- Cello, a Verilog-to-transcriptional-logic compiler for programming bacterial cells, was highlighted via a Hacker News discussion (https://news.ycombinator.com/item?id=11426957).  
- “Implantuino,” an implantable Arduino-compatible board for biohacking and body-area networks, was introduced (http://littlebirdelectronics.com.au/pages/introducing-implantuino).  
- Participants debated the prevalence of “consciousness/identity” misconceptions in mainstream transhumanist discourse, referencing a Reddit thread on mind-upload feasibility (https://www.reddit.com/r/Futurology/comments/4dfstn/mind_transfer_to_a_computer_could_be_possible_by/).  
- Dream-recall enhancement was discussed; pasky asked for substances that improve immediate post-sleep dream retention, noting current recall of only one dream every 1–2 weeks.  
- Bitcoin adoption anecdotes: nmz787_i paid for raw milk/cream with BTC, observing a ~15× higher fee yet sub-2-minute confirmation; pasky routinely buys Club-Mate/coffee with BTC in Prague.  
- SHA-1 collision economics were reviewed: cost to break is now ~US$75 k, and git’s GPG-signed commits do not protect against SHA-1 collisions on tree or blob objects (citing IACR ePrint 2015/967).  
- nmz787_i ordered a 2-layer PCB from OSH Park (13-day turnaround) and planned to experiment with a laser-etcher for photoresist exposure on copper-clad boards.
