GoAvatar: Generate Unique Identicons in Go with Ease

Muhammad Saim — Sat, 22 Mar 2025 04:37:22 +0000

By Muhammad Saim

User avatars help create a recognizable identity in web apps, social platforms, and online communities. Instead of relying on uploaded images, identicons (automatically generated avatars based on input data) offer a unique, visually distinct way to represent users.

🚀 GoAvatar is an open-source Go package I created to generate unique, symmetric identicons from any input string (such as usernames or email addresses).

Identicons are perfect for applications that need quick, automatically generated profile images while maintaining uniqueness and consistency.

✨ Features

✅ Deterministic Identicons – The same input always generates the same avatar.

✅ Symmetric Designs – The generated icons are mirrored for a clean, balanced look.

✅ Customizable Sizes – Easily adjust the avatar size to fit your app's UI.

✅ Fast & Lightweight – Minimal dependencies for quick generation.

📦 Installation

To install GoAvatar in your project, run:

go get github.com/MuhammadSaim/goavatar

Then, import the package:

import "github.com/MuhammadSaim/goavatar"

🚀 Usage Example
Generating an identicon and saving it as an image is simple:

package main

import (
    "github.com/MuhammadSaim/goavatar"
    "image/png"
    "os"
)

func main() {

    // Generate the avatar with a custom foreground and background color
    options := goavatar.Options{
        Width:   128, // Set custom image width (default is 256)
        Height:  128, // Set custom image height (default is 256)
        BgColor: color.RGBA{170, 120, 10, 255},  // Change background color (default is light gray)
        FgColor: color.RGBA{255, 255, 255, 255}, // Change foreground color (default is extracted from hash)
    }
    avatar := goavatar.Make("EchoFrost7", options)
    // Generates an avatar with a brownish background and white foreground, saving it as avatar.png


    file, err := os.Create("avatar.png")
    if err != nil {
        panic(err)
    }
    defer file.Close()
    png.Encode(file, avatar)
}

🎨 The above code generates an identicon for "exampleUsername" at 128x128 pixels and saves it as "avatar.png".

🔍 Sample Identicons
Here are a few identicons generated with GoAvatar:

"QuantumNomad42"
"EchoFrost7"
"NebulaTide19"

Here are some unique identicons generated using GoAvatar:


QuantumNomad42	EchoFrost7	NebulaTide19

Every identicon is unique to the input string, making them perfect for user profiles, forums, and more!

Best way to learn a new Language/Framework: In My Opinion, Start with Small Projects and Scale It Large

Muhammad Saim — Mon, 13 Jan 2025 08:12:42 +0000

Learning a new language or framework can be daunting, but in my experience, the best way to truly understand it is through practical application. Instead of getting lost in endless tutorials and theory, start by building small, manageable projects.

https://github.com/MuhammadSaim/go-lab

Here's why this approach works:

Hands-on Learning: Using a language or framework is the best way to get comfortable with it. Writing code for real-world applications allows you to tackle the specific challenges that tutorials don't cover.
Iterative Growth: Start small. Don’t jump into large projects right away. A simple to-do app or basic API can give you a solid foundation. As you get more comfortable, gradually scale the project to incorporate more complex features and functionalities.
Focused Learning: Small projects force you to focus on one thing at a time, such as mastering the new syntax or familiarizing yourself with the framework's or tooling's conventionalizing. You'll learn better when you're hen not overwhelmed.
Building Confidence: Building confidence is through every small project. Each little success propels you toward the next challenge. Knowledge from a small project is the building block of a much larger solution in a scaled-up environment.
Portfolio Development: These tiny projects will begin to form the basis of your portfolio. The more you build them out, the more you can demonstrate how your skills grow through tangible work reflecting your progress.

So, if you're starting from a new language or framework, jump in with small projects and, as you build, scale them larger. You'll be amazed at how fast you will learn, and before you know it, you will have the skills to tackle more complex problems!

A Personal Experience with Learning Go

I initially tried to learn GoLang through various tutorials to get a handle on the basic syntax and concepts. As a busy software engineer, however, I found it hard to dedicate the time to learn things conventionally. I explored content from YouTubers like AnthonyGG, Mikey, and others to familiarize myself with Go, but it wasn’t until I started following Akhil Sharma’s project-based series on YouTube that things clicked.

The series is almost three years old, covering Go1.18 or earlier versions, but I’m currently working with Go1.24, which introduces more limitations and new challenges. These limitations force me to think creatively and problem-solve in ways that I wouldn't have anticipated if I had just followed the tutorials verbatim. It’s been a steep learning curve, but solving these issues as I go has been incredibly rewarding.

This experience shows that, even with a dated tutorial series, diving into projects forces you to adapt and grow, which accelerates your learning in a way that just following tutorials alone never could.

So, if you're starting with a new language or framework, dive in with small projects, and as you build, scale them larger. You'll be surprised how quickly you'll learn, and before you know it, you'll have the skills to tackle more sophisticated problems!

Setting Up Your GoLang Environment

Muhammad Saim — Fri, 07 Jun 2024 06:30:00 +0000

Setting Up Your GoLang Environment

Golang, commonly known as Go, is an open-source programming language developed by Google. Known for its simplicity, efficiency, and strong concurrency support, Go is a great choice for building modern applications. In this guide, we'll walk you through setting up a Go environment on your local machine.

Prerequisites

Before we start, ensure you have the following:

A computer with a modern operating system (Windows, macOS, or Linux).
An internet connection to download Go.

Step 1: Download Go

First, we need to download the Go installer from the official website.

Open your web browser and go to the Go download page.
Select the installer for your operating system and download it.

Step 2: Install Go

Windows

Locate the downloaded .msi file and double-click it.
Follow the prompts to install Go. The default settings are usually fine.
After installation, open the Command Prompt and type:
```
go version
```
You should see the Go version, confirming the installation.

macOS

Locate the downloaded .pkg file and double-click it.
Follow the instructions in the installer.
Open the Terminal and type:
```
go version
```
You should see the Go version information.

Linux

Open the Terminal.
Extract the downloaded tarball to /usr/local:
```
sudo tar -C /usr/local -xzf go1.xx.x.linux-amd64.tar.gz
```
Replace 1.xx.x with the actual version you downloaded.
Add Go to your PATH. Open or create the ~/.profile file and add:
```
export PATH=$PATH:/usr/local/go/bin
```
Apply the changes by running:
```
source ~/.profile
```
Verify the installation by typing:
```
go version
```
You should see the Go version information.

Step 3: Set Up Your Go Workspace

Now that Go is installed, we need to set up a workspace for your Go projects.

Create a directory for your Go workspace. For example, in your home directory:
```
mkdir -p ~/go
```
Inside this workspace, create three subdirectories:
```
mkdir -p ~/go/{bin,pkg,src}
```

- `bin` for compiled binaries.
- `pkg` for package objects.
- `src` for source code.

Set the GOPATH environment variable to your workspace. Add this line to your ~/.profile file (or the equivalent for your shell):
```
export GOPATH=$HOME/go
```
Apply the changes:
```
source ~/.profile
```
Verify the GOPATH by running:
```
go env GOPATH
```
It should return the path to your workspace (~/go).

Step 4: Write and Run a Simple Go Program

Let’s test your Go environment by writing a simple Go program.

Create a directory for your project inside src. For example:
```
mkdir -p ~/go/src/hello
```
Create a new file named hello.go in this directory:
```
nano ~/go/src/hello/hello.go
```

Add the following code to hello.go:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Go!")
}

Save the file and exit the editor.
Compile and run your program:
```
go run ~/go/src/hello/hello.go
```
You should see the output:
```
Hello, Go!
```

Step 5: Explore More

Congratulations! You've successfully set up Go on your machine and run your first Go program. Here are a few more steps to deepen your Go knowledge:

Explore Go Documentation.
Try out more Go projects and tutorials.
Join Go communities and forums for support and networking.

Conclusion

Setting up Go is a straightforward process. With your Go environment ready, you can start building efficient, concurrent applications. Happy coding!

Discover the Magic Behind YouTube's Unique Video IDs

Muhammad Saim — Sat, 18 May 2024 19:54:10 +0000

Understanding YouTube's Unique Video IDs: An Exploration of Base 64 Encoding

Every YouTube video has a unique identifier embedded in its URL. This ID, a string of eleven characters, is crucial for distinguishing the vast array of videos on the platform. Considering YouTube's immense scale—400 hours of video uploaded every minute—it’s natural to wonder: will YouTube ever run out of these unique IDs?

Counting Systems and Their Efficiency

To grasp the robustness of YouTube's ID system, it's essential to understand different counting systems:

Base 10 (Decimal): The most familiar system, using digits 0-9.
Base 2 (Binary): Utilized by computers, comprising only 0 and 1.
Base 16 (Hexadecimal): A more compact form for binary data, using 0-9 and A-F.

For YouTube, however, these systems would either be too cumbersome or not compact enough to handle the vast quantity of videos efficiently.

The Power of Base 64

YouTube employs Base 64, an efficient and compact counting system:

Composition: Base 64 uses 0-9, A-Z, a-z, and two URL-friendly characters (hyphen and underscore) instead of the typical slash and plus.
Efficiency: This system allows a vast number of unique combinations, making it perfect for generating unique video IDs in a compact form.

Why Not Incremental Counters?

Using simple incremental counters (1, 2, 3, etc.) would seem straightforward but poses significant challenges:

Synchronization Issues: Multiple servers handling uploads would need precise coordination to avoid duplicate IDs.
Security Risks: Sequential IDs make it easy to guess and access neighboring content, which is problematic for privacy and security.

Instead, YouTube generates random IDs, checking their uniqueness before assignment, thus sidestepping these issues effectively.

The Immense Capacity of Base 64

The true power of YouTube's system lies in its capacity:

One Character: 64 unique IDs.
Two Characters: 4,096 unique IDs.
Three Characters: Over 262,000 unique IDs.
Eleven Characters: Approximately 73 quintillion unique IDs.

With this structure, YouTube's ID system can theoretically support every human on Earth uploading a video every minute for 18,000 years without exhausting available IDs.

Python Code for Generating Unique YouTube-style IDs

Below is a Python implementation of generating unique YouTube-style video IDs using a Base 64 encoding scheme. This code simulates the generation of these IDs, ensuring they are unique and not already taken.

import random
import string

# Define the characters used in YouTube's Base 64 ID
BASE64_CHARS = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-_'
BASE64_LENGTH = len(BASE64_CHARS)
ID_LENGTH = 11  # YouTube uses 11-character IDs

def generate_base64_id(length, chars, chars_length):
    """
    Generate a random Base 64 ID of a given length.

    Args:
    length (int): The length of the ID to generate.
    chars (str): The characters to use for generating the ID.
    chars_length (int): The length of the character set.

    Returns:
    str: A randomly generated ID.
    """
    id = ''.join(random.choice(chars) for _ in range(length))
    return id

# Simulate a list of existing IDs to check for uniqueness
existing_ids = []

def id_exists(id, existing_ids):
    """
    Check if an ID already exists in the list of existing IDs.

    Args:
    id (str): The ID to check.
    existing_ids (list): The list of existing IDs.

    Returns:
    bool: True if the ID exists, False otherwise.
    """
    return id in existing_ids

def generate_unique_id(length, chars, chars_length, existing_ids):
    """
    Generate a unique ID that does not already exist in the list of existing IDs.

    Args:
    length (int): The length of the ID to generate.
    chars (str): The characters to use for generating the ID.
    chars_length (int): The length of the character set.
    existing_ids (list): The list of existing IDs to check against.

    Returns:
    str: A uniquely generated ID.
    """
    while True:
        new_id = generate_base64_id(length, chars, chars_length)
        if not id_exists(new_id, existing_ids):
            existing_ids.append(new_id)
            return new_id

# Example usage
if __name__ == "__main__":
    new_id = generate_unique_id(ID_LENGTH, BASE64_CHARS, BASE64_LENGTH, existing_ids)
    print("Generated YouTube-style ID:", new_id)

    # Generate and print 5 unique YouTube-style IDs
    for _ in range(5):
        print(generate_unique_id(ID_LENGTH, BASE64_CHARS, BASE64_LENGTH, existing_ids))

# Output
# Here are five unique YouTube-style IDs generated by the function

8Cg87WioslZ
6YkZou-YJNm
FwX-5pTiuZG
fF4paGWjxTi
fYyzw4ELXj3

This code ensures that each generated ID is unique by checking against a simulated database of existing IDs. The approach is scalable to handle many unique IDs, just like YouTube’s system.

Future-Proofing

Even in the improbable event that YouTube approaches this limit, adding just one more character to the ID length would exponentially increase the number of available combinations, ensuring continued scalability.

Conclusion

YouTube's choice of Base 64 for generating unique video IDs demonstrates a forward-thinking approach to handling vast amounts of data efficiently and securely. The system's immense capacity and flexibility ensure that, practically, YouTube will never run out of unique IDs, keeping the platform robust and future-proof.

Creating SEO-Friendly Slugs in Laravel: A Step-by-Step Guide

Muhammad Saim — Fri, 17 May 2024 05:30:00 +0000

Creating SEO-Friendly Slugs in Laravel: A Step-by-Step Guide

In today's digital age, having SEO-friendly URLs is crucial for improving your website's visibility on search engines and enhancing user experience. In this guide, we'll show you how to generate SEO-friendly slugs in Laravel, making your URLs more readable and user-friendly.

Understanding the Importance of Slugs

A slug is a simplified version of a string that represents a resource's title or name in a URL. By optimizing your slugs, you can make your URLs more descriptive and easier for both users and search engines to understand. This can have a positive impact on your website's search engine rankings and overall user engagement.

Implementing Slug Generation in Laravel

To generate SEO-friendly slugs in Laravel, we'll use a trait-based approach. First, we'll create a trait file named GeneralHelpers in the App\Traits directory. Inside this trait, we'll define a function called generateSlug that generates a unique slug for a given model.

Here's how the generateSlug function works:

<?php

namespace App\Traits;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

trait GeneralHelpers
{
    /**
     * Generate a unique slug for a model.
     *
     * @param Model $model The model instance for which the slug is generated.
     * @param string $title The title from which the slug is derived.
     * @param string $column The column name to check for uniqueness.
     * @return string The generated unique slug.
     */
    public function generateSlug(Model $model, string $title, string $column = 'slug'): string
    {
        // Create a slug from the title using Laravel's Str::slug method
        $slug = Str::slug($title);

        // Check if the generated slug already exists in the specified column of the model's table
        $checkSlug = $model::query()->where($column, $slug)->first();

        // If the slug already exists, append a random string to make it unique
        if ($checkSlug) {
            // Append a random string to the original title to create a new slug
            $title = sprintf("%s %s", $title, Str::random(mt_rand(5, 10)));

            // Recursively call the function with the updated title to generate a new slug
            return $this->generateSlug($model, $title, $column);
        }

        // If the slug is unique, return it
        return $slug;
    }
}

Understanding the `generateSlug` Function

The generateSlug function is responsible for creating a unique slug for a given model. Here's a breakdown of how it works:

Create Slug: It first generates a slug from the provided title using Laravel's Str::slug method. This method converts the title to a URL-friendly slug by replacing spaces with hyphens and removing special characters.
Check Uniqueness: Next, the function checks if the generated slug already exists in the specified column of the model's table. If a record with the same slug exists, it means the slug is not unique, and we need to generate a new one.
Make Slug Unique: If the generated slug is not unique, the function appends a random string to the original title and recursively calls itself with the updated title to generate a new slug. This process continues until a unique slug is generated.
Return Slug: Once a unique slug is generated, the function returns it.

Next, we'll use this trait in our controller, such as the PostController, to generate slugs when creating new posts:

<?php

namespace App\Http\Controllers;

use App\Models\Post;
use App\Traits\GeneralHelpers;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;

class PostController extends Controller
{
    use GeneralHelpers;

    /**
     * Create a new post.
     *
     * @param Request $request The HTTP request containing the post data.
     * @return RedirectResponse The response redirecting back to the form page.
     */
    public function store(Request $request): RedirectResponse
    {
        // Validate the post data
        $data = $request->validate([
            'title' => 'required',
            'body' => 'required',
        ]);

        // Create a new Post model instance
        $post = new Post;

        // Create the post with the generated slug
        $post::query()->create([
            'title' => $data['title'],
            'slug' => $this->generateSlug($post, $data['title']),
            'body' => $data['body'],
        ]);

        // Redirect back to the form page with a success message
        return redirect()->back()->with('success', 'Post created successfully');
    }
}

Conclusion

Generating SEO-friendly slugs in Laravel is a simple yet powerful way to improve your website's SEO performance. By using the generateSlug function and incorporating it into your Laravel applications, you can ensure that your URLs are both user-friendly and optimized for search engines.

Handling Nullable Relationships in Laravel Models: Best Practices vs. Manual Checks

Muhammad Saim — Thu, 16 May 2024 05:30:00 +0000

Handling Nullable Relationships in Laravel Models: Best Practices vs. Manual Checks

When dealing with relationships in Laravel models, such as the author relationship in a Post model, it's essential to consider the best practices for handling nullable relationships. Let's explore the best and bad approaches to handle such scenarios:

class Post extends Model
{
    public function author(): BelongsTo
    {
        // Defines the relationship between Post and User models, where each post belongs to an author.
        return $this->belongsTo(User::class)
                    // If the author_id in the Post is null, the author relationship will not return null but a new User model.
                    // The new User model's name is set to 'Guest Author' by default.
                    ->withDefault([
                        'name' => 'Guest Author'
                    ]);
    }
}

Explanation:

Utilizes Laravel's withDefault method to specify default values for attributes of related models.
Ensures that if the author_id in the Post model is null, it returns a new User model with the name attribute set to 'Guest Author'.
Eliminates the need for explicit checks for null values when accessing the author's name, providing a cleaner and more concise way to handle such scenarios.

$authorName = $post->author ? $post->author->name : 'Guest Author';

Explanation:

Requires manual null checks ($post->author ? ... : ...) to handle nullable relationships.
Leads to repetitive and verbose code snippets every time the author's name is needed.
Increases the chances of forgetting null checks, potentially causing runtime errors if accessed without validation.

In conclusion, leveraging Laravel's withDefault method offers a cleaner and more efficient solution for handling nullable relationships, ensuring a smoother development experience and reducing the likelihood of errors compared to manual null checks.

Laravel Relationship Recipes: Simplify Querying with hasManyThrough

Muhammad Saim — Wed, 15 May 2024 05:30:00 +0000

Laravel Relationship Recipes: Simplify Querying with hasManyThrough

In today's edition of Laravel Relationship Recipes, we'll explore the hasManyThrough relationship method, a powerful feature that simplifies querying related models through an intermediate model.

Understanding the Scenario

Consider a scenario where you have three models: Department, Employee, and Paycheck. Each department has multiple employees, and each employee has multiple paychecks. To retrieve all the paychecks within a department, you can utilize the hasManyThrough relationship.

Introducing the hasManyThrough Method

In your Department model, you can define a paychecks relationship using hasManyThrough:

class Department extends Model
{
    public function employees(): HasMany
    {
        return $this->hasMany(Employee::class);
    }

    public function paychecks(): HasManyThrough
    {
        return $this->hasManyThrough(Paycheck::class, Employee::class);
    }
}

The hasManyThrough method takes two arguments: the related model (Paycheck in this case) and the intermediate model (Employee). With this relationship in place, you can now easily retrieve all the paychecks within a department.

Simplifying Querying

Instead of writing complex nested queries, you can now simply use the paychecks relationship on the Department model:

$department->paychecks;

Laravel Relationship Recipes: Leveraging Custom Logic with ofMany

Welcome back to our Laravel Relationship Recipes series! Today, we're exploring the versatile ofMany relationship method in Laravel Eloquent, which allows you to incorporate custom logic when querying related models.

Understanding the Scenario

Consider a scenario where you have a Post model with a like_count attribute, and you want to retrieve the post with the highest number of likes. Instead of writing custom queries every time, you can utilize the ofMany method to achieve this.

Introducing the ofMany Method with Custom Logic

In your Post model, you can define a relationship method mostPopularPost as follows:

public function mostPopularPost()
{
    return $this->hasOne(Post::class)
                ->ofMany('like_count', 'max');
}

By using the ofMany method and specifying the like_count attribute along with the aggregation function max, Laravel will automatically retrieve the post with the highest like_count.

Custom Logic Possibilities

The ofMany method opens up various possibilities for incorporating custom logic into your relationships. Whether you need to retrieve the oldest, newest, or most popular model based on specific attributes, you can leverage this method to streamline your code and improve readability.

Conclusion

The ofMany relationship method in Laravel Eloquent provides a powerful way to incorporate custom logic when querying related models. By utilizing this method, you can avoid writing repetitive custom queries and maintain cleaner, more maintainable code.

Laravel Relationship Recipes: Simplify Querying with newestOfMany

Welcome back to our Laravel Relationship Recipes series! Today, we're introducing another handy method in Laravel Eloquent relationships: newestOfMany. This method simplifies querying for the newest model in a hasMany relationship.

Understanding the Scenario

Consider the scenario where you have an Employee model with a hasMany relationship to Paycheck models. You constantly need to retrieve the newest paycheck for each employee.

Introducing the newestOfMany Method

Similar to oldestOfMany, you can create a relationship method for the newest model in your Employee model:

class Employee extends Model
{
    public function latestPaycheck()
    {
        return $this->hasOne(Paycheck::class)->latestOfMany();
    }
}

By using the hasOne method and chaining latestOfMany, Laravel will automatically retrieve the newest paycheck for each employee.

Limitations

As with oldestOfMany, it's important to note that the newestOfMany method relies on auto-increment IDs to determine the newest model. If you're using UUIDs as foreign keys, this method won't work as expected.

Conclusion

The newestOfMany method in Laravel Eloquent relationships provides a convenient way to retrieve the newest model in a hasMany relationship without the need for custom queries. By leveraging this method, you can simplify your code and improve maintainability.
