If your Mac is slower than a PC for any reason on the same application it is because the software hasn't been optimized for the Mac. Write the software developer before you complain about the Mac speed. Get them to develop for Altivec. It makes a world of difference.
No chance.
Most applications that can take advantage of Altivec already do, there's a lot of processes that can't benefit from Altivec at all and that's where the G4 is getting beaten senseless.
Even Altivec itself is crippled by the bus speed.
The G4 achieves 1.3Gb/s on the dual 1Ghz G4 with the 167Mhz Front Side Bus.
Remembering that there's 8 bits in a byte and memory is 64 bit the Mb/s of the FSB works out as follows :
(100 / 3) x 5 = 166.666 this is just the precise way of calculating the bus speed
64 bit / 8 = 8 bytes
8 x 166.666Mhz = 1.333 GB/s
Remembering that 1.3Gb/s is the most the system controller can transfere to either CPU, altivec is hardly getting any of the juice it needs at all with the current G4 design.
Assuming we're still talking about that dual Ghz G4, Altvec works out like this :
(128 / 8) x 1000Mhz = 15.625 Gb/s
It's only getting a measly 1.3Gb/s, hardly what it needs.
Plus both CPUs and both Altivec units have to share the same 167Mhz FSB to transfere data to and from main memory.
Even though the L2 and L3 cache have a lot to play in getting around the FSB bottleneck, that's 1.3Gb/s of bandwidth shared between cpus and SiMD units that require a total of 33.85Mb/s.
If you're working on data that's less than 256K it fits in the L2 cache and there's no bottleneck, anything bigger than that and it's either got to fit in the L3 which is half the required bandwidth or it's coming from main system memory with that tiny 1.3Mb/s of bandwidth.

Its actually a quite clever design and means that the iProducts 30pin connector can be relevant for many more years to come.
can you please explain to me (or provide a link where it's explained) the benefits of using a 30 pin connector in comparison to a usb port? is it maybe so that apple can sell more adaptors? (i'm not sarcastic on this one, i'd really like to know)

Hello,
I do some download in my app where some of the data are images. In my app I save this data and create uiimages object where needed. Everything works fine so far. My problem is:
I have a custom tableViewCell class and in this class I have a UIImageView defined. No matter which size I set to this Uiimageview, the image put into it gets the height of the tablecell. I have tried to change the viewMode for the cell uiimageview content but without any luck so far. What can I do to actually get the images to be displayed with the size of the uiimageview it is added into...?
The images is created like this:
NSFileManager *fileManager = [[NSFileManager alloc]init];
UIImage *imgToUse = [[UIImage alloc] initWithData:[fileManager contentsAtPath:[dict objectForKey:@"data_path"]]];
[fileManager release];
After this the images is saved into a dictionary and in the table delegate method - (UITableViewCell *)tableView:(UITableView *)t cellForRowAtIndexPath:(NSIndexPath *)indexPath {
the image is added to the imageView, like this:
cell.imageView.image = [[self.imageDict objectForKey:@"some key here"];
Any Ideas? I do not understand why the cell height controls the image height? What am I doing wrong?
Thanks in advance!

Sorry I don't have that video card in mine so I can't report replication of the problem. Sorry to hear that. Bummer.
Yeah, I am pretty sure the main culprit is the GT 7800 card. I am thinking in get rid of it or pressure Apple to upgrade for a better card.
Anyway, that's life in the computer world.:rolleyes:

It's nice to see that the banner from the Apple website is being replicated at the MW venue (assuming it isn't a fake), but it shouldn't been seen as an indication that 2007 is going to bring amazing products. Remember that apple has a track record of over-hyping itself.

Question for folks who have gone (or purchased ticket voucher). From the looks of it, you buy a voucher, which you then redeem online for a ticket, correct? Can you buy the voucher now, but fill in the attendee ticket details at a later time? I'm going to buy, but there's the off chance I won't be able to attend, so I'd like to give the ticket to someone else.
Yes. I got mine this morning, and buying a ticket is separate from activating it. After you buy, you'll get a link to activate it, and you could forward that link to someone else if you can't go. Once one person activates it, however, it becomes non-transferable.

I hope it fixes the USB connection to Canon cameras. They broke it with 10.4.7. I'm still booting from my portable backup drive when shooting tethered (looks really pro on location).
I dread the going-backwards-sytem-reinstall BS tho, so that's what I have been doing.
My EOS 400D works fine (in tethered mode as well as just transfering from the memory card)?

Nah... based on military policy we wouldn't even hear of them...
...you know... Switch But Don't Tell!

I agree with the crop. I'm not sure why I didn't think of it or do it before. I remember feeling the same way but then ignoring myself. :)
This is a "quick and dirty" crop using the crop tools in flickr. I would like more room on the right for the table. This is cropped to the edge of the empty chair, so to do a bit more room I'll have to erase the part of the chair that shows. I may try that when I have more time.

That's better but give it a try even tighter. Bring the right edge up past the tray. That might make the toys jump out a little more. Same thing if you bring the bottom edge up closer to his elbow. You may have some room to bring the top and right in a little tighter to match the bottom and left crop.
I'm not sure if this will make a better photo but from what I see I think it is worth a try. (Gotta love the digital age!)
I found the original crop interesting at first glance but the more I looked at it the more I lost interest. It may have been the clutter of the bars and expanse of the table and chair to the right - the main focus seemed to get lost. I dunno. ;)

I don't think Pages is horrible. It's not great, but it isn't quite as bad for me as everyone else finds it. I don't use it all that much (Keynote gets used far more than Pages does).
I'm with you. I'm new to the world of Mac and I want to stay clear of Word. It's not a great app, but it's something I'm getting used to.
Same with Keynote, different approach, but I like it better than the world of PP.

He's better than the McCain would have been in most things, but on a whole he gives in to the Republicans way too much. He passed their healthcare plan instead of one that would actually work, kept Guantanamo open, and as far as "National Security" goes he's about the same as Bush. So basically, he was the best of the two choices, but still not very good.
"yes he can" lie.
Obama is a joke. False hope and the naive people didn't think so.
Trump's hair is seriously the mojo. Love it.

Capacitive home button sounds believable as apple has gone away with buttons on the MacBooks trackpad. Apple likes touch, not clicking. Lol
Would be useless. Can you imagine gaming with this? The only way it would work would be if it required a two finger swipe or other gesture. Or swipe from the home button up to the screen. It it activated just by touch, the iPod would now be useless for gaming.

I can see why they'd do it with a "new" program, but SE16 was my audio editing prog of choice even having to open OS9 to use it. Finally, soundstudio came around and went multi track, and although I like it, the bit view in SE16 was priceless for what I do, and that thing saved and opened files in a snap.
Even though it's new, I still had hoped that UBs would be the norm for new stuff for longer, especially from someone like Adobe. I got my G5 in mid 04 and had hoped to have it for 8 years. Looks like it'll be more like the 4 years I had ye olde G3 for. Maybe I can squeeze more out of it, but we'll see.
Whatever,

i don't know why wally world and target are complaining, this will not hurt DVD sales. like what was said. there are allot of people that cant afford new Mac's to play there movies (my problem). or live outside of the city and don't have a high speed connection (cause they are to far out) or just cant afford satellite internet. i like to have the original copy (in dvd format) i know allot of other people that also like to have a dvd of the movie.
boy are they stupid (wall-marts and target) in not seeing this.
