Assembling Binary Machine Code

Operating `Modes`:

These determine the assumed/default size of instruction operands, and restricts which opcodes are available, and how they are used.

Modern operating systems, booted inside Real mode,

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

The following grammar is based on this EBNF specifications for EBNF meta-grammar:

ebnf            ::= [ global-desc ] { local-desc | rule | comment }

local-desc	::= '{' ? { any-character } ? '}'

global-desc	:: "{{" ? { any-character } ? "}}"

rule ::= identifier '::=' expression [ '.' ]

A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

Adapting the twelve-factor methodology for "Qubes-native" multi-VM applications: a preliminary sketch[^1]

Introduction

Virtualization is the conceptual technology on which modern services (server applications) are built. Whether an application happens to run on a fully- or para-virtualized VM[^2] or is containerized—or even runs on a “bare-metal” physical server after all—most modern services are designed in isolated, replicated, disposable components on commodity hardware.[^3] The [“twelve-factor methodology”][wiggins] (2011) is an influential articulation of the principles
