How can I tell if one of my iBooks has an update available?

I was listening to a podcast where the author of a particular iBook, which I have purchased, stated that there was an updated version available.
My questions are:
Is there some way to know that there is an update to an iBook I have purchased and have installed on my iPad? Maybe someting like the 'Updates' section of the iTunes and App Store?
Is there some way to tell what version of an iBook I currently have installed?
Regards,
John

Open Termninal.app (which is in /Applications/Utilities/), and type the following (and Return key) in the Terminal window:
last
this will show recent logins in reverse time order (from new to old). If the output has too many lines, then
last | less
you can use SPACE and 'b' keys to go down/up screen. Hit 'q' to quit less. Or
last > logins.txt
then a file 'logins.txt' will be created in your Home folder, and you can open it with your favorite text editor (e.g., TextEdit.app).

I have lots of duplicate songs in ITunes. How can I tell which ones were purchased vs ripped?

I am trying to delete duplicate songs in iTunes library. How can I tell which ones were iTunes purchases and which ones I ripped from CD's.

If you turn on the Kind column your purchases will read Purchased AAC audio file or Protected AAC audio file.
BTW I've written a script called DeDuper which can help remove unwanted duplicates. See this thread for background.

Here are the specs and configurable options for your HP Pavilion p7-1380t Desktop Computer. Here are the specs for it's H-Joshua-H61-uATX (Joshua) motherboard. According to the motherboard specs, this system has 4 USB 2.0 ports on the back as shown below;
(#1) USB 2.0 x 4
Typically, USB 3.0 port are blue and have a stylized "SS" symbol near by. There does appear to be a USB 3.0 header on the motherboard, which could be used for front or rear ports.

When a contact has multiple numbers, how can I tell which one called me?

For example, if a single contact entry has a "home" number and a "mobile" number, there seems to be no intuitive way to tell which one called me from the iOS 7 phone app--only the contact name is listed on the Recents screen, and the info button for the call shows all the numbers for that contact.
I've done extensive searching, and though I found some people asking the same question, I couldn't find any answers! I could wait and examine my phone bill statement, but I don't think it shows the incoming number... I figure there must be a way, because clearly my phone knows the specific number!

When I look at calls in my Recents list, there are two lines. The top line is the contact name, the second line is the listing from my contacts that indicates the label for the number the call came from. If that is not enough, then you can tap on the at the end of the listing which brings you to the individual contact. The number you received the call from will be in a different color than the other numbers. In mine it is in blue. This is just like the information provided in the earlier part of this thread.

How can I tell that a default numeric format has been applied to a numeric limit step?

I am working on generating custom HTML code for our test systems in order to reduce the 'footprint' of the standard HTML entries for numeric limits, multiple-numeric limit steps etc....
For a Numeric Limit step, I can set the Numeric Format via the 'Limits' tab and select the pulldown arrow to select any format. Does TestStand actually save this information with the step so I could possibly use this later? I ask this because my modifications are within the 'ModifyReportEntry' Callback. When I am modifying the code to generate new HTML within this callback, I have no idea if the developer has selected a Numeric Format for a given step OR simply left it as DEFAULT.
To make matters more confusing, here is some more information....
When I pause the execution in the callback I notice the following:
Case 1: User has selected a Numeric Format ( this example I will say 3 digits of precision ) %.3f. for a numeric limit step.
Parameters.Result.Limits.Low = 10.000
Parameters.Result.Limits.High = 20.000
Parameters.Result.Numeric = 15.657
Notice the numeric data is ALREADY formatted! Great, I can simply use this to generate my custom HTML table for the numeric limit step.
Case 2 : User has left the numeric format to <Default> for the step.
Parameters.Result.Limits.Low = 10
Paramters.Result.Limits.High = 20
Parameters.Result.Numeric = 15.65713515155
Numeric data is NOT formatted. I know that TestStand will apply the Default Numeric Format that is configured in the report options when it writes the report but since I am doing a custom report I am stuck.
My question is how can I possibly tell that the data has already been formatted by TestStand in the ModifyReportEntry callback? Is there some flag that I could check or anything?
I do notice that the Parameters.ReportEntry string contains TestStand's default HTML code for the step and this is already properly formatted.. so as a possible workaround I could 'pick out' the data from this string but this is slow and time consuming.
Thanks
PH

PH,
You can find out if the numeric format has changed using the TestStand API. I use the following statement in my step's post-expression to find out the numeric format that TestStand uses for the step.
Step.Limits.Low.NumericFormat
If the string returned is an empty string, then it is the default format, otherwise, it's the one specified in the string.
Hope this helps.

One or more cartidges appears to be damaged How can I tell which one?

I just had my 4 cartidges refilled at Cosco. Came home and installed them and get the One or more cartidges appears to be damaged message. Looked at the little example on the printer screen and it looked like it was telling me the Yellow was the one. Just bought a new yellow and still get the message. Does the printer tell you which cartridge is bad or is it just replace them all?

bnba,
Welcome to the HP Forum.
Commentary
This is a difficult question to ask of our Experts in that most of us would never suggest that you use refilled cartridges in your HP printer in the first place.
Long term, you might damage the printer using refilled ink cartridges. This is true for any brand printer in my opinion.
If the printer was inexpensive to begin with - well, little lost except the shame for the trash created when the printer must be replaced soonner rather than later.
If you paid good money for that printer - then you might consider the investment you have made thus far and decide whether refilled cartridges are worth the risk.
Short term -- you can run a diagnostic test on the printer and see if it can tell you what it thinks about the situation.
Most printers provide diagnositcs and testing under Settings or Tools on the Front Panel.

How can I tell if a non-destructive crop has been applied when opening an image?

I've wrapped my head around how to reclaim the stripped-out portion of an image that has been non-destructively cropped in CS6: click the image with the crop tool, or select Reveal All from the Image menu. Short of doing this every time I suspect that I may have cropped an image, is there anything in Photoshop's interface to tell me at a glance if the image has been non-destructively cropped? I guess I could check the document dimensions in the pop-up status display at the bottom of the window, but I'm looking for something more direct that doesn't make me search.

If you primarily edit files from a particular camera, then your idea to set the status box at the lower-left to show the image dimensions is a good one - just watch for dimensions that are not the norm.
You shouldn't have to set the readout to Document Dimensions more than once, though... Open one image, set that field to read Document Dimensions, then close the document and quit Photoshop gracefully. From now on it ought to read Dimensions when you open a new document.
I wasn't aware 10.8.1 was out.

How can I tell if an Object Input Stream has more objects to read?

I have a utility that I'm working on where objects are sent via the network as a complete file. I read the objects, update some, and send them back. I never know how many objects are in the file. I cache the file locally prior to performing this operation. It runs in a chron job.
Currently I am reading until I get an EOF exception. Is there a better way? I've tried available() but it is always returning me zero.
Thanks.
ST

The API says:
Any attempt to read object data which exceeds the
boundaries of the custom data written by the
corresponding writeObject method will cause an
OptionalDataException to be thrown with an eof field
value of true.
Hope this helpsThis doesn't help at all. It refers to what happens while you are reading a single object, not to what happens when you try to read a new object. You will not get this exception between objects.
If as I suspect you are reading from a socket you really have no choice but to try the read, maybe with a timeout. EOF is the only condition that can reliably indicate that there are no more objects in this stream.

How can i tell what computers are authorized with my itunes account?

My iTunes app tells me that I have 5 computers currently authorized with my account. How can I tell which ones they are??? I've checked all of my old desktops and laptops to deauthorize them but they indicate that they were never authorized. Confusing. Why go to the trouble managing how many are authorized if you don't provide a means to list them??? I realize that I can deauthorize them all (the only choice!) but, in doing so and reauthorizing the ones I need, does this mean that I lose the ability to access previously purchased music on them?? I must say that, for the ease of use of the Apple apps, I expected more. Thanks:-) !

You cannot. You can see the number of authorised machines.
Go to itunes Store, Select Account from Quick Links on the right.
If you already have 5 authorised but can't remember which the machines are you have the option of once every 90 days to deauthorize all comuters and then individually reauthorising the ones you want.
On each machine in iTunes Click Store > Authorise this computer

How can you tell which computer that is authorized as the master?

I have several computers that I have connected my iPhone to. How can I tell which computer I should connect to before updating the operating system? I don't want to loss data if I don't have to.

I am not that familiar with Apple and iTunes and was getting help from someone who said that I can plug my iPhone into my computers but that I would have to authorize the iPhone on each but the limit is 5.
This is not accurate.
You can authorize up to 5 computers with the same iTunes account. There is no device limit for the number of iPods, iPads, and iPhones that can be synced with the same iTunes library and iTunes account on the same computer.
An iPhone can be synced with an iTunes library on one computer only, and photos can be transferred from one computer only. When transferring iTunes content and photos from another computer, all iTunes content and photos transferred from a different computer will be erased from the iPhone first.
This is why I asked - you have connected your iPhone to each one of these computers for what?
I was not sure which computer I first used. Is there a simple way to check?
No, or I would have provided that with my first reply.
If you connect your iPhone to a "non-master" computer to install the update, you will be provided a warning.
How many computers are you talking about? If 5 or less, this should take you no more than 10 minutes to determine which computer you transferred music and photos from.

There are so many add-ons now that do the same thing, how can I tell the full features of an add-on compared to the others. I know I have way to many of the same and need to get rid of the unwanted ones?

can we get a side by side comparison of the add-ons. How can I tell Ive got 2 or even 3 add-ons that do the same thing? and how can I pick the best one for my needs so I can uninstall all the others?

I mutled through best I could but I know I still have duplicate apps, different names, but same functions. One last thing is why do I keep getting 2-3 times a day that firefox needs a major update? I let it go through its motions but then that same msg pops up again a few hours later

"Volume not found" I have 3 iphoto_libraries stored in a external disk, while the actual files are in other external disk. Ive moved together iphotolibraries and files but: HOW CAN I TELL THE LIBRARIES WHERE TO FIND THEM NOW?

I have three iphoto_libraries stored in a external disk PASSPORT (one for each trip imovie Im making -Ive managed this way the libraries so to not confuse the trips) while the actual files are in OTHER external disk LACIE. And everything was fine: imovie find each library, could work with it, or iphoto could edit the files.
But one day everything crashed at the same time: i opened iphoto to find 3 different scenarios:
1) iphoto_library GREECE was there, but not the albums i prepared. no events. when double click in any of them: "Volume not found"
2) iphoto_library ITALY was there, and the albums i prepared too, but empty.
in both cases I can only see the photos in 'photos' because 'events' shows some events with photo preview and some with no preview, just some kind of preset clipart palm tree, but if i enter the event, photos are there but again: when double click in any item: "Volume not found"
3) iphoto_library ISRAEL was there, the albums too, when double click in any of them: all OK
The 3 libraries was managed the same way. Meaning: Ive imported photos to iphoto from external disk LACIE in a iphotolibrary stored in another external disk PASSPORT. Also: I don't have unchecked the option "copy to file" or something like that. photos where moved, not copied. Also i have all the movie_libraries in the PASSPORT as well. What happened??
Solution? Nothing yet. Ive moved now all the photo folders from LACIE together in PASSPORT with the iphotolibraries but problem persist:
HOW CAN I TELL THE LIBRARIES WHERE TO LOOK FOR THE VOLUMES NOW?
"Volumes" are the original files aren't them?
Please help. this is so annoying to try and find in the forum, to tricky to explain
I have a Macbook pro retina Yosemite 10.10.1 / iphoto 9.6 (910-29)/ iMovie 10.0.6
THANK YOU
Vicky

The 3 libraries was managed the same way. Meaning: Ive imported photos to iphoto from external disk LACIE in a iphotolibrary stored in another external disk PASSPORT.
This is not clear, especially when you say
I don't have unchecked the option "copy to file" or something like that. photos where moved, not copied.
Especially as the message you're getting is typical of a library where the ' option "copy to file" or something like that' is unchecked.
So it's a simple question:
Are you these Managed or Referenced Libraries?
A Managed Library, is the default setting, and iPhoto copies files into the iPhoto Library when Importing. The files are then stored in the Library package
A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. (You unchecked the option to copy files into the Library on import) The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management.
