That's true, but Objective-C is a 30 year old langage, if Apple could rewrite it from scratch it would probably be more elegant.

First line :

CIContext *context =
[CIContext contextWithOptions:
[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES]
forKey:kCIContextUseSoftwareRenderer]];

=>

CIContext *context =
[CIContext contextWithOptions:@{@kCIContextUseSoftwareRenderer:@YES}];

I'm lazy to rewrite the complete sample but it could really look as the C# sample because Objective-C has evolved since 10 years ;P

I think your problem comes from Firefox. Firefox uses his own file associations database, and Firefox sometimes forgets to refresh its file associations database when something changes in your system. Try it with IE or Opera to be sure. I think Quicktime has nothing to do with that. ;)

You can search for a deleted contact in your address book and Vista/2003 searches the correct previous version of the address book file ? No. It doesn't exist in Vista/2003.

And that's written by people using Microsoft software... :zzz:

I am astonished because the OS9 compatibility layer works perfectly and is very fast. The first starting of an OS9 application starts the OS9 compatibility layer in approximately 15 seconds on an average Mac. But perhaps that this Tech guy used a very old version of OSX ?
