- DIY weapons improvisation was illustrated with Atlantic photo-essay on Libyan rebels fabricating mines and bombs, prompting comparisons to sci-fi insurgency tropes.  
- CAD workflow debate: Blender deemed unsuitable for precision design; Modelica-integrated tools (Pro/E, jModelica) recommended for simulating plumbing, pressure, and valves.  
- Open-manufacturing leadership changed hands when kanzure was granted ownership of the Google Group “openmanufacturing.”  
- Links to open-source CAD resources: Salome platform Windows builds and Open CASCADE documentation were posted for download.
