Windows Store in-app purchase error - your purchase couldn't be completed

Issue

Can't complete an in-app purchase in Windows Store on a Windows 8.1 tablet. The in-app purchase was for Island Tribe game (to upgrade it to the full version).

After clicking buy and entering the password, following error would show up:

Your purchase couldn't be completed

Your purchase couldn't be completed
Please try again later.

Trying again later didn't really help... The whole thing was making a certain 6 year old quite upset, so a swift resolution was required!

Automatically split and straighten scanned photos

I recently had a task to scan large number of old photos using a flatbed scanner. Scanning photos one by one would be terribly inefficient as I could normally fit 4 - 5 photos on the scanner. Scanning multiple photos on one page was obviously much faster, but it left me with another task of cropping and straightening photos afterwards. Again, doing this manually would consume too much time so I looked for some sort of automated solution.
