- The channel dissected IRS rules for open-source projects seeking 501(c)(3) status, concluding that “releasing code” alone is insufficient; successful exemptions (Apache, NumFocus) must re-frame the work as scientific research, education, or charity for the underprivileged.  
- A live build log documented the first working SWIG wrapper for the open-source OpenNURBS C++ geometry kernel, showing how to eliminate ~20 undefined-symbol errors by ignoring missing member functions, stripping OpenGL/X11 dependencies, and producing a loadable _opennurbs.so module.  
- Participants compared the Rhino3D fork of OpenNURBS—which removes intersection and Boolean operations—with the BRL-CAD fork that retains them, and noted that SWIG’s %ignore directive must precede class definitions to suppress unimplemented methods.  
- A proposal to NASA Ames was circulated to fund an open-source “lunar hackerbase,” arguing that the maker/hacker community could supply low-cost R&D to help NASA hit a <$2 B/year lunar outpost budget; skepticism centered on whether a Moon base is the most efficient path to open-source aerospace tech.  
- MakerBeam, a miniature T-slot aluminum kit (€50 starter pack with 50 beams and 60 brackets), was highlighted as a rapid-prototyping resource for hardware builds.  
- nmz787 announced new part-time employment as a Focused Ion Beam (FIB) operator, foreshadowing upcoming nanofabrication projects relevant to the channel.
