# Key Points from #hplusroadmap IRC Discussions

• Participants extensively worked on SKDB (Skill and Knowledge Database), an open-source project for managing technical knowledge, focusing on web interfaces, git repository management, and package organization for physical objects.

• The group discussed self-replicating systems, debating whether allowing mutations would be beneficial or dangerous, with some members proposing a "replicator club" focused on building such systems as primarily an engineering challenge.

• There was significant criticism of Singularity University as an expensive ($30k for 9 weeks) "money-making scheme" that attracts notable speakers but fails to deliver substantive value, with specific concern about researcher Ralph Merkle's involvement.

• Participants analyzed advanced rocket propulsion technologies, particularly aerospike engines and reciprocating free piston pumps developed by Lawrence Livermore National Laboratory that could enable low-cost single-stage-to-orbit vehicles.

• The conversation explored nitrogenated carbon nanotubes (N-CNTs) as superior catalysts for hydrogen peroxide decomposition, with references to scientific papers documenting this capability.

• Members discussed DIY approaches to technology, including genetic testing methods (real-time PCR) and the democratization of manufacturing technology, noting the high cost barriers for components like SMT reel feeders ($500-1000) despite their seemingly simple design.
