I submitted the patch to active merchant plugin for Canada payment gateway BeanStream. I guess that it will take some time to get reviewed, tested and accepted ( or not accepted because the remote test can not be passed without beanstream's test account which it doesn't provide it to me), so I uploaded the patch to a google code project:
http://code.google.com/p/activemerchant-patch-for-beanstream/
The installation, description and a simple example have been already written in the project home page. Issue your bug or give me your feedback if you encounter any problem when using it.

Rails send emails with actionmailer and gmail
The first step is to configure your rails application to work with gmail, I just copied the 2 simple steps from the Preston Lee's article:
1. Save this code as lib/smtp_tls.rb within your rails app;
2. Add this code to config/environment.rb
The second step is to learn to use actionmailer, just follow the document "How to send emails with action mailer" to do it then you will understand how it works pretty fast.
1. ruby script/generate mailer Notifier signup order_created
2. add code to your app/models/notifier.rb, such as
3. add code to /app/views/notifier/signup.erb
4. use the mailer in where you want.

Rails Mongrel and Apache servers work with SSL, certificates and https
I am already running Apache as the front end server and Mongrel Rails Cluster Servers as the back end. To make them work with SSL, certificates and HTTPS, there are several easy steps to finish.
# 1. make a directory to store ssl key and certificates
# 2. create openssl key and make it secure
# 3. create CSR file (certificates signing request)
# Common name is your domain name without http:// but with www.
# 4. I bought godaddy's ssl certificate
# And got the certificate by email in 5 mins after I submitted the CSR.
# 5. Config apache's yourdomain config part
# Assuming that you have configurated yourdomain.common and yourdomain.cluster_proxy.conf properly.
# 6. install and use plugin ssl_requirement
# 1. make a directory to store ssl key and certificates
mkdir /etc/httpd/conf/ssl
# 2. create openssl key and make it secure
cd /etc/httpd/conf/ssl
openssl genrsa -des3 -out yourdomain.key 1024
chmod 600 yourdomain.key
# 3. create CSR file (certificates signing request)
# Common name is your domain name without http:// but with www.
openssl req -new -key yourdomain.key -out yourdomain.csr
# 4. I bought godaddy's ssl certificate
# And got the certificate by email in 5 mins after I submitted the CSR.
Download the CSR zip file, unzip the two certs into ssl directory
# 5. Config apache's yourdomain config part
# Assuming that you have configurated yourdomain.common and yourdomain.cluster_proxy.conf properly.
virtualhost
ServerName www.yourdomain.com:443
Include /etc/httpd/conf/yourdomain.common
RequestHeader set X_FORWARDED_PROTO 'https'
ErrorLog logs/yourdomain_ssl_errors_log
CustomLog logs/yourdomain_ssl_log combined
SSLEngine on
SSLCertificateFile /etc/httpd/conf/ssl/yourdomain.crt
SSLCertificateKeyFile /etc/httpd/conf/ssl/yourdomain.key
SSLCertificateChainFile /etc/httpd/conf/ssl/gd_intermediate_bundle.crt
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
/virtualhost
# 6. install and use plugin ssl_requirement
script/plugin install ssl_requirement
include SslRequirement (in your application.rb)
ssl_required :login, :orders (in your controller with those actions)
