Add multiple virtual host along with Passenger
Posted on January 5, 2010, under Uncategorized.
I was having few projects on my MAC and was really bugged up with maintaining the port numbers and other stuffs, a real cumbersome.
After, Jacek’s thought on this, I had set up the following:
Install the gem:
sudo gem install ghost
after that add a virtual host
sudo ghost add paddy.local (a choice of your virtual host)
Install the Passenger gem:
sudo gem install passenger
sudo passenger-install-apache2-module
After installing the apache module for passenger, you may have add the following lines (after installation it will tell based on your own enviroment)
(in your httpd.conf)
LoadModule passenger_module /Library/Ruby/Gems/1.8/gems/passenger-2.2.8/ext/apache2/mod_passenger.so
PassengerRoot /Library/Ruby/Gems/1.8/gems/passenger-2.2.8
PassengerRuby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
Also you may have to enable your virtual host too …by default, it may be disabled(commented) and you have to enable(uncomment) it
# Virtual hosts
Include /Applications/XAMPP/etc/extra/httpd-vhosts.conf
Next, you have to add the vitual host for your rails app.
(httpd-vhosts.conf)
<VirtualHost *:80>
ServerName www.yourhost.com
DocumentRoot /somewhere/public # <– be sure to point to ‘public’!
<Directory /somewhere/public>
AllowOverride all # <– relax Apache security settings
Options -MultiViews # <– MultiViews must be turned off
</Directory>
</VirtualHost>
And you have to restart your apache server and start your respective rails app.
Happy Developing with Virtual Host
BSNL 3G Speed
Posted on November 23, 2009, under Uncategorized.
After a long awaiting for the actual launch of 3G service in Chennai, its available now. I rushed up to the customer service center and got myself the 3G Sim Card and just tried the net speed which BSNL claims upto 3.6 MBPS …but the result is shown in the below image

BSNL 3G Speed
The performance of BSNL 3G is not that bad on the data, but still i need to check it up.
Here’s the setting that I have used:
Access Point Name: GPRSSOUTH.CELLONE.IN
User Name your mobile number ( 94xxxxxxxx )
Password your mobile number ( 94xxxxxxxx )
Dailup No *99# OR *99***1#
The download seems to be atleast ok, but the upload speed is way too less.
This is it …for now from my desk …catch you up later
Cheers!

Git Stash
Currently, I am working on few files and when you do a git pull, you may sometimes get a message as follows:
error: Entry 'app/views/alerts/index.rhtml' not uptodate. Cannot merge.
So you know, somebody has updated the code and you do need to commit the file so that the file can be merged and for some reason I don’t want to commit till i finish the work. This is where git stash comes into play. from your root of the app, do the following command
1 2 3 | git stash
git pull
git stash apply #Apply your changes |

Run Controller Spec
If you just wanted to run only the controller specs, then you have to use the following command
1 | rake spec:controllers |
Restore the deleted files with GIT
Today, it was a shock, that I have deleted few files without my knowledge. Fortunately, before deleting I had committed the files and so no much of tension. You can use the following commands to restore it.
View the list of deleted files:
1 | git ls-files -d |
This will list the deleted file and lets restore it now.
1 | git ls-files -d | xargs git checkout -- |
Hope this helps somebody.
Cheers!
