Everyone Struggles

Everyone struggles!! The earlier we normalize this, the quicker we get over things and the fact that we are perfect beings because we are **not**. We struggle over the simplest details. For example, starting this article was a big struggle for me. Why? I wanted a good and perfect intro, but the moment I let go and just began writing, it all started coming together.

Like learning how to ride a bicycle or how to swim. When we first pick this up, it seems impossible to learn, but as we progress, it is a whole lot easier than we had imagined it to be. This is so similar to my internship experience. I recall when I was given my first task, I struggled with a lot of things during the first few days, trying to figure them out myself and failing to do so. The imposter syndrome kicks in: do I deserve to be here? I am undeserving of this. But what we do not understand is that everyone goes through this, and it isn't all about you. You will realize that just a little guide from a mentor or a friend throws more light into the concept, and it becomes easier to do. This describes my first week in Ersilia. I had a lot of information to look through to successfully incorporate a model. Some of which involved going through their publication, looking at source codes, studying the packages used to build the model, and understanding Ersilia's code base. I put an expectation on myself to deliver and deliver perfectly within a short frame of time. Hence, I tried getting all the information I needed quickly. The moment, however, I let go and took each task as it came, reaching out when stuck, it all became easier. Like learning to ride a bicycle, after my first incorporation, my second and later tasks became a whole lot easier to do.

We all get the urge to deliver exceptionally well, or the nerves on the first day at a job, which makes us struggle. However, the moment we learn to normalize that you're not the first and take each stage in bits, it becomes a whole lot easier. As usual, catch me later on as I share bits of my progress during this internship. Till then, Adieus.
What is WYSIWYG?
Published: 2024-01-16 12:25:49

WYSIWYG stands for "What You See Is What You Get." It is a user interface design concept that allows users to interact with a system or software application in a way that closely resembles the final output or appearance. In a WYSIWYG system, the on-screen display during the editing or design phase should closely represent how the document or content will look when it is printed or displayed.

WYSIWYG is commonly associated with word processors, desktop publishing software, web design tools, and other applications where users create or edit documents, layouts, or content. The goal is to provide a visual representation that allows users to make real-time changes and see the immediate impact on the final output.

For example:

1. **Text Editors**: In a WYSIWYG text editor, users can format text, change fonts, adjust spacing, and apply styles directly on the screen, and the displayed text closely reflects how it will appear when printed.

2. **Web Design Tools**: WYSIWYG web design tools enable users to create web pages visually, placing elements on the page and adjusting their properties without needing to write or view the underlying HTML code.

3. **Desktop Publishing Software**: In desktop publishing applications, users can design brochures, newsletters, and other printed materials with a WYSIWYG interface, ensuring that the layout on the screen corresponds to the final printed document.

The WYSIWYG concept simplifies the user experience by providing a more intuitive and direct way to interact with content, reducing the need for users to visualize the final output separately. It has been widely adopted to enhance user productivity and make content creation more accessible to a broader audience.
Securing Your Node.js App on AWS EC2: A Guide to Nginx, Let's Encrypt, and Custom Domains
Tags: ec2, node, aws, nginx
Published: 2024-01-16 12:44:31

In today's digital landscape, security is paramount. This guide aims to walk you through the process of securing your Node.js application on an AWS EC2 instance. We'll cover configuring Nginx, obtaining a free SSL certificate from Let's Encrypt, and setting up a custom domain.


## Step 1: SSH into your EC2 instance

Login to you instance with your instance username and Key File:

```bash
ssh  -i "PATH/TO/YOUR/KEY/FILE.PEM" "USER-NAME@SERVER-IP"
```


## Step 2: Install Nginx and Certbot

If you haven't already installed Nginx, you can do so using your package manager. For example, on a Debian-based system:

```bash
sudo apt update
sudo apt install nginx certbot python3-certbot-nginx
```
(python3-certbot-nginx is an Nginx plugin for Certbot)


## Step 3: Configure Nginx for Your Node.js App

Begin by installing Nginx on your EC2 instance. You can create a dedicated Nginx configuration file tailored for your Node.js app, but I'm using the default configuration file:

```bash
sudo nano /etc/nginx/sites-available/default
```

This file directs Nginx to act as a reverse proxy, forwarding requests to your Node.js application. Remember to replace _YOUR-DOMAIN-NAME.TLD_ with your domain name in this snippet:

```nginx
server {
    listen 80;
    server_name YOUR-DOMAIN-NAME.TLD WWW.YOUR-DOMAIN-NAME.TLD;

    location / {
        proxy_pass http://127.0.0.1:PORT;
    }
}
```
Ensure your Node.js app is running on the specified port (PORT in the Nginx configuration).


## Step 4: Obtain a Free SSL Certificate with Let's Encrypt

Enhance your website's security by obtaining a free SSL certificate from Let's Encrypt. Install Certbot and run the following command:

```bash
sudo certbot --nginx -d YOUR-DOMAIN-NAME.TLD -d WWW.YOUR-DOMAIN-NAME.TLD
```

Certbot will prompt you for necessary information and automatically configure Nginx to use the SSL certificate.


## Step 5: Configure Certbot Auto-Renewal

Certificates obtained from Let's Encrypt are typically valid for 90 days. To automate the renewal process, Certbot provides a renewal script that you can set up with a cron job.

```bash
sudo certbot renew --dry-run
```

This command tests the renewal process without making any changes. If it runs without errors, you can add it to your crontab.

```bash
sudo crontab -e
```

Add the following line to run the renewal check twice a day:
```bash
0 */12 * * * /usr/bin/certbot renew --quiet
```

## Step 6: Restart Nginx
Before restarting Nginx, it's a good idea to test the configuration to catch any syntax errors:

```bash
sudo nginx -t
```

If the test is successful, restart Nginx to apply the changes restart Nginx to apply the changes:

```bash
sudo service nginx restart
```

Now, your site should be accessible using HTTPS, and the SSL certificate will automatically renew when necessary. Make sure to check your website to ensure that it's loading securely over HTTPS.

If you encounter any issues, feel free to ask in the comments for further assistance!
Understanding Django's Secure Password Encryption
Tags: django, webdev, security, discuss
Published: 2024-01-16 12:43:40

Django is a popular Python web framework that places a high priority on security. It has a strong focus on ensuring the safety of user passwords, with a robust encryption mechanism that is designed to protect sensitive user data. In this detailed analysis, we will delve into the layers of Django's encryption mechanism and highlight the key elements that make it a reliable protector of user information.

## Understanding the Foundation: PBKDF2

Django's password security is designed to protect user passwords from being compromised by malicious actors. At the core of this security system lies the PBKDF2 (Password-Based Key Derivation Function 2) algorithm, which is recognized for its resilience against brute-force attacks. PBKDF2 is a computationally intensive algorithm that makes it difficult for any malicious actor to crack hashed passwords. By using this algorithm, Django ensures that user passwords are stored in a secure and protected manner, making it a reliable and trustworthy platform for users to store their sensitive data.

## Salting for Unpredictability

Django introduces the concept of salting to enhance the security of user passwords against attacks. A random and unique salt is generated for each user. This salt is combined with the user's password before hashing, which results in distinct hashed passwords even if two users share the same password. This unique salt ensures that each user's password is protected and difficult to crack by attackers.

## Iterations: Striking the Right Balance

PBKDF2 is a widely used algorithm for password hashing. Its strength depends on the number of iterations, which can be configured based on the required level of security. While higher iterations result in stronger security, they also slow down the hashing process. Django, a popular web framework, uses an optimal number of iterations to balance security and performance. This ensures that user experience is not compromised while keeping the system robust and secure.

## The Anatomy of Stored Passwords

Django saves passwords in a meticulous format in the database, which includes essential information such as the algorithm used, the number of iterations, the salt, and, of course, the hashed password.

For example,
pbkdf2_sha256$150000$AbCdEfGhIjKl$AbCdEfGhIjKlAbCdEfGhIjKlAbCdEfGhIjKlAbCdEfGhIjKl

Django has a standardized structure that helps to efficiently authenticate passwords during the login process.

## Django's Fortification

Django's password encryption approach shows the framework's commitment to user security using PBKDF2, salting, and optimal iterations for defense against unauthorized access.

The complicated process of cryptographic elements guarantees that Django stays a reliable protector, capable of securing user data despite any emerging security threats. As you venture into the world of Django development, you can be confident that your users' passwords are protected by a sturdy and sophisticated system.

🚀Cardano’s Ecosystem and the Rise of DEX Volume: A Glimpse into ADA’s Performance

Increase in DEX Volume

There appears to be an increase in demand within the Cardano ecosystem. Indicating this increased demand, a noticeable rise in DEX popularity was observed. More than 10.5 million ADA in volume increase was observed at MiniSwap, one of the most popular DEXs in the Cardano ecosystem.


This increase in DEX volumes reflects a positive outlook specific to Cardano, mirroring increased activity and participation in the ecosystem. In addition, there are some obstacles for Cardano in the DeFi sector as well.

Has the Stablecoin Era Begun?

The delay in the launch process of the USDM stablecoin initially had a negative impact on Cardano and the sensitivity around the DeFi sector.

However, with the re-announced launch date, the introduction of a Cardano-specific stablecoin named USDM could signify accelerated development in the DeFi environment of the Cardano protocol.

Furthermore, a new discussion has recently emerged. The debate brings with it question marks regarding the potential implementation of USDC on Cardano. Such a development could contribute significantly to Cardano’s growth and adoption, as well as increase its appeal and attractiveness.

Despite these developments, according to data provided by Artemis, a decline in stablecoin growth within the Cardano protocol was observed. The speculated launch date of USDM and the potential integration of USDC could take Cardano to a different position in the future.

As of the time of writing, ADA is trading at $0.53776, experiencing a relatively small decrease of 1.26% in the last 24 hours. ADA’s 24-hour trading volume also decreased by 17%, staying below $300 million. In addition, the overall volume decline has not gone unnoticed by investors, falling below $19 billion.

PEPE Price Bounces but Trend Remains Uncertain – What’s Next?

PEPE Returns to Support After Breakout

The PEPE price had fallen under a descending resistance trend line since May 2023. The decrease culminated with a low in September. 

Then, PEPE began an upward movement that is still ongoing. After the fourth failed breakout attempt (red icon) in November, it successfully broke out the next month.

After peaking on December 9, PEPE started to fall. It returned to the descending resistance trend line, validating it as support on January 8 (green icon) and bouncing.

Traders utilize the RSI as a momentum indicator to assess whether a market is overbought or oversold and whether to accumulate or sell an asset.

If the RSI reading is above 50 and the trend is upward, bulls still have an advantage, but if the reading is below 50, the opposite is true. The daily RSI does not help determine the trend’s direction since the indicator is exactly at 50.

Similarly to the daily time frame, the six-hour one shows signs of a potential bottom. This is because of the wave count and the price action.  Technical analysts utilize the Elliott Wave theory to ascertain the trend’s direction by studying recurring long-term price patterns and investor psychology.

The most likely count suggests that PEPE has completed a five-wave upward movement (black) and is now correcting. The correction has been contained inside a descending parallel channel, which is common.

While this is not confirmed, the correction may have ended on January 8 since the PEPE price bounced at the channel’s support trend line and the 0.618 Fib retracement support level (green). 

A breakout from the descending parallel channel will confirm the bullish outlook. If both upward movements have the same length, an 80% PEPE price increase to the next resistance at $0.0000022 is foreseeable.

What is Miltitenancy in Software Architecture?
Published: 2024-01-16 12:07:29

Multitenancy is a software architecture or model where a single instance of a software application serves multiple tenants, or customers. In a multitenant system, each tenant's data, configurations, and instances of the application are logically isolated from one another, even though they may share the same underlying infrastructure and codebase.

Here are some key characteristics of multitenancy:

1. **Isolation**: Tenants are isolated from each other to ensure that one tenant's data and configurations are not accessible or visible to another tenant.

2. **Shared Resources**: Despite the isolation, multitenant systems typically share common resources such as the application code, databases, and infrastructure. This sharing helps in efficient resource utilization.

3. **Customization**: Multitenant applications often allow each tenant to customize certain aspects of the application, such as branding, configurations, and workflows, to meet their specific requirements.

4. **Scalability**: Multitenancy can provide scalability benefits as resources are shared among multiple tenants, allowing for more efficient use of hardware and infrastructure.

5. **Cost-Efficiency**: By sharing resources and infrastructure, multitenancy can be a cost-effective solution, especially for Software as a Service (SaaS) providers, as they can serve multiple customers with a single application instance.

Multitenancy is commonly used in cloud-based applications, where a provider serves multiple customers over the internet. It is prevalent in SaaS applications, where a single software instance is used by multiple organizations or users. Examples include customer relationship management (CRM) systems, enterprise resource planning (ERP) systems, and collaboration platforms.
