- High-G flight exposure in male fighter pilots shifts offspring sex ratio to ~60 % female / 40 % male when flying occurs 11 months before birth, according to a 2010 naval-aviation study shared in the channel.  
- Discussion of open-source cryptographic tooling included links to the secp256k1-zkp threshold-signature design doc, SLIP-0021 hierarchical key derivation, SLIP-0039 Shamir mnemonic sharing, and an in-browser JavaScript Shamir tool at passguardian.com.  
- A novel phased-array optics experiment was proposed: using an off-the-shelf LED monitor to photo-voltaically drive piezo-ceramic (PZT) mirror elements for sub-wavelength path-length control, with $10/kg PZT powder sourced from Alibaba.  
- Technical critique of the LED-driven piezo concept noted that visible-light photoelectric voltages (~4 V) are insufficient for the ±15 V required for micron-scale piezo travel; alternative electron-bombardment via CRT was suggested.  
- Channel members observed the global Cloudflare outage that day, highlighting risks of centralized infrastructure and noting downstream failures (e.g., ScienceDirect).  
- Additional links circulated: Black Python code formatter documentation, the original 1979 Shamir secret-sharing paper, and a transcript of Joost Jager’s 2019 Breaking Bitcoin talk on “hodl invoices.”
