# Key Points from IRC Discussions on Transhumanism and Open Technology

• DIY transhumanism (DIYh+) faces practical challenges in hackerspaces, including a shortage of biology-focused members and reluctance to invest in expensive equipment like $4-5k photolithography machines without guaranteed outcomes.

• Participants discussed computational recipe representation through RxOL format, which formalizes cooking recipes in computer-readable notation to enable automated processing and filtering based on properties like complexity or energy density.

• Open hardware projects were a central topic, including CNC machine designs, welding techniques that utilize different electrical currents (DC Negative, DC Positive, and AC) for various metals, and an open-source gel electrophoresis box for DIY biology.

• Software tools for technical drawing and modeling were evaluated, including PyX, SVGFig for Python-based SVG manipulation, and NURBS libraries for curve modeling, alongside discussions of file format compatibility issues between CAD formats (DWG, DXF, IGES, STEP).

• The SKDB (Standard Kit of Design Bits) project was discussed in relation to integrating different unit conversion systems for scientific applications, combining sympy.physics.units, sympycore, and quantities.Quantity.

• Cross-platform development technologies were debated, including PyJS/Pyjamas as a Python-to-JavaScript converter, and specialized tools like PyFeyn (a Python library for drawing Feynman diagrams in physics) with its XML specification "feynML."
