NOTE: This was a great hack in days gone by, but now both Apple and Google have improved their support for custom protocol handlers. Licensed under the WFTPL http://www.wtfpl.net/txt/copying/

An ultra-small URI parsing function that accepts a URI-like string & returns an object with all the string properties of the native Location object for that string. Works using native property detection, without received wisdom (ie dictionaries, inference, etc).

Using cached promises for better resource use
# We have a function that loads some resource. It might get called multiple times by our application, for example a web server.
# We use a stored promise to serve as both a cache and a hook for multiple callers to get the same result
# JavaScript version at the bottom
Q = require 'q'
loadPromise = null
doLoad = ->
if not loadPromise
# get a fresh result
loadPromise = Q.delay(1000).then -> Date.now()
# after 1 second clear cache

rexguo / Using GL_OES_EGL_image_external on Android
Created September 25, 2013 07:11
1. The texture target needs to be GLES20.GL_TEXTURE_EXTERNAL_OES instead of GL_TEXTURE_2D, e.g. in the glBindTexture calls and glTexParameteri calls.
2. In the fragment shader define a requirement to use the extension:
#extension GL_OES_EGL_image_external : require
3. For the texture sampler used in the fragment shader, use samplerExternalOES instead of sampler2D.
Everything below here is all in the C code, no more Java.
4. In the C code, use glEGLImageTargetTexture2DOES(GL_TEXTURE_EXTERNAL_OES, eglImage) to specify where the data is, instead of using glTexImage2D family of functions.
