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 Can anyone help me identify the font for these house numbers?
The "9" looks a lot like Helvetica, or one of the many similar sans-serif fonts, but the "8" is pretty funky. Off the top of my head, I can't think of any font with an "8" like that, and neither can any of the search tools I tried.

comment When should someone use ligatures?
You should've just told them that "it's deliberate, to make it look better." No need to go into details about ligatures -- just let them assume that you customized the text yourself.

comment Find the font from a single character
@Tracy: WhatTheFont is a great tool, but I do wish people recommending it on a specific font-identification question with a clear sample image would at least try it first. It shouldn't take too many seconds to paste the image URL from above into WhatTheFont and to observe that, no, in this case none of the returned matches are anywhere close to correct.

comment Trying to identify a font or typeface with a letter “A” shaped like a triangle
@travelsonic: Based on this photo, I'd say it's similar, but not quite the same; the 7 looks very close, but the 5 has some obvious differences, like the hook at the bottom end and the fact that the white centerline doesn't seem to stay at the center.

comment How to comply with sharealike clause when using creative commons cc-by-sa licensed images in commercial work?
@THoldaway: Unlike, say, the GPL, the CC licenses don't contain any requirement to distribute the "source code" of derivative works. So you don't really need to distribute anything but the T-shirt itself. You do need to comply with the attribution and licensing requirements; depending on how one interprets the license, you might need to print this information on the shirt itself, or maybe on a label sold with the shirt.

Also, FWIW, the new logo appears to be based on a Helvetica-like font; WhatTheFont suggests Nimbus Sans P Black Italic as the closest match.

+1, well spotted. Specifically, the Univers Extended ExtraBlack Oblique cuts are a pretty good match.

comment How to create an EAN-13 barcode with a font?
Clever, but still a lot of hard work compared to, say, using the barcode generator in Inkscape. No matter how well written it is, I'm afraid I'll have to give this answer a -1.

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.

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.)
