You certainly can!

Visit your repo page +"/compare" to setup the revisions you want to diff.
Or just construct the url:

https://github.com/gunn/ember.js/compare/emberjs:8446b121d8c635ebf...ember-libraries.diff

rm -rf /Applications/Safari.app
done.

You do know your audience.

I think that would be a kibigram.

Pffft.
And Liberia, and Myanmar.

Or another way to make it more fun - Godlike!

Hello.

Seeing as rails was not released publicly till July 2004 this is does not surprise me.

Seriously though, 5 years is a very long time for an open source project which has grown to have over a thousand people contribute code to it.

Perhaps with the release of rails 3, with its particular emphasis on modularity and configurability, it would be a good time to re-evaluate?

Also, I read you post and found no know-it-all reference.

Excellent documentation, good official tutorials:

http://guides.rubyonrails.org/

One of the goals of rails 3 is indeed a solid public api.
In fact because of rails' goal to be more modular / customisable the public api is going to constitute the only communication between rails' components.

ActiveRecord::Base.pluralize_table_names = false

simple.

Not true.

Model.find_by_sql sqlstring

or even more primitively:
ActiveRecord::Base.connection.execute( sqlstring )

Easy. Although you really shouldn't have to use it if you understand relations properly.

Also note that rails 3 is going to have Arel, an Object-Oriented interpretation of the Relational Algebra. It is a mathematical model for representing “queries” on data. It understanding relations this fundamentally means it can optimise easily.

Have a look at:

Well the command line would be one good way.
If you want a GUI gnome-schedule looks good too.

Looking at the PHP example here, I'm sure they'd be able to contrive such an example:
        PHP vs. revTalk

Just for interest though, here's a ruby version:

10 lines - 42% less code. And we could get that down to 6 if we were pushing it.
