Question about NAT Inside Source, Inside Destination, and Outside Source

I read the Cisco command references about "ip nat inside source", "inside destination", and "outside source", but couldn't have a clear understanding of how to associate the commands with "ip nat inside" and ip nat outside" configured for interfaces.
Does "ip nat inside source ..." translation only happen on the interface configured as "ip nat inside"?
Since NAT is a bidirectional action, what's the difference between "ip nat inside cource ..." and "ip nat inside destination ..."?
I've never used "ip nat outside source ...". In what cases would it be needed?
On an interface where there are NAT translation and also other actions such as policy map or IP Sec crypto map, would NAT happen before or after other actions?
Thanks for help with any questions.

Difference in Inside-out and Outside-In development approaches

Hi,
Can you please tell me difference between Inside-out and Outside-In development approaches. I heard it with respect to adapters and proxies.

Hi Rupesh...
<b>Nice question as a Project Management point of view..</b>
We can go for Interface development in 2 ways..:
1. Create Interface objects in XI and replicate that thing in both sides for further development..
Adv :: You are not dependent on others for XI development....Like in case of Proxies.
Disadvantage : Skill in proxy required..
2. Create RFC/IDoc in end systems and import those in XI for development..
Advantage : People are usually familiar/comfortable with adapter oriented approach rather then adapter less..
Disadvantage : you can't start your work before the end systems have completed their task..Once they have completed then only you can import the RFC/IDoc and proceed..
About deciding the approach : It depends upon teams strength/situation ...Like in one of the project i have worked Project needs to be done by a Consortium of 3 teams from different companies..One for handling legacy one for R3 one for XI..
So we went for Approach 1 as we don't want our work to be dependent on others..
Hope i am clear..
Regards,

Inside-out and Outside-in development

What is Inside-out and Outside-in development in XI related to Adapters and Proxies?

Hey
Outside-In: You can develop new, platform-independent message interfaces by using the Integration Builder. Message interfaces are based on the WSDL standard Web Services Description Language), an XML schema for describing network services. Using this description, you can generate platform-specific proxies in Java or ABAP that you can then use to implement the actual message exchange.refers to Proxy development
· Inside-Out: You can connect interfaces from SAP and non-SAP systems to SAP Exchange Infrastructure by using adapters. The Integration Builder can import interface descriptions in XML format for BAPI, RFC, and IDoc interfaces from SAP systems Release 4.0 or higher.Refers to adapters usage

If you have a rescue email address set up on your account then you can try going to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you might see an option to send security question reset info to your rescue email address.
If you don't have a rescue email address set up then go to Express Lane and select 'iTunes' from the list of 'products' in the middle of the screen.
Then select 'iTunes Store', and on the next screen select 'Account Management'
Next choose 'iTunes Store Account Questions' or 'iTunes Store account security' (it appears to vary by country) and fill in that you'd like your security questions/answers reset.
You should get an email reply within about 24 hours (and check your Spam folder as well as your Inbox)

Question about expressions inside AE

I don't even know what to search for on google to find the answer. So after an hour trial and error inside AE and failure in google search, I'm coming here to seek help.
I have a plugin (RedGiant Sound Keys) that is giving values as keyframes for every frame. And the values go like: 0, 4, 7, 3, 5, 0, 0, 5, 6 ....
In other words, they fluctuate between zero and, say, 10.
I want another layer to get this value, but add it to itself every frame. I used to do QBasic programming and it was very simple there. Just something like x = x + (value from the Sound Key plugin)
But I don't know how to do this in AE.
Right now I have this:
x = (thisComp.layer("sound").effect("Sound Keys")("Output 1") * 0.5);
x;
What I really want is:
x = x + (thisComp.layer("sound").effect("Sound Keys")("Output 1") * 0.5);
x;
But it doesn't work.
Can someone help me please?

AE does not store persistent temporal variables. you have to accumulate them manually and write your own loops.
Expression Speed and Frequency Control
Soundkeys has an accumulate mode built-in, also, so rather than put up with complex expressions, simply use a duplicate instance of the effect and tweak the values.

Questions about the future directions of InfoPath and Microsoft Access

Because I have been confused about the future directions of InfoPath and Access, I wrote a short blog post, which I have pasted below. My question is, can Microsoft provide some more guidance on Access vs InfoPath? If Access is indeed the
the future direction, can you please provide some pointers to resources that can help us transition.
A Short Review of MS Access, SharePoint ,InfoPath (2013)
After the November 2012 SharePoint Conference in Las Vegas (#spc12) there were a number of blog posts and people saying that Access 2013 was great and would be replacing InfoPath.
Marc Anderson and
Ruven
Gotz have short posts summarizing #SPC12 and touch on the subject of InfoPath and Access. I also spoke with several individuals shortly after #SPC12 and they were excited about Access 2013.
Since I rely heavily on InfoPath for much of what I do, I wanted to kick the tires and see what everyone was talking about. First, a few notes about SharePoint 2013 and Office 2013.
Microsoft should rename Access: If you have tried to
bing the word Access, then you know that the search results are overwhelming, because the word "access" is used for so many other purposes.
Use the RTM version of Office 2013! I was performing my investigations by leveraging the Office 365 Beta and the Office Applications that come with it. Not much was working! After I uninstalled the Beta
version of Office 2013 and Installed the RTM version everything seemed to work.
Windows 7 and IE 9.0: The drag & drop that is being touted as
"manna from heaven" seems to work well with Firefox, Safari, Chrome, and IE 10, but it does
not work with IE 9!
Non Microsoft browsers are still second class citizens (except for the drag & drop): Microsoft has finally done away with the Active X's for datasheet view (that is brilliant!) One can now see the newly
minted datasheet view in many browsers. But I still find that one needs to be in IE to do a number of key manual opeartions. For example pasting numerous rows of data from a spreadsheet into the new sheet view works only in IE.
Access 2013
Microsoft Access is touted as a non developer tool. I know a number of people who are on the business side and love Access. These people will like the renewed energy that Microsoft has applied to Access. One should note that conceptually
this functionality existed in SharePoint 2010. Here is what I see that is new:
+The new version works better:Although I haven't tested it fully, it seems that many more features that work on the Desktop version of Access, now work in the published Web Application which is hosted by SharePoint 2013.
+The new version has fairly robust browser based forms: End users can now fill in data using forms that are rendered in the browser.
+The published version that resides in SharePoint now uses its own SQL server tables. So the engine appears to be SQL Server, not a modified version of Access built for a server. This stands to be quite robust, but I imagine
that some quirks will surface due to new model.
The limitations are:
- Access is pretty much its own application and does not integrate with SharePoint building blocks. For example, an Access table is not easy to integrate with a SharePoint workflow. Further, although Access forms now are visible
in a browser, they are not nearly as rich as InfoPath forms. InfoPath forms cannot easily integrate with the Access tables. In order to integrate SharePoint features and Access, one needs to tie SharePoint list(s) to Access as data sources.
This overcomplicates the model and one may very well run into synchronization issues.
In short, although I believe there will be some people who will be happy with newly minted Access, I do not think that Access will be able to replace InfoPath and Workflow technologies. I do agree that Microsoft does not seem to have put much energy into
InfoPath. If they leave a vacuum in this space, then others may very well take over, for instance Nintex Forms.

Although I agree with the comments made by Ruven and Marc after the conference please note that those blog posts are their own personal opinions and that they don't work for Microsoft. A lot of people have asked Microsoft to clarify the future of InfoPath
and the response up until now has been a deafening silence. In my opinion speculations about Access replacing InfoPath are premature.
I should also point out that most of your comments about Access 2013 above are actually about Access Services in SharePoint Server 2013. Access Services are NOT Access they are a shared service offering in SharePoint that convert and publish Access
databases and forms. As you point out once an Access database is published through Access services it is converted to SQL Server and no longer resides in Access. Of course I don't work for Microsoft either so these are all just my personal opinion.
Having said that I doubt you will get the confirmation/response that you are hoping for from any official Microsoft channel.

The Question about stock transfer between HU-Management and WM-Management

Hi,
There is a scenario about stock transfer between HU-Management and WM-Management storage location. I use transaction MB1B , movement type 313 , 315. After Good issue from WM-management storage location, outbound delivery will genarated, then Pack, Create/Confirm TO, at last post goods issue for the outboud delivery. But when i do movement type 315, there is a warning message "Data of preceding document was not transmitted", and from the F1 help i find this system reponse "You can maintain an indicator that makes information about preceding documents in this delivery available under delivery type in Customizing. For some characteristics of this indicator, the type of preceding document and the related document and item numbers must be transmitted to delivery creation. At least one of these parameters is missing.".
So, My questions are:
1. Generallily, Outbound delivery is created by SO, inbound delivery is created referenc PO, but how the stock transfer for 2 steps generate the outbould delivery and inbound delivery? Could you pls tell me the where i can config this in the IMG?
2. What's "Data of preceding document was not transmitted" mean ? how to fix this issue ?
Best Regards

Hi,
Sure, The inbound delivery type is set up in the IMG->Logistics General -> HU management -> Basics ->Delivery type -> Delivery type determination.
For Inbound delivery type 'HID' is maintained in this view.

Question About Sharing Apps Between My iPhone and My Wife's iPhone

Hi, I have a question about downloading apps to my iPhone.
I ordered two iPhone 3g's - one for my wife and one for me, and I've discovered that when I download an app (even free ones) on my iPhone and then later sync it to iTunes, my wife cannot put it on her phone. However if I download it on iTunes on my computer and later sync it to my phone, then my wife is able to sync it to her phone as well. It's no big deal when they are free because she can just go get it if she wants it. I haven't purchased any apps yet, but is there a way to be able to give my wife apps that I purchase on my iPhone? Or do I need to purchase all of my [pay] apps and songs on iTunes on my computer to ensure we both have access? Or do I have it all wrong completely LOL?? This rights management stuff is confusing.
Thanks in advance for your help,
Jimmy

I had my iTunes account and phone before I got my wife's hers. When I first started, I synced hers from her account on my computer brought in my libraries and authorized her phone as one of the 5 allowed. She had all purchased apps and music. Over time we each bought music or apps on our seperate accouts. Of course, we told each other about cool apps or music we bought and wanted on our phone. When I went to sync iTunes was going to delete all music and apps and sync with the library I was logged into. Didn't want that, only work around I have found is to copy new music or new apps from one library to the other. Updating on the phone is also difficult because you can't switch between accounts so updates have to be done at the computer for apps bought under different accounts. I am sure there is a better way to do this and ask for an insight anyone would have. I hope it works out.

A Question about Windows games with boot camp and system requirements

I don't plan to play many games on my Mac, but after seeing what can be done with it, I've been entertaining the idea of picking up a Windows game or 2 to play in Boot Camp (considering picking up a XP PRO with SP2 for this).
My question is about the listed systed system requirements and how they might apply to my Mac Pro. I have a dual 2.26.
As a specific example, I was looking at the game Fallout 3. The box lists a 2.4ghz processor required but I've read on this forum about people running it great with less on their Mac.
So I was wondering what I would need to consider when looking at those requirements or if games in that range do indeed run well...

Thanks Kap, you're always helpful.
That's exactly what I was wondering. How the requirement on the box applied to having an 8 core at a lower clock speed.
I was looking at XP home at amazon and newegg, but haven't been able to tell if they are 64 or 32 (unless that means just install that version from the disc).
It's nothing pressing, just something I was entertaining for now.

Question about struts inside javascript variable

Hi, actually i'm using a struts + javascript to create HTML code that i use inside a popup window...
My (working) code is:
          idoc="";
          /* var cols = parent.document.getElementById('rowA').getElementsByTagName('THEAD')[0].getElementsByTagName('TH'); */
          var idoc='<html:form styleId="InsertNewItem" action="/nw/insertnewitem.do?target='+parent.newPop.action+'">';
          idoc+='<TABLE><TBODY>';
          var hiddenForm = getParentObj('hidden_data_form');
          var cols = hiddenForm.getElementsByTagName('INPUT');
          var test;
          test="cippa";
          for(k = 0; k < cols.length; k++) {
               if(cols[k].id.substring(0,3) == "hh_")
                    idoc += "<TR><TD>";
                    idoc += cols[k].id.substring(3);
                    idoc += "</TD><TD>";
                    idoc += '<html:text property="'+cols[k].id+'" value=""/>';
                    idoc += "</TD></TR>";
          idoc+='</TBODY></TABLE>';
          idoc+='</html:form>';
          var towr = document.getElementById("subwin_body");
          towr.innerHTML = idoc;
The problem is when i try to add a <html:select> to the code, more precisely i added just before the end of the table these lines:
          idoc += "<TR><TD>Ditta:";
          idoc += "</TD><TD>";
          idoc += '<html:select property="ditta_id">';
          idoc += '<html:options collection="sel_ditta_list" labelProperty="label" property="value"/>';
          idoc += '</html:select>';
          idoc += "</TD></TR>";
... but i cannot get it to work because struts seems to make some mistake with quotes and in javascript console window i get this error:
Error: unterminated string literal
File source: http://localhost:8180/nw/jsp/insertNewItemOperatore.jsp
Row: 121, Column: 10
Source Code:
idoc += '<option value="1">1</option>
(note the missing ending single-quote)
I can't understand why because with <html:text> field the same "trick" works fine... any ideas?
Thanks in advance
Luca

can you post all of your source code for the .jsp and then try running the page and once it fails do a View Source and then paste in all the generated code so that we can look at that as well.
i'm not totally positive but i have a pretty good feeling what is going wrong. the struts optionsCollection tag will render a bunch of <option> elements but print a newline after each one, which means you probably end up with something like
var whatever = '<option ...>.........<option>
<option ...>.........<option>
<option ...>.........<option>
<option ...>.........<option>';
correct? if so, that is not valid javascript.

Question about renaming XDCAM source and targets

Using XDCAM, is it okay to rename the source folder after you've transferred it? Same with the folder your transferring to. Okay to rename it before or after you've transferred the footage?

Hi,
I copy the SxS card to an external drive into a folder with a given name like CH-1. Then I change it to CH-Howe. I've thought about it and I don't think that has any bearing on anything. And I believe transfer is the wrong word. This is an XDCAM import (possibly capture). Once it's imported, the question then becomes what if I change the name of the folder the files were imported to? That seems straightforward, too. I simply reconnect or relink the media.

Question about variables inside methods

I just want to be sure that I'm clear on something.
I have a method that is called inside a class, the local variables
get initialized with my initial values.
When the method exits, those local variables get marked with
a zero reference count and are available for GC when the garbage
collector runs.
Correct?
Thanks.
-brad w.

when the method destroy,local variable destroy too .In the stack,when stack.pop(),the reference to the object still exists , though object has been removed.according to this , memory leak will appear .SO we should do something like this.
Stack stack=new Stack(1000);
for(int a=0;a<1000;a++)
stack.push(new Integer(a));
for(int a=0;a<1000;a++)
System.out.println(stack.pop());
public Object pop(){
if(size==0)
throw new EmptyStackException();
Object object=elements[--size];
elements[size]=null; //eliminate the reference out of life
return object;
/code]
affter that ,the garbage collector can do something what he want to do

Question about drawLIne(x1,y1,x2,y2) and repaint()

i am doing this project, which i suppose to use drawLine and repaint() to generate graphs. my problem is, every time i hit a new button it will call the repaint() then my old graph is gone, only the new graph is left.
for example
i have 4 buttons. movesouth() movenorth() moveeast() movewest()
when i hit movesouth two times there should be a staight line, when i hit movewest() my old graph is gone() it only left me with 1 unit to west cuz i have repaint() inside my actionPerformed function, my question is: is there a way that i can redraw these line without calling repaint () ? cuz repaint is kinda like redraw the new stuff and forget about the old ones, however i would like to keep the old one while adding the new graph to it.
your suggestions would be great appreciated.

well of course, your Graphics-Object is of the type Graphics2D, you just need a cast so that the compiler is happy ;-)
Its the same Graphics2D object/instance as withought the cast...

Question about Hz difference between MacBook Pro and iMac?

Some will think I'm crazy for saying this, but my new MacBook is driving me nuts.
In a nutshell, I have tinnitus as a result of an accident some years ago. I can hear an intermittent high pitch sound coming from the back left of the machine. I used to hear a similar sound from old TVs back when I first got tinnitus. After some deduction I realised that it was to do (I think) with the fequency. I sold my old TV and brought a new one that was a 100Hz. My theory was somewhat confirmed when they delivered it and it was the 50Hz version and yes, the high pitch sound was very evident! Upon receipt of the 100Hz model and I immediately noticed the difference.
I'm guessing then that the MacBook has something inside emitting 50-60Hz - someone on this forum mentioned that too.
Although I want the portability, I can't stand that sound all day long, so I'm thinking of taking it back and swapping it for an iMac.
The question is, will I find the same problem? I'm not sure of the technical specifications in terms of Hz's between the two machines.
It's too noisy in the shop to tell.
Any advice appreciated.
PS - did not have this issue with my 2008 MacBook pro.
PPS - makes no difference if it's plugged in or not.

Isolating the source of the high frequency would take a technician with the instruments to deteermine what components emit sound...actually very easy to do with the proper test instruments, but essential to tell you what is causing the offending sound. Unless you know that it will be very hard to determine if the iMac will not do the same thing.
Only qualitative way to find out is go to an Apple store or reseller with a good selection of hardware, work with the different hardware and see if it bothers you. Preferably with few people around and low background noise level so the sound isn't masked.
