• A video interview featuring Vinay Gupta & Marcin was shared, likely discussing open hardware or resilient community technologies (http://www.globalswadeshi.net/video/2097821:Video:672).

• Several resources on pipe specifications and standards were shared, including technical documentation on pipe dimensions and manufacturing (http://www.indpipe.com/product.asp, http://heybryan.org/books/Manufacturing/pipes.zip, http://www.gizmology.net/pipe.htm).

• Discussion of international electrical plug standards and adapters, with links to diagrams and historical standardization efforts (http://en.wikipedia.org/wiki/Domestic_AC_power_plugs_and_sockets, http://www.iec.ch/zone/plugsocket/ps_history.htm).

• A job opportunity was shared for Eagle Genomics, an F/OSS bioinformatics consulting company that allows telecommuting (http://www.eaglegenomics.com/).

• Detailed discussion about compatibility checking between ports using both geometrical analysis and FEA (Finite Element Analysis) methods, exploring how to ensure components can properly connect and function together.

• Resources on bond graphs were shared, which are a notational modeling system for capturing power/energy transactions between elements in mechanical systems (http://www.ece.arizona.edu/~cellier/bg.html).

• Discussion of CAEX (Computer Aided Engineering Exchange) and AutomationML, XML-based standards for representing plant topologies and object hierarchies in engineering (http://www.automationml.org/).

• A paper was shared on "Why mechanical design cannot be like VLSI design" examining fundamental differences between electronic and mechanical design paradigms.

• Resources on using evolutionary algorithms for catalog design were shared, exploring how to optimize component selection and configuration.
