- A discussion of space-based manufacturing highlighted containerless melting, molecular-beam epitaxy, and the claim that lunar glass (low water content) could be 100× stronger than terrestrial fiberglass.  
- Centrifugal “artificial gravity” was proposed as a way to combine the benefits of zero-g and Earth gravity for long-duration habitats.  
- Sleep-typing experiments were reported: users captured semi-coherent dream text such as “reveal the underlying onion derivatives of the situation” and “the nuclei are on their way,” with no automated mis-alignment correction yet implemented.  
- A survey of nootropic advice recommended starting with single compounds (e.g., theanine + caffeine, piracetam) and microdosing to reduce side-effects; methylphenidate was cited as producing strong agency but “not worth it” side-effects.  
- Links shared for further reading included the 2016 Slate Star Codex nootropics survey results and Gwern’s comprehensive Nootropics page.  
- Slack vs. IRC debate covered onboarding ease, open-source alternatives (Mattermost, Matrix), and the need for distributed, encrypted chat tools.  
- Frank Herbert’s concept of towing freshwater bags behind ships was revived as a cheaper alternative to desalination.  
- A brief aside noted the lack of consumer Raman spectrometers for on-the-spot drug testing, with reagent kits offered as a stopgap.
