# Key Points from IRC Log

• A discussion about audio processing technology took place, with suggestions that neural networks could be useful for WAV to MIDI transcription, contrasting with an alternative approach of OCRing musical scores to MIDI.

• Kanzure shared a detailed bill of materials (BOM) spreadsheet for an ultrasound device project, which included components like accelerometers and gyroscopes for 3D alignment in augmented reality applications.

• Several participants discussed component selection for the ultrasound device, with suggestions that some parts (like the piezo transistor) were overpriced and could be replaced with more cost-effective alternatives.

• Kanzure shared multiple research papers on brain imaging and neural mapping techniques, including diffusion tractography analysis software, optogenetic stimulation combined with fMRI, and automated 3D cell segmentation frameworks.

• A paper on "The ethics of exponential life extension through brain preservation" was shared, along with research on viral vectors (lentivirus vs. adeno-associated virus) for gene delivery to different cell types in primate brains.

• There was a discussion about knowledge management systems, with kanzure expressing frustration that tag-based organization doesn't effectively compress knowledge or track "what people know" versus "what they should know."

• A reference was made to Galatea, an interactive fiction system that uses conversation commands like "ask about" and "tell about" to steer dialogue and track previously discussed topics.
