Forthcoming Management Bits: An Anthology from Reductionist Manager

Being a software engineer, the author penetrated a software technical support department of a major software company rising to a management position. There he started collecting various management bits and tips promising everyone to write a management book. After moving back to engineering he became a director of several software research, education, publishing and software behavior analysis consultancy institutions including a museum. This book is an anthology of selected and edited blog posts from his Management Bits and Tips blog.

What this book has to do with the crash dump analysis then? Considering metaphorically an organization as a software machine, teams as processes and individuals as threads the author had applied his unique knowledge of software crashes and hangs to organizational project failures.

Museum of Debugging and Memory Dumps

This multi-dimensional museum shows exhibitions dedicated to the history of debugging, memory dump artifacts and art.

If you would like to donate an exhibit (for example, an old memory dump or a picture related to debugging) please use this page: http://www.dumpanalysis.org/contact. Any donations are greatly appreciated!

Crash and Hang Analysis Audit Service

Problem: You are not satisfied with a crash report.

Problem: Your critical issue is escalated to the VP level. Engineers analyze memory dumps and software traces. No definite conclusion so far. You want to be sure that nothing has been omitted from the analysis.

Problem: You analyze a system dump or a software trace. You need a second pair of eyes but don't want to send your memory dump due to your company security policies.

Resolution: DumpAnalysis.com analyzes your analysis and provides recommendations.

This new service comes in July - August, 2010. Prices will be announced soon.

Written by the founder of DumpAnalysis.org this book is not about bugs or debugging techniques but about background knowledge everyone needs to start experimenting with WinDbg, learn from practical experience and read other advanced debugging books. Solid understanding of fundamentals like pointers is needed to analyze stack traces beyond !analyze -v and lmv WinDbg commands. This is the book to help technical support and escalation engineers and Windows software testers without the knowledge of assembly language to master necessary prerequisites to understand and start debugging and crash dump analysis on Windows platforms. It doesn't require any specific knowledge, fills the gap and lowers the learning curve. The book is also useful for software engineers coming from managed code or Java background, engineers coming from non-Wintel environments, Windows C/C++ software engineers without assembly language background, security researchers and beginners learning Windows software disassembling and reverse engineering techniques. This book can also be used as Intel assembly language and Windows debugging supplement for relevant undergraduate level courses.

Praise for the book:

I am a C++/Windows developer and have been a Windows debugging enthusiast for quite a long time now. However, I have never been able to get a good and credible source of information with regards to the internals of debugging using WinDbg. Over the years, I have laid my hands on various sources that deal with Windows Debugging tools and debugging techniques. Every time I purchased a book or went through an online source, I was limited to confusing information that lead me to give up on this topic. Even reliable books that claimed to be the best in the market were nothing less than a colossal disappointment. However, recently when I came across "Windows Debugging: Practical Foundation" that was purchased by a friend of mine, I was sceptic but, nonetheless, decided to give it a chance. Trust me, although not perfect, the book has helped me a lot in learning more about windows internals and debugging techniques. I would like to extend my complements for writing a book that divulges details in a very concise yet clear manner.

CARE: Crash Analysis Report Environment

Welcome to the project CARE!

CARE means Crash Analysis Report Environment. It includes a pattern-driven debugger log analyzer and standards for structured audience-driven reports.

Please help to populate the database of stack traces by submitting your WinDbg output logs. You can use VBScript / WinDbg script to process all .DMP files on your hard drives: DebuggerLogs.zip. The archive contains VBScript file for x64 WinDbg (DebuggerLogs64.vbs) and for x86 WinDbg (DebuggerLogs.vbs) plus the very simple mode-independent WinDbg script (DebuggerLogs.wds). The WinDbg output is stored in dbgeng.log file.

Note: Please do not submit your crash dumps because the file size is limited to 2 MB and CARE system is currently being designed to analyze debugger logs only. If your log is bigger you can submit a zip file. If you have any problems please contact the administrator. Please do not expect any crash analysis response for your logs. The submittal is currently for internal CARE database population only and not for the pattern analysis of your computer memory.
