Rails 2.3 introduces a hot new feature: Rails Metal. Metal allows you to build Rack endpoints for selected URLs in your app. Optimize your high-frequency, low-complexity actions with Rails Metal and get a 2x – 3x performance boost.

Even better: you can use Sinatra, the microframework that everyone’s talking about, from Rails Metal. Capture the speed and elegance of Sinatra from within your existing Rails app!

This talk will provide a brief overview of the basics of Rack and Sinatra, so no prior knowledge of either project is required.

I was hoping for more from this. It was pretty much a primer of everything I already knew about rails metal and rack.

more details on Rack and how it works would have been good. Overall, good talk.

I could have got this by reading one blog post or a Readme.

Good follow up to yesterday’s Sinatra presentation. Probably would not have made experienced people happy as Adam started at a lower level with a good introduction. But that is a problem through out the conference so far. Either the people new to Rails are unhappy or the advanced are. It is impossible to provide information to satisfy both levels in a short presentation.

Gave me additional confidence to use SInatra/Metal in my application particularly in the API area.

Too brief and too much of an overview. I can overlook the minor syntactic problems on the slides, but it would have been nice to see a full Rack+(Sinatra/Metal/Rails) instead of just the parts in isolation. More detail on Rack would have been a great step toward a better rating.

Good intro to Sinatra use in Rails. Would be nice to have more technical details – hard to do in 50 mins. Great presentation.
