NSXMLDocument outputs numbers in exponential format?

I'm working with NSXMLDocument and serializing it to a file... The issue is the serialized output contains numbers in exponential formal, i.e. installKBytes="1.744E3". Other programs aren't parsing this correctly... Is there any way to modify the output to just format the numbers normally? _

Creating new managed object on 10.4 problem

Hey, I have a CoreData project with a schema that I layout by hand in a class (because the schema has to be used in a command line tool.) On 10.5 my code is working perfectly, but on 10.4 whenever my code attempts to create a new object, I get an exception. According to the stack trace it

Adding objects to NSMutableArray out of order?

I'm dealing with some code that returns results out of order, but the results contain the proper index. In the end, I'd like to put them all into an NSArray, but unlike a C array, NSArray doesn't seem to allow me to simply reserve X number of slots and fill the slots as the results come in.

Re: IsBadCodePtr in Cocoa or Unix?

Exceptions vs. pointers to error objects

Re: Questions about Core Data and SQLite

You might want to look into Postgresql instead. It's much nicer than MySQL at doing desktop applications stuff, and you can even "subscribe" to rows and have the server notify you when changes occur. This makes it much easier to keep clients in sync. MySQL is not great for doing desktop app
