I'm thinking about developing an app which will make a strong use of geolocation (mongodb will be my choice), and strong upload of photos (and viewing too).
I was just wondering if you could help me with framework election. I've been using node.js for months and I'm very comfortable with it, but because of its one-process nature, will it be bad for locking when uploading big photos?
The other solution I'm working on is rails.
Which one will you choose? Any other ?
Thanks

Take a look at the cluster module, this should help with leveraging more cores. In fact one of the node.js clients on the front page are these guys: Transloadit who focus on handling images.

I've done a lot of work with MongoDB and I recommend reading up on the limitations of MongoDB's geo-location tools. The product does provide some functionality, but it does not match the features of Postgres. You will want to ensure that MongoDB covers all of the features you require before beginning.
With Streaming you can support more then one client during a upload, since the upload will be broken into different parts. I sure expressjs has some good streaming examples.
