BlockChain

Hey Blockchain Hacker,   You can implement your solutions as user-facing apps (mobile apps or web apps) or as smart contracts (for the Ethereum blockchain or Hyperledger), or both.   If you choose to build a mobile app, we highly recommend using Toshi. , built by the awesome folks at Coinbase. It provides a built-in integration with Ethereum. Every user has an ETH wallet, and you can write JavaScript code to easily transfer money between users and the app.   If you choose to build a web app, you may find it useful to interface with smart contracts with  web3.js. (if your smart contracts are running on Ethereum), or with Fabric Client SDK (if your smart contracts are running on Hyperledger).   To code smart contracts, we recommend  Truffle for Ethereum (code in the Solidity language), and  Fabric SDK  for Hyperledger (code in GoLang).

Radio Garden

Explore live radio by rotating the globe
by ISRO
LIVE RADIO

How it works??

The radio garden depends upon its radio partners. There are more than 8000 radio stations who have enlisted as of now and expected to be increasing.
Imagine the Cricket match happening in Mumbai, India. The video will be taken live and they will be send to the broadcasting server. The server is connected to the Internet and it will broadcast the match all over the globe through satellites. The receiver, (TV) can watch the match by tuning the correct frequency (Channel in the TV)
The same principle applies here. The radio stations all over the world will send it’s data to the radio garden. They will organise everything and broadcast it all over the world. User can select any radio and c listen to them instantly. Any geostationary satellite (communication satellite) can do this job. The specific details of satellites will not be revealed.

Thanks!
