//OP:rvm 1.8.4 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]
 

6. Install ruby 1.8.7 or 1.9.2 (according to your need)
rvm install 1.8.7

7. Set default ruby 1.8.7 
rvm --default use 1.8.7

rvm gemset create rails3

Manage git repos on S3

Use jgit to manage git repos on Amazon S3

Download jgit.sh from here and put jgit in your $HOME path

Make a .jgit file in your home directory and put

accesskey: *******************
secretkey: ********************



Make a bucket for git repos say git-repos

Now got to your project directory and add a remote for Amazon S3

>cd git_project

>git remote add s3 amazon-s3://.jgit@git-repos/git_project.git



>git push s3 branch

and it's done.

Couldn't forward the HTTP response back to the HTTP client: It seems the user clicked on the 'Stop' button in his browser

One day in the morning I got the following error in one of my rails application with passenger on my development machine but other applications are working fine on the same passenger server.

Couldn't forward the HTTP response back to the HTTP client: It seems the user clicked on the 'Stop' button in his browser

After two days i got to know that it is due to mistakenly setting

Rails.env = "production"

for my development mode in Rails.root/config/application.rb
