- A pay-walled IEEE paper (ID 4107565) was successfully retrieved via paperbot and mirrored at http://diyhpl.us/~bryan/papers2/paperbot/dd97fe11501cbc6357c4229d0492a2a7.pdf; Sci-Hub (http://sci-hub.org/) was endorsed as a fallback for bypassing journal paywalls.  
- Two additional PubMed articles (PMIDs 8011619 and 11573348) were mirrored by paperbot, illustrating the channel’s routine practice of archiving biomedical literature for open access.  
- Participants expressed skepticism about the oManual/Dozuki format promoted at the first Open Source Hardware Documentation Jam (NYC, 26–28 Apr 2013), arguing that its emphasis on “visual richness” undermines rigorous technical documentation standards.  
- When asked for Linux-compatible spatial-modeling software, brlcad was recommended over FreeCAD for its superior solid-geometry capabilities, despite a steeper learning curve.  
- A technical question was raised about whether the photon energies typically used in protein crystallography could destabilize nascent protein crystals, highlighting concerns over experimental parameters in structural biology.  
- bkero evaluated Protocase Designer, a domain-specific CAD tool for custom electronic enclosures, as a potentially useful addition to the open-source hardware toolchain.
