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:

comment Tool that will do a circular blur/convolution
@jozxyqk: You could always try installing it with alien. Mind you, I've never tried that, so use it at your own risk. It might work, or it might not.

comment How do you make this colour displacement type image
-1: This answer uses a lot of fancy jargon, but actually says almost nothing beyond "it was done in Photoshop" (which might not even be true; there's plenty of other programs you could do this in, including vector graphics editors like Illustrator).

comment How do you make this colour displacement type image
Is your difficulty in making a triangular selection / mask, or in achieving the specific color shift effect in the first image?

comment How to create a crisp favicon
What exactly do you mean by "crisp"? Can you show an example of a "crisp" favicon? The icon you've posted looks about as crisp as it can be at 16x16 pixels. You could make it look sharper yet by getting rid of the anti-aliasing, but that would also make it look pixelated.

comment Why is it that this color gradient is so much more attractive than others?
Note that this is somewhat complicated by display gamma. To get an accurate luminescence value for a display RGB color, you should first apply gamma correction to convert the R/G/B values to a linear color space before averaging them using your formula. For a typical display gamma of 2.2, the correct formula is thus L = ( 0.2126 R^2.2 + 0.7152 G^2.2 + 0.0722 B^2.2 )^(1/2.2).

comment How can I represent speed in a graphic?
Wouldn't it generally be better to start with a shorter motion blur and just move the blurred layer so that the leading edge aligns with the original object? You can then use masking to fine-tune the effect if you want.

comment What factors do these colors share?
IMO, your rotated palette has a lot more apparent variation in saturation and luminosity than the original. I'd presume that's because the software you used to rotate it didn't use a gamma-corrected and/or visually uniform color space.
