In the world of software development, unique identifiers (IDs) play a crucial role in managing and accessing data. While Django models typically use auto-incrementing integer IDs by default, this approach can pose security and privacy concerns. Here's where [Universally Unique Identifiers (UUIDs)](https://en.wikipedia.org/wiki/Universally_unique_identifier) come to the rescue, offering a more robust and secure alternative.

## The Problem

Sequential IDs, like 1, 2, 3, are easily guessable. Publicly exposing sequential IDs in URLs can be problematic. This allows malicious actors to potentially manipulate URLs and potentially access unauthorized resources. If you expose "/resource/1" and "/resource/2," users might guess "/resource/3". This can lead to unexpected behavior and potential security vulnerabilities if, for instance, the resource access check is for some reason omitted.

## A mitigation solution

UUIDs are 128-bit random numbers represented as strings like "34f212e4-212f-47b6-b6b6-34f212e4212e." They offer several key advantages:

- **Uniqueness:** The sheer randomness of UUIDs makes them incredibly unlikely to collide, even across multiple servers or databases. This eliminates predictability and guessability, significantly enhancing security.
- **Anonymity:** UUIDs don't reveal any inherent order or information about the data they identify. This protects sensitive information and enhances user privacy.
- **Scalability:** UUIDs are efficient and scalable, even for large datasets. They don't suffer from performance issues associated with auto-incrementing integers, especially in distributed systems.

Django provides the `UUIDField` to seamlessly integrate UUIDs into your models. Here's how:

```
from django.db import models
import uuid

class MyModel(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4)
    # ... other fields

```

Moving from sequential IDs to UUIDs in Django is a straightforward yet impactful security and privacy upgrade. By leveraging the inherent randomness and anonymity of UUIDs, you can significantly strengthen your application's defenses while improving scalability and flexibility with one simple small change.

Why use GraphQL
Tags: webdev, javascript, beginners, programming
Published: 2024-02-23 13:48:24

#GraphQL is a powerful and flexible technology that addresses several challenges associated with traditional REST APIs.  



**Why use GraphQL:**



1. **Efficient Data Retrieval:**

  - One of the main reasons to use GraphQL is its ability to allow clients to request only the specific data they need. In traditional REST APIs, clients often receive more data than necessary (over-fetching), or they may need to make multiple requests to different endpoints to gather all the required data (under-fetching). GraphQL eliminates these issues by enabling clients to define the structure of the response.



2. **Reduced Number of Requests:**

  - GraphQL allows clients to send a single query to the server to retrieve all the needed data. This batching of queries in a single request reduces the number of network requests, improving efficiency and reducing latency.



3. **Flexibility and Versioning:**

  - GraphQL's schema-based approach provides flexibility in evolving APIs over time without breaking existing clients. When adding new features or fields, clients can adapt by requesting the additional data they need, and older clients can continue to function without modification.



4. **Real-time Updates:**

  - GraphQL supports real-time updates through subscriptions. Clients can subscribe to specific events, and the server pushes updates to the clients when relevant data changes. This is particularly useful for applications requiring live feeds, such as messaging apps or collaborative tools.



**Use Case Example:**



Consider a social media platform where users can post messages, and each message has information about the author, timestamp, and likes. In a traditional REST API, retrieving a user's posts along with the details of each post might involve multiple requests to different endpoints, resulting in over-fetching or under-fetching of data.



**REST API Approach:**



- Request 1: Retrieve user's posts

 ```

 GET /api/users/{userId}/posts

 ```



- Request 2 (for each post): Retrieve post details

 ```

 GET /api/posts/{postId}

 ```



This approach can lead to inefficiencies, especially if the client only needs specific information about each post, or if it wants to fetch posts along with the author's details in a single request.



**GraphQL Approach:**



The GraphQL query for the same scenario could be:



```graphql

query {

 user(id: "123") {

  name

  posts {

   id

   content

   timestamp

   likes

   author {

    id

    username

   }

  }

 }

}

```



In this single query, the client specifies the exact structure of the response it needs, including nested data about posts and their authors. The server processes this query and responds with precisely the requested data. This not only reduces the number of requests but also ensures that the client receives only the necessary information.



In summary, GraphQL simplifies data retrieval, reduces the number of network requests, offers flexibility in evolving APIs, and supports real-time updates.

STATISTICS FOR DATA ANALYTICS - 11

Sampling

Why do we need sampling ?
To draw valid conclusions from results, we need to carefully select a sample.


Type of Sampling.
Probability sampling
	Simple Random sampling
	Systematic sampling
	Stratified Sampling
	Cluster sampling

Non Probability sampling - Based on criteria.
	Convenience sampling 
	Voluntary response sampling
Purposive sampling.
Snowball sampling.


Methods to Detect Outliers

Due to outliers - 

Mean , Variance , Standard Deviation is highly affected.

Three Methods

Visualisation of data
Z-score
IQR ( inter quartile range )



Visualisation of data


Box-plot 

Histogram

Distribution Plot

Scatter Plot



Z-score


Any data point whose Z-score falls out of 3rd deviation is called outliers.


IQR ( inter quartile range )


In these we need 
Min 
Max 
Percentile of 25
Percentile of 75

To find out IQR 

IQR = Q3 - Q2

Lower fence = Q1 - IQR * 1.5

Higher fence = Q3 + IQR * 1.5

1.5 is experimental which is commonly used.

Above higher fence and lower than lower fence is taken as outliers.


How we can handle it

AWS IAM: A Beginner’s Guide
Tags: aws, cloud, devops, iam
Published: 2024-02-23 12:28:56

Amazon Web Services (AWS) offers a plethora of services, and Identity and Access Management (IAM) is a critical component for securing your AWS resources. In this blog post, we’ll demystify IAM, explore its features, and provide straightforward examples to help you grasp its importance.

## What is IAM?
IAM stands for Identity and Access Management. Let’s break it down:

- Identity: IAM helps you manage users, groups, and roles within your AWS account. These identities are essential for controlling access to AWS resources.
- Access Management: IAM allows you to define who can do what in your AWS environment. You can grant or restrict permissions based on roles and policies.

## Why Do We Need IAM?
Before IAM, managing access was chaotic:

- Shared Passwords: People shared passwords over insecure channels like email or phone calls.
- Single Admin Password: Only one admin password existed, stored in a vulnerable location.
- Lack of Security: Anyone could eavesdrop and gain unauthorized access.
IAM solves these problems by providing a secure way to manage access. Let’s dive deeper.

## Key Components of IAM
- Users: Represent individuals or applications. Each user has a unique set of credentials (username and password).
- Groups: Logical collections of users. Assign permissions to groups instead of individual users.
- Roles: Used by services or applications running on EC2 instances, Lambda functions, etc. Roles grant temporary permissions.

## IAM Examples
### 1. Creating a New User
- Log in to the AWS Console.
- Search for IAM and navigate to the IAM dashboard.
- Click “Users” and then “Add user.”
- Specify the username and choose access type (programmatic or console).
- Assign permissions (attach policies) to the user.

### 2. Creating a Group
- In IAM, click “Groups” and then “Create group.”
- Name the group (e.g., “Developers”).
- Attach policies to the group (e.g., “AmazonS3FullAccess”).
- Add users to the group.

### 3. Using Roles
- Create an IAM role (e.g., “LambdaRole”).
- Define the trusted entity (e.g., Lambda service).
- Attach policies (e.g., “AmazonDynamoDBFullAccess”).
- Lambda functions assume this role when executing.

## Conclusion
IAM is your gatekeeper to AWS resources. By understanding users, groups, and roles, you can control who accesses what. Remember, IAM is not just about security; it’s about enabling secure collaboration and efficient resource management.
What inspired me to become a fullstack developer
Tags: webdev, javascript, nextjs, android
Published: 2024-02-23 12:28:43

I received a review from a user of my study app, which I uploaded to the Play Store in 2021. The review said, "This app helped me, but it didn't cover all the courses in 100-level Electrical and Electronic Engineering. Still, I want to thank the creator of this app." This review brought back memories of how this app helped me and my classmates during our first year at university.

I created the app during the COVID-19 break. I worked day and night to answer past questions and compile notes on all the topics we were studying. To my surprise, I achieved a GPA of 4.78 in my first year at university by using the app during the first semester exams.

The most significant thing about the app was the encouragement I received from our Google Group leader (GDSC) at my school. They encouraged me to create my own Google Play account and upload the app myself so I could gain experience in app development and distribution.

Creating a Play Store account and having just one app in it motivated me to create more apps and upload them to the Play Store. It felt like having an empty store online, so I kept creating and uploading apps. This journey has brought me to where I am today as a full-stack developer. I believe my work will speak for itself.

My primary goal at university wasn't just to earn a degree but to build a significant app project to share with my friends. Since my first year, I've made progress towards that goal by creating various study apps for different departments and other apps not available on the Play Store.

Today, I'm proud to say that I'm a full-stack developer. I'm currently working on our e-commerce startup website and app with friends who share similar goals. Even though I'm still in my fourth year of school, I'm already living my biggest dream.

 https://ripplez.com.ng

Android app: 
https://play.google.com/store/apps/details...

The study App: https://play.google.com/store/apps/details...

I designed the website to resemble an app on mobile devices, knowing that I would eventually create an app using the same website. The website was built with Next.js 14, NextAuth v4, Tailwind CSS, TypeScript, Prisma, MongoDB, Resend for sending emails, and others online tools.

When I attempted to build an app using the website with Android Studio's WebView, I encountered unknown errors. I also faced issues with Capacitor due to the dynamic routes and APIs in my Next.js code. Although Flutter didn't yield positive results, I didn't give up. Finally, I tried React Native Expo WebView, and it worked perfectly for the Next.js website.

I owe thanks to my brother Daniel for his constant encouragement and early coding lessons. I also want to thank  @adrianhajdin,  @antonioerdeljac for his free coding tutorials, @chaoocharles  for his amazing tutorials and all my friends for their support. I hope to make you all proud someday.
