Joe Kesselman, IBMer since before the IBMPC, software hacker since well before that, badly out of practice at hardware-level Unix admin but relearning it.
I was involved in a significant chunk of IBM's XML efforts (including serving on the W3C's DOM Working Group and being involved in the code which became Apache Xerces and Xalan); more recently I've had my fingers in Websphere Liberty and in some of the Watson Health projects.
If you websearch for "keshlam", you'll find everything else I've been involved in. About the only references that I know of which aren't me are "Kesh Lam" and Tempus Keshlam on TheManaWorld.
Current Pi project: A quick swing at getting the WiSH drivers (https://sourceforge.net/projects/wish
) running to control old an old X10 interface. Those were written for an earlier Linux, and there are still some edges that need to be hammered back into place before it'll work, but I've posted what I've done so far to its mailing list. If it doesn't work fairly quickly I may resort to one of the other solutions, but Wish has the advantage of being easy to control from the command line, which would make it easy to tie into HA-BRIDGE and integrate into SmartThings.
