I showed this artwork to many people and they responded that they didn’t understand or hope one day they would understand. Only one guy (a professional manager) responded positively with understanding. What I think is that real art can be interpreted in many ways. So I kindly await your criticism.

PS. This Computicart (Computical Art) work was inspired by a pet parrot at home. I’ve been observing its behaviour for more than 6 months and tried to discern a few patterns. Its name is KiKi (not related to Ki* functions).

Training testimonials:

I would like to thank you and recommend your training. I think that the “Accelerated Windows Memory Dump Analysis” training is a pin-point, well taught training. I think it’s the leading training in the dump analysis area and I’ve enjoyed it, the books and materials are very detailed and well written and Dmitry answered all of the needed question. In addition after the training Dmitry sent a PDF with written answers and more information about the questions that were asked. I will give this training 5/5. Thank you Dmitry.

Second Eye (or sometimes a stronger variant “second pair of eyes”) - another engineer you typically need when you don’t see anything useful in a memory dump, software trace or source code for problem resolution purposes. You are anxious to recommend something useful.

Examples: Don’t see anything in this huge trace. I need a second eye.

Presentation Software Trace and Memory Dump Analysis: Patterns, Tools, Processes and Best Practices from E2E Virtualization Conference (13th of May, 2011) is available for download:

http://www.dumpanalysis.com/STMDA-materials

- Dmitry Vostokov @ DumpAnalysis.org + TraceAnalysis.org -

Very simple methodology summarized in just 3 words applicable to any problem solving domain and its activities including software troubleshooting and debugging:

Artifacts. Checklists. Patterns.

As an example of checklists and patterns please see these 3 presentations related to memory dump and software trace artifacts:

Introduction to Pattern-Driven Software Problem Solving

Fundamentals of Complete Crash and Hang Memory Dump Analysis

Pattern-Driven Memory Dump Analysis 

I’m now working on a detailed presentation of this methodology. 

- Dmitry Vostokov @ DumpAnalysis.org + TraceAnalysis.org -

Imagine a pattern-driven crash analysis report (car) when you need it: at the very moment of a crash, just in time! And the car drives you to a problem resolution. Imagine also a periodic pattern-driven just-in-time memory space analysis (JIT MSA) that provides you instant intelligent reports on what’s going on inside memory while your application, service or system is running! This is a forthcoming optional client side part of CARE (Crash Analysis Report Environment) which is being developed by Memory Dump Analysis Services engineering team under the leadership of Alexey Golikov. Combined with generative debugging techniques both client and server parts form a complete unique enterprise crash and hang analysis solution suitable for development and production environments. Stay tuned for further exciting updates.

PS. The car drives on a road to the first fault software problem solving.

Finally, after the numerous delays, the first Windows Debugging Notebook is almost ready for publication by the end of this month with a new cover and a foreword written by Mario Hewardt, the author of Advanced Windows Debugging and Advanced .NET Debugging books:

It is the first notebook because we have decided to split it into 3 different memory space volumes and one additional overview volume for concepts and tools:

- Windows Debugging Notebook: Essential User Space WinDbg Commands (ISBN: 978-1906717001 and 978-0955832857)
- Windows Debugging Notebook: Essential Kernel Space WinDbg Commands (ISBN: 978-1908043146)
- Windows Debugging Notebook: Essential Managed Space WinDbg .NET Commands (ISBN: 978-1908043153)
- Windows Debugging Notebook: Essential Concepts and Tools (ISBN: 978-1908043160)

On a bookshelf you would be able to distinguish between the first 3 volumes by a 3 color spine stripe with an appropriate check on it: red for kernel, blue for user, and green for managed space.

The Table of Contents has been changed too.

“… he who has not been in” support “does not know what” debugging “is.”

Attributed to Leo Tolstoy, by Adam Ulam, The Bolsheviks

- Dmitry Vostokov @ DumpAnalysis.org + TraceAnalysis.org -

Because the number of software trace patterns is growing I’m starting another checklist in addition to memory dump analysis checklist. The goal is to help experienced engineers not to miss any important information. The checklist doesn’t prescribe any specific steps, just lists all possible points to double check when looking at a software trace. Of course, it is not complete at the moment and any suggestions are welcome. This post will be modified on the ongoing basis.

General:

• Check overall trace time delta
• Check no trace metafile message density
• Check whether a trace is a multi-part or a circular
• Check for basic facts and the story (software narrative)
• Check for any exceptions, non-false positive errors and periodic errors
• Check for significant events
• Check for discontinuities in the time domain
• Check for message current and acceleration in the frequency domain

- Dmitry Vostokov @ DumpAnalysis.org + TraceAnalysis.org -

The first Webinar to start an in-depth discussion of pattern-driven software troubleshooting, debugging and maintenance:

Date: 25th of March 2011
Time: 18:30 (GMT) 14:30 (EST) 11:30 (PST)

Learning from Philip Marlowe, a detective:

“I like you,” she said suddenly. “You believe in miracles.”

Raymond Chandler, The Big Sleep

Do you believe in miracles from a driver modifying an arbitrary user space? Or in a miracle of suddenly disappearing software incidents?

Resolution rush - The rush of software technical support and maintenance engineers to provide the resolution to a suddenly escalated incident.

Examples: After it crashed 3 times in a row at the customer site our VP was called and we all got the resolution rush.

- Dmitry Vostokov @ DumpAnalysis.org + TraceAnalysis.org -

Working for more than 7 years in technical support environment I found that many support incidents were resolved more easily by abductive reasoning than by induction and deduction practiced by Sherlock Holmes and observed by Dr. Watson. Abduction as a way to build an incident theory to advance in problem resolution was practiced by a USA colleague of Holmes: Philip Marlowe. Because technical support is less detached from customers (”the world”) when compared to software engineering departments I see the way of Marlowe as more natural. Of course, from time to time the way of Holmes is also appropriate. All depends on a support case. I found that abductive reasoning is also appropriate for memory dump and software trace analysis where “leaps of faith” are necessary because of insufficient information. Such leaps of abduction actually happen all the time when analysts give troubleshooting advice based on patterns.

I plan to write more about the 3rd way of reasoning after I finish reading two Raymond Chandler’s novels and a few other inference, causality and explanation books I mention later: The Big Sleep & Farewell, My Lovely (Modern Library).

I’m grateful for Clive Gamble for pointing this way out in his book Archaeology: The Basics

With the new year starts the new initiative to integrate traditional multidisciplinary debugging approaches and methodologies with multiplatform pattern-driven software problem solving, unified debugging patterns, best practices in memory dump analysis and software tracing, computer security, economics, and the new emerging trends I’m going to write about during this year.
