- A 2.4 GB scrape of MatWeb materials‐property data (metals, ceramics, plastics, etc.) was compressed to 480 MB and posted at http://heybryan.org/~bbishop/docs/matweb.zip for open use.  
- NeuroCommons RDF dataset requirements were clarified: ~50 GB current, 300–400 GB projected; loading the SPARQL endpoint needs ~8 GB RAM, with download instructions at http://neurocommons.org/page/RDF_distribution.  
- Discussion of “passive” high-resolution brain-typing devices: Utopiah shared a comparison matrix of fMRI/EEG approaches at http://seedea.free.fr/wiki/pmwiki.php?n=Content.Concepttreefmri.  
- Wildcat-CAD (open-source parametric CAD) was mentioned; ybit reported no Linux release yet in SVN.  
- A major semiconductor-fab auction listing 50+ tools (Applied P5000 CVD, LAM etchers, KLA metrology, etc.) was linked at http://www.go-dove.com/auctions/AuctionDetail.asp?auctionID=11912 as a potential hacker source.  
- Debian’s Social Contract was cited as an example of governance documents emerging *after* a project already exists, debated in the context of defining “open” for open-manufacturing efforts.  
- SPI (Software in the Public Interest) was noted as a non-profit umbrella for open hardware/software projects.
