- The channel discussed BRL-CAD as a CAD tool for generating 3-D models; one participant exported a personal cross-section into an STL file containing 32 triangles and shared a screenshot at http://heybryan.org/shots/2008-12-15_brlcad.png, noting that Tcl/Tk interface is dated but that BRL-CAD can be scripted from the shell.

- Participants debated the absence of an “undo” function in BRL-CAD’s .g format, concluding that if every GUI action were logged as a scriptable command, replaying the log would provide version control.

- Social-network data mining was described: one member had written a Twitter bot that automatically friended friends-of-friends and introduced itself, and considered extending the idea to Facebook via an early “Facebook shell interface.”

- A University of Wollongong press release (http://www.eurekalert.org/pub_releases/2008-12/uow-ntc121508.php) about mining Facebook data for sociological research prompted privacy concerns, with one participant stating he would never have opened an account had he known the data would be harvested.

- The channel shared speculative futurist media, including the YTMND animation “thefutureofourworld” and a 750-million-year galaxy-collision timeline, alongside tongue-in-cheek discussion of Aubrey de Grey’s beard as a “longevity cocoon.”
