Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

Installation

The Ruby Way! (Fun)

/*
A few things to note about USSD:
USSD is session driven. Every request we send you will contain a sessionId, and this will be maintained until that session is completed
You will need to let the Mobile Service Provider know whether the session is complete or not. If the session is ongoing, please begin your response with CON. If this is the last response for that session, begin your response with END.
If we get a HTTP error response (Code 40X) from your script, or a malformed response (does not begin with CON or END, we will terminate the USSD session gracefully.

using visual studio 2013 or Greater

in the projects window choose web under C#

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.
