Interesting discussion about object decoration in ruby.

nice post about class and instance vars in ruby.

• class and instance methods
• include vs extend again

tables:

SELECT 'DROP TABLE ' || table_name || ' CASCADE CONSTRAINTS;' FROM user_tables;

sequences:

SELECT 'DROP SEQUENCE ' || sequence_name || ';' FROM user_sequences;

Looks like google engine will support java. Pretty exciting

Here are few links which helped me understand few ruby concepts:

• include vs extend
• include,extend,module_eval,class_eval
• anonymous classes (aka singleton classes)
• ruby-metaprogramming-techniques

GIT is becoming more popular so I’ve decided to start using it. I found few good resources:

• http://www-cs-students.stanford.edu/~blynn/gitmagic/index.html
• http://gitcasts.com/
• https://37s.backpackit.com/pub/1465067
• http://www.kernel.org/pub/software/scm/git/docs/everyday.html#Integrator
• http://hoth.entp.com/output/git_for_designers.html

A Friend of mine introduced me to GNU screen a great tool which can be used in different ways. One of them is a session sharing which is awesome when 2 or more people are working together in Linux env.

I’m still looking around for a stage deployment setup with Capistrano.
Here are few ideas/links I found useful.

• multi_staging_environment_for_rails_using_capistrano_and_mod_rails
• deploying-to-staging-and-production-with-capistrano
• using-capistrano-with-passenger-mod_rails/

Update:
It turned out this is pretty simple with the capistrano-ext gem:
http://weblog.jamisbuck.org/2007/7/23/capistrano-multistage

set :default_stage, "development"
set :stages, %w(production testing development)
require 'capistrano/ext/multistage'
