# Key Points from #hplusroadmap IRC Discussions

• Cryonics infrastructure was discussed, including the $27 million Timeship project, the need for monitoring systems to detect fatal events for people living alone, and research into independent liquid nitrogen production for cryonics organizations.

• Participants explored ultra-high density living environments inspired by Kowloon Walled City (which reached 3.5 million people per square mile), discussing how master planning and proper infrastructure could improve such environments.

• Technical discussions covered pneumatic infrastructure systems, including vacuum-based waste collection networks and proposed positive pressure pneumatic capsule delivery systems for goods transportation in dense urban areas.

• Biohacking topics included a participant experimenting with attaching small magnets to fingernails to simulate magnetic implants before committing to actual implantation, demonstrating the DIY experimentation ethos in the community.

• Technical resources were shared, including Berkeley lectures on distributed machine learning systems and tools for MCMC (Markov Chain Monte Carlo) sampling and software-defined radio applications using GNU Radio with RTLSDR.

• The community discussed personal health metrics, including resting heart rates among participants, and shared scientific resources such as microscope slides of Einstein's brain on display at the Mütter Museum.

• Participants reflected on the challenges of maintaining personal software projects versus contributing to larger open-source initiatives, noting the trade-off between independence and the social coordination challenges of collaborative work.
