• Managing a user's PHP session with Cocoa Touch

  - by Calvin L

  I'm building an iPhone app, which will allow users to log in to a PHP web server that authenticates the user and starts a session. My idea for managing a session is to create a singleton User class that has a sharedLogin method. Would it be prudent to store the session variable in the shared instance in order to maintain the session?

• Rails - Accessing model class methods from within ActiveRecord model

  - by aaronrussell

  I have a simple standalone model that doesn't inherit from ActiveRecord or anything else, called SmsSender. As the name suggests, it delivers text messages to an SMS gateway. I also have an ActiveRecord model called SmsMessage which has an instance method called deliver: def deliver SmsSender.deliver_message(self) self.update_attributes :status => "Sent" end The above is returning uninitialized constant SmsSender. I'm sure this is dead simple, but how can I access the SmsSender class from within my model?

• How to wire a verifier to a 2.0m5 Restlet using the spring extension and an xml config?

  - by Kevin Pauli

  I can't seem to find any example of how to do this. Imperatively in java it would be a piece of cake of course, but I can't seem to figure out how to inject my JaasVerifier into my SpringComponent declaratively from within the xml. It appears from the method signatures that Verifier is designed to be attached to Context, but the instance of Context itself is created as a side effect of the SpringComponent creation so I can't get a hold of it in Spring. There must be something I am missing.

  Lets say I have two MySQL databases with some complex table structures. Neither database has the same table name.

• Transcoding audio and video

  - by Lance Fisher

  What is the best way to transcode audio and video to show on the web? I need to do it programmatically. I'd like to do something like YouTube or Google Video where users can upload whatever format they want, and I encode it to flv, mp3, and/or mp4.

• Redirect everything to index.php

  - by pixel

  I'm trying to do clean urls by exploding $_SERVER['REQUEST_URI'] and then switching between the results. However, once a user goes outside index.php, I'm assuming I need to redirect them back to index.php in order to process the URL they want to reach. How can I accomplish this? So for instance, user goes to www.domain.com/home/johndoe/... i'd like the index.php (domain.com/index.php) to be hit so that it can process the /home/johndoe/ via request_uri.

• Rhino Mocks - Do we really need stubs?

  - by Marcelo Oliveira

  If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway? What do we lose by always using MockRepository.GenerateMock()? One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward. The moq framework works in a similar way... we don't have different objects for mocks and stubs. (please, don't answer with a link to Fowler's "Mocks aren't stubs" article)
