* Accept control commands via USB.

* Commands start with '!' and end with '.'
* Commands have three parts: action, pin, value: !AAPPVV.

* E.g. '!01p101.' is DigitalWrite, Pin1, value = 1

* Note: This is currently *very* crude. Much improvement could be made.
* I think the use of strncpy is eating a lot of memory. Refactor?

How to install iTunes 12 on Linux Mint 18 with working Store
View iTunes12-Wine-Ubuntu.txt
Trying to run iTunes with Wine, i faced various problems. Here is a working solution how to install iTunes on Debian-based systems (in my case Linux Mint 18.1) - with support for the iTunes Store. Warning: Syncing i-devices is still not possible.
When installing it with the playonlinux-"iTunes 12"-script, log in into the Store was not possible in my case. Wine showed the follwing error when trying to log in: SecurityContext failed with error 0x80090304
1. Install current Wine version (2.0.1) directly from the winehq repository
wget -nc https://dl.winehq.org/wine-builds/Release.key
sudo apt-key add Release.key
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main'
sudo apt-get update
sudo apt-get install --install-recommends winehq-stable
wine --version

Clone MiFare cards using chinesse UUID writable cards
View gist:ef6172da915a1b0803d41465b924d92a

libnfc supports UUID writable cards and even has some dedicated tools for them.

However it doesn't work with some of the cards found on eBay that are even simpler to use. Sector 0 is unlocked and can be written without any additional commands. libnfc requires a small patch to get it working.

Following has been tested under ArchLinux with modified libnfc 1.5.1, mfoc 0.10.2 and a SCL3711 dongle.

Patch & recompile libnfc

The patch is fairly simple, open libnfc-1.5.1/utils/nfc-mfclassic.c and comment 2 lines (it was lines 384 and 385 for me):
