• IBM’s 1977 AUTOPASS paper is retrieved and analyzed as an early object-oriented, English-like language for automated mechanical assembly, highlighting its grammar, motion-planning hierarchy, and swept-volume collision detection as inspiration for modern CAD-to-assembly pipelines.  
• Participants propose Spatial Constraint Graphs (SCGs) to encode which parts block one another along mating directions, arguing that current Lego-style virtual assemblies lack geometric collision detection and that naive “add-in-order” sequences often yield impossible real-world builds.  
• The open-source SKDB project commits new code for UNC/UNF thread specifications, integrates uncertainty handling in its units module, and prototypes pyODE-based collision detection for B-rep models while debating GPU-accelerated alternatives.  
• A volume-based collision heuristic is implemented in SKDB (geom/geom.py::estimate_collision_existence) that flags interference when the summed volume of individual parts minus their Boolean union exceeds a tolerance, offering near-constant-time checks compared to the existing O(n²) BRepAlgoAPI_Common method.  
• A “uzbl + xpather” workflow is introduced for maintainable web-scraping: a headless WebKit browser lets users click on DOM elements to auto-generate XPath selectors, reducing scraper maintenance from hours to minutes when sites redesign.  
• The same click-to-select mechanism is extended to an annotation tool that feeds an external editor (e.g., Emacs) for margin notes while storing offline snapshots of web pages to survive future changes.  
• MakerBeam and Contraptor—open-source modular construction kits—are linked, though skepticism is voiced about MakerBeam’s $10k Kickstarter goal, and a 1952 blacksmithing handbook PDF is archived as historical fabrication knowledge.
