Things to commit just before leaving your job
// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.
//
// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

var pixelHeight:UInt = CGImageGetHeight(imageRef);
var bitmapBytesPerRow:UInt = (pixelWidth * 4)
var bitmapByteCount:UInt = (bitmapBytesPerRow * pixelHeight)
var colorSpace:CGColorSpace = CGColorSpaceCreateDeviceRGB()
