Posting to FaceBook feed using Graph API

Graph API was announced at F8 with a promise to dramatically simplify the FB API. I checked the read access over the new interface during the presentations and to my big surprise it worked flawlessly and from the first time. When I tried https://graph.facebook.com/facebook , JSON-formatted info about the FaceBook page was returned (as expected). Then I tried OAuth 2.0 way of accessing the API to post a message to the feed. And to my even bigger surprise it worked too! Here is what you need to do to access Graph API over OAuth: 1.

I think that Zeppelin is a nice collection of Solidity contracts that can be trusted. Let's use the StandardToken contract and use it as a parent class for our own RespectCoin contract. Step 2. Create RespectCoin contract and store it in "contracts/RespectCoin.sol" file pragma solidity ^0.4.4; import "../node_modules/zeppelin-solidity/contracts/token/StandardToken.sol"; /** * @title RespectCoin * @dev ERC20 Token example, where all tokens are pre-assigned to th e creator. * Note they can later distribute these tokens as they wish using `transfer` and other * `StandardToken` functions. */ contract RespectCoin is StandardToken { string public constant name = ...
