Brief background: I'm porting an audio generation system to Mac OS.
The code for generating audio is in C and has run on a couple of other
OSs. It's been reasonably straight forward to model the parameters for
this system with Core Data, and I'm excited about getting CD to handle
multiple Undo
If I invoke NSSound to play the same sound more than once, without
cycling through a run loop, it only plays the first time, and other
times, fails silently. [1]
If I cycle through a run loop, then it works fine. [2]
The documentation states that NSSounds play in a separate thread and I
Is it OK to perform a fetch during validateForInsert:/

It's not a great idea during validateForDelete: It fine during
I can not find any data structure in Cocoa that maintains sorting
order of items gradually added in, using the pairwise comparison
results, something like the canonical set in C++'s STL that is usually
implemented as a balanced tree.
Thanks in advance.

There's nothing wrong with using Launch Services still. Jut because
it's a C API, doesn't mean it's Carbon and bad. NSWorkspace is just
an Obj-C wrapper round some of LaunchServices.

This is off-list.
You know, I just went through this with the validateKey: bit. I found
that a side effect of fetching during that validateKey was the save

I then tried the performSelector, which worked, however, then the

I don't care the naming style, I care about the functionalities. And
it seems Cocoa is weak at supporting sorting-order-keeping data
structures at the high level APIs.
However, the reference is valuable. Thank you.

I think I have figured out how to make stationary layers layout (stay

either autoresizeMask or the constraints, but I need to do the same for
layers that are moving.

1) If the default implementation does nothing, why must I invoke
super when overriding this method?
You're right, that's confusing. Could be several answers though: maybe
super does nothing visible, but still something; or maybe super could
start doing something in the future. It's better
