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 started programming (in AmigaBASIC) when I was 10 years old. Nowadays, I'm most comfortable using Perl, C and JavaScript. I know Java and PHP too, but I can't really say I like them. I also know some Python, but not as much as I'd like.


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.


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:

Alas, this does not meet the 100,000+ messages/sec encryption requirement, at least not if the messages have different keys.

Sure you can do visual crypto without a computer. Just get some semitransparent graph paper and color in the squares. The resolution won't be too great, but you should be able to make some recognizable images.

One suggestion I'd like to make to the OP would be to unaccept the currently accepted answer for a while -- even though it IMO is the best one so far -- and see if anything better will turn up. Sometimes, prematurely accepting an answer may discourage other potential answerers from contributing their answers (or even from taking a look at the question in the first place).

@e-sushi: Yeah, the answers so far aren't too hot, but that's not really the question's fault. It could have good answers, and I suspect that there are people on this site who could write some, if they found this question and felt motivated to do so.

Ps. I just edited this question to try and make it little better focused and more likely to invite comprehensive answers based on expertise. Please feel free to improve it further, or to correct anything in my edit that you don't find appropriate. I also created the education tag, based on the corresponding tag on Mathematics SE.

better title, misc. copyedits, add paragraph asking for specific expertise, better tags

Honestly, I think this could be a good subjective question, and I don't think the closing reason quoted by @e-sushi really applies (as the question is really asking for answers based on expertise, not for purely personal opinions). That said, the current bunch of answers isn't particularly inspiring. I really wish someone would come up with at least one really good, comprehensive answer to set the proper tone here.
