# Key Points from #hplusroadmap IRC Discussion

• A programmable self-folding origami robot sheet was shared, demonstrating advances in materials technology that can transform from 2D to 3D structures autonomously.

• Bryan Bishop presented on "Downloadable Hardware" at SciPy 2010, discussing pythonOCC and open manufacturing concepts, highlighting the intersection of software and physical fabrication.

• Current 3D printing technology was criticized for producing fragile parts "as strong as eggshells" despite using commercial SLS machines, indicating significant limitations in additive manufacturing.

• Research on DIY bio communities revealed most participants have technical degrees or college education, with unpublished survey data confirming this demographic trend.

• A distinction emerged between citizen science (focused on simple data collection) and DIY bio (requiring specialized technical knowledge), with citizen science potentially serving as an entry point to more advanced DIY communities.

• A 2002 research paper on genetically modified Streptococcus for dental health was discussed, noting only three test subjects received the modified bacteria, raising questions about the feasibility of DIY genetic modification.

• Nepomuk (KDE semantic desktop framework) was discussed as a tool for adding arbitrary folksonomy tags to music files, with Bangarang mentioned as having better integration than Amarok.
