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 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.

comment What's the most efficient way to “blank” old comic word balloons while retaining paper texture?
Also, if at all possible, do this before saving the images as JPEG. In the example images above, you can see that, even though the text itself is gone, some of the compression artifacts around it are still there. You'll get much better results with less trouble if you do this with the raw, uncompressed scans instead.

comment What's the most efficient way to “blank” old comic word balloons while retaining paper texture?
+1, this is what I would've suggested. One tip worth noting is that, if you want to do this to a lot of text at once, it can be useful to start by making a small separate layer filled with blank paper texture and then using it as a texture source. This speeds up the synthesis process (since there will be fewer rejections) and makes sure that it doesn't accidentally end up copying pieces of the surrounding drawing. Also, the full plugin (as opposed to the "heal selection" script) has a lot of setting you can play with to adjust the results.

comment How to make an image with transparent text on an opaque background?
I edited your question to make it clearer that you're not asking for us to design a logo for you, but simply how to achieve the transparency effect you want. At least, I assume that's what you're asking. (For the logo design, you're on your own; requests for free design work are off topic here.)
