Someone Please Explain This to me-Quad G5 running slower that Christmas
I just got my Quad Powermac G5 fully loaded w/ 8 Gigs; 2 500 Gig Hd's and this thing is running slower than my 15 inch powerbook with 2 gigs. I am running Motion 1 and I am simply taking a picture and applying an effect (nothing crazy just simple blurs and such) and it will not play in real time? it seems to be just as slow at rendering effects as my powerbook? it took 3 mins. to render 15 seconds? Could someone please explain this phenomenom? I am a little baffled and ****** off.
Quad Powermac G5 Mac OS X (10.4.3)
Mac OS X is heavily cache and swap dependant, its like the OS was designed to run with flash RAM instead of hard drives or something.
The speed of Mac OS X will improve greatly upon the I/O speed of your boot drive.
Since you got the stock 250 GB, most likely without a large 16Mb cache, Mac OS X will crawl slower and slower as the boot drive fills up.
I've noticed with my brand new 20" iMac G5 that I'm getting beachballs, there is nothing hardly on the drive and it's not even hooked ot the internet and it's slow, a pig 250 GB 7,200 RPM drive.
My main machine in my signature is lighting quick, windows snap open, program launch fast as heck and boot time is under 30 seconds. Actually it's a combination of things, fast video card, plenty of RAM and fast drive I/O speed that make a Mac snappy with the feature and eye candy rich Mac OS X.
The Quad has four processors, so CPU intensive multi-threaded applications will perform long jobs in short order. As well as running many applications at once.
What will help make your Quad snappy is to replace your boot drive with a 74 GB 10,000 RPM Western Digital Raptor and keep it slim, keep your files on a second drive, leave your iTunes and User "home" folders alone on the Raptor just near empty.
I've written it up here in a text doc

Music in the event browser but it is not working in my video, can someone please explain this to me?
Hi I've been working on a Mac fir less than a week now and I'm using Final Cut Pro X.
For some odd reason my music isnt picking up in the timeline correctly, but is showing the audio file in the Event Library.
There are to Macs where I work and they are copies of each other; so what happens on the one happens on the other. With this in mind I duplicated the project and copied it onto the other Mac.
The odd thing about it is that 3 out of the 5 audio clips just dont pick up in the timeline that it is in the event library but you can manually find them there.
I would just like to know as how you can fix this, as I am working on a small project at the moment and if the project was bigger I would be in searious trouble.Please give the exact specifiations of the audio you're talking about? Is it compressed audio? It probably needs to be converted.

ITune 7 and video ipod - can someone please explain this?
Is there any chance that iTunes could somehow be forced to allow uploads of movies and TV shows to the iPod with 1.2 update?
My real question is, someone above says 1.2 is only for other ipods, not 5g video. Can someone confirm or deny this?
The current situation here is:
- iTunes 7 wants to update the iPod software, but when I agree to this, it ejects the ipod and the progress gauge keeps showing indefinitely.
- If I stop the iposervice, the update fails (of course!) with the 1417 error.
Multiple times:
+ I have reinstalled iTunes7 twice following all the instructions about deleting temp and iptune directories, etc.
+ I have tried disconnecting and resetting during the original update dialog.
+ I have disabled all services and tried all this again
The two problems remain:
iPod not recognized by iTunes 7 (but works perfectly with iTunes 6 so it isn't a hardware or Windows problem).
Forcing recognition by stopping and starting the ipodservice works, but the upgrade to 1.2 fails.
I could live with all the above by going back to v6, but
V6 refuses to upload purchased video content to the iPod without the updated software.
iPod 5g video Windows XP Pro normally a reasonable personinstead of stopping the ipodservice, try eboncairn's
does that get you past the 1417?
I did that. Notice that you don't address my question. I found a way to get things working and I'll post it in a second under a new title because I'm guessing a lot of desperate people will want to try it. First here's the answer I was looking for:
When IT "suggests" yopu upgrade the 5g to 1.2, the initial gauge comes up for about 40 seconds. Then a dialog comes up and after you deal with that about 1 minute 30 secs will go by.
Then, the Apple logo will appear on the pod and a guage will show the update loading for about 1 minute.
Finally there's a reboot of about 20 seconds at which time I came in my^H^H I saw the iPod in the iRuines 7 window.
I will post all the $**** I had to do to get this working under the title, "IT7 1.2 5g update - worked for me"

Reporting Level - Can someone please explain this attribute?
All - I am a relative newbie to Siebel on Demand but creating reports with other tools for years. I recently came across some reports that I have inherited that are constantly giving us trouble. They are basic reports that look at the count of calls, meetings, etc. for a given user. What we are finding is that we have used this reporting level attribute to filter but depending on the level of manager logging in it is causing problems. Some people can't see the data and some get a massive amount of duplicated data.
When it is all said and done we are looking for a simple manager-to-rep list of the counts of these activities. After looking at the reporitng level value it would look like an indicator of relative position from the lowest level in the reports-to heirarchy. We will generally filter for a level = 0 (or maybe 1) in most reports but what I want is a way to control that based on the user. My requirement is to have the level they can see and the detail at one level lower but I dont' fully understand how that gets created or how I can use system variables to find the user's level to control it.
Anyone that has any background info on this or how I can control a basic anaylytic report in a more maintainable fashion to show my stuff and subtotals at one level lower that would be greatly appreciated.Not sure if I can help with the specific report, but I will try to shed some more light on Reporting Level.
In any report where the Owned By User dimension is exposed, you can find the Reporting Level field. Each user is part of a reporting hierarchy, derived from the "Reports To" value in their user profile.
The best way to see this is to create a simple report with the User Email, Reporting Level, and Manager Email. This will show you the manager at each level. You can use this to expose and filter on the full management hierarchy.
Level 0 = the user. All users have a value of themselves as Manager at Level 0.
Level 1 = Reports To - who the user directly reports to.
Level 2+ = Up the chain...
You may want to take a look at some of the pre-built reports to see how this can be used to achieve Team based reports, such as "Team Pipeline Analysis", "Team Sales Effectiveness Analysis", and "Team Activity Analysis". You can open any of the pre-buiilt reports to use as starting points as well. -
hi,
can any one please explain this behavior.
This is what i did.
create table temp as select * from dba_extents;
insert into temp select * from dba_extents;
insert into temp select * from dba_extents;
insert into temp select * from dba_extents;
insert into temp select * from temp;
insert into temp select * from temp;
insert into temp select * from temp;
commit;
temp table now has arround 8449024 rows
collected all the statistics now
the following are the various waits for the session

db file parallel read 8 0 0 .04
direct path read 22352 0 2883 .13

now i issued select statement
select count(distinct block_id) from temp;

db file parallel read 8 0 0 .04

the select statement was actually making the full table scan of the table and the explain plan showed as below

can any one please explain this behavior.
1. oracle tells us that when the full table scans are performed db file scattered event appears but here clearly db file parallel read was occuring.
2. as the table was going through the full table scan as oracle 11gr2 default behavior will not cache the blocks that are part of the table going through the full table scan is this the reason why the db file parallel read wait event was occuring.
3. clearly in the explain plan it used a view called VW_DAG_0 which is inexistant on the database is this a bug or this is the behavior of oracle optimizer to create a view.
4. before collecting any statistics on the table when the same sql statement to count is executed a lot of db file parallel read waits appeared, can any one please explain this behavior.
5. while doing the full table scans if the oracle shows the waits as db file parallel read (occurs when the recovery or parallel processes are used), but is this behavior changed.
finally,
6. can any one please explain the difference between the db file parallel read and db file scattered read.

In Pages 09 we can do Mail Merge and Import Styles from a document. Can someone please explain how we can do this with the new version of Pages 5.1. Even Apple solutions are only valid for Pages Version 09. What a DOWN GRADE! Thank god Pages 09 is still there.
…and the other 98 missing features.
Just use Pages '09, which should be in your Applications/iWork folder.
Rate/review Pages 5 in the App Store.

I recently migrated from a MBP with OS 10.6 to a MCB with OS 10.8. Some glitches are popping up. Here's the one on my mind at the moment:
When saving or opening documents, I get a warning such as: "Word cannot save this document due to a naming or permissions error on the destination volume." Can someone please explain?Since this is isolated to a single file, try exporting it to Interchange Format (.inx), then open and save the resulting file as a new InDesign file.
Since the problem occurs during export, that may not be possible. Another option to try would be to copy all elements, page by page, and "paste in place" into a new document the same size. If you used layers, be sure to enable "paste remembers layers" in the layers panel menu.
This kind of problem is often indicative of an underlying font issue. You said there are only three fonts, and you should verify that in Type > Find Font... Try replacing, at least temporarily the fonts in use with something else that you know to be reliable from other documents. You might want to do this before the other steps.

what does it mean when you're about to install itunes and it says This update requires OS X version 10.6.8 or later.??? i don't understand... Can someone please explain to me what that means...??? And how to fix it.
1. It means exactly what it says. Apple dropped support for earlier Mac OS X versions in iTunes 10.7.
2. Update the computer to 10.6.8. If it's running a Mac OS X version prior to 10.6, this requires buying a Mac OS X 10.6 DVD from the online Apple Store, which requires an Intel Mac with at least 1GB of RAM.

Could someone please explain to me how to set-up my Apple ID so that both my password AND security questions have to be answered before access is granted? Is this possible? I am not very computer smart, so could you explain step-by-step!Very Appreciated!
The security questions will only be asked on the first purchase on a computer or device (though people have occasionally posted that they've asked for them when it isn't the first time) - I'm not aware of any way to change that. You can force the password to be required on your iPad via Settings > General > Restrictions > Require Password set to 'Immediately' (the default is a 15 minute period during which it doesn't need re-entering)

RajivDear Rajiv,
Because you make a join with > sign
Oracle decide
First - search all EMPLOYEES that match you filter condition first_name like 'K%' and ordering then by departament id
Then - Oracle sort all departament on dept table by id
With both sets Sorted, Oracle simply go to one set and check another set, and join then.

HT2493 Could someone please explain colour tags?
I do not understand the use of colour tags on my Macbook air. Could someone please explain?
The colours are incidental. They are NOT labels any more. You will be frustrated if you try to use Tags to visually find your files.
The advantages of tags are this: you can add as many tags to a file as you like. They provide additional metadata so that you can query your file system. In a typical hierarchical file sytem (folders, subfolder), a file can only be in one place (unless you use aliases).
If I have "Cheeses > France > Soft" as my folders, I can put all the French soft cheese into one folder. But all the English soft cheese are in England > Soft. So what if I want to list ALL the soft cheeses, not just the ones from France? By tagging all the files with "Soft", I can then click on the Tag Smart Folder and list the soft cheeses in both countries' folders all at once.
If used creatively, you could have ALL the files in your Documents folder in one big heap, and then only view subsets of them according to their Tags. Tags represents a complete alternative to using folders to sort your files.
In a sense, a subfolder is simply a Tag in a tree-like structure.
So, instead of trying to visually find some files in a list using coloured labels, you can now query the file system by creating Smart Folders that give you a list of files that match your query: files with Tag X, in folder Y, of type PDF, bigger than 2 MB, containing the word "trumpet".
Visually scouring a folder for files is not as efficient as directly querying the system, even if it is engrained and familiar. -

drop from 28.57 to 26.84
Nothing has changed no powercuts no resets same equipment so why?They could well be rebalancing the gateways to share throughput more equally. There have been lots of reports of people getting massive slowdowns during peak hours.

hi could someone please explain why the iPhone 5 is $600 dollars more expensive to buy in australia than in the US

The phones on the us site appear to me to be the unlocked phones. the contract phones are even cheaper . Australian taxes account for a 10% price diference but really all the Apple products sold in Australia are at least 30% more expensive than in the US and other markets . Why are the local (Aus) apple retailers continuing to price gouge . The ACCC must act to stop this blatant con job..
There are no options currently on the USA Apple online store site to pre-order unlocked iPhone 5's. The iPhone 5's currently available for pre-order are only availble by selecting a carrier and agreeing to a 2year contract. The prices listed are all contract-subsidized prices. -
