Victor S's questions

If kernel type (64/32) is no indication of what bit your distribution is, how do I know what I'm running? I'm on Ubuntu, and I just found out, to my surprise, you can use a 64 bit kernel on a 32 bit Linux distribution... so how can I tell for sure what type of software I'm running, 64 bit or 32 bit?

I'm in a strange situation, I install bundler in my RVM gemset, it sais it installed correctly, but when I try to run it asks me to to install bundler again: here is a transcript of my terminal interaction:

abc@li243-166:/srv/www/dinner/current$ bundle
ERROR: Gem bundler is not installed, run `gem install bundler` first.
abc@li243-166:/srv/www/dinner/current$ gem install bundler
Successfully installed bundler-1.3.5
1 gem installed
abc@li243-166:/srv/www/dinner/current$ bundle
ERROR: Gem bundler is not installed, run `gem install bundler` first.
abc@li243-166:/srv/www/dinner/current$

I'm trying to run the meteor documentation server and my app at the same time, but I can only run one at a time, out of the box. They both run their own instance of mongodb and so the ports colide...

I have a web application that needs to support custom domains, in that regard I have set-up the following name based virtual server:

<VirtualHost *:80>
    ServerName example.com
    ServerAlias * *.example.com www.example.com example.com
    RailsEnv production
    RackEnv production
    DocumentRoot /srv/www/example/current/public
    <Directory /srv/www/example/current/public>
             AllowOverride all
             Options -MultiViews FollowSymLinks
    </Directory>
    ErrorLog /srv/www/example/log/error.log
    TransferLog /srv/www/example/log/access.log
</VirtualHost>

Notice the * as the server alias? that catches all the domains on that server. However, I have other sites on this server which I want to be excluded from this list. It is more economical for me to have a list of excluded domains than manually set every domain a user may register with at this service as a serverAlias...

Perhaps this is not the best way to go, but I'm looking for help, in the best (relatively simple) way to set up a web-app that may catch any domains, while allowing other specific domains to be routed to different apps.
