A simple way to execute a function with a time limit and an isolated context – useful for maintaining resource availability on platforms that allow multiple HTTP APIs to share infrastructure.
(function generateContext() {
var _startTime = Date.now(),
_timeout = 10000,
_timedOut = false,
_finish = function(error) {
clearTimeout(_timeoutTimeout);
_endTime = Date.now();
_totalExecutionTime = _endTime - _startTime;

My dream-code (just an idea) for how video append request failure can be handled.

Post Sequence

A dream-class that handles sequential-request streaming.

Features

  • POSTs multipart request bodies
  • Caches all requests
  • Failed request are retried immediately within a specified time window
  • If >10% of requests fail during the stream, the entire post sequence is cached for later retry under conditions of greater reliability.

danscan / deepProperties.js
Created October 12, 2013 07:23
I was looking for a short, simple way to set and get deep properties in a single line in javascript, and after not finding anything I decided to see how short I could make these methods. Enjoy.
// Set deep property
function setProperty(p,v){p=p.split('.'),i=0,w=("string"===typeof v?'"'+v+'"':v);while(p[i])eval(p.slice(0,++i).join('.')+'='+(p[i]?"{}":w));return v}
// Example
setProperty('some.really.deep.property', 'now exists'); // "now exists"
// Get deep property
function getProperty(p){p=p.split('.'),v=this;while(p[0]&&v){v=v[p.shift()]}return v}
// Example
getProperty('some.really.deep.property'); // "now exists"
