2. i am trying to use this query to create a materialized view. My problem is this query returns in under 5mins. But when i try to create the view ( or even a regular table), it goes in a long-op ( sort ouput) whoes time itself is over 4-5 hrs.If it takes 5 min. to return the first rows, but hours to process the complete result set, this suggests that the problem is very likely caused by the function calls, since the sort of the result set must have already been performed to return the first rows and the function calls will probably be performed using the final result set. Try to perform the same without any function calls and check if you can build then a table more quickly.

How can i reduce the noise on this video?

I have used Keylight to key some chromokey footage onto a white background.
However, I still have a lot of noise on the video, by this I mean fuzzyness, instead of good rich colors - you can see for yourself if you download a sample of the file which I have linked to here:
http://www.youtube.com/watch?v=-MmBGI-JUMk
Obviously the actual file has proper dimensions unlike the YouTube example! This example also doesn't show the noise quite as well as the actual Flash file, it's a little more intense than it looks here.
How can I make the video fuller in color, to reduce the noise....?
Thanks.

The noise looks like genuine camera noise from poor lighting with ramped up sensor sensitivity. Therefore, as a start, I'd run the clip through a pre-comp and use the Remove Grain effect or tools like RevisionFX' DE:Noise, Red Giant's Key Correct Pro and so on. If it's DV/ HDV or similar, some de-blocking by ways of similar tools is also recommended. This should already improve matters notably. Then, as Sébastien said, study the super tight junk matte tutorial and apply the technique to your footage. The less pixels to key, the more efficiently the keyer can expand its range on the remaining ones. If you then still experience jaggy/ noisy edges a second application of the aforementioend plug-ins might do the trick. Other options include tools like Twixtor, SmoothKit, RSMB, RE:Fill etc. to mend holes and smear gaps. also, since the person is wearing dar clothes, the old trick of using a dark Inner Glow might also be applicable.

How can I reduce the brightness of my screen?

I installed WIndows 7 on my MAC and after installing the boot camp drivers, the screen went really bright.
I reduced the brightness to the lowest setting on my keyboard, but it is still bright.
The problem is not so much on the graphics, its more on the brightness of the white background & black text.

Start menu > control panel > appearance & personalization > display > calibrate color
I would adjust the keyboard setting back to midway before calibrating, this way you have some flexibility to use that again.

How can I reduce the size of a pdf file for emailing?

I want to send a pdf file which is 8 mb, it has bounced in an email because it is too big, how can I reduce the size of the pdf file for emailing?

Sometimes a simple "Save As" will reduce the file size slightly, but probably not enough to pass the <8 mb threshold of your recipient, as you need.
You've probably seen it, try the next option in the Save As menu, "Reduced Size PDF," and make it compatible with the latest version possible, again considering the recipient. This suggestion assumes Acrobat X. You don't say which version you're using, but this tool was available at least going back to Version 8, but in a different place, you'll have to hunt.
If all that doesn't work, you could remove some images from the source document, which also will reduce the overall size.
Best luck.

How can I reduce the size of these files?
Can i not use this files and see the tabscripts or others object htmlb?
thanks

Hi Benito,
these files contain all "stuff" that the BSP Extensions need to work. If you decide to code your own HTML content you don't need them.
The other thing to consider is that these files should really be cached b your browser so this overhead only happens once.
Cheers

How can I reduce the size of IPhoto ?

I have tested IPhoto with a few hundred pictures.
I do not find this software very user-friendly, in particular because I can no longer locate the files of these pictures. I kept fortunately a copy of my complete set of my photo collection.
I removed all pictures from IPhoto, but the application shows a size of 600 Mb.
How can I reduce the size of IPhoto and recover this storage space?

patrick
in particular because I can no longer locate the files of these pictures.
There are three ways (at least) to get files from the iPhoto Window.
1. Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. Show File: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
Rolls in the iPhoto Window (View -> Film Rolls) correspond exactly with the Roll Folders in the Originals Folder in the iPhoto Library Folder. You can move photos between Rolls, you can rename rolls, edit them, create them, as long as you do it via the iPhoto Window. Check out the Info Pane (wee 'i', lower left) the name and date fields are editable. Edit a Roll Name using the Info Pane, the Roll Folder in iPhoto Library Folder/Originals will also have the new name.
You might also like to explore the iPhoto tutorials at http://www.apple.com/ilife/tutorials/iphoto/index.html
Use the Get Info window to remove unwanted language resources.

How can I reduce the size of the jvm?

I would like to decrease the size of a jvm; I've found a program that makes it, but you don't know how does it works (and you have to pay for it), I'm talking about VM Optimizer 2.0, from Invirtus.
Can anyone tell me how can I reduce the size of the jvm?
Thanks a lot.

I assume you mean the size of a JVM instance in memory and not the size of the JRE which is on the disk.
I don't believe that there is any way at present for your Java code to change the amount of memory available to the JVM. This shouldn't matter too much, though. Firstly, you can control the size of the JVM from the command prompt with the -Xms and -Xmx options. Secondly, any remotely reasonable operating system is going to wait until the JVM has requested memory before allocating all of it. If you start a JVM with a 2Gb heap, it does not occupy 2Gb of physical memory straight away.
Finally, I did a Google on InVirtus VM Optimizer and must request some information. What does that software have to do with Java? It's designed to reduce the size of a virtual computer as created by a prorgam such as VMWare. It has nothing to do with the Java virtual machine.

How can I reduce the size of some apps like Facebook, Twitter,whatsup..etc..as they eat a lot of space on my iPhone 4s ?

How can I reduce the size of some of the key apps likeTwitt Facebook, whatsup etc..I have a iphone 4s 7 GB?

Its frustrating. I also have this problem with Dropbox, a great service but they dont have a 'delete cache' button. Dropbox told me to log out and back in again but nothing. If i delete the Dropbox app (And Facebook app and Twitter) and then re-install its back to its original size
If you go into settings/general/usage and see all the apps, press the app for Twitter (Or Facebook) and you'll see how much extra the app is keeping under 'Documents & Data'
Delete those apps and re-install and the documents and data will be 0 and the app back to normal.
Its frustrating as some of these apps can get huge, after viewing a video my facebook app went up to 450 meg ! Same for twitter. I tend to use 'Twiterrific' as the app size doesnt get silly unlike the official Twitter app

Keep in mind that Logic also has a limit of 8550 quarter notes. So changing the time signature to 4/8 can get longer recording times. So make sure you change this setting along with the song end. See page 93 in the reference manual.

I have a Mac Pro OS 10.7.5 and have a DVD+R disc with files on it, but it ejects the disk after about 10 seconds--what to do? How can I get the data off this disc? I can see it has been already burned, so files are on there?

Try cleaning the lens and see if that will restore functionality to the DVD drive. Use a DVD lens cleaning disk, if you have a can of compressed air, shoot some into the slot or wrap a fine microfiber cloth (eyeglasses cleaning cloth) around a business card and insert it gently inside the slot.
If no success, make an appointment at an Apple store genius bar and get a free diagnosis from them.

What format are they? Tiif? Jpeg? You can compress them with a lot of apps - including Preivew and just about any graphics editor out there. I'm not sure that 45mb would crash iPhoto thogh, are yo sure that's the cause? I know that some folks have mentioned pixel dimensions causing issues, as can color profiles.

Why is my word and pdf files so large? How can I reduce the size?

My document contains mostly photos from a database via a path to the actual jpeg photos on disk.
There are 39 jpeg photos + a small amount of text with each photo.
The 39 jpeg photos on the disk add up to be 5.79 mb.
If I export the crystal reports document as [Microsoft Word (97-2003) Non Editable] the, the file size is 36.8 mb.
If I export the same data as a [Microsoft Word (97-2003) Editable] the file size is only 3.1 mb.
That is a difference of 33.7 mb! Why?
Also, when I export the same data to a PDF file it is much larger than I think it should be; 12.7 mb.
Why is my word and PDF files so large?
How can I reduce the size of the word and PDF files? (without reducing the photo quality).
Are there any tools to post process the Word or PDF files to reduce the file size?

You can't, extra size is to hold the details

if you try to install an app that depends on adobe air, you should be prompted to download and install adobe air (unless it's already installed).
you can download and install directly so you're not prompted by that app, Adobe - Adobe AIR

How can I reduce the bit rate of songs in my Music Library to enable me to

At the moment i can only fit about 1300 songs on my iphone and also have used up half the space on my 120gb Classic with 7000 songs which is a lot less than what i was told would fit on. so............
How can I reduce the bit rate of songs in my Music Library to enable me to fit more songs onto my iPhone or iPod Classic.. and what is the minimum rate that i should stick to in order to retain good sound quality.

For existing tracks, see:
http://support.apple.com/kb/HT1550
For CDs you import in the future, change the Import settings in the iTunes -> General preferences.
As to what will be a good bit rate, that's going to be up to you and what quality you find acceptable, but many people find that 128 kbps AAC is the optimum balance between small file size and quality.
