# Hello, and welcome to makefile basics.
#
# You will learn why `make` is so great, and why, despite its "weird" syntax,
# it is actually a highly expressive, efficient, and powerful way to build
# programs.
#
# Once you're done here, go to
# http://www.gnu.org/software/make/manual/make.html
# to learn SOOOO much more.

Introduction

Distributed systems

• Distributed systems = Computers + relativity
• Different machines have different clocks, perception of time, and views of the state of the system
• Challenges: Communication failures, hardware failures, latency, bandwidth
• All computer systems today are distributed at some level (nature obeys relativity after all), the extent to which this nature is exposed depends on the loads put upon the system.
