Line 1: Line 1:
Although not strictly for forensic purposes, '''visualization tools''' such as the ones discussed here can be very useful for visualizing large data sets. As forensic practitioners need to process more and more data, it is likely that some of the techniques implemented by these tools will need to be adopted.

If you are building forensic tools, you probably want to start with one of these:
+
; Java and Swing
+
: Advantage: Portable and lots of good documentation out there.
+
: Disadvantage: Programs are a bit verbose, and only offers about 1/2 the performance of C
+
 
+
; Python with tkinter
+
: Advantage: Portable
+
: Disadvantage: Python is one of the slowest modern languages around.
+
 
+
; Python with wxWidgets
+
: Advantage: Portable and a better development environment than tkiner
+
: Disadvantage: wxWidgets is not installed by default, so you'll need to get it installed. Not as well documented as Tkinter
+
 
+
; [http://processing.org processing.org]
+
: Advantage: Programming language specifically developed for visualization; compiles to java byte code
+
: Disadvantage: Very oddball
+
 
+
; JavaFX - Java's version of Flash

How are they more valuable than mount -o ro?

To add value, wouldn't a write-blocker need to be infallible, then *proven* to be infallible? (That is, proven to be as such, within the margin demonstrated by proving compliance with RTCA/DO-178B using Criticality Level 1). johnc 17:49, 28 December 2011 (PST)
