I used ngrok pretty heavily a couple months ago for a period of weeks and it never never down when I was using it. This is the first time I've ever seen ngrok (service or site) down.
I agree that putting all that logic and template vars into a template is confusing. Hard to create mocks of what the HTML should actually be structured like. Im using Jade so I can be terse and pre-compiling the templates. While in my Backbone application, I apply DOM-like rendering with Plates.js.
I dont think it's clear yet; changes to the network may only require a change in software to get this VoLTE function. The document suggests Verizon is testing this, but where did he get that info? There is no footnote about it. Also, would the phone even support it?
Sounds a lot like webOS; huge amounts of potential, only to be plagued by 'being ahead of the game'. Probably still 5 years out, sadly. I really like the idea of a JavaScript OS.
Why was webOS not mentioned in the article? They have a very nice linux stack, telephony, and radio interfaces as well. Not to mention it's been open sourced (both OS and framework)
