From Boot to HTTP: A Line-by-Line Analysis

A few years ago I did a talk about ToaruOS in which I traced through the system and explained how typing in a terminal worked at each layer. ToaruOS has changed a lot since then, and the slides from that talk have become outdated. Additionally, the level of detail to which a 40-minute talk can delve is limited, but an article can go much deeper. With the recent development of ToaruOS-NIH, a completely in-house distribution of ToaruOS with all code under the NCSA license, I figured it was time to approach that challenge again.


This article is a followup to my talk at Yelp, which itself was inspired by an article that posed the following question:

class Foo(object):
a = 1
f = Foo()
f.a = 3
g = Foo()
print g.a, f.a, Foo.a # 1 3 1
Foo.a = 4
h = Foo()
print g.a, f.a, h.a, Foo.a # 4 3 4 4
