I'm not really a cryptographer, I just play one on the Internet. ;-)

I'm a PhD student in biomathematics, working on stochastic individual-based models of evolution in spatially structured populations. My other interests include cryptography, programming games and puzzles, photography and graphic design.


I'm the main author and maintainer of the Stack Overflow Unofficial Patch (SOUP), a user script for browsers with GreaseMonkey-compatible user script support (Firefox, Chrome, Opera, possibly Safari) that fixes or works around a number of outstanding issues with the Stack Exchange user interface.

I tend to answer a lot more questions than I ask. Some answers I'm rather proud of:

CC-Zero Please consider any (original) code I post to Stack Overflow and other Stack Exchange sites to be released under CC-Zero unless stated otherwise. You may do whatever you want with it and don't have to credit me in any way, although of course that would be nice.

comment Testing a steganalysis technique on realistic data
@Layla: I just tried to do that myself, but feel free to change anything you want (especially if you feel I introduced any inaccuracies). It's your question, after all.

rephrase to make it look less like a "reference request"

comment Testing a steganalysis technique on realistic data
I'm not sure if this question really qualifies as a "reference recommendation" in the sense discussed at the meta post @e-sushi linked to. Even if it does, though, rephrasing it e.g. as "How can I test the effectiveness of my new image steganalysis technique on realistic data?" should make it on topic here.
