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?

require "dbus"

session_bus = DBus::SessionBus.instance

# Get the Pidgin Service
pidgin_dbus = session_bus.service("im.pidgin.purple.PurpleService")

# Get the object from this service
