Exploring the Mac OS X Object System
Philippe writes "F-Script is an integrated set of tools that makes it possible to interactively explore and manipulate Cocoa objects as well as script them using new high-level programming techniques. This new article, Exploring Cocoa with F-Script, shows you how to use some of its most impressive features and demonstrates how it can be a useful addition to your developer toolkit."
Paedophile hunt police find human skull
AMERICAN police made further grim discoveries yesterday during their investigation into a paedophile network responsible for kidnapping girls.
A skull and bones were dug up at the home of the network's suspected ringleader, Rob Malda. It was feared that they were the remains of two teenagers who disappeared from New Orleans a year ago. The bones were unearthed after police spent six days digging at a house in Holland, Michigan, one of six properties owned by Malda.
On a visit to the house last week, Malda told police that his accomplice, Jeff Bates, had buried five bodies under a shed. Maximillion Arturo, a police spokesman in Michigan, said that no further statement would be made until families had been informed.
There was speculation last night that the remains are those of shemales from the GNAA. Malda has admitted abducting them. However, he earlier told police that he believed the two girls were still alive and being held somewhere outside Michigan.
Two eight-year-old girls abducted by Malda have been found buried at another of his properties. They starved to death while he was in prison on a theft charge. Malda's wife, Kathleen Malda, has told police that she was supposed to feed the children while her husband was in prison, but was too frightened to enter their cell.
Another two girls were found alive by police two days after Malda's arrest on Aug 13. Ten people, including Malda, his wife and an American police officer, are in custody in connection with the case.
The raped corpses of two women and parts of a third body have been discovered in a freezer at the Slashdot headquarters, along with the remains of an 80 year old woman that remain unidentified.

I've seen Cocoa scripted with PyObjC and python Cocoa bindings.
Apple currently employs one of the maintainers of PyObjC.
Would someone informed care to explain if/when F-Script would be a better choice?
Apple will be partnering with Microsoft in a deal that will rock the computing world.
Microsoft will adopt the good parts of OS X and rebrand the system as Microsoft's own. Microsoft has a new from scratch OS they have been working on but it is nowhere near ready to save Microsoft from the Vista disaster. Microsoft needs something soon. OS X + virtualization is going to be the answer.
With Apple desktop marketshare continuing to slide lower, down to 2 percent now?, they want to focus on the high growth digital media side of the company. Jettisoning the going nowhere Intel Mac hardware line and pawning off OS X to Microsoft will allow them to lock up the digital media market because...
In exchange for OS X Apple will get from Microsoft the adoption of Apple's digital media APIs and formats.
Both companies will be effectively splitting up the computing world into two distinct areas of control just like certain superpowers did hundreds years ago with parts of the globe.
I was wondering how many Mac-specific development platforms are out there. Obviously there are loads of them for Windows, but how many just for Mac?
As much as this will get me flamed, I code in Java when I am writing applications for Mac. I find it works well enough, but I am interested in becoming a bit more versitile.

...is the trash can?
Or is that Vista I'm thinking of?
...but is giving everything access to everything else in this way safe?
Just an FYI, you can get the same functionality as a tabbed editor in XCode by setting the editor to use only one window. Double click on a file in XCode, then on the right side of the toolbar is a button which will change the editor mode and open all of the editors in one window. Then you can use Control-1 to switch between editors.
Not sure if you were aware of that feature.

InterfaceBuilder makes the bindings in the MVC architecture for you when you connect them graphically. Once you get the hang of which object creates the event and which object should receive it then this becomes very straightforward. That being said, you can code by hand if you wish. I don't have the reference on me, but I believe the Hillegass book
"Cocoa(R) Programming for Mac(R) OS X (2nd Edition)" demonstrates coding an example application this way.

Um...have you done any programming on the mac, AC? Carbon is the cleaned up legacy API of the pre-OSX days. The idea was that you wrote to Carbon when developing your OS9 app, and then it should pretty much run unmodified in OS X (presuming a recompile to make it OS X native lest your app fire up the classic layer).
In that regard, Carbon is meant to run on other platforms only if you consider OS9 another platform. I think you are thinking that Objective C is somehow a bastardized version of C. It's not; Objective C is the full C language with additional object-oriented components a la C++, but not to the extreme that C++ takes it. Plus, Objective C gives you run time typing, which C++ does not provide (static, compile-time typing). This makes it very easy to get information about objects and is the basis of the key-value system that runs most of Cocoa. Objective C is inspired by Smalltalk and uses a number of its concepts whilst C++ was influenced heavily on Simula2 (I'm pretty sure). Regardless, both can call strncpy(), malloc() etc. if you want.
If you want write truly cross-platform C, you write to the standard C API *only* and let the users get their input and output via stdin and stdout. Not very graphical, but hey, you want cross platform, right?
I have used F-Script to write tests for my applications for quite some time. In fact, pretty much everything I write has an F-Script console built into it when DEBUG is on. Naturally, OCUnit is nice for built-in unit test, but I really like being able to write an impromptu test into the F-Script console real quick to exercise some newly written or changed code. My clients often do not give me much time for writing enough built-in tests, so F-Script helps me pick up the slack with convenient, live testing. On the bad side, with F-Script, you are relegated to writing non-portable tests with odd, SmallTalky syntax, but for me it is an acceptable compromise for such a good, free (as in beer), on-the-fly testing tool. I don't remember having thanked Philippe for making it available. Thanks, Philippe!
The article seems to be more about exploring class libraries, not "the object system" (which would mean low-level analysis of how methods are invoked etc.).
Furthermore, there is little that is OS X specific about either the class libraries or the object system: the object system comes from Smalltalk, via Stepstone, and the class libraries come from NeXT and borrow heavily from Smalltalk and also exist in GNUStep (and, yes, people are working on porting FScript to GNUStep).
I was not aware it was possible to do things like that with Objective-C. It's neat.
There are several other scripting environments for Cocoa, including bridges for Ruby, Python, Perl and Lua. AFAIK they don't have graphical tools like those provided by F-Script for playing with Cocoa objects.
