Background

This project was inspired by the need to streamline the workflow for open-source maintainers. We observed that labelling issues was a recurring task that could be automated to save maintainers time and effort. We chose to participate in the Maintainer Must-Haves category for the GitHub + DEV 2023 Hackathon, as we believed this was a valuable tool that could assist many maintainers.

How We Built It

We utilized GitHub Actions to create a workflow that triggers whenever a new issue is created. This workflow runs a script that analyzes the issue description and extracts labels based on predefined keywords. The script then adds these labels to the issue.

We also made use of GitHub Codespaces to develop and test our code. This made it easy for our team to collaborate and ensured that we had a consistent development environment.

During the project, we learned a great deal about GitHub Actions and Codespaces, including how to create custom workflows and how to set up a development environment in Codespaces.

Book CoWIN Vaccination Slots directly from your Terminal...

Dhruv Panchal — Sun, 23 May 2021 07:33:32 +0000

Introduction

CoWIN Portal is used to self-register yourself for the Vaccination process in India. Here you can register yourself with your Phone Number and avail a slot from the available slots in various Vaccination Centres around the country.

About

VacCowin is a CLI based Python Script that can be used to perform tasks such as OTP Generation till Vaccination Slot Booking from Co-WIN Platform directly from your Terminal. This script rechecks after every few seconds and when the slots are available, it confirms the slot only after you enter the captcha shown on the screen.

Since India has started the Vaccination Drive for those above 18 years of age, there is a very heavy rush and slots get booked soon. This script will come in handy for booking those slots as soon as they open.

IMPORTANT: This is a Proof of Concept (POC) Project. I OR the Team do NOT endorse or condone, in any shape or form, automating any monitoring/booking tasks. It's only made for Educational Purposes. Use this at your own risk.

The data used is retrieved using the open APIs at API Setu. It works on both Linux and Windows.

Important:

This is a Proof of Concept Project. I OR the Team do NOT endorse or condone, in any shape or form, automating any monitoring/booking tasks. It's only made for Educational Purposes. Use this at your own risk.
This Python Script CANNOT book slots automatically. It doesn't skip any of the steps that a User would have to take on the official portal. You will still have to enter the OTP and Captcha as you do in the CoWIN Portal.
Do NOT use unless all the beneficiaries selected are supposed to get the same Vaccine and Dose.
There is no option to Register a new Phone/Mobile or add beneficiaries for now. This can be used only after beneficiary has been added through the official Portal/App.
Be careful if you're choosing to use the auto-book feature. It will blindly select first available Vaccination Centre, Date (Both Sorted Ascending) and a RANDOM slot. I would not recommend using this feature unless and until it's crucial.
If you accidentally booked a slot you didn't want to then don’t worry. You can always log in to the CoWIN Portal and cancel/re-schedule that.

Pixxia - Compress your Images in Optimal Quality for FREE

Dhruv Panchal — Sun, 18 Apr 2021 04:45:06 +0000

Introduction:

The above script uses lossy compression methods to reduce the document size of your JPG/PNG files. This is achieved by rounding up the (R,G,B) values from each pixel of it's unit digit in your image, therefore lesser number of bytes are required to store the information. Sometimes, there are major changes in the bytes stored well as sometimes there are minor changes so it depends entirely on the pixels of the image.

dhhruv / Pixxia

🖼 Pixxia uses lossy compression methods to reduce the document size of your JPG/PNG files.

Image Comparison:

For Images >= 6 MB you may see a great compression ratio as compared to the images which are smaller than that.

Download Pixxia.exe for Windows

Setup (Windows):

Install Python
Clone this repository

git clone https://github.com/dhhruv/Pixxia.git

Install, create and activate virtual environment. For instance we create a virtual environment named 'venv'.

Click CLEAR Button to reset the input fields and status bar. (If needed)

NOTE: Recommended to keep INPUT and OUTPUT Folder different for your ease to differentiate between Optimized and Unoptimized Images.

Important Note:

This Script goes through each pixel of every supported image in the INPUT folder so it'll take more time than usual to process the Image.
This Script is just a Prototype so results may be unexpected.
The Authors will not be responsible for any kind of loss of data so it is essential to have a Backup of Original Data placed in the Input Folder. Read the LICENSE for more information.

Tic-Tac-Toe you can't beat...

Dhruv Panchal — Sat, 17 Apr 2021 18:13:29 +0000

In order to make the traditional Tic Tac Toe Game unbeatable, it is necessary to create an algorithm that can calculate all the possible moves available for the Computer and can use that to determine the best possible move.

Introduction

To solve games using AI, we will introduce the concept of a Game Tree followed by Minimax algorithm. This algorithm sees a few steps ahead and puts itself in the shoes of its opponent. It keeps playing ahead until it reaches a terminal arrangement of the board (terminal state) resulting in a tie, a win, or a loss. Once in a terminal state, the AI will assign an arbitrary positive score (+10) for a win, a negative score (-10) for a loss, or a neutral score (0) for a tie.

At the same time, the algorithm evaluates the moves that lead to a terminal state based on the players’ turn. It will choose the move with maximum score when it is the AI’s turn and choose the move with the minimum score when it is the human player’s turn. Using this strategy, Minimax avoids losing to the human player.

What is Minimax?

Minimax (sometimes MinMax, MM or saddle point) is a decision rule used in artificial intelligence, decision theory, game theory, statistics, and philosophy for minimizing the possible loss for a worst case (maximum loss) scenario. When dealing with gains, it is referred to as "maximin" - to maximize the minimum gain. Originally formulated for n-player zero-sum game theory (one player wins (+10) and other player loses (-10) or both of anyone not to win (0)), covering both the cases where players take alternate moves and those where they make simultaneous moves, it has also been extended to more complex games and to general decision-making in the presence of uncertainty.

How does it work?

To check whether or not the current move is better than the best move we take the help of minimax function which will consider all the possible ways the game can go and returns the best value for that move, assuming the opponent also plays optimally until it finds a terminal state (win, draw or lose).

Explanation:

This image depicts all the possible paths that the game can take from the root board state. It is often called the Game Tree.
The 3 possible scenarios in the above example are :

Left Move : If X plays [2,0]. Then O will play [2,1] and win the game. The value of this move is -10
Middle Move : If X plays [2,1]. Then O will play [2,2] which draws the game. The value of this move is 0
Right Move : If X plays [2,2]. Then he will win the game. The value of this move is +10;

Remember, even though X has a possibility of winning if he plays the middle move, O will never let that happen and will choose to draw instead.
Therefore the best choice for X, is to play [2,2], which will guarantee a victory for him.

Explaining Stack in Detail

Dhruv Panchal — Fri, 16 Apr 2021 05:06:50 +0000

Stack

Stacks are the result of approaching a LIFO (Last in, First out) ordering with list node connection behavior. This means that element inside the stack are connected like a list but are added and extracted approaching LIFO.

[1] Lifo stack | https://commons.wikimedia.org/wiki/File:Lifo_stack.png

Based on that, the to methods that a stack should have to be called that way are pop which remove the top element from the stack and returns it, and push which adds a new element on top of the stack.

Minimal methods to work with `Stacks`

- `Pop`

Java implementation of the pop method in an array based stack

public Object pop() {
        if (!isEmpty()) {
            Object object = array[top];
            array[top--] = null;
            return object;
        } else {
            return null;
        }
    }

As you see, after obtaining the element in top of the stack, it is immediately removed from it.

- `Push`

Java implementation of the push method in an array based stack

public boolean push(Object object) {
    if (top + 1 < size) {
        try {
            array[++top] = object;
            return true;
        } catch (Exception e) {
            System.out.println(e);
            return false;
        }
    } else {
        return false;
    }
}

- `Peek`

In some circumstances the user may want to check the value stored in the top of the stack without removing it. In this scenarios is where peek method is useful, since it return the value without removing it from the stack. This way and extra push is not necessary.

Java implementation of peek in a Array based stack

public Object peek() {
    return (!isEmpty()) ? array[top] : null;
}

Array and List based stacks

Example of an array based stack, of four elements. It will only receive four elements, if it reach it's max length, incoming values were not be added.

[2] Stack (data structure) LIFO | https://commons.wikimedia.org/wiki/File:Stack_(data_structure)_LIFO.svg

The mayor difference between an array based stack and one implemented using lists is that the first one is usually implemented with a static size, this means that it will only accept a specific number of element, the other one, will allow the user to add elements until memory is full.
