- A free residual-gas analyzer (mass spectrometer) was offered on Freecycle, but the filament is open; replacement filaments cost ~$485, prompting discussion of DIY tungsten-wire repairs and the need for a high-vacuum system.  
- The group debated how to evolve planar linkage mechanisms with genetic algorithms without the search collapsing into trivial circular shapes, and whether diversity-of-solution could serve as a useful fitness metric.  
- Links and tutorials for mechanical-kinematic design were shared: commercial software “ARTAS” for linkage synthesis, Wikipedia’s mechanical-linkage page, and Blender rigging guides for Theo Jansen–style walking machines.  
- A Japanese sea-slug, *Elysia chlorotica*, was highlighted for having acquired algal photosynthesis genes—an example of natural horizontal gene transfer that could inspire synthetic-biology fuel or energy projects.  
- A spectacular 538-ft² ant-colony excavation video was circulated; participants mused on digitally scanning the entire structure to create an “ant Blue-Brain” model and extract distributed-system design patterns for multi-agent software.  
- Open-source visualization and simulation tools were recommended: VTK, OpenFOAM, FreeFEM3D, Mayavi, and Blender’s inverse-kinematics add-ons; a 566 MB apt-get list was provided for lab machines.  
- Discussion of closed-source physics sandbox “RigidChips” led to posting of its bundled VB6 example code and debate over whether visible code constitutes open source.  
- Freecycle anecdotes included bulk-pickup offers of G3 Macs, NetVista boxes, and a North-Texas hoard of AT terminals, illustrating the community’s hardware-scavenging culture.  
- Cloud-computing blog posts predicting the demise of sysadmin jobs were critiqued; participants argued that automation merely shifts human effort rather than eliminating it.  
- A half-serious proposal to hijack the Super Bowl broadcast and transmit a “neo-Golden Record” of transhumanist memes (de Grey, Kurzweil, Gershenfeld, etc.) was floated as a viral-mindshare thought experiment.
