The celluloid gem looks really interesting. It may not be the most Rails-centric item, but it's still something that looks really cool for anyone wanting to do concurrency in their app.

I know it's just fantastic to deploy a rails app to heroku, but AWS seems have no restriction on domain queries and resolves queries faster.
What baffling me when I try to deploy a rails app to AWS free tier is that the SSH keys set up and gems setup are confusing.
So I am just wondering if you could do an episode on that.

I want to learn how to put up a maintenance window with my Rails Application. Serve a static html page while bringing down the rails application server.

I just recently discovered the DCI pattern. It was apparently part of RubyConf2011: http://en.oreilly.com/rails2011/public/schedule/detail/19424

At work, we talked about this pattern, but it's hard to grok and harder to see specific examples where it is beneficial, rather than just another layer of abstraction.

It's a gem for Google maps and Rails 3. Available on github: https://github.com/apneadiving/Google-Maps-for-Rails

Instead of doing it from scratch, you can now use https://github.com/ronalchn/ajax_pagination.

It makes it much easier to do pagination, with updates via javascript, without having to code all the bells and whistles manually (such as a loading image etc).

It'd be great to show http://torquebox.org/

Picky is a really easy to use and fast Ruby search engine that helps your users find what they are looking for.
http://florianhanke.com/picky/

show tipical use example.

Topics would include geo-searching, facets delta indexing, and other advanced search features.

Given new technology like Siri[1] as well as the requirements of less enabled web users, it would be really nice to have at least an episode talking about accessible web design and best practices.

With the proliferation of NoSQL and NewSQL dbms, it seems that rails apps may be able to take advantage of a "right tool for the job" mentality when setting up database systems. A railscast that covers relevant ORMs/ODMs, and how to hook in multiple DBs to an app would be nice :).

Rather than using a services like Payloadz etc. I would love to know how I could easily generate time degrading urls for secure assets on Amazon S3.

This would be part of a system to sell videos and other files.

Thanks

This RoR CMS seems to be userfrendly but needs more explanations to understand how to setup... I found this http://www.tommyblue.it/2011/02/28/how-to-build-a-website-with-locomotive-cms-from-scratch/ whitch could be a base of the Episode...

This is the real deal. Up and running from the command line into one or more cloud instances, with scalability. Add this to a complete application demo and you have a 100% turn key solution. While AWS might not be right for everyone, it's a good way to get applications on line for demo purposes to clients and investors, while at the same time being a plausible final deployment.

The rubber plugin enables relatively complex multi-instance deployments of RubyOnRails applications to Amazon’s Elastic Compute Cloud (EC2).

Uploading files using CarrierWave, HTML 5 drag and drop feature, AJAX (upload progress bar), and attachment processing in background (delayedJob, Resque, ...)

I think this topic is not covered with the attention it deserves. Views are very important part of the app and onle tested in conjunction with controllers (in functional tests or integration/acceptance one).

There is http://rspec.info/rails/writing/views.html but it has too little info.

Thanx!
