Dr. Watson’s Observational Patterns (Part 2)

Tuesday, February 9th, 2010

His [Sherlock Holmes] hands were invariably blotted with ink and stained with chemicals, […]

A Study in Scarlet, Part 1, 2: The Science of Deduction, page 19

Before I started memory dump analysis:

[…] how objectless was my [Dr. Watson] life, and how little there was to engage my attention.

A Study in Scarlet, Part 1, 2: The Science of Deduction, page 19

Most problem solvers are not polymaths:

His [Sherlock Holmes] ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing.

Dr. Watson’s Observational Patterns (Part 1)

Sunday, February 7th, 2010

Today I started reading complete stories of Sherlock Holmes using the nice hardcover illustrated edition I bought in a local bookshop for just 12 euro (I give an Amazon link here though):

Buy from Amazon

I plan to read 1,408 pages of this book during my lunch time. The aim is to learn from Dr. Watson. Here is a pattern he discovered:

‘Very interesting reading it might be made, too,’ remarked Sherlock Holmes, sticking a small piece of plaster over the prick on his finger. ‘I have to be careful,’ he continued, turning to me with a smile, ‘for I dabble with poisons a good deal.’ He held out his hand as he spoke, and I [Dr. Watson] noticed that it was all mottled over with similar pieces of plaster, and discoloured with strong acids.

A Study in Scarlet, Part 1, 1: Mr. Sherlock Holmes, page 17 

I also noticed that Holmes analyzes dumps not too often but keeps his mouth shut like me for some time after seeing things there: 

I [Sherlock Holmes] get in the dumps at times, and don’t open my mouth for days on end.

A Study in Scarlet, Part 1, 1: Mr. Sherlock Holmes, page 17

Important trait of a memory dump analyst:

I [Dr. Watson] am extremely lazy.

Reasoning with a Bug

Sunday, January 31st, 2010

If those bugs had been around for hundreds of millions of years before evolution climbed mount improbable to design human species does it mean that software bugs came before intelligent software? :-)

Bugtation No.110

Sunday, January 31st, 2010

Debugging at large. Remember those bugs from The Day Earth Stood Still movie that were nicely deactivated at once? Remember Nobel Laureate Professor Barnhardt was threading with Klaatu over the correct version of General Relativity on a blackboard and then at once realized that he was talking to an alien? His next phrase was the one that I repeat every day (and I also listen to Bach every day):

“I have so many questions to ask” this memory dump.

Bug-sistential and Bug-sistentialism (Debugging Slang, Part 6)

Bug-sistential - pertaining to existing bugs
Bug-sistentialism - a pessimistic outlook about the existence of bugs

Crash, Core and Memory Dumps in Science Fiction and Fantasy (Part 1)

Sunday, January 10th, 2010

Being an aspiring SF delayed-writer I was curious about the usage of memory dump concept in science fiction. Here’s a selection of sentence fragments that give some picture (a few are from fiction not SF) and I plan to analyze it further in another part.

Ars Recordatio

Saturday, December 5th, 2009

The art of DA+TA analysis now acquires a Latin name: Ars Recordatio (from Latin recordatio: recollection, memory, recall and ars (artis): art, skill, method, technique, knowledge, method, science, way, conduct, character). Other variations I rejected, Ars Memoria, Ars Indicium and Ars Animus, are either widely used in a different sense or presuppose some kind of intelligence inside memory dumps and traces (animus).

BoBo Address (Debugging Slang, Part 4)

Thursday, November 12th, 2009
bobo address - an address a system will definitely crash at, given an opportunity

Examples: bad0b0b0, 00000000

- Dmitry Vostokov @ DumpAnalysis.org -

BAD0B0B0 Address: Childhood Memories

Thursday, November 12th, 2009

The system crashes at it (Google search shows 164,000 hits). Notice the second part “b0b0″ after “bad”. For my eyes (I wear glasses) it is “bobo” – that was my mother telling me when I was a child and I was about to touch a hot or sharp object.

Bad! Bo-bo!

Was the address value designed intentionally or it is just a coincidence?

DNA and RNA of Ruptured Computation

Friday, October 23rd, 2009

First, I introduce the notion of a ruptured computation that is a relaunched, restarted or resumed process from a checkpoint after a rupture in its fabric, for example, crash, hang, spike and leak forcing termination. DNA can be an abbreviation of a Dump of Nasty Application or Double-ruptures of Nasty Application but I got an enlightenment spike in my head recently after recognizing that C, H, S and L are 4 DNA bases: Crash, Hang, Spike and Leak. Do you see a parallel with the real DNA and its 4 bases: A, T, G, C? Now a sample of a  ruptured computation DNA strand (imagine, we launch an application and it crashes, …, crashes, …, crashes, …, spikes, …, crashes, …, hangs, …) can be represented as: …CCCSCH… . What about its second strand? I’m in search of it now but in the mean time I introduce the second notion of RNA (Really Nasty Application or Ruptures of Nasty Application) that is just one strand of …CCCSCH… as needed (real RNA is mostly single-stranded).
