Hi there quiet recently I had a big problem with this guy - gem install pg

It threw me :

$ gem install pg
Building native extensions.  This could take a while...
ERROR:  Error installing pg:
	ERROR: Failed to build gem native extension.

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 issued - Go to your certificate authority and give them the CSR (server.csr)

4. Copy your new crt (that the certificate authority issued) 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.

My issues with Modules

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.

class Article < ActiveRecord::Base

rkjha

upstream myapp_puma {
  server unix:/tmp/myapp_puma.sock fail_timeout=0;
}

# for redirecting to https version of the site
server {
       listen 80;
       rewrite ^(.*) https://$host$1 permanent;
 }

    # Page size of the database. The page size must be a power of two between 512 and 65536 inclusive
    c.execute 'PRAGMA main.page_size=4096;'

    # Suggested maximum number of database disk pages that SQLite will hold in memory at once per open database file
