Never-Blink

1. 🎉 Introduction

Randomly connect to a player around the world and challenge him/her. Remember not to blink!

2. 📜 Implementation

1. Project structure

.
├── backend
│   ├── __init__.py
│   ├── detect.py
│   └── shape_predictor_68_face_landmarks.dat (detect model)
├── package.json
├── requirements.txt
├── server.py
├── src
│   ├── app.jsx
│   ├── index.js
│   ├── play.jsx
│   └── start.jsx
├── static
│   └── bundle.js
├── templates
│   └── index.html
└── webpack.config.js

The project uses react as our frontend framework, and uses peerjs to communicate between clients. At the backend, we use flask to host the server. For the connection between clients and server, we use socketio to implement real-time data transfer.

2. Game State

It uses the notion of Finite State Machine to design our game state. The circle is the state. The text in the top of each box is the event causing state transition, and the text in the bottom of each box is the action taken when an event occurs. The logic looks quite simple here, but it is not that easy to implement. For more detail you can check play.jsx or server.py.

Start and Enjoy

Go to https://0.0.0.0:3000

0.0.0.0:3000 does not work, remember to add https.

4. 🚧 Problem

Because the detector is too slow and weak, we can not endure too many clients. Therefore, we do not deploy it to a public server now. We plan to train a robust and fast model in the future.
When restarting, the old media connection listener will be called again. So we remove restart temporarily.

Why and How to contribute to open source???

Vikas Kumar — Tue, 03 Dec 2019 09:02:35 +0000

Hello there, I am Vikas Kumar student of 2nd-year Information technology B.tech from CBP Government Engineering college

I have been asked by so many students that what is open source, how can I contribute to it? Is it helpful if I contribute to open source, and the list goes on relevant to “Open Source”.

So what is open source???

According to opensource.com The term “open-source” refers to something people can modify and share because its design is publicly accessible.

The term originated in the context of software development to designate a specific approach to creating computer programs. Today, however, “open source” designates a broader set of values — what we call “the open source way.” Open source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development. i.e., “open-source is what is free to access by all. Anyone can change and distribute its own model”.

There are so many blogs available on the internet to learn about open source, software and their importance. I won’t be discussing its importance in this article here my main concern is “How to contribute to open-source?”

The most common and widely used platform to contribute to open source is Git and GitHub.

The purpose of Git is to manage a project, or a set of files, as they change over time. Git stores this information in a data structure called a repository. A git repository contains, among other things, the following: A set of commit objects.

GitHub is a Git repository hosting service, but it adds many of its own features. While Git is a command-line tool, GitHub provides a Web-based graphical interface. It also provides access control and several collaboration features, such as wikis and basic task management tools for every project.

Here I will Teach You some of the command used in git to push, pull, commit and do changes to your GitHub repository.

First, install Git from the official site https://git-scm.com/downloads and install it in your PC then after creating your profile on Github https://github.com, make a repository and clone (copy the link of your repository) your repository with HTTPS.

Now go to Git Bash software and use this command to clone this repository to your PC.

git clone [your copy link]

Git Bash don’t use ctrl+V to paste any segment so paste your link by using shift+Ins key

Now you have cloned your Github repository to your system now add all you relevant codes in that cloned directory to upload it to your GitHub Profile.

Now when you will type command git status you will see all those files you have added to the directory in red-coloured untracked file segment like this. Here laddu.txt is my unracked file what I have just moved to the directory.

Now to add these files into staging area (Staging is a step before the commit process in git. That is, a commit in git is performed in two steps: staging and actually commit. As long as a changeset is in the staging area, git allows you to edit it as you like to replace staged files with other versions of staged files, remove changes from staging, etc.) use command git add <files_Name with their respective extensions>

Here you can see that now your files are successfully added to the staging area. Now you need to commit these files with a description. And to do so use git commit -m “Your description”

Now we have committed these changes in our local system and to upload these changes to our remote profile use git remote -v

Great, Now just one step left this is to push these changes in our Github repository. use git push origin master command to upload your files or any changes.

Great You have successfully uploaded your files to your GitHub repository.

All the files and directories are uploaded to your Github account. Now you can manage, revert, access or do any changes in your repositories like this. If you need any other help DM me I will add or post another article relevant to issues raised by majorities.

You can also earn some cool swags if you contribute to open source

How to create Alexa skill

Vikas Kumar — Fri, 29 Nov 2019 08:44:33 +0000

Introduction to Amazon Alexa and Alexa skill

Amazon Alexa, known simply as Alexa, is a virtual assistant developed by Amazon, first used in the Amazon Echo and the Amazon Echo Dot smart speakers developed by Amazon Lab126. It is capable of voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic, sports, and other real-time information, such as news. Alexa can also control several smart devices using itself as a home automation system. Users are able to extend the Alexa capabilities by installing “skills” (additional functionality developed by third-party vendors, in other settings more commonly called apps such as weather programs and audio features).

Prerequisites for developing Alexa skill

It is obvious that you should have an amazon developers account. And you must have AWS Lamda for the easiest backend support.

Steps to follow for your Alexa skill

Give the skill a unique name with a default language. You can choose the model to add to your skill and multiple methods to host your skill’s backend resources but I would prefer you to go with the custom that will be mentioned as custom and provision your own respectively.

Choose a template

Go for the Start from scratch

The screen will look like this once click on start from scratch and the browse completes.

Lambda Functions

Now go to the aws.amazon and create an AWS Lambda function.

Here in its index.js file, we have an Intent named GetNewFactIntent that will contain our data on what Alexa will respond to our queries. And in the const data array, we can add the facts.

Copy ARN number

Copy the ARN number in the top right corner and paste it to the endpoint in the Alexa skill console. Now go to Intent and add an Intent with the same name GetNewFactIntent to sync the array facts and give some sample utterances related to your skill. I developed the skill Interesting facts of Bihar that is why is used this array of words repeatedly in my sample utterances.

Sample utterances

after filling up for the required utterances just save and build your model and then you to the Test section.

Test your skill

Test your skill for multiple times to get rest assured for the quality of your Amazon skill. After that go to distribution, all the other requirements are basic and I am sure that will do it if still, you find any issue then you can mail me or ask me in the response section below.
