# Key Points from IRC Discussion

• The Emotiv EPOC headset was discussed, with kanzure examining its technical aspects including the "EmoEngine" software, electrode design (wet electrodes requiring saline), and licensing model that restricts access to raw EEG data behind a $1000 paywall.

• Technical analysis of the EPOC headset software revealed machine learning components including Principal Component Analysis (PCA), Gaussian training, and MANOVA statistical methods for processing brain signals.

• Several biohacking and synthetic biology initiatives were mentioned, including BioBricks (http://bbf.openwetware.org/), with discussion about NSF grants in cyberinfrastructure being notably filled with buzzwords.

• Bluetooth hacking resources were shared via http://www.hackfromacave.com/projects.html, potentially relevant for DIY brain-computer interface development.

• Augmented cognition concepts were discussed, including a "wearable remembrance agent" (http://www.bradleyrhodes.com/Papers/wear-ra-personaltech/) and sentiment analysis for social media (http://stackoverflow.com/questions/573768/sentiment-analysis-for-twitter-in-python).

• The conversation touched on Plan 9's "everything is a filesystem" philosophy in relation to the EPOC headset's web server functionality, showing interest in novel interface paradigms.
