Points on how modules can make code difficult to read.

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.

Dynamic (AJAX) loaded Bootstrap Modal (Bootstrap 2.1)
$(document).ready(function() {
// Support for AJAX loaded modal window.
// Focuses on first input textbox after it loads the window.
$('[data-toggle="modal"]').click(function(e) {
e.preventDefault();
var url = $(this).attr('href');
if (url.indexOf('#') == 0) {
$(url).modal('open');
} else {

Upgrading PostgreSQL from 9.3 to 9.5 on Ubuntu

TL;DR

Install Postgres 9.5, and then:

sudo pg_dropcluster 9.5 main --stop
sudo pg_upgradecluster 9.3 main

Live stream a database dump (or any other STDOUT) using Rails 4. Why would you want this? If you have a large database dump and want to avoid storing it in memory as Rails streams it. This allows pipe the dump directly into the http response instead of storing it as a file, sending it, and then deleting it. Let me know what you think! I've teste…
class DatabaseController < ApplicationController
def database_dump
database = Rails.configuration.database_configuration[Rails.env]["database"]
send_file_headers!(:type => 'application/octet-stream', :filename => "#{database}_#{Time.now.to_s(:human)}.backup")
pipe = IO.popen("pg_dump '#{database}' -F c")
stream = response.stream
while (line = pipe.gets)
stream.write line
sleep 0.0001 # HACK: Prevent server instance from sleeping forever if client disconnects during download
