# Summary of #hplusroadmap IRC Log (Nov 23, 2011)

* A brief discussion about microchimerism occurred, with user JayDugger expressing discomfort about the concept, comparing it unfavorably to symbiotic gut bacteria which "know their place."

* An Android application for controlling RepRap 3D printers via Bluetooth was shared, with links to both the Thingiverse page (http://www.thingiverse.com/thing:13506) and the GitHub repository (https://github.com/pipakin/Android-Bluetooth-Reprap).

* A user shared a link to Gregory Chaitin's website (http://cs.umaine.edu/~chaitin/), noting that the mathematician appeared to be interested in 3D printing technology.

* A tool called "getxbook" was shared (http://njw.me.uk/software/getxbook/), which appears to be software for retrieving books from online sources.

* The conversation demonstrated ongoing interest in maker technologies, particularly 3D printing, which was a recurring theme in the transhumanist community during this period.
