# Key Points from #hplusroadmap IRC Discussion

• Developers were building a web interface for SKDB (Sketchup Database), a distributed repository for parts and designs aimed at automating the building process, with features including file editing, commit history, and MIME type handling.

• The group compared 3D printing technologies, discussing the tradeoffs between MakerBot ($700) and RepRap/RepStrap systems, with one participant sharing their experience testing PLA (polylactic acid) properties at high temperatures (255°C).

• OpenSCAD was highlighted as a promising parametric 3D modeling tool with its own programming language for creating fabrication-ready models.

• Members shared impressive 3D fractal visualization resources, specifically the Mandelbulb project (http://www.skytopia.com/project/fractal/mandelbulb.html), demonstrating interest in advanced computational geometry.

• The community discussed creative hardware hacking possibilities, including the potential conversion of a 7.5-ton overhead crane at a hackerspace into a large-scale CNC machine.

• Participants explored information filtering challenges, suggesting grammar-based systems or relational word networks as potential solutions for managing content relevance in RSS feeds.

• The group mentioned upcoming transhumanist events including an "H+ Summit" in California (with online streaming) and a potential local "SKDB installation fest" meetup.
