When Leopard gets to the very final stages, won't the developers that get the seeds see the secret things? or does Apple hide them some how? or are the developers sworn to secrecy or what? Can someone please answer this question for me??
I can't wait for Santa Rosa and Leopard to be released, because that is when I will finally shed the shackles of Windows and buy myself my first gorgeous Mac (a MacBook)! Forcing myself to wait for them both is killing me though...
In regards to Time machine, is it possible to exclude certain things from being backed up. For example I don't really want to waste space backing up my itunes library songs since they're technically backed up on my ipod.
And, since Time Machine incrimentally saves data, can a lot of changes be saved above the base backup in a small space? How good would a 320Gb drive be to back up around 80Gb of data?
Hmmmm I think there is some odd numbers here. I am an old TV Engineer, and I remember one of the issues with NTSC vs Analog RGB or y/R-Y/B-Y was that NTSC could only display about 4 million colors while component analog could display about 4 times that. I also know that LCD panels were even more limited.
I think that since we have gone digital, we have gotten used to far fewer colors. This was made possible since the human eye is reeeeeaaaaalllllyyyy adaptable to adjusting to color and not telling the brain about it.
I could see the need for component 10-bit digital and it truly surprises me that with such technologies and the draw of FCP, that the Mac does not natively support this without special drivers.
In my opinion, this locks OS X into being a good platform for DV ( 4:1:0 ) and not native D1 or better ( 4:2:2:2 )
I hope Apple fixes this in Leopard or better.

I have not heard anything about any improvements in color management in Leopard. However, I am not sure Leopard actually needs much improvement in the operating system itself; Tiger (and I think Panther as well) supports many color spaces (including Lab) for use in programs through Quartz. I am also pretty sure that floating-point values are used to describe these, so I am pretty sure that the possible detail level is much higher than 8 bits per component. In addition, ColorSync allows 16 bit per component information. So, there may be no lacking at all in Mac's color management innards, but instead in the software that uses it.
It should be noted, actually, that color management is still much better on Mac, I believe, than it is on Windows. Correct me if I'm wrong (been awhile since I've worked with Windows color stuff) but doesn't windows only natively support 24-bit and sometimes 32-bit per pixel RGB (meaning 8 bit per component)? So therefore it is not Mac which is inferior to Windows, it is the software written for it.
Basically you can do this but instead of just photos, you back up your whole system onto an external HD for example, and then if you want to keep the exact same system you have now, but also the copy of one document saved e.g. two months ago, then you can just save that one file.BTW, what is Time Machine exactly?
I know Windows Vista supports shadow copy natively, where it can save copies of previous versions of the files you use. For example I open up a photo, change it a bit and then save it. If I don't like the edits I can go back to the older copy and work from there.
Is Time Machine something similar?
I think it would be cool that versioning software is builtin to the OS.
As a former system adiministrator, I hated to look up old back up tapes to find files that that the employees screwed up and wanted the original verseion. So something like this would be a good thing.
I think as far as color accuracy, you may or may not get the right colors on your monitor, depending if your video hardware supports overlays (most cards do, I don't know if MacOS X uses that though).
Today AMD/ATi video cards (and maybe high end nVidia cards) do support 10 bit output so if you connect an HDTV to it, you may be able to double check your work as is. However, the OS is still limited to 8 bits per component natively.
As for NTSC, the NTSC standard from 1953 is a pretty large color gamut. However, what is commonly called NTSC today is really SMTPE-C which has a gamut comparable to sRGB. NTSC(1953) is better than SMTPE-C except for some light greens and dark blues and purples.
Right, and the human eye can't perceive beyond 30fps either.In reality, banding is clearly visible with 24 bits for some colors.

Actually... It can... set your CRT to 60Hz and see...
Nevermind.. caught the delayed sarcasm.

Apple also releases the same builds to non-developers through Apple Software Customer Seeding (aka AppleSeed). I've been in the program since the Cheetah seed and many of us test the OS with our own applications and workflow on a wide variety of hardware setups (and do not test the lower level developer related stuff). True, Apple has several branches internally but what they build and then send out are stable milestones to that point with a list of focus areas which we test and provide feedback on. It is a rarity for them to send out builds with a lot of functionality disabled so that we can test out some very specific areas (I recall it was done only once early in the Tiger Server seed).Apple may have several different branches for Leopard, perhaps even separate ones for bug-fixing, features, and the developer preview. The builds that we are seeing are meant to give developers access to APIs so that they can try out new features.
I've read on some other sites about conspiracy theories that they are just seeding fakes to keep developers off guard but if that were true, then this would be defeating the purpose for those us in the customer seeding program using the system out in the wild on a daily basis so that Apple can acquire the necessary feedback to address issues their internal QC engineers cannot find via their battery of tests. Apple will release the stuff they are still hiding when they feel it needs to be released to allow us to test.
That's a scandalous statement. Anyone who works with color and printing knows about the CIE LUV/LAB chart that shows the gamut of average human vision. A typical display only shows about 2/5 of all possible colors that a human eye can see. While a video card can provide 256 shades of color per component, a lot of the viewable colors will be repeated because of the limitations of the display. Also contrast is another issue that needs to be addressed. Our eyes have incredible dynamic range, a monitor doesn't. HDR displays can use the extra bits to encode brightness levels (or more colors that appear brighter or darker).
It is true that our vision is limited to about 2 million colors, but what you see on screen is cut to about 800,000, maybe less, assuming a fixed brightness level.
Just to clarify, we were talking about software limitations of color reproduction. Simple fact is that human eyes do not see beyond 24-bit (10 million colors). What you are talking about is the addition of alpha levels. Sorry if I am coming across as pedantic but this is how it is and it seemed like everyone was continuing to spread disinformation.
How primitive and crude your system is! Here, we build big circles of stones that are lined up so the sun shines through them exactly when the seasons change. Very scientific.

Could you guys ever think that the Aperature prediction was a mistake. That the Leapord is all about the big announcement on April 15th. At NAB?![]()

Too many 10.5 rumors to date...
Funny AvSRoCkCO1067, Your Avatar does not look like the Cherry Creek store... Of course, I guess, since there is not one in Golden, you must have to dream of the perfect Apple Store.![]()

BTW, it wasn't on this site the conspiracy theory about Apple possibly seeding fakes. I just find some of that stuff being thrown out on other sites way off from the reality with the way Apple has handled Mac OS X seeding since Cheetah (much more mundane than people think). But yes, at this point in time, the cosmetic related stuff isn't important even for us non-developers to test as opposed to finding and reporting problems with the actual functionality of features in the OS and how a variety of applications work with regards to compatibility, performance, etc since there is only so much Apple can test in their lab (they can't duplicate the wide variety of situations which exist out there). If Apple has UI and Finder related changes in the works but are holding them off for maximum impact, I think it will end up showing up closer to when the OS is nearer to GM (given how quickly actual details of the latest build has surfaced, it is understandable why Apple isn't going to divulge whatever they are keeping secret now in order to get the most bang closer towards release).I don't think Apple is releasing "fakes". I just don't think Apple is releasing everything. They don't really have a need to demonstrate new features such as UIs early. There is not much to "test" here, and not much developer stuff which relies on this.
Based on previous seeds (Tiger, Panther, etc), they've normally been very aggressive. With Leopard for 9A283 and 9A321, engineering resolved a large number of issues I reported but so far, none for the ones in 9A344. They normally are quick to respond if it is already a known engineering issue, ask for additional debugging information, ask us to try a specific set of steps, or if a problem has been addressed, to check and respond if it has been resolved but so far, nothing. This just leads me to believe they are busy working on prioritizing and addressing them which is one possible reason why the relatively small number of builds to date and seamingly large list of known issues.I still think that the main reason which bugs have not been fixed in these newer builds (though I have not seen them, so I really don't know) is that Apple simply doesn't want to merge their branches too often. I think that merging development and production branches caused problems for them when iTunes had resources hinting at the iPhone.
