# Key Ideas from #hplusroadmap IRC Discussion (Nov 27, 2014)

• Participants debated anonymous communication networks, analyzing Tor source code, mix networks, and high-latency systems like Pynchon Gate, with particular focus on different approaches to defeating timing attacks.

• A novel sensory augmentation device was proposed that would convert sound via Fourier transform into scaled-down physical vibrations worn on the arm, potentially helping both hearing people perceive out-of-range frequencies and partially restore hearing functionality for deaf people.

• Document organization systems were discussed, comparing tagging versus filename-based approaches for academic papers, with Recoll being recommended over Tracker (metatracker) due to Tracker's tendency to corrupt indexes after a month or two.

• Marvin Minsky's "Society of Mind" framework was debated, with some participants viewing it as "mostly useless from a practical standpoint" while others defended it as "highly how-oriented" and "a good descriptive framework" despite not being constructivist.

• Cambrian Genomics Inc. was noted to have raised nearly $10 million in funding in November 2014, with Anselm Levskaya involved, representing significant investment in genomics technology.

• A Bitcoin development pull request (#5048) was mentioned regarding an "addrindex" branch that optimizes retrieval of unspent outputs for any address, requiring approximately 37GB on mainnet, highlighting ongoing technical improvements to cryptocurrency infrastructure.
