System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Introduction

This is a public document offering a monetary bounty to writers who are willing to write a piece on Homeopathy in India. The bounty money is yours to keep. If you do not wish to keep it, I'll donate it to a charity of your choice.

Why

Welcome Cure is an Indian homeopathy startup that raised $6 million recently. I don't think that investors in India should be trusting their money with something that doesn't work and plays with the public's health. Consider this bounty as an incentive to do something about it.
