ottodevs / StringToLower.sol
Created September 26, 2017 11:22 — forked from thomasmaclean/StringToLower.sol
Ethereum/Solidity toLower() equivalent, to transform strings to lowercase
pragma solidity ^0.4.11;
contract StringToLower {
function _toLower(string str) internal returns (string) {
bytes memory bStr = bytes(str);
bytes memory bLower = new bytes(bStr.length);
for (uint i = 0; i < bStr.length; i++) {
// Uppercase character...
if ((bStr[i] >= 65) && (bStr[i] <= 90)) {
// So we add 32 to make it lowercase

Local Kubernetes setup on macOS with minikube on VirtualBox

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!

(This is a brief summary of Ethereum's white paper)

Ethereum 101

What is Ethereum

Ethereum is a new cryptocurrency, like Bitcoin or Litecoin, that adds a number of new features. Most notably the inclusion of Agents (also known as Contracts); Independent Turing-complete programs that exist on the Ethereum blockchain. These Agents can receive Ether (Ethereum's currency) and other inputs, perform computations, hold balances, transfer Ether, and even activate other Agents.

Ethereum also attempts to fix some current issues with cryptocurenncy mining, such as rise of specialized hardware, large mining pools that aim to control the network, and the lack of reward for stale blocks, dissuading miners with weaker hardware.

Agents

Trustin's /etc/pf.conf for Mac OS X
# 1. Put this file to /etc/pf.conf
# 2. Install init boot scripts using IceFloor then - http://www.hanynet.com/icefloor/
# I tried to use IceFloor to configure everything but it didn't work very well.
# 3. Once done, you can confirm the rules were loaded with 'sudo pfctl -sr'
# 4. At System Preferences -> Security -> Firewall -> Firewall Options,
# check 'Block all incoming connections' to prevent annoying per-app dialogs.
