| // In mediump, there are two problems computing 1.0 - NoH^2 | |
| // 1) 1.0 - NoH^2 suffers floating point cancellation when NoH^2 is close to 1 (highlights) | |
| // 2) NoH doesn't have enough precision around 1.0 | |
| // Both problem can be fixed by computing 1-NoH^2 in highp and providing NoH in highp as well | |
| // However, we can do better using Lagrange's identity: |

This is a quick-and-dirty guide to setting up a Raspberry Pi as a "router on a stick" to PrivateInternetAccess VPN.
Install Raspbian Jessie (2016-05-27-raspbian-jessie.img) to your Pi's sdcard.
Use the Raspberry Pi Configuration tool or sudo raspi-config to:
