To evaluate the value of msg.sender when using solidity/assembly's delegatecall:

We start out with 3 contracts:

pragma solidity ^0.5.7;

contract ScratchPadActions {
    event SenderActions(address contractAddress, address sender, address second);
    function relay(ScratchPad2 second) public returns (address) { 
        emit SenderActions(address(this), msg.sender, address(second));

SETH Examples

Setup

Need .sethrc for the blockchain you want to connect to. For this demo we'll be using dapp testnet and the setup-testnet.sh script from icetan. This script gets and sets some env variables for us:

• ETH_FROM
• ETH_PASSWORD
• ETH_KEYSTORE
• ETH_RPC_URL

Directions:

For the activities listed below, please create a gist on GitHub to capture your reflections for each of these 3 parts.

1. Read through this post from Red Pill Programming to get a sense of the different mindsets you'll want to consider in your new career: The Software Engineer Framework: 8 Ways to Become a Better Software Engineer.

   • Approximate reading time: 15 minutes
   • After reading, please write a reflection (4-6 sentences) on your takeaways from the post.

2. Mentioned in the first reading, the idea of a strong checklist is the focus in the second reading. Read through and/or listen to this interview with Atul Gawande (author of the Checklist Manifesto). It includes an excerpt from his book, which is optional reading.
