Installing Ruby on Rails (ROR) in Ubuntu 11.10

Ruby on Rails (ROR) is a very popular framework for developing web applications that uses Ruby language. Here are the steps to install ROR in Ubuntu 11.10. I have referred the contents from the book, "Beginning Rails 3" by "Cloves Carneiro Jr., and Rida Al Barazi".

1. sudo apt-get update
2. sudo apt-get install build-essential libssl-dev libreadline5 libreadline5-dev zlib1g zlib1g-dev (Essential Libraries Required to Build Ruby)
3. Created a local directory and use wget to download Ruby. 
  mkdir `/src && cd `/src
4. wget
5. tar -zxvf ruby-1.9.1-p376.tar.gz (Extract the Downloaded Ruby Package)

6. Inside the Extracted Ruby Folder give the following command to Compile and Install Ruby.
./configure && make && sudo make install
7. ruby --version (to check the current ruby version)
Eg. ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]
8. Next, make sure the instance of Ruby that the shell is finding is the one you expect, which should
be in /usr/local/bin/ruby:
which ruby
Output : /usr/local/bin/ruby
9. Ruby uses a package-management system called RubyGems (
to manage the installation and maintenance of Ruby programs and libraries. Updating RubyGems is
Enter the following commands in a Terminal window, and you’re good to go:
sudo gem update --system
sudo gem sources -a
10. sudo gem install rails (Installing the Rails Framework)
11. Once installed check the version of Rails
rails --version
12. which rails  (to check which folder Rails has been installed)
13. Install SQLite database (
sudo apt-get install sqlite3 libsqlite3-dev
14. To check the version of SQLite
sqlite3 --version
eg. : 3.6.22
15. Installing the Ruby Library that Binds SQLite with Rails
sudo gem install sqlite3-ruby
16. Creating a test app to check whether Rails has been configured properly
rails new hello
17. cd hello/
18. bundle install (to build the project)
19. rails server
err :  Rails 3 doesn't officially support Ruby 1.9.1 since recent stable
    releases have segfaulted the test suite. Please upgrade to Ruby 1.9.2.
    You're running
      ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux]
10. Installing Ruby 1.9.3 
Replace line 4 with 
line 5 with tar -zxvf ruby-1.9.3-p0.tar.gz
20. In case it asks you to install libyaml and reinstall ruby, install libyaml using this command,
sudo apt-get install libyaml-libyaml-perl

  2. I have followed every steps you have posted here,
    and finally I set up ROR in ubuntu.

My 10 years in Application Development

It's been around 10 years since I started programming. May be a bit more, if I have to include my first attempts at C programming in school. But it would be a grave insult to call remembering ten lines of code and just replicating it to put a star on the screen. I also did a course on Visual basic, but it was more gimmicks that Application development. But it was truly in the year 2007 when I started my Master in Computer Applications that I found a new flare for developing applications. 
I was very late to computers in general and even when I joined my Masters, computers were not really accessible to me. But when I joined my Masters where one is actually expected to hone the skills which they already have, but in case it was were I was learning the skills, initially it was very difficult. I was not sure what computers had for me nor I had a natural flair for programming. But the thing about computers that attracted me was the visual medium it gave. Initially it was just a door t…

Changing Timezone in Postgresql, Ubuntu

Timezone and locale are integral concepts that one should be aware of when implementing a System. For example. if you create a database in PostgreSql, it will use the default System settings for the database. Lets say you have a server in UK and your client is US. If the client tries to retrieve the current date or time, it is going to show the UK time and not the US one.
Today I encountered a different issue in our client place where the Ubuntu timezone and PostgreSql timezone were showing a incorrect values. Instead of Indian Standard Time (IST) it was showing Pacific Daylight Time(PDT). These are the steps that I followed to change the timezone to IST in PostgreSql and Ubuntu.
Changing timezone in Ubuntu:
sudo dpkg-reconfigure tzdataYou will be prompted to choose the continent and then the area. Provided screen shots where we configure the location.
Use TAB key to navigate to the OK button and then press Enter.

The changes will get reflected immediately. To check it you can open a n…

Dissecting Openbravo 3.0 UI Architecture

Having been worked on Openbravo 3.0 UI for more than a year now (right from RC1) , Openbravo has leaped ahead of most contemporary ERP's in terms of UX design and usability. And a part of the credit has to go to the community too as they were actively involved in finalizing the UX and also involved enthusiastically in tested out the RC versions and providing their feedback.

In this post, I have tried to draw limelight on the basic UI components that are being used in Openbravo and their corresponding smartclient components. This is just to provide a very high level idea on how the entire architecture is coupled together. I have tried to use a single screen shot of Openbravo interface and tried to map the base components here.

The hierarchy can be visualized in simple terms as follows:

Exhaustive information on these components are provided in the Openbravo Wiki here.

Most of these components are defined and managed from individual files (or code) thereby making it really easy to …
