# Summary of IRC Log (October 23, 2009)

• Discussion about SKDB (open-source hardware/component database) focused on whether it could solve equations with parameters, with specific examples like metal extrusion formulas and yield stress calculations.

• Technical implementation details for SKDB were discussed, including the use of Python templates for equations with variables, configuration using YAML files, and a proposed distribution model similar to GitHub where users could fork and modify packages.

• Several standardized specifications for laboratory equipment were shared, including ANSI/SBS standards for microplate dimensions (footprints, heights, flanges, and well positions).

• A conversation about manufacturing techniques touched on challenges with machining pure aluminum and questions about how curved components were manufactured before CNC machines existed.

• Resources were shared about PCR purification protocols, with concerns raised about whether ethanol would destroy DNA and comments that PCR consistency is a significant challenge.

• The group discussed website architecture for SKDB, debating wiki functionality, user editing permissions, and how to handle package maintenance across different distributions of parts.

• Links to component specifications were shared, including LEGO grammar files, screw data, and supplemental units for the SKDB system.
