By analogy with a security researcher profession I propose the new title of a software defect researcher as a unified profession combining relevant fields of security research, testing, debugging, memory dump analysis, software reverse engineering, construction and maintenance. At least I consider myself a software defect researcher. If you think you consider yourself too please write a comment to this post. Thank you in advance.

The digital version of the book is finally available:

x64 Windows Debugging: Practical Foundations

Paperback should be available in 1-2 weeks on Amazon and other stores. When working on the book I fixed errors in the previous x86 version. Errata file for it should be available tomorrow.

OpenTask plans to expand its Practical Foundations series and publish the following 2 books for the forthcoming Memory Dump Analysis Fundamentals certification (Unix track) being developed by Memory Analysis and Debugging Institute:

Sometimes I’m asked about a broad software engineering book to recommend for general memory dump analysis that covers software architecture, design methods and diagramming languages like UML, programming languages, concurrency, real-time issues and many other topics you need to know to have systems understanding that helps in problem identification and debugging. Here’s the book that I was fortunate to buy 4-5 years ago in a book shop and is a sheer pleasure to read:

Software Engineering for Real-Time Systems

Today I found that there even exists an OMG certification based on it:

http://www.omg.org/ocres/exam-info.htm

I might try later this summer.

The number of blog visits (excluding portal main page and other my blogs) was about 15,000 - 16,000 by the end of the last year and then it dropped to 13,000. I explain this as the fact that 5% - 10% of engineers were no longer interested in crash dumps and debugging due to layoffs. This month I see the number of visits exceeds 14,000 and this surely makes me more optimistic about the prospect of economic recovery:

- Dmitry Vostokov @ DumpAnalysis.org -

Previously announced memory dump analysis certification will have x86/x64-based tracks for Windows and Unix (including Linux / FreeBSD / Mac OS X). Each track consists of 3 exams, each having its own set of requirements and scope:

• Fundamentals of Memory Dump Analysis
• Intermediate Memory Dump Analysis
• Advanced Memory Dump Analysis

More information will be available later. The initiative is supported by OpenTask.

This is an example from the sample question set of the forthcoming memory dump analysis certification planned by Memory Analysis and Debugging Institute. You can reply to this post with your answers.

As soon as I wrote my review of the 2nd edition I found out that the 3rd edition was recently published and immediately bought it. I intend to read it from cover to cover again and publish my notes and comments in my reading notebook on Software Generalist blog. The new edition is also bundled with a companion CD.

Programming Language Pragmatics, Third Edition

Hope in one of subsequent editions the author includes my Riemann Programming Language :-) 

- Dmitry Vostokov @ DumpAnalysis.org -

Every debugging engineer needs to know how the code is interpreted or compiled. Debugging complex problems or doing memory analysis on general-purpose operating systems often requires understanding the syntax and semantics of several programming languages and their run-time support. The knowledge of optimization techniques is also important for low-level debugging when the source code is not available. The following book provides an overview of all important concepts and discusses almost 50 languages. I read the first edition 6 years ago and I liked it so much that I’m now reading the second edition.

Programming Language Pragmatics, Second Edition

Noticed today on Amazon that my book becomes more expensive after being used:

- Dmitry Vostokov @ DumpAnalysis.org -

Listening to étude No. 1 in C major written by Frédéric Chopin (Op. 10) an idea came to me about writing 16 debugging études (ISBN: 978-1906717575). It is surprising that there are many programming études out there but there are no debugging ones. Stay tuned and be in touch with this blog.

Draft definition:

Debugging étude is a composition of software with intentional defects (bugs) of considerable difficulty to find and fix, designed to provide practice material to perfect debugging techniques and problem-solving skills.

The idea actually came to me long time ago to create some sort of debugging excersises for training purposes.

I very proud to announce that after 3 weeks of final work the book has been released in both paperback and PDF format. In a week or so it should also appear on Amazon and other booksellers around the world. The book information and how to buy it can be found on the portal:

Publishing my old CV and salary expectations damaged my memory and yesterday night I experienced a dream where a courier arrived to my office. I opened a packet and saw an A4 plastic card with a cover displaying a VIP job offer from one company the name of which I cannot disclose here. The plastic job offer card also had 2 buttons: accept an offer and decline an offer. To the left of the buttons there was a picture of a tiger: I used to play with 2 x 2 tiger puzzle with my 2 year old son before that night… When I woke up the dream was so real that I searched around for that card

The analogy between learning a complex tool with its own language and a foreign natural language has been developed further after the release of WinDbg Learning Cards and finally culminated in “WinDbg In Use” book series with the first book to be published during the 1st quarter of 2009:

• Title: WinDbg In Use: Debugging Exercises (Elementary and Intermediate Level)
• Author: Dmitry Vostokov
• Publisher: Opentask (15 March 2009)
• Language: English
• Product Dimensions: 23.5 x 19.1
• ISBN-13: 978-1-906717-50-6
• Paperback: 200 pages
• Book Annotation: Includes 60 programmed exercises from real life debugging and crash dump analysis scenarios and multiple-choice questions with full answers, comments and suggestions for further reading.

Some example exercises will be published on this blog from time to time. I also plan a corresponding column in the forthcoming Debugged! magazine.

OpenTask publishes the following sequel to Resume and CV book:

Title: Salary Figures: A Codebook of Expectations
Author: Dmitry Vostokov
ISBN-13: 978-1906717469
Paperback: 100 pages (1 January 2009)
Product Dimensions: 20.3 x 12.7
Book Annotation: After publishing Curriculum Vitae as a book the author started receiving e-mails asking for his salary expectation. Being shy to discuss such matters openly he devised a codebook of salaries. Now everyone could answer a question about his or her salary expectations by referring to specific page. Also colleagues and friends could say to each other: “I’m still on page X” or “Last month I turned the page Y over”. The last 10 pages of the codebook specify various perks. The response template to the question of salary expectations is: “My salary expectation is on page Z plus benefits listed on pages N and M”. (*) X,Y,Z,N,M are page numbers from 3 to 100. Good luck with job hunting

Typeset in Chilling font the book is suitable for wide salary ranges, from 1,000 to 1,000,000.
