- A Danish firm’s claim to have 3-D-printer “malware” that fingerprints and blocks gun files is dismissed as technically futile because toy guns, slingshots, and even fire-truck parts share the same geometric signatures, highlighting the impossibility of reliable content-based DRM for additive manufacturing.  
- Carbon-fiber 3-D weaving is illustrated by a Lexus LFA factory video showing robotic A-pillar construction, while RepRap experiments remain limited to XY-plane fiber embedding, underscoring the gap between industrial and open-source composite printing.  
- Aubrey de Grey’s new adjunct professorship at Moscow’s MIPT sparks discussion of his 1990s Silicon Valley wealth and the independence it grants his longevity-research agenda.  
- The 2009 Schmidt & Lipson “Science” paper on symbolic regression—where genetic programming rediscovered physical laws from raw data—is resurfaced as a landmark example of automated scientific discovery.  
- Entry-level and advanced SDR hardware are catalogued: RTL-SDR dongles for receive-only, $400 BladeRF and $800 USRP for transmit, with Casper boards for phased-array experiments; BladeRF’s user-reprogrammable FPGA and a $600 “extra-large FPGA” variant are highlighted.  
- A crowdsourced satellite-dish timeshare project is proposed: purchase a 3–5-foot ex-military dish on eBay and let remote users schedule sky-scanning sessions via software.  
- The BioBricks registry is criticized as a “mostly-non-working SDK” lacking a community of “actual DNA hackers”; participants argue that only independent, non-academic biohackers can iterate the parts into a functional toolkit, drawing parallels to early script-kiddie culture in software.  
- Synthetic-biology reading list: Greg Egan’s “Chaff,” Peter Watts’ Rifters trilogy, Paul McAuley’s Quiet War series, and Greg Bear’s Blood Music (with advice to stop one-third of the way through) are recommended as hard-biotech inspiration.
