Installing Arch Linux with Full Disk Encryption

If you're aiming for a seamless Arch Linux installation in UEFI mode, follow along as this guide will walk you through the process step by step. We'll be using LUKS (Linux Unified Key Setup) and LVM (Logical Volume Manager) partitions on LUKS to achieve full disk encryption.

Note: I have updated this doc for UEFI mode. For those with BIOS/MBR systems, you can refer to the previous version, but keep in mind that it might be outdated and no longer accurate.

If you're only interested in installing Linux and not setting up dual boot with Windows, feel free to skip the Windows-related sections.

"The common wisdom of "don't use conditionals in shaders" is one of my biggest frustrations with how shaders are taught.
step(y, x) _is_ a conditional! It compiles to identical code as:
float val = (x >= y ? 1.0 : 0.0)
or
float val = 0.0;
if (x >= y) val = 1.0;"

// Performing shader divisions without diving *rcp = approximation of 1/x
float myDividedVal = myValToDivide * rcp(myDivider);

--
-- uses debug.sethook and a timer to break out of infinite loops in lua code within Hammerspoon
--
-- Haven't had any problems with it or false positives, but YMMV -- standard disclaimers, etc.
--
-- Updates 2015-12-21:
--      should play nicely with other hooks by storing info about it and chaining
--      you can force an "immediate" break by holding down CMD-CTRL-SHIFT-ALT-CAPSLOCK-FN all at once
--          you'll need to remove "and mods.fn" where noted below if your keyboard does not have this
--          modifier (non-laptops, I suspect)
