Trace Analysis Patterns (Part 82)

Monday, May 5th, 2014

So far we have been discussing trace analysis patterns related to execution of a particular software version. However, software code changes and also its tracing and logging output: from large scale changes where components are replaced to small scale code refactoring affecting message structure and format. On a software narratological level this corresponds to a narrative about a software trace or log, it evolution. Such Meta Trace analysis pattern is different from Master Trace pattern where the latter is similar to what Metanarrative is usually meant in narratology: a master or grand idea - an expected trace if all functional requirements were correctly identified and implemented during software construction and non-functional ones are met during software execution.

MM=DD=YY

Wednesday, December 12th, 2012

To celebrate the last unique occurrence of 12.12.12 in this Century I created a Computical Art (Computicart) picture that uses minimalist software trace analysis diagrams I use for trace and log analysis patterns made even better for Accelerated Windows Software Trace Analysis course. The following diagram symbolizes several patterns. Suppose we trace personal or world events each year and form an Adjoint Thread with messages having DD=MM=YY timestamp invariant (or filter them). Then we clearly see a Discontinuity before the next Century with much bigger Time Delta than between such messages. Also these messages form a Periodic Message Block in relation to the full trace.

The Exception Point

Friday, November 23rd, 2012

This is the title of a novella to be published in Spring 2013 (ISBN: 978-1908043412). Book description:

Russia, 1908, June 30, 7:14 a.m., the court of Tsar Nicholas II is wiped out by an impact, an enormous explosion over St. Petersburg. In an ensuring chaos State Duma takes power over Imperial Russia changing the course of World history forever.

Forthcoming Transcript of Introduction to Software Narratology Webinar

Sunday, April 15th, 2012

In a week this short full color book should appear in online bookstores:

  • Title: Software Narratology: An Introduction to the Applied Science of Software Stories
  • Authors: Dmitry Vostokov, Memory Dump Analysis Services
  • Description: This is a transcript of Memory Dump Analysis Services Webinar about Software Narratology: an exciting new discipline and a field of research founded by DumpAnalysis.org. When software executes it gives us its stories in the form of UI events, software traces and logs. Such stories can be analyzed for their structure and patterns for troubleshooting, debugging and problem resolution purposes. Topics also include software narremes and their types, anticipatory software construction and software diagnostics.

Writing and Validation of Historical Narratives (Part 1)

Sunday, March 11th, 2012

Software narratological approach can be useful for writing, analyzing and validating historical narratives. Trace and event log messages play the role of historical events where process ids are assigned to particular historical institutions and their representatives. Threads serve the role of historical entities like persons. Modules play the role of shared ideologies. We already use this approach for writing history books.

This can also work on a different level such as analyzing a history of debugging as a sequence of troubleshooting and debugging stories. More on this later as I plan to provide concrete examples from history. For the time being please read how software narratology and memoretics (the study of memory snapshots) help fiction writers as well.

2012 is The Year of Software Trace Analysis

Saturday, December 17th, 2011

The number of software trace analysis patterns approaches the critical mass of 50 and we have decided to focus on software tracing and logging in the forthcoming year. Some books on tracing including Volume 7 of Memory Dump Analysis Anthology will be published by OpenTask during that year and our efforts will be to further advance software narratology, software trace linguistics, and software trace analysis in the context of memory dump analysis, generative debugging and modeling software behavior.

Crossdisciplinary Memoretics as Interdisciplinary Science

Wednesday, September 21st, 2011

Memoretics as a science of memory snapshots borrows many ideas from the following disciplines (the list is not exhaustive):

  • Troubleshooting and Debugging
  • Intelligence Analysis
  • Critical Thinking
  • Forensics
  • Linguistics
  • Archaeology
  • Psychoanalysis
  • History
  • Mathematics: Sets and Categories
  • Literary Criticism and Narratology

It also contributes many ideas back. The following diagram depicts such an interaction:

Intelligence Analysis Patterns (Part 0)

Sunday, May 22nd, 2011

Being deep into intelligence analysis while preparing for cyberwarfare memory dump analysis presentation I came to an idea of intelligence analysis patterns based on software trace analysis patterns and software narratology. Basically we consider intelligence data as pseudo-software trace messages with an additional probability field (column). Most of the patterns can be transferred and used immediately in intelligence analysis and I’m working on such a map. Because real software trace messages are quite certain (deterministic) where their sequences sometimes not (see, for example, Impossible Trace pattern) there are some unique patterns applicable only in intelligence analysis domain and I’m working on the first such pattern to introduce it in the next part.

Debugging in 2021: Trends for the Next Decade (Part 1)

Friday, December 17th, 2010

As the new decade is approaching (2011-2020) we would like to make a few previews and predictions:

- Increased complexity of software will bring more methods from biological, social sciences and humanities in addition to existing methods of automated debugging and computer science techniques

- Focus on first fault software problem solving (when aspect)

- Focus on pattern-driven software problem solving (how aspect)

- Fusion of debugging and malware analysis into a unified structural and behavioral pattern framework

- Visual debugging, memory and software trace visualization techniques

- Software maintenance certification

- Focus on domain-driven troubleshooting and debugging tools as a service (debugware TaaS)

- Focus on security issues related to memory dumps and software traces

- New scripting languages and programming language extensions for debugging

- The maturation of the science of memory snapshots and software traces (memoretics)

Imagining is not not limited to the above and more to come and explain in the forthcoming parts.

Trace Analysis Patterns (Part 31)

Wednesday, October 20th, 2010

The next pattern with the name borrowed from historiography is Layered Periodization. This periodization of software trace messages includes individual messages, then aggregated messages from threads, then processes as wholes and finally individual computers (in client-server or similar sense). This is best illustrated graphically.

Message layer:

Thread layer (different colors correspond to different TID):

Process layer (different colors correspond to different PID):

Please note that it is also possible to have a periodization based on modules, functions and individual messages but it might be complicated because different threads can enter the same module or function and here other patterns more appropriate like Activity Region, Characteristic Message Block, and Background and Foreground Components.

Patterns in History and Social Sciences: A New Approach

Monday, October 4th, 2010

I was thinking for some time about applying crash dump analysis patterns (later including software trace analysis patterns and more recently structural memory patterns) to History (one of my favourite study subjects) using metaphorical bijectionism as I tried before with the analysis of project failures. Yesterday I found this book that applies the perspective of patterns in natural sciences to History (according to its description):

Pattern and Repertoire in History

I plan to review the book and highlight the differences and similarities between the authors’ and mine patternist approaches to History.
