Here's the answer (I think) to how we will share logins across each of the modules in the Trauma/Burn project:

This line goes in config/environments/ production.rb or development.rb:


ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update
( :session_domain => '.example.com')

Note the . before example.com , that is what makes the sessions work
between subdomains.

(Thanks to Ezra Zygmuntowicz's post on the rubyonrails list.)

When we go into production, we'll put each module on a different sub-domain, and then this should work ... as long as we're naming all our session variables the same way. Of course, we need to choose a domain name first....

From Angela's EDU 223 paper in which she interviewed three people doing design projects, on what it means to design well:

Two of the three designers that I interviewed included creativity on their lists while only one said a good designer should understand the elements of what they are designing. They also included other attributes such as imagination, organization, and time management. As good as all of these are, only one of these individuals mentioned what I believe to be the most important attribute a designer should have, which is the ability to not be afraid of failing, which goes hand in hand with being confident in the project.

In the "what I did on my winter vacation" category, voila: Talking Walls. (Same goes for Gary, with apologies to our spouses.) It actually came out pretty well, though there's still plenty of things we want to add and refine. And on a tech note, we used just about every Rails feature we know, and even a few that we still don't quite understand.

Despite the fact that I'm very glad not to be working on it today, comments and suggestions are welcome.

The Monty Python folks apparently now work for the Association of International Glaucoma Societies. Don't take my word for it -- you have to visit the site to get the full effect. Don't miss the creepy blinking eye at the bottom of the menu. And the "Glaucoma Hymn" has to be heard to be believed.

I found this site through www.webpagesthatsuck.com, but "suck" really isn't the right word for this site. It's.... something else.

(And according to the webpagesthatsuck.com review, this is the improved version....)

This definitely looks worth a try...

Updates:

1. In the instructions above, I haven't gotten the rake to work, but it doesn't seem to matter.

2. See the thumbnail tutorial at: http://weblog.techno-weenie.net/articles/acts_as_attachment/thumbnailing

3. Change the create_or_update_thumbnail function as follows, in: vendor/plugins/acts_as_attachment/lib/technoweenie/acts_as_attachment.rb:

def create_or_update_thumbnail(file_name_suffix, *size)
returning thumbnail_class.find_or_create_by_thumbnail_and_parent_id(file_name_suffix.to_s, id) do |thumb|
thumb.attributes = {
:content_type => content_type,
:filename => thumbnail_name_for(file_name_suffix),
:attachment_data => resize_image_to(size)
}
callback_with_args :before_thumbnail_saved, thumb
thumb.save!
end
end

Here's the code from my demonstration implementation.

Update for IPD folks: If you're getting errors when you try to install, enter this command and then do the script/plugin commands:

export http_proxy="http://141.216.3.2:8080"

The reason has to do with an http proxy on the UM-Flint network....
