- Apple Watch’s optical heart-rate sensor reportedly fails on tattooed skin; participants speculate whether darker natural skin tones or scar tissue from burn injuries would trigger the same problem, highlighting early limitations of consumer biosensors.  
- A Forbes article (http://www.forbes.com/sites/thomasbrewster/2015/04/17/hacker-tweets-about-hacking-plane-gets-computers-seized/) is shared, illustrating the real-world legal risks of publicly discussing potential aviation-system vulnerabilities.  
- The Selectron tube—an early 256-bit electrostatic memory device from the 1950s—is examined as historical inspiration for modern experiments; one participant proposes patterning a glass plate with charge to direct complementary DNA binding, merging vintage computing concepts with synthetic biology.  
- Discussion of intellectual-property constraints on hardware includes the Semiconductor Chip Protection Act of 1984 (SCPA), which grants copyright-like protection to integrated-circuit layouts while explicitly permitting reverse engineering under a “substantial similarity” test.  
- Microcode embedded in silicon is noted to be copyrightable, reinforcing the legal complexity surrounding open-source or emulated processor designs.
