- GitHub’s “Arctic Code Vault” project will archive every active public repository plus selected dormant ones on film reels stored in a Svalbard mine, accompanied by a “Tech Tree” that explains QR decoding, file formats, and metadata so future humans can reconstruct the code.  
- Discussion framed John Carmack’s ability to experiment with AI at home as a side-effect of nuclear technology having been regulated into near-oblivion, while general-purpose computing remains comparatively free.  
- Participants argued that the poor state of manufacturing automation—not a lack of good CAD files—blocks rapid hardware iteration, citing the lone developer behind freesteel.co.uk who writes most real-world machine-tool paths.  
- AMD’s 16-core Ryzen 9 3950X (7 nm, 105 W) was praised as proof that chiplet architectures can scale core counts without exploding power budgets; stacking dies with micro-fluidic cooling was proposed as the next step.  
- Intel’s Optane 3D-XPoint (phase-change memory) was dissected: it behaves like memristors, offers DRAM-slot persistence, but needs proprietary chipsets, costs more per GB than used DDR4, and suffers higher write latency.  
- Cache-size stagnation was questioned; L3 caches have grown ~10× in a decade yet SRAM economics and the von Neumann bottleneck still limit performance, prompting calls for memristor-based L4/L5 caches.  
- Twist Bioscience’s IPO was noted as a milestone for commercial synthetic-biology DNA synthesis.  
- A Science editorial marking the “unwanted anniversary” of CRISPR-baby news was shared, underscoring ongoing ethical and regulatory debates in germline engineering.
