• A Brazilian biohacker (luisjustin) described an under-funded but well-equipped lab in Brazil (~450 reagents, greenhouses, metallurgical/electronics workshops) and is seeking collaborators to repair a proprietary biochemical analyzer and launch open plant-biology projects.  
• The group discussed the difficulty of repairing proprietary lab equipment whose parts carry scraped manufacturer codes, highlighting the need for local electronics expertise or reverse-engineering skills.  
• Trail of Bits’ blog post on “Engineering Solutions to Hard Program Analysis Problems” was shared, underscoring ongoing interest in formal methods and security tooling within the community.  
• A Blockstream job posting for a protocol/security engineer was circulated, with community members noting skill-set overlaps and offering to answer questions about the role.  
• Pijul, a new version-control system claiming to fix Git’s three-way merge strategy, was debated as a promising alternative versus improving Git itself.  
• A paper titled “Who steers who steers? A note on identifying vulnerable moral propensities” was shared to frame AI safety as a problem of moral alignment rather than mere technical control.  
• Eliezer Yudkowsky’s recent AI-safety writing (now mostly on Facebook) was characterized as “world peace enforced by a benevolent dictator,” highlighting skepticism toward politics-based solutions.  
• Bram Cohen’s 2017 SF Bitcoin Meetup talk on Merkle Sets was referenced, tying Merkle-tree data structures to scalable, tamper-evident storage.  
• Git’s architectural flaws (immutable hash choice, 00000000 special-case hash, transport-specific manifests, lack of built-in symbolic checkouts) were dissected, with the observation that most users rely on centralized third-party services that bypass canonical Git tooling.
