Systematic Software Diagnostics


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.

The Dream of Quantum Software Diagnostics

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.

Visual Category Theory

The current full set in either PDF or paperback or both is available for purchase from Software Diagnostics Services

Download Sample Pages and Index

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.


Download Free Part 0

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.

Part 2 (ISBN-13: 978-1912636419) is currently available on Leanpub and Amazon Kindle Store. It covers duality, products, coproducts, biproducts, initial and terminal objects, pointed categories, matrix representation of morphisms, and monoids.

Part 4 (ISBN-13: 978-1912636433) is currently available on Leanpub and Amazon Kindle Store. It covers non-concrete categories, group objects, monoid, group, opposite, arrow, slice, and coslice categories, forgetful functors, monomorphisms, epimorphisms, and isomorphisms.

Part 6 (ISBN-13: 978-1912636457) is currently available on Leanpub and Amazon Kindle Store. It covers ideas that require a leap of abstraction: vertical and whisker compositions of natural transformations, identity and isomorphism of functors, equivalence, isomorphism, and adjoint equivalence of categories, functor and morphism categories, natural transformations as functors, representable functors, category of presheaves, Yoneda embedding and lemma. It also includes an index for parts 1 - 6.

General trace and log analysis patterns allow the application of uniform diagnostics and anomaly detection across diverse software environments. This 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. Pattern-oriented trace and log analysis is applicable to troubleshooting and debugging Windows, Mac OS X, Linux, FreeBSD, Android, iOS, z/OS, and any other possible computer platform, including networking and IoT. Its pattern catalog is a part of pattern-oriented software data analysis, diagnostics, anomaly detection, forensics, prognostics, root cause analysis, and debugging developed by Software Diagnostics Institute<. Also, the scope of applicability of such analysis patterns is much wider than just software execution artifacts or temporal data and now includes general data, narratives, text, and image analysis (space-like narratology). This reference reprints with corrections almost 200 patterns originally published in Memory Dump Analysis Anthology volumes 3 - 13 and Software Diagnostics Library. It also includes additional 5 analysis patterns from the forthcoming volume 14 bringing the total analysis pattern count to 201. Full-color diagrams accompany almost all pattern descriptions. The fourth edition includes 24 more patterns, updated classification, the bibliography, and the list of narratological and mathematical influences.

Introducing Diagnomicon

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.

Praise for the series:

I have been working with reversing, dumps, IAT, unpacking, etc. and I am one of the few at my workplace that like analyzing hangs and crashes. I always knew that I had more to learn. So I continuously look for more info. Many links directed me to dumpanalysis.org. Frankly speaking, its spartan/simple design made me question its seriousness. But after reading some articles, I immediately decided to order "Memory Dump Analysis Anthology". I have only read 100 pages so far. But I am stunned. It is such an amazing book. How the author refines/reconstructs the call stack, and finds useful information in the stack is incredible. I am enormously thankful for the effort that the author has put into making these books. They are very didactic even though the topic is a bit hard. It is a real treasure.

Exercises in Logging Style

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.
