This training course is a combined, reformatted, improved, and modernized version of the two previous books Windows Debugging: Practical Foundations and x64 Windows Debugging: Practical Foundations, that drew inspiration from the original lectures we developed almost 18 years ago to train support and escalation engineers in debugging and crash dump analysis of memory dumps from Windows applications, services, and systems. At that time, when thinking about what material to deliver, we realized that a solid understanding of fundamentals like pointers is needed to analyze stack traces beyond a few WinDbg commands. Therefore, this book is not about bugs or debugging techniques but about the background knowledge everyone needs to start experimenting with WinDbg and learn from practical experience and read other advanced debugging books. This body of knowledge is what the author of this book possessed before starting memory dump analysis using WinDbg 18 years ago, which resulted in the number one debugging bestseller: multi-volume Memory Dump Analysis Anthology. Now, in retrospection, we see these practical foundations as relevant and necessary to acquire for beginners as they were 18 years ago because operating systems internals, assembly language, and compiler architecture haven't changed much in those years.

The book contains two separate sets of chapters and corresponding illustrations. They are named Chapter x86.NN and Chapter x64.NN respectively. The new format makes switching between and comparing x86 and x64 versions easy. There is some repetition of content due to the shared nature of x64 and x86 platforms. Both sets of chapters can be read independently. We included x86 chapters because many 3rd-party Windows applications are still 32-bit and executed in 32-bit compatibility mode on x64 Windows systems. The course consistently uses WinDbg (X86) for 32-bit examples and WinDbg (X64) for 64-bit examples. The book also has a larger format similar to other training courses from Software Diagnostics Services.

Almost 5 years have passed since the first edition of the combined training course that used the earlier version of Windows 10. Since then, we have also published "Practical Foundations of Linux Debugging, Disassembling, Reversing" and "Practical Foundations of ARM64 Linux Debugging, Disassembling, Reversing" books. At that time, we thought about revising our Windows course. Since then, Windows 11 appeared, and we also added Docker support for most of our Windows memory dump analysis courses. While working on the "Accelerated Windows Debugging 4D "course, we decided to make the second edition of Practical Foundations of Windows Debugging based on WinDbg from Windows 11 SDK and Visual Studio 2022 build tools and an optional Docker support for the exercise environment. We also changed the ":=" operator to "<-" in our pseudo-code for Intel disassembly syntax flavor to align with our recent Linux Practical Foundations books, which use "->" in pseudo-code for x64 AT&T disassembly syntax flavor and "<-" in pseudo-code for ARM64 disassembly syntax. All sample projects were recompiled, and many diagrams were redone for the new edition to reflect changes in code generation. WinDbg syntax and code highlighting were also improved. There are also minor additions for C++11 and C++20.

The book is useful for:

• Software technical support and escalation engineers
• Software engineers coming from managed code or JVM background
• Software testers
• Engineers coming from non-Wintel environments
• Windows C/C++ software engineers without assembly language background
• Security researchers without x86/x64 assembly language background
• Beginners learning Windows software reverse engineering techniques

This introductory training course can complement the more advanced course Accelerated Disassembly, Reconstruction and Reversing, Revised Edition. It may also help with advanced exercises in Accelerated Windows Memory Dump Analysis, Fifth Edition, Part 1, Revised, Process User Space and Accelerated Windows Memory Dump Analysis, Fifth Edition, Part 2, Revised, Kernel and Complete Spaces. This book can also be used as an Intel assembly language and Windows debugging supplement for relevant undergraduate-level courses.

Table of Contents

When we interact with a debugger, we use the so-called REPL, Read-Execute-Print-Loop (where we replace Eval in traditional REPL). We type some command, it is executed by a debugger engine against a memory dump, the results are printed, and we repeat. However, the results can be streamed for further processing, for example, to automate certain analysis patterns, for example, Structure Sheaves (as distributed logs), Region Profiles, and Region Clusters (we list recently added analysis patterns). In the background, the stream processing results are provided back to the debugger Print phase (or in parallel as a further diagnostic aid).

In the case of software traces and logs, streaming is a natural part of processing. But CoTraces fit into REPLS (processed results can also form Message Annotations), and generally, Diags.

REPLS is an architectural pattern, and it is now added to our catalog of software diagnostics architecture patterns.

Systematic Software Diagnostics attempts to unify various disorganized and fragmentary individual software diagnostic approaches for software construction and post-construction phases.

Initially, when working on software diagnostics foundations, we recognized the need for systematicity by including some of our books and training courses in the Systematic Software Fault Analysis Series. Over the following years, our many practical books became supplemented by theory and a series of seminars.

Now, after more than 15 years, coherent and complete theoretical, practical, and factual knowledge is systematically unified and ordered into pattern catalogs according to first principles after being integrated across individual observations as fully as possible at this time of the discipline development. In addition to systematicity, software diagnostics is also highly interdisciplinary and systemic, crossing boundaries of other disciplines. Its fundamental methodology is a pattern-oriented analysis of artifacts. Every artifact is considered a trace, log, text, and narrative. Diagnostic analysis patterns, common recurrent analysis techniques and methods in specific contexts, organized into catalogs, are used to identify structural and behavioral patterns, common recurrent problems (sets of indicators, symptoms, signs) together with recommendations and possible solutions to apply in specific contexts.

Consider, for example, a typical diagnostic procedure called measurement. It is an analysis pattern itself applied to artifacts or used to generate other artifacts to which analysis patterns are applied. Systematic Software Diagnostics is equally applicable to software development processes where the same analysis patterns are applied to development artifacts, repositories, documentation, management operations, monitoring, team structure, and dynamics. Even a diagnostic analysis is considered an artifact to apply analysis patterns. Where Systematic Software Diagnostic overlaps with other development and engineering activities, it offers additional pattern languages for software data analysis, troubleshooting, debugging, root cause analysis, performance analysis, writing tools, software and memory forensics, memory dump analysis, network trace analysis, static and dynamic malware analysis, reversing, vulnerability analysis, software internals, and cloud computing.

This training course is a Linux ARM64 (A64) version of the previous Practical Foundations of Linux Debugging, Disassembly, Reversing book. It also complements Accelerated Linux Core Dump Analysis training course.

The book skeleton is the same as its x64 Linux predecessor, but the content was revised entirely because of a different Linux distribution and CPU architecture.

The course is useful for:

• Software support and escalation engineers, cloud security engineers, SRE, and DevSecOps
• Software engineers coming from JVM background
• Software testers
• Engineers coming from non-Linux environments, for example, Windows or Mac OS X
• Engineers coming from non-ARM environments, for example, x86/x64
• Linux C/C++ software engineers without assembly language background
• Security researchers without assembly language background
• Beginners learning Linux software reverse engineering techniques

This book is a revised edition of the original Accelerated Windows Software Trace Analysis training course. General trace and log analysis pattern language covers any execution artifact from a small debugging trace to a distributed log with billions of messages from hundreds of computers, thousands of software components, threads, and processes. It also allows the application of uniform diagnostics and anomaly detection across diverse software environments, troubleshooting and debugging Windows, Mac OS X, Linux, Android, iOS, and any other possible computer platform including networking and IoT. Part 1 covers fundamentals and explains more than 60 basic trace and log analysis patterns, which are now cross-referenced in this improved and less Windows-centric edition. It can also serve as a reference.

Revised slides from the book

We are adding quantum computing to our research agenda now by coining "Quantum Software Diagnostics" as a way to analyze different parts of very large software execution artifacts simultaneously, make sense of entire software traces and logs, and predict software behavior (software prognostics). It contains two adjoint phrases centered around Software: left adjoint Quantum Software Diagnostics and right adjoint Quantum Software Diagnostics. The former is about diagnosing quantum software, and the latter is about applying quantum methods to problems of software diagnostics.

In June 2009, we wrote in Memory Dump Analysis Anthology, Volume 3:

"Quantum computation, quantum memory, and quantum information are hot topics today. Unfortunately, quantum mechanics forbids perfect (ideal) memory dumps due to the so-called no-cloning theorem. Still, it is possible to get inconsistent (imperfect) memory dumps, and perfect memory dumps can be made from quantum computer simulators. The analysis of quantum memory snapshots is the domain of Quantum Memoretics."

Since then, we have added traces and logs, text, narrative, data to our pattern-oriented analysis approach. Now we broaden the application of quantum ideas and algorithms and add quantum information processing to our decades' long interest in contemporary mathematics, quantum theory foundations and applications to various domains, logic, semiotics, categories, and recently, in ML/AI, unconventional computing, conceptual mathematics, topos theory, and functional programming.

Concepts from category theory were used as metaphors for some trace and log analysis patterns (see Mathematical Concepts in Software Diagnostics and Software Data Analysis) and also as a foundation of software diagnostics (see Categorical Foundations of Software Diagnostics) as a part of Theoretical Software Diagnostics. However, category theory abstractions are very challenging to apprehend correctly, require a steep learning curve for non-mathematicians, and, for people with traditional naïve set theory education, a paradigm shift in thinking. The book utilizes a novel approach to teach category theory and abstract mathematics in general by using LEGO® bricks. This method was discovered when applying the same technique to teach machine learning, its data structures and algorithms, particularly directed graphs.

Part 0 (ISBN-13: 978-1912636396) covers universe and sets, set-builder notation, set membership, set inclusion, subsets as members, membership vs. subset, powerset, relations, functions, domain, codomain, range, injection, surjection, bijection, product, union, intersection, set difference, symmetric set difference, sets of functions, function composition, inverse functions.

In order to facilitate earlier adoption and feedback, the book was split into small manageable parts. Part 1 (ISBN-13: 978-1912636402) is currently available on Leanpub and Amazon Kindle Store. It covers the definition of categories, arrows, the composition and associativity of arrows, retracts, equivalence, covariant and contravariant functors, natural transformations, and 2-categories.

Book Sample

CoPart 1 (ISBN-13: 978-1912636815) is a dual complement to Visual Category Theory Brick by Brick, Part 1. It is currently available on Leanpub and Amazon Kindle Store. The original series translated abstract categorical concepts into the language of LEGO® bricks, and the CoPart series implement the opposite way of translating brick constructions to the standard diagram language of category theory that should benefit comprehension of definitions. Since usual categorical diagrams are black and white and occupy less space on paper, CoParts include additional color-enhanced diagrams in the spirit of brick constructions when arrow source and target parts use different colors. These CoParts from CoSeries (named after opposite categories with reversed arrows) keep the same 1-to-1 page correspondence between Parts and CoParts. Page layout is also similar: location of explanatory notes (written using standard mathematical notation) is the same — only bricks are replaced by letters, dots, and arrows. Therefore, this CoSeries can be used independently from the original series or together.

Table of Contents

Recently we noticed the increased usage of -nomicon Ancient Greek suffix that signifies books with some length, prominence within, and importance to some field of knowledge, or simply, "pertaining to rules," or "book of." It is a combination of nomos (νόμος, law), and icon (εἰκών eikon, image). At the same time, We've been using the Memory Dump Analysis Anthology phrase for more than 15 years and used to abbreviate it as MDAA. Over the years, this massive book sequence accumulated almost 5,000 pages and now includes writing on trace and log analysis and diagnostics in general. We found that the word Diagnomicon was never used before (perhaps we even coined it), and we took it as an extra MDAA book name. We also acquired the Diagnomicon.com domain that currently points to Software Diagnostics Institute, but we plan to make it a separate website soon dedicated to marketing the MDAA collection entirely.

Table of Contents

Years ago, I bought the book in Russia whose title is “Literature of Formal Constraints: Form and Games from Antiquity to Present Days” by Tatiana Bonch-Osmolovskaya if I translate it to English. Such literary techniques and patterns are also known under the term constrained writing. The reason why this book caught my attention in the bookshop is that at that time, I was developing software narratology as a foundation of trace and log analysis patterns. So, I planned to mine it for pattern writing. However, due to other pressures, I put it in a reading list until very recently, when reading a preface to Exercises in Programming Style, Second Edition, by Cristina Videira Lopes (ISBN-13: 978-0367350208), I learned about the Oulipo movement (writing under constraints). I immediately realized that software traces and logs are software narratives under constraints. I plan to explore such constraints by providing creative examples of trace and log statements and messages. As a metanarrative template, I chose a variation of narrative from Exercises in Style book by Raymond Queneau:

The software narrator “S” is a rule-based system tracing process, and it notices a long-running process that had loaded hat.dll and got into resource contention difficulties with another process. Two hours later, the software narrator notices the same process and a debugger process that gives some advice regarding the functionality of an extra GUI button.

Another variation I chose is the frequent message found in logs on the “access denied” theme. Such constraints may be personal and organizational preferences and styles, programming language, execution environment, and technology stack limitations, different coding phases (development, maintenance, early vs. mature code), external constraints such as source code scope, tracing and logging configuration and rules, timing, the need for a quick debugging fix, or understanding program state and behavior.

In writing these exercises in tracing style, I also plan to reference trace and log analysis patterns where appropriate.

I add links to variations as soon as they are published. I also consider them a part of the modeling activities I do while working on the Writing Bad Code book.

This month, www.DumpAnalysis.org turns 15 (F). Initially, in March 2006, it started as Crash Dump Analysis and Debugging Forum (now frozen at https://www.dumpanalysis.org/forum/ where old posts are available). In August 2006, it became Crash Dump Analysis Blog, later moved to https://www.dumpanalysis.org/blog/ and renamed to Software Diagnostics Library as only posts about analysis patterns became added to it. When the blog was moved, the root URL (https://dumpanalysis.org/) became Crash Dump Analysis Portal, later renamed to Software Diagnostics Institute in 2012.
