if depth[i,j] > 900:
final[i,j] = depth[i,j]

# About #
#########
# This script uses a Raspberry Pi to sense for the presense or absense of water.
# If there is water, an email is sent and a buzzer goes off.
# When it's dry again, another email is sent, and the buzzer turns off.

System Design Cheatsheet

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

Basic Steps

  • 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?
