Re: free vs. paid heroku app performance
What's heroku's official stance on users using various methods to prevent dynos from being idle? I personally have a production app that only uses 1 dyno and need to wait a while for the first request to get processed while the dyno spins back up. While I understand Heroku's reasons for spinning down dyno's that are not being used, I also have heard that slow responses from a web site will impact search engine ranking (faster responses are better). I think this may have been mentioned already but is Heroku planning on offering an "add-on" in order to prevent spinning down dynos for a nominal fee? This seems like a no brainer since users are going to use other methods to keep their dynos alive anyway.

Re: free vs. paid heroku app performance
Can't you set something up to request a page on the app every so often to simulate traffic? I ran into the same issue on Google App Engine and did this to prevent the resources behind my app to not wind down.

Re: MongoHQ + Sinatra
I use something like the following:
db = Mongo::Connection.new(ENV['DB_HOST'],
ENV['DB_PORT']).db(ENV['DB_DATABASE'])
auth = db.authenticate(ENV['DB_USER'], ENV['DB_PASS'])
if auth
puts "authenticated"
else
fail "failed authentication"
end

Re: EXIF support on Heroku?
A pattern I've adopted is to host a worker on a non-Heroku server and wrap it with a RESTful api via Sinatra or use RabbitMQ if you need something more robust. -Shane On Tue, Jun 8, 2010 at 10:15 AM, Patrick Crowley wrote: > Has anyone been able to extract EXIF information from photo uploads on > Heroku? > > Most EXIF parsing gems are wrappers for libraries that aren't > available on the Heroku stack.
