one interesting observation about vmstat I found out is (mostly on Solaris)
the first line of information always off chart, so I usually do a few interval to get constant result.

The following SQL will get the rows of the fact table & aggregation. But how to get the size (MB) of the partition. select * from $system.discover_partition_stat That should be doable, because in BIDS, we can see the size of a partition, but from which

How to get the size of a hard disk?
Hi,
As above, how to get the size of a hard disk by using Java.
Thanks you!
AlexI would be interested in the answer of this question, too.
In core Java there is no way to find it out in a platform independent manner because of the hardware abstraction of the VM. So my only idea is to write a native library for doing this and colling it via JNI -

2. that code is ok for Image RGB/8. But with image RGB/16, now we don't know how Photoshop stores image data, and how to get image data to show???
Please help me?

How to set image size for importing photos from a digital camera
I'm using Iphoto 6 and am a novice user of my new digital camera. The camera is set to HQ image quality. Initially when I imported photos from the camera into IPhoto, the images were very large (over 1 meg) and produced good quality 4X6 prints. Now when I import photos from the same camera still set to HQ image quality, the photos are very small (less than 100 kb) after being imported into IPhoto. I think I must have changed some kind of setting in IPhoto that affects the size of an imported image, but I can't find where that is or how to change it back so that the size is not changed when imported. Can someone please help me with this? Thanks!
IMAC G5 Mac OS X (10.3.9) my other computer is a Dell Dimension L500CX running Windows XP ProDave, thanks for clarifying Toad's response for me - I was just too ignorant to connect the dots from his responses. As you said, there were 2 versions - 1 in the original folder and 1 in data; the original folder had the photos that were 1 mb. We must have pulled from that folder previously to print photos not realizing they existed in 2 places. So when we found these thumbnail photos, we just thought they were the real thing. Where can you go to learn about the struction and hierarchy of the photos in terms of what Iphoto does to an image when you import it? Is it in Iphoto help somewhere? Thanks so much for your help with this, and you too Toad for leading me down the path.
If you're getting the size from Finder, I think Old
Toad's question makes a lot of sense. Is the file
you're looking at, somewhere in a folder called
"Data" in iPhoto Library? That 56k sounds about the
right size for a thumbnail.
If you do a search for the image name, both the
actual photo and the small thumbnail are stored with
the same image, e.g. abc.jpg

How to view image size compared to Page size
In previous versions if you clicked the bottom left onthe frame of an image where the document size is you would get a small popup of an outline of the image size compared to the current page size. I cannot figure out how to see this in the new CS4 version. I've tried everything, help!
Hello Heiko,
I don't know, if it is possible, but I would say,
it's not implemented yet. Maybe you can change the picture size and use then the pictures, that might be a workaround, if you can't change the height and width in VC.
Best Regards,

Preview Selection Tool-How to get selection size in Preview?
One of my favorite tricks in Preview (prior to Leopard) was being able to hold the alt-key to get the selection size. Leopard killed this amazing feature and now I have to open Photoshop every time I want to get the size of something. Does anyone out the have any idea how to quickly get selection size in Preview in Leopard? I thought I would just be able to make a selection, crop the image and get the size that way, but worst of all, the image size only reflects the original image size and not the newly cropped size. The latter seems like a bug and the former is annoying.
I've been on Leopard for a year and I was always able to just put the cursor on the image, draw my box and hit the crop button. In the last week, I've lost the ability to draw my box. It's like it's been disabled. I've restarted to no avail. This was a great little feature as I do not want to load every picture into iPhoto.
