the content more effectively.

5. Structure Content with Headings:

Use HTML heading tags (h1, h2, etc.) to structure your content. This helps individuals using screen readers to navigate through the page more efficiently. It also improves the overall readability and organization of your content.

6. Enable Keyboard Navigation:

Ensure that all interactive elements on your website, such as buttons and links, can be accessed and activated using a keyboard. This is important for individuals who may have difficulty using a mouse or touchscreen. Test your website's keyboard accessibility to ensure a seamless user experience.

7. Test with Assistive Technologies:

To truly optimize your HTML code for glass-wearers and improve accessibility, it's important to test your website with assistive technologies, such as screen readers or magnification tools. This allows you to identify any potential issues and make necessary adjustments for a more inclusive user experience.

By implementing these accessibility tips, you can optimize your HTML code to better serve glass-wearers and improve overall accessibility for all users. Remember to constantly test and refine your website to ensure it remains accessible and user-friendly for everyone.

Mastering Callbacks in JavaScript 💻🔥
Tags: callback, javascript, asynchronous, webdev
Published: 2024-05-14 10:31:38


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/w7xtr5bjiywh7oz5ovzf.png)

**Basics of Callbacks 😊**

Callbacks are functions passed as arguments to other functions, enabling the invocation of code at a specific point during or after an asynchronous operation. They serve as a mechanism for handling the results or errors of these operations.

**Let's explore a simple example to understand how callbacks work in practice**

```js
function fetchData(callback) {
  setTimeout(() => {
    const data = 'Hello, World!';
    callback(data);
  }, 2000);
}

function processData(data) {
  console.log(`Received data: ${data}`);
}
fetchData(processData);

```
In this example, the fetchData function simulates an asynchronous operation by using setTimeout. It accepts a callback function and invokes it with the retrieved data. The processData function serves as the callback, receiving and processing the data once it's available.

**Advanced Callback Patterns**

```js
function fetchData(callback, errorCallback) {
  setTimeout(() => {
    const error = false;
    if (error) {
      errorCallback(new Error('Data retrieval failed!'));
    } else {
      const data = 'Hello, World!';
      callback(data);
    }
  }, 2000);
}

function processData(data) {
  console.log(`Received data: ${data}`);
}

function handleFetchError(error) {
  console.error(`Error: ${error.message}`);
}

fetchData(processData, handleFetchError);

```
In this revised example, the fetchData function introduces an errorCallback parameter. If an error occurs during the asynchronous operation, the errorCallback is invoked with an Error object. The handleFetchError function acts as the error callback, providing a standardized approach to handle errors.

In Conclusion, Callbacks are the backbone of JavaScript's asynchronous programming paradigm. By mastering callbacks, you empower yourself to handle complex asynchronous scenarios efficiently. In this post, we covered the basics of callbacks, advanced patterns like error handling, and techniques to avoid callback hell. Armed with this knowledge, you'll be well-equipped to write robust and scalable JavaScript code. Embrace the power of callbacks and unlock the true potential of JavaScript!
