Is a universal web bytecode worth the trouble creating it? Is LLVM the solution? Which is better at running native code in the browser: Mozilla asm.js or Google PNaCl? This article contains opinions expressed on the web on these issues.
Beside C/C++, Google Native Client has added support for runtimes such as Mono, and a richer set of Pepper interfaces: accelerated 3D, full-screen, File IO, debugging, and others. New languages -Lua, TCL, OCaml- are being ported, and several major producers have ported their game engines or their games to NaCl.
Google Native Client has been included in Chrome 14 Beta, on its way to become a technology supported in production.
About a year after it’s original announcement, Google released a new version of the Native Client (NaCl) SDK, which allows the safe execution of native code from a web browser. It is unclear though, if this ambitious project will be making it to production, or have the fate of other projects like Wave or Gears.
