Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
You can get the list of installed codecs with:
'use strict'; | |
var profiler = require('v8-profiler'); | |
profiler.startProfiling(); | |
// ... | |
var cpuProfile = profiler.stopProfiling(); | |
require('fs').writeFileSync(__dirname + '/foo.cpuprofile', JSON.stringify(cpuProfile)); |
export class HttpClient { | |
constructor(defaults) { | |
this.defaults = defaults; | |
this.interceptors = []; | |
this.activeRequestCount = 0; | |
this.isRequesting = false; | |
} | |
addInterceptor(interceptor) { | |
this.interceptors.push(interceptor); |

Hi Nicholas,
I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:
The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't
var catHeight = 150 // 150 | |
var catOffset = 200 | |
ctx.fillStyle = '#002E68' | |
ctx.fillRect(0, 0, ctx.canvas.width, ctx.canvas.height) | |
// rainbow | |
var rainbowColors = [ | |
'#FF0000', |
Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.
This mini-rant came on the heels of an interesting twitter discussion: https://twitter.com/kennwhite/status/591074055018582016

When I just started using RxJS with React, I was subscribing to observables in componentDidMount
and disposing subscriptions at componentWillUnmount
.
But, soon I realised that it is not fun to do all that subscriptions(that are just updating property in component state) manually, and written mixin for this...
Later I have rewritten it as "high order component" and added possibility to pass also obsarvers that will receive events from component.
