Facebook asking you to rate Places

I just noticed this, not sure if it’s new or part of their A/B testing. They’ve got a box on the right hand side asking which of two places I have previously checked into was better. It looks like Facebook are trying to gather information about places so they can provide recommendations, much like foursquare’s Explore tab. Have any of you noticed this on Facebook?

Core Data not returning a custom concrete class

Ever had a problem when you’re fetching something from an NSManagedObjectContext, and you’ve set a concrete class in your model, only to find that it is an NSManagedObject? Me too.

binding not implemented for this SQLType 7: Core Data and iPhone OS 3

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'binding not implemented for this SQLType 7' That’s not something you want to read. And it doesn’t make much sense. And there’s not a lot out there on that problem, either. I am adding Core Data to Zoopcast (the people-powered local search app). The first few releases just took data from the JSON web service, and put it into unmanaged objects. (As it turns out, I probably should have Read post »

Azure Full IIS: RoleEntryPoint runs in different process to web app

I just found this one out thanks to this post from the Azure team. Basically, I was configuring Table Storage (as you may have guessed, if you’ve read my other posts today), and using the CloudStorageAccount.FromConfigurationSetting(string) method. As you are probably aware (if you are aware of this sort of stuff), to be able to use that method, you must first set a function that tells Cloud Storage how to figure out how to get configuration settings.
