Using a proxy for NSURLConnection
Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings?

Performance considerations when mixing C++ and Objective-C in same file
I have some high-performance C++ that I need to interface with Objective-C, is there any performance penalty to just dumping this code into a .mm file that contains my Objective-C code vs. leaving this code in a separate .cpp file and extern-ing all the functions I need to call from the .mm file? ...
(Not So) Silly Objective-C inheritance problem when using property - GCC Bug?
Update - Many people are insisting I need to declare an iVar for the property. Some are saying not so, as I am using Modern Runtime (64 bit).
