A free cartoon browser game about how the internet really works: lay fiber and subsea cables, peer at IXPs, bill on the 95th percentile and survive backhoes, sharks and route leaks on your way to Tier 1.
A star delta has been computed for 61,707 of 62,629 tracked repositories in this period, and only those can be ranked in it.
A repository missing here has not been measured far enough back yet. That does not mean it did not move.
Star counts measured between 17:21 and 02:36 (BKK).

Describe any machine in one line. Claude builds a photoreal, physics based, interactive simulation of it in one HTML file, plus the film to post it. An open source Claude Code skill.
One open-source modeler for structures, heat and fluids, built from scratch in pure Rust: parametric part in, verified results out. Automatic all-hex and tet meshing, our own nonlinear implicit and explicit FEA, heat transfer and lattice Boltzmann CFD — every result checked against theory. For engineers and AI agents alike. Free, forever.
