# Key Points from #hplusroadmap IRC Log

- Discussion about personal knowledge management systems, with participants debating the merits of full-text indexing for personal digital archives versus using existing search tools like Google Books for retrieving personally relevant information.

- Critique of semantic wikis as requiring too much understanding of underlying ontologies, with the observation that most users will unintentionally misuse such systems, contrasting with the original wiki philosophy of minimizing markup and maximizing accessibility.

- Reference to amateur rocketry technology, with mention that "Black Rock Desert in Nevada is the only place in the country with an FAA waiver to shoot up 100,000 feet."

- Discussion of advanced materials including aerogel production techniques, noting that supercritical drying (used in aerogel manufacturing) is similar to processes used in decaffeinating coffee beans.

- Reference to SpaceX's office culture, mentioning "a full-size Iron Man statue standing proudly next to the cylon in the breakroom" and discussion of rocket design using "nomex-honeycomb fins."

- Link shared to research about potential differences between gravitational and inertial mass: http://www.technologyreview.com/blog/arxiv/25331/
