C++ on the Web: Let's have some serious fun.

" summary

Shows how to compile and run real C++ in browsers using Emscripten and the new WebAssembly MVP, with examples using SDL/OpenGL (Angry Bots) and libraries like Box2D. Explains toolchain pieces (Clang/LLVM backend, Firefox Ion JIT), why WebAssembly binaries are much smaller than asm.js, and concrete sandbox techniques such as reserving a 4 GB address space to avoid most bounds checks. Notes deterministic floating point, indirect-call tables, and that zero‑cost exceptions, threads and dynamic libraries are planned but not yet in the MVP.
