iPhone 'Hello World' Application

iTunes

iTunes is already becoming the Finder. With Cover Flow and Quick Look added to the Finder in Leopard, it seems to me like Apple is positioning iTunes (or at least the iTunes interface) as the new default file system interface.

that's what i meant: the infrastructure is there, so why not use it to center all digital sales in it? i could very well see selling ALL digital content through itunes, i.e. os x updates, as well as mac software, as well as games and anything you can use on any apple product. wouldn't be surprised if the itunes store once becomes the "apple media store"

haha they could rename it iStore!

But, the OS must have hardware memory protection support in order to implement protected memory.

ARM processors have not had protected memory until recent versions, and even so it is an optional component!

That depends on your definition of "Recent". Sure, MMUs are optional on just about the entire family. But there have been variants including an MMU since at least the introduction of the ARM7 generation in 1994. That's when Linux was ported to the ARM. (The real Linux kernel, mind you, not the uCLinux branch that works without memory protection.)

Don't be so quick to say the OS is crap, when it may be running on hardware that cannot support protected memory.

Also, note that preemptive multitasking is another useful feature of the OS, Palm has cooperative multitasking - and we all know how much Mac OS sucked because of that.

And even Palm's cooperative multitasking isn't officially supported for 3rd-party developers - IIRC it has to do with the licensing terms under which Palm originally acquired its OS's kernel.

When one application is displayed on the screen, all other applications are effectively put to sleep and shut down. That counts as single-tasking in my books.

Commercial media players like RealPlayer have been granted a special licensing exception allowing them to operate in the background and continue playing music while another application is on the screen. Other programs use unofficial hacks to do it.

What is a Hello World application?

I was thinking the same thing . . . working my way back in posts to see

TUAW got a good article up by Erica and Rixstep mirrored the code. Don't have the URLs right now but they're not hard to find. I'm especially impressed by how Erica got her own iPhone programmed with SSH or whatever. She built her own toolchain, got advice in IRC, and went for it. WTG!

I do my homework before I use any programs. It really is very easy to find reviews if a app is any good, i.e. 3rd party apps can be just as good a 1st.
