- Quake lab’s fully-PDMS DNA microfluidic synthesizer (20-mer oligos) is highlighted; the 2000 Unger et al. paper specifies RTV-615 silicone as the elastomer, and all features can allegedly be replicated with “shrinky-dink” microfluidics, yet no DIY build has been reported.  
- Discussion of anti-technology terrorism: the Mexican group “Individualidades Tendiendo a lo Salvaje” (ITS) is mailing bombs to nanotech and AI researchers, prompting campus security alerts and a Nature news article (http://www.nature.com/news/2011/110822/full/476373a.html).  
- Debate on AI risk: participants argue that self-improving AI is unlikely to be an existential threat because any system capable of world-ending actions is already “you’re fucked anyway,” and genetic algorithms are noted for finding misleading shortcuts (local optima).  
- Critique of LessWrong / Eliezer Yudkowsky: channel members mock the “rationalist singularity” discourse, calling it a cult-like distraction from actually building technology.  
- Industrial control obsolescence: 3-D printers and other lab hardware still run Windows XP (or older), are Internet-visible, and require proprietary tweaks to function—cited as a barrier to open hardware adoption.  
- 3-D printer kinematics: Ultimaker’s stationary-motor, lightweight-gantry design is identified as an effective way to reduce moving mass compared with the MakerBot Thing-O-Matic.  
- Cost anomaly noted: tungsten-carbide rods are reportedly one-fifth the price of equivalent stainless-steel rods, raising questions about supply-chain pricing.  
- Open-source CAD workflow: participants search for a Python wrapper around OpenSCAD that can be swapped with pythonOCC (candidates: cadmium, pyopenscad, openscadpy).  
- Reddit thread (http://www.reddit.com/r/science/comments/kil43/stand_up_against_the_antitechnology_terrorists/) is shared as a rallying point against anti-technology violence.
