Welcome to the RadixIndex Advent Calendar 2016! The calendar of this year has only 10 windows - but all of them will have some pleasant surprise to find. Come back to see the windows open daily between 15-24 December, as some of the presents will be good for a limited time only! Daily windows open at 00:01 Central European (Paris) time. Would you like to see some features added to RadixIndex - or even to this calendar? Your wishes are welcome either by email or by your comment to the dedicated December 2016 wishlist thread on our Facebook page.
