The MindMates open collaborative crowdsourcing platform was built in occasion of the 2020 Hackerearth Hackccelerate by team MindMates.
The platform can be explored at https://mindmates.mooo.com/
As schools around the world respond to the “new normal”, the need for remote learning tools has never been more urgent. Calling out all developers to build solutions that can help schools, educators, students, and their families to make the transition to distance learning easier.
Develop pseudo distance learning applications or online educational tools for remote learning that allow users to interact and a “classroom-like” environment.
MindMates is the first open collaborative crowdsourcing network where classmates can meet and propose project ideas and get direct collaboration and help ('backing') from peers by completing and submitting tasks defined by the team leader. Students, teachers and parents can meet virtually among each other. Group projects can be started and managed on the online platform with the supervision of other classmates, teachers and parents. Teachers are provided tools to write articles and insert material into the website through a wiki and a blog. Students can add wiki articles to their personal watchlist and discuss teachers' articles. Group projects, once finished, can be archived in the 'Projects to discover' section of the website.
We think this innovative solution can bring a smoother and easier experience when it comes to managing group projects and learning remotely, compared to traditional remote communication tools like Facebook, WhatsApp or Moodle.
This web app was deployed with AWS. In order to use their cloud infrastructure, you have to register an account at https://portal.aws.amazon.com/billing/signup first. Provide the requested information and, once logged in, you'd want to create an EC2 instance.
Choose a Bitnami WordPress instance. Click on 'Launch instance' and in the AWS Marketplace search for "WordPress with NGINX and SSL Certified by Bitnami and Automattic". You can select the free tier to test the web app.
SSH to the instance, install Git, go to WordPress themes folder and clone the repository into it:
chmod 400 mindmateskeypair.pem
ssh -i "mindmateskeypair.pem" bitnami@ec2-x-xxx-xxx-xx.eu-central-1.compute.amazonaws.com
sudo -i
apt-get install git
cd /opt/bitnami/apps/wordpress/htdocs/wp-content/themes
git clone https://github.com/trajkd/MindMates-wp.git
Remove the Bitnami banner by typing the following in the console:
sudo /opt/bitnami/apps/wordpress/bnconfig --disable_banner 1
sudo /opt/bitnami/ctlscript.sh restart nginx
Now open the public IP address of your instance, go to /wp-admin and enter the default username and password that you can find by typing the following in the console:
sudo cat /home/bitnami/bitnami_credentials
Add a new administrator, log out from user, and log in with the newly created credentials. You can delete the default user now.
We've provided a backup file to load with the Updraft Plus backup plugin. It includes all the basic setup you need for the web app to work properly. You will only have to change some fields, like SMTP settings and the main URL of the application. Look in the Manual configuration below to see which fields you will need to change. The backup file also contains some example database entries. You can remove them and start from scratch if you want.
Go to Appearence > Themes and activate the theme MindMates-wp Go to Appearence > Customize > Site Identity and set the site title and the site icon as static/img/mindmates-blue-logo.jpg and hit Publish. (You might want to clone the repository to your local machine too in order to complete this operation)

The platform uses AWS's DynamoDB and S3 services to store some data via the AWS SDK for JavaScript. To get acquainted with it, read the official documentation.
After you successfully create an Identity Pool for unauthenticated users, you'll need to change these lines in the code inside static/js/editidea.js (lines 509-516), static/js/ideas.js (lines 63-68) and static/js/viewideas.js (lines 1-6):
var myCredentials = new AWS.CognitoIdentityCredentials({IdentityPoolId:'eu-central-1:dbfaca2d-0214-4100-9f00-e82d3b15c7ba'});
var myConfig = new AWS.Config({credentials: myCredentials, region: 'eu-central-1'});
AWS.config.update({credentials: myCredentials, region: 'eu-central-1'});
var dynamodb = new AWS.DynamoDB({apiVersion: '2012-08-10'});
var s3 = new AWS.S3({apiVersion: "2006-03-01",params: { Bucket: "mindmates" }});
In particular, you'll have to change the IdentityPoolId, the region and the Bucket name.
In order to search for members inside the platform, change line 2 inside fetch.php with the IP of the instance, the username, password and database name for accessing the mySql database which can be found in wp-config.php.
You can use AWS's Route 53 for DNS management, as instructed in this guide. Once you get the nameservers, add them to your domain provider.
Follow this guide to install SSL certificates on your domain.
