Golang Workers / Job Queue

A running example of the code from:

This gist creates a working example from blog post, and a alternate example using simple worker pool.

Generate sitemap.xml in Rails app

This post shows how to make sitemap.xml for your web site. The sitemap will be accessible by URL http://mysite.com/sitemap.xml

Routes

Myrails::Application.routes.draw do

To enable the precompilation of all non.js/.css assets within vendor/assets just add this to config/initializers/assets.rb:

Rails.application.config.assets.precompile << Proc.new { |path, fn| fn =~ /vendor\/assets/ && !%w(.js .css).include?(File.extname(path)) }

Be aware that this will precompile ALL non .js/.css assets that you have there, some plugins or libraries might have .txt or other files around, and those would end up into your precompiled list also.

If you need to precompile images only, you could use this:

Rails.application.config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif)

This workaround install is necessary because PDFtk was pulled from homebrew-cask due to issues with it aggressively overwriting file permissions that could impact other installed libraries. See this homebrew-cask issue.
