Can i do hardware compare using hsdio when the generation and acq clock rate are different

Hi there
my application should generate a digital stream in clock rate A with bus width (number of bits) very from 1 to 4 bits
The DUT will response always on on bit but with clock rate B.
1. can i use the hardware compare mechanism of the hsdio boards.
2. if answer is YES is there any sample that can help me getting started.
Thanks for advance

Hi,
One good example to use as a starting point can be found in the NI Example Finder. Navigate to "Hardware Input and Output" >> "Modular Instruments" >> NI-HSDIO >> Dynamic Acquisition and Generation >> Hardware Compare - Error Locations.vi. You'll need to explicitly wire in your new rate into the "niHSDIO Configure Sample Clock.vi" on your response task.
There is also a portion of this code that warns if the stimulus and response waveforms are not the same size. This is not necessary, and could be deleted from the program. You are allowed to have different size stimulus and response waveforms.

Do some app publishers allow use of both the ipad and iphone versions, even if different?

Do some app publishers allow use of both the iPad and iPhone versions, even if one is coded differently for the iPad? Buy one and get both.

Thanks,

Their language makes it abiguous. When you go to the apps store there are two versions.

Can I back-up my iphone 4 to the cloud and then sync to a different library and not loose everything?

I've been syncing to my laptop, I got a new one. I used home share to move verything in my itunes account to the new computer. My old one is quickly dying. If I sync to the cloud, can I then restore from a coud back-up and if so, how?

Can i make a book in iPhoto without using any of the built in layout templates, which are too limiting when i have already cropped my pictures to show just what I want. Ideally I just want to drag and drop and arrange and size the pictures myself

If you have Pages you can create customs pages for your book as TD suggested. If you have Pages from iWork 09 or 11 this app will add 80 or so additional frames to those offered: Frames and Strokes Installer. Don't use it on the latest Pages version, however.
This tutorial shows how to create a custom page with the theme's background: iP11 - Creating a Custom Page, with the Theme's Background for an iPhoto Book. Once the page is complete to get it into iPhoto as a jpeg file follow these steps:
Here's how to get any file into iPhoto as a jpeg file:
1 - open the file in any application that will open it.
2 - type Command+P to start the print process.
3 - click on the PDF button and select "Save PDF to iPhoto".
NOTE: If you don't have any of those options go to Toad's Cellar and download these two files:
Save PDF to iPhoto 200 DPI.workflow.zip
Save PDF to iPhoto 300 DPI.workflow.zip
Unzip the files and place in the HD/Library/PDF Services folder and reboot.
4 - select either of the files above (300 dip is used for photos to be included in a book that will be ordered).
5 - in the window that comes up enter an album name or select an existing album and hit the Continue button.
That will create a 200 or 300 dpi jpeg file of the item being printed and import it into iPhoto. For books to be printed choose 300 dpi.

You need to adjust your security stuff/ permissions and possibly use compatibility modes. It means that your licensing service is being blocked/ shut down.

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp

How can I edit lightroom 5 smart previews on mac book pro (mbp) when the lightroom 5 master image files are on my external hard drive is disconnected from the mbp? So far when I try to disconnect the external HD from the mbp, I get the following pop up window: The disk "external hard drive A" couldn't be ejected because "Lightroom" is using it. Quit that application and try to eject this disk again. When I do that and restart Lightroom 5, the Adobe Photoshop Lightroom - Select Catalog screen pops up but doesn't list my external hard drive A as a choice.
I've reviewed Adobe's Lightroom Help | Smart Previews Lightroom 5 web page and still haven't been able to figure what I'm doing wrong. Any help would be appreciated.

Your internal HDD. by default, is named 'Macintosh HD'. From what information you supplied, it looks like there is already a Lightroom catalog installed on you local (internal) HDD using the standard naming convention Adobe uses as well as a Lightroom catalog on your external drive which you created. To be sure of which catalog Lightroom is loading when it starts up, To do this, start Lightroom as you normally would. After it starts, select the Lightroom menu item, then select the Catalog Preferences item and finally, navigate to the General tab. The Location information will tell you exactly what catalog Lightroom is opening by default. This will likely be the Photography Mac Book Pro Versions catalog on your external HDD. Once that is confirmed, you are ready to proceed. As an additional test/verification, you can shut down Lightroom and, this time, start Lightroom while holding down the ALT/OPTION key. This will cause Lightroom to pause and display a screen which will allow you to chose a different catalog to open. Navigate to the /Users/[user name]/Pictures/Lightroom folder and select the Lightroom 5 Catalog.lrcat file. When Lightroom comes up, there should be no previews or folders as this catalog should be empty. Now you can be certain which catalog is being used and which catalog has all your data and you are ready to migrate your current catalog. Shut down Lightroom.
To migrate your current catalog, use Finder to locate your Photography Mac Book Pro Versions folder on your external drive. Select the folder and select COPY from the context menu. Next, use Finder to navigate to the /Users/[user name]/Pictures/Lightroom folder on you internal HDD. You can start at the Macintosh HD level and work your way down by opening each level (Macintosh HD/Users/[user name]/Pictures). Select the /Pictures folder and then select PASTE... from the context menu. When the COPY/PASTE is complete, you should see the following files on the Macintosh HD:
Macintosh HD/Users/[user name]/Pictures/Lightroom/ and
Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions
The Macintosh HD/Users/[user name]/Pictures/Lightroom folder will contain the empty default catalog the Adobe created when Lightroom was installed and Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions will contain a copy of the catalog you created on your external HDD.
You are almost done now. Make sure your external drive is still attached for this step. Restart Lightroom using the ALT/OPTION key again. When the Select Catalog screen appears, select the Choose a Different Catalog button (lower left side). When you do, a Finder window will open to allow you to navigate to a catalog of your choosing. Navigate to Macintosh HD/Users/[user name]/Pictures/Photography Mac Book Pro Versions and select the file Photography Mac Book Pro Version.lrcat. This is the copy you just created. Select the Open button and Lightroom should start. You should see all of your previews and settings just as before. Also, in the left hand panel, all of your folder should show up and none of them should be dimmed and none of your previews should display a small exclamation point badge. Either a dimmed folder name or an exclamation point badge indicates that Lightroom can't find the associated image file. If everything looks good, go to the Lightroom menu, select Preferences and then select the General tab. Under Default Catalog, select an option to either load the LAST catalog opened or select the Users/[user name]/Pictures/Photography Mac Book Pro Versions catalog from the drop down. Shut down Lightroom and then restart it normally. This time, when Lightroom starts, you should be viewing the new copy of your catalog. You can confirm this by looking at the General tab on the Catalog Preferences screen (Lightroom/Catalog Preferences menu items). Shut down Lightroom once again and this time, eject your external drive before restarting. This time, your folders in the left hand panel will be dimmed but you should be able to work with your smart previews. If Lightroom should display a Select Catalog screen with the external drive detached, double check your settings as it indicates Lightroom is still looking at the copy of the catalog on the external drive rather than the new copy you made.
Finally, if you are seeing dimmed folders and/or exclamation point badges with the external drive attached, this indicates a problem. You can select any folder and select Update Folder Location from the context menu. This will allow you to navigate to the copy on the external drive and select it. Lightroom will then update the catalog (select to synchronize the content). This will not only clear the dimmed folder problem but also remove the exclamation point badges for all photos in that missing folder. However, it may indicate that not all went well with the copy of the catalog so make sure to verify all went well. You can use the Get Info option on the two folders. You should see the same number of files/folders for both the copy on the internal drive as well as on the external drive but you can't rely on the byte count because of the possibility of differences between the geometry of the two drives. Hope this all helps!

My iCloud email address and my apple ID are different. I would like to change my iCloud to be the same as my apple ID. However I don't know my iCloud password and don't use the email address it belongs to. When I try to change the password, apple brings me to a page to reset my apple ID password (which I know and don't want to change). I have even tried to delete my iCloud account completely to start again but am not allowed without the iCloud password (which I don't have) there doesn't seem to be a place to change the email address of iCloud. What can I do?

This is the answer that I had expected, so in this case you could only change your gmail.com address to another providers email addres e.g. outlook.com, yahoo.com, etc., but you won't be able to change the gmail.com address to a icloud.com email address. Apple just won't let you do that.
Your iCloud account with @icloud.com email address and you Apple ID with gmail.com address are already connected and as I said before, Apple just let you merge this two IDs together.

You did the wrong things. In the future it's a good idea to remember not to do something when you don't know what you are doing and what happens when you do it.

I lost my ipad, and when i logged in to my apple account, i found another person email. what can i do to trace ? my ipad hasnt been registered with apple before i lost it, can i registered now (as i still have the package) and then supply the serial no.

Hi, just wonder anyone can help. i lost my ipad few weeks ago (already reported to police in UK but they arent helpful), and when i logged in to my apple account, i found another person email added to my apple account (but has not been verified). what can i do to trace ? my ipad hasnt been registered with apple before i lost it, can i registered now (as i still have the package) and then supply the serial no. to apple so they can block that ipad??
i am based in london, but seems now the apple account based in USA.. very strange.
i am using iphone as well, so beforei lost the ipad, when i download apps, it download to both iphone and ipad.
i am not sure what i can do to make apple aware of the lost ipad, as i havent registered my ipad before i lost it. or can i registered now and report a lost??
appreciate any advice..
thanks

The only tracking feature Apple offers is the one tied to your iCloud account (https://www.apple.com/icloud/features/find-my-iphone.html). If you did not have an iCloud account set up on the iPad, or did not have the "find my iPad" setting enabled under that account's settings, then you cannot track it remotely.
There is nothing you can do but hope the police do something, or you find it yourself. Apple does not get involved with lost or stolen property.
see http://support.apple.com/kb/HT2526
However, I hope you IMMEDIATELY changed your AppleID password when you noticed the added email - the only way someone could do that is if they know both your AppleID primary email address AND your current password.

Can my Airport Express be used to extend the signal for an iPad2

I am using a Linksys wired router as the beginning of my home network. There is an ethernet cable running from it through a wall to the Xbox 360 and an Airport Express serving as the base for the wireless network. I have an iBook on the other side of the wall and about 10 feet and an iMac about 20 feet with one wall in between. These two have some fluctuation in their signal but only between 4 bars and 3. I just got an iPad 2 and it is causing me grief because it struggles to maintain a connection just another 10 feet from the iBook. If I put it next to the iMac when it has full 4 bars the iPad gets maybe 2. The iPad has full bars if next to the router. That kind of defeats the purpose of buying an iPad. So, my question is how to rearrange the network so the iPad is happy in the living room where I mostly use it. I had considered moving the iMac and using it as a base station to free the Airport Express for other duty but where I want to move it is further away from the living room. Right now the Airport is wired to the router. Is this necessary for it to be a part of the network? I know I can use it to get music from iTunes to speakers but would that placement also work as a wireless extender? Would just buying another router for the Xbox location and putting the Airport there also be a better solution?

ladybastet, let's clean up some terminology. You should designate only one router for your network. At present that is the Linksys. Your wireless access point is the Express, and it gets its network connection from the Linksys. Is that correct?
If I put it next to the iMac when it has full 4 bars the iPad gets maybe 2. The iPad has full bars if next to the router.
Now that you know your Linksys is the router, is the above correct? Unless the Linksys is also a wireless access point, the iPad's proximity to it will not matter. Only its proximity to the device creating the wireless network is a factor. In your case, I believe that is the Express.
There is an ethernet cable running from it through a wall to the Xbox 360 and an Airport Express serving as the base for the wireless network.
I'm not sure I understand. Is one Ethernet cable going to two places? What is it connected to, precisely?
Right now the Airport is wired to the router. Is this necessary for it to be a part of the network?
In the case of a wired router, yes.
I'm wondering if you have things configured properly, particularly if you have configured the iMac to share its network connection over AirPort. I'm even wondering if your iPad has unintentionally joined a neighbor's wireless network.
I had considered moving the iMac and using it as a base station to free the Airport Express for other duty but where I want to move it is further away from the living room.
Using the iMac to share a wired Ethernet connection to create its own wireless network is certainly possible, but it is less than ideal. For one, the iMac would have to be powered on all the time.
You do not need or want another router.
It is impossible for me to be certain of your network environment (meaning, the size and configuration of your home, the proximity of competing wireless networks, the number of network devices, and the potential for interference) but you might be better off replacing the wired Linksys router with an AirPort Extreme. That would give you the ability to create a "roaming network" or to use your Express to extend the Extreme's wireless network. I think this would be the easiest solution, but given the uncertainly of your description this expense may not be necessary.
Much of my confusion stems from your original question: "Can my Airport Express be used to extend the signal for an iPad2" - the quick answer is yes, but a prerequisite question is, "what signal?" The only "signal" I can determine that may be relevant is the one created by the Express. Once we have the terminology fixed, perhaps we can fix what's wrong with your network.

How can I create a scrolling effect where when the user scrolls down the image will blur out?

How can I create a scrolling effect where when the user scrolls down the image will blur out?

Hi there,
You can create a scroll motion where the image will fade out on scrolling, you need to use the Opacity tab under Scroll Effects Panel.
If you particularly need the image to be blur out, then you need to edit that image in any image editing program and make one copy of that image as blurred, then place both images (actual and blurred) on that page and use scroll motion or fade option to replace images.

If the machine was upgraded to Lion 10.7.x by the original owner then you bought an illegal license of Lion and also of any other applications that the seller said came pre-installed, this assumes the seller did not include original install media. In that case you need to contact the seller for the original install DVDs that came with the machine re-install up to Snow Leopard 10.6.8 and then purchase Mountain Lion ($20) and the applications you want or need. If the seller cannot come up with the original install discs then you can buy them from a nominal cost from AppleCare..
