- “Space fog” was proposed as a massively-parallel micro-reaction or storage medium: millimetre-scale sterile metal rods with water or emulsifier droplets held by surface tension, positioned and separated by laser light in zero-g; participants debated evaporation, humidity, temperature uniformity, retrieval and power issues, and suggested switching to non-volatile droplet chemistries or encapsulating membranes.  
- A PEDOT–CNT coated electrode paper was retrieved (Journal of Neural Engineering 12 016014) showing retinal neurons can be stimulated at unusually low voltage and charge density, relevant to next-gen neural interfaces.  
- Discussion of sub-vocal EMG and EEG “mind-typing” explored correlating imagined audio with neural or muscular signals; skepticism was voiced about classic EEG “brain-wave” approaches, while others suggested dense multi-channel RF or network-analyzer-based acquisition to capture higher-frequency neural signatures.  
- Brillouin’s kT ln 2 minimum energy per bit flip was cited, followed by a critique of “entropy-as-order” interpretations and the claim that the Second Law positively selects processes (including life and technology) that maximize entropy production.  
- A pointer to http://booksc.org/ was shared as a searchable repository for academic books and papers.  
- Linus Torvalds’ 2000 LWN post defending kernel-debugging difficulty was linked, alongside an anecdote that OpenBSD’s kgdb includes a hangman game playable after kernel panics.  
- Practical Linux debugging tips included a one-liner for logging GDB backtraces to a file and reminders that forgetting return statements for std::vector or std::string can cause segfaults.  
- Emacs vs. vi/IDE debate reiterated the preference for composable command-line tools over monolithic IDEs, with mention of Emacs “evil mode” for vi keybindings.
