Clearing my cache,why do I need to do this & consequences

Hi, I am new to iPad, I have an ipad4. I am not great on techy stuff.
The Admin of a site (one of my Spanish expat forums) suggests I clear my cache as his site does not show as it should on my iPad, it shows fine on his. I don't have this problem with other sites so I'm loathe to do what he says. Won't clearing my cache lose me everything on iPad? I need advice please?

On iPad you can delete history, cookies and data. Tap Settings > Safari. Tap to clear cookies, history, and data. < same as clearing the cache.
No, clearing the cache does not delete everything on your iPad.
Keep in mind, not all websites render the same on an iOS device such as your iPad as they will on a Mac. Two different operating systems. Mac OS X vs iOS.

Why do I need to catch this exception?

Hello all
This is a question about exception handling. I have to build a diary application that lets you save reminders on particular dates using xml. Just to make it a little tougher, I was not allowed to use the Calendar class. This is the code I wrote:

}My question is, why does the exceptions in the example code not need to be caught? And why do I have to catch the exceptions in my code? Several exceptions are thrown in the example code, but there is no catch statement.
Thanks for any advice!!

Since your question didn't come with any relevant details, and since you have huge steaming piles of irrelevant code, all I can give is a general answer to "Why do I need to catch this exception?"
[url http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html]Exception tutorial at http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html
Here's a quick overview of exceptions:
The base class for all exceptions is Throwable. Java provides Exception and Error that extend Throwable. RuntimeException (and many others) extend Exception.
RuntimeException and its descendants, and Error and its descendants, are called unchecked exceptions. Everything else is a checked exception.
If your method, or any method it calls, can throw a checked exception, then your method must either catch that exception, or declare that your method throws that exception. This way, when I call your method, I know at compile time what can possibly go wrong and I can decide whether to handle it or just bubble it up to my caller. Catching a given exception also catches all that exception's descendants. Declaring that you throw a given exception means that you might throw that exception or any of its descendants.
Unchecked exceptions (RuntimeException, Error, and their descendants) are not subject to those restrictions. Any method can throw any unchecked exception at any time without declaring it. This is because unchecked exceptions are either the sign of a coding error (RuntimeException), which is totally preventable and should be fixed rather than handled by the code that encounters it, or a problem in the VM, which in general can not be predicted or handled.

I have windows 7 and I can't sign into ITunes. Message says to turn off compatibility mode to use. How and why do I need to do this?

I have Windows 7. I was previously using Windows 98 when I set up ITunes and developed a library of music and movies. When I try to log in I keep getting a message stating that am using an older version of Windows and that I need to turn off "compatability mode to use ITunes. Where and why do I need to do this?

How can I prevent deleted mail from ending up in "All Mail" and "Archives"? To my horror, I've emptied these boxes and lost all my mail from all my boxes (and why do I need to enter this question three times?"

How can I prevent deleted mail from ending up in "All Mail" and "Archives"?
To my horror, I emptied these boxes and lost all my mail from all my boxes .
All mail also disappeared from my iPad, I suppose because they are "synched"
(Also, no offense, but why do I need to enter this question multiple times?)
Thanks for any thoughts.

I'm having a similar but slightly different problem. My company just migrated to Gmail, and it's saving mail drafts every 30 seconds into my Trash folder.
I unchecked the "Show in IMAP" preference in the Gmail settings, but my Drafts folder completely disappeared. I went back and checked it and the folder reappeared (with my drafts still in there).
I like the idea if starting an email on my laptop and having the option of finishing it on my iPhone or iPad, so only saving Drafts locally would not be ideal.

BTXTAXT - Why do we need to maintain this table

Experts,
Could anyone explain why do we need to maintain this Tabe (BTXTAXT) when a new Tax type is added.
I haven't maintained that still taxes are calculated properly for the new tax type87.

Hi, 
It is for "Tax Category in BSI". This is not to be maintained by us ANY TIME and NEVER should be.
The tax type already maintained in BSI and in SAP in the T5UTT table.
This is for SAP to communicate to BSI internally.
Good luck 
Thanks,
Amosha

What is Airport Utility and why do I need to access Airport witeless devices in order to backup my iMac using Time Machine...HELP!!! PLEASE??

AirPort Utility is required to configure an Apple AirPort Base Station or Time Capsule.
Time Machine can use a Time Capsule or a locally connected volume. You only need to use AirPort Utility if you are using a Time Capsule.

HT201413 I get error 20 when I try to download updates to installed Apple software I have two users on the IMac. I resolve the problem by clearing all cookies on both users Safari. Why do I need to do this? What is going on?

I get Error 20 when I try to download updates for installed Apple apps on my IMac. I have two users on the IMac, and I resolve the problem by clearing all cookies on both users Safari, opening and closing the App Store for each user, shutting down and restarting the IMac for each user, until finally the download works. There must be an easier way. I also have an Air, where I have no problems whatsoever. Both machines have Doorstop and MacKeeper with the same settings, so I have ruled those programs out as the cause. I believe iot is because I have two users - any ideas?

Please read this whole message and be sure you understand all of it before doing anything. Back up all data before making changes to your settings.
Write down the server addresses.
Click Cancel to close the Advanced sheet. Unlock the preference pane, if necessary, by clicking the lock icon in the lower left corner and entering your password. Open the DNS tab again and change the server addresses to the following:
8.8.8.8
8.8.4.4
That's Google DNS. Click OK, then Apply.
In Safari, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. If you’re using another browser, empty the cache. Test. Any difference?
Notes:
1. If you lose Internet access after making the above change to your network settings, delete the Google servers in the Network preference pane, then select the TCP/IP tab and click Renew DHCP Lease. That should restore the original DNS settings; otherwise restore them yourself.
2. I’m not advocating Google or anything else as a DNS provider; the server addresses are offerred merely for testing purposes. There may be privacy and technical issues involved in using that service, which you should investigate personally before you decide whether to keep the settings. Other public DNS services exist.

Why do I need to "pushstart" this Sawtooth?

I just bought a Sawtooth from a thrith shop for $25. It was dead, had no RAM, and no Drives, but that was ok since I planned to swap the gear from my Blue & White. The RAM from the Blue & White didn't work, but the power supply, and a new 512 meg stick of RAM got it to start, but only after I pressed the "button" on the inside at least once. It seems to work fine; it boots into both OSX and 9.2.2. The only cards in it now are the original ATI, and the first SATA card from Firmtek. Why won't it start from the front button unless the button on the inside is pressed one or more times?

It's really annoying because it's only happened recently. I bought something on a game for 69p and now it won't work at all for any free apps, help?!?!

No one here can help you. You'll have to contact iTunes support to see what's wrong with your account & how to fix it:

Why do I need Quick time 7 and Quicktime 10 ?

I have just migrated from iMac5 (2.16 GHz) Mac OS 10.4.11 Quicktime 7.6.4 to a new imac 3.06 Mac OS 10.6.2 Quicktime 10.0.

All the files play on the old mac. Why isn't Quicktime forward compatible or why is there no import facility so that you can make your old files compatible ?
Or am I missing something ?

Because your system thinks you are missing specific codecs required for the playback of certain compression formats. In some cases this may be an installation problem in which the codec was "lost" or "orphaned" during the update process. In others it may be a need to update the component to work properly under the dual QT X/7 framework installed under the Snow Leopard OS. You need to check the Inspector/Finder Info or similar window to determine what specific codec is causing the problem and then re-install or update that specific codec/component/package.
(There seem to be a lot of problems with this looking at the forums).
Most of the problems are "self-inflicted" by individuals who, rather than studying the problem symptoms, analyzing them to determine their cause, and then fixing the problems, elect to immediately delete and re-install software -- often attempting to mix components from different operating systems and/or update versions of the software in their haste.
All the files play on the old mac. Why isn't Quicktime forward compatible or why is there no import facility so that you can make your old files compatible?
I am running both Leopard and Snow Leopard variations of QT v7.6.6 and all of my "old" files have remained compatible -- to include MPEG-2 video and a limited number of third-party supported compression formats. Since my configurations continue to work properly, my first guess is that you have an unresolved configuration problem or inability for your QT X 64-bit routines to communicate/switch properly with the 32-bit routines as required for your content.
Why do I need Quick time 7 and Quicktime 10?
Technically, you probably don't. However, as an old QT 7 Pro user who likes many of the QT 7 Player controls/options/features better than QT X's new but more basic features, I maintain both in active service and tend to use QT 7 as the default player of most of my work flows. Still, this is up to the individual. I am in no hurry to rush the changeover from an older but still more reliable QT technology to a more modern, but as yet, less mature and well tested "new" QT technology. In short, I feel it best to make the most of both dispensations during the development of this "new" version of QT.

Why do you need an f after a float initializtion?

When you make a declaration and initialization of a float, you have to put an f after the number, correct?
Like
float productPrice1 = 285.00f;
why do you need to do this and do you need to do it in an assignment operation to?
productPrice1 = 285.00f;
What about for doubles? Would I need to use a d in place of the f?
thanks

What about for doubles? Would I need to use a d inplace of the f?
No, you need to do that to tell the compiler it is a
float, not a double. When assign to a double, you
don't need to tell the compiler it is a double. :)although nothing bad will happen if you do use a 'd' or 'D'.
Good luck in learning Java.

Two Clear System Cache Needed in Two Days since 602 Update

I found out why my battery is worse with the 602 update. Appararently my phone is NEVER GOING TO SLEEP. I forget the name of the service that was keeping it awake. I think it was com.motorola.service.main. After the clear cache, it was good for a day. I took a couple of phone calls and exchanged some text messages and noticed again that my phone was warm. Sure enough, it was stuck again (100% AWAKE even when screen was off for long periods). I cleared the cache again and it has been fine overnight.
I really hope we do get another update because this one is not working too well on my phone (which had few issues with the prior 596 update).

You need to look at what you have installed.....if you have done a factory reset, leave all your apps off for a day and see if the phone itself is draining the battery. I just did a factory reset this past weekend (8/27) and before that, my battery use was attrocious, but after the reset it's not using up the battery as much. Before the factory reset, I had AFK (task killer) installed and I really think it was draining my battery, along with WeatherBug. I don't have those installed after the reset and I see a remarkable difference. Before it, I was having to charge my battery at work by the time it was noon (it sits on the charger at night so it has 100% when I leave for work), but since the reset, I have not had to hook it up to the charger at work. My battery mode is set to performance mode and that doesn't seem to make a difference, even though alot here would say it is gonna drain it the most.
You just have to play with it and see what works and what may be causing it, if that means taking off apps completely and putting them back on one by one to find any differences.

I am a Flash developer. When I change a Flash file (SWF) and try to test it, Firefox displays the previous version even though I have cleared the cache. Clearing the cache obviously doesn't clear everything. Why?

I developed a Flash file (SWF) with a light blue start button, placed it on a web server then went to the URL using Firefox (3.6.8). Later I updated the SWF (changed the button to dark blue), replaced the SWF on the web server, opened Firefox and used Tools/Clear Recent History... to clear the cache. Then when I went to the URL to test the replaced SWF it clearly opened the previous version (light blue button). How can that happen if the previous version no longer exists on the web server? Firefox can only be opening the file from its cache, so why is the file still there if I just cleared the cache?

Your not alone!
I had the identical issue with iPhone config Utility on windows 7 64bit.
A virtual macOS on the same machine didn't have a problem, windows iTunes didnt have a problem. Just a glitch with ICU on windows
I tried everything you did and the only thing that fixed it was to change the appID or app name (I forget which I did).
I don't know where that old app data is stored on the machine, but I deleted all apps, uninstalled/reinstalled ICU and it still would populate and install the old ipa.
I also still periodically get weird errors/glitches deploying to iOS on windows.
It's like some days I need to deploy with ICU, sometimes iTunes, sometimes I need to run the VM mac... SOO frustrating.
It always works one way or another, so the app itself is always fine.
I guess I really need to look into that new direct deployment option...

Clearing my cache,why do I need to do this & consequences
