At the first Rails Edge conference, Jim
, Bruce Williams, and I were chatting about how to improve the
RubyGems platform-specific behavior, when we realized that it would be
really helpful to have more info about the install footprint of the
Ruby community at large.

So instead of going right into hacking RubyGems as was our plan, we
created a little census tool and an accompanying web site to help us
collect information. Most of the info we collect is from
Config::CONFIG, with the addition of the RubyGems version.

We know this information will help the implementers of RubyGems, and
we hope it will also help Ruby implementers and library developers as

To install:

$ sudo gem install tattle

To submit your info:

$ tattle

If you want to see what would be posted before posting, you can do:

$ tattle report

The information gets posted to You can
view the posted data with your web browser at that URL.

As a side note, Eric posted the latest RubyGems beta this weekend. Please do give it a go if you’re so inclined.
