A Carbon application uses a revised set of the Mac Toolbox, the original APIs of Mac OS 9 and prior. These APIs are generally designed to allow porting of existing Mac OS 9 apps to Mac OS X to take advantage of Mac OS X's stability, memory protection and other things. You can make Carbon apps so that a single version of an app works on either Mac OS 9 and X.
A Cocoa app works much like a Carbon app except development for these apps use Objective C, C++, or Java. The advantage of a Cocoa app is that you can port this code to other platforms, and it gains some feature advantages in OS X that Carbon apps do not yet receive. Cocoa apps can only operate in Mac OS X.
A true developer here can probably explain more of the particulars that I can, but that's the nutshell.

OpenGL is OpenGL. QuickTime is QuickTime. And DirectX tries to be everything at once.
I'm getting quite tired of this "Macs have fewer games" bull. Many PC game players and makers may not realize it, but Mac game players use PC game players as their "beta testers.' There are LOTS of PC games because its TOO easy to develop a game. Just because there's a ton of copies of a game doesn't mean it's a good game. A threshold of sales there has to be made. When that threshold is reached, a Mac port is usually considered.
The best games from the PC are ALMOST ALWAYS ported to the Mac side. With a few notable exceptions (Half Life, Tribes) I play Diablo 2, Deus Ex, The Sims, the Tomb Raider series and many more titles. Portability is not the problem when you isolate the DirectX features to help the Windows port while using Apple's game support and any QuickTime feature for the Mac, and other resources in the *nix port. At the same time, using common platform tools such as OpenGL help. DirectX is not a panacea--if a developer knows nothing but it, then his games are going to suffer. A ton of PC games that sit in the bargain basket at CompUSA proves my point every day it stays there.
And yes--I could make a PC game from my Mac using a simple IDE such as REALbasic, which works much like VB. Porting from that IDE is child's play because you develop for both platforms simultaneously.
The whole point to a good OS development platform is that you can use one platform to develop for ALL. The Mac "market share" BS does not apply in this discussion. If you disagree, try developing a Java or C++ app on Windows with ONLY the software provided in the retail or OEM release and get back to us. You can't. Mac OS X, as with any good *nix distro, contains a full suite of dev apps. Apple's are notable because they give you a full-featured IDE, not just the compilers.
Mac OS X contains EVERYTHING necessary to write for anything right now. And yes, its a new OS and Apple hasn't documented everything with crystal clarity, but this is the first OS I've noted with intraplatform compatibility not only at the desktop level, but the developer level as well.

Good points about encryption. I like the Arthur Andersen philosophy. Sounds like that's what they were doing for Enron until recently.
As far as document retention goes after thinking--perhaps keeping electronic records is more hazardous than paper. Electronic may have one advantage--it's easier to hide, particularly if you're not using Windows technology. A UNIX OS should be a good way to keep private things private--but, true, it won't stop cops or make the justice happy.
Many companies discourage archiving seemingly trivial things such as e-mail, which can bite in the butt later (Microsoft apparently didn't have such a policy during their recent litigation).
The sad part is that Microsoft technology makes archiving all too easy (Outlook/Exchange personal folder files, for instance). Even basic Internet POP/IMAP stuff is too easy.
If you don't mind, I'm going to steal this and tattoo it to the next post that tries to win the OS X vs. Linux pissing contest.
If I had only one dissent--OS X may only be at present a single, yet versatile knife, but it will soon have attachments and future uses that Paul Popeil could only imagine.
As of this post, CNET News is running a 13 part article on "visionary" people in the IT industry. Fiorina is listed on this, as is Steve Ballmer of Microsoft and a handful of other forgetables.
Yet Steve Jobs, who critics and pundits agree has great vision and has molded and changed the PC community dramatically despite the fact his computer does not make actual PCs, isn't listed?
And Carly has been with HP for about 2 years and hasn't really made any significant impact there beyond driving their stock price down.
HP makes decent printer hardware (except that POS OfficeJet series, which I own) and its PC hardware (which I worked on for 2 years) is adequate, albeit unremarkable. Perhaps Fiorina's departure could kill two birds with one stone--HP's PC business (so they can concentrate on what they do best--printers) and Compaq (whose PCs are among the rattiest things to maintain in the market).
Power Mac G4 systems have an AGP slot, and I believe all systems, desktop and laptop, include AGP. Can't tell you if this is 2X or 4X at this time.
Yep, sometimes I wish Apple would buy Sun, or Sun would buy Apple, and then SGI would grab them--each company has the right idea about making a powerful (as opposed to "fast") computer, but have problems in getting popular leeway due to people who only "know" Windows.
EVERYTHING in the computer community (Mac or store-bought PC) is proprietary. Most people assume that "proprietary" in terms of Macintosh means "closed box" or "non-PC," and this isn't the case.
PCs, in their ultimate basic designs, are supposed to work identically--to be a clone. A hand-built PC (like the Athlon box I just built to play what few good games which come out that aren't available for Macs, such as Age of Sail 2 [rocks] or Half Life) is great, but unless EVERYONE used the exact same motherboard and parts from the same manufacturers, they aren't strictly clones. Technically, your home-built is unique and closed to others--proprietary, because only YOU know what's inside it.
And look at store-bought PCs, which are supposed to be clones, but each manufacturer adds a widget or two here and there to add market appeal over other competitors PCs, which also do the same. If you haven't tried to install Windows on a Compaq without using Compaq's own CDs, you have never experienced the true meaning and heartbreak of "proprietary."
And Macs aren't even "closed box" anymore. As far as the iMac goes, Apple doesn't expect you to crack open your iMac anymore than Toastmaster expects you to crack open their toasters. It's for a logical reason (the same reason why you pay a bit more for a Macintosh): Everything you need is already there, from the laptops to the desktops (extra RAM and maybe drive space included). Thinking a Mac is proprietary is like thinking that your Porsche needs a V8 and one of those Calvin-pissing-on-a-BMW logos.
With the exception of the logic board (motherboard), open a Power Mac desktop and you'll find the same Matrox IDE drives, the same nVidia video, the same SDRAM, and similar expandability. The only difference (OS aside) is that the computer is integrated with finer quality than that $50 ATX motherboard we grabbed from "Chips-R-Us." That's what we pay for.
If you use Linux (and I know most of us do), we experience the sheer hell of PC propriety every time we try to install an OS on a store-bought system that's been modified to work with Microsoft Windows and not for any other OS, period.
Remember the old days where every computer maker made a PC and their own OS? Only Apple does that now for mere mortals (Sun, SGI, and other unique non-Windows PCs excluded but acknowledged). Makes me still wish someone would make a PC designed only for the ultimate Geek--the Unix family user, to end this argument.
/.
The best realization (I think) that Linux/UNIX aficionados have begun to really appreciate Mac OS X will be when you see more iBooks and PowerBooks with OS X showing up during the LinuxWorld trade show.
They chose a platypus because of the "Darwin" name--an "evolutionary" (if not revolutionary) variation on FreeBSD. The BSD little-devil additions to Hexley also pay homage to OS X's roots.
If Apple sold Mac OS X without their hardware running it, it wouldn't be a Mac--and it would show, greatly.
Think of the little inane things that piss you off on any x86 hardware running ANY operating systems it supports. Many of these little things don't EVER occur on an integrated system like SGI IRIX or Macintosh, leaving you to worry about the big stuff--making things or doing something that appeals to you.
You don't buy a Mac for the cost anymore than you buy a BMW or Jag or Porsche for its price tag. Most people expect quality (and receive it) when they put in the extra dollars for a Mac. A PC is built by the lowest bidder, friends. That's OK if you can make it work--but most Joes just want to sit down and play, and the Mac has consistently done that more than any PC I've serviced for my customers.
At the same time, I tell them that I'll build them a great PC if I know they need any computer. Mac zealotism is sooo 1990 and we don't need to play that stupid game anymore.
Hell, we all know how well Windows runs, anyway. Hard to think that POS really HASN'T been hacked for terrorist purposes since its inception. It's certainly kept quite a few of us hostage already!:)
I just helped to write a Mac OS 9/X beginners programming book as well (yes, it really is a shameless plug) using REALbasic as the basis that people who are considering jumping into Mac programming can look into. It only touches on what Cocoa programming is and isn't really a good book for that--the book reviewed here is probably a good start for Cocoa.

The SuperDrive is Pioneer's DVD-RW/CD-RW drive. It does it all, including burning of DVD video (up to 2 hours with iDVD 2, Apple's free software for assembling video with a DVD interface that works on any DVD player or DVD-equipped computer).
There's still lots of infighting for standards, and the SuperDrive is list priced at $899, so I wonder which is the better bargain. "Combo" drives (plays DVDs, read/writes CDs) are used a lot with Apple hardware, and should be easily available for PCs, so I wonder what makes this drive so special.
No amount of faith (important, to be sure) will stop one of several very, very large rocks in space from annililating (that's "destroy" for you Windows users or left-wingers) all advanced life on the planet. That means you, pal.
God helps those who help themselves as best they can--and I believe that means we need to watch out for the one thing in space that can make a very big difference in the lives of everyone, barring some new revelation in space science.
NASA gets less than 1/2 of 1 percent of the budget. The Congress has given more money in international aid to what turned out to be a booger on a map!
Harmonize the environment, my ass! We DO need to watch what we burn and what we dump, but this is a matter of "save the humans", not the Earth. This place will keep spinning no matter how many rocks or PCP barrels land on it. The difference comes when we balance our use of technology--not forsaking it, but not worshipping it, either.
The dinosaurs are gone because they couldn't stop a rock's fall. We really can do better, or we're just as stupid.
I bet you go to college right now, or very recently. Your post is not based on the harsh reality of the world.
And, oh--it was the freaking scientists that you scorn that created the technology that allowed you to post here. Don't be a hypocrite.
Actually, OS X _is_ open source and distributed as Darwin (http://www.opensource.apple.com/). You don't get the OS X interface, but Linux heads would install XWindows on it anyway. It's source is for Mac hardware, but an x86 port is available, too.
Try actually doing some reading before you open your mouth about things you don't know and that are so obvious to know.
And don't use the "proprietary" word until you try to install Linux on most store-brand PCs. The hardware modifiications that some companies do for market differentation make their PCs the most proprietary POS on the planet, incapable of running most OSs well except their customized version of Windows.
The only good PC is a homebuilt. The only good alternative for non-Windows OSs is Linux or BSD. The best alternative for a hardware/software mated *nix commercially _might_ be Mac OS X, but it's way too early to make that claim.
QuickTime was the only way to see the Episode I trailers because it was the only video format with good quality that would work reliably on ALL computers.
Too bad that Apple has decided to get greedy to get people to buy QuickTime Pro, however. Unless you're going to edit movies and sounds, you don't need it.
Next time someone says that Macs or their technology are proprietary, I'll ask them to install a retail copy of Windows NT on an IBM ThinkPad without it exploding...
Come to think of it, try installing Windows on anything except a homebrew PC without exploding (you or the computer)
The TV show was "Salvage 1", with Andy Griffith, who, in the pilot, led a team of ex-NASA people to fly a homebrew spacecraft (with a cement mixer as its life support command module) to the moon.
And NO, I didn't hit the link from imdb. I'm a GEEK. That's why I'm here.
