- A new NASA-funded study pegs the cost of building a lunar landing pad at ~$12 B, highlighting the infrastructure bottleneck for sustained lunar operations.  
- Android 11/12’s SELinux restrictions block execve() but Termux still functions, illustrating the ongoing cat-and-mouse game between open-source hackers and mobile OS lock-down.  
- The FBI is returning computers seized 10+ years ago, raising unresolved questions about the integrity of any cryptocurrency wallets that may have been stored on the devices.  
- Practical pharmacology: Vyvanse can be micro-dosed volumetrically, but dissolving the time-release capsule removes the pro-drug mechanism and risks overdose.  
- Nature paper “Dual use of artificial-intelligence-powered drug discovery” (2022) was highlighted as a concrete example of how open-source AI tools can be repurposed for both therapeutic and weaponized compounds.  
- Cosmic expansion urgency: quadratic (surface-area) vs cubic (volume) growth models for reachable matter were debated, with the conclusion that accelerating cosmic expansion may permanently strand galaxies beyond the future light-cone.  
- Starseed launcher: a 1,000 km electrostatic accelerator could launch 0.3 c nanoprobes to nearby stars within decades, bypassing the need for new physics or megastructure-scale fusion drives.  
- Interstellar propulsion hierarchy: near-term Teller-Ulam “Ripple-X” nuclear drives are engineering problems, while attometer-scale black-hole rockets and self-replicating probes require speculative physics and materials science.  
- Black-hole rocket calculations: a 1,000-year-lifetime micro-singularity (Schwarzschild radius ~10⁻¹⁸ m) would emit 47 GeV gamma photons at 0.1 Mt s⁻¹ but would mass ~10⁶ t and demand impossible confinement and fuel-feed systems.  
- Penrose ergosphere maneuver: theoretical propulsion scheme where pellets or laser beams extract rotational energy from a rotating black hole via blueshift, returning momentum to the spacecraft—an extreme Oberth-like maneuver distinct from Hawking-radiation thrust.
