The floor is lava, trying to teach C++
summary
Two two‑day courses teach programmers from other languages a minimal, modern C++ workflow by building a small game that runs without no new or delete and forbids raw pointers; unexpected practical demands force inclusion of things originally avoided (inline/ODR, pragma once). Community polling yields thousands of Twitter replies and shows most “lava” lives in advanced, specialized corners. Material stresses useful tools (clang‑tidy, sanitizers, fmt), build/tooling practices, and concrete error causes so learners can compile, debug, and ship working code.
