In this post, we’ll show relationships between users based on mentions inside the tweet. After we collected the “who mentions who”, we then construct a directed graph to represent these relationships and convert them to an image so we can actually see it.
When is the best time to tweet? If you care about reaching a lot of users, the best time probably is when your followers are also tweeting. In this blog post, we will try to figure out the day and time users are the most active.
In this tutorial, I described the steps I did to deploy a simple Rails 3 application to Tomcat using JRuby. In addition, I show a way to make your Rails 3 application run side-by-side with a JRuby-based version.

I also included the problems I encountered along the way and how to solve them.
In this part, I shared the issues related to views and forms I encountered while upgrading to Rails 3.
In the second part of my Rails 3 upgrade series, I worked on Rails new routes. Eventhough rails:upgrade:routes handles most the cases, you may still need to manually fix your new routes to work with Rails 3 and in this post I showed the changes I did.
Part 1 of series of posts where I share my experience upgrading a Rails 2 application to Rails 3. In this post, I outlined the steps to upgrade and boot a Rails 3 app.
Using OpenAmplify with Ruby
I have just released a gem for the OpenAmplify API. If you are interested in text analysis, the OpenAmplify is a good place to start. I have written a short guide using the openamplify gem.
AMQP stands for Advanced Message Queuing Protocol. RabbitMQ is a server that implements the protocol. In this edition of Ruby on Cloud, I show a sample publisher and consumer code using AMQP.
I have written a short code to read google buzz updates using Nokogiri and Feedzirra. The Ruby code is here. Feedbacks are most welcome :)
