+---
+
+In this article I explain how to set up octopress with
+[pubsubhubbub](https://en.wikipedia.org/wiki/PubSubHubbub), to get
+push-enabled feeds. In my example I use [superfeedr](http://superfeedr.com/), which is free to use.
+
+After you signup up a hub, in my case [higgsboson.superfeedr.com](http://higgsboson.superfeedr.com),
+you have to add a hub reference to your atom feed.
+
+```yaml _config.yml
+# ....
+
+# pubsubhubbub
+hub_url: http://higgsboson.superfeedr.com/ # <--- replace this with your hub
+```
+
+Insert this line:
+
+{% raw %}
+``` xml
+    {% if site.hub_url %}<link href="{{ site.hub_url }}" rel="hub"/>{% endif %}
+```
+{% endraw %}
+
+into `source/atom.xml`. So it looks like this:
+
+{% raw %}
+```xml source/atom.xml
+<?xml version="1.0" encoding="utf-8"?>
+<feed xmlns="http://www.w3.org/2005/Atom">
+
+  <title><![CDATA[{{ site.title }}]]></title>
+  <link href="{{ site.url }}/atom.xml" rel="self"/>
+  <link href="{{ site.url }}/"/>
+  {% if site.hub_url %}<link href="{{ site.hub_url }}" rel="hub"/>{% endif %}
+  <updated>{{ site.time | date_to_xmlschema }}</updated>
+  <id>{{ site.url }}/</id>
+  <author>
+    <name><![CDATA[{{ site.author | strip_html }}]]></name>
+    {% if site.email %}<email><![CDATA[{{ site.email }}]]></email>{% endif %}
+  </author>
+  <generator uri="http://octopress.org/">Octopress</generator>
+
+  {% for post in site.posts limit: 20 %}
+  <entry>
+    <title type="html"><![CDATA[{{ post.title | cdata_escape }}]]></title>
+    <link href="{{ site.url }}{{ post.url }}"/>
+    <updated>{{ post.date | date_to_xmlschema }}</updated>
+    <id>{{ site.url }}{{ post.id }}</id>
+    <content type="html"><![CDATA[{{ post.content | expand_urls: site.url | cdata_escape }}]]></content>
+  </entry>
+  {% endfor %}
+</feed>
+```
+{% endraw %}
+
+To push out updates, you have to ping your hub, this is easily done in your
+deploy rake task.
+
+Add these lines to the end of your deploy task in your Rakefile:
+
+```ruby
+require 'net/http'
+require 'uri'
+hub_url = "higgsboson.superfeedr.com" # replace this with your hub
+atom_url = "blog.higgsboson/atom.xml"
+resp, data = Net::HTTP.post_form(URI.parse(hub_url),
+    {'hub.mode' => 'publish',
+    'hub.url' => atom_url})
+raise "!! Hub notification error: #{resp.code} #{resp.msg}, #{data}" unless resp.code == "204"
+puts "## Notified hub (" + hub_url + ") that feed #{atom_url} has been updated"
+```
+
+So you end up with something like this:
+
+``` ruby Rakefile
+desc "Default deploy task"
+task :deploy do
+  # Check if preview posts exist, which should not be published
+  if File.exists?(".preview-mode")
+    puts "## Found posts in preview mode, regenerating files ..."
+    File.delete(".preview-mode")
+    Rake::Task[:generate].execute
+  end
+
+  Rake::Task[:copydot].invoke(source_dir, public_dir)
+  Rake::Task["#{deploy_default}"].execute
+
+  require 'net/http'
+  require 'uri'
+  hub_url = "higgsboson.superfeedr.com"
+  atom_url = "blog.higgsboson/atom.xml"
+  resp, data = Net::HTTP.post_form(URI.parse(hub_url),
+                                   {'hub.mode' => 'publish',
+                                    'hub.url' => atom_url})
+  raise "!! Hub notification error: #{resp.code} #{resp.msg}, #{data}" unless resp.code == "204"
+  puts "## Notified hub (" + hub_url + ") that feed #{atom_url} has been updated"
+end
+```
+
+Now whenever you run `rake deploy`, it will automaticly update your hub.
