How to connect an iOS device to your computer via a SOCKS proxy

Say you're running a virtual machine on your work computer. Say this machine, for whatever reason, can only connect to the internet over NAT - as in, it does not get it's own IP address. Say this VM is running a webserver, and you need a device outside of your computer to connect to it.

If only there was a way to get your work computer to 'share' it's network, so that you could get at that VM… Here's how you do it!

For all instructions, I assume your work computer is a mac

Get your computer's IP address:

We now have reached a corner regarding the development of webruby.Emscripten is now switching to a LLVM-based backend, which eventually will replace the old JS-based backend. However, a bug in clang prevents us to use the new le32-unknown-nacl triple in LLVM/emscripten, it also prevents us from using the new LLVM-based backend of emscripten.

A fix has been developed for LLVM to solve this problem, but as of today, it's neither in the PNaCl fork of clang, nor emscripten-fastcomp-clang. So this prevents us from switching to the latest version of emscripten.

In a meantime, an attempt to fix this problem at mruby side was also rejected, since this would complicate mruby a lot for a small corner case.

We could maintain
