Animated. Interactive. Click & Drag. Middle mouse to zoom. Press 1 through 9 for animations. The above is a data pipeline animation for one of my recent...
It has been a while since I added contents to the website. I started out this blog in 2004, back when blogging was the social media of the day. Inspired by professionals who I admired, I tried to track my own professional and personal journey. However, in 2016 I failed to renew my hosting plan which took down all...

And Second; NUI styled-elements are not masked/wrapped in their special...
I’ve recently upgraded a JRuby/Rails application from JRuby 1.6.3 (1.8 compatibility mode) to 1.6.8 (1.9 mode). Everything was working out fine except for actions relying on internal CSV library (FasterCSV in 1.8 mode). The error “ was thrown as CSV tries to generate the csv string. This had the hallmarks that the application was still under the 1.8 mode...
Consider that we have two models; Well and SurveryPoints . A Well represent an oil/gas/water well, each with multiple SurveyPoints. A SurveyPoint represent the well’s coordinate at a certain depth. class Well < ActiveRecord::Base has_many :survey_pointsendclass SurveyPoint < ActiveRecord::Base belongs_to :wellend Say, we’d like to implement a filtration mechanism that allows us to query the wells – and for...

To resolve (following suggestions on the trinidad google group): {% highlight ruby %} config/initializers/newrelic.rb if defined?(JRUBY_VERSION) &&...
Rails streaming is a great feature that allows you to optimize on server resources when dealing with large generated content. However – it might be a bit tricky to validate and test in local development. First off – a local server that supports streaming is required. The only one I could find was trinidad which is moving to the...
