General Abnormal Patterns of Structure and Behavior (Part 0)

Tuesday, January 29th, 2013

Memory Analysis Patterns (MAPs) including memory dump, malware, software trace (TAPs), and other patterns and pattern catalogs from Software Diagnostics Institute form the very rich semantic network. Now it is possible (by using a metaphorical bijection) to create a catalog of General Patterns of Abnormal Structure and Behaviour including software, hardware, biological behavior including animal (ethology) and human behavior, sociological and historical behavior including economics, business and finance, ethics and law, and even behavior of chemical and physical systems. Such “GAPs of Structure and Behavior” may include wait chains, spikes, deadlocks, etc. We provide more specific examples in the forthcoming parts. So we are a few steps closer to realization of my old dangerous idea of a parameterized science of universal memory dumps by the so called science files or might event a general diagnostics discipline.

Analytic Memory Dump - A Mathematical Definition

Friday, September 28th, 2012

The previous mathematical definition of memory dump is for raw memory dumps. They are not really useful because they require symbol files. Each symbol file entry conceptually is a correspondence between a memory address and a direct sum or product of letters from some alphabet:

00000000`76e82c40: kernel32!WaitForMultipleObjectsExImplementation

So we propose an analytical definition of a memory dump as a direct sum of disjoint memory areas Mt taken during some time interval (t0, …, tn) where we replace stk having values from Z2 with Stq having values from Zp and cardinality of Zp depending on a platform (32, 64, etc) plus a symbolic description Di for each Stq with cardinality of ”i” set sufficient enough to accommodate the largest symbolic name:

M = Mt where Mt = ∑(Stq+Di)

or simply

M = (Stq+Di)

This can be visualized as a linear memory space such as a virtual memory space when symbol files are applied to modules one after another. However, all this is not necessary, as a symbol from a virtual address can also be mapped to a physical address if necessary. Di, in fact, refers to any symbolic description.

Facets of Systems Science

Monday, September 17th, 2012

If you liked An Introduction to General Systems Thinking book then you really need this comprehensive introduction which is more formal. Don’t be overwhelmed by the number of pages, you only need to read part 1, the first 218 pages as the rest is a collection of articles you can read selectively later on. For me one of the great features was the coverage of systems literature including some mathematical treatment books (including category theory in addition to famous Rosen’s books such as Anticipatory Systems). I also liked the discussion of critics of general systems theory that points to the fact that it should be called general systems-theory not general-systems theory. Highly recommended.

An Introduction to General Systems Thinking

Tuesday, August 28th, 2012

This book I bought more than 5 years ago after I recognized that systems approach was needed for memory dump analysis. However, I read it only recently while preparing to talk on systemic software diagnostics. While reading I realized that I already applied some systems theory ideas, for example, about isomorphism of disciplines as systems (which I named as metaphorical bijection): from literary narratology to software narratology and from that to network trace analysis. So if you are interested in systems either computer software ones or human organizational then I would greatly recommend this book as an introduction. The recommended literature in exercises is also useful.
