• ResearchGate paper on “Anti-Aging Potentials of Methylene Blue for Human Skin Longevity” was shared as a possible topical longevity intervention, prompting tongue-in-cheek remarks about its dye properties turning skin denim-blue.

• Concern was voiced about the Internet Archive’s willingness (or lack thereof) to resist censorship requests, highlighting the fragility of long-term open-access preservation.

• A participant reported that a newly fabricated PCB worked on the first attempt—an outcome described as unusually rare even for “dead-simple” hardware security module boards, illustrating the iterative pain typical in open-hardware development.

• The exchange underscores the community’s dual focus on cutting-edge biohacks (methylene blue for skin aging) and pragmatic engineering realities (PCB iteration cycles).
