# Summary of IRC Log from #hplusroadmap (September 6, 2016)

• A reference for "balloon hashing" was added to the DIY H+ Wiki, with a link to a transcript from a July 2016 Bitcoin developers-miners meeting featuring Dan Boneh (http://diyhpl.us/diyhpluswiki/transcripts/2016-july-bitcoin-developers-miners-meeting/dan-boneh/).

• Discussion of open-ended evolution (OEE) in digital systems, with kanzure noting the problem of "complexity ceilings" in evolutionary simulators and suggesting "co-evolution of simulator and organisms" as a potential solution to overcome limits on novel phenotypes and biodiversity.

• Several academic papers were shared on artificial life and digital evolution, including "Does self-replication imply evolvability?", "Information-theoretic considerations concerning the origin of life", and "Different evolutionary paths to complexity for small and large populations of digital organisms."

• A collection of papers on "open-ended evolution" was shared from Tim Taylor's website (http://www.tim-taylor.com/oee2/ and http://www.tim-taylor.com/oee1/), discussing the theoretical frameworks for creating systems with continual evolutionary innovation.

• A link to DIY micro-survival gear and mobile shelters was shared (http://www.elkinsdiy.com/), featuring projects like a micro-airstream bike camper, showing practical applications of minimalist design principles.

• A mention of open-source hardware microfluidics work was made, linking to http://luis.labfab.cc/, which appears to be connected to Avida (an artificial life/digital evolution platform) development.

• A discussion about the EM Drive included a note that it would soon be tested in space, though participants questioned whether such testing was warranted.
