Safari optimization in the wake of this AT&T plan nightmare
I'm in a remote cabin and am stuck with EDGE so I've really noticed Safari's lack of caching. Anytime I open new tabs and then go back I have to wait for a re-render as all the data is downloaded again. It may not be as noticeable on 3G but the data still adds up especially for those that do lots of browsing. As far as I can tell Safari only holds maybe two or three tabs in cache, less if you hop over to another app. By contrast iCabMobile seems to do a MUCH better job as it seems to save an archive of each page. I'm not exactly certain how they it works but I can load up 7-8 tabs and the reload is nearly instant. If the guy (I think it's just one guy) doing iCab can do this I'd think Apple could.
I've got a little hope that Apple might fight to keep their "deal" with AT&T and think they should, especially for iPad users. I don't know what Apple can do or if they'll make the effort to defend the iPad unlimited data but regardless, I hope they'll do something to inprove the Safari user experience. Saving data bandwidth is all the more important if we end up being stuck with these new caps. I'd encourage folks to give Apple some feedback on this.
I have been using the "atomic browser" for more than a month now. It not only uses real tabs, but allows background loading of tabs, and the ability to turn off images so that you just get text and the pages load alot faster as well as saving bandwidth. I still had more than 20Mb left last month on a 250 plan.

I have mobile me mail service. Use mac 10.6.7. Have latest firefox. Suddenly only can get "find my phone" - not mac mail - even when I type in the mac.me or mobile me mail in the browser window. Safari seems to work fine.
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

When we get the actual data in BPC for planning, is the data consolidated
I had a question regarding Planning. When we get the actual data in BPC for planning, is the data consolidated? Do we need to run the consolidation business rules( IC Booking, Matching, IC Eliminations) on the data before we can use it for planning? Per my understanding we have to run Currency Conversion on this...correct?
Also, where do I get my actual data from? Does ECC/ Source system have data from all entities( CHQ, Region and Countries)?
Please help!
Thanks in advanceHi Kimi,
In a hierarchical structure, the data is always loaded in to the base level, and the data is automatically rolled up to its parents.
The currency conversion will also take place at the base level, and as mentioned earlier, the converted data will also be rolled up as per the hierarchy.
The heading of this thread says planning. So, ideally, there wont be any legal (or statutory) consolidation. You might use the US elimination however, for eliminating the intercompany transactions, if any.
The planning can be done as zero based (wherein the user has to enter the planned data manually from scratch) or non-zero based (wherein the planned data of previous year is copied and the user can change the data as required).
The flow of events cannot be suggested by us. It has to be discussed with the business to understand how do they do the planning.
Hope this helps. -
when I try to get on the internet thru safari at home, on my network, I get a pop up that says Safari cannot open the page because it is not connected to the Internet. How can this be and how do I fix it?
Does the iPod connect to other networks?
Do other device connect?
Did the iPod connect to this network before?
Try:
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router

How can I correct the issue of Safari not connecting on my iPad Air? It was working great 2 days ago.....now on September 20 it is not working! I have an internet connection but Safari will not open. "Safari cannot open the page because it could not connect to the server."
Hello Beckieor,
After reviewing your post, I have located an article that can help in this situation. It contains a number of troubleshooting steps and helpful advice concerning network issues:
iOS: Troubleshooting Wi-Fi networks and connections
Follow these steps to troubleshoot the above issues:
Be sure you're in range of your Wi-Fi router (access point).
Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your Wi-Fi setting is dimmed, follow these steps.
Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
Restart your iOS device.
Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
Tap and Forget this Network.
Try to connect to your desired Wi-Fi network.
Note: You may need to enter your Wi-Fi password again if your network requires one.
Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
Thank you for contributing to Apple Support Communities.
Cheers,

osx 10.7.4 safari 6.0 When I add a new bookmark to the "bookmarks menu" it is added somewhere in the middle instead of at the end of the list. This just started a few days ago after an update. Has anyone else noticed this?.
Just for those who are interested, this is what cleared the "bookmark menu" trbl I had.
Open System Preferences > iCloud
Deselect the box next to Bookmarks, then reselect it.
Quit and relaunch Safari. Try a bookmark again. -
when i try to download the software onto my mac, i receive a message saying that safari cannot open the specified address as OS X does not recognise the internet address starting with "aam". Please please can someone shed some light on this, its driving me MAD!!!
Try and download the Desktop Application First before trying to install any other Adobe Product. The link for AAM is Safari looking for Desktop Application in your machine.

I have problems saving pdf files in the web when I use Safari. I don't have this problem with firefox.
do they save ok if Safari - Preferences - Security - Allow all other plug-ins is unchecked ?
If so, likely an adobe or other pdf plugin
Re-check the setting above & quit any browsers,
Look in this folder by triple-clicking the line below, then ctrl-clicking it & choosing Services - Open
/Library/Internet Plug-Ins/
remove anything with pdf in the filename & test again
Sometimes, plug-ins can be in the User Library folder :
~/Library/Internet Plug-Ins/ -

How to optimize the performance of this code ?
I've two Movie clips on a flash project. One of them is fixed and the other can be moved by arrow buttons on the keyboard. The two Movie clips have irregular shapes, so HitTestObject and HitTestPoint doesn't work very well. I've a function that detects collision of two movie clips using bitmap. I wanted to update the position of the movable Movie clip so I put the collision detection function under the code of ENTER_FRAME event listener. It works very well, but when I add many fixed movie clips ( about 10 fixed movie clips in one frame ), the game (.swf file) becomes slower and the performance of the PC becomes slower. I thought that my collision detection function has a negative effect on PC performance so I used the class on this page : https://forums.adobe.com/thread/873737
but the same thing happens.
Would you tell me how to speed up the execution of my codes ?
Here is part of my code :
stage.addEventListener(Event.ENTER_FRAME, myOnEnterFrame);
function myOnEnterFrame(event:Event):void
if (doThisFn) // doThisFn is a variable to allow or prevent the movable movie clip form being moved with keyboard arrows
if ( left && !right ) {
player.x -= speed;
player.rotation = player.rotation - speed ;
if( right && !left ) {
player.x += speed;
player.rotation = player.rotation + speed ;
if( up && !down ) {
player.y -= speed;
if( down && !up ) {
player.y += speed;
// The fixed movie clips are wall1 ,wall2 , wall3 , wall4 , ... and so on
// the following code checks how many walls exists on each frame and pushes them into the wallA array
for(var i:int=0;i<1000;i++) // We can put up to 1000 wall object into the wallA array
if(this['wall'+i]) // If the object wall exists, push it into the wallA array
wallA.push(this['wall'+i]);
for(i=0;i<wallA.length;i++)
if( h.hitF (player , wallA[i] ) || gameOverTest ) // This code checks if the player ( the movable movie clip ) hits the walls or not
trace ( "second try" ) ;
gameOver.visible = true ;
doThisFn = false ;
//I think the following codes are easy to excite and run. I think the performance issue is due to previous codes.
if (player.hitTestObject(door))
win.visible = true ;
doThisFn = false ;
if (key) // if there is a key on frame
if (player.hitTestObject(key))
key.visible = false ;
switch( currentFrame )
case 4:
wallA[0].visible = false ;
wallA[0].x = 50000;
break;
case 5:
wall14.play();
wall8.x = 430 ;
break;it's a simple question that usually has no simple answer.
here's an excerpt from a book (Flash Game Development: In a Social, Mobile and 3D World) i wrote.
Optimization Techniques
Unfortunately, I know of no completely satisfactory way to organize this information. In what follows, I discuss memory management first with sub-topics listed in alphabetical order. Then I discuss CPU/GPU management with sub-topics listed in alphabetical order.
That may seem logical but there are, at least, two problems with that organization.
1. I do not believe it is the most helpful way to organize this information.
2. Memory management affects CPU/GPU usage, so everything in the Memory Management section could also be listed in the CPU/GPU section.
Anyway, I am going to also list the information two other ways, from easiest to hardest to implement and from greatest to least benefit.
Both of those later listings are subjective and are dependent on developer experience and capabilities, as well as, the test situation and test environment. I very much doubt there would be a consensus on ordering of these lists. Nevertheless, I think they still are worthwhile.
Easiest to Hardest to Implement
1. Do not use Filters.
2. Always use reverse for-loops and avoid do-loops and avoid while-loops.
3. Explicitly stop Timers to ready them for gc (garbage collection).
4. Use weak event listeners and remove listeners.
5. Strictly type variables whenever possible.
6. Explicitly disable mouse interactivity when mouse interactivity not needed.
7. Replace dispatchEvents with callback functions whenever possible.
8. Stop Sounds to enable Sounds and SoundChannels to be gc'd.
9. Use the most basic DisplayObject needed.
10. Always use cacheAsBitmap and cacheAsBitmapMatrix with air apps (i.e., mobile devices).
11. Reuse Objects whenever possible.
12. Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.
13. Pool Objects instead of creating and gc'ing Objects.
14. Use partial blitting.
15. Use stage blitting.
16. Use Stage3D
Greatest to Least Benefit
Use stage blitting (if there is enough system memory).
Use Stage3D.
Use partial blitting.
Use cacheAsBitmap and cacheAsBitmapMatrix with mobile devices.
Explicitly disable mouse interactivity when mouse interactivity not needed.
Do not use Filters.
Use the most basic DisplayObject needed.
Reuse Objects whenever possible.
Event.ENTER_FRAME loops: Use different listeners and different listener functions applied to as few DisplayObjects as possible.

Each time I open Safari it opens the last web page I was at rather than my home page. How do I stop this from happening?
This is part of Lion's Resume feature (I assume you are on Lion).
A couple of things you can do: System Preferences>General and deselect 'Restore windows when quitting and re-opening apps'.
Also when you shutdown or restart make sure the following is unticked: -
I can't login to Facebook from the app or on Safari. Is anyone else have this issue? I deleted FB from my iPhone 4 and reinstalled it. Still didn't work.

Safari 5.1.6 won't run on my Pro. It was Safari 6 on the MacBook I transfered the data from. Could this be the problem, and if so, how do I up grade to Safari 6? I can't seem to find any help.
Lion should be running Safari 6. Try Software update. Or apply the Lion 10.7.4 Combo installer:
