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'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:

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.

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.

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.

comment www.*.us.com not being indexed, but *.us.com is on Google Webmasters
@Ojal: That's because it is a subdomain of us.com, which is owned by the company that sells the subdomains, CentralNic Ltd. It's not a top-level domain, although it looks confusingly like one. The actual ccTLD for the United States is just .us.

comment How do I transition to SSL without affecting PageRank?
@Nick: Would it really be 95%+? I can see that fraction of all your requests coming from Google, but surely the percentage must be a lot lower for logged-in users? That said, I do agree that a full second of extra latency does start to qualify as "painful". (You could solve that issue, and improve your latency in general, by having a bunch of geographically scattered front-end proxies, but that might be going a bit outside the scope of the question here... still, it works for Wikipedia.)

comment How do I transition to SSL without affecting PageRank?
@Nick: Would the delay from redirecting logged-in users from HTTP to HTTPS with a 302 really be that "painful"? It's just one request: with a reasonably efficient implementation, we'd be talking about a few hundred milliseconds at most, even from here across the ocean. Not that I think there's anything wrong with your current plan, just asking.

comment Forwarding non-www domain to other domain using DNS
What's wrong with it is that, as far as browsers and search engines are concerned, those would be two completely different domains with (assuming no funny webserver tricks) the same content. Of course, you can first use a DNS CNAME to make your old domain an alias for your new one, and then configure the webserver at your new domain to HTTP 301 redirect any requests for URLs on your old domain to the new one.

comment Google indexed URLs both w/ or w/o trailing slash
+1 for mentioning 301 redirects, which really are the correct tool to use in this case. Using rel=canonical links will work too, but they're less efficient and less widely supported, and should generally only be used in cases where 301 redirects are not practical.

comment Multiple IP addresses to a server
That's a good point. Depending on circumstances, you might be able to use wildcard and/or SAN certificates, which are supported even by IE on XP, instead. They do have some limitations compared to SNI, but those aren't too serious unless you're planning on running a shared webhosting service or something. (Wildcard certs only apply to subdomains of a single domain name, and SAN certs need to be reissued every time new domain names are added to the server.)
