Hi and welcome to my Github page!

I am a former student Msc. RW/CSE ETH Zurich living in switzerland.

Selected Projects

• https://github.com/maede97/AutodiffPythonCpp: Automatic differentiation of a function written in python and code generation for C++.

minusminusenergy's Issues

build system to simplify installation process

Installation script: startup.sh

• git clone
• cronjob
• db setup
• npm dependencies

Run script: run.sh

• npm run dev

Voting system as reward

Implement a voting system that takes into account how many tokens a certain consumer has contributed to the total amount.

• More contributions = more voting weight
• some form of entry mask to bring new project ideas to the table

Bill Contract: payBill(uint toFond)

The payBill() function has a bug and reverts sometimes.

Error somewhere here:

// Check for open bill
require(this.hasBill(msg.sender),"sender needs bill");

uint tokenAmount = _tokenContract.balanceOf(msg.sender);

// Check for sufficant tokens
require(toFond <= tokenAmount,"enough tokens to give to fond");

// Check for sufficant ehter
require(msg.value+toFond <= openBills[msg.sender].amount,"not sufficient ether");

// Reduce bill with tokens
openBills[msg.sender].amount -= tokenAmount-toFond;
_tokenContract.useToken(msg.sender);

// Pay ether to issuer
//openBills[msg.sender].issuer.transfer(openBills[msg.sender].amount);
//openBills[msg.sender].amount -= msg.value;
openBills[msg.sender].amount = 0;

// Pay ether to fond
_fondContract.invest.value(toFond)(msg.sender);

Frontend | Visualize saved energy

Implement a visualization that shows the consumer how much energy he saved.
This can be accomplished using relatable comparisons.
