- Vinay Gupta and Marcin Jakubowski were interviewed on video about open-source hardware and global resilience; the clip was shared at http://www.globalswadeshi.net/video/2097821:Video:672.  
- A collection of pipe-specification documents and manufacturing references was posted, including zipped CAD data (http://heybryan.org/books/Manufacturing/pipes.zip) and a gizmology.net primer on pipe sizing.  
- Discussion of “compatibility checking” for modular systems contrasted simple geometric fit with deeper finite-element or SPICE-style analysis to predict leaks, explosions, or electrical failure when mismatched ports are connected.  
- The 1960s “bond-graph” formalism (H. M. Paynter) was highlighted as a unified, acausal modeling language for energy transactions across mechanical, hydraulic, and electrical domains; links to tutorials, software, and key journals were provided.  
- CAEX (IEC PAS 62424) and AutomationML were introduced as XML schemas for describing plant topologies and component interfaces, enabling data exchange between process-engineering and control-engineering tools.  
- A pointer to Eagle Genomics (http://www.eaglegenomics.com/) announced an open-source bioinformatics consultancy hiring remote developers.  
- Genehacker reported receiving initial RepRap parts (corner bracket and bed holder) and shared photos on Facebook, marking incremental progress in the community’s distributed-manufacturing efforts.  
- Papers on evolutionary algorithms for catalog design and the “resource-based paradigm” for configuring technical systems from modular components were uploaded to the channel’s book repository.
