My understanding was that both Carbon and Cocoa are fairly "thin" (Cocoa being a bit thicker than Carbon) wrappers over the Core OS X code. In other words, these are not two separate implementations, just two separate interfaces into a common implementation. Which implementation is in C (going with the BSD subsystem).

IIRC, "Cocoa" and "Carbon" are APIs, not implementations.

If this is correct, then one can imagine the functionality of both APIs perhaps being made to have more in common (although I sense that the Carbon APIs are stagnating), but one API isn't really built "on" the other, nor would such a re-architecting make sense.

It depends on which parts of Carbon/Cocoa that you actually mean. The interface toolboxes in Carbon & Cocoa are not thin at all, as they both implement the all of the functionality. The event system is based on lower level functionality. All windows are based on a common window API, but each toolkit adds additional functionality over this API. And the lowerlevel Carbon functions (like the File Manager) are based directly on BSD APIs. Cocoa also uses these Carbon functions as well as the BSD layer directly.

What I meant by saying that Cocoa would be foisted over Carbon is just the interface toolbox and the event system. That is all they would need to allow Carbon & Cocoa windows & widgets to coexist in the same application.

As for Carbon, it is not stagnating, but in fact growing to gain much of Cocoa's functionality, as evidenced by a number of Carbon oriented sessions at WWDC.

I may have been at that session. If it's the one I'm thinking of there was a chart showing the major components of PB, along with the lines of code in each. The large majority was ObjC, but there was some C++ (don't remember for what).

Note that there is a distinction between a Cocoa app and an Obj-C app...It is very easy (and IMHO natural) to graft a "Cocoa" front end onto a core business logic centered around a C or C++

Good point. This is how we get a lot of ported Unix apps like vlc and mplayer. While I have no direct knowledge, I would expect Apple's ObjC development to be more "pure".

Actually, we do know that the 750GX exists, at least on some drawing board somewhere, as there is a document from IBM that mentions it (I don't have the url to the pdf handy right now...), but it is only mentioned in passing and gives no technical details. So, what the 750GX is is a matter of rumor, but that it exists is not.

On the other hand, the PowerPC 7457 is still around the corner, I've found some new references :

PowerPC 7447/57 compared to the other G4s.

PowerPC 7455/57 benchmarks includes SPECint_base2000 on a PowerMac 1.25 GHz running Linux.

AltiVec tuning

Older material with power comsuption 7.5W @1.0 GHz, 16.6W @1.3 GHz (typical)

Now whether Apple is gonna use it or not, is another question.

new powermacs

I think that at the WWDC we will see something pretty amazing. Do you remember when Jobs/God said that this year would be the year of the laptop, well, I know that everybody remebers that. But maybe what the big new thing that will be announced is a dual or prehaps, a 970 powerbook. I think this because it hasn't really been that big of a laptop year, but what he also said and the article about the number of powerbooks in Britain is growing above that of powermacs. So what if Jobs was teasing us in January, and then in the summer we will see a new line of macs, where the powerbook is the new pro machine. Maybe. . . I mean the new book iss 17in and that is the size of most of the displays that people get, also it's on the iMac. What if the new secret project has a special dock so that you can trun it into a major station, like the XServe. And also does anybody rember the post on the new caseings that were being made, the were like some kind of metal that was supposed to chemicaly etched, and those posts about the machines being like The Cube (The first desktop that I owned, but majorly testy, the touch buttons, weren't like the ones on the new pods, but would react to what ever touched them) but able to be networked together and have the ability of joiattaching to one another so that you could have as many processors, and as much speed as possible. I don't know maybe this is just a waste of space, but I am almost positive that the new direction that apple is going to go is with superbook, and then the old iBooks, would become what the powerbook is now, and then the iMac would be more or le3ss the powermac, but available in a range of speed, for people that want a desktop. In summery, I guess I think that Apple is going to majorly transforming, what the accepted generic build of a desktop is going to be totaly differant than anything that we can imagine, it will be something that revolutionizes the industyr, something that micros, will drool over, and rock our minds.

Despite this information, I am very dubious about the 7457. Even if Moto were shipping these processors now, I really don't trust Moto not to mess up somehow. I honestly hope that Apple gets away from Moto ASAP. After all, Moto has made little secret of the fact that they want to be out of the desktop processor business...

I honestly can't see Apple doing this. There are still professionals that need to be able to configure systems with custom interface boards and that sort of thing, and if Apple did this they would be permenantly shutting themselves out of this portion of the market. It's not always about speed and number of processors. Sometimes it is about how flexible a machines configuration is, and that is something that the tower design offers which simply cannot be achieved with more FireWire and USB ports...
