It's now been updated to version 0.8.6 -- but 'gem install' and 'gem update' will find the latest version only if you use the new name.

The only issues I had with the deploy.rb files were (note, I am not sure if this was specifically to do with my using GIThub or not): I also had to add these two lines here (deploy.rb), then it worked. ssh_options[:port] = 22 ssh_options[:forward_agent] = true This worked out very wellfor me.

A couple weeks after I turned in my project, I imported the entire real Harvard Extension School catalog into my data model. I then had to add .force_encoding('utf-8") calls to a bunch more places in my views to avoid the Encoding::CompatibilityError when I navigated to various pages. (The catalog has several course titles, course descriptions, and instructor names that contain accented non-ASCII characters.)

It is intended to contain the complete Harvard Extension School catalog, but right now it only has some sample data: a small number of courses from the ARAB, CSCI, and SPAN departments. The idea is that a user can read comments left by other users about classes they have taken, and logged-in users can add new comments. There isn't currently any user authentication (I just borrowed the user and session code from Assignments 4 and 5). Please play with it, try to break it, and ask me any questions about it. My e-mail address is: rnewman@thecia.net . The app includes a read-only RESTful service, but I'm not sure how to release my client to the public. The next thing I'm going to try to do is to write a screen-scraping script that reads the official Harvard Extension School website's course list and adds all of that data to my database.

I used the VMWare player but only because I've used VMWare before.

You're right about having to teach Unix too.
