Glad I didn't shell out the money thinking it was. 64 bit Maya is going to be nice, I'm think its coming when OSX 10.5 hits. I got Maya 8 but have not loaded it yet.
BTW, I go to the OSX Maya forum once in while and have seen your name there. Is DD the one that got the full version?
Nope, Bernard of course. :D
DD has helped me out a few times with other things.
That's what I was thinking about with leapard. I'm glad Apple is finally offering 64-bit gui support. I really didn't see a need for it, but now that these 3D apps are giving OS X the shaft, I'm eagerly awaiting it.
I would like to try out some of 8's new modeling tools. I'm going to have to wait though, since it's practically full price for an ugprade and I'll be moving to Intel this coming year. I wish Autodesklias had a more affordable upgrade path for small shops. This coming year is going to be expensive and probably buggy.

There's a market for games with more depth that sell at higher prices, and there's a market for cheap on-the-go games that are great for downtime on the train or waiting at the airport.
The point is the line between these two camps is being blurred. It's a feature of the post-PC era. Look at what the App Store games section is evolving into - daily, monthly, yearly. It's pretty astounding. Soon, "hardcore gaming" will characterize other devices in addition to consoles. THIS is the real revolution that's going on when it comes to the gaming market. Apple is redefining it.

Google has stated they will never have a smartphone. At best they just guide (rather closely) companies when producing Android handsets.
That said, if the iPhone isn't on verizon by midway next year with no solid rumors of it coming, I'm probably going to get an HTC Eris (or the Eris II will be out by then). Cheap, sexy, and running a decent OS (which will hopefully by 2.0 by then).
Gooooooooogleee phone!!!

Until Vista and Win 7, it was effectively impossible to run a Windows NT system as anything but Administrator. To the point that other than locked-down corporate sites where an IT Professional was required to install the Corporate Approved version of any software you need to do your job, I never knew anyone running XP (or 2k, or for that matter NT 3.x) who in a day-to-day fashion used a Standard user account.
Of course, I don't know of any Linux distribution that doesn't require root to install system wide software either. Kind of negates your point there...
In contrast, an "Administrator" account on OS X was in reality a limited user account, just with some system-level privileges like being able to install apps that other people could run. A "Standard" user account was far more usable on OS X than the equivalent on Windows, because "Standard" users could install software into their user sandbox, etc. Still, most people I know run OS X as Administrator.
You could do the same as far back as Windows NT 3.1 in 1993. The fact that most software vendors wrote their applications for the non-secure DOS based versions of Windows is moot, that is not a problem of the OS's security model, it is a problem of the Application. This is not "Unix security" being better, it's "Software vendors for Windows" being dumber.
It's no different than if instead of writing my preferences to $HOME/.myapp/ I'd write a software that required writing everything to /usr/share/myapp/username/. That would require root in any decent Unix installation, or it would require me to set permissions on that folder to 775 and make all users of myapp part of the owning group. Or I could just go the lazy route, make the binary 4755 and set mount opts to suid on the filesystem where this binary resides... (ugh...).
This is no different on Windows NT based architectures. If you were so inclined, with tools like Filemon and Regmon, you could granularly set permissions in a way to install these misbehaving software so that they would work for regular users.
I know I did many times in a past life (back when I was sort of forced to do Windows systems administration... ugh... Windows NT 4.0 Terminal Server edition... what a wreck...).
Let's face it, Windows NT and Unix systems have very similar security models (in fact, Windows NT has superior ACL support out of the box, akin to Novell's close to perfect ACLs, Unix is far more limited with it's read/write/execute permission scheme, even with Posix ACLs in place). It's the hoops that software vendors outside the control of Microsoft made you go through that forced lazy users to run as Administrator all the time and gave Microsoft such headaches.
As far back as I remember (when I did some Windows systems programming), Microsoft was already advising to use the user's home folder/the user's registry hive for preferences and to never write to system locations.
The real differenc, though, is that an NT Administrator was really equivalent to the Unix root account. An OS X Administrator was a Unix non-root user with 'admin' group access. You could not start up the UI as the 'root' user (and the 'root' account was disabled by default).
Actually, the Administrator account (much less a standard user in the Administrators group) is not a root level account at all.
Notice how a root account on Unix can do everything, just by virtue of its 0 uid. It can write/delete/read files from filesystems it does not even have permissions on. It can kill any system process, no matter the owner.
Administrator on Windows NT is far more limited. Don't ever break your ACLs or don't try to kill processes owned by "System". SysInternals provided tools that let you do it, but Microsoft did not.
All that having been said, UAC has really evened the bar for Windows Vista and 7 (moreso in 7 after the usability tweaks Microsoft put in to stop people from disabling it). I see no functional security difference between the OS X authorization scheme and the Windows UAC scheme.
UAC is simply a gui front-end to the runas command. Heck, shift-right-click already had the "Run As" option. It's a glorified sudo. It uses RDP (since Vista, user sessions are really local RDP sessions) to prevent being able to "fake it", by showing up on the "console" session while the user's display resides on a RDP session.
There, you did it, you made me go on a defensive rant for Microsoft. I hate you now.
My response, why bother worrying about this when the attacker can do the same thing via shellcode generated in the background by exploiting a running process so the the user is unaware that code is being executed on the system
Because this required no particular exploit or vulnerability. A simple Javascript auto-download and Safari auto-opening an archive and running code.
Why bother, you're not "getting it". The only reason the user is aware of MACDefender is because it runs a GUI based installer. If the executable had had 0 GUI code and just run stuff in the background, you would have never known until you couldn't find your files or some chinese guy was buying goods with your CC info, fished right out of your "Bank stuff.xls" file.
That's the thing, infecting a computer at the system level is fine if you want to build a DoS botnet or something (and even then, you don't really need privilege escalation for that, just set login items for the current user, and run off a non-privilege port, root privileges are not required for ICMP access, only raw sockets).
These days, malware authors and users are much more interested in your data than your system. That's where the money is. Identity theft, phishing, they mean big bucks.

People you seem to be missing the point that the $299.00 price is for FCP and not the entire studio package. Remember FCP was only one of many applications in FCS. I would expect the other applications to be similar priced in the app store. So in the end I think you may end up paying just as much.
What I did find interesting is no mention of upgrade pricing for existing FCS users. How will they handle upgrades per application?
Remember for current users we paid a small feee to upgrade the entire studio package.
As an editor I can say this is pretty interesting. I would expect the same level of precision we are used to now under the hood. I think the main focus of this demonstration was to show the new features and how easy FCP can be now for the non tech people.
My only concern at this point is every iMovie user now thinking they can be a pro editor with no training and very little cost. Even a 10 year old kid will be using FCP. This is going to affect the editing job market and make editors a dime a dozen. Sure talent still matters but it is going to be harder for companies to sift through 5000 demo reels trying to find that talent. Apple has pretty much turned editing into Wal-Mart.
You might as well kiss Avid goodbye as well. I'm sure there will be die hards for the old way of editing but if FCPX can hang on to the precision of a pro editor without the complex overhead then Apple has just sent Avid yet another major blow. Adobe and Vegas are still a bit safe since they had a lot of these features for awhile now. In fact I see a lot of similarities with Sony Vegas. To me FCPX is the way Vegas should have been from what I have seen so far.
Perhaps Avid will finally wake up and overhaul their entire interface the way they should have 4 years ago already. Avid had the opportunity when they bought Pinnacle Liquid to have a NLE with background rendering and other newage features but they killed it in favor of their dinosaur. The new FCPX is what Liquid could have been if development would have kept going.

(Don't be offended if I repeat myself a few times, I want to make sure everyone gets it. Not trying to say anything about you in particular.)
Anyway, you missed my point. I know very well that the G4 is at a hardware disadvantage. I pretty much said that when you see a G4 being beat by margins greater than 4x or 5x, then you can be pretty sure there is ALSO, note ALSO, a software disadvantage. Hopefully everyone will see what I meant that time. :)
I'm glad to see that many people here agree that the G4 isn't really a faster chip than the x86 competition, but I want to see moderation and understanding of the "benchmarks" that have popped up showing an unbelievably bad situation for the G4.
Remember folks, if the test shows a G4 slower than a P4 per clock cycle then the test probably is handing the software advantage to the P4. Note, for perfect clarity, that I said per clock cycle performance and not overall performance.

They joys of an unregulated mobile industry..... being stuck with only 1 (until recently) choice of carrier, 2 year contracts, paying extra for tethering, PAYING for incoming calls (WTF:eek:).
I'm glad I'm stuck in over regulated EU. On the up side, you yanks get to play with all the new toys first :rolleyes:
Actually, you can buy unsubsidized phones and have no contract lock just as in the EU; plus we don't get charged extra for calling a cell phone from another phone - and given the calling plans and unlimited minutes between the same carrier / friends / evenings using minutes for incoming calls is a non-issue for virtually all US phone users - I'd rather have that then have to pay to call a cell phone.

Just to note there is gay behaviour in the animal kingdom, my two male cats went at it in there puberty and it is well documented in other animals. It is perfectly natural and before the time of the christian gods creation gay behaviour was tolerated in Rome though lesbian behaviour was not.
And marriage is legal in many parts of Europe between same sex couples, it is only the 3rd world and developing world that has the biggest issue with same sex marriage but as these countries always traditionally follow Europe expect the decline of religion as more and more people become educated, and with the decline of religion such nonsense as hating each over whom we love to also fade away.

Apple has released a statement regarding the findings and it is just as realiable as Greenpeace's.
Besides, I said that Apple is doing what they can.
and the article says: "...performs poorly on product take back and recycling...
and maybe that's very important for Greenpeace. And I don't even know, if Apple takes back any electronics at all.

I haven't had any dropped calls yet. I think the problem is more the iPhone, than AT&T's network . If I drive out of 3G service my iPhone drops service and says no service on it, doesn't revert to the Edge network most times. I have to turn 3G off or turn airplane mode of then on to get service on Edge. IMHO apple needs to fix the software in order to make the switch to and from Edge and 3G like other phone, no drop in service it just switches over. Sitting at home if I turn 3G on I get 3G signal and speed with 4 bars, but after about 5 minutes it switches to Edge. Any other phone besides the iPhone stays on 3G.

AT&T already gets $50 I'll be damned if I pay anymore for the 1 time a month I actuly need to pull up a full web page due to flash. Yes they get $50 for data, $30 for my unlimited plan (I use ~1gb) and $20 for unlimited texts which is simply insanely small amounts of data.
What contract did I physically sigm when I got my phone? The only thing I signed was a credit card receipt. All you idiots need to read up about Ma Bell and the **** they tried pulling years ago. It's headed back in that direction now.
To all the morons who say if you don't like it don't get it. Your right the carriers should rule over ours lives. We should simply not have phones if we don't want to grab our ankles and like it, every time the phone companies come up with a new way to stick it to us.
Weak minds will continue to be brainwashed by larger corporations site any TOS you want. Your the same people that argued about how AT&T needed 2 years to get MMS to work, and they were right. Probably the same lot that gladly ponied up extra cash to unclock Bluetooth and ringtones on your celluar one / vzn phones.
Well no not quite. Over in the UK I laughed at AT&Ts inability to get the ball rolling on MMS. But if you sign a contract you stick to it. It couldn't be any simpler.
O2 charge extra for tethering, guess what? I voted with my wallet and didn't pay it.

I agree but they will never match real desktops. Technology advances. Something you can do today let's say in 2 hours you will do in 1 next year on new equipement. Thing is that next year you will ramp up the quality of the final product still getting same 2 hour work period. It's like that for ages and will never stop :)
Exactly! Desktop shipments still outpace laptop shipments. Desktops and Laptops will continue to hold top market share, while inevitably tablets will cut into that margin and find a nice place and sit. Desktops have been around since the beginning.. and every challenger to it has never surpassed the market share. Laptops, Netbooks, Tablets, smartphones... whatever.. people still need desktops and laptops for prolonged productivity.

I'm not jailbroken, I don't tether. But it pisses me off that they are wanting to limit data.
I just checked, my data use per month for the last six months is anywhere from 4GB-7GB a month. Mostly because I stream a radio station. Pandora is better at managing data sending it in packets, this app uses straight streaming.
I'll be staying off my wifi at home and at work.

JUST IMAGINE A COMPUTER IN WHICH EACH PIXEL IS CONTROLLED BY A SINGLE PROCESSOR.
I've used one. Back in the 1980s, beginning of the 90s. The low end model had 1024 processors and the high end model 4096 processors. It was a pig to program. When drawing on the screen you split the task at hand up into many parallel threads each drawing a part of the screen. Not quite 1 CPU per pixel but you get the idea.

Wow I missed a lot by spending all of Friday away from this board. I am way behind in posts here, and I'm sure I'll miss a lot of things worth comment. But anyway, the code fragment:
int x1,x2,x3;
for (x1=1; x1<=20000; x1++) {
for(x2=1; x2<=20000; x2++) {
x3 = x1*x2;
}
}
Is a very poor benchmark. Compilers may be able to really dig into that and make the resulting executable perform the calculate radically different. In fact, I can tell you the answer outright: x1=20000, x2=20000, x3 = 400000000. It took me 2 seconds or so. Does this mean that I am a better computer than a G4 and a P4? No, it means I realized that the loop can be reduced to simple data assignments. I have a better compiler, thats it.
Anyway, lets pretend that for whatever reason compilers did not simplify that loop AT ALL. Note that this would be a stupid stupid compiler. At each stage, x1 is something, we ++x2, and we set x3 = x1 * x2. Now notice that we cannot set x3 until the result of X2++ is known. On a pipelined processor that cannot execute instructions out of order, this means that I have a big "bubble" in the pipeline as I wait for the new x2 before I can multiply. However, after the x3 is started into the pipe, the next instruction is just another x2++ which does not depend on x3, so I can do it immediately. On a 7-stage in-order chip like a G4, this means that I fill two stages of the pipe and then have to wait for the results on the other end before I can continue. You see that this is very inefficient (28% or so). However, the G3 is a 4-stage design and so 2/4 of the stages can stay busy, resulting in a 50% efficientcy (so a 700mhz G3 is "the same as" a 350mhz G3 at 100% and a 800mhz G4 is "the same as" a 210mhz G4 at 100%). These are of course simplified cases, the actual result may very a bit for some obscure reason.
Actually the above stuff is inaccurate. The G3 sports 2 integer units AFAIK, so it can do x3 = x1*x2 at the same time as it is doing x2++ (for the next loop of course, not this one). This means that both pipes start one bit of work, then wait for it to get out the other end, then do one bit of work again. So this is 25% efficientcy. A hypothetical single-pipe G3 would do x3 = x1*x3 and then do x2++, however it could not do x3 = x1 * x2 again until the x2++ was out the other end, which takes 4 cycles and started one after the previos x3 = x1*x2, which should mean 3 "bubble" stages and an efficientcy of 20%.
Actually, it may be worse than that. Remember that this is in a loop. The loop means a compare instruction (are we done yet?) followed by a jump depending on the results of the compare. We therefore have 4 instructions in PPC I think per loop, and we can't compare x2 to 20000 until x2++ has gone through all the pipe stages. (Oh no!) And we can't jump until we know r]the result of the compare (oh no!). Seeing the pattern? Wanna guess what the efficientcy is for a really stupid compiled version of this "benchmark"? A: really freaking low.
I'll see about adding more thoughts later.
int x1,x2,x3;
for (x1=1; x1<=20000; x1++) {
for(x2=1; x2<=20000; x2++) {
x3 = x1*x2;
}
}
Is a very poor benchmark. Compilers may be able to really dig into that and make the resulting executable perform the calculate radically different. In fact, I can tell you the answer outright: x1=20000, x2=20000, x3 = 400000000. It took me 2 seconds or so. Does this mean that I am a better computer than a G4 and a P4? No, it means I realized that the loop can be reduced to simple data assignments. I have a better compiler, thats it.
Anyway, lets pretend that for whatever reason compilers did not simplify that loop AT ALL. Note that this would be a stupid stupid compiler. At each stage, x1 is something, we ++x2, and we set x3 = x1 * x2. Now notice that we cannot set x3 until the result of X2++ is known.

(Examples = teaching)!= saying
The latter is specific to the situation.
This quote is sectioned to the event of homosexuality being concerned. However, you have to prove that woman is being obscene, which is almost impossible if you've got to find 1 doctor, 4 witnesses to event, and two family members to testify the same thing.
100 striped != death.
Adultery or fornication is VERY contentious in Islam. It is a big sin, and often breaks contracts, of nature of marriage. No death here.
...
If you're going to quote something, please be sure to complete the damn sentence... and not end it prematurely:
And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance; and establish regular Prayer, and give regular Charity; and obey Allah and His Messenger. And Allah only wishes to remove all abomination from you, ye members of the Family, and to make you pure and spotless.
In other words, be modest.
as above, adultery is a greater sin. This, though, does not demonstrate honour killing. An honour killing is killing made by family or community that the victim has brought dishonour against the family or community.
In this case, is it not dishonour, is it considered to be criminal.
As above.

Glossing over "heat" and "power" with a blah blah blah is probably a bit cavalier. Those are the two main issues facing notebook computers. Desktops have the advantage of infinite possibilities in terms of size, scale, cooling units, fans, and they have an infinite power source to go with it. Notebooks have to balance performance with energy constraints and heat constraints, the latter being the main issue. If you pile processors into a notebook that heat up, that heat has to dissipate somehow, so you're left with two choices: make a bigger laptop with more vents/cooling units (nobody wants that), or allow that heat to dissipate naturally which has limitations. If you ignore those limitations, you end up with a notebook that overheats, and inevitably your drives die or your motherboard cracks from heat stress.
So yes, notebooks are going to start to lag behind desktops more and more as multiple cores start to proliferate because cooling units can't keep up. Yet anyway.Zactly. They already have. I am postponing the mobile purchase until after I have the Dual Clovertown fully operational. Moreover, we can't even see beyond the mobile speed Apple just introduced Tuesday. Intel is giving us no numbers when it comes to beyond 2.33GHz Core 2 Duo. Sure the FSB will be "enhanced" to 800MHz with Santa Rosa. But that's hardly worth a sneeze compared to the 667GHz FSB it already has.
So I think you can forget about large multi-tasking on any mobile for the foreseeable future. Once my workflow shifted from linear to multi-threaded multi-tasking a little less than a year ago, I realized that dual core processors are really not much better than what we had for processing in 1985 - in this new paradigm of how to work a lot of stuff simultaneously.
When I ordered my Quad G5 in February, I was almost in a cold sweat panic. The sudden lack of power not coming out of my Dual 2.5 GHz G5 was frightening as soon as I had made that workflow shift. Scared me to death. I was visibly alarmed.
It was like a combination epiphany and natural disaster - fear and panic at the same time.

Apple sells music only to sell iPods. People are locked into their iPods because their iTunes music can't be played on any other brand of player.
And if you look at the number of iPods sold compared to the number of ITMS songs sold, it is plainly obvious this statement is pure bull.

If Iger is correct and iTV has a hard drive.. then I beleive iTV could serve as an external iTunes Library server/device. Authorized computers can access and manage it using iTunes (running as a client). iTS downloads, podcasts, imported physical CDs, etc would all be stored on iTV.
Look at your hard drive usage, Music takes up a significant amount of it. Why does it need to be kept on your local machine if iTV provides a network?
