Contemplating Crash Dumps in Chinese

Thursday, July 29th, 2010

Sometimes I accidentally use du WinDbg command (to interpret memory as Unicode) instead of da (to interpret memory as ASCII):

0:000> db 07329f28 l20
07329f28  68 69 64 70 6e 73 74 3d-26 74 78 74 74 6f 3d 26  hidpnst=&txtto=&
07329f38  74 78 74 63 63 3d 26 74-78 74 62 63 63 3d 26 74  txtcc=&txtbcc=&t

0:000> da 07329f28 l20
07329f28  "hidpnst=&txtto=&txtcc=&txtbcc=&t"

0:000> du 07329f28 l10
07329f28  "楨灤獮㵴琦瑸潴.硴捴㵣琦瑸换㵣琦"

This time I tried to get extra hidden meaning from a process dump taken after the process suffered a CPU spike by using Google translator and got this text (I put more lengthy Unicode sequence and removed some offensive words):

"Luan Xian Zhen Qi-bin 㵴 cisternae. Huasong 㵣 Qi, Qi-bin-bin for 㵣 pull 㵪 䕒 .. 䉉 Ya Hui material. Hong SHIKA King. Huajiayuyan nuts .. 䐰 〥 䅁 evil force.

From the translation I see previously hidden notions of gems, disease and evil forces :-)

The Meaning of 7

Saturday, March 20th, 2010

I already had an experience with The Mystical One and a few weeks ago I finally grasped yet another parallel between The Year of Dump Analysis (0x7DA or 0n2010) and the fact that I started doing computer memory dump analysis 7 years ago! The emphasis here is on “computer“; before that I’d been doing general memory dump analysis for decades.

Occult Debugging

Monday, December 15th, 2008

Once upon a time I was analyzing a memory dump and in the process become upset. I realized that the dump was vacuous and afterwards learnt that the customer forced the dump of a normal system with steady-state computational activities inside. At the same time computational precognition, the ability to see in advance what would happen with the system, always fascinated me from the very beginning of my memory dump analysis work. In computational precognition phrase, the word “computational” refers to computers and “precognition” refers to humans but this should not be the problem as the boundary between these two categories is not sharp and can be shifted in either direction. This is an opening of the new post series about investigation of occult, paranormal and supernatural in the realm of computable. In short, about psi-computation.
