Introduction to nginx.conf scripting. Slideshow—hit left arrow to navigate through the slides. The nginx community is officially nuts. Starts out with a simple “Hello world” using the echo module, then rapidly descends down the rabbit hole in to array operations, sub-requests, memcached connection pooling and eventually non-blocking Drizzle SQL execution against a sharded cluster—all implemented in the nginx.conf configuration file. # 21st April 2010, 11:40 pm

How We Made GitHub Fast. Detailed overview of the new GitHub architecture. It’s a lot more complicated than I would have expected—lots of moving parts are involved in ensuring they can scale horizontally when they need to. Interesting components include nginx, Unicorn, Rails, DRBD, HAProxy, Redis, Erlang, memcached, SSH, git and a bunch of interesting new open source projects produced by the GitHub team such as BERT/Ernie and ProxyMachine. # 21st October 2009, 9:14 pm

Ravelry. Tim Bray interviews Casey Forbes, the single engineer behind Ravelry, the knitting community that serves 10 million Rails requests a day using just seven physical servers, MySQL, Sphinx, memcached, nginx, haproxy, passenger and Tokyo Cabinet. # 3rd September 2009, 6:50 pm

Nginx and Memcached, a 400% boost! Ilya Grigorik wrote up my current favourite nginx trick—you set nginx to check memcached for a cache entry matching the current URL on every hit, then invalidate your cache by pushing a new cache record straight in to memcached from your application server. # 11th February 2008, 10:05 pm

NginxMemcachedModule. nginx can be set up to directly serve a URL from memcache if the corresponding cache key is set, and fall back to a backend application server otherwise. Application servers can then write directly to memcache when content needs to be cached or goes stale. # 15th December 2007, 1:59 am
