What does 7.3 good for

I don't know if I should upgraded or not. What's the difference?

Don't yet. Wait for the bugs to be worked out. I always give iTunes updates a good month or two before actually upgrading. Though you could check the discussion boards here and see what people are having troubles with if you'd like to form your own opinion.

What is Hashtable.clone() good for?

I want to make a copy of a Hashtable. I read the javadoc of Hashtable.clone() and it says:
"Creates a shallow copy of this hashtable. All the structure of the hashtable itself is copied, but the keys and values are not cloned. This is a relatively expensive operation. "
What does this mean? I want my copy to be de-coupled from the original, i.e. when i change anything in my copy, the original should be untouched. But the sentence "the keys and values are not cloned" seems to result in a coupled copy. So I have to copy all keys/values into a new Hashtable object myself. Leading to the question: what is Hashtable.clone() good for?

I prefer this to ad hoc speed testing classes.
import java.util.*;
public class SpeedTester{
    public static final long OUTER_ITERATIONS = 100;
    public static final long INNER_ITERATIONS = 10;

        Data[] data = {new StringData()};
        Test[] tests = {new TreeMapTest(), new HashMapTest()};
        long[] times = new long[tests.length];
        for (int j = 0; j < OUTER_ITERATIONS; j++)
            for (int k = 0; k < data.length; k++)
                data[k].create();
            for (int k = 0; k < tests.length; k++)
                System.gc();
                times[k] += test(tests[k]);
        for (int j = 0; j < tests.length; j++)
            System.out.println(tests[j].getClass().getName() + ": " + times[j] + " - "

                + " millis per test");

I've been raised the SR for this case ,and also install the Patch 6047085, the issue still happened. The ORACLE ask me: what kind of object this is, what is the owner etc? How is this object called? Can someone can tell me what does the WF_EVENT_OJMSTEXT_QH use for? or any article to introduce it?
my environment : ebs 11.5.9
database : oracle 9.2.0.8 64bit
platform: linux redhat 4.0

Hi Srini:
Thank you for your reply.
Not sure why Support is asking you about this object - they should be the one providing you the answers ;-)-- I feel confused too. This issue last for one month and still have no idea for this case.
Pl see if MOS Doc 1073171.1 (ORA-7445 [kdkbin()+223] on Linux x86-64 platforms on 9i release) is relevant in your case.--- I've been apply the patch, but no help.
Regards

What does symbol ! stand for in the following code?

What does symbol *!* stand for in the following code? What does SYSTEM mean?

It is just part of the XML specification; to do a "doctype", you must have an open angle bracket followed by an exclamation point. See [doctype decl | http://www.w3.org/TR/REC-xml/#NT-doctypedecl] for more information.

ACR 4.4, ACR 3.3...What does the "ACR" stand for ?

In the Camera Calibration tab in Camera Raw or Lightroom, we can choose the profile from the menu.
There are so many profiles in the menu, ACR 4.4, ACR 3.3...What does the "ACR" stand for ?

ACR x.x designates an older style of profile where Adobe named their profiles for the version of Adobe Camera RAW that first supported the camera--basically the vintage of the profile, so if Adobe updated the profile then you'd be able to pick whether you wanted the old one or the new one.

What does Apple mean by "For best battery performance, leave your device connected to a power source until the restore is complete."

I just recently returned an IPad air and exchanged it for another. I first set up this new one as a new IPad but then deleted all content and settings right away (since I wasn't getting the progress I had made in apps and games) in order to restore it from my previous IPad Air. I then checked after on how to backup via icloud and saw this line under the subtitle of how to restore from a backup, "For best battery performance, leave your device connected to a power source until the restore is complete." What does Apple mean by "for best battery performance"? Im just a bit worried of issues.
p.s. And yes I did have it connected to the power. And the ios is the default ios for new IPad Airs.

Welcome to the Apple Community.
It only means you should restore whilst it is connected to a power supply, so that your battery doesn't go flat during the process.

HT4623 what does the mm stand for on my model of ipad mini?

what does the mm stand for on my model of my ipad mini that is also cellulat?

Copied from another discussion, from Phil0124
The MM or Millenium Media according to what I can find, refers to the CDMA variation of the Cellular iPad for Verizon Networks.
The non MM version is for GSM carriers like AT&T.

HT201471 What does the (MM) stand for ie wi-fi+cellular(MM)?

What does the (MM) stand for ie:wi-fi+cellular (MM)?

I don't know what the "MM" stands for specifically, but those are the CDMA models, A1455 for the mini and A1460 for the 4th-gen iPad Retina.

What does the "1" stand for on the Aperture Icon?

A 3.4 What does the "1" stand for on the Aperture Icon?

As far as I see, the red number shows that the recipient has accepted the stream. If you delet the stream the red number is gone.
I am not sure -this may be a coincidence: Yesterday I saw the red number "1" appear everytime I received a notification when a comment was added to one of the images I posted. When I read the comment, the number went away. The number is gone now, but I still have the stream.

What does the "s" stand for in iPhone4s

What does the "s" stand for in iPhone4s??

Yes, that is correct. There is no right answer 100%. I don't really know how to explain it. But you have to see where I am coming from. I guess you can think about it like this. S is a word. The word was defined as speed 2 years ago. Now it is being used again. Since S was already defined it does not need to be defined again. It just makes sense that apple would be consistent in their product names.
But that isn't what they said. They said "that's the probmlem i'm having with people saying its siri.." In other words, that's why I am not so sure siri is the correct answer. They are just curious, that's all. If someone said, "The iPhone is to die for" would you think they would actually die for an iPhone? Like I said, just relax. You don't need to go attack people by saying that they need mental help when they are just curious about something.
However, you are entitled to your opinion. I have presented my case and you seem to be getting pretty upset over my comments so I think this whole thing should be let go. There are plenty of posts here for the OP to make a decision for themselves and if he/she needs more clarification he/she will ask.

What does Abbreviation SWC stand for?

What does Abbreviation SWC stand for? I know that swf stands for ShockWaveFlash. The only declaration I found was ShockWaveControl. Is that right. Or does anybody knows that.

Hehe, you may be right. But for me (as a teacher) this is the questions we get all the time :-) Let's settle with "small web" AND "Shockwave".
If you are the type that tend to trust Wikipedia, SWF is now "Small Web Format" (http://en.wikipedia.org/wiki/Swf) to clarify it's meaning.
For SWC, references like http://www.filesuffix.com/extension/swc.html and http://en.wikipedia.org/wiki/Adobe_SWC_file refers to a "Shockwave Flash Component"
One can say that a swc is practical during development, but have nothing to do with the small-web thing. So it looks like you were right in the first place, but with a underlying risc that it will change if the brand police somes around the swc-house :-)
