Rack Cache on Cedar Rails 3.1+ Applications

Though slightly more complex, using a CDN is the most performant option for serving static assets. See the [CDN asset host](cdn-asset-host-rails31) article for more details.

Ruby on Rails applications should use Rack::Cache to efficiently serve assets on the Cedar stack. Proper Rack::Cache usage improves response time, decreases load and is important when serving static assets through your application.

This article will summarize the concepts of caching assets using Rack::Cache and walk you through the appropriate configuration of a Rails 3.1 application and the asset pipeline.

Sample code for this article's [reference application](https://github.com/heroku/rack-cache-demo) is available on

[HOWTO] Ubuntu 12.04 Ruby on Rails Development Environment

Ubuntu 12.04 Ruby on Rails Development Environment

I haven't set up an install guide for the latest ubuntu release, largely because the last set of instructions worked pretty closely with the latest and greatest Ubuntu, 12.04 Precise Pangolin, however when installing today, I found that there were enough differences in the way that I configure my setup to justify an update, so here it goes. Yes, I'm late to the party, but a quick google search didn't find anything that I felt was as complete for my requirements as my previous install guides, so here I go.

As always with my install guides, I have included here is just about everything you'll need (and then some) to get started with ruby on rails development with Ubuntu 12.04 as a platform. These are my settings and preferences, and this is certainly not the only way of doing things, so keep that in mind.

Step 1: Get the repos ready and run updates.

sudo apt-get update && sudo apt-get upgrade

##git mergetool

In the middle file (future merged file), you can navigate between conflicts with ]c and [c.

Choose which version you want to keep with :diffget //2 or :diffget //3 (the //2 and //3 are unique identifiers for the target/master copy and the merge/branch copy file names).

:diffupdate (to remove leftover spacing issues)

:only (once you’re done reviewing all conflicts, this shows only the middle/merged file)

How to use rails load paths, app, and lib directories.

In Rails 3

NOTE: This post now lives (and kept up to date) on my blog: http://hakunin.com/rails3-load-paths

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.
