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

1. Get your computer's IP address:

Simple demonstrations of putting AVR microcontrollers to sleep in power-down mode,
which results in minimum current.  Coded with Arduino IDE version 1.0.4 (and with
the Arduino-Tiny core for the ATtiny MCUs, http://code.google.com/p/arduino-tiny/)

For ATmega328P, ~0.1µA.
For ATtinyX5 revisions that implement software BOD disable, ~0.1µA,
for ATtinyX5 revisions that don't, ~20µA.

Exploiting Lua 5.1 on 32-bit Windows

The following Lua program generates a Lua bytecode program called ignore-unsigned-sga.fnt, which in turn loads a DLL from within an extremely locked down Lua 5.1 sandbox in a program called RelicCOH2.exe. The remainder of this document attempts to explain how this program works by a whirlwind tour of relevent bits of the Lua 5.1 virtual machine.

if string.dump(function()end):sub(1, 12) ~= "\27Lua\81\0\1\4\4\4\8\0" then
  error("This generator requires a 32-bit version of Lua 5.1")
end

Port Forwarding in Mavericks

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.
