overlay one pdf or ps file on top of another

 https://stackoverflow.com/questions/501723/overlay-one-pdf-or-ps-file-on-top-of-another

You can do this with pdf files using the command line tool pdftk using the stamp or background option.

e.g.

$ pdftk file1.pdf background file2.pdf output combinedfile.pdf

This will only work with a one-page background file. If you have multiple pages, you can use the multibackground command instead.

 https://superuser.com/questions/1429042/drive-not-listed-under-windows-10-indexing-options-and-so-not-selectable-for-in

• Suspecting the drive was not being properly recognized as fixed, I checked the indexing locations again under Indexing Options, recalling that I kept seeing a folder displayed with a long ID string, and a tooltip informing me that that particular location was unavailable. I never assumed this to be a problem since I also have USB drives plugged in/out sometimes:

• PROBLEM FIX: to set the drive to be seen by windows as permanently fixed follow Microsoft's own guide here: https://support.microsoft.com/en-us/help/3083627/internal-sata-drives-show-up-as-removeable-media

• If for whatever reason the command mentioned in the MS guide doesn't work follow these steps below

  1. open Registry Editor in administrator mode
  2. browse registry folders to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\Parameters\Device
  3. add a new "Multi String Value" called "TreatAsInternalPort" and list the bus number for the drive in question:

4. it should look like this once you are done: 

5. reboot and check Indexing Options again, you should now see your drive on the selection list.
