Apple Drops Mac OS 9
Eugenia Loli writes "MacCentral has the up-to-the-minute updates on the Apple WorldWide Developer Conference. The first big news is that Apple drops Mac OS 9. 'It's time to drop OS 9,' Steve Jobs said. 'We can do things in X that we just can't do in 9... a hundred percent of what we're doing is X only. [...] Mac OS 9 isn't dead for our customers, but it is for developers. Today we say goodbye to Mac OS 9 for all future development,' said Jobs." We all expected this to happen sooner or later, more sooner than later. There's been no new Apple development for Mac OS 9 in some time; only maintenance updates. But I won't stop Mac OS 9 development. You can't stop me! Muahahahaha! Update: 05/06 18:31 GMT by P : More news from WWDC continues to roll in.
Eugenia Loli writes "Probably the really big news is with Jaguar, the codename for Mac OS X 10.2. There is handwriting recognition technology that will be recognized by any application that uses text. Apple also introduced Quartz Extreme, which takes the compositing engine in Quartz, and accelerates it in graphics cards, and combines 2D, 3D and video in one hardware pipeline via OpenGL. 'Everything on the screen is being drawn in hardware by OpenGL.' It requires AGP 2x and 32MB of video RAM. It is not possible on older graphics cards like RAGE 128 cards, said Jobs -- that means it'll work on newer iMacs and eMacs, but not on older machines, he emphasized. Jobs said this puts Apple two years ahead of 'the other guys.'"
Update: 05/06 18:46 GMT by P : An anonymous user writes: "Apple is releasing Mac OS X Rackmount Servers. Also releasing AIM-compatible messaging called iChat; you can create buddy lists of anyone on the local network, and you can use your mac.com username to log in to it."
Rendezvous. Dynamic IP discovery. Lets computers "dynamically discover each other and share them." Proposing as a new industry standard. Jobs cited example of multiple Macs working at home sharing MP3 files with iTunes between multiple computers. Demonstrated example of MP3 files streaming over AirPort. Works with any IP-ready device; built into Jaguar and will also be offered as an open industry standard that can be built into specific devices.

This makes huge sense for Apple: their future is Mac OS X and the company has been saying this for some time. I'm glad they are making the cut now, still relatively early in the new OS's life cycle. This will help push developers onto the new platform; in turn this is good for end users because the applications they need to run are more likely to appear on Mac OS X.
And again it shows that Apple are able to make gutsey decisions and lead the market rather than follow it. Whatever you think of the relative merits of X vs. 9, this is the kind of bleeding-edge decision making that Apple needs if it is to differentiate itself from the Windows platform.
Sailing over the event horizon
Down inside, the original MacOS was a lot like DOS - single-application, single thread, and no memory protection. Over the years, multiple applications were retrofitted to the thing, resulting in a horrible mess. CPU dispatching was the worst part. "Cooperative multitasking" wasn't enough. But instead of putting a real scheduler, all sorts of "tasks" (timer tasks, vertical blanking interval tasks, system tasks, deferred tasks, multiprocessor tasks, Open Transport tasks, etc.) were added over time. Each of these had a different set of restrictions on what it could do. It would have been far simpler to put in a real CPU dispatcher early on.
Better late than never, I suppose.
O.K. Moderators have your fun with me, but I can't help but comment on the new OS 9 icon where the only story under the topic is the end of OS9. Wouldn't this be better placed under Apple:)

Dropping OS 9 has big implications on developers.
For our Mac version of the product, we had just decided (last week!) to drop support for Mac OS 8.6. Carbon on 8.6 was a major pain.
By going 9-up only, it'll spare us about 4 weeks testing.
Now that Apple itself is dropping support for Mac OS 9, it'll be easier on us to talk about dropping 8.6 support.
We'll continue supporting Mac OS 9 for this release, but for the next release, we'll have ample munitions to entirely drop classic Mac OSes. That ought to trim the application code by about 10%, and accelerate the runtime because of all the IF X switches in the code.
Might not sound like that big of a deal, but when your networking stack checks, at runtime, which layer you're using (Mac TCP for 8.6, OpenTransport for 8.6 up to X, and BSD for X), this really adds up. Let alone all the Classic vs AQUA UI tweaks.
Out of curiosity, I just grepped our sources for this specific runtime switch. There are 87 occurences of it!
"I wonder if anyone is masochistic enough to attempt run an old 68xxx application in emulation mode in OS9 while running that under classic mode in OSX :"
I just couldn't let this one pass by unchallenged. My first Mac was a Quadra 700 and the software I used then was WriteNow (68K Assembly ), FoxBase+ (68K) and I added
Cyberdog as a browser with OS 8 on my PM6500. All run flawlessly under OS X 10.1 on my G3 400 PowerBook. In fact they a much more stable and I don't notice any
difference in speed. My hat off to Apple Enginerring. An incredible feat of backwards compatability.
What really got me excited today was the news about Inkwell, the handwriting recognition engine for 10.2.
I'm excited because it's so useless. There is no way that Jobs would put his people through the effort of bringing handwriting recognition to OS X unless it was a precursor to the iPad. My guess is October, January at the latest.
Soooooo happy.
