I am on Ubuntu 14.04, XDN-project Cryptonote-Universal-Pool, and nodeJS 0.10.48.  I've done a lot of code updates on my version now because I see that the block format of XDN has changed twice in the last year.  The first change was with the inclusion of Merged Mining in November 2016, the second change was in January 2017 with a block size update and miner update (XMR RingCT code added for XMR merged mining).  I will send you a message on Ryver thank you.
