# Key Points from IRC Log

• A paper on gravitomagnetic and acceleration fields around rotating superconductors was shared, discussing a theoretical propulsion system using a superconducting solenoid with a superconducting disk on top that could potentially create thrust without propellant, though this remains untested and controversial.

• Anders Sandberg publicly acknowledged using Modafinil in a blog post linked to Times Online, generating discussion about cognitive enhancement practices among transhumanists.

• Several open-source modular construction systems were mentioned, including Utilihab, Makerbeam, Contraptor, and OpenStructures, highlighting the growing interest in modular design frameworks.

• A discussion about "Transhuman Olympics" emerged as a potential project for Humanity+, where gene enhancement and other augmentation technologies could be showcased in athletic competition before such approaches become potentially regulated.

• A finger-mounted accelerometer system for typing was shared, capable of 200 symbols per minute with 52 total symbols, potentially achieving 80 words per minute with one hand, representing an alternative input method.

• The memory software Anki (a Supermemo clone) was discussed as an effective tool for language learning, based on psychological research about spaced repetition that has been largely ignored by mainstream education.

• Resources for legal document templates were discussed, with caution expressed about the reliability of "legal depot" websites that may be out of date regarding federal and state laws.
