What happens if you misswire your speakers AND how can you tell if it is misswired?

The red mark came off the wire and i don`t know which wire was the red one.

Hmmm... the best way to determine which wire is the '+' is by using a electronic meter and do a continuity test. The center pin of the RCA cable is the '+' and the ground is '-'. If you don't have a meter, only way you can try is using music, try to differentiate whether that particular spk does it sound out of phase or correct phase. If out of phase, the vocal will not sound very centerised. Good luck.

What permissions do signed applets get? And how can I tell?

This could be a JNLP question, but it's really about signing versus not signing.
I find that if I sign the applet's jar, I get permissions I don't get if I don't sign it, even though I haven't asked for any permissions. What's disturbing about this is that neither the JNLP spec (look under Launch) nor the Permissions spec (look here [http://download.oracle.com/javase/1.4.2/docs/guide/security/permissions.html#SecMgrChecks] -- I don't know if there's a more recent version) make any mention of signing. (Well, the JNLP spec says you need to sign if you ask for permissions, but I'm not asking for any permissions in the JNLP.)
So, my question is: Where is the set if permissions that an applet gets solely by virtue of being signed documented? Failing that, is it possible to get the security manager to list out the permissions I have?

bump
having the same existential question about the secret mysteries of jnlp applets, I'd be highly interested by the answer :)

I am trying to listen BBC radio news from BBC App, but on pressing the button I always get the error "there was an error playing this radio feed". What is the source of this error and how can I remove it?

I am trying to listen BBC radio news from BBC App, but on pressing the button "live radio" I always get the error "there was an error playing this radio feed". What is the source of this error and how can I remove it?

That is probably just a generic error message and you might not ever know what is causing it. Assuming that you have been able to play live radio with the app in the past (I know nothing about the app) and assuming that all other Internet related functions (Safari, email, etc.) are working properly on your iPad, quit the app completely and reboot your iPad.
Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If that fails to resolve the issue, you might want to reboot your router, unplug it for about 30 seconds and then plug it in again.

When are I-Tunes updates legitimate and how can I tell?

When are I-Tunes updates legit and how can I tell?

I have no idea what you're ranting and rambling about. Your "simple question", if you're referring to the one in this thread, makes little sense other than how I addressed it. If my answer didn't cover your question, post back and clarify what it is you're asking. Don't just come back and post a rant; it's insulting (and the "human" crack doubly so) to all those here, who are just fellow users trying to help out other users and who don't owe you one second of their time.
If you want tech support directly from Apple, you call them; it's that simple. Contact information is linked from the bottom of every Apple web page, including this one.
Geez; the old saying that "no good deed goes unpunished" continues to get proven true every day.

Script to find duplicate index and how can we tell if an index is REALLY a duplicate?

Does any one have script to find duplicate index? and how can we tell if an index is REALLY a duplicate?
Rahul

One more written by Itzik Ben-Gan
The first query finds exact matches. The indexes must have
the same key columns in the same order, and the same included columns but in any order.
These indexes are sure targets for elimination. The only caution would be to check for index hints.
-- exact duplicates
with indexcols as
select object_id as id, index_id as indid, name,
(select case keyno when 0 then NULL else colid end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by keyno, colid
for xml path('')) as cols,
(select case keyno when 0 then colid else NULL end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by colid
for xml path('')) as inc
from sys.indexes as i
select
object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
c1.name as 'index',
c2.name as 'exactduplicate'
from indexcols as c1
join indexcols as c2
on c1.id = c2.id
and c1.indid < c2.indid
and c1.cols = c2.cols
and c1.inc = c2.inc;
The second variation of this query finds partial, or duplicate, indexes
that share leading key columns, e.g. Ix1(col1, col2, col3) and Ix2(col1, col2)
would be considered duplicate indexes. This query only examines key columns and does not consider included columns.
These types of indexes are probable dead indexes walking.
-- Overlapping indxes
with indexcols as
select object_id as id, index_id as indid, name,
(select case keyno when 0 then NULL else colid end as [data()]
from sys.sysindexkeys as k
where k.id = i.object_id
and k.indid = i.index_id
order by keyno, colid
for xml path('')) as cols
from sys.indexes as i
select
object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
c1.name as 'index',
c2.name as 'partialduplicate'
from indexcols as c1
join indexcols as c2
on c1.id = c2.id
and c1.indid < c2.indid
and (c1.cols like c2.cols + '%'
or c2.cols like c1.cols + '%') ;
Be careful when dropping a partial duplicate index if the two indexes differ greatly in width.
For example, if Ix1 is a very wide index with 12 columns, and Ix2 is a narrow two-column index
that shares the first two columns, you may want to leave Ix2 as a faster, tighter, narrower index.

I'm having trouble turning on my ipad and how can I tell when it's fully charged?

I'm having trouble turning on my ipad and how can I tell when it's fully charged?

Try a Reset - hold the Home and Sleep/Wake buttons down together for 15 seconds.
Have you read the User Guide?
Unless the charge indicator has bee turned off you see the percentage charged in the top right of the screen.

Can you read a e-book on your ipod and how can you transfer them ?

I was wondering can you read a e-book on your iPod and how do you do tranfer the e-book to your iPod?
I would appreciate any help,

See same topic (almost) next to this one. You need Acrobat Reader and the iPod is not equipped at this time to run that application.

What is the "Other" category under storage and how can i delete items from this?

My disc is almost full. "About this Mac" says that I have 47 GB of "Other." What is this Other and how can I delete items from this?

For information about the Other category in the Storage display, see this support article.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown asBackups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size with the largest at the top. It may take a few minutes for ODS to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

What are this things in my document and how can I get rid oth them

Hi,
I'm a happy recent switcher, I'm migrating my .doc documents to pages '08 but sometimes I'm getting weird vertical lines and triangles in the pages document.
What are they and how can I get rid of it, cause they get printed. There is no way to affect it using the mouse.

What is wrong with my iphone4? and how can i turn it back on?

About a week ago, i was using my iphone that I've had about 6 months, no problems. It was working perfectly fine and then out of nowhere it shut itself off. I plugged it in, nothing happened. I pressed the home and lock button, and held them in, and still nothing happened. The next day I decided to plug it in again, and it told me to leave it plugged in, like it was dead or something (the red battery symbol popped up, and said it was charging) and about 10 minutes later the iphone came back on. The only problem was that from here on out my home button does NOT work, at all.
The phone was working................ until about 3 days later the same thing happened to it again, except the next day it did not come back on the same way. My mom took it to the AT&T store (living in west virginia, there aren't any Apple stores near by). She came home with it working again, but I have no clue how they got it back on.
A few days after the second time it shut off, it happened again. We took it to AT&T again, and this time they couldn't get it back on, but they gave us some tips. We plugged it into itunes, and restored it. I was over the amount of space. I had no storage left!! So I went through and deleted all my music, and about 500 photos (having around 1,200) . I now have about 700 photos, 20 songs, and roughly 15 apps. ONE day after I did all of this, my phone shuts off for the fourth time !!!! (It is off right now) Seeing how I have 3 GB of space left on my phone, I would think it's not a storage issue.
I've plugged it into the wall charger, nothing! I have tried to reset it holding the home button (which still does not work) and lock button, still nothing. I have now plugged it into itunes. It says the device is found, but not identified please restore the device. So I restore it, but that doesn't help, Itunes still cant "identify" the device and it is still not on.
I have checked for water damage, and there is not any! I just want to know what is wrong with it, and how to fix it. OR maybe if I just need to get a whole new phone, because mine is under warranty. The problem is AT&T won't give me a new one and there isn't an apple store near me! Can someone PLEASE help?

I think you might get a new phone instead of repairing it as it takes time and you said the repairing center is far from your living place

ITunes 12-Please please restore side bar functions for playlists -and how can i tell when and if it is safe to "eject" devices after synching

ITUNES 12-4points
1) Please restore the easy function whereby the side bar easily accommodates playlists
2) How do i know when devices can be ejected following synch--no visible drop down ?
3) How can i change the fonts and font sizes of the library-over and above the noddy large/small toggle in preferences
4) Look forward to a proper Apple update which includes full functions of iTunes radio. Hurry up with the latter-Spotify is overtaking you guys!

How do i know when devices can be ejected following synch--no visible drop down ?
I can only tell you based on what I see w/ my iPhone...
When I plug in my iPhone I get the following icon on the top bar:
If I click on that (that's when it turns blue), I get a sidebar. At the top I see this while it is syncing:
The circle-arrows spin. Once the sync is finished, I see this:
I then know the sync is over and I click on the Eject icon that replaced the circle-arrows.
Are you seeing something different?

What causes iPhone to lose all contacts, and how can I stop it happening again?

iPhone 3gs, still running 5.1.1 because I actually rely on the mapping software.
A few days back, it started randomly exiting various apps for no reason. Today, I tried powering off and re-starting, but when it re-started it had erased all contacts.
Last backup was a couple days before, so I won't have lost anything crucial, but this is the first such disaster since bying the phone 3 years ago. I see numerous complaints about this, and no real solution or explanation offered from Apple. I figure it's about time to replace my phone, so this will be a test: either there will be a clear explanation and a solution, or I'll switch to Android.

What are you syncing them WITH? Do NOT say iTunes. iTunes is NOT a contact manager.
If you're syncing them with your computer, your choices are MS Outlook or Windows Address Book on a PC, and Contacts / Address Book on a Mac.
If you are not syncing your contacts with a contact manager or cloud service, you are NOT syncing your contacts.
See this document: http://support.apple.com/kb/ht4946
Particularly this item and disclaimer:
Contacts* and Contact Favorites (regularly sync contacts to a computer or cloud service such as iCloud to back them up).
* Your contacts are part of the backup to preserve recent calls and favorites lists. Back up your contacts to a supported personal information manager (PIM), iCloud, or another cloud-based service to avoid any potential contact data loss.

What the heck is a "Kernal panic" and how can I fix this?

Lately, several of my partitions (external firewire) running OS 10.3.9 have crashed and are no longer bootable. one partition crashed upon being turned on, and said that there was 'no driver for powerbook 6, 5' and 'kernal stopping here...' I started up from a different partition, and installed the latest security update, and that repaired my kernal, but now for some reason, I am not an 'administrator,' but I am the only user of this computer. any suggestions?
someone had this happen in class, and I found out that the problem that I was experiencing was called a 'kernal panic,' and now I want to know why this happens, how to prevent this from happening, and the best software tool to check the health of my system folder. anyone got any suggestions?
I'm considering installing a clean version of OS 10.3.3, and updating to 10.3.9, but if there is a faster way to fix this, then I'm all ears! thanks!

Patddfan:
From your description of what is happening it does not sound like a kernel panic. See What’s a kernel panic. In terms of what to do see: Resolving Kernel Panics
I suspect that your HDD is in serious need of maintenance. Here's what I would do:
1. Go to Applications > Utilities > Disk Utility. In the left panel select your HDD (manufacturer ID), and in the main panel select the First Aid tab. Click Repair Disk Permissions.
2. Boot from your install disk. Go to the Installer menu and launch Disk Utility. Select your HDD (manufacturer ID) in left panel and First Aid in main panel. Click Repair Disk. If DU reports disk needs no repair quit DU and restart.
If DU reports errors, click Repair again, and again until DU reports the disk is repaired. If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior.
3. Download MacJanitor and run all the procedures, the follow regular schedule.
4. Take a look at Gulliver's article Mac OS X System Maintenance and implement procedures.
Please post back with further questions or comments.
Good luck.

What is an 'SPL-2.dmg' file and how can I get it (the driver) installed?

subject line is question

*My question to Samsung:*
"SCX-4200 driver for Mac OSX.5.5
After downloading the driver from
http://www.samsung.com/us/support/download/supportDownDetail.do?group=&type=&sub type=&modelnm=SCX-4200&language=&cate_type=all&mType=DR&dType=D&vType=L&cttID=2047002&prd_i a_cd=06010300&dispnm=SCX-4200,
the following error message is displayed: 'The following disc images failed to mount - image: SPL2.dmg; reason: not recognised.'
Please advise."
*The reply from Samsung:*
Thank you for contacting us regarding your SCX-4200 and the recent issue you have experienced.
It is difficult to say why this error may have occurred, it may be that the file has been corrupted during transfer. You should try deleting this file again and re-downloading it or possibly even try downloading the file from an alternate location such as below -
http://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=uk&C ttFileID=2047002&CDCttType=DR&ModelType=N&ModelName=SCX-4200&VPath=DR/200810/200 81028145509765/SPL2.dmg
Should you wish to discuss this issue further, please feel free to call our IT Helpdesk on 0845 726 7864 quoting your reference number."
*Having tried all that, I did phone them, only to be fobbed off, +'Try re-installing from the CD you got with your printer. If that doesn't work it must be their ([Apple's]) problem.'+*
My MacBook is trying to mount it, according to right-click 'Get Info', using DiscImageMounter, which only returns the error message (above), 'The following disc images failed to mount - image: SPL2.dmg; reason: not recognised.' Disc Utility doesn't tell me much more. What should I do with it?
My printer (Samsung SCX-4200) clicks and warms up when it's sent a command to print, but that's the end of it - it won't do anything else, which is why I went looking for the driver in the first place. Note the Samsung Download Centre site at _http://www.samsung.com/uk/support/download/supportDownDetail.do?group=printsolut ions&type=printsolutions&subtype=monomultifunctionproducts&modelnm=SCX-4200&disp_nm=SCX-4200&language=&cate_type=all&mType=DR&dType=D&vType=L&ct tID=2047002&prd_ia_cd=06010300 says this driver was updated/uploaded 28/10/2008, but I can't get the **** thing to install. Any idea what I'm doing wrong?
Probably also worth noting: the printer works fine with Windows on my MacBook's BootCamp partition.

What is wrong with my iPod.. and how can i fix it?

ok.. my 5G iPod was working fine.. then i couldnt get it to eject from my iBook.. on my computer screen it said that it was ejected.. but i iPod never said ok to disconnect. a few moments later and my iPod was back on my computer screen.. it did this multiple times..
i eventualy shut off my computer to disconnect my ipod. and that worked fine (or so i thought)
i unplugged my iPod and went to go listen to a couple new songs i just put on it.. and it skipped through the songs without playing any of them. (when my ipod was connected to my iBook i was listening to those songs from my iPod and they worked fine)
so it was ******* me off.. i went to go turn off my iPod before i went to bed, but it wouldnt turn off.. so i decided to leave it on my deskfor the night.. it drained my battery.. that didnt bother me too much.. casue i expected it to happen.
so i plug my ipod back into my computer to charge it up.
(the iPod image does not appear in the finder or itunes)
a few hours later i go to check on it.. it just had the apple logo screen up.. so i tried resetting it.. then a screen came up and said "please wait. Very low battery" so i left it alone. i go back to check on it about 6 hours later... same thing happens over and over and over again.
(the iPod still does not appear in finder or itunes)
so what should i do?

Hi,
I had the same problem. charging through the computer didn't work for me and it said (just like at yours) "please wait. Very low battery" without backlight.
I bought a adapter (which I thought had te same power as the USB, but anyway) I charged it with this piece of heaven, and it worked. It needed 1 hour to charge it. (I have a 5G iPod with video btw)
good luck!
