- A Wyoming legislative committee held a hearing on compelled disclosure of private cryptographic keys; Bryan Bishop posted a full transcript of the testimony at diyhpl.us/diyhpluswiki/transcripts/wyoming-select-committee/private-key-disclosure-buchanan/.

- A new study reported that fecal microbiota transplants from young mice to old mice reversed multiple biomarkers of aging, including improved cognition and gut integrity (sciencedaily.com, May 2022).

- Discussion of low-cost sensory-substitution hardware: lidar-equipped gloves and “whisker”-like tactile feedback points mounted on the face to give spatial awareness to visually-impaired users.

- Regulatory burden for medical-device classification was identified as the primary barrier preventing rapid deployment of open-source assistive technologies.

- Preference expressed for “simple, direct transformations” that let the human brain do high-level interpretation rather than complex embedded AI.

- Critique of existing haptic devices that use weighted motors: they suffer from low bandwidth, poor frequency response, and spin-up latency that degrades tactile realism.

- Proposal to replace motors with high-frequency acoustic drivers or resonators to achieve sub-millisecond latency and richer tactile spectra while avoiding unwanted low-frequency artifacts.

- Brief aside on the theoretical danger hash functions pose to backward-traveling time travelers, framed as part of a speculative “Timeline Anti-tampering Agency” concept.
