Interested in More About Nginx and WebSockets?

This blog doesn’t get a ton of traffic. At least not currently. But it’s pretty clear from the analytics that my post on proxying WebSockets with Nginx is by far the most popular thing I’ve written about to date. That article was fairly bare-bones, but people seem to find it useful, so I thought I’d just put the question out there: is there anything else related to the WebSockets functionality in Nginx you’d like to get some clarity on? Any examples you might find useful?

If so, please just let me know in the comments, and I’ll do my best to make some new posts covering the areas of interest.

What You Should Know About DNS

This post is from an earlier incarnation of this blog. I’ve gotten a few requests to republish it (the original post date was 2009-06-23), so here we go.

If, on the other hand, you fall into the overwhelming majority of people who need to “get it”, but don’t need every detail, hopefully this article will help you out.

Switching the Blog to MariaDB

WordPress, which is the blogging platform used to run this site, relies on PHP and MySQL to operate. A while back, Sun bought MySQL, and then Oracle subsequently bought Sun. Two of the most important pieces of that second acquisition were MySQL, and the Java programming language. Without getting into too much of the debates, many people feel that Oracle isn’t a great steward for either Java or MySQL. To that end, the original creator of MySQL forked the code and created an alternative called MariaDB. MariaDB aims to be a seamless drop in replacement for MySQL, with better performance and some extended features. I decided to see how “drop in” it really was by updating this site to use it.
