- A 2015 Nature Nanotechnology paper (PMC4591029) on injectable, self-expanding neural mesh electronics was discussed; participants noted that the mesh does not fully unfold inside brain tissue but remains near the injection-needle diameter, relying on its spring tension to maintain intimate cellular contact (Fig. 4h).  
- The group briefly explored the idea of embedding miniature spectrometers in footwear for covert biochemical analysis, but dismissed it as impractical compared with simply carrying a handheld spectrometer.  
- Eudoxia reported learning Apache Spark and CUDA while experimenting with a concept for a new compile-to-CUDA programming language that would incorporate Rust’s type system for safer GPU programming.  
- Kanzure linked a Reddit thread on “whole-brain emulation philosophical conundrums,” criticizing it as an example of unproductive speculation in the transhumanist community.  
- A retro-styled Bluetooth mechanical keyboard disguised as an old typewriter (the “Penna”) was shared from Hacker News as an example of quirky consumer hardware.
