• Datahand ergonomic keyboard patents have expired, making open-source clones viable; members debate whether the steep learning curve is justified by potential speed gains for high-WPM typists.  
• Experiments in EMG-based silent input—using throat/face electrodes, non-audible murmur microphones, and even toe-muscle EMG—are being explored as covert typing methods, with social acceptability compared to early Bluetooth headsets.  
• Google Glass backlash is framed as primarily a reaction to covert photography and poor UI, not the concept of face-worn sensors; the “GlassHoles” meme is cited as evidence of public sensitivity.  
• Ralph Merkle’s original motivation for public-key “puzzles” was to re-establish secure communication after a computer and its terminal had been fully compromised and re-sealed, leading to the insight that confusion for an eavesdropper must grow faster than for legitimate parties.  
• Zero-knowledge SNARKs enable logarithmic- or constant-size proofs that a program was executed faithfully without re-execution; “bootstrapping” (inspired by fully homomorphic encryption) allows nesting proofs so each step only verifies a short proof of the previous step.  
• Bitcoin scaling discussions dismiss simple block-size increases or “just use a DHT” as inadequate; multiple BIPs (100, 101, 102, 105, etc.) have been exhaustively reviewed, and the group emphasizes that consensus rules, not literal transaction storage, are the core concern.  
• Greg Maxwell’s informal write-up “Simple Verifiable Execution” (people.xiph.org/~greg/simple_verifyable_execution.txt) is shared as a readable introduction to SNARK concepts.  
• Project Cybersyn (1973 Chilean cybernetic economic management system) is cited as an alternative to markets as a computation device for resource allocation.  
• DIY DNA synthesizer project using an inkjet-based microarray approach is mentioned as an open-hardware effort, though no single lead builder is identified.  
• Longaccess shutdown illustrates archival fragility, underscoring ongoing concerns about long-term data preservation for personal and scientific records.
