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 How did Google find my unlinked newly created pages?
That's odd, then. Still, it only takes one link. You might want to look at the links to your wiki pages on GWT and see if you can spot any from outside the wiki.

comment How did Google find my unlinked newly created pages?
Actually, AFAIK, MediaWiki normally doesn't do that. But if you added the new pages to an existing wiki that Google knew about, then it could've reached them via any number of pages (e.g. Special:Recentchanges, Special:Allpages, Special:Random...).

Are you using a CMS / wiki / blog / etc. platform of some kind? Some of those ping Google whenever you add new pages.

comment Adding direct advertisements to a mediawiki installation
I'm not sure why this was closed as "asking for recommendations", given that you explicitly say that you want to implement the ads yourself. Still, you question is kind of vague, but the general solution to "How do I add things to the sidebar?" is to use a SkinBuildSidebar hook.

comment One million redirects
+1. Of course, if you can write a program to generate the new URLs from the old ones, then you won't even need to store them in a database. (Also, if you do use a database, creating an index on the old URL column is highly recommended...)

Related, possibly duplicate: Why do Google search results include pages disallowed in robots.txt? (Disclosure: Asked and answered by me.)

comment .htaccess file to implement multiple redirects
No, not without more information from you, I can't. Answer me this: Imagine that I'm your webserver. Given the URL domain.com/my-new-page, how am I supposed to tell that it should be rewritten to manual-page.php rather than to flights.php? If you can tell me that, maybe I can tell you how to program your actual webserver to do it.

comment .htaccess file to implement multiple redirects
@RobMorta: As I said, first you need to decide how you're going to tell the two kinds of clean URLs apart. Come back once you've figured that out.

comment Getting a lot of '/_' errors from webmaster tools
That's strange. This similar question and this answer to another related question suggest that these URLs might once have been linked from somewhere, and perhaps might have actually worked, and Google now keeps trying to recrawl them because it thinks there used to be something there. Sending a "410 Gone" response or redirecting them to a working URL might help, as might using the URL removal tool on Webmaster Tools.

comment Getting a lot of '/_' errors from webmaster tools
Have you checked where those pages are being linked from? (Click on the page name on the list under "Health > Crawl errors", then open the "Linked from" tab on the popup.)

comment I want to combine the databases from two different sites under one URL. How is this possible?
OK, fair enough. If you edit that into your question, I can take back my downvote. Do note that there's also a specific Stack Exchange site for Wordpress; you might try re-asking your question over there if you don't get any good answers here.

comment I want to combine the databases from two different sites under one URL. How is this possible?
The answer depends entirely on the software you're using to run the sites, which you haven't specified. If you wrote your own code from scratch, the answer would be "OK, so just do it." (and you wouldn't be asking this question in the first place). If you're using code written by someone else, the answer then depends on whether that code supports such a feature out of the box, or whether you know enough to modify it to do that.
