• The channel approved a plan to index the entire #hplusroadmap IRC archive with Elasticsearch, aiming to create a searchable, open corpus of transhumanist and biohacker discourse.

• Participants debated the theoretical limits of computation, citing Wolpert’s work and the paper “Extending Landauer's Bound from Bit Erasure to Arbitrary Computation” (arXiv:1508.05319), which explores halting oracles and distributions over computable functions.

• Recent neural-network research was shared, including “Learning universal computation with spikes” (arXiv:1505.07866) and “Recurrent network models for human dynamics” (arXiv:1508.00271), alongside Elon Musk and Sam Altman’s arguments for open, democratized AI as a safeguard against runaway superintelligence.

• Optical metasurfaces and wavefront-shaping techniques were dissected: nanoscale antenna arrays for flat optics, ultrasound-tagged optical phase conjugation for imaging deep inside scattering tissue, and photoacoustic tomography (PAT) achieving ~7 cm depth at ~1/200 depth-to-resolution ratio with potential contrast-agent enhancements.

• Hobbyist feasibility calculations showed that ~200 automotive batteries could power a ~1 MW laser for 4–9 s, with solar trickle-charging and transformer stages, while global continuous power (~16 TW) was estimated as the theoretical upper bound for a planet-scale laser.

• DIY threads covered sourcing an ultrasonic scaler for epoxy removal, selecting the motorized Derminator derma-roller for hair-regrowth experiments, and building passive-radar rigs with synchronized RTL-SDR dongles.

• Side experiments included RF eavesdropping on USB keyboards using RTL-SDR/USRP gear and 3-D LED tree mapping via structure-from-motion photogrammetry.

• Structural-biology discussion centered on the newly published 3.6 Å structure of the Cav1.1 voltage-gated calcium channel complex, with brainstorming on real-time imaging of its voltage-dependent conformations via flash-freezing, epoxy embedding, and super-resolution optics.

• A brief technical note proposed using Kolmogorov-complexity-like metrics to quantify motor plans by the bit-length of reachable poses, while acknowledging the limitation of ignoring real-time sensory feedback in motor coordination.
