# Multi App Dynos

Recently @hirodusk tweeted - http://cl.ly/image/2s1X0E351v29 - about a prototype they've been working on to bring visibility to their dynos idling behavior. He got me thinking. 

What about if we can have a different Dyno that can be share between apps? So far, I've been able to acomplish something similar to this by having a bunch of different sinatra apps and mapping them to different URLS. All this under the same Git repo and Heroku app. This approach is all good if all the sinatra apps are related somehow, but it brakes if they apps are unrelated because you don't want them all in the same repository.

I would love to pay Heroku for 5 Dynos and have them serve 10 different apps.

I still like Bertrand Meyer's advice on exceptions: use them when you 
can't tell before a call whether it will succeed or not. 

That said, there are alternatives.  You can pass two actions to a 
method, one of which is called when it succeeds and the other when it

Hi! This is Ivan. One of the founders of MealsApp.com I noticed you have recorded a lot of meals and I am wondering: - What don't you like and what do you like about the app? - What would you like to see in the app so that it is awesome? Thank you very very very very much for replying to this email. It'll help us create the best app for nutrition. Bon Appetit
