about this comic
Boot, Cluster, Rethink: A Field Guide to Firmware and Weird Operating Systems
my take on page 1
key idea
The talk links firmware, clusters, and alternative operating systems.
flip ↺
why this matters
Understanding all three layers explains how real machines start and scale.
flip ↺
p. 1 · 20
my take on page 2
key idea
Firmware is the first code a computer executes at power-on.
flip ↺
why this matters
Nothing else on a computer works until firmware finishes its job.
flip ↺
p. 2 · 20
my take on page 3
key idea
Legacy firmware is proprietary, slow, and opaque.
flip ↺
why this matters
Opaque firmware means you cannot verify what runs before your OS.
flip ↺
p. 3 · 20
my take on page 4
key idea
Coreboot is minimal open-source firmware.
flip ↺
why this matters
Open firmware lets you audit and trust the earliest code on your machine.
flip ↺
p. 4 · 20
my take on page 5
key idea
Coreboot separates hardware init from a swappable payload.
flip ↺
why this matters
This split lets one firmware base support many boot targets.
flip ↺
p. 5 · 20
my take on page 6
key idea
Minimal auditable firmware shrinks the attack surface.
flip ↺
why this matters
Attacks that run before the OS are the hardest to detect and remove.
flip ↺
p. 6 · 20
my take on page 7
key idea
Clusters need thousands of machines to boot identically and reliably.
flip ↺
why this matters
A boot flaw that is harmless once becomes catastrophic across ten thousand nodes.
flip ↺
p. 7 · 20
my take on page 8
key idea
Infrastructure automates the full lifecycle of many machines.
flip ↺
why this matters
Manual management does not scale to thousands of servers.
flip ↺
p. 8 · 20
my take on page 9
key idea
Open firmware makes fleet-wide boot control possible.
flip ↺
why this matters
Boot policy you can script is boot policy you can automate and audit.
flip ↺
p. 9 · 20
my take on page 10
key idea
A known-good boot state makes machines predictable.
flip ↺
why this matters
You cannot reliably debug or automate machines that start from unknown states.
flip ↺
p. 10 · 20
my take on page 11
key idea
Plan 9 deliberately redesigns Unix's foundations.
flip ↺
why this matters
Studying a clean redesign reveals which OS ideas were essential and which were accidental.
flip ↺
p. 11 · 20
my take on page 12
key idea
In Plan 9 almost everything is a file.
flip ↺
why this matters
A single uniform interface makes systems simpler to learn and compose.
flip ↺
p. 12 · 20
my take on page 13
key idea
Each process gets its own customizable namespace.
flip ↺
why this matters
Per-process namespaces enable clean isolation and flexible composition of resources.
flip ↺
p. 13 · 20
my take on page 14
key idea
Plan 9 makes remote resources look and act local.
flip ↺
why this matters
Network-transparent files make distributed systems far simpler to build.
flip ↺
p. 14 · 20
my take on page 15
key idea
Plan 9's file model fits distributed cluster computing well.
flip ↺
why this matters
A consistent model across machines reduces the complexity of managing clusters.
flip ↺
p. 15 · 20
my take on page 16
key idea
Firmware, clusters, and OS design meet in real deployments.
flip ↺
why this matters
Hard-won deployment experience is what ties these abstract ideas together.
flip ↺
p. 16 · 20
my take on page 17
key idea
Research OS ideas influence mainstream tools despite low adoption.
flip ↺
why this matters
Studying niche systems reveals ideas that later become industry standard.
flip ↺
p. 17 · 20
my take on page 18
key idea
Rethinking foundational layers exposes hidden assumptions.
flip ↺
why this matters
The biggest improvements often hide in layers no one thinks to question.
flip ↺
p. 18 · 20
my take on page 19
key idea
Hands-on entry points make these topics approachable.
flip ↺
why this matters
Experimenting cheaply and safely is the fastest way to understand systems.
flip ↺
p. 19 · 20
my take on page 20
key idea
The three topics are layers of one control problem.
flip ↺
why this matters
Seeing the whole stack as one story helps you reason about any system.
