Re: [Haskell-cafe] Google Summer of Code Proposal - Communicating with mobile devices
Hi, Thanks for your feedback! I have presented the proposal, and now I have to wait for a response. I want to let you know that I have already replaced the code for an English version. You can see it: https://github.com/MarcosPividori/Yesod-server-for-GCM I hope it will be more useful now! Thanks, Marcos 2013/5/4 Kristopher Micinski krismicin...@gmail.com Marcos, Great to see you've revised a copy of this. I've often felt that push communication to devices has a very continuation-y flavor, and I think having something in a web framework to express this would be great. It looks like a large part of your time may be spent developing demo apps, which is too bad, since ideally (for a Haskell project) you'd want to spend as much time as possible writing in Haskell :-). Perhaps you could write a fleshed out demo app for one environment (iOS, Android, etc..) and then shallower examples for the rest. (In theory of course, you don't even need to write sample apps for most platforms, since the push API should be an abstraction layer above that...). Should this project make it through to be one of Haskell's GSOC projects, I'd be happy to chat with you about your development.
