# Key Points from #hplusroadmap IRC Discussion (September 26, 2009)

• Kanzure demonstrated SKDB (skill/knowledge database), a Python implementation for modeling complex processes like making an apple pie, with resource allocation capabilities rather than building everything from scratch.

• Participants discussed reverse engineering efforts between Solidworks and OpenCascade, noting structural similarities in their code and sharing documentation of Solidworks' source structure.

• The conversation included technical debate about "Lorentz force" propulsion systems for spacecraft, examining how magnetic fields and current loops might create asymmetric force for propulsion.

• An interesting hypothesis was proposed that the technological singularity may have actually occurred in 1969, citing the microprocessor invention, internet beginnings, Engelbart's demo, UNIX, the moon landing, and cultural shifts.

• The group discussed retrograde satellite orbits, noting their increased fuel requirements (losing ~3000mph advantage by launching against Earth's rotation) and higher collision risks with standard-orbit satellites.

• Ed Boyden's work on "synthetic neurobiology" and optical control of neurons was referenced as a significant advancement in neuroscience.

• Resources shared included command set documentation for the FIALab Microsia 8 valve syringe pump and "1800 Mechanical Movements, Devices and Appliances" as a valuable mechanical design reference.
