- Discussion of using antitrust law against the MPEG-LA patent pool as a strategy to counter restrictive CRISPR-Cas9 licensing, citing the 1999 Yale Journal on Regulation paper “Patent pools and the antitrust dilemma.”  
- A proposal for “nanny grey goo” – molecular-nanotech-based, law-enforcement-oriented AI that would police arbitrary physical regions by enforcing programmable spatial rules, framed as an alternative to MIRI-style friendly-AI research.  
- Exchange on the feasibility of DNA-targeted bioweapons for political assassination, referencing the 2012 Atlantic article “Hacking the President’s DNA” and noting that the U.S. State Department has covertly collected heads-of-state DNA samples (per WikiLeaks cables).  
- Technical note that commercial CD/DVD glass masters are produced photolithographically and then electroformed; suggestion that obsolete “laser beam recorders” might be acquired cheaply for hobbyist nanofabrication.  
- Observation that induction lighting systems can achieve 100 000-hour lifetimes, outperforming early LEDs, and discussion of why electrodeless discharge lamps fell out of favor despite analytical advantages.  
- Search for open machine-readable atomic-spectra databases: frustration over NASA’s discontinued ADC archives and NIST ASD’s reduced functionality, followed by discovery of a 1993 NIST ASD subset and a German mirror (http://www.maa.clell.de/Cat/Vol4/6069/).  
- Recommendation of #linuxcnc IRC channel for CNC machining questions and mention of Autodesk Pier 9’s 09:00 opening hours as a practical constraint for hardware hackers.
