- A DNA-based rewritable data-storage scheme was proposed that uses UV-C light as a low-resolution “erase head” to reset long stretches of pyrimidine dimers back to normal bases (0 → 0) and caged photolyase enzymes plus blue/violet light as a high-resolution “write head” to turn individual dimers back into intact bases (0 → 1), achieving bit-level control below the diffraction limit of light.  
- Participants debated the practicality of reading such a DNA tape, suggesting electric nanopores or Raman scattering on the same photolyases as possible non-destructive read mechanisms.  
- The wavelength-mismatch problem (UV/VIS ≫ molecular scale) was explicitly addressed: UV-C resets whole sectors, while nanoscale caged photolyases supply the sub-wavelength write resolution.  
- A side discussion on OpenSCAD noted that its built-in language is considered poor; practitioners typically generate OpenSCAD code from higher-level languages or libraries (e.g., a Clojure library mentioned).  
- DOJ action against a CoinJoin mixer developer/operator prompted questions about personal legal exposure for merely studying or running JoinMarket; advice included notarizing research notes and logs as a protective measure.  
- Transcripts and links from the Stanford Blockchain Conference 2020 (83 964 words total) were collected and published at diyhpl.us/wiki/transcripts/stanford-blockchain-conference/2020/.  
- Haskell build troubleshooting: GHC 8.6.5 resolved dependency issues, but older GHC versions failed on the -Wcompat flag; workaround was to remove -Werror from the implicit.cabal file.
