- FreeCAD 0.16 and BRL-CAD were discussed as complementary open-source tools for MEMS-scale CAD, with the suggestion that combining them could improve computational stability for micro-device design.  
- Early “digital organism” experiments—self-replicating machine-code programs competing for CPU cycles—were revisited, with links to the Wikipedia article on digital organisms and the Avida simulation platform.  
- A debate on “bio-radio” explored whether living cells could be engineered to fabricate functional RF circuits; Geobacter sulfurreducens “nanowires” (2015 mBio paper) were cited as evidence of biological metallic conductivity, while skeptics argued that GHz oscillators and low-loss centimetre-scale conductors remain incompatible with biological media.  
- The “High Frontier” board game was praised for embedding real research citations—superconductor solar sails, 1950s magnetohydrodynamic generators, etc.—within its speculative tech tree, serving as an educational resource for space-based transhumanist concepts.  
- A proximity-tracking proposal suggested using bladeRF SDR to spoof cellular towers and log nearby phones, aiming to build an “everyone-ever” contact database for epidemiological or social-graph research.  
- An optimization strategy for social discovery was outlined: use prior data to compute information-maximizing questions (e.g., stance on cryonics) to map and shift individuals’ positions in “idea space.”  
- Experimental support for quantised inertia in the EM-drive was shared via arXiv:1604.03449, alongside a Nature study on the diurnal water-ice cycle on comet 67P/Churyumov–Gerasimenko.  
- The concept of “ultraslow radio” (sub-Hertz signalling) was introduced, referencing a 2012 essay that notes the ancient Chinese text 春秋 effectively transmits at ~1 bit per day, though critics from bitcoin-wizards IRC argued that such links suffer from decoherence and oscillator drift unless all parties possess high-precision atomic clocks.
