Whisper

Ephemeral, geo-location based semi-anonymous communication

• Messages can be loud or quiet
• Loud messages have a larger radius and die quicker
• Quiet messages have a smaller radius and last longer

Screenshot

Usage

$ git clone git@github.com:tlhunter/whisper.git
$ cd whisper
$ npm install
$ ./server.js 8000

Technologies

• REDIS for storing messages
• Node.js for web server
• HTML5 Geolocation
• Socket.IO for Websockets

Data

Due to the expiring, small data size, and rate of access, REDIS seems the appropriate choice

• Latitude, Longitude, Geohash
• Message (limit 255 characters)
• Size
• Date
• IP Address (for spam purposes, might just store MD5(IP+SALT) for anonymity)

Interface

This will be a webpage, very simple, works on mobile, uses HTML5 geolocation API

• Listing of visible messages
• Message input box
• Loudness slider
• Send button

Debugging

This chrome extension makes debugging a bit easier (so you don't have to walk around with a laptop): Manual Geolocation

TODO: This plugin no longer exists! How will we ever test Whisper!
