- A modular, snap-fit laptop concept (Modulus) was shared as an example of eco-friendly, user-serviceable hardware design that could reduce e-waste and empower DIY repair.  
- Participants discussed the SKDB project: a nascent open-source database of technical devices and components, with kanzure committing YAML files listing laboratory and electronic equipment to the repository.  
- genehacker explored using homing pigeons as a low-tech, high-security file-transfer channel, weighing the risk of rural hunters against surveillance resistance.  
- The group debated the merits and pitfalls of obsessive life-logging and rigid scheduling; fenn demonstrated a minimalist timestamp-plus-activity text format, while others warned that org-mode and similar tools can become counter-productive.  
- GNU Units was highlighted as an under-appreciated command-line tool for precise unit conversion, with a 4,700-line data file covering everything from slugs to solar constants.  
- A call was made to replace traditional printed steam tables and other engineering look-ups with programmatic, formula-driven alternatives, ideally integrated into SKDB.  
- Links to open educational resources included the Harvard Healthy Sleep site, the SleepDex encyclopedia, and two DefCon 17 slide decks (parts 1 & 2) on building a DIY sleep lab and EEG recording.  
- bkero shared a $250 electric-bike build and pointed to the $672 “Forkenswift” DIY electric car as evidence of ultra-low-cost EV experimentation.  
- ybit demonstrated rapid Wikipedia list extraction via DBpedia SPARQL queries, suggesting it as a faster route than bulk Wikipedia dumps for populating SKDB parts lists.  
- The channel’s culture of radical openness was underscored by critiques of DRM-locked textbooks and the invocation of Stallman’s “Right to Read” essay as required reading.
