What exactly does the M7 coprocessor do in the iPad air, and what apps can use it?

I've been trying a few 3rd party apps which use the m7 in the iPhone 5s. None of them work. Also there seem to be no apps both built in motion activity under the privacy menu in settings.
My question is, what exactly does the M7 coprocessor in the ipad air?

TS2755 When will Apple ever make it convenient for the customer, I just bought an iPad Air and I'm very upset that I can only use iMessage, iPads are the biggest mistake to buy. I'll never buy another if I can text using SMS or MMS

When will Apple ever make it convenient for the customer, I just bought an iPad Air and I'm very upset that I can only use iMessage, iPads are the biggest mistake to buy if you like texting family and friends. I'll never buy another one if I can't text using SMS or MMS. Is there any hope for a patch or new operating system to fix this issue, or an app to use with iPad Air

[SOLVED] What exactly does gcc's -Os do with the code?

Hey all,
The application that sets my statusbar in DWM, written in C, recently starting segfaulting after I changed the code (commit). I initially traced it down to being that I specify -Os to gcc in the Makefile (without that, it runs fine) and then I traced it to the perc variable in get_battery. If I stop sprintf'ing that into buf, it also doesn't segfault.
This made me start digging through the gcc documentation and now I'm stuck with two questions:
1. What does -Os do exactly with my code? I.e., does it only reduce the size of the binary (how?) or does it also do some optimization as -O1/2/3?
2. Is another optimizer (-O3) "better" than -Os? The code runs fine with this, for example.
Thanks in advance for your insights!

@Karol: yes, I read that, but it doesn't really clarify (to me at least) what it does with the code or why this could cause a segfault.
@Hiciu: Here is the output:

Do you need "set solib-search-path" or "set sysroot"?

It doesn't seem to be segfaulting with perc, but rather in my call to XStoreName... strange. Especially strange because before I restructured my code, it never segfaulted with -Os. I will double check my commit to see if I changed something...
@Trilby: Indeed I think it's there from when I forked this from you - at least, I don't remember adding it myself. I'm also questioning now why one would have that, if it doesn't optimize the program anyway.
@jdarnold: Yes, I compile my code with both -Wall and -Wextra. Here are all the options I pass to gcc in the Makefile:
CFLAGS = -Os -pedantic -Wall -Wextra -Wno-format-zero-length
Those -Wno-format-zero-length I added just to supress warnings about sprintf'ing an empty string into buf, when for example I have no music player running.
I guess I will just remove -Os, but I'm still curious as to why it is causing a segfault.

I downloaded the newest version of 7.0.6.to my ipad air and now I can not connect to safari or any other online app. I get a trust this computer message? and I say yes(its mine) and then it says the software update in unavailable.

Since I downloaded 7.0.6. update I can not connect to the internet. I want to remove it but the ipad air is not showing up in itunes. I get a message do you trust
this computer, yes, and then I get software update in not available. What is wrong?
Please help me.
Thank You

Since my last software update the auto rotation on both my ipad air and my iphone 5c won't work. I have tried everything, including; checking the auto-lock - it isn't on lock. I've checked the settings in the Control Centre and they're as they should be.

Since my last update the auto rotation on both my ipad & my iphone has stopped working. I've done all the usual stuff to correct it but no joy. I've reset, rebooted, turned off then back on, checked all settings including those for the side switch and everything is as it should be except the rotation still doesn't work. There are no open apps, movies or videos that could be locking the screen so I am now totally stumped.
Any suggestions please?

The fact that gs.apple.com was in your host file to begin with is an indicator that your computer was used to jailbreak or hack an iOS device at some point in the past. You can not get help here for a hacked or jailbroken device. If your phone was hacked or jailbroken, Apple won't touch it.
RecBoot and Tinyumbrella are hacking tools.
Google "iPhone DFU mode".
Try restoring in DFU mode. If that doesn't fix it, make an appointment at the genius bar and see what Apple has to say about it.

Apple_Boot Recovery HD partition - what exactly does it do?

On a new MacBook Air (Mid 2011) there is a partiton on the internal solid state drive that shows up (you can see it by using Terminal, then type "diskutil list" at the prompt) as Apple_Boot Recovery HD 650.0 MB disk0s3.
My question is what exactly does this partition provide? Is the Internet still required to accomplish a "Reinstall Mac OS X"?
Does the partition just provide a quick way to reach the Mac OS X Utilities pane (see below) when restarting your computer while holding down the Command and R keys?
If the partition is not on a MacBook Air (Mid 2011) do you reach exactly the same functionality when you are required to download the Mac OS X Utilities pane from the Internet?
Once at the Mac OS X Utilities pane, would you be required to use the Internet to accomplish a "Reinstall Mac OS X" even with the presence of the the Apple_Boot Recovery HD partition?

2. You can boot from any Recovery HD regardless of its location provided it's connected. For example you can use the Lion Recovery Disk Assistant - OS X Lion: About Lion Recovery Disk Assistant - to put a Recovery HD volume onto a small USB flash drive with at least 2 GBs of space. You can install Lion onto a 16 GB USB flash drive in which case the installer will include a Recovery HD partition.
3. If you boot from the Recovery HD then the reinstallation is by Internet. If you have your own bootable USB Lion flash drive, then the reinstallation will take place from the flash drive. Here's how the flash drive is made:
Make Your Own Lion Installer
1. After downloading Lion you must first save the Install Mac OS X Lion application. After Lion downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the Lion installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing Lion.
2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:
Open Disk Utility in your Utilities folder.
After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
Click on the Erase button. The format process can take up to several hours depending upon the drive size.
3. Locate the saved Lion installer in your Downloads folder. CTRL- or RIGHT-click on the installer and select Show Package Contents from the contextual menu. Double-click on the Contents folder to open it. Double-click on the SharedSupport folder. In this folder you will see a disc image named InstallESD.dmg.
4. Plug in your freshly prepared USB flash drive. You are going to clone the InstallESD.dmg disc image to the flash drive as follows:
Open Disk Utility.
Select the USB flash drive from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the USB flash drive volume from the left side list and drag it to the Destination entry field.
Drag the InstallESD.dmg disc image file into the Source entry field.
Double-check you got it right, then click on the Restore button.
When the clone is completed you have a fully bootable Lion installer that you can use without having to re-download Lion.

HT4859 when you go to do this it say that your iPod or whichever device will no longer be backed up to the computer it is currently backed up to, what exactly does that mean? Will i not be able to sync my iPod from that computer?

when you go to do this it say that your iPod or whichever device will no longer be backed up to the computer it is currently backed up to, what exactly does that mean? Will i not be able to sync my iPod from that computer? Please help me and answer either or both question detailed thanks

Normally when you sync your device it is automatically backed up to your computer as the first step in the sync process. When you choose to start backing up your device to iCloud, iTunes stops automatically backing it up on your computer when you sync. That's what the message is telling your; that you are now backing up to iCloud and not to your computer each time you sync. You can still manually back up to your computer any time you want by going to the Summary tab and clicking on Back Up Now under Manually Back Up and Restore.
You can still sync your device as you did before, it just will no longer back up automatically when you do.

What exactly does the AppleCare cover for MacBook Pro with Retina Display?

I purchased the extended protection plan for my MacBook Pro with Retina Display 15" and my question is what exactly does it cover in what kind of situations (i.e. viruses, damaged ports, damaged charger, etc.)? I want to be able to take full advantage of the protection plan since it was a pretty big whole in my wallet.

AppleCare covers all the problems you have with your MacBook Pro with Retina display and the peripherals which came with it (your charger) if you have a hardware problem that you didn't cause. For example, after 2 or 3 years and 1000 charges, OS X says that your battery has to be replaced: in this case, you have to pay for the battery, because batteries have got a lifetime, and Unibody Macs batteries have got an average lifetime of about 1000 charges.
However, if the RAM gets damaged and you haven't done anything to cause it, you will get your computer repaired or replaced for free. AppleCare in a MacBook Pro with Retina display is very important, because near all the parts are soldered into the logic board and repairs are expensive

My iPhone 4s was stolen this weekend and I did the Remote Lock. What exactly does that do? Also, if i do the Remote Wipe will that erase all of my data and impede anyone from ever using the phone?

My iPhone 4s was stolen this weekend and I did the Remote Lock. What exactly does that do? Also, if i do the Remote Wipe will that erase all of my data and impede anyone from ever using the phone?

The remote lock locks the iphone with a passcode that you set. By remote wiping the device it will simply restore it and clear it of all its data, but by doing this it will prevent you tracking it and communicating with it (e.g. remote locking it) in the future

So what exactly does limited to "one app" mean with a Pro account and the new prices?

So it seems Pro has dropped in price but it is now limited to "one App".
So what exactly does that "one App" mean?
Only one tablet version or one phone version for a certain title?
Or you can have a tablet & phone version including android & iOS for that one title?

I think that everyone received it just now…
Changes to Adobe Digital Publishing Suite, Professional Edition
Effective immediately, all customers who newly purchase or renew Digital Publishing Suite (DPS), Professional Edition, will be able to publish only one app per license of DPS Professional Edition.
Under this policy change, Professional Edition customers can publish an unlimited number of issues (.folio files) to a single app and distribute those issues based on purchased fulfillment bundles.
An app created with a single license of DPS Professional Edition can be distributed to any or all of the marketplaces that DPS supports, including the Apple App Store (and Newsstand), Google Play, Amazon Appstore, and the Windows Store.
In conjunction with this policy change, Adobe is reducing the price of a Professional Edition license to $4,800 USD annually (€3,600/¥480,000) or to $400 per month (€300/¥40,000) and will include 1,000 fulfillments annually. The number of fulfillments included with a monthly subscription remain unchanged.
This policy does not apply to test or demo apps published using Professional Edition. The one-app-per-license policy applies only to an app published to a supported marketplace(s).
If you are an agency, upon your renewal or purchase of Professional Edition, you can create only one app per Professional Edition license. If you have multiple clients for whom you are creating apps, either you as the agency or your client must purchase a Professional Edition license for each app published to a supported marketplace(s).
If you are an existing Professional Edition customer and choose to renew your Professional Edition license at the end of your annual agreement, these changes, including the lower price point and 1,000 fulfillments, apply at that time. These changes do not apply to your existing DPS Professional Edition agreement and take effect only if you renew your license.
DPS Professional Edition customers can continue to create unlimited Single Edition apps, which is unchanged under the new policy. A Single Edition app is defined as an app that includes one built-in or embedded folio.
If you expect to publish three or more apps annually, we encourage you to contact your local reseller to discuss pricing for a multi-year Enterprise Edition license.
Enterprise Edition offers additional functionality and benefits not available through Professional Edition. These include app customization, integration with back-end business systems, in-app marketing tools, targeted content based on user entitlement, and the ability to publish apps privately.

What exactly does the Radio Beacon Indicate

I have seen cases where the Radio Beacon is black and when it is gray. When it's black you may or may not be able to go through the wireless router to the modem and then to the internet. When it is gray, you cannot really do anything except be in a local mode. However there are instances when the Radio Beacon is black, rather than gray, and you still cannot access the internet. So, what exactly does the activated Radio Beacon Indicate, i.e., that the wireless network is working and the modem is down, or something else entirely ?

Assuming you're referring to the Airport icon in the menu bar, 'clear/empty' means Airport is turned off, gray bars means Airport is on but not connected to a network, and black bars means Airport is on and connected to a network. Other possible icon states are solid gray with a little computer inset, meaning you're connected to a computer-to-computer created on the Mac, and gray bars with an exclamation point (10.6 only), meaning connected to a network but not authenticated (e.g. wrong password for an 801.2X corporate/university network).
To your question, it's perfectly possible to be successfully connected to a network (black icon) and unable to access the internet. Situations like that would include the network requiring a proxy server, for which you haven't set up the details on in Network Preferences, or you're connected to an open network that requires you to enter information or agree to terms (e.g. a hotel network, where you need to put in your room number and agree to the charges before you can connect to the internet).

What exactly does the global switch command line do ?

Hello All
Just foraging in the dark world of APP-V. I have a question which I cannot find answer for through google.
There are powershell commands to publish an APP-V application globally. What exactly does the global switch do ?
I understand it makes the application available to everyone on the machine for anyone who logs onto that machine.
However in the absence of this global switch the application is still available to all users who logon to that particular machine. So what exactly is the reason for using the global switch ?
Thanks

Correct, the global switch makes the application accessable for all users logging on to that system.
This feature is required for some packages, like Office. But it is ofter used for applications used by everyone, like Adobe Reader.
However in the absence of this global switch the application is still available to all users who logon to that particular machine. So what exactly is the reason for using the global switch ?
A package can be added to the system but until it is published a user cannot start it. They won't see any shortcuts in their startmenu/desktop/etc.
So after you added the package to the system, it must be published to a user or globally (every user) to start it.

What "exactly" does the Brightness setting in Print do?

What "exactly" does the Brightness setting in the Print module do?
I know it's a controversial button, especially now that there are proofing options available. Also, since you're using it "blind" it's impossible to know how much or what it's really doing.
Does anyone know if it's e.g.. the same as going to quick develop and going up on "exposure", or "brightness", or "shadows"... How exactly is it brightening the image, and is +100 a full stop or how is it calibrated?
Thanks,
Alan.

Ooops,
Obviously there is NO brightness control in LR...is the print adjustment similar to an exposure adjustment or more like moving the "shadows" and "whites" adjustments (which if I understand corrrectly, moves tones above or below mid tones, but not highlights or blacks)?
