- A GitHub project titled “don’t-hold-your-breath” (https://github.com/kieranabrennan/dont-hold-your-breath) was shared, likely related to breath-control or apnea monitoring tools.  
- Participants compared CPAP machines with custom-fitted mandibular advancement devices (MADs) for treating sleep apnea; MADs are molded by dentists or can potentially be DIY-formed from polycaprolactone heated to 60 °C.  
- Concerns were raised about CPAP reliability—specifically, the fear that a device failure could lead to suffocation—while others noted CPAPs feel unnatural and are often removed during sleep.  
- Practical sleep-position advice emerged: side-sleeping reduces apnea events, and one user finds prone sleeping with the head rotated ~60° on a pillow or arms to be optimal for falling asleep.  
- A Yahoo Tech article (https://tech.yahoo.com/gaming/articles/chinese-brain-computer-interface-user-163148465.html) was circulated, highlighting recent advances in Chinese brain-computer interface gaming applications.  
- An 1883 public-domain book, “A Popular History of the United States” (https://ia601304.us.archive.org/35/items/popularhistoryof01kaem/popularhistoryof01kaem.pdf), was linked, possibly for historical context on technological progress narratives.
