# Key Points from #hplusroadmap IRC Discussion

• Participants discussed pH electrode storage solutions, recommending a mixture of pH 4 buffer with potassium chloride and a biocide (sodium benzoate or sodium azide) to prevent mold growth during storage.

• A user sought help with the NEURON neural simulation engine to import the OpenWorm connectome onto an embedded device, aiming to create a robot with a worm brain that uses solar input and servos for motion.

• The conversation included detailed analysis of CAD software options, with Rhino 3D ($750, or $140 for students) highlighted as the industry leader for NURBS-based modeling, while FreeCAD, OpenSCAD, and ImplicitCAD were discussed as open-source alternatives.

• Technical limitations in open-source CAD were examined, particularly how McNeel (Rhino's creator) released OpenNURBS as open-source but withheld critical surface-surface intersection methods and proper testing frameworks, forcing projects like BRL-CAD to reimplement these features.

• Resources for learning Haskell were shared, including Stephen Diehl's comprehensive guide "What I Wish I Knew When Learning Haskell 2.2" (http://dev.stephendiehl.com/hask/).

• The Intel Edison was discussed as a compact computing platform (35.5 x 25 x 3.9 mm) featuring an Intel Atom SoC with 2 cores at 500 MHz, 1GB RAM, 4GB flash storage, and wireless capabilities for approximately $50.

• Participants debated applying AFL fuzzing (American Fuzzy Lop) security techniques to hardware interfaces like NFC and car door systems, suggesting potential for hardware security testing.
