Hacking a WRT54G v8 With DD-WRT

Posted by hank, Sat Oct 06 15:20:00 UTC 2007

So, last month sometime, BrainSlayer got DD-WRT working on version 8 of the WRT54G. Now this was great news to me when I read it since I’ve been wanting to get rid of the crappy LinkSys management from the beginning. Some of the procedure worked, and some of it didn’t for me.

Do not try this if you don’t know exactly what you’re getting into.

Fulltext Indexing Wikipedia with Sphinx

Posted by hank, Sat Sep 15 22:17:00 UTC 2007

So, earlier this year, I decided it would be cool to mirror Wikipedia. So, I successfully set up a local copy on my system, and it’s been just sitting there ever since. But lately, I’ve been interested in fulltext indexing offered by various indexing engines, and Sphinx has looked especially tasty. So, I figured I’d sit down and try it today.

How to make a Mephisto Plugin

Posted by hank, Mon Feb 26 00:29:00 UTC 2007

So, I figured I might as well provide a quick tutorial on how to make Mephisto Plugins currently. Many of the old plugins are broken, so there needs to be a resurgence of plugin development. Here’s the basic structure of the Tag Cloud plugin:


mephisto_tag_cloud
 - init.rb README
 - lib
   - mephisto_plugins
     - tag_cloud.rb

As you can see, the structure is very simple. Here’s my code for init.rb

Liquid::Template.register_filter(MephistoPlugins::TagCloud)

That’s it! No require or anything! Next, I edited lib/mephisto_plugins/tag_cloud.rb:

module MephistoPlugins
  module TagCloud
    def size_tag(tag, largest = 2)
      size = (Tag.find_by_name(tag).taggings(true).length + 18).to_f / 18
      size = largest if size > largest
      "<span style='font-size: #{size}em'><a href='/tags/#{tag}'>#{tag}</a></span>"
    end
  end
end
