- A new parser for ImplicitCAD is being debugged; the maintainer reports improved error detection and is cleaning up user-submitted scripts to restore compilability.  
- nmz787 contrasts ImplicitCAD with BRL-CAD, noting that a one-day ImplicitCAD script was far simpler to write than the equivalent in BRL-CAD, suggesting the latter’s interface still lacks ergonomic scripting support.  
- Switzerland has banned laser pointers nationwide; the channel discusses potential penalties and the practical impact on traveling technologists who rely on them for presentations.  
- A Twitter thread is shared describing an early AR prototype that projected images directly onto the retina with “magic-like” fidelity, but required a room-scale computer array and immobilized the user; the company pivoted to conventional smart glasses after failing to miniaturize the optics.  
- jrayhawk references NVIDIA’s near-eye light-field display prototypes and explains that true AR passthrough would demand front-mounted light-field cameras to capture and re-render the external world in real time.  
- A Science paper on “Ultralarge elastic deformation of nanoscale diamond” sparks a cryonics brainstorming session: docl proposes coating diamond microstructures with metal to exploit reversible deformation for rapid, magnetically-triggered cooling cycles analogous to the magnetocaloric effect.  
- The proposed cryo-cooling scheme encloses the patient in an ice bath inside a large electromagnet; ramping the field deforms the diamond, and abruptly switching it off releases stored elastic energy as ultrasound, accelerating heat removal.
