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 do two perfectly adjacent rectangles create black or white lines in between as if they were overlapping or not exactly adjacent?
@Lilienthal: I've never seen it; then again, the whole point is that you're not supposed to see it. I suppose one reason why the need rarely arises in practice is that most designers tend to avoid putting such strongly contrasting pure colors next to each other anyway.

comment Add transparency to an existing PNG
@Boris_yo: It's hard to tell why that might be, without seeing the actual pictures, but the techniques from this answer might help. Of course, you'd have to adapt them to Paint.NET yourself.

comment Add transparency to an existing PNG
@Boris_yo: Looks like the Unblend plugin for Paint.NET should do the same as Color to Alpha in GIMP. I haven't tried it myself, though.

comment How would you represent distance graphically?
It might help if you added some context -- specifically, what is the distance you're trying to represent, and for what purpose?

comment How to use font variants within Inkscape
Related, maybe even a dupe: graphicdesign.stackexchange.com/questions/16873/… (but I think this one is better asked).

comment .png's made in GIMP not coming out transparent
I... rather doubt that's the issue. The OP says they "remove the background" after adding the alpha channel, and however they're doing it, it does sound like they know how to do that. That said, there's not enough information in th question to really diagnose the issue, so I can't completely rule out the possibility that you might be right after all.

comment .png's made in GIMP not coming out transparent
It might help if you could post some "before / after" images demonstrating the effect (and, if possible, a third image demonstrating the outcome you actually want). If the image looks OK in GIMP before you export it, a screenshot might also help.

comment Changing the background of the picture to white
@Servant: I think that one's beyond my skills. If possible, I'd suggest just taking another photo.

comment How do you explain the value of native files to an uneducated client?
While you're sort of right about the source code thing (that is, assuming you ignore the huge amount of open source software out there -- but that's fair enough, since it's rarely custom-written to spec), it should also be noted that software development contracts usually do include either delivery of source code or some kind of continued support provision. Otherwise, who's going to fix bugs in your fancy new software, or update it when it stops working with the latest version of some other program?

comment How do you explain the value of native files to an uneducated client?
I have to give you a +1 because, although I (deliberately) wrote my own answer from almost a diametrically opposed viewpoint, I agree 100% with your core message: there's no point in trying to "explain the value of native files" to the client, since they have no reason to care what you think they're worth. In the end, it just comes down to whether you and they can haggle a price that you're willing to accept and they're willing to pay.

comment How do you explain the value of native files to an uneducated client?
I can't really comment on your other examples, but I'd just like to note that, IME, almost all non-commodity software comes with either source code or a support contract, or possibly both. (For that matter, thanks to the free software / open source movement, a lot of commodity software comes with source code too nowadays, but that's only tangentially relevant.)

comment Invisible Barcode
I'm going to go out on a limb and say "no." Would be cool if it were, though.

comment Why does this PNG image on twitter look different when clicked?
See also this answer to another question, where I describe how pictures like this work and how to create them.

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.
