Do apps go out of date if not used

I have set up volume purchasing on another education account. If i buy 20 apps and only use 11 on ipads do the other 9 go out of date/use after a certain time?

Apps don't go out of date like milk, but they may wind up missing updates unless auto-update is on or you have them in iTunes and update them manually. Not something to worry about.

How do I find out what features are not useful in my Classifier?

How do I find out what features are not useful in my Classifier? I am trying to trim down the number of features to speed up the training of my data, I have about 3700 features. I have found the Filter Based Feature Selection Module and have not been successful
in using it. I have looked through all the examples and have not been able to find any examples using the module. Will the Filter Based Feature Selection Module help me to trim features. If so how do I use it?

One way to do this would be is to use a random forest classifier. Feature/variable importance can be obtained relatively easily with random forests.
Here is how you may do it in R.
> install.packages('randomForest') #install randomForest package in R if it is not already there
> library(randomForest) # reference the library
> data(mtcars) # load motor cars data that ships with
#train a random forest
> mtcars.rf <- randomForest(mpg ~ ., data=mtcars, ntree=1000,keep.forest=FALSE, importance=TRUE)
> importance(mtcars.rf)
> importance(mtcars.rf)
#You will see an output like below
%IncMSE IncNodePurity
cyl 16.168645 169.96741
disp 18.672188 260.08722

# or plot the importance as follows
> varImpPlot(mtcars.rf)
What this tells you is how important predictors/features/variables like horsepower(hp), weight(wt), no. of cylinders (cyl) is in predicting miles per gallon (mpg).
If you are wondering how the data looks like. Try this
head(mtcars) # gives first few lines of the data set.
mpg cyl disp  hp drat   wt ...
Mazda RX4     21.0   6  160 110 3.90 2.62 ...

WebI:Creating a minus query from data providers not using the same universe

Hi there. A client of ours wishes to use Combined Query on multiple universes in the same WebI report. So far, I have heard it is not feasible in WebI. I know it is possible in DeskI. Even the sub-query option is limited to just one universe in WebI. So, I am stuck.
Is there a workaround to creating a minus query from data providers not using the same universe in WebI?

Hello Amit,
what are the Datasources ? Usually when you create a Sub Query you can choose a seperate Universe.
Maybe if you only see one Universe you only have the rights for this Universe ?!.
Regards
-Seb.

Out-of-date flagging not visible in package list?

In the old website design packages flagged as out-of-date were marked by a different color in the package list. This is not so anymore. How come? It was very useful.

Out-of-date package not been updated in almost a year

The question I have is: what should I do when I see a package that has not been updated in almost a year (after its flag-out-of-date)? I can't seem to find any info on how such a situation is handled. I can't reflag and sending an email to the maintainer seems intrusive and/or rude. There may be an underlying reason to not upgrade, or the flag was lost in time and forgotten.
The package I have in mind is opencl-headers. It got stuck on v1.1, and never updated to v1.2, and now still not to v2.0. There is an AUR package for the 1.2 headers, but that just seems silly to have around.
Thanks for any input!

I see, there is a backstory to all this. It seems though momentum was lost when ocl-icd devs did not respond to the email requesting info. The last commit to their repo was for 2.0 support, back in 2013. It seems abandoned since then, maybe a new spark of activity will come when a new OpenCL spec comes out.
The current situation is quite terrible really: libcl in the repos is from the NVIDIA package, so this means a hard dependency on a vendor not willing to follow the latest version of the spec. Way back when it was probably a sane choice, but now, as the email linnked by Allan shows, the situation is different.
Either choice, be it ocl-icd or Khronos, will improve the situation (OpenCL version and license-wise). Currently ocl-icd has one advantage (detailed in the POCL developer docs): choosing the icd at runtime.
As any CUDA or AMDAPP or Intel OpenCL package will include their libOpenCL, and it can be selected by LD_LIBRARY_PATH if required, I hope a sane libOpenCL package will soon make it into the repo.
As for backward compatibility: I believe the headers are backwards compatible, and it is up to the applications to verify the device they want to use supports the functionality they use. As for forward compatibility: if one solution fails and an alternative is better: just replace the package providing the ICD library by a better one.
Note that both the OpenCL headers and the ICD (libOpenCL) are designed to be platform-agnostic and should in principle work with all versions of the spec and devices, limited only by the device capabilities as reported through OpenCL functions. Currently, libcl and the old opencl-headers version is the limiting factor, which is Terrible®, given the (open source) alternatives.

App download and up dates are not longer working

Since two days the up date and download of apps is not longer working on my iPad

SELECT from SQL (Sql Manager) gives f.ex. "2010-11-27 00:00:00
Similar SELECT from the old ACCDB, linked to a MDB (query in ACCDB) gives "27-11-2010"
Similar select in new ACCDB, linked to SQL (query in ACCDB) gives "2010-11-27 00:00:00"
In linked table in new ACCDB the date is "2010-11-27 00:00:00"
In linked table in old ACCDB the date is "27-11-2010"
In form in new ACCDB is date seen as "2011-11-27 00:00:00"
When I do a AddNew (by VBA-code) the field change into "16-02-2011" and error while trying to update (wrong date format, I guess)
The update in this case is done by f.ex. doing a "DoCmd.GoToRecord , , acPrevious", which gives error code 2105 "You can't go to the specified record."
Another way that worked before is to go to another record by using a value from a Find-Record-form and do a "DoCmd.FindRecord <newrecordname>". This gives error 3146 "ODBC--call failed. [Microsoft][ODBC SQL Server Driver][SQL Server]Conversion failed
when converting date and/or time from character string. (#241)". Other functions (filling in other values in the form, based on a chosen name f.ex. is working, - but the record is never written to the Table).
In form in old ACCDB the date is seen as "27-11-2010"
When I do a AddNew (by VBA-code) the field change into "16-02-2011" and update and everytrhing is fine
Another way (than the AddNew) the date is created/changed is by using VBA "[datefield] = Date". The datefield is set to f.ex. "16-02-2011" (where old value could be "2010-11-27 00:00:00"), - and the same problems as described above is present.
Only way to "escape" is to click the ESC-key, to cancel all changes of the record in focus.
I hope this clarify, and I am at your disposal for further investigations any time ;-) almost 24/7, sigh...

Have you tried giving your iPad a reset? Hold down the sleep and home keys, past when you see the red power down slider and until you see the silver apple. let it reboot and try again.

Cost of App came out of bank account, not gift card...!?

Hey,
I recently redeemed my £70 Mac Apps gift card. I then downloaded Pages and Numbers. However, only the cost of ONE of them has come off my gift card account. I think the other has been charged to by bank account.
Anyone know how I can pay for the second one via gift card instead or is it too late? Hope I can because I'm totally skint!
Thanks!

Keep in mind, if the total cost of the apps purchased from the App Store exceeds the balance available from the redeemed card, the difference is then charged against your bank account.
Remove bank account details so only the cost is deducted from the redeemed card.
Click Accunt right side of the App Store window under Quick Links.
Enter your Apple ID and password then click View Account.
From the Account Information window click Edit to the right of Payment Type.
Remove your bank account details by clicking None then click Done bottom right side of the window.
Now when you make purchases, the amount will be deducted only from the balance of the redeemed card.

Subversion plugins for eclipse are out of date or not working

I have tried to install both subclipse and subversive from AUR. None of them work with current version of eclipse. Subversive cannot be installed because of broken jar files. Subclipse is for an older version of eclipse.
I have tried to install using eclipse pluginmanager, but it is buggy. I preffer a proper arch package in order to know what is installed.

Post your comments in the AUR, against those packages. Better still, update them yourself, and send your PKGBUILDs to the maintainers.

Out of date email originally used for ID

Light years ago, I had an email address situated to my parents home where i originally set up my itunes for the first time. I must have changed my apple ID pretty soon after setting the original one up, but made purchases through that email address. I have recently upgraded my laptop as my acient one decided not to work properly. I managed to copy all my files safely over to my new laptop and itunes but my ipod wont sync with some items as they need authorisation for the purchases i made with the original email address.
I also tried to get help through one of the site topics by typing in my serial number on the back of my ipod mini. The only drop down menu i was given was for a ipod shuffle, but mine is an ipod mini and so it didnt match the serial number correctly. Please help me

Go to Settings>iTunes and App stores and sign out and sign back in with the new ID.
Note:
- Apps are locked to the account that purchased them.
- To update apps you have to sign into the account that purchased the apps. If you have apps that need updating purchased from more than one account you have to update them one at a time until the remaining apps were purchased from one account.

HT2105 I have an itunes gift card, then found out that I can not use it with my KOBO Ereader. I was wondering if I could let someone else in my family use the balance of my gift card? They have an IPad and they often use Itune Gift Cards to purchase mov

I was given an itunes gift card, then found out that my KOBO Ereader will not accept the itunes gift card. I now have this gift card with a balance on it and would like to give it to my brother (he has an IPAD and uses Itune gift cards all the time). If he was to use my gift card (with my password) would the movie or book that he purchase show up on his devise or would it show up on mine. Thanks for all the help

I'm not sure what you mean. Did you redeem the gift card to your iTunes Store account? If not, just give your brother the gift card and he can redeem it in his own iTunes Store account. If you did redeem the card, then there's no way to transfer the balance from your iTunes Store account to his. He'd have to use your iTunes Store account to make the purchases and sync to his devices.
Regards.

How come the MyHeritage app blacks out when I try to use photos in my photo album on my iPhone?

Since around July I was having fun using My-Heritage's Celebrity Look Alike and playing with my friends, I was able to access uploading pictures from my album. But this month whenever I try going to my album, it turns all white, then completely black. The only thing that works on that is "Take A Picture" option, the "Take From Album" does not. What's the problem here?
I've tried deleting the app a few times and getting it again but still have this problem.

If you updates to iOS 7, it may be a compatibility issue that needs attention from the app developer. See if there is an update for your app.

XL Reporter Parameter that returns all data if not used

Is there a way to use a parameter on a field, but if the user doesn't select a value, return all rows? I have a report that returns a bunch of data about items. I would like one report where if the use chooses to narrow it down to a specific item they can, but if they choose not to narrow it down, it would return all items. I can only get it to do one or the other, but not both in one report.
Thanks

I have a parameter setup for the ItemCode and I tried to assign it * for its default value, but it returns nothing. If I enter a valid item code it works, but it seems as if I put an * in, it looks specifically for that rather than treating it like a wildcard. If I remove the parameter and put the *, it returns all. I want the parameter available, but if they don't want to use it I would like to return all records.
