# Summary of RepRap Project Git Migration Discussion

• Developers were working to migrate the RepRap open-source 3D printer project from SVN to Git, facing challenges with the repository's unusually large 2GB size, which was noted as inefficient for Git since it contained binary files rather than primarily text files.

• The team established a comprehensive repository infrastructure with both read-only access (git:// protocol) and write access (git+ssh://), implementing a web interface through cgit at https://secure.diyhpl.us/cgit/reprap/ while planning to mirror to GitHub.

• Technical discussions focused on preserving commit history and author information during migration, configuring proper permissions, and resolving issues with Git's "receive.denyNonFastForwards" setting that initially prevented necessary force pushes.

• Participants debated version control alternatives, with some advocating for Fossil SCM (which combines version control with wiki and bug tracking) while others preferred "bugs everywhere" which stores bug state within the distributed version control system.

• Kanzure mentioned working on an open-source CAD kernel in Python with STEP export capabilities, discussing implementation challenges and explaining why existing open-source CAD kernels (BRL-CAD and OpenCASCADE) were insufficient for mechanical component design.

• The group critically analyzed a controversial paper about red rain cells that allegedly reproduce at 121°C without DNA, identifying methodological flaws including failure to account for pressure effects during autoclaving and questionable claims about extraterrestrial origins.

• A novel funding model was proposed where Kanzure would invest $50 in anyone writing a grant proposal, doubling the amount for subsequent successful projects as a low-risk approach to supporting innovation.

• Participants mentioned DARPA's interest in funding SKDB (kanzure's project) for developing "complex, realistic cyber-electro-mechanical war fighting machines" that would require multi-terabyte repositories for simulation results.
