1. Open a command prompt and navigate to /etc/nginx/ssl | |
2. issue "openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr" | |
3. Get your certificate - Go to your certificate authority and give them the CSR | |
4. copy your new crt to the /etc/nginx/ssl and give it read priveledges | |
5. reconfigure your nginx.conf, here is mine. The first part redirects 80 to 443, the second part listens to 443 and is optimized to return Ruby on Rails application requests using gzip and unicorn. |

In researching topics for RailsCasts I often read code in Rails and other gems. This is a great exercise to do. Not only will you pick up some coding tips, but it can help you better understand what makes code readable.
A common practice to organize code in gems is to divide it into modules. When this is done extensively I find it becomes very difficult to read. Before I explain further, a quick detour on instance_eval
.
You can find instance_eval
used in many DSLs: from routes to state machines. Here's an example from Thinking Sphinx.

This script installs a patched version of ruby 1.9.3-p194 with boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.
Many thanks to funny-falcon for the performance patches.
