# Key Points from IRC Log

• A paper on Borromean ring signatures for Bitcoin was shared (https://github.com/Blockstream/borromean_paper/raw/master/borromean_draft_0.01_58a5cbc.pdf), along with discussion about Bitcoin's blocksize limit and decentralization.

• Researchers discovered previously unknown lymphatic vessels in the central nervous system, potentially changing our understanding of the brain's relationship with the immune system, as detailed in a Nature paper (http://www.nature.com/nature/journal/vaop/ncurrent/full/nature14432.html).

• A Frontiers in Systems Neuroscience article was shared discussing brain-computer interfaces and their potential to expand beyond current limitations by creating brain-brain interfaces or connections to ectopic neural modules.

• Discussion of data recovery techniques included the practice of "platter swapping" - physically transferring hard drive platters to recover data from damaged drives, which is apparently a common procedure despite the precision required.

• Carbon nanotube memory (branded as "NRAM") is now being manufactured in fab plants, suggesting progress in this storage technology.

• Magic Leap shared a video demonstrating their augmented reality technology, though one participant expressed skepticism about AR implementations, noting that machine vision "sounds nice in theory but in practice I'd have to do all the coding anyway."

• The Open Hardware Summit 2015 in Philadelphia was mentioned as an upcoming event that some participants were planning to attend.
