Can somebody please explain the vbr-nrt scr pcr in easier way?

Hello,
Please confirm if my presentation is correct. Thank you very much in advance....
First, I have called Telstra to ask what is the upload speed of the link in our atm link. They said it is 910Kbps.
Then I checked also our router and I have executed a show command à sh controller atm0/1/0
Output:
          Interface: ATM0/1/0, Hardware: MPC ATMSAR, State: up
        IDB: 0x30AB0424 Instance: 0x30AC1288 PHY Inst: 0x00000000 us_bwidth: 910  --> I am assuming that this is Upload Speed = 910Kbps and this is automatically detected by the router interface.
Second, I have checked the EF priority value. For my 5 ip phones in this site.
Class-map: cm-voice-out (match-all)
653566 packets, 134229712 bytes
1 minute offered rate 0000 bps, drop rate 0000 bps
Match: ip dscp ef (46)
Priority: 26% (133 kbps), burst bytes 3300, b/w exceed drops: 1359 --> The QoS only take effect itself if there is a congestion. If the voice packets exceeded above 133Kbps , packets will drop.
Third, My question to myself: Why Priority 26% got the corresponding bandwidth of 133 Kbps???
             My assessment: I’m assuming that it depends on what was configured on this command line --> vbr-nrt <SCR> <PCR> = vbr-nrt 512 512   (In my understanding, This is ATM shaping).
          512Kbps X .26 = 133.12 approx. 133Kbps
My Conclusion:
      From current configuration vbr-nrt 512 512  .... I’m thinking if we can change it to this new configuration --> vbr-nrt 910 910 , Does it affect the call delay?
    So that there will be a higher bandwidth for EF packets.
         910Kbps X .26 = 236.6   approx. 237Kbps

I don't know cause Apple decided for me.
As does Microsoft anytime that they release a new update that is no longer compatible with the old PC hardware.
I would hope that Microsoft and Apple would both know what operating systems will run on the hardware that is produced for them.
I would also hope that Microsoft and Apple know better than you do as to what would work on their devices, tablets, computers, phones .... How much time and money have you put into research and development on the iPad?

Can somebody please explain how to format and then reinstall Mac lion10.7 without cd

can somebody please explain how to format and then reinstall Mac lion10.7 without cd

You will need either an Ethernet or Wifi Connection to the Internet - USB Mobile device is not supported.
If you already have Lion installed you can boot to Recovery with Command R and use the Disk Utility to erase the Macintosh HD and then reinstall the OS from the Mac OS X Utilities.
You will need the Apple Id used for purchase if the Mac did not ship with Lion installed originally.
If you want to repartition the HDD you can use the Recovery Disk Assistant to make a recovery USB drive
http://support.apple.com/kb/DL1433
http://support.apple.com/kb/HT4848
As Always - Back up the Mac before erasing unless you are confident there is absolutely nothing on the mac that you might possibly need later.
If the machine is a 2011 build or later you might be able to boot to Internet Recovery with Command Option R

Can any please explain the integration business process between PS and CS

Dear Guru's
Can any please explain the integration business process between Project systems (PS) and customer service (CS).
Business Process: We do machinery Erection or commissioning, later we do provide service warranty for one year.
How we map this Business scenario in sap.
Regards,
Bhanu

basic steps for such a process would be
1) Use PS functionality for your machinery erection or commisioning work. Once the physical work is completed then close porject
2) Use CS functionality for warranty and service - set up the work as a functional location on customer site (PM/CS functionality)
3) Use service order to manage any service calls on the object which could require billing via SD module - bill value may be zero if under warranty

Can somebody please explain how to fix this?!

After doing my first ever Phone Software update on my phone (a Nokia E52) this problem started.
In the Standby mode if I choose "Basic" it shows the entire theme as it's meant to be. But when I change it to "Active" the bottom of the theme cuts off! This NEVER happened before I did the update.
Please see the images attached and you will see what I'm talking about.
Any help would be appreciated or if this problem cannot be remedied then please say so as well. I have been to a Nokia Support Centre and had a technician check it out, his only unwaiving response was "The update makes the phone better", which doesn't do squat to solve my problem jack.

If all your datafiles of all tablespaces are AUTOEXTENSIBLE (YES), then you should get entry like
CPM_DAT 10240 5500 4740 46 %.
Now, maxspace is calculated as sum((((8192*maxextend)/1024)/1024)) from table SYS.FILEXT$. maxextend signifies the maximum number of blocks that a file_id (datafile) can extend upto. That is, as the datafile is AUTOEXTENSIBLE, it has been allocated a minimum extend initially and then it can INCREMENT BY some particular EXTENTs until it reach MAX EXTENTS. So, this maxentend denote the same. Now if your database is using 8K block size (show parameter DB_BLOCK_SIZE), then we can get the maximum size of the datafile it can grow upto by using 8192*maxextend, and converted to MB (/1024/1024).
USEDSPACE and SIZE_GB calculated sam way using SUM(BYTES) from dba_data_files, just one is in MB and another in GB.
FREESPACE in 1st query is calculated as MAXSPACE - USEDSPACE, that is, space available for the file_id(datafile) to grow until reached maxextend. That is, we can guarantee that the datafile will not throw error until this value is reached and can be used out of the operating system disk space. It doesn't signify the free space for the datafile available in DB. FREE_GB in 2nd query signifies that.
% FREE is usual.

Can somebody please explain to me what I'm doing wrong (RE: PPI)

I have a file that I have rasterized and saved as a PDF, in Illustrator. It's perfect as is, but I want to lower the PPI so the PDF can also be easily sent in an email without it being a large file. (The current file is around 7mb.)
I used the Effects > Doc Raster Effects Setting to lower the PPI, and the only thing that happened is the file size only became few kb less than the original. I tried again, this time lowering the PPI all the way to a measely 7 (can I even do that?), and the file this time managed to get larger than the original. Not by much, mind you, but it's still baffling.
I don't particularly care how I acheive the effect, but I'd like to lower the file size. Also, can someone explain to me what I am obviously not understanding about PPI? Freakin' PPI, how does THAT work?
Thanks!

Rasterizing usually increases the size of Illustrator files. A circle, for example, requires very little data to be drawn. There are a total of twelve points, each with X,Y coordinates, a fill, and a stroke. This circle is stored as a mathematically defined path and will always be drawn sharply at all sizes and print sharply at all resolutions. This is called a vector graphic.
When you rasterize it you convert it to a large grid of pixels, each with its own colour value. Even a small circle at low resolution (say, 1 inch diameter at 72 ppi or pixels per inch) requires at least 15,552 bytes of data: 72 pixels across times 72 pixels down times three bytes to store the RGB colour information for each pixel. There is also some data required to identify the type of object (a bitmap graphic) and its position on the page. THis circle will only look good if viewed at a specific size and will always print poorly. It is also much harder to edit since it is no longer seen as a circle with a fill and a stroke in Illustrator. Making the fill a different colour will be extremely difficult. Fortunately for our example, the shape is simple to recreate. This is called a raster image.
In the above example rasterizing has made the file larger, harder to edit, and print poorly. All of these are bad.
Some very elaborate and complex vector graphics may be saved with less data by being rasterized, but these are rare, and they will still be impossible to edit and still print poorly because the resolution of the graphic is fixed. The advantage of vectors is the resolution is infinite. Print on a crummy inkjet and you get the best quality output of that printer. Print on an offset press and you get the best possible output on the press. View on your monitor and you get the best possible display your monitor can produce.
I used the Effects > Doc Raster Effects Setting to lower the PPI, and the only thing that happened is the file size only became few kb less than the original.

This did nothing. Document Raster Effects Settings applies to any effect in the Effects menu that produce a raster image rather than a vector, which only applies to a few commands. Effect > Stylize > Drop Shadow, Inner Glow, Outer Glow, and Feather are some, as are all the effects below Photoshop Effects. The setting has no effects on anything that has already been rasterized.
Raster effects are effects that Illustrator cannot easily reproduce without using some bitmapped or raster data rather than drawing it entirely with vectors. Effect > Distort & Transform > Roughen, for example, applies some mathematical transformation to the selected paths, so does not need rasterization. But Effect > Stylize > Drop Shadow produces a blurry transparent shadow that looks best if it is a raster. The Photoshop Effects only work on graphics that are already rasterized, so Illustrator rasterizes them in the background first. Document Raster Effects Settings lets you globally define the resolution of all such effects in the document. Higher values produce smoother effects when enlarging or scaling, at the expense of speed and file size.
I don't particularly care how I acheive the effect, but I'd like to lower the file size.
I don’t know what effect you are trying to produce. Use the camera icon at the top of a reply to attach a screen grab of what you have drawn. If this is not exactly what you want, but you can find it somewhere else on the web, post a screen grab of that, too.
Also, can someone explain to me what I am obviously not understanding about PPI? Freakin' PPI, how does THAT work?
PPI stands for Pixels Per Inch. A pixel is the smallest part of data in a bitmapped or raster image. If you never rasterize anything in Illustrator, never use a raster effect, and never rasterize anything, then pixels per inch means nothing to your file because nothing is saved as a pixel. If you rasterize something, import a raster image, or use a raster effect, then you have introduced some feature to your file that cannot be completely defined using mathematical paths. This is instead saved as a two dimensional grid of coloured squares. Each of these squares is a pixel. The more pixels you use to define a graphic, the more detail that graphic contains and the larger the file.
By definition a pixel has no size. But Illustrator uses a physical measurement like inches, centimetres, or points to define the size of everything. This means the pixels in your file must have a size, too. Pixels are not defined by size because one does not manipulate single pixels like they are objects. One generally refers to the density of pixels in a unit of measure. So a pixel is not .0033 inches, or 1/300 of an inch, rather a raster image is defined as being 300 pixels per inch. if that same image is enlarged to 200% its pixels are enlarged, so it becomes 150 pixels per inch. If this is an Illustrator path with a raster effect, the effect is recalculated after the drawing is enlarged and is still 300 pixels per inch, but now contains four times as many pixels (twice as many across, twice and many top to bottom).

Can somebody please explain me this logic?

array = [1,2,3,4,5,6,7];
newArray = array;
trace ("array: " + array);
newArray = newArray.splice (0, 5);
trace ("array: " + array);
Output:
array: 1,2,3,4,5,6,7
array: 6,7
As you can see, I set a variable equal to another (newArray = array), then splice it. But the problem is, it is affecting the old variable too!
How can that be?
I need to use the complete original "array", but no matter how many variables I create equal to it, when I splice them, it affects all of them!
I might find a solution by turning the variable into string, then back to array or something like that. But what I would like is to understand what's going on in that code. If someone could explain me, i'd appreciate it a lot.

Thank you.
That helped me out.
I found my problem also in the Flash Documentation. I couldn't find it before because i didn't know what to look for.
Anyway, here's the link if someone wants it:
http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Liv eDocs_Parts&file=00000661.html
It teaches how to create a copy of an array using a "for", but "kglad's" method is much better.

Can somebody please explain ICloud email storage ?

I use Mac Mail (within OS X Snow Leopard) with both my @mac.com address and also my @btinternet.com address.
I had a Mobile Me account also when that was still available, although that's perhaps irrelevant. (My @mac.com account is long-established)
When ICloud became available my @mac.com email account became an 'ICloud' Account although nothing else appeared to change.
I have now been told that my ' email storage on ICloud has exceeded the free limit and I must buy more'
I don't understand that, as I had no idea that my email was being stored in ICloud.
My assumption was that all stored email was somewhere within the (several terabytes) storage on my Mac Pro.
How do I stop storing email in ICloud and simply store all received email on my Mac Pro ?
Can I continue using my @mac.com account without it being an 'ICloud' account?
I do not have an Iphone or any other mobile phone. (although I do have an IPod and IPad and a MacBook)

iCloud email is IMAP, as was MobileMe: this means that the emails are stored on the server and read from there by your Mac and other devices. The stored emails use your 5Gb free or extended (purchased) space.
You can reduce the online storage of emails by downloading some of them to your Mac. Create a new mailbox in Mail, making sure it is under 'On My Mac'. Now go to your iCloud email and select the messages you want to download. Drag them to the new mailbox and wait while they download (if there are a lot it could take some time).
This will remove them from the server and free up space: obviously they will then only be available to read on your Mac, not on any other devices.
Can I continue using my @mac.com account without it being an 'ICloud' account?
No.
Your iCloud storage is also used by 'Documents in the Cloud', iOS device backup, and 'Photo Journal' galleries if you choose to host them there. It is not used by PhotoStream, iTunes in the Cloud or iTunes Match. There is no general file storage in the manner of the late lamented iDisk.
You can increase your storage space if you need to: additional 10GB, $20 p.a., 20 GB, $40 p.a., 50GB $100 p.a.

Please explain the magic! (Question)

The ActionScript snippet below is from the BlaseDS chat sample app. Can someone please explain the magic that declares the chatMessage property of AsyncMessage.body (IMessage.body?) object? It's not in the docs anywhere so I'm guessing it is not built into AsyncMessage. And it's not defined in any of the sample app source files.
Coming from a strongly-typed development world, seeing a property that apparently has no declaration and is not explicitly instantiated does not pass the sniff-test.
Thanks.
<mx:Script>
<![CDATA[
   import mx.messaging.messages.AsyncMessage;
   import mx.messaging.messages.IMessage;
   private function send():void
    var message:IMessage = new AsyncMessage();
    message.body.chatMessage = msg.text;
    producer.send(message);
    msg.text = "";
   private function messageHandler(message:IMessage):void
    log.text += message.body.chatMessage + "\n";
]]>

Hold your nose, because that is the dynamic "feature" of Actionscript. Pretty much every class derives from Object (http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/Object.html) which is a dictionary of key-value property pairs. The {"chatMessage", msg.text as Object} pair is created upon assignment.
I am fairly new to Flex/AS, and while not having to declare types is convenient for quick and dirty coding, I try to avoid it in production code...I have been bitten by refactoring a class and not catching all the places where it was referenced dynamically. I'm sure there are comprehensive pro and con arguments out there.

Can somebody give me the formula for the balance column in a check register please? I am trying to setup like sample in iWork but am missing something.

Can somebody give me the formula for the balance column in a check register please? I am setting the register up like the sample in iWork 09 but I seem to be missing something in the formula.

OM,
The way the checking account balance column works is to designate one cell for the starting balance, indicate income with positive figures and outgo with negative figures, summing the transactions and adding the sum to the starting figure.
The formula used, =$F$1+SUM(OFFSET(F3,3-ROW(),-1,ROW()-2)), is not too difficult to understand if you study the syntax for Offset. The author of this template didn't do us any favors because the expression could have been written more clearly, in my opinion. I'll explain how it's done in the template, and then how I would have written it. With the two approaches you may be able to see what it's all about.
$F$1 is the starting balance.
SUM requires a Range specification.
Offset provides the range specification. The syntax for Offset is as follows:
Base Cell. In this case it is F3, the cell the expression is written in.
Row Offset. In this case the author takes the current row number and subtracts the starting row from it. For the first balance the offset will be zero since the first balance is in row 3. For all the subsequent balances, the offset will be negative, meaning that the offset will point to a row above the current row.
Column Offset. In this case the column offset is 0. That means that it is pointing 1 column to the left, Column E.
Rows. This parameter sets the length of the range, in rows. Subtracting 2 from the current row number means that the range will be 1 for the first balance and will grow by 1 for each entry down the list.
Taking all this into account, the range for the Sum function will always be Column E from Row 2 to the current Row.
How I would have written the balance expression:
=F$1+SUM(OFFSET(E$3,0,0,ROW()-2))
I believe it's easier to follow.
The starting balance is still in F1, but only the row needs to be absolute - a fine point, I know.
In my expression the base cell for the Offset function is the first entry cell of the transactions, E3. The row needs to be absolute, there is no reason for the base cell to move about as it does in the author's version.
In my approach, both the row and column offsets are zero. We always start at E3.
In my approach, the number of rows in the range is the current row number minus 2, just as in the author's expression. That means we include all rows from Row 3 to the current row.
I'd be happy to answer any other questions about the specifics, but you need to be specific about what you don't get.

Have you upgraded to iPhoto 9.6 for compatibility with Yosemite? If not, try that first.
It looks like iPhoto has lost the connection between the thumbnails and the original image files.
This can be caused by a corrupted iPhoto library, or the originals have been deleted or moved.
Try first to rebuild your iPhoto Library:
If you do not have a current backup of the iPhoto library, make a copy of the library, but do not overwrite any previous backup.
Launch iPhoto with the ⌥⌘-key combination (option-command) held down.
Select "rebuild" from the first aid panel. This may take a while for a large library.
Can you now see your photos again?
If not, rebuild the library with iPhoto Library manager as described by Old Toad: Re: iphoto crashed
