Thoughts, musings, knowledge, etc. about digital forensics. As well as how computer science, IT (information technology) and IS (information security) relate.
Up until now, this thread of posts has been rather theoretical, talking about Turing machines, etc. the only time there was some source code was for showing a program that can print out a description of itself (its source code).
Well, one problem with the self-replication method for getting a copy of a program’s description is [...]
In this post I’ll cover the proof of the Recusion theorem (see Self Replicating Software - Part 1 - The Recursion Theorem).
The proof for the Recursion theorem is a constructive proof, meaning that a Turing Machine (TM) that can reference its own description is constructed. This proof was taken from Michael Sipser’s “An Introduction to [...]
This is the first in a multi part post about computing theory and self replicating software. This post assumes you have knowledge and understanding of a Turing Machine (abbreviated TM). If you aren’t familiar with Turing Machines (TMs) then you may want to take a look at the Wikipedia entry on the topic at http://en.wikipedia.org/wiki/Turing_machine [...]
Was doing some research on the structure of the Windows Recycle Bin, and found an interesting article over at Microsoft. It talks about the naming structure of the files in the Recycle Bin directories. In essence, the structure is as follows:
D<drive letter from original path><order #>.<original extension>
The field is a number signifying when the [...]
